Description
Technical field
The utility model relates to foundation structure of building, is specially a kind of adjustable diagonal brace and reinforces foundation pit support device, belong to technical field of buildings.
Background technology
Diagonal brace many employings cast-in-place concrete structure of current building construction, subway station and tunnel internal support of foundation pit, cast-in-situ concrete is because need cast in situs maintenance, so needs is long in time limit, and the surrounding reserving inclined hole due to thrust block will arrange anti-shearing stiffener, add working procedure and difficulty of construction, nonetheless also often easily shear failure occurs.Owing to adopting reinforced concrete structure, so not recoverable, the support strength of the unadjustable braced structures of inclined support structure, and after basic engineering construction completes, generally all adopting the mode of explosion when removing diagonal brace, not only can bring environment pollution, also can produce a large amount of building castoff.
Utility model content
Object to be solved in the utility model proposes a kind of adjustable diagonal brace to reinforce foundation pit support device, not only structure is simple, easy construction sequence, improve programming, reduce cost, and effectively can avoid anti-shearing destruction of the prior art, the support strength of braced structures can be regulated according to constructional aspect, simultaneously construction material recoverable.
For achieving the above object, foundation pit support device reinforced by a kind of adjustable diagonal brace, it is characterized in that: this adjustable diagonal brace reinforces foundation pit supporting construction primarily of soldier pile, H type connector, flexible adjustable steel column, support pier, embedded bar and bottom girder, soldier pile is the some square piles be arranged at around foundation ditch, H type connector is the H profile steel part be arranged in soldier pile, two ends are symmetrical arranged steel plate, steel plate is of a size of 250mm*250mm, one end steel plate is embedded in square pile, one end steel plate is connected by the upper end of screw above with flexible adjustable steel column, flexible adjustable steel column realizes its length flexible by rotary handle, pier hole on the lower end of flexible adjustable steel column and support pier plugs, the hole depth in pier hole is 240 ~ 350mm, pier bore dia is greater than flexible adjustable steel column diameter 3mm, support pier is arranged at the substrate of foundation ditch and arranges with soldier pile one_to_one corresponding, pre-buried some embedded bars in support pier, embedded bar is 6, bar diameter is 10 ~ 20mm, by bottom girder consolidation between two adjacent support piers.
Further, described support pier is arranged at the substrate of foundation ditch and arranges with soldier pile one_to_one corresponding.
Further, pre-buried some embedded bars in described support pier, embedded bar is 6, and bar diameter is 10 ~ 20mm.
Compared with prior art, the beneficial effects of the utility model are: foundation pit support device reinforced by the adjustable diagonal brace of the one that the utility model proposes, not only structure is simple, easy construction sequence, improve programming, reduce cost, and effectively can avoid anti-shearing destruction of the prior art, the support strength of braced structures can be regulated, simultaneously construction material recoverable according to constructional aspect.
