Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, and in particular to a scaffolding for highway bridge construction. Background Technology

[0002] Scaffolding is a temporary structure used in construction, providing workers with a platform and support system so they can work safely at heights. Scaffolding used in highway and bridge construction can be categorized into cup-lock scaffolding, wheel-type scaffolding, frame scaffolding, folding scaffolding, tower scaffolding, cantilever scaffolding, hoist scaffolding, self-elevating scaffolding, suspended scaffolding, and mobile scaffolding. Cantilever scaffolding extends from a building or other structure, providing workers with a working platform close to the building's outer edge.

[0003] Existing cantilever scaffolding uses tie rods that are diagonally braced between the I-beam cantilever and the wall to increase the stability of the cantilever scaffolding. Each tie rod is individually connected to the wall. Due to the uncertainty of the wall position at the connection point and the load-bearing capacity of workers moving back and forth, if one tie rod falls off, it will affect the overall stability of the scaffolding. Therefore, there is a need to provide a scaffolding for highway bridge construction to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a scaffold for highway bridge construction to solve the problem mentioned in the background art. In existing cantilever scaffolds, the tie rods are diagonally stretched between the I-beam cantilever and the wall to increase the stability of the cantilever scaffold. However, each tie rod is individually connected to the wall. Due to the uncertainty of the wall position at the connection point and the load-bearing capacity of workers walking back and forth, if one tie rod falls off, it will affect the overall stability of the scaffold.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a scaffolding for highway bridge construction, comprising:

[0007] The cantilevered scaffolding includes pre-embedded screws and tie rods. One end of the pre-embedded screw is embedded in the wall, and one end of the tie rod is attached to the end of the pre-embedded screw located outside the wall.

[0008] The first connecting assembly includes a first connecting plate, a first U-shaped slot, a U-shaped support frame, a second U-shaped slot, a second connecting plate, a third U-shaped slot, and a first bolt. The first U-shaped slot is formed on both sides of the lower end of the first connecting plate. The first connecting plate is snapped onto one end of two pre-embedded screws through the first U-shaped slot. The U-shaped support frame is fixed on both sides of the upper end of the first connecting plate. The second U-shaped slot is formed on both sides of the side of the U-shaped support frame. The second connecting plate is fixed on both sides of one end of the pre-embedded screw. The third U-shaped slot is formed on one end of the second connecting plate. The first bolt is inserted into the second U-shaped slot and the third U-shaped slot.

[0009] Furthermore, the first connecting component also includes an opening, which is formed on the side of the U-shaped support frame and located between the two second U-shaped slots.

[0010] Furthermore, the cantilever scaffold also includes I-beam cantilever poles and support poles. One end of the I-beam cantilever pole is fixed to the wall, and multiple support poles are assembled into a support frame by clamps and fixed to the I-beam cantilever pole.

[0011] Furthermore, the cantilever scaffold also includes a U-shaped connector, which is welded to the end of the I-beam cantilever rod away from the wall, and the other end of the rod is hooked onto the U-shaped connector.

[0012] Furthermore, it also includes a second connector, which includes a first waist hole, a third connecting plate, and a second waist hole. The first waist hole is located at both ends of the first connecting plate, and the second waist hole is located at both ends of the third connecting plate.

[0013] Furthermore, the second connector also includes a second bolt and a third bolt. The second bolt is inserted into the first waist hole and the second waist hole at the upper end of the third connecting plate. One end of the third bolt is fixed to the end of the I-beam cantilever rod that is fixed to the wall, and the other end is inserted into the second waist hole at the lower end of the third connecting plate.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model, through the first connecting component, installs the I-beam cantilever rod, embeds the pre-embedded screw rod into the wall, holds the first connecting plate, and from the first U-shaped slot, clamps the first connecting plate onto the pre-embedded screw rod above the outer end of the wall. At this time, the U-shaped support frame is located outside the second connecting plate at the outer end of the pre-embedded screw rod. The first bolt is inserted into the second U-shaped slot and the third U-shaped slot on the second connecting plate, and the first bolt is tightened. At this time, the two pre-embedded screw rods are connected into a whole through the first connecting component. This setting can make the two pre-embedded screw rods bear force evenly, and after being connected into a whole, the anti-detachment ability is enhanced.

[0016] II. In this utility model, by setting a second connecting component, the second bolt passes through the first waist hole and the second waist hole at the upper end of the third connecting plate, while the waist hole at the lower end of the third connecting plate is fitted onto the third bolt on the I-beam cantilever rod. The second bolt and the third bolt are tightened respectively. This setting connects the pre-embedded screw rod and the I-beam cantilever rod into a whole, further increasing the firmness of the tie rod. Attached Figure Description

[0036] Working principle:

[0037] After installing the I-beam cantilever rod 10, embed the pre-embedded screw rod 13 into the wall. Holding the first connecting plate 20, from the first U-shaped slot 21, clamp the first connecting plate 20 onto the pre-embedded screw rod 13 above the outer end of the wall. At this time, the U-shaped support frame 22 is located outside the second connecting plate 25 at the outer end of the pre-embedded screw rod 13. Insert the first bolt 27 into the third U-shaped slot 26 on the second U-shaped slot 24 and the second connecting plate 25, and tighten the first bolt 27. At this time, the two pre-embedded screw rods 13 are connected into a whole through the first connecting assembly.

[0038] This step ensures that the two pre-embedded screws 13 are subjected to uniform force, and when connected as a whole, the anti-detachment ability is enhanced.

[0043] Working principle:

[0044] On the first connecting plate 20, the second bolt 33 is passed through the first waist hole 30 beforehand. After the first connecting assembly is installed, the second waist holes 32 at both ends of the third connecting plate 31 are fitted onto the second bolt 33 and the third bolt 34, and tightened respectively.

[0045] This step connects the pre-embedded screw 13 to the I-beam cantilever 10 as a whole, further increasing the strength of the tie rod 14.
