Description

Technical Field

[0001] The utility model relates to the field of scaffold safety guardrails, in particular to a buckle scaffold safety guardrail. Background Art

[0002] In the traditional construction industry, the buckle scaffolding is widely used in various construction projects as an efficient and convenient temporary support structure.

[0003] In the design of the buckle scaffolding guardrail, the commonly used method is to directly install horizontal cross bars to provide support. The two ends of these cross bars are welded with buckle joints, which can be buckled with the vertical bars to form an integral guardrail structure. The material of these horizontal bars is generally Q235, with a pipe diameter of φ48.3mm and a wall thickness of 2.5mm. Although this design can meet the basic functions of the guardrail, it also has certain shortcomings.

[0004] First, the load-bearing capacity of the horizontal rod is much higher than the load-bearing capacity required by the guardrail, which leads to a waste of materials. At the same time, in actual construction, the main function of the guardrail is to prevent falls and protect the safety of workers, and it does not require such a high load-bearing capacity. Therefore, the use of high-load-bearing capacity materials and structures actually increases construction costs and resource consumption. Secondly, the overly strong guardrail design also increases the difficulty of installation and disassembly to a certain extent. Due to the large weight and size of the horizontal rod, workers need to spend more manpower and time when installing and disassembling, which affects construction efficiency. How to invent a buckle scaffolding safety guardrail to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a buckle scaffolding safety guardrail, which aims to improve the problem that high-bearing-capacity materials increase construction costs and resource consumption, and secondly increase the difficulty of installation and disassembly, affecting construction efficiency.

[0009] In a preferred technical solution of the present invention, side limiting holes are respectively opened on both sides of the two ends of the railing, and the side limiting holes are inserted into the two sides of the buckle.

[0010] In a preferred technical solution of the present invention, the middle portion of the railing is hollow, and the four corners of the outer wall of the railing are all arc-shaped.

[0011] In a preferred technical solution of the present invention, fitting grooves are provided at both ends of the railing, and the fitting grooves are respectively located outside the upper limit hole and the lower limit hole, and the fitting grooves are arranged corresponding to the outer wall of the upright.

[0012] In a preferred technical solution of the present invention, the side limit hole near the end of the railing passes through the railing, and the side limit hole passes through a corner of the end of the railing to open a guide groove, and the guide grooves are all arc-shaped.

[0013] In a preferred technical solution of the present invention, a limiting protrusion is provided on the outer side of the top of the pin rod, and the limiting protrusion is arranged in a right-angled trapezoid. The right-angled side of the limiting protrusion is aligned with the top of the pin rod, and the bottom of the inclined side of the limiting protrusion is in limiting contact with the inner wall of the upper limit hole.

[0014] In a preferred technical solution of the present invention, a limit pin hole is provided at the bottom of the pin rod, and the limit pin hole is located below the lower limit hole.

The pin 221 quickly connects the railing 211 and the buckle 130 of the vertical pole 110, which is convenient for quick installation and disassembly of the railing 211. At the same time, the railing 211 facilitates protection of workers.

[0027] See also Figure 3 and Figure 4 Upper limit holes 212 are respectively formed at the top of each end of the railing 211, and lower limit holes 213 are respectively formed at the bottom of each end of the railing 211. The railing 211 passes through the upper limit holes 212 and the lower limit holes 213. Side limit holes 214 are respectively formed on both sides of the railing 211, and the side limit holes 214 are inserted into the sides of the buckle 130. The middle part of the railing 211 is hollow, and the four corners of the outer wall of the railing 211 are curved. The inner dimensions of the side limit holes 214 are slightly larger than the dimensions of the buckle 130.

[0028] Both ends of the railing 211 are provided with fitting grooves 215, located outside the upper and lower retaining holes 212 and 213, respectively. These grooves 215 correspond to the outer wall of the upright 110, facilitating a fit with the outer wall of the upright 110 and increasing stability. A side retaining hole 214, located near the end of the railing 211, penetrates the railing 211. A guide groove 216 is provided at a corner of the end of the side retaining hole 214. These guide grooves 216 are arc-shaped and serve to increase the size of the opening of the side retaining hole 214, facilitating insertion of the side retaining hole 214 into the sides of the buckle 130.

[0029] A limiting protrusion 222 is provided on the outer side of the top of the pin 221.

The guide groove 216 is convenient for guiding when the railing 211 is inserted to increase the opening size of the end of the side limit hole 214, and at the same time avoid the inner wall size of the side limit hole 214 being too large, which causes unstable clamping with the buckle 130. At this time, the railing 211 is inserted into the upper limit hole 212, passes through the buckle 130, and comes out from the bottom of the lower limit hole 213. At this time, the limit protrusion 222 abuts against the inner wall of the upper limit hole 212 and the limit protrusion 222 is located above the upper limit hole 212. A pin can be inserted into the limit pin hole 223 to prevent the pin rod 221 from falling off.
