Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial application field> The present invention relates to a heating mixture storage box, that is, a storage box for storing heating mixture (asphalt) used for paving roads.

<Prior Art> For example, when a pavement road is dug back by a gas pipe construction, it is required to pave the dug back portion with a heating mixture after the construction to restore it.

By the way, the heating compound is usually used at a temperature of a hundred and several tens of degrees Celsius, and if the temperature becomes about 110 ° C. or less, it cannot be used even if it is reheated. However, the amount of heating mixture required is 100 to 200 kg.
In the case of small-scale construction, if the heating mixture is brought to the site in advance, it will cool quickly if the amount is about 100 to 200 kg, so it will cool to 110 ° C. or less when actually used. Therefore, in practice, it is necessary to handle a heating mixture with an amount of about 500 to 1000 kg that has a sufficient heat retaining capacity. In other words, about 80% of the actual purchase is wasteful as the material itself and wasteful processing costs.

Under these circumstances, in the case of small works, the current situation is that the restoration is carried out at room temperature composite material first, and then the work is carried out again by heating composite material. However, this entails a waste of work as well as a certain amount of waste of materials.

<Problems to be Solved by the Invention> Therefore, in order to solve such a conventional problem, the present invention can store even a heating mixture in an amount range required for a small construction while keeping the usable temperature. It is intended to provide such a heating mixture storage box.

<Means for Solving the Problems> Specifically, an outer frame in which a plywood is attached to the outer surface of a skeleton frame formed of a metal pipe, an inner frame formed of the plywood and appropriately hollowed, and a metal plate. There is provided a heating mixture storage box in which the above inner frame is combined in a nesting manner, and a heat insulating material is filled between the outer frame and the inner frame and between the inner frame and the inner frame, respectively.

<Operation> In this heating mixture storage box, the one formed by adhering a plywood to a skeleton frame made of a metal pipe is used as an outer frame, and an intermediate frame made of plywood provided with an appropriate hollow is interposed, It has a specific gravity of about 1.3, which is strong enough to withstand the weight of the heat-mixed material, and is lightweight, making it easy to handle when empty.

Further, in this heating mixture storage box, a more efficient heat insulating property is obtained by adopting a two-layer heat insulating material structure in which heat insulating material is filled between the outer frame and the inner frame and between the inner frame and the inner frame, respectively. Therefore, the heat retaining effect at a high temperature of hundreds of tens of degrees Celsius is realized.

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings.

The heating mixture storage box 1 includes a main body 2 and a lid 3.

The main body 2 is obtained by combining the outer frame 5, the middle frame 6 and the inner frame 7 in a nesting manner and filling a heat insulating material between the outer frame 5 and the middle frame 6 and between the middle frame 6 and the inner frame 7, respectively. The outer diameter is 5 in length.
48mm, width 448mm, height 274mm, inner diameter is 480m vertically so that the upper part has a tapered shape
The m is 400 mm wide, the bottom is 430 mm long, 350 mm wide, and 235 mm high, and it has a capacity to store about 50 kg of a heat mix with a specific gravity of about 1.3.

The taper shape of the inside of the lower portion is formed in this manner in order to facilitate the taking out of the heated mixture.

The outer frame 5 forms a skeletal frame 8 of a rectangular metal rectangular pipe of 24 mm square, a plywood 9 is provided on the outer surface of the skeletal frame 8, specifically, a plywood 9 a having a thickness of 9 mm on the side surface, and a bottom surface. Thickness 12
mm plywood 9b is attached to each.

The middle frame 6 is formed by using a plywood plate having a thickness of 9 mm on the side surface and a plywood plate having a thickness of 12 mm on the bottom surface, and is formed in a tapered shape with a lower concavity. 10, ... are provided. Here, the taper shape of the lower concavity is to make the inside have the same shape as described above.

The inner frame 7 is formed of a stainless steel plate having a thickness of 0.5 mm and has a shape similar to that of the inner frame 6.

The thickness of the heat insulating material 11 between the outer frame 5 and the middle frame 6 is about 25.
mm rock wool is used, and as the heat insulating material 12 between the inner frame 6 and the inner frame 7, glass wool having a thickness of about 3 mm is used.

Reference numeral 13 in FIG. 3 is a reinforcing frame for reinforcing the ridgeline of the main body 2, and 19 in FIGS. 1 and 2 is a handle.

The lid 3 forms a skeleton frame 15 with a square metal pipe of 24 mm square, and a 0.5 mm thick stainless steel plate 16 is attached to the outer surface of the skeleton frame 15, and a 9 mm thick plywood is attached as a top plate 17, and It is formed by filling the space formed in the above with the heat insulating material 18 using rock wool.

The top plate 17 is configured such that one side thereof protrudes larger than the outer frame 5, and this protruding portion serves as a “handle” when the lid 3 is opened. The reason for doing this is that if a "handle" such as a handle 19 is attached to the upper surface of the lid 3, the "handle" will be an obstacle when stacked, and the "handle" should be kept so as not to get in the way. The reason for this is that if it is embedded, the heat insulating property will be impaired accordingly.

In this heating mixture storage box 1, an outer frame 5 is composed of a skeleton frame 8 made of a metal pipe and plywood 9a, 9b attached to the outer frame 5, and a plywood interior 6 provided with hollows 10, 10 ,.
By interposing, the specific gravity is about 1.3, which is strong enough to withstand the weight of the heat-mixed material, and the weight is reduced, which makes it easy to handle in an empty box.

In addition, in this heating mixture storage box 1, heat insulating materials 11 and 1 are provided between the outer frame 5 and the middle frame 6 and between the middle frame 6 and the inner frame 7, respectively.
By having a two-layer heat insulating material structure in which 2 is filled, more efficient heat insulating properties are obtained, and a heat retaining effect at a high temperature of a hundred and several tens of degrees Celsius is realized. Specifically, under the temperature conditions in November in Tokyo, heating mixture of 180 ° C (recycled Astencock material) was added for about 1 hour and then about 1 hour.
It was kept at a temperature of 35 ° C., which was enough for use.

<Effects of the Invention> As described above, the heating mixture storage box according to the invention has an outer frame in which a plywood is attached to the outer surface of a skeleton frame formed of a metal pipe, and a hollow formed by the plywood as appropriate. The inner frame and the inner frame made of a metal plate are combined in a nesting manner, and the heat insulating material is filled between the outer frame and the inner frame and between the inner frame and the inner frame, respectively. Therefore, the specific gravity is about
It has the strength to withstand the weight of the heating mixture of 1.3 and is lightweight, so it is easy to handle when it is empty, and the heat insulating material is filled between the outer frame and the inner frame and between the inner frame and the inner frame. It has a two-layer heat insulating material structure and has a heat retaining effect at a high temperature of a hundred and several tens of degrees Celsius, and is optimal for keeping the heat retaining mixture.

Therefore, by using this heating mixture storage box, it is possible to maintain a sufficient usable temperature even with a heating mixture in the range of the amount required for small construction, and save waste of materials and work as in the past. The small construction can be rationalized.
