Description

A kind of foundation ditch recoverable concrete support
Technical field
This utility model belongs to technical field of building construction, and in particular to a kind of foundation ditch recoverable concrete support.
Background technology
With the quickening of China's infrastructure construction, in city incity, base pit engineering is more and more, and foundation ditch is subject to perimeter bar Part is limited, and cannot be adopted substantially slope digging mode, mostly be selected vertical type building enclosure(Diaphram wall or drilled pile)+ interior Support as foundation pit supporting system.Conventional inner support has reinforced concrete support and steel pipe support, reinforced concrete support rigidity Greatly, control deform, can resistance to compression, also can shearing resistance, it is safe, but which is performed often by cast-in-place mode, and later stage need Cut, cause that its working procedure is loaded down with trivial details, the construction period is longer, investment is larger;Steel pipe support sets up speed soon, repeats and utilizes, But rigidity is little, can only resistance to compression, it is impossible to shearing resistance, therefore foundation pit enclosure structure selects first support to adopt concrete support mostly, its Remaining support adopts bracing members, and it is cast-in-place that this still can not solve concrete support, needs to wait for excavate after its intensity reaches requirement Foundation ditch, and the later stage to cut, it is impossible to the problem of recycling.
Utility model content
In order to solve the above problems, this utility model is there is provided a kind of first concrete of reusable foundation ditch Support.
The technical scheme adopted by this utility model for:
A kind of foundation ditch recoverable concrete support, it is characterised in that including precast support, building enclosure, central post, company Binder, is provided with the standard paragraphs that are sequentially connected and its two ends is connected with junction in the middle part of the precast support, described adjacent Standard paragraphs between, be connected by banjo fixing butt jointing between the standard paragraphs of end and junction;The top at the building enclosure two ends Portion is provided with supporting termination corresponding with junction, and shearing resistance draw-in groove is provided with the supporting termination, and the junction is arranged In shearing resistance draw-in groove, the shearing resistance draw-in groove, the gap position of junction are filled by micro-expansion cement;Arrange on the central post There is linking beam, the linking beam is arranged at the lower section of precast support.
The central post is arranged at the middle part of the precast support.
Suspension hook is provided with the standard paragraphs, junction.
The building enclosure is diaphram wall or drilled pile.
The periphery of the banjo fixing butt jointing is provided with steel plate, the steel plate patch merga pass connecting bolt fastening of adjacent banjo fixing butt jointing Together.
The banjo fixing butt jointing is internally provided with dowel, and adjacent banjo fixing butt jointing anchored by dowel.
The beneficial effects of the utility model are:
Precast concrete supports recyclable recycling, saves construction costs, while can also make first concrete of foundation ditch Support participates in structure stress as early as possible, shortens the excavation of foundation pit time.
