DETAILED DESCRIPTION

[0041] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] Example 1

[0043] like Figure 1~Figure 2 As shown, this embodiment proposes a composite insulation board with a non-removable formwork mesh, including an insulation board 1, a connecting piece 2 passed through the insulation board 1, a non-removable formwork mesh 3 arranged outside the connecting piece 2, the non-removable formwork mesh 3 and the insulation board 1 have a separation space 6, the separation space 6 is used for pouring concrete, and the non-removable formwork mesh 3 has a plurality of arrays of mesh holes 301.

[0044] In this embodiment, considering that the prior art uses cast-in-place concrete built-in insulation board 1, one or both sides need to be poured with concrete. The cast concrete as a filling wall has a large rigidity, which affects the safety of the building structure. The secondary structure casting concrete construction is difficult, and the on-site formwork and demolding construction costs are high. In order to solve this problem, this application develops a low-cost, easy-to-construct, structurally safe, mold-free composite insulation board, which is applied to frame structures, shear wall structures, steel structure cast-in-place systems, and frame structures and steel structure assembled lightweight wall panels. The insulation board 1 is the main insulation component, and the connector 2 is inserted on the insulation board 1 as a support body of the insulation board. The connector 2 is made of stainless steel, and its thermal conductivity is 2 / 3 lower than that of traditional threaded steel, which greatly improves the thermal performance of the composite insulation board. The non-disassembly formwork net 3 is arranged on the connecting piece 2, and has a spacing space 6 with the insulation board 1, and the spacing space 6 is used for pouring concrete. The non-disassembly formwork net 3 has a plurality of arrays of mesh holes 301, and the mesh holes can keep the lightweight concrete in the spacing space 6 after pouring. The mesh holes serve as a mold for lightweight concrete, thereby eliminating the process of on-site formwork and demolding, thereby reducing construction costs. The composite insulation board with the non-disassembly formwork net can be applied to load-bearing parts to eliminate the need for a formwork on one side, and can be applied to non-load-bearing walls to eliminate the need for both sides. The composite insulation board with the non-disassembly formwork net can be directly installed on the construction site, and concrete can be poured after pre-buried pipelines.

[0045] The mold-free mesh composite insulation board in this embodiment does not need to be sprayed with mortar on the outside, so it can solve the problem of cracking in the later stage of spraying mortar on both sides. Lightweight concrete is used as the internal decorative wall, and the wall hoisting heavy objects does not have the problem of alkali return; the materials used in the construction do not produce formaldehyde and will not pollute the indoor environment; there is no fibrous ceramic wool, which is friendly to the construction workers, and there is no problem of water absorption caused by cracking on the outside. As a non-load-bearing wall formwork, it is filled with lightweight concrete, which does not affect the safety of the building structure, and can meet the mechanical performance indicators, and the structural force system is clear. The construction is convenient and the construction cost is reduced.

[0046] Furthermore, the mesh 301 is circular or polygonal, and the hole area of ​​the mesh 301 is 1 to 100 square millimeters.

[0047] In this embodiment, the mesh of the mold-free mesh composite insulation board is rectangular or parallelogram, and the size is 1~3mm*6~8mm. The rectangle or parallelogram is set to facilitate processing and reduce costs. The size is 1~3mm*6~8mm to ensure that the concrete can remain stable in the spacing space 6 and will not overflow through the mesh 301.

[0048] In this embodiment, the mesh area of ​​the formwork-free mesh composite insulation board is 1-100 square millimeters, which is smaller than the range of light concrete overflow to ensure that the formwork-free mesh composite insulation board can be used as a template.

[0049] Furthermore, it also includes a first steel mesh 4, a connecting piece 2 connected to the first steel mesh 4, and the non-disassembly template mesh 3 is arranged side by side with the first steel mesh 4 and is located on a side of the non-disassembly template mesh 3 close to the insulation board 1 or a side away from the insulation board 1.

[0050] In this embodiment, the first steel mesh 4 is arranged on the connector 2 as a support for the side of the connector 2, so that the insulation board 1, the connector 2, and the first steel mesh 4 are connected as a whole, thereby improving the stability of the overall structure. The non-disassembly formwork mesh 3 is arranged on the first steel mesh 4, and the first steel mesh 4 serves as a vertical support for the non-disassembly formwork mesh 3; the mesh is arranged on one side of the non-disassembly formwork mesh 3, that is, both sides, in order to further ensure that the concrete will not leak out. The non-disassembly formwork mesh 3 can be arranged on the side close to the insulation board 1, or on the side away from the insulation board 1, so that the poured concrete can be well blocked and not exposed.

[0051] Furthermore, the connecting member 2 is rod-shaped, and has a bent portion 200 at the end, and the bent portion 200 is hooked on the first steel mesh 4 .

[0052] In this embodiment, the connecting member 2 can be designed to be rod-shaped and have bending portions 200 at both ends, which can be hooked on the first steel mesh 4 and can also provide inner pulling force to prevent the first steel mesh 4 and the non-disassembly formwork mesh 3 from being stretched open and falling down by the poured concrete, thereby avoiding the occurrence of construction failure.

[0054] like Figure 3 As shown, it includes all the structures of Example 1, and further includes a second steel mesh 7, which is located between the insulation board 1 and the non-removal formwork mesh 3, and between the insulation board 1 and the first steel mesh 4. In this embodiment, the second steel mesh 7 is also designed to be located between the insulation board 1 and the non-removal formwork mesh 3, and also between the insulation board 1 and the first steel mesh 4, which can further increase the applicability of the product, so that when pouring ceramsite foam concrete, the design of the second steel mesh 7 can also achieve sufficient structural strength.

[0057] In this embodiment, the connecting member 2 can also be designed to be a steel truss or an oblique inserted reinforcement or an L-shaped reinforcement or a Z-shaped reinforcement or a U-shaped reinforcement or a Y-shaped reinforcement. A variety of structures can achieve a better connection effect, further ensuring that the first steel mesh 4 and the non-disassembly formwork mesh 3 are well connected, and further preventing the first steel mesh 4 and the non-disassembly formwork mesh 3 from being stretched apart and falling down by the poured concrete.

[0058] In this embodiment, both sides of the insulation board 1 are provided with a non-removal formwork mesh 3, which is suitable for cast-in-place non-weight-bearing shear wall structure, frame structure, and steel structure. The non-removal formwork mesh 3 on both sides can be used as a lightweight concrete formwork. The connecting parts 2 have several layers, and the two adjacent layers of connecting parts 2 are staggered to improve the overall mechanical properties of the non-removal formwork mesh composite insulation board.

[0060] In this embodiment, the binding wire is tied to the first steel mesh 4 and the non-disassembly formwork mesh 3, which can play a more stable connection role and prevent the first steel mesh 4 and the non-disassembly formwork mesh 3 from being separated. One end of the pad 5 is supported on the insulation board 1, and the other end is set on the first steel mesh 4. The pad 5 is used to fix the position of the insulation board 1 to ensure that the relative position of the insulation board 1 and the first steel mesh 4 will not change. The binding wire is tied to the first steel mesh 4 and the non-disassembly formwork mesh 3, so that the first steel mesh 4 and the non-disassembly formwork mesh 3 are fixed more stably.

[0061] Furthermore, the cushion block 5 has a support surface 501 at one end and a plurality of L-shaped slots 502 at the other end, and the first steel mesh 4 passes through the L-shaped slots 502 .
