Description

Technical Field

[0001] The utility model relates to the technical field of curtain wall joints, in particular to a filling structure for the joints of an aluminum plate curtain wall. Background Technique

[0002] The aluminum plate curtain wall combines architectural and aesthetic structural designs and perfectly demonstrates various functions of the aluminum plate. It has a light self-weight, only one-fifth of that of marble and one-third of that of a glass curtain wall, greatly reducing the load on the building structure and foundation. Moreover, it has a low maintenance cost and a high performance-price ratio.

[0003] There will be installation gaps between the splicing panels of the existing aluminum plate curtain wall, and rainwater will enter the interior of the splicing panels from the installation gaps, causing the installation keel to rust and corrode. To meet the requirement of the waterproof performance of the curtain wall, sealant is usually used to fill the installation gaps for sealing. However, the sealant exposed outdoors for a long time will gradually oxidize and dry. Under the change of outdoor temperature, the thermal expansion and contraction of the splicing panels will squeeze the sealant, causing the sealant to crack and thus the sealant waterproof effect to fail.

The lower side of the support frame 4 is provided with a positioning arc piece 6 extending toward the plug-in slot. The positioning arc piece 6 is configured as an arc-shaped piece bent upward. The positioning arc piece 6 and the clamping arc piece 3 are mutually clamped. The thickness of the positioning arc piece 6 is less than the height of the plug-in slot. The upper and lower widths of the positioning arc piece 6 are greater than the height of the plug-in slot. When the positioning arc piece 6 extends into the plug-in slot, under the extrusion of the clamping arc piece 3, the upper side of the positioning arc piece 6 will be clamped in the lower bending position of the clamping arc piece 3, and the positioning arc piece The end of 6 will abut against the bottom wall of the plug-in slot and maintain a certain elasticity. Through the elastic force of the positioning arc piece 6, the positioning arc piece 6 is tightly abutted and clamped on the clamping arc piece 3 to form an installation positioning. The support frame 4 is provided with a contact piece 7, and an elastic clamping groove is provided between the contact piece 7 and the positioning arc piece 6. The upper and lower height difference of the clamping arc piece 3 is greater than the height of the elastic clamping groove. When the clamping arc piece 3 is inserted into the elastic clamping groove, the end of the clamping arc piece 3 abuts against the contact piece 7, and the lower bend of the clamping arc piece 3 is at the upper bend of the positioning arc piece 6. They abut against each other and clamp to form positioning, so that the support frame 4 can be fixed on the base beam 1.

[0026] There is an installation gap between two adjacent splicing panels 5. The support block 2 is centrally arranged in the installation gap. A positioning groove is formed at the front end of the support block 2, and a locking groove is formed in the inner wall of the positioning groove. The locking groove includes a horizontally clamped surface and an inclined sliding surface connected end to end. The fastening assembly includes a positioning middle plate 8 and a bent fastening plate 9. Locking pieces 10 are symmetrically arranged at the front end of the positioning middle plate 8. A buffer gap 11 is arranged between the two locking pieces 10. A locking protrusion that is in concave-convex fit with the locking groove is arranged on the outer side of the locking piece 10. The locking protrusion is clamped in the locking groove. The cross section of the bent fastening plate 9 is set to be V-shaped, and both end parts of the bent fastening plate 9 are abutted and fastened on the splicing panel 5.

[0027] Slots are formed at the front ends of the two locking pieces 10, and a supporting arc piece 12 is connected in the slots on both sides. The middle part of the supporting arc piece 12 bulges downward, and the middle part of the supporting arc piece 12 abuts against the inner wall of the positioning groove. After the supporting arc piece 12 abuts against the inner wall of the positioning groove and is pressed, the end parts inserted into the slots on both sides will expand outwards, and will abut against the locking piece 10 to deform it to both sides, pushing the supporting locking piece 10 to abut against the locking groove to complete the locking.

[0028] Sliding sleeves 13 are symmetrically arranged on both sides of the positioning middle plate 8. A guiding support plate 14 is slidably connected to the sliding sleeve 13.

The deformation assembly includes a deformation chute 15 arranged on the inner side of the guiding support plate 14, a guiding column 16 fixed on the bent fastening plate 9, a deformation sliding rod 17 rotatably connected to the guiding column 16, deformation ball blocks 18 arranged at both ends of the deformation sliding rod 17, and a deformation torsion spring 19 fixed at both ends on the bent fastening plate 9 and the deformation sliding rod 17 respectively. The deformation ball block 18 is slidably connected in the deformation chute 15.

[0029] Working process:

[0030] In the present utility model, first, the base beam slab 1 is fixed on the installation keel by bolts, and the splicing panel 5 is fixed on the support frame 4 to form a panel plug-in. The panel plug-in is horizontally slid and inserted on the base beam slab 1. The positioning arc piece 6 on the support frame 4 and the clamping arc piece 3 on the base beam slab 1 are mutually extruded and deformed and clamped together to form a positioning. The splicing panel 5 is fixed on the base beam slab 1. After assembly, an installation gap is formed between two adjacent splicing panels 5. Among them, the support block 2 on the base beam slab 1 is arranged at the center position of the installation gap. Then, the fastening component is inserted into the installation gap. During the insertion process, the locking piece 10 and the locking groove are mutually extruded, and the buffer gap 11 inside the extrusion shrinks. The locking piece 10 slides and contracts and slides down to the bottom of the locking groove. The middle convex part of the support arc piece 12, after being pressed against the inner wall of the positioning groove, the ends inserted into the slot on both sides will expand outwards and push the locking piece 10 to deform towards both sides, pushing the support locking piece 10 to abut against the locking groove to complete the locking, so that the fastening component can be fixed on the installation gap. Among them, the bent fastening plate 9 is buckled on the front sides of the two splicing panels 5. During this process, the bent fastening plate 9 is deformed after being pressed and keeps a certain elasticity to abut against the splicing panel 5, so as to achieve the sealing effect and prevent rainwater from entering the installation gap;

[0031] During the installation process, under the elastic action of the deformation torsion spring 19, the guiding support plates 14 on both sides are abutted between the two splicing panels 5 under the support of the deformation sliding rod 17. When the splicing panels 5 expand and contract due to heat, the distance between the installation gaps between the two splicing panels 5 on both sides becomes smaller, causing the guiding support plates 14 to horizontally slide on the sliding sleeve 13, and the deformation sliding groove 15 extrudes the deformation ball block 18, causing the deformation sliding rod 17 to rotate around the guiding column 16. During this process, the deformation torsion spring 19 contracts and maintains a certain rotational torque, so that the guiding support plates 14 always abut against the splicing panels 5, keeping the fastening component centered and installed in the installation gap.

[0032] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
