Abstract
Claims
1. A cover plate type drill jig for a H-shaped steel web, characterized by, include: The drilling template (1) has arrayed reference holes (101) on the top, the reference holes (101) correspond to the parts of the web of the I-beam that need to be drilled, and the reference holes (101) are fitted with drilling sleeves (102). The positioning element (2) has a positioning hole (203) on one side, which is used to cooperate with the pre-drilled hole of the I-beam flange plate to achieve precise positioning through the punch (204). Its bottom is fixedly connected to the top end of the drilling template (1) by the wing bolt (202). The F-type clamp (3) has a first T-type screw (301) and a second T-type screw (302) threadedly connected to its two ends respectively. The first T-type screw (301) is used to cooperate with the F-type clamp (3) to clamp the flange of the I-beam, and the second T-type screw (302) is used to cooperate with the F-type clamp (3) to clamp the drill template (1) and the web of the I-beam.
2. A cover plate type drill jig for a H-shaped steel web according to claim 1, wherein The drilling template (1) is a rectangular steel plate, the size of which matches the web of the I-beam, and the thickness is 15-30mm.
3. A cover plate type drill jig for a H-beam web according to claim 1 or 2, wherein The top of the drilled template (1) has two symmetrical lifting holes, and each of the two lifting holes is equipped with a matching eye bolt (106).
4. A cover plate type drill jig for a H-beam web according to claim 3, wherein The top of the drilling template (1) is provided with a positioning groove (104) at the end away from the positioning element (2). The center of the positioning groove (104) is engraved with a scale line to assist in the position correction of the drilling template (1).
5. A cover plate type drill jig for a H-beam web according to claim 1, wherein The drill sleeve (102) is interference-fitted with the reference hole (101) to ensure that the drill sleeve (102) is firmly fixed.
6. A cover plate type drill jig for a H-beam web according to claim 5, wherein The drill sleeve (102) has a variety of inner diameters and hole spacings so that it can be replaced according to the required hole diameter and hole spacing.
