The present invention relates to a molding apparatus for curing a manhole or branch pipe through heating, and more particularly, a heating wire for directly curing in a state in which cement concrete is poured into a mold to form a manhole or branch pipe. It relates to a curing apparatus for curing.

In general, it is well known that the manhole or branch pipe is formed through a curing process for a certain time after the cement concrete is poured into the mold.

In detail, first, cement concrete is poured into a molding mold in a state in which a molding mold for forming a manhole or branch pipe (hereinafter, referred to as a manhole) is provided. Curing takes place under a certain temperature. Subsequently, after a certain period of time, the mold is removed from the curing chamber to separate the mold and the manhole, and the manhole is dried and cured at room temperature.

At this time, since the molding of the manhole is made at the same time a large number at the same time, the curing room necessary for curing also needs a large scale, and the problem that a large amount of energy is consumed even when maintaining a large curing chamber at a constant temperature for a certain time. have.

In addition, each of these steps is performed because the process of pouring cement concrete to the mold to mold the manhole, curing it, and separating the cured manhole from the mold are performed by different procedures in different places. The inconvenience of having to move the mold every time the process occurs.

In addition, the uncomfortable curing process described above is pointed out as a major cause of economical degradation and product quality deterioration because of the loss of manpower and loss of work efficiency, and urgent improvement is required.

The present invention has been devised to solve the problems and shortcomings of the prior art, and its main purpose is to cure the heat using a heating wire that enables direct curing in the state where the cement concrete is poured into the mold to form a manhole or branch pipe. It is an object to provide a molding apparatus for.

Another object of the technology according to the present invention is to provide a curing apparatus using a heating wire that can be cured directly in the open air even in winter, and can be used in the field.

The present invention configured to achieve the above object is as follows. That is, the curing apparatus using the heating wire of the present invention is a molding apparatus having an inner and outer molding frame for forming a manhole or branch pipe, so that a constant temperature can be generated while the heating wire is wound along the inner surface of the inner mold. An inner heating part formed; And an operation unit configured to turn on / off power supply to the inner heat generating unit and control the heat generation time and temperature.

In the above-described configuration, the outer heating unit is further configured on the outer surface of the outer mold, but the outer heating unit may be formed to be controlled through a connection with the operation unit.

In addition, when molding is formed through mutual coupling in a state in which the outer mold is divided into pieces, it may be configured to be connected through a mutual connector in a state in which an individual outer heating portion is configured on each of the partitioned outer surfaces.

Hereinafter, a curing apparatus for curing using a heating wire according to a preferred embodiment of the present invention will be described in detail.

1 is an exploded view showing a curing apparatus using a heating wire applied to the present invention, Figure 2 is a longitudinal sectional view showing a curing apparatus using a heating wire applied to the present invention, Figure 3 is a curing using the heating wire applied to the present invention Figure 4 is a cross-sectional view showing a molding apparatus for, Figure 4 is a state diagram used in the curing apparatus using the heating wire to which the present invention is applied.

The curing apparatus using the heating wire according to the present invention is largely installed on the inner and outer surfaces of the inner mold 10 or the outer mold 20a, 20b, 20c, 20d as shown in Figures 1 to 3 It consists of the heat generating part 100 or the external heat generating parts 200a, 200b, 200c, 200d, and the operation part 120 for operating these.

Thus, the inner heating portion 100 is formed so as to generate a constant temperature in a state in which the heating wire is wound along the inner surface of the inner mold 10. At this time, it is preferable that the inner heat generating part 100 is a planar heating element, and a heating wire is covered by an insulator.

Therefore, when power is supplied to the inner heat generating part 100, heat generated from the hot wire forms a structure for curing cement concrete poured through the insulator and the inner mold 10.

The operation unit 120 is formed to turn on / off power supply to the inner heat generating unit 100 and control the heat generation time and temperature. That is, the operation unit 120 is configured to supply and block the commercial power to the inner heat generating unit 100 in a state where commercial power is supplied from the outside, and to adjust the commercial power supplied. Thus, the operation unit 120 may be provided with a typical on / off switch, temperature control button, time control button and display window.

On the other hand, the outer surface of the outer forming mold (20a, 20b, 20c, 20d) further comprises an outer heating portion (200a, 200b, 200c, 200d) by heating the poured cement concrete at the same time inside and outside at a uniform temperature and time More smooth curing can be achieved. At this time, it is preferable that the outer heating portion (200a, 200b, 200c, 200d) is also formed in the form of a planar heating element, the outer molding frame (20a, 20b, 20c, 20d) is usually internally molded in a state divided into two or more Since it is formed to cover the mold 10, it is made of a configuration for connecting through the mutual connector 220 in the state installed in each of the outer molds 20a, 20b, 20c, 20d each partitioned. In the present invention, it is shown that the outer mold 200a, 200b, 200c, 200d divided into four.

The outer heating parts 200a, 200b, 200c, and 200d configured on the outer surface of the outer mold 20a, 20b, 20c, and 20d described above together with the inner heating part 100 through connection with the operation unit 120 described above. It is desirable to form to be controlled.

According to the curing apparatus using the heating wire of the present invention as described above, first assembled in a state that covers the outer mold 20a, 20b, 20c, 20d on the outer side of the inner mold 10, and then the inside Pour cement concrete into the plant.

Subsequently, the inner heating part 100 and the outer heating part 200a, 200b, 200c, 200d of the inner mold 10 and the outer mold 20a, 20b, 20c, and 20d in which cement concrete is poured are connected to the operation unit. The manhole is cured by setting temperature and time while supplying power in one state. Of course, the outer heat generating portion (200a, 200b, 200c, 200d) is connected to the operation unit 120 in a state in which each connector 220 is connected.

Therefore, according to the configuration and use as described above, when the manhole is molded, the curing process is performed directly without moving outdoors (even in winter) through the inner heating part 100 or the outer heating parts 200a, 200b, 200c, and 200d. As a result, there is no need to save manpower or equipment and prepare a separate curing room, which can greatly improve work efficiency, productivity and economy.

The present invention is not limited to the above-described embodiments and can be carried out in various modifications within the range allowed by the technical idea of the present invention.

According to the curing apparatus using the heating wire of the present invention as described above, there is no need to provide a separate curing room for curing the manhole or branch pipe, thereby eliminating the inconvenience of moving the molding apparatus according to each curing process. It is effective in improving efficiency and greatly improving productivity and economic efficiency.

In addition, according to the present invention, the manhole can be cured outdoors even in winter, and the manhole can be directly cured in the field, thus improving productivity and making work more convenient.
