Description

Technical Field

[0001] The utility model belongs to the technical field of the design of construction tools, and particularly relates to a vertical transportation auxiliary tool for a formwork support system in a confined space. Background Art

[0002] With the development of society and the continuous update of construction technology, the safety requirements for enclosed confined spaces are becoming increasingly strict. After the concrete structure in the confined space is poured, the vertical transportation of a large number of formwork support systems inside after demolition is rather difficult. The size of the manhole opening reserved at the top of the confined space is small, the cycle of manual material transfer is long, and the safety factor and construction efficiency are low; reserving a structural construction hole causes difficulties in subsequent construction, affects the structural safety in use, and increases the safety risk. In view of the above situation, the utility model designs a vertical transportation auxiliary tool for a formwork support system in a confined space, which greatly ensures the safety of personnel while improving the construction efficiency. Content of the Utility Model

[0003] Aiming at the deficiencies existing in the prior art, the utility model provides a vertical transportation auxiliary tool for a formwork support system in a confined space, which can utilize the permanent manhole reserved in the enclosed confined space for the vertical transportation of the formwork support system, maximize the construction efficiency, and reduce the safety risk of personnel.

[0004] The utility model realizes the above technical purpose through the following technical means.

[0005] A vertical transportation auxiliary tool for a formwork support system in a confined space includes a circular base. A plurality of vertical supports are vertically welded along the circumferential direction on the base to form a vertical support system. A plurality of circular hoops are welded inside the vertical support system. A galvanized steel plate is welded outside the vertical support system as an external enclosure structure, and the bottom of the galvanized steel plate is also welded and fixed to the base; lifting rings are symmetrically welded at the top of the galvanized steel plate, and traction lifting rings are also symmetrically welded on the base outside the galvanized steel plate.

[0006] Further, three circular hoops are welded inside the vertical support system.

[0007] Further, the thickness of the base is 25 mm and the diameter is 1000 m.

[0008] Further, the vertical supports are made of round steel with a diameter of 20 mm.

[0009] Further, the circular hoops are circular structures bent from round steel with a diameter of 20 mm.

[0010] Further, the thickness of the galvanized steel plate is 2 mm.

[0011] Further, the lifting rings are made of round steel with a diameter of 20 mm.

[0012] The utility model has the following beneficial effects:

[0013] The utility model can improve the construction efficiency for the vertical transportation of the formwork support system in a closed confined space, avoid manual material transfer, ensure the safety of personnel working in the confined space, and is simple in overall production, convenient and fast and flexible in use. The overall size and shape of the device match the permanent manhole reserved in the confined space, and the vertical transportation of the formwork support system can be carried out by using the permanent manhole reserved in the closed confined space, which maximally improves the construction efficiency and reduces the personnel safety risk.
