Abstract
The utility model discloses a steel platform of use is demolishd in shoring of trench mainly includes the steelframe and lays steel sheet on the steelframe, the steelframe constitutes rectangular frame by two girders and two secondary beams still be equipped with the secondary beam that two piece at least secondary beams are on a parallel with one side among the rectangular frame in the rectangle steelframe set up two piece at least channel -section steel stiffening ribs between the secondary beam, the channel -section steel stiffening rib is in the coplanar with the steelframe, and the perpendicular to the secondary beam, the activity of steelframe bottom sets up four planar steel columns of perpendicular to steelframe, just the steel column is in steelframe bottom interval is adjustable. The utility model discloses platform frame establishes easy and simple to handlely, and the site operation of being convenient for is not used in the underfloor and sets up full hall scaffold, has practiced thrift the cost in a large number, improves the turnover utilization ratio of steelframe, can also effectively protect the finished product major structure simultaneously, sets up the shock insulation backing plate in the stand bottom simultaneously, can reduce the vibrations in the work progress through column base shock insulation backing plate, avoids leading to the fact destruction to the finished product floor.
Description
Technical field
The utility model relates to a kind of steel platform, and the steel platform of a kind of foundation ditch supporting removal use specifically, belongs to foundation ditch construction project technical field.
Background technology
For large deep foundation pit, the general form of structure adopting inner support, steel post, concrete horizontal supports.More than the basement number of plies is two-layer, more than the support number of plies is two-layer.Along with the construction of Main Underground body structure, concrete horizontal supports and also will successively remove from bottom to top.Concrete support method for dismounting generally adopts pick machine to remove in order.Pick machine, in dismounting support process, on needing to stand in and constructing finished product floor complete, in order to ensure the structural safety of floor, needing to set up full hall scaffold at underfloor, supporting the operation load of pick machine.So just cause underfloor full hall scaffold needs etc. can remove after the supporting removal of upper strata, be unfavorable for the turnover of template scaffold, add cost.
Utility model content
Technical problem to be solved in the utility model is, for the shortcoming of above prior art, proposes the steel platform that a kind of foundation ditch supporting removal uses; steel platform is adopted to replace scaffold; not be used in underfloor and set up full hall scaffold, available protecting finished product agent structure, has saved cost.
In order to solve the problems of the technologies described above, the technical solution of the utility model is achieved in the following ways: provide the steel platform that a kind of foundation ditch supporting removal uses, mainly comprise steelframe and be laid on the steel plate on described steelframe, described steelframe forms rectangular frame by two girders and two secondary beams, the secondary beam that at least two secondary beams are parallel to side in rectangular frame is also provided with in described rectangle steelframe, at least two channel-section steel stiffening ribs are set between described secondary beam, described channel-section steel stiffening rib and steelframe are in same plane, and perpendicular to described secondary beam; Bottom described steelframe, activity arranges four steel columns perpendicular to steelframe plane, and described steel column is adjustable at described steelframe bottom space.
The utility model limits technical scheme further: the steel platform that aforesaid foundation ditch supporting removal uses, and is provided with shock insulation backing plate, can reduces the vibrations in work progress bottom described steel column, reduces the vibrations of construction to floor level.
Aforesaid foundation ditch supporting removal steel platform, described steel plate is the checkered steel plate that 10mm is thick.
Further, the steel platform that aforesaid foundation ditch supporting removal uses, in order to ensure the intensity of steelframe, described girder and secondary beam are channel-section steel.
The beneficial effects of the utility model are: the erection of the utility model platform is easy and simple to handle; be convenient to site operation; not be used in underfloor and set up full hall scaffold; substantial saving in cost; improve the turnover utilization rate of steelframe, simultaneously can also available protecting finished product agent structure, shock insulation backing plate is set in column bottom simultaneously; the vibrations in work progress can be reduced by suspension column shock insulation backing plate, avoid damaging finished product floor.

Fig. 2 is the utility model A-A sectional view.
Detailed description of the invention
Below the utility model is described in further detail:
embodiment 1
The steel platform that a kind of foundation ditch supporting removal that the present embodiment provides uses, structure as depicted in figs. 1 and 2, mainly comprise steelframe and be laid on the steel plate 4 on steelframe, steel plate is the checkered steel plate that 10mm is thick, steelframe forms rectangular frame by two girders 1 and two secondary beams 2, in rectangle steelframe, be also provided with the secondary beam 2 that two secondary beams are parallel to rectangle steelframe side, girder and secondary beam are channel-section steel; Between secondary beam, arrange two channel-section steel stiffening ribs 3, channel-section steel stiffening rib and steelframe are in same plane, and perpendicular to secondary beam; Bottom steelframe, activity arranges four and is provided with shock insulation backing plate 6 bottom steel column perpendicular to the steel column 5 of steelframe plane, and steel column is adjustable at steelframe bottom space.
When the present embodiment uses, first by steel platform two ends totally four steel columns 5 be bearing on concrete floor two Pin main beam in frame 7, steel column is along with the difference of main beam in frame spacing, adjustment spacing can be moved freely below girder, thus guarantee that the operation load of steel platform passes to main beam in frame 7, then pass on the frame column of concrete main body structure, avoid concrete floor and beam to be affected.Pick machine stands on steel platform and carries out operation, and same steel platform makes two, connects together, and changes for pick wheel.Because steel platform weight is very light, with tower crane shift position at any time, pick machine can be facilitated to change position and to carry out operation.
Above embodiment is only and technological thought of the present utility model is described; protection domain of the present utility model can not be limited with this; every technological thought according to the utility model proposes, any change that technical scheme basis is done, all falls within the utility model protection domain.
Claims (4)
