Problems solved by technology

[0003] After the foam concrete is poured, it will gradually solidify and harden due to the hydration of the cement, and the hydration requires appropriate temperature and humidity conditions. Due to the hot climate and dry air, the foam concrete will evaporate too quickly if it is not maintained in time. , forming a dehydration phenomenon, the cement particles that have formed a gel cannot be fully hydrated, cannot be converted into stable crystals, and lack sufficient cohesive force. In addition, when the concrete does not have sufficient strength, the water evaporates prematurely It will also produce large shrinkage deformation, dry shrinkage cracks, and even through the cracks
[0004] At present, the main problem in the construction of foam concrete is the waste of cost. Specifically, the covering materials are for one-time use, resulting in great waste

Embodiment 1

[0039] Such as Figure 1~4 As shown, a foam concrete curing device includes: a container 1; a geomembrane elastic roll 2 located in the container 1, which is used to provide a geomembrane 21 covering the foam concrete; a geomembrane is provided below the middle of the container 1 The open end 11 drawn from one end of 21; the positioning rod 3 is used to fix one end of the geomembrane 21 drawn from the container 1, so that the drawn geomembrane covers the surface of the foam concrete.

[0040] In the present invention, by arranging the geomembrane 21 in the container 1, the geomembrane 21 that does not participate in maintenance can be stored for secondary use. During use, the container 1 can be fixed first, and positioned by translation The rod 3 allows the geomembrane 21 to be pulled out from the container 1 to cover the surface of the foamed concrete. The water-proof property of the geomembrane 21 can prevent the moisture in the foamed concrete from volatilizing into the spa...

Embodiment 2

[0048] In the above-mentioned embodiments, the one-time water supply method is mainly used in the technical direction of increasing the humidity of the geomembrane 21 , that is, the curing method of the foamed concrete is optimized by the water taken out from the container 1 at one time.

[0049] In this embodiment, different from the first embodiment, it is intended to provide the geomembrane 21 with a continuous water supply for a required period of time in a full cycle. Specifically, such as Figure 5~7 As shown, separation structures 4 for supporting the two layers in the geomembrane 21 are arranged on the inner wall of the container 1 on both sides of the gap height direction of the opening end 11. In this embodiment, it is also necessary to reduce the opening end as much as possible. The gap height of 11, the separation structure 4 is used to separate the two layers of geomembrane 21 and support and guide the two layers, and the two layers of geomembrane 21 are respectiv...

Abstract

The invention relates to the technical field of concrete curing, in particular to a foam concrete curing device. The foam concrete curing device comprises a container, a geomembrane elastic winding and unwinding roll positioned in the container and a positioning rod, wherein the geomembrane elastic winding and unwinding roll is used for covering foam concrete; the container is equipped with an opening end for allowing one end of a geomembrane to guide out; and the positioning rod is used for fixing one end of the geomembrane guided out from the container, so that the guided-out geomembrane covers a foam concrete surface. According to the foam concrete curing device disclosed by the invention, the geomembrane is arranged in the container, so that the geomembrane which does not participate in curing can be stored; in a using process, the container is firstly fixed, so that the geomembrane is pulled out from the container for use through a way of horizontally moving the positioning rod, and the foam concrete surface is covered; the geomembrane can block water in the foam concrete from volatilization, so that strength of the foam concrete is improved while cracks of a foam concrete surface layer are reduced. Through the method, the geomembrane can be utilized for a second time, so that curing cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of concrete maintenance, in particular to a foam concrete maintenance device. Background technique [0002] Foamed concrete is a new type of microporous lightweight environmental protection material, which has the characteristics of lightness, self-support, self-tightness, adjustable bulk density, convenient construction, thermal insulation, etc., and is widely used in embankments of soft foundation road sections , Widening of embankments, frost-heaving embankments in cold areas of steep slopes, load reduction on structural roofs, backfilling of abutment abutments, backfilling of pre-buried pipelines, backfilling of voids, rapid rescue of landslides, and thermal insulation of various pipelines. [0003] After the foam concrete is poured, it will gradually solidify and harden due to the hydration of the cement, and the hydration requires appropriate temperature and humidity conditions. Due to the hot climate ...
