Technical Field

[0001] The utility model relates to the technical field of bridge construction protection, in particular to a passing vehicle protection shed for road bridge construction. Background Art

[0002] In the field of bridge construction, most bridges span local roads to form a three-dimensional traffic. When constructing the upper structure of a bridge, it will affect local traffic. Risks such as welding slag falling during steel bar welding and garbage falling may harm pedestrians and vehicles. At present, for the construction of the upper structure of overpass bridges, traffic is often closed to eliminate potential safety hazards and reduce the impact of construction activities on local traffic roads. However, in the reconstruction and expansion construction of urban expressways, the road cannot be completely closed. When constructing the bridge deck anti-collision guardrail, a protection shed is usually used to provide safety protection for passing vehicles.

[0003] However, the existing protection shed cannot be moved and cannot be moved according to the construction progress.

[0004] Chinese Patent CN202321367851.0 discloses "Protection Shed for Construction of Overpass Bridge", with the publication number CN220117026U.

[0010] Preferably, the anti-slip component includes an anti-slip frame rotatably connected to the lower end of the support screw, a second support plate fixedly connected to the lower end of the anti-slip frame, and a second rubber pad fixedly connected to the lower surface of the second support plate. The second rubber pad is detachably connected to the second support plate.

[0011] With the above structural design, the area of the second support plate can be much larger than that of the first support plate, improving the anti-slip effect of the device.

[0012] Preferably, the lower end of the support screw has no thread, a rotating disc is fixedly connected to the lower end of the support screw, a fixing column is sleeved on both the rotating disc and the support screw, and the fixing column is fixedly connected to the anti-slip frame.

[0013] With the above structural design, the structure is simple and has strong supporting force. The second support plate can descend or rise without rotating along with the support screw.

[0014] Preferably, a light strip is fixedly connected to the support leg, and adjacent light strips are electrically connected by wires.

[0015] With the above structural design, it provides lighting for vehicles at night, and also plays a warning role, reducing the probability of vehicles hitting the protection shed.

[0023] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 , the present utility model provides a technical solution: a passing vehicle protection shed for road and bridge construction, including a shed top 1, a plurality of support legs 2 fixedly connected to the shed top 1, and moving wheels 3 fixedly connected to the lower ends of the support legs 2. A fixing device for fixing the support legs 2 on the road surface is provided on the support legs 2. The fixing device includes a sleeve 41 fixedly connected to the support leg 2, a support screw 42 threadedly passing through the sleeve 41, and an anti-slip assembly fixedly connected to the lower end of the support screw 42.

[0024] A diagonal brace 9 is provided between adjacent support legs 2. For the convenience of assembling and disassembling the device, the diagonal brace 9 is fixedly connected to the support leg 2 by bolts.

[0025] The shed top 1 includes a plurality of triangular main beams 11, cross beams 12 connecting the main beams 1, and steel plates 13 provided on the main beams 11. For the convenience of assembling and disassembling the device, the main beams 11 are fixedly connected to the cross beams 12 by bolts, the steel plates 13 are fixedly connected to the main beams 11 and the cross beams 12 by bolts, and the main beams 11 are fixedly connected to the support legs 2 by bolts and triangular braces.

[0026] The anti-slip assembly includes a first support plate 51 fixedly connected to the lower end of the support screw 42, and a first rubber pad 52 fixedly connected to the lower surface of the first support plate 51. The first rubber pad 52 is detachably connected to the first support plate 51, and the first rubber pad 52 is fixedly connected to the first support plate 51 by bolts.

[0027] In the embodiment, the support screw rod 42 adopts a bolt structure.

[0028] A light strip 8 is fixedly connected to the support leg 2, and adjacent light strips 8 are electrically connected through an electric wire 81.

[0029] When the device is in use, first, the staff uses bolts and triangular braces to assemble and fix the shed roof 1 and the support legs 2, then the staff uses bolts to fix the diagonal braces 9 between adjacent support legs 2, then the staff moves the device under the construction bridge, and then the staff uses a wrench to rotate the support screw rod 42 until the first rubber pad 52 on the first support plate 51 is in close contact with the ground, and the fixing of the device is completed.

[0030] Embodiment Two:

[0031] As Figure 3 、 Figure 4 shown, Embodiment Two is different from Embodiment One. The anti-slip assembly includes an anti-slip frame 61 rotatably connected to the lower end of the support screw rod, a second support plate 62 fixedly connected to the lower end of the anti-slip frame 61, and a second rubber pad 63 fixedly connected to the lower surface of the second support plate 62.
