Description

Technical Field

[0001] The present application relates to the technical field of building guardrails, and in particular to an assembled building guardrail. Background Art

[0002] Building guardrails are structures used to define and protect buildings, sites or areas. They can be used for a variety of purposes, including safety, aesthetics, isolation and traffic guidance. During construction, guardrails are usually required to separate the construction area.

[0003] As disclosed in Chinese Patent Publication No. (CN212958008U), an assembled building guardrail includes a first support column, a horizontal rail, a vertical rail and a mounting sleeve, a second support column is arranged on one side of the first support column, and the bottom ends of the first support column and the second support column are fixed with a shock-absorbing base, four corners of the bottom of the shock-absorbing base are fixed with fixing piles, and barbs are evenly distributed on the fixing piles, both ends of both sides of the first support column and the second support column are fixed with mounting clips, and both ends between the first support column and the second support column are provided with horizontal rails, both ends of the horizontal rails are connected to the mounting clips by fixing bolts, and vertical rails are evenly arranged between the horizontal rails, the utility model is convenient for installation and disassembly of the building guardrail by installing the first support column, the second support column, the mounting clips, the fixing bolts, the horizontal rails, the vertical rails, the mounting sleeves, the grooves, the reset springs, the reserved holes and the pressing beads, so as to facilitate replacement when a single vertical rail is damaged.

[0004] However, as in the above-mentioned patent, there is still a problem of poor durability in the assembly and use of the building guardrail. For example, in the above-mentioned patent, the pressing bead is pushed out by the telescopic force of the return spring and stuck in the reserved hole, thereby fixing the vertical railing with the mounting sleeve. However, this method mainly relies on the elastic force of the support spring as the supporting force to ensure the firm connection between the guardrail components, and the return spring is a mechanical part. Long-term use and the influence of the external building environment may cause its elastic performance to decline or be damaged, thereby affecting the stability and safety of the guardrail. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application provides an assembled building guardrail, which has the advantages of high durability in assembly and use, and solves the problem of poor durability in assembly and use of building guardrails in the prior art.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an assembled building guardrail, comprising two guardrail posts, an assembly mechanism is provided between opposite sides of the two guardrail posts, and a combination mechanism is provided on the left and right sides of the guardrail;

[0007] The assembly mechanism includes two horizontal bars, a plurality of assembly seats, an elastic connection sleeve, an assembly screw, a threaded sleeve, an anti-slip sleeve, a vertical rod and a fixing piece. The two horizontal bars are slidably connected between opposite sides of two guardrail posts. The plurality of assembly seats are respectively fixed to opposite sides of the two horizontal bars. The elastic connection sleeve is fixed to a side of the assembly seat away from the horizontal bar. The assembly screw is slidably connected to the inner wall of the elastic connection sleeve. The threaded sleeve is threadedly connected to the outer side of the assembly screw. The anti-slip sleeve is fixed to a side of the threaded sleeve relative to the assembly seat.

[0013] Furthermore, a rotating handle is fixed to the outer side of the threaded sleeve, and the cross-sectional shape of the elastic connecting sleeve is C-shaped.

[0014] By adopting this technical solution, the elastic connecting sleeve is C-shaped and its front notch can facilitate the assembly screw to be inserted into it, so as to facilitate the disassembly and assembly of a single vertical rod after the assembly between the horizontal rail and the guardrail column.

[0015] Furthermore, limit rings are fixed on both upper and lower sides of the outer surface of the vertical rod, and the diameter of the limit ring is greater than the diameter of the threaded sleeve.

[0016] By adopting this technical solution, the limiting ring can prevent the threaded sleeve from falling off from the vertical rod.

[0020] By adopting this technical solution, the opening and closing angles of adjacent guardrails can be adjusted by rotating the combined arms in a circle along the rotating pins, so that guardrail nets of different sizes can be combined according to needs.

[0021] Furthermore, a rotating lever is fixed to both the left and right sides of the locking nut.

[0022] By adopting this technical solution, the locking nut and the locking stud can be threadedly connected after the adjustment combination, and then the locking nut is driven by the rotating lever to tighten along the locking stud to abut the docking sleeve, applying pressure to it to prevent it from rotating freely, thereby achieving the effect of a free locking adjustment combination.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

After the assembly screw 24 is respectively inserted into the two elastic connecting sleeves 23, the user turns the rotating handle 29 to drive the threaded sleeve 25 to rotate upward along the outer side of the assembly screw 24, and then pushes the anti-drop sleeve 26 to be inserted into the outer side of the elastic connecting sleeve 23, so as to block the notch position of the elastic connecting sleeve 23, avoid separation between the vertical rod 27 and the elastic connecting sleeve 23, and realize rapid assembly. When the guardrail is damaged, it can be replaced separately according to the damaged position.

[0041] (2) When the building guardrail is used to improve the combination adjustment effect, when the guardrail is used, the combination arms 31 on the multiple guardrails are fitted together to make the positions of the docking sleeves 32 correspond, and then the rotating pin 33 is inserted into the two fitted docking sleeves 32. At this time, the multiple building guardrails can be combined and connected, and the opening and closing angles of adjacent guardrails can be adjusted by rotating the combination arms 31 along the rotating pin 33 in a circle, so as to be combined into combined guardrails of different sizes according to needs. At the same time, after the adjustment combination, the locking nut 35 and the locking stud 34 can be threadedly connected, and then the locking nut 35 can be driven by the rotating lever 36 to tighten along the locking stud 34 to abut the docking sleeve 32, and pressure is applied to it to prevent it from rotating freely, thereby achieving the effect of free locking and adjustment combination.
