Abstract
Description
Technical Field
[0001] This utility model relates to the field of insulation board connection technology, and in particular to a wall insulation board connection structure. Background Technology
[0002] Wall insulation boards are a core component of building energy-saving systems. The reliability, adaptability, and insulation integrity of their connection structure directly determine the building's energy-saving effect and durability. Currently, the mainstream insulation board connection technologies in the industry still have many technical pain points. For example, traditional insulation board fixing mostly relies on the piercing installation of insulation nails. The insulation nails need to penetrate the insulation board body and be fixed to the wall. This process will damage the airtight insulation structure of the insulation board, forming a "thermal bridge" channel, resulting in local heat loss. Moreover, the piercing holes are easy to become paths for rainwater and moisture to penetrate, accelerating the internal moisture aging of the insulation board and shortening its service life. At the same time, some solutions use adhesive splicing or simple metal clips. Adhesives are easily aged and fail due to the influence of environmental temperature and humidity. Especially in high or low temperature environments, the bonding strength will drop rapidly, causing the insulation board splice to crack and fall off. Simple metal clips are mostly designed with fixed size and can only be used for insulation boards of a single thickness (such as the common 50mm or 100mm). They cannot meet the differentiated insulation thickness requirements of different buildings, have poor versatility, and the clips can only limit the insulation board in one direction. The corners of the board are not firmly fixed, and gaps are likely to appear in the splice after long-term use.
[0003] Therefore, it is necessary to provide a new wall insulation board connection structure to solve the above-mentioned technical problems. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a wall insulation board connection structure.
[0005] The wall insulation board connection structure provided by this utility model includes an L-shaped frame, and L-shaped grooves are provided on both sides of the L-shaped frame. Each L-shaped groove is equipped with an L-shaped elastic corrugated metal sheet and a fastening component for pressing the insulation board.
[0006] The fastening component includes a threaded rod, which is inserted into a threaded hole on the front end face of the L-shaped frame and threadedly connected to the threaded hole. The inserted end of the threaded rod extends into an L-shaped groove and is connected to a rotatably connected pressing plate.
[0007] Preferably, each L-shaped groove is provided with two sets of fastening components. The pressing plate in one set of fastening components is arranged vertically and corresponds to the vertical part of the L-shaped groove, and the pressing plate in the other set of fastening components is arranged horizontally and corresponds to the horizontal part of the L-shaped groove.
[0008] Preferably, a knob is fixedly installed on the outer end of the threaded rod.
[0009] Preferably, the L-shaped elastic corrugated metal sheet is fixedly fitted onto the groove wall of the L-shaped groove away from the threaded hole.
[0010] Preferably, the middle plate of the L-shaped frame has a U-shaped groove, and the U-shaped groove has a waist-shaped cavity that penetrates the L-shaped frame.
[0011] Preferably, the horizontal plates of the two sets of L-shaped frames are arranged opposite each other to form a cross structure, and a U-shaped tie plate is installed between the two sets of L-shaped frames. The U-shaped tie plate is inserted into the U-shaped groove opened in the two sets of L-shaped frames, and a waist-shaped through hole is opened on the U-shaped tie plate.
[0012] Preferably, reinforcing ribs are fixedly provided between the vertical and horizontal plate sections of the L-shaped frame.
[0013] Compared with related technologies, the wall insulation board connection structure provided by this utility model has the following advantages:
[0014] This invention utilizes the L-shaped groove of the L-shaped frame to support the corners of the insulation board. When the threaded rod of the fastening component is screwed in along the threaded hole, the pressing plate can directly press the corners of the insulation board, eliminating the need for insulation nails to pierce the insulation layer. This fundamentally preserves the sealed structure of the insulation board, eliminating thermal bridges and moisture penetration paths, and greatly improving the insulation effect of the insulation board. Since the L-shaped elastic corrugated metal sheet is an elastic structure, it reduces the risk of insulation board connection failure due to wall vibration. Furthermore, the L-shaped elastic corrugated metal sheet provides continuous reverse elastic force after compression, assisting in clamping the insulation board. There is no need to replace connectors of different sizes, and its adaptability far exceeds that of traditional fixing clips. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0026] Please see Figures 1 to 8 The present invention provides a wall insulation board connection structure, which includes an L-shaped frame 1, an L-shaped elastic corrugated metal sheet 2, and fastening components 3.
[0027] In the embodiments of this utility model, please refer to Figures 1 to 4 The L-shaped frame 1 has L-shaped grooves 1a on both sides and a U-shaped groove 1b on the middle plate surface. The U-shaped groove 1b has a waist-shaped cavity 1c that penetrates the L-shaped frame 1. Each L-shaped groove 1a has an L-shaped elastic corrugated metal sheet 2 and a fastening component 3 for pressing the insulation board. The fastening component 3 includes a threaded rod 31, which is inserted into a threaded hole 1d on the front end face of the L-shaped frame 1 and threadedly connected to the threaded hole 1d. The insertion end of the threaded rod 31 extends into the L-shaped groove 1a and is connected to a rotatably connected pressing plate 32. A knob 33 is fixedly installed on the outer head of the threaded rod 31. The L-shaped elastic corrugated metal sheet 2 is fixedly embedded in the groove wall of the L-shaped groove 1a away from the threaded hole 1d.
[0028] It should be noted that when connecting two insulation boards, two sets of L-shaped brackets 1 are set up. The upper and lower corners of the two insulation boards are inserted into the L-shaped grooves 1a on the same side of the two sets of L-shaped brackets 1. At this time, the corners of the insulation boards abut against the L-shaped elastic corrugated metal sheet 2, causing the L-shaped elastic corrugated metal sheet 2 to be compressed. Then, the knob 33 is turned to drive the threaded rod 31 to screw in along the threaded hole 1d. Therefore, the pressing plate 32 can firmly press the corners of the insulation boards that are inserted. Thus, it is possible to connect insulation boards of different thicknesses. Then, another insulation board to be connected is fixed in the same way (as shown in the attached figure). Figure 7 As shown in the figure, after the connection is completed, the insulation board can be quickly fixed to the wall by passing the insulation nail through the waist cavity 1c. Therefore, it is not necessary to pass the insulation nail through the insulation board, which protects the insulation board and reduces the risk of reduced insulation effect of the insulation board due to the piercing fixation of the insulation nail.
[0029] Among them, the L-shaped groove 1a of the L-shaped frame 1 supports the corner of the insulation board. When the threaded rod 31 of the fastening component 3 is screwed in along the threaded hole 1d, the pressing plate 32 can directly press the corner of the insulation board without the need for insulation nails to pierce the insulation layer. This fundamentally preserves the sealed structure of the insulation board, eliminates "thermal bridges" and water vapor penetration paths, and greatly improves the insulation effect of the insulation board.
[0030] It is worth noting that: because the L-shaped elastic corrugated metal sheet 2 is an elastic structure, the L-shaped elastic corrugated metal sheet 2 can reduce the risk of insulation board connection failure due to wall vibration in terms of structural form. Moreover, the L-shaped elastic corrugated metal sheet 2 can provide continuous reverse elastic force after compression, which helps to clamp the insulation board. There is no need to replace the connectors of different sizes, and its adaptability is far superior to traditional fixing buckles.
[0031] In addition, the L-shaped elastic corrugated metal sheet 2 in this application is made of elastic metal materials such as spring steel or nickel-chromium alloy. Its corrugated structure can generate elastic deformation when the building vibrates or the temperature changes, absorb the impact energy, avoid rigid collision between the insulation board and the L-shaped frame 1, and reduce the risk of connection failure. At the same time, the L-shaped elastic corrugated metal sheet 2 is hot-dip galvanized or sprayed with fluorocarbon weather-resistant coating to improve its corrosion resistance.
[0032] In this embodiment: after the insulation board is installed on the wall, cement is filled into the gap between the two insulation boards.
[0033] Furthermore, each L-shaped groove 1a is provided with two sets of fastening components 3. The pressing plate 32 in one set of fastening components 3 is vertically arranged and corresponds to the vertical part of the L-shaped groove 1a, and the pressing plate 32 in the other set of fastening components 3 is horizontally arranged and corresponds to the horizontal part of the L-shaped groove 1a. Thus, the corner of the insulation board inserted into the L-shaped groove 1a is fastened by the two sets of fastening components 3. Specifically, the vertical pressing plate 32 corresponds to the vertical part of the L-shaped groove 1a, restricting the vertical movement of the insulation board, while the horizontal pressing plate 32 corresponds to the horizontal part of the L-shaped groove 1a, restricting the left and right sliding of the insulation board. This achieves "two-way locking" of the corner of the insulation board, avoiding stress concentration and loosening caused by unidirectional limiting.
[0034] Among them, the vertical plate segment and the horizontal plate segment of the L-shaped frame 1 are fixedly supported by reinforcing ribs 11, which improves the strength of the L-shaped frame 1.
[0035] In the embodiments of this utility model, please refer to Figure 1 , Figure 5 and Figure 6 The horizontal plates of the two sets of L-shaped frames 1 are arranged opposite each other to form a cross structure, and a U-shaped tie plate 4 is installed between the two sets of L-shaped frames 1. The U-shaped tie plate 4 is inserted into the U-shaped groove 1b opened in the two sets of L-shaped frames 1, and a waist-shaped through hole 4a is opened on the U-shaped tie plate 4.
[0036] It should be noted that when connecting the four insulation boards, the horizontal plates of the two sets of T-shaped frames 1 are arranged opposite each other to form a cross structure. Then, the two U-shaped tie plates 4 are respectively fastened into the U-shaped grooves 1b opened in the two sets of T-shaped frames 1 to achieve the snap-fit connection between the two sets of T-shaped frames 1. After the connection is completed, the four insulation boards are installed in the same way as when installing two insulation boards (as shown in the attached diagram). Figure 8 As shown), the two sets of horizontal plates of the L-shaped frame 1 are arranged opposite each other to form a cross structure. With the U-shaped tie plate 4 inserted into the U-shaped groove 1b, the four insulation boards can be quickly connected, thus eliminating the need to install multiple sets of connectors in stages, which shortens the construction time and reduces the splicing gaps.
[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
