Embodiment 1

[0031] Combine below figure 1 with figure 2 The composition of the self-climbing monolithic tube frame system of the present invention is described in detail.

[0032] Such as figure 1 with figure 2 As shown, this embodiment discloses a self-climbing monolithic tube frame system over concrete volley beams, including a tube frame (not shown), a large formwork 2, a wall attachment device 3, a climbing shoe 4, a guide rail 5, and a hydraulic system 6. The tube frame includes a load-bearing frame body 7, a lower pylon body 8 and a lifting steel beam (not shown). The large formwork 2 is fixed on both sides of the elevator shaft shear wall 1 by means of tension bolts and installation positioning channel steel. The hydraulic system 6 Set on the creel, the climbing shoe 4 is fixedly connected to the elevator shaft shear wall 1 through embedded parts, and the guide rail 5 is set on the climbing shoe 4; in the construction state, the creel is fixed to the elevator through the climbing s...

Embodiment 2

[0039] Please continue to refer figure 1 with figure 2 This embodiment provides a construction method of a self-climbing monolithic tube frame system over a concrete volley beam, and the construction method includes the following steps:

[0040] Step 1. First install the climbing boots 4 through the embedded parts on the n layer, then install the lower part of the bearing frame 7, the wall attachment device 3 and the guide rail 5, and then install the remaining bearing frame 7 structure from bottom to top, where n is A natural number greater than or equal to 2. The load-bearing frame body 7 is mainly composed of truss layers to ensure its bearing capacity.

[0041] Step 2: After the load-bearing frame body 7 is installed, the longitudinal lifting steel beam 9 is installed first, then the horizontal lifting steel beam 10 is installed, and finally the lower hanging frame body 8 located in the middle of the tube frame is installed.

[0042] Step 3. After all the trusses are installed...

Abstract

The invention provides a concrete-overhead-beam crossing self-climbing integrated drum rack system and a construction method thereof, and belongs to the technical field of building construction. The problem that the elevator shaft construction efficiency of an independent tool type formwork system is low is solved. The system comprises bearing frame bodies, suspending frame bodies, lifting steel beams, large formworks, wall attaching devices, climbing shoes, guide rails and hydraulic systems. The large formworks and the climbing shoes are fixed to the two sides of an elevator shaft shear wall,the hydraulic systems are arranged on the bearing frame bodies, and the guide rails are arranged on the climbing shoes. The lifting steel beams are arranged on the tops of drum racks, the bearing frame bodies and the suspending frame bodies are hung on the lower portions of the lifting steel beams, and the bearing frame bodies are arranged on climbing machine positions at the two ends of an elevator shaft. The method includes the steps that the climbing shoes, the bearing frame bodies, the guide rails, the lifting steel beams and the suspending frame bodies are sequentially installed; construction layer rebars are bound, embedded parts are embedded, the large formworks are installed, concrete is poured, then a former layer of climbing shoes, lifting guide rails and climbing drum racks areinstalled, construction layer rebars are bound and the concrete is poured after climbing is completed, and construction is circulated sequentially.

Description

Technical field [0001] The invention belongs to the technical field of building construction, and specifically relates to a self-climbing integral tube frame system and a construction method for a concrete volley beam. Background technique [0002] For the traditional construction technology, the elevator shaft construction generally adopts the unit tool formwork system. Due to the obstacle of the concrete volley beam of the elevator shaft, each independent elevator shaft needs to set up an independent tool formwork system, and each unit shaft formwork is manually operated by a hoist. Independent lifting, cannot be lifted simultaneously as a whole, and each elevator hoistway needs to have at least two reserved holes on each floor to meet the layout of the formwork corbels, which not only has low construction efficiency, but also requires construction personnel to operate and improve on the formwork system , Which seriously affects construction safety and is difficult to apply to ...
