Description

Multipurpose pull-connecting piece without hole opening

Technical Field

The utility model relates to an engineering structure construction field particularly, relates to an exempt from trompil multipurpose and draw union piece.

Background

In recent years, with the increasing of building height and the rapid development of the building industry, the management concepts of lean construction and green construction are fully paid attention in the industry, and the construction process of aluminum mould and climbing frame with outstanding advantages is widely applied in the construction process of high-rise buildings. However, the popularization of the binding type also leads to the superposition of two process defects, and when the conditions that the appearance of the structure is not favorable for climbing, the height of the structure is not enough, the insertion time of each procedure is uncontrollable, the climbing cost exceeds the standard, the market supply of the climbing frame is insufficient and the like occur, the climbing frame process can not be implemented. The traditional process of the flatly-laid overhanging I-steel outer frame is inconsistent with the characteristic that the aluminum mould cannot be drilled on site, so that the aluminum mould construction process has to be abandoned, the application range of the aluminum mould is seriously influenced, and the popularization of the aluminum mould is very unfavorable.

In addition, the I-steel must pass the outer wall of building to the tradition tiled overhanging I-steel stretches into indoor laying on major structure floor, and 3U type built-in fittings anchor of reuse exist a great deal of quality safety hidden danger on floor board or structure roof beam: 1) the layout of the overhanging I-beam extending into the room is complex, and especially in the room at the corner, the I-beam is more densely arranged, which seriously hinders the carrying of the construction procedures such as the personnel passing of an overhanging layer, garbage cleaning, later-stage brickwork, decoration, installation and the like, and seriously affects the safe civilized construction and the construction period; 2) the hole reserved when the overhanging I-steel passes through the outer wall has leakage risk, the later-stage hole plugging and decoration surface layer repairing belongs to edge overhead operation, the workload is large, the operation is complex, the safety risk is very large, the integrity of the structure is damaged, and the quality hidden danger is caused; 3) according to the requirement that the length of the cantilever I-steel fixing section is not less than 1.25 times of the cantilever section, the shortest cantilever I-steel needs 3 meters, the corner needs 4 to 6 meters, even 9 meters, the steel input is large, the weight is large, a tower crane is needed in the whole process of installation and disassembly, blind areas are large in the lifting process, and great potential safety hazards exist.

At the moment, a pull rod type overhanging outer frame process is developed in the industry, the process principle is that embedded parts such as bolts are embedded in a structure, then overhanging I-shaped steel is connected with the bolts embedded in an outer wall, the method can achieve the effect that holes are not reserved in the outer wall, I-shaped steel can be saved, but a large number of small holes are required to be formed in a template to fix the embedded parts when the bolts are embedded, the method is mature in application of a project using a wood mold, but still cannot solve the problem that an aluminum mold is not suitable for forming holes, and therefore the project using the aluminum mold cannot be popularized.

An effective solution to the problems in the related art has not been proposed yet.
