Abstract
The invention discloses an L-shaped connecting node of a fully-prefabricated reinforced concrete structural beam, which comprises a first beam groove and a second beam groove. The L-shaped connecting node is characterized in that concretes on the inside walls of the corners of the first beam groove and the second beam groove are not connected, and the concrete inside the corner is a cast-in-placeconcrete; a horizontal reinforcement bar inside the first beam groove extends forwards, bent to 90 degrees in the outside of the corner of the node, then extends into the cast-in-place concrete, and stops in the cast-in-place concrete; a horizontal reinforcement bar inside the second beam groove extends forwards, bent to 90 degrees on the outside of the corner of the node, then extends into the cast-in-place concrete, and stops in the cast-in-place concrete; and an additional reinforcement bar on the upper part of a first L-shaped beam and an additional reinforcement bar on the lower part of the first L-shaped beam are positioned in the first beam groove and the cast-in-place concrete, and the same side of the corner and the second beam groove has a seam . The L-shaped connecting node canconnect the first beam groove and the second beam groove to form a whole, bear and transfer external forces in the vertical and horizontal directions, and ensure the safety of buildings.
Description
Technical field
The present invention relates to a kind of steel reinforced concrete full-prefabricated assembly structural beam L type connected node, belong to the building structure technology field.
Background technology
In building structure, Liang Yuzhu is the main supporting member in the building, the ability that its opposing destroys more, especially anti-seismic performance is the important indicator of Liang Yuzhu, to be connected be common a kind of connected mode in the corner between steel reinforced concrete full-prefabricated assembly structural beam and the beam, and the connected mode at node place has a variety of, but complex structure all mostly, the work progress complexity, or anti-seismic performance is not strong.
Summary of the invention
Technical problem to be solved by this invention provides a kind of structural beams corner that makes and is connected to integral body and steel reinforced concrete full-prefabricated assembly structural beam L type connected node simple in structure, that the external force resistance ability is strong.
For solving the problems of the technologies described above, the invention provides a kind of steel reinforced concrete full-prefabricated assembly structural beam L type connected node, comprise the first beam groove and the second beam groove, it is characterized in that: the inside wall concrete of the described first beam groove and the second beam groove corner does not link to each other, on the corner inboard is cast-in-situ concrete, the horizontal reinforcement of the described first beam groove inboard extends forward and stretches in the cast-in-situ concrete behind 90 ° of the lateral bucklings outside the node corner, and terminate in the cast-in-situ concrete, the horizontal reinforcement of the described second beam groove inboard extends forward and stretches in the cast-in-situ concrete behind 90 ° of the lateral bucklings outside the node corner, and terminate in the cast-in-situ concrete, the one a L type beam top additional bar and a L type beam bottom additional bar are positioned at first beam groove and the cast-in-situ concrete, the 2nd L type beam top additional bar and the 2nd L type beam bottom additional bar are positioned at second beam groove and the cast-in-situ concrete, on the corner have a seam with the second beam groove homonymy.
The beneficial effect that the present invention reached:
Steel reinforced concrete full-prefabricated assembly structural beam L type connected node of the present invention, at the node place with the reinforcing bar interlaced arrangement in two vertical structural beam, and connect into the first beam groove and the second beam groove as a whole by cast-in-situ concrete, can bear and transmit the external force that vertically reaches horizontal direction, guarantee the safety of building.
