The utility model has the advantages of simple structure, the interim support to the reinforcing bar has sufficient intensity, and the construction is simple, can be to the nervous condition of small cross section tunnel reinforced concrete lining construction period, makes the limit top arch reinforcing bar can utilize the period rapid transit of not concreting between the line production circulation to the region of planning the installation and deposit, helps making artifical transportation distance minimizing, and does not influence other process operations, does not damage finished product concrete when depositing.
Description
Technical Field
The utility model relates to a device of reinforcing bar is deposited to quick aerial frame behind concrete bottom plate lining cutting in limited space of underground tunnel is applicable to the quick aerial frame of bottom plate and deposits the reinforcing bar behind the small cross section tunnel lining cutting.
Background
Generally, the conventional small-section tunnel reinforced concrete lining adopts flow operation construction, namely, firstly, the bottom plate concrete is constructed, then the side arch reinforcing steel bars are installed, and then the side arch concrete is poured. Because the tunnel space is limited, the steel bar transportation road and the place of storing seriously are restricted, and the concrete pouring process can not transport the steel bars because of the influence of the occupied space of the mixer truck and the concrete pump truck, and can only transport the side top arch steel bars generally during the period of not pouring the concrete, but the strength of the bottom plate concrete is insufficient because of the completion of the pouring at the moment generally, and a large amount of steel bars can not be piled up. Otherwise, only manual carrying and installation while conveying are selected during concrete pouring; or the manual carrying strides over the floor concrete bin position just poured, but the two modes all have a lot of drawbacks, but adopt the manual carrying mode inefficiency, the haul distance is lengthened, the labour cost is high, and carry the reinforcing bar during concreting and disturb other operations greatly, seriously influence benefit and progress.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: to the above-mentioned problem, provide a built on stilts strorage device of limited tunnel space reinforcing bar, can utilize during not concreting with the required reinforcing bar transportation of limit top arch to just depositing and deposit on the bottom plate concrete face of accomplishing under the small cross section tunnel lining line production condition, do not damage the finished product concrete when just depositing. The utility model adopts the technical proposal that:
the utility model provides a carry out built on stilts strorage device of reinforcing bar fast behind concrete lining in limited tunnel space, pre-buried multirow PVC pipe on its characterized in that tunnel bottom plate concrete, multirow PVC pipe is partial to one side of tunnel bottom plate, and reserves the construction passageway at the opposite side of tunnel bottom plate, and the quantity of every row of PVC pipe is two and is separated by the certain distance, inserts fixed vertical steel pipe in the concrete in the PVC pipe of every row, and the built on stilts horizontal steel pipe of connection between two vertical steel pipes of every row connects and forms "H" type support that can deposit the reinforcing bar.
Further, the vertical steel pipe and the transverse steel pipe are connected through a fastener.
Furthermore, the distance between two PVC pipes in each row is 0.9-1.1 m, and the row distance of the PVC pipes is 1.4-1.6 m.
Further, the height of setting up of horizontal steel pipe is close the tunnel bottom plate.
Further, the height between the transverse steel pipe and the bottom plate of the tunnel is 9-10 cm.
The utility model has the advantages that: the utility model has the advantages of simple structure, the interim support to the reinforcing bar has sufficient intensity, and the construction is simple, can be to the nervous condition of small cross section tunnel reinforced concrete lining construction period, makes the limit top arch reinforcing bar can utilize the period rapid transit of not concreting between the line production circulation to the region of planning the installation and deposit, helps making artifical transportation distance minimizing, and does not influence other process operations, does not damage finished product concrete when depositing.

FIG. 1 is a typical floor plan of the present invention;
fig. 2 is a sectional view a-a of fig. 1.
Detailed Description
As shown in the figure, the utility model provides a built on stilts strorage device of limited tunnel space reinforcing bar is when little section tunnel reinforced concrete lining line production, for accomplishing artifical transport reinforcing bar apart from the minimizing, deposits a device of reinforcing bar and not damaging finished product concrete on the bottom plate concrete face of just pouring the completion, including following structure:
pre-buried multirow PVC pipe 2 before tunnel bottom plate concrete 1 pours, every row 2, the interval is about 1.5m, arranges in the one side of partial tunnel bottom plate, and reserves construction passage 6 at the opposite side.
In inserting pre-buried PVC pipe 2 with vertical steel pipe 3 after the initial set of bottom plate concrete 1, arrange horizontal steel pipe 4 between every row of left and right two vertical steel pipes 3, adopt fastener 5 to connect and form "H" type support, on 7 piles of reinforcing bar materials are deposited to "H" type support, wherein horizontal steel pipe 4 built on stilts sets up to preferably highly be close the tunnel bottom plate.
In this embodiment, the spacing between the PVC pipes 2 in the same row is about 1m, and the row spacing of the PVC pipes 2 is about 1.5 m. The transverse steel pipe 4 is about 10cm away from the concrete surface of the bottom plate.
The above description is only for the specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any person skilled in the art is in the field of the present invention, and all the changes or modifications are covered in the protection scope of the present invention.
