Embodiment Construction

[0049] The following is attached figure 1 To attach Figure 5 The present invention is further described in detail with specific examples.

[0050] Such as figure 1The shown pier maintenance device includes a frame, a track, a maintenance membrane assembly 4 and a lifting assembly 3 . The frame is fixed on the top of the pier column 5, the track is arranged on the frame along the circumference of the pier column 5, and the curing film assembly 4 includes a shaft 4.1 and a curing film roll 4.4 arranged on the shaft 4.1. The lifting assembly 3 in this embodiment adopts a pulley block structure, which includes a wheel block body 3.6, a traction member and a lifting member. The traction piece is connected with the wheel set fuselage 3.6, and the traction piece cooperates with the track for the traction wheel set fuselage 3.6 to rotate around the pier column 5 along the track. The lifting piece is connected with the wheel set body 3.6, and the lifting piece is connected with th...

Abstract

The invention relates to the field of buildings, and provides a pier column maintenance device and a film covering construction method. The pier column maintenance device comprises a rack fixed to a top of apier column, a lifting assembly slidably arranged on the rack in the circumferential direction of the pier column, and a maintenance film assembly which comprises a shaft rod and a maintenance film roll rotatably arranged on the shaft rod, wherein the shaft rod is connected with the lifting assembly; and the lifting assembly can lift or lower the maintenance film roll while sliding in the circumferential direction of the pier column so that the maintenance film roll can be wound around the pier column according to the spiral track. After the rack is hoisted at the top end of the pier column, a constructor can make the maintenance film spirally wind on the pier column on the ground through the lifting assembly, and therefore in the pier column maintenance film covering construction process, a crane does not need to be matched for construction, a support does not need to be erected, the construction period can be shortened, the construction cost can be reduced, high-altitude film covering operation of workers is avoided, and potential safety hazards of construction are eliminated.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a pier maintenance device and a film-covering construction method. Background technique [0002] After the concrete pouring of the bridge pier column is completed, and the strength of the concrete reaches the strength of the formwork removal, the concrete must be maintained in time after the formwork is removed. Otherwise, the water in the concrete will evaporate, and the strength of the pier column concrete will be affected, and shrinkage cracks will easily appear, seriously affecting the pier column. quality and durability. The shrinkage cracks on the surface of the pier column will cause water and oxygen in the air to enter the interior, causing the steel bar of the pier column to corrode, and further development will cause the protective layer of the pier column concrete to peel off, reducing the bearing capacity of the pier column. [0003] The maintenance of ...
