Description

Technical Field

[0001] The present application relates to the technical field of building construction, and more specifically, to a large-span beam installation auxiliary device. Background Art

[0002] In the airport construction of the existing technology, the main structure is mostly large space and large span, the frame column spacing is large, generally reaching 12 meters to 18 meters, and there is no horizontal floor in the height direction. The conventional curtain wall form is a vertical column as the main load-bearing curtain wall structure, which needs to be fixed on the horizontal floor. In the airport's large space and large span main structure, only the frame column is used as the support of the curtain wall. A new curtain wall structure system with horizontal large span beams as the main force and combined with vertical hangers came into being. The large span beams are used as the main load-bearing components to bear horizontal loads, and the dead weight is borne by slender hangers, which solves the problem that the airport's main structure has no horizontal floor as the support of the curtain wall columns.

[0003] As the main load-bearing member bearing horizontal loads, the cross-section of the large-span beam is generally large. When aluminum profiles are used as the beam, the weight is about 200kg to 400kg, and when T-steel is used as the beam, the weight is about 500 to 1300kg. The length of the beam is about 6 meters to 12 meters. For the hoisting of this beam, the solution adopted in the prior art is to use at least one automobile crane, one mobile hanging basket and one indoor and outdoor straight-arm aerial work platform to hoist the beam to a certain height. The workers in the hanging basket manually pull the beam to the curtain wall surface, and the workers on the indoor and outdoor aerial work platforms install the beam connectors. After completing these steps, the installation of the beam is completed. Such construction hoisting has great risks, low construction efficiency and is prone to safety accidents. When the ground is uneven or the large beam is pulled, the crane may roll over and have poor stability. At the same time, such a lifting scheme consumes a lot of manpower, and lacks monitoring of horizontal and vertical installation accuracy. It is greatly affected by the level of manual operation, which in turn affects the overall quality of the project and increases costs. In addition, weather factors have a huge impact on lifting work, especially in thunderstorms or strong winds, which make normal construction impossible. Utility Model Content

[0060] 5. The gear drive mechanism drives the gear 3 to operate, and the lifting support structure is lifted up with the large-span beam 6. When the horizontal laser instrument 9 on the side of the two beam support arms emits laser, the laser receiver 10 does not receive the laser and issues an alarm.

If the laser receiver 10 does not receive the laser before reaching the scheduled installation position, the alarm continues.

[0065] 10. Push the long-span beam 6 to the expected installation position and connect it with the installed beam 21 (i.e., the beam installed on the structural column 17).
