Formwork mounting and support reinforcing system for collector well, elevator shaft and the like

Abstract

The invention discloses a formwork mounting and support reinforcing system for a collector well, an elevator shaft and the like. At first, rebars is fixed on a rebar skeleton according to the planar location size and depth of a well while the thickness of a rebar protection layer is controlled; a bottom formwork and a side formwork are erected on the protection layer rebars, and vent holes are formed in the longitudinal and transverse directions of the bottom formwork at an interval of 1.5m; after that, a horizontal square timber is laid on the bottom formwork, and a vertical square timber is erected beside the side formwork and serves as a back arris; an upright rod is matched with a longitudinal horizontal rod and a traverse horizontal rod and firmly fixes the bottom formwork and the side formwork; transverse horizontal rods on the uppermost layer protrude out of the formwork edges on the two sides by 300mm; finally, the formworks in heaps are flatwise placed on the transverse horizontal rods, and the number of the formworks is calculated. Therefore, the well position shift can be avoided while stable support can be guaranteed effectively, and the cost and unnecessary repair can be effectively reduced. The system is mainly suitable for mounting and support reinforcing of various deep well formworks, lower than a base plane, of collector wells and elevator shafts in a basement raft foundation.

Description

technical field [0001] The invention relates to a formwork installation, support and reinforcement system for water collection wells, elevator shafts and the like. Background technique [0002] When designing basement foundation rafts with water collection wells and elevator shafts, it will be very troublesome to fix the formwork support, and the stability is relatively poor, and it is difficult to level the bottom of the well to the design elevation when pouring concrete. If the formwork support is not firmly reinforced, It will cause the concrete expansion of the water collection well and the elevator shaft, and the steel protection layer is not enough. In serious cases, it will cause the displacement of the well, and the plane size and depth of the well will not meet the design requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art, and provide a formwork installation and s...

[0002] When designing basement foundation rafts with water collection wells and elevator shafts, it will be very troublesome to fix the formwork support, and the stability is relatively poor, and it is difficult to level the bottom of the well to the design elevation when pouring concrete. If the formwork support is not firmly reinforced, It will cause the concrete mold expansion of the water collection well and the elevator shaft, and the steel protection layer is not enough. Seriously, it will cause the displacement of the well, and the plane size and depth of the well will not meet the design requirements.
