Abstract

The invention discloses a construction method for a folding type structural slab post-cast strip joint formwork. The construction method includes the following steps that firstly, a structural slab forming formwork is erected, and specifically, the forming formwork for a constructed structural slab is erected; secondly, a bottom layer reinforcing mesh is bound; thirdly, a post-cast strip joint formwork is arranged, specifically, the post-cast strip joint formwork comprises a plurality of assembled formwork bodies, each assembled formwork body comprises a left lateral formwork body and a right lateral formwork body symmetrical with the left lateral formwork body, and each lateral formwork body comprises a foldable formwork body and a formwork connecting structure mounted on the foldable formwork body; fourthly, a surface layer reinforcing mesh is bound; fifthly, the post-cast strip joint formwork is erected; sixthly, concrete is poured, and specifically, the constructed structural slab is subjected to concrete pouring through the forming formwork and the post-cast strip joint formwork; and seventhly, the post-cast strip joint formwork is removed. The steps of the construction method are simple, the design is reasonable, construction is easy and convenient, the using effect is good, the construction process for the structural slab with a reserved post-cast strip can be completed easily, conveniently and rapidly with high quality, and the construction quality is easy to guarantee.

Description

technical field

[0001] The invention belongs to the technical field of post-cast belt construction, and in particular relates to a construction method for a folded structural plate post-cast belt joint formwork. Background technique

[0002] The post-pouring strip is a temporary part set at the corresponding positions of the foundation floor, wall and beam in order to prevent the harmful cracks that may occur in the cast-in-place reinforced concrete structure due to uneven shrinkage or uneven settlement during construction. construction joints. When supporting the post-cast strip formwork, in addition to meeting the requirements of tightness and firmness, it should also meet the requirements of easy removal of the formwork. However, the traditional post-cast belt formwork support method currently adopted is to use wooden formwork support or steel wire mesh to block the construction process. The construction process is relatively cumbersome, and the materials such as wood fo...

Embodiment Construction

[0057] Such as figure 1 The construction method of a folded structural slab post-casting joint formwork shown includes the following steps:

[0058] Step 1. Supporting of the forming formwork of the structural slab: supporting the forming formwork of the constructed structural slab; the forming formwork includes a bottom formwork 13 supported under the constructed structural slab and a side formwork arranged on the bottom formwork 13 The constructed structural slab is a cast-in-place reinforced concrete slab that is laid horizontally, and the bottom template 13 is laid horizontally, see figure 2 ;

[0059] The cast-in-place reinforced concrete slab is provided with a bottom reinforcement mesh and a surface layer reinforcement mesh above the bottom reinforcement mesh, the bottom reinforcement mesh and the surface layer reinforcement mesh are arranged horizontally and both are formed by The vertical horizontal steel bars are bound with multiple horizontal horizontal steel bar...
