Description

Manufacturing device of precast concrete wall plate with wing wall and manufacturing method of precast concrete wall plate by it {PRODUCTION OF PRECAST CONCRETE WALL UNIT WITH WING WALL AND PRODUCTION METHOD OF THE PRECAST CONCRETE WALL}

The present invention relates to a structure of a manufacturing apparatus for mass-producing a concrete wall plate of a vertical member for forming an outer wall and an inner wall of a building in a factory, and a method of manufacturing a precast concrete wall plate using the same.

The precast concrete (PC) method makes vertical members such as pillars and walls of a building and horizontal members such as beams and slabs at the factory and transports them to the site. Make it possible. Therefore, it is possible to reduce cost, secure high quality, and shorten construction period, so its application is on the rise rapidly.

1 shows each process of manufacturing a concrete wall plate using a precast method.

The factory manufacturing method of the concrete wall plate is usually made in a horizontal manufacturing method as shown in FIG. The horizontal manufacturing method is: ⅰ) Install a four-sided maguri mold on a steel table, ii) reinforce wall reinforcement inside, and iii) pour concrete when reinforcement is completed, and iv) create a pouring surface (top). Finish the plastering, ⅴ) cure, ⅵ) when the curing of the concrete wall plate is completed, ⅶ) disassemble the Maguri mold, and ⅷ) remove the concrete wall plate and move it to the storage location, and place each concrete wall plate on the cradle for storage. .

However, such a horizontal manufacturing method requires a wide manufacturing space, and in particular, there is a problem in that the manufacturing time is lengthened due to the finishing of the plaster.

A vertical manufacturing method has been developed as a way to solve the above problems of the horizontal manufacturing method.

The vertical production method uses vertical molds divided into several compartments with vertically erected steel shutters in between. The production of concrete wall plates by this is: i) open one space of the vertical mold, ii) install the vertical maguri mold on the side of one shutter, iii) install the wall reinforcement, and then iv) move the other shutter to maguri The compartment is narrowed so that the mold is closed, ⅴ) When the preparatory work for pouring concrete for the entire compartment is completed by repeating each of the above operations i) to iv), ⅵ) pouring concrete into each compartment through the open top And ⅶ) after curing them, ⅷ) open one shutter in sequence one by one, ⅸ) remove the concrete wall plate and take it out of the vertical mold, move it to the storage place, and place each concrete wall plate on a cradle for storage.

This vertical manufacturing method is not only capable of simultaneously manufacturing many concrete wallboards in a narrow space, but also very economical because it does not require plastering and finishing work.

However, all concrete wall plates manufactured by the vertical manufacturing method including the conventional horizontal manufacturing method described above have a two-dimensional flat plate shape.

Such flat-shaped precast concrete wallboards have a disadvantage that when the wallboards are joined in a'L' or'T' shape, the joint treatment is more difficult and structurally weaker than when they are joined in a'ㅡ' shape.

In addition, when assembling them in the field and constructing the wall, as shown in Fig. 2, it is necessary to install a brace until it is completely self-standing and erected through a combination with other vertical members, and thus the brace blocks the movement of workers. As a result, there is a problem that interference occurs in other work and there is a lot of room for safety accidents of workers.

In addition, since it has been manufactured and is not self-reliant even when stored, it is necessary to use a cradle, which incurs additional costs for a lot of space and storage facilities.

However, in the case of obscuring or obscuring the technical idea of the present invention due to a detailed description of a known configuration in the description of the present invention, a description of the known configuration will be omitted.

FIG. 3 is an overall view of the manufacturing apparatus 100 according to an embodiment of the present invention, and FIG. 4 is an enlarged view of part A of FIG. 3, and one bay 200 in which one wall plate 10 is manufactured. It shows the inside of.

The manufacturing apparatus 100 of the present invention is a vertical vertical plate mold 120 for simultaneously forming a plurality of shutters 110, a main wall 11, and a wing wall 12 perpendicular thereto, as shown in FIGS. 3 and 4 And, it consists of a side edge mold 130 and a bottom mold 140.

The shutter 110 serves as a form for the end surface of the wing wall 12 in a portion where the inner vertical plate mold 120 is not installed while providing an installation space for the inner vertical plate mold 120 and the side edge mold 130.

As shown in Fig. 3, a plurality of shutters 110 are installed in parallel, and each of the shutters 110 is independently vertically positioned along the moving rail 180 installed on the floor plate of the workplace so as to overlap each other. It is installed to be movable in any direction.

Therefore, a plurality of bays 200 may be continuously formed between the shutters 110, and the bay 200 may form a concrete placement space 210 for manufacturing the wall plate 10, and the shutter ( While moving 110, the above-described molds 120 and 130 can be sequentially installed in each bay 200.

The shutter 110 may be configured in a structure in which two divided first and second half shutters 110A and 110B are assembled as shown in FIG. 6. Each of the first and second half shutters 110A and 110B has a receiving space 112 open to the outside, and at least one of the receiving spaces 112 has a curing means 170 such as a heating wire or a hot water pipe. It may be disposed, and the first and second half shutters 110A and 110B are mutually assembled through a fitting method or the like to have the same shape as the integral shutter 110.

The internal vertical plate mold 120 is configured to be detachably attached to the inner surface of the central portion of the shutter 110, and the structure of the shutter 110 in each of the above-described embodiments is according to the method of attaching the internal vertical plate mold 120 to be described later. Applied appropriately.

For example, the attachment of the internal vertical plate mold 120 to the inner surface of the shutter 110 may be performed by an attachment means 160 such as a magnet or a fastening bolt, and the front surface of the internal vertical plate mold 120 is the main wall 11 to be manufactured. Since it forms the outer surface of the body, there is a limitation that the front surface of the internal vertical plate mold 120 must have a smooth surface. In addition, since both sides of the shutter 110 form the end surfaces of the wing walls 12, both sides of the shutter 110 need to have smooth surfaces. Therefore, the shutter 110 and the attachment means 160 of the inner vertical plate mold 120 need to be formed in a structure that does not protrude to the outside.

As shown in FIG. 5, when the shutter 110 is integral, the attachment means 160 is installed inside the inner vertical plate mold 120. In this case, the internal vertical plate mold 120 is made of a polygonal frame 121 and a plate material 122 attached to the outer surface of the polygonal frame 121, and installation and removal of the attachment means 160 is performed from the polygonal frame 121.

The wing wall 12 formed perpendicular to the main wall 11 varies according to the arrangement of the internal vertical plate mold 120 attached to the inner surface of the shutter 110. In addition, the length of the wing wall 12 varies depending on the thickness of the inner vertical plate mold 120. FIG. 7 is a diagram illustrating a wall plate 10 in a state in which the wing walls 12 of various shapes are formed on the main wall 11 and each arrangement state of the internal vertical plate mold 120 therefor.

8 is a diagram illustrating a state in which a side edge mold 130 is installed on the shutter 110.

The side edge mold 130 is disposed on the inner surface of the rim of the shutter 110 to set the left and right ends of the wall plate 10 to be manufactured. That is, the side edge mold 130 is installed vertically on both side ends of the inner vertical plate mold installed on the inner surface of the shutter 110, and functions as a formwork for the end surface of the main wall 11 or the rear surface of the wing wall 12. In the side edge mold 130, concrete is poured only into the inner vertical plate mold 120 and the outer side is exposed. Unlike the method of attaching the inner vertical plate mold 120, a magnet or fastening bolt on the exposed portion It is possible to attach the side edge mold 130 to the inner surface of the shutter 110 by installing an attachment means 160 such as.

The side edge mold 130 attached to one shutter 110 is in close contact with the inner surface of the other shutter 110 or the inner vertical plate mold 120 attached thereto, thereby completing the closing of the left and right sides of the concrete placement space 210.

9 and 10 are respectively shown with respect to the floor mold 140 for closing the lower portion of the concrete placement space 210, Figure 9 shows the support means 150 for installing the floor mold 140 , FIG. 10 shows a process in which the bottom mold 140 is mounted on the support means 150 and installed under the bay 200.

The support means 150 for supporting the floor mold 140 is installed under the shutter 110 so as to move up and down.

The top and bottom lengths of the wall plate 10 to be manufactured are from the top of the shutter 110 to the top of the bottom mold 140. Therefore, the floor mold 140 sets the lower end of the wall plate 10, and the floor mold 140 also moves up and down according to the vertical movement of the support means 150 to correspond to the length of the wall plate 10 to be manufactured. It makes it possible to manufacture the wall plate 10 of various standards.

The vertical movement means of the support means 150 may be configured in various structures. According to the embodiment of Figure 9, the slit groove 113 is provided in the vertical direction on the side of the shutter 110, the support means 150 is provided with a moving platform 152 moving along the slit groove 113 In addition, a mounting piece 151 for mounting the bottom mold 140 is fixedly installed on the moving platform 152 toward the inner surface of the shutter 110.
