The utility model content
The utility model has been designed and developed a kind of subway solid concrete roabed shrinkage joint and has been built servicing unit, purpose is in order to solve the not good shrinkage joint quality that affects of shrinkage joint plate fixed effect, restive standard and the problem such as labor intensive is large, efficient is low when rejecting upper strata 30mm separator strip.
The technical scheme that the utility model provides is: servicing unit is built at a kind of subway solid concrete roabed shrinkage joint, it is characterized in that, comprising:
Tubular element, its longitudinal section are rectangle;
Annular component, it is arranged on the top of described tubular element; And
Syndeton, it comprises through hole and the first securing member, and wherein, described through hole connects the upper and lower of described tubular element, and described the first securing member passes described through hole from top to bottom.
Preferably, the distance between the upper and lower of described tubular element is more than or equal to 30mm.
Preferably, described subway solid concrete roabed shrinkage joint is built servicing unit and is also comprised:
A pair of supporting member, each supporting member comprise by a horizontal-extending section and a vertical extension;
Wherein, described tubular element is arranged on the below of described a pair of supporting member, and two ends removably are connected to respectively the horizontal-extending section of described a pair of supporting member, and the length direction of described tubular element and the length direction of each supporting member are perpendicular.
Preferably, the horizontal-extending section of each supporting member has a bar hole that extends along the length direction of this supporting member; Described servicing unit also comprises a pair of screw rod, and a screw rod is fixed on an end of described tubular element, extends upward, and passes the bar hole of a supporting member, and the other end of this screw rod is fixed on the top of described bar hole by a nut.
Preferably, the horizontal-extending section of each supporting member comprises two parts of the both sides that are positioned at vertical extension, and one of them part offers bar hole, and another part is the two rectangle steel discs that are welded on vertical extension.
Preferably, described tubular element comprises two tubular portions, two tubular portion docking, the top of the docking location of described two tubular portions is provided with the connector of this docking location of leap, and described connector is fixed on two tubular portions by a plurality of the second securing members.
Preferably, described the first securing member is steel nail.
The beneficial effects of the utility model are that steel nail is connected tubular element and is connected with the shrinkage joint plate, solved conventional method shrinkage joint plate fixed effect not good, easily tilt to twist, so that the shrinkage joint of making produces distortion, construction precision is difficult to the problems such as control, and disposable making moulding is used for the upper strata pitch hemp cut groove that binds, and does not need secondary to reject upper strata 30mm separator strip.The utility model integral manufacturing is simple, and is easy to operate, and increases substantially efficiency of construction, construction precision when reducing labour intensity, labour.
Description of drawings
Fig. 1 is the plan structure schematic diagram that servicing unit is built at a kind of subway solid concrete roabed described in the utility model shrinkage joint.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the manual literal to make those skilled in the art.
As shown in Figure 1, two tubular elements 5 are stitched together, and connector 7 are placed on the top of two tubular elements, 5 splicings place, tighten the second fastener bolt 6, two tubular elements 5 are connected and fixed, be screwed on tubular element 5 nuts 3 screw rod one end fixing; Each supporting member 2 is horizontal above two sleepers, one end, and screw rod is inserted in each supporting member 2 horizontal-extending section bar hole 4, be fixedly connected with by nut afterwards; The shrinkage joint plate is inserted the subway solid concrete roabed shrinkage joint fix builds under the servicing unit, steel nail is hammered into hole through hole 1, tubular element 5 and shrinkage joint plate are linked together, servicing unit is built at the subway solid concrete roabed shrinkage joint that connects and the shrinkage joint plate is adjusted to the accurately position at shrinkage joint again; Carry out that solid concrete roabed is built and will grow the wedge shape steel and imbed 30mm, each supporting member 2 of dismounting reached the fixedly steel nail of shrinkage joint plate after railway roadbed was molded into prescribed strength, the screw rod of back-outing, turn on the second fastener bolt 6, remove connector 7, by annular component 8 tubular element 5 is prized from concrete, two tubular elements 5 are extracted from the rail both sides, the 30mm groove one-shot forming of upper strata, shrinkage joint.
Described each supporting member is angle steel, angle steel comprises two orthogonal sides, vertically the side is vertical extension, vertically the lateral surface uniform welding of extension has two rectangle steel discs 9, two rectangle steel discs 9 consist of horizontal-extending section with the side 4 that another has bar hole, when using subway solid concrete roabed shrinkage joint to build servicing unit, two rectangle steel discs 9 are inserted below the rail, vertically the adjacent rail of extension is inboard, can prevent that so the whole floating of servicing unit is built at subway solid concrete roabed shrinkage joint in building the process of railway roadbed.
