Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a formwork panel for concrete pouring of a reinforced concrete structure, without dismantling and removing the inner formwork panel after pouring the concrete, The present invention relates to a drive-in type formwork panel used as an interior base for a ceiling base.

[0002]

2. Description of the Related Art Conventionally, as a formwork used for concrete driving in the construction of a reinforced concrete building, a formwork in which a cedar plate having a thickness of 9 to 15 mm is reinforced with a square bar of 45 to 60 mm has been mainly used. After that, veneer plywood, steel plates, composite plastic plates, etc. came to be used due to their economical efficiency and performance. However, these formwork must be dismantled and removed after placing concrete, so it is necessary to build them up on the assumption that they will be removed, and concrete formwork requires a high level of technology. It also requires a large number of man-hours to dismantle and remove.

From this fact, as a means of greatly saving labor and reducing man-hours, a drive-in type form panel has been developed which is used as a wall / ceiling base of a building without dismantling and removing the form side panel on the indoor side. Japanese Patent Laid-Open No. 62-5443, Japanese Patent Laid-Open No. 5-
No. 171723, JP-A No. 11-44026,
There are many proposals such as Japanese Utility Model Registration No. 3045801, which have become quite popular.

The hitherto typed formwork panel proposed heretofore has a great effect on the omission of the dismantling and removal of the formwork panel and the labor saving of the construction of the wall and ceiling foundations, and also the labor saving of some wiring work. There is something. However, the weir of the formwork panel for the interior base is 50mm from the pressure resistance when placing concrete.
It is a very thick waterproof insulation board, and it has a structure in which a splint made of special resin or parallel plywood is embedded and joined to it, and the spout only protrudes about 10 mm from the surface of the waterproof insulation board.
When the wall material is stretched directly on the pier, the depth of the space is about 10 mm.

Therefore, there is no problem with only the wiring, but since the depth is shallow, it is necessary to have a partial electric wire protection tube for preventing accidents when nailing a wall, installation of a buried type outlet or water supply.・ The depth of gas pipes in the wall is insufficient, and it is necessary to cut and remove the waterproof insulation at the time of construction.
There has been a demand for a formwork panel that allows easier piping.

Further, when it is used as a ceiling base, since the protruding portion of the pier is as short as 10 mm, it is difficult to construct a hanging tree or a hanging metal fitting, and it is difficult to form a hanging ceiling by passing a duct through the ceiling.

On the other hand, the wooden form panel using wood for the weir is not used as a driving form, but rather is required to be completely removed from the standpoint of termite control, and the wooden dam is made of styrofoam. The slab that has just been stretched does not need to be omitted because it requires work such as hitting a fixed anchor to the skeleton concrete wall later and striking the pier of the inner wall base material, which has no merit for the cost. It was

[0008]

[Problems to be Solved by the Invention] While taking advantage of the technology of using a formwork panel as an interior groundwork for a wall / ceiling, the work associated with wiring, piping, etc. is facilitated and labor is saved. It aims at facilitating and accurate building work.

It has been found that a space having a depth of 30 mm or more and a width of 50 mm or more is required between the weir board and the interior wall board for facilitating installation of wiring / buried type outlets, piping work, etc. and labor saving. Even in the work of fixing the hanging device for the hanging tree to the pier from the side with screw nails, if the protrusion of the pier is 30 mm or more, it is very easy.

When building a formwork panel, it is necessary that the formwork panel be a straight interior in order to be used as an interior substrate. If there is a warp or an unevenness, it will appear on the wall surface or ceiling as it is. In addition to facilitating positioning and facilitating fixing after positioning, it is necessary to improve the method of fixing to the concrete wall.

In order to provide a space of 30 mm or more in depth with a conventional waterproof and heat-insulated drive type mold panel, the total thickness of the form panel is required to be 80 mm or more. Then, the indoor area decreases. Since it is not preferable to greatly reduce the indoor area, the total thickness of the formwork panel is limited to 75 mm or less here, and it is made to be close to about 60 mm of the conventional implantable formwork panel. Within this 75mm range, in order to achieve a space / pier projection with a depth of 30mm or more, pay attention to the thickness of the conventional waterproof insulation plate of 50mm, while maintaining the pressure resistance when placing concrete. The means for making the distance 45 mm or less was examined.

[0012]

The present invention is made to solve the above problems, and its gist is as follows. 1. A wooden mold board (3) and a waterproof heat insulating board (4) are sequentially attached to a wooden frame (2) having a thickness of 30 mm or more in order to form a driven formwork panel (1) for an interior ground. ) With a total thickness of 75 mm or less, this formwork panel
A space having a depth of at least 30 mm is provided between the interior wall plate (5) attached to (1) and the wooden dam (3) of the formwork panel (1). 2. Cut a groove (2d) for a knuckle on each side of the frame (2) of the formwork panel (1) facing each other, and fit a knuckle (6) on only one groove. Join formwork panels together. 3. The wooden dam (3) is composed of a plurality of wooden veneers (3a) having a thickness of 9 to 15 mm, and the waterproof heat insulating plate (4) has a thickness of 1
A styrene foam plate of 0 to 30 mm is used. 4. The side of the formwork panel that contacts the concrete of the waterproof heat insulating plate (4) is made slightly wider in both length and width than the wooden panel. 5. Waterproofing treatment is carried out by spraying or impregnating a waterproof paint on a wooden panel consisting of a frame (2) and a wooden dam (3).

The construction method using the formwork panel of the present invention is as follows. 1. Joiner (1 for heat insulation board when placing wall concrete
Without removing a part of the extension screw (15) of 4), the nut with washer (22) is screwed into and fixed to the remaining extension screw. 2. After building the formwork panel for the ceiling and arranging the reinforcing bars,
Install using at least six or more depth limiting screw screws (20) throughout the formwork panel.

By using the formwork panel of the present invention as described above, the work of assembling the formwork panel can be performed easily and accurately, and the auxiliary work such as wiring and piping work can be facilitated to save the labor.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below based on the embodiments shown in the drawings. FIG. 1 shows a partial cross-sectional perspective view of the formwork panel of the present invention. The formwork panel 1 is formed by attaching a weir board 3 and a waterproof heat insulating board 4 to a stile frame 2.

In the frame 2 shown in FIG. 2, a long frame frame 2a having a length of 3000 mm and a short frame beam 2b having a length of 520 mm form a rectangular frame of 3000 mm × 600 mm, and the rectangular frame has an equal interval. Distributing two middle piers 2c of 2920mm in length,
A vinyl acetate-based woodworking adhesive was applied to the contact points of each pier and fixed with nails to form a pier frame 2 of a wall form panel. Then, a width 10 is formed at the center of the outer peripheral surface of the frame piers 2a and 2b forming the outer periphery.
A groove 2d having a depth of 6 mm and a depth of 6 mm is engraved over the entire circumference. As timber wood, a large number of thin 5 mm cedar boards were pasted together, parallel plywood with little bending warp was planer finished, and 40 mm x 40 mm square cross-section timber was cut out and used.

Then, at a position 1500 mm from the lower ends of the long frame pier 2a and the middle pier 2c of the pier frame, a diameter 10 mm and a depth 3
An anchor screw guide hole 2e having a diameter of 4 mm and a spot facing of 2 mm is drilled. Further, the frame of the formwork panel for the ceiling is the outer frame of the frame 2a.
1800mm, middle pier 2c 1720mm, short frame pier 2
b was 520 mm, the structure was the same as for walls, and only the size was shortened to 1800 x 600 mm.

The size of a general formwork panel is the width (short length).
It has a length of 600 mm and a length of 1800 mm, but for walls, the length is 2700 mm, 3000 mm, 330 depending on the height of the wall.
There are various sizes such as 0 mm. Furthermore, the wall height becomes higher,
When the gravity of concrete when placing concrete becomes high and reinforcement of pressure resistance is required, narrow the intervals between the long piers and set the number of middle piers 2c so as to support the dam at many points. It is most effective to increase.

The stile frame 2 is used to reinforce the weir plate when pouring concrete and to form a space for wiring and piping in the wall between the weir plate and the inner wall plate after concrete solidification by utilizing the thickness of the pier and the weir plate. The space for wiring in the ceiling is formed between the ceiling plates, and the hanging tree is fixed in the case of a suspended ceiling. And, the weir board 3 withstands the pressure at the time of pouring concrete, maintains the shape of the formwork, and after the solidification of concrete, wiring and
It serves as a stapler for pipe supporters and a receiving plate for screws. Further, the waterproof heat insulating plate 4 prevents leakage of concrete during pouring of concrete and water wetting of the wooden dam and the wooden frame, and prevents dew condensation by infiltration of moisture and heat retention after solidification of concrete.

The wood frame 2 is made of a cedar board, which is generally unsuitable as an exterior material and is a first-class material of thinned wood with many knots, which is processed into a thickness of 10 mm and a width of 100 mm, and a length of 6 mm.
Cut to 00 mm to create veneer 3a, and then cut veneer 3a into 3
Using 0 sheets, apply adhesive to the entire back surface of the frame 2,
It was struck with nails to form a cough board 3. The weir board 3 may be a plywood control panel as long as it satisfies the pressure strength at the time of pouring concrete, but there is also a formalin problem in a concrete structure with a high degree of tightness, and it is inexpensive such as Sugimatsu Takashi which does not contain formalin. A first-class veneer is preferred. Further, the width of the plate does not need to be constant as 100 mm as described above, and even if plates of various widths are mixed, the total width is 3000 mm or 180 mm.
The specified size should be 0 mm.

It is more preferable to waterproof the wooden panel manufactured as described above by spraying or impregnating the waterproof paint with spray paint so that the jetty 2 and the dam 3 will not be deformed by rainwater during construction work. Further, waterproof processing may be applied to the cut out timber or veneer.

Even in a commonly used removable formwork panel, a wooden dam is often used in a thickness of 9 mm to 15 mm. If the thickness is less than 9 mm, the pressure resistance at the time of pouring concrete is insufficient, so it is not generally used. If it is too thick, the formwork panel becomes heavy, which is not preferable.

Since the wooden dam 3 passes through the electric wires and pipes in the wiring and piping work after the concrete is poured, a part of the pier may be cut or punched, so that the strength decrease at that time is complemented by the dam. The veneer 3a and the sprues 2a, 2b, 2c need to be firmly bonded with nails, screws, or an adhesive.

The waterproof heat insulating plate 4 is a styrofoam plate having a thickness of 15 mm. This 15 mm-thick waterproof heat insulating plate 4 is 600 × 3000 mm on the weir board 3 side and 602 × 3002 mm on the concrete side, and is cut with a taper of 1/15 at the end to make a 600 × 3000 mm wooden panel. An adhesive agent was applied to the wooden dam 3 of Fig. 1 and laminated and pressed to form a formwork panel 1 as shown in Fig. 1 for a wall.
If the thickness of the waterproof heat insulating plate 4 is 15 mm, if it is 10 mm or less, there is a problem in heat insulation and it is fragile and poor in handleability, and if it is 30 mm or more, the total thickness of the form panel becomes 75 mm or more. Because it cannot reach.

The waterproof heat insulating plate 4 is made wider than the wooden weir plate 3 by pulling the formwork panels together with a shrimp vise / screw screw at the time of building and pressing and compressing the watertight heat insulating plates against each other to bring them into close contact with each other. This is because The degree of widening should be very small, and it is sufficient if there is no gap between the waterproof and heat insulating plates when the form panels are brought into close contact with each other. If the degree of widening is large, a great deal of force is required to press and compress. Also, when compressing the entire contact surfaces of the waterproof heat insulating plates, a very large force is required. Therefore, it is preferable to cut out all or part of the taper to reduce the contact area.

Applying an adhesive agent to the entire surface of the wooden panel to attach the waterproof insulating plate 4 to the wooden panel and bonding them together is one of the measures for preventing the concrete and the form panel from peeling off. The peel strength between the concrete and the waterproof heat insulating plate after the concrete is hardened is so strong that it cannot be separated unless the waterproof heat insulating plate is broken.
However, when the waterproof heat insulating plate 4 and the wooden dam plate 3 are joined with a nail or the like, the peeling strength becomes very weak, and the peeling occurs between the waterproof heat insulating plate and the wooden dam plate, so apply or spread the adhesive on the entire surface, It is necessary to bond the entire surface.

The ceiling wooden panel 1 was also adhered to the entire surface with a 15 mm-thick styrofoam waterproof insulation plate 4 cut with a 1/15 taper to form a ceiling for a formwork panel.

The procedure for manufacturing the formwork panel 1 is as follows:
The order of the wooden clapboard-> waterproof heat insulating board is good, and the couchboard 3
It is not suitable to attach the waterproof heat insulating plate 4 and the water heat insulating plate 4 to the peg frame first, because the waterproof heat insulating plate will be scratched with nails or screws.

FIG. 3 is a sectional view of the formwork panel 1. In this embodiment, the pier 2 has a thickness of 40 mm, the dam 3 has a thickness of 10 mm, and the waterproof heat insulating plate 4 has a thickness of 15 mm, and the total thickness is 65 mm. Therefore, the protrusion amount (V) of the pier 2 from the weir plate 3 is 40 mm, and the space between the weir plate 3 and the inner wall plate 5 when the inner wall plate 5 is stretched on the indoor side of the pier frame is deep. (v) is 40 mm, width
(w) is 146 mm, which is enough space for wiring and piping work. Since this is about 10 mm in the conventional method of embedding a splint in a thick waterproof insulation board, it is possible to obtain a depth of space that cannot be obtained by the conventional method.
Since the space required for the work should be at least 30 mm or more, the thickness of the pier may be 30 mm.
Has a thickness of 9 to 15 mm, and the thickness of the waterproof insulation board 4 is 10 to 30 mm.
If

FIG. 4 shows a method of adjoining the formwork panels 1 laterally adjacent to each other. According to the Yatoinane method of the present invention,
After the frame panels have been manufactured at the factory, the frame panels of the adjacent frame panels are fitted in the groove lines 2d of the recessed strips later, which are matched with the length of the rectangular groove. A ridge can be formed by fitting the tongue 6 on either the left or right of the formwork panel according to the workability at the construction site.

There is a proposal for a book strip in Japanese Utility Model Laid-Open No. 62-5443, but in this booklet, a groove and a ridge are directly processed on the frame pier, so when the weir board is stretched, either the groove or the groove is formed. It must be decided to make the opposite side a convex line, and there is no degree of freedom to change the concave and convex after the weir is stretched due to the work convenience.

FIG. 5 shows a cross-sectional view when the formwork panels are joined at a right angle. At the corners and the joints between the walls and the ceiling, the formwork panels are joined at right angles as shown in FIG. In this case, the groove 2d of the form panel connected at right angles
Needs to be changed from the lateral side position (2d) shown by the dotted line to the position 2d in the thickness direction shown by the solid line. In addition, a width of 65 mm and a thickness of 25 mm in the joint space at the wall-side end of the ceiling formwork panel.
A waterproof insulating plate 7 made of styrofoam of mm is retrofitted. Then, the crosspieces of the ceiling formwork panel and the wall formwork panel are tightened with screw screws 20.

In the agitation system of the present invention, since the outer frame stiles 2a and 2b have a square cross section and the concave groove is located at the center of one side surface, the frame frame panel for the ceiling and the wall for the wall are particularly suitable. When the formwork panels are joined, it can be changed by assembling by turning 90 degrees so that the groove portions 2d of the crosspieces 2a on both sides of the formwork panel at the corners for the ceiling come from the side surface to the inner wall side. Therefore, only one type of frame pier can be processed. Further, when the cross section is rectangular, two types of frame piers having concave grooves on the side surface of the formwork panel and frame piers having concave grooves on the inner wall side are required.

When assembling the formwork panel, if the wooden panel is not waterproofed, the floor side end of the wall formwork panel where the wood mouth is exposed is waterproofed and built on the formwork panel. Number in the order of inclusion. And after the reinforcement of the wall reinforcement,
Build the formwork panels in numerical order. For building, the level of the first formwork panel should be adjusted exactly and fixed to the floor in line with the black line. Then insert the mold panel 6 in sequence, align the top level exactly as in the conventional work method, pinch the frame piers with a shrimp vise, tighten them tightly and temporarily fix them, Screw the frame piers together with a screwdriver with a diameter of 4 mm and a length of 75 mm with a screwdriver to sew the mold frames together and then fix them to the floor.

The building of the form panel on the inner wall side is completed,
In a conventional manner, a separator hole is penetrated through the wooden dam 3 and the waterproof heat insulating plate 4 of the formwork panel to form a 9 mm hole, and the outer removable formwork panel is also provided with a corresponding hole. FIG. 6 shows a cross-sectional view when the separator is attached. A separator 9 for concrete wall thickness of 180 mm is placed between the outer wall panel 8 and the inner wall form panel 1, the outer wall side on the upper side of the drawing is fastened with the home tie 10, and the vertical butter pipes 11 arranged at 200 mm intervals and 600 mm intervals. Then, the 6-level horizontal flap square pipe 12 is driven into the elongated hole of the home tie 10 and the wedge 13 is tightened. 2 on the inner wall side to the heat retaining plate joiner 14
Screw the extension screw 15 for 5mm to the home tie for inner wall 1
Tighten with 6 and drive the horizontal flap square pipe 17 into the long hole of the home tie with a wedge 18 to tighten it.

As shown in FIG. 7, on the formwork panel to which the home tie 16 has been fixed, a stainless steel screw for anchor having a diameter of 5 mm and a length of 105 mm is sequentially inserted from the inside of the anchor screw guide hole 2e formed in the pier. Insert the screw 19,
Screw the head so that it is completely buried in the sculpture. About 45 mm of the tip of the screw screw 19 also serving as an anchor penetrates the styrene foam waterproof heat insulating plate 4 and projects to the concrete wall wall concrete placing portion, but the screw remains stuck to the waterproof heat insulating plate. There is no gap between the screw and the screw. The number of anchor screws 19 for walls may be about four per one form panel.

After all the wall form panels have been fixed, the slab form holding work is performed with the support and the frame.
Supports the square pipe of ceiling flap.

Then, as shown in FIG. 5, the upper end of the wall form panel is aligned with the stile of the ceiling form panel, and after confirming the position, the ceiling form panel and the wall form panel are fixed with a screw screw 20 of 105 mm. To fix. The screw 20 is screwed in until the head contacts the waterproof insulation. This slab part is laid in front of the reinforcing bars, since it is easy to work from above, so lay a formwork panel and press it from above to check if it floats from the inside of the room. Fix the frame piers of the frame panel with 75 mm screw screws (not shown).

After that, as in the conventional case, a vinyl adhesive tape is put on the waterproof and heat insulating joint portion to make a leak-proof seal.
At the joint between the wall and the ceiling, the joint at the end of the waterproof waterproof insulation board at the end is also marked, and the entire inner wall / ceiling form near the ceiling is waterproofed.

A slab rebar is laid on the ceiling formwork panel, and a scaffolding board is passed over the rebar. From above the scaffolding board to the frame of the formwork panel below the reinforcing bar, as shown in FIG. The depth limiting screw 20 shown was screwed in. The depth limiting screw 20 is made by screwing a stainless steel washer 21 having an outer diameter of 22φ, an inner diameter of 4φ, and a thickness of 0.3 mm into a half-screw type stainless screw screw having a diameter of 5 mm, a length of 90 mm and a length of a screw portion of 60 mm. .

Each of the depth limiting screw screws 20 is attached to each of the short piers 2b of the ceiling formwork panel and the long piers 2 respectively.
14 pieces per 3 form frame panels are screwed into a and 2c from above the waterproof heat insulating plate 4. Thus washer 21
The part exposed to the upper side serves as an anchor for concrete placement. The anchor of the screw screw 20 is less likely to come off than a general nail anchor, and workability is improved in the method of screwing with a screwdriver rather than hammering the nail between the reinforced reinforcing bars with a hammer. The 14 anchors here take into consideration the load on the ceiling, and 6 anchors are sufficient to prevent the falling and peeling of only the ceiling formwork and ceiling material.

According to this method, an opening, a hole for wiring and piping, piping for a buried wiring pipe, etc. are formed, and after all pre-preparation is completed,
The thickness of the slab is 220 mm and concrete is poured. When pouring fresh concrete, the formwork panel on the inner wall side was not deformed, there was no spillage or water bleeding, and there was no particular problem.

After curing and curing, the support work, the flap material 11, 12,
The home tie 10 and the like are removed, the outer wall control panel 8 is removed, and the screw portion of the separator 9 exposed outside is broken off. The inner wall side also has supporters, flaps 17, home ties 16, etc. removed, and the joiner's extension screw 15 also has 3 screws on the center of each wall and on both sides.
Remove only the formwork panels. As shown in FIG. 9, attach the washer nut 22 to the remaining extension screw 15 of the joiner.
Insert it and tighten it firmly to make a wall anchor.

The wiring work is carried out by pulling the electric wire into the wall through a wiring pipe of a concrete wall from the outside to an embedded type outlet fixed to the pier with wood screws at a predetermined position.

The staple for fixing the wiring is driven into the wood weirboard at the back of the wall. The wiring is about 40 mm deep from the surface of the inner wall, so if the resident accidentally nails the wall,
If it is 8 mm or less, the wiring is not damaged and the need for a wire protection iron pipe is eliminated.

Supporters for water and gas pipes are also fixed to the wooden dam behind the wall with 20 mm wood screws. When extending horizontally with some wiring / piping, cut each splint into two pieces with a circular saw to the required width and pull out the inside to make wiring / piping grooves.

The construction of the suspended ceiling is carried out in the usual manner by fixing a 40 × 30 square hanging tree to the crosspiece of the ceiling formwork panel with a 75 mm screw screw.

The wall is made of gypsum board with a thickness of 12.5 mm, and a wall cloth is stretched on the gypsum board for finishing. When putting a gypsum board,
There were no particular distortions or irregularities. A glass wool mat with a thickness of 40 mm is installed on the partition wall for sound insulation.
Cut it to a width of 6 mm, embed it in the space with the wall, stretch the plasterboard on the inner wall, and stretch the wall cloth.

[0049]

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, the wiring / buried type outlet can be attached, and the piping work can be facilitated and labor-saving. It is also possible to fix the hanging fishing tackle on the ceiling to the pier with a screw or nail from the side. After curing the concrete, the cutouts and reinforcement of the pier can be done with a circular saw and an electric screwdriver, just like in a wooden construction, and there is a great degree of freedom and work is easy.

After the construction of the inner wall, it is possible to use a first grade material such as cedar, which has many knots and is not suitable as a surface covering material, for the weirboard which is not visible to the inner wall of the wall. This method can be applied to veneer plywood, but veneer plywood has a formalin problem, and veneer plywood is preferable from the viewpoint of health. In particular, the use of domestically produced thinned timber, which has a limited use, can contribute to national land conservation by utilizing domestic forest resources and forest maintenance such as thinning.

Installation of a groove on the frame pier of the form panel, installation of a groove, punching of a guide hole for an anchor,
Due to the use of depth limiting screws and the use of separator extension screws as anchors, the work of building the formwork can be done almost exclusively with an electric screwdriver, making it extremely easy and accurate. In addition, the location where the concrete is embedded is only the indoor inlet of the wiring and piping, positioning is easy, and it is no longer necessary for the electrician / plumber to attend and instruct the formwork assembly.
