Abstract

The invention discloses a bearing frame for bridge construction. The bearing frame in the prior art has the problems that the load endured by a unit area is small, the mounting is complex, the reuse ratio is low and the construction cost is high. The bearing frame for the bridge construction comprises a plurality of horizontal supporting rods, a plurality of inclined supporting rods, a plurality of steel tube vertical columns and a plurality of supporting rod connector sets, wherein each steel tube vertical column is connected with the supporting rod connector sets at adjacent height of steel tube vertical columns along the front, rear, left and right four directions through the inclined supporting rods; only one set of the two sets of supporting rod connectors adjacent to each steel tube vertical column are connected with the inclined supporting rods; the supporting rod connector set on each steel tube vertical column is connected with the supporting rod connector set as high as the adjacent steel tube vertical column through the horizontal supporting rods; and the crossed horizontal supporting rods are provided with bolt holes and are fixed through bolts. The bearing frame for the bridge construction has the advantages of big load endured by the unit area, strong generality, high reuse ratio, more safe and reliable property, and convenience in mounting and dismounting.

Description

A kind of bridge construction bearing frame
Technical field
The invention belongs to building field, relate in particular to a kind of bridge construction bearing frame.
Background technology
It is in the majority that Steel Bridge is generally large span multistage beam.The beam segment base of Steel Bridge originally all is transported to the fabricating yard after produce in factory is finished, and is lifted into the position of designing requirement.But in this process, the beam section of Steel Bridge will be shelved on first on the temporary support with the similar position of permanent buttress, the beam section of Steel Bridge is welded into integral body after in place on the temporary support, then remove temporary support Steel Bridge beam section is dropped on the permanent buttress reposefully.Temporary support plays important system conversion temporary support in this process.Therefore temporary support will satisfy certain technical requirements.Each have their own advantages such as several temporary supports that use in the existing engineering such as single steel pipe frame, gate-type steel pipe frame, welding big steel pipe lattice frame, but all have certain defective as the Steel Bridge temporary support:
1, single steel pipe frame: single steel pipe frame is to be formed by thousands of single steel pipe spellings.Its advantage is applied widely, highly versatile, and repeat usage is high preferably economy.But the work period of its assembling and disassembling is long, and labour intensity is large, and the load that unit area can be born is little, can not use as the temporary support of Steel Bridge.
2, gate-type steel pipe frame: the gate-type steel pipe frame is assembled by sheet gate-type steel pipe.Its advantage of its advantage is applied widely, highly versatile, and repeat usage is high preferably economy, and the work period of assembling and disassembling is shorter.But its labour intensity is large, and the load that installation complexity and unit area can be born is little, should not use as the temporary support of Steel Bridge.
3, welding big steel pipe lattice bracing frame: welding big steel pipe lattice bracing frame is welded into the lattice post by some big steel pipes, angle steel or channel-section steel spelling.Its advantage is that the unit area load that can bear is large, and the temporary support that can be used as Steel Bridge uses.But its assembling and disassembling work outfit is more, the working level trouble, and versatility and the scope of application are wideless, and the low economy of repeat usage is unreasonable, so that construction costs increases.
Summary of the invention
A kind of bridge construction of the present invention comprises many horizontal support bars with bearing frame, many inclined support bars, many steel pipe posts, a plurality of supporting bar connector groups, the adjacent height of steel pipe post on every steel pipe post and the four direction all around the supporting bar connector group be connected by inclined support bar, only have one group to be connected with inclined support bar in the adjacent two groups of supporting bar connectors of each root steel pipe post, supporting bar connector group on every steel pipe post is connected by horizontal support bar with the supporting bar connector group of adjacent steel pipe post equal altitudes, have bolt hole on the horizontal support bar that wherein intersects, and be bolted.
Described horizontal support bar is made by channel-section steel, and two ends have a plurality of bolts hole;
Described inclined support bar comprises the body of rod and body of rod joint, and rod body material is channel-section steel, and body of rod joint one end is fixedly connected on the body of rod, and the other end drift angle of body of rod joint is a right angle and has a plurality of bolts hole;
The two ends of described steel pipe post all are provided with reinforcing rib, and steel pipe post connects by flange on the vertical direction, and the bottom of steel pipe post is provided with adjusting post;
Described supporting bar connector group is comprised of eight supporting bar connectors, and adjacent two supporting bar connectors are orthogonal.Supporting bar connector is made by the steel plate that has a plurality of bolts hole.
Beneficial effect: the load that unit area of the present invention can be born is large, can satisfy again applied widely, highly versatile, repeat usage is high, and higher economy is arranged, safety and reliability, and the work of assembling and disassembling is convenient, fast.
