Embodiment Construction

[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] A construction method for positioning steel bars reserved for side walls in the construction of a reverse method of the present invention includes the following construction steps:

[0046] The specific construction of the side wall reserved steel bar positioning construction method in the reverse method construction of the present invention is as follows:

[0047] 1) Excavate the earth within the boundary of the upper side wall by 30cm (that is, dig down the horizontal construction joint of the side wall by 30cm) to form an overexcavation section 11 of the side wall, such as figure 2 shown.

[0048] 2) pouring the side wall concrete cushion 12 of the side wall range at the bottom of the side wall over-excavation section 11, such as image 3 shown.

[0049] 3) Build the side wall brick membrane 13 on the side of the side wa...

Abstract

The invention discloses a positioning construction method for reserved steel bars of side walls in reverse construction. The method comprises the following steps of downwards over-excavating a side wall over-excavation section at a construction seam of an upper side wall; filling the side wall over-excavation section with a medium sand layer; fixing first multiply plywood on the medium sand layer, and forming first reserved holes; vertically inserting the reserved steel bars into the first reserved holes, and inserting and fixing the lower ends of the reserved steel bars into the medium sand layer; fixing second multiply plywood at the upper ends of the reserved steel bars, forming second reserved holes, inserting the upper ends of the reserved steel bars into the second reserved holes, and straightening the reserved steel bars; building a template of the upper side wall between the first multiply plywood and the second multiply plywood, and pouring concrete to form the upper side wall. The reserved steel bars are inserted into the upper multiply plywood and the lower multiply plywood, embedded steel bars are accurately positioned by virtue of the reserved holes formed in the multiply plywood, the operation is simple, displacement of the reserved steel bars of the upper side wall and the lower side wall is avoided, and the construction quality of the side walls is improved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method for positioning steel bars reserved for side walls in reverse construction. Background technique [0002] refer to figure 1 As shown, the existing side wall construction method is to reserve vertical steel bars 23, 24 when constructing the upper and lower section side walls 21, 22 respectively. Butt the reinforcing bars 23 and 24, construct the side wall connection section between the upper and lower side walls, and complete the side wall construction. Adopting this kind of construction, the upper and lower reserved vertical steel bars 23, 24 are easy to be misplaced, and the positioning is not accurate, which leads to difficulties in the butt joint of the vertical steel bars, affects the connection quality of the side wall reinforcement, affects the quality of the side wall, and also affects the construction progress.
