Description

  In particular, in the production of large corrosion-resistant containers such as stainless steel, it is possible to prevent the occurrence of distortion by using as thin a steel plate as possible to be bonded to the outer surface or inner surface of the mold, and to reduce the number of welding steps. The present invention relates to a large container formed to be downable.

  In the case of manufacturing containers that require airtightness using corrosion-resistant materials such as stainless steel, conventionally, even non-pressure containers can be made using steel plates with a predetermined thickness to prevent distortion caused by continuous welding of steel plates. It was. In addition, for large containers exceeding the transport limit, a scaffold was assembled at the installation site to form a formwork, and due to the continuous welding method, material costs and man-hours were increased.

  The present invention has been devised by paying attention to the above-mentioned problems. For example, in the case of the stainless steel large airtight pressureless container, at least the upper body is not distorted by using a thin steel plate and is continuously welded. In order to reduce the number of man-hours and reduce the number of man-hours, the joints of the rectangular peripheral edge of the outer wall steel plate are arranged so that they can come into contact with the angled surface and the right-angled part of the formwork. Large container that exceeds the transport limit at the same time as the construction of thin plate large-scale can technology that can be used for caulking work without causing anxiety of external damage using a viscous coking material and seal cover at the joint However, it is an issue that the factory work is divided so that it can be transported and the field work after the field assembly is limited to the caking work.

Means to solve the problem

In order to achieve the above object, the present invention, for example, a corrosion resistant steel plate such as stainless steel for forming a deodorizing device by atomizing a functional liquid such as ozone water in a predetermined large container and gasifying reaction with the original odor gas. To reduce the cost of steel by using an airtight, non-pressure large-sized square container made of as thin as possible for the outer wall steel sheet, and to reduce the man-hours by reducing the man-hours by establishing a method that eliminates the need for continuous welding The mainstream of this container is efficient factory production, or large containers that exceed the transport limit are divided into a plurality of transportable blocks and are intended to be handled by a prefabricated method that can be assembled on-site after transport. An airtight large container is mainly composed of an upper trunk and a lower liquid pool drip pan, and the lower drip pan is a continuous welding method using a predetermined plate thickness, and at least the upper trunk from the ground forming the container. A square sheet steel plate serving as an outer wall is pasted on the outer surface by arranging the angle of the formwork on the outside or on the inner surface so as to be able to arrange joints with each of the four peripheral edges abutted, and The vicinity of this joint is securely joined to the mold by spot welding or rivet joining without distortion, and the caulking is applied to this joint using a separately-formed concave seal cover with double-sided flanges. After injecting the caulking material into the concave portion, it can be crowned and joined, and the hooks on both sides can be spot-bonded intermittently or instantaneously bonded to perform coking so as to be kept airtight.
The large container formed in this way is cut into the outer surface of each angle of the container forming mold, for example, a stainless steel square plate having a thickness of 1.0 to 1,5 mm, or a predetermined size. A joint that has four sides of the thin steel plate butted together is placed, and holes of about 5 millimeters are drilled at regular intervals on both sides along the joint, and there is no angle and distortion by spot welding or rivets. The joint is securely joined, and, for example, a caulking material such as silicone is injected into the joint using a steel concave cover with a flange, and the crown is joined to the seal cover. A large container can be formed by spot welding or spot-bonding and fixing the joint after sealing. In this case, the bottom drip pan is mainly provided at a thickness of 2, 0 to 2,5 mm to ensure waterproofing as a continuous welding method, and the drip pan and the upper body are connected in the horizontal direction. The eyes can also be integrally formed by spot welding through the same shape steel or flange member as described above, and can be integrally formed by performing a caulking operation. In addition, the seal cover which provided the cross section in the square shape can be used for the butt | matching part of the angle corner | angular part of the ceiling part periphery.

  Accordingly, the non-pressure-tight airtight large container made of a thin steel plate such as stainless steel that does not require continuous welding of the upper shell outer wall steel plate of the present invention formed in this way is not only a transportable container, but also a large container exceeding the transport limit. For example, it can be loaded into a trailer, divided into blocks of about 2,9 meters in width, 9,5 meters in length, and 3 meters in height, manufactured at the factory, and bolted and nuted using a tow truck at the site after delivery. In addition, it is possible to construct a large container by assembling and caulking the joint at the site. Therefore, in the case of an airtight container that does not require continuous welding using a thin steel plate such as a stainless steel, if the strength against the internal pressure or the external pressure is not so much required, the plate thickness is approximately within 10 mm to 1.5 mm. Because it is possible to manufacture without distortion, not only the material cost is reduced, but also the welding man-hours, which has been a costly factor in the past, can be greatly reduced by combining with the above-mentioned coking method, and coking of silicone etc. The seal part is made by covering the material with a seal cover that is separately molded in a predetermined single length to ensure airtightness, and by providing this cover with both ribs and spot-joining the flange with a steel plate It is possible to provide a thin stainless steel large-sized container that can be formed so as to be able to be rubbed and removed, to protect against trauma, and to prevent thermal dripping during summer construction, and to be excellent in appearance and design.

Further, according to the present invention, when the continuous welding drip pan is arranged at the bottom and the seam of the outer wall steel plate of the cylindrical stainless steel container is sealed using a viscous coking material such as silicone. In order to prevent scraping or damage of the seal part and thermal dripping during construction in the summer and to prevent dropping and damage, an inner fold-type recess with a predetermined gap formed on one side of the steel strip. A C-shaped seal cover flared into a bowl shape is provided and molded in a predetermined length. After the semicircular brazing is applied to the curved surface of the body, the coking material is injected into the recess. The crown is joined in the circumferential direction of the container and temporarily fixed with tape. The contact part of the external flare is spot welded to the steel plate to perform the caulking of the circumferential seam. , This C-shaped seal cover on the outer periphery of the ceiling has a square cross section Therefore, in the present invention, even in a stainless steel cylindrical container, by using a C-type seal cover, a thin plate can be used and manufacturing can be performed at a low processing cost with no need for continuous welding. As a result, it is possible to form an airtight large container that can greatly reduce the cost. In addition, the steel plate can be used for the reinforcing frame in the circumferential direction of the body portion, and at the same time, the joint between the drip pan and the upper body is joined to the steel plate steel or the angle material as in the first embodiment. Can be done through.

  Further, according to the present invention, as described in claim 3, the joining and sealing of the upper body outer wall steel plate in the internal gas body reaction square or cylindrical large container, the surface of the mold steel of the mold, or The seal groove is formed by connecting the four sides that form the joints of the steel plates to the right-angled part, the edge of the predetermined height at the ends of the opposite sides, and the groove of the predetermined width, and spot-joining both sides to the mold steel. The outer wall is formed so that the caulking material can be injected, and a corrugated strip with a resin-made wrinkle is mainly press-fitted on the upper surface of the caulking material after the injection, and the joint material is It is possible to form a thin plate hermetic large container that can be drastically reduced without the need for continuous welding of the upper shell provided to prevent dripping.

Effect of the invention

  The thin plate airtight large container that does not require continuous welding of the upper outer wall of the present invention is performed by spot-welding the vicinity of the steel sheet at a predetermined interval along the surface of the reinforcing angle of the joint of the steel sheet or the joint arranged at the right angle part. By joining and coking the viscous caulking material using the seal cover, the use of thin steel plate without distortion will reduce the weight, reduce the steel material cost, and greatly reduce the welding man-hours. It can be realized to provide a great economic effect, and can provide can manufacturing technology with excellent design. In addition, large containers that exceed the transport limit can be divided into transportable sizes, manufactured at the factory, and then can be made into airtight large cans by a prefabricated method using only bolt and nut assembly type coking.
