Abstract
The utility model discloses an exhaust device for a bottom mould of a needle beam trolley. The exhaust device comprises a locking nut, an adjusting nut, a supporting angle steel, an adjusting bolt and a plugging plate, wherein a U-shaped slot is arranged on a horizontal section at the top end of the supporting angle steel; the lower end of the adjusting bolt is welded with the plugging plate; and the upper end of the adjusting bolt is fixedly blocked in the U-shaped slot on the horizontal section of the supporting angle steel through the locking nut and the adjusting nut. The exhaust device for the bottom mould of the needle beam trolley has the beneficial effects that most air between the concrete and a panel of the bottom mould is thoroughly exhausted, the generation of air holes and burrs is greatly reduced, a lining surface is smoother and the work load of post-processing is reduced.
Description
Technical field
The utility model relates to the exhaust plant technical field, particularly a kind of exhaust plant that is used for needle beam chassis bed die.
Background technology
In the present needle beam chassis Second Lining Construction, because of needle beam pallet bottom meeting residual fraction air, this just causes can staying a large amount of pores and burr behind the concrete formation.Therefore, the technology that haves much room for improvement, otherwise quality can not get guaranteeing behind the concrete formation.
The utility model content
The goal of the invention of the utility model is: the problem to above-mentioned existence provides a kind of exhaust plant that is used for needle beam chassis bed die.
The technical scheme that the utility model adopts is such: a kind of exhaust plant that is used for needle beam chassis bed die; Comprise locking nut, adjustment nut, supporting angle steel, adjusting bolt and shutoff plate; The horizontal segment on said supporting angle steel top is provided with U type groove; Said adjusting bolt lower end is welded on the shutoff plate, and the upper end is through in locking nut and the U type groove of adjustment nut fixed card on the supporting angle steel horizontal segment.
As preferably, the isosceles trapezoid that the cross section of said shutoff plate is big up and small down.
In sum; Owing to adopted technique scheme, the beneficial effect of the utility model is: can guarantee to get rid of the most of air between clean concrete and the bed die panel, significantly reduce the generation of pore and burr; Make the lining cutting surface brighter and cleaner, reduced the workload of post-processed.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Mark among the figure: 1 is locking nut, and 2 are the adjustment nut, and 3 is supporting angle steel, and 4 for regulating bolt, and 5 are the shutoff plate.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
As shown in Figure 1; A kind of exhaust plant that is used for needle beam chassis bed die; Comprise locking nut 1, adjustment nut 2, supporting angle steel 3, regulate bolt 4 and shutoff plate 5; The horizontal segment on said supporting angle steel 3 tops is provided with U type groove, and said adjusting bolt 4 lower ends are welded on the shutoff plate 5, and the upper end is through in locking nut 1 and the U type groove of adjustment nut 2 fixed card on supporting angle steel 3 horizontal segments.
The isosceles trapezoid that the cross section of said shutoff plate 5 is big up and small down.
In the tunnel lining construction; Elder generation's concrete perfusion, the lower end of supporting angle steel 3 is welded on the bed die panel of needle beam chassis, and shutoff plate 5 is in separated position with the bed die panel of needle beam chassis; Treat that concrete arrives the steam vent place and regulates adjustment nut 2 again; Shutoff plate 5 is closely contacted with needle beam chassis bed die panel, with locking nut 1 locking, continue concrete perfusion more then.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
