Description

Technical Field

[0001] The present application relates to the field of thermal insulation floor slab construction, and in particular to a thermal insulation integrated board and a thermal insulation wall construction method. Background Art

[0002] In construction, in order to improve the thermal insulation performance of the building, it is usually necessary to add an insulation layer at the boundary between the heated and non-heated rooms to isolate the heat transfer between the two rooms through the insulation layer, ensure that the heated room maintains a higher temperature, and ensure that the non-heated room maintains the handover temperature.

[0003] At present, the traditional insulation layer construction method is to stick a layer of insulation board on the bottom of the structural floor after the construction is completed. This method requires secondary construction. During the secondary construction, the insulation board needs to be fixed to the structural floor. The insulation board needs to be fixed after the structural floor is completely solidified. This not only increases the construction time at the construction site, but also increases the workload at the construction site.

[0004] Therefore, how to reduce the construction time at the construction site and reduce the workload at the construction site are issues that need to be urgently addressed. Summary of the invention

[0005] In order to reduce the workload at the construction site, the present application provides a thermal insulation integrated panel and a thermal insulation floor slab and a construction method of the floor slab.

[0006] In the first aspect, the present application provides a thermal insulation integrated panel, which adopts the following technical solution: A thermal insulation integrated board, comprising: An inner core, wherein the inner core comprises a plurality of polystyrene boards, the board surfaces of the polystyrene boards are perpendicular to the first direction X, the plurality of polystyrene boards are spaced apart along the second direction Y, a casting gap is formed between two adjacent polystyrene boards in the second direction Y, and the casting gap is filled with an embedded mortar layer; It also includes an outer mortar layer, and the outer periphery of the inner core is coated with the outer mortar layer.

[0007] By adopting the above technical scheme, the polystyrene board can play a thermal insulation effect. Since the polystyrene board is coated with an outer mortar layer, concrete can be poured directly on the outer mortar layer, and the concrete can be firmly bonded to the outer mortar layer to form a floor slab, that is, the thermal insulation integrated board can be used directly as the bottom supporting formwork. After the thermal insulation integrated board is bonded and fixed to the poured concrete, there is no need to remove it, that is, there is no need to perform demolding operations. Therefore, the construction time at the construction site can be reduced.

[0008] Optionally, it also includes steel bars embedded in the embedded mortar layer, and the steel bars are arranged parallel to the third direction Z.

[0009] By adopting the above technical solution and embedding steel bars in the inner cavity mortar layer, the overall mechanical properties of the thermal insulation integrated panel can be improved.

[0010] Optionally, a glass fiber mesh is embedded in the outer mortar layer, and each surface of the inner core is parallel to the glass fiber mesh outside the surface.

[0011] By adopting the above technical solution, the fiberglass mesh can effectively prevent the outer mortar layer from cracking and can improve the mechanical properties of the thermal insulation integrated board.

[0012] Optionally, the glass fiber mesh is provided with two layers.

[0013] By adopting the above technical solution, the outer mortar layer can be further prevented from cracking.

[0014] Optionally, a reinforcement component is also included, and the reinforcement component includes: A first reinforcement ring, wherein the first reinforcement ring is embedded in the inner core and sleeved on the steel bar; a first reinforcement sleeve, wherein one end of the first reinforcement sleeve is fixedly connected to the first reinforcement ring, and the other end of the first reinforcement sleeve extends through the inner core and the outer mortar layer to be flush with the board surface of the outer mortar layer; the board surface of the outer mortar layer that is flush with the first reinforcement sleeve is the first board surface, and the other board surface is the second board surface; and A telescopic rod, one end of which is detachably connected to the first reinforcement sleeve.

[0015] By adopting the above technical solution, concrete is poured onto the first board surface wrapped with the mortar layer, and the telescopic rod will be buried in the concrete, so that an anchoring state is formed between the telescopic rod and the solidified concrete. The adjustable length feature of the telescopic rod can adjust the telescopic rod to the required length to adapt to different anchoring depths, thereby improving the firmness of the connection between the thermal insulation integrated board and the post-cast concrete.

[0016] Optionally, a collusion component is also included, and the collusion component includes: A rotating seat, the rotating seat being fixedly connected to an end of the telescopic rod away from the steel bar; Two connecting rods, the two connecting rods are cross-arranged in an X shape, and the intersection of the two connecting rods is rotatably connected to the rotating seat, and the connecting rods are perpendicular to the first direction X along the rotation axis of the rotating seat; and A tension spring is located at one end of the intersection of the two connecting rods away from the steel bars, and both ends of the tension spring are respectively fixedly connected to one of the connecting rods.

[0017] By adopting the above technical solution, the hooking assembly can be installed on part or all of the telescopic rods according to actual needs. The cross-arranged connecting rods can generate greater anchoring force between the post-poured concrete to further improve the firmness of the connection between the thermal insulation integrated panel and the post-poured concrete.

[0018] Optionally, the end of the connecting rod forms an outer flange toward the side away from the reference line, and the outer periphery of the outer flange is arc-shaped; the reference line is perpendicular to the plate surface of the inner core, and the reference line forms a cross state at the intersection of the two connecting rods.

[0019] By adopting the above technical solution, before pouring concrete on the thermal insulation integrated board, a steel cage can be placed on the thermal insulation integrated board first, and then the connecting rod can be rotated to the outer edge to hook it to the steel cage, so that the thermal insulation integrated board is connected to the steel cage through the hooking component. After the subsequent pouring of concrete, the firmness of the connection between the thermal insulation integrated board and the post-cast concrete layer can be improved.

[0020] Optionally, a mounting assembly is further included, and the mounting assembly includes: a second reinforcement ring, wherein the second reinforcement ring is embedded in the inner core and sleeved on the steel bar; and A second reinforcement sleeve, one end of which is fixedly connected to the second reinforcement ring, and the other end of which extends to be flush with the second plate surface of the inner core; A hook, the hook being detachably connected to the second reinforcement sleeve; The first reinforcement ring and the second reinforcement ring form a separation gap in a direction parallel to the steel bar.

[0021] By adopting the above technical solution, after the thermal insulation integrated board and the post-cast concrete form a floor slab, the hook can be installed on the second reinforcement sleeve, and the hook can be used to hang subsequent structures such as air ducts; because the hanging assembly is installed on the steel bar, and the steel bar can be connected to the steel cage in the post-cast concrete through the hook assembly, it forms an integrated bearing structure, providing a more solid installation foundation for the subsequent installation of the air duct. In addition, since there is a gap between the first reinforcement ring and the second reinforcement ring, it can avoid the thermal insulation integrated board from forming a through hole in the first direction X, so as to ensure the thermal insulation effect of the thermal insulation integrated board.

[0022] In a second aspect, the present application provides a thermal insulation floor slab, which adopts the following technical solution: An insulation floor slab, comprising the aforementioned insulation integrated slab, and further comprising a concrete layer and a steel mesh; In the first direction X, the concrete layer is sandwiched between two layers of the thermal insulation integrated panels; The steel mesh is buried in the concrete layer.

[0023] By adopting the above technical solution, concrete is cast between two layers of thermal insulation integrated panels, so that the outer mortar layer of the outer layer of the thermal insulation integrated panel can be better bonded with the concrete. At the same time, the thermal insulation integrated panel can be used as a template. After the concrete is removed, there is no need to install the thermal insulation panel later, which shortens the construction period at the construction site.

[0024] In a third aspect, the present application provides a floor construction method using the following technical solution: A thermal insulation floor construction method comprises the following steps: S1: Build the formwork support frame; S2: Laying a layer of thermal insulation integrated board at the bottom layer on the formwork support frame, and arranging a circle of thermal insulation integrated boards placed vertically around the thermal insulation integrated board to form a concrete casting mold cavity, and the second board surface is located on a side of the thermal insulation integrated board away from the concrete casting mold cavity; S3: pouring concrete into the concrete pouring mold cavity; S4: Laying an upper layer of thermal insulation integrated board on the concrete in the concrete casting mold cavity; S5: Cure the concrete and remove the formwork support frame after the concrete has finally set.

[0025] By adopting the above technical solution, the formwork is replaced by the thermal insulation integrated board. After the concrete is removed, there is no need to remove the formwork or install the thermal insulation board, which shortens the construction period at the construction site.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. This application uses the thermal insulation integrated board directly as the bottom support formwork. After the thermal insulation integrated board is bonded and fixed to the poured concrete, it does not need to be removed, that is, there is no need to perform formwork removal operations, thus reducing the construction time at the construction site; 2. The fastening components can improve the firmness between the thermal insulation integrated board and the post-cast concrete; 3. The subsequent installation of air ducts is facilitated by the hanging assembly, and because the gravity of the air duct is borne jointly by the hanging assembly, steel bars, hooking assembly and steel cage, there is no need to drill additional holes in the floor slab when hoisting the air duct subsequently, thus ensuring the thermal insulation effect of the floor slab. The bearing foundation formed by multiple structures can provide a solid installation foundation for the air duct. BRIEF DESCRIPTION OF THE DRAWINGS
