Description

Technical Field

[0001] The utility model relates to the technical field of railings for construction projects, in particular to a temporary external wall enclosure railing for construction projects. Background Art

[0002] During the construction of a building project, it is usually necessary to set up temporary guardrails on the outer wall of the construction floor, referred to as fences.

[0003] Edges and openings are the focus of safety protection at construction sites. Setting up fences can prevent construction workers on site from falling from edges and openings, avoiding casualties.

[0004] There are many types and quantities of building guardrails on the market, but the commonly used building guardrails have some disadvantages: 1) They need to be produced in a standardized manner; 2) When installing the railing columns, expansion bolts are generally required to fix them. The installation of expansion bolts requires drilling holes in the structural surface, which will cause certain damage and damage to the structure; 3) After the guardrails are installed, they are not easy to disassemble or move; 4) Standardized fences cannot adapt to the edges of irregular sites.

[0005] Based on the actual safety needs on construction sites, we propose a temporary exterior wall guardrail for building construction. Utility Model Content

[0006] The purpose of the present invention is to solve the deficiencies of the above-mentioned background technology and to provide a temporary guardrail for exterior walls for construction, which solves the drawbacks that exterior wall fences need to be manufactured in a standardized manner, damage the structure during installation and use, are difficult to adjust after installation, and cannot adapt to irregular edges. Compared with existing temporary guardrails for exterior walls, the cost of use is lower, the installation is more convenient, and the angle of the railing can be flexibly adjusted according to the shape of the construction site, thereby eliminating security blind spots and improving the protection effect.

[0009] Furthermore, an oblique rod is obliquely arranged between two adjacent vertical poles, one end of the oblique rod is fixedly connected to the lower part of the vertical pole, and the other end is fixedly connected to the upper part of the vertical pole; according to the floor height, multiple oblique rods can also be arranged between two adjacent vertical poles to further strengthen the guardrail.

[0010] Furthermore, an outer sleeve connection portion is provided at the bottom of the vertical pole, which is used for the upper and lower connection of two vertical poles to achieve a connection combination of vertical poles of the same or different specifications. The vertical poles can be processed into different sizes according to requirements and can be spliced ​​according to different sizes during on-site construction to meet different floor height requirements.

[0011] Furthermore, a plurality of discs are arranged on the vertical rod along its axial direction, a through hole is provided in the center of the disc, cross bar connecting holes and oblique bar connecting holes are arranged in the circumferential direction of the disc, and the cross bar connecting holes and oblique bar connecting holes are arranged alternately in the circumferential direction of the disc.

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] like Figure 1 As shown, a temporary external wall guardrail for construction is arranged between the upper and lower floor slabs, including a vertical pole 1, a horizontal pole 3 and an adjustable top support 2; the adjustable top support 2 is arranged on the upper part of the vertical pole 1, and the two are arranged top to top between the upper and lower floor slabs. By adjusting the relative distance between the adjustable top support 2 and the vertical pole 1, the strength of the top is controlled to prevent the vertical pole 1 from tipping over between the upper and lower floor slabs.

[0032] A plurality of discs 4 are sleeved on the vertical pole 1, and the spacing between the discs 4 is 500 mm. A through hole 401 is provided in the center of the disc 4, and the inner diameter of the through hole 401 matches the outer diameter of the vertical pole 1. Cross bar connecting holes 402 and diagonal bar connecting holes 403 are arranged at intervals in the circumferential direction of the disc 4, that is, the cross bar connecting holes 402 and the diagonal bar connecting holes 403 are arranged alternately.

[0033] Both ends of the cross bar 3 are fixed with latch joints A301, and the cross bar 3 is connected to the cross bar connecting hole 402 of the disc 4 on the vertical pole 1 through the latch joints A301 at both ends.

[0034] like Figure 2 As shown, an outer sleeve connecting portion 101 is provided at the bottom of the vertical pole 1, which is used for the upper and lower connection of two vertical poles 1; for houses with different storeys, vertical poles 1 of different specifications can be connected and used in combination to meet the enclosure requirements; the vertical poles are available in a variety of lengths, and the commonly used specifications are 500mm, 1000mm, 1500mm, 2000mm, 2500mm, and 3000mm.

[0035] Note: The adjustable top support 2 needs to be used in conjunction with the vertical pole 1. The height of the vertical pole 1 needs to be lower than the height of the floor and controlled within 500mm.

[0036] When the building floor height is too high, the combined connection of the vertical pole 1 is not stable enough, and an inclined rod 5 can be installed on the side of the vertical pole 1; pin joints B501 are movably provided at both ends of the inclined rod 5 for connection with the inclined rod connection hole 403 of the disc 4 on the vertical pole 1.

[0037] For super high storey height, a guardrail composed of multiple vertical poles needs to be used with multiple diagonal rods to tighten and prevent it from falling apart and overturning. Multiple diagonal rods 5 can be set between the vertical poles 1 to improve the stability of the railing.

[0038] like Figure 3 As shown, in this embodiment, the crossbar 3 only needs to be connected to the three discs 4 at the lower part of the vertical pole 1 to meet the protection requirements; at the same time, a dense mesh 6 is matched between the three layers of crossbars 3 to improve the protection effect.

[0039] In another embodiment, the discs 4 within the entire height range of the vertical pole 1 can be installed with the crossbar 3 to achieve a fully enclosed protective effect.

[0040] In another embodiment, a footboard 7 may be provided at the bottom of the upright pole 1 after installation to prevent building materials from falling from the bottom.

[0041] In another embodiment, if a locally protruding structure is encountered, the vertical pole 1 can partially offset the position of the vertical pole through cross bars 3 of different specifications, thereby avoiding the locally protruding structure. For this purpose, the cross bars have models of various lengths, and commonly used specifications are 300mm, 600mm, 900mm, 1200mm, 1500mm, 1800mm, 2400mm, and 3000mm.

[0045] 3) Installation of vertical pole 1: Connect the adjustable top support to the top of vertical pole 1, and manually adjust the adjusting nut so that the combined length of vertical pole 1 and the adjustable top support is slightly shorter than the floor height; according to the positioning of the layout, install vertical pole 1 to the designated position, first tighten the adjusting nut to temporarily align vertical pole 1 and the adjustable top support in the current position, and after the verticality is adjusted, use a tool to tighten the adjusting nut again to increase the force of the top.

[0046] 4) Installation of horizontal bar 1: Securely connect the pin joint at one end of horizontal bar 1 to the disc of vertical bar 1, and leave the other end suspended in the air and parallel to the outer wall.

[0047] 5) Installation of the second vertical pole: Connect the adjustable top support to the top of the second vertical pole, and manually adjust the adjusting nut so that the combined length of the second vertical pole and the adjustable top support is slightly shorter than the floor height; connect the disks of the corresponding heights of the first vertical pole and the suspended horizontal bar, and fine-tune the position of the second vertical pole to coincide with the positioning of the line. First, tighten the adjusting nut initially to temporarily align the second vertical pole and the adjustable top support in the current position. After the verticality adjustment is completed, use a tool to finally tighten the adjusting nut to increase the force of the top.

[0048] 6) Subsequent installation: Follow the above steps to continue installing horizontal bar 2, vertical bar 3, ... horizontal bar n-1, vertical bar n.

[0049] 7) Tightening of railings: After all guardrails are installed, further tighten the pin joints connecting the horizontal bars and vertical discs.
