Description

Technical Field

[0001] The utility model belongs to the technical field of building guardrails, in particular to a temporary guardrail for a horizontal opening on a floor of a civil building. Background Art

[0002] In the construction of civil buildings, when the reinforced concrete main frame of each floor is completed, the horizontal openings of the floors have no structural enclosures. Accidents such as people and objects falling are prone to occur in the horizontal openings of the floors, and temporary protection must be provided for the horizontal openings of the floors. However, in the construction process of civil buildings, the demand for guardrails is very large, and the guardrails need to be frequently installed and disassembled, which is very time-consuming; and the existing guardrails are fixed by welding, bolts and nuts, so when they are dismantled, destructive dismantling or more tools are required, which has a certain technical threshold for ordinary workers. There is a problem of loss of bolts and nuts when disassembling the connecting parts, and there will be loss each time they are reused, which is not conducive to repeated recycling. In order to solve the above technical problems, this application document provides a temporary guardrail for the horizontal openings of the floors of civil buildings. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment one:

[0028] See also Figure 1-6 As shown, the utility model is a temporary guardrail for horizontal openings on floors of civil buildings, comprising a guardrail pile 1, a guardrail grille 2 and a diagonal brace 3. The guardrail pile 1 comprises a base 11. A rectangular column 12 is fixed to the middle of the upper surface of the base 11. Three consecutive side surfaces of the rectangular column 12 are respectively provided with a slot 13 that matches the guardrail grille 2. A pin rod 14 is fixed to the inner side of the three slots 13 on the upper surface of the base 11. A pin hole that matches the pin rod 14 is respectively provided on the bottom surface of the two ends of the guardrail grille 2. Two pairs of cylindrical rods 15 are fixed to the upper surface of the base 11. The diagonal brace 3 is installed on one or two cylindrical rods 15. Four cylindrical rods 15 on a guardrail pile 1 can be respectively installed with a diagonal brace 3.

[0029] The diagonal brace 3 specifically includes two round tubes 31 that cooperate with the cylindrical rod 15, and the distance between the axes of the two round tubes 31 is the same as the distance between the axes of a pair of cylindrical rods 15. The two round tubes 31 are connected as a whole through a fixing plate 32. A handle bolt 33 is threaded through and connected to the two round tubes 31. A diagonal brace rod 34 that is set obliquely downward is fixed on one side of the fixing plate 32. A supporting foot 35 is fixed at the lower end of the diagonal brace rod 34. The round tube 31 on the diagonal brace 3 is sleeved on the cylindrical rod 15 on the guardrail pile 1, and the guardrail pile 1 is supported to a vertical state. The supporting foot 35 of the diagonal brace 3 is naturally grounded, and then the pair of handle bolts 33 are tightened, and the diagonal brace 3 is fixed to the relative position of the guardrail pile 1, that is, the straightening support of the guardrail pile 1 is completed. At most four diagonal braces 3 can be installed on one guardrail pile 1, and the support positioning and adjustment of the guardrail pile 1 are fast. The guardrail pile 1 can be suspended in an uneven position, and the diagonal braces 3 are easy to install and disassemble.

[0030] The temporary protective fence of this year's utility model consists of three independent components: guardrail base piles 1, guardrail grille 2 and diagonal braces 3. No other components and tools are required for installation. The installation difficulty is low and there is no technical threshold for ordinary workers. The installation is quick and efficient, the maintenance cost is low, and it is suitable for popularization and use.

[0031] The guardrail grille 2 includes a rectangular frame 21. A metal mesh 22 is installed inside the rectangular frame 21. Bevels 23 are provided at the corners of both sides of the rectangular frame 21. The rectangular frame 21 forms a stable outer frame. The metal mesh 22 is light-transmissive while playing a protective role, making it convenient to observe the environment behind it. A circle of reflective stickers 24 is pasted on the surface of the rectangular frame 21. The reflective stickers 24 increase the conspicuity of the guardrail grille 2 and reduce the probability of hitting the guardrail grille 2 in a light environment.

[0032] In order to prevent the guardrail grille 2 from being disengaged from the slots 13 and the pins 14 on the guardrail pile 1 after being stressed, a spring pin 16 is embedded and fixed on one side wall of the upper ends of the three slots 13. When disassembling the guardrail grille 2, the telescopic end of the spring pin 16 is pressed inwards and recovered, and the guardrail grille 2 is pulled up to disengage the guardrail grille 2 from the pins 14, and then can be directly taken out of the slots 13.
