A technology for hoisting locks and quick installation of cross braces for wharf concrete cross braces

Abstract

The invention discloses a hoisting lock for a wharf concrete cross-brace and a method for quickly mounting the cross-brace. The hoisting lock comprises two pieces of channel steel, a fastening hoisting ring and a fastening bolt. The method for quickly mounting the cross-brace comprises the following specific steps of: clamping a count-weight concrete cross-brace and a to-be-mounted concrete cross-brace in positions by utilizing the hoisting lock, and strengthening the fastening bolt in position to wait for hoisting; guiding the cross-brace to mount in position step by step through manual work and machinery; after the cross-brace is mounted in position, preliminarily fixing the cross-brace; hooking and hoisting the middle part of the count-weight concrete cross-brace by an auto crane in an auxiliary mode, and completing finished product protective measures; dismounting the lock; and timely connecting after the lock is dismounted, and pouring concrete, thereby preventing a reinforcing steel bar from corrosion. The hoisting lock disclosed by the invention is simple to manufacture and is reasonable in structure; construction of the hoisting method saves labor cost, time cost and mechanical cost; hoisting mounting efficiency is improved; and staff does not need to enter a position below the upper structure, and construction is carried out outside a front line, so that visual field and ventilation performance are free of problems, and safety is higher.

Description

technical field [0001] The invention relates to the field of horizontal brace installation for hydraulic wharves, in particular to a wharf concrete horizontal brace hoisting lockset and a process for fast installation of the horizontal brace. Background technique [0002] The installation of hydraulic wharf cross braces is limited by tides and construction techniques. Installation and construction can only be carried out after the construction of the upper structure is basically completed. Moreover, the traditional construction method can only be completed with the cooperation of excavators and cranes, which is time-consuming and laborious and easy to install. The completed concrete components are bumped, the finished product is poorly protected, the construction efficiency is low, and the safety hazard is great. Moreover, the installation of the cross brace is affected by the outstretched ribs, resulting in serious deformation of the steel bars, making it difficult to strai...

Problems solved by technology

[0002] The installation of horizontal braces of hydraulic wharves is limited by tides and construction techniques. Installation and construction can only be carried out after the construction of the superstructure is basically completed. Moreover, the traditional construction method can only be completed with the cooperation of excavators and cranes, which is time-consuming and labor-intensive and easy to install. The completed concrete components are bumped, the protection of the finished product is poor, the construction efficiency is low, and the safety hazard is great

Moreover, the installation of the cross brace is affected by the extension ribs, resulting in serious deformation of the reinforcement bars, making it difficult to straighten

[0003] The horizontal bracing elevation is low and affected by the tide during installation, and the superstructure or pier has been constructed during installation, and the distance from the superstructure is short; and the outer edge of the front line of the wharf should be extended to be flush with the front line, and the installation efficiency is low ( Under normal circumstances, only 2 to 4 can be installed for each tide), and additional personnel and sampans must be added. The personnel are working under the structural section covering the beam and slab, and the lack of oxygen and safety conditions are poor.
