Embodiment Construction

[0040] Examples of the present invention are Figure 1-9 As shown, the specific implementation is described in further detail.

[0041] Such as Figure 1-9 The offset lifting and sliding method shown is one of the examples of the present invention. The structural elevation of the highest point of the roof (excluding the skylight) is 35.5m, and the structural elevation of the lowest point is 30.5m. The station building is a reinforced concrete frame-prestressed steel truss roof structure system, supported by reinforced concrete columns and steel columns, and is composed of 14 transverse trusses and 4 longitudinal trusses. The size of the roof structure is 165m×92m, and its projected area is about 15180m 2, the main height of the truss is 4m, and the cantilever structure is composed of secondary trusses and sealed steel beams around the roof, and the maximum length of the cantilever reaches 12m.

Abstract

The invention belongs to the field of steel structure construction, and particularly relates to an offset lifting slip device and method. A lifting supporting frame is arranged on a structure main body steel column; an assembled jig frame is erected on a floor, and main body roof trusses are assembled into an overall structure; the overall roof trusses are lifted to be arranged below a load-bearing track beam; hydraulic jacking and pushing driving equipment is connected with a lifting load-bearing beam through a pin shaft, the hydraulic jacking and pushing driving equipment is started, and thelifting load-bearing beam is jacked and pushed to slip to a calculated elevation on the load-bearing track beam; and four jacks are used on the structure main body steel column for jacking lower chords of the roof trusses, a lifter equipment device is shut down, all the jacks unload the main body roof trusses in place in synchronous and in-step modes, and the main body roof trusses and the structure main body steel column are fixedly connected, so that construction is completed. According to the offset lifting slip device and method, working at heights is reduced, safety is improved, the efficiency is high, and the cost of measures is saved.

Description

technical field [0001] The invention belongs to the field of steel structure buildings, and in particular relates to an offset lifting and sliding device and method. Background technique [0002] At present, steel structure roof systems are commonly used in large space structure buildings such as gymnasiums, opera houses, and museums. They have the characteristics of large area, large span, and complex construction conditions. The upper steel structure roof is usually installed by lifting and sliding. The lifting method can fully expand the construction of the working surface and select small hoisting machinery, which has the characteristics of high safety, high precision and good economy. The sliding method can work in parallel with other civil works, shortening the total construction period. The assembly platform is set outside the building, and the construction is relatively concentrated. The lifting equipment cannot enter the construction due to the narrow site or the ne...
