Description

Technical Field

[0001] This application relates to the field of connectors for exterior wall decorative panels, and more specifically, to a connector for assembling integrated insulation panels. Background Technology

[0002] Integrated insulation board is an exterior wall building material that integrates insulation function with building structure function. It is prefabricated in the factory to rigidly connect the insulation layer with the concrete structure, thereby achieving the goal of insulation and wall with the same life. The core advantage of integrated insulation board is that it solves the problems of easy detachment and cracking of traditional external insulation.

[0003] In related technologies, integrated insulation boards have a fixed number of insulation nails inserted within a specified area, and are poured simultaneously with the concrete through these pre-installed nails. Before pouring the concrete exterior wall, the insulation nails are inserted through the integrated insulation board, with their extended sections reaching into the structural reinforcement of the concrete exterior wall. During the pouring of the concrete exterior wall, the extended sections of the insulation nails engage with the concrete, thus achieving mechanical anchoring between the integrated insulation board and the concrete exterior wall.

[0004] However, in actual use, because the extended section of traditional insulation nails is a single straight rod structure, its combined area with the concrete is only the surface area of ​​the rod. In high-rise buildings, under strong wind pressure, seismic vibration, or long-term self-weight, the anchoring points are prone to failure due to stress concentration, which can lead to the insulation board falling off. Summary of the Invention

[0005] In view of this, the present application provides a connector for assembling integrated insulation boards to solve the problem that traditional insulation nails have a small anchoring area, which can easily lead to insulation boards falling off in high-rise buildings.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A connector for assembling integrated insulation panels, comprising:

[0008] An insulating sleeve, comprising a cap and a connected cylinder, wherein the cylinder is flexibly connected with multiple barbs and its outer wall is formed with a continuous spiral thread.

[0009] The reinforcing bar is coaxially inserted into the cylinder, and threaded holes for fastening bolts are provided at its top and bottom; the reinforcing bar is fixedly connected to the insulation sleeve by fastening bolts that pass through the cap, and its length is greater than the length of the cylinder.

[0010] An anchoring sleeve is fitted onto the protruding section of the reinforcing bar and has an interference fit with it. Multiple anchoring plates are flexibly connected to its bottom in the radial direction. In the initial state, the anchoring plates are folded upward in the axial direction at the flexible connection.

[0011] An abutment spring is sleeved outside the anchoring sleeve, with its two ends abutting against the bottom surface of the cylinder and multiple anchoring plates, so that the anchoring plates extend radially outward.

[0012] In some possible implementations, the bottom surface of the cap has multiple circular protrusions evenly distributed around the circumference, which elastically contact the surface of the insulation board through the circular protrusions.

[0013] In some possible implementations, the anchoring sleeve is smaller than the protruding length of the reinforcing bar, and the surface of the reinforcing bar is provided with anchoring patterns.

[0014] In some possible implementations, the length of the cylinder is greater than the thickness of the insulation board, and an annular plate is provided at its bottom to abut against the abutment spring.

[0015] In some possible implementations, the anchor sleeve has a pre-drilled hole in the central area of ​​its bottom surface, through which it is connected to the reinforcing bar by bolts.

[0016] In some possible implementations, the elastic force of the abutment spring is less than the frictional force between the anchor sleeve and the reinforcing bar.

[0017] This application provides a connector for assembling an integrated insulation board, which has at least the following features:

[0018] Beneficial effects:

[0019] In a connector for assembling integrated insulation panels provided in this application embodiment, the insulation sleeve has flexible barbs and a continuously threaded structure on its outer shell. When the insulation sleeve is inserted into the insulation panel, the barbs spring back and clamp the internal gaps of the insulation panel, and the threaded structure increases the contact area and friction between the sleeve and the insulation panel. Simultaneously, the anchoring sleeve and the deployable anchoring plate form a radially distributed anchoring structure, thereby increasing the interlocking anchoring area with the concrete. Using this structural design, the insulation nails can be fixed to both the insulation panel and the concrete exterior wall, meeting the anti-fall-off requirements of high-rise buildings.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1-4As shown in the embodiment of this application, a connector for assembling an integrated insulation board includes an insulation sleeve 100, a reinforcing bar 200, an anchoring sleeve 300, and a retaining spring 400. The insulation sleeve 100 is a plastic component of the insulation nail connector, which can be integrally injection molded from modified polypropylene and possesses good elasticity and weather resistance. The insulation sleeve 100 consists of a cap 110 and a cylindrical body 120 fixedly connected to the central area of ​​its bottom surface. The cap 110 is a disc-shaped structure with a diameter larger than that of the cylindrical body 120. Multiple barbs 121 are flexibly connected to the outside of the cylindrical body 120. In the initial state, the angle between the centerline of the multiple barbs 121 and the axis of the cylindrical body 120 is an acute angle. Furthermore, continuous threads 122 are machined onto the outside of the cylindrical body 120. The threads 122 further increase the contact area with the insulation board, thereby improving the friction between the two.

[0032] The reinforcing bar 200 is inserted into the cylinder 120 of the insulation sleeve 100. In this embodiment, the reinforcing bar 200 can replace the traditional nail. A threaded hole 210 is formed at the top of the reinforcing bar 200 along the axial direction. The reinforcing bar 200 is fixed inside the cylinder 120 by a fastening bolt passing through the cap 110 of the insulation sleeve 100. Furthermore, the overall length of the reinforcing bar 200 is greater than the length of the cylinder 120, and the length of the cylinder 120 is adapted to the thickness of the insulation board. Therefore, when the insulation sleeve 100 and the reinforcing bar 200 are inserted into the insulation board, the protruding section at the end of the reinforcing bar 200 extends outside the insulation board and inserts into the structural reinforcing bar 200 of the concrete exterior wall, ready for subsequent concrete pouring and anchoring.

[0033] In this embodiment, the anchor sleeve 300 is fitted onto the protruding section at the end of the reinforcing bar 200 with an interference fit. Multiple anchor plates 310 are flexibly connected radially to the bottom of the anchor sleeve 300 via elastic folds. In the initial state, the anchor plates 310 are folded upwards along the axial direction of the anchor sleeve 300. Preferably, a pre-drilled hole 330 is provided in the central area of ​​the bottom surface of the anchor sleeve 300, through which it is fixedly connected to the reinforcing bar 200 by bolts.

[0034] Continue as Figures 1-4 As shown, the abutment spring 400 is sleeved outside the anchoring sleeve 300. Both ends of the abutment spring 400 abut against the bottom surface of the cylinder 120 and the anchoring plate 310, respectively, causing multiple anchoring plates 310 to extend radially outward, thus forming radially extending anchoring plates 310. Furthermore, the elastic force of the abutment spring 400 is less than the frictional force between the anchoring sleeve 300 and the reinforcing bar 200. This allows the abutment spring 400 to expand and extend the anchoring plates 310 outward while preventing the anchoring sleeve 300 from falling off. Preferably, the length of the cylinder 120 is greater than the thickness of the insulation board, and the bottom of the cylinder 120 is provided with an annular plate 320 that abuts against the abutment spring 400.

[0035] The following is combined Figures 1-4 The assembly steps and working principle of the connectors for assembling integrated insulation boards provided in the embodiments of this application are described.

[0036] Insert the reinforcing bar 200 coaxially from the bottom of the cylinder 120, aligning the threaded hole 210 at the top of the reinforcing bar 200 with the bolt hole of the cap 110. Then, screw the fastening bolt into the threaded hole 210 from the top of the cap 110 until the head of the fastening bolt is in contact with the top surface of the cap 110, thus achieving a fixed connection between the reinforcing bar 200 and the insulation sleeve 100. Insert the anchoring sleeve 300 from the bottom of the protruding section of the reinforcing bar 200. Similarly, place the abutment spring 400 on the outside of the cylinder 120. The two ends of the abutment spring 400 abut against the bottom of the cylinder 120 and the anchoring plate 310, respectively. At this time, the anchoring plate 310 is folded upward under the pressure of the abutment spring 400 and extends radially outward.

[0037] When the barbs 121 of the insulation sleeve 100 are inserted into the insulation board, they are compressed and elastically bent. After passing through the insulation board, they return to their initial acute angle state to lock onto the inner surface of the insulation board, thus forming a one-way locking. The threads 122 provided on the outside of the sleeve 120 can increase the contact area between the sleeve 120 and the insulation board, dispersing the pull-out force to a larger area to avoid local stress concentration.

[0038] Furthermore, after the abutment spring 400 releases its elastic force, it pushes the anchor plate 310 to unfold radially outward, and multiple anchor plates 310 form a mechanical barrier with the structural steel reinforcement 200. After the concrete exterior wall is poured, the anchor sleeve 300, abutment spring 400, steel reinforcement 200, and anchor plates 310 will form a rigid whole with the concrete exterior wall. In this way, the pull-out force can be transmitted to the structural steel reinforcement 200 in the concrete exterior wall through the large interlocking surface of the anchor plate 310, thereby significantly improving the pull-out bearing capacity of the insulation board.

[0039] In some embodiments, the bottom surface of the cap 110 has a plurality of circular protrusions 111 evenly distributed along the circumference, and the cap 110 makes elastic contact with the surface of the insulation board through the plurality of circular protrusions 111. In actual use, the integrated insulation board is prone to thermal expansion and contraction due to changes in ambient temperature. The cap 110 makes elastic contact with the surface of the insulation board through the circular protrusions 111, and can absorb the expansion and contraction displacement of the insulation board through its own slight deformation, avoiding cracking caused by stress concentration at the contact point between the connector and the insulation board, thereby solving the problem of surface damage caused by hard contact of traditional insulation nails.

[0040] In some embodiments, the anchor sleeve 300 is shorter than the protruding length of the reinforcing bar 200, and the surface of the reinforcing bar 200 is provided with anchoring patterns 220. This structural design allows the exposed portion of the protruding section of the reinforcing bar 200 to directly contact the concrete, and the anchoring patterns 220 on the surface further increase the frictional engagement area between the reinforcing bar 200 and the concrete, thereby further enhancing the pull-out bearing capacity of the concrete end.
