Description

Technical Field

[0001] This invention relates to a curtain wall structure, and more particularly to a hollow terracotta panel curtain wall structure. Background Technology

[0002] Terracotta panel curtain walls, as a type of building exterior wall structure, can be installed with terracotta panels of different shapes to meet the needs of the building's exterior and interior. However, existing terracotta panel curtain walls have hollow through-holes on the sides of the terracotta panels. The suspension installation of the terracotta panels typically involves prefabricating T-slots on the back of the hollow terracotta panels, installing multiple hooks, and then hanging the terracotta panels onto the curtain wall support components. This connection method has problems such as high precision requirements for the T-slots and uneven stress distribution at the mounting points. This poses a risk of collision between the T-slots, hooks, and terracotta panels under wind loads, potentially causing the terracotta panels to crack. Summary of the Invention

[0003] The purpose of this invention is to provide a hollow terracotta panel curtain wall structure, and the technical problem to be solved is to improve the load-bearing performance and safety of terracotta panel curtain walls.

[0004] To solve the above problems, the present invention adopts the following technical solution: a hollow terracotta panel curtain wall structure, comprising terracotta panels, which are hung on the columns of the building's exterior wall via a hanging system. The terracotta panels have hollow cavities spaced at equal intervals along the terracotta panels. The hanging system includes U-shaped clips with through grooves, hangers, and hanger fixing seats. The U-shaped clips are disposed in at least two through cavities on the terracotta panels. The hangers are secured by bolts passing through the back of the terracotta panels and the clip holes on the U-shaped clips, and then by nuts disposed in the through grooves of the U-shaped clips. A threaded connection is used to connect and fix the hanger to the terracotta panel. The hanger fixing seat is L-shaped and includes a horizontal part and a vertical part. The horizontal part is fixed to the curtain wall beam by a bolt assembly. The vertical part is opposite to the terracotta panel. An extension part is provided on the vertical part, extending away from the end of the terracotta panel. The hanger is hung on the extension part. The extension part has an extension screw hole, and the hanger has a hanger screw hole. When the hanger is hung on the extension part, the extension screw hole and the hanger screw hole are opposite to each other and are threadedly connected by a locking screw to fix the hanger to the hanger fixing seat.

[0005] Furthermore, bolt slots are provided on the curtain wall beams, which are set along the length of the curtain wall beams, and the bolts of the bolt assembly are engaged in the bolt slots.

[0006] Furthermore, the pendant is equipped with an adjusting screw, which rests on the extension.

[0007] Furthermore, a rubber gasket is placed between the pendant and the terracotta plate.

[0008] Furthermore, the pendant includes a terracotta plate connecting part opposite to the terracotta plate and a hook provided on the terracotta plate connecting part, the hook opening facing the pendant fixing seat, and the pendant screw hole is provided on the part of the hook body located above the extension.

[0009] Furthermore, an adhesive strip is provided on the end of the vertical part that is opposite to the connection part of the terracotta panel.

[0010] Furthermore, the curtain wall beam is fixed to the column by a beam fixing seat. The beam fixing seat is T-shaped and includes a column fixing part that is fixed to the column and a beam connecting part that is fixed to the curtain wall beam. On the two sides of the beam connecting part opposite to the curtain wall beam, there are beam inserts that are fixed by bolt assemblies. The two ends of the curtain wall beam are respectively inserted into the adjacent beam inserts and fastened by self-tapping screws.

[0011] Furthermore, the surface of the horizontal section away from the curtain wall beam is provided with raised and recessed teeth.

[0012] Furthermore, the terracotta slab is 35mm thick, has a water absorption rate of less than 0.8%, and a flexural strength of 2.23 N / mm². 2 .

[0013] Compared with existing technologies, this invention achieves the connection and fixation of the hanger and terracotta panel by setting U-shaped retaining strips in the hollow cavity of the terracotta panel, and by bolting through the hanger, the back of the terracotta panel, and the retaining strip through the retaining hole, and then connecting with the nut set in the through groove of the U-shaped retaining strip. Then, a hanger fixing seat is set on the curtain wall beam on the column and the hanger and the hanger fixing seat are connected and fixed by locking screws, thus realizing the installation of terracotta panel. By replacing the traditional T-slot with U-shaped retaining strips set in the original cavity of the terracotta panel and then connecting and fixing it with the hanger by bolt assembly, the maneuverability and installation flatness of the terracotta panel curtain wall can be greatly improved. Moreover, the use of U-shaped retaining strips can increase the contact area between the hanger system and the terracotta panel, making the terracotta panel more evenly stressed.

The hanging system includes a U-shaped clip 3 with a through groove 32, a hanger 4, and a hanger fixing seat 5. The U-shaped clip 3 is disposed in at least two cavities 2 on the terracotta panel 1. The hanger 3 is connected to the curtain wall by bolts 201 passing through the back of the terracotta panel 1 and the clip hole 31 on the U-shaped clip 3. The nut 200 in the through groove 32 of the U-shaped clip 3 is threaded to connect the hanger 4 to the terracotta panel 1. The hanger fixing seat 5 is L-shaped and includes a horizontal part 51 and a vertical part 52. The horizontal part 51 has a hole for bolts to pass through. The horizontal part 51 is fixed to the curtain wall beam 6 by a bolt assembly. The vertical part 52 is opposite to the terracotta panel 1. The vertical part 52 has an extension part 53 extending away from the end of the terracotta panel 1. The hanger 4 is hung on the extension part 53. The extension part 53 has an extension part screw hole 54. The hanger 4 has a hanger screw hole 41. When the hanger 4 is hung on the extension part 53, the extension part screw hole 54 and the hanger screw hole 41 are opposite to each other and are threadedly connected by a locking screw 8 to fix the hanger 4 to the hanger fixing seat 5.

[0020] The above structure replaces the traditional method of prefabricating T-slots on the back of hollow terracotta panels for hanging, greatly improving the load-bearing performance and installation flatness of the terracotta panel curtain wall.

[0021] like Figure 1 , Figure 2 and Figure 4As shown, the curtain wall beam 6 is fixed to the column 100 by the beam fixing seat 7. The curtain wall beam 6 is arranged in multiple rows according to the height of the building. The beams 6 in each row are spliced ​​together by the beam fixing seat 7. The curtain wall beam is made of aluminum alloy profile and has a through cavity inside. The beam fixing seat 7 is T-shaped and includes a column fixing part 71 that is fixed to the column 100 and a beam connecting part 72 that is connected to the curtain wall beam 6. The beam connecting part 72 is provided with through holes, and there are two through holes respectively set at the top and bottom. On the two sides of the beam connecting part 72 opposite to the curtain wall beam 6, there are beam inserts 12 that are fixed by bolt assembly through the through holes. The beam inserts 12 are provided with plug-in parts 121 that are adapted to the through cavity of the curtain wall beam. The two ends of the curtain wall beam 6 are respectively inserted into the plug-in parts 121 of the adjacent beam inserts 12 and the curtain wall beam 6 is connected and fastened to the plug-in parts 121 by self-tapping screws.

[0022] like Figure 2 and Figure 4 As shown, the insertion part 121 is provided with an insertion part screw hole 122. The axis of the insertion part screw hole 122 extends in a straight line from the terracotta plate 1 toward the column 100, so that the axis of the insertion part screw hole 122 is perpendicular to the back of the terracotta plate 1.

[0023] like Figure 2 As shown, a bolt slot 61 is provided on the curtain wall beam 6. The bolt slot 61 is provided along the length direction of the curtain wall beam 6, and the bolt of the bolt assembly is locked in the bolt slot 61. Specifically, the bolt slot 61 is provided on the end of the curtain wall beam 6 opposite to the horizontal part 51, preferably in the middle of that end.

[0024] like Figure 2 As shown, an adjusting screw 9 is provided on the hanger 4. The adjusting screw 9 is threadedly connected to the screw hole on the hanger 4, and the lower end of the adjusting screw 9 rests on the extension 53.

[0025] like Figure 2 As shown, in order to prevent the back of the hanger 4 from being rigidly connected to the terracotta plate 1, a rubber gasket 10 is provided between the hanger 4 and the terracotta plate 1 to achieve flexible contact. This avoids the danger of the terracotta plate breaking due to collision between the U-shaped clip, the hanger and the terracotta plate under wind load, and also reduces the risk of local stress concentration on the terracotta plate after the assembly of the traditional hanger system, which could lead to damage to the fixing point of the terracotta plate.

[0026] like Figure 2 and Figure 3 As shown, in this invention, the hanging component 4 includes a terracotta plate connecting portion 43 opposite to the terracotta plate 1 and a hook 44 disposed on the terracotta plate connecting portion 43. The terracotta plate connecting portion 43 has a through hole for the bolt 201 to pass through. The hook opening 42 of the hook 44 faces the hanging component fixing seat 5. The hanging component screw hole 41 and the adjusting screw 9 are both disposed on the hook body located above the extension portion 53 of the hook 44. Figure 2 It can be seen that the hook 44 is located in the middle of the terracotta plate connecting part 43, while the connection point of the bolt assembly used to connect with the terracotta plate and the U-shaped clip is located at the upper end of the terracotta plate connecting part 43 (i.e. above the hook 44).

[0027] like Figure 2 and Figure 3 As shown, an adhesive strip 11 is provided on the end of the vertical part 52 opposite to the terracotta board connecting part 43, so that there is no gap between the lower end of the terracotta board connecting part 43 and the vertical part 5; specifically, an adhesive strip groove 56 is provided on the side surface of the vertical part 52 opposite to the terracotta board 1 and near the extension part 53, and the adhesive strip 11 is stuck in the adhesive strip groove 56.

[0028] like Figure 1 As shown, a toothed pattern 55 is provided on the surface of the horizontal part 51 away from the curtain wall beam 6 to increase the anti-slip properties of the bolt assembly.

[0029] In one embodiment of the present invention, the clay slab 1 has a thickness of 35 mm, a water absorption rate of less than 0.8, and a bending strength of 2.23 N / mm². 2 The dimensions of the cavity 2 are 16.9 × 9.9 mm; the hole on the horizontal part 51 used for connection is an oblong hole.

[0030] During assembly, the beam fixing seat 7 is installed horizontally, spaced according to actual requirements and fixed to the column 100. Then, the beam insert 12 is fastened to the beam connection part 72 using bolt assemblies. Following the principle of horizontal construction, one row (height direction) of curtain wall beams 6 is first inserted into the insertion part 121 and fastened with self-tapping screws, then the other row is installed. After all curtain wall beams 6 are installed, the hanging bracket fixing seat 5 is installed. The bolts of the bolt assembly are inserted into the bolt slots 61 and moved to the set position. The holes on the horizontal part 51 of the hanging bracket fixing seat 5 are fitted onto the bolts and tightened with the nuts of the bolt assembly. Next, the terracotta panel 1 is prefabricated in the factory, in a U-shape... The nut 200 in the clip 3 is used for limiting and fixing, so that the nut 200 is aligned with the clip hole 31. Then, the terracotta plate 1 is drilled to expose the nut 200. At this time, a gasket can be placed between the nut 200 and the through groove 32 of the U-shaped clip. At the same time, a sleeve 300 is also placed in the hole on the terracotta plate 1. Then, the bolt 201 passes through the hole on the terracotta plate connecting part 43 of the hanger 3, the rubber gasket 10, the hole on the terracotta plate 1 and the clip hole 31, and is threadedly connected and tightened with the nut 200. Finally, the hangers are hung in sequence and the locking screw 8 is tightened to connect and fix the hanger 3 to the hanger fixing seat 5. The terracotta plate 1 is adjusted and positioned by adjusting the adjusting screw 9.

[0031] This invention improves the maneuverability and installation flatness of terracotta panel curtain walls by replacing the traditional T-slot with a U-shaped retaining strip installed in the original cavity of the terracotta panel and then connecting and fixing it with the hanger via bolt assembly. In addition, the U-shaped retaining strip increases the contact area between the hanger system and the terracotta panel, making the terracotta panel more evenly stressed.
