Abstract

The present invention discloses a method for manufacturing a method for manufacturing a concrete upper horizontal surface-treated rafter molding mold, and the concrete upper horizontal surface-treated rafter molding mold manufactured thereby. Since a horizontal surface is provided on the top of a manufactured molding mold body and horizontal surface treatment is performed on the upper part of placed concrete by a top cover which covers the upper part of the molding mold body to be in close contact with the horizontal surface, the contact with the bottom of the eaves of a Korean-style house is made by surface contact, the rigidity as well as durability and supporting force are greatly improved. In addition, as the horizontal surface treatment is performed on the rafter made of concrete, it is possible to prevent an operator from slipping when stepping on, thereby securing the work space of the operator, and the amount of placed concrete can be minimized by the horizontal surface treatment provided on the upper part of the rafter made of concrete. As the weight of the concrete rafter can be reduced, the workability as well as transport can be greatly improved, and the recycling of resources can be induced by tying a PVC molded pipe with a discarded bicycle waste tube. In addition, by tying PVC molded pipes so that no gaps are formed, the tightening power of the PVC molded pipe is improved so that a uniform molding mold body is formed. Furthermore, the method uses hot air, but heats the PVC molded pipe by indirect heat by allowing hot air to be transferred indirectly, so that it is possible to prevent the PVC molded pipe from being heated unevenly, the PVC molded pipe from being twisted, or the bicycle waste tube from being burned.

Description

The present invention relates to a method of manufacturing a concrete upper horizontal surface treatment softwood molding form and a concrete upper horizontal surface treatment softwood molding form manufactured by the manufacturing method, and more particularly, to reinforce the rigidity of the softwood and facilitate the construction of the softwood. Not only can the period be greatly shortened, but also the durability and supportability by surface contact between the softwood and the slab are greatly improved, and the weight reduction of the softwood is induced to reduce the weight of the softwood as well as to minimize the load on the softwood. The present invention relates to a method of manufacturing a concrete upper horizontal surface treatment softwood molding mold for use, and a concrete upper horizontal surface treatment softwood molding form manufactured by the method.

In general, a hanok building refers to a building constructed in a traditional Korean way.After performing the foundation work on the site to be built, a pillar is placed on the foundation stone and a pillar is erected on the pillar. The main skeleton is constructed by combining beams, and a roof skeleton consisting of softwood (rafters), flat arches, bulges, ridges, and ridges is constructed on the upper part of the main skeleton. Between the eaves and the ridge, the softwood is installed at an inclined shape in the shape of a fan, and roof tiles are placed on the softwood base.

Since such a hanok building is usually made of wood, there is a problem in that the material cost according to the construction of the building is burdened and the load on the roof becomes heavy, and the problem of twisting or cracking due to the nature of wood is caused.

On the other hand, a hanok building using softwood made of concrete structures has been proposed, but the softwood made of concrete takes a lot of load compared to wood, so it is difficult to transport as well as construction. There is a problem that safety is remarkably deteriorated due to vertical transmission.

In addition, a mold for manufacturing softwood with a conventional concrete structure is usually a mold made of PVC.

Looking at the prior art, there has been a precast concrete rafter of a traditional hanok, which is registered patent No. 10-1760072, a method for forming the same, and an apparatus for forming a molding frame. This is a method of manufacturing a traditional rafter using wood in the PC rafter manufacturing method. Step of manufacturing a rafter die by processing, butt the circular panel to the front end surface of the rafter die, fix it with nails, etc., install a fixing piece on one side of the outer circumferential surface of the rafter die end, and then apply FRP resin to the front end surface of the rafter die. Applying to a predetermined thickness to form an FRP ring cover provided with a flange, removing the FRP ring cover formed on the outer circumferential surface of the front end of the rafter die to cut one side of the larger diameter so that an inclined surface is formed, the Forming a plurality of front edge base molds by correspondingly fixing a circular panel on the side of the sloped side of the FRP ring cover and filling with synthetic resin through an opening on the flange side, forming a circular panel on both sides of the front edge base mold After the corresponding fixing, repeating the process of winding glass fiber around the outer circumference of the base mold between the circular panels to be impregnated with FRP resin to form a front edge molding frame having a predetermined thickness, and a pattern on one side slope of the front edge molding frame A step of forming a front edge with a flange by matching and fixing an absent barrier plate or a patterned woodblock and applying FRP resin to the floor and inner circumferential surface through the opening on the other side of the flange to form a front edge with a flange. The step of forming a PC rafter molding frame by inserting a wooden mold inside, tying it with a rubber band, applying heat, and then demolding it, and a bending reinforcement formed integrally with a plurality of band reinforcing bars bound to the main reinforcement inside the molded PVC rafter molding frame is provided. The step of embedding the rafter frame, installing a front edge with a flange on the inside of the front of the PVC rafter forming frame, installing the front edge with the flange, and then installing the main reinforcement so that the main reinforcement is fitted to the rear edge, and the PVC rafter Tying both ends of the molding frame with metal bands to install the rafter frame, In the precast concrete rafter forming method comprising the step of pouring concrete into the PVC rafter forming frame in which the rafter frame is installed and then curing and demolding the cured PC rafters from the forming frame, the step of forming the PC rafter forming frame, Prepare a PVC pipe with built-in rafters and cut them to match the length of both ends of the wood, and then form a notch in the longitudinal direction, insert the rafters to the inside and tie it tightly and evenly with a rubber band, and put it in an electric hot stove at 100℃. The step of heating at -130℃ for 20 to 40 minutes, turn off the power of the electric heater device of the electric hot stove heated for 20 to 40 minutes, lower the temperature to 90℃ or lower, and then take out the PVC pipe that is tied with a rubber band by inserting the rafters. It consists of demolding to form the PC rafter molding frame.

This prior art, when forming the PVC rafter molding frame, by forming the PVC rafter molding frame with hot air using an electric hot stove rather than hot water molding using water, reducing the preparation work time for the molding mold manufacturing and molding by a heater The mold forming time can be shortened.

However, in the case of the prior art, when the PVC rafter molding frame is formed by the hot air of the electric heating stove in a state in which the PVC pipe with the rafter wood is inserted into the electric heating stove, the heat of the hot air is directly transmitted to the PVC rafters. Due to this melting phenomenon, there is a problem that the PC rafters cannot be properly molded.

In addition, in the case of concrete rafters molded using the molding frame of the prior art, since the outer shape is made of a circular shape, slipping occurs when a worker steps on the rafters, as well as the appearance of a circular shape in the construction of a structured hanok building. Line contact with the bottom of the hanok eaves occurs due to the rafters made of, and thus supportability is greatly reduced, and there is a problem in that the load transmission of the building is not properly transmitted to the column side.

Moreover, in the case of the prior art, there is a problem in that the tightening force of the PVC pipe is lowered as the rubber bands that bind the PVC pipes are not tightly bundled and a space is formed between the rubber bands and the rubber bands.

Hereinafter, other objects and features of the present invention in addition to the above objects will be clearly revealed through the description of the embodiments with reference to the accompanying drawings.

Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs. Terms such as those defined in a commonly used dictionary should be interpreted as having a meaning consistent with the meaning in the context of the related technology, and should not be interpreted as an ideal or excessively formal meaning unless explicitly defined in this application. Does not.

Hereinafter, a method of manufacturing a concrete upper horizontal surface-treated softwood molding formwork according to an embodiment of the present invention and a concrete upper horizontal surface-treated softwood molding formwork manufactured by the method will be described in more detail with reference to the accompanying drawings.

As shown in the present invention, the present inventors concrete upper horizontal surface treatment softwood molding mold manufacturing method, the wood processing process (S1) of processing the softwood wood mold (10), the upper part of the PVC molded pipe 20 is cut, but the PVC molded pipe After opening the incision along the longitudinal direction of (20), the wooden mold receiving process (S2) in which the softwood wooden mold 10 processed by the wood processing process (S1) is inserted into the PVC molded pipe 20 and received, Molded pipe winding process (S3), the molded pipe winding process (S3) for winding the outer surface of the PVC molded pipe 20 in which the softwood wood 10 is accommodated by the wooden receiving process (S2) using the closed bicycle tube 30 A heating process (S4) of heating the PVC molding tube 20 in which the bicycle closed tube 30 is wound by the hot air using a hot air fan 40, and the PVC molding tube 20 heated by the heating process (S4). ) After cooling, it relates to a method for manufacturing a softwood molded mold provided as a finishing process (S5) of separating the wound bicycle closed tube 30 from the PVC molded pipe 20 to form the molded mold body 50.

The molding pipe winding process (S3) of the present invention is a PVC molding pipe by intimately closing the bicycle closed tube 30 so that a space is not formed with respect to the outer surface of the PVC molding pipe 20. 20) Wind it up to prevent it from spreading.

Accordingly, the waste bicycle tube 30 is used to wind the outer surface of the PVC molding tube 20, so that the effect of resource recycling can be expected, as well as the bicycle waste tube 30 is cut off in the heating process (S4). This can be prevented in advance, so that the defect rate in which the PVC molded pipe is not properly molded can be minimized as the rubber band is easily broken by heating after winding the PVC molded pipe with a conventional rubber band.

In the wood processing step (S1) of the present invention, the upper end of the softwood die 10 is face-treated to provide a horizontal wooden surface 11, and the front surface 12 of the softwood die 10 is applied to the lower end of the softwood die. It is made by processing inclined at a downward inclination angle (a), and processing the lower end 13 of the softwood die 10 to be inclined at an upward inclination angle (b) inclined toward the front side 12 of the softwood die 10.

The reason for processing the softwood wood mold 10 to have a downward inclination angle (a) and an upward inclination angle (b) is that the shape of the concrete softwood made of poured concrete is the same as that of the existing wooden softwood. It is to make it happen.

In addition, the present invention is to be provided with a horizontal surface 51 on the upper end of the mold body 50 separated from the PVC molding pipe 20, the upper end of the mold body 50, the longitudinal direction of the mold body 50 A horizontal surface processing process (S6) of the forming die body for cutting and cutting accordingly is provided.

The reason why the horizontal surface treatment process (S6) is provided in this way is that a horizontal surface is provided on the upper part of the concrete softwood made of poured concrete to perform the function of the worker's scaffolding to secure the worker's work space. This is to greatly improve durability and stiffness as well as support as well as durability and rigidity as the adhesion is closely adhered and supported by surface contact.This is because the conventional circular concrete rafters are in close contact with each other, resulting in slipping and reducing supportability. This is to prevent it.

In the present invention, before the heating process (S4), the tin plate 70 on the outside of the PVC molding pipe 20 is positioned on both sides along the longitudinal direction of the PVC molding pipe 20 so that the hot air of the hot air blower 80 is It is transferred to the tin plate 70 to heat the tin plate 70 at 50° C. for 30 to 40 minutes, so that the heating temperature of the tin plate 70 is transferred to the PVC molding pipe 20 and the PVC molding pipe 20 It is heated by the indirect heat of the hot air fan (80).

In this way, the bicycle waste tube 30 by direct heat is heated by the indirect heat transmitted indirectly by the tin plate 70, not by direct heat. It is possible to prevent the burning or the bicycle closing tube 30 from being damaged and broken, or the PVC molded tube 20 from burning or melting.

In addition, in the present invention, after connecting the rotation guide rod 91 to one side of the PVC molding tube 20 in which the bicycle closing tube 30 is wound, and connecting the rotation handle 92 to the other side, the rotation guide rod 91 ) And the rotary guide bar 91 and the rotary handle 92 are placed on the support 93 of the support 90 having the support 93 to which the rotary handle 92 is supported, and the PVC molding tube ( When 20) is indirectly heated, the rotation handle 92 is rotated so that the PVC molding pipe 20 is rotated so that the PVC molding pipe 20 is indirectly heated evenly as a whole.

In the process of heating the PVC molding pipe 20 by the indirect heat of the hot air fan 80 transmitted indirectly through the tin plate 70 as described above, turning the rotating handle 92 causes the rotation guide rod to be mounted on the support part 93 ( Since the PVC molding pipe 20 is rotated by 91), even indirect heat can be transmitted to the PVC molding pipe 20 as a whole, and accordingly, the bicycle closed tube 30 wound following the PVC molding pipe 20 Indirect heat can be evenly distributed and transmitted, so that the bicycle waste tube 30 is burned or the bicycle waste tube 30 is damaged and broken, or the PVC molded tube 20 is more reliably prevented from burning or melting. have.

As the support is closely contacted and supported by surface contact, durability and rigidity as well as support can be greatly improved.

In addition, as the upper surface of the cured concrete softwood is treated horizontally, the amount of concrete to be poured can be reduced compared to the conventional concrete rafters, thereby minimizing the weight of the concrete softwood. It can be greatly improved, and the load transfer transmitted to the column or beam can be minimized.

In addition, a first connection hole 153 is provided in the first upper cover 150, and a first connection hole 153 is provided in the second upper cover 160 to correspond to the first connection hole 153, 153) and a second connection hole 163 connected to the bolt is provided.
