Description
Technical field
The present invention relates to bridge building operations field, and in particular to a kind of attachment structure applied to bridge temporary project.
Background technology
Architectural engineering it is outer it is interim set up during, it usually needs integrated deck plate, at present conventional construction floorings
Built using 12 I-steel, and can staggeredly set up 25 I-steel in the lower floor of 12 I-steel and interlock as support, usual levels
The fixed form for the I-steel put uses electric welding, is securely joined together it, and in actual use, floorings are taken
If being work high above the ground, made troubles to electrical welding operation.
In order to solve the above-mentioned technical problem, such as Patent No. CN201610911243.X, (application publication number is
CN106436567A Chinese patent application)《A kind of trestle bridge floor》, including I-steel, keel, pad, wedge, connecting plate,
Bolt, nut, the edge of a wing, keel are fixed on the outer side wing edge of I-steel using bolt, nut, pad, between two blocks of I-steel
It is fixedly connected, is equally fixedly connected between connecting plate and I-steel using bolt, nut, pad, although equally using connecting plate
The connection of I-steel is realized, still, bolt needs to sequentially pass through connecting plate, the edge of a wing of I-steel, wedge and passes through nut
Locking, during long-term use, bolt is easily corroded, and is needed it is difficult to will be dismantled between I-steel, during dismounting
I-steel could be split by way of cutting, can so cause the damage of I-steel so that I-steel can not circulate
Using and cause waste of material, the utilization rate of material is low.
And for example Patent No. CN201220738755.8 (Authorization Notice No. CN202969902U) Chinese utility model
Patent《Be connected device between the pre-buried I-steel of outrigger》, the device that is connected includes the steel plate and screw-thread steel of edge wing fastener,
Screw-thread steel is placed on the centre position of the steel plate of edge wing fastener vertically, and the two connection forms inverted " t " type component, and it also has including interior
The steel plate and nut of through hole, the screw-thread steel on edge wing fastener have the steel plate of through hole, nut to be sequentially connected with interior, and nut is located at steel plate
Top, although the connection between realizing the I-steel of interlaced arrangement, connection is insecure, during long-term use,
Easily loosen, potential safety hazard be present.
Therefore, it is necessary to be improved further the attachment structure existing I-steel.
The content of the invention
The technical problem to be solved by the invention for the present situation of prior art is to provide it is a kind of be connected firmly be applied to
The attachment structure of bridge temporary project.
Technical scheme is used by the present invention solves above-mentioned technical problem：A kind of connection applied to bridge temporary project
Structure, it is characterised in that：Include upper connector, first time connector and second time connector, the upper connector passes through
