Technical field
The utility model relates to a kind of sole plate reinforcing cage of concreting, especially a kind of prefabricated panel reinforcing cage that is used for directly over the subway tunnel.
Background technology
Entered since 21st century, urban construction has welcome another climax of taking turns, track traffic since its have fast, advantage such as environmental protection, capacity are huge and become the public transit facility of many big and medium-sized cities first-selection gradually.The development of the synchronous high-speed of underground construction and track traffic is being faced the engineering interface of the international metropolis as Shanghai and increasing is carried out the activity of large-scale foundation pit construction at the tunnel upper of building track traffic.
When the foundation ditch below was the track traffic facility of just runing, because the track traffic facility in the operation is high to the Deformation control requirement, this class construction activities was a forbidden zone of engineering circle always.If can break through this technology " forbidden zone " of engineering circle, will produce tangible society, environment and economic benefit.
According to Shanghai subway operation Co., Ltd to track traffic safeguard protection zone operation scheme technological audit suggestion: be positioned at the foundation ditch block construction directly over the subway, single width (each piecemeal) the whole construction time is controlled in seven hours and finishes.The single width whole contents comprises shoveling, soffit formwork (bed course), reinforcing bar binding, upright side template, concreting.
The reinforcing bar of general base arrangement is at the construction field (site) with vertical main reinforcement and horizontal main reinforcement, and layering is closely arranged with the lattice word shape that forms matrix pattern, imposes false fixingly at last with lametta, promptly is commonly called as reinforcing bar binding; The top reinforcement support is set up at the scene, and steel plate for sealing water, side template are installed; And base arrangement block construction or piecemeal are not bigger.
The single width whole construction time will be controlled in seven hours and finish, and obviously adopting traditional reinforcing cage to organize cube formula at the scene can't be effectively, finish on time.Thereby the method for prefabricated panel reinforcing cage is arisen at the historic moment.
Summary of the invention
The purpose of this utility model is that sole plate reinforcing cage directly over a kind of subway tunnel of can be in batches prefabricated, finishing fast will be provided.
For achieving the above object, the technical solution of the utility model is: sole plate reinforcing cage directly over a kind of subway tunnel, by the bottom layer of the reinforcing steel cage, the group staking, top reinforcement is formed, and is characterized in: the bottom layer of the reinforcing steel cage is made of horizontal main reinforcement, vertical main reinforcement, support vertical reinforcement, support level reinforcing bar, support oblique rollering steel muscle, steel plate for sealing water, wire lath sheet template and suspension hook; Group staking structure is made of framework reinforcing bar and spacer bars.
Below the group staking, the bottom layer of the reinforcing steel cage discharges its vertical, horizontal main reinforcement with the matrix pattern clathrate, and on each intersection point, fix with the fine wire colligation successively, welding is fixed on each intersection point of vertical, horizontal main reinforcement, the fixing one reinforcing cage that forms of support vertical reinforcement, steel plate for sealing water, support level reinforcing bar and the welding of wire lath sheet template or colligation.
Base plate top reinforcement cage is made of main reinforcement, suspension hook, and wherein, main reinforcement is with the discharging of matrix pattern clathrate, and welding is fixed on the intersection point, and is fixed in above the group staking.Bottom layer of the reinforcing steel cage and base plate top reinforcement cage are all reserved overlap joint section or anchoring section at the termination and the two ends of main reinforcement, are connected with avris piecemeal overlap joint; Suspension hook is welded on respectively on bottom layer of the reinforcing steel cage and the base plate top reinforcement cage downside vertical reinforcement.
The beneficial effects of the utility model are: sole plate reinforcing cage of the present utility model can be prefabricated in batches, when being used in combination, by crane reinforcing cage is hung in construction foundation pit, can finish the base plate of foundation pit reinforcing bar binding fast, set up Steel bar rack, steel plate for sealing water and side template are installed, thereby reach the purpose of this utility model.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
Sole plate reinforcing cage directly over the subway tunnel of the present utility model, by the bottom layer of the reinforcing steel cage, the group staking, top reinforcement is formed.
As shown in Figure 1, the utility model base plate bottom layer of the reinforcing steel cage is made of horizontal main reinforcement 1, vertical main reinforcement 2, support vertical reinforcement 5, support level reinforcing bar 8, support oblique rollering steel muscle 6, steel plate for sealing water 9, wire lath sheet template 7 and suspension hook 10.It includes the termination and overlap joint section or anchoring section 3,4 are reserved in two ends.During enforcement, steel plate for sealing water 9 and wire lath sheet template 7 need be done corresponding adjustment according to each piecemeal, and for example first piecemeal will be provided with around then.If be provided with steel plate for sealing water 9 and 7 relative set supports of wire lath sheet template oblique rollering steel muscle 6, otherwise support vertical reinforcement 5, support level reinforcing bar 8 can correspondingly reduce.Overlap joint section or anchoring section 3,4 are reserved in termination and two ends, and when meeting the termination of whole base plate of foundation pit, reinforcing cage will not be provided with in whole base plate termination side and reserve overlap joint section 3,4, then reserve anchoring section by corresponding code requirement, and other all is to reserve overlap joint section 3,4.Suspension hook 10 is welded on the reinforcing cage downside reinforcing bar.
