Description
Technical Field
[0001] The present invention relates to the technical field of building deformation joint structures, and in particular to a deformation joint structure and a construction method thereof. Background Art
[0002] At present, various large-scale buildings, high-low staggered buildings, and special-shaped buildings are being built in large quantities. During the construction process, more and more deformation joints such as settlement joints, expansion joints, and seismic joints have appeared. The purpose of setting building deformation joints is to solve the problem of excessive longitudinal length of buildings, complex floor plans, or large differences in height and load in different parts of the same building. Taking into account factors such as earthquake resistance and temperature changes, deformation joints are set vertically along the building in easily deformed parts to prevent additional pressure generated by longitudinal expansion and contraction changes of building components or uneven settlement of the foundation, which may cause deformation and damage to the building. However, at present, deformation joints are mostly customized products made by manufacturers, with high costs, requiring a certain processing cycle, and are not hidden after construction is completed. The appearance is unsightly, affecting the overall beauty of the building. In terms of the deformation direction, most existing deformation joints only guarantee deformation in one direction, and do not have the ability to adapt to deformation in multiple directions. Summary of the Invention

[0012] Preferably, the slope layer is made of fine stone concrete, the leveling layer is made of cement mortar, and the insulation layer is a 60 mm insulation board made of polystyrene resin material.
[0013] A construction method for a deformation joint structure comprises the following steps:
[0014] Step 1: Install the first mounting plate. Install the first mounting plate in the building deformation joint, with surface b affixed to the bottom of the groove of the building deformation joint, surface a being parallel to but not affixed to the side of the structural beam, and surfaces c, d, and e affixed to and fixed on the surface of the base column.

This construction method is simple and convenient to operate, with a short construction period. The overall structure of the deformation joint is hidden inside the finishing layer, and the appearance is simple and neat with good aesthetics. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be further described below with reference to the accompanying drawings:
[0024] like Figure 1 and Figure 2 The deformation joint structure shown includes a groove-shaped connector 2 installed on a building deformation joint 1. The building deformation joint 1 is formed by the gap between the base columns 10 and the structural beams 11 arranged at intervals. The base column 10 is set on the concrete slab 30, and a gap is left between the edges of the corresponding side of the concrete slab 30; the groove-type connector 2 includes a first mounting plate 21 and a second mounting plate 22 sealed by a seal 20, the first mounting plate 21 is set in the building deformation joint 1, close to the side of the base column 10, and the first mounting plate 21 is located above the concrete slab 30; the first mounting plate 21 includes an a-surface 210, a b-surface 211, a c-surface 212, a d-surface 213 and an e-surface 214 that are connected to each other vertically in sequence, the a-surface 210 is parallel and spaced apart from the side wall of the structural beam 11, and the c-surface 212, the d-surface 213 and the e-surface 214 are fixedly mounted on the surface of the base column 10. In one embodiment, the seal 20 is made of a modified waterproof sealant, and the first mounting plate 21 is made of an integrated bent steel plate. The distance between the a-surface 210 and the side wall of the structural beam 11 is not less than 50 mm, preferably 50 mm.
[0025] The second mounting plate 22 includes an inverted L-shaped A surface 220 and a B surface 221. The B surface 221 is fixedly mounted on the top of the structural beam 11. The A surface 220 is located between the a surface 210 and the c surface 212 and is sealed to the a surface 210 through the seal 20. In one embodiment, the second mounting plate 22 is also made of an integrally bent steel plate. The area of the sealing connection of the seal 20 between the A surface 220 and the a surface 210 accounts for approximately half of the surface area of the A surface 220 or the a surface 210.
[0026] The gap between surface a 210 and the sidewall of structural beam 11 forms a lateral deformation space, while the gap between the top of surface a 210 and surface B 221 and the gap between the bottom of surface A 220 and surface b 211 form a vertical deformation space. Together, these lateral and vertical deformation spaces form the deformation space of the building deformation joint. In one embodiment, the distance between the top of surface a 210 and surface B 221 is the same as the distance between the bottom of surface A 220 and surface b 211. Specifically, this distance is no less than 50 mm, and preferably 50 mm.
[0027] A slope layer 3, an insulation layer 4, a leveling layer 5, a waterproof membrane 6, an adhesive layer 7 and a finishing layer 8 are sequentially arranged on the top of the first mounting plate 1 and the second mounting plate 2. In one embodiment, the slope layer 7 is made of fine stone concrete laid on the first mounting plate 1 and / or the second mounting plate 2, the leveling layer 5 is made of cement mortar laid on the insulation layer 4, and the insulation layer 4 is a 60mm insulation board made of polystyrene resin material. One end of the waterproof membrane 6 on both sides of the building deformation joint 1 is folded down to the c-surface 212 and the A-surface 220, respectively, and is fixedly connected to the c-surface 212 and the A-surface 220, respectively.
[0028] The finishing layer 8 located at the upper end opening of the building deformation joint 1 is connected to the finishing layer 8 around it by sealant. In one embodiment, the finishing layer 8 at the upper end opening of the building deformation joint 1 and the finishing layer 8 connected thereto are fixedly installed at the bottom of the connection, and the left-right symmetric center of the third mounting plate 9 coincides with the center of the connection.

Install the first mounting plate 21 within the building expansion joint 1, with surface b 211 aligned with the bottom of the groove in the building expansion joint 1, surface a 210 parallel to but not aligned with the side of the structural beam 11, and surfaces c 212, d 213, and e 214 aligned and fixed to the surface of the base column 11. Surfaces d 213 and e 214 are bolted to the base column 11. Surfaces c 212, d 213, and e 214 wrap around the top, left, and right walls of the base column 11.
[0031] Step 2: Install the second mounting plate 22, sealingly connecting surface A 220 to the inner side of surface A 210 via seal 20. The area of this sealed connection accounts for half the surface area of surface A 210 or surface A 220. After the sealant is formed, surface B 221 is fixed to the top of the structural beam 11 with bolts.
[0032] Step 3: Top layer construction: Slope layer 3, insulation layer 4, leveling layer 5, and waterproof membrane 6 are sequentially constructed on top of first mounting plate 21 and second mounting plate 22. A layer of fine stone waterproof concrete is laid on top of waterproof membrane 6. One end of waterproof membrane 6 is folded down to surface C 212 and surface A 220, respectively, and fixedly connected to these surfaces.
[0033] Step 4: Install the third mounting plate 9. Fix the third mounting plate 9 above the structural beam 11 and near the top opening of the building deformation joint 1 with fasteners. The left and right symmetrical center of the third mounting plate 9 coincides with the connection seam of the two connected finishing layers 8.
[0034] Step 5: Apply the finishing layer 8. A bonding layer is applied to the fine stone waterproof concrete layer, followed by the decorative finishing layer 8. The finishing layer 8 at the building expansion joint is separated from the finishing layers 8 on its left and right sides and connected with sealant. Specifically, the finishing layer is made of 40-grade granite slabs.
