Description
Technical Field
The utility model relates to a building apparatus, especially a construction equipment that is used for the bridge to repair and make, specific jacking support for changing bridge beam supports that says so.
Background
As the use time of the urban bridge increases, the rubber support of the urban bridge is prone to damage to different degrees. Therefore, the bridge supports need to be inspected and replaced regularly or irregularly.
At present, the replacement construction of the rubber support of the bridge is mainly carried out by adopting a method of combining a PLC control system with a jack and synchronous jacking equipment, so that the damage to the bridge structure and the traffic interruption can be avoided. However, the top area of part of the bent cap of some bridges is small, and no space is provided for placing an ultrathin jack, which causes great difficulty in construction.
Therefore, a new construction apparatus needs to be designed, which can satisfy the jacking condition of the jack without changing the original bridge structure.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a jacking support for changing bridge beam supports to the problem that meets in bridge beam supports changes construction at present, sound construction, convenient operation can effectively satisfy under the less condition in bent cap top, and the demand of firm installation jack ensures going on smoothly of construction.
The technical scheme of the utility model is that:
a jacking support for replacing a bridge support comprises a support plate I and a support plate II, wherein the support plate I and the support plate II are both straight plate-shaped; the supporting plate I is vertically arranged on the supporting plate II; the support plate II is attached to a concrete bent cap of the bridge and is arranged on the concrete bent cap, and the support plate I is made to be horizontal so that the jack can be placed on the support plate I conveniently; a support plate III is arranged below the support plate I; the supporting plate III is in a trapezoid shape with a large upper part and a small lower part, the upper end of the supporting plate III is connected with the supporting plate I, and the side edge of the supporting plate III is connected with the supporting plate II.
Further, the support plate II is connected with the concrete cover beam through a chemical bolt.
Furthermore, the two support plates III are arranged in parallel.
Further, the device also comprises a rib plate. The ribbed plate is trapezoidal and is arranged above the support plate I, and the adjacent bottom edge and side edge of the ribbed plate are respectively connected with the support plate I and the support plate II; the two ribbed plates are arranged in parallel and are respectively positioned on two sides of the jack.
Further, the device also comprises a backing plate; the backing plate is made of rubber and is arranged between the support plate I and the jack.
The utility model has the advantages that:
the utility model relates to a rationally, simple structure, convenient to use can effectively satisfy under the less condition of bridge bent cap top area, and firm installation jack's demand provides the operation platform who satisfies the atress condition, ensures that the construction goes on smoothly.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in figures 1 to 3.
A jacking bracket for replacing a bridge support comprises a support plate I5, a support plate II6, a support plate III4, a ribbed plate 3 and the like.
The support plate I5 and the support plate II6 are both straight plate-shaped; the supporting plate I5 is vertically installed at the middle part of the supporting plate II 6. The supporting plate II6 is connected with the concrete capping beam of the bridge through a chemical bolt 2, so that the supporting plate II6 is attached to the side wall of the concrete capping beam 1, and the supporting plate I5 is horizontal, so that the jack 7 is placed on the supporting plate I5.
The supporting plate III4 is a trapezoid with a large top and a small bottom, is arranged below the supporting plate I5, is connected with the supporting plate I5 at the upper end, is connected with the supporting plate II6 at the side edge, and can form a powerful support for the supporting plate I5. Preferably, the two support plates III4 are arranged in parallel, so that the support effect is further improved.
The rib plates 3 are right-angled trapezoids with small upper parts and large lower parts, are arranged above the support plate I5, and the adjacent bottom edges and side edges are respectively connected with the support plate I5 and the support plate II 6. The two rib plates 3 are arranged in parallel, the distance between the two rib plates is matched with that of the jack 7, and the two rib plates are respectively positioned on two sides of the jack 7, so that the stability of the jack 7 can be improved.
Further, a backing plate 8 is also included. The pad 8 is made of rubber and is interposed between the support plate I5 and the jack 7 to prevent the jack from being displaced during use.
The support plate I5, the support plate II6 and the support plate III4 are all made of steel plates, are combined into a whole by welding and are fixed with the concrete cover beam by chemical bolts.
The utility model discloses can effectively satisfy under the less condition of bridge bent cap top area, firm installation jack's demand provides the operation platform who satisfies the atress condition, ensures that bridge rubber support's change construction goes on smoothly.
The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
