Description

Internal non-reinforced PDF water tank construction method}

The present invention relates to the construction of an internal non-reinforced PDF water tank, and more specifically, to an internal non-reinforced PDF water tank used as a liquid storage facility that improves the structural composition to strengthen the mechanical strength of the structure in the construction, component parts manufacturing process, and water tank composition. Reinforcement PDF This is about the water tank construction method.

In particular, it concerns the side structure, which is the wall part, which is an important structure of the liquid storage facility, and the floor structure that supports the spread of the side structure. The floor structure is made of metal steel structure for the sake of mechanical strength and economical construction. The central part consists of a floor structure composed of PDF panels that do not require a metal frame and bolt assembly structure, and a wall structure composed of PDF panels that are directly connected to the upright side external pillars and cannot be welded and bolted, strengthening the mechanical strength of the side structure. Therefore, there is no internal horizontal reinforcement structure and a side structure that responds to the sloshing and buzzing of liquid caused by earthquakes was designed to reduce material usage, simplify parts manufacturing, and perform the construction process economically. Metal and non-metal materials are used. It is about a construction method for manufacturing a non-reinforced liquid storage facility inside a PDF panel structure to maintain mechanical strength, facilitate the formation of a waterproof layer inside, and respond to sloshing and buzzing during an earthquake.

In general, the reinforced concrete structure used in large-scale residential facilities, schools, hospitals, etc. for external drinking water storage facilities is a very stable structure. However, due to water leaks due to cracks and difficulties in managing the internal waterproof layer, there is a trend to replace them with lightweight prefabricated water tanks.

As an example, in previously disclosed Patent No. 10-2179908, a plurality of supports supporting the bottom unit panel of the water tank and arranged at intervals corresponding to the shape and size of the unit panel; It includes a plurality of connection frames interconnecting the plurality of supports, wherein the connection frame consists of a straight section extending in a straight direction and an inclined section extending in a bent direction from both ends of the straight section in a downward direction. , an upper and lower pedestals having a wider size than the pedestal are formed at the upper and lower ends of the strut, the straight section of the connection frame is located higher than the upper pedestal, and the end of the inclined section is located lower than the upper pedestal. The location technology has been previously presented.

In addition, in another prior art, Patent No. 10-2177024, foundation pillars arranged at intervals in the longitudinal and transverse directions on the ground; a floor plate portion installed on an upper portion of the foundation pillar portion and forming a floor surface by connecting a plurality of floor plates; A wall plate section having H-beams erected at intervals along the outer circumference of the floor plate section and a PDF panel interposed between the H-beams; And it is installed on the upper part of the wall plate and forms a roof by connecting a plurality of top plates, and the wall plate portion is installed on the H-beam and reinforces and supports the surface of the PDF panel in the transverse direction. A technology has been registered that includes a panel support fixing means that can install or dismantle the PDF panel sandwiched between the H-beams in the front and rear directions of the H-beam.

However, the prior art is intended to significantly improve seismic strength without constructing a separate reinforcement frame by improving the structure of the connection frame that interconnects multiple supports, but relies on welding and ball body fastening in the field along with the diversification of parts. Because it is assembled separately, on-site constructability is lowered, and in particular, as assembly precision is required, there is a disadvantage in that there is severe variation in quality (structural stability, cracking, waterproofing failure) depending on the worker's skill level.

The internal reinforcement structure of a typical PDF water tank includes the connection relationship between the PDF panel and the structural frame, which acts as a water barrier that affects structural safety in the event of an earthquake, and the protruding portion of the joining bolt, which is problematic when constructing the waterproof sheet that constitutes the internal waterproof layer. Processing, the problem of the reinforcement structure of the lower part of the external side pillar, which is important in constructing the external lattice structure frame to form the structural strength of the internal unreinforced hexahedral structure, and the problem of solving problems in the construction of waterproofing sheets of the reinforced haunches of the lower part of the reinforced external side pillar, etc. I came up with an idea.

In all of the above technologies, when a reinforced concrete PAD, which is a water tank holding structure, is applied after assembling a metal floor structure, it is very difficult to fix the anchor between the floor structure and the PAD, and there is a problem with the process of attaching all metal floor panels with bolts. of technology; The floor structure is made of metal for parts that require mechanical connection, and PDF panels are used for parts that simply receive vertical loads to improve economics and constructability. The structural frame including the side external pillars and the side wall have no protruding PDF panels for fixing them. By preventing the joint bolts from protruding, problems in constructing the waterproof layer are eliminated.

In addition, the joint structure of the external column and pillar is composed of a honeycomb structure to prepare for earthquakes by combining two structures: one that utilizes the tensile force of metal, and the other that prevents deformation of the side wall by expanding the contact gap between the external column and the side wall PDF panel. The structure was designed.
