Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a reinforcement device and method for curtain wall panel hooks. Background Technology

[0002] Currently, in the construction of building curtain walls, the fixed installation of curtain wall panels is one of the core processes, and the reliability of its connection directly affects the overall structural safety, operational stability, and service life of the curtain wall. The connection between curtain wall panels and the main building structure typically adopts a hook-and-mount structure. This structure mainly includes connecting brackets, hooks, and curtain wall panels. The connecting brackets need to be pre-embedded or welded to the main building structure, while the hooks are fixedly connected to the curtain wall panels. By inserting the hooks into the grooves of the connecting brackets, a detachable connection between the curtain wall panels and the main structure is achieved, thus completing the fixed installation of the curtain wall panels.

[0003] Because the curtain wall panels need to meet wind resistance, load-bearing and positioning requirements after installation, the groove of the connecting bracket needs to strictly limit the movement space of the curtain wall panels. Therefore, the size and space design of the groove is limited, and at the same time, it puts forward extremely high requirements for the installation accuracy of the connecting bracket. The pre-embedded or welded position, elevation and level of the bracket must be strictly controlled to ensure that the hook can fall accurately into the groove and achieve a reliable connection.

[0004] However, in actual construction, due to various factors such as the skill level of construction personnel, the precision of construction equipment, the on-site construction environment and construction technology, the connection bracket is prone to installation deviation during the pre-embedding or welding process. This results in the groove position and angle of the connection bracket not being accurately matched with the hook on the curtain wall panel, and the hook not being able to fall smoothly into the groove of the bracket, thus preventing the normal installation and placement of the curtain wall panel.

[0005] When the hook and the mounting bracket groove cannot be installed within the allowable deviation range, the existing technology usually adopts two rectification methods: the first is to remove the pre-embedded or welded connecting bracket and re-embed or weld it to adjust the position of the bracket to meet the requirements; the second is to cut and modify the hook on the curtain wall panel, and adjust the size or angle of the hook to fit the mounting bracket groove, so as to achieve the installation position.

[0006] Both of the above rectification methods have obvious drawbacks: For the first rectification method, after removing the bracket, it is necessary to re-embed / weld, position and calibrate, etc., which involves a large amount of work, complicated construction procedures, and will delay the construction progress and increase construction costs. At the same time, repeated pre-embedding / welding operations may also cause additional damage to the main structure of the building. For the second rectification method, after cutting and modifying the hook, the structural integrity of the hook is destroyed, and its load-bearing capacity and structural strength will be greatly reduced. Therefore, it is necessary to take reinforcement measures for the cut hook and the matching bracket to ensure the load-bearing requirements and connection stability of the curtain wall panel and avoid safety problems such as falling off and loosening during subsequent use.

[0007] Currently, there is a lack of unified standards and specifications in the industry for reinforcement measures after hook cutting and for adjusting the installation deviations of brackets and hooks. Different construction units use different reinforcement processes, materials and adjustment methods, resulting in inconsistent reinforcement effects. This makes it difficult to effectively compensate for the structural damage caused by hook cutting, and it is difficult to meet the load-bearing requirements of curtain wall panels for long-term use. As a result, there is a risk of uneven load-bearing and stress imbalance of curtain wall panels, which may lead to safety hazards such as curtain wall panels falling off in severe cases, threatening the safety of building use and personal safety.

Detailed Implementation

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Reference Figure 1 and Figure 2 This invention discloses a reinforcement device 1 for curtain wall panel hooks, comprising a snap-fit ​​part 10, a bending part 20, and a wrapping part 30. The snap-fit ​​part 10, the bending part 20, and the wrapping part 30 are sequentially connected to form a U-shape. The connecting groove formed by the snap-fit ​​part 10, the bending part 20, and the wrapping part 30 is adapted to the cutting position of the hook 2 to be reinforced, and the cutting position of the hook 2 to be reinforced is inserted into the connecting groove. The bottom surface of the snap-fit ​​part 10 has a latch 11, which is adapted to the groove of the bracket 3 on the main building structure. The latch 11 and the groove cooperate to make the snap-fit ​​part... 10 is connected to the bracket 3; on the one hand, the U-shaped snap-fit ​​part 10, the bending part 20 and the wrapping part 30 are arranged to form a connecting groove that is adapted to the cutting position of the hook to be reinforced 2, which can form an all-round wrapping limit for the hook after cutting, avoiding the problem of uneven force and loosening due to damage to the structural integrity after the hook is cut; on the other hand, the snap-fit ​​part 10 is precisely matched with the groove of the bracket 3 through the snap-fit ​​11, realizing a stable connection between the reinforcement device 1 and the main structure of the building, effectively transferring the load borne by the hook, and improving the load-bearing capacity and structural stability of the hook of the curtain wall panel 4.

[0031] Specifically, the bottom of the bent portion 20 is higher than the bottom of the snap-fit ​​portion 10.

[0032] Furthermore, in this embodiment, a locking platform 12 is provided on the inner side of the end of the locking part 10 away from the bending part 20. The locking platform 12 extends inward, and the locking platform 12 and the inner sidewall of the locking part 10 together form a locking groove 13. The locking groove 13 is adapted to the protrusion 21 of the hook to be reinforced, and the protrusion 21 is locked in the locking groove 13. By setting the locking groove 13, the locking groove 13 and the protrusion 21 of the hook to be reinforced are precisely locked, which further improves the tightness of the connection between the reinforcing device 1 and the hook to be reinforced, and prevents relative displacement between the two. The cooperation between the locking groove 13 and the protrusion 21 can form a double limit in the longitudinal and transverse directions for the hook to be reinforced, disperse the stress concentration at the cutting position of the hook to be reinforced, avoid the hook to be reinforced from breaking due to excessive local stress, and at the same time enhance the installation firmness of the reinforcing device 1, ensuring the long-term stability of the reinforcement effect.

[0033] Furthermore, in this embodiment, triangular protrusions 31 are provided on the inner walls of the snap-fit ​​portion 10, the bending portion 20, and the wrapping portion 30. The triangular protrusions 31 are used to contact the outer wall of the snap-fit ​​plate of the hook to be reinforced 2. By providing the triangular protrusions 31, the contact friction between the reinforcing device 1 and the snap-fit ​​plate of the hook to be reinforced 2 is increased, preventing slippage between the two and improving the stability of the connection. In addition, the triangular protrusions 31 can form point contact support, which can ensure tight contact and avoid installation jamming caused by large-area contact. At the same time, it can disperse the force on the hook cutting position, reduce local stress concentration, further protect the hook structure, and extend its service life.

[0034] Specifically, in this embodiment, the inner wall of the snap-fit ​​part 10 is provided with two triangular protrusions 31, the inside of the bending part 20 is provided with one triangular protrusion 31, and the inner wall of the wrapping part 30 is provided with one triangular protrusion 31.

[0035] In order to improve the fit between the snap-fit ​​part 10 and the hook to be reinforced 2, an arc-shaped groove is provided inside the snap-fit ​​part 10, which is adapted to the arc-shaped protrusion of the hook to be reinforced 2.

[0036] Furthermore, in this embodiment, a limiting groove 14 is provided on the top surface of the snap-fit ​​part 10. The limiting groove 14 is adapted to the top limiting steel plate 302 connected to the side steel plate 301 of the bracket 3. The end of the top limiting steel plate 302 away from the side steel plate 301 is inserted into the limiting groove 14. By cooperating with the limiting groove 14, the top limiting of the reinforcing device 1 can be formed, restricting the longitudinal displacement of the reinforcing device 1 and avoiding the hidden dangers of upward loosening or falling off during use. The top limiting steel plate 302 can connect the reinforcing device 1, the bracket 3 and the side steel plate 301 into a whole, realize the force distribution and transmission, improve the integrity and stability of the entire curtain wall hook connection structure, and further enhance the reinforcement effect.

[0037] In this embodiment, the snap-fit ​​portion 10, the bending portion 20, and the wrapping portion 30 are all made of aluminum alloy. Of course, the snap-fit ​​portion 10, the bending portion 20, and the wrapping portion 30 can also be made of other metal materials.

[0038] In this embodiment, the snap-fit ​​part 10, the bending part 20, and the wrapping part 30 are integrally formed. This arrangement eliminates the connection gaps between the components, improves the overall structural strength and rigidity of the reinforcing device 1, and avoids reinforcement failure caused by loose component connections. In addition, the integrally formed structure can reduce processing steps and assembly steps, reduce processing and installation costs, and at the same time ensure the dimensional accuracy of each component, ensuring that the connecting groove, snap-fit ​​11 and other structures are precisely matched with the hook 2 and the bracket 3 to be reinforced, improving installation efficiency and installation quality. Moreover, the structure has good overall integrity and more uniform stress distribution, further enhancing the reinforcement effect.

[0039] Continue to refer to Figures 3 to 9 Another embodiment of the present invention provides a reinforcement method using the reinforcement device 1 for hooking the curtain wall panel 4 as described above, comprising the following steps: S101. The gap between the cut-out reinforcement hook 2 and the light material is filled and fixed with weather-resistant adhesive. S102. The position of the bayonet 11 of the reinforcement device 1 is checked after the wire laying is completed, and the reinforcement device 1 is processed according to the wire laying dimensions; S103. Install the reinforcing device 1 at the cutting position of the hook 2 to be reinforced, and engage it with the bracket 3. S104. Limiting steel plates are welded on both sides of the groove of the bracket 3. S105. Lateral steel plates 301 are provided on both sides of the hanger 3. S106. A top limiting steel plate 302 is provided between the reinforcing device 1 and the lateral steel plate 301; S107, Reinforcement device 1 is installed.

[0040] On the one hand, by tightening and fixing the gap, problems such as loose connection and water ingress caused by the gap can be avoided, thus improving the structural durability. On the other hand, by checking the layout and processing precisely, it is ensured that the reinforcement device 1 is accurately matched with the hook and bracket 3, avoiding reinforcement failure caused by installation deviation. In addition, the step-by-step installation of the limiting steel plate, the side steel plate 301 and the top limiting steel plate 302 can form multi-directional limiting for the reinforcement device 1 and the hook, connecting the components into a whole, realizing the uniform transmission of force, effectively dispersing the stress at the hook cutting position, and significantly improving the structural stability and load-bearing capacity of the curtain wall hook.

[0041] Specifically, before filling the gap between the cut-out hook 2 and the light-cut material in S101 and fixing it with weather-resistant adhesive, the process also includes: conducting a pull-out force test on the reinforcing device 1. The reinforcing device 1 can be implemented only if it does not break under a pull force of 30KN. All welds on site are of grade 3 or above.

[0042] S101 involves filling the gap between the cut-out hook 2 to be reinforced and the smooth surface, and fixing it with weather-resistant adhesive. This includes: when the gap between the cut-out hook 2 to be reinforced and the smooth surface is greater than 5mm, a combination of steel plate and rubber pad is used to fill it tightly; when the gap between the cut-out hook 2 to be reinforced and the smooth surface is less than or equal to 5mm, a rubber pad is used to fill it tightly, and weather-resistant adhesive is applied to the surface of the rubber pad. This setting allows for differentiated filling methods for gaps of different sizes. When the gap is greater than 5mm, a combination of steel plate and rubber pad is used to fill it tightly, ensuring the firmness of the filling and the density of the filling, and preventing the filling structure from loosening due to excessive gaps. In addition, the rubber pad, in conjunction with the weather-resistant adhesive, can act as a buffer, reducing hard contact wear between components, and enhancing the sealing performance, preventing rainwater, dust, and other impurities from entering the gap and preventing the hook and bracket 3 from rusting. At the same time, the weather-resistant adhesive has good resistance to high and low temperatures and aging, ensuring the long-term stability of the filling structure and further improving the durability of the reinforcement. Further, in this embodiment, S103, installing the reinforcing device 1 at the cutting position of the hook 2 to be reinforced and engaging it with the bracket 3 includes: S1031. Move the side-rotating reinforcement device 1 downward from the gap in the main building structure to the preset position; S1032. Rotate the preset angle to directly above the hook 2 to be reinforced, and insert it vertically downwards into the groove of the bracket 3.

[0043] Specifically, the reinforcing device 1 is turned to the side and moved downward from the gap in the main building structure to a preset position. The reinforcing device 1 is rotated 90 degrees to be directly above the hook 2 to be reinforced, and then vertically inserted into the groove of the bracket 3. The depth of the reinforcing device 1 inserted into the bracket 3 is 15mm. A 1mm thick flexible rubber pad 304 is used to isolate the reinforcing device 1 and the bracket 3.

[0044] Furthermore, in this embodiment, S102, verifying the position of the bayonet 11 of the reinforcement device 1 after laying out the wire, and processing the reinforcement device 1 according to the laying-out dimensions, includes: verifying the position of the bayonet 11 of the reinforcement device 1 after laying out the wire, ensuring that the bayonet 11 of the reinforcement device 1 is accurate and not subject to hot cutting on site, and processing the reinforcement device 1 according to the laying-out dimensions, wherein the depth and width of the bayonet 11 are measured according to the actual cutting conditions on site.

[0045] Furthermore, in this embodiment, after setting the top limiting steel plate 302 between the reinforcing device 1 and the lateral steel plate 301 in S106, before the reinforcing device 1 is installed in S107, the method further includes setting an anti-jump steel plate 303 between the lateral steel plate 301, the top limiting steel plate 302 and the snap-fit ​​portion 10 of the reinforcing device 1.

[0046] Specifically, the first end of the anti-jump steel plate 303 is connected to the side steel plate 301, the second end of the anti-jump steel plate 303 is connected to the top limiting steel plate 302, and the bottom surface of the anti-jump steel plate 303 presses against the top surface of the snap-fit ​​part 10.

[0047] It should be noted that the first and second ends of the anti-jump steel plate 303 are set adjacent to each other.

[0048] Furthermore, in this embodiment, S106, setting a top limiting steel plate 302 between the reinforcing device 1 and the side steel plate 301 includes: one end of the top limiting steel plate 302 is welded to the side steel plate 301, and the other end of the top limiting steel plate 302 is inserted into the limiting groove 14.

[0049] The reinforcement device 1 and reinforcement method for curtain wall panel hooks provided in this application include a snap-fit ​​part 10, a bending part 20, and a wrapping part 30. The snap-fit ​​part 10, the bending part 20, and the wrapping part 30 are sequentially connected to form a U-shape. The connecting groove formed by the snap-fit ​​part 10, the bending part 20, and the wrapping part 30 is adapted to the cutting position of the hook 2 to be reinforced. The cutting position of the hook 2 to be reinforced is inserted into the connecting groove. The bottom surface of the snap-fit ​​part 10 has a latch 11, which is adapted to the groove of the bracket 3 on the main structure of the building. The latch 11 and the groove cooperate to make the snap-fit ​​part 10 and the bracket... 3. Connection; Reinforcement process: Tighten the gap between the cut hook to be reinforced 2 and the smooth surface - lay out the lines - install the reinforcement device 1 - install the limiting steel plate - install the side steel plate 301 - install the top limiting steel plate 302 - installation complete; The U-shaped snap-fit ​​part 10, bending part 20 and wrapping part 30 are arranged to form a connecting groove that fits the cutting position of the hook to be reinforced 2.
