Construction method of sole plate post-poured strip form bracing system

Abstract

The invention discloses a sole plate post-poured strip form bracing system, applicable to sole plate post-poured strip form bracing of basement in constructional engineering. The form bracing system is mainly composed of components of a steel screen mould, a cable-stayed bolt and structural steel back plank, a precast slurry baffle concrete strick and a slurry baffle wood block. The invention utilizes a sole plate reinforcing mattress as a main bracing body, side pressure of concrete at the two sides of the post-poured strip can be effectively braced, the cavity of the formed post-poured strip is clean, tidy and clear and has no concrete pouring oozing or laitance pollution, most materials in the post-poured strip form bracing system are available and can be dismantled and recycled, and design function of post-poured strip can be effectively realized.

Description

Technical field: [0001] The invention relates to a construction technology of civil engineering and construction engineering, which is a construction method of a post-cast belt formwork support system for a foundation base plate. Background technique: [0002] The post-pouring belt construction formwork support material of the foundation base plate has no other function except to form the cavity of the post-casting belt. Generally, the post-cast belt formwork support of the foundation base plate adopts steel mesh formwork, and the post-cast belt support material is difficult to remove, and is generally left in the post-cast belt, and the formwork support material is a one-time consumption; The grout leakage in the gap of the protective layer of the steel bar will cause pollution to the cavity of the post-cast belt. Generally, mortar is used to block it or a cast-in-place plain concrete grout strip is arranged before the reinforcement of the foundation floor is bound. After t...

Generally, the post-cast belt formwork support of the foundation base plate adopts steel mesh formwork, and the post-cast belt support material is difficult to remove, and is generally left in the post-cast belt, and the formwork support material is a one-time consumption; The grout leakage in the gap of the protective layer of the steel bar will cause pollution to the cavity of the post-cast belt. Generally, mortar is used to block it or a cast-in-place plain concrete grout strip is arranged before the reinforcement of the foundation floor is bound. After the cavity of the post-cast belt is formed, the mortar or plain It is difficult to clean the concrete strips, which will affect the construction quality of the closed construction of the subsequent post-casting strips
