[0031] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] Reference Figures 1 to 6 As shown, the present invention provides a floor slab pipe opening hanging hole supporting device, comprising: a base pipe 1, a top rod 2, a driving structure, a support tray 4 and a blocking member 5.

[0034] The base pipe 1 is arranged vertically. A perforation is provided on the pipe wall of one side of the base pipe 1.

[0035] The lower end of the push rod 2 is movably inserted into the base pipe 1 .

[0036] The driving structure includes a rack 31, a support plate 32 and a gear 33. The rack 31 is fixedly mounted on the outside of the lower end of the top rod 2. The support plate 32 is arranged vertically, and the lower end of the support plate 32 is flippably and detachably mounted on the outside of the base pipe 1. The gear 33 is rotatably mounted on the side of the support plate 32 facing the base pipe 1. After the support plate 32 is flipped upward, one side of the gear 33 extends into the through hole and meshes with the rack 31. After the gear meshes with the rack, the position of the gear is locked by a locking member.

[0037] The tray 4 is fixed to the upper end of the top rod 2. A notch 40 is provided on one side of the tray 4. Sockets are provided on the inner walls on opposite sides of the notch 40. Clamps 41 are movably inserted in the sockets. An elastic member 42 is installed in the sockets for pushing the clamps to clamp the two clamps to the lower end of the pipe in the pipe hole of the floor.

[0038] The blocking member 5 blocks between the lower end of the pipe 7 and the lower end of the pipe hole and is placed on the two clamping plates 41 .

[0039] The floor slab pipe hole hanging hole support device of the present invention can be applied to various pipe hole support of different diameters at different storey heights, while also avoiding waste of materials, being both environmentally friendly and practical, preventing waste of resources, and greatly improving the construction efficiency and construction molding quality of the on-site pipe hanging hole. The floor slab pipe hole hanging hole support device of the present invention is detachable and easy to transport.

[0040] As a preferred embodiment, the support plate 32 is provided with an axial hole. A transmission shaft 38 is rotatably mounted in the axial hole. One end of the transmission shaft 38 is transmission-connected to the gear 33 via a gear assembly.

[0041] See also Figure 3 and Figure 4 The gear assembly includes a first bevel gear 391 and a second bevel gear 392. Specifically, the gear 33 and the second bevel gear 392 are coaxially connected through a fixed shaft. The fixed shaft is rotatably mounted on the side of the support plate facing the base pipe. One end of the transmission shaft is coaxially connected to the first bevel gear 391. The first bevel gear 391 is meshed with the second bevel gear 392. The construction personnel rotate the transmission shaft to drive the gear to rotate, thereby driving the top rod to rise and fall along the axial direction of the base pipe.

[0042] In this embodiment, the outside of the base pipe 1 is connected to a sleeve arranged along the width direction of the rack 31. A rotating shaft 36 is rotatably mounted in the sleeve. An adapter plate 34 is connected to the end of the rotating shaft 36. The adapter plate 34 has a first side and a second side opposite to each other. The sleeve is connected to the lower part of the first side of the adapter plate 34. The support plate 32 is connected to the upper part of the first side of the adapter plate 34. The second side of the adapter plate 34 extends to the side of the base pipe 1 facing away from the through hole and is connected to a limit rod 37. The limit rod 37 abuts against the side of the base pipe 1 facing away from the through hole.

[0043] In this embodiment, see Figure 2 and Figure 3 ,like Figure 2 The supporting plate is flipped upwards so that the gear is engaged with the rack of the top rod, and the limiting rod is away from the base pipe to form a gap between the limiting rod and the base pipe. The locking piece is inserted in the gap to prevent the supporting plate from rotating.

[0044] When the gear and the rack need to be separated, the locking piece is removed and the support plate is flipped down, so that the gear and the rack are separated, and then the push rod and the base pipe can be disassembled and separated. Since the rotating shaft 36 can be movably inserted into the shaft sleeve, the support plate can also be separated from the base pipe and transported separately.

[0045] In this embodiment, the limiting rod 37 is connected to an operating rod a. The other end of the transmission shaft 38 is connected to a handle b.

[0046] The bottom end of the base pipe 1 is connected to a support base 11. The support base and the outside of the base pipe 1 are obliquely connected with a first oblique support 12.

[0047] A second oblique support 43 is obliquely connected between the support tray 4 and the top rod 2. The elastic member is a plurality of coil springs.

[0048] The present invention provides a construction method of a floor slab pipe opening hanging hole support device, comprising the following steps:

[0049] S1: The base pipe 1 is vertically arranged below the pipe opening of the floor slab so that the notch 40 of the support tray 4 is aligned with the pipe opening.

[0050] S2: The support plate 32 is flipped upwards, and one side of the gear 33 extends into the through hole of the base pipe 1 and engages with the rack 31 on the push rod 2.

[0051] After the gear is meshed with the rack, the locking piece is inserted between the limiting rod and the base pipe to lock the support plate.

[0052] S3: Rotate the gear 33 to make the top rod 2 rise along the axial direction of the base pipe 1, so that the support plate 4 is pressed against the bottom of the floor.

[0053] S4: insert the pipe into the pipe hole, and spread the two clamping plates to set the lower end of the pipe between the two clamping plates, so that the two clamping plates are clamped on the lower end of the pipe.

[0054] S5: The plugging piece 5 is embedded between the lower end of the pipe 7 and the lower end of the pipe opening and placed on two clamping plates, so that a pouring space A for pouring and filling concrete is formed between the inner wall of the pipe opening and the plugging piece 5 and the outer wall of the pipe.

[0055] After the pouring space is formed, concrete is poured into the pouring space to form a complete patching structure between the pipe and the floor slab to repair the pipe hole in the floor slab.

[0056] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the present application.
