The present invention relates to a form word for forming a column in a column-based building foundation suitable for construction of wood, such as a house.

The column-based building foundation replaces the traditional total aeration structure consisting of abandonment continually with the partition part between the outer circumference and the inner side, and has been recently proposed. As shown in Figs. 12 and 13, The underground road amount B is installed in a predetermined portion (the partition portion) of the outer base fabric A in an integrated state with the abandoned base A, and a columnar shape is formed on the upper surface of the base weight B. Or it is constructed by placing the pillar (C), which is a columnar concrete pillar at a predetermined interval.

(See Japanese Patent Laid-Open Nos. 57-133932 and 57-180734).

According to this column-based foundation structure, there are various advantages in terms of construction and cost as compared with the conventional whole abandoned grass structure.

(A) As the ventilation of the floor space is remarkably improved and the retention of moisture is eliminated, it becomes difficult to generate decayed bacteria such as mushrooms and molds, and the durability of the upper structure is improved.

(B) The floor space becomes wider, and it becomes advantageous for construction, maintenance such as the floor pipes.

(C) As the formwork is only the outer part, the construction efficiency is significantly improved.

(D) The amount of form, and the amount of concrete is at least low, so the cost is eaten cheaply.

In such a column-based foundation, the strut C can be formed in a columnar shape (or in a columnar shape) by placing a normal formwork on a weight-bearing upper surface and placing concrete on it.

As the form for forming the strut, various tubes such as plastic pipes, paper tubes, and hummers, such as vinyl chloride, can be used. However, the formwork due to such a tube becomes relatively large and large, and especially large quantities. It is disadvantageous in case of bulk transportation or storage.

Therefore, the present invention is to provide a form for forming pillars in column-based building foundation that can be divided into two divided states, which is advantageous for transportation or storage, and is easy to assemble when used, and can fully exhibit the formwork function.

The present invention is characterized in that the column-based building foundation is constructed by installing the ground weight integrally with the abandoned herb on the inner predetermined part of the outer abandoned apricot, and placing a strut at a predetermined interval on the upper surface of the center. As a formwork for forming a strut, a pair of formwork pieces formed by a half-split phase of a cylindrical body is provided with an engagement portion that can engage relative to each other in a vertical direction only in a cross-section facing each other so that two formwork pieces are formed. In the formwork for strut formation in the column-based building foundation which is comprised normally by connecting in the cross-sectional part which mutually opposes through the engaging part.

1 to 11 show an embodiment of the present invention.

In Fig. 10 and 11, (1) is the outer fabric base, 2 is the weight, (3) the columnar column is placed on the upper surface of the paper weight at a predetermined interval, (4) is the crosswood, and (5) is the foundation ( Iii).

The lumber 4 is attached by walking between the outer periphery base 1 and the support | pillar 3, and between adjacent support | pillars 3 and 3.

On the other hand, the foundation 5 is mounted on the upper surface of the outer fabric base 1 in a full length support state, and similarly to the crosswood 4, between the outer fabric base 1 and the strut 3 and neighboring struts 3. Also in (3), it mounts orthogonal to the horizontal bar 4.

In such a column-based construction foundation, the rowwood (4) is different from the crosswood mounted on the top surface of the abandonment in the conventional abandonment structure of the conventional abandonment, as described above. Since it is mounted in the two-point supporting state between the or between struts 3 and 3, there is a necessity to use the thicker bark 4 having a thickness thicker than that of the conventional bark in the relationship of strength maintenance.

By the way, when the thick thick wood 4 is placed on the upper surface of the strut as in the conventional manner, a step is formed in the top surface of the base 5 of the wood 4.

Advantageously, as shown as a solution to the problem, recesses 6 and 7 having a predetermined depth are provided at the upper edges at which end portions of the cross members of the strut 3 and the outer fabric base 1 are mounted. Engage the lumber end with this recess (6) (7) to connect the lumber (4) between the base fabric (1) and the support (3) and to the foundation (5) and the upper surface of the neighboring support (3) (3). The means for attaching in the same plane state can be taken.

In the embodiment, a form 9 for forming a support 3 having such recesses 6 on both sides of the upper edge thereof is used as an example.

After the form | mold 9 forms the forged concrete pillar 8 as a support body, what is called a support which becomes a part of a support structure as it is is used as a formwork.

As shown in Figs. 1 to 8, the die 9 faces a cylindrical half-section of glass fiber reinforced cement (GRC), that is, a pair of semi-cylindrical dies 9a and 9b facing each other. It is formed in a cylindrical shape by engaging in the cross section.

In other words, engagement portions 10 and 11 each having a male relationship are formed at both end surfaces of the two pieces 9a and 9b.

One engagement portion 10 (hereinafter referred to as a first engagement portion and the other as a second engagement portion) is approximately in plan view. It is shaped and has a convex portion 10a on the inner surface of the base side.

The second engagement portion 11 has a substantially “b” shape on a plane that can be engaged with the first engagement portion 10 in the vertical direction (height), and a recess portion that can engage with the convex portion 10a. Has 11a.

Thus, by slidingly engaging the first engagement portion 10 and the second engagement portion 11 of the two pieces 9a, 9b in the vertical direction, the two pieces 9a, 9b face each other. The cylindrical form 9 is constituted by integrally joining at the end face.

In this formwork state, the two die pieces 9a and 9b are separated from each other by the engagement of the first and second engagement portions 10 and 11 including the convex portion 10a and the recessed portion 11a. Integral relative movement of the radial direction is prevented, thereby firmly joining together, and the adhesion between the two coupling portions is securely maintained.

For this reason, when placing concrete with this form (9a) (9b), the two formwork (9a) (9b) may be separated by concrete pressure, or water may leak out from the joints. none.

In addition, when used in the formwork 9, which is formed of glass fiber reinforced cement, when used as a discarding form as in this embodiment, it has good adhesion with concrete and exhibits the appearance of the concrete itself. There is no such advantage.

In addition, the inner surface of the two formwork (9) is formed in a concave-convex shape as shown in the figure in order to further enhance the adhesiveness with concrete.

In addition, the die pieces 9a and 9b are provided with cutouts 12 and 12 at the upper end portions of the joining portions of the two pieces 9a and 9b, and the above-described end portions of the lumbers are shown in the cutouts 12 and 12 portions. The auxiliary dies 13 and 13 for forming recesses 6 and 6 capable of engaging and retaining are mounted.

This auxiliary formwork 13 is planar, A main body 14 having a bottom shape 14a that is a shape and serves as a transverse support, and a pair of front and rear flange parts 15 and 16 that integrally address the outside of the opening edges on both the left and right sides of the main body 14; The front flanges 15 and 15 are formed in the same plane with the protrusions 17 extending under the main body and mounted on the formwork 9 between the front and rear flanges 15 and 16 on both left and right sides. The sphere 18 is formed.

When the auxiliary dies 13 and 13 are mounted on both side cutouts 12 and 12 of the die 9, as shown in FIGS. 3 and 7, the two side mounting holes 18 of the auxiliary dies 13 are shown. (18) is engaged upstream from both edges of the notches (12) (12).

The width of the mounting holes 18 is smaller than that of the thick part of the die 9, and the mounting holes 18 are cut off by the elasticity (single clamping force) of both flange portions 15 and 16. The auxiliary die 13 is held at an arbitrary height position in the cutout 13 by this elastic engagement force.

The height adjustment action of this auxiliary formwork 13 and the function of the protrusion 17 will be described.

The thickness dimension S ₁ (shown in FIG. 10) of the lumber 4 is actually changed to several according to a building specification.

For example, up to 270mm, four types of 240mm, 210mm, 180mm are used.

On the other hand, the selection 5 usually uses a certain thickness (for example, 105 mm).

Therefore, a holding recess (6), depth dimension (d) of 6 (3) - a (hoengmok thickness S ₁ of the base thickness S ₂₎ have to be changed according to the thickness dimension hoengmok S _1.

As a countermeasure for the advantage, the height of the cutout 12 is different for each depth of the recessed part, while the height of the auxiliary die 13 (the height of the main body 14) is the dimension corresponding to the maximum recessed depth. When the depth is shallow, it is conceivable to cut off the upper excess part of the auxiliary formwork 13.

However, according to this means, the heights of the cutouts 12 and 12 of the formwork 9 must be changed for each recessed depth, which is disadvantageous in manufacturing the formwork 9.

In addition, it is also possible to perform the cut-out 12 on-site according to the depth of the recess, but the construction efficiency is deteriorated and inconsistency in the precision of the dimensions is likely to occur.

In addition, although the cutout 12 can be made into the height dimension corresponding to the maximum depth of the recessed portion, this prevents the leakage of concrete at this opening since the opening of the cutout 12 is formed below the auxiliary formwork when the recessed depth is shallow. There is a need to devise means separately.

Thus, in this embodiment, the cutouts 12 and 12 of the formwork 9 are formed as height dimensions corresponding to the depths of the largest recesses, while the protrusions 17 below the main body 14 of the auxiliary formwork 13. If the depth of the recess is shallow, the opening formed in the lower part of the notch is closed in the protrusion 17 to prevent leakage of concrete.

In this case, since the form | work 9 of the formwork notch is made into a certain kind, the form 9 of the formwork 9 is good, and it is advantageous also in terms of construction and dimension precision.

In addition, the auxiliary die 13 is usually formed of plastic, and is preferably formed of polypropylene which is preferably translucent.

The semi-transparent polyflofilene auxiliary die 13 makes it possible to prevent the occurrence of pores in the concrete when the concrete placing state (filling state) of the concrete is seen from the outside through the cover.

When the struts 3 are formed, as shown in Figs. 2 and 3, the dies 9 formed by joining the constant dies 9a and 9b to a predetermined position on the upper surface of the weight 2 are replaced by the weight 2. It is installed upside down on the reinforcing bar H (shown in FIG. 5), and after the auxiliary formwork 13 and 13 are mounted on the formwork 9, concrete is poured and solidified.

This constitutes a strut 3 having recesses 6 and 6 at the upper edge thereof.

Moreover, 19 of 3rd and 4th degree is a fastener for fixing the lower end part of the formwork 9 to the weight 2.

By the way, this invention is not limited to the said Example, It can change and implement in various states as follows.

1. In the support posts, only the foundation 5 may be mounted orthogonally, in addition to the support post 3 on which the crossbars 4 are mounted as described above. In the case of such posts, the recesses 6 for mounting the crossbars are not required. .

Therefore, what is necessary is just to comprise it as a pair of semi-cylindrical formwork which does not have this recessed part as a pair of semi-cylindrical formwork which does not have the notches 12 and 12 of the said Example.

In this case, of course, the auxiliary formwork 13 is also unnecessary.

The form 9 may be formed in a quadrangular or other cylindrical shape depending on the post shape to be formed.

2. In the above embodiment, the formwork 9 is left to be used as a part of the post even after the concrete is poured. However, the formwork 9 can be removed after the concrete is poured.

3. As the material of the formwork 9, not only the above-mentioned glass fiber reinforced cement (GRC) but also plastics such as vinyl chloride can be used.

4. The shape and structure of the engaging portion for coupling the pair of die pieces 9a and 9b are not limited to those of the above embodiment, and the yaw is relatively relative to both die pieces 9a and 9b in the radial direction. It just needs to be impossible to combine.

Therefore, for example, one engagement portion that can engage with each other may be formed in a pseudo-curve and the other engagement portion in a medical shape, and may be configured to engage this in the vertical direction.

As mentioned above, when the form forming formwork of the present invention is used, the pair of formwork formed by the half-cylindrical form is connected to the cross-sections facing each other so that relative movement is possible only in the direction by the engaging portions of each other. In this case, when the mold is not in use, the formwork can be separated and, for example, in a compact state superimposed in the same direction, so that it is particularly advantageous for mass transport or storage.

In use, two formwork pieces can be engaged up and down at the mating portion, so that they can be easily assembled, and the assembly can be reliably prevented from moving in the direction in which the two piece pieces detach from each other. It is.
