Abstract
The utility model relates to a telescopic steel box girder guardrail pole setting, including a pole setting inserted bar and an anchor clamps, anchor clamps include the punch holder and the lower plate of rectangle, and punch holder and lower plate level set up and have a determining deviation, punch holder and lower plate one side welded connection pole, and the punch holder top surface is close to the sleeve of connecting rod one side welding vertical setting, is close to the punch holder opposite side and establishes a fastening bolt who runs through the punch holder, and the pole setting inserted bar lower extreme inserts in the sleeve on the punch holder. The utility model discloses an anchor clamps pass through fastening bolt to be fixed in steel case roof beam both sides, and the pole setting inserted bar is pegged graft with anchor clamps, and convenient and fast is dismantled in the installation, and the installation is on-the-spot does not have welding process, can avoid causing the welding to hinder to the steel case roof beam.
Description
Technical Field
The utility model belongs to the technical field of steel construction bridge construction, a structure of installing at steel box girder both sides guardrail, concretely relates to telescopic steel box girder guardrail pole setting is related to.
Background
After the steel box girder of steel structure bridge hoists and accomplishes, when carrying out the bridge floor construction, for guaranteeing constructor safety, need at the interim guardrail of steel box girder both sides installation. Traditional guardrail generally adopts little steel pipe or angle steel as guardrail pole setting lug weld at the steel box girder edge, welds twice reinforcing bar between adjacent pole setting and regards as the guardrail horizontal pole. The method needs on-site welding, cannot be constructed under the influence of rain and snow weather, and needs flame gas cutting for cutting when the guardrail is dismantled, so that not only is material waste caused, but also the base material of the steel box girder can be damaged, and the later repair workload is increased.
Disclosure of Invention
The utility model aims at providing an assembled steel case roof beam guardrail pole setting to the problem that current welding formula guardrail exists, avoids causing the damage to the steel case roof beam to it is extravagant to reduce the material.
The technical scheme of the utility model as follows:
the utility model provides a telescopic steel box girder guardrail pole setting which characterized in that: the clamp comprises a vertical rod inserted rod and a clamp, the clamp comprises a rectangular upper clamp plate and a rectangular lower clamp plate, the upper clamp plate and the lower clamp plate are horizontally arranged and have a certain distance, one side of the upper clamp plate and one side of the lower clamp plate are welded with a vertically arranged connecting rod, one side of the top surface of the upper clamp plate, which is close to the connecting rod, is welded with a vertically arranged sleeve, the other side, which is close to the upper clamp plate, is screwed with a fastening bolt, and the fastening bolt vertically penetrates through the upper clamp plate; the lower end of the vertical rod inserted rod is inserted into the sleeve on the upper clamping plate.
The utility model adopts an assembly type mounting structure, the clamp is fixed on both sides of the steel box girder through the fastening bolt, the vertical rod inserted bar is inserted with the clamp, the mounting and dismounting are convenient and fast, no welding procedure is carried out on the mounting site, and the damage to the base metal of the steel box girder can be avoided; the guardrail vertical rod can be repeatedly used after being detached, and the material waste can be avoided.

Detailed Description
As shown in fig. 1 and 2, the utility model comprises a vertical rod inserted bar 1 and a clamp, wherein the clamp comprises a rectangular upper clamping plate 2 and a rectangular lower clamping plate 3, the upper clamping plate 2 and the lower clamping plate 3 are horizontally arranged and have a certain distance, and the distance is larger than the thickness of the outer side of the flange plate of the steel box girder; one side of the upper clamping plate 2 and one side of the lower clamping plate 3 are welded with a vertically arranged connecting rod 4, one side of the top surface of the upper clamping plate 2, which is close to the connecting rod 4, is welded with a vertically arranged sleeve 5, the other side, which is close to the upper clamping plate, is provided with a fastening bolt 6, and the fastening bolt 6 vertically penetrates through the upper clamping plate; the lower end of the vertical rod inserted rod 1 is inserted into the sleeve 5 on the upper clamping plate.
In specific implementation, the cross section of the vertical rod inserting rod 1 is preferably matched with the inner cross section of the sleeve 5, so that the vertical rod inserting rod is stably inserted into the sleeve.
The upper end of the fastening bolt 6 is positioned above the clamp top plate and is provided with a rotating handle 7, so that the fastening bolt can be conveniently rotated; the lower end of the fastening bolt is positioned between the upper clamp plate and the lower clamp plate of the clamp, and the lower end of the fastening bolt 6 can be welded with a horizontally arranged backing plate 8 for tightly jacking the top plate of the steel box girder during specific implementation.
As shown in FIG. 3, the utility model discloses during the use, with the anchor clamps card in the flange plate outside of steel box girder 9, anchor clamps punch holder 2 is located steel box girder flange plate top, and steel box girder flange plate bottom surface is hugged closely to lower plate 3, screws up fastening bolt 6 downwards, and fastening bolt 6 lower extreme top tightness steel box girder 9's flange plate top surface makes anchor clamps fix on steel box girder flange plate. And (3) inserting the upright rod inserting rod 1 into the sleeve 5 on the clamp to complete the installation of the guardrail upright rod.
Claims (3)
1. The utility model provides a telescopic steel box girder guardrail pole setting which characterized in that: the clamp comprises a vertical rod inserted rod and a clamp, the clamp comprises a rectangular upper clamp plate and a rectangular lower clamp plate, the upper clamp plate and the lower clamp plate are horizontally arranged and have a certain distance, one side of the upper clamp plate and one side of the lower clamp plate are welded with a vertically arranged connecting rod, one side of the top surface of the upper clamp plate, which is close to the connecting rod, is welded with a vertically arranged sleeve, the other side, which is close to the upper clamp plate, is screwed with a fastening bolt, and the fastening bolt vertically penetrates through the upper clamp plate; the lower end of the vertical rod inserted rod is inserted into the sleeve on the upper clamping plate.
