[0002] The steel-concrete composite beam is a combined structure formed by a profile steel and a concrete bridge deck. The profile steel and the concrete deck are connected through shearing pins, and are combined together through the shearing pins arranged on the top of the profile steel to form the steel-concrete composite beam, so that the profile steel and the concrete deck can bear force together. During construction, the accuracy of the positioning of the shearing pins directly affects the stress state of the shearing pins in the steel-concrete composite beam, thereby affecting the bearing capacity of the entire steel-concrete composite beam. Therefore, a shearing pin welding positioning tool for the steel-concrete composite beam is needed.

[0003] The profile steel types in the existing steel-concrete composite beam are various, such as I-beams, corrugated steel, steel pipes, etc. When positioning the shearing pins on different types of profile steel, the positioning tool cannot be universal. The existing shearing pin templates are mostly flat, so when facing other shapes of cross sections, the template needs to be re-customized or the traditional inkpot line shooting method is used. The former increases the cost, and the latter delays the construction progress and has low accuracy. Therefore, a shearing pin welding positioning tool that can be used for various types of profile steel is needed. SUMMARY

[0020] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0021] like Figures 1-3 The shear stud welding positioning tool shown includes: multiple positioning steel bars 1, multiple positioning steel pipes 5, two guide rods 2, and four positioning strong magnets 6. The number of positioning steel pipes 5 is twice the number of positioning steel bars 1. Each positioning steel bar 1 has a positioning steel pipe 5 at both ends.

[0022] Each positioning steel bar 1 in this embodiment includes six spaced positioning pieces and five hinge components disposed between the six positioning pieces.

[0023] The positioning steel strip 1 slides with the guide rod 2 via positioning steel pipes 5 installed at both ends, thereby adjusting the distance between two adjacent positioning steel strips 1 and the distribution position of each positioning steel strip 1. In some embodiments, the positioning steel pipe 5 is provided with a locking member that locks with the guide rod 2. The locking member can be a bolt, which passes through the positioning steel pipe 5 and abuts against the guide rod 2 to lock and fix the positioning steel pipe 5, thus restricting the sliding of the positioning steel pipe 5 on the guide rod 2.

[0024] The guide rod 2 is equipped with scale lines, which can be used to precisely control the setting position of the positioning steel bar 1 and improve the positioning accuracy of the shear nail.

[0025] Of course, the number of positioning pieces on the positioning steel strip 1 is not limited to the six in this embodiment. The number of positioning pieces can be adjusted according to construction needs.

[0026] The number of positioning pieces on the positioning steel strip 1 can be flexibly increased or decreased, and the hinge assembly and positioning pieces can be connected by a detachable structure, such as bolts.

[0027] The hinge assembly can adopt two structural forms. One form includes two telescopic rods 4 and a universal joint 3 connecting the two telescopic rods 4; the other end of each telescopic rod 4 is connected to two adjacent positioning plates. The other form includes two universal joints 3 and a telescopic rod 4 connecting the two universal joints 3; each universal joint 3 is hinged to two adjacent positioning plates. Both structural forms of the hinge assembly allow for angle and distance adjustment of the positioning plates at both ends of the hinge assembly. The telescopic rod 4 adopts the commonly used threaded telescopic rod structure.

[0028] The contour line of the positioning hole on each positioning sheet is a closed annular curve, thereby forming a variable-diameter hole, such as an ellipse with one end large and the other end small. The positioning hole with the annular curve can be applicable to shear pins with different diameters.

[0029] Positioning strong magnets 6 are installed on the positioning sheets at both ends of the guide rod 2. The positioning strong magnets 6 are used for magnetic fixation with the steel beam, thereby temporarily fixing the positioning tool of the embodiment on the steel beam for welding of the shear pins.

[0030] As shown in Figure 3 The outer wall of the positioning steel pipe 5 is provided with a splicing piece, two opposite ends of the splicing piece along the length direction of the positioning steel pipe 5 are respectively provided with a male head 8 and a female head 7, and the opposite male head 8 and female head 7 of the splicing pieces of two adjacent positioning steel pipes 5 on the guide rod 2 are inserted and matched. The male head 8 includes a protruding block, and the female head 7 includes a recess. When two positioning steel pipes 5 are spliced by using the splicing piece, the male head 8 of one splicing piece is inserted into the female head 7 of the other splicing piece, the connection of the two positioning steel pipes 5 is realized, and the splicing and fixation of multiple positioning steel strips 1 can be realized according to the needs. The protruding block of the embodiment adopts a trapezoidal block, and the recess adopts a trapezoidal groove. The splicing piece can also be connected by using a magnetic attraction structure, such as a magnetic block to realize the splicing of two positioning steel pipes 5.

[0031] As shown in Figure 4 The positioning tool of the embodiment is laid on a steel plate with a wave-shaped cross section, the angle and distance between the positioning sheets are adjusted according to the profile of the steel plate, the positioning hole is located above the target position of the steel plate where the shear pin needs to be welded, the shear pin 9 is inserted through the positioning hole after the positioning tool is magnetically fixed with the steel plate by using the positioning strong magnet 6, and the shear pin 9 can be welded at the target position of the steel plate.

[0032] As shown in Figure 5 The positioning tool of the embodiment is laid on a steel main beam with a circular cross section, the angle and distance between the positioning sheets are adjusted according to the profile of the steel main beam, the positioning sheets are attached to the steel main beam, and the positioning hole is located at the target position of the shear pin of the steel main beam, and the welding work can be performed by installing the shear pin 9.

[0033] The above is only a preferred embodiment of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solutions falling within the concept of the present application shall be considered as falling within the protection scope of the present application.
