[0027] Some of the specific implementation manners described below are intended to facilitate those skilled in the art to understand this embodiment, and this embodiment is not limited to some of the specific implementation manners described below.

[0028] Reference Figure 1 , a floor slab drop building deformation joint device provided by an exemplary embodiment of the present disclosure, the floor slab drop building deformation joint device includes:

[0029] A cover plate 1, spanning over the deformation joint 7 and used to vertically cover the deformation joint 7, one end of the cover plate 1 is bent and extends downward, and the top surface of the cover plate 1 is in a horizontal posture;

[0030] A support body 2, fixed between the cover plate 1 and the building body 4 and used to support the cover plate 1, the bent end of the cover plate 1 and the support body 2 are distributed at intervals;

[0031] A water stop belt 3, fixed inside the deformation joint 7 and vertically covering the deformation joint 7, the water stop belt 3 is located below the cover plate 1;

[0032] A fire stop belt 5, fixed inside the deformation joint 7 and vertically covering the deformation joint 7, the fire stop belt 5 is located below the water stop belt 3.

[0033] Exemplarily, referring to Figure 1 , the deformation joint 7 is formed between two parts of the building body 4, and is in a groove-like structure with an opening vertically upward, and there is a height difference between the top surfaces of the two parts of the building body 4 forming the deformation joint 7. Both ends of the cover plate 1 are respectively placed on the top surfaces of the two parts of the building body 4, and the end of the cover plate 1 placed on the building body 4 with a lower horizontal position is bent downward and supported on the top surface of this part of the building body 4, so that the top surface of the cover plate 1 is in a horizontal posture.

[0034] The support body 2 is fixedly connected to the top surface of the building body 4 with a lower horizontal position, the bottom end of the support body 2 is fixedly connected to the building body 4, the top end of the support body 2 abuts against the bottom surface of the cover plate 1, the end of the cover plate 1 bent downward is located on the side of the support body 2 away from the building body 4 with a higher horizontal position, and a gap is formed between the end of the cover plate 1 bent downward and the support body 2.

[0035] The water stop belt 3 is fixed between the two parts of the building body 4, both ends of the water stop belt 3 are respectively fixed on the opposite side walls of the two parts of the building body 4, and the water stop belt 3 is in an arc posture protruding vertically downward. For example: the water stop belt 3 is an ethylene propylene diene monomer rubber coil and is fixed on the opposite side walls of the two parts of the building body 4 inside the deformation joint 7 through epoxy resin, and both ends of the water stop belt 3 are flush with the top surface edge of the building body 4 with a lower horizontal position.

[0036] The fire stop belt 5 is fixed between the two parts of the building body 4, both ends of the fire stop belt 5 are respectively fixed on the opposite side walls of the two parts of the building body 4, and the fire stop belt 5 is in an arc posture protruding vertically downward, and the end of the fire stop belt 5 is flush with the bottom end of the water stop belt 3 in the natural state.

[0037] In this embodiment, the cover plate 1 is supported by the support body 2, so that both ends of the cover plate 1 are at the same height, increasing the contact area between the cover plate 1 and the building body 4 and reducing the possibility of a gap being generated between the cover plate 1 and the building body 4; the support body 2 cooperating with the downwardly bent end of the cover plate 1 can also shield the top edge of the building body 4 with a lower horizontal position, reducing the possibility of foreign objects on the building body 4 with a lower horizontal position entering the inside of the separation joint; the water stop belt 3 can reduce the possibility of liquid on the upper floor building falling into the lower floor building body 4 through the separation joint, and the fire stop belt 5 can prevent the ignition source on the upper floor building body 4 from entering the lower floor building body 4 through the separation joint, reducing potential safety hazards.

[0038] In an exemplary embodiment of the present disclosure, referring to Figure 1 , the fire stop belt 5 includes a first metal fire-resistant layer 53, a fiber felt fire-resistant layer 52, and a second metal fire-resistant layer 51 stacked in sequence.

[0039] Exemplarily, referring to Figure 1 , the top surface of the first metal fire-resistant layer 53 faces the water stop belt 3, the bottom surface of the first metal fire-resistant layer 53 is attached to the fiber felt fire-resistant layer 52, the bottom surface of the fiber felt fire-resistant layer 52 is attached to the top surface of the second metal fire-resistant layer 51, the bottom surface of the second metal fire-resistant layer 51 is arranged away from the water stop belt 3, and the ends of the first metal fire-resistant layer 53, the fiber felt fire-resistant layer 52, and the second metal fire-resistant layer 51 are flush and riveted to form an integral structure.

[0040] In this embodiment, the first metal fire-resistant layer 53 and the second metal fire-resistant layer 51 can be stainless steel plates bent into an arc shape, and the fiber felt fire-resistant layer 52 can be a refractory fiber felt made of aluminum silicate. There is a fireproof caulking agent between the fire stop belt 5 and the deformation joint 7. The fireproof caulking agent covers the bottom edge of the second metal fire-resistant layer 51 and covers the side walls of the two opposite parts of the building body 4 located in the deformation joint 7. The fireproof caulking agent is filled between the bent fire stop belt 5 and the side wall of the building body 4 to form a fireproof fixing part 22.

[0041] In an exemplary embodiment of the present disclosure, referring to Figure 1 and Figure 2 , the cover plate 1 includes a covering section 11 for straddling the deformation joint 7, and a supporting section 12 located at the end of the covering section 11 and used for supporting the covering section 11.

[0042] Exemplarily, referring to Figure 1 and Figure 2 , the covering section 11 is in a horizontal posture and straddles the deformation joint 7. One end of the covering section 11 abuts against the top surface of the building body 4 with a higher horizontal position, the other end is integrally formed with the supporting section 12, the supporting section 12 is in a vertical posture and the bottom end abuts against the top surface of the building body 4 with a lower horizontal position, and the cover plate 1 is in a horizontally placed L shape.

[0043] In this embodiment, the support body 2 includes at least an upwardly extending support portion 21 and a fixing portion 22 for contacting the building 4. The fixing portion 22 is horizontal and contacts the lower horizontal top surface of the building 4. The support portion 21 is vertical and integrally formed at the end of the fixing portion 22 facing the expansion joint 7. The top end of the support portion 21 abuts the cover plate 1, and a gap is formed between the end of the fixing portion 22 facing away from the expansion joint 7 and the support segment 12.

[0044] In other embodiments, the fixing portion 22 has a guide slope 221 for allowing the supporting segment 12 to pass through and slide onto the fixing portion 22 , and the supporting segment 12 has a transition slope 121 adapted to the guide slope 221 .

[0045] For example, refer to Figure 1 and Figure 2 The guiding bevel 221 and the transition bevel 121 extend in the same direction and have the same slope, and are arranged opposite to each other. When the two parts of the building 4 undergo relative displacement, the width of the deformation joint 7 increases or decreases. When the width of the deformation joint 7 increases, the distance between the support section 12 and the fixing portion 22 decreases, and the support section 12 may even abut against the fixing portion 22. When the width of the deformation joint 7 continues to increase, the transition bevel 121 can abut against the guiding bevel 221 and continue to move diagonally upward under the action of the guiding bevel 221. At this time, the bottom end of the support section 12 is gradually lifted by the fixing portion 22, thereby causing the lower end of the cover plate 1 to tilt up, which is used to remind the user that the width of the deformation joint 7 is too large. This can not only achieve the purpose of warning, but also reduce the possibility of excessive mutual abutment between the supporting section 12 and the fixing portion 22 during the process of increasing the width of the deformation joint 7, which may cause damage to the cover plate 1 and create safety hazards.

[0046] In an exemplary embodiment of the present disclosure, referring to Figure 1 and Figure 3 The cover plate 1 is fixed to the building 4 by screws 6. The cover plate 1 has a through groove 13 for accommodating the screws 6 and providing the screws 6 with a sliding groove 13 along the expansion and contraction direction of the deformation joint 7.

[0047] For example, refer to Figure 1 and Figure 3, the cover plate 1 is attached to the end of the building 4 with a relatively high horizontal position and fixed by screws 6. The through groove 13 has a counterbore structure in the shape of a waist-shaped hole and is arranged along the opening and closing direction of the deformation joint 7. A through hole 14 penetrating the cover plate 1 in the vertical direction is provided inside the waist-shaped hole. The through hole 14 is also in the shape of a waist-shaped hole, but the size of the through hole 14 is smaller than that of the through groove 13. The bottom surface of a part of the through groove 13 is arranged around the top edge of the through hole 14. The screw 6 extends into the building 4 after passing through the through hole 14, and the end of the screw 6 is located inside the through groove 13 of the counterbore structure. Multiple screws 6 can be connected to the same cover plate 1 according to actual working conditions. When the width of the deformation joint 7 increases to the support section 12 abuts against the support part 21, as the width of the deformation joint 7 continues to increase, the end of the screw 6 will slide along the length direction of the through groove 13 inside the through groove 13 relative to the cover plate 1 to meet the continuously increasing width of the deformation joint 7, slow down the increasing speed of the abutting force between the support section 12 and the support part 21, slow down the failure time of the cover plate 1 due to breakage, and reduce potential safety hazards.

[0048] In this embodiment, the support body 2 is also fixedly connected to the building 4 by screws 6 penetrating the fixing part 22 in the vertical direction, and the fire stop belt 5 is also fixed to the side wall of the building 4 by screws 6 sequentially penetrating the first metal refractory layer 53, the fiber felt refractory layer 52, and the second metal refractory layer 51.

[0049] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
