Description
Technical Field
The invention relates to the field of auxiliary equipment related to concrete construction, in particular to a moisturizing and heat-insulating device for concrete winter maintenance.
Background
Concrete curing is the longest time consuming in the whole concrete construction project and is the construction operation which has the greatest influence on the concrete quality. The gradual hardening and strength increase of concrete are the result of cement hydration, and certain temperature and humidity conditions are required for cement hydration, so that certain humidity and temperature conditions are required for concrete curing artificially, so that the hardening and strength increase of the as-cast concrete can be normal or accelerated. In order to ensure the strength of concrete and prevent the concrete from generating cracks due to surface drying, watering curing is usually required to reach necessary humidity, and if the watering curing of the concrete is neglected, the strength of the concrete is reduced on one hand, and on the other hand, the concrete is not ready to supplement water in the hardening process, so that a large amount of water is lacked, and cracks are generated. However, concrete water curing is conditional, and if the temperature is lower than 4 ℃, the concrete cannot be cured by watering, because the moisture is slowly evaporated at low temperature, even the moisture is converted into solid and is not easy to evaporate to enter the concrete.
Aiming at the winter maintenance of concrete, heating and heat preservation are carried out on the basis of watering maintenance, so that the initially-solidified concrete is prevented from being frozen, and the maintenance effect that the maintenance cannot be achieved due to watering and freezing is avoided.

Although most of the contact surface of the heat-preservation curing blanket and the concrete is isolated from the outside in the long-time curing process, the through pipe part is always kept in an open state and communicated with the outside, moisture evaporated from the water storage sponge is easily diffused into the environment through the through pipe in winter when the external environment is dry and cold, on one hand, a large amount of water and heat resources are discharged into the environment to cause waste, and the heat-preservation curing blanket needs to be repeatedly watered and continuously electrified and heated in a concrete curing period of dozens of days; on the other hand, the evaporated moisture is easy to diffuse into the environment through the through pipe, so that the humidity of the concrete surface layer cannot be guaranteed, and the optimal curing effect cannot be achieved.

Detailed Description
As shown in fig. 1 or 5, the main structure of the moisturizing and insulating device for concrete winter maintenance of the present invention is an insulating pad 5, a heating pad 16, a composite functional water storage layer 3 and an isolation layer 1, which are sequentially distributed from top to bottom. The inner disk of the heating pad 16 is provided with a heating resistance wire, and the temperature is raised and maintained by using heat generated after electrification. The heat insulation pad 5 is plastic-sealed and heat-preservation cotton so as to realize the heat insulation function, and avoid the waste of heat energy generated by the heating pad 16 and the loss of water in the water storage layer 3 with the composite function. The isolation layer 1 is made of a multi-mesh geotextile material, so that the composite function water storage layer 3 is separated from the concrete surface at intervals, and the composite function water storage layer 3 is protected. The composite functional water storage layer 3 consists of water-absorbing expansion rubber 302 and water-absorbing non-expansion sponge 301, wherein the water-absorbing non-expansion sponge 301 is applied by the conventional sponge water-absorbing and water-storing means in the prior art, and water is absorbed and stored through pores distributed throughout the inner part of the sponge; the water-absorbing expansion rubber 302 is commonly used for sealing a gap to achieve the sealing effect of directly sealing a connecting pipeline through self water-absorbing expansion in the prior art, the effect of the water-absorbing expansion rubber 302 adopted in the invention is different from that of the conventional technology, on one hand, the water-absorbing expansion rubber 302 is similar to the water-absorbing non-expansion sponge 301, the water-absorbing storage effect of a water body is realized through the self water-absorbing characteristic of the water-absorbing expansion rubber 302, on the other hand, the water-heat isolation effect and the watering indication effect are indirectly and synchronously realized by utilizing the characteristic of water absorption and volume expansion, and the method is specific:
water heat insulation effect
The isolation layer 1 is provided with a vertical pipe 4 with two closed ends, the lower end of the vertical pipe 4 is rigidly connected with the isolation layer 1, and the upper end of the vertical pipe 4 sequentially passes through the through holes arranged on the composite function water storage layer 3, the heating pad 16 and the heat insulation pad 5 and then is connected with the plug 8. A plurality of water inlets 9 are arranged on the peripheral wall of the vertical pipe 4 below the plug 8 at intervals, the upper part of the perforation arranged on the heat insulation pad 5 is V-shaped and forms a diversion inclined plane 6, and water body poured on the heat insulation pad 5 can flow into the upper part of the perforation on the heat insulation pad 5 under the diversion effect of the diversion inclined plane 6 and enters the inner cavity of the vertical pipe 4 through the water inlets 9. A plurality of water injection ports 2 are arranged at the lower part of the vertical pipe 4 and at intervals corresponding to the position sides of the composite function water storage layer 3, the water in the vertical pipe 4 automatically flows into the composite function water storage layer 3 under the action of gravity, and the whole composite function water storage layer 3 is filled with the water through the capillary adsorption effect generated by small gaps in the composite function water storage layer 3.
The lower part of the plug 8 is provided with a plugging inclined plane 7 matched with the diversion inclined plane 6. When the water-swelling rubber 302 in the complex-function water storage layer 3 absorbs water, the volume thereof expands synchronously, and the bottom of the present invention is attached to the concrete surface layer, so the heating pad 16 and the heat insulation pad 5 on the water-swelling rubber 302 can be pushed to rise synchronously by the expansion of the water-swelling rubber 302 until the diversion inclined plane 6 shown in fig. 3 abuts against the blocking inclined plane 7, i.e. the upper part of the perforation in the heat insulation pad 5 is blocked by the plug 8, so that the heat-preserving and moisture-preserving interface between the complex-function water storage layer 3 and the concrete surface layer is sealed from the external environment, thereby avoiding the waste of water heat and maintaining the temperature and humidity in the gap.
Watering indication effect
As shown in FIG. 2, the stopper 8 of the present invention comprises a rigid inner core 802 slidably disposed on the top end 11 of the vertical tube 4 and a flexible sheath 801 covering the rigid inner core 802. The flexible sleeve 801 is made of rubber materials, the plugging inclined plane 7 is arranged at the lower part of the flexible sleeve 801 and can deform under pressure to adapt to the extrusion acting force of the heat insulation pad 5, and connection damage between the plug 8 and the plug 11 or connection damage between the lower end of the standpipe 4 and the isolation layer 1 caused by continuous expansion of the water absorption expansion rubber 302 is avoided. The inner edge of the rigid inner core 802 is fixedly provided with a press ring 13, the top 11 is provided with a ring groove 12 along the circumferential direction for the press ring 13 to be inserted, and the height of the ring groove 12 is larger than the thickness of the press ring 13, so that the rigid inner core 802 can freely slide up and down along the top 11 and the sliding is formed to correspond to the width of the ring groove 12. An LED flashing lamp head is arranged on the upper edge of the top 11 as an indicator lamp 10, a battery for supplying power to the indicator lamp 10 is arranged in a battery compartment (not shown) arranged inside the top 11, and a switch for turning on and off the indicator lamp 10 to flash or be normally closed is arranged on a power supply circuit between the battery and the indicator lamp 10. The water storage state of the composite function water storage layer 3 is shown through the flashing or normally closed state of the indicator light 10, so that an operator can judge whether watering is needed.
The switch in the invention is an elastic switch 14 which is arranged on the groove wall at the lower side of the ring groove 12, and is communicated with the power supply circuit of the indicator light 10 under the pressing state, and is disconnected with the power supply circuit of the indicator light 10 under the non-pressing state. As shown in fig. 1 and 2, when the water-swellable rubber 302 in the composite-function water storage layer 3 is not water-swellable, the plugs 8 are spaced at the upper edge of the heat insulation pad 5, and at this time, the plugs 8 lack support, so that the pressing ring 13 is located on the lower side wall of the annular groove 12 under the action of self gravity and presses the elastic switch 14, and the elastic switch 14 connects the indicator light 10 and the battery and makes the indicator light 10 flash continuously to prompt watering. In the state shown in fig. 3 and 4, when the water-absorbing expansion rubber 302 expands to make the heat insulation pad 5 rise and push the plug 8 to move upwards from bottom to top, the diversion inclined plane 6 on the heat insulation pad 5 first contacts with the plugging inclined plane 7, and then pushes the plug 8 to move upwards integrally to separate the press ring 13 from the elastic switch 14, at this time, the power supply circuit of the indicator light 10 is disconnected and kept in a normally closed state, and an operator is prompted to finish water absorption of the composite-function water storage layer 3 without continuously watering. Therefore, when the operator sees the indicator light 10 to light, the operator performs the watering operation, and when the indicator light 10 is seen to be extinguished, the watering operation is stopped, and the watering indicating effect is simple and clear, and is convenient to implement.
Further, after the pressing ring 13 moves upwards to the upper side groove wall of the ring groove 12 shown in fig. 4 along with the continuous upward movement of the heat insulation pad 5, the rigid inner core 802 cannot move upwards continuously, but the flexible sleeve 801 and the heat insulation pad 5 can be adapted to the further small-amplitude expansion of the water-absorbing expansion rubber 302 through mutual deformation, and the diversion inclined surface 6 and the blocking inclined surface 7 are further attached through the deformation of the flexible sleeve 801 and the heat insulation pad 5, so that the hydrothermal sealing effect is ensured.
The structure and the corresponding technical effects of the multifunctional water storage layer 3 of the present invention are described in detail by two embodiments as follows:
example 1
As shown in fig. 1, the complex function water storage layer 3 in this embodiment comprises a layer of water-absorbing expansion rubber 302 under the heating mat 16 and a layer of water-absorbing non-expansion sponge 301 under the water-absorbing expansion rubber 302 and above the insulation layer 1. Under the condition of ensuring that the total thickness of the embodiment is smaller so as to be convenient for laying, storing and transporting, the thickness of the water-absorbing expansion rubber 302 in the non-water-absorbing state is about one third of the thickness of a water-absorbing non-expansion picture. As shown in fig. 3, after the water-absorbing expanded rubber 302 and the water-absorbing non-expanded sponge 301 absorb water, since the water-absorbing expanded rubber 302 is located above the water-absorbing non-expanded sponge 301, the water in the water-absorbing non-expanded sponge 301 located below enters the concrete first when heated by the heating mat 16 and the top of the composite functional water storage layer 3 is sealed by the heat insulating mat 5 and the plug 8, and the water in the water-absorbing expanded sponge 302 begins to run off and rapidly passes through the water-absorbing non-expanded sponge 301 to enter the concrete after the water in the water-absorbing expanded sponge 301 is dehydrated and dried. On one hand, under the condition that the water-absorbing non-expanded sponge 301 is thick and the water storage capacity is large, the embodiment can fully utilize the water body in the water-absorbing non-expanded sponge 301 to realize longer watering interval; on the other hand, through the sequence of dehydration, in the process of dehydrating and moisturizing the water-absorbing non-expanded sponge 301, the water-absorbing expanded rubber 302 can maintain the expanded state for a long time and maintain the plugging state of the plug 8 for a long time, so that the embodiment has a longer watering interval and saves manpower.
In addition, since the water-absorbent swelling rubber 302 stores water by generating a stronger binding force through the binding of its own hydrophilic group, the water loss rate thereof is slower than that of the water-absorbent non-swelling sponge 301. If the water is supplied to the concrete below only through the water-loss expansion rubber after the water-absorption non-expansion sponge 301 is dehydrated and dried, the problem that the humidity of the concrete surface maintenance surface does not reach the standard is easily caused. The watering indicating system in the invention can just avoid the problem, and specifically comprises the following components:
after the water-absorbing non-expanded sponge 301 loses water and is dried, the water-absorbing expanded rubber 302 begins to lose water and shrink, and the water-absorbing expanded rubber 302 does not need to lose water until the water-absorbing expanded rubber is completely dried and shrinks to the state shown in fig. 1, and then the indicator light 10 is started to give a watering indication, but a watering indication signal is generated in advance when the water-absorbing expanded rubber 302 primarily loses water and shrinks. As shown in fig. 4, since the pressing ring 13 is located on the upper side wall of the annular groove 12 in the water-absorbing expansion state, the water-absorbing expansion rubber 302 only needs to be contracted to a height corresponding to about the width of one annular groove 12, that is, the heat insulation pad 5 is lowered to a height corresponding to about the width of one annular groove 12, so that the plug 8 and the pressing ring 13 thereon are lowered to the lower side wall of the annular groove 12 under the action of self-gravity to press the elastic switch 14, and the indicator light 10 is turned on to send a watering signal when the water-absorbing expansion rubber 302 is in a slightly water-loss state. The worker can water after seeing the watering indication signal, so that the water-absorbing non-expanded sponge 301 absorbs water rapidly to maintain the necessary humidity of the concrete surface maintenance gap, and the problem that the watering indication is sent after the water-absorbing expanded rubber 302 is completely dehydrated and dried, and the humidity of the concrete surface maintenance interface is low due to the low dehydration speed of the water-absorbing expanded rubber 302 is solved.
Example 2
As shown in fig. 5, the composite functional water storage layer 3 in this embodiment is composed of a layer of water-swellable rubber 302 located in the middle and two layers of water-absorbent non-swellable sponges 301 located on the upper and lower sides of the water-swellable rubber 302. In this embodiment, the two water-absorbing non-swelling sponges 301 have the same thickness and the same total thickness as the single-layer water-absorbing non-swelling sponge 301 in embodiment 1, and in the non-water-absorbing state shown in fig. 5, the thickness of the water-absorbing rubber is the same as that in embodiment 1, so that the thickness in this embodiment is the same as that in embodiment 1 to ensure the convenience of laying, storing and transporting. The water-swellable rubber 302 in this embodiment is slightly different from that in embodiment 1, and the water-swellable rubber 302 in this embodiment is provided with a plurality of connection holes 15 distributed along its thickness.
Through the above structure, in the maintenance state that the composite-function water storage layer 3 is heated by the heating pad 16 after absorbing water in the embodiment, the water in the lower water-absorbing non-expansion sponge 301 runs off first to enter the concrete. The water in the water-absorbing expanded rubber 302 and the water in the upper water-absorbing non-expanded sponge 301 start to run off synchronously after the water-absorbing non-expanded sponge 301 at the lower part is dehydrated and dried, because of the connecting hole 15, and rapidly pass through the water-absorbing non-expanded sponge 301 at the lower part to enter the concrete.
According to the above characteristics, in this embodiment, after the water-absorbing non-swelling sponge 301 located below is dehydrated and dried, and before the water-absorbing swelling rubber 302 is dehydrated to the height corresponding to the width of one ring groove 12 to trigger the indicator light 10 to light up, the water is discharged through the water-absorbing non-swelling sponge 301 and the water-absorbing swelling rubber 302 above together to maintain the humidity of the concrete curing interface, and the water is still discharged through the water-absorbing non-swelling sponge 301 and the water-absorbing swelling rubber 302 above together to maintain the humidity of the concrete curing interface within a period of time after the indicator light 10 lights up. Therefore, watering is not needed to be carried out in the first time after the indicator light 10 is turned on the basis of ensuring the standard maintenance humidity. This characteristic of this embodiment is particularly useful for pilot lamp 10 and lights when nobody nurses at night, and constructor still can be bright in daytime next day and see pilot lamp 10 and instruct the water in the replenishment complex function water storage layer 3 that waters again to give this embodiment certain fault-tolerance in concrete maintenance construction, alleviateed the maintenance degree of difficulty that this embodiment carries out concrete moisturizing heat preservation by a wide margin.
