Abstract
The utility model relates to an interior bearing structure that steel sheet pile was strutted, including the rigid frame stand, gantry beam no. 1, gantry beam no. 2, the rigid frame stand is by H shaped steel welding in the larsen U shaped steel sheet pile outside, H shaped steel length weak point is in steel sheet pile length, the steel sheet is fixed to H shaped steel one end, foundation ditch edge symmetric distribution is followed to the rigid frame stand, stretch over and set up at least one deck gantry beam no. 1 on the symmetrical rigid frame stand of foundation ditch, set up at least one deck gantry beam no. 2 on the adjacent rigid frame stand of edge foundation ditch orientation, the rigid frame stand, the two mutual supports of gantry beam no. 1 and gantry beam form whole rigid -framed structure. The utility model discloses form three -dimensional rigid frame bearing structure system, the wholeness is good, and rigidity is great, well struts the effect to also reaching than the deep basal pit. In longer excavation supporting engineering, on one side can carry out the steel sheet pile and squeeze into, yi bian stride the installation gantry beam one by one, it is quick to erect simple to operate. Push up at the stand and directly erect the crossbeam, need not install components such as layer board in addition, simple process, construction speed is fast.
Description
Technical field
The utility model relates to steel sheet pile construction field, the inner supporting structure of particularly a kind of steel sheet pile supporting.
Background technology
In conventional steel sheet stake foundation pit supporting project, supporting form is generally, soldering pallet inside the steel sheet pile of foundation ditch direction, supporting plate is installed and encloses purlin (waist rail), then vertical in two gusset purlins (or at a certain angle) installs inner support, thus forms the support system of steel sheet pile supporting foundation pit inside.
The inner support system of general type, just a kind of plane structure, especially in some pipeline foundation pit supporting projects, often foundation ditch length is much larger compared with width, and foundation ditch is usually in not closed state, and this just makes to enclose purlin and inner supporting structure globality is more weak, and rigidity is less.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of inner supporting structure of steel sheet pile supporting, is introduced by rigid-framed structure in inner support system, strengthens the integral rigidity of inner support system.
For achieving the above object, the utility model realizes by the following technical solutions:
A kind of inner supporting structure of steel sheet pile supporting, comprise rigid frame column, gantry beam one, gantry beam two, rigid frame column is welded on outside the U-shaped steel sheet pile of Larsen by H profile steel, H profile steel is shorter in length than steel sheet pile length, H profile steel one end fixation steel plate, rigid frame column is symmetrical along margin of foundation pit, at least one layer of gantry beam one is set up across on the Symmetric Rigid Frames column of foundation ditch, set up at least one layer of gantry beam two along on the adjacent rigid frame column in foundation ditch direction, rigid frame column, gantry beam one and gantry beam two mutually support and form overall rigid-framed structure.
Distance steel sheet pile end, the H profile steel end 1-2 rice of described rigid frame column, prepared screw-bolt hole on steel plate.
Web both sides, described gantry beam two termination welding equal leg angle, prepared screw-bolt hole on angle steel.
Described gantry beam two is arranged on the termination, one end of gantry beam one, gap between gantry beam two frange plate and gantry beam one frange plate, the steel plate of welding and frange plate stack pile.
Compared with prior art, the beneficial effects of the utility model are:
(1) form three-dimensional strut structural system, good integrity, rigidity is comparatively large, also can reach good supporting effect for comparatively deep foundation ditch.
(2) in longer foundation pit supporting project, steel sheet pile can be carried out and squeeze into, by cross gantry beam is installed on one side, set up fast easy for installation.
(3) rigid frame column welds with steel sheet pile, together squeezes in soil, directly sets up crossbeam on column top, separately need not install the components such as supporting plate, and technique is simple, and speed of application is fast.
(4) groundwater table can be widely used in not high, in the foundation pit supporting projects such as the building foundation pit that foundation ditch width is not too large, pipeline foundation ditch, especially poor for geology soil layer, pair of interior support stabilized soil pavement requires higher base pit engineering, good effect can be played, simultaneously for the foundation pit supporting project that construction period is urgent, its advantage can be played equally.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further illustrated:
Embodiment
As Figure 1-Figure 2, a kind of inner supporting structure of steel sheet pile supporting, comprise rigid frame column, gantry beam 1, gantry beam 23, rigid frame column is welded on outside the U-shaped steel sheet pile 4 of Larsen by H profile steel 1, H profile steel 1 is shorter in length than steel sheet pile 4 length, steel sheet pile head exceeds H profile steel 1.2 meters, afterbody H profile steel is short compared with steel sheet pile 2 meters, H profile steel 1 top solder steel plate I6, prepared screw-bolt hole on steel plate I6, rigid frame column is symmetrical along margin of foundation pit, at least one layer of gantry beam 1 is set up across on the Symmetric Rigid Frames column of foundation ditch, at least one layer of gantry beam 23 is set up along on the adjacent rigid frame column in foundation ditch direction, rigid frame column, gantry beam 1 and gantry beam 23 mutually support and form overall rigid-framed structure.
As Figure 4-Figure 6, web both sides, gantry beam two termination welding 75x6 equal leg angle 5, prepared screw-bolt hole on angle steel 5, gantry beam 23 is arranged on the termination, one end of gantry beam 1, first connect with bolt, after weld, gap between gantry beam 23 frange plate and gantry beam 1 frange plate, welding and the steel plate II 8 of frange plate stack pile.Weld corner 10 between rigid frame column with gantry beam 1, inside rigid frame column and gantry beam one, weld stiffening rib I, stiffening rib II respectively with corner termination correspondence position.
Be only general principle of the present utility model above, not impose any restrictions the utility model, every foundation the utility model carries out equivalent variations and modification to it, all within the category of the art of this patent protection scheme.
