Problems solved by technology

[0004] However, with the rise of prefabricated buildings, there will be many discomforts when using traditional cantilevered scaffolding, so a new type of suspension scaffolding with pull-up rods has emerged. The general idea of ​​this suspension scaffolding is to weld one end of the steel beam. Open a hole behind the end plate and use high-strength bolts to anchor it on the structural side beam or wall column, hang the other end of the steel beam on a steel bar to hang on the side beam or wall column of the upper structure
However, there are indeed many problems in its specific common practice. For example, the upper end of the steel tie rod is welded with a single piece of bent steel plate and then hung on the outside of the side beam of the superstructure with bolts. The knot angles are inconsistent, which will cause the steel wire rope or steel tie rod to be affected by the inclined steel plate and cannot fully tension the cantilever beam, resulting in the inability to effectively bear force and pose a great safety hazard; the position of the steel tie rod conflicts with the inner row of the scaffold, so Installing the steel tie rods off-center and not on the same axis as the steel beams will cause the steel beams to be pulled laterally on the plane and generate secondary bending moments. At the same time, the stress on the bolted joints between the inner ends of the steel beams and the structural edge beams will be more unfavorable. Great potential safety hazard; the lengths of steel tie rods in different parts of the same building are different, and the lengths of tie rods in different buildings are even more different. In common practice, each position is processed separately according to the actual length required on site. Unable to achieve universal turnover, so it is seriously uneconomical, and also adds a lot of cost to procurement and storage

Abstract

The invention discloses a tie system of an assembly type suspension scaffold. The tie system comprises a plurality of cantilever beams and the scaffold erected on the cantilever beams, and each cantilever beam is obliquely provided with a steel bar pull rod for tying the outer end of the cantilever beam with an upper-layer building structural beam; and the upper ends of the steel bar pull rods areconnected with the upper-layer building structural beams through upper connecting assemblies, the lower ends of the steel bar pull rods are connected with the cantilever beams through lower connecting assemblies, and turnbuckles are arranged on the steel bar pull rods. According to the tie system of the assembly type suspension scaffold, the steel bar pull rods are arranged on the cantilever beams to be tied to the upper-layer building structural beams, and it is guaranteed that the cantilever beams are stably connected.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a tie system for hanging scaffolding. Background technique [0002] Cantilevered scaffolding is a simple facility used in construction. The erection method is to divide the full-height scaffolding into several sections. Scaffolding can be erected by using this method. Scaffolding over 50m can be erected, and the facade of the cantilevered scaffolding must be fully equipped with scissors. [0003] The common traditional method of cantilevered scaffolding is to tile the cantilevered section of the cantilevered steel beam and anchor it on the floor surface, and the cantilevered section is extended as the pole foundation for scaffolding. The length of the anchored section is not less than 1.25 times that of the cantilevered section. The whole process from the beginning of erection to the completion of the mission only considers the force of the cantilevered steel bea...
