The device farm building elements

 

(57) Abstract:

The invention relates to the field of construction, in particular for supporting structures - trusses. The technical result of the invention is to increase the rigidity of the structure. The farm includes a plate, at least one belt and one or two lattices. Each grille is made of rods or wires or strips arranged in the longitudinal direction in the form of a zigzag line, the ends of the trusses manufactured as a single unit in the form of a monolithic part or connected to one another in a monolithic piece so that the intermediate region between the two trusses or between the belt and the plate of the farm is filled with this material. 3 C.p. f-crystals, 6 ill.

The device farm building elements for farms with open gratings, farms with two belts, trusses with two zones, at least one of which is cast, and belts for slab molded element with a lattice of rods, bars or rack material or with a lattice of rectangular plates or similar, perhaps the profiled collected diagonally similarly, the diagonal elements of the lattice in farms with open lattice, and thus forming an open lattice attached to the belt or to poiny farm, high hardness, hardening compounds as hardening and securing the trusses.

The present invention relates to a new design of all farms or zones and can also be used for other parts of the farm. It can also be used in the design of trusses with monolithic grating or gratings consisting of gratings, the thickness of which is less than the width of the belt, and with such lattices, which are equipped with openings to reduce weight.

This invention can also be used for farms with a lattice of rectangular plates or similar, perhaps the profiled collected diagonally similar to a diagonal parts of the lattice in lattice girders, which thus form an open lattice, for example, in accordance with the patent Sweden N 488312.

Farm with open gratings are usually exposed to the so-called shear forces. In the farm, or the element beam form, or in the slab with a belt designed as a farm with an open lattice with diagonals, United on the principle of zigzag, these diagonals are either stretching or compressing the load due to the displacement forces generated in the farm. If the study, in the same plane, these rods will be exposed to twisting forces acting in the direction arising from the fact that one of the diagonal rod is always stretched, and the second is always compressed, or Vice versa. Even a very slight deformation of the torsion has a huge impact on the deformation of the farm. The most desirable to obtain a device that would reduce the impact of such forces on the farm.

Farm with open arrays are also exposed to transverse forces acting on a farm in areas around fasteners. Walls often are at the top of the truss elements and the farm must be able to withstand the immense pressures that inevitably entails a reduction of the loads on the farm.

The difficulty of production farms with open gratings of optimal length, because for economic reasons, the manufacturers try to use the identical form, for example, with the same gaps between the curves. It is desirable to streamline the installation of all farms.

In addition, we are currently developing new technology for heating and ventilation of residential buildings, which consists in the supply of preheated air in the narrow opening at the base of the building, then this air is under niteline to heat the air. If serving heat pipe is placed along the external wall below the structural slab flooring, the air under the slab is also heated, the heated floors, and passing through the tube the air is heated, the heated areas of the home. It is desirable that the design allowed for the installation of such pipes and other installations of wiring the load-bearing parts.

Another way of monitoring the temperature of the air along the exterior walls is to hang curtains on the distance from the inner part of the outer wall, the top of the curtains seals the floor slab and belt. It is desirable to have a locking device to install the above screens.

In addition, we are currently developing new technology for the construction of multi-storey houses made of very light materials. For example, between the permanent forms of insulation of foamed plastic is placed so-called aerated concrete. The disadvantage of thus obtained the walls is poor soundproofing and what they can not withstand large loads.

For practical and technical reasons for achieving integrity in the casting and the valve between floors and to eliminate sound transmission, full-time elements of the decks on the racks and to avoid expansion of the slab inside the outer walls. The elements of the decks should be carefully anchored on the walls for transmitting transverse forces caused, for example, winds, and achieve the effect of diaphragms in slab flooring to give the building stability.

Manufacturers of houses from wood blocks are often used boom lift walls of various heights, even if the rooms are the same height. Elements walls of wooden houses are normally installed in structural floors, also made of wood. The latter also continue through the wall and exposed to cold air from the outside.

Therefore, it is necessary to find a solution for fastening, taking into account these requirements and minimizes the effects of thermal bridges using precast concrete parts.

The basis of the invention was based on the task to ensure the satisfactory functioning farm with open grate, more or less resistant to deformation caused by the twisting forces. Especially susceptible to this farm with open gratings consisting of diagonals that are in the same plane. Specifically in bending twisting force is called on twisting the connection between the lattice and the belt due to the directions of the forces: one force stretching and basic structure, that simultaneously provides load-bearing properties and is also used as an area for installation of electrical wiring and plumbing equipment, installations for Central vacuum processing and similar installations as well as installation of outboard equipment for suspended ceilings or equipment in tunnels used for installations.

Testing has shown that even if the cables of the lattice and the great belt anchoring element of the long span and subjected to heavy loads still does not have sufficient resistance to twisting deformation, while belt, as seen from the side view, is exposed to a sinusoidal deformation.

Especially important is the feature of this invention that it is possible to reduce the load on the belt and thus to increase the strength of the farm and to improve its properties of resistance to twisting deformation.

This invention allows the installation of a heating circuit and speed control air flow along the outer wall. Also there is a similar possibility of installation of electrical wiring and cables for stereo audio, computer networks, etc., with access from above.

The design of the mount is the problem of strengthening the above truss structures solved by constructing all of the farm as a monolithic structure or component connections in monolithic structure, in a homogeneous material, such as steel, wood, plywood, or composite, or design through the fill entirely, or almost entirely, for example concrete or composite, coupled with belts or belt and slab, respectively.

In accordance with the present invention the ends of the chord is given a special configuration to enable installation of the above equipment and the elimination of thermal bridges. Method of strengthening the walls with low bearing capacity is also listed.

In this situation, the flooring elements are assembled so that the turning of the slab is at the top. Possibility of installation of the equipment is in the manufacture of farm with special ends longer than the slab, which serves as the attachment. The slab has a smaller size than the span between the walls, thus there is a gap between the outer wall and the slab. Notch above are on the top and on the end of the slab. This design allows you to install the wiring and tubing from the top of the structural deck instead of having to install them from below with thread.

This can be achieved, because the element that the new application should serve as part of the installation, Spry.

Since the distance between the slab and the belt increases, the end of the farm increases, because in the present invention used in the intermediate gap. Even if the groove is for installations made at the top, for supporting still have sufficient strength. This is one of the advantages of the present invention.

The possibility of fixing curtains, etc. is provided at the supply end farm hollows may end-to-end at a distance from the inner part of the outer walls and top slab flooring.

Prevention of thermal bridges at the bases and fixture arrows lifting walls of different heights of different manufacturers is achieved by strengthening at the end of farm strong bolt of wood or other material with low thermal conductivity. This bolt and possibly also the end of the farm can support Lejeune wood boards for one wall. Under Lejeune, you can put more crossbars as an additional support between the ends of the farm if they are at a great distance from one another.

Further, according to the present invention the ends of the farm is of special configuration to provide the above capabilities for installing and fixing the same to the etc. can be achieved when the supply end of the anchor farm solutions, which can be end-to-end to provide feed valve through the farm. Cast strip or beam, for example, of concrete, the walls inside, slightly lower in level with the structural deck can serve as a mount as well as the anchoring element to the wall.
