Abstract
The utility model belongs to the technical field of supports, and particularly relates to the technical field of leveling supports used in bridge engineering and building engineering. According to the technical scheme, the leveling support comprises a base, an upper base plate and a sliding part, wherein the base is used for being fixed to a lower structure, the upper base plate is used for being fixed to an upper structure, the sliding part is clamped between the base and the upper base plate, and the circumference of the base is provided with at least three leveling mechanisms composed of bottom plates and height adjusting rods fixed to the bottom plates. The support of the structure has the advantages of being high in installation precision and low in labor intensity.
Description
Technical field
The utility model belongs to bearing technical field, relates in particular to the leveling support that a kind of bridge, construction work are used.
Background technology
Bearing is the vitals that connects the infrastructure that the supporters such as superstructure that the bridge beam body support forms and bridge pier form, in time the counter-force of superstructure is delivered to infrastructure, and there is the function of adaptation upper and lower part structure displacement and can distribute horizontal force and adapt to beam-ends corner and be out of shape.
Not only the quality of requirement own is really up to the mark for bearing, and installs also extremely important.Bearing installation requirement is smooth, must not occur partially askew, come to nothing, otherwise in use can destroy too early, to overall structure, cause potential safety hazard.
The structure that forms bearing comprises for the fixing base of infrastructure with for forming with the fixing upper base plate of superstructure and the slide unit being sandwiched between the two.During use (as shown in Figure 1): after bearing 1 is in place, with four jiaos of the bases of wedge 2 wedging bearings, the degree of depth of inserting its bottom by wedge 2 is carried out leveling support, and bottom surface of support saddle is adjusted to design elevation, between bottom surface of support saddle and bearing pad stone, leave 20mm-30mm space, then in pinner end face bearing surrounding, prop up " returning " section mould plate, by the epoxy mortar of working good be filled into preformed hole and and bottom surface of support saddle, while reaching design strength in mortar, remove temporary supporting and template, and the wedge 2 of four jiaos of bearings is taken out, reality is mended in the place that lacks slurry in time.
There is following defect in the installation leveling of this structural bearings: one, while inserting due to wedge 2, pier stud 3 tops are that dry mortar is as levelling grouting agent, roughness is large, wedge 2 moves difficulty and is difficult to hold accurate dimension, make the height of 1 four jiaos of bearings can produce deviation, flatness of support is difficult to reach code requirement; Its two, because pier stud 3 is above the ground level, thereby cause the operating space at its top extremely narrow, and the weight of bearing is very big, so the adjustment of wedge 2 is difficult to be completed by enough personnel's compounding practices, and has great potential safety hazard; Its three, after the grouting of above-mentioned support leveling, wedge 2 exits caused scarce slurry and need to mend slurry and process, loaded down with trivial details, the complex process of not only working, and difficult quality is controlled.To sum up, the bearing of this structure will cause its discontinuity, distortion at the installation initial stage, or has produced initial stress, greatly reduces the life-span of bearing, to engineering, has caused potential safety hazard.
Utility model content
The purpose of this utility model is just to provide the leveling support that a kind of installation accuracy is high, labour intensity is low.
For achieving the above object, the technical solution adopted in the utility model is:
A leveling support, comprises for the fixing base of infrastructure with for forming with the fixing upper base plate of superstructure and the slide unit being sandwiched between the two; In the border of described base, be provided with at least three by base plate and fixingly with it heighten the levelling gear that bar forms.
Form in above-mentioned a kind of leveling support:
---the periphery at described base is provided with outer projection, and described levelling gear is arranged on this outer projection;
---three described outer projections are interconnected to constitute and enclose the shirt rim forming in the periphery of described base.
A kind of height-adjustable supports provided by the utility model compared with prior art has the following advantages: one, because the base border forming bearing is provided with at least three by base plate and heightens the levelling gear that bar forms, by adjustment, heighten the leveling that bar is easy to realize bearing, there is the low feature of installation accuracy labour intensity high, simple to operate and workman; Its two, due to the component part of levelling gear as bearing, complete after leveling without dismounting, therefore can guarantee the permanent balance of bearing, guaranteed bearing overall structure application life; Its three, owing to forming levelling gear, be provided with the base plate that area is larger, therefore can effectively guarantee to make the balance after adjusting.
Accompanying drawing explanation
Fig. 1: be structure and the leveling cross section structure schematic diagram thereof of prior art bearing;
Fig. 2: the leveling support structure and the leveling cross section structure schematic diagram thereof that provide for utility model;
Fig. 3: for forming the structural representation of the base of leveling support;
Fig. 4: for forming the second structural representation of the base of leveling support.
The specific embodiment
Below in conjunction with accompanying drawing, the structure of a kind of leveling support provided by the utility model and use principle thereof are described in further details.
As shown in Figure 2, be a kind of leveling support structure provided by the utility model and leveling cross section structure schematic diagram thereof.The structure that forms this bearing comprises for the fixing base 4 of pier stud 3 with for forming with the fixing upper base plate 6 of superstructure beam body 5 and the slide unit 7 being sandwiched between the two; In the border of above-mentioned base, be provided with three by base plate 8 and the screw rod by the screw on base, formed heighten the levelling gear that bar 9 forms.Its installation process is: the bearing that is provided with levelling gear is placed on pier stud, by screwing the levelness that bar is adjusted bearing of heightening of adjusting three screw rods formation, until after leveling, between base and pier stud coordinate gap in by the epoxy mortar perfusion of working good, wait mortar to reach design strength.Owing to only need screw rod being screwed and can complete height adjustment, therefore when adjusting bearing, installation only need a people to complete, and time saving and energy saving.
In forming the structure of above-mentioned a kind of leveling support:
---very tight owing to forming the combination of 7 of the base of bearing and slide units, be difficult to set out for the space of height-regulating mechanism is set, at least three of the periphery settings at base have outer projection 11(as shown in Figure 3 for this reason), the bar screw rod 9 of heightening that forms levelling gear is installed on outer projection, can makes the adjustment of screw rod convenient;
---in order to improve the mechanical strength that is connected between outer projection and base, be about to above-mentioned three outer projections be interconnected to constitute enclose the shirt rim 10(that forms in the periphery of base as shown in Figure 4).
