[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0015] like Figure 1-4 As shown, an integrated expansion joint device for the floor of an industrial building of the present invention comprises a pair of steel formworks arranged at intervals with adjustable heights and a pair of aluminum alloy frames 4 arranged at intervals corresponding to the steel formworks, a cover plate 6 arranged above the aluminum alloy frame; the bottom of the cover plate is connected to a slide rod 5 that can slide relative to the aluminum alloy frame 4 through a vertically arranged screw 14; a waterproof belt 3 is provided between the aluminum alloy frame and the steel formwork, the aluminum alloy frame is connected and fixed to the steel formwork by screws 12 passing through the waterproof belt, and elastic rubber strips 7 are provided between the two sides of the cover plate and the upper vertical portion of the steel formwork for caulking and sealing.

[0016] It should be noted that, in the present invention, a threaded connection sleeve 15 is provided in the middle of the slide rod 5, and the middle of the slide rod 5 is connected to the cover plate 6 through the threaded connection sleeve 15 and the screw 14, and the middle of the cover plate 6 has a hole for the screw 14 to pass through for installation.

[0017] The steel template includes a first template 9 located at the bottom and a second template 13 located at the top, and the first template and the second template are connected by bolts 8 through long bolt holes to form a height-adjustable connection. This makes it convenient to adjust the height of the steel template to meet the needs of different situations.

[0018] The first template and the second template are connected by an adjustable support rod formed by a threaded sleeve 1 and two threaded rods 2. This makes it easy to adjust the height of the steel template to meet the needs of adjusting support in different situations. While achieving support, it can also achieve height adjustment, which is convenient to use.

[0019] Wherein, the aluminum alloy frame can be an F-shaped structure, such as Figure 3 As shown, it can also be other shapes, which can be selected according to different working conditions, and are not limited to the specific ones; the cover plate is an aluminum alloy cover plate, which is the prior art and will not be described in detail, such as Figure 2 shown.

[0020] Among them, the first template is L-shaped, the second template includes an L-shaped portion and an upper vertical portion connected to the horizontal portion of the L-shaped portion, the height of the upper vertical portion is the same as the total thickness of the cover plate, the aluminum alloy frame and the waterproof belt, the second template is connected to the vertical portion of the first template through the lower vertical portion, the lower vertical portion is parallel to the upper vertical portion, arranged oppositely and in opposite directions.

[0021] Construction sequence:

[0022] 1. Prefabricated steel formwork, threaded rods and threaded sleeves form adjustable struts, which are fixed to the cushion layer 10 with anchor bolts 11;

[0023] 2. Set up waterproof belts, install aluminum frames, fix the slide poles and cover plates, and then install them together with the steel formwork to form them. After fixing, attach a layer of film on the top surface to facilitate cleaning after pouring.

[0024] 3. Pouring, after pouring is completed, remove the film after the concrete is finally set;

[0025] 4. Fill the seams with elastic rubber strips and the construction is completed.

[0026] The present invention has strong plasticity and can be connected to form an integrated template by replacing the aluminum alloy frame plate and the adjustable galvanized steel plate according to different types of deformation joints, which is convenient for construction.

[0027] In addition, the finished surface of the present invention is beautiful and has enhanced practicality; it is easy to construct and has increased simplicity compared to the traditional post-grooving and on-site formwork methods; the steel formwork is used and can be used as an edge protection steel plate.

[0028] In summary, the present invention adopts integrated molding, integrates various on-site construction processes into one, prefabricates the molding, has adjustability, reduces post-processing, and better guarantees the quality and convenience of construction.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
