[0002] With the development of modern construction technology, ultra-thick floor slabs are becoming more and more widely used. During the construction process, it is necessary to reserve openings of various shapes and sizes on the floor slabs. As a common and crucial construction content, the size of rectangular openings is particularly important in order to ensure the accuracy of the reserved opening position and size.

[0003] However, the rectangular openings in ultra-thick floor slabs require secondary drilling for the subsequent installation of pipes, cables or other equipment, as well as after concrete pouring, which delays the construction schedule and increases costs, and also leads to safety hazards and poor integrity.

[0004] Therefore, the known floor opening processing methods have the above-mentioned inconveniences and problems. Utility Model Content

[0005] The purpose of the utility model is to provide a safe and reliable device for reserving rectangular openings in ultra-thick floor slabs.

[0006] To achieve the above objectives, the technical solution of the present invention is:

[0007] A device for preserving rectangular openings in ultra-thick floor slabs, comprising a rectangular frame, a cover plate, and a bottom plate, is characterized in that:

[0008] The rectangular frame is set according to the size of the reserved rectangular opening;

[0009] The cover plate is a rectangular plate, and is provided with holes at both ends of the diagonal line to match the size of the rectangular opening, so that the cover plate can be movably arranged on the upper end of the rectangular frame;

[0010] The bottom plate is matched with the size and holes of the cover plate so that the bottom plate can be movably arranged at the lower end of the rectangular frame;

[0011] Among them: the holes of the cover plate and the bottom plate are matched, and a screw rod is set to pass through the hole. Both ends of the screw rod are provided with mountain-shaped clips, so that the cover plate and the bottom plate are respectively fastened to the upper and lower ends of the rectangular frame to achieve a rectangular hole reservation device.

[0012] The super-thick floor rectangular opening reservation device of the present invention can also be further implemented by adopting the following technical measures.

[0013] The aforementioned super-thick floor rectangular opening reservation device, wherein the rectangular frame adopts a wooden formwork.

[0014] The aforementioned device for preserving rectangular openings in ultra-thick floor slabs, wherein the four sides of the cover plate are each 5 cm larger than the rectangular frame.

[0015] After adopting the above technical solution, the super-thick floor rectangular opening reservation device of the utility model has the following advantages:

[0016] 1. The device has a simple structure and is easy to manufacture;

[0017] 2. It reduces the amount of work required for later hole openings, increases construction speed, saves a lot of manpower and material resources, and effectively reduces costs;

[0018] 3. The operation is simple, and the reserved openings of ultra-thick floor slabs can be formed into a square and regular shape at one time, achieving a beautiful effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 This is a schematic diagram of the use status of the device for reserving rectangular openings in ultra-thick floor slabs according to an embodiment of the utility model;

[0020] Figure 2 This is a schematic diagram of the cover structure of an embodiment of the present utility model. DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the embodiments and the accompanying drawings.

[0022] Example 1

[0023] Please refer to Figure 1 and Figure 2 The super-thick floor rectangular opening reservation device of the present invention includes a cover plate 5.

[0024] The cover plate 5 is a rectangular wooden formwork with circular holes 8 at both diagonal ends. The corresponding floor slab formwork 6 also has holes at corresponding locations. The rectangular frame 4 is made of wooden formwork according to the dimensions of the reserved rectangular opening. The cover plate 5 is 5 cm larger than the rectangular frame on all four sides to ensure that it completely covers the upper end of the rectangular frame 4. A threaded rod 1 is passed through the upper cover plate 5 and the bottom formwork 6. The ends of the threaded rod 1 are screwed into the gable clamps 3 and nuts 2 to lock and secure the rectangular frame.

[0025] Example 2

[0026] The method of using the rectangular opening reservation device for ultra-thick floor slabs of the utility model:

[0027] The hole reservation device is placed at the rectangular hole position of the floor slab. After the concrete structure 7 is poured, the mountain-shaped clamps and nuts at both ends of the screw rod of the hole reservation device are loosened and the template is removed to form the corresponding rectangular hole.

[0028] The utility model has substantial characteristics and significant technological progress. The ultra-thick floor rectangular opening reservation device of the utility model is easy to obtain materials, and leftover wooden formwork, threaded rods, etc. on the construction site can be used. The processing cost is low, the processing is convenient, the materials can be recycled, and the positioning is accurate.

[0029] The above embodiments are intended only to illustrate the present invention and are not intended to limit the present invention. Persons skilled in the art may make various modifications or variations without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions are intended to fall within the scope of the present invention and are defined by the claims.
