Description
Technical field
The utility model belongs to project building construction technical field, especially a kind of foundation ditch late poured band support structure.
Background technology
At present, along with the fast development of China's urban construction, land resources for building is deficient, high-rise, super highrise building continues to bring out, underground space development scale is also increasing, more and more darker, and building surrounding enviroment also become increasingly complex, periphery low-rise building, have pressure pipeline etc. to have for pattern foundation pit supporting structure distortion size to be comparatively strict with.Therefore pattern foundation pit supporting structure, support replacement constructure scheme need to consider horizontal support rigidity and deformation rate own in formulation process.In order to ensure the globality of structure and the impermeability of basement structure, ater-casting form usually can be adopted as the provisional deformation joint of reserved location in present integral reinforced concrete structure.
But the horizontal force made in horizontal structure cannot transmit by arranging of ater-casting, cause structural entity poor rigidity, stability bad, the structural safety of ater-casting and foundation ditch can not be ensured.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of foundation ditch late poured band support structure is provided, this structural entity rigidity is large, good stability, constructing operation are easy, speed of application is fast, applied widely, and use manpower and material resources sparingly, the structural safety of ater-casting and foundation ditch can be ensured.
Scheme of the present utility model is achieved in that
A kind of foundation ditch late poured band support structure, comprise shaped steel, cage of reinforcement net, fast-easy closing-up net and steel plate for sealing water, described steel plate for sealing water horizontal interval be arranged in parallel and is positioned at the both sides of ater-casting, this steel plate for sealing water upper, cage of reinforcement net is vertically installed respectively in lower surface, on this, the opposite exterior lateral sides of lower two groups of cage of reinforcement nets respectively note covers installation fast-easy closing-up net, multiple shaped steel is installed in steel plate for sealing water upper surface between described cage of reinforcement net respectively horizontal parallel interval, the steel plate for sealing water upper surface of the fast-easy closing-up net opposite exterior lateral sides corresponding with this shaped steel is same installs multiple shaped steel, outside fast-easy closing-up net, shaped steel and the shaped steel between cage of reinforcement are on same straight line,
The horizontal opposite exterior lateral sides face being positioned at the shaped steel outside described fast-easy closing-up net respectively uniform intervals is fixedly mounted with multiple peg.
Advantage of the present utility model and good effect are:
1, this structure is by installing shaped steel in position, ater-casting, and work progress does not take critical circuits, and do not affect other operations and normally carry out, constructing operation is easy.
2, the shaped steel power transmission in this structure supports uniform force, and integral rigidity is large, good stability, and the power transmission of this shaped steel supports mainly bears shaped steel axial compression, and the force transferring structure of shaped steel can be considered two ends fixed structure, and therefore resistance to overturning is good, applied widely.
3; the utility model integral rigidity is large, good stability, constructing operation are easy, speed of application is fast, applied widely; and use manpower and material resources sparingly; the structural safety of ater-casting and foundation ditch can be ensured, be particularly useful for the large-scale excavation engineering that the construction period is urgent, strict to surrounding enviroment protection requirement, the excavation of foundation pit degree of depth is large, complex-shaped.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail.
A kind of foundation ditch late poured band support structure, as shown in Figure 1, comprise shaped steel 2, cage of reinforcement net 5, fast-easy closing-up net 4 and steel plate for sealing water 7, described two steel plate for sealing water horizontal intervals be arranged in parallel and are positioned at the both sides of ater-casting 6, two steel plate for sealing water upper, cage of reinforcement net is vertically installed respectively in bottom, the opposite exterior lateral sides of these two groups of cage of reinforcement nets respectively note covers installation fast-easy closing-up net, between described two cage of reinforcement nets the steel plate for sealing water upper surface of (i.e. ater-casting) respectively horizontal parallel interval multiple shaped steel is installed, the steel plate for sealing water upper surface of described two the symmetrical fast-easy closing-up net opposite exterior lateral sides corresponding with this shaped steel is same installs multiple shaped steel, outside fast-easy closing-up net, shaped steel and the shaped steel between cage of reinforcement are on same straight line.Shaped steel is set in ater-casting and can transmits horizontal force, and the shear stiffness of the shear stiffness opposite concrete beam of shaped steel is much smaller, thus can not retrain the free settling of both sides, ater-casting monomer, selected shaped steel sectional dimension and shaped steel spacing are determined all as requested.
In the present embodiment, described in be positioned at shaped steel outside fast-easy closing-up net horizontal opposite exterior lateral sides face respectively uniform intervals be fixedly mounted with multiple peg 3.
Construction method of the present utility model is:
Step one, 1/2 Lower Half of floor 1 thickness in position, ater-casting installs cage of reinforcement net, and installs fast-easy closing-up net outside cage of reinforcement net;
Step 2, at cage of reinforcement net and the fast-easy closing-up net upper surface welding steel plate for sealing water of Lower Half;
Step 3, lays shaped steel according to the steel plate for sealing water upper surface of design code spacing between two cage of reinforcement nets;
Step 4, installs cage of reinforcement net and fast-easy closing-up net in steel plate for sealing water upper surface.
This structure is by installing shaped steel in position, ater-casting, and work progress does not take critical circuits, and do not affect other operations and normally carry out, constructing operation is easy; Support integral uniform force is propped up in shaped steel power transmission, and integral rigidity is large, good stability.The power transmission of shaped steel supports mainly bears shaped steel axial compression, and the force transferring structure of shaped steel can be considered two ends fixed structure, and therefore resistance to overturning is good, applied widely.The utility model is widely used in having in the basement structure support replacement construction of ater-casting, be particularly useful for the construction period urgent, strict, that the excavation of foundation pit degree of depth is large, complex-shaped large-scale excavation engineering is required to surrounding enviroment protection.
It is emphasized that; embodiment described in the utility model is illustrative; instead of it is determinate; therefore the utility model comprises the embodiment be not limited to described in detailed description of the invention; every other embodiments drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope of the utility model protection equally.
