Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, in particular to an electric heating shed for winter concrete maintenance. Background Art

[0002] After concrete is poured, it can gradually solidify and harden mainly because of the hydration of cement, which requires appropriate temperature and humidity conditions. Therefore, in order to ensure that concrete has suitable hardening conditions and its strength continues to increase, concrete must be cured. Winter weather is cold, and if it is not properly maintained, concrete is very easy to freeze, and may have cracks, looseness, long solidification time and other quality problems.

[0003] Traditional concrete curing methods include spray curing agent method, heat storage method and greenhouse method, etc. The greenhouse method uses a heat-insulating greenhouse to harden the concrete at a suitable temperature.

[0004] Existing heat preservation sheds usually use bamboo strips or steel bars to tie them into a semicircular frame, and then lay plastic film on the frame, and insert the frame into the soil when in use. This kind of heat preservation shed is difficult to build, has poor insulation effect, and consumes a lot of energy. It also requires manual supervision and a lot of operations to control the temperature increase. In particular, the use of coal heating can easily cause carbon monoxide poisoning to operators and cause various safety problems. If the operation is improper, it will cause uneven heating and there is also a risk of concrete cracking. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the relevant technical solutions. Obviously, the described embodiments are only part of the embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1 As shown, the electric heating greenhouse for winter concrete curing disclosed in this embodiment includes a keel 1, a bottom shed 2 and a ceiling 3.

[0028] The keel 1 includes a bottom keel frame 11 and a top keel frame 12 .

[0029] like Figure 2 As shown, the bottom shed keel frame 11 includes two horizontally arranged circular steel pipes, between which a plurality of vertical steel pipes are evenly arranged along the circumferential direction. Four vertical limit columns 13 are arranged between the two circular steel pipes.

[0030] like Figure 3 As shown, the ceiling keel 12 is conical, and the bottom ends of multiple steel pipes are evenly fixed on the circumference of the top circular steel pipe of the bottom keel 11, and the top ends are placed on the upper end of the center of the circular steel pipe and welded and fixed; two circular rings 14 for strengthening the structural strength are fixed in the middle section of each ceiling keel.

[0031] like Figure 4 As shown, the bottom shed 2 is fixed to the periphery of the bottom shed keel frame 1 by a cable tie. The bottom shed 2 includes an inner waterproof layer 21, an electric heating layer 22, a heat-insulating layer 23 and an outer waterproof layer 24 arranged from the inside to the outside.

[0032] The inner waterproof layer 21 and the outer waterproof layer 24 are both made of silicone fiberglass flame retardant cloth. The silicone fiberglass flame retardant cloth has excellent waterproof and flame retardant properties, can prevent rain and snow on the outside, prevent the evaporation of water in the base water film on the inside, and can also prevent leakage.

[0033] The electric heating layer 22 is provided with a nickel-chromium alloy heating wire. The silicone nickel-chromium alloy heating wire has the characteristics of being soft, fold-resistant, high temperature resistant, corrosion-resistant, uniformly heated, safe and reliable.

[0034] The insulation layer 23 is aluminum silicate flame retardant insulation cotton. The main components of aluminum silicate flame retardant insulation cotton are aluminum silicate fiber and inorganic gelling material, which has good thermal insulation and heat insulation performance; aluminum silicate insulation cotton has low thermal conductivity, which can effectively reduce heat conduction and improve the insulation effect of the building; aluminum silicate insulation cotton has good fire resistance, and its fire resistance temperature can reach above 1400°C; aluminum silicate insulation cotton also has sound absorption performance, which can reduce noise pollution.

[0035] The inner waterproof layer 21, the electric heating layer 22, the thermal insulation layer 23 and the outer waterproof layer 24 are connected to each other by Velcro. The Velcro connection is easy to disassemble and assemble, easy to use, and the installation effect meets basic use requirements.

[0036] like Figure 5 As shown, the top of the bottom shed keel frame 11 is closed by a circular insulation layer 23; the bottom of the insulation layer is provided with an electric heating layer 22. The insulation layer and the electric heating layer are connected to the top of the limiting column 13 by Velcro. The insulation layer is fixed to the periphery of the bottom shed by Velcro.

[0037] The side wall of the bottom shed is provided with a door for entry and exit, which can be sealed. A thermometer is provided on the door to measure the temperature inside and outside the greenhouse.

[0038] The ceiling 3 is a waterproof plastic film, which is attached and fixed on the ceiling keel frame 12. The ceiling can ensure the sealing of the whole greenhouse to prevent rain; at the same time, the structure of the ceiling is simple, which can save materials.

[0039] like Figure 6 As shown, when using the greenhouse, this embodiment divides every four greenhouses into one group. Considering that the maximum power of a single electric heating greenhouse device reaches 800W, the existing storage battery cannot meet the requirement of long-term endurance, so a generator is used for power supply.

[0040] The four greenhouses are arranged in a rectangular orientation, and a generator 4 is arranged in the center of the four greenhouses. Angle iron piles 5 are arranged on both sides of the generator, and the angle iron piles are driven into the ground to pull and fix the generator. The generator is connected to the four greenhouses through power lines 6 to supply power to the electric heating layer for heating.

[0041] The generator can run at full load for up to twelve hours, so it only needs to be oiled and the temperature monitored once every twelve hours; this can meet the need for unmanned monitoring overnight.

[0042] The advantages of using this greenhouse are:

[0043] 1. Electric heating layer and thermal insulation layer are set up, and the heating effect is significantly improved compared with the existing technology.

[0044] 2. The heating layer has a simple layout, uniform heating and good controllability, which avoids the risk of cracks caused by uneven heating of the concrete.

[0045] 3. The site layout is simple, the on-site layout time is short, and the labor cost is reduced; at the same time, there is no need for special personnel to burn coal and watch, avoiding the safety risk of carbon monoxide poisoning.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although detailed descriptions are made with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
