Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, and particularly relates to an assembled guardrail structure. Background Art

[0002] Prefabricated guardrails are mainly made of columns, beams, baffles, diagonal braces, horizontal braces, reinforcement ribs and other components, which are standardized in production and standardized in splicing and installation according to design and production standards, dimensions and processes. All bolts can be installed on the construction site, thus achieving efficient production, fast transportation and splicing installation, which greatly reduces the procurement cost of the product, and the structural prefabricated components can be recycled and reused.

[0003] However, the existing prefabricated guardrail structure has certain prefabricated structural limitations. The prefabricated standard structure needs to determine the installation dimensions and installation site specifications before installation, and the directional fixed assembly structure also has certain requirements for the splicing method of the structural parts, which makes the existing prefabricated structure have a small scope of application and high prefabrication recovery costs. Utility Model Content

[0004] In view of the above-mentioned technical problems existing in the prior art, an assembled guardrail structure is provided to solve the problems in the prior art that the size of the prefabricated structure and the fixed assembly method are limited, the loss of the installation structure parts caused by the on-site installation also increases the prefabrication recovery cost, and the applicability is limited.

[0005] The purpose and effect of the utility model are achieved by the following specific technical means:

[0006] An assembled guardrail structure comprises a column bolt tube, an axle rod and a guardrail plate, wherein the column bolt tube is two cylindrical tube bodies arranged axially symmetrically, the axle rod is inserted between the two cylindrical tube bodies, a column head is inserted at the bottom end of the column bolt tube, and a limit groove is hollowed out on the bottom surface of the column head;

[0007] An assembly sleeve is sleeved on the shaft rod, a crank is arranged on the outside of the assembly sleeve, and an integrally formed clamping plate extends outward from the crank, plugs are protruding on both sides of the guardrail plate, and an assembly port matching the plug is arranged on the outside opening of the clamping plate.

[0008] A further preferred solution is that a latch piece is extended from one end of the column head relative to the limiting groove, and the latch piece is plugged and fixed to the column bolt tube.

[0009] A further preferred solution is that thread grooves are formed at both ends of the shaft rod, and a thread matching the shaft rod is formed at the inner end of the tube opening of the column bolt tube.

[0010] A further preferred solution: the guardrail plate is a metal perforated plate, and matching concave-convex edge structures are formed on the upper and lower sides of the guardrail plate respectively.

[0011] A further preferred solution is that the assembly sleeve is slotted with a crank slot, and the crank is hingedly matched with the crank slot.

[0012] A further preferred solution: the connector is an expansion type stud.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] Compared with the traditional bolt splicing assembly method, this kind of prefabricated guardrail structure mainly adopts the plug-in type of front and back assembly to complete the splicing and fixation of the column bolt tube, the axle rod and the guardrail plate. The guardrail plate adopts a short and wide plate structure, and multiple guardrail plates can be assembled between the column bolt tubes according to the actual installation size. At the same time, the assembly kit fixed with its column bolt tube can adjust the relative height on the axle rod according to the actual guardrail enclosure requirements, which is convenient for custom fixation during assembly, avoiding the traditional assembly method's strict requirements on the installation sequence of prefabricated structural parts, improving the applicability of the structure and reducing installation costs.

[0020] See also Figure 1-4 , the embodiments of the utility model are further described;

[0021] An assembled guardrail structure includes a column bolt tube 1, an axle rod 2 and a guardrail plate 3. The column bolt tube 1 is two cylindrical tube bodies arranged axially symmetrically. The axle rod 2 is inserted between the two cylindrical tube bodies. A column head 6 is inserted at the bottom end of the column bolt tube 1, and a limit groove 11 is hollowed out on the bottom surface of the column head 6.

[0022] The shaft member 2 is sleeved with an assembly sleeve 4, a crank 9 is provided on the outer side of the assembly sleeve 4, and an integrally formed clamping plate 5 extends outward from the crank 9, and plugs 8 are protrudingly provided on both sides of the guardrail plate 3, and an assembly port 10 matching the plugs 8 is provided on the outer opening of the clamping plate 5;

[0023] After the bolt 1 is in place, the bolt 12 can be easily installed on the fixing plate 3. When the bolt 12 is in place, the fixing plate 3 can be easily installed on the fixing plate 3.

[0024] Furthermore, a latch member 12 is formed on one end of the column head 6 extending relative to the limiting groove 11, and the latch member 12 is plugged and fixed to the column bolt tube 1. The latch member 12 serves as an extension structure of the limiting groove 11 to the connecting end of the column bolt tube 1, and extends the column head 6 to the ground fixing point position and the connection structure of the entire column bolt tube 1 in a vertical fixing manner, thereby reinforcing the stability of the column bolt tube 1, the column head 6, and the ground fixing position.

[0025] Furthermore, thread grooves are formed at both ends of the shaft member 2, and a thread matching the shaft member 2 is formed at the inner end of the pipe mouth of the column bolt tube 1. Compared with the structure of the shaft member 2 and the column bolt tube 1 that adopts plug-in matching, the thread at the end of the shaft member 2 can be utilized. While utilizing the thread matching to strengthen the stability of the connection structure, the length ratio of the shaft member 2 relative to the column bolt tube 1 can be adjusted according to the length of the thread screw-in, which makes it convenient to subsequently adjust the size specifications of the guardrail structure according to the actual installation size, thereby further improving the applicability of the structure.

[0026] On the basis of the above, the guardrail plate 3 is a metal perforated plate, and the upper and lower sides of the guardrail plate 3 are respectively formed with matching concave and convex edge structures. The upper and lower matching edge structures can be matched and docked with the upper and lower adjacent guardrail plates 3 in conjunction with the subsequent multi-sided enclosure installation method. As a perforated plate, the guardrail plate 3 has breathable and windproof properties.

[0027] Furthermore, the assembly sleeve 4 is provided with a crank slot 7, and the crank 9 is hingedly connected with the crank slot 7. Figure 3 As shown, the crank 9 and crank groove 7 structure can facilitate the subsequent adjustment of the assembly angle between the assembly set 4 and the clamping plate 5 by the hinged movement of the crank 9 along the crank groove 7, that is, to adjust the angle formed between the column bolt tube 1 and the adjacent guardrail plate 3, thereby further improving the applicability of the structure.

[0028] Furthermore, the connector 8 is an expansion bolt, which improves the structural strength and stability of the plug-in assembly of the guardrail plate 3 and the clamping plate 5 by means of an expansion bolt connection.
