Problems solved by technology

[0004] (1) Damage to floor heating coils caused by material stacking: Since traditional floor heating concrete backfilling is mostly carried out in households, and the amount of concrete is relatively small, there is a very common phenomenon of on-site mixing of concrete. Due to the limited space on site, raw materials The storage space is limited, and it is often directly pressed on the floor heating coil that has been laid, which will cause deformation of the floor heating coil under pressure, irreversible structural damage or even cracking, making the floor heating coil at a high level before construction begins. In danger, after the construction is completed, there is a great probability that water leakage will occur before the service life is reached
[0005] (2) The concrete mix ratio cannot be strictly controlled: the backfill concrete that is directly mixed on site usually does not have strict measuring instruments and measurement control management. A rough judgment is made based on the experience of the construction personnel. For the convenience of construction, the mixing wa

Embodiment 1

[0040] (1) Grading of raw materials: Separately screen the coarse aggregate and fine aggregate whose quality and type meet the standard requirements to ensure the particle size requirements.

[0041] In step (1), the maximum particle size of the coarse aggregate is 15 mm, the maximum particle size of the fine aggregate is 5 mm, and the fine aggregate is fine sand.

[0042] The coarse aggregate in step (1) is pebbles with low density porosity and high density. Specifically, the fine aggregate is natural fine sand.

[0043](2) Homogenization of composite materials: Put coarse aggregate, fine aggregate, cementitious material and dry powder additives into the mixer for dry mixing in sequence, and mix them evenly to form dry mixed concrete mixture.

[0044] In step (2), the volume ratio of coarse aggregate, fine aggregate and cementitious material in the dry-mixed concrete mixture raw material is 3:3:1. The mass ratio of gelling material, rubber powder and cellulose in the raw ma...

Abstract

The invention provides a method for constructing floor heating concrete back-filling layers. Compared with existing construction methods in the prior art, the method has the outstanding advantages that raw materials are classified, dry-mixed concrete is mechanically homogenized, watering is directly carried out after the dry-mixed concrete is uniformly paved, dry mixtures are easy to pave as compared with wet concrete mixtures, constructors wear soft-soled shoes, and accordingly floor heating coil pipes are hardly damaged in operation construction procedures by the aid of flat-end shovels; the completely paved dry concrete mixtures are watered by uniform watering equipment in watering procedures, the floor heating coil pipes are free of damage, and accordingly the durability can be guaranteed in follow-up use; field staffs, construction tools, the raw materials, the method and the like are reasonably and effectively planned, organized, coordinated, controlled and detected and are in excellent combination states, and accordingly the purpose of high-quality, efficient, low-consumption, balanced, safe and civilized production can be achieved.

Description

technical field [0001] The invention relates to the technical field of decoration, in particular to a construction method for a ground heating concrete backfill layer. Background technique [0002] Floor heating is the abbreviation of floor radiant heating. It uses the whole ground as a radiator, and heats the whole ground evenly through the heat medium in the radiant layer of the floor. The purpose of heating. Studies have shown that ground radiation heating is the most comfortable heating method. The indoor surface temperature is uniform, and the room temperature gradually decreases from bottom to top, which is not easy to cause dirty air convection, and the indoor air is clean. In view of the above advantages, the floor heating system has been widely used in the field of building decoration today. [0003] In the construction process of the existing floor heating concrete backfill layer, there are still many problems as follows: [0004] (1) Damage to floor heating coi...
