Description
Technical Field
The invention belongs to the field of building construction, and particularly relates to a tie system for a suspended scaffold.
Background
The overhanging scaffold is a simple facility used in a building, the erection method is to divide the scaffold with the full height into a plurality of sections, the erection height of each section is not more than 20m, the overhanging beam or the overhanging frame is used as the scaffold foundation to perform subsection overhanging and subsection erection of the scaffold, the scaffold with the height of more than 50m can be erected by the method, and the outer vertical surface of the overhanging scaffold needs to be fully provided with a cross brace.
Common traditional scaffold frame method of encorbelmenting is to encorbelment the section of encorbelmenting of girder steel tiling anchor in floor face, and the section of encorbelmenting is overhanging the pole setting basis of setting up as the scaffold frame outward, and anchor section length is not less than 1.25 times of the section of encorbelmenting. The whole frame body is only considered to be cantilevered by the cantilever steel beam from the beginning to the completion of the mission. For safety, the specification stipulates that a steel wire rope or a steel pull rod is tensioned at the outer end part of the overhanging section of each beam and is obliquely tied with the upper layer of building structure, but the steel wire rope and the steel pull rod are only used as safety reserves and do not participate in stress calculation of the overhanging steel beam. When the special part is overhung in an overlong way, an oblique section steel is obliquely supported on the outer side beam of the next layer of structure below the outer end part of the overhanging section.
However, along with the rise of assembly type structure, can appear a lot of inadaptations when using the scaffold frame of encorbelmenting of traditional formula, therefore appear a neotype pull rod and hang the scaffold frame, this kind of general thinking of hanging the scaffold frame is exactly to trompil behind the one end welded connection end plate of girder steel and on structure boundary beam or wall post with high strength bolt anchor, hang a reinforcing bar pull rod with the other end of girder steel and hang on the boundary beam or the wall post of previous layer structure. However, the specific common practice of the method has many problems, such as: after a single bent steel plate is welded at the upper end of a steel pull rod, the steel pull rod is hung outside an edge beam of an upper-layer structure by using a bolt, so that the bending angle of the steel plate is often inconsistent with the tying angle of a steel pull rod, and therefore, a steel wire rope or the steel pull rod can be influenced by an oblique steel plate and cannot completely tighten a cantilever beam, and the steel wire rope or the steel pull rod cannot be effectively stressed, and great potential safety hazards exist; the steel bar pull rod conflicts with the position of the upright rods at the inner row of the scaffold, so that the steel bar pull rod is installed in an offset way and is not positioned on the same axis with the steel beam, the steel beam generates secondary bending moment due to the fact that the outer side of a plane is pulled outwards, meanwhile, the stress of a bolt connecting joint of the inner end of the steel beam and a structural boundary beam is complicated and more unfavorable, and great potential safety hazards exist; the lengths of the steel bar pull rods of different parts of the same building are different, the lengths of the pull rods of different buildings are different, and in a common method, each position is independently processed and manufactured according to the actual length required on site, so that the universal turnover cannot be realized, the system is seriously uneconomical, and much cost is increased for purchasing and keeping.
