Description

Insulation wall keel skeleton

technical field

The invention relates to a thermal insulation wall keel skeleton, which belongs to the field of thermal insulation wall construction.

Background technique

At present, in the process of traditional thermal insulation wall construction, it is necessary to use a keel frame to fix the insulation board of the outer wall. The skeleton is composed of the insulation board and the inner and outer layers of steel wire mesh. In order to ensure that the skeleton is firm and the insulation board is positioned and fixed in a suitable position, a large number of straight-web wires are usually welded between the inner and outer layers of steel wire mesh. The cost of the skeleton is high, and the material consumption is large. On the other hand, the straight-belly wire has thermal conductivity. Therefore, too many straight-web wires will inevitably cause problems such as fast heat conduction and poor thermal insulation effect of the wall. At present, these problems have not been well resolved.

Contents of the invention

Based on the above deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a thermal insulation wall keel frame with firm and reasonable structure, low cost, which can improve the thermal insulation effect of the thermal insulation wall and save energy.

In the thermal insulation wall keel skeleton of the present invention, the skeleton body includes a thermal insulation board and two inner and outer layers of steel wire mesh located on both sides of the thermal insulation board, and the inner layer of steel wire mesh, the insulation board and the outer layer of steel wire mesh are connected by abdominal wires , the abdominal wire adopts a U-shaped structure, the U-shaped structure is hooked to the steel wire of the inner layer of steel wire mesh, and the two ends pass through the insulation board and welded with the outer layer of steel wire mesh, and the insulation board and the inner and outer layers of steel wire mesh pass through The connecting pieces are connected and fixed, and corner fixing pieces are installed on the four corners of the skeleton body.

By adopting the abdominal wire of the U-shaped structure, first hook the U-shaped structure to the steel wire of the inner steel wire mesh, and then weld the two ends of the U-shaped structure through the insulation board and the outer steel wire mesh. The fixing effect is better than that of the traditional straight The abdominal wire is much better, so the inner and outer layers of steel wire mesh can be fixed firmly with a small amount of abdominal wire, thereby greatly reducing the amount of abdominal wire, which not only reduces the production cost, but also reduces the heat conduction medium, which reduces the thermal conductivity and makes The thermal insulation effect of the thermal insulation wall is effectively improved to achieve a good energy-saving effect; by setting the corner fixing parts on the four corners of the frame body, it is possible to prevent the frame deformation during the process of placing or transporting the keel frame.

When making the keel skeleton, it is necessary to hook the two ends of the U-shaped structure to the steel wires of the inner steel wire mesh, then pass the two ends of the U-shaped structure through the insulation board, and weld them to the outer steel wire mesh, and then the U The two ends of the type structure are bent into flanging, and the flanging is hooked on the outer steel wire mesh from the outside. The abdominal wires of the U-shaped structure can be anchored on the inner and outer steel wire mesh sheets by flanging, and there will be no open welding of the abdominal wire welding points during the pouring process, thereby ensuring that the poured outer layer of the thermal insulation wall is consistent with the The load-bearing walls of the interior walls become one.

The connector adopts a U-shaped card, and the U-shaped card is stuck on the insulation board, and its two ends are welded on the steel wires of the steel wire mesh facing the U-shaped card slot. The insulation board is fixed in a proper position and firmly fixed by the U-shaped card, which can ensure the gap between the inner and outer steel wire mesh sheets and the insulation board, and ensure the building quality.

Each corner fixing piece includes steel bar one, steel bar two, and steel bar three, and the three steel bars are all arranged between the inner and outer steel wire mesh sheets and one end is welded on the corner of the outer layer steel wire mesh sheet; the steel bar one and the inner layer steel wire mesh sheet The plane is vertical, and the other end is welded to the inner steel wire mesh; the other end of the steel bar 2 is welded to the outermost transverse steel wire of the inner layer steel mesh, and the angle between the second steel bar and the outermost transverse steel wire is 40-50 degrees; The other end of the steel bar three is welded to the outermost longitudinal steel wire of the inner steel wire mesh sheet, and the angle between the steel bar three and the outermost longitudinal steel wire is 40-50 degrees. Steel bar 1, steel bar 2 and the outermost horizontal steel wire of the inner layer steel wire mesh form the most stable triangle structure. Similarly, steel bar 1, steel bar 3 and the outermost longitudinal steel wire of the inner layer steel wire mesh form the most stable triangle structure, thus It can ensure the stability of the four corners of the skeleton body and prevent deformation.

In addition to the above, the bottom width of the U-shaped structure is 2cm to 4cm; the bottom width of the U-shaped card is 4cm to 6cm; because the keel skeleton of the thermal insulation wall in this structure is firm and reliable, the grid size of the inner steel wire mesh can be adjusted. From the traditional 5cm×5cm to 12cm×18cm, the grid size of the outer steel wire mesh can be increased from the traditional 5cm×5cm to 6cm×12cm, which can greatly reduce the steel wire consumption of the inner and outer steel mesh, and reduce the manufacturing cost.

The beneficial effect that the present invention has compared with prior art is:

The structure of the keel skeleton of the thermal insulation wall is reasonable, and by adopting the U-shaped structural abdominal wire with good fixing effect, the amount of abdominal wire can be greatly reduced, the cost is low and the thermal conductivity is reduced, and the thermal insulation effect of the thermal insulation wall is effectively improved; The keel frame of the thermal insulation wall is firm and reliable, which can increase the steel wire spacing of the inner and outer steel wire mesh sheets, thereby greatly reducing the steel wire consumption of the inner and outer layer steel wire mesh sheets and reducing manufacturing costs; the corners set on the four corners of the frame body Fixtures can prevent deformation of the keel frame.

As shown in Figures 1 to 4, the keel skeleton of the thermal insulation wall, the skeleton body includes the thermal insulation board 4 and the inner and outer layers of steel wire mesh sheets located on both sides of the thermal insulation board 4, the inner layer of steel wire mesh sheet 6, the insulation board 4 and the outer layer. The first layer of steel wire mesh 2 is connected by the abdominal wire, which adopts U-shaped structure 7. When making the keel skeleton, it is necessary to hook the two ends of the U-shaped structure 7 to the steel wire of the inner layer of steel wire mesh 6, and then hook the U-shaped The two ends of the structure 7 pass through the insulation board 4 and are welded to the outer steel wire mesh sheet 2, and then the two ends of the U-shaped structure are bent to form a flange 3, and the flange 3 is hooked on the outer steel wire mesh sheet 2 from the outside (The U-shaped structure after both ends are bent to form flanging is shown in Figure 5). The bottom width of the U-shaped structure 7 is preferably 2cm to 4cm, and the insulation board 4 and the inner and outer layers of steel mesh are connected and fixed by connecting pieces , corner fixing parts 1 are installed on the four corners of the skeleton body.

By arranging the corner fixing pieces 1 on the four corners of the skeleton body, the deformation of the skeleton can be prevented during the process of placing or transporting the keel skeleton. The corner fixing part 1 in the present embodiment adopts the following preferred scheme: the corner fixing part 1 includes steel bar one 12, steel bar two 9, and steel bar three 10, and the three steel bars are all arranged between the inner and outer steel wire mesh sheets and welded at one end On the corner of the outer steel wire mesh sheet 2; the steel bar one 12 is perpendicular to the plane where the inner layer steel wire mesh sheet 6 is located, and the other end is welded on the inner layer steel wire mesh sheet 6; the other end of the steel bar two 9 is welded to the inner layer steel wire mesh sheet 6 On the outermost horizontal steel wire 8, the angle between the second steel bar 9 and the outermost horizontal steel wire 8 is 40-50 degrees (preferably 45 degrees); the other end of the steel bar three 10 is welded to the outermost longitudinal direction of the inner steel wire mesh On the steel wire 11, the angle between the steel bar 3 10 and the outermost longitudinal steel wire 11 is 40°-50° (preferably 45°). Steel bar one 12, steel bar two 9 and the outermost transverse steel wire 8 of inner layer steel wire mesh sheet 6 form the triangle with the most stable structure, likewise, steel bar one 12, steel bar three 10 and the outermost longitudinal steel wire 11 of inner layer steel wire mesh sheet 6 The triangle with the most stable structure is formed, so as to ensure the stability of the four corners of the skeleton body and prevent deformation.

The connector adopts U-shaped card 5 (as shown in Figure 6). The width of the bottom of the U-shaped card 5 is preferably 4cm to 6cm.

Since the abdominal wire fixing effect of the structure described in the present invention is much better than the traditional straight abdominal wire, the inner and outer layers of steel wire mesh can be fixed firmly with a small amount of abdominal wire, thereby greatly reducing the amount of abdominal wire, which not only reduces The production cost also reduces the heat conduction medium, reduces the thermal conductivity, reduces heat dissipation, effectively improves the thermal insulation effect of the thermal insulation wall, and achieves a good energy-saving effect; the abdominal wire of the U-shaped structure 7 can be anchored inside by the flanging 3 On the outer two layers of steel wire mesh, there will be no open welding of the abdominal wire welding points during the pouring process, so as to ensure that the poured outer thermal insulation wall and the inner wall load-bearing wall are integrated. Because the thermal insulation wall keel frame of this structural form is firm and reliable, the grid size of the inner steel wire mesh 6 can be increased from the traditional 5cm×5cm to 12cm×18cm, and the grid size of the outer steel wire mesh 2 can be changed from the traditional The original 5cm×5cm is increased to 6cm×12cm, which can greatly reduce the steel wire consumption of the inner and outer steel mesh sheets and reduce the manufacturing cost.
