The present invention relates to a method of installation of steel frame construction, the frame contains at least the horizontal beams and vertical support.

The present invention also relates to a device for implementing the method.

Steel frame buildings is a structure mainly consisting of vertical supports and horizontal load-bearing beams. Additionally, the use of lattice structures with different types of diagonal braces, triangular patterns and such. Lattice designs are often made in advance of the installation of the modules in a production shop. Set sizes and frames are designed for each case separately. The frame may be, for example, a part of the carrier frame structure buildings and to perform the function of linking constructions, for example, together with reinforced concrete structures. The frame also may function as a self-supporting structure. The advantages of the steel frame, among others, are fast Assembly, in exactly the specified size parts, so they can be easily attached to each other, and in good bearing capacity in relation to the size and weight of the frame. The flexibility of the design of the steel frame shown in thin and low con is trucktech and easy connections. Steel frame makes it possible to achieve a high accuracy of dimensions, for example, parts relating to the facade of buildings.

On the construction site, steel frames are transported and moved by the same lifting and transporting devices, and other components, that is, either stationary cranes or mobile transporting cranes, both of which raise the load by means of the lifting hook or other transporting means, suspended by ropes, and the weight hangs freely from the ends of the cables. During such lifting of the load is free to swing to the sides, and supports or beams should be directed precisely at their places by hand. Thus, installation of parts required in addition to the crane operator, at least one of an applicator for directing beams or supports and to perform the required attachment. The most common ways of mounting structures are welding and a variety of bolted connections. The frame is assembled from separate floors, and a crane is used to move the supports and beams in their respective locations. Screw mount can be easily installed at their place, and welded connections can also be preset for final fixing by welding, and Bo who you meet, and the final welding is performed in due time, after the part is lifted into place. However, regardless of the stage which is the final fixing, mounting frame work involves a lot of work, because the supports and beams should be directed to their seats by hand. Precision crane with freely suspended managed by a cable, is not sufficient for placement of parts without manual labor.

Object of the invention is to provide a new type of method and device for installation of steel frame construction, preferably for installation of the steel frame, comprising vertical supports and horizontal beams.

The invention in some cases can also be used to build pre-fabricated lattice structures.

The invention is based on the moving parts of the frame by means of a gripping device located suspended using a rigid system of arrows, while the gripper has at least two degrees of freedom relative to the end of the boom.

In accordance with one embodiment of the invention the gripper can be rotated at least around a vertical axis and to rotate around a horizontal axis.

In accordance with one preferred embodiment to the Delta unit is a working cylinder, forest machines, provided with the exciting means.

In accordance with one embodiment of the system of the boom is a boom of an excavator or harvesting machine.

In accordance with another embodiment the device is a point of positioning, whereby the location of the gripping device and the parts attached thereto, can be calculated by the positioning system.

Moreover, in accordance with one embodiment of the invention, at least one of the following actuating devices attached to the gripping device: welding head positioning system, ultrasonic inspection equipment and Luggage.

Moreover, in accordance with one preferred embodiment the device is provided with autopilot, whereby the part can be automatically transported to the place, for example, ordered via remote control.

The invention is defined in more detail in the claims.

Significant advantages are achieved by means of variants of implementation of the invention.

By means of the invention, the frame Assembly is faster and less time consuming in comparison with previous methods. Accommodation ka the DOI supports, beams or pre-fabricated parts can log on to the system control device, starting from the construction drawings, whereby parts are automatically correctly placed. The system can include a system log, through which is possible to control the exact sequence of installation and installation of parts in the appropriate positions. If the gripper is provided, for example, with automatic welding, the mounting frame can be performed very quickly and efficiently. Moreover, automatic control joints makes it possible to create an archive file for the product, having accurate information about the frame structure for control design and for the entire operational life of the building. Thus, it is easy to ensure that the frame has been mounted in accordance with the construction drawings and specifications. Slightly modified harvesting machine can be used as the conveying device, with the removed cutting and branching means, and provided with a suitable exciting device for securing the supports and beams, and other accessories falling under the scope of the invention.

The invention can also be used in combination with traditional single-beam under the set aside by the Russian crane with a lattice frame structure, if the vertical beam is attached to the carriage cross beam and the vertical beam is provided, either directly or through articulated beams with a gripping device having at least two degrees of freedom. Thus, it is easy to achieve a relatively wide workspace.

Is also possible to apply the invention in such a way that it was used only for installation of supports or beams. Especially when the gripper is based on the harvesting machine, it can convey the necessary supports and beams, as many forest machines clearly have the boot compartment.

Below, the invention is examined by means of examples and reference to the accompanying drawings.

Figure 1 shows one device, in accordance with the invention.

Figure 2 shows another device, in accordance with the invention.

The device shown in figure 1, contains a traditional, well-known tractor 1 and the transporting beam system 2 attached to it. The end of the beam system 2 is made with a breathtaking device 3 for gripping the supports 4. In this example, the system 2 arrows contains the first part 5 of the boom attached to the tractor 1, the first part of the boom attaches to the system 2 arrows to the tractor, predpochtite is) through swivel around the axis of which the first part 5 of the boom and the whole system 2 arrows attached thereto can be rotated around the vertical axis of the swivel. The governing body of the hinge may be a pair of hydraulic cylinders, hydraulic motor or other suitable actuator. The second part 7 system 2 arrows is a retractable boom with variable length. The angle of the second part of the boom relative to the horizontal level may vertically be changed by means of a hydraulic cylinder 6. The third part 8 arrows placed at the end of the second part of the boom attached to the end of the second part 7 of the boom by means of the swivel 10. The third part 8 of the boom can be rotated around the hinge connection 9 by means of a hydraulic cylinder 10. The end of the third portion 8 of the boom is provided with a gripping device 3 attached through a swivel 11, while the gripper has the ability to rotate around the hinge connection 11 in the direction of the longitudinal axis of the third portion 8 of the boom by means of a hydraulic cylinder 12. An exciting device 3 also includes actuators for turning the exciting means of a gripping device 3 around the horizontal axis.

Location is rely, described above are well known, for example, excavators and forestry machines, and the person skilled in the art can by means of these known devices to perform certain system conditions arrows with sufficient reach and capacity. System 2 arrows is intended for moving the gripping device 3 in a three-dimensional environment to a specific point, and this function can be performed by many types of systems boom. The gripper is designed to be the first to attempt and capture support 4 (see figure 1) or a beam. On the other hand, it is intended for positioning the end of the prop in exactly the appropriate place by means of a rotational movement around a horizontal and a vertical plane gripping device. The gripper also ensures that the location of the supports or beams was appropriate. In the example in figure 1 supports 3 are arranged horizontally, and the beam vertically. Construction norms and rules for steel structures include tolerances, for example, for maximum permissible angle of support. In order to regulate it is preferable to provide the gripper with sensors, through which can regulate the sterile angle, and the seat can be installed vertically.

The main difference between the device in figure 2, relative to the device shown in figure 1, is that here the legs 3 are transported in the boot compartment, mounted on the mounting device, whereby they can be easily captured. The machine can also be transported to other parts required for installation, and it can be built so that she could climb from one level of a building to another level. Lifting can be performed by advancing along the platforms or through, for example, hydraulic lifting jacks.

Through the above-described devices, a steel frame is mounted as described below.

The gripper 3 mounting device raises the support 4 by means of its gripping near its lower end, i.e. the end below, when installed in the frame. Bearing turns in a vertical position by means of a displacement system 18 arrows, and a gripping device 3, and it moves in its installation position, in this case, towards the upper end is mounted a support 14. New bearing 4 flips in a vertical position and moves toward the upper part 15 is mounted supports and lowered to support pore the STW bearing. In this example, the upper ends of the supports 15 are made with cones 15, thus, the lower end of the new support directed through the cone, fits easily on the top mounted bearing. The lower end of the cone is provided with a flange 16, which falls on the lower end of the new support 4 and which is also supported beam 17. Beam 17 is provided with a cutout for the ends 4, 14 feet. When the bearing is positioned in its place, it can be fixed. Any suitable connection may be used for fixing, but if the gripper 3 is provided with an automatic welding device, welding is a very preferred method of connection, whereby the connection will be immediately ready. The frame can be assembled by installing the first row of supports and then positioning at him cross-beams, and then set a different number of poles and the following beams. On the other hand, the beams can be installed by crane, construction sites, and through their hand direction, whereby it is possible to simultaneously install new bearings and immediately after this, the beams formed on the installation.

Pillars and beams can be directed to place a certain number of ways. The easiest sposobstvujet management device, starting with the cockpit setting device, and the machine operator directs support in its place. In this case, the auxiliary device is likely to be needed to control the positioning of the part in the appropriate place. The auxiliary device may be replaced by a camera placed at an exciting device or in a suitable place on the boom so that the operator can see the installation location. Another way is to place a homing-based points-leveling construction site. In this case, setting the device required positioning system, whereby the position of the gripping device and supports or beams attached to it, can be determined. One way to accomplish this is by placing a control point on the device at this point is regarding the point of leveling the construction site. Thus, the system control device calculates the position of the gripping device and the end of the prop on the basis of this point, and reliance is sent to its target point either automatically or by the operator using the display screen. The disadvantage of this arrangement is the error between the calculated position and the actual position is called any movement and errors in the moving system of the arrows. Greater accuracy is achieved at the location of the control points directly at an exciting device and its position relative to the point of leveling is determined by, for example, laser measurement. This provides the ability to accurately determine the position of the gripping device, and the flexibility of the boom or other inaccuracies move does not affect the positioning. Perhaps this way of positioning may allow automatic installation support, the operator of the device only specifies the command to the device for transporting the following support in its place. When this is combined with automatic welding, automatic docking and quality control, is a very effective system mounting frame, and the workmanship of the whole frame can be easily controlled.

An essential feature of the invention consists in that the gripper is moved through a rigid system of arrows. This means that the gripper and the part attached to it, constantly maintained during handling and installation. Thus, in transporting the device must not be present flexible supporting elements, or a freely rotatable swivel. In addition to visheopisannie arrows, one may consider the installation of rigid vertical arrows on the carriage cross beam crane construction site, the end of which is provided with a system of arrows, allowing sufficient space for the movement described above. The end of the rigid vertical beams can also be provided only with a gripping device, so that it could be directed in a vertical direction through the guides located on the vertical beam. Articulated beam system can also be attached to a guide or guides. The advantage of this arrangement lies in the wide space of the move made by crane construction site, but the lack of it, with large cranes, is the need for high, hard, vertical beams. Probably the vertical arrow should also be shortened, because the frame construction is mounted so that it had the space to turn around the assembled frame.

If the frame construction includes a lattice structure or the like, they must be specified capture point is designed to capture spectacular device. Can then be calculated location of the partial structure on the basis of this point or the composition of the first parts can be designed to place through the visual homing or may be sent by an auxiliary device.

SUBSTANCE: entire process of panel assembly from steel galvanised shapes takes place in building ways comprising a bed, mechanisation elements, electric equipment and two stands: a stationary and a mobile ones, along which carriages may move, setting various angles of inclination and height of the assembled panel relative to the horizontal plane, and the mobile stand itself may move along the building ways along the horizontal line, providing for the preset panel length. Carriages and the movable stand are controlled automatically from a control station. Assembly of panels in the building ways is started from installation of transverse shapes according to basic openings onto fixators of carriages of the stationary and movable stands and pulling of the shapes to the plates of the carriage shaft by rotating magnet handles. Then the movable stand is moved along the building ways along linear guides, keeping the length of the assembled panel. Then longitudinal profiles are installed between transverse ones and fastened at one side. Afterwards the carriages with a panel frame fixed on them are raised into the upper position and are rotated by 180. Then the carriages with the panel frame are lowered to the height convenient for assembly. Then shapes are fastened at the opposite side to form a stiff frame of the panel, and lining is installed on this side. Afterwards the frame with the lining is raised into the upper position, rotated by 180 and lowered down, the insulant is laid, and the lining is installed on the second side of the panel, the finished panel is removed from the building ways, with preliminary disconnection of magnets and removal of carriage fixators.

EFFECT: building ways design does not block up the working space around the frame of the assembled panel, leaves free access and approach to areas of assembly and makes it possible to perform assembly works at different levels without reinstallation of the assembled panel.

FIELD: construction.

SUBSTANCE: frame comprises horizontal beams and vertical supports. Parts of the frame are installed in place by means of at least one lifting device, at the same time at least one of frame supports is installed in place by means of a rigid boom system with the help of its displacement together with a gripping device attached to a boom system. The support rotates to the appropriate setting position by rotation of gripping facilities of the gripping device around at least two axes of rotation. Preferably a lifting device is based on a logging machine and may transport together with it materials required to manufacture and assemble the frame.

EFFECT: improved accuracy of frame elements installation.
