DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0037] The present application provides an indoor expansion joint cover plate structure, which can connect two independent spaces and ensure that the expansion joint cover plate structure can be buffered when the settlement and shrinkage are inconsistent. The expansion joint cover plate structure comprises a ground, a wall surface and a top plate. The ground, the wall surface and the top plate are separated and overlapped to form a smooth finished surface, and the overall appearance of the indoor room can be enhanced by combining with a decorative surface.

[0038] Mainly, the present application provides the following technical solutions:

[0039] An expansion joint cover plate structure comprises a ground support module unit, a wall surface module unit and a top plate expansion joint structure.

[0040] The ground support module unit is provided with a certain number of corbel supports on the wall between two independent structures, a steel plate is laid on the supports to form a smooth ground, and the internal support members are covered by a decorative method of laying tiles on the ground.

[0041] The wall surface module unit is fixed with main and auxiliary sections on the wall above the ground of two buildings, and gypsum boards are used to close the wall surface to form a smooth wall surface between the two walls.

[0042] The top plate expansion joint structure is formed by using gypsum boards to separate and overlap when the indoor ceiling is suspended, and the structure can freely expand and contract.

[0043] The indoor expansion joint cover plate structure of the embodiment of the present application will be described in detail below with reference to the drawings.

[0044] 1) After the construction of the structural wall 1 is completed, a width of 800mm expansion joint is left between the two walls 1, and a triangular support frame 2 is arranged in the expansion joint. The support steel plate 21 is fixed on the structural wall 1 on one side by expansion bolts 22, and the size of the steel plate 21 is 100mm x 100mm. The triangular support frame 2 is welded by 8# channel steel, and is welded on the fixed steel plate 21. The horizontal length of the triangular support frame 2 is 750mm, and a gap of 50mm width (i.e. the first gap) is reserved. The vertical length is 500mm. As shown in Figure 1 and Figure 2 .

[0045] 2) After the triangular support frame 2 in the expansion joint is installed, a layer of steel plate is laid above the support frame 2 as the first cover plate 3. The thickness of the steel plate is 8mm, the width is 790mm, and a gap of 10mm (i.e. the second gap) is reserved. The steel plate is laid on the triangular support frame 2 and inlaid at the expansion joint, covering the expansion joint to make the structural ground flat, i.e. the top finished surface of the steel plate is at the same height as the ground, which is convenient for the later ground decoration construction. As shown in Figure 3 .

[0046] 3) After the first cover plate 3 at the bottom is laid, a finished surface at the same height as the bottom plate is formed at the expansion joint position between the two buildings. When the ground decoration construction is carried out at this position, the mortar 4 and the floor tile 5 can be directly laid. When the floor tile 5 at this position is laid, a separation joint of 10mm width (i.e. the third gap) is arranged, and the separation joint gap is sealed by a "T-shaped" stainless steel joint strip 6. As shown in Figures 4-6 . The T-shaped stainless steel joint strip includes a top plate 61 and two side plates 62 arranged on the lower surface of the top plate 61, and the distance between the two side plates 62 is suitable for the width of the third gap (i.e. 10mm).

[0047] 4) The wall module unit is a structural unit composed of customized special-shaped light steel studs 7 and gypsum boards 10 between the two walls 1 at the expansion joint position in the room above. After the wall 1 in the room is built, the customized special-shaped light steel studs 7 are fixed on the two walls 1 by T50 drywall steel nails 8. As shown in Figure 7 .

[0048] 5) The lower part of the special-shaped light steel stud 7 is provided with a movable area (i.e. the movable groove 9), and a gypsum board 10 is placed at this position. The gypsum board 10 has a certain movable space at both ends, which can be freely moved up and down and left and right. As shown in Figure 8 and Figure 9 .

[0049] 6) After the inner movable gypsum board 10 is installed, fill the space in the upper part of the special-shaped light steel keel 7 with thermal insulation rock wool 10 to prevent cold and heat bridge phenomenon and play the role of filling and thermal insulation; at the same time, set a C75 light steel keel as a reinforcing keel 12 at the middle part to fix the outer gypsum board (i.e. the second cover plate 13), as shown in Figure 10

[0050] 7) After the previous step is completed, use double 12mm thick gypsum board as the third cover plate 13 to overlap and fix, and opposite splicing, leaving a 30mm wide first deformation buffer joint 14 in the middle to ensure that the gypsum board can freely stretch and contract, as shown in Figure 11

[0051] 8) When the gypsum board (i.e. the third cover plate 17) is used to overlap and fix and opposite splicing when the gypsum board is used to decorate the ceiling in the room, leaving a 30mm wide second deformation buffer joint 18 at the joint, as shown in Figure 12 The gypsum board also uses double 12mm thick gypsum board, and the overlapping part in the middle is stepped, and after overlapping, the double gypsum board has a 30mm wide second deformation buffer joint 18 in the middle. The gypsum board is fixed on the suspended ceiling keel 16 through fixing accessories (such as hoops, buckles, etc.), and the suspended ceiling keel 16 is hung on the ceiling elevation position through the hanger 15.
