Abstract
Description
Technical Field
[0001] This utility model relates to a connecting nail, specifically a connecting nail for fixing pipes. Background Technology
[0002] Steel structures, as a widely used load-bearing structural system in modern architecture, play a vital role in various buildings such as industrial plants, commercial complexes, and public facilities. In building electromechanical installation engineering, how to reliably fix water, electricity, and gas pipelines to steel structural components has always been a significant technical challenge in engineering practice. The traditional construction process is as follows: First, surface treatment is performed at the predetermined locations on the steel structure, removing the protective paint layer and grinding down to expose the metal substrate; then, connecting base plates, fixing clamps, and other connectors are welded to the steel structure surface using welding processes; after the welds cool, anti-rust primer and topcoat are reapplied to the connectors and surrounding areas; finally, the piping system is fixed to the connectors using bolt connections or secondary welding. The above process has the following drawbacks in practical applications.
[0003] (1) Low construction efficiency: For steel structures that have been coated with protective coatings (such as galvanized components, fireproof coating components or decorative topcoat components), it is necessary to use mechanical grinding or chemical paint removal to remove paint locally. The whole process involves multiple steps such as paint removal, welding, and paint touch-up, which significantly prolongs the construction period and increases labor costs.
[0004] (2) The quality of touch-up painting is difficult to control: During the second touch-up process, the interface treatment of the new and old coatings, the matching of paint film thickness and color consistency are difficult to meet the original factory coating standards.
[0005] (3) Environmental compliance pressure: The metal fumes (including heavy metals such as manganese and chromium) and VOCs emissions generated by welding operations require the configuration of professional purification equipment, which increases the environmental governance costs of construction companies. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model aims to provide a connecting nail for fixing pipes, thereby simplifying construction processes, improving construction efficiency, making the steel structure surface more aesthetically pleasing, and reducing environmental protection costs.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A connecting nail for fixing a pipe includes a drill head, a screw part, an installation part, a connecting part, and a clamping part connected in sequence; the installation part is a straight prism coaxial with the screw part, and the end of the connecting part away from the installation part is provided with a first through hole perpendicular to the axial direction of the installation part, and the clamping part for fixing the pipe is detachably connected to the connecting part through the first through hole.
[0008] As a limitation of this utility model: a limiting shoulder with a radial dimension larger than that of the screw part is fixed between the screw part and the mounting part.
[0009] As a limitation of this utility model, the radial dimension of the mounting part is greater than the radial dimension of the connecting part.
[0010] As a limitation of this utility model: the mounting part is a regular hexagonal prism.
[0011] As a limitation of this utility model: the end of the connecting part away from the mounting part forms a flat plate structure parallel to the axial direction of the mounting part, and the first through hole is opened through the flat plate structure.
[0012] As a limitation of this utility model: the clamping part includes a semi-circular first clamp and a semi-circular second clamp. One end of the first clamp and the second clamp forms a mounting plate that extends radially outward along the clamping part. The mounting plate is detachably connected to the flat plate structure of the mounting part through a first through hole. The other ends of the first clamp and the second clamp are joined together to form a circular clamping part.
[0013] As a limitation of this utility model: the ends of the first clamp and the second clamp used for splicing are formed with curved ends that can be spliced together.
[0014] As a limitation of this utility model: the drill bit includes two cutting edges symmetrically arranged around the axis of the screw section, the cutting edges including a relatively convex ridge edge and a relatively concave chip removal channel provided on one side of the convex ridge edge.
[0015] As a limitation of this utility model: the cutting edge includes at least one stepped segment, and when the number of stepped segments is greater than one, the diameter of the multiple stepped segments decreases sequentially near the end.
[0016] As a limitation of this utility model: the end of the drill bit gradually narrows to form a tip.
[0017] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:
[0018] This utility model includes a drill bit, a screw rod, an installation part, a connecting part, and a clamping part. The installation part is connected to a drive device, allowing the drill bit and screw rod to be directly inserted into the steel structure through drilling. Then, the clamping part for fixing the pipe is connected, eliminating the need for paint removal and touch-up. This not only simplifies the construction process and improves construction efficiency but also avoids the mismatch in thickness and color between the old and new coatings caused by touch-up painting. Furthermore, it eliminates the need for welding, avoiding metal fumes and VOC emissions and reducing environmental protection costs.
[0019] In summary, this utility model simplifies the construction process, improves construction efficiency, makes the surface of the steel structure more aesthetically pleasing, and reduces environmental protection costs. It is suitable for fixing pipe structures on rigid structural members. Attached Figure Description

It should be understood that the connecting nails for fixing pipes described herein are preferred embodiments and are only used for illustration and explanation of the present invention, and do not constitute a limitation thereof.
[0029] The directional terms or positional relationships used in this utility model, such as "up," "down," "left," and "right," are based on the positional relationships in the accompanying drawings of this utility model. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model.
[0030] This implementation example Figures 1-3 As shown, a connecting nail for fixing a pipe includes, from top to bottom, a drill head 1, a screw part 2, a mounting part 4, a connecting part 5, and a clamping part 7 connected in sequence.
[0031] The drill head 1 is a drill bit structure for self-drilling screws in the prior art. Specifically, the end of the drill head 1 gradually narrows to form a pointed tip for drilling. Based on this, the drill head 1 includes two cutting edges symmetrically arranged around the axis of the screw portion 2. Each cutting edge includes a relatively protruding convex edge 11 and a relatively concave chip removal channel 12 disposed on one side of the convex edge 11. It should be noted that the structure of the drill head 1 can adopt any drill bit structure for self-drilling screws or self-tapping screws in the prior art, and is not limited to this embodiment. In other embodiments, the cutting edge may include two or more stepped segments, with the diameter of the multiple stepped segments decreasing sequentially towards the end. For the specific structure of the cutting edge, please refer to the cutting edge structure in Chinese Utility Model Patent Publication No. CN215786952U.
[0032] The lower end of the drill head 1 is integrally formed with a screw part 2, which is coaxial with the drill head 1. The outer wall of the screw part 2 is formed with an external thread, which can be any type of thread in the prior art, and is not limited to this embodiment.
[0033] A limiting shoulder 3 is integrally formed at the lower end of the screw portion 2 to limit the drilling depth of the connecting nail. In this embodiment, the limiting shoulder 3 has a circular cross-section. In other embodiments, the cross-sectional area of the limiting shoulder 3 can also be other shapes, such as elliptical, as long as the limiting shoulder 3 has a certain thickness and its radial dimension is greater than that of the screw portion 2. Here, the radial dimension refers to the maximum dimension along the radial direction of the connecting nail (or screw portion 2), that is, the maximum radius of the cross-section of the limiting shoulder 3 is greater than the maximum radius of the cross-section of the screw portion 2, and so on.
[0034] The lower end of the limiting shoulder 3 is integrally formed with a mounting part 4 for connecting this embodiment to the installation tool. In this embodiment, the mounting part 4 is a regular hexagonal prism, that is, the mounting part 4 and the screw part 2 form a structure similar to an external hexagonal bolt, which facilitates compatibility with the installation tool. In other embodiments, the mounting part 4 can also be a regular triangular prism, a regular square prism, etc., as long as the mounting part 4 is a right prism coaxial with the screw part 2. In another embodiment, the lower end of the screw part 2 can also be directly integrally formed with the mounting part 4. It should be noted that if the lower end of the screw part 2 is directly integrally formed with the mounting part 4, the radial dimension of the mounting part 4 needs to be larger than the radial dimension of the screw part 2.
[0035] The lower end of the installation part 4 is integrally formed with a connecting part 5 for connecting the clamping part 7. One end of the connecting part 5 close to the installation part 4 is cylindrical and integrally connected to the lower end face of the installation part 4. As the connecting part 5 moves away from the installation part 4, the connecting part 5 gradually transitions and becomes flattened. Finally, a flat plate structure parallel to the axial direction of the installation part 4 is formed at the end of the connecting part 5 away from the installation part 4, and a first through hole 6 perpendicular to the axial direction of the installation part 4 and penetrating the flat plate structure is provided on this flat plate structure. The thickness of this flat plate structure can be adjusted adaptively as needed. The radial dimension of the connecting part 5 is smaller than that of the installation part 4, so that the installation tool can smoothly pass through the connecting part 5 and be connected to the installation part 4.
[0036] The clamping part 7 for fixing the pipeline is detachably connected to the lower end of the connecting part 5 through the first through hole 6. In this embodiment, the clamping part 7 includes a semi-circular first clamping hoop 71 and a semi-circular second clamping hoop 72. One end of the first clamping hoop 71 and the second clamping hoop 72 forms a mounting plate extending radially outward along the clamping part 7. The other ends of the first clamping hoop 71 and the second clamping hoop 72 are joined together to form a circular clamping part 7. The circular dimension of the clamping part 7 can be adjusted adaptively as needed. A second through hole 8 penetrating the mounting plate is provided on the mounting plate. The second through hole 8 is the same size as the first through hole 6. During installation, a threaded fastener (such as a bolt and nut, a screw rod, etc., not shown in the figure) is simultaneously penetrated through the first through hole 6 and the two second through holes 8, so that the mounting plate is detachably connected to the flat plate structure of the installation part 4 through the first through hole 6. The first clamping hoop 71 and the second clamping hoop 72 can be adjusted to other shapes according to the shape of the component to be connected. For example, when the cross-section of the component to be connected is rectangular, the first clamping hoop 71 and the second clamping hoop 72 can be set as a "匚" - shaped structure that is rectangular after being joined together, and so on. Further, the ends of the first clamping hoop 71 and the second clamping hoop 72 for joining together form curved end faces that can be joined together. In this embodiment, the curved end faces include a convex sharp angle and a concave sharp angle formed on the end face of the first clamping hoop 71, and also include a concave sharp angle and a convex sharp angle formed on the end face of the second clamping hoop 72. The convex sharp angle on the first clamping hoop 71 can be joined with the concave sharp angle on the second clamping hoop 72, and the concave sharp angle on the first clamping hoop 71 can be joined with the convex sharp angle on the second clamping hoop 72. In other embodiments, the concave sharp angle and the convex sharp angle can also be replaced with an arc or the like, as long as the end faces of the first clamping hoop 71 and the second clamping hoop 72 can be joined together.
[0037] In this embodiment, the drill head part 1, the screw part 2, the limiting shoulder 3, the installation part 4 and the connecting part 5 are integrally provided. In other embodiments, some of these parts or several of these parts can also be connected by existing detachable methods. For example, the connecting part 5 and the installation part 4 can be connected by a threaded connection method, and again, the installation part 4 and the limiting shoulder 3 can be connected by a threaded connection method, and so on.
[0038] This embodiment can be installed using a customized extended hex socket, either with an electric wrench or a manual wrench. When using an electric wrench, the length of the hex socket needs to be greater than the sum of the lengths of the connecting part 5 and the mounting part 4, allowing it to pass through the connecting part 5 and connect to the mounting part 4. In use, the mounting socket is fitted onto the mounting part 4, and then the mounting socket is installed on the electric wrench. The drill bit 1 is aligned with the target position on the steel structure component, and the electric wrench is turned on until the drill bit 1 and the screw part 2 are screwed into the steel structure component. The mounting socket is then removed, allowing the clamping part 7 to hold the pipe structure. The clamping part 7 is then installed onto the connecting part 5 using threaded fasteners. It should be noted that since the clamping part 7 at the end of this embodiment is a circular structure, this embodiment is not limited to pipe fixing. Other cylindrical structures besides pipe structures can also be fixed using this embodiment, such as cylindrical lines and equipment.
