Description
Technical field
It is especially that a kind of steel truss arched bridge closure section is locked temporarily the utility model is related to a kind of closure section temporary locking device
Determine device.
Background technology
When steel truss arched bridge joins the two sections of a bridge, etc at present, usually welds horse plate or shaped steel carries out temporary locking, technique is asked there are following
Topic；
First, fusion length is longer, limited by steel truss space, overhead welding operation difficulty is big, and subregion can not apply
Weldering, weldquality are not easy to ensure；
Second, the welding procedure time is long, and it is affected by environment big, easily miss best closure opportunity；
Easily agent structure is caused to damage third, weld seam is welded and cut off, the processing such as later stage polishing, application trouble.
Utility model content
Therefore, in order to solve above-mentioned deficiency, the utility model provides a kind of steel truss arched bridge closure section temporary locking dress herein
It sets；Solve the problems, such as that position adjusts and is fixed temporarily when steel truss arched bridge closure.
The utility model is realized in this way constructing a kind of steel truss arched bridge closure section temporary locking device, it is characterised in that：
Temporary locking device locked outside adjusting yoke and case by matching bracket in case, in case steel plate group at；Matching bracket is adopted in its raising middle flask
It is welded with steel plate；Adjusting yoke uses high-strength pull rod in case, and respectively installs a nut in segment bracket both sides；Steel is locked outside case
Plate is formed using case adding rib and connecting plate, and case adding rib and connecting plate are attached by high-strength bolt.
According to steel truss arched bridge closure section temporary locking device described in the utility model, it is characterised in that：Matching in its raising middle flask
Bracket is welded using steel plate, and 3 matching brackets are arranged in single chord member altogether；Adjusting yoke uses the high-strength pull rods of Φ 80mm in case；
The outer locking steel plate of case is formed using 30mm casees adding rib and 20mm connecting plates, and case adding rib and connecting plate pass through 16 Φ
28mm high-strength bolts are attached.
The utility model has the following advantages that：The utility model provides a kind of steel truss arched bridge closure section and faces herein by improving
When locking device, locked outside adjusting yoke and case by matching bracket in case, in case steel plate group at；Matching bracket uses in its raising middle flask
Steel plate welds, and matching bracket is arranged in single chord member altogether；Adjusting yoke uses the high-strength pull rods of Φ 80mm in case, and in segment ox
A nut is respectively installed in leg both sides, to realize pull rod stress needs（Pulling force and pressure）；The outer locking steel plate of case is using outside 30mm casees
Ribbed stiffener and 20mm connecting plates composition, case adding rib and connecting plate are attached by 16 Φ 28mm high-strength bolts.This is specially
After profit is by above-mentioned improvement and implementing, have the following advantages that：（1）Position is adjusted when the utility model solves steel truss arched bridge closure
And the problem of being fixed temporarily；（2）The utility model execute-in-place is convenient, and whole temporary locking devices can be completed in 1 hour
Installment work；（3）The utility model is good by implementing temporary locking effect.
Description of the drawings
Fig. 1-Fig. 2 is the implementation schematic diagram of the utility model steel truss arched bridge closure section temporary locking device；
Fig. 3 is schematic diagram at A in the utility model Fig. 2.
Specific implementation mode
The utility model is described in detail below in conjunction with attached drawing 1- Fig. 3, to the skill in the utility model embodiment
Art scheme is clearly and completely described, it is clear that and the described embodiments are only a part of the embodiments of the utility model, and
