[0002] A curtain wall is an exterior wall enclosure of a building, which is not load-bearing and is hung like a curtain, so it is also called a "curtain wall". It is a lightweight wall with decorative effects commonly used in modern large-scale and high-rise buildings. It is composed of a panel and a support structure system, and can have a certain displacement ability relative to the main structure or have a certain deformation ability itself, and does not bear the action of the main structure. It is an exterior enclosure structure or decorative structure of a building.

[0003] In buildings with curtain walls, most curtain walls have cavity structures that run through vertically and horizontally. During a fire, a chimney effect will occur. If no separation measures are taken, it will intensify the rapid spread of the fire horizontally and vertically, leading to the entire building catching fire and making it difficult to carry out fire fighting. Therefore, a fireproof structure and construction method for the wall gaps along the curtain wall are needed to provide fire separation between the curtain wall and the wall gaps along the wall and slow down the spread of the fire.

Then, by screwing the screws on the threaded hole plates, the screws are made to abut against the embedded steel plate, and the fixation of the galvanized steel plate can be achieved. The operation is simple and fast. Compared with welding, if the position deviates, the overall operation is more troublesome.

[0011] Preferably, four through holes are provided on the corner code, and reinforcing ribs are welded at both ends inside the corner code.

[0018] A construction method for the fireproof structure of the gap along the wall of a curtain wall, the steps of the construction method are as follows:

[0019] Step 1: The anti-slip chute on the galvanized steel plate is sleeved on the anti-slip rail, and the galvanized steel plate is translated so that the anti-slip chute slides on the surface of the anti-slip rail to prevent the galvanized steel plate from falling off. After the galvanized steel plate is aligned with the support connecting plate, the screw is screwed so that one end of the screw abuts against the embedded steel plate to fix the galvanized steel plate. Pick up the wrench and put it on the hexagonal rotating block to drive the threaded sleeve to rotate, so that the threaded rod moves to the left. The threaded rod then drives the angle code to move to the left. After the through hole on the angle code is aligned with the long hole, put on the fastening bolt and tighten it, so that the angle code and the support connecting plate are fixed.

Then, lay fireproof rock wool with a thickness greater than mm on the inner side of the plugging galvanized channel plate. Then the user picks up the galvanized L-shaped plate and covers it on the top of the plugging galvanized channel plate, so that the fireproof rock wool is located between the plugging galvanized channel plate and the galvanized L-shaped plate. The holes on the plugging galvanized channel plate will also be sleeved on the surface of the expansion bolts. Then put on the nut and tighten it;

[0021] Step 3: Then, lay the ground layer on the galvanized L-shaped plate and the floor slab according to the ground construction. Then fill silicone rubber at the joint between the ground layer and the curtain wall skeleton.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

Then, a fireproof isolation belt is laid between the two support connecting plates, and the sealing galvanized channel plate is placed on the top of multiple galvanized steel plates. Then, fireproof rock wool is laid in the inner cavity of the sealing galvanized channel plate, and the galvanized L-shaped plate is fixed to the sealing galvanized channel plate by expansion bolts, so as to achieve fireproof sealing at the position of the floor slab and the curtain wall, and the purpose of making fireproof isolation between the curtain wall and the gap along the wall and slowing down the spread of fire can be achieved. This solves the problem that in buildings with curtain walls, mainly due to the cavity structure existing in most curtain walls, these cavities are vertically and horizontally connected, and chimney effect will occur in case of fire. Without taking certain separation measures, it will exacerbate the rapid spread of fire horizontally and vertically, resulting in the whole building catching fire and being difficult to extinguish.

[0024] 2. Through the combined use of anti-derailment, anti-derailment chute, threaded hole plate and screws, the anti-derailment chute on the galvanized steel plate can slide on the anti-derailment on the embedded steel plate, and the position of the galvanized steel plate can be adjusted back and forth. Then, by turning the screws on the threaded hole plate, the screws can be made to abut against the embedded steel plate to fix the galvanized steel plate. The operation is simple and fast. Compared with welding, if there is a deviation in position, the overall operation is more troublesome.

[0025] 3. Through the setting of the long hole, after the perforation on the corner code is aligned with the long hole, the fastening bolt can be installed, which is simpler and faster than the alignment of two round holes.

[0026] 4. Through the setting of the reinforcing rib, the strength of the overall structure of the corner code can be increased, the possibility of deformation of the corner code can be reduced, and the tolerance of the corner code can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

The spacing between the holes on the blocking galvanized trough plate (9) and the galvanized L-shaped plate (11) is the same. When the blocking galvanized trough plate (9) is picked up and laid on the top of the plurality of galvanized steel plates (7), the left side of the blocking galvanized trough plate (9) is attached to the curtain wall frame (2), and the right side of the blocking galvanized trough plate (9) is attached to the floor plate. The blocking galvanized trough plate (9) is attached to the supporting plate (5), the curtain wall frame ( 2) The contact position with the floor deck is coated with glue. At this time, the hole on the blocking galvanized trough plate (9) is covered on the expansion bolt (12) embedded in the floor plate. Then, a fireproof rock wool (10) with a thickness greater than 100 mm is laid on the inner side of the blocking galvanized trough plate (9). Then, the user picks up the galvanized L-shaped plate (11) and covers it on the top of the blocking galvanized trough plate (9) so that the fireproof rock wool (10) is located between the blocking galvanized trough plate (9) and the galvanized L-shaped plate (11). The hole on the blocking galvanized trough plate (9) is also covered on the surface of the expansion bolt (12). Then, the nut is put on and tightened. Step 3: Then, the ground layer (13) is laid on the galvanized L-shaped plate (11) and the floor plate according to the ground construction, and then the silicone glue (14) is filled between the ground layer (13) and the curtain wall frame (2).
