Description

Bridge engineering Coping Construction bracket

Technical field

The utility model relates to a kind of bridge engineering Coping Construction bracket.

Background technology

In bridge engineering, Coping Construction bracket majority adopts hood type bracket or full hall formula bracket, hood type bracket utilizes to install anchor ear at the suitable position of bridge pier, and make it to be clamped on bridge pier, produce maximum stiction, overcome the weight of temporory structure and bent cap, the safety of this hood type bracket is bad, easily glides; Full hall formula bracket is spliced with a large amount of steel pipe, and the engineering time is long, and cost is high, is only suitable for the Coping Construction of particular/special requirement, as tunnel etc.

Utility model content

For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of bridge engineering Coping Construction bracket, to make up poor stability, engineering time length, high in cost of production defect that existing bracket exists.

In order to solve the problems of the technologies described above, the utility model have employed following technical scheme:

A kind of bridge engineering Coping Construction bracketcomprise several truss, described truss comprises upper and lower two main chords be parallel to each other and is arranged on the web member coupled together between upper and lower two main chords and by upper and lower two main chords, main chord and web member are all the square steel being connect welding by two channel-section steels and formed, and couple together between the main chord of left and right two adjacent truss with splicing construction.

Preferably, described splicing construction comprises subrack and latch, and described subrack is arranged between two main chords of left and right two adjacent truss, and the two ends of subrack are inserted in left and right two main chords respectively; The splicing position of left and right two main chords all has the pin-and-hole perpendicular to its length direction, in the pin-and-hole of left and right two main chords, insert latch respectively, and latch is locked with pin after running through main chord; The two ends of subrack have the perforation corresponding with pin-and-hole, and the latch on left and right two main chords runs through the two ends of subrack respectively.

Preferably, arrange stiffener in the both sides at main chord splicing position, described stiffener has the perforation corresponding with pin-and-hole, and latch runs through the stiffener of both sides and is locked with the stiffener of pin by both sides.

The beneficial effects of the utility model are:

When constructing, first in the perforation of bridge column, reinforcing bar is inserted, and then bracket is set up on reinforcing bar, workman can stand directly on operation on platform bracket, compared with hood type bracket, bracket of the present utility model is set up on the reinforcing bar of bridge pier, be less likely to occur glide, worker stands on bracket during operation security performance greatly improve; Compared with full hall formula bracket, bracket of the present utility model is spliced by several truss, couples together during splicing with the main chord of splicing construction by adjacent truss, splice simpler, splicing number of times is few, substantially reduces the engineering time, reduces construction cost; Simultaneously because bracket of the present utility model utilizes channel-section steel to process, add and only need man-hour to carry out blanking by size, and then carry out welding, should draw materials and process, with low cost, practicality is high, is easy to promote.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

See Fig. 1-8c, bridge engineering Coping Construction bracket of the present utility model is spliced by some sections of truss, the quantity of truss depends on the length of bridge, truss comprises upper and lower two main chords be parallel to each other 11 and is arranged on the web member coupled together between upper and lower two main chords 11 and by upper and lower two main chords, web member comprises vertical web member 12 and inclination web member 13, and main chord 11, vertical web member 12 and inclination web member 13 are all the square steel being connect welding by two channel-section steels and formed.

The bridge engineering Coping Construction bracket of the present embodiment is spliced mutually by truss the first from left section 1, truss the second from left section 2, two section 3, the truss right side and right one section 4 of truss, wherein, couple together with splicing construction between the main chord 11 of left and right two adjacent truss, splicing construction comprises subrack 5 and latch 6, subrack 5 is arranged between two main chords 11 of left and right two adjacent truss, and the two ends of subrack 5 are inserted in left and right two main chords 11 respectively; The splicing position of left and right two main chords 11 all has the pin-and-hole perpendicular to its length direction, inserts latch 6 respectively, insert pin lock dead after latch 6 runs through main chord 11 in the pin-and-hole of latch 6 front end in the pin-and-hole of left and right two main chords 11; The two ends of subrack 5 have the perforation corresponding with pin-and-hole, latch 6 on left and right two main chords runs through the two ends of subrack 5 respectively, because the two ends of subrack 5 are locked on left and right two main chords 11 by latch 6, therefore left and right two main chords 11 are coupled together by subrack 5.

In order to increase bonding strength, the both sides can also splicing position at main chord 11 arrange stiffener 14, stiffener 14 have the perforation corresponding with pin-and-hole, latch 6 inserts pin after running through the stiffener 14 of both sides in the pin-and-hole of latch 6 front end, is locked at by stiffener 14 on the two sides of main chord 11.

Finally it should be noted that, above embodiment is only in order to illustrate the technical solution of the utility model but not restriction technologies scheme, although applicant has been described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present utility model.
