[0033] The utility model provides a unit curtain wall.

[0034] Please refer to Figures 1 to 5 In an embodiment of the present application, the unit curtain wall 100 comprises:

[0035] The unit plate block 1 comprises a bottom cross beam 11 and a plurality of sub-blocks 12, the plurality of sub-blocks 12 are mutually inserted, and part of the plurality of sub-blocks 12 are installed above the bottom cross beam 11. The bottom cross beam 11 is provided with a clamping boss 111;

[0036] The connecting piece 2 is arranged on one side of the bottom cross beam 11, and the connecting piece 2 is clamped with the bottom cross beam 11 at the clamping boss 111; and

[0037] The horizontal decorative strip 3 is clamped on the outer side of the connecting piece 2 and protrudes and extends towards the outer side of the sub-block 12.

[0038] The technical scheme of the utility model discloses a clamping of the connecting piece 2 and the clamping boss 111 on the unit board 1, and the clamping structure on the clamping boss 111 and the connecting piece 2 is matched with each other, so that the connecting piece 2 can be accurately positioned at the predetermined position of the bottom cross beam 11 during installation, compared with the traditional bolt connection mode, the connecting piece 2 can be assembled without complex tools and a plurality of bolt connection points, and meanwhile, the connecting piece 2 and the horizontal decorative strip 3 are also clamped and fixed, the horizontal decorative strip 3 can be clamped to the outer side of the connecting piece 2 easily, and the installation difficulty and cost are reduced without additional welding or bonding procedures.

[0039] Specifically, the bottom cross beam 11 can be a cuboid or a cube, and the length, width and height thereof are determined according to the size requirement and structural strength requirement of the unit curtain wall 100. The upper surface of the bottom cross beam 11 is provided with a clamping boss 111, and the clamping boss 111 can be in a trapezoidal shape, which is conducive to the clamping and clamping of the connecting piece 2. During the clamping process, the inclined edge of the trapezoidal shape can play a guiding role, so that the connecting piece 2 is more easily positioned to the correct clamping position. The connecting piece 2 can be in an L shape as a whole, one side of which is used for clamping with the bottom cross beam 11, and the inner side of the side is provided with a clamping groove matched with the clamping boss 111, and the clamping groove is also in a trapezoidal shape and is complementary to the shape of the clamping boss 111. The other side is used for clamping with the horizontal decorative strip 3, and the outer side of the side can be provided with a protruding clamping strip, and the clamping strip is in a rectangular shape and is used for cooperating with the clamping groove on the horizontal decorative strip 3. The horizontal decorative strip 3 can be in a flat strip shape, and is provided with a clamping groove or a clamping hole on the side clamped with the connecting piece 2 and matched with the clamping strip on the connecting piece 2. During installation, the clamping groove or the clamping hole of the horizontal decorative strip 3 is aligned with the clamping strip on the connecting piece 2, and then the decorative strip is pushed along the direction of the clamping strip until the clamping groove or the clamping hole completely covers the clamping strip, so that the clamping is realized. In this way, the horizontal decorative strip 3 is firmly installed on the outer side of the connecting piece 2 and can protrude and extend towards the outer side of the sub-block 12, so as to decorate the unit curtain wall 100.

[0040] In the embodiment of the utility model, please refer to Figure 3 and Figure 4The unit curtain wall 100 further comprises a limiting screw 4 arranged on the connecting piece 2 and connecting the connecting piece 2 and the clamping boss 111. The limiting screw 4 can be a common cylindrical head hexagonal screw. During installation, after the connecting piece 2 is clamped to the clamping boss 111 of the bottom cross beam 11, the limiting screw 4 is screwed into the threaded hole arranged in advance on the connecting piece 2, so that the limiting screw 4 penetrates through the connecting piece 2 and contacts the clamping boss 111. The arrangement of the limiting screw 4 greatly enhances the connection stability between the connecting piece 2 and the unit panel 1 (the bottom cross beam 11). On the basis of the original clamping structure, the limiting screw 4 plays an auxiliary fixing role. For example, when subjected to external forces such as wind load or earthquake for a long time, only the clamping structure may have a slight displacement or looseness, while the limiting screw 4 can resist such external forces to ensure the firm connection between the connecting piece 2 and the bottom cross beam 11, thereby improving the structural safety of the entire unit curtain wall 100.

[0041] In the embodiment of the utility model, please refer to Figure 3 and Figure 4 The unit curtain wall 100 further comprises a limiting bolt 5 arranged on the connecting piece 2 and spaced apart from the limiting screw 4, and the limiting bolt 5 connects the horizontal decorative strip 3 and the connecting piece 2 through a nut. The limiting bolt 5 can adopt a standard hexagonal head bolt. During installation, the limiting bolt 5 is first penetrated through the bolt hole arranged in advance on the connecting piece 2, and then the corresponding mounting hole on the horizontal decorative strip 3 is aligned with the limiting bolt 5. Then, the nut is screwed onto the limiting bolt 5 and gradually tightened by rotating the nut. During the tightening process, the distance between the nut and the connecting piece 2 gradually decreases, thereby tightly fixing the horizontal decorative strip 3 on the connecting piece 2. The cooperation of the limiting bolt 5 and the nut makes the connection between the horizontal decorative strip 3 and the connecting piece 2 more firm, and compared with only relying on the clamping structure, the limiting bolt 5 provides additional fixing force. For example, when subjected to external force impact (such as strong wind carrying foreign matter impact), the clamping structure may be affected and cause the decorative strip to loosen, while the limiting bolt 5 can ensure that the decorative strip is firmly connected to the connecting piece 2, maintaining the appearance integrity of the unit curtain wall 100. It should be noted that the number of limiting bolts 5 and limiting screws 4 is not specifically limited and can be arranged in one row or two rows according to actual needs.

[0042] In the embodiment of the utility model, the limit hole is long circular, the short axis diameter is 6mm, the long axis direction is along the length direction of the transverse decorative strip 3, and the long axis length is 10mm, which can provide enough space to adjust the gap left and right of the transverse decorative strip 3. When installing the transverse decorative strip 3, the limit bolt 5 is passed through the limit hole, and then the nut is screwed. When the gap left and right of the transverse decorative strip 3 needs to be adjusted, the transverse decorative strip 3 can be moved left and right within a certain range because the limit hole is long circular and is limitedly matched with the limit bolt 5. For example, if it is found that the gap between the transverse decorative strip 3 and the adjacent part is wider on the left and narrower on the right, the transverse decorative strip 3 can be moved to the left, at this time, the limit bolt 5 slides in the limit hole, until the appropriate gap width is reached, and then the nut is tightened to fix the position of the transverse decorative strip 3.

[0043] In the embodiment of the utility model, please refer to Figures 1 to 3 The decorative strip buckle plate 6 is buckled on the surface of the transverse decorative strip 3 to shield the limit bolt 5. The decorative strip buckle plate 6 is in sheet structure, and the shape is matched with the surface shape of the transverse decorative strip 3. One side edge of the decorative strip buckle plate 6 is provided with a downward bending part for buckling on the edge of the transverse decorative strip 3, and the other side edge is a smooth bevel to realize the beautiful transition. The middle part of the decorative strip buckle plate 6 can have some reinforcing rib structures, and the reinforcing rib is a small raised line to increase the strength of the decorative strip buckle plate 6. The main function of the decorative strip buckle plate 6 is to shield the limit bolt 5, so that the appearance of the unit type curtain wall 100 is more neat and beautiful; and the limit bolt 5 can be protected to a certain extent. It can prevent external factors (such as rainwater, dust, corrosive gas, etc.) from directly contacting the limit bolt 5, and reduce the occurrence of bolt rusting, corrosion and the like.

[0044] In the embodiment of the utility model, the connecting piece 2 is provided with an elastic buckle (not shown in the figure), the elastic buckle is matched with the clamping boss 111, and the inner side of the elastic buckle is provided with a wear-resistant pad. The elastic buckle is in whole "U" shape structure, which is made of elastic metal material, for example, stainless steel. The wear-resistant pad can be a silica gel pad or a polyurethane elastomer. When the connecting piece 2 is clamped with the clamping boss 111 of the bottom cross beam 11, the opening end of the elastic buckle is first aligned with the clamping boss 111, and then the clamping boss 111 extrudes the two sides of the elastic buckle as the connecting piece 2 is pressed down, so that the two sides expand outward. Because the elastic buckle has elasticity, when the clamping boss 111 passes the widest part of the buckle, the buckle restores to the original state under the action of its own elasticity, tightly clamping the clamping boss 111. The wear-resistant pad contacts the clamping boss 111 in this process, and plays a buffering and wear-resistant role.

[0045] In the embodiment of the utility model, please refer toFigures 1 to 3 The unit curtain wall 100 further comprises a decorative strip rubber strip 7, which is embedded at the connection between the bottom cross beam 11 and the transverse decorative strip 3 and is arranged along the length direction of the transverse decorative strip 3.

When the unit curtain wall 100 is installed, after the connection between the transverse decorative strip 3 and the bottom cross beam 11 is ready, the decorative strip rubber strip 7 is slowly embedded into the connection along the length direction of the transverse decorative strip 3 from one end. Since the rubber strip has a certain flexibility, it can smoothly fill the gap between the bottom cross beam 11 and the transverse decorative strip 3. During the embedding process, the anti-skid lines of the rubber strip help it to be fixed in place better and not to slide easily.

[0046] In the embodiments of the present application, please refer to Figure 1 and Figure 3 The unit curtain wall 100 further comprises a waterproof rubber strip 8, which is arranged at the connection between two adjacent sub-blocks 12 and is arranged along the width direction of the unit panel 1. The waterproof rubber strip 8 is made of ethylene propylene diene rubber (EPDM) material, and when the unit curtain wall 100 is installed, when the two adjacent sub-blocks 12 are spliced, the waterproof rubber strip 8 is placed at the connecting edge of one of the sub-blocks 12 in advance, so that the sealing rib of the rubber strip faces the other sub-block 12. Then the two sub-blocks 12 are butt jointed, and during the butt joint process, the connecting edge of the other sub-block 12 extrudes the waterproof rubber strip 8, so that the rubber strip deforms to a certain extent, the sealing rib is compressed, and thus the rubber strip is tightly filled in the gap between the two sub-blocks 12, forming a sealed defense line along the width direction of the unit panel 1, which can prevent rainwater from penetrating into the unit curtain wall 100 from the gap between the sub-blocks 12.

[0047] In the embodiments of the present application, please refer to Figure 1 and Figure 6 The unit panel 1 further comprises a column 13, and the plurality of sub-blocks 12 are connected through the column 13. The column 13 is a long strip structure made of aluminum alloy, and its cross section is rectangular.

During the installation of the unit curtain wall 100, when the plurality of sub-blocks 12 are to be connected, the connecting parts of the sub-blocks 12 are aligned with the insertion grooves on the column 13. Then the sub-blocks 12 are slowly inserted into the insertion grooves. Since the size of the insertion grooves matches the connecting parts of the sub-blocks 12, the sub-blocks 12 can be stably inserted into the column 13. During the insertion process, it is ensured that the sub-blocks 12 are completely inserted into the insertion grooves, so that a tight connection is formed between the sub-blocks 12 and the column 13. The column 13 provides a unified support structure for the plurality of sub-blocks 12, so that the connection between the sub-blocks 12 is more stable.

[0048] In the embodiment of the utility model, the sub - block 12 includes glass and metal frame, glass is inlayed in metal frame, metal frame is equipped with sealing gum with the junction of stand 13.
