Abstract

The utility model discloses a movable bottom-formwork structure at a precast beam slab bearer, which has the characteristic that the elevation adjustment efficiency can be improved. The movable bottom-formwork structure at the precast beam slab bearer comprises a bearer bottom-formwork steel plate and fixed bottom-formwork steel plates, wherein the fixed bottom-formwork steel plates are positioned at two ends of the bearer bottom-formwork steel plate and are separated from the bearer bottom-formwork steel plate. The bottom parts of the fixed bottom-formwork steel plates are provided with fixed pedestals, and the bearer bottom-formwork steel plate is provided with adjusting screws which can let the bearer bottom-formwork steel plate to move up and down. When the elevation of the bearer bottom-formwork steel plate needs to be adjusted, the adjusting screws are turned to butt or pull the bearer bottom-formwork steel plate to move up and down, and therefore the needed gradient of a precast beam above the bearer bottom-formwork steel plate is adjusted. Compared with the mode that a sand mat or a wood wedge is adopted for adjusting, the movable bottom-formwork structure has the advantages of convenient adjustment, easy operation and construction cost reducing, can improve the adjustment efficiency to the elevation of the bearer bottom-formwork steel plate at the same time, and is especially suitable for spread and application on the movable bottom-formwork structure at the precast beam slab in the bridge engineering.

The utility model content

Technical problem to be solved in the utility model provides a kind of movable bed die structure in precast beam bearing place that elevation is adjusted efficient that improves.

The technical scheme that its technical problem that solves the utility model adopts is: the movable bed die structure in precast beam bearing place, comprise bearing bed die steel plate and be positioned at bearing bed die steel plate two ends and with the separated fixedly bed die of bearing bed die steel plate steel plate, fixedly bed die steel plate bottom is provided with fixed base, and bearing bed die steel plate place is provided with the adjustment screw that bearing bed die steel plate is moved up and down.

Further be, bearing bed die steel plate below is a hollow structure, is provided with at least three sleeves in bearing bed die steel plate bottom surface, is set with nut in sleeve, and adjustment screw is connected with nut thread.

As optimal technical scheme, described sleeve has four, is separately positioned on the place, four angles, bottom surface of bearing bed die steel plate.

Further be that bearing bed die steel plate is provided with the through hole over against sleeve.

Further be, the top of adjustment screw is interior hexagonal structure, and the bottom is the outer-hexagonal structure.

Further be, at bearing bed die steel plate and fixedly be provided with free extendable room between the bed die steel plate.

The beneficial effects of the utility model are: by the setting of adjustment screw, when needs are adjusted the elevation of bearing bed die steel plate, can be by this adjustment screw of turn, adjustment screw is pushed or spur bearing bed die steel plate and move up and down, thereby adjust the gradient of bearing bed die steel plate top precast beam design, with respect to the mode that adopts placing sand layer or timber wedge to adjust, it is easy to adjust, and be beneficial to operation, can reduce construction cost, can improve simultaneously adjusting efficient, be particluarly suitable for applying on the movable bed die structure in bridge engineering precast beam bearing place bearing bed die steel plate elevation.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the sectional view of A-A direction among Fig. 1.

Be labeled as among the figure: bearing bed die steel plate 1, fixedly bed die steel plate 2, fixed base 3, adjustment screw 4, sleeve 5, nut 6, free extendable room 7, through hole 8, ground 9.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As Fig. 1 and shown in Figure 2, the movable bed die structure in precast beam bearing of the present utility model place, comprise bearing bed die steel plate 1 and be positioned at bearing bed die steel plate 1 two ends and with bearing bed die steel plate 1 separated fixedly bed die steel plate 2, fixedly bed die steel plate 2 bottoms are provided with fixed base 3, and bearing bed die steel plate 1 place is provided with the adjustment screw 4 that bearing bed die steel plate 1 is moved up and down.Setting by this adjustment screw 4, when needs are adjusted the elevation of bearing bed die steel plate 1, can be by this adjustment screw 4 of turn, make adjustment screw 4 push or spur bearing bed die steel plate 1 and move up and down, thus the gradient of adjustment bearing bed die steel plate 1 top bridge, with respect to the mode that adopts placing sand layer or timber wedge to adjust, it is easy to adjust, and be beneficial to operation, can reduce construction cost, can improve adjusting efficient simultaneously bearing bed die steel plate 1 elevation.

In the above-described embodiment, bearing bed die steel plate 1 bottom can be provided with supporting construction, adjustment screw 4 is threaded in the elevation of realizing in this supporting construction bearing bed die steel plate 1 regulates; Also can directly adjustment screw 4 be threaded with bearing bed die steel plate 1, the bottom of adjustment screw 4 contacts the elevation of realizing bearing bed die steel plate 1 and regulates with ground.As optimal way, bearing bed die steel plate 1 below is a hollow structure, is provided with at least three sleeves 5 in bearing bed die steel plate 1 bottom surface, is set with nut 6 in sleeve 5, and adjustment screw 4 is threaded with nut 6.As shown in Figure 2, at this moment, make its rise and fall in sleeve 5 by turn adjustment screw 4, can realize the elevation of bearing bed die steel plate 1 is regulated, during adjusting, the bottom of adjustment screw 4 contacts with ground 9 all the time to form and supports.

In the above-described embodiment, sleeve 5 can be set to a plurality of, and as optimal way, described sleeve 5 has four, is separately positioned on the place, four angles, bottom surface of bearing bed die steel plate 1.Like this, can form an effective support face after adjustment screw 4 installs, simultaneously, four angles, bottom surface that four sleeves 5 are separately positioned on bearing bed die steel plate 1 are located, and can improve the elevation of bearing bed die steel plate 1 and regulate reliability.

In the above-described embodiment, when the lower space of bearing bed die steel plate 1 is narrow and small when being unfavorable for turn adjustment screw 4, can bearing bed die steel plate 1 be provided with through hole 8 over against sleeve 5.Like this, just can extend in the sleeve 5 from this through hole 8 adjustment screw 4 is carried out turn, after adjusting to the right place, these through hole 8 sealings be got final product by instrument.
