Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a formwork material used for placing concrete, and more particularly, to a formwork constructed using the formwork material and a method of assembling the formwork using the formwork material.
[0002]
In the conventional formwork, the four-sided formwork panels are arranged side by side on one side to assemble into a wall form, and are arranged at predetermined intervals on the other side in the same manner as the wall form. The formwork panel is fixedly held by a separator arranged between these opposed formwork panels. Thereafter, fluid concrete is poured between the forms, and after the consolidation, the form panels are removed. Alternatively, if the formwork panel also serves as a decorative material having its outer surface coated, it is directly buried.
In any of the above-described formwork constructions, installation of the separator requires time and is a bottleneck in the construction together with the stacking accuracy of each formwork panel.
In addition, since the end of the separator protrudes from the surface of the formwork panel, it is necessary to cut the separator afterwards in the case where the formwork is removed, and to fill the formwork. In that case, the exposed ends of the separator impair the aesthetic appearance.
Further, according to the quadrilateral panel, the wall plate obtained by joining the quadrilateral panels is subjected to the horizontal force along the side of the quadrilateral panel due to the plate force acting in the plate surface direction of the plate. There is only a component force in two directions, the direction and the vertical direction, and the force is not concentrated, and it is difficult to obtain the convergence and concentration of the acting force at the intersection where the corners of each panel are gathered. This is likely to cause loosening from the resection site, causing overall breakage.

The dimensional relationship between the wedge groove and the wedge bar on the oblique side is equal to that of the short side of the entire size base 1.
[0015]
Assembling of the formwork The formwork construction performed using the formwork material K of the present embodiment will be described.
6 and 7 show an example of the construction mode. The circled numbers (1), (2), (3),... In the figure indicate the order of construction.
[0016]
(1) A foundation H is constructed, and wedge rods 2 for oblique sides are installed on the upper surface of the foundation H at predetermined intervals. At the end, a wide vertical member V extending between two molds is installed. The vertical material V prevents the concrete poured later from flowing out.
[0017]
(2) After that, assemble the formwork in the following procedure. In principle, the formwork is placed relative to the formwork space α and assembled with the same phase.
{Circle around (1)} The oblique side 1d of the first substrate 1 arranged at the end is fitted into the wedge bar 2B of the foundation H and built. The wedge bar 2A is fitted into these short sides 1c.
(2) The half-size substrate 1A is built along the vertical material V.
{Circle around (3)} The substrate 1 is built in such a manner that its oblique side 1d is fitted into the wedge bar 2B side by side with the substrate 1 installed earlier. The wedge bar 2A is fitted into these short sides 1c.
{Circle around (4)} The substrate 1 is dropped and built with its right-angled portion A down. A wedge bar 2B is fitted into the hypotenuse 1d.
{Circle around (5)} The separator 3 is placed between the notch concave portions 5 which are opposed to each other.
(6) The substrate 1 is built next to the substrate 1 set in (3). The wedge bar 2A is fitted into the short side 1c.
{Circle around (7)} The substrate 1 is built with the right-angled portion A facing downward.
(8) The separator 3 is installed.
After the installation of the separator 3 in (8), the right portion of the substrate 1 in (6) in the figure is thereafter appropriately made according to the above procedure.
(9) The separator 3 is installed.
(10) At the end, the half-size substrate 1A is erected along the vertical material V. Fit the wedge bar 2A.
(11) The substrate 1 is built. The wedge bar 2A is fitted into the short side 1c.
(12) The substrate 1 is built. The wedge bar 2A is fitted into the short side 1c.
(13) The substrate 1 is built with the right-angled portion A facing downward. The wedge bar 2B is fitted into the hypotenuse 1d.
(14) The substrate 1 is built with the right-angled portion A facing downward. The wedge bar 2B is fitted into the hypotenuse 1d.
(15) The substrate 1 is built with the right-angled portion A facing downward. The wedge bar 2B is fitted into the hypotenuse 1d.
(16) The separator 3 is installed.
(17) The separator 3 is installed.
Hereinafter, it is assembled rightward according to the above procedure, and further assembled upward.
[0018]
(3) When the formwork opposed to the predetermined formwork space α is assembled, the concrete C is cast and the solidification is awaited. The separator 5 opposes the fluid pressure and does not cause abnormal swelling of the plate.
The formwork remains buried and forms a solid wall with the internal concrete. In the case where the surface 1a of the substrate 1 is provided with a makeup, the makeup 1 is used as it is on the outer wall of the makeup without any trouble of performing the makeup.
[0019]
In this formwork, the oblique side 1d of the substrate 1A always assumes a horizontal state. The separator 3 is installed when the lower substrate 1 is kept horizontal (180 °) in the intersection T portion. That is, at this time, the cutout concave portions 5 formed by the three lower substrates 1 have a semicircular shape that opens upward.
The installation of the wedge bar 2 on the foundation H is not always necessary. The form substrate 1 may be set up on the foundation H.
[0020]
According to the assembling and construction of the formwork, there are only two types of operations, a standing operation performed with the oblique side 1d of the form substrate 1 facing downward and a dropping operation performed with the right angle portion A facing downward. Therefore, the work is easy. In particular, when the substrate 1 is dropped into the triangular space, the work can be performed with a sufficient amount of space, the positioning can be easily performed by the guide action of the inclined surface 4b of the wedge groove 4, and the parallelism of the conventional rectangular plate can be maintained. There is no complexity (skill level) to assemble.
During this time, the separators 3 are sequentially installed, and the positioning operation is performed automatically and accurately. In addition, the separator 3 is not exposed on the surface of the mold to be constructed, and contributes to a beautiful finish.
In this embodiment, the wedge bar 2A is attached to the existing substrate 1 when the substrate 1 is dropped, but the wedge bar 2A may be attached to the substrate 1 to be dropped and assembled.
In the assembling work of the formwork, the formwork substrate 1 is concentrated toward the center in the intersection section T, so that the automatic centripetal action works and a precise formwork is assembled.
In the assembled formwork, as shown in FIG. 8, in the intersection portion T, the force f1 is obliquely applied while maintaining the symmetry, and is tightened by the wedge effect. Bond is made, and large strength is exhibited. Although the line of action of the force is directed to the center O of the intersection T, the transmission of the force is performed at the contact surfaces (2a and 4b) between the wedge bar 2A and the wedge groove 4A, and the forces are equalized. In other words, stress concentration on the center O of the intersection T is avoided. In the figure, f0 is a horizontal component force.
The intersections T are evenly distributed on the entire surface of the mold, and exhibit a large strength as a whole.
[0021]
In the case where the form plates on both sides receive a leaning load during the assembling of the formwork, it is possible to effectively prevent the falling down by increasing the diameter of the connecting rod 13 of the separator 5. it can.
[0022]
(Another aspect)
In the above embodiment, the cross section of the wedge groove 4 of the substrate 1 is rectangular, and the cross section of the wedge rod 2 is correspondingly rectangular. It does not exclude other shapes that are attached.
FIG. 9 shows an example of this mode.
(A) The figure shows a wedge bar 15 of circular cross section. Correspondingly, the substrate 1 has a wedge groove 16 having a semicircular cross section.
(B) The figure shows a wedge bar 17 with a rhombic cross section. Correspondingly, the substrate 1 is formed with a wedge groove 18 having a triangular cross section.
(C) The figure shows a wedge bar 19 of octagonal cross section. Correspondingly, the substrate 1 has a wedge groove 20 having a half-octagonal cross section.
FIG. 10 shows another embodiment of the separator portion.
The separator 3A of the present embodiment includes an octagonal flange 22 and an octagonal connecting rod 23. Correspondingly, the large-diameter concave portion 6 and the small-diameter concave portion 7 of the notch concave portion 5 also take an octagonal shape. In addition, the quadrangular shape is not excluded.
[0023]
The size of the formwork substrate 1 is not particularly limited, but it is a guide that the formwork substrate 1 can be transported manually. However, if the mechanical force of a crane or the like can be applied, the size can be further increased. Accordingly, the sizes of the wedge bar 2 and the separator 3 are also determined.
[0024]
FIG. 11 shows another embodiment of the form material. In the figure, the same reference numerals are given to members equivalent to those in the above embodiment.
The mold substrate 1A of the mold material K1 has a regular triangular shape, and has cutout recesses 5 (large-diameter portion 6, small-diameter portion 7) similar to those of the previous embodiment at the corners. A wedge groove 4B similar to the previous embodiment is formed on the side corresponding to the bottom 1d of the substrate 1A. The corresponding wedge bar 2B is the same as in the previous embodiment. Note that these wedge grooves 4B and wedge rods 2B can be omitted.
In this embodiment, the wedge groove 4C recessed on the other two sides 1c is unique to this embodiment, and the inclined surface at one end is set to 60 ° and the inclined surface at the other end is set to 30 °. The wedge bar 2C corresponding to this is also unique, and the corner portion at the tip is formed of two types of inclined surfaces of 60 ° inclination and 30 ° inclination. Note that 60 ° and 30 ° of these ends include less than 60 ° and less than 30 °, respectively.
The assembling work of the formwork performed using the formwork material K1 is performed in the same procedure as described in the previous embodiment, and the separator 3 is used earlier.
[0025]
The present invention is not limited to the above embodiment, and various design changes can be made within the scope of the basic technical concept of the present invention. That is, the following embodiments are included in the technical scope of the present invention.
{Circle around (1)} The shape of the mold substrate 1 is a right-angled isosceles triangle, but a slight length in the short side portion 1c is allowed. However, in this case, it is essential that they have the same shape.
Further, the form substrate 1 may include other right triangles. That is, it is permissible to make the short sides (two sides sandwiching the right angle) up to a ratio of about 2: 1. Of course, the end angle of the wedge bar 2 is also changed correspondingly. Also in this case, it is essential to use the same substrate 1.
[0026]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to this invention, a mold is assembled | assembled only with three standardized constituent materials, there is no other member used, and the manufacturing cost of a mold construction can be reduced sharply. In addition, since it is made up of a combination of triangular form substrates, the action of diagonal forces in addition to the horizontal and vertical directions is added, and the force concentrates toward the intersection where the corners of the board gather, and the tightening action As a result, a formwork body without slack is constructed.
Engagement of the wedge bar with the wedge groove equalizes this concentration of force at that location. The engagement of the wedge bar with the wedge groove also serves as a guiding action in the mounting operation of the substrate.

In particular, when the substrate is dropped into a triangular space, the work can be performed with a sufficient amount of space, and the positioning can be easily performed by guiding the inclined surface of the wedge groove. There is no.
During this time, the separators are sequentially installed, and the positioning operation is performed automatically and accurately. In addition, the separator is not exposed on the surface of the formwork to be built, and contributes to a beautiful finish. By increasing the diameter of the connecting rod of the separator, the compression resistance can be exhibited.
In the assembling work of the formwork, since the formwork board is concentrated toward the center in the intersection, the automatic centripetal action works, and a precise formwork is assembled.
