Description

Technical Field

[0001] The utility model relates to an articulated assembly guardrail. Background Art

[0002] At present, the known guardrails are made of iron, aluminum, stainless steel and other materials through welding. The welding guardrails are not only troublesome and costly to process, but also cause environmental pollution and harm to the health of relevant personnel due to the smoke and dust during welding. In addition, the welding process causes defects such as deformation and rust of pipe fittings, and the surface paint coating falls off seriously, resulting in high cost of later repair and maintenance, and also requires repainting and other processes in the later stage.

[0003] 0003 Most of the existing guardrails are assembled manually, that is, after multiple holes are opened on the beam, at least two beams are placed in parallel to align the holes on the two beams, and then each longitudinal beam is manually inserted into the corresponding hole. This method is labor-intensive and has low labor efficiency. After insertion, a welding machine is used to weld the insertion parts. Finally, the spraying process is carried out. Since there is a gap at the welding part, the Faraday shielding effect is inevitable in the electrostatic spraying, and some areas will not be attached with protective paint, so the anti-corrosion performance of the entire guardrail is poor.

[0004] The applicant has previously proposed related structural products for assembling guardrails, but during the trial development process, first, abnormal noises are prone to occur, and second, screws are prone to loosening, resulting in poor product quality. Summary of the invention

[0005] The utility model provides an articulated assembly guardrail to solve the above problems. The articulated assembly guardrail can avoid welding and be assembled directly through assembly equipment. The installation is stable and the Faraday shielding effect in electrostatic spraying can be avoided, so that it has better anti-corrosion performance. In addition, the cross beam and the longitudinal beam can be connected with a certain inclination angle to adapt to different terrains. It can also effectively avoid abnormal noise and ensure that the screws are not loose.

[0006] In order to solve the above technical problems, the utility model provides an articulated assembled guardrail with the following structure, which includes at least one transversely arranged crossbeam and multiple longitudinal beams arranged at intervals and vertically, and its structural features are: a plurality of first connecting holes arranged at intervals are provided on the wall of the crossbeam in contact with the longitudinal beam, and a second connecting hole corresponding to the first connecting hole of the crossbeam is provided on the wall of the longitudinal beam in contact with the crossbeam, a connecting device is installed between the first connecting hole and the second connecting hole, and after the connecting device connects the longitudinal beam and the crossbeam, the longitudinal beam can be twisted around the connecting device to set an angle, the connecting device includes a threaded hollow rivet extending into the first connecting hole in the crossbeam, the threaded hollow rivet is provided with a threaded section after passing through the first connecting hole and undergoing a riveting process, a screw that can be screwed into the threaded section is installed in the second connecting hole of the longitudinal beam corresponding to the first connecting hole, and soundproof pads are respectively installed between the screw and the longitudinal beam and the crossbeam.

[0007] The threaded hollow rivet comprises a disc-shaped rear end head, a rivet section in the middle for rivet extrusion, and a threaded section, wherein the threaded section has an internal thread.

[0008] A self-lubricating washer is arranged on the inner surface of the rear end head of the threaded hollow rivet, and the self-lubricating washer is located between the rear end head and the longitudinal beam.

[0009] The spacings between adjacent second connection holes on a plurality of longitudinal beams are consistent, and when more than two cross beams are provided, the first connection holes on adjacent cross beams are provided correspondingly.

[0010] A base is installed at the bottom of the longitudinal beam, and the bottom of the longitudinal beam is connected to the base through a hinge seat.

[0011] The outer wall of the noise-reducing pad is in contact with the inner wall of the longitudinal beam, and the inner wall of the noise-reducing pad is in contact with the outer wall of the insertion section, and the noise-reducing pad gradually becomes thicker from the insertion end to the inside.

[0012] The fixed connection layer is a colloid coated on the outer surface of the screw during the screw installation process.

[0013] The colloid adopts epoxy resin adhesive.

[0014] Compared with the prior art, the above structure has the following advantages: since the longitudinal beam is attached to the cross beam, and the first connecting hole and the second connecting hole are correspondingly arranged, and after the connecting device connects the longitudinal beam and the cross beam, the longitudinal beam can be twisted around the connecting device to set an angle, thereby avoiding welding and directly assembling, and the installation is stable. It can be sprayed first and then assembled, which can effectively avoid the Faraday shielding effect in electrostatic spraying and make it have better anti-corrosion performance. After the cross beam and the longitudinal beam are connected, they can be twisted at a certain angle to adapt to different terrains such as slopes. There is no need to set guardrails of different lengths separately. The soundproof pad can effectively reduce rigid friction and play a buffering role.

[0015] In summary, the utility model has the advantages of stable and reliable installation, convenient and quick installation and good anti-corrosion performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 2 yes Figure 1 A schematic structural diagram of a silent friction plate in an embodiment;

[0018] Figure 3 It is a state diagram when assembling the guardrail in the prior art. DETAILED DESCRIPTION

[0019] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings:

[0020] refer to Figure 3 As shown, in the prior art, the crossbeam is pre-opened, and a plurality of insertion holes are opened on the crossbeam. The crossbeam is placed on a platform, and a single longitudinal beam is manually inserted into the insertion hole for assembly. After assembly, welding is performed at the X position in the figure, so that the crossbeam and the longitudinal beam are firmly connected to form a guardrail. Since the outer dimensions of the longitudinal beam and the dimensions of the insertion hole are very different (reaching about 0.5 mm), the insertion is very inconvenient, the labor efficiency is low and the labor intensity is high, and the welding part is prone to Faraday effect, rust and reduced product service life. And after the above welding, the angles of the crossbeam and the longitudinal beam are fixed, and cannot be installed in different terrains.

[0021] As attached Figure 1 to Figure 2As shown, an embodiment of an articulated assembled guardrail provided by the utility model comprises at least one horizontally arranged crossbeam 1 and a plurality of longitudinal beams 2 arranged at intervals and vertically. In this embodiment, the crossbeam and the longitudinal beam are both made of square tubes. The utility model changes the structure of the crossbeam and the longitudinal beam in the original guardrail, and adopts a method of the crossbeam and the longitudinal beam being attached to each other. The wall of the crossbeam 1 attached to the longitudinal beam is provided with a plurality of first connection holes arranged at intervals, and the wall of the longitudinal beam 2 attached to the crossbeam 1 is provided with a second connection hole arranged corresponding to the first connection hole of the crossbeam. The first connection hole A connecting device is installed between the hole and the second connecting hole, and after the connecting device connects the longitudinal beam 2 and the cross beam 1, the longitudinal beam can be twisted around the connecting device to set an angle. In this embodiment, the connecting device includes a threaded hollow rivet 4 extending into the first connecting hole in the cross beam 1. The threaded hollow rivet passes through the first connecting hole and is provided with a threaded section after a riveting process. A screw 5 that can be screwed into the threaded section is installed in the second connecting hole of the longitudinal beam corresponding to the first connecting hole. A self-lubricating washer 8 is installed on the inner surface of the rear end head of the threaded hollow rivet, and the self-lubricating washer 8 is located between the rear end head and the longitudinal beam. The threaded hollow rivet 4 has a disc-shaped rear end head, a rivet section in the middle for rivet extrusion, and a threaded section, the threaded section has an internal thread, after the threaded hollow rivet is inserted into the first connection hole, after the rivet operation, the rivet section is compressed to form a flat shape, the flat shape and the rear end head clamp the wall of the longitudinal beam together, after the screw is inserted, the screw can be tightened so that the screw is pressed tightly against the wall of the cross beam, after the entire assembly guardrail is assembled, the longitudinal beam can be twisted around the threaded hollow rivet at a certain angle to achieve the inclined installation of the guardrail. This structure no longer requires a welding structure between the longitudinal beam and the cross beam, so it can be assembled after the outer wall of the square tube is sprayed, avoiding the Faraday shielding effect in electrostatic spraying, so that the entire guardrail has better anti-corrosion performance, and the advantage of spraying is that it can avoid the problem of inadequate or uneven spraying, and the corresponding paint powder will also be evenly attached to the hole walls of each of the above holes, thereby greatly enhancing the anti-corrosion performance of the guardrail.

[0022] As shown in the accompanying drawings, a silent friction plate 9 is installed between the section of the cross beam extending into the longitudinal beam (hereinafter referred to as the insertion section) and the inner wall of the longitudinal beam. The structure of the silent friction plate is as follows: Figure 2 As shown in , its outer wall fits with the inner wall of the longitudinal beam and can be a straight surface, and its inner wall fits with the outer wall of the above-mentioned insertion section and can be an inclined surface that gradually becomes thicker from the insertion end inward. Therefore, it can prevent the crossbeam from shaking and prevent rainwater from entering the above-mentioned port to ensure the service life of the entire guardrail.

[0023] As shown in the attached drawings, a fixing connection layer capable of fixing the screw and the threaded section is provided on the section where the screw penetrates the threaded section. The fixing connection layer is a colloid applied to the outer surface of the screw during the screw penetration process. The colloid is an epoxy resin adhesive, and commercially available sealants, structural adhesives, and other epoxy resin adhesives can be used. Before the above penetration process, the above colloid-like epoxy resin adhesive is applied to the corresponding section of the screw. After the penetration process is completed, the epoxy resin adhesive is cured, thereby fixing the screw and the threaded section.

[0024] As shown in the attached drawings, after multiple longitudinal beams and transverse beams are installed, a base 6 is installed at the bottom of the longitudinal beam, and the bottom of the longitudinal beam 2 is connected to the base 6 through a hinge seat 7. On the ground with different heights, the longitudinal beam can be twisted around the bolt to set the angle, and finally the longitudinal beam at the end (external fixing frame) is fixedly connected to ensure that the installation of the entire guardrail is completed.

[0025] The above is a specific structural form of the utility model. The utility model is not limited by the above embodiments. For those skilled in the art, equivalent changes and component replacements based on the specific structure of the utility model are all within the protection scope of the utility model.
