Description

Foam panel assembly for synthetic resin formwork {PLASTIC FORM ASSEMBLY FOR CONSTRUCTION}

The present invention relates to a foam panel assembly for synthetic resin formwork,

More specifically, it replaces the existing formwork such as Euroform, which is composed of laminated wood panels such as veneer plywood and metal rim, is lightweight and can be recycled and reused semi-permanently without generating waste. It relates to a foam panel assembly for a synthetic resin formwork that can be mass-produced.

In recent years, as shown in FIG. 1, Euroform composed of laminated wood panels such as veneer plywood and a lattice structure metal frame as shown in FIG. In construction, gang form is sometimes used because it enables faster and more systematic construction.

However, Euroform is unsuitable for repeated use and must eventually be disposed of as construction waste. As wood is used, it also acts as a factor causing forest damage, which is a reality that requires the development of alternative products using synthetic resin.

As a technology related to the conventional synthetic resin formwork, there is Utility Model Registration No. 20-0394606 (registration date August 26, 2005) [Plastic plate for concrete form that combines strength and light weight],

In the registered design, one side of the aluminum frame is placed on one side of a thin, lightweight plastic plate for a plywood stand, and the other side is formed with longitudinal and transverse ribs that intersect each other to reinforce the strength, but the edge to correspond to the aluminum frame. By lowering the height of the longitudinal and transverse ribs of the long and short side frames, several longitudinal mid-sections, and the part in contact with the transverse mid-section, the plastic plate can be easily attached to the aluminum frame with rivets. Presenting a plastic plate for concrete formwork that combines strength and light weight that can be used 30 to 40 times for a concrete formwork that can only be used 15 times.

However, in the end, the registered design is only a plastic plate instead of a veneer plywood in the conventional Euroform, and this plastic plate is an injection product with grid-type reinforcement on the non-molded surface, so it is not suitable for mass productivity, and durability and price competitiveness are weak. It is a product that is not currently distributed in the market.

There is also Patent Publication No. 10-2011-0040319 (published on April 20, 2011) [Synthetic resin formwork panel for concrete slab],

The above-mentioned published patent has excellent mechanical properties, is recyclable, has a large number of exclusive uses compared to plywood, can secure excellent exterior quality of concrete slabs, and presents a technology related to a synthetic resin formwork panel for concrete slabs with excellent lighting and workability are doing

However, the above-mentioned published patent is not used for the overall formwork, but is used only for slabs, and it is a technology that does not present a connection structure between a foam panel and a foam panel like the existing Euroform.

Furthermore, there is Patent Registration No. 10-1123941 (Registration Date February 28, 2012) [Plastic Formwork],

The above-mentioned registered patent proposes a plastic formwork in which a reinforcing frame that is injection-molded into the inside of the outer body cut to a certain length by extruding in the shape of a rectangular tubular cross-section is accommodated, and a local reinforcing structure is not employed to reduce the weakness of the corner. It has a main purpose to provide a plastic formwork with a configuration that fundamentally solves the problem without

However, since the reinforcing frame is manufactured by the injection method, there is a limitation in productivity, and since the incision groove for inserting the fastening pin must be processed after extrusion of the single-sided rectangular tube body, this also becomes a factor of lowering the productivity,

Since the space of the incision groove for inserting the fastening pin is narrow, the on-site workability is poor. If the incision groove is enlarged, there is no choice but to cause a problem in durability. This is an unrealistic technology in many ways because it is a product that has a high risk of durability problems such as bursting between the interconnected formwork and formwork panel. .

In addition, there is a patent registration No. 10-1163135 (registration date June 29, 2012) [a formwork for pouring concrete including an inner formwork partially made of transparent plastic material],

The registered patent relates to a formwork for concrete pouring in which at least a part of the formwork installed inside the building is formed of a transparent plastic material, which is also only at the level of replacing the wooden panel of the existing Euroform with a synthetic resin panel. This is not to suggest a technology that can replace Euroform.

Accordingly, the present invention replaces the existing formwork such as Euroform, which is composed of laminated wood panels such as veneer plywood and a metal frame, is lightweight and can be recycled and reused semi-permanently without generating waste. In particular, the main part is processed by the extrusion method It aims to provide a foam panel assembly for synthetic resin formwork that can secure mass productivity as much as possible and secure both technological superiority, which is the core task of a new product, and price competitiveness with existing products.

~1~, ~2~, etc. described in the present specification will be referred to only to distinguish that they are different components, and are not limited to the order of manufacture, and their names in the detailed description and claims of the invention are may not match.

When specifying an approximate direction reference that is not strict for convenience in describing the foam panel assembly (A) for synthetic resin formwork according to the present invention with reference to FIGS. 2 to 5,

In the state as shown, it is divided into top and bottom, left and right, front and rear (the front is also called a non-concrete contact surface or non-formed surface or inner surface, and the rear surface is also called a concrete contact surface or formed surface or outer surface), and detailed description of the invention related to other drawings Unless otherwise stated in the description and claims, directions are specified and described according to this standard.

First, the foam panel assembly (A) for synthetic resin formwork according to the present invention shown in Figs. 2 [C] and Fig. 3 is largely composed of a connection panel 10, a forming panel 20, and a reinforcing means.

The synthetic resin material connection panel 10 provided on the left and right sides of the molding panel 20 each has a connection pin insertion hole 13 (see FIG. 4 ), and both side panels 11 for connecting the foam panel and the foam panel. include

The forming panel 20 is also made of synthetic resin and provides a forming surface in contact with the concrete.

When the molded panel and the connecting panel are integrally molded, they are molded by extrusion or injection.

The groove 15 for accommodating the connecting pin insertion hole 13 during extrusion molding and the gap maintaining bar (not shown) for maintaining the gap with the foam panel connector located on the opposite side, such as when pouring the wall, is post-processed after extrusion. It is preferably molded by work.

The reinforcing means provided on the non-concrete contact surface of the connection panel 10 may be a first reinforcing member 32 (see FIG. 2 [A]) arranged inside the side panels 11 to support the side panels. .

The first reinforcing member 32 of FIGS. 2 [C] and [A] is composed of an outer shell 32A and a core material 32B, specifically, a shell composed of a square extruded pipe having rounded corners in cross section, and this pipe shell It is composed of a wood core material cut and inserted to fit, and can be fixed by driving general nails or screws through the side panel 11 from the outside and driving it into the wood core material 32B.

Also, in the field, instead of the first reinforcing member 32, it is possible to cut and utilize a piece of wood that can be easily obtained at a construction site.

Unlike FIG. 2, the first reinforcing member M32 of FIG. 3 is a synthetic resin injection product, and a first contact portion A32 in contact with the inner surface of the side panel 11, respectively, and a second contact portion in contact with the inner surface of the molding panel 20 ( B32), and a body m32 to which the first and second contact portions are coupled.

In addition, having a cutout a32 formed extending from the first contact portion A32 to one side of the body m32, use a screw (or a rivet may be used) to penetrate from the outside of the side panel 11 and fasten the first contact portion A32 If there is a mold error, the first reinforcing member and the foam panel do not fit snugly, or in the case of recycling the used foam panel (A) at the site. Since the height of the first contact portion A32 is reduced when the cutout portion a32 is narrowed, it is possible to prevent a situation in which the first contact portion of the first reinforcing member protrudes from the side panel 11 .

In addition, the cutout (a32) also serves as a weight loss function, and reinforcement meat is provided around the cutout (especially on the body (m32) side) to prevent weakening of strength due to the cutout. This reinforcing method is also introduced into the reinforcing rib (b32) formed on the upper surface of the body (m32).

Conventional Euroform, which has a size of 300 to 1,000 mm in width, usually penetrates through the edges even if the wooden plywood forming the pouring surface is coated. I have to do

If the width is made smaller, the length between the two ends is that much narrower, and the degree of damage caused by concrete penetration is more severe, and the number of times of use is shorter by that much.

It is the foam panel assembly (A) of FIG. 3 that can solve this problem, and even in the case of a molded panel of about 60 to 200 mm (especially around 150 mm), since it is a synthetic resin material, there is no problem of damage due to concrete penetration, a product suitable for a niche market becomes this

It is preferable that the first reinforcing members 32 and M32 of FIGS. 2 and 3 have a size, structure, and coupling position that do not cover the connection pin insertion hole 13 or interfere with the connection pin insertion operation.

On the other hand, in the modified example of the foam panel assembly (A) for synthetic resin formwork shown in the exploded perspective view of FIG. (A) is differentiated from what constitutes it.

Divide the width of the molded panel 20, such as 100, 150, 300, 600 mm, which is often used by extrusion or injection, in a situation where a width of about 100 to 1,000 mm is required depending on the field situation (formation of foam panel) Various molded panel divided body (d20) width can be selected from 1 to 99% of the width of the panel 20) to become a form panel powder (Ad)

It is possible to cope with various molded panel width demands in a way that two form panel powders are assembled without the need for a mold for form panels of all specifications, so productivity, inventory management convenience, and The effect of improving unit price competitiveness can be obtained.

For reference, in this specification and claims, 'foam panel assembly' associated with reference sign 'A' is used interchangeably with 'foam panel' when referring to, except for reinforcing means.

The coupling means of the two form panel powders (Ad) each having the side panels (d11) constituting one connection panel (10) may be implemented by the first reinforcing means.

In addition, in the contact surface of the molded panel divided body (d20) in contact with each other in the combined foam panel powder (Ad), for example, a dove-tail-shaped male and female coupling part used when combining wood such as furniture can be introduced, and other The ease of bonding can be improved by introducing a 'C'-shaped groove and protrusion or a '┗┓'-shaped stepped structure that interlocks with each other.

Furthermore, in order to improve the bonding force at the contact surface of the molded panel divided body (d20) of each foam panel powder (Ad), on the non-concrete non-contact surface of the molded panel divided body (d20), a rear-projecting connection protrusion (21a), and the side surface from this connection projection Introduced the fastening protrusion powder (d21) composed of the protruding locking protrusion (21b),

When the two form panel powder (Ad) are combined, the fastening protrusion powder (d21) is combined to form the fastening protrusion (21),

A fastening body is introduced as a coupling means, and the fastening body preferably has a fastening groove corresponding to the shape of the fastening protrusion.

In particular, the fastening body is configured such that the first reinforcing means 32 also functions, so that the first reinforcing means 32 and the divided body d20 are combined to form a non-concrete contact surface (ie, rear) of the formed panel 20 . A fastening groove (32a) having a locking portion (32b) corresponding to the locking projection (21b) of the connecting projection (21a) of the forming panel divided body (d20) can be formed in a contact portion.

Next, the foam panel assembly (A) for synthetic resin formwork according to the present invention, shown in FIGS. 4 to 6, is a connecting panel for interconnection of both sides and upper and lower metal edges of the euroform of FIG. 1, that is, the form panel and the form panel. Let's look at a modified example having the same connection panel (10).

Left and right side panels 11A and 11a, respectively, can be seen in FIGS. 4 and 5, and a molded panel and an assembled type) (11B, can be seen in FIG. 6, and is integral with the molded panel) and an upper and lower panel (11P, of FIG. 5) As can be seen in the successive drawings of the top and front views in the block on the right, the left and right side panels or the molded panels, or both, are assembled)

As in the expression 'connection of form panel and form panel', for convenience, the term 'foam panel' is used for the configuration that is mutually fastened by the connecting pin (P), and the term 'form panel assembly' (A) related to the category Name and 'form panel' are used together.

It is preferable that the shape of the connection panel 10 is the same as or similar to that of Euroform in consideration of familiarity and convenience at the work site, and mixed use with the existing Euroform.

Therefore, the insertion hole 13 for the connecting pin (P) and the groove 15 for accommodating the gap maintaining bar (not shown) for maintaining the gap with the foam panel connector located on the opposite side, such as when pouring the wall. It is formed on the side panel and the upper and lower panels.

' 등의 형상을 갖는데, 필요에 따라 '

' 형상의 연결핀이 사용되도록 삽입공의 형상은 원형으로 변형될 수도 있다.The illustrated connection pin (P) is usually referred to as a 'wedge pin' and is '

It has a shape such as ', and if necessary, '

The shape of the insertion hole may be transformed into a circular shape so that a '-shaped connecting pin is used.

Unlike the foam panel assembly (Ac) such as a member for forming an outer corner shown in FIG. 7 , the conventional Euroform type foam panel assembly (A) shown in FIGS. 4 to 6 is a plate-shaped molded panel 20A, FIG. 4 And it can be confirmed in FIG. 5, and is assembled with the side panel) (20B, can be confirmed in FIG. 6 and is integral with the panel). In the conventional Euroform, laminated wood panels such as veneer plywood were used for this molded panel.

However, in the foam panel assembly (A) for synthetic resin formwork according to the present invention, the molded panel is extruded independently or together with the side panel to secure productivity, thereby securing both technical superiority, which is the core task of the product, and price competitiveness with existing products. making it do

4 to 5 are respectively a perspective view in [A] and a plan view in [B],

In the form panel assembly (A) having the assembled side panel 11A and the molded panel 20A of FIG. 4, the side panel is in contact with the side surface of the molded panel and a part of the non-formed surface (or the non-concrete non-contact surface) of the side panel C1 ) and the non-formed surface contact portion C2, and the side panel 11A and the formed panel 20A can be firmly coupled and fixed from the rear surface of the non-formed surface contact portion C2 side by using a fastening means such as a bolt. .

' 형상을 갖고, 측면패널의 좌우 절곡부의 외측에 성형패널의 후면이 접촉하며, 역시 측면패널의 좌우 절곡부측 배면에서 볼트 등의 체결수단을 이용하여 측면패널(11a)과 성형패널(20A)을 확고하게 결합·고정할 수 있다.In addition, in the form panel assembly (A) having the assembled side panel (11a) and the molded panel (20A) of FIG. 5, the side panel has an outline shape of an approximate cross section.

' shape, the rear surface of the molded panel is in contact with the outside of the left and right bent parts of the side panel, and the side panel 11a and the molded panel 20A are connected using fastening means such as bolts on the rear surface of the left and right bent parts of the side panel. It can be firmly combined and fixed.

It is preferable that the assembled side panel and the molded panel of FIGS. 4 and 5 are each manufactured by extrusion molding.

In contrast, in the form panel assembly (A) having the integral side panel 11B and the molded panel 20B of FIG. 6, the side panel and the molded panel are integrally extrusion-molded.

On the other hand, the outer corner member for forming an outer corner such as a corner portion of a wall is substantially

(The direction specification related to the description in FIG. 7 is divided into top and bottom, left and right, front and back in the state as shown based on the right front perspective view of FIG. , the rear surface is also referred to as the concrete contact surface or the forming surface or the outer surface))

The rear edge where the two side panels 11a meet finely meets the concrete molding surface (refer to the use state plan view of FIG. 7 [B]).

The foam panel assembly (Ac) for forming the in-corner is also molded through extrusion.

Further, in FIGS. 4 to 7 , the side panel and the upper and lower panels of the connection panel undergo an insertion hole 13 for the connection pin P after extrusion molding and a recess 15 forming process for accommodating the gap maintaining bar. For the formation of balls and grooves, it is desirable to improve productivity by putting a panel cut to a standard length unit using a special custom equipment into a mold and processing it at once using tools such as drilling, grinding, and punching. When post-processing a functional part in a direction crossing the extrusion direction, the foam panel assembly according to the present invention does not have an internal space, so there is no problem of damage to components due to processing pressure, which is also a factor that can contribute to improvement of processability and productivity.

Next, the foam panel assembly (A) for the synthetic resin formwork instead of the existing Euroform shown in FIGS. 4 to 6 is to assemble the upper and lower panels 11P in addition to the side panels or the molded panels, or both.

The upper and lower panels 11P may have, for example, the shape shown in the left block of FIG. 5 . As shown in the upper plan view and the lower front view in the block, the upper and lower panels 11P have a fastening plate 11p and are fixed by a bolt or the like in a state in which the fastening plate is brought into contact with the inside of the side panel, and additionally formed A fixing plate in contact with the non-formed surface of the panel may be further formed to enable bolting to the molded panel.

The material of the upper and lower panels 11P may be a synthetic resin product that is post-processed after extrusion molding, and a groove for accommodating a connecting pin insertion hole and a gap maintaining bar, or injection-molded at a time, or a metal upper and lower panel such as a conventional Euroform.

In addition, a fastening member such as a fastening plate for fastening with a side panel or a molded panel, or both, may be manufactured integrally with the upper and lower panel body or assembled post-mortem, and the material may be metal or synthetic resin.

Next, the reinforcing means 30 is provided on the non-concrete contact surface of the connection panel 10 to strengthen the side panels, upper and lower panels, or molded panels, or to strengthen the bonding state between each panel.

The 'type second reinforcing member (31B) is formed with a plurality of thinning holes (31h) for weight reduction,

A soft pin insertion hole and a fixing bolt insertion hole are formed in the side panel contact portion.

In contrast, the second reinforcing member 31C having a straight cross-section shown in FIG. 5 prevents damage to the side panel due to the connecting pin head when the form panel and the form panel are connected by the fastening of the connecting pin P, and the form By strengthening the connection between the panels, it is possible to prevent the concrete from leaking or even bursting due to the gap between the foam panels being widened during the concrete pouring process, vibration compaction process, and curing process.

The function of the second reinforcing member 31C of FIG. 5 is basically a function of the second reinforcing members 31A and 31C of FIGS. 4 and 5 as well.

The second reinforcing members 31A, 31C, and 31B of FIGS. 4 to 6 may be deformed as needed to the main body (both side panels and the forming panel) of any form panel assembly of FIGS. 1 to 6 .

Next, the first reinforcing member 33 of the reinforcing means 30 serves to connect and strengthen the side panel and the side panel and can be seen in FIGS. 4 and 7 , and although the size and shape are partly different, they perform the same function. .

That is, the first reinforcing member 33 is a first having a fitting hole 33a corresponding to the connecting pin P insertion hole 13 formed in the connecting panel 10, in particular, the side panels 11A and 11b, respectively. and second binding portions 33A and 33B, and a connecting portion 33C connecting the two binding portions.

In addition, the fitting holes 33a of the first and second binding portions 33A and 33B are formed at mutually shifted positions,
