After the new century, the infrastructure construction of China is continuously improved, and the supporting force for the development of the economic society is obviously improved. I-shaped steel, shaped steel and other materials play irreplaceable effects in the infrastructure construction process, and the I-shaped steel is generally used for scenes such as preliminary bracing, bridge support, factory building crossbeam of tunnel excavation. In the work progress, I-steel's live length can be adjusted because of the construction conditions, can't adopt the steel bar connection because of the particularity of its structure, and the connection method who usually adopts is: and welding steel base plates on the ends of the I-shaped steel, wherein the steel base plates are provided with connecting holes, and when the I-shaped steel is connected, aligning the connecting holes of the two I-shaped steel end steel base plates and connecting and fixing the two I-shaped steel end steel base plates by using bolts.
When the steel backing plate is welded on the end of the I-shaped steel, whether the welding position of the steel backing plate is vertical or centered affects the connection quality of the straight drop of the I-shaped steel; the welding of the steel base plates is not perpendicular to the I-shaped steel, so that the steel base plates of the two I-shaped steels cannot be tightly attached and cannot be tightly connected; the steel backing plate welding is not in the middle in the I-steel end, can lead to two steel backing plates on the preformed hole can't align, makes the bolt be difficult to fixed, and then can lead to the I-steel to connect the position deviation that appears, influences the holistic quality of connection structure, increases the uncontrollable safety risk after the construction.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems, and provides a welding clamp for the I-shaped steel and the steel backing plate, which ensures that the steel backing plate is perpendicular to the I-shaped steel and centered with respect to the I-shaped steel after welding.
Utility model solves the problem, the technical scheme who adopts is:
the utility model provides a welding fixture of I-steel and steel backing plate, is including placing the end location steel sheet on the I-steel web tip, and end location steel sheet one side is equipped with the positioning steel bar with steel backing plate connecting hole adaptation, and the opposite side is connected with the counter weight steel sheet.
Compared with the prior art, the utility model adopting the technical scheme has the outstanding characteristics that:
the connecting hole of the steel gasket penetrates through the positioning steel bar and is tightly attached to the end head of the I-shaped steel, and the end head of the I-shaped steel is positioned in the center of the steel base plate. The utility model has the advantages of simple structure, convenient manufacture, accurate positioning, reutilization and stronger popularization.
Preferably, the further technical scheme of the utility model is as follows:
the end positioning steel plate and the counterweight steel plate are connected through a connecting rib, and the length of the connecting rib is 30-50 cm; the device is convenient to transport and has wider application range.
The mass of the counterweight steel plate is greater than that of the steel backing plate; and the steel base plate is ensured to be stably suspended on the positioning steel bar.
The width of the end positioning steel plate is 4-6mm shorter than the distance between two flanges of the I-shaped steel; not only be convenient for place this device between the I-steel edge of a wing, and be convenient for this device and remove in the I-steel, avoid the gap too big between device and the I-steel edge of a wing simultaneously, the device is placed unstably.
At least two positioning steel bars are arranged, and the length of each positioning steel bar is 1.5-2.5 times of the thickness of the steel base plate; the steel base plate can be stably connected to the positioning steel bars.

Detailed Description
The utility model will be further illustrated by the following examples, which are intended only for a better understanding of the present invention and therefore do not limit the scope of the utility model.
As shown in fig. 1 to 3, the fixture for welding the i-steel and the steel backing plate comprises an end positioning steel plate 1 placed on the end part of a web plate of the i-steel. And two positioning steel bars 2 matched with the connecting holes of the steel base plate 5 are welded on one side of the end positioning steel plate 1. And the other side of the end positioning steel plate 1 is welded with a connecting rib 3, and the length of the connecting rib is 30-50 cm. The tail end of the connecting rib 3 is welded with a counterweight steel plate 4. The quality of counter weight steel sheet 4 is greater than the quality of steel backing plate 5 to when guaranteeing that steel backing plate 5 encorbelments on positioning reinforcement 2, the fixture is whole can maintain stable state, can not take place the displacement and deflect. Wherein, the connecting hole of the steel backing plate 5 is perforated according to the requirement.
Furthermore, the fixture can be conveniently placed between flanges of the I-steel 6, and can move in the I-steel 6. The shape of the end positioning steel plate 1 is designed to be matched with the shape of the single-side section of the I-shaped steel 6. The width of the end positioning steel plate 1 is 5mm shorter than the distance between two flanges of the I-shaped steel 6. It should be noted that the gap between the device and the flange of the i-steel 6 is not easy to be too large, otherwise the stability of the device in use is affected.
Furthermore, 2-4 positioning steel bars are arranged. The length of the positioning steel bar is 2 times of the thickness of the steel backing plate.
The manufacturing engineering of the fixture is as follows: an end positioning steel plate 1 is firstly processed, and the end positioning steel plate 1 is formed by cutting a steel plate. Then, intercepting the reinforcing steel bar with proper length, manufacturing the positioning reinforcing steel bar 2 outside the end positioning steel plate 1, and welding the end positioning reinforcing steel bar 2 outside the end positioning steel plate 1. Then, the steel plate is cut to process a counter weight steel plate 4 satisfying the mass counter weight. Meanwhile, three reinforcing steel bars with the length of 30-50cm are cut out to serve as connecting ribs 3. And welding a counterweight steel plate 4 at the rear side of the end positioning steel plate 1 through a connecting rib 3. After the assembly welding is completed, the welding operation of the I-shaped steel 6 and the steel backing plate 5 can be performed. When in use, the connecting hole of the steel backing plate 5 penetrates through the outer positioning steel bar 2. The steel backing plate 5 is tightly attached to the I-shaped steel 6, and the end of the I-shaped steel 6 is positioned in the center of the steel backing plate 5. And then welding the I-shaped steel 6 and the steel backing plate 5.
The utility model is suitable for welding the I-steel ends of primary support I-steel for tunnel excavation, bridge supports, workshop beams and the like with the steel backing plate.
