Abstract
Disclosed is an outer sleeved frame story adding structure accepting a cushion block. The outer sleeved frame story adding structure comprises an original frame column, an outer sleeved frame column and a pulling device. The pulling device comprises pulling rebar, an anchoring steel plate and a limiting cushion block. The anchoring steel plate is arranged on an opposite face of the original frame column and the sleeved frame column. The pulling rebar is arranged in at least two layers. Each pulling rebar penetrates through the anchoring steel plate and the original frame column in sequence, and stretches into the outer sleeved frame column, and then is anchored. An end head, extending out of the anchoring steel plate, of the pulling rebar is fixed through an anchoring nut. The limiting cushion block is stuffed in the space formed between the original frame column and the outer sleeved frame column by two layers of connecting rebar and clamped with the connecting rebar, the original frame column and the outer sleeved frame column in a limiting mode. The outer sleeved frame story adding structure achieves that horizontal force is bore by the original frame column and the outer sleeved frame column together, an old and a new building are stressed synergistically, and integrity of the original frame column and the outer sleeved frame column is greatly increased. The outer sleeved frame story adding structure can be widely applied to story adding structures.
Description
Technical field
The utility model relates to the old building renovation technique field in a kind of building structure, especially adopts jacketing frame to add the old building renovation technique field of layer.
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 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 at present.
The utility model content
The purpose of this utility model is to overcome the deficiency of traditional syndeton, for solving better the connectivity problem of jacketing frame and original building structure, provides a kind of simple in structure, economical rationality, actual effectively optimizing design scheme.
To achieve these goals, the utility model has been taked following technical scheme:
A kind of jacketing frame adding storey structure of having used cushion block, comprise former frame column, jacketing frame post and drawknot device, described drawknot device comprises steel tie, anchor plate and limiting cushion block, described anchor plate is arranged on former frame column and the jacketing frame post deviates from face, described steel tie divides two-layer setting at least, every steel tie passes successively anchor plate and former frame column stretches into anchoring in the jacketing frame post, described steel tie exposes the termination of anchor plate to be fixed by the anchoring nut, described limiting cushion block is filled in the space that two-layer connecting reinforcement forms between former frame column and jacketing frame post, and and connecting reinforcement, former frame column and the spacing chucking of jacketing frame post.
Described limiting cushion block is block rubber, spring block, rubber spring piece or elastic polyurethane piece.
The width of described limiting cushion block is greater than the distance between two steel ties in the same plane, and it highly equals the clear distance between vertical corresponding two steel ties.
Described steel tie is straight reinforcing bar or U-shaped bending reinforcing steel bar, and the bending segment of U-shaped bending reinforcing steel bar is positioned at the jacketing frame post.
The utlity model has following technique effect:
By between former frame column and jacketing frame post, flexible limiting cushion block being set, and by the steel tie of cooperative bearing former frame column and jacketing frame post are carried out drawknot, realized the shared horizontal force between former frame column and the jacketing frame post, make new and old building realize cooperative bearing, greatly strengthened the globality of former frame column and jacketing frame post.
Adopt above-mentioned optimal design, well solved the connectivity problem of original structure and jacketing frame, original structure is destroyed seldom, increased the resistance to overturning of structure.All in all, the method economical and effective has broad application prospects.
