The utility model provides a welding positioning fixture for tunnel arch centering and connecting steel plate, as shown in figure 1 and figure 2, the positioning fixture comprises three plates 1 and three rods 2, wherein the three plates 1 are connected to form a U-shaped part, and the opening of the U-shaped part can be covered on the I-shaped steel; the member bar 2 is provided with at least two, and at least two member bar 2 are connected in the open-ended one end of U type spare, and member bar 2 can with the bolt hole cooperation location on the connecting steel plate.
The utility model discloses a welding position fixture for tunnel bow member and connecting steel plate connects formation U type positioning fixture through three plate 1, open-ended one end is equipped with two at least members 2, during the use, the opening cover of U type positioning fixture is established on the I-steel, open-ended one end is only supported on connecting steel plate and two at least members 2 can wear to establish the corresponding bolt hole on the connecting steel plate respectively, the accurate positioning of the I-steel and connecting steel plate of being convenient for, thereby realize the accurate connection between I-steel and the connecting steel plate, improve welding quality.
It should explain that, the relation of connection between I-steel and the connecting steel plate is, connecting steel plate welding is on the terminal surface of I-steel to will guarantee the straightness that hangs down between I-steel major axis and the face of connecting steel plate, the utility model provides a location fixture is exactly for fixing a position the perpendicular angle between I-steel and the connecting steel plate. When the rod piece 2 penetrates through the connecting steel plate and fixes the connecting steel plate, the connecting steel plate just can abut against one end face of the U-shaped piece, so that the vertical welding of the I-shaped steel and the connecting steel plate can be realized, and the welding quality is improved.
Optionally, the plate 1 comprises a first plate 11, a second plate 12 and a third plate 13, and the second plate 12 and the third plate 13 are arranged at an interval on the same side of the first plate 11 and parallel to each other, and perpendicular to the first plate 11. As shown in fig. 1, the second plate 12 and the third plate 13 are vertically disposed on the first plate 11 to form a U-shaped member, and according to practical situations, the opening of the U-shaped member, i.e., the vertical distance between the second plate 12 and the third plate 13, is greater than the width of the i-steel to be welded, and the distance between the inner sides of the second plate 12 and the third plate 13 is generally set to be just equal to the width of the outer side of the i-steel, so that the U-shaped member can be positioned relative to the i-steel in the cross-sectional direction, and displacement during welding can be prevented.
Alternatively, the second plate 12 and the third plate 13 each have a width smaller than the width of the first plate 11, and the first plate 11, the second plate 12 and the third plate 13 are aligned at the end of the opening opposite the bar 2. It can be understood that the end face of the first plate 13 on one side of the rod 2 is abutted against the connecting steel plate, and the first plate 11, the second plate 12 and the third plate 13 on the other side are aligned and connected at the port or the end face of the opening of the U-shaped part, so that the second plate 12 and the third plate 13 on one side of the rod 2 are ensured not to be in contact with the connecting steel plate, the position to be welded on the connecting steel plate is fully exposed, and the shielding effect cannot be generated.
Further, the first plate 11, the second plate 12 and the third plate 13 are all made of steel plates, so that the strength is high, the deformation is not easy to occur, and the construction site is easy to obtain.
Preferably, the first plate 11 is welded to the second plate 12, and the first plate 11 is welded to the third plate 13. The welding seam is along the width direction of second plate 12 and third plate 13, and both sides all weld, increase welding strength and stability.
Optionally, the rod 2 is a threaded rod, the length of the rod 2 protruding out of the end of the opening is larger than the thickness of the connecting steel plate, and it is ensured that the threaded rod can penetrate through the connecting steel plate and then protrude out of the surface of the connecting steel plate so as to be connected with a nut and connect and fix the connecting steel plate and the positioning fixture.
Further, the rod member 2 is welded to one side end surface of the first plate member 11 and is perpendicular to the end surface of the first plate member 11. As shown in fig. 1 and 2, the welding position of the rod member 2 is related to the position of the bolt hole preset on the connecting steel plate, and the perpendicularity of the rod member 2 relative to the first plate member 11 directly affects the perpendicularity of the connecting steel plate relative to the i-shaped steel, so the rod member 2 is usually selectively welded to the bottom surface or the top surface of the first plate member 1 to ensure the levelness. The number of the rods 2 can be corresponding to the number of the bolt holes in the connecting steel plate, the more the rods 2 are, the better the positioning effect on the connecting steel plate is, and two rods 2 are generally preferred.
Optionally, a U-shaped groove is formed in the first plate 11, and the rod 2 is welded in the U-shaped groove. In use, the base plate of the first plate member 11 is typically placed against the surface of the i-beam, and the bar member 2 and the connecting steel plate are easily positioned. When the bottom surface and the top surface of first plate 11 can not satisfy the vertical position of member 2, can set up U type groove on first plate 11, U type groove width slightly is greater than the external diameter of member 2, wears to establish member 2 in U type inslot, can adjust member 2 for first plate 11 after the upper and lower position welded fastening, the groove depth in U type groove suitably increases and to carry out suitable spacing to the major axis of member 2, guarantees the straightness that hangs down of member 2 for the 11 terminal surfaces of first plate.
As shown in fig. 1, the welding positioning fixture for the tunnel arch and the connecting steel plate of the present invention further comprises a handle 3, wherein the handle 3 is fixed on the first plate 11 and is located at the top of the first plate 11. The handle 3 is used for moving the positioning fixture, so that the handle 3 is generally a "door" shaped steel bar arranged on the top of the first plate 11, or a plurality of steel bars are welded together to form a gripping part with a handle function.
The utility model discloses a welding position fixture for tunnel bow member and connecting steel plate still includes stiffening plate 4, and stiffening plate 4 is connected between first plate 11 and second plate 12 to and between first plate 11 and the third plate 13. The stiffening plate 4 can increase the stability of the first plate 11 relative to the second plate 12 and the third plate 13, and because the second plate 12 and the third plate 13 are welded perpendicular to the first plate 11, the contact area of the connecting position is small, and the stiffening plate 4 can increase the stability between the plates 1 and prevent tilting, preferably, the stiffening plates 4 are arranged on both sides of the second plate 12, and the stiffening plates 4 are arranged on both sides of the third plate 13.
It should be further noted that, at the position where the second plate 12 and the third plate 13 are welded to the first plate 11, both sides of the second plate 12 and both sides of the third plate 13 are welded. When the rod member 2 is welded to the first plate member 11, both sides of the upper surface and both sides of the lower surface of the rod member 2, which are in contact with the first plate member 11, are also welded. In some embodiments, the distance between the two bars 2 is 12cm, using a 6cm long piece of 20mm screw steel.
The utility model provides a welding position fixture for tunnel bow member and connecting steel plate for connect I18I-steel and connecting steel plate, convenient welding is compared in traditional handicraft, and the construction is simpler, and the location is accurate, and steel bow member welding quality is high.
