摘要:
An end face (20) of one (10a) of two adjacent thick steel plates (10a, 10b) intended to construct a corner joint of a bridge column is formed into a beveled end face (22). Laser beam welding is applied to a root portion (24) of the beveled end face, and arc welding is applied to bevels (26, 28) thereof so that grooves defined by the bevels (26, 28) are filled with weld metal (40).
摘要:
A guideway structure for the high-speed track-bound transportation is composed of the lower-layer main load-bearing girders and the guideway-surface structure elements. The structural elements are connected by the steel elements at the functional zones and the reinforced concrete plates on the guideway body to form an integral. The guideway structure has the following special features:
(1) The reinforced concrete plate girders are elements of small-size type. Many of the reinforced concrete plate girders are longitudinally disposed on the lower-layer main load-bearing girders along the guideway line; Between two adjacent reinforced concrete plate girders is reserved a gap of certain width for expansion and contraction; (2) The said connection-mechanism is composed of the supporting steel girders, the weld nails, the high strength bolts and the steel bearing plates. The supporting steel girders are connected with the lower-layer main load-bearing girder by the high strength bolts, the steel bearing plates and the connecting steel plates; The weld nails are on the top of the supporting steel girder and deeply inserted into their respective post-poured holes on the reinforced concrete plate girder; The connection will be completed by pouring concrete on-site after the reinforced concrete plate girder has been accurately positioned; (3) In the case of double-track guideway, between the lateral surfaces of both lower-layer main load-bearing girders are disposed cross beams for supporting purposes.
The invention is one of the guideway structures especially suitable for the guideway structure across a river of medium- or small-width.
摘要:
A method of making a reinforced structure of the type including a body of solidified matrix material, for example a cement based material, and reinforcing elements embedded therein, said method comprising shaping and solidifying matrix material so as to form a plurality of matrix body members (10) which when arranged adjacent to each other form a matrix body with a plurality of elongated cavities (11/12) therein, at least one of the matrix body members having matrix reinforcement components incorporated therein, at least one of the elongated cavities being formed on an interface between matrix body members when arranged adjacent to each other and/or at least two of the elongated cavities being formed transversely to each other and each intersects an interface between matrix body members arranged adjacent to each other, arranging the matrix body members adjacent to each other with reinforcing elements (13, 14, 15) within the said cavities, and interconnecting the matrix body members and the reinforcing elements so as to form said reinforced structure. Reinforced structures made by that method, and a kit of parts for use in that method are also claimed.
摘要:
The present invention relates to a prefabrication type high level road structure, comprising :
an underground section (2) for stably supporting the total weight of the high level structure and vehicles thereon and for distributing the corresponding total weight ; and a support section (4) comprising a plurality of supports (400,420) spaced-apart from one another by a predetermined distance and vertically standing on a road on which the high level road is constructed, and a plurality of cross-beams (412) provided on the upper portions of the supports for supporting a pavement section.
This structure is characterized in that :
the underground section (2) comprises basic members (200) forming two parallel rows extending along the center line of the road, at least one steel frame (204,206) located in the space formed between the basic members, and concrete poured in said space for burying the steel frame, the supports (400,420) being rigidly connected to the assembly comprising the basic members, steel frame and concrete.
