Abstract
The utility model discloses a frame bridge inducing joint structure and provides an inducing joint structure that is positioned in the frame bridge. Problem of concrete crack due to the stress generated by a long box body jacking the frame, and water seepage from a frame seam can be solved. The utility model belongs to the technical field of jacking construction. The frame bridge inducing joint structure comprises an inducing joint positioned in the frame bridge. A joint plate (7) is arranged inside the inducing joint. A plurality of steel shear pins (5) which are arranged along length direction of the frame are alternately positioned on both sides of the wall of the frame of the inducing joint along the height direction of the frame. The steel shear pins (5) pass through the joint plate (7). Water proof layers are arranged on the outside of the top tray of the inducing joint frame, on outside of two lateral walls, and inside the frame respectively. The frame bridge inducing joint structure is simple in structure, and the phenomenon that a plurality of cracks appear in the frame structure under the effect of concrete stress is effectively improved. Accumulated jacking deviation caused by a plurality of frames jacking by several times is greatly reduced, project quality is greatly improved, time limit for a project is greatly shortened, and construction cost is reduced.
Description
Technical field
The utility model relates to a kind of frame bridge and induces crack structure, and specifically a kind of crack structure of inducing that improves long box-body jacking frame concrete stress crack and framework joint seam crossing infiltration phenomenon in the frame bridge that is arranged on belongs to the Construction Technology of With standing Operation field.
Background technology
During the framework jacking construction, if the jacking lengths of frame is long, normally minute more piece is taked the jacking of relay well method after prefabricated, needs the long construction period like this, and the jacking number of times increase after then the jacking Accumulated deviation increase; Perhaps adopt framework whole elongated prefabricated, though can shorten the construction period like this, frame construction can occur than multiple cracking because of the concrete stress impact, and quality can not guarantee.Be to establish settlement joint together every about 5～10m on framework, though can improve structural cracks like this, it is bad that framework saves the seam crossing stagnant water effect, can't thoroughly solve seepy question in the past, of long duration the phenomenon that seeps water will occur.
Summary of the invention
For the defects that exists in the prior art, the utility model provides a kind of frame bridge to induce crack structure, and effectively solution framework divides that the multistage prefabricated construction is long in time limit, repeatedly jacking causes the jacking Accumulated deviation to increase, problem than multiple cracking, framework joint joint seal weak effect can occur because of the concrete stress impact.
The utility model is achieved by the following technical solution: a kind of frame bridge is induced crack structure, it comprises the seam of inducing that is arranged in the frame bridge, described inducing is provided with joint filling board in the seam, being interval with some steel along the setting of lengths of frame direction along the frame height direction within the walls at described framework dual-side of inducing the seam place cuts off, described steel cuts off and passes described joint filling board, is respectively equipped with waterproofing course in the described inboard of the top board outside, the both sides abutment wall outside and the framework of the framework at seam place of inducing.
In the utility model, be located at steel in the seam and cut off and can guarantee that framework induces the stability of crack structure in jacking, and the vertical shear strain of controlled framework bridge, the design of waterproofing course can effectively guarantee to induce seam water-tight.Frame bridge can effectively prevent the crack that occurs because of the concrete stress impact by the above-mentioned crack structure of inducing is set.
In order to improve the stagnant water effect of inducing the seam place, the described outside of inducing seam to be in the framework reinforcing bar also is embedded with along inducing the seam place to form the steel limit waterstop of closed loop, is embedded with in the frame concrete at described seam guide place along inducing the seam place to form the rubber fastening band of closed loop.
Further scheme is, described steel limit waterstop is GSE5 section steel edge waterstop, and described rubber fastening band is GRE7 type rubber fastening band.
In order to improve waterproof effect, described waterproofing course is included in the top board outside of framework and polyurethane water-proof paint layer and the Chlorinated polyethylene plastic sheets for waterproofing layer that the abutment wall outside in both sides sets gradually from the inside to the outside, and the M1500 waterproof agent layer of brushing in the inboard of framework.
It is that the ferule of 30mm and round steel that diameter is φ 28mm consist of that described steel cuts off by internal diameter, and described round steel is inserted in the described ferule, is filled with the pitch ointment in the described ferule.
Described joint filling board is to be fixedly installed on the hard wood particle board of inducing seam middle.
The setting space that described steel cuts off is 20cm.
The beneficial effects of the utility model are: the utility model is simple in structure, simple to operate, it is arranged in the framework, effectively improved frame construction because being subjected to concrete stress to affect the more cracky phenomenon of appearance, greatly reduced the accumulative total jacking deviation that multi-section frame gradation jacking produces, improved workmanship, and reduction of erection time greatly, reducing construction cost.
