Description

Technical Field

[0001] The utility model belongs to the technical field of building exterior wall thermal insulation, and particularly relates to a wire mesh combined thermal insulation board for a cast-in-place concrete self-thermal insulation wall. Background Technique

[0002] The wire mesh combined thermal insulation board is a three-dimensional space grid thermal insulation board formed by combining a galvanized wire mesh that plays a structural role with a thermal insulation board through a limit fixing part, which is simply called a mesh combined thermal insulation board. According to different uses, it is divided into a single-sided mesh combined thermal insulation board and a double-sided mesh combined thermal insulation board. When in use, concrete is poured on both sides of the wire mesh combined thermal insulation board at the same time to form a self-thermal insulation wall. Among them, the single-sided mesh combined thermal insulation board is used for the self-thermal insulation wall of shear walls, and the double-sided mesh combined thermal insulation board is used for the self-thermal insulation wall of infill walls.

[0003] When pouring concrete for the wire mesh combined thermal insulation board cast-in-place concrete wall thermal insulation system, it is necessary to pour concrete on both sides of the thermal insulation board at the same time. When pouring at the same time, when the pouring on one side is slow, stuck, or the consistency of the slurry is different, it will cause the concrete on the other side to push the thermal insulation board to move towards the side with slow pouring, and then cause deviation of the formwork and bulging of the formwork, affecting the thermal insulation performance and mechanical properties of the wall.

[0004] To solve the above problems, a Chinese utility model (application number: 201820499932.9, name: A composite wall of a cast-in-place concrete steel wire grid thermal insulation system) provides an idea, that is, diversion grooves are provided on the thermal insulation board, which can enable the concrete to flow through between the thermal insulation boards.

[0005] Although this method enables the concrete to flow through between the thermal insulation boards, since the angle between the diversion groove and the thermal insulation board is an acute angle, therefore, on both sides of the diversion groove on the thermal insulation board, one side is high and the other side is low. Therefore, when feeding materials on both sides of the thermal insulation board at the same time, when the height of the concrete is lower than the higher side of the diversion groove, the concrete cannot pass through the diversion groove, so the same phenomenon that the concrete on the other side pushes the thermal insulation board to move towards the side with slow pouring will occur, and then cause deviation of the formwork and bulging of the formwork, affecting the thermal insulation performance and mechanical properties of the wall. Content of the Utility Model

[0006] The utility model provides a wire mesh combined thermal insulation board for a cast-in-place concrete self-thermal insulation wall, which is used to solve defects such as deviation of the formwork and bulging of the formwork caused by the movement of the thermal insulation board body to one side under the push of concrete.

[0007] The utility model is realized through the following technical solutions:

[0008] A steel wire mesh combined thermal insulation board for a cast-in-place concrete self-thermal insulation wall, comprising a thermal insulation board body and a steel wire mesh combined on the outer side of the thermal insulation board body. The combined thermal insulation board is vertically arranged in a concrete cavity. A plurality of circular through holes are formed in the thermal insulation board body, and the circular through holes penetrate along the thickness direction of the thermal insulation board body. The axis line of the circular through hole is perpendicular to the side surface of the thermal insulation board body, and the concrete cavity is penetrated through the circular through hole.

[0009] The utility model can ensure that when concrete is poured on both sides of the thermal insulation board body in the concrete cavity at the same time, when there are problems such as slow pouring or jamming of the concrete on one side, as long as the concrete crosses the circular through hole on that side, the extra concrete on one side will enter the other side of the thermal insulation board body along the circular through hole, realizing the penetration of the circular through hole. Thus, it can ensure that the concrete on both sides of the thermal insulation board body is basically at the same height, prevent the thermal insulation board body from moving to one side under the push of the concrete and causing side form deviation or form bulging, ensure that the thermal insulation board body is on the same vertical plane of the wall, and realize the thermal insulation performance and mechanical performance of the wall. At the same time, the concrete passes through the circular through hole to connect the inside and outside into one body, making the cast-in-place concrete self-thermal insulation wall safer and more firm.

[0010] Preferably, steel wire meshes are fixedly arranged on both sides of the thermal insulation board body. The thermal insulation board body and the steel wire meshes are arranged in the concrete cavity, so that steel wire mesh reinforced concrete structural layers are formed on both sides of the thermal insulation board body. This structure is applicable to the self-thermal insulation wall of a filling wall.

[0011] Preferably, the steel wire mesh and the thermal insulation board body are fixedly connected through a first connecting member. The first connecting member includes a first base fixedly arranged on the steel wire mesh. The two first bases are fixedly connected through a first limiting rod vertically penetrating the thermal insulation board body and the concrete cavity. Two first positioning pieces are arranged on the first limiting rod. The thermal insulation board body is arranged between the two first positioning pieces and the corresponding side surfaces are attached to the first positioning pieces. The fixed connection between the steel wire mesh and the thermal insulation board body can be realized through the first connecting member.

[0012] Preferably, a steel reinforcement cage is fixedly arranged on the inner side of the thermal insulation board body. The steel reinforcement cage and the steel wire mesh are both arranged in the concrete cavity. Thus, on one side of the thermal insulation board body is a steel wire mesh reinforced concrete layer, and on the other side is formed a concrete shear wall. This structure is applicable to the self-thermal insulation wall of a shear wall.

[0013] Preferably, the steel wire mesh, the thermal insulation board body and the steel reinforcement cage are fixedly connected through a second connecting member. The second connecting member includes second bases fixedly arranged on the steel wire mesh and the steel reinforcement cage. The second bases are fixedly connected through a second limiting rod vertically penetrating the thermal insulation board body and the concrete cavity. Two second positioning pieces are arranged on the second limiting rod. The thermal insulation board body is arranged between the two second positioning pieces and the corresponding side surfaces are attached to the second positioning pieces. Thus, the fixed connection among the steel wire mesh, the thermal insulation board body and the steel reinforcement cage can be realized through the second connecting member.

[0014] Preferably, the circular through-holes are distributed in a rectangular array on the heat-insulating board body, and 4 to 10 circular through-holes are arranged per square meter. This can ensure that under the premise of meeting the structural strength of the heat-insulating board body, the concrete can penetrate into the other side more quickly through the circular through-holes, further preventing the heat-insulating board from shifting.

[0015] Preferably, the distance between the circular through-holes and the edge of the heat-insulating board body is not less than 50 mm, which can effectively increase the strength of the heat-insulating board body.

[0016] Preferably, the diameter of the circular through-holes is 20 mm to 50 mm.

[0017] The beneficial effects of the present utility model are as follows: When pouring concrete on both sides simultaneously, as long as the concrete crosses the circular through-holes during pouring, when the pouring of the concrete on one side is slow or stuck, the extra concrete on the other side will enter the corresponding side of the heat-insulating board body along the circular through-holes. Thus, it can ensure that the concrete on both sides of the wire mesh combined heat-insulating board body is basically at the same height, preventing the heat-insulating board body from moving to one side under the push of the concrete and causing side form deviation or bulge form, ensuring that the heat-insulating board body is on the same vertical plane of the wall, and realizing the heat insulation performance and mechanical properties of the wall. At the same time, the concrete passes through the circular through-holes to connect the inside and outside into one body, and the cast-in-place concrete self-insulating wall is safer and more firm.

[0028] Embodiment 1:

[0029] A steel wire mesh combined insulation board for a cast-in-place concrete self-insulation wall, as Figures 1 to 3 shown. It includes an insulation board body 1 and steel wire meshes 4 vertically arranged on both sides of the insulation board body 1. The combined insulation board composed of the insulation board body 1 and the steel wire meshes 4 is arranged in a concrete cavity, where the concrete cavity is a cavity formed between two outer templates for accommodating and shaping the concrete 3. A plurality of circular through-holes 2 are formed in the insulation board body 1. The circular through-holes 2 penetrate along the thickness direction of the insulation board body 1, and the axis of the circular through-hole 2 is perpendicular to the side surface of the insulation board body 1. The concrete cavity penetrates through the circular through-holes 2.

[0030] Among them, in this embodiment, the insulation board body 1 and the steel wire meshes 4 on both sides are arranged in the concrete cavity, so that steel wire mesh 4 reinforced concrete structural layers are formed on both sides of the insulation board body 1. This structure is applicable to the self-insulation wall of the filling wall.

[0031] In this embodiment, when pouring concrete 3 into the concrete cavity, the concrete 3 is poured synchronously on both sides of the insulation board body 1. When there are problems such as slow pouring or jamming on one side of the concrete 3 and the concrete 3 crosses the circular through-hole 2, the extra concrete 3 on the other side will enter the corresponding side of the insulation board body 1 along the circular through-hole 2, so as to ensure that the concrete 3 on both sides of the insulation board body 1 is basically at the same height, prevent the insulation board body 1 from moving to one side under the push of the concrete 3 and causing side form deviation or bulge form, ensure that the insulation board body 1 is on the same vertical plane of the wall, and realize the heat preservation performance and mechanical performance of the wall. At the same time, the concrete 3 passes through the circular through-hole 2 to connect the inside and outside into one body, and the cast-in-place concrete 3 self-insulating wall is safer and more firm.

[0032] The wire mesh sheet 4 and the insulation board body 1 are fixedly connected through the first connecting member 6. The first connecting member 6 includes a first base 61 fixedly arranged on the wire mesh sheet 4. The two first bases 61 are fixedly connected through a first limiting rod 62.

Through the first connecting member 6, the fixed connection between the wire mesh sheet 4 and the insulation board body 1 can be realized.

[0033] The circular through-holes 2 are distributed in a rectangular array on the insulation board body 1 and 4 to 10 are arranged per square meter. It can ensure that on the premise of meeting the structural strength of the insulation board body 1, the concrete 3 can penetrate into the other side more quickly through the circular through-holes 2, and further prevent the insulation board from shifting.

[0034] The distance between the circular through-hole 2 and the edge of the insulation board body 1 is not less than 50 mm, which can effectively increase the strength of the insulation board body 1, and the diameter of the circular through-hole 2 is 20 mm to 50 mm.

[0035] The utility model can ensure that when pouring concrete 3 on both sides at the same time, when there is slow pouring or jamming on one side of the concrete 3, as long as the pouring height of the concrete 3 has crossed the circular through-hole 2, the extra concrete 3 on the other side will enter the other side of the insulation board body 1 along the circular through-hole 2, realizing the penetration of the concrete cavities on both sides of the insulation board body 1, so as to ensure that the concrete 3 on both sides of the wire mesh sheet 4 combined with the insulation board body 1 is basically at the same height, prevent the insulation board body 1 from moving to one side under the push of the concrete 3 and causing side form deviation or bulge form, ensure that the insulation board body 1 is on the same vertical plane of the wall, realize the heat preservation performance and mechanical performance of the wall. At the same time, the concrete 3 passes through the circular through-hole 2 to connect the inside and outside into one body, and the cast-in-place concrete 3 self-insulating wall is safer and more firm.

[0038] , compared with Embodiment 1, a wire mesh sheet 4 is arranged on the outer side of the insulation board body 1, and a steel reinforcement cage is fixedly arranged on the inner side of the insulation board body 1. Both the steel reinforcement cage and the wire mesh sheet 4 are arranged in the concrete cavity and are completely covered by the concrete.

[0038] During the use of this embodiment, both the steel reinforcement cage and the wire mesh sheet 4 are arranged in the concrete cavity. Thus, one side of the insulation board body 1 is a concrete layer reinforced by the wire mesh sheet, and the other side forms a concrete shear wall. This structure is applicable to the self-insulating wall of the shear wall.

[0039] The wire mesh sheet 4, the insulation board body 1 and the steel reinforcement cage are fixedly connected through a second connecting member 7. The second connecting member 7 includes second bases 71 fixedly arranged on the wire mesh sheet 4 and the steel reinforcement cage. The second bases 71 are fixedly connected through a second limiting rod 72. The second limiting rod 72 vertically penetrates the insulation board body 1 and the concrete cavity. Two second positioning pieces 73 are arranged on the second limiting rod 72. The insulation board body 1 is arranged between the two second positioning pieces 73 and the corresponding side surfaces are attached to the second positioning pieces 73. Thus, the fixed connection between the wire mesh sheet 4, the insulation board body 1 and the steel reinforcement cage can be realized through the second connecting member 7.
