Construction method of template with no split bolt hole

Abstract

The invention discloses a construction method of a template with no split bolt hole. The construction method includes the following steps: (1) sequentially placing a plurality of external wall templates along the longitudinal direction to form a lower-layer external wall template; (2) placing small template strips and split bolts at the top of the lower-layer external wall template at intervals; (3) repeating the step (1) and the step (2) to construct upper-layer external wall templates layer by layer until the upper-layer external wall templates are as high as the installation of the external wall templates; (4) installing a vertical wood square on the outer sides of the external wall templates; (5) installing horizontal double steel pipes arranged along the horizontal direction on the outer side of the vertical wood square; (6) adjusting the evenness and verticality of the external wall templates; (7) pouring wall concrete; (8) loosening the split bolts when the wall concrete achieves the template removing strength, taking down the double steel pipes, dismantling the external wall templates and removing the small template strips; (9) cutting off the exposed portion of the split bolts at the bottom of a groove formed at the position where the small template strips are removed; and (10) trowelling the groove through waterproof mortar. By means of the construction method, rigidity of the template is reliable.

Description

technical field [0001] The invention relates to a construction method of a wall column formwork, in particular to a construction method of a basement exterior wall using a wooden formwork. Background technique [0002] Among the current reinforced concrete structural members, concrete walls account for a large proportion, and most of the concrete walls are still constructed with wooden formwork. Using wooden formwork to construct wall formwork, usually according to the formwork construction plan generally adopts pull bolts, and the bolt spacing is generally 400-600mm, so bolt holes must be set on the wall formwork when using to ensure the distance between pull bolts to meet the construction plan Formwork support system in the demand for formwork stiffness. In order to reduce the number of bolt holes set on the building formwork, during the design process of the formwork construction plan, the distance between the tension bolts and the wood squares need to be carefully calcu...

Problems solved by technology

[0003] The above common practice still needs to set bolt holes on the building formwork, resulting in a reduction in the number of formwork turnover. The formwork with bolt holes can only be used in the construction of wall and column formwork after the turnover, and a large amount of new formwork still needs to be invested in the beam and slab formwork.
