Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an improvement of a device for attaching a metal formwork and a heat insulating material used in a concrete foundation insulation method in cold regions.

Prior Art and Problems In cold regions, as shown in Figure 5, a heat insulating material 7' is installed on the outer or inner surface of the concrete foundation C to prevent cold damage during the cold season.

The sixth insulation method for installing this insulation material is
A heat insulation method using a concrete panel formwork 1' as shown in FIG. 7 is widely known.

The insulation construction method shown in Figure 6 involves adding a heat insulating material 7' to the mold surface of one concrete panel formwork 1', and abutting a washer 5' to the nail driving surface side of the insulating material 7'. A nail 3' is driven into the insulation material 7' and one concrete panel formwork 1' through the washer, and the insulation material 7' is attached to one concrete panel formwork 1'.
When the concrete poured between the other concrete panel formwork 1' and the insulation material 7' hardens,
One and the other concrete panel formwork 1' were removed, and a concrete foundation c was constructed with a heat insulating material 7' installed on the form surface. (a→b→c).

The insulation method shown in Figure 7 uses a separator 3', and attaches the other concrete panel formwork 1' to one end of the separator with a P cone 5', and attaches a jointer 5 to the other end of the separator. 5'' to the insulation material 7' attached to one side of the concrete panel formwork 1'.
After touching the concrete panel formwork 1' and the insulation material 7', pass the bolts 5 from the insulation material side and the opposite side, screw them into the jointer 5'', and attach the insulation material 7' to one of the concrete panels. It is attached to one side of the panel formwork 1'.Concrete is poured between the other concrete panel formwork 1' and the insulation material 7', and when the concrete hardens, the P connector 5' remains attached. The other concrete panel formwork 1' and one concrete panel formwork 1' with the bolts 5 still attached were removed, respectively, and a concrete foundation c was constructed with a heat insulating material 7' installed on one side. (a→b→c).

When using the former of these insulation methods, the material of the concrete panel formwork 1' is a metal plate (thickness 1.2
~1.6mm steel plate), nailing is not possible, so
It cannot be used in all insulation methods that use metal formwork. In addition, in the case of the latter, if the material of the concrete panel formwork 1' is a metal plate (same as above), due to the strength of the separator 3', the separator is used to connect the insulation material 7' to the concrete panel. It is not possible to adopt the construction method of attaching it to the manufacturing formwork.

The present invention was developed by focusing on these problems.In the concrete foundation insulation method using metal formwork, the insulation material can be easily attached to the metal frame plate, and the metal formwork can be dismantled smoothly. The purpose of the present invention is to propose a device for attaching metal formwork and heat insulating material, which can maximize the shortening of the construction period of the concrete foundation insulation method using metal formwork.

Means for solving the problem The present invention involves drilling an appropriate number of insertion holes in the metal formwork,
A locking part is provided at one end of the spring material that is passed through the insertion hole, the spring material is passed through the elastic mounting hole of the locking plate, and the heat insulating material attached to the back surface of the metal formwork is A method is proposed in which a locking portion of a spring material penetrated through the insertion hole is inserted and locked, and a locking plate is crimped onto the surface of the metal formwork.

Effects of the invention Since the present invention consists of the above-mentioned means, it eliminates the worry that the locking part of the spring material that is stuck to the insulation material will easily come off during construction, and the locking plate is crimped to the metal formwork. This eliminates the need for the insulation material to separate from the metal formwork.

Therefore, the heat insulating material can be attached to the metal formwork with a simple installation method that requires no effort, such as piercing and locking the spring material to the heat insulating material and crimping the locking plate to the metal formwork, allowing efficient insulation in a short time. This has the effect of allowing materials to be attached to metal formwork. After the poured concrete has hardened, the metal formwork through which the spring material has not penetrated is dismantled using the usual method, and the metal formwork through which the spring material has penetrated is secured. The dismantling work of the metal formwork can be easily completed by separating the board from the insulation material using an appropriate tool. Therefore, a concrete foundation for cold regions equipped with a heat insulating material can be efficiently constructed in a short time. Therefore, the characteristics of the insulation method using metal formwork in cold regions can be maximized.

Embodiment To explain an embodiment of the present invention with reference to the drawings, a metal formwork 1 is a formwork made of, for example, a steel plate, and is constructed by drilling an appropriate number of insertion holes 2 at regular intervals in advance on one side. A heat insulating material 7 is attached. Insertion hole 2 is 2 to 5
The hole has a diameter of about mm, and is used for inserting the spring material 3, as well as for draining water from poured concrete. The spring material 3 is a spring wire material with a diameter of about 0.4 to 1.5 mm (for example, piano wire, hard steel wire, stainless steel wire for springs, other spring wire materials, Fig. 3a,
b, c, and e), and is a thin rod having moderate elasticity (see Fig. 3 d), and has a locking part 4 at one end so that it can be pierced and locked into the heat insulating material 7. do. The other end of the spring material 3 is bent as necessary,
The penetrating locking plate 4 is configured to prevent it from falling off and to prevent it from piercing the body or clothes. The spring material 3 was selected for attaching the heat insulating material 7 because when it is inserted into the insertion hole 2 of the metal formwork 1 and the heat insulating material 7, the spring material 3 bent at the locking portion 4 pierces the heat insulating material 7. This is to take advantage of the fact that the spring material 3 returns to its original state due to its elasticity after it has passed through the insulation material 7, and the spring material 3 that has passed through the insulation material 7 is
returns to its original position due to its elasticity, bites into the heat insulating material 7, and locks in place. When the locking part 4 is integrally formed in a ring shape by folding one end of the spring material 3 over 180 degrees (see Fig. 3a),
When a chevron-shaped locking piece is fixed to one end of the spring material 3 (see Fig. 3b), when a cone-shaped locking piece is fixed to one end of the spring material 3 (the third (see Figure c), when both sides or one side of one end of the spring material 3 are formed into a notched shape to form an integral structure in the form of a figure-of-eight wing (see Figure 3 d), a locking jaw is attached to one end of the spring material 3 on the side. In the case where the spring material 3 is integrally constructed by protruding toward the direction, and the locking portion side is bent at right angles to form the spring material 3 into a substantially L-shape (see Fig. 3 e), a V is formed at one end of the spring material 3.
Various structures can be considered, such as one constructed by fixing a letter-shaped locking piece. Among these, the locking part 4 shown in FIG. 3e has the spring material 3 formed in a substantially L-shape, so when it pierces the heat insulating material 7, it is parallel to the spring material 3 as shown by the imaginary line. Also, when locking the insulation material 7, the spring material 3 is deformed in a straight line due to its elasticity in order to pull the spring material 3 in the opposite direction to the insertion direction, and the locking portion 4 is connected to the spring material 3. It becomes orthogonal and is locked to the heat insulating material 7. The locking plate 5 is a locking portion 4 of the spring material 3.
This member is used to maintain the locked state between the heat insulating material 7 and the heat insulating material 7 and bring the heat insulating material 7 into close contact with the metal formwork 1. It is made of elastic polymer materials (for example, synthetic resins, celluloid, natural rubber, synthetic Rubber, etc.), spring plate materials (e.g., stainless steel strips for springs, cold rolled steel strips for springs, other steel strips for springs, etc.) are formed into an appropriate shape, and the appropriate parts such as the center or both ends are A mounting hole 6, which may or may not have elasticity, is formed to allow the spring material 3 to pass through.
As an example of drilling an elastic mounting hole 6, when using the intersection of cross-shaped elongated holes as the mounting hole 6 (see Fig. 4 a and c), the locking plate 5 can be used as a horizontally elongated H-shaped elongated hole. When drilling the mounting hole 6 in the hole (Fig. 4 g, h
), the mounting holes 6 may be drilled at both ends of a spring plate bent into an arched shape, or in the center of a spring plate bent into a shape (17) (see Fig. 4 f).
In the case of these configurations, elasticity is imparted to the mounting hole 6 by the elasticity of the elastic piece 501 constituting the mounting hole 6 or the spring plate material itself, and it becomes difficult to return the mounting hole 6 when it is mounted to the spring material 3. As an example of drilling a non-elastic mounting hole 6, the locking plate 5 is used when drilling a straight-shaped mounting hole 6 in a spring plate material (Fig. 4 b, d).
In this case, the width of the mounting hole 6 is made slightly shorter than the diameter of the spring material 3 to make it difficult to return due to friction with the spring material 3 passed through the mounting hole 6.
Furthermore, as an example of drilling an inelastic mounting hole 6 in the locking plate 5, the mounting hole 6 may be formed in the center of the bottom plate of a spring member bent into a substantially triangular shape.
In this case, the spring material 3 passed through the mounting hole 6 is pinched by the elasticity of the spring plate material itself, making it difficult to return. As described above, the locking plate 5 is configured so that it is difficult to return to the original position after being moved, so that it is difficult to return to the original position after being crimped onto the metal formwork 1.
and the heat insulating material 7 is maintained.
The locking plate 5 is a non-porous rubber plate (3 to 6 mm thick).
), the spring material 3 can be pierced, so it can be used as is. (See Figure 4 i, j). The heat insulating material 7 is made of foamed synthetic resin (for example,
After attaching a commercially available product (trade name: Styrofoam, etc.) to one side of the metal formwork 1, the spring material 3 is pierced, the locking part 4 is locked, and the locking plate 5 is crimped to the metal formwork 1. By tightening it, it is brought into close contact with the metal formwork 1.

Next, the installation method of the metal formwork 1 and the heat insulating material 7, which brings the heat insulating material 7 into close contact with the metal formwork 1, is outlined in FIG. 2.
The locking portion 4 side is penetrated, and the locking portion side is directly pierced through the heat insulating material 7, and the locking portion 4 is made to protrude from the heat insulating material 7. Next, the spring material 3 is pulled in the direction opposite to the insertion direction, and the locking portion 4 is locked to the heat insulating material 7. At this time, the locking part 4 bites into the heat insulating material 7 and locks while being slightly deformed. When the locking part 4 is locked to the heat insulating material 7, the locking plate 5 through which the spring material 3 passes is moved and pressed to the metal formwork 1, and the heat insulating material 7 is brought into close contact with the formwork.

Thus, the installation method is completed and the construction of a concrete foundation is started using the other metal formwork 1 without the insertion hole 2.

When the poured concrete for the concrete foundation has hardened, one metal formwork 1 is separated from the heat insulating material 7 with the locking plate 5 using a suitable tool, and the other metal formwork 1 without the insertion hole 2 is hardened. If it is separated from the concrete by a conventional method, a concrete foundation with a heat insulating material 7 installed on one side is completed.
(See Figure 2 a → b → c, Figure 5 a, b).
