To avoid structural risks such as cracking, deformation joints are often set in building projects to avoid risks such as later cracking. However, the formation of deformation joints results in a poor facade effect on the outer wall. Summary of the Invention

[0040] Furthermore, curtain wall cover plates are fixedly provided on the sides away from each other of the two sets of stabilizing members 3; by fixedly providing multiple sets of curtain wall cover plates, these curtain wall cover plates not only play a decorative role, but also enhance the enclosure and durability of the entire curtain wall structure.

[0041] Furthermore, the positioning member 1 includes a galvanized angle steel connector 11, which is fixedly provided on both sides of the deformation joint;

[0042] A vertical galvanized square pipe 12 is fixedly provided on the top of the galvanized angle steel connector 11;

[0043] The EPDM expansion rubber strip 2 is fixedly provided between the two sets of vertical galvanized square pipes 12;

[0044] The galvanized angle steel connector 11 is provided on both sides of the deformation joint through chemical bolts, and multiple sets of galvanized angle steel connectors 11 are arranged at equal intervals along the direction of the deformation joint crack. The vertical galvanized square pipe 12 is provided on the opposite side of the two sets of galvanized angle steel connectors 11, and the vertical galvanized square pipe 12 is fixedly provided on the galvanized angle connector through stainless steel bolts. The two sets of vertical galvanized square pipes 12 are fixedly provided with the EPDM expansion rubber strip 2, and the EPDM expansion rubber strip 2 is fixed to the galvanized square pipe through self-tapping screws. The EPDM expansion rubber strip 2 has a certain deformation amount to ensure that it can cover the entire deformation joint and prevent water seepage in the later stage.

[0045] Furthermore, horizontal keels 13 are fixedly provided on the sides away from each other of the two sets of vertical galvanized square pipes 12; the horizontal keels 13 are fixedly provided on the vertical galvanized square pipes 12. Through the installation of the horizontal keels 13, the vertical square pipes can be installed more stably.

[0046] Furthermore, the curtain wall panel 5 is provided with a matching supporting keel 51, and the supporting keel 51 is fixedly provided on the stabilizing member 3;

[0047] The fixing member 3 includes a U-shaped groove plate 31 fixedly arranged at the end of the vertical galvanized square pipe 12. It is fixedly arranged at one end of the vertical galvanized square pipe 12 away from the outer wall facade through self-tapping screws. The supporting keel 51 is fixedly arranged on the U-shaped groove plate 31, and the end of the curtain wall panel 5 is fixedly arranged inside the U-shaped groove plate 31. The curtain wall panel 5 is arranged at the front end of the supporting keel 51, and the curtain wall panel 5 is stably installed through the U-shaped groove plate 31 and the supporting keel 51; the vertical galvanized square pipe 12 is fixedly connected with the adjacent curtain wall panel 5 in the vertical direction through the horizontal keel 13.

[0048] Further, the cover plate kit 4 includes a deformation joint cover plate 41 and a deformation joint cover plate lock 42 respectively arranged on two groups of fixing members 3; the ends of the deformation joint cover plate 41 and the deformation joint cover plate lock 42 are connected;

[0049] The deformation joint cover plate 41 is fixedly arranged on one group of U-shaped groove plates 31, and the deformation joint cover plate lock 42 is fixed on the other group of U-shaped groove plates 31. The opposite ends of the deformation joint cover plate 41 and the deformation joint lock can be buckled and fixed.

[0050] Further, a foam rod 43 and a silicone weatherproof sealant 44 are arranged at the connection of the deformation joint cover plate 41 and the deformation joint cover plate lock 42;

[0051] Before the deformation joint cover plate 41 and the deformation joint cover plate lock 42, the gap between the deformation joint cover plate 41 and the deformation joint cover plate lock 42 is first filled with the foam rod 43, then filled with the silicone weatherproof sealant 44, and finally the aluminum alloy buckle plate 32 is pressed into the U-shaped groove plate 31.

[0052] The external facade effect of the deformation joint concealed curtain wall closed structure is similar to a square strip, shown in coordination with the surrounding curtain walls. At the same time, the deformation joint is not visible from a distance, and its width is generally controlled between 200 and 350 mm.

[0053] A construction method applied to the above-mentioned deformation joint concealed curtain wall closed structure of the external wall facade includes the following steps:

[0054] First, chemical bolt holes are drilled on the external wall facade. The chemical bolt holes are drilled on both sides of the deformation joint and arranged along the direction of the deformation joint at a fixed spacing;

[0055] The chemical bolts are connected to the drilled chemical bolt holes, and through the connection of the chemical bolts with the external wall facade, the positioning member 1 is fixed on both sides of the deformation joint of the external wall facade;

[0056] An ethylene propylene diene monomer (EPDM) expansion rubber strip 2 is fixed between two groups of positioning members 1 located on both sides of the deformation joint, so that the EPDM expansion rubber strip 2 covers the deformation joint.

[0057] Before operation, first install the operation platform, i.e., the hanging basket. Workers carry out on-site operations on the hanging basket. First, fix the galvanized angle steel connector 11 on the outer wall facade through chemical bolts, connect the vertical galvanized square pipe 12 with the galvanized angle steel connector 11 through stainless steel bolts, and then install the horizontal keel 13 to stabilize the vertical galvanized square pipe 12. Then, fix the EPDM expansion rubber strip 2 on the vertical galvanized square pipe 12 to cover the entire deformation joint to avoid water seepage in the later stage. Then, fix the U-shaped groove plate 31 on the vertical galvanized square pipe 12 through self-tapping screws, and then fix the deformation joint cover plate 41 and the deformation joint cover plate lock 42. Note that the gap between the deformation joint cover plate 41 and the deformation joint cover plate lock 42 is first filled with a foam rod 43 and then filled with silicone weatherproof sealant 44. Finally, press the aluminum alloy buckle plate 32 into the U-shaped groove plate 31 to complete all construction contents.

[0058] The present invention uses the EPDM expansion rubber strip 2, chemical bolts, keels and aluminum plates to be fixed at the deformation joint. By setting the deformation joint cover plate 41 and the deformation joint cover plate lock 42, the deformation joint is hidden therein, so as to achieve the appearance effect. At the same time, it also avoids problems such as cracks and damages in the later stage of the building, extends the service life of the building, reduces water seepage, increases aesthetics, and saves the later maintenance cost to a certain extent.

[0059] Finally, it should be pointed out that the methods and devices described in detail above are only examples, and those skilled in the art can modify these examples in different ways as long as they do not depart from the scope of the present invention.
