Abstract
The utility model relates to a novel M-type expansion joint which comprises boundary beams, sealing strip grooves, fixing plates, reinforcing ribs, a strengthening shaft and fixing nuts. The novel M-type expansion joint is characterized in that the cross section of each boundary beam is in an M shape, the sealing strip grooves are formed in the upper inner sides of the boundary beams, sealing strips are arranged in the sealing strip grooves, the left boundary beam and the right boundary beam are symmetrically arranged, the fixing plates are arranged on the outer walls of the lower sides of the boundary beams, and the reinforcing ribs are welded to the fixing plates respectively. The M-type expansion joint is characterized in that the strengthening shaft is arranged between the left boundary beam and the right boundary beam, the left boundary beam and the right boundary beam are connected together through the strengthening shaft, the strengthening shaft is connected with the boundary beams through the fixing nuts, and the distance between the left boundary beam and the right boundary beam are adjusted by screwing the fixing nuts. The novel M-type expansion has the advantages that the strengthening shaft is arranged between the two boundary beams, the strengthening shaft is convenient to replace, the distance between the boundary beams can be adjusted through the fixing nuts, the borne gravity of the strengthening shaft is large, the structure is simple, the manufacturing cost is low, and the service life long.
Description
Technical field
The utility model relates to a kind of novel M type shrinkage joint.
Background technology
At present, construction along with highway, railroad bridge, people have developed various bridge expanssion joints, they are comprised of the fixedly welding plate of side bar, seal strip groove and connection side bar, like this when the bridge load-carrying is used greatly or for a long time, the fixedly welding plate that connects between the side bar is broken easily, makes bridge expanssion joint impaired, and application life is short.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of novel M type shrinkage joint is provided, utility model solves the technical scheme that its technical problem adopts: structure of the present utility model comprises side bar, seal strip groove, fixed head, reinforcing rib, reinforcing axle, hold-down nut, the cross section that it is characterized in that side bar is M shape, the inboard is provided with seal strip groove on the side bar, weather strip is set in the seal strip groove, about two symmetrical settings of side bar, be provided with fixed head on the downside outer wall of side bar, be welded with reinforcing rib on each fixed head.
Described novel M type shrinkage joint, be provided with the reinforcing axle between two side bars about it is characterized in that, the right and left beam links together by reinforcing axle, reinforces axle and is connected with side bar by hold-down nut, regulates distance between the right and left beam by screwing hold-down nut.
The design feature at this shrinkage joint is to arrange one to reinforce axle between two adjacent side bars, reinforcing axle is connected with side bar by nut, be convenient for changing, like this when carrying gravity is larger, reinforce axle and can bear the pressure that disperses the external world to bring, thereby reach the purpose that improves the shrinkage joint life-span, and can regulate two distances between the side bar by the hold-down nut of reinforcing on the axle.
The beneficial effects of the utility model are, the utility model increases by one and reinforces axle between two side bars, both are convenient for changing, and can regulate spacing between the side bar by hold-down nut again, and it is large, simple in structure, cheap to reinforce the bearing carrying force, long service life.
Description of drawings
Fig. 1: the utility model embodiment section structure schematic diagram;
Fig. 2: the utility model embodiment side-looking structural representation;
Among the figure: side bar 1, seal strip groove 2, fixed head 3, reinforcing rib 4, reinforcing axle 5, hold-down nut 6.
The specific embodiment
With reference to description of drawings the utility model is done following concrete detailed description; As shown in drawings, structure of the present utility model comprises side bar 1, seal strip groove 2, fixed head 3, reinforcing rib 4, reinforces axle 5, hold-down nut 6, the cross section that it is characterized in that side bar 1 is M shape, the inboard is provided with seal strip groove 2 on the side bar 1, the seal strip groove 2 interior weather strips that arrange, about two side bar 1 symmetrical settings, be provided with fixed head 3 on the downside outer wall of side bar 1, be welded with reinforcing rib 4 on each fixed head 3.
Described novel M type shrinkage joint, be provided with reinforcing axle 5 between two side bars 1 about it is characterized in that, the right and left beam 1 links together by reinforcing axle 5, reinforces axle 5 and is connected with side bar 1 by hold-down nut 6, regulates distance between the right and left beam 1 by screwing hold-down nut 6.
Embodiment recited above is described preferred embodiment of the present utility model; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design concept; common engineers and technicians make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
