Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a modular coordination for efficiently and economically forming a formwork of a frame, particularly in a building constructed by a column / beam rigid-frame reinforced concrete structure.

[0002]

2. Description of the Related Art Conventionally, when forming a formwork of a concrete building, a plywood formwork panel has been widely used. This type of formwork panel consists of a formwork plywood with a thickness of about 12 mm as a weir plate, and nails reinforcing girders at the peripheral edge and middle part of its back surface, which are connected vertically and horizontally. In doing so, the crosspieces at the peripheral edges of the adjacent formwork panels are nailed and joined together. This type of formwork panel is usually prepared in a certain size according to the standard dimensions of the formwork plywood, and the part that does not conform to the standard size is cut by the operator at the site as appropriate, and It is built with a pier.

[0003]

However, according to the above-mentioned conventional form panels, nailing between the crosspieces is indispensable for fixing the form panels adjacent to each other vertically and horizontally.
There has been a problem that the impact at the time of hitting the nail causes a slight shift in the erection position of the form panel, and it is difficult to correct the shift. In addition, it is extremely troublesome to cut off a part of the weir plate that does not conform to the standard dimensions of the plywood for formwork at the site, and to attach a pier to the back side, which takes time and work and reduces the construction accuracy. There was an inconvenience.

Further, when the mold is removed from the concrete after hardening, the form panel is dismantled while prying off the nails fixing the crosspieces with a bar or the like. At most, it was only a few times. Therefore, there is a problem that the amount of waste materials disposed on site increases, which leads to waste of wood resources.

Therefore, the present applicant can easily and accurately connect the form panels vertically and horizontally without nailing each other.
As a mold structure of a concrete building whose demolding is easy, a mold structure according to Japanese Patent Application No. 11-511183 has been invented and has been filed. This formwork structure prepares a flat formwork panel made of a plywood for a formwork having a sufficient thickness, and has a substantially U-shaped concave groove portion that can be fitted to an edge of the formwork panel. The form panel is installed while being temporarily fixed via a joiner.
This will improve the efficiency of the work of building and removing the formwork panels, minimize damage to the formwork panels, improve workability in formwork work, and increase the number of reuses of formwork panels. It intends to save timber resources.

Further, the present applicant has conventionally made an effort to reduce member costs and construction costs by modularizing the dimensions of building members constituting a building. Japanese Patent Application Laid-Open No. Hei 9-177336 discloses a residential building system in which the inner dimension (inter-interior dimension) of a wooden inner wall provided opposite to the inside of the frame is an integral multiple of a predetermined module. A system has been proposed, and according to this, it is possible to further promote the standardization and standardization of members constituting the inner wall.

The present invention has been made in connection with these inventions. In other words, the purpose is to build a skeleton with a reinforced concrete structure and provide an inner wall with a wood-based structure inside it so that the inner wall can be rationally and economically provided in accordance with a predetermined module. By providing modular coordination of formwork in which the layout of formwork panels is systematized in advance in relation to the dimensional relationship of the skeleton and inner wall, we aim to improve workability and reduce costs in framing work, The purpose is to promote effective use.

The present invention is particularly applied to a reinforced concrete building constructed by a column / beam rigid frame type structure.

The mold for forming the frame 1 is shown in FIG.
A plurality of formwork panels 3 as shown in FIG. The formwork panel 3 is a flat plate made of one formwork plywood, and has a thickness t so that sufficient strength and rigidity against concrete pressure can be exhibited without attaching a pier to the back surface. Is set to about 20 mm. Further, the width of the form panel 3 is cut in advance to several types of set dimensions described later, and further, a separator insertion hole 31 for inserting a separator for fastening the form and the like is provided at a predetermined position of each form panel 3. It is formed in advance in a plurality of rows and a plurality of stages.

The form panel 3 is held at the projecting and entering corners of the frame 1 via a form joiner 4 as shown in FIG. The mold joiner 4 is a member having a long and uniform cross-section made of resin or metal, and is a pair of concave grooves 4 having a substantially U-shaped cross section that can be fitted to the edge of the mold panel 3.
1 and these concave grooves 41 are integrally connected so that their opening surfaces are orthogonal to each other.

Then, as shown in FIG. 5, the respective edges of the form panel 3 adjacent to each other with the projecting corner and the entering corner of the frame 1 being inserted into these concave grooves 41 and screwed. Thereby, each form panel 3 is held at right angles to each other. At this time, in the protruding corner portion of the skeleton 1, the ridge corners of the skeleton 1 and the edges of the form panels 3 are aligned with each other. 3 is held at a position away from the corner of the frame 1 by the thickness t of the formwork panel 3.

In the form layout pattern shown in FIG. 2, the form panel 3 is a reference panel 3a having a width M.
And the wall end panel 3 whose width is [(1/2) M + Ft]
b, the column finding surface panel 3c having the width E, and the width (E
-Gt), which is composed of four types of prospective pillar panel 3d.

On both the inner and outer surfaces of the short-side wall portion 11, (p-1) reference panels 3a are continuously provided at an intermediate portion, and one wall end panel 3b is disposed at each end. Then, these are opposed inside and outside, so that the entire length S ₀₁
= PM + 2F-2t = L 01 -2t wall formwork is formed.

On the other hand, on both the inner and outer surfaces of the wall portion 11 on the long side,
The intermediate portion (q-1) piece of the reference panel 3a provided continuously, the wall end panels 3b of each respective one at both ends is arranged, by which they are out relative overall length S ₀₂ = qM
+ Wall formwork 2F-2t = L ₀₂ -2t is formed.

In the corners of the skeleton 1, prospective column panels 3 d, 3 d are respectively arranged to protrude outside a pair of walls 11, 11 orthogonal to each other with the corners interposed therebetween. A pair of pillar finding surface panels 3c, 3c are arranged opposite to the panels 3d, 3d, respectively, and they are continuously provided so as to be orthogonal to each other via the form joiner 4 outside the corner. Thus, the column formwork of the external corner post 10 having a square cross section is formed integrally with the wall formwork.

FIGS. 6 and 7 are explanatory diagrams showing the basic concept of modular coordination of the formwork when the building frame 1 of the building is composed of the internal corner pillars 12 and the wall portions 11.

The frame 1 has internal corner pillars 12 at four corners, and an inner wall 2 having a finish thickness F is provided inside thereof. Then, the length of the linear portion excluding the inner protruding portions formed at the four corners of the inner wall 2 is set to an integral multiple of the predetermined module M. Here, assuming that the length I ₀₁ = rM in the short side direction of the linear portion of the inner wall 2 and the length I ₀₂ = sM (r and s are integers) in the long side direction, the wall portion on the short side of the frame 1 11 length L ₀₁
= RM + 2F, length L ₀₂ of the long side wall 11 = sM + 2
It becomes F.

If the wall thickness of the wall 11 is uniformly G and the column width of the internal corner post 12 is E, the expected dimension D of the internal corner post 12 with respect to the wall 11 is D = GE−E. is there.

The frame 1 has a reference panel 3a having a width of M, a wall end panel 3b having a width of [(1/2) M + Ft], and a width of (EGt). Using the four types of form panels 3 of the column prospect surface panel 3d and the inner corner column outer surface panel 3e having a width of (E + t), a form layout pattern as shown in FIG. 7 is formed.

That is, on both the inner and outer surfaces of the short side wall portion 11, (r-1) reference panels 3a are continuously provided at an intermediate portion, and one wall end panel 3b is provided at each end portion. They are arranged so that they face inside and outside, so that the overall length S
_{01 = rM + 2F-2t =} L 01 -2t wall formwork is formed.

On the other hand, on both the inner and outer surfaces of the wall portion 11 on the long side,
(S-1) reference panels 3a are continuously provided at an intermediate portion, and one wall end panel 3b is disposed at each end thereof.
Since these are opposed inside and outside, the overall length S ₀₂ = s
Wall formwork _{M + 2F-2t = L 02} -2t is formed.

In the corners of the skeleton 1, prospective column panels 3 d, 3 d are respectively arranged to protrude inside a pair of walls 11, 11 orthogonal to each other with the corners interposed therebetween. At the inner side of the part, a pair of internal corner pillar outer panels 3e, 3e, are provided at right angles via a form joiner 4 so as to face the pillar prospective panels 3d, 3d, respectively.
3e are arranged at right angles to each other, and they are connected to each other via the form joiner 4 outside the corner. Each of the inner corner pillar outer panels 3e, 3e is connected to the outer side of the wall form of the wall portion 11, respectively. Thus, the column formwork of the internal corner post 12 having a square cross section is formed integrally with the wall formwork.

As described above, the reference panel 3a and the wall end panel 3b formed by associating the width dimension with the module M and the finish thickness F of the inner wall 2, and the width dimension by the wall thickness G and the column width E of the frame 1.
Several formwork panels 3 such as a pillar finding surface panel 3c, a pillar prospecting surface panel 3d, and an inner corner pillar outer surface panel 3e formed in association with are prepared in advance, and these are appropriately combined according to the shape of each part of the frame 1. By forming them continuously, it is possible to easily form the formwork of the frame 1 of the building in which the inner wall 2 is an integral multiple of the predetermined module M. For this reason, there is no need to cut the form panel 3 or attach a pier to the back surface at the site.

Then, a plurality of reference panels 3a are connected to the intermediate portion of the wall portion 11 so as to face each other inside and outside, and wall end panels 3b are connected to both ends thereof to form a wall form. Formwork panels 3 can be allocated in a well-balanced manner for the left and right. Therefore, the holding state of the wall form by the support work can be stabilized, and the finished appearance of the wall portion 11 can be improved.

The width of the reference panel 3a may be any size as long as a plurality of the reference panels 3a are connected in series and can be set to an integral multiple of the predetermined module M.
2) M may be set. Further, for example, two types of widths of (2/3) M and (1/3) M can be prepared and combined.

When the width of the form panel 3 is specifically set in accordance with the basic principle of modular coordination of the form of the present invention described above, the following is obtained.

For example, the module M of the inner wall 2 is 900 m
m, Finish thickness F of inner wall 2 = 50 mm, Wall thickness G of frame 1 = 15
0 mm, column width E = 450 mm, thickness t = 20 of formwork panel 3
mm, and the width of the reference panel 3a is 90 mm when the form panel 3 is cut from a 910 × 1820 mm plate (36 boards) which is a kind of standard size of plywood for general forms.
It is economical to make it 0 mm or 450 mm. In addition, the width of the wall end panel 3b is 480 mm, the width of the pillar finding surface panel 3c is 450 mm, the width of the prospective pillar panel 3d is 280 mm, and the width of the inner corner pillar outer panel 3e is 470 mm.

The form panel 3 is 1210 × 2420.
When cutting from a plywood for formwork of 48 mm (48 sheets), the width of the reference panel 3a is set to (2/3) M = 600 mm, and the width of (1 / 3) M
It is economical to use a form panel 3 of = 300 mm.

When the modular coordination of the formwork is actually applied to a building having various and complicated shapes, the formwork panel 3 having the five widths is required.
In addition, adjustment panels of other widths are required. They are used, for example, for special portions such as walls provided at positions deviated from the module reference line, around openings, and end portions of walls, and are prepared according to the shape of each of these portions. For example, as shown in FIG.
In the case where the wall-mounting column 13 having the column width E is provided in the middle portion of the wall-mounting column 13, a wall-mounting column wall panel 3f having a width of (E + 2t) is prepared, and is disposed on the wall side of the wall-mounting column 13. A pillar finding surface panel 3c is arranged on the finding surface side of the pillar 13, and a pillar finding surface panel 3d, 3d is arranged on the prospective surface side.
It can also be said. As described above, if the adjustment panels are prepared in accordance with the dimensions determined from the shapes of the module M of the inner wall 2 and the skeleton 1, the types and the number of the adjustment panels are the same as those of the reference panel 3a and the like. That is, the number is greatly reduced as compared with the number of sheets.

When a building of the same form is to be constructed on a site with different topographical and weather conditions, it is necessary to change the thickness of the heat insulating layer provided inside the outer wall, for example, depending on the specification of laws and regulations. However, even in such a case, the dimensions of the form panel 3 defined by the finish thickness F of the inner wall 2, that is, the wall end panel 3b having a width of [(1/2) M + Ft]. Is increased or decreased by the increase or decrease of the finish thickness F, and the frame 1 can be formed while keeping the dimensions of the other form panels 3 as they are.

As a result, the size variation of the entire configuration of the form panel 3 is limited, and it is possible to reduce material costs, facilitate material management, and improve construction efficiency.

Further, among the above-mentioned form panels 3, the reference panel 3a, the wall end panel 3b, etc., in which the same ones are arranged facing each other, are vertically and horizontally symmetrical with respect to their respective outer shapes. By forming the separator insertion holes 31 in advance, it becomes possible to build them up without distinction of upper, lower, left and right. The pillar finding surface panel 3c and the pillar prospect surface panel 3d or the pillar finding surface panel 3c and the inner corner pillar outer surface panel 3e which are arranged to face each other.
Among them, with respect to the pillar finding surface panel 3c having a small width, the separator insertion holes 31 can be formed at vertically symmetric and left / right symmetric positions, for example, as shown in FIG.

In addition, if a concrete release agent is applied to both the front and back surfaces of each form panel 3, it is not necessary to distinguish between the front and back surfaces. Thus, the work of setting the form panels 3 can be made more efficient, and the reuse of the form panels 3 is also promoted.

Finish thickness F of inner wall from skeleton surface, skeleton wall thickness G, column width E
In addition, the width dimension of the form panel is standardized in relation to the thickness t of the form panel, and the size variation of the form panel is limited, and the continuous pattern thereof is also standardized. The management cost can be reduced and the workability can be improved.

In addition, the standardization of the width dimension of the form panel further promotes the reuse of the form panel.
