Embodiment Construction
[0014] Fix the steel mesh 2 and the steel mesh 14 on the outer side of the bound steel frame 1 with the fixing part 3 composed of the clip 8 and the fixing screw 5, and use the screw rod 12, the nut 10, the nut 11 and the angle steel 7 and the angle steel 9. The fixing part 4 connects the steel mesh 2 and the steel mesh 14 on both sides, and pours self-compacting and vibration-free concrete into the steel mesh 2 and the steel mesh 14. After the concrete reaches a certain strength, the angle steel 7 and the angle steel 9 on both sides are removed.

A concrete construction technology for without detaching formworks includes such steps as using the fixing parts to fix the meshes to external sides of bar skeleton, using the fixing parts of connectsaid meshes, pouring the self-compacting non-vibration concrete in the space between said meshes, solidifying the concrete, and detaching the angle steel. Its advantages include no need of vibration and detaching formworks, no noise pollution, low cost and high quality.
Description
technical field [0001] The invention belongs to the field of construction engineering. Background technique [0002] The traditional concrete construction process is generally as follows: bind the steel skeleton 1 according to the design requirements; support the concrete formwork according to the size required by the design; pour concrete into the concrete formwork and vibrate the concrete with a vibrator; remove the formwork after the concrete reaches a certain strength . [0003] The wooden formwork will be eliminated after being used several times, and the cost of the steel formwork is relatively high; the vibration and noise of the traditional concrete construction is large, disturbing the residents, and causing environmental pollution; It is not easy to observe, and the "container" composed of the formwork is in a closed or semi-closed form, so it is difficult to get rid of air bubbles or air, and it is difficult to guarantee the construction quality.
