Description

[DESCRIPTION]
[invention Title]
MOLD FOR MANUFACTURING U-TYPE SIDE GUTTER AND ITS MANUFACTURING METHOD USING THE MOLD
[Technical Field]
The present invention relates, in general, to a form assembly and method for manufacturing a side gutter, and more particularly, to a form assembly and method for manufacturing a U-type side gutter, in which the structure and installation of the form assembly for manufacturing the U-type side gutter are simplified, thereby enabling easy construction even if a worker is not skilled, a reduction in the period and cost of construction, and dimensional adjustment and assembly of the form assembly even if the dimensions of the U-type side gutter vary depending on the application and capacity of the U-type side gutter.
[Background Art] Generally, a U-type side gutter is finished by assembling inner and outer forms to define a U-shaped inner cavity, placing and fixing reinforcing bars in the inner cavity, pouring concrete into the inner cavity, curing the concrete for a given time, and removing the forms. The U- type side gutter is mainly used as a sewage passage for guiding the discharge of rainwater introduced through manholes, or as a cable tunnel serving to protect communication cables.
In the past, after a concrete foundation is built, the inner and outer forms are installed on the concrete foundation. At this time, in order to keep the forms straight, the forms are bound to long pipes. Further, a square bar is cut to support the gap between the inner forms in order to prevent the inner forms from twisting. This work is easily carried out only by a highly skilled worker who is experienced with the forms. The concrete foundation is built together with the U-type side gutter at different times, which causes cracks in the joint between the concrete foundation and the U-type side gutter and doubles the consumption of equipment and manpower. This consequently increases the cost of construction, and delays the period of construction cost .
Further, the height, width, etc. of the U-type side gutter are generally dependent on the usage or capacity of the U-type side gutter. The current forms cannot produce a U-type side gutter having various dimensions. It is not possible to adjust the length of stud bolts passing through the upsides of the inner and outer forms, and thus interval between the inner and outer forms cannot be maintained uniform. As a result, the installation of the forms is difficult in a place having a small work space. [Disclosure] [Technical Problem]

FIG. 10 a perspective view illustrating a U-type side gutter cured using the form assembly of FIG. 9.
First, referring to FIGS. 1, 2 and 3, the first embodiment of the present invention is directed to a form assembly and method for manufacturing a U-type side gutter. The form assembly for manufacturing a U-type side gutter includes a pair of inner forms 2 and 2' installed inside them such that the outer surface thereof has a "U" shape, and a pair of outer forms 1 and 1' installed outside the inner forms 2 and 2 ' so as to maintain a uniform interval . To this end, each anti-twist sleeve 10 is fitted around the corresponding stud bolt 30 such that it is located at the middle of the stud bolt 30, and then the inner forms 2 and 2', angles 3 and 3', angle support blocks 4 and 4', angle support sleeves 5 and 5' , and the outer forms 1 and 1' are sequentially assembled around the stud bolt 30 in opposite directions.
More specifically, each stud bolt 30, which is longer than the width of the form assembly of the U-type side gutter, is prepared, and the width of each anti-twist sleeve 10 which is located in the middle of the corresponding stud bolt 30, is set between those of the inner forms 2 and 2' . When the inner and outer forms are assembled using the sleeves, made from a steel pipe, the width between the inner forms 2 and 2' is prevented from being reduced.
Each of the inner forms 2 and 2' is manufactured by cutting a steel strap 35 for forms into two types of pieces, a short one and a long one, so as to meet desired standards, pressing the lower portion b of the cut short steel strap 35 to form a curve 31, welding the pressed short steel straps 35 and the impressed long steel straps 35 at their ends 9 to form a box-like frame 37, and riveting a cut plastic plate 39 to the frame 37 having the curve 31 using rivets 36.
Each of the inner forms 2 and 2' is provided with a plurality of stud bolt insertion holes 32 in an upper portion b thereof and has joint holes 19 formed therein at opposite longitudinal ends thereof.
Each of the angle support blocks 4 and 4 ' is made from a plastic cube, and is adapted to be assembled with each of the angles 3 and 3' in a manner such that a through-hole is formed in the plastic cube and the stud bolt 30 is inserted into the through-hole of the plastic cube, thereby preventing each of the angles 3 and 3' from twisting. Each of the angles 3 and 3' is several times as long as each form, and has a flange provided with the stud bolt insertion holes 32 so as to correspond to the stud bolt insertion holes 32 formed in the upper portion a of each form. Meanwhile, the angle support sleeves 5 and 5' are installed between the angle 3 and the outer form 1 and between the angle 3' and the outer form 1' , are made from plastic pipe, and match the width of a space 29.
Each of the outer forms 1 and 1' is manufactured by cutting a steel strap 35 for forms into two types of pieces, a short one and a long one, such that the cut long steel strap 35 is equal to the length of each of the inner forms 2 and 2' and such that the cut short steel strap 35 is longer than the width of each of the inner forms 2 and 2' and is equal to the height of the concrete to be poured on a foundation c, welding the cut short and long steel straps 35 at their ends 9 to form a box-like frame 37, and riveting a piece of plywood 40, which is cut as required, to the frame 37 using rivets 36. Each of the outer forms 1 and 1' is provided with a plurality of stud bolt insertion holes 32 in the upper portion a of the frame 37 thereof and with a plurality of anchoring holes 27, into which anchoring pins 25 or 25' are inserted in order to fix each of outer forms 1 and 1' to the ground, in the lower portion b of a lower flange 34 thereof, and has joint holes 9 formed therein at opposite longitudinal ends thereof .
Now, the method of manufacturing a U-type side gutter using the above-described form assembly will be described below. First, in the process of performing pit excavation in order to install the U-type side gutter, soil compaction is performed so that the middle of the bottom of the U-type side gutter, i.e. the ground 28 located below the lower ends of the inner forms 2 and 2', is lower than the ground 28 to which the outer forms 1 and 1' are fixed. The reason for making the ground 28 located below the lower ends of the inner forms 2 and 2' lower is to allow the concrete to smoothly flow to the lower ends of the inner forms 2 and 2' when the concrete is poured. Next, each anti-twist sleeve 10 is fitted around the corresponding stud bolt 30 until it reaches the middle of the stud bolt 30. The inner forms 2 and 2' are fitted around the stud bolt 30 in opposite directions such that the lower ends thereof, adjacent to the curves 31 thereof, are in contact with each other. Joint pins 23 and 23' are inserted into the form joint holes 19 in the lower ends of the inner forms 2 and 2', thereby fixedly coupling the inner forms 2 and 2' .
The angle support blocks 4 and 4' are fitted around the stud bolt 30, protruding outward from the inner forms 2 and 2' in opposite directions, and the angles 3 and 3' are fitted around the stud bolt 30 so as to support the angle support blocks 4 and 4' . The angle support sleeves 5 and 5' and the outer forms 1 and 1' are sequentially fitted around the stud bolt 30 in opposite directions, and then the stud bolt 30 are loosely fastened with nuts 6 and 6' . Subsequently, each flat tie 22 for width matching is placed next to the form joint holes 19 formed in the lateral flanges 38 of the inner and outer forms 2 and 1, and is fixed using joint pins 7 and 7' . Then, each flat tie 21' is placed next to the form joint holes 19 of the inner and outer forms 2' and 1', and is fixed using joint pins 8 and 8' .
Afterwards, the anchoring pins 25 and 25' are inserted into the anchoring holes 27 of the outer forms 1 and 1' , and are driven into the ground 28. The nuts 6 and 6', which are loosely fastened on the opposite sides of each stud bolt 30, are firmly fastened. Thereby, the angles 3 and 3', each of which is several times as long as each form and is straight, maintains linearity between the forms, and the inner forms 2 and 2', which are lower than the outer forms 1 and 1', are raised from the ground 28 by the height of the foundation c. In this manner, after the forms are assembled, the concrete is poured into the inner cavity 29. Because the ground 28 is deep in the middle of the U-type side gutter, and because the lower portion b of each of the inner forms 2 and 2' has the curve 31 and is raised from the ground 28, the concrete is smoothly poured. After the period for curing the concrete, the nuts 6 and 6' fastened to the stud bolts 30 are unfastened, to thereby release the forms. As a result, the firmly integrated U-type side gutter is obtained.
Now, the form assembly for manufacturing a U-type side gutter according to a second embodiment of the present invention will be described below with reference to FIGS. 4 through 8.
The form assembly for manufacturing a U-type side gutter according to a second embodiment of the present invention includes an inner form 100, which is installed therein to manufacture the U-type side gutter 600 and has an outer surface having a "U" shape, and outer forms 200 and 210 installed outside the inner form 100 at a uniform interval so as to define a desired cavity 101. Meanwhile, in order to maintain the cavity 101 at a uniform interval between the inner form 100 and the outer forms 200 and 210, a plurality of flat ties 300 is installed. In order to minimize error, etc. caused by the twisting of the inner form 100 and maintain upper portions of the inner form 100 and the outer forms 200 and 210 at a uniform interval, a spacer 400 passing through the inner and outer forms 100, 200 and 210 is additionally provided to the upper portion of the inner form 100.
Hereinafter, the respective components will be described in greater detail . The inner form 100 is formed so that the outer surface thereof has a WU" shape overall. To this end, the inner form 100 includes first and second corner members 110 and 112, which are disposed on opposite sides thereof and serve as corners having a predetermined curvature, at least one horizontal expansion member 120, which is coupled between the first and second corner members 110 and 112, and first and second vertical expansion members 130 and 132, which are coupled to upper ends of the first and second corner members 110 and 112. At this time, the first and second corner members 110 and 112 can be configured in a manner in which a steel strap having a band shape for forms is cut into two types of pieces, a short one and a long one, so as to meet desired construction standards, the cut short steel strap is pressed at a lower portion thereof to form a curve 110a or 112a, the pressed and unpressed steel straps are welded to form a frame having a flange 110b or 112b along an outer circumference thereof, and a plastic plate is riveted to the frame using fastening means (not shown) such as rivets . Meanwhile, the horizontal expansion member 120 and the first and second vertical expansion members 130 and 132 can be configured in a manner in which a steel strap having a band shape for forms (standardized Euro forms or modular forms used at the construction site) is cut into two types of pieces, a short one and a long one, such that the cut long steel strap is equal to the length of each of the first and second corner members 110 and 112 of the inner form 100 and such that the cut short steel strap has a desired length, the cut short and long steel straps are welded to form a frame having a flange 120b, 130b or 132b along an outer circumference thereof, and a plastic plate is riveted to the frame using fastening means (not shown) such as rivets.
Further, the outer forms 200 and 210 are manufactured by the same process as the horizontal expansion member 120 and the first and second vertical expansion members 130 and 132, constituting the inner form 100, and are each formed to have a length equal to that of the inner form 100 and a width relatively greater than that of the inner form 100.
The flanges HOb, 112b, 120b, 130b and 132b of the first and second corner members 110 and 112, the horizontal expansion member 120, and the first and second vertical expansion members 130 and 132, all of which constitute the inner form 100, and the flanges 200b and 210b of the outer forms 200 and 210 are each provided with a plurality of pin holes HOc, 112c, 120c, 130c, 132c, 200c and 210c. Thus, in the state in which the flanges HOb, 112b, 120b, 130b and 132b of the first and second corner members 110 and 112, the horizontal expansion member 120, and the first and second vertical expansion members 130 and 132, all of which are adjacent to each other, are in surface contact with adjacent ones, and in which the flanges 200b and 210b of the outer forms 200 and 210 are in contact with adjacent ones, these adjacent components are fastened to each other using fastening means such as a pair of wedge-shaped joint pins 102 and 103. In other words, the first joint pin 102 passes through the pin hole 110c, 112c, 120c, 130c, 132c, 200c or 210c, and then the second joint pin 103 is inserted into a fastening hole 102a formed in the middle of the first joint pin 102 so as to prevent the first joint pin 102 from escaping from the pin hole 110c, 112c, 120c, 130c or 132c.
Meanwhile, the first and second vertical expansion members 130 and 132 and the outer forms 200 and 210 are provided with a plurality of flat tie through-holes 13Od, 132d, 20Od and 21Od in surfaces thereof. The first and second vertical expansion members 130 and 132 and the outer forms 200 and 210 are provided with bolt through-holes 13Oe, 132e, 20Oe and 21Oe for installing the spacer 400 at upper portions thereof.
At this time, the flat ties 300 are inserted into the flat tie through-holes 13Od, 132d, 20Od and 21Od, and maintain an interval between the first vertical expansion member 130 and the outer form 200 and between the second vertical expansion member 132 and the outer form 210. To this end, each flat tie 300 is typically used at a standardized size, such as 150 mm and 200 mm. Each flat tie 300 is provided, at opposite ends thereof, with fastening holes 300a, into which the joint pin 102 or 103 is inserted. Of course, the flat tie through-holes can be formed throughout the inner form 100, without being limited to the first and second vertical expansion members 130 and 132 and the outer forms 200 and 210.
Meanwhile, the spacer 400 includes first and second support members 410 and 420. Here, the first support member 410 has a plurality of fastening holes 412a formed at regular intervals in a first body 412 having an "L" shaped cross section, and a first bolt 414, to which a nut 416 is fastened, protruding from one end of the first body 412. Further, the second support member 420 has a plurality of fastening holes 412a formed at regular intervals in a second body 422 having an "L" shaped cross section, so as to overlap with the first body 412, and a second bolt 424, to which a nut 426 is fastened, protruding from one end of the second body 422. The first bolt 414 of the first support member 410 and the second bolt 424 of the second support member 420 are disposed in opposite directions, thus passing through the bolt through-holes 13Oe, 132e, 20Oe and 21Oe formed in the upper portion of the first and second vertical expansion members 130 and 132 and the outer forms 200 and 210. The first and second bodies 412 and 422 are in close contact with inner surfaces of the first and second vertical expansion members 130 and 132, respectively, and then the fastening holes 412a and 422a of the first and second bodies 412 and 422 are matched with each other. In this state, the first and second support members 410 and 420 are coupled by- fastening means, such as a bolt 430 and a nut 432, such that the interval adjusted between the first and second vertical expansion members 130 and 132 is maintained uniform.
Meanwhile, the first and second bolts 414 and 424 of the first and second support members 410 and 420, which pass through the bolt through-holes 13Oe, 132e, 20Oe and 21Oe of the first and second vertical expansion members 130 and 132 and the outer forms 200 and 210, have angles 440 fitted around them to secure the linearity of the inner and outer forms 100, 200 and 210, angle support blocks 450 supporting the angles 440, and interval maintenance sleeves 460 for maintaining the intervals between the first vertical expansion member 130 and the outer form 220 and between the second vertical expansion member 132 and the outer form 210 constant. Then, the first and second bolts 414 and 424 are fastened using nuts 416 and 426 at the outside of the outer forms 200 and 210.
Meanwhile, as illustrated in FIG. 9, according to a third embodiment of the present invention, one 200 of the outer forms 200 and 210 is formed higher than the other 210. A boundary block form 500 is installed between the higher outer form 200 and the first vertical expansion member 130 of the corresponding inner form 100, i.e. at the position where the angle 440 on the side of the outer form 200 is installed, so as to correspond to the height of the outer form 200. Thereby, a boundary block 550 of concrete can be integrally formed with the U-type side gutter 600.
At this time, the boundary block form 500 can be coupled to the first bolt 414, protruding from the end of the first support member 410, or can be attached to the first vertical expansion member 130 of the inner form 100. Further, a flange 500b of the boundary block form 500 is provided with pin holes 500c passing therethrough. Thus, the adjacent boundary block forms 500 are firmly maintained by the first and second joint pins 102 and 103 using the above-described method, and can be continuously expanded in a longitudinal direction.
Meanwhile, a triangular prism 560 for chamfering is additionally installed in the upper portion of the outer surface of the boundary block form 500, i.e. of a surface facing the outer form 200, so that a chamfered face 570 can be formed along an edge of the boundary block 550, formed integrally with the U-type side gutter 600, as illustrated in FIG. 10.
In this manner, it is apparent that the U-type side gutter 600 having the boundary block 550 formed integrally with the chamfered face 570 can be applied to the form assembly for manufacturing a U-type side gutter, according to the first embodiment of the present invention, illustrated in FIGS. 1, 2 and 3.
Hereinafter, processes of assembling the form assembly and manufacturing the U-type side gutter in accordance with the second and third embodiments will be described with reference to FIGS. 4 through 10.
First, fundamental pit excavation work is performed at the place where the form assembly is to be installed. Then, in consideration of the size of the U-type side gutter 600, the outer forms 200 and 210 are coupled to each other. In this case, the first joint pins 102 pass through respective pin holes 200c and 210c formed in the flanges 200b and 210b of the outer forms 200 and 210, and then each second joint pin 103 is inserted into the fastening hole 102a of each first joint pin 102. Thereby, the outer forms 200 and 210 are maintained firm, and are continuously expanded in a longitudinal direction.
Meanwhile, apart from the outer forms 200 and 210, the inner form 100 is assembled. More specifically, the inner form 100 is assembled so that the upper flanges 110b and 112b of the first and second corner members 110 and 112 are brought into contact with the lower flanges 130b and 132b of the first and second vertical expansion members 130 and 132, and so that the first and second joint pins 102 and 103 are fixedly inserted into the pin holes 110c, 112c, 130c and 132c of the first and second corner members 110 and 112 and the first and second vertical expansion members 130 and 132. The lower flanges 110b and 112b of the first and second corner members 110 and 112 are brought into contact with the opposite flanges 120b of the horizontal expansion member 120, and the first and second joint pins 102 and 103 are fixedly- inserted into the pin holes 110c, 120c, 112c and 120c of the first and second corner members 110 and 112 and the horizontal expansion member 120. Then, the inner forms 100, assembled in this way, are contacted and coupled with each other using the first and second joint pins 102 and 103, so that the inner form 100 is continuously expanded in a longitudinal direction.
At this time, reinforcing bars 610 are interconnected and fixed between the outer forms 200 and 210 and the inner form 100.
In this state, in order to maintain the intervals between the inner form 100 and the outer form 200 and the interval between the inner form 100 and the outer form 210 uniform, the flat ties 300 pass through the flat tie through- holes 13Od, 132d, 20Od and 21Od formed in the inner and outer forms 100, 200 and 210, and the joint pins 103 are inserted into the fastening holes 300a of the opposite ends of each flat tie 300. Thereby, the interval between the inner form 100 and the outer form 200 and the interval between the inner form 100 and the outer form 210 are maintained uniform. Meanwhile, the first and second bolts 414 and 424 of the first and second support members 410 and 420 constituting the spacer 400 pass through the bolt through-holes 13Oe, 132e, 20Oe and 21Oe of the first and second vertical expansion members 130 and 132 and the outer forms 200 and 210 in opposite directions.
At this time, the first and second bolts 414 and 424 of the first and second support members 410 and 420 are in close contact with and are pressed toward the inner surfaces of the first and second vertical expansion members 130 and 132, and the fastening holes 412a and 422a of the first and second bodies 412 and 422 are matched with each other. In this state, the first and second support members 410 and 420 are coupled by the bolts 430 and the nuts 432, so that the interval between the first and second vertical expansion members 130 and 132 is maintained uniform.
Meanwhile, in the process of passing the first and second bolts 414 and 424 of the first and second support members 410 and 420 through the bolt through-holes 13Oe and 132e of the first and second vertical expansion members 130 and 132, the first and second bolts 414 and 424 of the first and second support members 410 and 420 have sequentially- fitted around them the angle support blocks 450, the angles 440, and the interval maintenance sleeves 460, are passed through the bolt through-holes 20Oe and 21Oe of the outer forms 200 and 210, and then are fastened using the nuts 416 and 426 .
In this state, in which the form assembly is completely- assembled, the concrete is poured and cured for a predetermined amount of time. Then, the form assembly is disassembled in the reverse order of the assembly process, and the U-type side gutter is finished.
Meanwhile, as illustrated in FIG. 9, in order to integrally form the U-type side gutter 600 together with the boundary block 550, one 200 of the outer forms 200 and 210 is formed higher than the other 210, and the boundary block form 500 is additionally installed between the higher outer form 200 and the first vertical expansion member 130 of the corresponding inner form 100, i.e. at the position where the angle 440 on the side of the outer form 200 is installed, so as to correspond to the height of the outer form 200. Thereby, the boundary block 550, which is made of concrete, can be integrally formed with the U-type side gutter 600.
Further, the triangular prism 560 for chamfering is additionally installed at the upper portion of the outer surface of the boundary block form 500, i.e. the surface facing the outer form 200, so that the chamfered face 570 can be formed at the edge of the boundary block 550, formed integrally with the U-type side gutter 600, as illustrated in FIG. 10. At this time, the boundary block form 500 is installed so as to be easily attached or detached in various methods, such as a method by which it can be coupled to the first bolt 414 protruding from the end of the first support member 410, or so that it can be attached to the first vertical expansion member 130 of the inner form 100. In this manner, the boundary block form 500 is installed so as to be easily attached or detached by various methods. The detailed configuration and method are the same as the foregoing, and thus a detailed description thereof will be omitted.
