Embodiment
Below in conjunction with the accompanying drawings and embodiment is described in further detail the utility model.
As shown in figures 1 and 3, the utility model combination trestle is arranged in building foundation pit, is equipped with the building foundation pit
Inner support, the inner support include vertical supporting component and the lateral supports for being fixed on the vertical supporting component top, its
In, a plurality of subgrade cases 30 are equipped with the lateral supports.So as to which the vertical supporting component of inner support is as combination stack
The vertical supporting component 21 of bridge, the lateral supports of inner support are as the spandrel girder 25 for combining trestle, and subgrade case 30 is then made
To combine the trestle panel of trestle.
As shown in Figure 1, in the present embodiment, the building structure further includes diaphram wall 10；The inner support is also wrapped
Supporting beam 23 is included, the supporting beam 23 is arranged at the medium height position of vertical supporting component.The vertical supporting component can
Think steel column, column lower pillar stand stake etc., in the present embodiment, the vertical supporting component is lattice column 11.With reference to Fig. 3, at this
In embodiment, the lateral supports on inner support top are in groined type, are made of orthogonal horizontal beams of concrete 15, described
Subgrade case 30 is laid on the horizontal beams of concrete 15 of the groined type.
Further, with reference to Fig. 4, the subgrade case 30 has a skeleton, and the upper and lower surface of the skeleton is solid respectively
Surely there is a steel plate, the I-steel 33 that the skeleton is arranged in parallel by complex root is formed, and the steel plate is separately fixed at I-steel
The bottom surface of the top surface of 33 top flange plate and the bottom wing listrium of I-steel 33.It is preferred that it is fixed on the upper of the I-steel 33
The steel plate of edge of a wing plate top surface is decorative pattern checkered plates 31, and the steel plate for being fixed on the bottom wing listrium bottom surface of the I-steel 33 is tablet
Steel plate 32.Also, for subgrade case 30 when fixing, the tablet steel plate 32 of subgrade case 30 is close to the spandrel girder 25, subgrade case 30
Decorative pattern checkered plates 31 is then placed as trestle bridge floor for machine-walking or equipment, avoids sliding during Mechanical Moving, is occurred
Security incident.
Further, be equipped with built-in fitting 29 in the spandrel girder 25, the subgrade case 30 is when being laid with and the built-in fitting 29
It is welded and fixed, i.e., the tablet steel plate 32 of subgrade case 30 is welded and fixed with built-in fitting 29, so that subgrade case 30 is fixed on spandrel girder
On 25.
Further, as shown in Fig. 2, being provided with junction steel plate 40 between the adjacent subgrade case 30, the junction steel plate 40
It is fixed on subgrade case 30, i.e., junction steel plate 40 is fixed on the decorative pattern checkered plates 31 of subgrade case 30.The adjacent subgrade case
The quantity of junction steel plate 40 between 30 is a plurality of, which forms along between the adjacent subgrade case 30
Gap length direction be arranged at intervals.Further enhance the stability of combination trestle.
As shown in Figures 1 to 4, during the inner support construction of building structure, built-in fitting 29 is set in its lateral supports,
After the completion for the treatment of inner support construction, subgrade case 30 is laid with horizontal beams of concrete 15, make the tablet steel plate 32 of subgrade case 30 with it is pre-
Embedded part 29 is welded and fixed, and the decorative pattern checkered plates 31 of subgrade case 30 is the bridge floor for combining trestle at this time.Afterwards, adjacent described
Between subgrade case 30 a plurality of junction steel plates 40, a plurality of junction steel plates 40 are arranged at intervals along the length direction for forming gap
It is welded and fixed with the decorative pattern checkered plates 31 of adjacent subgrade case 30, thus, each subgrade case 30 connects into one by junction steel plate 40
It is overall, form overall trestle steel facing, there is provided the job platform and vehicle transport passage that pit earthwork excavates.On building ground
The lower structure construction stage, when trestle panel impacts Underground Construction, subgrade case 30 can not influence pattern foundation pit supporting structure
On the premise of carry out premature removal, and while removing, is not required to crush, very efficient and convenient, effectively reduces trestle panel to underground structure
The influence of construction.
The utility model combination trestle has the advantages that：
1) by the way of subgrade case is combined with inner support, substantially reduce the construction period, since subgrade case installation is simple and
