Description

Novel basement outer wall post-cast strip construction device

Technical Field

The utility model relates to the field of building construction, in particular to a novel basement outer wall post-cast strip construction device.

Background

The post-cast strip for construction is divided into a post-cast settlement strip, a post-cast shrinkage strip and a post-cast temperature strip, and is respectively used for solving the problems of differential settlement between a high-rise main building and a low-rise skirt house, the difference of the shrinkage deformation of reinforced concrete and the small temperature stress. The post-cast strip generally has the functions of various deformation joints, and one function is considered as the main function and other functions are considered as the auxiliary functions during design. The post-cast strip for construction is a whole building, and comprises reserved seams (the seams are wide and are called as strips) in foundation and structure construction, after the main body structure is completed, the post-cast strip concrete is filled, the seams do not exist, the differential settlement of a high-rise main building and a low-residential skirt house is solved in the whole structure construction, and the purpose of not setting a permanent deformation seam is achieved.

For a long time, the construction of the inner structure of the outer wall of the basement has the phenomenon of time limit for construction periods of different degrees due to the existence of a plurality of restriction factors such as construction organization and the like. Particularly, when the wall body formwork at the post-cast strip is erected, the situation that the lateral common wood formwork of the post-cast strip cannot be smoothly erected due to the blocking of the steel bars in the wall is frequently encountered. Construction team often compels to adopt steel wire net piece or other flexible material to replace the plank sheathing and carries out simple shutoff, form the hourglass thick liquid phenomenon often in steel sheet net department after concrete placement vibrates, finally lead to template and steel sheet net demolish the back, the concrete surface of post-cast strip department is uneven, the both sides concrete is closely knit or even appears the dog hole, and then lead to the construction unit later stage to put into a large amount of manpower and materials and carry out the secondary and repair, even follow-up operation period causes the outer wall seepage from hereon in closely knit region, the serious thing influences the phenomenon of structural entity intensity even. The labor cost and the construction period delay are high, and the construction unit can feel the misstatement. How can just accomplish basement outer wall post-cast strip department template fast, effectual and prop up and establish, guarantee the concrete quality after the form removal simultaneously, avoid later stage seepage or repair, be the construction difficult problem that needs to solve at present urgently.
