Embodiment 1

[0020] basically as attached Figure 1-Figure 2 shown.

[0021] The construction method of fair-faced concrete for the beamless floor slab with special-shaped curved surface includes the following steps:

[0022] A. Modeling design, using Auto CAD and Rhino software for simulation design. The bearing capacity calculation is carried out by the safety calculation software of Pinming.

[0023] B. Set out lines, carry out three-dimensional lofting, and use laser points for projection construction. As a result, through the three-dimensional lofting, it is possible to perform fine lofting for the irregularly-shaped curved surface. On the rhino 1:1 three-dimensional solid model, the corresponding elevation of each required node is cut horizontally to form a plan view, the coordinates of the control point are picked up, and a high-precision total station is used for stakeout and control.

[0024] C. Template installation, taking some templates as an example, combined with Figure...

Embodiment 2

[0033] combine figure 1 As shown, a pipe frame 19 is slid on the top of the plate body 8 along the upper surface of the plate body 8. The specific sliding method is as follows: the top of the plate body 8 is provided with a chute, and the pipe frame 19 is welded with a pipe frame 19 located in the chute. slider. The pipe frame 19 is provided with a nozzle 18, and the nozzle 18 is provided with bristles. The bottom of the spray pipe 18 is provided with a liquid outlet hole, and the inside of the spray pipe 18 is provided with a release agent. In this way, in step D, by sliding the pipe rack 19, the pipe rack 19 drives the nozzle 18 to move, and the bristles move on the top of the plate body 8, so that the release agent is brushed on the top of the plate body 8 in a large area, and the operation is simple convenient.

Abstract

The present invention relates to the field of concrete construction, in particular to a construction method for fair-faced concrete with special-shaped curved surface beamless slabs, comprising the following steps: A. Modeling and design, B. Laying out, C. Formwork installation, D. Applying formwork release agent, E, install steel bars, F, pour concrete, G, maintain and remove formwork, H, apply protective agent as a whole, the formwork in step C includes a plate body and a plurality of bumps, the inside of the plate body is provided with a liquid chamber, and the plate body There is a bump chamber connected to the liquid chamber on the surface, and the bump slides in the bump chamber; in step D, before applying the release agent to the template, the bump is placed in the bump chamber, and the top of the bump is in contact with the plate The top of the body is flush, and then apply a release agent to the top of the plate body and the top of the bump, and then slide the bump out of the bump cavity. This solution solves the troublesome problem of smearing the release agent on the formwork during the construction process.

Description

technical field [0001] The invention relates to the field of concrete construction, in particular to a fair-faced concrete construction method for a beamless floor slab with a special-shaped curved surface. Background technique [0002] Beamless floor means that the floor layer does not have beams, and the slab is directly supported on the column, which is mostly used in exhibition halls, shops, warehouses and other buildings with large floor loads. The special-shaped curved surface beamless floor means that in order to improve the viewing degree of the building and improve the aesthetic feeling of the building, the shape of the floor slab is a curved surface, not a plane. [0003] The main steps of the fair-faced concrete construction method for the special-shaped surface beamless floor slab are: modeling optimization design → fine laying out → formwork installation → painting formwork release agent → installation of steel reinforcement → pouring concrete → curing and demou...
