Abstract
The utility model discloses a height adjustable rigid hinge support for bridges. The support comprises an upper support plate (1), a spherical crown lining plate (2) and a lower support plate (3) which are arranged from top to bottom. A spherical sliding plate (4) is arranged between the spherical crown lining plate (2) and the lower support plate (3). The lower support plate (3) consists of a bearing pedestal (5) and an adjusting plate (6), the cross section of both the bearing pedestal (5) and the adjusting plate (6) is wedge-shaped, the bearing pedestal (5) and the adjusting plate (6) are attached by two oblique surfaces, a bearing pedestal adjusting support lug (5a) and an adjusting plate adjusting support lug (6a) are respectively arranged at the common end of the bearing pedestal (5) and the adjusting plate (6), and adjusting screw rods (7) are screwed on the two support lugs. The utility model has the advantages of smart design and low cost. The height adjustable design facilitates arrangement. Meanwhile, the support height is adjusted according to actual conditions so as to ensure that the support bracing always meets design requirements and that the rigid hinge can normally work. The phenomenon that the rigid hinge stress relief is not thorough is avoided.
Description
Technical field
The utility model belongs to the bridge technology field, relates to a kind of adjustable height rigid hinged support that is used for bridge concretely.
Background technology
The good bridge rigidity hinge that continues has adopted the mode of the nested little steel case beam of big steel case beam, and rigidity hinge special carrier (as shown in Figure 3) is set at big or small each bonding surface of steel case beam, the rigidity hinge mainly is made up of big case beam 13, little case beam 14 and bearing 15, forming rigidity hinge to direction by the mode that connects the big case beam 13 in two ends, the left and right sides with little case beam 14 along bridge, its medium and small case beam 14 left ends are fixed in the cavity of the big case beam 13 in the left side, and right-hand member stretches into the inner chamber of the big case beam 13 in the right and supports big case beam 13 by bearing 15.Have relative to the slip and the effect of rotating owing to go up lower support plate in the bearing 15, make the big case beam 13 at two ends, the left and right sides form similar hinged form.Therefore this rigidity hinge has the vertical relative displacement that discharges the girder generation of span centre both sides, vertical, the laterally relative deformation and relatively rotating at constraint girder two ends, and bearing 13 is very crucial parts in cutting with scissors as rigidity, and its support, effectiveness in vibration suppression are particularly important.Cumbersome when mounting and dismounting as relatively large equipment, the height of bearing is advisable greater than the distance between big case beam and the little case beam usually approximately, but because of various errors are difficult to accomplish designing requirement more accurately, so just may cause underbraced or excessive.Simultaneously wherein slide plate can produce that wearing and tearing highly reduce like this, support force reduces meeting influence support effect after long-term the use.
The utility model content
The purpose of this utility model has been to provide a kind of rigid hinged support that is used for bridge that can regulate height of support according to the actual requirements.
The technical solution of the utility model is as follows:
A kind of adjustable height rigid hinged support that is used for bridge, comprise upper bracket plate, spherical crown liner plate and the lower support plate of arranging from top to bottom, be provided with the sphere slide plate between described spherical crown liner plate and the lower support plate, described lower support plate is made up of bearing support and adjustable plate that cross section is wedge shape, fit by two inclined-planes between described bearing support and the adjustable plate, same end at described bearing support and adjustable plate is respectively arranged with bearing support adjusting journal stirrup and adjustable plate adjusting journal stirrup, is rotary with adjusting screw(rod) on two journal stirrups.
When adopting said structure to install, if height of support exists error to be not enough to reach the requirement that design is supported, only need this moment turn joint screw rod pulling adjustable plate that move toward one another is heightened, vice versa.Just can remedy error and install more convenient by regulating.
In the sphere slide plate arranged outside between spherical crown liner plate and lower support plate sealing ring is arranged.
The design of sealing ring can be played and reduce the pollution of external environment dust to sled surface; Influence shuffle effect.
Be rotary with respectively on the adjusting screw(rod) at described bearing support adjusting two ends, the journal stirrup left and right sides and heighten nut and turn down nut.
Make things convenient for the adjusting of adjusting screw(rod), screw and heighten nut and heighten, regulate and finish the back utilization and turn down nut and lock, turn down and lock otherwise then finish.
Beneficial effect: the utility model is skillfully constructed, cost is low, design by the height adjusting has made things convenient for installation, the situation adjustment height of support according to reality meets design requirement all the time with the support that guarantees bearing simultaneously, guarantees rigidity hinge energy operate as normal, avoids rigidity hinge stress release not thorough.

The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 partly cuts open figure for the left view of Fig. 1;
Fig. 3 is the structure principle chart of rigidity hinge in the background technology.
The specific embodiment
Embodiment: as shown in Figure 1, 2: a kind of adjustable height rigid hinged support that is used for bridge, comprise upper bracket plate 1, spherical crown liner plate 2 and the lower support plate 3 of arranging from top to bottom, be provided with sphere slide plate 4 between described spherical crown liner plate 2 and the lower support plate 3, described lower support plate 3 is made up of bearing support 5 and adjustable plate 6 that cross section is wedge shape, fit by two inclined-planes between described bearing support 5 and the adjustable plate 6, same end at described bearing support 5 and adjustable plate 6 is respectively arranged with bearing support adjusting journal stirrup 5a and adjustable plate adjusting journal stirrup 6a, is rotary with adjusting screw(rod) 7 on two journal stirrups.
In sphere slide plate 4 arranged outside between spherical crown liner plate 2 and lower support plate 3 sealing ring 12 is arranged.
Be rotary with respectively on the adjusting screw(rod) 7 at described bearing support adjusting two ends, the journal stirrup 5a left and right sides and heighten nut 7a and turn down nut 7b.
Claims (3)
