Usually, in order to demarcate the construction area and ensure the safety of personnel, guardrails are arranged at the construction site. However, most traditional guardrails are of an integral structure, and this one-piece design has obvious drawbacks during transportation. Due to its non-detachable and non-foldable nature, it occupies a large amount of space, bringing great restrictions to the loading of transport vehicles, not only increasing the transportation cost but also reducing the transportation efficiency. At the same time, during the handling process, due to its large volume and heavy weight, it requires a lot of manpower and material resources, and the operation is extremely inconvenient, seriously affecting the progress and efficiency of the pre-construction preparation work. Therefore, how to improve the structure of the guardrail to make it more convenient for transportation and handling has become an urgent problem to be solved in the field of civil engineering construction guardrails.

A warning light 9 is provided at the top of the column 1, and the warning light 9 is powered by a built-in battery. A fixed base 3 is provided at the bottom of the column 1. The cross bar 2 is horizontally arranged between the two columns 1. A connection groove 4 is provided on the side of the column 1. A connector 5 adapted to the connection groove 4 is provided at the end of the cross bar 2. The connector 5 is inserted into the connection groove 4 in a matching manner to achieve the detachable connection between the cross bar 2 and the column 1. An elastic clamping member 6 is provided on the inner wall of the connection groove 4. A card slot 7 cooperating with the elastic clamping member 6 is provided on the connector 5. When the connector 5 is inserted into the connection groove 4, the elastic clamping member 6 is snapped into the card slot 7 to fix the cross bar 2.

[0026] A protective net 11 is also provided between the two columns 1, and the upper and lower edges of the protective net 11 are fixedly connected to the cross bar 2 through connecting pieces. The connecting piece includes a hook 12 fixedly arranged on the cross bar 2 and a hanging ring 13 fixedly arranged on the edge of the protective net 11, and the hanging ring 13 is matched and hooked with the hook 12.

[0028] The working principle of a spliced guardrail for civil engineering construction of the present utility model is as follows: The spliced guardrail for civil engineering construction mainly realizes the stable connection between the cross bar 2 and the column 1 through the insertion fit of the connection head 5 at the end of the cross bar 2 and the connection groove 4 on the side of the column 1, and the clamping connection between the elastic clamping member 6 on the inner wall of the connection groove 4 and the clamping groove 7 on the connection head 5. At the same time, the protective net 11 is hooked through the hook 12 on the cross bar 2 and the hanging ring 13 on the edge of the protective net 11, and is kept in a taut state by means of the tension spring 14 to provide effective protection. The warning light 9 at the top of the column 1 is powered by a built-in battery and provides a warning function when needed.

[0029] The using process of a spliced guardrail for civil engineering construction of the present utility model is as follows:

[0030] 1. Preparation work: Place the two columns 1 at the predetermined construction position through the fixed bases 3 at the bottom to ensure that the columns 1 are vertical and stable. Check whether the connection head 5 of the cross bar 2 and the connection groove 4 of the column 1 are intact to ensure that the elastic clamping member 6 and the clamping groove 7 are normal. Prepare the protective net 11 to ensure that the hanging ring 12 and the tension spring 14 are not damaged.

[0031] 2. Install the cross bar: Align the connection head 5 at one end of the cross bar 2 with the connection groove 4 on the side of the column 1 and insert it. During the insertion process, the connection head 5 squeezes the clamping ball 16 of the elastic clamping member 6, so that the clamping ball 16 compresses the spring 18 and retracts into the cavity 15. When the connection head 5 is completely inserted into the connection groove 4, the clamping ball 16 is clamped into the clamping groove 7 on the connection head 4 under the action of the spring 18 to realize the fixed connection between the cross bar 2 and the column 1. Repeat the above steps to install the other cross bar 2 between the bottoms of the columns 1.

[0032] 3. Install the protective net: Hang the hanging ring 13 on the upper edge of the protective net 11 on the hook 12 on the crossbar 2. In the same way, hang the hanging ring on the lower edge of the protective net on the hook of the lower crossbar. Due to the action of the tension spring 14, the protective net 11 will remain in a taut state, providing a good protective effect.

[0033] 4. Turn on the warning light: In the night or in low visibility conditions, turn on the switch of the warning light 9 at the top of the column to make it start working and provide warnings for the construction site.

[0034] 5. Disassembly and maintenance: When the guardrail needs to be disassembled, first remove the protective net 11, then push the crossbar 2 upward, and under the action of external force, make the snap ball 16 retract into the cavity 15 until it disengages from the card slot 7, so as to pull out the crossbar 2 for disassembly. Regularly check each component of the guardrail, such as whether the connection parts are loose, whether the protective net is damaged, whether the warning light is working properly, etc. If there are problems, carry out maintenance and replacement in time.

[0035] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and without departing from the purpose of the creation of the present utility model, without creative design, structures and embodiments similar to this technical solution are all within the protection scope of the present utility model.
