Description

A kind of tool fixture for steel arch-shelf welding steel

Technical field

The utility model relates to welding for steel structure technical fields, and in particular to a kind of tooling for steel arch-shelf welding steel Jig.

Background technique

East -Tianshan super long tunnel import is located at Xinjiang pine tree pool skifield west side, and the main hole overall length 10133m(conversion in tunnel is single Hole), the main hole in tunnel uses separate type two-way four-lane, needs to weld the larger workload of arch, welding during constructing tunnel It is easy to appear junction steel plate in the process to weld not just, junction steel plate and I-steel be not in a center line, junction steel plate and steel arch A series of problems, such as frame welding is left-right asymmetry, causes repeatedly to do over again, processing efficiency is not high, and quality is also difficult to ensure.

Utility model content

To solve drawbacks described above, the purpose of the utility model is to provide a kind of toolings for steel arch-shelf welding steel to control Tool, structure is simple, and design rationally, can effectively solve the not conllinear and asymmetry problem occurred when steel plate welding, improve steel plate The processing efficiency of welding ensure that the welding quality of steel plate.

In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of work for steel arch-shelf welding steel Filling jig, the first angle brace vertically and symmetrically placed including two is separated with certain distance between two first angle braces, and two described first At the top of angle brace by be welded with second angle brace and link together, the weldering being made of two first angle braces and second angle brace Fitting side is plane, is welded with third angle brace in the side of the plane, an angle arm and the plane for the third angle brace is total Face, another angle arm after welding is towards the front of the plane.

Preferably, when an angle arm of the third angle brace is with the co-planar, it is welded on any of the weldment Side.

Each end after two first angle braces are welded with second angle brace is aligned.

Second angle brace top is equipped with handle, the taking-up after facilitating welding.

When the utility model is used, two first angle braces 1 top weld the second angle brace when, two first angle braces Spacing distance in welding can match with the plate arm width of I-steel, after welding, when I-steel end needs to weld When connecing steel plate, the utility model is inserted into one end outside the I-steel, second angle brace bottom surface contacts the plate arm of I-steel, The end face of plane and I-steel maintains an equal level, and surface of steel plate is placed on I-steel end at this time, so that surface of steel plate and plane is maintained an equal level, i.e., To agree with completely with I-steel end face, another angle arm of steel plate end thereof contacts third angle brace is positioned by the angle arm, positioning Start the end that steel plate is welded on to I-steel afterwards, ensure that steel plate and I-steel are welded on same center line, welding finishes Later, tooling is taken out.

Compared with prior art, the utility model structure is simple, and design rationally, occurs when can effectively solve steel plate welding Not conllinear and asymmetry problem improves the processing efficiency of steel plate welding, ensure that the welding quality of steel plate.

Detailed description of the invention

Below according to accompanying drawings and embodiments, the structure and features of the utility model is further described.

Fig. 1 is the structural schematic diagram of the utility model.

Fig. 2 is that the utility model uses schematic diagram in I-steel one end welding steel.

In attached drawing 1 and Fig. 2,1. first angle braces, 2. second angle braces, 3. third angle braces, 4. handles, 5. I-steel, 6. planes, 7. steel plate.

Specific embodiment

It is an embodiment of the present invention referring to attached drawing 1 and Fig. 2.

A kind of tool fixture for steel arch-shelf welding steel, the first angle brace 1 vertically and symmetrically placed including two, two institutes State and be separated with certain distance between the first angle brace 1, two first angle braces, 1 tops by be welded with second angle brace 2 and link together, It is plane 6 by the weldment side that two first angle braces 1 and second angle brace 2 form, is welded in the side of the plane 6 Third angle brace 3, an angle arm of the third angle brace 3 is coplanar with the plane 6, and another angle arm after welding is towards the plane 6 Front.

Preferably, when an angle arm of the third angle brace 3 is coplanar with the plane 6, it is welded on appointing for the weldment Side.

Each end after two first angle braces 1 are welded with second angle brace 2 is aligned.

Second angle brace, 2 top is equipped with handle 4, the taking-up after facilitating welding.

When the utility model is used, two first angle braces 1 are when the second angle brace 2 is welded at top, two described first jiao Spacing distance of the support 1 in welding can match with the plate arm width of I-steel 5, after welding, when 5 end of I-steel needs When wanting welding steel 7, the utility model is inserted into one end outside the I-steel, 2 bottom surface of the second angle brace contacts I-steel Plate arm, the end face of plane 6 and I-steel 5 maintains an equal level, and surface of steel plate is placed on 5 end of I-steel at this time, make surface of steel plate with Plane 6 maintains an equal level, and as agrees with completely with I-steel end face, another angle arm of 7 end thereof contacts third angle brace 3 of steel plate passes through the angle Arm is positioned, and starts the end that steel plate is welded on to I-steel after positioning, ensure that steel plate and I-steel are welded in same On heart line, after welding finishes, tooling is taken out.

Described above is only the preferred embodiment of the utility model, and above-mentioned specific embodiment is not to the utility model Limitation, retouching, modification or the equivalent replacement that all those skilled in the art are made as described above belong to this reality With novel protection scope.
