A Concrete Ultra-flat Floor Cut-Free Construction Structure

Abstract

The invention discloses a non-slitting construction structure of a concrete super-flat terrace. The construction structure comprises a concrete terrace and a terrace foundation poured in the concreteterrace, wherein the terrace foundation comprises a partition plate network, a terrace steel bar layer, and a supporting mechanism for supporting the partition plate network and the terrace steel barlayer; the supporting mechanism comprises a plurality of supporting rings arranged in an array mode; and an auxiliary supporting frame is arranged between every two adjacent supporting rings arrangedin the same row and between every two adjacent supporting rings arranged in the same column in the supporting mechanism. According to the construction structure, the super-flat terrace is subjected tonon-slitting construction by arranging the partition plate network, the terrace steel bar layer and the supporting mechanism for supporting the partition plate network and the terrace steel bar layer; the height of main supporting frames, transition supporting frames and the auxiliary supporting frames can all be adjusted through adjustment bases so as control the elevation of the partition platenetwork; and the surface finishing operability is controlled by using the partition plate network, the uncontrollable property of concrete surface finishing is effectively reduced, and the smoothnessof the concrete surface is improved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a construction structure for super-flat concrete floors without cutting seams. Background technique [0002] With the rapid development of the economy, the demand for large workshops, electronic workshops, logistics warehouses and other buildings is increasing, and the requirements for the flatness of the ground and construction quality are becoming more and more stringent according to the functions. According to the "Quality Acceptance Specification" (GB50209-2002), the surface flatness of cement concrete is 5mm / 2m, which is far from meeting the quality requirements of building functions. At present, the control of concrete surface flatness in the industry mainly depends on the actual construction level of the construction personnel, and the controllability is low; in addition, according to the performance of concrete and the requirements of national re...

[0002] With the rapid development of the economy, the demand for large workshops, electronic workshops, logistics warehouses and other buildings is increasing, and the requirements for the flatness of the ground and construction quality are becoming more and more stringent according to the functions. According to the "Quality Acceptance Specification" (GB50209-2002), the surface flatness of cement concrete is 5mm / 2m, which is far from meeting the quality requirements of building functions.

At present, the control of concrete surface flatness in the industry mainly depends on the actual construction level of the construction personnel, and the controllability is low; in addition, according to the performance of concrete and the requirements of national regulations, it is necessary to cut induction joints on the floor to prevent and reduce the occurrence of concrete cracks , the current industry practice is to use machinery to cut the joints after the concrete solidifies. Because it is difficult to grasp the cutting time, the joints cannot be cut in time after the concrete solidifies, resulting in shrinkage stress cracks
