Embodiment 2

[0061] This embodiment is further defined on the basis of embodiment 1, as image 3 , 4 As shown, the step (5) processes Type II inner braces, which are positioning tools for fixing the distance between two layers of steel mesh and include single-control inner braces and double-control inner braces, single-control inner braces The inner support bars include support bars 7 and inner control points 8, and the double-control inner support bars include support bars 7, inner control points 8 and outer control points 9. The single-control inner support bars are bound and fixed in the wall, and the double-control inner support bars are bound to The horizontal bars are attached to the top of the wall to prevent the lateral displacement of the horizontal steel bars on the top wall when the concrete is poured. The supporting bars of the Type II inner bars can be made of Φ10-12 round steel according to the wall thickness. The length is the wall thickness minus 2mm, and the wall is horizo...

Embodiment 3

[0063] This embodiment is further defined on the basis of the above embodiments, the protective layer block is cement mortar block or plastic block, the cement mortar block is U-shaped, easy to fix, not easy to slip off and accurate in size, suitable for horizontal And the control of the protective layer of vertical steel bars, different specifications of pads are used for different protective thicknesses.

[0064] The above-mentioned construction technology can control the displacement of vertical steel bars. The specific inspection standards are as follows:

[0065] Measure the position, spacing and thickness of the protective layer of the steel bars. The detection error of the steel bar protective layer thickness is not greater than 1mm, and the detection error of the steel bar spacing is not greater than 2mm.

[0066] The inspection method is:

[0067] The inspection method for the location and spacing of steel bars: Arrange the HRB335 steel bars on a horizontal table wit...

Abstract

The invention discloses a process for positioning and constructing reinforced concrete for high-rise residential buildings. The process includes steps of (1), machining protective layer positioning braces of reinforcing steel bars of frame columns; (2), machining positioning stirrups of the frame columns; (3), machining vertical ladder ribs and horizontal ladder ribs of walls; (4), machining vertical reinforcing steel bar positioning clamps of shear walls; (5), machining type-II inner brace ribs; (6), constructing reinforcing steel bar protective layers of control beams and plates; (7), binding and constructing reinforcing steel bars. The process has the advantages that the problem of displacement of vertical reinforcing steel bars can be effectively solved by the aid of measures for specially manufacturing the protective layer positioning braces of the reinforcing steel bars of the frame columns and the positioning stirrups and the like; the purpose of effectively controlling the thicknesses of the reinforcing steel bar protective layers of the cast-in-site walls and the plates can be achieved by the aid of measures for adding the ladder ribs and the vertical reinforcing steel bar positioning clamps of the walls, manufacturing and mounting horse-shaped stools for strip-shaped reinforcing steel bars of the cast-in-situ plates, arranging plastic spacers for reinforcing steel bars of bottom plates of the cast-in-situ plates and the like.

Description

technical field [0001] The invention belongs to the technical field of high-rise residential building construction, and in particular relates to a reinforced concrete positioning construction process for high-rise residential buildings. Background technique [0002] Reinforcement engineering construction is an indispensable and important part of construction engineering. For the whole process, the quality control of reinforcement engineering is one of the key points of engineering quality control. The construction site is narrow, the diameter of the steel bar is thick, the reinforcement is large, and the steel bars at the joints of the components are dense and difficult to handle. It is difficult to cut the steel bar and bind it on site, which brings certain difficulties to the construction. [0003] If the position of the steel bars of the reinforced concrete members is placed incorrectly or the protective layer of the steel bars is too large, the bearing capacity of the re...
