Description

Technical Field

[0001] The present application relates to the technical field of steel structures, and in particular to a positioning device and a positioning method for bolt holes in a connecting plate. Background Art

[0002] During tunnel construction, steel frames are often used for initial support to limit harmful deformation of the surrounding rock. Currently, these steel frames are typically constructed using H-shaped steel. Specifically, connecting plates are welded to the ends of the H-shaped steel and bolt holes are drilled in the connecting plates to connect the two plates.

[0003] However, during the actual installation process, due to manufacturing errors, the bolt holes on two adjacent connecting plates often cannot be aligned, which often requires a lot of manpower and time to calibrate or perform secondary processing on the bolt holes, resulting in low construction efficiency and high labor intensity. Summary of the Invention

[0006] A positioning device for a bolt hole of a connecting plate comprises a positioning seat with a first positioning surface. The positioning seat is provided with a positioning pin extending outward in a direction parallel to the first positioning surface.

[0007] Furthermore, the number of the positioning pins is two, and a plane passing through the axes of the two positioning pins is parallel to the first positioning surface.

[0008] Furthermore, the positioning seat has two parallel second positioning surfaces on opposite sides, the second positioning surfaces are perpendicular to the first positioning surface, and the second positioning surfaces are parallel to the axis of the positioning pin.

[0009] Furthermore, the positioning seat includes two parallel mounting plates and a fixing plate fixed between the two mounting plates, the positioning pin is fixed on the surface of one of the mounting plates, the mounting plate has a first side surface, and the first side surfaces of the two mounting plates are coplanar and form the first positioning surface.

[0010] Furthermore, the mounting plate has two second side surfaces arranged in parallel and located on both sides of the first side surface. The first side surfaces of the two mounting plates correspond to each other one by one and are coplanar to form the second positioning surface.

[0011] Furthermore, the fixing plate is parallel to the first side surface.

[0012] Furthermore, both side surfaces of the fixing plate located between the two mounting plates are concave arc structures.

[0016] Beneficial effects of this application:

[0017] The embodiment of the present application provides a positioning device and positioning method for the bolt holes of the connecting plates. Before the connecting plates are welded to the H-shaped steel, the positioning pins are inserted into the bolt holes of the two connecting plates for precise positioning.

[0030] See also Figures 1 to 4 A positioning device for a bolt hole in a connecting plate provided in an embodiment of the present application includes a positioning seat 1 having a first positioning surface 3 , and the positioning seat 1 has a positioning pin 2 extending outward in a direction parallel to the first positioning surface 3 .

[0031] See also Figure 1, the bottom of the positioning seat 1 has a first positioning surface 3, and the first positioning surface 3 is a horizontally arranged plane. The axial direction of the positioning pin 2 is parallel to the first positioning surface 3, and one end of the positioning pin 2 is fixedly connected to the positioning seat 1. The diameter of the positioning pin 2 is adapted to the diameter of the bolt hole 12 on the connecting plate 11, so that the positioning pin 2 is inserted into the bolt hole 12 for positioning. The number of positioning pins 2 is consistent with the number of bolt holes 12 on the connecting plate 11. For example, when there is one bolt hole 12 on the connecting plate 11, the number of positioning pins 2 is one; when there are two bolt holes 12 on the connecting plate 11, the number of positioning pins 2 is two, and the two positioning pins 2 can be inserted into the two bolt holes 12 respectively. In this embodiment, the number of positioning pins 2 is two, and the plane passing through the axes of the two positioning pins 2 is parallel to the first positioning surface 3.

[0032] An embodiment of the present application provides a positioning device for a connecting plate bolt hole, which provides a first positioning surface 3 on a positioning seat 1 for contacting the surface of the web of the H-shaped steel 10 during positioning, so that the distance between the positioning pin 2 and the web of the H-shaped steel 10 remains unchanged; by providing a positioning pin 2, the positioning pin 2 can be inserted into the bolt holes 12 of two adjacent connecting plates 11 to pre-position the two connecting plates 11 before welding the connecting plates 11 to the H-shaped steel 10.

[0033] See also Figure 1 、 Figure 2 In some other embodiments, two parallel second positioning surfaces 4 are provided on opposite sides of the positioning seat 1. The second positioning surfaces 4 are perpendicular to the first positioning surface 3 and parallel to the axis of the positioning pin 2. For example, the distance between the two second positioning surfaces 4 should be consistent with the distance between the inner sides of the two flanges of the H-beam 10. After the first positioning surface 3 of the positioning seat 1 is brought into contact with the surface of the web of the H-beam 10, the second positioning surfaces 4 can be brought into contact with the inner sides of the flanges of the H-beam 10. This prevents the positioning seat 1 from shaking left and right during its movement along the length direction of the H-beam 10.

[0034] See also Figure 3 、 Figure 4In some other embodiments, the positioning seat 1 includes two parallel mounting plates 5 and a fixing plate 6 fixed between the two mounting plates 5. The positioning pin 2 is fixed to the surface of one of the mounting plates 5. The mounting plate 5 has a first side surface 7. The first side surfaces 7 of the two mounting plates 5 are coplanar and form a first positioning surface 3. The mounting plate 5 has two parallel second side surfaces 8 located on both sides of the first side surface 7. The first side surfaces 7 on the two mounting plates 5 correspond one to one and are coplanar to form a second positioning surface 4. Exemplarily, the fixing plate 6 is parallel to the first side surface 7. Both sides of the fixing plate 6 located between the two mounting plates 5 are concave arc structures. In this way, when the positioning seat 1 is placed on the web of the H-beam 10, the fixing plate 6 can be prevented from contacting the wing plate of the H-beam 10, thereby reducing the friction of the positioning seat 1 during movement.

[0035] See also Figures 1 to 4 In some other embodiments, in order to facilitate the grasping of the positioning seat 1, a handle 9 is provided on the positioning seat 1. Exemplarily, the handle 9 is an arc-shaped rod-shaped structure, and both ends of the handle 9 are fixedly connected to the positioning seat 1.

[0037] The embodiment of the present application provides a positioning device and positioning method for the bolt holes of the connecting plates. Before the connecting plates 11 are welded to the H-shaped steel 10, the positioning pins 2 are inserted into the bolt holes 12 of the two connecting plates 11 for precise positioning. Then, the connecting plates 11 are welded to the H-shaped steel 10. In this way, when the H-shaped steel 10 is subsequently assembled together to form a steel frame, the bolt holes 12 between the two adjacent connecting plates 11 can be quickly and accurately aligned. Compared with the existing technology, the construction efficiency is improved and the labor intensity is reduced.
