Description

Technical Field

[0001] This utility model relates to the field of mobile guardrail technology, and in particular to a mobile guardrail structure that can be stacked and arranged to save space. Background Technology

[0002] Typically, at the beginning of construction, a fence is erected around the construction site to isolate the area from the outside. Guard posts are set up at entrances and exits to restrict the entry and exit of personnel, materials, machinery, and vehicles, preventing unauthorized access and providing security. One type of fence uses a rectangular frame made of metal tubing, with a protective netting fixed to the frame. Multiple rectangular frames are joined together horizontally, vertically, or side-by-side to form the desired enclosure. This type of fence is usually transported to the construction site by truck, stacking and loading the rectangular frames one by one, where they are then assembled. Fences enclosing large construction sites often involve numerous rectangular frames, requiring large shipping containers or multiple trips and trucks for transport, resulting in high transportation costs. Therefore, if a more compact stacking of multiple rectangular frames could be achieved without compromising the performance of the frames, saving space and allowing more frames to be loaded into a transport vehicle of the same volume, it would reduce transportation costs. At the same time, this solution also allows the guardrails to be stacked and stored in the storage room when they are not in use, saving space and reducing warehousing costs. Utility Model Content

[0003] In view of this, the present invention proposes a stackable and space-saving movable guardrail structure, which makes the rectangular frames that make up the guardrail stacked more compactly, thereby saving space.

[0004] The technical solution disclosed in this utility model is a stackable, space-saving mobile guardrail structure, comprising a rectangular frame body and a partition structure forming a partition surface within the rectangular frame. The rectangular frame body includes a first vertical tube, a second vertical tube, a first horizontal tube, and a second horizontal tube. The first and second vertical tubes are parallel and aligned on the left and right sides. The first and second vertical tubes are connected to the first horizontal tube near their upper ends, and the first and second vertical tubes are connected to the second horizontal tube near their lower ends. The first and second horizontal tubes are parallel and aligned. The first horizontal tube has a left first flat portion and a right first flat portion at both ends, and the second horizontal tube has a left second flat portion and a right second flat portion at both ends. The flat surfaces of the left first flat portion, right first flat portion, left second flat portion, and right second flat portion are both facing the front and back sides of the partition surface, and the flat surfaces of the left first flat portion, right first flat portion, left second flat portion, and right second flat portion all form symmetrical concave areas.

[0005] Furthermore, the first vertical tube, the second vertical tube, the first horizontal tube, and the second horizontal tube are all made of hollow metal round tubes. The front ends of the left first flat part and the right first flat part of the first horizontal tube are respectively welded to the first vertical tube and the second vertical tube. The front ends of the left second flat part and the right second flat part of the second horizontal tube are respectively welded to the first vertical tube and the second vertical tube.

[0006] Furthermore, the left first flat portion and the right first flat portion are formed by applying pressure to the two symmetrical side walls at both ends of the first horizontal tube to make it flat, and the left second flat portion and the right second flat portion are formed by applying pressure to the two symmetrical side walls at both ends of the second horizontal tube to make it flat. The deformation parts where the left first flat portion and the right first flat portion are connected to the first horizontal tube and the deformation parts where the left second flat portion and the right second flat portion are connected to the second horizontal tube are ensured not to crack.

[0007] Furthermore, the length of the flat portion of the left first flat portion and the left second flat portion is ±5mm of the outer diameter of the first vertical tube, and the length of the flat portion of the right first flat portion and the right second flat portion is ±5mm of the outer diameter of the second vertical tube.

[0008] Furthermore, the first vertical pipe and the second vertical pipe use the same pipe body, and the first horizontal pipe and the second horizontal pipe use the same pipe body.

[0009] Furthermore, the partition structure can be any one of the following: a mesh, a thin plate, or a strip.

[0010] Preferably, since the first and second horizontal tubes are relatively long, resulting in a wider movable guardrail, a third vertical tube is connected at the middle of the first and second horizontal tubes to achieve better support. The two ends of the third vertical tube are respectively connected to the inner sides of the first and second horizontal tubes, and the two ends of the third vertical tube are respectively provided with a middle first flat part and a middle second flat part.

[0011] The beneficial effects of this utility model are as follows: The movable guardrail structure designed in this technical solution connects several movable guardrail structures disclosed in this solution left and right to form the required wall-like protective fence. Before assembling into a wall-like protective fence, several movable guardrail structures are stacked neatly and fixed, and then transported to the construction site in a container loaded onto a transport vehicle.

[0012] The rectangular frame of the movable guardrail structure designed in this scheme is mainly composed of left first flat section and left second flat section, and right first flat section and right second flat section at both ends of the first and second horizontal tubes that make up the rectangular frame. When stacking, from bottom to top, the bottom side wall of the first vertical tube of the second movable guardrail structure presses against the left first flat section and left second flat section of the first movable guardrail structure; the bottom of the right first flat section and right second flat section of the second movable guardrail structure presses against the upper side wall of the second vertical tube of the first movable guardrail structure; the first horizontal tube of the second movable guardrail structure presses against the outside of the first horizontal tube of the first movable guardrail structure; and the second horizontal tube of the second movable guardrail structure is lower than the inside of the second horizontal tube of the first movable guardrail structure. When stacking the third movable guardrail structure, the bottom of the left first flat part and the left second flat part of the third movable guardrail structure presses against the upper side wall of the first vertical tube of the second movable guardrail structure, the bottom side wall of the second vertical tube of the third movable guardrail structure presses against the right first flat part and the right second flat part of the second movable guardrail structure, the first horizontal tube of the third movable guardrail structure presses against the inner side of the first horizontal tube of the second movable guardrail structure, and the second horizontal tube of the third movable guardrail structure is lower than the outer side of the second horizontal tube of the second movable guardrail structure.

[0013] By stacking the pipes in this manner, compared to the rectangular frame using pipes of the same diameter stacked vertically, the height formed by stacking the same number of movable guardrails is less than that of pipes of the same diameter stacked vertically. Therefore, the movable guardrail structure improved by this scheme is more compact in stacking, saves space, and helps save on transportation and storage costs. Attached Figure Description

[0021] The technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this disclosure.

[0022] Example 1

[0023] Please refer to Figures 1 to 3 , Figure 5 This technical solution provides a stackable, space-saving movable guardrail structure, comprising a rectangular frame body and a partition structure forming a partition surface within the rectangular frame. The partition structure uses a mesh, which can be woven from metal wires and fixed within the rectangular frame. The rectangular frame body includes a first vertical tube 11, a second vertical tube 12, a first horizontal tube 21, and a second horizontal tube 22. The first vertical tube 11 and the second vertical tube 12 are parallel and aligned on the left and right sides. The first vertical tube 11 and the second vertical tube 12 are connected to the first horizontal tube 21 near their upper ends, and the first vertical tube 11 and the second vertical tube 12 are connected to the second horizontal tube 22 near their lower ends. The first horizontal tube 21 and the second horizontal tube 22 are parallel and aligned. The first horizontal tube 21 has a left first flat portion 21 at each end. 1. The right first flat portion 21-2 and the second horizontal tube 22 are respectively provided with a left second flat portion 22-1 and a right second flat portion 22-2 at both ends; the flat surfaces of the left first flat portion 21-1, the right first flat portion 21-2, the left second flat portion 22-1 and the right second flat portion 22-2 are both facing the front and back surfaces of the partition surface, and the flat surfaces of the left first flat portion 21-1, the right first flat portion 21-2, the left second flat portion 22-1 and the right second flat portion 22-2 form a symmetrical concave area.

[0024] Furthermore, the first vertical tube 11, the second vertical tube 12, the first horizontal tube 21, and the second horizontal tube 22 are all made of hollow metal round tubes. The front ends of the left first flat portion 21-1 and the right first flat portion 21-2 of the first horizontal tube 21 are welded to the first vertical tube 11 and the second vertical tube 12, respectively. The front ends of the left second flat portion 22-1 and the right second flat portion 22-2 of the second horizontal tube 22 are welded to the first vertical tube 11 and the second vertical tube 12, respectively.

[0025] Furthermore, the left first flat portion 21-1 and the right first flat portion 21-2 apply pressure to the two symmetrical side walls at both ends of the first horizontal tube 21 to form a flat shape, and the left second flat portion 22-1 and the right second flat portion 22-2 apply pressure to the two symmetrical side walls at both ends of the second horizontal tube 22 to form a flat shape. The deformed parts where the left first flat portion 21-1 and the right first flat portion 21-2 are connected to the first horizontal tube 21 and the deformed parts where the left second flat portion 22-1 and the right second flat portion 22-2 are connected to the second horizontal tube 22 are ensured not to crack.

[0026] Furthermore, the flat lengths of the left first flat portion 21-1 and the left second flat portion 22-1 are ±5mm of the outer diameter of the first vertical tube 11, and the flat lengths of the right first flat portion 21-2 and the right second flat portion 22-2 are ±5mm of the outer diameter of the second vertical tube 12.

[0027] Furthermore, the first vertical pipe 11 and the second vertical pipe 12 use the same pipe body, and the first horizontal pipe 21 and the second horizontal pipe 22 use the same pipe body.

[0028] Example 2

[0029] Please refer to Figure 4 Preferably, since the first horizontal tube 21 and the second horizontal tube 22 are relatively long, resulting in a wide movable guardrail, a third vertical tube 31 is connected at the middle of the first horizontal tube 21 and the second horizontal tube 22 to achieve better support. The two ends of the third vertical tube 31 are respectively connected to the inner sides of the first horizontal tube 21 and the second horizontal tube 22. The two ends of the third vertical tube 31 are respectively provided with a first flat portion 31-1 and a second flat portion 31-2. The third vertical tube 31 can also be made of a hollow metal tube, with pressure applied to its symmetrical side walls at both ends to flatten it. The flattened length of the first flat portion 31-1 is ±5mm of the outer diameter of the first horizontal tube 21, and the flattened length of the second flat portion 31-2 is ±5mm of the outer diameter of the second horizontal tube 22.

[0030] In the above embodiments, pressure is applied to the two symmetrical side walls of the first horizontal tube 21, the second horizontal tube 22, and the third vertical tube 31 at both ends to flatten them. They can be processed by existing pressing equipment or flattened into the required flat structure by using a hammer.

[0031] Please refer to Figures 1 to 5The innovation of this technical solution lies in the fact that each end of the first horizontal tube 21 and the second horizontal tube 22 constituting the rectangular frame is designed with a left first flat part 21-1, a left second flat part 22-1, and a right first flat part 21-2 and a right second flat part 22-2. During stacking, from bottom to top, the bottom side wall of the first vertical tube 11 of the second movable guardrail structure presses against the left first flat part 21-1 and the left second flat part 22-1 of the first movable guardrail structure; the bottom of the right first flat part 21-2 and the right second flat part 22-2 of the second movable guardrail structure presses against the upper side wall of the second vertical tube 12 of the first movable guardrail structure; the first horizontal tube 21 of the second movable guardrail structure presses against the outside of the first horizontal tube 21 of the first movable guardrail structure; and the second horizontal tube 22 of the second movable guardrail structure is submerged below the inside of the second horizontal tube 22 of the first movable guardrail structure. When stacking the third movable guardrail structure, the bottom of the left first flat portion 21-1 and the left second flat portion 22-1 of the third movable guardrail structure presses against the upper side wall of the first vertical tube 11 of the second movable guardrail structure, while the bottom side wall of the second vertical tube 12 of the third movable guardrail structure presses against the right first flat portion 21-2 and the right second flat portion 22-2 of the second movable guardrail structure. The first horizontal tube 21 of the third movable guardrail structure presses against the inner side of the first horizontal tube 21 of the second movable guardrail structure, and the second horizontal tube 22 of the third movable guardrail structure is lower than the outer side of the second horizontal tube 22 of the second movable guardrail structure. If the movable guardrail structure has a third vertical tube 31 in the middle, then the first flat portion 31-1 of the first horizontal tube 21 of the stacked second movable guardrail structure presses against the first horizontal tube 21 of the first movable guardrail structure, and the bottom of the second horizontal tube 22 of the second movable guardrail structure is supported on the middle second flat portion 31-2 of the first movable guardrail structure. When the third movable guardrail structure is stacked on top of the second movable guardrail structure, the second flat part 31-2 of the third movable guardrail structure presses on the second horizontal tube 22 of the second movable guardrail structure, and the bottom of the first horizontal tube 21 of the third movable guardrail structure is supported on the first flat part of the second movable guardrail structure.

[0032] Following this pattern of stacking, compared to the vertical stacking of pipes of the same diameter in a rectangular frame, the height formed by stacking the same number of movable guardrail structures in this scheme is less than the height formed by vertically stacking pipes of the same diameter (e.g., ...). Figure 3 As shown in a), therefore, the improved movable guardrail structure of this solution forms symmetrical concave areas on the flat surfaces of the left first flat part 21-1, the right first flat part 21-2, the left second flat part 22-1, the right second flat part 22-2, the middle first flat part 31-1, and the middle second flat part 32-2, making the stacking more compact, saving space, and helping to save transportation and storage costs.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
