[0024] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0025] See also Figures 1 to 6 As shown, according to an embodiment of the present application, a guardrail fixing structure is provided, comprising: an embedded sleeve 1, a first sealing member 2, a second sealing member 3 and a guardrail body 4;

[0026] Both ends of the embedded sleeve 1 are open structures, the first seal 2 and the second seal 3 are respectively arranged at both ends of the embedded sleeve 1, and the guardrail body 4 is detachably connected to the embedded sleeve 1.

[0027] Specifically, before pouring concrete, the first sealing member 2 is pasted to the bottom of the embedded sleeve 1 by means of structural adhesive, so that it seals the bottom of the embedded sleeve 1 to prevent cement slurry from entering the embedded sleeve 1 during pouring. A plurality of embedded sleeves 1 are respectively embedded at designated positions, and then the second sealing member 3 is installed on the top of the embedded sleeve 1 to seal the top of the embedded sleeve 1 to prevent concrete from entering the embedded sleeve 1 during pouring. After the concrete is poured and hardened, the second sealing member 3 is removed from the top of the embedded sleeve 1, and the guardrail body 4 is installed. It is installed on the embedded sleeve 1 to form an installation and fixation of the guardrail body 4. Compared with the prior art of installing the guardrail body 4 through expansion bolts, the present application removes the second sealing member 3 from the top of the embedded sleeve 1, and then the guardrail body 4 can be threadedly connected and installed with the embedded sleeve 1. No other connecting parts are required during the installation and connection process, which makes its installation and disassembly more convenient, with high installation efficiency, and can save staff working time. The device can be widely used in foundation pits, floors, sump pits, stairwells, roofs and other edges, and has a wide range of applications.

[0028] Positioning ribs 5 are arranged on both sides of the outer circumference of the embedded sleeve 1.

[0029] Specifically, the positioning ribs 5 are welded on both sides of the outer circumference of the embedded sleeve 1. When the embedded sleeve 1 is placed at the specified position before pouring concrete, the positioning ribs 5 are connected and fixed to the longitudinal force-bearing steel bars on the beam by tying wire, which can achieve a more stable fixation of the embedded sleeve 1, improve the stability of the fixation of the embedded sleeve 1 during concrete pouring, maintain its vertical placement, and facilitate subsequent connection and installation.

[0030] Among them, the positioning reinforcement 5 is a threaded steel bar, and its length is greater than the diameter of the embedded sleeve 1, which is more convenient to fix to the longitudinal force-bearing steel bars on the beam by tying wire.

[0031] The positioning ribs 5 are arranged horizontally.

[0032] Specifically, the positioning ribs 5 are horizontally welded on both sides of the outer circumference of the embedded sleeve 1. Through its horizontal setting, the positioning ribs 5 are parallel to the longitudinal stress-bearing steel bars on the beam, which facilitates the positioning ribs 5 to fit the longitudinal stress-bearing steel bars on the beam and connect and fix the two.

[0033] The second sealing member 3 includes a plug 31 and a sealing plate 32 . The bottom of the plug 31 is threadably connected to the inner portion of the embedded sleeve 1 , and the sealing plate 32 is disposed on the top of the plug 31 .

[0034] Specifically, the second sealing member 3 is installed on the embedded sleeve 1 and is used to seal the top of the embedded sleeve 1. It includes a plug 31 and a sealing plate 32. The plug 31 is a tubular structure with an external thread on the outer circumference of the bottom and an internal thread inside the embedded sleeve 1. The bottom of the plug 31 can be threadedly installed inside the embedded sleeve 1, and the sealing plate 32 is adhered to the top of the plug 31 by structural adhesive. During concrete pouring, the second sealing member 3 can seal the top of the embedded sleeve 1, and the top of the plug 31 is located above the poured concrete, which is convenient for disassembly of the plug 31. After disassembly of the plug 31, the interior of the embedded sleeve 1 can be exposed, which is convenient for connecting and installing the guardrail body 4 therewith.

[0035] The plug 31 is a steel pipe, and a thread is provided on the outer wall of the bottom thereof so as to enable it to be installed and removed from the interior of the embedded sleeve 1 .

[0036] The guardrail body 4 includes a main vertical pole 41 and a horizontal pole 42 . The horizontal pole 42 is horizontally arranged on the main vertical pole 41 . The main vertical pole 41 is threadedly connected to the inside of the embedded sleeve 1 .

[0037] Specifically, the guardrail body 4 includes several main vertical poles 41 connected to the embedded sleeve 1. After the plug 31 is removed from the embedded sleeve 1, the interior of the embedded sleeve 1 can be exposed, and the bottom of the main vertical pole 41 is connected to the interior of the embedded sleeve 1 in a spiral manner to achieve the installation of the main vertical pole 41. After several main vertical poles 41 are installed, the horizontal rod 42 is horizontally installed on the several main vertical poles 41 to achieve safer protection. The installation and disassembly of the guardrail body 4 is more convenient.

[0038] A steel pipe buckle is provided between the horizontal rod 42 and the main vertical rod 41 .

[0039] Specifically, the horizontal rod 42 is fixedly mounted on the main vertical rod 41 through a steel pipe buckle, and the steel pipe buckle can be a cross steel pipe buckle or a rotating fastener.

[0040] The first sealing member 2 is a stopper plate, and the diameter of the first sealing member 2 is the same as the outer diameter of the embedded sleeve 1 .

[0041] Specifically, the first sealing member 2 is a stop plate, which is made of a steel plate and has a circular structure. The diameter of the first sealing member 2 is the same as the outer diameter of the embedded sleeve 1. The first sealing member 2 is installed at the bottom of the embedded sleeve 1 by means of structural adhesive. After drying, the bottom of the embedded sleeve 1 can be sealed, and the slurry during concrete pouring can be prevented from entering from the bottom of the embedded sleeve 1.

[0042] The blocking plate 32 is a stop plate, and the diameter of the blocking plate 32 is not less than the outer diameter of the plug 31 .

[0043] Specifically, the blocking plate 32 is also a stop plate, and the diameter of the blocking plate 32 is not less than the outer diameter of the plug 31. The blocking plate 32 is also installed on the top of the plug 31 by structural adhesive to achieve sealing of the top of the plug 31, preventing concrete from entering the embedded sleeve 1 from the top during pouring, thereby facilitating the subsequent installation of the main pole 41.

[0044] The positioning rib 5 is connected to the outer circumference of the embedded sleeve 1 by welding.
