Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, specifically a guardrail. Background Technology

[0002] Traffic road guardrails or guardrails in tourist scenic areas are mainly installed for personnel safety. In the existing technology, the vast majority of guardrails are formed by square tube structure columns, baffles and intermediate support connecting rods. The columns, baffles and intermediate support connecting rods are mainly welded to form independent units, and then the welded units are transported to the site for installation.

[0003] This application improves upon the existing technology, in which the baffle between two columns is plate-shaped, and multiple baffles are vertically connected to form a guardrail, splicing together to form a solid structure. Such a guardrail blocks the view from both the front and back, making it impossible to observe the external condition of the guardrail.

[0004] The existing guardrails are relatively complicated to install and assemble. Adjacent panels are stacked one by one and require welding, painting and other processes, resulting in low assembly efficiency. If disassembly and repair are needed later, the welded structure makes repair difficult and requires the entire guardrail to be disassembled and replaced.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this utility model is to provide a protective railing to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a guardrail, comprising a post and several baffles, wherein the two ends of the baffles are connected to the post, the baffles are spaced apart along the height direction of the post, and the cross-section of the baffles is a parallelogram structure.

[0008] As a further embodiment of this utility model: mounting grooves are provided on the opposite sides of the two adjacent columns.

[0009] As a further embodiment of this utility model, a spacer block is also provided between two adjacent plurality of baffles.

[0010] As a further embodiment of this utility model: a limiting groove is also provided on the inner wall of the mounting groove, and there are two sets of limiting grooves. The two sets of limiting grooves are symmetrically arranged on both sides of the mounting groove, and a limiting protrusion that can be inserted into the limiting groove is provided on the spacer block.

[0011] As a further embodiment of this utility model: the limiting groove is provided along the length direction of the mounting groove, and the number is at least one.

[0012] As a further embodiment of this utility model: a limiting block capable of fixing the baffle is provided at the top of the mounting groove, the limiting block having a trapezoidal cross section, and the limiting block being connected to the baffle by screws.

[0013] As a further embodiment of this utility model, the limiting block is provided with an insert that can be inserted into the limiting groove.

[0014] As a further embodiment of this utility model: the middle part of the baffle rail also has a reinforcing rib one, and the middle part of the limiting block also has a reinforcing rib two.

[0015] As a further embodiment of this utility model: the baffle is made of aluminum alloy material, and the aluminum alloy is covered with a wood-plastic composite surface.

[0016] As a further embodiment of this utility model: a top cover plate is also installed on the top of the column and the top of the limiting block, and the top cover plate is provided with an insertion port that matches the cross-sectional shape of the column.

[0017] This utility model has the following beneficial effects: This guardrail is formed by stacking multiple parallelogram-shaped baffles and spacers in sequence and embedding them into the mounting slots of two adjacent posts. This creates a gap between the two adjacent baffles, allowing workers to see the outside of the guardrail from between the two adjacent baffles when their view is directly above the guardrail, but not from the other side.

[0018] By sequentially installing spacer blocks and baffles into the mounting slots of the two columns, and then installing a limiting block on the top baffle to fix and limit its position, this connection and installation method is quick and convenient. The spacer blocks and baffles are connected in the mounting slots through the connection method of the limiting slots and inserts, which increases the tightness and stability of the connection. This overcomes the disadvantage of unreliable strength performance of welding, and has the characteristics of convenient installation and disassembly, solving the problem of complex installation process.

[0019] This guardrail can be installed with multiple posts, and then baffles and spacers can be installed between adjacent posts to quickly assemble the guardrail. The posts can be effectively configured according to the terrain where the guardrail needs to be installed, making full use of space and making installation simple and convenient.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Figure 1-7 This utility model provides an embodiment of a guardrail, comprising posts 1 and several baffles 2. The number of posts 1 is at least two. The two ends of the baffles 2 are respectively connected to adjacent posts 1. The baffles 2 are spaced apart along the height direction of the posts 1. The cross-section of the baffles 2 is a parallelogram structure. The sides of two adjacent posts 1 are provided with mounting grooves 4. Spacer blocks 3 are also provided between two adjacent baffles 2. Limiting grooves 5 are also provided on the inner wall of the mounting grooves 4. There are two sets of limiting grooves 5. The two sets of limiting grooves 5 are symmetrically arranged on both sides of the mounting grooves 4. The spacer blocks 3 are provided with limiting protrusions 11 that can be inserted into the limiting grooves 5. The limiting grooves 5 are arranged along the length direction of the mounting grooves 4, and there is at least one limiting block 6 that can fix the baffles 2. The cross-section of the limiting block 6 is trapezoidal. The limiting block 6 is connected to the baffles 2 by screws 8. The limiting block 6 is provided with inserts 7 that can be inserted into the limiting grooves 5.

[0028] The middle part of the baffle 2 also has a reinforcing rib 9, and the middle part of the limiting block 6 also has a reinforcing rib 10.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in use, firstly, multiple posts 1 are laid according to the terrain conditions. Then, the two ends of the baffle 2 are inserted into the mounting slots 4 of two opposite posts 1. Then, the spacer block 3 is embedded into the mounting slot 4, and the insert strips 7 on both sides of the spacer block 3 are embedded into the limiting slots 5 of the mounting slot 4. Then, the baffle 2 and the spacer block 3 are inserted into the mounting slot 4 in sequence to finally form a guardrail. By setting multiple baffles 2 with a cross section of parallelogram, and installing spacer blocks 3 with a cross section of parallelogram between two adjacent baffles 2, a gap is left between two adjacent baffles 2.

[0030] Then, a limiting block 6 is installed at the topmost baffle 2 to fix and limit it. The limiting block 6 has a trapezoidal cross section, and there are also inserts 7 on both sides of the limiting block 6, which can be embedded in the limiting groove 5 in the mounting groove 4 to further increase the tightness of the connection between the limiting block 6 and the column 1. Screws 8 are connected between the limiting block 6 and the baffle 2 to fix it, so that the screws 8 pass through the limiting block 6 and are screwed onto the baffle 2. An end cap is also fastened to the top of the limiting block 6 and the column 1 for aesthetic purposes.

[0031] Baffle 2 is manufactured using a 360-degree co-extrusion process with aluminum and plastic. A layer of HDPE high-polymer modified plastic is coated onto the aluminum surface, resulting in a diverse range of colors, good colorfastness, a strong wood-like texture, corrosion resistance, acid and alkali resistance, good dimensional stability, and resistance to deformation. To address the difference in expansion coefficients between aluminum and plastic, a specially formulated environmentally friendly coupling agent is used for co-extrusion, ensuring a strong bond between the aluminum and plastic. After a 72-hour boiling test at 100 degrees Celsius, no delamination was observed.

[0032] The bottom of column 1 also has a contact plate, and holes for bolts and other installations are opened at the four corners of the contact plate, so that the two columns 1 can be installed on the ground, balcony or other places.

[0033] The cross-section of the column 1 is rectangular, and an installation slot 4 is provided on the side of the rectangle. Multiple installation slots 4 can be provided during use. Installation slots 4 are provided on the opposite sides of two adjacent columns 1. Three installation slots 4 are provided on a single column 1, and the included angle between each installation slot 4 is 90 degrees. In this way, three guardrails can be installed on a single column 1. They can be assembled according to the required usage scenario, which increases their practicality. They can be spliced ​​and installed according to the usage scenario. During installation, only two corresponding columns 1 need to be set symmetrically first, and the installation slots 4 on the two columns 1 need to be opposite each other. Then, the baffle 2 and the spacer block 3 can be embedded in the two opposite installation slots 4.

[0034] like Figure 7 As shown in this application, baffles 2 and spacers 3 are installed sequentially and spaced apart in the mounting groove 4 of the column 1, and the cross-sections of baffles 2 and spacers 3 are both parallelograms. This leaves a gap between two adjacent baffles 2, so that if the worker's view is directly above the guardrail, he can see the outside of the guardrail through the gap between the two adjacent baffles 2, but if he is on the other side of the guardrail, he cannot see it.

[0035] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. At the same time, the electrical components mentioned in this application are all connected to an external power supply and control switch when in use.
