[0041] In actual use, since the assembled building guardrail is detachable, a larger assembled building guardrail can be disassembled into multiple smaller parts, and the same parts can be placed together, which not only reduces the storage space occupied, but also facilitates transportation and installation. After these disassembled parts are transported to the designated location, the two ends of the barrier assembly 22 are respectively connected to the two first rod bodies 21 to form a guardrail unit 2, and the two adjacent guardrail units 2 are connected through the two first connecting parts 3 on the connecting member 1. Since there are multiple first connecting parts 3, the splicing angle between the two adjacent guardrail units 2 can be changed by connecting the guardrail unit 2 to different first connecting parts 3, so as to be more adaptable. A construction site with a complex environment; since the barrier assembly 22 is rotatably connected to the first rod body 21, the two first rod bodies 21 can move relative to each other in the vertical direction, so that the two connecting pieces 1 at the bottom of each guardrail unit 2 after assembly can abut against the ground, thereby adjusting the relative positions between the multiple guardrail units 2, and making the structure of the assembled building guardrail more stable after the final assembly; in addition, multiple guardrail units 2 can be connected to the first connecting piece 1 to form intervals in multiple directions, which can be suitable for a variety of construction environments and has a wider range of applications; in general, by using the assembled building guardrail, it can be disassembled and assembled, the splicing angle and relative position can be adjusted, and intervals in multiple directions can be divided at the same time.

[0042] See attached Figure 2 , Attachment Figure 5 and attached Figure 6 , the specific structure of the connector 1 and the connection method between the connector 1 and the first rod body are not limited in the present application, and can be flexibly selected according to actual needs. One of the structures is introduced in this embodiment. Specifically, the upper part of the first rod body 21 is provided with a second matching portion 6, and the first matching portion 5 is located at the lower part of the first rod body 21; the connector 1 includes a base 101, a support member 102, and a fixing block 103. The bottom of the base 101 abuts the ground for support and fixing. A plurality of first connecting portions 3 are all arranged on the base 101, and the first rod body 21 and the base 101 are detachably connected through the first matching portion 5 and the first connecting portion 3; the support member 102 is vertically arranged, and the bottom of the support member 102 is connected to the base 101 and is located at the center of the plurality of connecting portions; the fixing block 103 is located at the top of the support member 102, and a plurality of second connecting portions 4 are provided on the fixing block 103. The plurality of second connecting portions 4 are all located in the same plane and arranged in a circular array, and the first rod body 21 and the fixing block 103 are detachably connected through the second matching portion 6 and the second connecting portion 4.

[0043] Through the design of the above structure, the upper and lower parts of the first rod body 21 can be fixed by the connecting member 1, so that the connection between the connecting member 1 and the guardrail unit 2 is more firm and the structure is more stable. In addition, the support rod 102 can also fill the gap formed between two adjacent guardrail units 2 to prevent people from passing through the above gap.

[0044] It should be noted that the cross-sectional size of the base 101 should be larger to reduce the force per unit area of ​​the base 101, enhance the load-bearing capacity, and prevent tipping; the weight of the base 101 should be heavier so that the center of gravity of the assembled building guardrail is located at the bottom, making it more stable after placement, and also having a certain degree of anti-tip function.

[0045] See attached Figure 3 and attached Figure 6 In order to more clearly introduce the connection method and structure of the first rod body 21 and the connecting member 1, the following design is carried out in this embodiment. Specifically, the first connecting part 3 is a slot with a connecting hole 31 on the side, the second connecting part 4 is a guide hole, the first matching part 5 is a threaded hole, and the second matching part 6 is a guide rod with an extension plate 61. The connecting hole 31 and the threaded hole correspond to each other and are arranged horizontally, so that the first rod body 21 can be inserted into the slot, and the first rod body 21 and the base 101 are connected and fixed by a threaded connection. The guide hole and the guide rod correspond to each other and are arranged vertically, so that the guide rod can be inserted into the guide hole, thereby assisting the first rod body 21 to be inserted into the slot.

[0046] Through the design of the above structure, the second matching portion 6 can be first inserted into the second connecting portion 4, that is, the guide rod can be inserted into the guide hole, and then under the guiding action of the above two components, the first rod body 21 can be assisted to be inserted into the first connecting portion 3, that is, the first rod body 21 is inserted into the slot. At this time, the first matching portion 5 and the first connecting portion 3 can be connected and fixed by threaded matching, that is, the threaded section of the locking bolt passes through the connecting hole 31 and is screwed into the threaded hole. At this time, the upper part of the first rod body 21 can be fixed on the fixing block 103 through the action of the second matching portion 6 and the second connecting portion 4, and the lower part of the first rod body 21 can be fixed on the base 101 through the action of the first matching portion 5 and the first connecting portion 3.

[0047] See attached Figure 1 , Attachment Figure 2 and attached Figure 4 Some guardrails on the market can rotate with each other after being connected. Although the angle between two adjacent guardrails can be adjusted, multiple intervals cannot be formed. At the same time, the positions between them are easy to change, and they are not stable enough after being placed. In order to solve the problem that the guardrails are easy to move back and forth in the above problem, the following design is carried out in this embodiment. Specifically, the cross-section of the first rod body 21 is non-circular to prevent the first rod body 21 and the base 101 from rotating with each other.

[0048] Furthermore, in order to facilitate the assembly of various components, the following design is also carried out in this embodiment. Specifically, the bottom of the first rod body 21 and the bottom of the guide rod are both provided with a first chamfer for guidance during assembly.

[0049] Furthermore, in order to prevent construction workers from being injured by sharp edges when assembling the guardrail, the following design is carried out in this embodiment. Specifically, the side and top of the first rod body 21 are provided with a second chamfer to remove the sharp edges; in addition, the connecting hole 31 is set as a countersunk hole to keep the side of the base 101 flat and more beautiful, and a rubber plug can be provided at the countersunk hole to provide certain protection for the components in the connecting hole 31, such as rain and dust protection.

[0050] See attached Figure 4 , Attachment Figure 5 and attached Figure 7-10 There are many structures that can play a barrier effect. This embodiment introduces one of the structures. Specifically, the barrier assembly 22 includes a second rod body 221, a third rod body 222, and a plurality of fourth rod bodies 223. The opposite ends of the second rod body 221 are respectively connected to the two first rod bodies 21 in the same guardrail unit 2 in a vertical plane so that the second rod body 221 can rotate in the vertical plane; the third rod body 222 and the second rod body 221 are equal in length and parallel to each other. The third rod body 222 is located at the second rod body 22 1, opposite ends of the third rod body 222 are respectively connected to the two first rod bodies 21 in the same guardrail unit 2 for rotation in the vertical plane, so that the third rod body 222 can rotate in the vertical plane; a plurality of fourth rod bodies 223 are vertically arranged and linearly arranged along the direction of the second rod body 221, and the top of each fourth rod body 223 is connected to the second rod body 221 for rotation in the vertical plane, and the bottom is connected to the third rod body 222 for rotation in the vertical plane, so as to prevent the rotation of the second rod body 221 and the third rod body 222 from being hindered.

[0051] Through the design of the above structure, a barrier can be formed by the second rod body 221, the third rod body 222, and multiple fourth rod bodies 223, and the multiple low rod bodies 223 will not hinder the rotation of the second rod body 221 and the third rod body 222, so that the two first rod bodies 21 in the same guardrail unit 2 can move up and down according to the height of the ground and are always parallel to each other during the movement, so that the bottom of the connecting member 1 can always be in contact with the ground.

[0052] See attached Figure 6 and attached Figure 7, the existing assembled guardrails on the market often require the cooperation of multiple people when installing structures similar to the barrier assembly 22, such as one person lifting and supporting, and another person connecting the corresponding parts, which is time-consuming and laborious. In order to solve the above problems, the following design is carried out in this embodiment. Specifically, a first connecting seat 7 is provided on the upper part of the first rod body 21, and a second connecting seat 8 is provided on the lower part. The opposite ends of the second rod body 221 are provided with a horizontal rotation axis 9, and the opposite ends of the third rod body 222 are provided with a horizontal rotation hole 10. The first connecting seat 7 is provided with a horizontal first through hole 71, and the second connecting seat 8 is provided with a horizontal second through hole 81. The first connecting seat 7 is also provided with a vertical through groove 72, and the through groove 72 is connected to the first through hole 71 so that the rotation axis 9 can pass through the through groove 72 and move into the first through hole 71. Bolts 11 are provided in the rotation hole 10 and the second through hole 81 to prevent the second rod body 221 and the first rod body 21 from separating from each other during the mutual rotation process.

[0053] Through the design of the above structure, the second rod body 221 is directly placed on the first connecting seat 7 through the rotating shaft, and then the third rod body 222 is connected to the second connecting seat 8. No additional personnel assistance is required during the whole process, and a single person can easily complete the assembly operation without manual positioning. After the second rod body 221 is placed, the rotating holes 10 at both ends of the third rod body 222 will automatically align with the second through holes 81 on the second connecting seat 8. The installation is convenient and quick, saving time and effort.

[0054] In order to adapt to various complex construction environments, such as some construction environments requiring guardrails to have a certain degree of corrosion resistance, some construction environments requiring guardrails to be light and easy to move, and some construction environments requiring guardrails to have good stability, etc., in order to solve the above problems, the following design is carried out in this embodiment. Specifically, the material of the connecting member 1 and the guardrail unit 2 are both one of zinc steel, stainless steel, aluminum alloy, and plastic. The center of gravity of the assembled building guardrail formed by the connecting member 1 and the guardrail unit 2 is located at the bottom to ensure the stability of the assembled building guardrail.

[0055] Through the design of the above structure, different materials can be selected to manufacture the assembled building guardrail according to different construction environments, and the application range is wider.

[0056] With the continuous advancement of technology, night construction has become more and more common. In order to prevent construction workers or various equipment from colliding with the assembled building guardrail during movement, the following design is carried out in this embodiment. Specifically, a reflective coating is provided on the guardrail unit 2 to reflect the surrounding light to serve as a warning.
