Description
Technical Field
The utility model belongs to the technical field of bridge construction equipment, a device is changed to bridge beam supports is related to.
Background
The bridge support is an important structural component for connecting an upper structure and a lower structure of a bridge, is positioned between the bridge and the pad stone, can reliably transfer load and deformation borne by the upper structure of the bridge to the lower structure of the bridge, and is an important force transfer device of the bridge. Because the service life of the support is 10-20 years, the support needs to be replaced regularly, the support needs to be replaced by synchronously jacking the beam body by using a jack, and in some bridges designed in the previous years, the height of the support cushion is very low, so that the jack cannot be placed, and therefore a temporary support replacement device needs to be designed.
Disclosure of Invention
The utility model provides a to above-mentioned problem, a device is changed to bridge beam supports is provided, and this change device can carry out reliable and stable support change operation to the bridge.
According to the technical scheme of the utility model: a bridge support replacing device comprises an upright post and a cross beam supported on the top surface of the upright post, wherein the cross beam is integrally connected with a main beam; the method is characterized in that: the two sides of the surface of the upper part of the upright post are respectively fastened with a supporting piece, the top surface of each supporting piece is respectively provided with a lower cushion block, a jack is supported on the lower cushion block, and the jacking end of the jack is supported on the bottom surface of the cross beam.
As a further improvement of the present invention, the support member includes a vertical surface, a horizontal surface and an inclined strut supported between the vertical surface and the horizontal surface, wherein the vertical surface is connected to the column by a screw fastening.
As a further improvement of the utility model, the both sides corresponding to the bracing on the support piece are respectively through screw and stand fastening connection.
As a further improvement of the present invention, the lower cushion block upper surface is provided with an upper cushion block to support the jacked beam.
The technical effects of the utility model reside in that: the product of the utility model has reasonable and ingenious structure, can realize the replacement of the support which is directly arranged on the upright post of the bridge during operation, and can manufacture the temporary supporting device of the utility model at the periphery of the upright post; when the jack is used specifically, the jack needs to be tested through a load test and can bear corresponding support reaction force.
Drawings

Fig. 2 is a sectional view taken along line a-a of fig. 1.
Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings.
In the figures 1 and 2, the device comprises a vertical column 1, a support 2, a vertical surface 2-1, a horizontal surface 2-2, an inclined strut 2-3, a lower cushion block 3, a jack 4, a cross beam 5, a main beam 6, an upper cushion block 7 and the like.
As shown in fig. 1 and 2, the utility model relates to a bridge bearing replacing device, which comprises a vertical column 1 and a beam 5 supported on the top surface of the vertical column 1, wherein the beam 5 is integrally connected with a main beam 6; the supporting pieces 2 are fastened on two sides of the upper surface of the upright post 1 respectively, a lower cushion block 3 is arranged on the top surface of each supporting piece 2, a jack 4 is supported on each lower cushion block 3, and the jacking end of each jack 4 is supported on the bottom surface of the cross beam 5.
The supporting piece 2 comprises a vertical surface 2-1, a horizontal surface 2-2 and an inclined strut 2-3 supported between the vertical surface 2-1 and the horizontal surface 2-2, wherein the vertical surface 2-1 is fixedly connected to the upright post 1 through a screw.
Two sides of the support member 2 corresponding to the inclined struts 2-3 are respectively fastened and connected with the upright post 1 through screws.
The upper surface of the lower cushion block 3 is provided with an upper cushion block 7 for supporting the jacked beam 5.
The utility model discloses cushion 3 and support piece 2 in the product all adopt machining, and the error is within 0.2mm, and jack 4 needs should be able to bear corresponding counter-force through the load test inspection.
The size of the support 2 (determined according to the size of the jack 4) should be determined firstly before the support 2 is manufactured by blanking, meanwhile, the position of the support 2 is determined according to the jacking space requirement, and the blanking is manufactured after the information is determined. After the synchronous jacking construction is finished, the supporting piece 2 is detached for the turnover use of the subsequent synchronous jacking of the pier.
Taking 100 ton jack 4 as an example, the supporting member 2 is suggested to be made of a Q2345 steel plate with the thickness of 30mm, three stiffening inclined struts 2-3 with the thickness of 30mm, and each supporting member 2 is connected with the pier body by 6M 24 high-strength anchor bolts with the thickness of 8.8 grades. During construction, the size of the steel pipe can be adjusted according to actual conditions on site, and construction safety must be ensured. The size of the steel gasket is set according to the actual situation, and the safety is ensured. Before construction, the arrangement condition of each pier and the support is rechecked pier by pier, and the jacking support bracket and the corresponding construction scheme are determined according to the actual size.
