Description

Technical Field

[0001] The utility model relates to the technical field of operating platforms, in particular to an operating platform for the joint operation of laminated walls. Background Technique

[0002] In the joint operation between two adjacent wall panels of precast double-skin laminated walls, a scissor lift or a boom lift is usually used as the operating platform. The prerequisite for its use is that the reserved width from the outer wall of the precast double-skin laminated wall to the slope should reach more than 2.5 m. The conventional operation method is to consider reserving enough width from the outer wall to the toe line during the design of the foundation pit excavation, and then backfill the reserved width to the top of the raft foundation and harden the ground to form a freely movable passage. This method is the most widely used and common solution at present.

[0003] However, due to the influence of the land use scope and surrounding buildings, the width between the outer wall and the raft foundation is only 500 mm. The operability of using a scissor lift or a boom lift is restricted by the on-site basic conditions. The width from the outer wall of the laminated wall to the edge of the raft foundation is small, and there is not enough reserved width for the scissor lift or boom lift to construct, resulting in the inability to orderly connect the construction process and the difficulty in achieving the construction period target, which affects the construction efficiency of the laminated wall. Therefore, there is an urgent need for an operating platform for the joint operation of laminated walls to solve the above problems. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides an operating platform for the joint operation of laminated walls, including a first column, a second column, a cross beam and a counterweight. The heights of the first column and the second column are higher than the height of the laminated wall. The first column and the second column are connected by the cross beam, and the three enclose a receiving cavity for the laminated wall to pass through. The distance between the first column and the second column is greater than the thickness of the laminated wall. A plurality of construction platforms are arranged on the second column at intervals along the vertical direction. The distance between the topmost construction platform and the top of the laminated wall is not greater than 2 m. The counterweight is arranged on the first column.

[0005] Furthermore, limiting rollers are arranged on one side of the first column and the second column facing the receiving cavity, and the axial direction of the limiting rollers is parallel to the longitudinal direction.

[0006] Furthermore, the protruding length of the limiting rollers on the second column is less than the distance between the outer wall of the laminated wall and the edge of the raft foundation.

[0007] Furthermore, the cross beam is a steel truss cross beam, and the first column and the second column are respectively fixedly connected to the bottom of the steel truss cross beam.

[0008] Further, the cross beam includes two cross beam units, the first upright post and the second upright post are respectively connected to one of the cross beam units, and the two cross beam units are telescopically connected.

[0009] Further, a vertical channel is provided in the second upright post. The vertical channel is located on one side of the construction platform. A plurality of tread bars are arranged at intervals along the vertical direction in the vertical channel, and each tread bar is fixedly connected to the second upright post.

[0010] Further, the second upright post is a steel truss upright post, which includes a vertical support assembly and a plurality of horizontal support assemblies arranged at intervals along the vertical direction of the vertical support assembly. The vertical support assembly includes a plurality of vertical rods distributed in a square shape, and each vertical rod is connected to the horizontal support assembly layer by layer. The construction platform is arranged corresponding to the horizontal support assemblies of the second upright post one by one.

[0011] Further, a plurality of diagonal braces are provided between two adjacent vertical rods.

[0012] Further, a hoisting position for hoisting is provided on the cross beam.

[0013] Further, an anti-corrosion layer is provided on the first upright post, the second upright post and the cross beam.

[0014] Due to the adoption of the above technical solutions, the present utility model has the following beneficial effects compared with the prior art:

[0015] 1) The operation platform provided by the present utility model can be used when the distance between the outer wall of the composite wall and the edge of the raft foundation is small. The second upright post can be partially placed on the raft foundation and partially cantilevered, and the balance of the operation platform is realized through the counterweight on the first upright post. The required site is small, which solves the problem that the operation platform cannot be set due to limited site, reduces the influence of on-site conditions on the investment of the operation platform, increases the applicability of the operation platform, and thus shortens the construction period and cost investment.

[0016] 2) For the operation platform provided by the present utility model, limit rollers are provided on the first upright post and the second upright post, which is convenient for the operation platform to be lifted and lowered smoothly along the composite wall during the hoisting process without damaging the composite wall.

[0026] Example 1

[0027] As shown in the attached drawings of the specification Figures 1-3 As shown, this embodiment provides an operating platform for the splicing operation of a composite wall, including a first column 3, a second column 4, a cross beam 5, and a counterweight 6. The heights of the first column 3 and the second column 4 are higher than the height of the composite wall 1. The first column 3 and the second column 4 are connected by the cross beam 5, and the three enclose a receiving cavity for the composite wall 1 to pass through. The distance between the first column 3 and the second column 4 is greater than the thickness of the composite wall 1. A plurality of construction platforms 7 are arranged on the second column 4 at intervals in the vertical direction. The distance between the uppermost construction platform 7 and the top of the composite wall 1 is not greater than 2 m. The counterweight 6 is arranged on the first column 3.

[0028] Specifically, the composite wall 1 is arranged on the raft foundation 2. The composite wall 1 can be a precast double-skin composite wall. The operating platform of the present application is suitable for operating on the outer joint of the composite wall 1. The distance between the outer side of the composite wall 1 and the edge of the raft foundation 2 is 500 mm. The distance between the composite wall and the slope is greater than the length of the second column 4. The first column 3 and the second column 4 are connected into a whole by the cross beam 5. The distance between the first column 3 and the second column 4 is greater than the thickness of the composite wall 1. The height of the cross beam 5 is greater than the height of the composite wall 1. During use, the operating platform straddles the composite wall 1. The first column 3 is located inside the composite wall 1 and is placed on the raft foundation 2. The second column 4 is located outside the composite wall 1, with part placed on the raft foundation 2 and the other part cantilevered. A counterweight 6 is arranged on the first column 3. The operating platform can achieve a balanced effect completely relying on its own structure, ensuring the operation safety of construction workers on the construction platform.

[0029] The operating platform is prefabricated in the factory, is adapted to the composite wall 1, and can be used only after passing the inspection. It is hoisted to the target position for the splicing operation of the composite wall 1. The operating platform occupies a small area, reduces the influence of on-site conditions on the use of the operating platform, and increases the applicability of the operating platform. The traditional method using a scissor lift or an aerial work platform requires backfilling and hardening the side of the raft foundation before use. This method has safety risks of mechanical use caused by uneven settlement, and also causes ineffective connection between processes, increased construction period, and cost waste. The operating platform of the present application can effectively solve the above problems. By using a customized finished operating platform matching the composite wall, the safety risk of erection and dismantling is reduced, and the overall structure is safe and reliable.

[0030] Preferably, a construction platform 7 is arranged on the second column 4 for the outer joint operation of the composite wall; multiple construction platforms can also be arranged on the first column 3 for the inner operation of the composite wall.

In order to facilitate the operation platform to smoothly straddle the laminated wall during the hoisting process, limiting rollers 8 are provided on the inner sides of the first upright column 3 and the second upright column 4. The limiting rollers 8 face the laminated wall 1. During the lowering or taking-out process, the limiting rollers 8 can contact the laminated wall 1 and roll along the laminated wall 1, which is convenient for hoisting the operation platform. At the same time, it can also prevent the upright columns from hitting the laminated wall 1 and damaging the laminated wall 1.

[0032] Preferably, a rubber layer is provided on the outer side of the limiting roller 8, which plays a buffering role when the limiting roller 8 contacts the laminated wall 1, and at the same time can protect the laminated wall 1 from being impacted. At least two limiting rollers 8 are provided vertically on the first upright column 3 and the second upright column 4.

[0033] Optimized implementation manner. The distance between the limiting roller 8 of the first upright column 3 and the limiting roller 8 of the second upright column 4 is greater than the thickness of the laminated wall 1, which is convenient for the operation platform to have enough space for hoisting, while meeting the use requirements of the operation platform and reducing the requirements for hoisting accuracy.

[0034] Preferably, the protruding length of the limiting roller 8 on the second upright column 4 is less than the distance between the outer wall of the laminated wall 1 and the edge of the raft foundation 2, that is, the distance between the end of the limiting roller 8 far from the second upright column 4 and the side wall of the second upright column 4 facing the accommodating cavity is less than the distance between the outer wall of the laminated wall 1 and the edge of the raft foundation 2. During use, it can be ensured that at least part of the second upright column 4 is supported on the raft foundation 2.
