Description

TECHNICAL FIELD

[0001] The utility model relates to a hoisting construction platform, in particular to a platform for realizing the three-dimensional hoisting construction of the upper large (heavy) steel structure of the floor by relying on the trestle formed by the basement roof. BACKGROUND

[0002] In the field of steel structure construction engineering, there is a situation that the basement has a length-width ratio close to 1:1.5 and cannot use hoisting machinery outside the basement building for steel structure hoisting construction, and the basement roof cannot meet the self load and operation load of large machinery due to insufficient bearing capacity, resulting in inability to directly perform roof operation.

[0003] In the prior art, similar industrial projects generally use traditional tower cranes or basement back roof hoisting.

[0004] Tower crane hoisting generally uses single or multiple tower cranes for steel structure hoisting operation. This method can only perform horizontal step-by-step hoisting, which is slow and cannot hoist overweight steel components or heavy equipment. The tower crane needs to be set up at the basement structure raft, the tower body penetrates the basement structure roof, the roof forms a construction hole, and there is a risk of leakage in the later repair. The tower crane itself is also difficult to remove inside the factory building. There is a lot of cross construction with other hoisting operations, which greatly reduces the construction efficiency.

[0005] The basement back roof method refers to that after the completion of the basement structure, large hoisting equipment needs to travel to the structure roof for steel structure hoisting. In order to meet the demand of the structure roof bearing large hoisting equipment load, support frames (48 disc buckles) or DN200 steel pipe columns are used to back support the basement structure beam plate under the hoisting equipment walking route. The back support frame or steel pipe column forms a partition "wall" to the floor space, which divides the space into several fragmented blocks longitudinally. The basement space cannot be effectively horizontally isolated from the upper hoisting, and the secondary structure operation of the basement cannot be inserted into the construction, which greatly affects the project period. At the same time, the structure roof needs to be protected by heavy finished products, which is high in cost and not conducive to cost saving.

[0006] With the development of the process needs, the high-end electronics, pharmaceutical and other plant energy saving and height limit increasingly detailed, need to set the full basement, to meet the energy saving and height limit appeal. Its upper part or steel structure or there are large equipment. In the installation needs to use large lifting equipment, while the basement close to 1:1.5 (1 for the upper building) length-width ratio, or the upper building plane length-width geometry > 30m, can not be used in the basement roof or the proposed hoisting building outside the conventional large hoisting machinery (need to select a large hoisting equipment, hoisting cost multiplied), steel structure hoisting construction, these equipment must travel to the basement roof operation, in order to meet the operation requirements. The basement structure design will only consider the use of load, not to consider such temporary and overweight construction load, so the general case of the basement roof bearing capacity can not meet the operation load demand of large hoisting machinery, the traditional operation by not removing the basement scaffold to improve the hoisting required basement roof bearing capacity, but in the case of multi-storey basement, the lower part of the scaffold body can not be removed, thus causing the overall measure cost greatly increased.

[0007] Specifically, the prior art traditional installation construction method has the following disadvantages:

[0008] (1) many safety hazards, because it needs to rely on tower group hoisting, tower crane operation radius overlap each other, and placed in the basement structure, cross operation safety hazards, easy to collide;

[0009] (2) long construction period, can not quickly roof sealing, in the face of the rainy season in the north and south of the leakage plight;

[0010] (3) due to the cross operation with other civil engineering, will greatly reduce the overall construction efficiency of the site;

[0011] (4) hoisting large components need to use large hoisting equipment for special hoisting, high cost;

[0012] (5) tower crane lifting capacity is limited, it is difficult to meet the steel column, truss, equipment and other heavy lifting;

[0013] (6) the traditional operation by not removing the basement scaffold to improve the hoisting required basement roof bearing capacity, but in the case of multi-storey basement, the lower part of the scaffold body can not be removed, thus causing the overall measure cost greatly increased.

[0014] In summary, the prior art hoisting method has the problems of slow construction progress, low work efficiency and so on. Only one-way (one layer by layer hoisting) hoisting, can not realize horizontal and vertical two-way three-dimensional hoisting. Practical new type content

[0015] The utility model provides a trestle platform for hoisting construction based on basement roof, which aims to overcome the above-mentioned deficiencies of the prior art and realize hoisting walking operation on the basement roof.

[0016] The technical solution of the utility model: a trestle platform for hoisting construction based on basement roof, which comprises a column, a main beam, a secondary beam and a steel roadbed plate.

The end portions of adjacent main beams on the same straight line are supported on the support plates on both sides of the column. A plurality of mutually parallel and spaced steel roadbed plates are vertically laid on the secondary beams. The steel roadbed plates are mutually parallel to the main beams. The column is a vertical force-bearing member. The secondary beam provides stability for the main beam. The load of the main beam is transmitted to the column through the support plates. The steel roadbed plates are arranged on the secondary beams to form a trestle platform for walking cranes and providing a standing space for a car crane or a truck. The platform can prevent damage to the basement roof.

[0017] Preferably, the column is a steel column, and the support plates are welded to the column.

[0018] Alternatively, preferably, the column is a concrete column, and a part of the support plates is pre-buried in the column.
