Description

Technical Field

[0001] The invention relates to the technical field of house construction with a steel structure corridor, and in particular to a rear-mounted integral lifting and attachment device of a limited bearing capacity structure and a construction method thereof. Background Art

[0002] As modern urban construction continues to develop with the trend of the times, the functions of various commercial buildings and complexes are becoming more and more diversified, the structures are becoming more complex, and the design requirements of owners are becoming higher and higher. In order to achieve the integrity of the appearance of the complex building, more and more owners require the addition of steel structure corridors between buildings, so as to achieve an overall beautiful complex building. The construction of the steel structure corridor between towers, taking into account various factors, often uses a lifting platform for overall lifting construction. In order to ensure the stability of the lifting platform, the lifting platform often needs to be attached to the lifting structure of the main structure. The stability of the lifting structure determines the stability of the lifting platform, thereby ensuring the stability of the overall lifting construction of the steel structure corridor.

[0003] Because the design unit only meets the load of the steel corridor in the service stage when designing the steel structure corridor, and does not consider the transfer load during the lifting construction, which is different from the final use stage. The concrete structure of the steel structure corridor can provide structural anchoring, but its reinforcement ratio, stirrup ratio and force form often do not meet the post-anchoring requirements of the lifting structure. The concrete structure that can provide structural anchoring cannot meet the requirements of post-anchoring, and there are safety hazards when the steel structure corridor is lifted as a whole. The existing technology only considers that the design of the lifting platform meets the requirements of the overall hoisting of the steel corridor, and does not consider whether the bearing capacity of the lifting structure to which the lifting platform is attached can meet the requirements of the lifting platform and the measures taken if the requirements are not met. During the implementation of the overall lifting construction method of the steel structure corridor, the lifting force of the steel structure corridor is often finally transferred to the main structure through the lifting platform. For the original main structure, only the load of the steel structure corridor in the service stage was considered during the design, and the load transfer during the lifting construction process was not considered. The reinforcement ratio and force form of the post-anchoring concrete structure of the lifting platform of the steel structure corridor often do not meet the post-anchoring requirements of the lifting structure.

[0004] The above information disclosed in this Background section is only for enhancement of understanding of the background of the invention and therefore it may contain information that does not form the prior art that is already known to a person of ordinary skill in the art. Summary of the invention

[0005] The purpose of the present invention is to provide a post-installed integral lifting attachment device for a limited bearing capacity structure and a construction method thereof, which not only meets the requirements for the overall lifting of the steel corridor, but also makes the bearing capacity of the lifting structure to which the lifting platform is attached meet the requirements of the lifting platform, so that the reliability of the lifting structure can be ensured during the overall lifting construction of the steel structure corridor, thereby ensuring the safety of the steel structure corridor during the overall lifting process.

[0021] A guide frame is arranged at the front end of the horizontal suspension beam and is located between the hydraulic lifter and the roof section steel corridor to guide the steel strand.

[0022] In the rear-mounted integral lifting and attachment device for a limited bearing capacity structure, at least two first reinforcement rods are cross-fixed between the first building surface and the second building surface.

[0023] In a preferred embodiment of the post-installed integral lifting and attachment device for a limited bearing capacity structure, the first building surface and the second building surface are respectively embedded with steel plates, the first reinforcement rod connects the first building surface and the second building surface via the steel plates, and the second reinforcement rod connects the second building surface via the steel plates.

[0024] In the rear integral lifting and attachment device of a limited bearing capacity structure, the first building surface and the second building surface are respectively provided with drilling holes for implanting chemical reagents for fixing, and the chemical screw is connected to the drilling holes through gaskets and nuts to fix the steel plate embedding plate.

[0025] In the rear-mounted integral lifting and attachment device of the limited bearing capacity structure, the roof section steel corridor is a corridor truss structure.

[0026] In the post-installed integral lifting and attachment device of the limited bearing capacity structure, the through-wall screw is a tension screw that is pulled in the second building surface, and the tension screw is bolted via a gasket and a nut.

[0027] In the rear-mounted integral lifting and attachment device of a limited load-bearing capacity structure, a pair of parallel vertical stiffening plates are vertically fixed on the upper surface of the horizontal suspension beam, a pair of horizontal stiffening plates vertically connect the vertical stiffening plates and the upper surface, and a pair of parallel vertical stiffening plates and a pair of horizontal stiffening plates enclose the hydraulic lifter.

[0028] In the rear integral lifting and attachment device of the limited bearing capacity structure, the two inclined rods are arranged obliquely relative to the roof section steel corridor and the two inclined rods and the roof section steel corridor form a triangular structure, and the two inclined rods and the columns form a triangular structure.

[0029] In the rear-mounted integral lifting and attachment device for a limited bearing capacity structure, the first building surface is parallel to the second building surface, and the two second reinforcement rods are arranged in parallel.

[0030] The construction method of the rear integral lifting and attachment device using the limited bearing capacity structure comprises the following steps:

[0031] The first end of at least one first reinforcing rod is fixedly connected to the first building surface, the second end relative to the first end is fixedly connected to the second building surface, one end of at least one through-wall screw is connected to the second end of the first reinforcing rod, the third end of at least one second reinforcing rod is fixedly connected to the other end of the through-wall screw, the fourth end of the second reinforcing rod is fixedly connected to the roof section steel corridor, and the through-wall screw bears tensile stress;

A steel strand for lifting heavy objects passes through the middle of the hydraulic lifter. A guide is installed at the front end of the horizontal suspension beam and is located between the hydraulic lifter and the roof section steel corridor to guide the steel strand.

[0034] In the above technical scheme, the present invention provides a rear integral lifting and attachment device of a limited bearing capacity structure, which has the following beneficial effects: the device uses the roof section steel corridor as the basic structure of the lifting platform, has good stability, and is easy to dock after lifting. After docking, it is not necessary to dismantle the assembled end trusses, only some temporary reinforcement structures need to be dismantled, and both erection and dismantling are convenient. After the end trusses at both ends of the high-altitude corridor truss are used as the basic structure of the lifting platform, the middle part of the high-altitude corridor truss can be lifted as a whole through the lifting platform after the assembly on the ground is completed. The construction work is mainly concentrated on the ground, which can reduce the amount of high-altitude work to a minimum, has little impact on the construction of other specialties, and can be constructed in parallel on multiple work surfaces. In addition, the end trusses at both ends of the corridor truss are removed, and only the middle part of the high-altitude corridor truss needs to be lifted during the lifting process, which reduces the total lifting weight and reduces the difficulty of lifting, which is beneficial to construction. When dismantling the lifting platform, it is only necessary to dismantle the temporary facilities added to the end trusses, and retain the end trusses that have been erected, which reduces the workload of dismantling and is beneficial to construction cost control. The present invention fully anchors the lifting structure and its reinforcement rods to the main structure to ensure that the force of the lifting structure is within the load range that the main structure can bear, thereby ensuring the safety of the overall lifting of the steel structure corridor. When the present invention lifts a heavy steel corridor and the force of the lifting platform cannot be met, the reinforcement rods can be used to greatly increase the tensile strength of the lifting platform, thereby ensuring the stability and safety of the lifting platform, which not only meets the requirements for the overall hoisting of the ground section steel corridor, but also makes the bearing capacity of the lifting structure to which the lifting platform is attached meet the requirements of the lifting platform.
