Description
Technical Field
The utility model discloses a belong to tunnel preliminary bracing shaped steel bow member processing technology field, concretely relates to a simple and easy fixing device that is arranged in connection steel plate and the shaped steel welding in the bow member processing, this utility model can ensure the relative position of steel sheet sideline and shaped steel in existing connection steel plate and shaped steel welding, has solved the problem that shaped steel steelframe installation work efficiency is low, has apparent practical value.
Background
In the early stage of tunnel construction, a supporting steel arch needs to be prepared, the steel arch usually adopts a steel plate with four bolt holes welded at two ends of the section steel, and then the section steel is connected together through bolts to form the steel arch. When welding a steel plate and a section steel, a pen is generally used for marking the steel plate, the fixed position of the steel plate and the section steel is judged by experience according to the visual position, and then welding is carried out. Therefore, the working efficiency is low, the welding position is deviated frequently, and after welding, the preformed holes of the bolts on the connecting steel plates are staggered when the arch center is connected and installed, and the bolts cannot pass through the connecting steel plates smoothly.
Disclosure of Invention
In order to overcome the problems in the prior art, the utility model provides a simple fixing device in the processing of a section steel arch center, which solves the problem that the relative position is not accurately fixed in the welding of a connecting steel plate and the section steel; the problem that the working efficiency is low in the connection and installation of the profile steel, and the method has the characteristics of low manufacturing cost and simplicity in operation.
In order to achieve the above purpose, the utility model is realized by the following technical scheme:
the simple fixing device in the processing of the profile steel arch comprises a fixing plate 1, a handle 2 and two limiting rods 3, wherein the handle 2 and the limiting rods 3 are respectively fixed on the upper surface and the lower surface of the fixing plate 1, and the handle 2 is obliquely fixed on the fixing plate 1; the fixing plate 1 is provided with a section steel bayonet 4.
Preferably, the handle 2 is inclined 45-80 degrees with respect to the fixing plate 1o。
Preferably, the length of the stop rod 3 is the same as the thickness of the plate steel.
Preferably, the fixing mode of the fixing plate 1, the handle 2 and the limiting rod 3 is welding or integrated connection.
The utility model has the advantages that:
the utility model discloses in the welding process of shaped steel and steel sheet, can pinpoint, the welding position of shaped steel and steel sheet has solved the problem that shaped steel steelframe installation work efficiency is low, and simple structure, convenient operation.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.
As shown in figures 1-6, the simple fixing device for processing the steel arch center comprises a fixing plate 1, a handle 2 and two limiting rods 3, wherein the handle 2 and the limiting rods 3 are respectively fixed on the upper bottom surface and the lower bottom surface of the fixing plate 1, and the handle 2 is inclined 45-80 degrees relative to the fixing plate 1oSo that the handle 2 and the section steel 6 keep a certain distance, and the operation is convenient; the fixing plate 1 is provided with a section steel bayonet 4. The length of gag lever post 3 is unanimous or close with steel sheet 5's thickness to gag lever post 3 can block firmly and do not influence normal welding in to steel sheet 5's the bolt hole and suitably, two gag lever posts 3's diameter and interval and the bolt hole phase-match on the steel sheet 5.
The fixing mode of the fixing plate 1, the handle 2 and the limiting rod 3 is welding or integrated connection.
The utility model discloses a working process:
as shown in fig. 5-6: according to the welding demand, insert two bolt holes of steel sheet 5 with gag lever post 3, with shaped steel 6 along the border and the 4 fixed positions of shaped steel buckle of fixed plate, carry out spot welding with the position of fixed steel sheet 5 and shaped steel 6 behind the rigidity, portable handle 2 takes out the utility model discloses a simple and easy fixing device because handle 3 slopes to be fixed on fixed plate 1, therefore has sufficient space between handle 3 and the shaped steel 6, takes off the utility model discloses the time, can not influenced by shaped steel 6. And then performing full welding to firmly connect the steel plate 5 with the section steel 6.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
