Abstract
The utility model relates to a basement post-cast strip force transmission device which comprises two I-shaped steel bars and steel plates. The basement post-cast strip force transmission device is characterized in that the two I-shaped steel bars are respectively and symmetrically pre-buried in a main girder along a post-cast strip of a basement main structure, one portion of each I-shaped steel bar is pre-buried in the main girder, the other portion of each I-shaped steel bar is exposed on the post-cast strip, when basement main structure concrete reaches design strength, the upper side and the lower side of the portion, exposed on the post-cast strip, of each I-shaped steel bar are respectively provided with one steel plate in a welding mode, so that the two I-shaped steel bars are connected into a whole, and floor boards are connected into a whole through force transmission strips so as to support a foundation trench enclosed structure. The basement post-cast strip force transmission device is used for force transmission of the basement main structure and is stable and reliable, overall force receiving performance of the basement main structure is good, the construction difficult problem that the basement main structure serves as a foundation trench inner support after an inner support is detached in the process of basement structure construction is solved successfully, meanwhile, cost is reduced, and the basement post-cast strip force transmission device has a good application prospect.
Description
Technical field
The utility model relates to basement agent structure power transmission field, is specifically related to a kind of basement post-pouring zone load transfer device.
Background technology
In the basement main structure construction process, every layer of basement floor all is divided into several by the ater-casting, is unfavorable for after this layer support replacement the support of pit maintenance soil structure, load transfering strip is set at the place, ater-casting floor is connected jointly enclosed structure is supported.Load transfering strip arranges in the floor girder position along the ater-casting.
The utility model content
The purpose of this utility model provides a kind of basement post-pouring zone load transfer device, this device is reliable and stable, make basement agent structure holistic resistant behavior good, success solves in the basement structure construction process, support the back in removing and serve as the construction difficult problem that supports in the foundation ditch by the basement agent structure, reduce cost simultaneously, good application prospects is arranged.
The utility model is achieved through the following technical solutions:
The basement post-pouring zone load transfer device, comprise two i iron and steel plate, it is characterized in that: two i iron are embedded in respectively symmetrically along in the girder of basement agent structure ater-casting, and an every i iron part is embedded in the girder, another part is exposed at the place, ater-casting, after treating that basement agent structure concrete reaches design strength, two i iron that are exposed at the place, ater-casting respectively weld a block plate up and down two i iron are linked into an integrated entity, and the formation load transfering strip is connected floor and jointly the pit maintenance soil structure is supported.
In technique scheme, the thickness of steel plate is 12mm～20mm.
The beneficial effects of the utility model are: power transmission is clear and definite, and is stressed reasonable, improves basement agent structure holistic resistant behavior.I iron and steel plate processing and fabricating are easy, are beneficial to scale processing.
