Description

Technical Field

[0001] The utility model relates to the technical field of construction and installation of thermal insulation boards, in particular to a connecting piece for built-in thermal insulation boards. Background Art

[0002] In the construction field, insulation boards are used more and more widely, and their connectors play a vital role.

[0003] At present, in the field of insulation board connection technology, common connectors have many problems. Some existing insulation board connectors often use simple hook or slot structures when connecting steel meshes, but the stability of this structure is poor. During the clamping process, the steel mesh cannot be tightly fixed, and the steel mesh is prone to falling off. For example, some slots do not have elastic limiting components. When subjected to external vibrations or pressure changes, the steel mesh can easily slip out of the slot, which not only affects the connection stability between the insulation board and the external structure, but may also cause the overall structure of the insulation board to become loose due to loose connections, thereby reducing the insulation performance.

[0004] At the same time, if only a single connection component such as an ordinary screw is used for fixing, once the screw becomes loose or falls off, the docking piece will separate from the insulation board, causing the insulation board to be unable to be used normally, increasing maintenance costs and safety hazards. In addition, the structural design of traditional connectors is not reasonable. The shapes are mostly circular or regular quadrilaterals, which are difficult to locate during installation and inconvenient to operate, affecting construction efficiency. In addition, due to the limited contact area and concentrated force, it is easy for the connector or insulation board to be damaged and deformed.

[0005] For this purpose, we propose a connecting piece for a built-in thermal insulation panel. Utility Model Content

[0006] The utility model mainly solves the above-mentioned existing technical problems and provides a connecting piece for a built-in thermal insulation board.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a connecting piece for a built-in insulation board, comprising an insulation board body, docking piece bodies are symmetrically arranged on both sides of the insulation board body, a threaded long rod is connected between the two docking piece bodies, the threaded long rod passes through both sides of the insulation board body, and a fixing component connected to the corresponding end faces of the insulation board body is arranged between the two docking piece bodies, steel mesh is arranged on both sides of the insulation board body, and a limiting component for clamping the steel mesh is arranged at one end of the two docking piece bodies away from each other, the limiting component comprises a limiting head and a cross-shaped slot provided on the limiting head, the intersection of the warp and weft of the steel mesh is clamped into the cross-shaped slot and clamped with the limiting head, and two groups of elastic intercepting blocks are arranged at both ends of the groove of each cross-shaped slot, and a sealing plate that is clamped on the corresponding four cross-shaped slots is arranged on the outer side of the limiting head.

[0008] Preferably, the fixing assembly includes a fixing sleeve located on the end surface of the docking member body and a first bolt threadedly connected inside the fixing sleeve.

[0009] Preferably, a connecting pipe connected to the interior of the fixing sleeve is transversely installed on the outer side of each fixing sleeve, and a second bolt extending into the interior of the fixing sleeve is threadedly connected to the connecting pipe.

[0010] Preferably, the seal comprises a cross-shaped baffle, four ports of the baffle are connected to L-shaped protrusions, and the L-shaped protrusions are clamped on a group of interception blocks on the opening of the cross-shaped clamping slot.

[0011] Preferably, each docking piece body is an octagonal structure.

[0012] Beneficial Effects

[0013] The utility model provides a connector for a built-in insulation board, which has the following beneficial effects:

[0014] 1. The cross-shaped slot of the limit head cooperates with the elastic interception block to accurately and firmly clamp the intersection of the longitude and latitude of the steel mesh, effectively preventing the steel mesh from shifting or falling off during use, and ensuring the stability of the connection between the insulation board and the external structure. The setting of the sealing plate not only further limits the movement of the steel mesh, but also seals and limits the threaded long rod, reducing the risk of the threaded long rod falling off due to loose nuts, and enhancing the safety of the overall structure of the insulation board.

[0015] 2. The fixing assembly consisting of the fixing sleeve, the first bolt, the connecting pipe and the second bolt further strengthens the connection firmness between the connecting piece body and the insulation board body on the basis of the long threaded rod connecting the two connecting piece bodies. Even if the long threaded rod falls off, the connecting piece body can still be stably fixed on the insulation board body, avoiding failure of the insulation board connecting piece, ensuring the reliability of the insulation board during use, and extending the service life of the insulation board.

[0016] 3. The main body of the docking piece adopts an octagonal structure, which is easy to position and operate during the installation process, improving the efficiency of construction and installation. At the same time, the octagonal structure increases the contact area with the insulation board body, disperses the force, makes the connection more stable, and reduces the possibility of damage to the connector or deformation of the insulation board due to excessive local force, which helps to improve the stability and durability of the entire insulation system.

[0026] The following will be combined with the drawings in 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.

[0027] Embodiment 1: A connector for a built-in insulation board, such as Figure 1 - Figure 4As shown; it includes an insulation board body 1, and a docking body 2 is symmetrically arranged on both sides of the insulation board body 1, and each docking body 2 is an octagonal structure. A threaded long rod 3 is connected between the two docking body 2, and the threaded long rod 3 runs through both sides of the insulation board body 1. A fixing component connected to the corresponding end faces of the insulation board body 1 is arranged between the two docking body 2. A steel mesh 4 is arranged on both sides of the insulation board body 1, and each steel mesh 4 is composed of criss-cross mesh steel bars. A limiting component for clamping the steel mesh 4 is arranged at one end of the two docking body 2 away from each other. The limiting component includes a limiting head 201 and a cross-shaped card slot 202 on the limiting head 201, and the intersection of the warp and weft of the steel mesh 4 is clamped into the cross-shaped card slot 202 and is clamped with the limiting head 201. And two sets of elastic interception blocks 203 are arranged at both ends of the groove of each cross-shaped card slot 202.

[0028] When the longitude and latitude intersection of the steel mesh 4 is stuck in the cross-shaped slot 202, the longitude and latitude intersection of the steel mesh 4 will first squeeze the corresponding interception block 203, and insert the longitude and latitude intersection of the steel mesh 4 into the corresponding four cross-shaped slots 202. After the longitude and latitude intersection of the steel mesh 4 is installed in the cross-shaped slot 202, the interception block 203 inside the cross-shaped slot 202 recovers its deformation, and the longitude and latitude intersection of the steel mesh 4 can be limited inside the cross-shaped slot 202, and it will not fall off. The outer side of the limit head 201 is provided with a sealing plate that is buckled on the corresponding four cross-shaped slots 202.

[0029] The fixing assembly includes a fixing sleeve 5 located on the end surface of the docking member body 2 and a first bolt 501 threadedly connected inside the fixing sleeve 5. After the two docking member bodies 2 are docked on both sides of the insulation board body 1 through the threaded long rod 3, the docking member body 2 can be further fixed to the adjacent end of the insulation board body 1 through the fixing assembly. The threaded long rod 3 is prevented from falling off between the two docking member bodies 2, and the docking member body 2 will not fall off from the outside of the insulation board body 1.

[0030] A connecting pipe 502 connected to the inside of the fixing sleeve 5 is transversely installed on the outside of each fixing sleeve 5, and a second bolt 503 extending to the inside of the fixing sleeve 5 is threadedly connected to the connecting pipe 502. By arranging the connecting pipe 502 and the second bolt 503 on the fixing assembly, the first bolt 501 can be prevented from falling off from the inside of the fixing sleeve 5, and the docking member body 2 can be prevented from falling off and shifting on the insulation board body 1, thereby enhancing the stability of the fixing assembly on the docking member body 2.

[0031] Embodiment 2, based on embodiment 1, as Figure 5 and Figure 6As shown in the figure, further, the sealing plate includes a cross-shaped baffle 6, and the four ports of the baffle 6 are connected to the L-shaped protrusions, and the L-shaped protrusions are clamped on a group of interception blocks 203 on the opening of the cross-shaped slot 202. The baffle 6 is arranged at the opening of the limit head 201 of the docking part body 2, and the opening of the cross-shaped slot 202 can be sealed. On the one hand, the longitude and latitude intersection of the steel mesh 4 inside the cross-shaped slot 202 can be limited, and on the other hand, the threaded long rod 3 connecting the two sets of docking part bodies 2 can be limited to prevent the nut on the threaded long rod 3 from loosening and causing the threaded long rod 3 to fall off between the two docking part bodies 2.

[0032] Working principle of the utility model: For the steel mesh connection part, first align the intersection of the warp and weft of the steel mesh 4 with the cross-shaped slot 202 on the limit head 201. During the insertion process, the intersection of the warp and weft of the steel mesh 4 will squeeze the interception block 203. Since the interception block 203 is elastic, it will deform to allow the steel mesh 4 to smoothly enter the cross-shaped slot 202. When the steel mesh 4 is fully inserted, the interception block 203 restores its deformation and tightly clamps the steel mesh 4 in the cross-shaped slot 202. The baffle 6 of the sealing plate is clamped on the interception block 203 through its L-shaped protrusion to seal the opening of the cross-shaped slot 202, which not only further fixes the steel mesh 4, but also limits the threaded long rod 3 to prevent it from falling off due to the loosening of the nut on the threaded long rod 3.

[0033] The two docking parts 2 are fixed to the insulation board by the threaded long rod 3 penetrating the two sides of the insulation board body 1 to achieve preliminary docking and positioning. Then the fixing assembly is used for further fixing, and the first bolt 501 is screwed into the fixing sleeve 5 to tightly connect the adjacent end faces of the docking part body 2 and the insulation board body 1. The connecting pipe 502 and the second bolt 503 play an auxiliary fixing role. The second bolt 503 is connected to the connecting pipe 502 by thread and extends to the inside of the fixing sleeve 5 to prevent the first bolt 501 from falling off from the fixing sleeve 5, thereby ensuring the stable connection of the docking part body 2 on the insulation board body 1. Even if the threaded long rod 3 falls off from between the docking part bodies 2 in an unexpected situation, the docking part body 2 can still be firmly connected to the insulation board body 1.

[0034] The connection and fixation of the steel mesh 4 is achieved through the cross-shaped slot 202 on the limit head 201 and the elastic interception block 203. The intersection of the warp and weft of the steel mesh 4 is inserted into the cross-shaped slot 202, and the interception block 203 is squeezed during the insertion process. After the insertion, the interception block 203 recovers its deformation to limit it.

[0035] Advantages: The steel mesh 4 can be firmly fixed on the docking body 2 to prevent the steel mesh 4 from falling off. The sealing plate further strengthens the fixation of the steel mesh 4 and the limiting effect on the threaded long rod 3. The L-shaped protrusion of the baffle 6 is clamped on the interception block 203, sealing the opening of the cross-shaped slot 202, limiting the position of the steel mesh while preventing the nut on the threaded long rod 3 from loosening and causing it to fall off.

[0036] By using the fixing sleeve 5 and the first bolt 501 in the fixing assembly, after the two butt-jointed body parts 2 are butt-jointed through the threaded long rod 3, the first bolt 501 is threadedly connected in the fixing sleeve 5 and fixed to the end surface of the insulation board body 1. The connecting pipe 502 and the second bolt 503 further strengthen the fixing effect.

[0037] Advantages: Even if the threaded rod 3 falls off, the docking member body 2 will not fall off from the outside of the insulation board body 1. The connecting pipe 502 and the second bolt 503 prevent the first bolt 501 from falling off, thereby enhancing the stability of the fixing assembly on the docking member body 2.

[0038] The docking piece body 2 is an octagonal structure. Compared with a circular or other shape, the octagonal structure is easier to position and operate during installation or in conjunction with other parts, making it convenient for construction workers to perform installation and docking work, thereby improving installation efficiency. At the same time, the octagonal structure can increase the contact area with the insulation board body 1 to a certain extent, making the connection more stable, dispersing the force, and improving the stability of the overall structure. Each component cooperates with each other to form a relatively stable and efficient insulation board connector system, which is conducive to improving the use effect and safety of the insulation board in the fields of construction.
