Description

Concrete Curing Device {An Apparatus for become hard of concrete}

The present invention relates to a concrete curing device that is capable of early curing concrete for fixing a bridge expansion joint and prevents the occurrence of cracking of the concrete. From the inside of the steam filling unit is filled with steam, and a support for supporting and fixing the outside of the steam filling unit is installed, so that the heating of a certain temperature can be filled in the concrete pouring site, the casting of concrete The temperature difference between the heat generated inside the city and the temperature difference between the outside air on the concrete surface and the evaporated moisture can be compensated by the heating steam to prevent cracking of the concrete, and thus, damage to the expansion joint device. It can prevent and shorten the curing time of the concrete, it is possible to proceed to the next step quickly It relates to rokhan concrete curing device.

In general, the concrete to be cast when fixing the expansion joint of the bridge, in the state in which the concrete is placed on the expansion joint, it is cured naturally at room temperature without a separate curing method during curing.

When concrete is cured after pouring concrete into the expansion joint as described above, the difference between the heat generated inside the concrete (called "hydration heat") and the outside air on the concrete surface, and the concrete As the moisture in the net evaporates to the outside, a lot of cracks are generated, and thus, the expansion joint also has a disadvantage of being initially broken.

In particular, when the concrete is naturally cured as described above, the curing time takes a long time by the external temperature, thereby causing a delay of the next process, resulting in a lot of traffic.

The present invention has been made in order to improve the conventional problems as described above, the purpose is, when the concrete pouring of the expansion joint device, the steam filling unit is installed inside the steam filling device from the steam curing device outside the concrete placing site And, a support for supporting and fixing the outside of the steam filling portion is installed, so that the heating steam of a predetermined temperature is filled in the concrete placing portion, the heat generated inside the concrete during casting and the outside air of the concrete surface ( The temperature difference between the external temperature and the evaporated moisture is compensated by the heating steam to prevent the cracking of the concrete, and thus, the breakage of the expansion joint is prevented, and the curing time of the concrete is shortened. Concrete to speed up the next process and minimize traffic jams It is a to provide a production device.

As a technical means for achieving the above object, the present invention, the steam inlet hole communicated with the steam generator is formed so that the steam is filled inside the concrete placing portion, the steam outlet hole is formed on both sides, A steam filling part installed to maintain the concrete pouring part at a constant temperature;

A cushioning material installed at the periphery of the bottom of the steam filling part and installed to block outflow of steam;

By forming a structure as a plurality of bars to the outside of the steam filling, the support is installed so as to support the steam filling portion; by providing a concrete curing device, characterized in that it comprises a.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic exploded perspective view of the concrete curing device of the present invention, Figure 2 is a front sectional structural view of the steam filling unit installed in the concrete pouring portion of the concrete curing device of the present invention and Figure 3 is the steam filling of the present invention As a schematic perspective view of the coupled state of the support and the support, the concrete curing apparatus of the present invention, the steam filling portion 10 of the rectangular shape so that the steam (S) is filled inside the concrete placing portion (A) is located, A steam inlet hole 30 is formed in front of the steam filling unit 10 to communicate with the steam generator through a pipe 20.

In addition, steam discharge holes 80 are formed on both sides of the steam filling part 10, respectively, and the concrete pouring part A is installed to maintain a constant temperature, and the bottom of the steam filling part 10 is formed. At the periphery, the cushioning material 40 is installed so as to block the outflow of steam, and the weight of the cushioning material 40 is placed on the upper side of the cushioning material 40 so that the cushioning material 40 can be in close contact with the concrete placing portion A. Sieve K is installed.

Subsequently, a support 60 having a structure 50 as a plurality of bars is provided outside the steam filling part 10, and is bundled with the steam filling part 10 and the string 70 to fill the steam filling. It is made of a configuration to support the fixed portion 10.

Referring to the operation and effects of the present invention made of such a configuration as follows.

As shown in Figures 1 to 3, when explaining the curing action through the concrete curing device of the present invention, the rectangular shape of the concrete placing portion (A) of the concrete placing of the expansion joint is completed It is installed in the form of covering the steam filling part 10 of the.

At this time, the steam filling unit 10 is composed of a vinyl or cloth and heated from the steam generator (not shown) and the pipe 20 through the steam inlet hole 30 formed in the front so as to fill the steam therein. Allowed steam to enter.

On the other hand, both sides of the steam filling unit 10 allows the cold steam to be discharged through the steam discharge hole 80, the newly heated steam is introduced through the steam inlet hole 30, the concrete The pouring site A may be maintained at a predetermined temperature, for example, 40 to 100 ° C., so that heat generated during curing of the concrete and the temperature of the outside air are set to be substantially the same, and at this time, the bottom of the steam filling unit 10 ( At the periphery, the weight member K is positioned above the cushion member 40 in a state in which the cushion member 40 such as a sponge is installed, whereby the cushion member 40 is placed on the concrete. Close contact with A) prevents the outflow of heated steam.

Subsequently, in order to fix the steam filling unit 10 made of vinyl or cloth as described above, the support 60 is mounted on the outside of the steam filling unit 10 by using a structure 50 in which a plurality of bars are assembled. By installing, when the steam filling unit 10 and the straps 70 to tie with the support 60, the steam filling unit 10 is fixed to the support 10 to cure the concrete through the heated steam It is possible to prevent cracks such as concrete while reducing the time.

As described above, according to the concrete curing apparatus according to the present invention, the temperature difference between the heat generated in the interior of the concrete and the outside air on the surface of the concrete and the evaporated moisture is compensated by the heating steam It is possible not only to prevent the occurrence of cracking of concrete, but also to prevent breakage of the expansion joints, and to shorten the curing time of the concrete so that the next process can be performed quickly and the traffic jam can be minimized. It works.
