Description

Technical Field

[0001] The utility model relates to the field of construction technology, and particularly relates to a structure of an internal attached guide rail support for hoisting a multi-cavity steel pipe core column steel reinforcement cage. Background Art

[0002] With the continuous development of the construction industry, many super high-rise commercial complexes and office buildings have emerged. To meet the needs of different novel building forms and various large-span spaces, many complex structural forms have emerged. Due to its superior mechanical properties and seismic performance, multi-cavity steel pipes are widely used in modern buildings. The narrow and confined space inside the multi-cavity steel pipe column has a great impact on the construction of the multi-cavity giant column core column. Construction workers cannot carry out binding and welding operations in the narrow space, and the traditional construction method of directly hoisting the prefabricated steel reinforcement cage cannot ensure that the verticality and horizontality of the steel reinforcement cage meet the design requirements after installation, affecting the construction quality. At the same time, the construction safety problems caused by the over-length and overweight of the steel reinforcement cage during the construction process cannot be ignored. Content of the Utility Model

[0003] Aiming at the deficiencies in the prior art, the purpose of the utility model is to provide a structure of an internal attached guide rail support for hoisting a multi-cavity steel pipe core column steel reinforcement cage, strictly controlling the falling route of the steel reinforcement cage during the hoisting process, ensuring that the verticality and horizontality of the steel reinforcement cage meet the design requirements after installation, and realizing the quality control of the core column construction. At the same time, since the steel reinforcement cage is restricted during the hoisting process, it avoids the risk of personnel injury caused by the shaking of the steel reinforcement cage due to the action of wind or the like.

[0004] To achieve the above purpose, the utility model is realized through the following technical solutions: A structure of an internal attached guide rail support for hoisting a multi-cavity steel pipe core column steel reinforcement cage, including a main structure. At the top of the main structure, there is a bent steel bar, and the bent steel bar forms a buckle between the grouting hole, the ventilation hole and the diaphragm. At the elbow on one side of the ventilation hole, a 12mm steel bar sleeve is connected. At the bottom of the main structure, there are reserved steel bar heads for multi-cavity column pouring. The bent steel bar is bent into the grouting hole and connected to the guide rail through the sleeve. The guide rail is vertically arranged downward along the grouting hole, and the bottom of the guide rail is tied and fixed to the reserved steel bar head.

[0005] Preferably, both the bent steel bar and the guide rail are made of HRB300 steel bars with a diameter of 12mm.

[0006] Advantages of the Utility Model

[0007] 1. The utility model is applicable to the construction of super-long multi-cavity steel pipe column stiffening structures in high-rise buildings, large-span structures and bridge projects. The slide rail system can ensure the verticality and position accuracy of the steel reinforcement cage, reducing the errors that occur in the traditional method.

[0008] 2. The structural design of the present utility model is reasonable, avoiding problems such as insufficient hoisting accuracy and potential safety hazards during construction in the hoisting process of the traditional multi-chamber core column steel reinforcement cage. Through the guide rail, the steel reinforcement cage can enter the multi-chamber column cavity straight, ensuring that the verticality and horizontality of the steel reinforcement cage construction meet the design requirements; at the same time, the present utility model avoids the safety problems caused by the shaking of the steel reinforcement cage during hoisting. This method has significant advantages, reduces the construction difficulty and improves the construction efficiency, and has good reference and promotion effects on the hoisting construction of similar multi-chamber core column steel reinforcement cages.

[0013] Refer to Figure 1-2 , the following technical solutions are adopted in this specific embodiment: a structure of an internal attached guide rail support suitable for hoisting a multi-chamber steel pipe core column steel reinforcement cage, including a main structure. At the top of the main structure, there is a bent steel bar 1, and the bent steel bar 1 forms a buckle between the grouting hole 2, the ventilation hole 3 and the diaphragm 4. At the elbow on one side of the ventilation hole 3, a 12 mm steel bar sleeve 5 is connected to ensure the stability of the upper part of the guide rail. At the lower part of the construction measure, when the concrete pouring of the previous multi-chamber column is about to end, a steel bar head 6 is reserved at the top of the grouting hole of the previous multi-chamber column 8 and protected well. The guide rail 7 is connected to the upper sleeve and vertically downward along the grouting hole of the multi-chamber column, and is tied and lapped with the reserved steel bar head to ensure the stability of the lower part during the hoisting process.

[0014] This specific embodiment is a construction measure of an internal attached guide rail support suitable for hoisting a multi-chamber steel pipe core column steel reinforcement cage. The implementation is simple. Through the guide rail, the steel reinforcement cage can enter the multi-chamber column cavity straight, ensuring that the verticality and horizontality of the steel reinforcement cage construction meet the design requirements. At the same time, it provides more convenient construction conditions for on-site construction, has high application value and broad social benefits.

[0015] At the same time, the materials used in this specific embodiment are common, and after the implementation of this construction method, the structural deviation during construction is avoided, and there is no need to consider a special deviation correction plan, greatly reducing the labor cost and having high economic benefits.
