Description

Technical Field

[0001] The utility model relates to the technical field of curtain wall construction, and particularly relates to a dry-hanging ceramic panel installation and fixing structure. Background Art

[0002] In the decoration of building facades, ceramic panels are widely used in the external wall dry-hanging system due to their excellent weather resistance, aesthetics and plasticity. In the traditional vertical dry-hanging construction of external wall ceramic panels, a common technical solution is to insert fixed hanging parts into the reserved holes of the ceramic panels, and then fix the ceramic panels by adjusting screws. Since the adjustable range of the traditional hanging parts relative to the ceramic panels is limited, usually only one-way adjustment can be achieved along the depth direction, which makes the drilling of the horizontal keel very precise and requires zero error during installation. If the size of the ceramic panel is not standard, or there is a deviation between the hole position and the position of the hanging part and it is difficult to align, due to the limited adjustment space, great difficulties will be faced during the installation process, which is likely to cause rework of the horizontal keel, resulting in an extended construction period and increased costs.

Please note that, in order to clearly show the structure of the components of the embodiments of this utility model, the drawings are not drawn to the same scale. The same reference numerals are used to indicate the same parts.

[0023] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model. The following is combined with Figure 1-2 to further elaborate on the preferred embodiments of the present utility model:

[0024] As Figure 1-2 shown, a preferred installation and fixing structure for dry-hung ceramic panels of the present utility model includes a curtain wall keel 3, an attachment component 2, a curtain wall hanging piece 5, and a ceramic panel 9. The curtain wall keel 3 includes a vertically arranged keel 301 and a horizontally arranged keel 302 that are fixedly connected. The vertically arranged keel 301 is fixed to the main structure 1 through the attachment component 2. The main body of the curtain wall hanging piece 5 is a horizontally placed cross-shaped structure. The horizontal plate at its inner end overlaps and is fixedly connected to the horizontally arranged keel 302. The horizontal plate at its outer end and the vertical plate form a slot for accommodating the ceramic panel 9. The outer end of the curtain wall hanging piece 5 extends to the horizontal joint of the ceramic panel 9. The bottom edge of the ceramic panel 9 above the joint and the top edge of the ceramic panel 9 below the joint are correspondingly inserted into the slot formed by the horizontal plate and the vertical plate at the outer end of the curtain wall hanging piece 5;

[0025] Among them, the attachment component 2 can be pre-buried by synchronous setting out during the casting construction stage of the main structure 1, or can be set on the completed surface of the main structure 1 by post-anchoring after the construction of the main structure 1 is completed. As Figure 1-2 shown, in some preferred embodiments, the attachment component 2 includes an attachment plate 201, anchor bolts 202, and attachment arms 203. The attachment plate 201 is attached to the outer surface of the main structure 1 and is anchored to the main structure 1 through a plurality of anchor bolts 202. The attachment arms 203 are arranged in pairs. The two attachment arms 203 arranged in pairs are correspondingly arranged on both sides of the vertically arranged keel 301. Their inner ends abut against the attachment plate 201 and are welded and fixed to the attachment plate 201. Their outer ends extend away from the main structure 1 to form a cantilever end. A long circular hole extending in the depth direction is correspondingly formed in the cantilever end of the attachment arm 203, and a tooth groove is formed in the attachment arm 203 on the periphery of the long circular hole. A connecting bolt 6 is inserted into the long circular hole, and the connecting bolt 6 cooperates with a toothed gasket 7 that matches the tooth groove to connect and fix the vertically arranged keel 301 and the attachment arm 203;

[0026] During construction, construction errors are inevitably introduced in each construction process. In order to improve the tolerance of the entire fixed installation structure and reduce the construction difficulty on site, in some preferred embodiments, the curtain wall keel 3 also includes a connecting bracket 303. The connecting bracket 303 is set on the vertical keel 301 at the end of the horizontal keel 302 as a support for the horizontal keel 302. The connecting bracket 303 is provided with an elongated hole extending in the vertical direction, and the connecting bracket 303 on the periphery of the elongated hole is provided with a toothed groove. A connecting bolt 6 passes through the elongated hole, and the connecting bolt 6 cooperates with a toothed washer 7 that matches the toothed groove to connect and fix the connecting bracket 303 to the vertical keel 301.

[0027] Furthermore, an elongated hole extending along the depth direction is correspondingly opened on the horizontal plate at the inner end of the curtain wall hanger 5, and a toothed groove is opened on the curtain wall hanger 5 around the elongated hole. A connecting bolt 6 is inserted into the elongated hole, and the connecting bolt 6, together with a toothed washer 7 matching the toothed groove, connects and fixes the curtain wall hanger 5 to the horizontal keel 302. Furthermore, in order to avoid structural noise and to avoid damage to the corners of the terracotta panel 9 caused by rigid components, flexible washer 8 is provided between the curtain wall hanger 5 and the horizontal keel 302 and between the curtain wall hanger 5 and the terracotta panel 9.

[0028] By opening the elongated hole, the positions of each set of connecting bolts 6 used for fixing the components can be adjusted along the elongated hole to absorb the installation errors of the corresponding components in each installation stage. At the same time, the cooperation of the toothed grooves and toothed washers 7 on the periphery of the elongated hole further avoids the problem of misalignment of the connecting bolts 6 after positioning, effectively ensuring the completion accuracy and stability of the installation and fixing structure.

[0029] To reduce construction difficulty, workload, and improve the aesthetics and waterproofing of the curtain wall facade, the terracotta panel 9 has tongue-and-groove joints along its edges. The upper edge of the terracotta panel 9 has an L-shaped tongue-and-groove joint, with the inner end of the joint higher than its outer end. The lower edge of the terracotta panel 9 has an inverted U-shaped tongue-and-groove joint, with the outer end higher than its inner end. The vertical joints of the terracotta panels 9 are sealed with caulking material, while the horizontal joints are not sealed with caulking material. The material also serves as a drainage channel. Due to the obstruction of the bottom edge tongue and groove of the terracotta panel 9 and the characteristic of the top edge tongue and groove of the terracotta panel 9 being higher inside and lower outside, it is difficult for a large amount of rainwater to enter the horizontal joint. Even if a small amount of water penetrates into the horizontal joint, the tongue and groove of the top edge of the terracotta panel 9 will act as a water-blocking protrusion to prevent rainwater from seeping into the space behind the terracotta panel 9. Moreover, the top edge tongue and groove, which is higher inside and lower outside and has rounded corners, will fully utilize the characteristics of the water-guiding slope to quickly drain the rainwater that seeps into the gap to the outside of the gap, preventing rainwater from accumulating.

[0030] The specific construction process of this utility model is as follows:

[0031] Step 1: Based on the structural characteristics of the attachment component 2, pre-embedded parts are reserved during concrete pouring or the layout construction is carried out in a rearward manner after the main structure 1 is poured. When installing the curtain wall keel 3, select the vertical keel 301 and attachment arm 203 according to the number on the keel layout drawing. Connect the vertical keel 301 and attachment arm 203 with 2 sets of M12 stainless steel bolts. According to the position line and elevation line of the vertical keel 301 on the wall, temporarily fix the vertical keel 301 accurately. The channel steel attachment arm 203 is connected to the attachment plate 201 on the structure by fillet welding. After the vertical keel 301 is constructed, install the connecting bracket 303 on it according to the layout position, and further install the horizontal keel 302. After the horizontal keel 302 is accurately adjusted, weld it to the vertical keel 301. Then, fill the curtain wall keel 3 on the outside of the main structure 1 with thermal insulation rock wool 4 to form an insulation layer.

[0032] Step 2: Install fireproof isolation strips at the beams between layers. The isolation strips are made of 1.5mm thick galvanized steel plates. One side of the steel plate is fixed to the main structure 1 with M8×40 expansion bolts and welded to the vertical keel 301. The gap where the other side meets the terracotta panel 9 is sealed with fireproof sealant.

[0033] Step 3: Based on the three-dimensional control lines of the wall terracotta panel 9, select the accessories according to the accessory numbers shown on the construction detail drawing, inspect the quality of the accessories before installing them, and install the terracotta panels 9 one by one according to the wall terracotta panel 9 numbers.

[0034] Step 4: For the vertical 8mm wide seams of the terracotta panel 9 on the wall, use 10mm polystyrene foam strips as the caulking base material. Then, use special silicone weather-resistant sealant for terracotta panels to further seal the gaps on the surface of the caulking base material. Before caulking the terracotta panel 9, stick 50mm wide masking tape on both sides of the seam of the terracotta panel 9. Insert polystyrene foam strips into the seam and inject special silicone weather-resistant sealant for terracotta panel 9 seams using a caulking machine. The horizontal seams serve as drainage channels and are not treated with sealant.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
