Abstract

The utility model discloses an inverted trapezoidal truss, which comprises a plurality of upright columns and a plurality of inclined columns, wherein the upright columns and the inclined columns are distributed on the left side and the right side of a bridge pier body; the bottom ends of the upright columns and the inclined columns are fixedly arranged on a bearing platform, and the top ends of the upright columns and the inclined columns are fixedly connected with a left longitudinal beam and a right longitudinal beam respectively; the left longitudinal beam and the right longitudinal beam are connected together through a pull rod which penetrates through the pier body; the longitudinal beams are twin I beams; connecting plates are arranged at the tops and the bottoms of two I beams at intervals to form the I beams into an overall member; the bottoms of the upright columns and the inclined columns are connected with an embedded steel plate by using bolts; the pull rod is made of finished threaded steel; a PVC (Polyvinyl Chloride) pipe is embedded in the pier body; the pull rod penetrates into the PVC pipe and the steel plate and then is screwed up by double nuts; and a plurality of supporting rods are welded between the upright columns and the inclined columns. The inverted trapezoidal truss has the advantages of less amount of the used material than that of a full framing support, material saving and reduced construction cost.

Description

Fall parallel chord truss
Technical field
The utility model relates to a kind of structure of falling the parallel chord truss, is the braced structures that is used for the lower cantilever pouring reinforced concrete beam of the bridge engineering pier shaft height in crossing highway, railway or river No. zero piece and a piece construction.
Background technology
Along with the application of technological progress and new material, the reinforced concrete continuous beam of large span is extensively applied in the bridge engineering in crossing highway, railway, river.In the work progress that continuous beam cantilever is built, No. zero piece, a piece are the job platforms of Hanging Basket assembly unit as the girder construction above the pier top.Traditional job practices: operation platform adopts bowl button support or fastener type rack construction; Support is set up on the concrete foundation of cushion cap or interim sclerosis; The number of holders that this construction is used is many, and to soil property around the cushion cap when relatively poor the cure process difficulty big, the construction period is long.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of reinforced concrete continuous beam No. zero piece, a piece construction braced structures are provided, in the hope of simplifying construction technology, economical with materials and cost, shortening No. zero piece, a piece construction period.
The utility model technical solution problem provides following scheme:
A kind of parallel chord truss; Comprise several right cylinders, several oblique column; It is characterized in that: said several right cylinders and several oblique column are distributed in the left and right sides of bridge pier body; The bottom of said several right cylinder and several oblique columns is fixedly mounted on the cushion cap, the top respectively with about two longerons be fixedly connected, said about between two longerons through passing pier shaft pull bar is linked together.
Said longeron is the Two bors d's oeuveres i iron, and at the top/bottom part of two i iron junction plate is set at interval i iron is formed integrated member.
Said right cylinder utilizes bolt to be connected with pre-embedded steel slab with oblique column bottom.
Said pull bar is adopted fining twisted steel, and in pier shaft pre-buried pvc pipe, will penetrate pvc pipe and steel plate to pull bar after the employing double nut tighten.
Many support bars of welding between said right cylinder and the oblique column.
Compare with bowl button (fastener) cribbing, the utility model beneficial effect is embodied in:
1, the utility model structure construction is simple, and right cylinder, oblique column adopt the steel pipe column structure to increase the resistance to torsion of structure.
2, the utility model structure material therefor is few than the full framing consumption, and economical with materials has reduced construction cost.
3, the utility model structure directly be embedded in cushion cap on steel plate be connected, need not cushion cap soil property is on every side hardened.
4, the utility model structure is easy to install, dismantle, and shortening No. zero piece, a piece support are set up the duration.
5, it is assembled that the utility model structure adopts short column, is convenient to a dead lift, and transportation is not limited by motor vehicle length.
6, the setting of the utility model structure pull bar has been reduced vertically forward horizontal movement of support, also avoided simultaneously in the work progress between longeron and beam body bottom, lifting the rear end braced structures.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Referring to accompanying drawing; A kind of parallel chord truss; Comprise several right cylinder 1, several oblique column 2, said several right cylinders 1 and several oblique columns 2 are respectively in the left and right sides of bridge pier body 3, and the bottom of said several right cylinders 1 and several oblique columns 2 is fixedly mounted on the cushion cap 4; The top respectively with about two longerons 5 be fixedly connected, said about between two longerons 5 through passing pier shaft 3 pull bar 6 is linked together.
Said longeron 5 is the Two bors d's oeuveres i iron, and at the top/bottom part of two i iron junction plate 7 is set at interval i iron is formed integrated member.
Said right cylinder 1 utilizes bolt to be connected with pre-buried steel 8 plates with oblique column 2 bottoms.
Said pull bar 6 is adopted fining twisted steels, and in pier shaft 3 pre-buried pvc pipe, will penetrate pvc pipe and steel plate to pull bar 6 after the employing double nut tighten.
Bottom cushion cap 4 is a concrete structure, many support bars 9 of welding between said right cylinder 1 and the oblique column 2.

Claims (6)

1. one kind is fallen parallel chord truss; Comprise several right cylinders, several oblique column; It is characterized in that: said several right cylinders and several oblique column are distributed in the left and right sides of bridge pier body; The bottom of said several right cylinder and several oblique columns is fixedly mounted on the cushion cap, the top respectively with about two longerons be fixedly connected, said about between two longerons through passing pier shaft pull bar is linked together.
2. according to the said parallel chord truss that falls of claim 1, it is characterized in that: said longeron is the Two bors d's oeuveres i iron, and at the top/bottom part of two i iron junction plate is set at interval i iron is formed integrated member.
