Description

Temporary fixation draws bearing structure to one side

Technical Field

The utility model relates to the technical field of building construction, in particular to a temporarily fixed cable-stayed support structure.

Background

The assembly type construction is a development trend of building engineering, is popularized all over the country at present, the prefabrication rate of some places is up to more than 40%, the assembly rate of the outer wall is up to more than 70%, and the main structural forms of the outer wall comprise a PC shear wall, a PC partition wall, a PCF wall, an exterior cladding and the like.

The prefabricated building has the advantages of high construction speed, short construction period, labor saving, energy saving, environmental protection and the like, simultaneously puts higher requirements on the scaffold of the outer wall, and has the advantages of convenient installation, high speed, labor saving, material saving, structural damage caused by the fact that the outer wall cannot be re-holed and the like on the premise of ensuring safety and reliability.

The existing common external wall scaffolds have three main types: the traditional steel pipe scaffold, the disc buckle type steel pipe scaffold and the assembled building externally-hung protection frame with the tripod have the defects that the traditional steel pipe scaffold needs a large amount of steel, consumes a large amount of labor, has large potential safety hazard, is poor in fireproof performance, is high in construction cost and the like, are suitable for traditional building engineering but cannot meet the construction requirement of an assembled building, and a prefabricated outer wall of the assembled building cannot be re-holed and cannot effectively reserve a tie point; although the disc-buckled steel pipe scaffold is good in safety and fireproof performance, the demand of steel and manpower is very large, the construction cost is 2 times higher than that of the traditional scaffold, and holes need to be newly formed in the outer wall and connection points need to be pre-buried in the same way as the traditional scaffold, so that the disc-buckled steel pipe scaffold is suitable for the construction of the traditional building project and cannot meet the requirement of assembly type construction; although the assembly type building external hanging type protective frame with the tripod saves a large amount of steel and has less labor consumption, the assembly type building external hanging type protective frame is only suitable for a stress point on a construction layer, and has a PC external shear wall structure with higher strength; the PC external partition wall, the PCF, the external hanging plate and other external wall systems which are weak in self stress cannot be used, the requirement on installation personnel is very high, and great potential safety hazards exist; in addition, the wall connecting bolt of the tripod is positioned below the operation platform, so that when the next hanging rack is dismounted, a person does not have a standing point and has no safety measures, and can only eject the bolt indoors and outdoors, and if the bolt cannot be ejected under special conditions, the potential safety hazard that a worker may fall off exists; therefore, the three scaffolds can not meet the requirements of the fabricated building, most of the existing scaffolds are directly fixedly installed on the wall of the fabricated building through bolts, the whole dismounting and installing process is complex, the labor intensity of constructors is improved by adopting the installation mode, the construction efficiency of the fabricated building is also reduced, and great inconvenience is brought to the construction work of the fabricated building.

The applicant has proposed a double-layer protection frame with a novel structure, which mainly comprises an operation platform which is arranged at the outer side of an assembly type building wall body needing construction and distributed along the extension direction of the assembly type building wall body needing construction; the operation platform comprises a plurality of double-layer protection frames which are assembled together in parallel, at least one pedal structure used for constructors to walk is arranged on each double-layer protection frame along the height direction of the double-layer protection frame at intervals, the middle lower part of each double-layer protection frame is arranged on the outer side of the lower-layer wall of the prefabricated building needing to be constructed through the ox foot structure, and the top of each double-layer protection frame is hooked on the outer side of the wall of the prefabricated building needing to be constructed through the top fixing device. By adopting the structure, the integral supporting strength and the safety performance are effectively improved, the transportation and storage cost is greatly reduced, the personal safety of assembly type building constructors is ensured, and great convenience is brought to the assembly type building construction work.

The top fixing device in the structure comprises a high-strength bolt and a U-shaped hook plate, wherein the high-strength bolt is used for being fixed on an outer wall, the U-shaped hook plate is used for hooking the U-shaped hook plate arranged on a top cross beam of the double-layer protection frame, a connecting plate is arranged at the upper end of the U-shaped hook plate, a connecting through hole matched with the high-strength bolt is formed in the connecting plate, the outer end of the high-strength bolt penetrates through the connecting through hole, and the high-strength bolt is matched with a connecting nut to be fixedly installed on the outer end of the high-strength bolt.

By adopting the top fixing structure, the problem that most of the upper end of the existing scaffold is free and fixed without a fixing device after the scaffold is fixed is solved, the problem of shaking in the construction process is avoided, and potential safety hazards are reduced to a certain extent. However, in practical application, it is found that in many cases, when an external wall scaffold is built, a building is not capped, the top end of the external wall of the top layer part is not fixed and restrained by a cross beam or other top structures, the horizontal load bearing capacity of the top layer part is far lower than that of a normal building external wall, and when the scaffold is fixed on the top layer external wall through the top fixing device, the external wall structure can be damaged, and personal injuries and deaths of constructors can be caused.

Therefore, there is a need to improve the existing top fixing structure of the shelter to solve the above problems.
