Detailed Description
As shown in fig. 1, the concave preformed groove 2 is arranged perpendicular to the concrete wall 1, and the length × width × height is 2200 × 1800 × 60 mm.
As shown in fig. 2, the utility model discloses when constructing concrete wall 1, the both sides are injectd through wall exterior sheathing 4 and wall inner formword 5, and wall exterior sheathing 4, wall inner formword 5's combination are called wall template for short, through reserving out concrete wall spill preformed groove template supporting construction in 2 departments of spill preformed groove to realize the convenient operation in later stage, concrete wall spill preformed groove template supporting construction passes through wooden mould 3 and realizes.
As shown in fig. 3, the concrete wall concave preformed groove formwork supporting construction method includes the following steps:
s1: measurement and positioning: determining the position of the concave preformed groove 2 according to a drawing;
s2: binding concrete wall surface reinforcing steel bars;
before the steel bar is manufactured and processed, the surface is cleaned, adhered oil stain, soil and floating rust must be cleaned before use, local bending, dead bending and small wave shape are avoided, and the surface flaw cannot reduce the section of the steel bar by 5%.
The positions and the intervals of the reinforcing steel bars are arranged and bound by marking the intervals of the main reinforcing steel bars on the cushion layer during binding according to the size of a design drawing. The steel bar protection layer is made of cushion blocks made of high-grade mortar with the thickness of 50 multiplied by 35mm, and one cushion block is arranged at intervals of 1-1.5 meters and is arranged in a quincunx shape. And the side wall steel bar protection layer is ensured to meet the design and standard requirements.
The vertical reinforcing steel bars of the wallboard are finished and checked after the bottom plate reinforcing steel bars are finished. At first draw the wallboard axis on the bottom plate reinforcing bar to according to the wide (protection layer that subtracts) horizontal reinforcing bar of two rows of ligatures under the bottom plate of wall, as the control line of wall stud, on the stud inserts bottom plate lower floor's reinforcing bar, and with the horizontal reinforcement ligature of the row on the bottom plate, wherein during groove position reinforcement, outside reinforcing bar normal ligature, inboard stud and the ligature of horizontal bar outside concave yield, the concave yield degree of depth is wooden mould thickness.
S3: manufacturing a wood mold 3:
1. the wood mold 3 comprises a vertical mold 6, a side mold 10 and a keel 11, wherein the vertical mold 6 and the side mold 10 adopt bamboo plywood with the specification of length, width and thickness being 2400 mm multiplied by 1200mm multiplied by 18mm, and the keel adopts wood beam with the specification of width, thickness being 90 mm multiplied by 40 mm.
2. As shown in fig. 4, the vertical mold is spliced by 2 bamboo plywood sheets, the sizes of the vertical mold are 2200 × 1200mm in length × width and 2200 × 600mm in length × width, when the vertical mold is spliced, the width of the splicing seam 8 needs to be smaller than 2mm, the vertical mold is connected by a vertical mold connecting plate 9 with the width of 2200 × 100mm in length × width, the vertical mold connecting plate 9 is nailed on the upper sides of the two bamboo plywood sheets and is nailed by steel nails 7, and the distance between the steel nails 7 is not larger than 500 mm.
