Description

Technical Field

[0001] This utility model relates to the field of bridge support technology, specifically a simple support for the rapid assembly of urban overpasses during dismantling. Background Technology

[0002] With the continuous improvement of economic level and the continuous progress of science and technology, bridge structures have developed rapidly. When bridges are constructed using the scaffolding method, temporary scaffolding is built to bear the bridge load. This scaffolding is usually constructed using steel pipes. Even bridges with a height of less than 3 meters require scaffolding, so the cost of scaffolding must be calculated. The general requirements for bridge construction scaffolding are that it has sufficient strength and rigidity to meet the requirements of the bridge's self-weight and construction loads, and that the bearing capacity of the scaffolding foundation meets the requirements.

[0003] However, the existing simple scaffolding for quick assembly and dismantling of urban overpasses has the following problems during use: the steel column connections of the traditional scaffolding system are welded, which requires large cutting and generates large losses, increasing costs for later dismantling; while the installation speed of the disc buckle is slow and the cost is high.

[0006] This technical solution provides a simple support frame for quick assembly during the dismantling of urban overpasses. The top and bottom of the steel pipe column are welded with connecting steel plates, and the outer wall of the connecting steel plates is welded with reinforcing ribs.

[0007] This technical solution provides a simple support frame for quick assembly during the dismantling of urban overpasses, wherein a horizontal steel plate is welded between the H-beam and the I-beam.

[0008] This technical solution provides a simple support for the quick assembly of a dismantling urban overpass. The installation mechanism includes a movable groove and a movable column. The movable groove is provided inside the steel pipe column, which has a through arc-shaped installation groove. A positioning block is provided inside the movable groove, which has a through positioning groove. The movable column is installed on the outer wall of the positioning block, which has a through movable groove.

[0013] Compared with the prior art, this utility model provides a simple support frame for quick assembly during the dismantling of urban overpasses, which has the following beneficial effects:

[0014] 1. This utility model allows for easy installation and disassembly of the inclined support steel plate by engaging and separating the rotatable positioning screw. By pushing the positioning block into the movable groove, the positioning block retracts into the movable groove. At this point, the inclined support steel plate is separated from the arc-shaped mounting groove, thus completing the disassembly. This structure facilitates installation and disassembly and improves construction efficiency.

[0015] 2. This utility model moves the diagonal bracing steel plate from back to front at the arc-shaped mounting groove inside the steel pipe column to the compression positioning block. The positioning block is compressed and tightened, causing the positioning block to drive the movable column to insert into the movable groove and compress the rigid spring. At this time, after the diagonal bracing steel plate moves to the positioning groove and aligns with the positioning block, the rigid spring's own elastic force drives the positioning block to insert into the positioning groove, initially positioning the diagonal bracing steel plate in the arc-shaped mounting groove of the steel pipe column. Then, the operator can rotate the positioning screw to engage with the rigid spring and the internal thread groove of the diagonal bracing steel plate until the rotating positioning screw moves and penetrates into the positioning block. This structure facilitates the quick installation and fixation of the diagonal bracing steel plate in the position of the steel pipe column. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1, such as Figure 1-2 As shown, this utility model provides a technical solution: a simple support frame for quick assembly and dismantling of urban overpasses, comprising steel pipe columns 1, diagonal bracing steel plates 7, and H-beam steel plates 14. The top of the H-beam steel plate 14 is welded to the steel pipe column 1, and the top of the steel pipe column 1 is welded to an I-beam 2. Connecting steel plates 3 are welded to the top and bottom of the steel pipe column 1, and reinforcing ribs 4 are welded to the outer wall of the connecting steel plates 3. A horizontal steel plate 5 is welded between the H-beam steel plate 14 and the I-beam 2. This is achieved by laying six rows of steel pipes on the road surface. Bridge deck ancillary facilities are installed at the top of column 1 and I-beam 2. These facilities include anti-throw nets and bridge deck railings. H-beam steel plates 14 are used as the base for the steel pipe column 1, while the top of the I-beam 2 is supported, which facilitates pre-welding, movement, and dismantling. The bridge deck railings and anti-throw nets are installed at the top of the steel pipe column 1. Because the ancillary facilities are relatively light, the overall rigidity of the bridge deck is not reduced when the bridge deck ancillary facilities are dismantled. The anti-throw nets and railings can be removed using a wrench and a handheld cutting machine.

[0024] Example 2, as Figure 1-5As shown, this utility model provides a technical solution: a simple support frame for quick assembly and dismantling of urban overpasses, including a steel pipe column 1 with an arc-shaped installation groove 6 on its outer wall, and a diagonal bracing steel plate 7 for support inside the arc-shaped installation groove 6. The outer wall of the diagonal bracing steel plate 7 has a positioning groove 8. An installation mechanism for fixing the position of the diagonal bracing steel plate 7 within the steel pipe column 1 is provided inside the steel pipe column 1. The installation mechanism includes a movable groove 9 and a movable column 10. The movable groove 9, penetrating the arc-shaped installation groove 6, is provided inside the movable groove 9, penetrating the positioning groove 8. A movable column 10, penetrating the interior of the movable groove 9, is installed on the outer wall of the positioning block 11. A rigid spring 12, connected to the positioning block 11 and the inner wall of the movable groove 9, is sleeved on the outer wall of the movable column 10. A rigid spring 12, penetrating the arc-shaped installation groove 6, is provided inside the rigid spring 12, penetrating the diagonal bracing steel plate 7. The positioning screw 13 extends into the positioning block 11 through an internal threaded groove. The positioning screw 13 is threadedly connected to the threaded groove on the inner wall of the inclined support steel plate 7. The inclined support steel plate 7 moves from back to front from the arc-shaped mounting groove 6 inside the steel pipe column 1 to press the positioning block 11. As a result, the positioning block 11 is compressed and tightened. The positioning block 11 then drives the movable column 10 to insert into the movable groove 9 and press the rigid spring 12. At this time, the inclined support steel plate 7 moves to the positioning groove 8 and aligns with the position of the positioning block 11. Under the elastic force of the rigid spring 12, the positioning block 11 is inserted into the positioning groove 8, which initially positions the inclined support steel plate 7 in the arc-shaped mounting groove 6 of the steel pipe column 1. Then, the operator can rotate the positioning screw 13 to engage with the internal threaded groove of the rigid spring 12 until the positioning screw 13 moves and penetrates into the positioning block 11. This structure facilitates the quick installation and fixation of the inclined support steel plate 7 in the position of the steel pipe column 1.

[0025] Working principle: First, the operator can weld and install the steel pipe column 1 to the I-beam 2 and H-beam plate 14. Then, the operator can lay the bridge deck ancillary facilities above the I-beam 2, including anti-throw netting and bridge deck railings. The steel pipe column 1 is supported by the H-beam plate 14, while the I-beam 2 is supported at the top, facilitating pre-welding, movement, and dismantling. The top of the steel pipe column 1 includes bridge deck railings and anti-throw netting. When it is necessary to dismantle this support, due to the ancillary facilities... The structure is relatively lightweight, and the overall rigidity of the bridge deck is not reduced when dismantling the bridge deck ancillary facilities. The anti-throw net and guardrail can be removed using a wrench and a handheld cutting machine. When it is necessary to remove the diagonal bracing steel plate 7, the positioning screw 13 can be rotated to engage with the diagonal bracing steel plate 7 and then the positioning block 11 can be pushed into the movable groove 9 to retract into the movable groove 9. At this time, the diagonal bracing steel plate 7 can be pushed to separate from the arc-shaped installation groove 6 to complete the removal. This structure is easy to install and dismantle, improving construction efficiency.

[0026] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
