[0002] During the construction process, the entire production process from construction preparation, ground breaking to project completion acceptance requires isolation and protection of the construction site.
[0003] When the existing guardrails are in use, the guardrail brackets are generally directly fixed to the ground by bolts or welding to ensure the stability of the guardrails. However, during the construction process, there are occasional situations where it is necessary to move the guardrails. For example, if a vehicle carrying equipment exceeds the height of the construction site gate, it is necessary to move the fence to open a temporary passage. However, the traditional guardrail brackets are directly fixed to the ground, and special disassembly tools are required, which is very inconvenient to disassemble. At the same time, it is also very inconvenient for subsequent reinstallation, and the time cost is relatively high when moving the guardrails.
[0004] Based on this, the utility model designs a detachable bracket for a construction guardrail to solve the above problems. Content of the Utility Model

[0006] As a further solution of the utility model, the first part is a plugging groove provided on the inner side wall of the limiting groove, and the second part is a plugging rod elastically and slidably installed at the bottom end of the column; the plugging rod has a plugging end for inserting into the plugging groove and a pressing end exposed outside the limiting groove in the connected state, and two round holes are provided on the surface of the column, and the two round holes are respectively used for allowing the plugging end and the pressing end to pass through, so that the plugging end and the pressing end of the plugging rod installed in the inner cavity of the column protrude from the outer surface of the column.
[0007] As a further solution of the present utility model, a guiding inclined surface is provided at one end of the insertion end protruding from the outer surface of the column. The distance from the lower end of the guiding inclined surface to the outer surface of the column is less than the distance from the upper end of the guiding inclined surface to the outer surface of the column. An expanding groove is provided at the top end of the limiting groove, and the minimum distance from the center of the expanding groove to the expanding groove is greater than the minimum distance from the center of the column to the bottom end of the guiding inclined surface.
[0008] As a further solution of the present utility model, the distance from the insertion slot to the bottom surface of the limiting groove is the same as the distance from the insertion rod to the bottom surface of the column.

[0027] The following will provide a detailed description of the embodiments of the present utility model with reference to the drawings. However, the present utility model can be implemented in many different ways defined and covered by the following.
[0028] Please refer to Figures 1-6, the present utility model provides a detachable bracket for construction guardrails, which includes a base 1, a column 2 for installing guardrails, and a connecting mechanism for detachably installing the column 2 on the base 1. By separating the bracket into two parts, namely the base 1 and the column 2, and realizing the detachable installation between the column 2 and the base 1 through the connecting mechanism. That is to say, when it is necessary to remove the column 2 in case of special circumstances, the column 2 and the base 1 can be quickly separated. Compared with the column 2, the height of the base 1 is much lower than that of the column 2, and normal vehicles can pass above the base 1 without affecting the trafficability of the road surface at the installation position of the base 1;
[0029] The base 1 is fixed to the ground, and a limiting groove 11 for installing the column 2 is provided on the top surface of the base 1. The shape and size of the bottom end of the column 2 match the opening shape and size of the limiting groove 11, so that the bottom end of the column 2 can be inserted into the limiting groove 11 and fit with the limiting groove 11 with a clearance. Through the clearance fit between the bottom end of the column 2 and the limiting groove 11, the side of the limiting groove 11 laterally supports the column 2 to prevent the column 2 from tilting during use and improve the stability of the column 2;
[0030] The connecting mechanism includes a first part provided in the limiting groove 11 and a second part provided at the bottom end of the column 2. The first part and the second part include a connected state for preventing the bottom end of the column 2 from exiting the limiting groove 11 and a separated state for allowing the bottom end of the column 2 to freely enter and exit the limiting groove 11. In the first state, the column 2 and the base 1 are firmly connected together to install a guardrail or a fence on the side of the column 2, ensuring the stability of the guardrail installation and preventing the guardrail from shifting and overturning under external forces. When it is necessary to disassemble the column 2 from the base 1, the first state of the first part and the second part can be changed to the second state. At this time, the column 2 can be easily separated from the limiting groove 11 to cope with emergencies, quickly realizing the disassembly of the column. It is also simpler to reinstall after disassembly.
[0031] Figure 2 The first example of the connecting mechanism is shown. In this example, the first part is a socket groove 31 opened on the inner side wall of the limiting groove 11, and the second part is a socket rod 32 elastically and slidably installed at the bottom end of the column 2. The column 2 is restricted in the limiting groove 11 by inserting the end of the socket rod 32 into the socket groove 31, realizing the connection between the column 2 and the base 1;
[0032] Specifically, the insertion rod 32 has an insertion end 33 for inserting into the insertion slot 31 and a pressing end 34 that is exposed in the limiting slot 11 in the connected state. Two circular holes are formed on the surface of the column 2, and the two circular holes are respectively used for the insertion end 33 and the pressing end 34 to pass through, so that the insertion end 33 and the pressing end 34 of the insertion rod 32 installed in the inner cavity of the column 2 protrude from the outer surface of the column 2. In the first state, the insertion end 33 of the insertion rod 32 is inserted into the insertion hole formed in the limiting slot 11. At this time, the bottom end of the column 2 cannot leave the limiting slot 11, realizing the connection between the column 2 and the base 1. When it is necessary to separate the column 2 and the base 1, only need to press the pressing end 34 of the insertion rod 32 exposed from the surface of the column 2, so that the pressing end 34 of the insertion rod 32 moves towards the inner cavity of the column 2, thereby driving the insertion end 33 of the insertion rod 32 to move synchronously towards the inner cavity of the column 2, so that the insertion end 33 is withdrawn from the insertion slot 31. Thus, the second state of the insertion rod 32 and the insertion slot 31 is realized, and the bottom end of the column 2 can freely enter and exit the limiting slot 11.
[0033] Figure 2 An installation example of the insertion rod 32 is shown. In this example, a spring is fixedly installed in the inner cavity of the column 2 through a mounting plate. One end of the spring away from the mounting plate abuts or is fixedly connected to the surface of the insertion rod 32 facing the center of the column 2, so as to store elastic potential energy when the insertion rod 32 moves towards the center of the column 2, and release the elastic potential energy to help the insertion rod 32 move away from the center of the column 2 after the surface pressure of the pressing end 34 of the insertion rod 32 disappears.
[0034] In this embodiment, since the insertion end 33 of the insertion rod 32 protrudes from the outer surface of the column 2, during the process of inserting the column 2 downward into the limiting slot 11, the insertion end 33 of the insertion rod 32 will collide with the top surface of the base 1. Therefore, a guiding inclined surface 35 is formed at one end of the insertion end 33 protruding from the outer surface of the column 2. The distance from the lower end of the guiding inclined surface 35 to the outer surface of the column 2 is less than the distance from the upper end of the guiding inclined surface 35 to the outer surface of the column 2. An enlarged opening groove 12 is formed at the top end of the limiting slot 11. The minimum distance from the center of the enlarged opening groove 12 to the enlarged opening groove 12 is greater than the minimum distance from the center of the column 2 to the bottom end of the guiding inclined surface 35. That is to say, when the bottom end of the column 2 is inserted into the limiting slot 11, the lower end of the guiding inclined surface 35 of the insertion end 33 will first abut against the side surface of the enlarged opening groove 12. During the process of the column 2 descending, through the cooperation of the guiding inclined surface 35 and the enlarged opening groove 12, the insertion rod 32 is subjected to a thrust force towards the inner cavity of the column 2, so that the insertion rod 32 can automatically retract and avoid the top surface of the base 1 during the process of inserting the bottom end of the column 2 into the limiting slot 11, which is more convenient to use.
[0035] In this example, the opening shape of the limiting slot 11 can be any shape, and the present application does not limit this.
[0036] Specifically, the distance from the insertion slot 31 to the bottom surface of the limit slot 11 is the same as the distance from the insertion rod 32 to the bottom surface of the column 2. Thus, when the insertion rod 32 is inserted into the insertion slot 31, the bottom end of the column 2 can contact the bottom end surface of the limit slot 11, and the bottom end of the limit slot 11 supports the column 2 to ensure the stability of the column 2.
[0037] Figures 3-5 The second example of the connection mechanism is shown. In this example, the first part of the connection mechanism is a connection head 41 with an external thread on its surface fixedly installed in the limit slot 11, the second part is an operating rod 42 passing through the column 2 and a connection sleeve 43 fixed to the bottom end of the operating rod 42 for threaded engagement with the connection head 41. The operating rod 42 is rotationally fitted with the column 2 with its own axis as the rotation axis. By rotating the operating rod 42, the connection sleeve 43 at the bottom end of the operating rod 42 is threadedly engaged with the connection head 41 on the base 1 to achieve the connection state of the connection sleeve 43 and the connection head 41. The column 2 is pressed against the base 1 through the operating rod 42 to fixedly connect the column 2 and the base 1. When it is necessary to separate the column 2 from the base 1, the operating rod 42 is also rotated to disengage the connection sleeve 43 from the connection head 41 to achieve the separation state of the connection sleeve 43 and the connection head 41. Thus, the column 2 and the base 1 can be easily separated, and when the column 2 needs to be disassembled, it can be more rapid and convenient. At the same time, it is also convenient for the subsequent installation of the column 2 and the base 1 to cope with unexpected situations during the actual construction process.
[0038] Specifically, as Figure 4 shown, the top end of the operating rod 42 protrudes from the top surface of the column 2, and a knob 44 is provided at the top end of the operating rod 42. The operating rod 42 is rotated through the knob 44 at the top of the operating rod 42, which is convenient for applying force. At the same time, the top end of the operating rod 42 protrudes from the top surface of the column 2, providing a larger force application space when rotating the operating rod 42.
[0039] The knob 44 is a rod body with a semi-circular configuration, and the knob 44 is rotatably arranged along the horizontal line at the top end of the operating rod 42. A groove 21 for accommodating the knob 44 is provided at the top end of the operating rod 42. The knob 44 can rotate around the horizontal line and switch between the upright state and the horizontal state. When the knob 44 is in the upright state, the knob 44 can be held to apply force to rotate the operating rod 42, and when the knob 44 is in the horizontal state, the knob 44 will be hidden in the groove 21 to prevent the operating rod 42 from rotating due to misoperation and increase the overall aesthetics.
[0040] The opening shape of the limit slot 11 is any shape other than a circle. When the opening shape of the limit slot 11 is a circle, then the bottom end of the column 2 is also correspondingly circular. At this time, the column 2 can rotate freely in the limit slot 11, and when the connection head 41 and the connection sleeve 43 are in the connected state, they cannot restrict the rotation of the column 2. Therefore, the opening shape of the limit slot 11 cannot be a circle.
[0041] As Figure 3 shown, in this example, the opening shape of the limit groove 11 is rectangular.
[0042] In this example, the side wall of the column 2 is provided with an installation structure for installing a guardrail. The installation structure varies according to the type of guardrail to be installed and needs to be designed according to the actual usage scenario, such as Figure 1 the mounting plate installed on the side of the middle column, or Figure 6 the bottom bracket shown.
[0043] In this example, the side of the base 1 is fixedly provided with an ear plate 13. The surface of the ear plate 13 is provided with a fixing hole that penetrates the ear plate 13 vertically. By passing a screw or bolt through the fixing hole opened in the ear plate 13 and inserting it into the ground, the fixed connection between the base 1 and the ground is realized.
[0044] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
