Wind-resistant support rods for road construction sealing slabs

Abstract

The invention discloses a wind-resistant support bar used for road construction road sealing boards, which comprises a transverse steel plate (1) and a longitudinal steel plate (2), and the transverse steel plate (1) and the longitudinal steel plate (2) are welded transversely and longitudinally to form a whole It is a cross-shaped steel plate structure, and also includes 4 concrete counterweights (5), the upper end of the concrete counterweight has a groove, and a lead block (12) is arranged in the groove, and there are 2 concrete counterweights The upper end faces of the two concrete counterweights are respectively installed on the lower sides of the two ends of the horizontal steel plate (1) through the steel plate fixing screws (13), and the upper end faces of the other two concrete counterweights are respectively installed under the two ends of the longitudinal steel plates through the steel plate fixing screws (13). side; the central area of ​​the cross-shaped steel plate structure is provided with a collar (4), and a support rod is inserted into the collar. The invention has the advantages of simple structure, low cost, simple and fast operation, and can quickly and conveniently erect the wind-resistant support rod used for road construction road sealing slabs.

Description

technical field [0001] The invention relates to a road sealing board structure for road construction, in particular to a wind-resistant support rod used for road construction road sealing boards. Background technique [0002] Road sealing board is a common construction protection device for road construction. Its main function is to isolate the construction area and non-construction area. The structure of the existing road sealing board mainly includes multiple columns, and isolation plates are installed between the columns. The installation method of the column is to directly open a hole on the ground, and then nail the expansion screw on the ground, and use the expansion screw to fix the end of the column, which plays a stable role. This construction method can play a very good stability. , the road sealing board is not easy to collapse, especially in coastal areas with strong wind, the above method is generally used, however, this method has high damage to the road, compl...

[0002] Road sealing board is a common construction protection device for road construction. Its main function is to isolate the construction area and non-construction area. The structure of the existing road sealing board mainly includes multiple columns, and isolation plates are installed between the columns. The installation method of the column is to directly open a hole on the ground, and then nail the expansion screw on the ground, and use the expansion screw to fix the end of the column, which plays a stable role. This construction method can play a very good stability. , the road sealing board is not easy to collapse, especially in coastal areas with strong wind, the above method is generally used, however, this method has high damage to the road, complicated construction, needs to be connected to the construction power supply, and is used for drilling, so it is necessary The power department cooperates with the construction, and at the same time, the road management department needs to approve the drilling, and the drilling must be backfilled after the construction is completed.

The entire construction period is long and the road is seriously damaged. Therefore, frame-type column construction is generally used. The frame-type column structure is to install multiple supporting steel columns at the bottom of the column, and directly place the supporting steel columns on the ground. There is a construction method of this kind. The problem of safety performance is easy to collapse, especially in areas with strong winds. Such a construction method has not been seen, and it is generally suitable for inland areas with low winds.
