Description

Production system for housing for architectural structures {MANUFACTUTING SYSTEM OF HOUSING ASSEMBLY FOR BUILDING STRUCTURE}

The present invention accommodates piping equipment such as water supply/drain pipes, electric pipes, pumping facilities, and firefighting facilities built inside a building structure so that they can be opened and closed from the outside, allowing inspection and maintenance of these facilities. This relates to a production system for enclosures for architectural structures.

In modern, generalized buildings such as multi-unit buildings, it is common for assembly boxes to store exposed piping of the building to be installed in common spaces such as hallways.

In other words, the storage unit assembly to prevent exposure of piping such as pumping equipment, fire hydrant equipment, or electrical equipment when constructing a multi-story building such as a public house such as an apartment classifies the current piping by criteria such as purpose, type, and service life. It is generally adopted to improve the efficiency of standing pipe construction and to promote convenience in pipe maintenance work.

As in Korea Utility Model Notification No. 1996-0001029, the frequency of occurrence of defects in piping and the technology of manufacturing units for each purpose (sewage water, water supply, hot water supply, and heating units) and assembling units according to necessary locations to form a pipe duct;

As in Republic of Korea Patent Publication No. 1999-0037620, technology related to a pipe duct cabinet installed between the apartment door and the elevator room to install pumping equipment, fire hydrant equipment, electrical equipment, etc.;

As in Korea Utility Model Registration No. 0204645, a technology for a panel that blocks water pipes and fire hydrants next to the apartment entrance door, which is designed to be freely opened and closed with a hinge on the front door, is disclosed.

However, in such a conventional enclosure frame, the horizontal and vertical members that make up the frame use welding or bolting methods, which makes the manufacturing process complicated, increasing production costs, and creating gaps between members depending on the skill of the worker. There were problems with increased product defect rates and reduced work efficiency during assembly, installation, and disassembly for maintenance.

Accordingly, in Korean Patent Publication No. 10-2007-0028199, in the duct cabinet for installing piping facilities, as shown in FIG. 1, a bending bar or square pipe shape is provided between the fixing members fixed to the floor and ceiling of the building. The frame is erected by connecting the horizontal members and the vertical members, and assembled and installed using carbon pieces to fix the cover plate between the vertical members.

However, in this prior art, there is an advantage that the assembly of the housing frame components is somewhat easier depending on the configuration of the bullet pieces, but the stability of the bonding strength is not secured, and ultimately, multiple members are joined using a different bonding form than the conventional one. There was a problem that did not fundamentally solve the problem.

Accordingly, the present applicant has registered an enclosure frame manufactured by bending a single plate under Korean Patent No. 10-1897592. However, in the case of the above registered patent, the central part of the plate must be supported during the bending operation of the plate, but many of the various enclosure frame types have a transverse member placed in the center, so the central support may not be secured, so it may not be applicable. There was a problem in that the size of the bending equipment increased due to the large change in the height of the member depending on the bending stage. Additionally, the entire process included the punching process twice in the order of punching-bending-punching-bending, which resulted in the manufacturing process being somewhat longer. there was.

Meanwhile, the storage space formed in the enclosure frame 100 includes a door 200 that selectively opens and closes the storage space, as shown in FIGS. 2 and 3.

The door 200 is provided in plural numbers (200A, 200B) depending on the number of storage spaces. Basically, it is rotatably provided on one side of the storage space of the enclosure frame 100, and is equipped with a lock handle and indicator for locking. Incisions 210A and 210B may be formed through which instruments, buttons, etc. can be exposed to the outside and combined with each other.

As shown in Figure 6, the doors (200A, 200B) are formed in a rectangular shape with plates bent to match the size and shape of the storage space, specifically the door front plate, door side plates (240A, 240B), It is composed of a door upper side plate (220A, 220B) and a door lower side plate (230A, 230B).

And on one side of the door upper side plates (220A, 220B) and the door lower side plates (230A, 230B), pin coupling holes (250A, 250B) are provided for rotatably coupling the door (200A, 200B) to the enclosure frame 100. This is formed.

Next, let's look at the combined structure of the door and the enclosure frame.

The enclosure for an architectural structure is a structure embedded in the concrete wall of the building structure. The enclosure frame 100 is vulnerable to corrosion due to water leakage or foreign substances, and a decrease in the bonding strength of the joints, but there is a risk of shape deformation unless a strong external force is transmitted. On the other hand, in the case of the door 200, deformation of the shape of the door due to frequent opening and closing is a problem. In particular, recently, as the frequency of opening and closing the door 200 has rapidly increased compared to its original purpose, such as when parcel delivery items are delivered to the free space inside the box, defects due to deformation of the door 200 are frequently occurring.

On the other hand, if the door 200 is damaged, it is very difficult to separate the enclosure frame 100 itself from the wall (sometimes impossible depending on the installation method), so when the enclosure frame 100 is fixed, , the door 200 must be separated and replaced with a new door 200. However, when using a general hinge-type hinch, it is not easy to place work tools such as a screwdriver inside the housing frame to work, causing damage to the door. There is a problem in that the separation and fastening process is difficult.

Accordingly, the present invention proposes a door coupling structure that can easily attach and detach the door of an enclosure for an architectural structure, and this will be described in detail below.

As shown in Figure 7a, the present invention is basically a door ( 200A).

And in the case of the additional door (200B), both upper and lower pin coupling holes (250B) are supported by gravity pins (340).

Specifically, the elastic pin 320 is a pin formed with a bent gripping portion 323 on one side and an extension portion 321 with an enlarged cross-section on the other side, and is attached to the bracket 310A fixed to the housing frame 100. ), the gripping part 323 is located on the upper side of the bracket 310A, and the expansion part 321 is supported in close contact with the upper surface of the upper edge inner plate 34 downward.

Accordingly, the lower end of the elastic pin 320 below the expansion portion 321 penetrates the upper edge inner plate 34 and penetrates the pin coupling hole 250A, thereby penetrating the upper pin coupling hole of the door 200A. (250A) is rotatably supported.

At this time, preferably, between the bracket (310A) and the extension part 321, there is an elastic member that provides an elastic force to adhere the extension part 321 to the upper border inner plate 34 with respect to the bracket (310A). (330) may be provided.

Meanwhile, the gravity pin 340 is a pin with an expanded surface 341 formed in the middle portion, and the length of the pin and the position of the expanded surface 341 can be formed in various ways depending on the installation location.

The gravity pin 340 is configured to penetrate and support the remaining pin coupling hole(s) of the door excluding the pin coupling hole supported by the elastic pin 320, as shown in FIG. 7A. The lower pin coupling hole 250A of the door 200A is supported by the upper end of the gravity pin 340, and the expanded surface 341 of the gravity pin 340 is supported on the upper surface of the upper middle border plate 52. The lower part of the gravity pin 340 of the expanded surface 341 penetrates the middle border upper plate 52 and the middle border lower plate 54, and the upper pin coupling hole 250B of the lower door 200B ) is supported through the

Meanwhile, the lower pin coupling hole 250B of the lower door 200B is supported by another gravity pin 340, and the expanded surface 341 of the gravity pin 340 is the lower border inner plate 44. ) is supported on the upper surface, and the upper end of the gravity pin 340 on the expanded surface 341 penetrates the lower pin coupling hole 250B of the door 200B. And the lower end of the gravity pin 340 below the expanded surface 341 penetrates the lower border inner plate 44.

Of course, the gravity pin 340 or the elastic pin 320 penetrates the upper border inner plate 34, lower border inner plate 44, middle border upper plate 52, and middle border lower plate 54, respectively. A through hole is formed to

In the case of the embodiment shown in FIG. 7A, looking at the door separation process, the user opens the door and lifts the grip portion 323 upward.

Accordingly, the upper pin coupling hole 250A of the door 200A is disengaged, and the door 200A is twisted and separated upward. At this time, in order for the door (200A) to be separated within the gap between the door (200A) and the enclosure frame (100), the gravity pin (340) extends through the pin coupling hole (250A) of the door (200A). The length should be relatively short.

Thereafter, when the gravity pin 340 exposed inside the storage space is pulled out and removed, the engagement of the upper pin coupling hole 250B of the lower door 200B is released, and the door 200B is sequentially moved from the top to the bottom in the same manner. It can be easily separated.

Meanwhile, after replacing/repairing the door 200, the joining process is performed in the reverse order of the separation process.

According to this, in the present invention, the separation/assembly process of the doors 200A and 200B can be easily performed without separate tools.

Figure 7b shows an embodiment in which the elastic pin 320 is installed on the back of the door 200A. In the embodiment shown here, the basic coupling principle is the same as described above, but the bracket 310B is installed on the back of the door 200A. It is fixed to, and the extension part 321 is supported on the lower surface of the door upper side plate 220A, and the elastic member 330 brings the extended part 321 into close contact with the lower surface of the door upper side plate 220A.

In this embodiment, when the door 200 is separated, the gripping part 323 of the elastic pin 320 is located in the open door 200, so the gripping part 323 is held and lowered downward. The process is easier compared to the embodiment shown in FIG. 7A.

However, in this case, since the elastic pin 320 penetrates the bracket 310B fixed to the door 200A, the through-hole position of the bracket 310B is precisely located at the center of rotation of the door, requiring precision in manufacturing. demands.

Meanwhile, as shown in FIG. 8, the door may be coupled to the enclosure frame through a clip band-type bracket 350 and a clip band-type elastic pin 360.

At this time, the clip band-type bracket 350 includes an inner support plate 351, a folding support plate 352, a bracket support plate 355, a first protruding bracket 357, and a second protruding bracket 359. , It simultaneously performs the role of fixing the folded state of the inner plate 24 and the folding plate 37 of the enclosure frame and supporting the elastic pin 360.

Specifically, the inner support plate 351 and the folding support plate 352 are formed in a 'U' shape, and are fitted so that the folded inner plates 14 and 24 and the folding plates 36 and 37 are arranged inside. .

At this time, the left and right division may vary depending on the opening direction of the door.

And the separation distance between the inner support plate 351 and the folded support plate 352 is formed to be equal to or smaller than the sum of the thicknesses of the inner plates 14 and 24 and the folded plates 36 and 37, so that the inner support plate 351 And it is preferable that the inner plates 14, 24 and the folding plates 36, 37 are tightly fixed by inserting the folding support plate 352.

Meanwhile, a folding fixing hole 353 is formed in the inner support plate 351 and the folding support plate 352, and the clip band type bracket 350 is secured by a bolt/nut fastened through the folding fixing hole 353. ), the folded state of the inner support plate 351 and the folded support plate 352 can be stably maintained.

And the bracket support plate 355 extends in the vertical direction from the end of the folded support plate 352, and is a part for forming protruding brackets 357 and 359 through which the clip band-type elastic pin 360 passes. .

Additionally, as shown in FIG. 8, a first protruding bracket 357 extending toward the folding support plate 352 is formed at the upper end of the bracket support plate 355.

The first protruding bracket 357 is a configuration corresponding to the bracket 310A of the embodiment shown in FIG. 7A, and the clip band-type elastic pin 360 penetrates the upper part of the clip band-type elastic pin 360. Play a supporting role.

Meanwhile, the clip band-type elastic pin 360 penetrates below the first protruding bracket 357, and a second protruding bracket 359 supporting the lower part of the clip band-type elastic pin 360 is formed. It may be possible.

That is, when the clip band-type elastic pin 360 is raised upward, if the lower end of the clip band-type elastic pin 360 leaves the upper border inner plate 34, the clip band-type elastic pin 360 It is not maintained vertically and is tilted, making it difficult to find the correct position when reconnected, and in some cases, the clip band-type elastic pin 360 may be separated.

In order to prevent this, the second protruding bracket 359 is formed to be spaced apart from the upper border inner plate 34 by a predetermined height, through which the lower end of the clip band-type elastic pin 360 is connected to the upper border inner plate 34. Even when the door 200 is separated by leaving (34), the clip band-type elastic pin 360 is supported by the first protruding bracket 357 and the second protruding bracket 359, respectively, and is stably maintained. The vertical shape can be maintained.

Meanwhile, as shown in FIG. 8, the clip band-type elastic pin 360 is a pin in which a bent gripping portion 363 is formed on one side and an extension portion 362 with an expanded cross-section is formed on the other side, Penetrating through the first protruding bracket 357 and the second protruding bracket 359, the gripping part 323 is located above the first protruding bracket 357, and is located on the upper surface of the second protruding bracket 359. The expanded portion 362 is supported in close contact.

At this time, the elastic member 330 is supported on the upper surface of the extension part 362 and the lower surface of the first protruding bracket 357, thereby bringing the extension part 362 into close contact with the upper surface of the second protruding bracket 359.

Meanwhile, a locking protrusion 365 is formed at the lower part of the gripping part 363 of the clip band-type elastic pin 360 and protrudes in the same direction as the gripping part 363, and the first vertical through hole 356 is formed. It includes a circular part and an extension part extending from the circular part in a direction opposite to the bracket support plate 355.

Accordingly, when the direction of the extension of the joint protrusion 365 and the first vertical through hole 356 coincides, the clip band-type elastic pin 360 can be moved up and down, while the joint protrusion If the direction of the extension of 365 and the first vertical through hole 356 is different, the clip band-type elastic pin 360 becomes impossible to move up and down.

Therefore, when dismantling the door, the user rotates the gripping part 363 to match the direction of the joint protrusion 365 and the extension of the first vertical through hole 356, and then pins the clip band-type elastic pin. Lift (360) upward to release the binding of the upper part of the door by the lower end of the clip band-type elastic pin (360).

Thereafter, the user rotates the gripping part 363 to maintain the clip band-type elastic pin 360 moving in the direction and perform the door separation operation without separately pressing the gripping part 363. It can be performed easily.

And after the replacement or repair of the door 200 is completed, the gripping part 363 is rotated again to match the direction of the joint protrusion 365 and the extension of the first vertical through hole 356, The clip band-type elastic pin 360 can be moved downward and bound to the upper part of the door without correcting the direction of the clip band-type elastic pin 360 in the vertical direction.

Hereinafter, we will look at the manufacturing method of the housing for building structures as described above.

Figure 9 is a flow chart showing an example of the manufacturing process of the housing for building structures according to the present invention, Figure 10 is an exemplary diagram showing changes in cross-sectional shape according to the manufacturing process of the housing for building structures according to the present invention, and Figure 11 is an illustrative diagram showing another example of a change in shape according to the manufacturing process of the housing for an architectural structure according to the present invention. Meanwhile, in Figure 5, in order to easily understand the manufacturing sequence of the housing for building structures according to the present invention, the bending position difference on the manufacturing base material (plate material) is displayed according to the process sequence.

Prior to the detailed description, the manufacturing sequence of the housing for a building structure according to the present invention may be performed in various ways. However, since differences in constructability occur depending on the manufacturing order, the following will look at representative manufacturing methods with desirable manufacturing ease.

Hereinafter, the manufacturing process of the enclosure frame according to the present invention will be described. In this regard, Figure 5 is a development diagram for explaining the manufacturing process of the enclosure frame.

Referring to Figure 5, the boundaries of the side border inner plates (14, 24) and the folding plates (36, 37, 46, 47, 56, 57) and the side border inner plates (14, 24) and the side border front plate (13) , 23) is the boundary line of the first bent portion (C1), the side border front plate (13, 23) and the side border outer plate (12, 22), and the side border outer plate (12, 22) and the outer support plate (11). , 21), the boundary line of the second bent portion (D1), the upper border front plate 33 and the upper folding plates 36, 37, and the lower border front plate 43 and the lower folding plates 46, 47. The boundary lines each form a third bent portion G1.

Here, the part shown with a dotted line among each boundary line shows the part where the fold is folded in the direction in which the fold protrudes forward (hereinafter referred to as 'square fold'), and the part shown with a dashed line shows the part where the fold is folded towards the back side. It shows the part that is folded in the protruding direction (hereinafter referred to as 'reverse folding').

It is desirable to secure productivity by producing the enclosure frame according to the present invention using an automated machine tool (CNC, etc.). To this end, the enclosure frame is produced through the following process.

First, as shown in Figure 9, the central portion (A), which forms the internal receiving space of the enclosure frame after being folded from a single sheet, is removed by punching, and the outer portion (B) is cut to cut the sheet ( S110).

And a cutting process of the incision line (H) consisting of the boundary line between the upper folding plates (36, 37), the middle folding plates (56, 57), the lower folding plates (46, 47), and the side edge inner support plates (14, 24). (S12) is performed, and the cutting process may be performed simultaneously with the punching and cutting processes of step 110.

Subsequently, in the sheet cut as described above, the first bent part (C1) (S130), the second bent part (D1) (S140), and the third bent part (G1) (S150) are sequentially bent, One side is folded by folding the folding line (F1) consisting of the boundary line between the side border inner plates (14, 24) and the folding plates (36, 37, 46, 47, 56, 57) and bringing the side border inner plates and the folding plate together. forms a border.

Specifically, the first bent portion (C1) and the second bent portion (D1) are performed by two-stage bending by bending two bend lines at once. For this purpose, a mold with a two-stage bending surface is used in the process. This is carried out, and this will be explained in more detail later.

In addition, the two bending lines of the first bent part C1 and the second bent part D1 and the one bending line of the third bent part G1 refer to bending in a right angle direction.

Meanwhile, if the steps 160 and 170 are described in detail, in a state where the first to third bent portions (C1) to (D1) are formed, the bending line of one of the first bent portions (C1) is A hamming process is performed to bring the folding line (F1) into closer contact with the right angle and fold it at an acute angle (S160).

In this process, the inner support plate 25 or 15 is hammed and deployed close to horizontal with the floor surface.

Thereafter, through the folding machine, the folding plate (36, 46 or 37, 47) and the inner edge plate (14 or 24) are completely brought into close contact with the folding line (F1) (S170).

Next, steps 130 to 170 are repeatedly performed on the other side to form a side border on the other side (S200).

When the side borders (10, 20) are formed through a bending process as described above, a transverse bent portion (E11) is subsequently formed to form the upper border (30), lower border (40), and middle border (50) (if necessary). ~E16) are sequentially formed through a bending process (S300).

At this time, the bending process of step 300 is also performed by two-stage bending by bending two bend lines at once, and the mold with a two-stage bending surface for performing this will be described in detail again.

Meanwhile, according to the present invention, the bending process of the first bent portion (C1), the second bent portion (C2), and the transverse bent portions (E11 to E16) is performed using a forming mold having a two-stage bending surface. This is a characteristic of the invention.

That is, the first bent portion C1 in the 130th step is formed by a single press process using a mold 400 with a two-stage bent surface. ' and the second bent portion (D1) of the 140th step is formed by a single press process using a mold 400 with a two-stage bending surface. ' It is bent into a shape.

In this way, according to the present invention, by bending in a single press process using a mold formed with a two-stage bending surface, the conventional two bending processes can be reduced to one.

To this end, the forming mold 400 according to the present invention may be configured to include an upper mold 410, a middle mold 420, and a lower mold 430, as shown in FIG. 14. At this time, a first two-step curved surface is formed between the upper mold bottom surface 411 and the middle mold top surface 421, and a second two-step curved surface is formed between the middle mold bottom surface 422 and the lower mold top surface 431. A single curved surface may be formed.

Here, the first two-step bending surface is rotated clockwise. ' is formed in the shape, and the second two-stage bending surface is rotated counterclockwise. ' It can be formed in the form.

Accordingly, according to the present invention, the shape of the forming mold 400 for two-stage bending is implemented in a form that minimizes stress by forming a bending surface in an oblique direction rather than a perpendicular direction, thereby preventing accidents in which the member is damaged during bending work. can be prevented.

In addition, according to the present invention, by forming the two-stage bending surface at an angle in the diagonal direction as described above, the work space is minimized as the bent member after molding is disposed in the 45° direction of the mold. In addition, the vertical movement distance between the upper and lower molds for bending can be minimized, thereby reducing the installation space of the equipment.

In addition, as the bending inclined surface of the two-stage bending mold is arranged in the inclined direction, a distance for the plates on both sides to be retracted as much as possible is secured when the press is lowered, thereby preventing damage to the member. That is, in the present invention, the shape of the forming mold for two-stage bending is implemented in a form that minimizes stress by forming a bending surface in an inclined direction rather than a right angle direction, thereby preventing accidents in which the member is damaged during bending work. .

Meanwhile, in the present invention, contrary to the above-mentioned molding mold, the molding mold has a first two-step curved surface rotated counterclockwise. ' is formed in the shape, and the second two-stage bending surface is rotated clockwise. ' It can also be formed in the form.

In this case, the first bent portion C1 is bent on the second two-step bending surface, and then the second bent portion D1 is bent on the first two-step bending surface. At this time, the second bending line D1 may be bent at the second two-stage bending surface. In this case, the upper and lower surfaces of the plate are turned over and the bending process is performed.

In addition, the transverse bent portions (E11 to E16) of the 300th step are also formed using a two-stage bending mold as described above.

Meanwhile, the present invention may be performed by another process sequence.

That is, after step 120, step 150 of processing the third bending line (G1) of the side part is first performed, and then sequentially the first bending line (C1) of step 130 and the second bending line of step 140. (D1) can be processed.

If the construction sequence shown in FIG. 9 is referred to as the first embodiment, and processing the third bending line (G1) of the side portion first is referred to as the second embodiment, the process of forming the side portion of the housing for a building structure according to these process sequences is shown in FIG. 10 You can check it through .

As shown in Figure 10, the number of processes is the same for both embodiments, but looking at the shape of the member in the middle of the processing process, in the case of the first embodiment, compared to the second embodiment, the member protrudes in the right angle direction (vertical direction). You can see that the height is low.

In particular, it can be confirmed that the downward vertical protrusion length of the member is very long in the 150th and 130th steps of the second embodiment.

In this case, not only does it become difficult to move the member using a robot arm or transfer it through a conveyor in each processing process, but also when placing the member between molds for the bending process, the lifting and lowering height of the mold must be increased. Therefore, there is a disadvantage that the size of the machine tool itself increases.

Meanwhile, Figure 11 shows the process of actually processing the housing frame of a single door to help understand the hamming process (S160) and folding process (S170) described above.

However, since the process sequence shown in FIG. 11 is different from the first and second embodiments shown in FIG. 10, it will be examined with reference to this.

That is, in the case of the embodiment shown in FIG. 11, after processing the first and third bending lines of the side portion, performing the hamming process and folding process, and processing the transverse bending portion, the second bending line is formed. It proceeds in the order of processing.

Specifically, as shown in FIG. 11, a member with the first bending line and the third bending line formed is shown in FIG. 11(a).

Afterwards, through the forming machine, the folding line F1 is brought into close contact at an acute angle to form a hammed plate, as shown in FIG. 11(b).

And, the folding plate (36, 46 or 37, 47) and the inner border plate (14 or 24) are completely brought into close contact with each other through the folding machine, as shown in FIG. 11(c).

At this time, it can be confirmed that the inner support plate 25 or 15 is hammed and developed close to horizontal with the floor surface.

And Figure 11(d) shows the transverse bent part being formed by folding, and Figure 11(e) shows the second folding part being formed.

Meanwhile, when the manufacturing of the housing frame is completed through the above-described process, the individually manufactured doors are fastened to the housing frame using gravity pins and elastic pins to complete the manufacturing of the housing for the architectural structure.

Specifically, when the housing frame is completed, a bracket into which an elastic pin with an elastic member is inserted is fastened to the inside of the housing frame or the inside of the door to fix the elastic pin.

Of course, in this case, the clip band type bracket 350 to which the clip band type elastic pin 360 is fastened can be fastened to the enclosure frame 100.

Afterwards, when there are multiple doors 200 coupled to the enclosure frame 100, the lower door 200B is coupled using the gravity pin 340, and the uppermost door 200A is connected to the lower pin coupling hole. After inserting (250A) into the gravity pin 340, the elastic pin 320 is pulled out to the outside of the bracket 310A and placed in the coupling position, and the elastic pin 320 is placed to couple the door 200. Complete .

Meanwhile, in the method of manufacturing an enclosure for a building structure according to the present invention as described above, the order of each process is related to the configuration of the manufacturing equipment.

Therefore, hereinafter, the manufacturing system for manufacturing the housing for building structures according to the present invention will be described in detail.

Figure 12 is an exemplary diagram showing an example of the configuration of a building enclosure manufacturing equipment according to the present invention, Figure 13 is an exemplary diagram showing another example of a building enclosure manufacturing equipment according to the present invention, and Figure 14 is an exemplary diagram showing a configuration example of a building enclosure manufacturing equipment according to the present invention. It is an exemplary diagram showing a cross section of a two-stage bending mold used in a two-stage bending machine constituting a building enclosure manufacturing facility according to the present invention, and Figure 15 is an exemplary diagram showing a folding machine constituting the building enclosure manufacturing facility according to the present invention. , FIG. 16 is an exemplary diagram showing the configuration of a lower mold used in a folding machine that constitutes a building enclosure manufacturing facility according to the present invention.

First, referring to Figure 12, looking at the overall configuration of the manufacturing system according to the present invention, the housing for building structures according to the present invention includes a single-stage bending machine, a two-stage bending machine, a forming machine (FMM), and a folding machine (FLM). It is composed by:

At this time, in the case of a two-stage bender, the length of the bent part is different from each other and has a folded three-dimensional border shape, so a longitudinal two-stage bender (LBM2) to bend the side part in the longitudinal direction of the member and a longitudinal two-stage bender (LBM2) to bend the side part in the longitudinal direction of the member It is classified into a transverse two-stage bending machine (TBM) for bending.

Specifically, the housing manufacturing system for building structures according to the present invention shown in Figure 12 includes a longitudinal two-stage bending machine (LBM2), a longitudinal single-stage bending machine (LBM1), a forming machine (FMM), and a folding machine (FLM). ), a transverse double bending machine (TBM), a robot arm (R), and a transfer conveyor (CV).

At this time, there are 4 longitudinal two-stage bending machines (LBM2), 2 longitudinal single-stage bending machines (LBM1), 2 forming machines (FMM), 2 folding machines (FLM), and transverse two-stage bending machines (TBM). ) It consists of N pieces, including a robot arm (R) and a transfer conveyor (CV).

And N is a number determined depending on the type of enclosure for the building structure being manufactured. Specifically, N is defined as the number of transverse members of the enclosure × 2, and N = (number of storage spaces + 1) * 2. It can be.

That is, as shown in Figure 12, each facility is installed along the transfer conveyor (CV) for each process, with two longitudinal two-stage bending machines (TBM) and a longitudinal single-stage bending machine on one side of the transport conveyor (CV). One (LBM1), one forming machine (FMM), one folding machine (FLM), and N/2 transverse double bending machines (TBM) are installed, and the same equipment is installed on the other side of the transfer conveyor (CV).

Accordingly, by allowing the production process shown in FIG. 9 to be performed at each stage with one equipment, process delay time can be minimized and a high production speed can be achieved.

In other words, the equipment configuration of the housing manufacturing system for building structures must be optimally designed taking into account the production speed compared to the equipment configuration cost.

At this time, the moving speed of the transfer conveyor (CV) is adjusted to the work time of the unit process with the longest unit work time, and in other unit processes, a corresponding waiting time (process delay time) is generated, so as in the present invention, The production speed of a manufacturing system in which each process is executed sequentially and step by step is maximized when the unit process time in each facility is configured to be the same, as no delay occurs in each facility.

Specifically, the working time of the longitudinal two-stage bending machine (LBM2), longitudinal single-stage bending machine (LBM1), forming machine (FMM), folding machine (FLM), and transverse two-stage bending machine (TBM) that constitute the present invention. In contrast, in the case of a bending machine, the work is performed by moving the work object in the horizontal direction and then pressing it once, so the work time is almost the same.

A folding machine not only transports the work object in the horizontal/vertical direction and then again in the vertical/horizontal direction after pressing, but the pressing process is also performed by the relative movement of the mold, so the work time is relatively shorter than that of the bending machine. This takes a long time.

Meanwhile, in the case of a forming machine, not only does the pressure roller simply press and rotate to hammer the work object, but it does not require processing precision, so the work time is relatively short.

Accordingly, in the equipment configuration shown in FIG. 12, the maximum unit process time occurs in the folding process, and the production speed of the case is determined by the unit process time of the folding process. This type of equipment configuration has a great effect in improving production speed, but it has the disadvantage of increasing the number of equipment, increasing the cost of equipment preparation, and increasing the area of the factory where the equipment will be installed, increasing equipment investment costs.

Accordingly, in the present invention, as described above with reference to FIG. 14, a two-stage bending mold is applied to a two-stage bending machine and the equipment is configured as shown in Figure 13, thereby simplifying the equipment and reducing the production speed of the case. It can be maintained.

The embodiment shown in Figure 13 includes two longitudinal two-stage bending machines (LBM2) employing a two-stage bending mold, one longitudinal single-stage bending machine (LBM1), one forming machine (FMM), and a folding machine ( It consists of N/2 transverse two-stage bending machines (TBM) equipped with one-stage FLM and two-stage bending molds.

In this embodiment, the first longitudinal two-stage bending machine (TBM) adopts a two-stage bending mold, so that the work object is placed between the upper mold 410 and the middle mold 420 through the first bending portion C1. processing, and the second bent portion D1 is processed between the lower mold 430 and the middle mold 420.

Thereafter, the first bent portion C1 and the second bent portion D1 on the other side are processed in the same manner through a second longitudinal two-stage bending machine (TBM).

That is, the longitudinal two-stage bending machine (LBM2) processes both the first bent portion and the second bent portion on one side of the enclosure frame 100. At this time, the unit process time consists of two pressings and moving the member between them. /Defined as the rotation time.

Meanwhile, the longitudinal single-stage bending machine (LBM1) processes the third bending portion (G1) on the left and right sides of the housing frame, respectively. In this case as well, the unit process time is defined as two pressings and the time to move/rotate the member between them.

Afterwards, the forming machine (FMM) performs bending on the folded portions on both left and right sides of the housing frame. In this case, the unit process time is defined as the time to bend twice and move/rotate the member, which takes approximately the same or slightly shorter time as the unit process time due to the transverse two-stage bending machine (TBM).

Meanwhile, the folding machine performs the folding process of the folded portions on the left and right sides of the case frame through two folding processes. At this time, the unit process time is defined by two folding pressings and the horizontal/vertical/rotation time of the work object. In this embodiment, the unit process time is formed shorter than the unit process time by a longitudinal two-stage bending machine, The difference is not large.

And each of the transverse two-stage bending machines (TBM) sequentially bends two transverse bends (E11 and E12) from one side of the housing frame. In the case of the embodiment in which two storage spaces are formed (N = 6 ), the three transverse two-stage bending machines (TBM) each produce transverse bends (E11, E12), transverse bends (E13, E14), and transverse bends (E15, E16) from one side of the enclosure frame. bend each.

At this time, the unit fixing time of each transverse two-stage bending machine (TBM) takes the same as the unit process time of the longitudinal two-stage bending machine (LBM2).

That is, in the case of the embodiment shown in FIG. 13, compared to the embodiment shown in FIG. 12, the equipment is simplified to 1/2, thereby significantly reducing the equipment cost, but the unit process time is the same, so the production speed of the enclosure is the same. It can be maintained.

On the other hand, although not shown, in the case of a box for a gable structure with an odd number of storage spaces (1, 3,...), a longitudinal single-stage bending machine (LBM1) and a forming machine (FMM) are used. By using a unit process, the equipment can be configured more simply while maintaining production efficiency.

As an example, there is one storage space. In this case, one longitudinal two-stage bending machine (LBM2) with a two-stage bending mold, one longitudinal single-stage bending machine (LBM1), and a forming machine (FMM) ), one folding machine (FLM), and N/4 units (1 unit) of a transverse two-stage bending machine (TBM) equipped with a two-stage bending mold.

In this embodiment, since the longitudinal two-stage bending machine (TBM) adopts a two-stage bending mold, the work object is processed through the first bent portion C1 between the upper mold 410 and the middle mold 420. , the second bent portion D1 is processed between the lower mold 430 and the middle mold 420.

Thereafter, the work object is rotated, and the first bent portion C1 and the second bent portion D1 on the other side are processed in the same manner.

That is, the longitudinal two-stage bending machine (LBM2) processes both the first and second bent parts on the left and right sides of the enclosure frame 100. At this time, the unit process time is four pressings and moving the member between them. /Defined as the rotation time.

Meanwhile, the longitudinal single-stage bending machine (LBM1) and forming machine (FMM) operate in one unit process, where the robot arm (R) places the work object on the longitudinal single-stage bending machine (LBM1), and the third The bent portion (G1) is processed and moved to a forming machine (FMM) to perform bending on the folded portion.

Thereafter, the robot arm (R) rotates the work object to perform the third bent portion (G1) processing and forming process on the other side of the housing frame.

In this case, the unit process time is defined as two pressings, two bendings, and the time to move/rotate the member between them, and it takes almost the same time as the unit process time by the transverse two-stage bending machine (TBM). .

Meanwhile, the folding machine performs the folding process of the folded portions on the left and right sides of the case frame through two folding processes. At this time, the unit process time is defined by two folding pressings and the horizontal/vertical/rotation time of the work object. In the case of this embodiment, the unit process time is formed shorter than the unit process time by a transverse two-stage bending machine, The difference is not large.

And the transverse two-stage bending machine (TBM) sequentially bends four transverse bends (E11, E12, E13, E14) from one side of the enclosure frame, and at this time, the unit fixing time is the same as that of the longitudinal two-stage bending machine. (TBM) takes the same amount of time as the unit process time.

That is, in this case, compared to the embodiment shown in FIG. 12, the equipment is simplified to 1/4 for the longitudinal two-stage bending machine (LBM2) and 1/2 for other equipment, while significantly reducing equipment costs. By designing 4 bending processes with a short single operation time and 2 folding processes with a long single operation time as a unit process, the reduction in production speed has the effect of being very small.

Meanwhile, looking at the bending machine applied to the present invention, Figure 15 shows a folding machine (FLM) constituting the building enclosure manufacturing equipment according to the present invention, and Figure 16 shows the lower mold 530 used for this. It is done.

As shown in FIG. 15, the folding machine (FLM) includes a stand 510, a lower mold 530, an upper mold 550, and a press 540.

The pedestal 510 is a part on which the lower mold 530 is seated, and has an inclined support surface 520 inclined on both sides, and a separation prevention protrusion 521 that prevents the lower mold 530 from leaving the inclined support surface 520. ) is formed

Meanwhile, the lower mold 530 is a part where the work object is placed, and is divided into an outer mold 531 and an inner mold 533 around a space in the center.

At this time, the lower portions of the outer mold 531 and the inner mold 533 are formed as inclined surfaces corresponding to the inclined support surfaces 520 on both sides of the pedestal 510, and when moving downward, the outer mold 531 and the inner mold 533 ) is configured to narrow the space between them.

In addition, an elastic body is provided in the space between the outer mold 531 and the inner mold 533, and when the lower mold 530 is not pressed, the outer mold 531 and the inner mold 533 are moved by elastic force. ) are placed spaced apart.

In addition, a step portion corresponding to the departure prevention projection 521 is formed on the inclined surface of the lower portion of the outer mold 531 and the inner mold 533, and by combining the departure prevention projection and the step portion, the outer mold and the inner mold are formed. The elastic force of the elastic body prevents it from moving upward.

Meanwhile, the press 540 has the upper mold 550 coupled to its lower part, moves in the vertical direction, and serves to press the lower mold 530 downward through the upper mold 550.

Looking at the folding process of such a folding machine (FLM), first, the enclosure frame 100 is transferred and placed on the upper surface of the lower mold 530, and the space between the outer mold 531 and the inner mold 533 is formed. The folded portion F1 of the enclosure frame 100 is seated in the position.

At this time, a left or right border front plate 13, 23 is located on the upper surface of the outer mold 531, and an upper, middle, or lower border front plate 33, 43, 53 is located on the upper surface of the inner mold 533. , Bent edge inner plates 12 and 24 and folding plates 36, 56, 46, 37, 57 and 47 are located in the space between the outer mold 531 and the inner mold 533.

Therefore, it is preferable that the width of the outer mold 531 is shorter than the width of the edge front plates 13 and 23, and the width of the inner mold 533 is the width of the edge front plates 33, 43, and 53. It is preferable to be shorter or equally formed.

Thereafter, when the press 540 descends and pressurizes the lower mold 530, the outer mold 531 and the inner mold 533 move downward and the separation space decreases, and the inner edge plate 12 , 24) and the folding plates (36, 56, 46, 37, 57, 47) are folded together.

At this time, the hammed inner support plates 15, 25 are located on the separation space. As the separation space is reduced, there is a risk that the hammed inner support plates 15, 25 may be spread or crushed.

Accordingly, as shown in FIG. 16, the lower mold 530 according to the present invention has an inner support plate insertion groove 535 recessed inward on the vertical surface of the spaced space of the inner mold 533. Accordingly, during the folding process, the edge inner support plates 15 and 25 are inserted into the inner support plate insertion groove 535 to prevent damage.

Meanwhile, upper, middle, or lower border front plates 33, 43, and 53 are located on the upper surface of the inner mold 533, but not all members are seated over the entire length of the inner mold 533, and the storage space is Since the member is punched out and empty in the formed part, the member is not seated in that part.

Accordingly, when the press 540 is pressed, the load is not evenly distributed throughout the outer mold 531 and the inner mold 533, and there is a risk of slight errors occurring between the folded surfaces.

To prevent this, an error compensation protruding surface 537 is formed on the upper surface of the inner mold 533 according to the present invention, protruding with a preset thickness t.

That is, the punching area of the storage space of the enclosure frame 100, which is the work target, is arranged to be inserted into the error compensation protruding surface 537.

At this time, the thickness (t) of the error compensation protrusion surface 537 is equal to the thickness of the member of the work object enclosure so that the height of the error compensation protrusion surface 537 is the same as the upper surface of the inner mold 533 on which the member is seated. It is set to thickness.

Meanwhile, as shown in FIG. 16, the outer mold 531 and the inner mold 533 may be divided into multiple pieces along the longitudinal direction, which facilitates assembly/disassembly/replacement of the lower mold 530. This is to facilitate the replacement of the lower mold 530 when the specifications (plate thickness, etc.) of the housing to be worked on change.

The rights of the present invention are not limited to the embodiments described above but are defined by the claims, and those skilled in the art can make various changes and modifications within the scope of the claims. This is self-evident.

The present invention accommodates piping equipment such as water supply/drain pipes, electric pipes, pumping facilities, and firefighting facilities built inside a building structure so that they can be opened and closed from the outside, allowing inspection and maintenance of these facilities. Pertaining to manufacturing equipment for enclosures, according to the present invention, the punching, cutting, bending and folding processes are performed with a single sheet of plate through automated equipment, and the enclosure frame is manufactured through an automated production process. It has the effect of providing a production system for enclosures for architectural structures that minimizes speed and manufacturing errors.
