Description

Technical Field

[0001] The present application relates to the technical field of road construction, and in particular to a guardrail post installation tool. Background Art

[0002] Cable guardrails are often installed in the middle isolation zone of the landscape avenue and on both sides of the avenue. The cable guardrail is transparent and beautiful, can be coordinated with the landscape along the road, and is more ornamental. The cable guardrail includes steel columns and steel wire ropes connecting the steel columns. When installing the cable guardrail, it is necessary to first connect multiple steel columns to the ground, and then install the steel wire rope, which connects multiple steel columns. When installing the steel columns, it is necessary to pour a concrete foundation under the steel columns to fix the steel columns to the ground. Two cable guardrails need to be installed at the central isolation zone of the landscape avenue. In order to maintain the beauty, the two guardrail columns need to be set side by side with the same spacing. The existing construction method usually installs one row of steel columns before installing another row of steel columns, or divides the construction workers into two groups to install at the same time. This has low work efficiency and consumes more manpower, and it is difficult to ensure the smoothness of the guardrail line and the coordination of the appearance. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to solve the problems of low installation efficiency and poor positioning accuracy of cable guardrails, the present application provides a guardrail post installation tool. In order to make the purpose, technical solution and advantages of the present application clearer, the present application is further described in detail below with reference to the accompanying drawings.

[0023] Figure 1 A schematic diagram of the structure of a guardrail post installation tool provided in one embodiment of the present application. Figure 1 As shown, an embodiment of the present application provides a guardrail post installation tool, comprising two fixing grooves 1 adapted to the guardrail post 0, each fixing groove 1 being used to accommodate a guardrail post 0, so that the guardrail post 0 is fixed to the guardrail post installation tool. The extension directions of the two fixing grooves 1 are parallel to each other, and the two fixing grooves 1 are spaced apart by a preset distance. When installing the guardrail post 0, the extension directions of the two fixing grooves 1 are perpendicular to the ground A.

[0024] Figure 2 A layout diagram of guardrail posts in a central isolation zone provided for an embodiment of the present application, such as Figure 2As shown, during construction, firstly, measurement and laying out are carried out, and the surveying personnel mark the positioning lines of the installation position of the guardrail column 0 on the upper surface of the curbstones 101 on both sides of the central isolation zone 100. The total width of the central isolation zone 100 is 1700mm, and the distance between the two positioning lines is 4000mm along the extension direction of the central isolation zone 100, which is hereinafter referred to as the first direction M. The direction perpendicular to the extension direction of the central isolation zone 100 is hereinafter referred to as the second direction N. Then, a drilling rig is used to drill holes between the curbstones 101 on both sides of the isolation zone, and the two holes are symmetrically arranged along the center line 102 of the central isolation zone. The drilling depth is 1200mm from the top of the curbstone 101 to the bottom of the hole. After the drilling is completed, the guardrail column installation tool is set on the curbstone 101 according to the position of the positioning line. Make the extension direction of the fixing groove 1 perpendicular to the ground A, and each fixing groove 1 corresponds to a hole. Each guardrail post 0 is placed in a fixing groove 1, and the guardrail post installation tool can position and install two guardrail posts 0 at the same time, thereby improving the installation efficiency and precision control level, reducing manpower, and saving construction costs.

[0025] Figure 3 A schematic diagram of the structure of a guardrail post installation tool provided in another embodiment of the present application is shown in FIG. Figure 3 As shown, in one embodiment, the guardrail post installation tool comprises a support frame 00 and two brackets 01, the two brackets 01 are installed on the side of the support frame 00, and each bracket 01 has a fixing groove 1. The bracket 01 is located on the side of the support frame 00, which is convenient for hanging the guardrail post 0 on the bracket 01, making the operation more labor-saving.

[0026] Figure 4 A side view of a guardrail post installation tool provided in one embodiment of the present application, Figure 5 A top view of the guardrail post installation tool and the guardrail post assembled in accordance with an embodiment of the present application. Figure 3 to Figure 5In a specific embodiment, the two brackets 01 include a first bracket 011 and a second bracket 012, and the two fixing grooves 1 include a first fixing groove 11 and a second fixing groove 12. The first bracket 011 includes a first angle steel 111 and a second angle steel 112, and the first angle steel 111 and the second angle steel 112 are arranged opposite to each other to form a first fixing groove 11. Angle steel is a commonly used structural member in the prior art, which is composed of two vertically arranged strips, and one long side of the two strips is connected together to form a structural member with a 90° angle. The first angle steel 111 and the second angle steel 112 are arranged opposite to each other, and a certain gap can be left between them to meet the lateral width of the guardrail column 0. The first angle steel 111 and the second angle steel 112 form a first fixing groove 11 with a rectangular cross section. The bottom width of the fixing groove 1 is roughly the same as the width of the guardrail column 0, and is slightly larger than the width of the column 0, so that the column 0 can be effectively fixed and avoid being unable to be placed in the fixing groove. During installation, the guardrail post 0 is embedded in the first fixing groove 11 to achieve positioning, and the guardrail post 0 can be called the first post 001. Similarly, the second bracket 012 includes a third angle steel 121 and a fourth angle steel 122, which are arranged opposite to each other to form a second fixing groove 12. The second fixing groove 12 achieves the positioning of the second post 002.

[0027] The above-mentioned column is connected to the bracket 01 through a connecting piece. In one embodiment, the connecting piece can be a fixing bolt 10. Specifically, the above-mentioned guardrail column 0 includes two opposite first side surfaces and a second side surface. The two opposite side surfaces are respectively provided with a plurality of through holes at equal intervals along a direction perpendicular to the ground. These through holes are used to install the connecting piece for fixing the cable. The through holes on the first side surface correspond to the through holes on the second side surface in a one-to-one relationship. When the guardrail column 0 is installed on the guardrail column installation tool, the above-mentioned first side surface and the second side surface are arranged along the second direction N. Then insert the fixing bolt 10 into any two corresponding through holes, such as Figure 1 , and then the fixing bolt 10 is clamped on the top of the first bracket 011, or clamped on the top of the second bracket 012, so that the guardrail post 0 is suspended on the bracket 01. Under the action of gravity, the guardrail post 0 and the bracket 01 are relatively stationary, and the fixing groove 1 is achieved.

[0028] It is worth noting that using the above-mentioned fixing bolt 10 as a connecting piece to hang the column 0 on the bracket 01 is a way to fix the column 0. In other embodiments, other forms of connecting pieces can also be used to fix the column 0 to the bracket 01. For example, the connecting piece can be a magnet. The column 0 is a steel column with magnetic conductivity. A magnet is set in the fixing groove 1 of the bracket 01, or a magnet is set on the steel column. The column 0 is fixed on the bracket 01 through the adsorption force of the magnet.

[0029] In a specific embodiment, the size of the guardrail column 0 is 50mm×100mm×2200mm, and the net distance between the two columns is 664mm along the second direction N. The guardrail column 0 is a standard part. According to the construction requirements, the fixing bolt 10 is inserted into the third through hole of the guardrail column 0 from the top to the bottom, and then the fixing bolt 10 is hung on the top of the bracket 01. At this time, the installation height of the guardrail column 0 is consistent with the design drawing, that is, the top of the guardrail column 0 is 1000mm higher than the top surface of the curb 101.

[0030] The structure of the support frame 00 is described below.

[0031] In one embodiment, the support frame 00 includes a top beam 2, a first bottom beam 3, a second bottom beam 4, a diagonal bracing beam 5 and a transverse bracing beam 6. The top beam 2, the first bottom beam 3 and the second bottom beam 4 are arranged parallel to each other, and the orthographic projections of the top beam 2 and the first bottom beam 3 overlap in a direction perpendicular to the ground, and two brackets 01 are respectively connected to the top beam 2 and the first bottom beam 3. The diagonal bracing beam 5 is connected between the top beam 2 and the second bottom beam 4, or the diagonal bracing beam 5 is connected between the bracket 01 and the second bottom beam 4. The transverse bracing beam 6 is connected between the first bottom beam 3 and the second bottom beam 4. The diagonal bracing beam 5 and the transverse bracing beam 6 have an acute angle. Along the second direction N, the support frame 00 and the bracket 01 form a triangular frame, which has a stable structure and improves the reliability of the guardrail post installation tool.

[0032] Of course, the support frame 00 can also be a frame of other shapes, such as a rectangular frame, a trapezoidal frame, etc. The support frame 00 of other forms can achieve the function of fixing the bracket 01, and this application does not make specific restrictions.

[0033] In one embodiment, the length of the first bottom beam 3 and the second bottom beam 4 along the second direction N is greater than the spacing between the curbstones 101 on both sides of the central isolation zone 100, so that the guardrail column installation tool can be erected above the curbstones 101 on both sides.

[0034] In one embodiment, the length of the first bottom beam 3 may be greater than the length of the top beam 2 , and the length of the second bottom beam 4 may be greater than the length of the top beam 2 .

[0035] After the guardrail post installation tool is set up, the construction personnel use a level ruler to perform a leveling operation. Specifically, the level ruler is placed on the top beam 2 to adjust the flatness of the guardrail post installation tool, and then the level ruler is placed in the bracket 01 to adjust the verticality of the guardrail post installation tool until the guardrail post installation tool is leveled.

[0036] In one embodiment, the support frame 00 further includes a fixed beam support seat 7, which is fixedly connected to the first bottom beam 3, and the fixed beam support seat 7 is located between the first bracket 011 and the second bracket 012 along the second direction N.

[0037] In one embodiment, the guardrail post installation tool further includes a fixed beam 8, which is detachably connected to the fixed beam support seat 7, and is located at the notch of the fixing slot 1. The fixed beam 8 extends in the second direction N, and the fixed beam 8 is perpendicular to the extension direction of the fixing slot 1. The fixed beam 8 is used to limit the movement of the guardrail post 0 along the first direction M. After the first column 001 and the second column 002 are respectively installed in the first fixing slot 11 and the second fixing slot 12, the fixed beam 8 is installed on the fixed beam support seat 7, so that the fixed beam 8 is located on the side of the first column 001 and the second column 002, so that the movement of the first column 001 and the second column 002 along the first direction M is restricted, and the first column 001 and the second column 002 are reduced from falling off the guardrail post installation tool.

[0038] In a specific embodiment, the fixed beam support seat 7 includes a base 71, a stopper 72 and a fifth angle steel 73. The base 71 is fixedly mounted on the first bottom beam 3. The stopper 72 and the fifth angle steel 73 are mounted on the side of the base 71 away from the ground. The fifth angle steel 73 is parallel to the first bottom beam 3. The fifth angle steel 73 includes a first side plate 730, and the first side plate 730 is perpendicular to the base 71. An accommodating space is formed between the first side plate 730 and the stopper 72, and the fixed beam 8 is detachably mounted in the accommodating space.

[0039] After fixing the two guardrail posts 0, the construction workers poured the foundation concrete in the hole and vibrated it to make it dense. After the foundation concrete solidified, the fixed beam 8 was removed, and then the guardrail post installation tool was removed. The installation of the guardrail post 0 was completed.
