Problems solved by technology

[0006] Moreover, most of the current maintenance of the floor in construction only stays in the simple covering of the surface insulation layer and artificial random watering maintenance. When this maintenance method starts watering maintenance, when it needs to be covered with insulation layer, and how to determine the amount of watering, all depends on the maintenance method. There is no clear method, and the intensity of manual watering is high, which requires a lot of manpower
In addition, even if there is manual watering, the workers will rest at night, and there will be no one to take care of them at night

Embodiment Construction

[0027] In order to facilitate the understanding of the structure of the present invention, the following description will be made in conjunction with the accompanying drawings and embodiments.

[0028] figure 1 It is a schematic diagram of the measurement positions of concrete floor beams and floor slabs in the concrete floor structure maintenance method, figure 2 It is a flow chart of the concrete floor structure maintenance method.

[0029] combine figure 1 and figure 2 As shown, in the first embodiment, the present invention provides a method for maintaining the structure of a concrete floor, comprising the following steps:

[0030] pouring a concrete floor comprising floor slabs and floor beams fixedly connected beneath said floor slabs,

[0031] S1. In this embodiment, a measurement point is set on the floor slab, marked as: the first measurement point 1, and the first measurement point 1 is set at any point on the cross-section of the middle point of the height of ...

Abstract

The invention provides a structure maintenance method and system of a concrete floor. The method includes the following steps that firstly, a first temperature sensor located on a first measurement point for monitoring the internal temperature Tboard is arranged on a floorboard; a second temperature sensor, a third temperature sensor and a fourth temperature sensor located on a second measurement point, a third measurement point and a fourth measurement point respectively are arranged on different height layers of a floor beam and used for measuring the average temperature Tbeam of the floor beam; secondly, the temperature difference deltaT between the Tboard and the Tbeam is calculated, wherein deltaT=Tbeam-Tboard; thirdly, when the deltaT is larger than a preset value, a heat preserving layer is additionally arranged for the floor structure; fourthly, when the temperature difference deltaT reaches the largest value and starts to decrease, water is sprinkled onto the floor. The method and system have the advantages that due to the measurement of additionally arranging the heat preserving layer, the temperature difference between the floorboard and the floor beam is reduced, the surface of the concrete floor structure is kept moist by sprinkling water, and finally the floor is efficiently prevented from fracturing in real time.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a maintenance method and system for a concrete floor structure. Background technique [0002] With the development of society and economy, the pace of urbanization is getting faster and faster, concrete floor pouring has become everywhere, but at present, cracks on the surface of concrete floors on many construction sites are becoming more and more serious. Common causes of cracking in concrete floors are: [0003] The thickness of the floor slab is relatively thin, and the thickness is generally 1 / 4 to 1 / 5 of the floor beam. Therefore, the hydration heat of the floor slab in a bay is faster than that of the floor beam around the same wall. When the temperature of the floor slab no longer rises , the temperature of the floor beams is still rising, causing the volume expansion of the floor beams, which will eventually cause the floor beams to pull the floor ...
