Abstract
The invention discloses a steel sheath type steel truss web node structure. Two truss web steel tubes, a horizontal steel plate and slant steel sheaths are arranged on a node; the horizontal steel plate is parallel to a top plate or a bottom plate; two elliptic holes are formed on the horizontal steel plate; two slant steel sheaths are inserted and welded in the elliptic holes; the two truss web steel tubes are inserted into the slant steel sheaths respectively in the traverse direction; the two truss web steel tubes are inserted into the slant steel sheaths respectively opposite to each other in a herringbone form; intersection parts are vertically cut respectively; cut surfaces are welded with steel plates respectively to be sealed; bolt holes and through reinforcement holes are reserved on the steel plates; and the steel plates of the two steel tubes are riveted together through common bolts to ensure that the two truss web steel tubes are integrated in the traverse direction.
Description
Technical field
The invention belongs to the civil structure field, be specifically related to be used for a kind of purlin abdomen steel pipe and the concrete joint structure of steel purlin abdomen combination box beam bridge.
Background technology
Steel purlin abdomen prestressed concrete composite beam bridge is a kind of novel combination structural bridge; Replace the concrete web in the concrete box girder at textural employing purlin formula steel web member; The web ends node directly is mounted in the concrete flange plate, form by concrete roof, purlin abdomen steel pipe, concrete floor, external and (or) the cooperative combined structure system of prestressing with bond steel bundle.
In China, such bridge type still is at the initial stage, on design and research with big gap is arranged in the world.And purlin abdomen steel pipe and concrete node are one of stressed key positions of the type bridge construction.The steel purlin uromere point structural form that does not also have a kind of own intellectual property at present in China.Therefore, the wide steel purlin uromere point structure of effective, the easy construction of a kind of more power transmission of research and development, engineering adaptability is to the construction that develops China's steel purlin abdomen combination box beam bridge and promote significant.
. summary of the invention
But the present invention is directed at present external main steel purlin uromere point and be configured in the shortcoming that aspects such as stress performance and application property exist, from simplified construction, be convenient to construct, improve aspect such as stress performance and proposed a kind of novel bushing type steel purlin uromere point and construct.
The technical scheme that realizes the object of the invention is:
The steel sheath form
SteelPurlin uromere point structure, the node place is provided with two purlin abdomen steel pipes, horizontal steel plate and oblique steel sheaths; Said horizontal steel plate is parallel with top board or base plate, opens two ellipse holes on the horizontal steel plate, in the hole, inserts and weld two oblique steel sheaths; At direction across bridge; Said two purlin abdomen steel pipes insert oblique steel sheath respectively, are " people " font and are provided with in opposite directions, and vertically cut respectively the intersection; Cut surface welding steel respectively seals; Prepared screw-bolt hole and run through reinforced hole on the steel plate, the steel plate of two steel pipes is riveted together through plain bolt, and two purlin abdomen steel pipes are connected as a single entity at direction across bridge.
As further improvement of the present invention, said horizontal surface of steel plate also is provided with the weldering nail, guarantees to be connected with roof and floor is concrete.
As further improvement of the present invention, fill epoxy mortar or the high cement mortar that flows between said oblique steel sheath and the purlin abdomen steel pipe, to guarantee closely knit and the adjustment construction error.
As further improvement of the present invention, surperficial roughening processing is all done in the outside in the said oblique steel sheath, to reduce interface sliding.
The invention has the beneficial effects as follows:
(1) steel sheath form joint structure welding capacity is few, and the scene does not need welding;
(2) steel sheath form joint structure bearing capacity and rigidity are higher, can effectively transmit node moment of flexure and horizontal shear;
(3) convenient site operation, simple to operate;
(3) between oblique steel sheath and purlin abdomen steel pipe, fill epoxy mortar etc. and can adjust construction error.
Description of drawings
Fig. 1 is the vertical cross section structural representation of the embodiment of the invention 1;
Fig. 2 is the sectional view of the embodiment of the invention 1 at Figure 1A-A place.
The specific embodiment
Further specify below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1, the steel sheath form
SteelPurlin uromere point structure, the node place is provided with two purlin abdomen steel pipes 1, horizontal steel plate 2 and oblique steel sheaths 3; Horizontal steel plate 2 is parallel with roof and floor, and two purlin abdomen steel pipes 1 extend through respectively in the oblique steel sheath 3 on the horizontal steel plate.Fill epoxy mortar or the high cement mortar 7 that flows between oblique steel sheath 3 and the purlin abdomen steel pipe 1, to guarantee closely knit and the adjustment construction error.Surperficial roughening processing is all done in the outside 8 in the oblique steel sheath, to reduce interface sliding.Be embedded into the purlin abdomen steel pipe 1 in the roof and floor concrete;, being " people " font and being provided with in opposite directions, vertically cut respectively the intersection; Cut surface welding steel 4 respectively seals; Prepared screw-bolt hole and run through reinforced hole on the steel plate 4, the steel plate 4 of two steel pipes is riveted together through plain bolt 5, and two purlin abdomen steel pipes are connected as a single entity at direction across bridge.
As shown in Figure 2, on horizontal steel plate 2, opening two has ellipse hole 20, is used for inserting and welding two oblique steel sheaths 3.Welding weldering nail 6 guarantees to be connected with roof and floor is concrete on the horizontal in addition steel plate 2.Fill epoxy mortar or the high cement mortar 7 that flows between oblique steel sheath 3 and the purlin abdomen steel pipe 1.
Manufacturing process of the present invention is following: at first carry out the processing of horizontal steel plate 2 and oblique steel sheath 3 in factory, and welding weldering nail 6 on the horizontal steel plate 2, oblique steel sheath 3 carries out welding processing with horizontal steel plate 2 in factory.During site operation two purlin abdomen steel pipes 1 are located in oblique steel sheath 3; Connect with the half elliptic steel plate of bolt 5 the vertical end of abdomen steel pipe, two purlins; And, between oblique steel sheath 3 and purlin abdomen steel pipe 2, fill epoxy mortar 7 at last along indulging bridge to running through reinforcing bar 9.
Claims (4)
1. uromere point structure in steel sheath form steel purlin is characterized in that the node place is provided with two purlin abdomen steel pipes, horizontal steel plate and oblique steel sheaths; Said horizontal steel plate is parallel with top board or base plate, opens two ellipse holes on the horizontal steel plate, in the hole, inserts and weld two oblique steel sheaths; At direction across bridge; Said two purlin abdomen steel pipes insert oblique steel sheath respectively, are " people " font and are provided with in opposite directions, and vertically cut respectively the intersection; Cut surface welding steel respectively seals; Prepared screw-bolt hole and run through reinforced hole on the steel plate, the steel plate of two purlin abdomen steel pipes is riveted together through plain bolt, and two purlin abdomen steel pipes are connected as a single entity at direction across bridge.
