Description
Technical field
The invention belongs to technical field of building construction, be specifically related to a kind of foundation ditch recoverable concrete support.
Background technology
Along with the quickening of China's infrastructure construction, getting more and more at incity, city base pit engineering, foundation ditch is by perimeter bar
Part limits, and substantially cannot use and put slope digging mode, mostly selection 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, safety is high, but it performs 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 bigger；It is fast that steel pipe support sets up speed, repeatable utilization,
But rigidity is little, can only resistance to compression, it is impossible to shearing resistance, therefore foundation pit enclosure structure selects first to support to use concrete support mostly, its
Remaining support uses bracing members, and it is cast-in-place that this still can not solve concrete support, needs to wait for could excavating after its intensity reaches requirement
Foundation ditch, and the later stage to cut, it is impossible to the problem of recycling.
Summary of the invention
In order to solve the problems referred to above, the invention provides a kind of reusable foundation ditch first concrete support.
The technical solution adopted in the present invention is:
A kind of foundation ditch recoverable concrete support, it is characterised in that include precast support, building enclosure, central post, link
Beam, the middle part of described precast support is provided with the standard paragraphs being sequentially connected with and the connection of its two ends has junction, described adjacent
Between standard paragraphs, all it is connected by banjo fixing butt jointing between the standard paragraphs of end and junction；The top at described building enclosure two ends
Being provided with the supporting termination corresponding with junction, described supporting termination is provided with shearing resistance draw-in groove, described junction is arranged at
In shearing resistance draw-in groove, described shearing resistance draw-in groove, the position, gap of junction are filled by micro-expansion cement；It is provided with on described central post
Linking beam, described linking beam is arranged at the lower section of precast support.
Described central post is arranged at the middle part of described precast support.
It is provided with suspension hook on described standard paragraphs, junction.
Described building enclosure is diaphram wall or drilled pile.
The periphery of described 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.
Described banjo fixing butt jointing be internally provided with dowel, adjacent banjo fixing butt jointing is anchored by dowel.
The invention have the benefit that
Precast concrete supports recyclable recycling, saves construction costs, also can make foundation ditch first concrete support to the greatest extent simultaneously
Participate in structure stress soon, shorten the excavation of foundation pit time.

Between standard paragraphs 1, all it is connected by banjo fixing butt jointing 3 between the standard paragraphs 1 of end and junction 2；The top at building enclosure 10 two ends
Portion is provided with the supporting termination 4 corresponding with junction 2, and supporting is provided with shearing resistance draw-in groove 5 on termination 4, and junction 2 is arranged at anti-
Cutting in draw-in groove 5, shearing resistance draw-in groove 5, the position, gap of junction 2 are filled by micro-expansion cement 6；It is provided with on central post 7 and links
Beam 8, linking beam 8 is arranged at the lower section of precast support.
Central post 7 is arranged at the middle part of precast support.
It is provided with suspension hook 9 on standard paragraphs 1, junction 2.
Building enclosure 10 is diaphram wall or drilled pile.
The periphery of banjo fixing butt jointing 3 is provided with steel plate 12, and the steel plate 12 of adjacent banjo fixing butt jointing 3 pastes merga pass connecting bolt 13
Tighten together.
Banjo fixing butt jointing 3 be internally provided with dowel 14, adjacent banjo fixing butt jointing 3 is anchored by dowel 14.
