Description
Technical Field
The utility model relates to an used steel bushing case installation technical field of aquatic bridge construction, concretely relates to setting supports pedestrian's passageway at steel pipe top in steel bushing case.
Background
When the steel sleeve box is used for underwater bridge construction, a dry and waterless environment is provided for a construction area. The steel casing side plates bear huge water pressure in water, and because the steel pipe piles have good axial compressive strength, a plurality of horizontally arranged steel pipe piles are supported between the opposite side plates in a criss-cross mode in the steel casing to serve as an inner supporting structure for resisting external water pressure.
In the process of installing the steel jacket box, constructors need to operate inside the steel jacket box. Because the construction point positions are dispersed in a plurality of positions in the steel sleeve box, the steel sleeve box is large in size and generally has a length and a width of more than ten meters, and construction operators usually use the inner support steel pipe as a walking channel from one construction point to another construction point. Because the support steel pipe below is unsettled and higher from the steel bushing bottom surface, in order to guarantee personnel's safety of walking, common way is that the welding has the reinforcing bar of certain height as the guardrail in support steel pipe both sides, though simple structure, but the welding can cause certain damage to the steel pipe, influences the reuse, and the steel pipe surface is smooth arc simultaneously, and the pedestrian walks very insecure above that.
Disclosure of Invention
The utility model aims to provide a setting supports the pedestrian passageway at steel pipe top in the steel bushing incasement to the demand of steel bushing incasement construction, is guaranteeing under the prerequisite of constructor safety, avoids the damage of internally supporting the steel pipe, and it is extravagant to reduce the material.
The technical scheme of the utility model as follows:
the utility model provides a setting is at steel bushing incasement support pedestrian passageway on steel pipe which characterized in that: the steel supporting box is characterized in that hoops are arranged on the steel supporting tubes in the steel sleeve box at intervals, each hoop comprises two semicircular hoop plates, two sides of each hoop plate are respectively provided with an outward extending hoop connecting plate, the two hoop plates are buckled on the supporting steel tubes one above the other and are connected through the hoop connecting plates on the two sides of the hoop plates by hoop bolts to be tightly held on the supporting steel tubes; a vertical guardrail fixing rod is arranged on connecting plates on two sides of the upper hoop plate, the lower end of the guardrail fixing rod is welded with the hoop connecting plate, one end of a cross rod is welded at the upper end of the guardrail fixing rod, and the other end of the cross rod is welded with the outer wall of the upper hoop plate; a guardrail vertical rod is respectively supported on the connecting plates at the two sides of each upper hoop plate, and the guardrail vertical rods are connected with the guardrail fixing rods through bolts; arranging a row of guardrail cross bars at regular intervals between the guardrail upright bars on each side of the support steel pipe, wherein the guardrail cross bars are made of angle steel, one edge of the angle steel is connected with the guardrail upright bars through bolts, the other edge of the angle steel is positioned at the inner sides of the guardrail upright bars, and the top surface height of the angle steel edge, facing the inner sides of the guardrail upright bars, of the lowest row of guardrail cross bars on the guardrail upright bars is flush with the top surface height of the support steel pipe; a pedestrian passageway panel is erected on the supporting steel pipe, the middle of the pedestrian passageway panel is supported on the top surface of the supporting steel pipe, and two sides of the pedestrian passageway panel are supported on the edge of the angle steel of the guardrail cross rod which is highly flush with the top surface of the supporting steel pipe.
The utility model has the advantages of all components are bolted connection, and the on-the-spot welding operation that does not have during installation, it is convenient to install, to supporting the steel pipe not damaged, has improved the integrality and the reuse ratio of material, and the panel can select steel sheet or plank according to the current material of job site, and the panel both sides are directly supported on the inboard bottom guardrail horizontal pole of pole setting, and the panel middle part supports in interior support steel pipe top, the walking of being convenient for, and stability is good, can fully ensure the current safety of constructor.
