The utility model has no welding construction in the installation process, and can not damage the arch rib; the opposite pull rod can be used as an anti-skid device when constructors walk on the top of the arch rib, and construction safety is improved.
Description
Technical Field
The utility model relates to a steel case arched bridge construction technical field, concretely relates to set up at assembled pedestrian passageway guardrail of steel case vault costal part.
Background
In the construction process of the steel box arch bridge, when the welding and coating operation of the arch rib is carried out, the top surface of the arch rib is usually used as a pedestrian passage for the construction personnel to pass. In order to ensure the construction safety, guardrails are required to be arranged on two sides of the arch rib. The existing guardrail mounting mode is that the lower ends of guardrail vertical rods are directly welded on the two sides of the top of an arch rib, and the vertical rods are connected through a cross rod to form a guardrail. The existing guardrail installation mode needs welding construction, has large damage to the arch rib structure, needs cutting during dismantling, and also needs repairing treatment on the surface of the arch rib after dismantling to influence the construction progress; and constructors walk on the arch rib and are influenced by the radian of the arch rib, the feet of the constructors slip easily, and the safety risk of the constructors is increased.
Disclosure of Invention
The utility model aims at the above-mentioned problem, a assembled pedestrian passageway guardrail for steel box arch rib top is provided, and the guardrail installation need not weld, avoids causing the damage to the arch rib to improve the security of guardrail.
The technical scheme of the utility model as follows:
the utility model provides an assembled pedestrian passageway guardrail for steel case arch rib top, includes the many guardrail pole settings that set up along the arch rib both sides, connects its characterized in that through the horizontal pole between the guardrail pole setting of every side: the two sides of the arch rib are respectively provided with a baffle plate, the lower half part of each baffle plate is tightly attached to the side wall of the arch rib, the upper half part of each baffle plate is higher than the top surface of the arch rib, clamping plates which are vertically arranged and are vertical to the baffles are welded at certain intervals at the parts of the baffle plates higher than the top surface of the arch rib, one side edge of each clamping plate is welded with the side wall of each baffle plate, and the bottom edge of each clamping plate is supported on the; the lower end of the guardrail upright stanchion is supported on the top surface of the arch rib and is connected with the baffle plate through a bolt; a pair of pull rods is arranged between the two baffle plates at intervals, the pair of pull rods is tightly attached to the top surfaces of the arch ribs, and two ends of each pull rod respectively penetrate through the two side plates and are in threaded connection with a fixing nut.
The utility model adopts the assembly type mounting structure, no welding construction is adopted in the mounting process, and the arch rib is not damaged; the counter-pull rod can be used as an anti-skid device when constructors walk on the top of the arch rib, so that the construction safety is improved; the guardrail can be repeatedly used after being dismantled, and the construction cost can be reduced.

Detailed Description
As shown in fig. 1, 2 and 3, the utility model comprises a plurality of guardrail vertical rods 2 arranged along two sides of an arch rib 1, and the guardrail vertical rods 2 at each side are connected by a cross rod 3; the two sides of the arch rib 1 are respectively provided with a baffle 4, the lower half part of the baffle 4 is tightly attached to the side wall of the arch rib 1, the upper half part of the baffle is higher than the top surface of the arch rib, a clamping plate 5 which is vertically arranged and is vertical to the baffle is welded at certain intervals at the part of the baffle 4 higher than the top surface of the arch rib, one side edge of the clamping plate 5 is welded with the side wall of the baffle 4, and the bottom edge of the clamping plate 5 is supported on the top surface of the arch rib 1; the lower end of the guardrail upright stanchion 2 is supported on the top surface of the arch rib 1 and is connected with the baffle 4 through a bolt 6; a pair of pull rods 7 is arranged between the two baffle plates 4 at intervals, the pull rods 7 are tightly attached to the top surfaces of the arch ribs 1, and two ends of each pull rod 7 penetrate through the two side plates 4 respectively and are in threaded connection with fixing nuts 8.
When the utility model is implemented, the upright stanchion of the guardrail can adopt angle steel, and the lower end of one edge of the angle steel is provided with a screw hole for connecting with the baffle plate through a bolt; the baffle plate is made of a strip-shaped steel plate with a certain width, and screw holes are preset according to the design interval of the guardrail upright rods; the upper half part of the baffle plate is used for being connected with the upright stanchion of the guardrail and can also have the function of a skirting board to prevent sundries at the top of the arch rib from falling off; the clamping plate mainly has a stabilizing effect on the baffle and can adopt a triangular steel plate to save materials; the distance between the opposite pull rods can be reasonably set according to the walking stride of the workers, so that the opposite pull rods not only tension the baffles on the two sides of the arch rib, but also can be used as an anti-skid device for the workers to walk on the arch crown.
