Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of assembled anti-punch prefabricated wall component. BACKGROUND

[0002] At present, the heat preservation of assembled prefabricated component is mainly through several mainstream ways such as the paste of thermal insulation after the thin plaster on the outside, the paste of thermal insulation after the thin plaster on the inside and prefabricated integrated sandwich thermal insulation. However, these methods all show obvious short board. The traditional external thermal insulation method needs to go through multiple processes during on-site construction, which leads to the extension of construction period, and there is the risk of cracking and falling in later period, which is contrary to the rapid and efficient goal pursued by building industrialization. Although the internal thermal insulation method is simple to operate, it will cause certain interference to indoor use function, such as easy to form cold bridge, leading to the occurrence of indoor condensation and mildew phenomenon. As for sandwich thermal insulation, the design of concrete protective layer on the outside is relatively thick, combined with the cold bridge effect after the edge treatment of thermal insulation material, which is easy to produce gap between thermal insulation layer and wall, which not only affects the overall stiffness distribution of component, but also may lead to the decline of thermal insulation performance. In addition, the production cost of sandwich thermal insulation prefabricated component is high, and the production cycle is long. Although the relevant departments actively promote its application, its application range is still limited in actual project.

[0003] In addition, the non-thermal insulation structure connecting piece used in the prior art also has adverse effects on the thermal insulation effect of energy-saving wall structure. These connecting pieces often fail to fully consider the thermal bridge effect on the thermal insulation effect during design and installation process, which leads to the heat transfer through connecting piece and reduces the overall thermal insulation performance of wall.

[0004] In view of the above problems, in order to meet the growing demand for building energy-saving and thermal insulation, it is particularly important to develop a new type of assembled integrated thermal insulation prefabricated component structure form which can realize efficient energy-saving and thermal insulation effect and perfectly integrate into assembled building system.

[0037] The following description of the embodiments is with reference to the accompanying drawings, which illustrate specific embodiments in which the present invention can be implemented.

[0038] like Figure 1 and Figure 2 As shown, this embodiment discloses a prefabricated wall component with reverse-layout construction. The prefabricated wall component with reverse-layout construction includes a base wall 1, a fireproof insulation board 2, and several connecting components 3. The fireproof insulation board 2 includes an insulation layer 21, which is made of insulation material with a fire resistance rating of Class A. The connecting components 3 include metal connectors and an insulation material layer. The insulation material layer covers the outer surface of the metal connectors, and both the metal connectors and the insulation material layer penetrate through the insulation layer 21 from one side, so that the connecting components 3 are exposed on the other side of the insulation layer 21. The base wall 1 includes wall reinforcement 12 and concrete 11. The wall reinforcement 12 is set on the other side of the insulation layer 21. The concrete 11 is poured on the wall reinforcement 12 and connected to the fireproof insulation board 2 and the connecting components 3, so that the fireproof insulation board 2 is connected to the base wall 1 using a reverse-layout process.

[0039] The wall reinforcement 12 is erected on the top surface of the fireproof insulation board 2, and then concrete 11 is poured on the wall reinforcement 12 to form the base wall 1, so that the base wall 1 is connected to the top surface of the fireproof insulation board 2. A reverse-laying process is used to connect the fireproof insulation board 2 to the base wall 1. The insulation layer 21 is made of fire-resistant material with a Class A fire rating, thus effectively providing fire protection and eliminating fire hazards. Simultaneously, several connecting components 3 connect the base wall 1 and the fireproof insulation board 2 together, thereby improving the connection's firmness, effectively preventing the fireproof insulation board 2 from falling, and greatly improving the safety and stability of the prefabricated reverse-laying wall components, meeting the application requirements of prefabricated buildings. Furthermore, the metal connectors are made of metal, ensuring a stable and reliable connection; the outer surface of the metal connectors is covered with an insulation material layer, which effectively enhances the thermal insulation effect of the prefabricated reverse-laying wall components, further overcoming thermal bridging. The structure is simple and easy to process and manufacture.

[0040] The concrete 11 can be lightweight concrete, wherein the material of the lightweight concrete is a cement-based material with bubble cavities and / or a cement-based material filled with lightweight aggregates. This makes the self-weight of the prefabricated wall component of the assembled counter-falling type light, effectively avoiding falling phenomenon, and greatly improving the safety and stability of the prefabricated wall component of the assembled counter-falling type. The concrete 11 can also be super-performance concrete. The use of super-performance concrete can effectively support the strength and ensure that the outer fireproof insulation board is not damaged during transportation and installation. The base wall 1 has a pre-embedded part. The pre-embedded part can be a wire box, a grouting sleeve, etc.

[0041] In the present embodiment, the thermal insulation layer 21 is an A-grade fireproof insulation material composed of a single homogeneous material. The A-grade fireproof insulation material effectively ensures the fireproof performance and thermal insulation performance of the prefabricated wall component of the assembled counter-falling type, so that there is no need to composite inorganic board to strengthen its strength and fireproof performance.

[0042] The material of the thermal insulation layer 21 can be polyurethane insulation material, and the material of the thermal insulation layer 21 can also be silicon graphene insulation material, which effectively ensures the thermal insulation performance and fireproof performance of the prefabricated wall component of the assembled counter-falling type, and greatly improves the safety and stability of the prefabricated wall component of the assembled counter-falling type.

[0043] The metal connecting piece includes an anchor disc 31 and an anchor rod 32. The anchor disc 31 abuts against one side of the thermal insulation layer 21 away from the base wall 1. One end of the anchor rod 32 is connected to the anchor disc 31, and the other end of the anchor rod 32 penetrates through the thermal insulation layer 21 and is connected to the base wall 1. An insulating material layer is wrapped on the outer surfaces of the anchor disc 31 and the anchor rod 32. The metal connecting piece abuts against the outer side of the thermal insulation layer 21 through the anchor disc 31, and connects the fireproof insulation board 2 to the base wall 1 through the anchor rod 32. The insulating material layer is wrapped on the outer surfaces of the anchor disc 31 and the anchor rod 32. The overall structure is simple and very convenient to use.

[0044] The outer surface of the connecting component 3 has outwardly protruding blocking structures 33. The outwardly protruding blocking structures 33 are located on the anchor rod 32 and the number is multiple. The multiple blocking structures 33 are tightly abutted against the fireproof insulation board 2 and the base wall 1, further strengthening the connection strength of the prefabricated wall component of the assembled counter-falling type, effectively preventing falling, and greatly improving the safety and stability of the prefabricated wall component of the assembled counter-falling type.

[0045] The fireproof insulation board 2 further comprises a reinforcing net 22, the reinforcing net 22 is embedded in the insulation layer 21 and / or is placed on the surface of the insulation layer 21, and the connecting component 3 penetrates the reinforcing net 22. In the process of processing, the reinforcing net 22 is placed above the raw material composition of the insulation layer 21 which is first laid in the mold, and then the second laying of the raw material composition of the insulation layer 21 is carried out in the mold, so that the raw material composition of the insulation layer 21 completely wraps the reinforcing net 22 after the second laying, and the reinforcing net 22 is embedded in the insulation layer 21. Of course, the reinforcing net 22 can also be arranged on the surface of the insulation layer 21 after the insulation layer 21 is processed. The reinforcing net 22 can further strengthen the overall structural strength of the prefabricated wall component, greatly improve the safety and stability of the prefabricated wall component, and meet the application requirements of prefabricated buildings.

[0046] In the embodiment, the connecting component 3 is connected to the reinforcing net 22, and the connecting component 3 penetrates the fireproof insulation board 2 through the anchor rod 32 and is connected to the reinforcing net 22, further strengthening the structural connection strength and greatly improving the safety and stability of the prefabricated wall component.

[0047] The connecting component 3 is connected to the wall body steel bar 12, and the connecting component 3 penetrates into the base wall 1 through the anchor rod 32 and is connected to the wall body steel bar 12, further strengthening the structural connection strength and greatly improving the safety and stability of the prefabricated wall component.

[0048] As shown in Figure 1 The top end of the fireproof insulation board 2 extends outward from the top surface of the base wall 1 and is exposed. The top end of the fireproof insulation board 2 and the top end of the base wall 1 are staggered in the height direction, the top end of the base wall 1 can be connected to the bottom surface of the floor, the fireproof insulation board 2 extends upward and can abut against the outer surface of the floor, that is, the inner side of the insulation layer 21 is connected to the floor to realize the overhanging of the top end.

[0049] The bottom end of the fireproof insulation board 2 is recessed inward from the bottom surface of the base wall 1. By recessing the bottom end of the fireproof insulation board 2 inward and staggering the bottom end of the fireproof insulation board 2 and the bottom end of the base wall 1 in the height direction, the grouting joint work of the base wall 1 can be checked; then the insulation layer is pasted, so that the structure of high outside and low inside effectively solves the leakage phenomenon caused by the existing gap, greatly improves the waterproof effect, and effectively solves the cold and hot bridge phenomenon caused by the existing gap.

[0050] The left and right end faces of the fireproof insulation board 2 are not in the same plane as the left and right end faces of the base layer wall body 1. The left and right end faces of the fireproof insulation board 2 can be extended outwardly to overhang or be recessed inwardly, so that the left and right assembled reverse-punching prefabricated wall bodies are designed to be staggered when spliced, effectively solving the leakage problem caused by the existing gaps, greatly improving the waterproof effect of the assembled reverse-punching prefabricated wall bodies, and effectively solving the cold and hot bridge phenomenon caused by the existing gaps.

[0051] The assembled reverse-punching prefabricated wall body further comprises a finishing layer, which can be connected to the side of the thermal insulation layer 21 away from the base layer wall body 1, or to the side of the base layer wall body 1 away from the fireproof insulation board 2. The finishing layer has a reinforcing protection effect, ensuring good use function of the assembled reverse-punching prefabricated wall body.

[0052] The finishing layer comprises mortar and mesh cloth, the mortar is connected to the side of the thermal insulation layer 21 away from the base layer wall body 1 and / or the side of the base layer wall body 1 away from the fireproof insulation board 2, and the mesh cloth is arranged in the mortar. The mesh cloth arranged in the mortar can enhance the overall structural firmness of the finishing layer, and the mortar is used for leveling protection. Preferably, the mortar is a polymer anti-cracking mortar.

[0053] The assembled reverse-punching prefabricated wall body further comprises a finishing layer, which can be connected to the side of the thermal insulation layer 21 away from the base layer wall body 1, or to the side of the base layer wall body 1 away from the fireproof insulation board 2. The finishing layer has a reinforcing protection effect, ensuring good use function of the assembled reverse-punching prefabricated wall body.
