Abstract
The utility model discloses a welding positioner for a connecting steel plate of a steel arc truss. The key technology of the utility model is that the welding positioner comprises I-shaped steel, a handle arranged at the waist part of the I-shaped steel and positioning round steels which are symmetrically arranged in front of two legs of the I-shaped steel. The welding positioner has a simple structure, is accurate and quick for positioning during welding and is beneficial to shortening the construction period.
Description
Technical field
The utility model relates to the frock of using in the preliminary bracing construction of a kind of tunnel, and especially a kind of steel bow member connects the steel plate welded retainer.
Background technology
In recent years, China's infrastructure Large scale construction, big section, large span Extra Long Tunnel Construction engineering get more and more.In tunnel initial stage construction mainly based on the bow member supporting.Because excavated section is big, single Pin I-steel props up to be needed I-steel is divided into plurality of sections immediately, adopts the connection steel plate to connect so that construction with bolt again.This just needs and will weld together through connection steel plate and the I-steel after the boring, needing the special messenger during welding at present is responsible for positioning when welding, owing to there is not special orientation tool, not only process velocity is slow, often occur also that bolt does not connect, the bow member axis is not collinear, bow member circle along etc. phenomenon, influenced construction speed.
The utility model content
The technical problems to be solved in the utility model provides a kind of steel bow member and connects the steel plate welded retainer, and it is simple in structure, accurate positioning is quick, help saving the duration.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of steel bow member connects steel plate welded retainer, the location round steel that it comprises I-steel, is located at the handle of I-steel waist and is symmetrically set in I-steel two shank fronts.
Preferably, above-mentioned I-steel and handle welding, above-mentioned I-steel and location round steel welding.
Adopt the beneficial effect that technique scheme produced to be: when connecting steel plate, to hold handle the location round steel on this welded retainer is inserted in the hole that connects on the steel plate, be put in then to weld and get final product with I-steel section to be welded with I-steel to be welded welding; Accurate positioning is quick after adopting the utility model, and simple to operate easily, help saving the duration.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 connects steel plate and bow member connection diagram;
Wherein, 1, location round steel; 2, handle; 3, I-steel; 4, hole; 5, I-steel to be welded; 6, connect steel plate.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to accompanying drawing 1 and accompanying drawing 2, the location round steel 1 that the utility model comprises I-steel 3, is located at the handle 2 of I-steel 3 waists and is symmetrically set in 3 liang of shank fronts of I-steel.Described I-steel 3 and handle 2 welding, described I- steel 3 and 1 welding of location round steel.Of the present utility model drawing materials conveniently, and processing and fabricating is convenient.
Referring to accompanying drawing 3, when specifically using, I-steel 3 selects for use discarded I-shaped steel to get final product, and its model is selected for use than the 5 little models of the I-steel to be welded in the steel bow member, is convenient to the location.Location round steel 1 is inserted in the hole 4 that connects steel plate 6, will connect steel plate 6 then and be put in I-steel 5 sections to be welded location and weld and get final product.In the construction,, design the welded retainer of different model accordingly according to the size of steel bow member.
Adopt the utility model, can improve the accuracy and the working (machining) efficiency of steel bow member processing greatly, can reduce the input of bow member processing manpower simultaneously, thereby reduce cost.
