The wall maintenance device structurally comprises a wireless thermodetector, a plurality of templates and a thin film, wherein a temperature sensor of the wireless thermodetector is arranged inside a wall; the templates are mounted at the lateral part of the wall; a spraying device is fixedly arranged at the outer edge on each template; the thin film covers the surface of the wall; each spraying device comprises a PVC (Poly Vinyl Chloride) pipe; a plurality of spraying holes are formed on each PVC pipe; a plurality of card supports are arranged on the templates; the PVC pipes are arranged inside the card supports in a penetrating manner; a plurality of the spraying holes are located at the same straight line; and water columns sprayed by the spraying holes and the templates form an angle of 45 degrees. The wall maintenance device provided by the utility model has the advantages of simple structure and convenience in operation, can be used for realizing positive protection effect on early-period temperature cracks generated on the wall by controlling an internal temperature of concrete through spraying of the concrete and covering the thin film on the surface, and simultaneously improving the construction quality of the wall.
Description
Technical field
The utility model relates to a kind of body of wall curing means based on automatic temperature measurement, and purpose is to reduce the early stage heat of hydration thermal stresses of body of wall by the body of wall curing means that holds water, and reduces the cracking of body of wall.
Background technology
It is serious to occupy at present on a lot of building sites the concrete exterior wall thermal cracking.In conjunction with shown in Figure 1, cause the reason of concrete exterior wall cracking to be: 1, concrete wall is in early days because the release of hydration heat of cement, can cause temperature to rise and cause volume expansion, after the hydration heat of cement rate of release slows down, because can causing temperature to descend, the surface of wall heat radiation causes the concrete wall volume contraction; 2, the expansion of concrete wall with shrink the constraint will be subjected to member on every side such as base plate or basis, can not freely take place, thereby in concrete wall, produce thermal stresses, when thermal stresses during greater than concrete tensile strength, namely can produce the temperature shrinkage crack.Reduce the measure of temperature shrinkage crack: the one, reduce the highest aquation temperature rise in the concrete wall as far as possible, the 2nd, the rate of temperature fall of reduction body of wall, the purpose of this two aspect can reach by correct body of wall maintenance process.But the maintenance process for body of wall only is artificial random watering maintenance on the building site at present, this maintenance process can not effectively reduce body of wall because the thermogenetic temperature peak value of aquation, can not effectively delay the cooling rate of body of wall, though therefore carried out maintenance, maintenance early stage thermal cracking occurs to the control body of wall and does not play a positive role.
Summary of the invention
For overcoming the existing in prior technology defective, now provide a kind of structure of utilizing the wireless automatic temperature measurement instrument to cooperate automatic spray facility and cover film to control heat of hydration thermal history in the concrete wall, thereby reduce the method for body of wall thermal cracking, this framework comprises:
One wireless thermodetector, the temperature pick up of described wireless thermodetector are located in the described body of wall;
The plural number template, described template is installed on the sidepiece of described body of wall, and outer edge is installed with a spray equipment on the described template;
One film, described film is covered in described surface of wall.
Described spray equipment comprises a pvc pipe, offers plural spray apertures on the described pvc pipe, and described template is provided with plural Kato, and described pvc pipe is arranged in the described Kato.
Described plural spray apertures is located along the same line, and the water column of described spray apertures ejection becomes miter angle with template.
The utility model makes its beneficial effect that has be owing to adopt above technical scheme:
The body of wall curing means that reduces thermal stresses based on automatic temperature measurement of the present utility model; simple in structure, easy to operate; can realize by concrete spray and surface coverage film being controlled the temperature of inside concrete; its inner hydration temperature amplitude of variation is reduced; effectively delay the cooling rate of body of wall; early stage thermal cracking is appearred in the control body of wall played positive protective effect, also improved the construction quality of body of wall simultaneously.

The specific embodiment
For the benefit of to the understanding of structure of the present utility model, describe below in conjunction with drawings and Examples.
In conjunction with Fig. 2, shown in Figure 3, the utility model proposes the maintenance process of a kind of rational and effective body of wall, can effectively reduce body of wall heat of hydration thermal stresses, reduce the cracking of body of wall, it comprises:
One wireless thermodetector (not shown), the temperature pick up of described wireless thermodetector are located in the body of wall (reinforcing cage to be built) 1;
One film 4, film 4 is covered in the surface of body of wall 1.
At first debug wireless thermodetector in use, wireless thermodetector is connected with compunlcation, both are remained within 500 meters at distance, the temperature pick up that then will debug good wireless thermodetector before concrete wall 1 is built is installed in differing heights and the different-thickness place that waits to build reinforcing cage inside, measure the temperature of inside concrete by temperature pick up, waiting that building the concrete outside installs template 2, two Katos 21 are installed in template 2 top outer edge both sides again, in Kato 21, plug pvc pipe 3, adjust the angle of spray apertures 31 and template 2, make 2 one-tenth miter angles of water column and template of ejection, adopt the water mode of sending of multiple spot to guarantee that each spray apertures 31 all has the water column ejection.
Concreting then, further combined with shown in Figure 5, after treating that concreting finishes, early stage because the release of hydration heat of cement at concrete wall 1, in the process that occurrence temperature rises, template 2 outsides are carried out the spray of water, reduce the aquation temperature rise of body of wall 1 inside, and gather body of wall internal temperature delta data by wireless thermodetector, the temperature acquisition cycle be 3 minutes once, carried out observation and the analysis of data by the special messenger, rise slowly and approach and stop spray when reaching peak value when observe body of wall 1 internal temperature by computer, and at body of wall 1 outer side covers film 4, body of wall 1 is incubated to delay the rate of temperature fall of body of wall 1, inner hydration temperature amplitude of variation is reduced, as shown in Figure 6, when the temperature value of measuring until wireless thermodetector reaches and stablizes, again template 2 is removed, just be made into surface aesthetic, the body of wall 5 that intensity is high.
Body of wall maintenance process of the present utility model; simple in structure, easy to operate; by concrete spray and surface coverage film 4 being controlled the temperature of inside concrete; its inner hydration temperature amplitude of variation is reduced; effectively delay the cooling rate of body of wall; early stage thermal cracking is appearred in the control body of wall played positive protective effect, also improved the construction quality of body of wall simultaneously.
