Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a reusable protective device for floor expansion joints. Background Technology

[0002] With the increasing mechanization of construction, the number of machines operating on building floors is growing. Mechanical operations require smooth roads, and floor expansion joints (also known as growth joints) are essential passageways for these machines. These joints need to be sealed with appropriate cover plates to allow for their passage. Currently, wooden formwork structures are commonly used to seal floor expansion joints. However, due to the surge in the number of machines used in construction, frequent tipping and crushing of the wooden cover plates leads to their rapid damage, hindering machine passage and construction progress. Damage to the cover plate structure can also pose safety hazards such as objects falling from upper and lower floors. Therefore, wooden cover plates have poor durability and require frequent maintenance, resulting in high maintenance costs. Furthermore, existing protective cover plates are of fixed specifications and cannot be adjusted according to the length of the floor expansion joint, lacking versatility. Therefore, a reusable protective device for floor expansion joints needs to be developed. Utility Model Content

[0003] The purpose of this utility model is to provide a reusable protective device for floor expansion joints, thereby solving the technical problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a reusable protective device for floor expansion joints, comprising a main board with a closed cover plate. A fixing limiting mechanism is respectively provided at the bottom of the main board near both ends, and each fixing limiting mechanism is used to abut against the inner wall of the floor expansion joint. Two standard auxiliary plates are symmetrically connected to both ends of the main board, and an adjusting plate is respectively connected to the end of each of the two standard auxiliary plates away from the main board. Two connecting members are symmetrically fixed at the bottom ends of the main board, the bottom ends of the two standard auxiliary plates, and the bottom of the two adjusting plates near the standard auxiliary plates. The corresponding connecting members between the main board and the standard auxiliary plates, and between the standard auxiliary plates and the adjusting plates, are respectively connected by connecting rods.

[0006] Furthermore, each of the fixed limiting mechanisms includes two fixed seats fixedly disposed at the bottom of the main board of the closed cover plate. The fixed seat has a threaded hole in the middle and a limiting bolt threadedly connected thereto. One end of the limiting bolt abuts against the inner wall of the floor expansion joint, and a limiting nut threadedly connected thereto is fitted on the limiting bolt near the outer wall of the fixed seat.

[0007] Furthermore, each of the connecting components includes a connecting tube, and the two ends of the connecting rod are slidably inserted into the two corresponding connecting tubes. Each connecting tube has a through hole on its side wall and a fixing nut is fixedly installed on the outside of the through hole. The fixing nut is provided with a fixing bolt that is threadedly connected to it and used to fix the connecting rod.

[0008] Furthermore, the main body of the closed cover plate has a length of 1500mm, a width of 400mm, and a thickness of 5mm; the width and thickness of each of the standard auxiliary plates and each of the adjustment plates are the same as the width and thickness of the main body of the closed cover plate; the length of each of the standard auxiliary plates is 600mm, and the length of each of the adjustment plates is 300mm.

[0009] Furthermore, the main cover plate, each of the standard auxiliary plates, and each of the adjustment plates are all made of embossed steel plates.

[0010] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0011] The main body of the closed cover plate, the standard auxiliary plates, and the adjustment plates of the protective device constituted by this utility model are all made of embossed steel plate. The entire protective device has high structural strength and applicability, and can be reused repeatedly without frequent maintenance. It can avoid the safety hazard of falling objects from upper and lower floors caused by damage to the protective cover plate, and provides an effective safety guarantee for the construction site working environment.

[0012] This invention utilizes a fixing and limiting mechanism at the bottom of the main cover plate to abut against the two inner walls of the floor expansion joint, thereby limiting the main cover plate and preventing it from wobbling after placement. Furthermore, the extension length relative to the fixing seat can be adjusted by rotating the limiting screw to accommodate the limiting requirements of the main cover plate on floor expansion joints of varying widths.

[0013] In addition, the distance between the two standard auxiliary plates and the main board of the closed cover plate, as well as the distance between the two adjusting plates and the two standard auxiliary plates, can be easily adjusted, so that the entire protective cover plate structure can adapt to the shielding and protection needs of floor expansion joints of different lengths.

The bottom of the main board 1 near both ends is provided with a fixing limiting mechanism, and each fixing limiting mechanism is used to abut against the two inner walls of the floor expansion joint 2.

[0021] In this embodiment, each of the fixed limiting mechanisms includes two fixed seats 3 that are fixedly welded to the bottom of the main board of the closed cover plate 1. Each fixed seat 3 has a threaded hole in its center and a limiting bolt 4 threadedly connected to it. One end of each limiting bolt 4 abuts against the two inner walls of the floor expansion joint 2, thereby limiting the closed cover plate 1 and preventing it from shaking freely after placement. Furthermore, the extension length of the limiting bolt 4 relative to the fixed seat 3 can be adjusted by rotating it to accommodate the limiting requirements of the closed cover plate 1 on floor expansion joints of different widths. A limiting nut 5 threadedly connected to the limiting bolt 4 is fitted near the outer wall of the fixed seat 3, and the limiting nut 5 can be used to fix the adjusted limiting bolt 4.

[0022] Two standard auxiliary plates 6 are symmetrically connected to both ends of the main board 1 of the sealing cover. Adjustment plates 7 are respectively connected to the ends of the two standard auxiliary plates 6 furthest from the main board 1. Two connecting pieces are symmetrically fixed to the bottom ends of the main board 1, the bottom ends of the two standard auxiliary plates 6, and the bottom ends of the two adjustment plates 7 closest to the standard auxiliary plates 6. The corresponding connecting pieces between the main board 1 and the standard auxiliary plates 6, and the corresponding connecting pieces between the standard auxiliary plates 6 and the adjustment plates 7, are connected by connecting rods 8.

[0023] Specifically: Each of the connecting components includes a connecting pipe 9, and the sealing edges of each connecting pipe 9 are fixedly installed at the bottom of the main board 1 of the closed cover plate, the two standard auxiliary plates 6, and the two adjusting plates 7 by welding. The two ends of the connecting rod 8 are slidably inserted into the corresponding two connecting pipes 9. Each connecting pipe 9 has a through hole on its side wall, and a fixing nut 10 is fixedly installed on the outside of the through hole by welding. A fixing bolt 11 is installed on the fixing nut 10 and is threaded to it for fixing the connecting rod 8.

[0024] This invention achieves effective adjustment of the distance between the standard auxiliary plate and the main board of the closed cover plate, and between the adjusting plate and the standard auxiliary plate by adjusting the insertion depth of the connecting rod in the corresponding connecting pipe. The connecting rod is fixed by fixing bolts, so that the adjusted main board of the closed cover plate, the two standard auxiliary plates and the two adjusting plates are fixedly connected as a whole.

[0025] In this embodiment, the main board 1 of the sealing cover has a length of 1500mm, a width of 400mm, and a thickness of 5mm. The width and thickness of each of the standard auxiliary plates 6 and each of the adjustment plates 7 are the same as the width and thickness of the main board 1 of the sealing cover; the length of each of the standard auxiliary plates 6 is 600mm, and the length of each of the adjustment plates 7 is 300mm.

[0026] The main board 1 of the closed cover, each of the standard auxiliary plates 6 and each of the adjustment plates 7 are all made of embossed steel plates. The entire protective device has high structural strength, good applicability and can be reused repeatedly without frequent maintenance. It can avoid the safety hazard of falling objects from upper and lower floors caused by damage to the protective cover, and provides effective safety protection measures for the construction site working environment.

[0027] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
