Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a wall insulation layer anti-detachment fixing structure. Background Technology

[0002] Wall insulation is an important component of modern building energy conservation. Insulation boards are bonded to the base wall of a building using adhesive mortar.

[0003] However, relying solely on the bonding mortar for fixing can lead to bonding failure when faced with wind pressure, temperature stress changes, or the weight of the insulation board in high-rise buildings. This can result in large-area hollowing or even detachment of the insulation layer. To solve this problem, existing technologies use mechanical anchors, such as insulation nails, which are driven through the insulation board into the base wall as an auxiliary fixing method.

[0004] While these conventional insulation nails provide mechanical tension, their structure still has flaws. The insulation board is made of a relatively loose or soft material, and the nail head has a limited contact area. Under continuous negative wind pressure or tension, the nail head will experience stress concentration, which can tear through the insulation board, causing the anchor point to fail and the insulation board to loosen.

[0005] Furthermore, the stress is most concentrated at the corners of the wall, especially at the junction of the insulation board and the ground or floor slab, making it a weak point where deformation and warping occur. Existing fixing methods mostly use insulation nails that are the same as the center of the wall, lacking a reinforced three-dimensional anchoring structure for this critical area. This causes the corners to loosen first during long-term use, leading to a chain reaction of detachment.

[0006] Therefore, this utility model proposes a wall insulation layer anti-detachment fixing structure to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems in the existing wall insulation layer anti-detachment fixing structure, such as weak connection at the corners, warping and detachment due to stress concentration, and limited holding force of the fixing nail heads on the insulation board, which leads to tearing failure, this utility model aims to provide a wall insulation layer anti-detachment fixing structure with improved structure that can effectively solve the above problems.

[0008] This utility model provides a wall insulation layer anti-detachment fixing structure, including: insulation board, base layer located inside the insulation board, and cement floor located at the bottom of the insulation board and the base layer, as well as edge fixing mechanism and surface fixing mechanism.

[0009] The edge fixing mechanism is located at the junction of the insulation board and the cement floor. The edge fixing mechanism includes a base, a clamping plate is fixedly connected to the right end of the base, the clamping plate is embedded in the base layer, and a pressure ring is fixedly connected to the left end of the base, the pressure ring is tightly attached to and presses against the outer wall of the insulation board.

[0010] Furthermore, the edge fixing mechanism also includes through bolts, which sequentially penetrate the inner wall of the pressure ring, the insulation board, and part of the cement floor, and are threadedly connected to the clamping plate. The bottom of the base is fixedly connected to the cement floor. The surface fixing mechanism includes fixing nails that pass through the insulation board and are driven into the base layer.

[0011] Preferably, the top of the cement floor has a base groove, the base is shaped to fit and is fitted inside the base groove, and the upper surface of the base is flush with the upper surface of the cement floor.

[0012] Preferably, the edge securing mechanism further includes a fixing anchor that penetrates the base and is anchored in the cement floor.

[0013] Preferably, the base has an inner groove, in which the head of the through bolt is accommodated, and the inner groove corresponds to the position of the pressure ring.

[0014] Preferably, the card plate has a screw hole, and the tail of the through bolt is threaded into the screw hole.

[0015] Preferably, the surface fixing mechanism includes a number of dispersed fixing nails. Each fixing nail includes a rod and a nail head fixedly connected to the left end of the rod. The rod of the fixing nail horizontally penetrates the insulation board and is driven into the base layer, while the nail head abuts against and presses against the outer surface of the insulation board.

[0016] Preferably, the shank of the fixing nail has an annular slit near the nail head.

[0017] Preferably, the circumferential gap is filled with adhesive blocks, which cure within the circumferential gap and bond with the material of the insulation board, thereby forming an auxiliary fixing surface between the nail head and the insulation board.

[0018] Preferably, the wall insulation layer anti-detachment fixing structure also includes a decorative layer, which covers the outer wall of the insulation board and the outer side of the surface fixing mechanism.

[0019] This utility model has the following beneficial effects: 1. This utility model, by setting an edge fixing mechanism at the corner of the wall, uses through bolts, pressure rings and pre-embedded clamps in the base layer to lock the insulation board, base layer and cement floor into a whole structure, solves the problem of the corner of the insulation layer as a weak link in the prior art, which causes warping and falling off due to stress concentration. It can three-dimensionally anchor the corner of the wall, improve the connection reliability and tensile strength.

[0020] 2. This utility model, by setting up a surface fixing mechanism, has an annular gap near the nail head of the fixing nail, which is filled with adhesive block. This solves the problem in the prior art that the fixing nail relies solely on the physical pressing of the nail head, resulting in a small contact area and failure to fix due to pulling through the insulation board. It can use adhesive block to form an auxiliary fixing surface between the nail head and the insulation board, realizing a combination of mechanical anchoring and chemical bonding, and improving the pull-out resistance of the fixing nail.

The surface fixing mechanism 6 includes several connecting components distributed on the surface of the insulation board 2. The surface fixing mechanism 6 penetrates the insulation board 2 horizontally and is anchored into the base layer 3 to provide continuous tension. The outermost layer of the wall insulation layer anti-detachment fixing structure is also provided with a decorative layer 1. The decorative layer 1 covers the outer wall of the insulation board 2 and the outer side of the surface fixing mechanism 6. The decorative layer 1 is used to cover the internal fixing components and provide protection and beautification functions for the building facade.

[0026] Please refer to Figures 1 to 3 and Figure 5 The edge-fixing mechanism 5 provides three-dimensional anchoring and locking at the junction of the insulation board 2 and the cement floor 4. The edge-fixing mechanism 5 includes a base 501, with a clamping plate 503 fixedly connected to the right end of the base 501. The clamping plate 503 is embedded inside the base layer 3. A pressure ring 506 is fixedly connected to the left end of the base 501, pressing tightly against and pressing the outer wall of the insulation board 2. The edge-fixing mechanism 5 also includes a through bolt 507, which sequentially penetrates the inner wall of the pressure ring 506, the insulation board 2, and part of the cement floor 4. A screw hole 504 is provided on the clamping plate 503, and the tail of the through bolt 507 engages with the screw hole 504 to achieve locking and fixing. The bottom of the base 501 is fixedly connected to the cement floor 4. This structure allows the through bolt 507 to secure the pressure ring 506, the insulation board 2, and the cement floor 4. The plate 4 and the clamping plate 503 inside the base layer 3 are firmly clamped together. In order to achieve stable installation of the base 501, a base groove 502 is opened on the top of the cement floor 4. The base 501 is adapted to the shape and is clamped inside the base groove 502. The upper surface of the base 501 is flush with the upper surface of the cement floor 4. In order to further enhance the connection strength between the base 501 and the cement floor 4, the edge fixing mechanism 5 also includes a fixing anchor 508.

[0032] As a preferred embodiment, please refer to Figure 4The surface fixing mechanism 6 includes a fixing nail 601, which includes a rod and a nail head 604 fixedly connected to the left end of the rod. The nail head 604 has a large contact area and is used to abut against and press the outer surface of the insulation board 2.

[0033] As a preferred embodiment, please refer to Figure 4 In order to enhance the fixing effect of the fixing nail 601, the shank of the fixing nail 601 has an annular gap 602 near the nail head 604, and the annular gap 602 forms a receiving space with the inner wall of the insulation board 2.

[0034] As a further preferred embodiment, please refer to Figure 2 An adhesive block 603 is filled inside the annular gap 602. The adhesive block 603 is injected during installation and cures inside the annular gap 602. The adhesive block 603 is bonded to the material of the insulation board 2, thereby forming an auxiliary fixing surface between the nail head 604 and the insulation board 2.

[0035] As a preferred embodiment, please refer to Figure 1 In order to protect the internal structure and achieve the aesthetics of the building facade, the wall insulation layer anti-detachment fixing structure also includes a decorative layer 1, which covers the outer wall of the insulation board 2 and the outer side of the surface fixing mechanism 6.

[0036] Working principle: During the construction and installation of the wall, a base groove 502 is first opened at the top connection junction of the cement floor 4. The base 501 of the edge fixing mechanism 5 is adapted to the shape and locked inside the base groove 502. The base 501 is vertically anchored inside the cement floor 4 by fixing anchor nails 508. At this time, the clamping plate 503 fixedly connected to the right end of the base 501 is embedded in the base layer 3 to be installed. When the insulation board 2 is installed in place, the pressure ring 506 fixedly connected to the left end of the base 501 is tightly attached to and presses the outer wall of the insulation board 2. Then, the through bolt 507 is screwed into the inner groove 505 of the base 501. The through bolt 507 passes through the inner wall of the pressure ring 506, the insulation board 2 and part of the cement floor 4 in sequence. The tail of the through bolt 507 finally engages with the screw hole 504 on the clamping plate 503 embedded in the base layer 3 and is tightened. Through the locking force of the through bolt 507, the outer pressure ring 506 and the inner clamping plate 503 are firmly clamped together, so that the insulation board 2, the base layer 3 and the cement floor 4 are locked into a high-strength three-dimensional fixed structure at the corners, thereby solving the problem of warping and falling off due to stress concentration at the corners. The surface fixing mechanism 6 is used to assist in fixing a large area of ​​the insulation board 2. Before installing the fixing nail 601, adhesive is filled into the annular gap 602 of the fixing nail 601 near the nail head 604. Then, the fixing nail 601 is horizontally inserted through the insulation board 2 and driven into the base layer 3. The nail head 604 of the fixing nail 601 abuts and presses against the outer surface of the insulation board 2. After the adhesive filled in the annular gap 602 is cured, it forms an adhesive block 603. The adhesive block 603 forms an auxiliary fixing surface between the fixing nail 601 and the insulation board 2. This structure greatly increases the holding area and tension of the nail head 604 on the insulation board 2 by utilizing the adhesive force of the adhesive block 603, effectively preventing the nail head 604 from pulling through the soft insulation board 2.
