Abstract
The invention relates to a connecting node structure of steel rod elements and a concrete plate, which comprises steel rod elements, a concrete plate and perforated plate connecting elements. The steel rod elements are connected by stiffening plates. The steel rod elements and the stiffening plates are connected to the lower surface of a steel bearing plate. The perforated plate connecting elements are connected to the upper surface of the steel bearing plate. The concrete plate is poured for wrapping the perforated plate connecting elements. The open hole of each perforated plate connecting element is a circular hole or an elliptical hole. A notch can be arranged on the hole opening position of each perforated plate connecting element. Two perforated plate connecting elements are arranged in parallel with opposite hole opening positions, and through reinforcing steel bars are arranged in the holes. The perforated plate connecting elements are mutually vertical to the steel bearing plate. The connecting node structure has the advantages of simple structure, clear and definite force transmission, convenient construction and the like.
Description
Technical field
The invention belongs to technical field of bridge engineering, relate to the connected node structure of steel rod elements and concrete slab.
Background technology
Traditional composite roof truss bridge combines the steel web member by the string wire bar is set with concrete slab, weldering nail connector and concrete slab longitudinally are set on the string wire bar mutually combine.Most of load action will be born by concrete slab when the composite roof truss bridge is in the positive bending moment district, the steel web ends is directly combined with concrete slab for this reason, and omission string wire bar structure, more reasonable stressed.In addition for when the bridge floor broad, the bridge construction section form that adopts single case combined box beam and peripheral hardware steel diagonal brace to combine with concrete slab, the bridge floor load action need guarantee that by the connected node transmission of bridge deck and the outer steel rod elements of face joint structure is reasonable, power transmission is reliable.
Existing steel rod elements and concrete slab connected node structure are that the steel rod elements that steel lattice chamber is being welded in the end is directly inserted concrete slab, and steel lattice chamber sidewall is provided with circular hole and runs through reinforcing bar, or weld anchor pole in the steel rod elements end, reinforcing bar plays interconnect function.But its joint construction is comparatively complicated, has increased difficulty of construction.
Summary of the invention
The object of the present invention is to provide a kind of steel rod elements and concrete slab connected node structure, reduce node processing capacity and difficulty of construction, and simple structure, power transmission are clear and definite.
For reaching above purpose, solution of the present invention is: a kind of steel rod elements and concrete slab connected node structure, comprise steel rod elements, concrete slab, perforated panel connector, connect by stiffener between the described steel rod elements, steel rod elements, stiffener are connected steel bearing plate soffit, the perforated panel connector is connected steel bearing plate upper surface, concrete slab cast parcel perforated panel connector.Connect by stiffener between the steel rod elements, steel rod elements, stiffener are connected steel bearing plate soffit, and the perforated panel connector is connected steel bearing plate upper surface, concrete slab cast parcel perforated panel connector.
Further, steel rod elements is steel pipe, shaped steel, concrete filled steel tube and welding opening section rod member.
Between steel rod elements and the stiffener, between steel rod elements and the steel bearing plate, between stiffener and the steel bearing plate, and be welding manner between perforated panel connector and the steel bearing plate and be connected.
The perforate of perforated panel connector is circular port or slotted eye.
Perforated panel connector position of opening top can be provided with breach.
Parallel placement, the corresponding two perforated panel connectors of position of opening have been adopted.
Place in the perforated panel connector hole and connect reinforcing bar.Described perforated panel connector is vertical mutually with the steel bearing plate.
Owing to adopted such scheme, the present invention to have following characteristics:
Connect the perforated panel connector on the steel bearing plate, can be used as the floor of putting more energy into of steel bearing plate.
Connect reinforcing bar in the perforated panel connector hole on the steel bearing plate, can improve the shearing resistance and the anti-pulling bearing capacity of node.
Perforated panel connector on the steel bearing plate can be provided with circular port, slotted eye, makes things convenient for the location of reinforcing bar in the hole to arrange.
Can offer breach in the perforated panel connector hole on the steel bearing plate, make things convenient for the construction that runs through of reinforcing bar in the hole.
Steel rod elements and concrete slab connected node need not to apply prestressing force, have saved cost and have improved speed of application.
Adopt the stiffener that separates that steel rod elements is linked together and both strengthened the globality of structure, also simplified the connection operation between the steel rod elements, reduce labor content.
Description of drawings
Fig. 1 is steel rod elements of the present invention and concrete slab connected node organigram.
Fig. 2 is the schematic diagram in perforated panel connector opened round hole.
Fig. 3 opens slotted eye for the perforated panel connector and establishes the schematic diagram of breach.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described.
Steel rod elements of the present invention and concrete slab connected node structure: at first with steel rod elements 11,12 is continuous by welding stiffener 31,32,33, then with steel rod elements 11,12 and stiffener 31,32,33 be welded on steel bearing plate 2 soffits, again with parallel placement, the corresponding two perforated panel connectors 41 of position of opening, 42 are welded on the upper surface of steel bearing plate 2 respectively, and perforated panel connector open interior can be circular port and slotted eye, as shown in Figures 2 and 3; In the hole of two perforated panel connectors 41,42, place subsequently and connect reinforcing bar 51,52,53,54,55,56, on two perforated panel connectors 41,42, pour into a mould concrete slab 6 at last and make concrete slab 6 bottoms equal with steel bearing plate 2 soffits.Realize being connected of steel rod elements and concrete slab by the perforated panel connector, adopted two perforated panel connectors to help connecting reinforcing bar position and fix, connected reinforcing bar 51,52,53,54,55,56 can improve its shearing resistance and anti-pulling bearing capacity, and the hole gap can convenient construction.
Wherein, steel bearing plate thickness, perforated panel aperture, perforate number and perforation bar diameter etc. can be adjusted according to the structure stress size, the length that connects reinforcing bar can be according to the length of reinforcing bar be definite in the same way in the connected node place concrete reinforcing cage, and the concrete shape of stiffener can be made adjustment according to the processing situation of steel rod elements.
Above-mentioned description to embodiment is can understand and apply the invention for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the invention is not restricted to the embodiment here, those skilled in the art should be within protection scope of the present invention for improvement and modification that the present invention makes according to announcement of the present invention.
