Technical Field
[0001] The utility model relates to the technical field of building engineering, in particular to a modular tool-type expansion joint protection device. Background Art
[0002] Expansion joints are gaps reserved in structures such as buildings, bridges, and roads. They are designed to cope with structural displacements caused by temperature changes, load changes, or earthquakes. Protective devices are usually installed on expansion joints. The protective devices can effectively prevent dust and liquids from entering the expansion joints, thereby preventing these debris from corroding the materials in the expansion joints or clogging the expansion joints. They can also prevent workers and carts from tripping and bumping when passing by, providing a flat and safe surface.
[0003] At present, the protection of indoor expansion joints in building construction projects is generally carried out by nailing wooden beams under wooden boards. Although it is simple to install, it has poor durability and is easily damaged. In addition, due to the different widths of expansion joints, different expansion joints require different protective devices, which makes it difficult to use them in rotation. Utility Model Content
[0004] In view of the deficiencies existing in the prior art, the utility model provides a modular tool-type expansion joint protection device, which solves the problems in the prior art that the expansion joint protection device has poor adjustability and is difficult to rotate and use.
[0005] According to an embodiment of the utility model, a modular tool-type expansion joint protection device includes a frame, a fixing assembly and a protective steel plate. The frame includes a plurality of longitudinal beams and a plurality of transverse beams. The longitudinal beams and the transverse beams are staggered and spliced to form the frame. A plurality of threaded holes are evenly spaced on the two side walls of the longitudinal beams. Two fixing assemblies are symmetrically provided at both ends of the longitudinal beams. Each fixing assembly is detachably connected to the longitudinal beam via the threaded holes on the longitudinal beams. The fixing assembly is used to fix the frame to the expansion joint. The protective steel plate is detachably covered on the top of the frame.

Since a plurality of threaded holes are provided on the longitudinal beam, workers can adjust the distance of the fixing assembly on the longitudinal beam according to the size of the expansion joint, thereby adapting to expansion joints of different sizes. The detachable connection of the various components of the device also facilitates the processing and turnover of the components.

[0019] The technical solutions in the present utility model will be further described below with reference to the drawings and embodiments.
[0020] As Figure 1As shown in FIG. 2, an embodiment of the present utility model provides a modular tool - type expansion joint protection device, which includes a frame body, a fixing component, and a protection steel plate 3. The frame body includes a plurality of longitudinal beams 1 and a plurality of cross - beams 2. The longitudinal beams 1 and the cross - beams 2 are spliced alternately to form the frame body. A plurality of threaded holes are equidistantly arranged on both side walls of the longitudinal beam 1. Two fixing components are symmetrically arranged at both ends of the longitudinal beam 1. Each fixing component is detachably connected to the longitudinal beam 1 through the threaded holes on the longitudinal beam 1. The fixing component is used to fix the frame body to the expansion joint. The protection steel plate 3 is detachably covered on the top of the frame body. When using this device, first splice and fix a plurality of longitudinal beams 1 and cross - beams 2 to form a frame body. The longitudinal beams 1 and cross - beams 2 can be mass - prefabricated in the factory. In this embodiment, a plurality of cross - beams 2 are connected end to end, and a longitudinal beam 1 is connected between two cross - beams 2. The longitudinal beam 1 is perpendicular to the cross - beam 2 to form a frame body placed above the expansion joint. Then, install the two fixing components at the bottom of the same longitudinal beam 1 through the threaded holes on the longitudinal beam 1. At this time, the fixing components are located inside the expansion joint. In this embodiment, there are a plurality of longitudinal beams 1 on the same frame body. Set two fixing components on at least one longitudinal beam 1 according to needs, and then adjust the fixing components so that the two fixing components respectively abut against the two inner walls of the expansion joint, thereby fixing the frame body to the expansion joint and restricting the movement of the frame body on the expansion joint. Finally, cover the protection steel plate 3 on the top of the frame body, thus achieving the purpose of protecting the expansion joint. When not in use later, remove the protection steel plate 3 and release the fixing components to separate the frame body from the expansion joint. Since a plurality of threaded holes are equidistantly arranged on both side walls of the longitudinal beam 1, when protecting expansion joints of different widths, only need to adjust the screwing position of the fixing component and the longitudinal beam 1, which is very convenient and is conducive to the turnover use of this device and cost savings.
[0021] As Figure 2 shown in FIG. 3, further, each fixing component includes: a fixing block 4. One end of the fixing block 4 is provided with a through - slot, and threaded holes are arranged on both side walls of the through - slot. A screw rod 5 is threadedly connected to the side wall of the fixing block 4. An abutting plate 6 is fixedly arranged at the end of the screw rod 5 away from the fixing block 4. The two fixing blocks 4 on the same longitudinal beam 1 are symmetric with respect to the middle of the longitudinal beam 1. Specifically, the fixing block 4 has a concave structure, and threaded holes are arranged on both side walls of the groove of the fixing block 4. When installing the fixing block 4, the fixing block 4 is clamped to the bottom of the longitudinal beam 1 through the through - slot, and the threaded holes on the fixing block 4 are aligned with the threaded holes on the longitudinal beam 1. Fix the fixing block 4 and the longitudinal beam 1 through bolts, and then rotate the abutting plate 6 to screw the screw rod 5 out of the fixing block 4, and finally make the side walls of the two abutting plates 6 respectively abut against the inner walls of the adjacent expansion joints, thereby restricting the movement of the frame body.
[0022] As Figure 2 and 4As shown in the figure, further, transition blocks 7 are welded to both ends of each longitudinal beam 1. The cross-section of the transition block 7 is a right trapezoid, and inclined plates 8 adapted to the transition blocks 7 are provided at both ends of the protective steel plate 3. In this embodiment, by providing the inclined plates 8, it is convenient for equipment such as a trolley to cross the device. The transition block 7 has a right trapezoid structure, and the formed inclined surface plays an auxiliary supporting role for the inclined plate 8, avoiding bending deformation of the inclined plate 8 during long-term use.
[0023] As Figure 2 and 5 shown in the figure, further, rectangular steel plates 9 are welded to both ends of each cross beam 2. The rectangular steel plate 9 is fixedly connected to the cross beam 2, and then fixedly connected to the longitudinal beam 1 through the rectangular steel plate 9, increasing the contact area of the connection part between the two, enabling the stress between the cross beam 2 and the longitudinal beam 1 to be more evenly distributed, and at the same time providing a surface for installation and assembly, facilitating the splicing of the longitudinal beam 1 and the cross beam 2 into a frame body, and making the assembly process more efficient.
[0024] Further, each cross beam 2 and each longitudinal beam 1 are made of square steel pipes. Square steel pipes are common materials in the field of construction. They have good strength and stiffness. To make the cross beam 2 and the longitudinal beam 1 of this device, the square steel pipes only need to be cut into the required lengths.
[0025] Further, threaded holes are provided on the cross beam 2, and the protective steel plate 3 is bolted to the cross beam 2. The protective steel plate 3 is threadedly detachably connected to the cross beam 2, facilitating the removal of the protective steel plate 3 and then releasing the fixing component to separate the device from the expansion joint, and also facilitating the replacement of the protective steel plate 3.
[0026] Further, an anti-slip rubber pad is provided on one side of each abutting plate 6 away from the fixing block 4. The anti-slip rubber pad increases the friction between the abutting plate 6 and the inner wall of the expansion joint, and at the same time prevents the screw 5 from rotating, resulting in loosening of the frame body.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
