This application claims the priority based on Chinese patent application No. 201010104259.2, filed January 29, 2010, the State intellectual property office of the PRC. All contents of the specified application is included in the materials of the present application by reference.

The technical field

The present invention relates to the field of construction and building technologies, and in particular to concrete building with a light steel surround frame and the method of its construction.

Prior art

In the field of building technology of concrete structures can be used not only for low-rise and high-rise construction, but also for prefabricated buildings and, accordingly, find wide application.

For concrete, poured in place, may require steel reinforcement and formwork installed in place that requires hard work and lengthens the period of construction.

Pre-cured composite wall components are manufactured at the plant and collect on the spot. However, because of the need to address the tight connection between prefabricated elements and water infiltration through the joints between prefabricated elements, construction costs can be high.

In the published patent application China CN A described sostav the e concrete-framed building with steel mesh and the method of its construction, where the steel frame is used holodnokatanuju thin steel, and traditional wood or steel formwork replace steel mesh. Original steel mesh is manufactured at the factory and mounted in a steel mesh frame in place. Then in place to make the pouring of concrete for durable wall structure. However, this construction has the following disadvantages.

First, steel grating profile used in the mesh frame is holodnokatanuju detail of a thickness of 1.0 to 4.0 mm and C-shaped, U-shaped or Z-shaped cross-section. In the Col between two parallel angled ribs are formed and uniformly distributed openings. On the periphery of each aperture is formed reinforcing edging, which is between two adjacent openings forms a U-shaped jumper. The process of manufacturing steel grating profile is quite complex. Openings openings need to punch stamp in thin steel sheet, and then to produce cold bending on a separate device. Depending on the percentage of square openings in the total area of steel bar grating profile, the amount of scrap steel sheets that are sent to waste, can reach 10-15%. Moreover, for the manufacture of steel grating profile may require special manufacturing the th line, that will increase the cost of production.

Secondly, used for frame steel mesh is flat net, get cold stamping a galvanized steel sheet with a thickness of 0.3 to 0.6 mm On a flat grid formed by the threads of the mesh in the form of convex strips arranged in parallel at a given distance, and steel mesh is fixed on the surface of the steel skeleton of the protruding parts of the thread strips. Steel mesh is not taking on some of the structural loads and is simply used as formwork, which can cause an increase in the cost of construction and increase the intensity of the structure. After curing of the concrete on the surface of the steel mesh may require plastering for leveling the surface, which increases the complexity of the process.

In another published patent application China CN A described concrete building with a cast of spatial farm and the method of its construction. However, the method applies a permanent formwork, which cannot be reused, which may increase the cost of construction. In addition, since the casing cannot be removed, it is inconvenient to determine the density of hardened concrete.

Concrete building with a light steel surround frame according to the present invention will be described hereinafter with reference to the drawings.

As shown in Figure 1-5, concrete building with a light steel surround frame according to the present invention contains wall surround light steel frame 1, volumetric light steel frame 2 panel beams and concrete.

As shown in Figure 3, the volumetric light steel frame 2 panel beams connect with wall surround the light steel frame 1, forming a volumetric light steel frame construction section. Concrete is poured into a volumetric light steel frame construction section. The removable casing 3 mounted on volumetric light steel frame construction section before pouring concrete, formwork 3 is selectively removed after curing of the concrete for re-use.

It should be noted that the expression “casing 3 is selectively removed after curing concrete” means that such a choice may depend on the requirements of the project. For example, in one case, the casing 3 on the outer side of the wall surround light steel frame 1 forming the outer wall of a concrete building with a light steel surround frame, may not be removed, and to remain constant, and therefore, the insulation panel is ü 8 can be attached to the casing 3 on the outer side of the wall surround light steel frame 1, forming the outer wall of a concrete building with a light steel surround frame. That is, an insulating layer placed on the outer wall of a concrete building with a light steel surround frame, thus improving the heat-insulating protection of the building. However, the casing 3 under volumetric light steel frame 2 panel beams and formwork 3 walling volumetric light steel frame 1, which do not form the outer wall of a concrete building with a light steel surround frame, can be removed. Of course in another case can be removed all formwork 3.

Each of the wall frames 1 and frames 2 panel overlap contains a welded mesh reinforcement 4 and many steel grating profiles 11. Steel grating profiles 11, located at a distance from one another, and each of them has many stretched holes 113. To connect multiple steel grating profiles 11 together, they are welded to welded mesh reinforcement 4.

Each steel grating profile 11 consists of two parallel angled ribs 111 and many connecting jumpers 112. Two corner edges 111 and jumpers 112 is made as a single part. Themselves jumpers 112 and holes 113 are formed between them stretching two angular edges 111.

The concrete building according to the invention, the wall surround EHCI steel frame 1 and a volumetric light steel frame 2 panel beams formed by welding together the welded mesh reinforcement 4 and several steel grating profiles 11. Many jumpers 112 and a lot of stretched holes 113 are formed by stretching the two corner edges 111, so that the steel grating profile 11 can simplify manufacture, to save materials and costs, time, and investments in industrial equipment.

In some versions, concrete building with a light steel surround frame can be multi-storey, as shown in figure 2. For example an eight-storey building. Each floor of a concrete building with a spatial light steel frame is formed by a single layer one-piece construction block, and each solid building block is formed by a horizontal junction of one or more building sections. For example, in a constructive variant, shown in Fig.1-2, one solid building block formed ten construction sections.

Each construction section is formed by pouring concrete one volume of lightweight steel frame. The framing section, formed one wall surround the light steel frame 1 and one volumetric light steel frame 2 panel overlap. Some solid building blocks sequentially set one upon the other, form a multi-storey concrete building with a light steel surround frame in which the wall of the frame 1 of the upper tier of the whole is the main building block is attached to stenosoma the frame 1 adjacent the lower tier solid building blocks. Wall frame 1 upper tier one-piece building blocks can be connected to the wall of the frame 1 adjacent the lower tier solid building blocks, for example, the connecting element. The bottom edge of the wall of the frame 1 of the lower tier solid building blocks mounted on the Foundation 13. The upper edge of the wall of the frame 1 of the upper tier one-piece building blocks connected with the frame 2 panel beams, which serves as a roof.

In some versions, the frame 2 panel beams can connect with wall frame 1 by welding with the formation of bulk lightweight steel frame construction section. You can also frame 2 panel overlap to connect with wall frame 1 connecting elements.

In other embodiments, as mentioned above, the casing 3 can remain on the outside wall surround light steel frame 1, forming the outer wall of a concrete building. In other words, after curing concrete, formwork 3 on the outer side of the wall surround light steel frame 1 forming the outer wall of a concrete building, may not be removed, and an insulating panel 8 may be attached to the casing 3, thereby improving the heat-insulating protection of the building.

In one case, as shown in figure 4, for example, each of the steel lattice about the Ile 11 walling in volumetric light steel frame 1 and a volumetric light steel frame 2 panel beams can be manufactured from a single steel sheet, by applying many of the slots between the two corner edges 111 in the longitudinal direction (i.e. the left and right direction in figure 4) angular edges 111 and the subsequent stretching of the two corner edges 111 in the transverse to the corner edges 111 direction (i.e., the upper and lower direction in figure 4), so between the two corner edges 111 are formed many jumpers 112 and a lot of stretched holes 113, limited ridges 112,. Thus, the steel grating profile 11 can be very simple to make, save material, reduce the time and effort.

It should be noted that the design of the wall of the frame 1 is essentially the same as frame 2 panel overlap, except that before concrete pouring removable casing 3 mounted on two sides of the wall of the frame 1, while the removable casing 3 mounted on the lower surface of the frame 2 panel overlap.

In some versions, can be designed doors and Windows of the building depending on the project requirements. For this reason, in areas of wall surround light steel frame 1 provide door and window openings in order to place the doors and Windows of the building, respectively. On the two sides respectively of the doorway and window opening, ostavlen the x in the horizontal direction on the sections of wall surround light steel frame 1, have fringe elements 6. Each bordering element 6 includes a longitudinal reinforcing steel rods and horizontal clamps or contains vertical reinforcing bars, steel vertical profiles and horizontal clamps. In addition, over door and window openings are placed connecting beams 7. Each connecting beam 7 has a horizontal reinforcing steel rods and vertical tails. In accordance with the project in volumetric light steel frame 2 panel beams can be pre-formed stairwell.

As shown in Figure 5, the welded mesh reinforcement 4 can be manufactured by welding reinforcing steel rods 41, horizontally-oriented, and reinforcing steel rods 42 vertically. Welded mesh reinforcement 4 weld with many spaced from one another steel bar grating profiles 11, each having many stretched holes 113, thus forming wall surround light steel frame 1 and a volumetric light steel frame 2 panel beams, respectively.

In some versions, the insulation panel 8 is placed on the outer wall of a concrete building with a light steel space frame may be a composite insulating panel. As shown in Fig.6, isol the operating panel 8 includes (sequentially in the direction from inside to outside) of the insulating layer 801 is made of polystyrene or mineral wool, layer protivorechivogo composition or a protective layer 802 panels and decorative surface layer 803.

Each one-piece construction block formed by a horizontal junction of one or more building sections. Each building section are made by pouring concrete surround light steel frame construction section formed by one wall surround the light steel frame 1 and one volumetric light steel frame 2 panel overlap. Some solid building blocks, the sequence is correctly set on one another and form a multi-storey concrete building with a light steel surround frame. Volumetric light steel frame 2 panel beams can connect with wall surround the light steel frame 1 by welding or connecting elements.

As already mentioned, each steel grating profile 11 is formed by applying a set of narrow longitudinal slits between the two corner edges 111 and further stretching of the two corner edges 111 in the transverse direction.
