Abstract
The utility model relates to a connection structure of an outer sleeve structure beam column node and a primary structure beam column node. The connection structure of the outer sleeve structure beam column node and the primary structure beam column node comprises a strengthening node and an elastic sub-plate, wherein the outer sleeve structure beam column node expands inward toward the primary structure beam column node to form the strengthening node, and a gap is prearranged between the strengthening node and the primary structure beam column node. The elastic sub-plate is filled in the gap and is tightly pressed with the primary structure beam column node and the strengthening node. The connection form is simple in structure, the technical problem that a new building and an old building bear horizontal loads in a cooperated mode at the connection position of the outer sleeve structure beam column node and the primary structure beam column node is solved, and the connection structure of the outer sleeve structure beam column node and the primary structure beam column node can be widely applied to story-adding transformation of the old building.
Description
Technical field
The utility model relates to a kind of building engineering field old building reconstruction structure, when particularly relating to a kind of employing jacket structure form and realizing adding layer, and the syndeton between jacket structure and the original structure.
Background technology
Rapid expansion along with city size, the value in soil is more and more higher, some buildings of old town are owing to the building age is far away, the number of plies is lower, the soil can't take full advantage of, but because the overwhelming majority not yet reaches service life, if extensive the dismounting rebuild, must cause the waste of a large amount of manpower and financial resources.
In the practical operation, usually adopt jacketing frame to add layered scheme and namely keeping adding layer thereon on the motionless basis of existing building, this technical scheme can add layer generally more than three layers because new and old structure separates, and has enlarged building area, has saved land used.Old room can normally use in the adding storey for strengthening process simultaneously, has avoided extensive resettlement.As long as it is proper that structure is processed, well-designed and construction, jacketing frame adds layer technology can obtain significant effect.
Theoretically, form between original building structure and the new overcoat adding storey structure that to be articulated and connected be a kind of desirable type of attachment, but in engineering practice, the present existing mode of being articulated and connected there is no method and reaches the collaborative function of bearing horizontal loading of new and old building fully, original structure bean column node and jacket structure bean column node junction, owing to there is corner, it realizes the collaborative difficult point of bearing in the especially engineering practice of horizontal loading.
The utility model content
The utility model provides the syndeton of a kind of jacket structure bean column node and original structure bean column node, solve at original structure bean column node and jacket structure bean column node junction and realize the collaborative horizontal loading of bearing of new and old building, strengthen the technical problem of new and old building globality.
To achieve these goals, the utility model has been taked following technical scheme:
The syndeton of a kind of jacket structure bean column node and original structure bean column node, comprise and strengthen node and resilient sleeper-bearing, described reinforcement node is expanded in the original structure bean column node by the jacket structure bean column node and forms, be reserved with the slit between itself and the original structure bean column node, be plugged with resilient sleeper-bearing in the described slit, described resilient sleeper-bearing and original structure bean column node and reinforcement node compress.
Described resilient sleeper-bearing is rubber tile, plastic plate or polyurethane sheet.
The area of described resilient sleeper-bearing is not less than the area of original structure bean column node end face.
The cross section of described reinforcement node is that the jacket structure bean column node enlarges the rectangle of formation or enlarges form U-shaped to jacket structure beam below and both sides to jacket structure beam below.
Beneficial effect
Expand in the original structure bean column node by the bean column node with jacket structure, corner is connected the conversion plane to be connected, then in both slits, clog resilient sleeper-bearing, thereby the collaborative of horizontal loading born in realization, this syndeton, form of structure is simple, economical rationality, experimental project prove that implementation result is obvious.
The utility model has well solved original structure and jacketing frame at the connectivity problem at frame joint place, and original structure without any damage, has been increased the resistance to overturning of original structure and jacket structure simultaneously.All in all, the method economical and effective has broad application prospects.

Wherein: 1, resilient sleeper-bearing 2, original structure bean column node 3, jacket structure bean column node 4, rectangle are strengthened node 5, jacket structure beam
The specific embodiment
Shown in Fig. 1-2, the syndeton of a kind of jacket structure bean column node and original structure bean column node, comprise rectangle reinforcement node and resilient sleeper-bearing 1, described rectangle is strengthened node 4 and is formed to the 2 interior expansions of original structure bean column node by jacket structure bean column node 3, be reserved with the slit between itself and the original structure bean column node 2, be plugged with resilient sleeper-bearing 1 in the described slit, described resilient sleeper-bearing 1 is strengthened node 4 with original structure bean column node 2 and rectangle and is compressed.Described resilient sleeper-bearing 1 is rubber tile, plastic plate or polyurethane sheet.The area of described resilient sleeper-bearing 1 is not less than the area of the node end face of original structure bean column node 2.The cross section of described reinforcement node 4 rectangle that to be the jacket structure bean column node to jacket structure beam 5 belows enlarge forms or to jacket structure beam 5 belows and both sides enlarge form U-shaped, the U-shaped performance for both sides expansion formation that provides in the accompanying drawing 2, this situation is applicable to jacket structure beam-ends face less than the situation of jacket structure post width, for jacket structure beam and the equal situation of jacket structure post width, the general square-section form that enlarges formation to jacket structure beam 5 belows that adopts.Its concrete size is determined according to practical engineering calculation.
Operating principle of the present utility model is: strengthen node by expanding in the jacket structure bean column node to form, change the complexity connection of corner into the plane connection, the filling resilient sleeper-bearing can guarantee newly in the slit, the vertical relative displacement between the old structure do not produce distortion internal force substantially, behind the tension of prestressed tendon in jacket structure, the jacketing frame beam produces the slight compression distortion, and the compression resilient sleeper-bearing can be realized newly, old structure synergy in the horizontal direction.
More than be an exemplary embodiments of the present utility model, enforcement of the present utility model is not limited to this.
