Description
Technical Field
[0001] This utility model belongs to the field of building materials technology, and specifically relates to a welding stud that facilitates vertical welding. Background Technology
[0002] Cylindrical head studs, short for arc stud welding studs, are a type of high-strength, rigid fastener used in increasingly large public buildings and high-rise buildings. These structures are often reinforced concrete structures, and cylindrical head studs have gained widespread use in this field to ensure good bonding and coordinated operation between steel components, as evidenced by numerous experimental and engineering applications. Applications include industrial plant construction, highways, railways, bridges, towers, automobiles, energy and transportation infrastructure, airports, stations, power plants, pipeline supports, lifting machinery, and other steel structure projects.
[0003] A high-energy-absorbing welding stud disclosed in patent CN215890726U includes a columnar welding stud body made of high-efficiency energy-absorbing alloy steel and a stud head located at the front end of the welding stud body. The stud head has anti-slip embossing around its perimeter. An arc-starting body is embedded at the end of the welding stud body. The end of the arc-starting body is flat. A ceramic ring that mates with the welding stud body is fitted at the end of the welding stud body. The welding stud of this solution has the advantages of easy verticality adjustment, good energy absorption effect, and good fastening with the welding torch clamp.
[0004] In the above scheme, a drain groove is opened at the front end of the welding stud body and the arc-starting body needs to concentrate the charge, so its protruding plane is not too large. This will result in the inability to determine whether the welding stud is perpendicular to the steel frame by relying on end face contact, and the stud head part does not have a structure for positioning with the welding stud gun, which cannot guarantee that the welding stud can be connected vertically, thereby reducing the welding effect. Utility Model Content
[0005] The purpose of this invention is to address the aforementioned problems by providing a welding stud that facilitates vertical welding and solves the technical issues described above.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A welding stud that facilitates vertical welding includes a stud body and a stud head.

Attached Figure Description
[0019] Figure 1 This is a schematic diagram of the overall structure of this utility model.
[0020] Figure 2 This is a schematic diagram of the present invention from an axial perspective.
[0021] In the diagram, there are nail body 1, flow channel 11, arc-starting body 12, arc-starting ball channel 13, weld filler channel 14, nail body blocking ring 15, nail head 2, limiting opening hole 21, and anti-slip texture 22. Detailed Implementation
[0022] The following are specific embodiments of the utility model, which are described in conjunction with the accompanying drawings to further illustrate the technical solution of the utility model. However, the utility model is not limited to these embodiments.
[0023] Example 1
[0024] like Figures 1-2 As shown, a welding stud that facilitates vertical welding includes a stud body 1 and a stud head 2. One end of the stud body 1 is disposed on the stud head 2. The stud body 1 is characterized by having a plurality of drainage grooves 11 that extend to the edge of the end face evenly disposed on the other end of the stud body 1. An arc-guiding body 12 protruding from the end face is disposed at the position where the drainage grooves 11 converge. The stud head 2 is provided with a plurality of limiting opening holes 21 that are opened along the length direction of the stud body 1.
[0025] Specifically, a flow channel is provided at the welding end of the stud body to evenly guide the initially molten arc-starting material to the edge of the end face, preventing the stud body from not being vertically positioned on the steel frame due to uneven distribution of the molten fluid. Simultaneously, a limiting opening is provided on the stud head for positioning when used with a welding stud gun, effectively ensuring the verticality of the stud and preventing circumferential rotation of the stud during solidification, thereby improving the connection quality between the stud and the steel frame.
[0026] In this embodiment, an arc-initiating ball groove 13 is provided at the end of the nail body 1 away from the nail body 1. The arc-initiating ball groove 13 communicates with the drainage groove 11, and the arc-initiating body 12 is embedded in the arc-initiating ball groove 13.
[0027] After the arc-starting body 12 begins to melt, it concentrates in the arc-starting ball groove 13. As the end face comes into contact with the steel frame, more molten iron than the volume of the arc-starting ball groove 13 is squeezed outward from the end face through the guide groove 11. This not only avoids the problem of uneven distribution of molten iron and skewed welding studs, but also discharges welding slag at the same time to ensure welding quality.
[0028] In this embodiment, a weld filling groove 14 is provided along the edge of the end face of the nail body 1 away from the nail body 1, and the weld filling groove 14 is connected to each drainage groove 11.
[0029] A ring-shaped weld filling groove is opened at the edge of the end face of the nail body.
[0030] In this embodiment, the limiting opening holes 21 are evenly distributed around the circular nail head 2, and the inner wall of the limiting opening holes 21 is tangent to the side arc surface of the cylindrical nail body 1.
[0031] Typically, a welding nail gun uses multiple clamping rods to secure the welding nail head. Therefore, a corresponding arc-shaped groove is opened on the edge of the nail head 2 so that the clamping rods can be inserted into the limiting open hole 21, securing the welding nail from multiple angles to ensure its stability during welding.
[0032] The clamping rod can also abut against the arc surface of the nail body 1 after passing through the limiting opening hole 21, which increases the contact point between the clamping rod and the welding nail in the axial direction and prevents the welding nail from deflecting.
[0033] In this embodiment, anti-slip embossing 22 is provided on the side arc surface of the nail head 2.
[0034] The anti-slip embossing 22 is mainly used to increase the adhesion of the casting layer to the nail head 2 and improve the stability of the casting layer.
[0035] In this embodiment, a detachable nail body blocking ring 15 is provided circumferentially on the nail body 1, and the outer ring wall of the nail body blocking ring 15 is tangent to the inner wall of the limiting opening hole 21.
[0036] Before welding, a nail body retaining ring 15 can be fixedly installed on the nail body 1, which is equivalent to another small welding nail head to further improve the axial gripping force of the welding nail on the casting layer. Especially when casting in layers, each casting layer can be strengthened by the corresponding nail body retaining ring 15 to enhance the fixing firmness.
[0037] Meanwhile, after the clamping rod passes through the limiting opening hole 21, it can also abut against the outer surface of the nail body blocking ring 15, which increases the contact point between the clamping rod and the welding nail in the axial direction and prevents the welding nail from deflecting.
[0038] In this embodiment, the outer ring surface of the nail body blocking ring 15 is polygonal, and the inner wall of each limiting opening hole 21 is tangent to the corresponding outer ring plane of the nail body blocking ring 15.
[0039] The outer ring of the nail body blocking ring 15 is polygonal, ensuring that the inner wall of each limiting opening hole 21 has an outer ring tangent to it, so that the clamp of the welding nail gun can abut against the outer ring surface.
[0040] Meanwhile, the polygonal nail body blocking ring 15 can increase the circumferential resistance between the weld nail and the casting layer, preventing them from rotating.
[0041] In this embodiment, the nail body 1 is provided with threads starting from the end near the arc-starting body 12, and the nail body blocking ring 15 is fixed to the nail body 1 by the threads.
[0042] The nail body retaining ring 15 can be installed and removed by means of threaded engagement, but it is necessary to ensure that when the nail body retaining ring 15 is rotated to the end of the thread, the outer ring surface can be tangent to the clamping rod.
[0043] Example 2
[0044] The shape of the side of the nail body 1 in Embodiment 1 has been changed. The limiting opening holes 21 are evenly distributed around the circular nail head 2, and the inner wall of the limiting opening holes 21 is tangent to the corresponding side plane of the nail body 1, which is a polygonal column.
[0045] The polygonal nail body 1 can increase the circumferential resistance between the weld nail and the casting layer, preventing them from rotating.
[0046] Example 3
[0047] The shape of the side of the nail head 2 in Embodiment 1 has been changed. The limiting opening holes 21 are evenly distributed on the regular polygonal nail head 2, and the inner wall of the limiting opening holes 21 is tangent to the side arc surface of the cylindrical nail body 1.
[0048] The polygonal nail cap 2 can increase the circumferential resistance between the weld nail and the casting layer, preventing them from rotating.
[0049] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
