Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a structural component connection system for prefabricated lightweight concrete insulation panels. Background Technology

[0002] In existing prefabricated buildings, to improve the thermal insulation performance of the building walls, precast lightweight concrete insulation boards are typically installed on the exterior walls. These boards mainly consist of a precast lightweight concrete layer, steel mesh and rigid units embedded within the precast layer, and anchor cables connecting to the cast-in-place exterior wall layer. The rigid units support the entire precast layer, ensuring sufficient rigidity to prevent breakage during transportation and handling. These rigid units can be truss reinforcement bars or steel profiles, fiberglass reinforced plastics, etc., embedded within the precast layer. Anchor cables connect the insulation board to the cast-in-place exterior wall layer to prevent the insulation board from falling after long-term use.

[0003] In the production of precast lightweight concrete insulation boards, it is typically necessary to use spacers to place the reinforcing mesh inside the mold, then tie rigid units to the reinforcing mesh, connect anchor cables to the reinforcing mesh or rigid units, and finally pour lightweight concrete to form the precast insulation board. This connection structure results in numerous production steps, complex connections between various structural components, and all operations are manual, making it easy to overlook connection points, thus making quality control difficult. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the production of precast lightweight concrete insulation boards in the prior art has problems such as complex connections between various structural components, many processes, and difficulty in quality control. The present invention provides a structural component connection system for precast lightweight concrete insulation boards, which makes the connection of structural components during production and construction more convenient and faster.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a structural component connection system for a precast lightweight concrete insulation board is constructed, including a steel mesh, a pad block disposed on the bottom side of the steel mesh, and a rigid unit disposed on the top side of the steel mesh. It also includes a special binding strap that connects the steel mesh, the pad block, and the rigid unit together. The special binding strap includes a flexible clip with a free end and a connecting end, and a positioning frame disposed on the connecting end of the flexible clip. The positioning frame has a positioning slot through which the free end of the flexible clip passes. Matching clips and teeth are provided between the positioning slot and the side of the flexible clip.

[0006] Furthermore, the free end of the flexible tape passes through the rigid unit, the reinforcing mesh, and the pad, then loops back to the positioning frame and passes through the positioning slot, thereby reliably fixing the rigid unit, the reinforcing mesh, and the pad together.

[0007] Furthermore, the positioning slot includes a first positioning slot on the positioning frame near the connecting end of the special binding strap, and a second positioning slot on the positioning frame parallel to the first positioning slot. During production, the flexible strap of the special binding strap passes through the first positioning slot to bind and connect the structural components together. During construction, the flexible strap of the same special binding strap passes through the second positioning slot to connect with the steel mesh in the cast-in-place layer of the exterior wall. This allows a single special binding strap to connect the structural components of the insulation board together and reliably connect the entire insulation board to the exterior wall.

[0008] Furthermore, the free end of the flexible card passes through the rigid unit, the steel mesh, and the pad, then loops back to the positioning frame and passes through the first positioning slot.

[0009] Furthermore, the free end of the flexible card passes through the first positioning slot, then around the steel mesh in the cast-in-place layer of the outer wall, and then passes through the second positioning slot.

[0010] Furthermore, the pad has a connecting through hole that matches the flexible strap of the special binding strap. The free end of the flexible strap passes through the connecting through hole of the pad and then loops back to the positioning frame so as to position the pad on the flexible strap. The free end of the flexible strap passes through the rigid unit and the steel mesh and loops back to the positioning frame.

[0011] Furthermore, the pad has a groove on its side facing the reinforcing mesh that matches the reinforcing mesh, so that the pad is positioned on the bottom side of the reinforcing mesh.

[0012] Furthermore, the flexible card tape has teeth on both sides, so that the flexible card tape can be inserted into the positioning slot from different directions according to the actual situation.

[0013] The structural component connection system of the precast lightweight concrete insulation board of this utility model has the following beneficial effects: By setting a special binding strap including a flexible strap and a positioning frame, and setting a positioning slot in the positioning frame for the free end of the flexible strap to pass through, the flexible strap passes through the rigid unit, the steel mesh and the spacer, and then loops back to the positioning frame and passes through the positioning slot, thereby binding the rigid unit, the steel mesh and the spacer together at one time. The process is simpler, the operation is simpler for workers, and the production is more efficient. At the same time, it reduces the use of various specifications of binding wire or strap, and reduces the cost of procurement and storage. By setting matching blocks and teeth on the side of the flexible strap in the slot, the flexible strap can be positioned in the positioning slot, so that the flexible strap can tightly bind the rigid unit, the steel mesh and the spacer together, and the connection between the various structural components is more compact and reliable.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] like Figure 1 , 1aAs shown in Figures 2, 3, 3a, 4, and 5, in a preferred embodiment of the structural component connection system for the precast lightweight concrete insulation board of this utility model, the system mainly includes a reinforcing mesh 1, a pad 2, a rigid unit 3, and a special binding strap 10. The pad 2 is disposed on the bottom side of the reinforcing mesh 1, and the rigid unit 3 is disposed on the top side of the reinforcing mesh 1. The special binding strap 10 includes a flexible strap 11 and a positioning frame 12. The positioning frame 12 has a positioning groove 13. The flexible strap 11 includes a free end 11a and a connecting end 11b. The connecting end 11b is connected to the positioning frame 12, and the free end 11a passes through the positioning groove 13. A locking block 14 and a locking tooth 15 are provided between the positioning groove 13 and the flexible strap 11 to cooperate with each other. Specifically, the tooth 15 can be set on the side of the flexible card tape 11, and the block 14 can be set on the groove wall of the positioning slot 13. When the free end 11a of the flexible card tape passes through the positioning slot 13, the block 14 can restrict the tooth 15 to slide in one direction, thereby limiting the flexible card tape 11 in the positioning slot 13.

[0024] like Figure 1 , 1a As shown in Figure 2, when producing precast lightweight concrete insulation boards in a factory, structural components are first pre-set in the mold, and then lightweight concrete is poured into the mold. In this preferred embodiment, it is preferable to first connect the structural components together using a structural component connection system, and then simultaneously place all the connected structural components (such as steel mesh 1, rigid unit 3, spacer 2, etc.) into the mold. Specifically, special binding straps 10 are set on the steel mesh according to a preset density. Each special binding strap 10 passes around the rigid unit 3, steel mesh 1, and spacer 2 and then returns to the positioning frame 12 located above the rigid unit. The free end 11a of the flexible strap of the special binding strap passes through the positioning slot 13 of the positioning frame, thereby binding the rigid unit 3, steel mesh 1, and spacer 2 together, so that the rigid unit 3 is fixed on the top side of the steel mesh 1 and the spacer 2 is positioned on the bottom side of the steel mesh 1, and the spacer 2 is located exactly below the rigid unit 3.

[0025] like Figure 3a , 4As shown, in a preferred embodiment of the structural component connection system of the precast lightweight concrete insulation board of this utility model, the positioning slot 13 within the positioning frame preferably includes a first positioning slot 13a and a second positioning slot 13b. The first positioning slot 13a is located on the positioning frame 12 near the flexible strap connection end 11b of the special binding strap, while the second positioning slot 13b is located on the positioning frame 12 parallel to the first positioning slot 13a. That is, the first positioning slot 13a is closer to the connection end 11b of the flexible strap than the second positioning slot 13b. Preferably, the free end 11a of the flexible strap passes through the rigid unit, the reinforcing mesh, and the pad, and then loops back to the positioning frame, passing through the first positioning slot 13a. Since the first positioning slot is closer to the connection end of the flexible strap, after the free end of the flexible strap passes through the first positioning slot, the flexible strap is shorter than the flexible strap required for the second positioning slot when passing through the positioning frame located on the top side of the rigid unit, and the flexible strap is closer to the outer contour of the rigid unit, resulting in a more compact relationship between the rigid unit and the reinforcing mesh. The remaining portion of the free end of the flexible card passes through the second positioning slot 13b to form a closed loop 16 on the side of the positioning frame, which is connected to the steel mesh of the cast-in-place outer wall layer.

[0026] like Figure 2 As shown, after the precast lightweight concrete insulation board is formed in the factory, the closed ring 16 formed by the free end of the flexible strap of the special binding strap is exposed on the inner side of the insulation board 4 (towards the cast-in-place exterior wall), while the rigid unit, steel mesh and pad block and other structural components or other embedded parts are embedded in the lightweight concrete.

[0027] like Figure 3 , 3a As shown, when the precast lightweight concrete insulation board 4 is hoisted to the outside of the cast-in-place exterior wall, the closed ring 16 formed by the free end 11a of the flexible clip faces the steel mesh 6 of the cast-in-place layer 5 of the exterior wall. When binding or welding the vertical steel bars of the steel mesh, it is preferable to pass the vertical steel bars through the closed ring 16 formed by the free end of the flexible clip before pouring the cast-in-place layer 5 of the exterior wall. This reliably connects the precast lightweight concrete insulation board 4 to the outside of the exterior wall, meeting the requirements of exterior wall insulation.

[0028] like Figure 1 , 1aAs shown in Figures 4 and 5, in the above embodiments, it is preferable to provide a connecting through hole 2a on the pad block. The free end 11a of the flexible strap of the special binding strap passes through the connecting through hole 2a and then loops back to the positioning frame 12, thereby reliably connecting the pad block 2 to the bottom side of the reinforcing mesh 1 and preventing the pad block 2 from detaching from the reinforcing mesh 1. It is also preferable to provide a groove 2b on the side of the pad block 2 facing the reinforcing mesh. The groove 2b matches the reinforcing bars of the reinforcing mesh 1. When the special binding strap 10 positions the pad block 2 on the bottom side of the reinforcing mesh 1, the reinforcing bars of the reinforcing mesh 1 are precisely inserted into the groove 2b of the pad block, thereby reliably positioning the pad block 2 on the bottom side of the reinforcing mesh 1 and preventing the pad block from shifting during the pouring of lightweight concrete in the production process, thus preventing it from failing to provide effective support for the reinforcing mesh.

[0029] The lightweight concrete used in the precast lightweight concrete insulation board described in this utility model can be modified polystyrene particle concrete, ceramsite concrete, or aerated concrete, etc.

[0030] Based on the embodiments of this utility model, any modifications, equivalent substitutions, improvements, etc., made by all other embodiments obtained by those skilled in the art without creative effort should be included within the protection scope of this utility model.
