Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, and particularly relates to a prefabricated guardrail for building construction. Background Art

[0002] During building construction, guardrails must be installed around the foundation pit, on the balconies, material platforms and cantilever platforms where railings or parapets have not been installed yet, at the edges of canopies and cornices, and around the roofs and floors without external scaffolding. Traditional guardrails generally adopt two methods. One type of guardrail uses wire mesh sheets and columns fixed by welding through multiple bolts, with a complex assembly process that causes waste of human resources. The other type uses standardized prefabricated guardrails for edge protection. However, the length of this type of guardrail is fixed and cannot meet the protection requirements of different lengths. Moreover, this guardrail is a single integral unit that needs to be transported as a whole and cannot be disassembled and folded. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a prefabricated guardrail for building construction, which solves the problems raised in the current background art.

[0004] To achieve the above object, the utility model provides the following technical solutions:

[0005] A prefabricated guardrail for building construction includes a first support column, a second support column, and a connecting device. The first support column and the second support column are connected by the connecting device. Anti-tipping devices are arranged at the bottoms of the first support column and the second support column. A clamping plate is arranged on one side of the first support column. A plurality of positioning holes are formed on the surface of the clamping plate. A clamping groove is formed on the other side of the second support column. A plurality of through holes are formed on the surface of the second support column. The positions of the positioning holes and the through holes are kept consistent. By inserting a pin into the positioning hole on the clamping plate and the through hole on the second support column, the clamping plate and the second support column are limited and fixed.

[0006] Preferably, the connecting device includes a protective plate. An activity groove is formed on the surface of the protective plate. Symmetric threaded rods are movably connected in the activity groove. Both ends of the threaded rods are threadedly connected with activity shafts. One side of one activity shaft is hinged with a first protective rod. One side of the other activity shaft is hinged with a second protective rod. The first protective rod and the second protective rod are cross-connected by a rotating column. Adjacent protective plates are connected by the first protective rod and the second protective rod.

[0007] Preferably, the anti-tipping device includes a support plate. Symmetric ground cones are arranged at the bottom end of the support plate. A plurality of barbed plates are annularly arranged on the surface of the ground cones.

[0008] Preferably, a fixing plate is provided on the front surface of the support plate. A fixing column is penetrated through the fixing plate. A sliding rod is provided at the upper end inside the fixing column. Symmetric sliders are slidably connected to the sliding rod. Symmetric support rods are rotatably connected to the bottom ends of the symmetric sliders. A moving plate is provided at the top end of the slider. The moving plate is movably connected to the fixing column. The bottom end of the support rod is rotatably connected to a connecting plate. A plurality of reinforcing rods are provided at one end of the connecting plate. A plurality of sliding grooves are respectively formed on both sides of the fixing column. The reinforcing rods are slidably connected to the sliding grooves.

[0009] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0010] By the combined use of the protection plate, the movable groove, the first protection rod, the second protection rod, the rotating column, the movable shaft and the threaded rod, the distance between the first support column and the second support column can be adjusted to achieve the purpose of adjusting the width of the guardrail. By unscrewing the movable shaft from the threaded rod, each component can be disassembled for easy transportation, and the installation is convenient. By the mating connection between the clamping plate and the clamping groove, and then inserting a pin into the positioning hole on the clamping plate and the through hole on the second support column, the clamping plate and the second support column are limited and fixed, so as to realize the rapid connection of multiple guardrails;

[0011] By providing an anti-tipping device, through the combined use of the ground cone and the barbed plate, the stability after the installation of the first support column and the second support column can be increased. At the same time, by pressing the moving plate, the fixing column is inserted into the soil, and then the moving plate is released. Due to the elastic potential energy of the spring, the slider moves in the opposite direction through the sliding rod. The slider applies a thrust in the opposite direction to the connecting plate, and the connecting plate drives the reinforcing rod to slide out of the sliding groove and then insert into the soil for further reinforcement, further improving the stability after the installation of the first support column and the second support column, making the fixation more firm and not prone to tipping.

A plurality of positioning holes 5 are formed on the surface of the clamping plate 4. A clamping groove 6 is formed on the other side of the second support column 2. A plurality of through holes 7 are formed on the surface of the second support column 2. The positions of the positioning holes 5 and the through holes 7 are the same. The clamping plate 4 and the second support column 2 are limited and fixed by inserting a pin 8 into the positioning hole 5 on the clamping plate 4 and the through hole 7 on the second support column 2.

[0021] Embodiment 2:

[0022] As shown in the accompanying drawings of the specification Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, a prefabricated guardrail for building construction. First, the operator adjusts the first support column 1 and the second support column 2 to an appropriate distance, and then inserts the ground cone 3.2 into the soil. Through the cooperation of the ground cone 3.2 and the barbed plate 3.3, the stability of the first support column 1 and the second support column 2 after installation can be increased. At the same time, by pressing the moving plate 3.8, the fixed column 3.5 is inserted into the soil, and then the moving plate 3.8 is released. Due to the elastic potential energy of the spring 3.9, the slider 3.7 moves in the opposite direction through the slide bar 3.6. The slider 3.7 exerts a thrust in the opposite direction on the connecting plate 3.92, and the connecting plate 3.92 drives the reinforcing rod 3.92 to slide out of the sliding groove 3.94 and then insert into the soil for further reinforcement, further improving the stability of the first support column 1 and the second support column 2 after installation, making their fixation more firm and not prone to tipping. During installation, the threaded rod 9.7 is adjusted to an appropriate position in the movable groove 9.2, and then the movable shaft 9.6 is screwed on to limit and fix it. Then, the first guardrail 9.3 and the second guardrail 9.4 are rotatably connected to the movable shaft 9.6. In this way, multiple groups of guard plates 9.1 are combined repeatedly to complete the assembly of the guardrail. When it is necessary to adjust the width of the guardrail, the movable shaft 9.6 is unscrewed, and by adjusting the position of the threaded rod 9.7 in the movable groove 9.2, the distance between the first support column 1 and the second support column 2 can be adjusted to achieve the purpose of adjusting the width of the guardrail. By unscrewing the movable shaft 9.6 from the threaded rod 9.7, it can be disassembled into various components for easy transportation. When it is necessary to connect multiple guardrails, through the cooperation between the clamping plate 4 and the clamping groove 6, and then the pin 8 is inserted into the positioning hole 5 on the clamping plate 4 and the through hole 7 on the second support column 2, so as to limit and fix the clamping plate 4 and the second support column 2, thus realizing the rapid connection of multiple guardrails.
