Description

A Composite Thermal Insulation Wall Using Prefabricated Reinforced Concrete Cross Hole Formwork Without Demolition

technical field

The utility model belongs to the field of building component design, in particular to a thermal insulation wall body for building.

Background technique

In order to solve the problem of house insulation, the widely used method is to install the insulation board on the surface of the building by pasting technology. Due to the limitation of construction conditions, there are problems that the insulation material is not firmly pasted, the paste speed is slow, and it is easy to fall off.

Contents of the invention

The purpose of this utility model is to overcome the shortcomings and deficiencies in the above-mentioned technologies, and provide a composite thermal insulation wall using prefabricated reinforced concrete intersecting hole templates without dismantling. The wall has the bonding strength of prefabricated reinforced concrete panels and thermal insulation panels High, fast assembly construction, good integration with the building, and low cost.

Features and beneficial effects of the utility model:

1) The prefabricated concrete cross-hole formwork and the insulation board with dovetail grooves are all produced in the factory, with a high degree of industrialization.

2) The on-site installation of the insulation board adopts dry construction, with accurate dimensions and fast installation speed.

3) When pouring concrete, the cement slurry flows out from the reserved holes in the formwork and penetrates into the dovetail groove behind the insulation board, so that the connection between the insulation board and the wall board is firm.

Detailed ways

A composite thermal insulation wall of the utility model that adopts a prefabricated reinforced concrete cross-hole formwork that does not need to be dismantled is described in detail in conjunction with the accompanying drawings and embodiments as follows:

The embodiment structure of the present utility model is shown in Figure 1, comprises the wall body that the plate shape prefabricated reinforced concrete cross hole formwork and the L shape prefabricated reinforced concrete cross hole formwork 1 combine, is arranged on the plate shape insulation board and the wall outer surface The L-shaped insulation board 2 has dovetail grooves 21 distributed on both surfaces of the insulation board, and also includes an anchor 3 that combines the prefabricated reinforced concrete board and the insulation board. The anchor 3 passes through the insulation board 2 and its tail extends to In the hole 11 of the reinforced concrete cross-hole template.

The embodiment of the reinforced concrete cross-hole formwork, taking the flat form as an example, its structure as shown in Figure 2, the holes in the plate formwork are composed of longitudinal through-holes 11 parallel to the formwork surface, transverse through-holes 12, and joints with the formwork surface Vertical holes 13 form cross passages in the template. Grooves 14 are formed around the sides of the reinforced concrete cross-hole formwork, and installation rings 15 are arranged on the top of the prefabricated reinforced concrete formwork.

The L-shaped reinforced concrete intersecting hole formwork of the utility model has the same structure as the flat plate formwork.

The thickness of the reinforced concrete cross hole formwork is 120mm to 360mm, the diameter of the cross hole hole is 60mm to 300mm, and the height of the reinforced concrete cross hole formwork is 2500mm to 5000mm.

The embodiment structure of the thermal insulation board 2 of the present utility model is shown in Fig. 3, which can be made by using existing profiles. Dovetail grooves 21 are distributed on both surfaces of the thermal insulation board, and each side of the thermal insulation board is provided with matching bosses. 22 or groove 23. When the L-shaped insulation board shown in FIG. 3 a is spliced with the flat-shaped insulation board shown in FIG. 3 b , the boss 22 on the adjacent side is inserted into the groove 23 to form a whole. The insulation board can be polystyrene board, extruded polystyrene board or modified phenolic board, etc. The thickness of the insulation board is calculated according to the requirements, generally from 20mm to 150mm.

The structure of the anchor piece embodiment of the present utility model is shown in Figure 4. The anchor piece of this embodiment adopts a thermal insulation anchor bolt, and the thermal insulation anchor bolt is composed of a plastic screw sleeve 41 and a metal screw nail 42. Yin screw pattern, the screw is inserted into it and merged with the screw sleeve to expand the screw sleeve.

The method for making the thermal insulation wall of the present utility model on the spot is described as follows:

1) Utilize existing technology to produce prefabricated reinforced concrete cross-hole formwork with cross holes inside and insulation boards with dovetail grooves (including flat formwork and L-shaped formwork), and transport them to the site;

2) Support the prefabricated reinforced concrete cross-hole formwork, and drill criss-cross holes on the outer surface with an interval of 200mm to 500mm. The diameter of the holes is 50mm-60mm. These holes communicate with the cross-hole holes of the wall formwork ( figure 1)

3) Cut the insulation boards with dovetail grooves shown in Figure 3a and Figure 3b into pieces according to the required size, and fix them one by one on the outside of the wall with anchors (Figure 1a).

4) When pouring concrete into the prefabricated reinforced concrete cross-hole wall formwork, a part of the cement slurry flows out through the cross-hole hole 13, fills and infiltrates into the pores 111 formed by the wall formwork and the dovetail groove of the insulation board (Fig. 1b), so that the concrete is formed in the building At the same time, it is integrated with the insulation board, so it is naturally integrated with the building.
