Description

Composite Panel Water Tank {COMPLEX PANEL WATER TANK}

The present invention relates to a composite panel water tank, and more particularly, to a composite panel water tank to combine a polyethylene composite panel by a welding method, and to install a steel frame on the outside to withstand water pressure.

Generally, a water tank is used to store a certain amount of water inside and supply it to buildings with high use of living water, such as residential apartments and business buildings. Depending on the material, a stainless steel panel tank, a synthetic resin (SMC) panel tank, and concrete It is classified into a tank and the like.

In such a tank, the stainless panel tank has an advantage of complementing the construction problem of the concrete tank, there is an economic problem due to the rise of raw material prices, synthetic resin (SMC) panel resin has a weak durability problem. In addition, in the case of the concrete tank, there is an advantage in that the structural strength and durability corresponding to the hydraulic pressure or bending load is excellent, but the work process is complicated, such as to cast concrete to form the curing to form the concrete tank, and then to remove the formwork. Not only that, there is a problem that requires a lot of construction period.

Recently, a number of tanks are manufactured using unit panels made of synthetic resin, which is a light and cheap material.

1 is an exploded perspective view showing the structure of a water tank according to the prior art, Figure 2 is a cross-sectional view showing the structure of the wall surface of the water tank according to the prior art.

As shown in Figures 1 and 2, the water tank 10 according to the prior art forms a water storage space using a plurality of unit panels 11, the outside is provided with a steel frame 12 that can support the water pressure do.

Steel frame 12 and the panel 11 is fixed by a fastening means 14, such as bolts or nails.

The upper surface is provided with a lid 13 to prevent foreign foreign matter from entering the water, the lid 13 may be formed with an inlet (not shown) for introducing water.

The panel 11 made of synthetic resin is in direct contact with water, forming sidewalls and bottom surfaces of the water tank 10, and water may be contaminated by raw materials contained in the synthetic resin.

In order to prevent such contamination, polyethylene (PE) sheet 15 is fused to an inner wall of the storage space formed of the panel 11.

The polyethylene sheet 15 is widely used in most synthetic resin panel water tanks because it does not cause contamination even when it comes in contact with water and prevents the stored water from leaking into the gap of the panel 11.

However, in order to attach the polyethylene sheet 15, a polyethylene sheet 15 having a thickness of about 2 to 10 mm should be manufactured and fixed to the inner wall surface by using an adhesive or a fastening means in the water tank 10.

And the end portion 15a of the sheet 15 is bonded to each other by a predetermined distance to prevent the leakage of water through the boundary portion where the polyethylene sheet 15 is in contact with each other.

This work requires a lot of time and effort, so the production period of the water tank is long and there is a problem that the manufacturing cost increases.

In addition, the panel 11 is not firmly coupled to each other to produce a water tank 10, but to install a steel frame 12 to support the panel 11 from the outside to support the water pressure from the outside, steel frame The size of the frame 12 was inevitably larger.

That is, each panel 11 receives a force in a state fixed only to the outer steel frame 12, the water leaks into the gap between the panels 11 is prevented by the polyethylene sheet (15).

Therefore, excessive pressure is added to the steel frame 12, there was a problem that the safety is lowered.

The present invention is to solve the above problems, an object of the present invention is to provide a composite panel water tank that can prevent the outflow of water without attaching a separate polyethylene sheet by combining the synthetic resin panels by welding.

In addition, the present invention is to provide a composite panel water tank that can prevent the breakage or cracking of the water tank by allowing the synthetic resin panels to be welded to each other to support the pressure of the stored water to a large extent.

In addition, the present invention aims to provide a composite panel water tank that can reduce the production cost and shorten the manufacturing period by removing the polyethylene sheet used by fusion in the water tank.

The present invention for solving the above problems is a water tank in which a water reservoir is formed, and a plurality of hollows are formed in the inside, and the inside and the outside are made of polyethylene raw materials in a regenerated state and a pure raw material, respectively, and welded together. A composite panel made of polyethylene coupled to each other to form sidewalls and bottoms of the reservoir; It is coupled to the composite panel by a fastening means, and the steel frame to support the water pressure of the water stored in the reservoir while being in contact with the outer wall surface of the reservoir formed by the composite panel; consists of a constant on one side of the composite panel An insertion protrusion protruding by a height is formed, and an opposite side is formed with a recess groove into which the insertion protrusion is inserted, and a gap between two adjacent polyethylene composite panels in a state where the insertion protrusion of the composite panel adjacent to the recess groove of the composite panel is fitted. Melted in the polyethylene welding rod is welded in such a manner that the fastening means penetrates diagonally from the inside of the concave groove of the composite panel toward the outside of the storage space while a part of the head protrudes into the concave groove. It is characterized in that fixed to the steel frame.

According to the present invention, when making a water tank with a plastic panel, it is not necessary to attach a separate polyethylene sheet to the inner wall in contact with water, thereby reducing the manufacturing cost and the production period is reduced.

In addition, according to the present invention, since the panels welded to each other can withstand a considerable size of water pressure, the safety of the water tank is secured even if the size of the external steel frame is reduced.

Referring to Figures 3 and 4, the water tank 100 of the present invention is made of a combination of a plurality of composite panels 102, and has a rectangular parallelepiped reservoir.

The composite panel 102 is in direct contact with water while forming sidewalls and bottoms of a rectangular parallelepiped reservoir. The material, structure, and bonding method of the composite panel 102 will be described later.

A lid 104 is placed on the upper surface of the reservoir, and the lid 104 may be provided with an opening / closing window (not shown) for inputting water or cleaning the inside of the water tank 100.

Steel frame 106 is installed on the outer wall of the storage space formed by the composite panel 102. Steel frame 106 is installed in contact with the outer wall surface of the composite panel 102 forming the reservoir space serves to support the water pressure of the water stored in the reservoir space.

Since the composite panel 102 is made of synthetic resin, when a large amount of water is stored in the storage space, the side wall may be slightly bent outward by water pressure. If the hydraulic pressure is increased or the support strength of the side wall is low, the water tank 100 may be damaged. To prevent this, the steel frame 106 made of steel is reinforced on the outer wall of the composite panel 102. It is.

The composite panel 102 and the steel frame 106 are fixed by fastening means such as bolts or nails, which will be described later.

The composite panel 102 forming the water tank 100 of the present invention is made of a synthetic resin of polyethylene (PE) material. The composite panel 102 refers to a panel having different internal and external raw materials.

As shown in FIG. 4, the composite panel 102 used in the present invention has a plurality of hollows 102a formed in the longitudinal direction therein, and the hollows 102a are continuously formed in the longitudinal direction of the composite panel 102. A plurality of composite panels 102 are formed in the width direction of the composite panel 102. The size of the hollow 102a and the number of the hollow 102a in the width direction may vary depending on the width of the composite panel 102.

It is preferable that the cross section of each hollow 102a has a substantially square shape, but may have a circular, elliptical, or rectangular shape depending on the application.

In addition, a plurality of hollows 102a may be formed in the thickness direction of the composite panel 102, and a plurality of hollows 102a may be formed in both the width direction and the thickness direction to form a grid pattern.

The inner body forming the hollow 102a of the composite panel 102 and the outer surface in direct contact with water are all made of polyethylene (PE) as a raw material, but constitute a slightly different state.

As shown in Figure 5, the inner body (A) is formed using polyethylene in a regenerated state, and the outer surface (B) uses a polyethylene in a pure raw material state.

The net raw material state refers to a state in which the polyethylene raw material has never undergone a heat conversion process, and the regenerated state refers to a state in which the polyethylene raw material is formed into a final synthetic resin product through heating.

As the polyethylene raw material is regenerated, impurities increase, and strength and rigidity become greater than those of the initial pure raw material.

Therefore, when the molding using the recycled raw material in the inner body (A), the strength of the inner partition is harder than the outside, it can withstand higher pressure or impact. In addition, in the case of recycled raw materials, the melting point is lower than that of the net raw materials, so the cooling rate is increased, thereby shortening the panel production time.

And, since the outer surface (B) is a portion exposed to the outside may be coated with various colors for aesthetics, there is a characteristic that it is more easy to color in the pure raw material.

In addition, the water tank 100 should be made of a component that is harmless to the human body directly in contact with the water, in the case of a pure raw material is less impurities and less risk of contamination.

On the other hand, both sides of the composite panel 102 is formed with a structure for coupling the panels. On one side of the composite panel 102 is formed an insertion protrusion (102b) protruding by a certain height, the opposite side is formed with a recess groove (102c) into which the insertion protrusion (102b) is fitted.

Since the width of the insertion protrusion 102b and the recess groove 102c is almost the same, the insertion protrusion 102b is fixed while being inserted into the recess groove 102c. In this manner, the multiple composite panels 102 may be coupled to each other to form a storage space.

6 to 8 illustrate a method of fixing by combining two adjacent composite panels 102.

First, as shown in FIG. 6, the composite panel 102 having the concave groove 102c is fixed to the steel frame 106 by the fastening means 110. The fastening means 110 may be used, such as bolts, screws, nails.

At this time, the fastening means 110 penetrates diagonally outward from the inside of the recessed groove 102c of the composite panel 102 to be fixed to the steel frame 106. Then, the flat head of the fastening means 110 is slightly protruded from the recessed groove 102c.

Then, the insertion protrusion 102b formed in the adjacent composite panel 102 is inserted into the recessed groove 102c as shown in FIG. 7.

Then, the distal end portion of the insertion protrusion 102b touches the head of the fastening means 110 and no longer enters. As a result, some space is created between the two composite panels 102.

Finally, as shown in FIG. 8, the two composite panels 102 are joined while welding the two composite panels 102 with a polyethylene welding rod. Welding is preferably done on the inner wall of the reservoir (the wall in contact with water). This is because the outer wall surface is already supported by the steel frame 106. In addition, when the composite panel 102 is slightly bent to the outside due to the internal water pressure, the gap is widened to prevent cracks from occurring. In addition, the welded part has a greater elasticity than the wall surface, and may also act as a buffer when deforming. Also, since the same polyethylene raw material is used, the antibacterial effect is also greater.

Since the gap between the two composite panels 102 is closed by the side of the insertion protrusion 102b, heat does not escape to the outside when the welding rod is inserted. Due to this, the welding rod is firmly adhered while being dissolved in the gap between the two composite panels 102.

In this way, welding the gaps between all the composite panels 102 not only forms a storage space, but also prevents water leakage without attaching a separate polyethylene sheet, thereby reducing manufacturing costs.

In addition, unlike the prior art in which the panels were simply glued together, a more rigid coupling is achieved by welding, and even if there is no steel frame 106 on the outside, it can support a certain amount of water pressure (about 1/3 of the total water pressure). There are advantages to it.

Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the technical configuration of the present invention described above may be modified by the person skilled in the art to which the present invention belongs without changing the technical spirit or essential features of the present invention. It will be appreciated that the present invention may be practiced as.
