A high-efficiency energy-saving concrete slab

Abstract

The invention belongs to the technical field of construction, specifically a high-efficiency and energy-saving concrete slab; it includes a partition and an elastic board; the elastic board is fixed on the two side walls of the partition; a cavity is opened inside the partition, The top of the partition is provided with a metal cover; the No. 1 cavity is provided with pearl cotton; the concrete floor is divided into blocks through the cooperation of the partition and the elastic board; the concrete slab is separated by the partition before the concrete slab is poured It can be formed into blocks, which avoids processing after the concrete slab is poured and formed, improves the work efficiency of the staff, reduces the work difficulty and processing cost of the staff, and saves a lot of manpower and material resources; and is fixed on the two side walls of the partition The elastic plate can make the partition fully adapt to the expansion of the concrete floor on both sides of the partition, prevent a large amount of heat from spreading in the concrete floor, reduce the deformation range of the concrete floor, and reduce the impact of high temperature on the concrete floor.

Description

technical field [0001] The invention belongs to the technical field of buildings, in particular to a high-efficiency and energy-saving concrete slab. Background technique [0002] In areas with high temperature all year round, due to the high temperature, the local concrete slab floor is heated and expanded, which causes a large internal stress inside the concrete slab floor, which causes the arch of the concrete slab floor, thereby destroying the concrete slab floor. In order to avoid For this defect, the concrete slab will set expansion joints and shrinkage joints during construction. At present, the setting of expansion joints is to complete the complete cutting from top to bottom on the concrete pavement through the pavement slitting machine, and divide the whole concrete slab into many small concrete slabs; One is that the cutting depth of the concrete slab is relatively deep, which consumes a lot of manpower and material resources. The other is that the diameter of th...

At present, the setting of expansion joints is to complete the complete cutting from top to bottom on the concrete pavement through the pavement slitting machine, and divide the whole concrete slab into many small concrete slabs; One is that the cutting depth of the concrete slab is relatively deep, which consumes a lot of manpower and material resources. The other is that the diameter of the cutting wheel of the road cutting machine is small, so it is difficult to cut to the bottom of the concrete slab, which affects the Construction Quality
