Description

Technical Field

[0001] This utility model relates to the field of protective cover technology, specifically to a temporary protective cover for expansion joints in building floor slabs. Background Technology

[0002] Expansion joints in building floor slabs are long, narrow gaps. During construction, materials from the upper floor can easily fall through these joints, potentially injuring workers on the lower floor. Installing protective covers at the expansion joints can provide protection. Traditionally, expansion joints are simply protected by placing wooden boards, but these boards can easily move during construction, also creating safety hazards. Utility Model Content

[0003] In view of the safety hazards caused by the easy movement of existing wooden boards in expansion joints, a temporary protective cover for expansion joints that prevents the wooden boards from moving is provided to solve the above problems.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a temporary protective cover for expansion joints of building floor slabs, comprising a plate body with a through structure, a first limiting plate and a second limiting plate, with baffles provided at both ends of the plate body, the first limiting plate and the second limiting plate being respectively located at both ends of the plate body and slidably connected to the plate body; a first limiting block is provided at the end of the first limiting plate away from the second limiting plate, and a second limiting block is provided at the end of the second limiting plate away from the first limiting plate.

[0005] In an improvement to this utility model, threaded holes are provided at both ends of the upper surface of the plate, and bolts are provided in the threaded holes.

[0006] In an improvement to this utility model, the first limiting plate and the second limiting plate are provided with grooves in the axial direction, and the position of the grooves corresponds to the bolt.

[0007] In an improvement to this utility model, a third limiting block and a fourth limiting block are provided at both ends of the lower end face of the plate.

[0008] In an improvement to this utility model, a connecting groove is provided on one side of the plate and a hanging groove is provided on the other side.

[0009] The technical solution provided by this utility model has the following advantages compared with the known prior art: A temporary protective cover for expansion joints in building floor slabs includes a through-type plate, a first limiting plate, and a second limiting plate. Baffles are provided at both ends of the plate. The first and second limiting plates are slidably connected to the plate at both ends. A first limiting block is provided at the end of the first limiting plate away from the second limiting plate, and a second limiting block is provided at the end of the second limiting plate away from the first limiting plate. With this structure, during use, when placed on two structural beams, the first and second limiting blocks hook onto the exterior of the two beams, preventing the cover from moving and falling, thus improving operational safety.

Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0013] The present invention will be further described below with reference to the embodiments.

[0014] Reference Figure 1-4This utility model discloses a temporary protective cover for expansion joints in building floor slabs, comprising a through-type plate 1, a first limiting plate 2, and a second limiting plate 3. The first limiting plate 2 and the second limiting plate 3 are respectively located at both ends of the plate 1 and are slidably connected to the plate 1. A first limiting block 21 is provided at the end of the first limiting plate 2 away from the second limiting plate 3, and a second limiting block 31 is provided at the end of the second limiting plate 3 away from the first limiting plate 2. In use, it is placed on two structural beams, and the first limiting block 21 and the second limiting block 31 hook onto the exterior of the two structural beams, preventing the cover from moving and falling, thus improving operational safety.

[0015] Preferably, under normal circumstances, the pressure in the middle of the protective cover is relatively large. Therefore, the first limiting plate 2 and the second limiting plate 3 will not move unplanned, causing the protective cover to fall off the structural beam. However, for further safety considerations, threaded holes are provided at both ends of the upper surface of the plate 1, and bolts 11 are installed in the threaded holes. After the protective cover is placed on the structural beam, the lower end of the bolt 11 presses against the first limiting plate 2 and the second limiting plate 3 through the cooperation of the bolts 11 and the threaded holes, preventing the limiting plates 11 and 2 from sliding freely on the plate 1. Threaded holes are provided at both ends of the upper surface of the plate 1, and bolts 11 are installed in the threaded holes.

[0016] Preferably, it is understood that after the bolt 11 repeatedly presses the first limiting plate 2 and the second limiting plate 3, the area around the bolt 11 will bulge, thus preventing the first limiting plate 2 and the second limiting plate 3 from sliding smoothly within the plate body 1. The first limiting plate 2 and the second limiting plate 3 are provided with grooves 4 in the axial direction, and the position of the grooves 4 corresponds to the bolt 11. When the bolt 11 is tightened, the lower end of the bolt 11 is pressed against the bottom of the groove 4, thus preventing the corresponding positions of the first limiting plate 2 and the second limiting plate 3 from bulging.

[0017] Preferably, the lower end face of the plate 1 is provided with a third limiting block 12 and a fourth limiting block 13 at both ends; the first limiting block 21 and the third limiting block 12 are conveniently located on both sides of a structural beam, and the second limiting block 31 and the fourth limiting block 13 are respectively located on both sides of another structural beam. This arrangement will be safer.

[0018] Preferably, the plate 1 has a connecting groove 14 on one side and a hanging groove 15 on the other side. The first limiting plate 2 and the second limiting plate 3 have axial grooves 4, and the position of the grooves 4 corresponds to the bolts 11. The length of the structural beam is generally about 1.5 meters to 3 meters. To facilitate carrying the protective cover, the protective cover can be designed to be spliced. Specifically, the plate 1 in one protective cover is connected to the plate 1 in another adjacent protective cover through the connecting groove 14 and the hanging groove 15. In this way, multiple protective covers will not move laterally after being spliced ​​together.

[0019] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
