Supporting wall fixing device of high-rising building construction pedestrian safe ladder stand and construction method

Abstract

The invention provides a supporting wall fixing device of a high-rising building construction pedestrian safe ladder stand. The supporting wall fixing device comprises a pre-embedded part suit assembly, a dismantling tool, a supporting wall exterior connecting part and a building steel pipe support. The supporting wall fixing device is characterized in that the pre-embedded part suit assembly comprises a taper nut and a pulling resistant rod part, wherein the taper nut and the pulling resistant rod part are mutually connected; the taper nut is externally provided with a corrugated cover, and the dismantling tool comprises a taper nut dismantling tool for dismantling the taper nut and a corrugated cover dismantling tool for dismantling the corrugated cover; and the exterior connecting part comprises a lead screw, a nut sleeve pipe and a fixing fixture, and the building steel pipe support comprises a building steel pipe and a plurality of building fastening parts. According to the supporting wall fixing device of the high-rising building construction pedestrian safe ladder stand and a construction method, the defects of low construction efficiency, material wasting, high-rising building appearance sense quality affecting and the like existing in the connection of the pedestrian safe ladder stand and the bare concrete high-rising building in the prior art are avoided, the construction efficiency is high, the adhesive force is high, repaired wound surface is small, and repeated using can be achieved.

Description

technical field [0001] The invention relates to the technical field of high-rise structure construction, in particular to a fixing device and a construction method for a pedestrian climbing ladder buttress wall during the construction of high-rise structures. Background technique [0002] At present, the construction of high-rise structures requires the construction of pedestrian safety ladders for construction workers to go up and down. In the traditional technology, the connection and fixation of pedestrian safety ladders and high-rise structures is mostly to install embedded parts on high-rise structures, and weld the connecting rods and embedded parts. The method of stabilizing the ladder, or using the formwork of the towering structure to pull the steel bars to weld the connecting rods to fix the ladder, has the following disadvantages in actual construction: [0003] (1) The method of welding connecting rods with embedded parts is adopted, and a large number of embedde...

AI Technical Summary

Problems solved by technology

[0004] (2) Adopting the method of post-drilling to install embedded parts and welding connecting rods, the drilling will damage the concrete surface, and it is easy to collide with the main reinforcement, which brings inconvenience to drilling

The embedded parts are installed after drilling. The embedded parts are buried in a shallow depth, with low wind resistance and potential safety hazards.

[0005] (3) A pre-embedded point is connected to a connecting rod. If you want to increase stability, you need to add embedded points, which will cause more repairs on the concrete surface of towering structures, especially fair-faced concrete that does not require post-decoration, which will reduce The pass rate of a construction

[0006] (4) The embedded parts that need to be removed are difficult to remove during the demolition process, and it is easy to cause major damage to the concrete at the embedded parts, increasing the repair surface

New and old structures are prone to shrinkage joints, obvious repair defects, and poor appearance
