Description

The present invention Oite the plate-shaped insulation material insulation foundation is integrated into the side surface of the foundation, advantageously a line cut to substantially the same plane and the top end face of the top end surface of the foundation a plate-shaped insulation material It relates to ingredients.

  In a building constructed in a cold region, in order to insulate the foundation, a plate-like heat insulating material is integrated along the side surface of the foundation. For example, in the invention described in Patent Document 1, when a foundation is formed, a heat insulating panel is installed in a mold, and concrete is placed in the mold to form a concrete top end face and a heat insulating panel. The top end surface is substantially the same height, and a cement paste leveler is laid with these top end surfaces being continuous. The purpose of this invention is to improve ant resistance, and by laying the leveler continuously on the top end surface of the foundation foundation and the thermal insulation panel, the leveler is filled in the gap between the foundation foundation and the thermal insulation panel. It becomes possible to improve ant resistance.

  In order to insulate the foundation, it is necessary to cover at least one side of the foundation with a heat insulating material without a gap. For example, if the top end surface of the foundation is higher than the top end surface of the heat insulating material, when the floor is constructed on the top of the foundation, a gap is formed between the bottom surface of the floor structure and the top end surface of the heat insulating material, so that the foundation is exposed to the atmosphere. There will be a risk that this gap will constitute a thermal bridge. That is, even in the invention described in Patent Document 1, the leveler laid on the top of the top end face of the heat insulating panel may become a thermal bridge.

  On the other hand, when a plate-like heat insulating material is attached at the same time as the foundation construction, it is very difficult to accurately match the end surface of the heat insulating material with the top end surface of the foundation, leading to fatigue of workers and the work period. There is a risk of extension.

  For this reason, when attaching a plate-like heat insulating material to the side surface of the foundation, the top end surface of the plate-like heat insulating material is previously made higher than the top end surface of the foundation after the self-leveling material is constructed, and integrated. After the applied self-leveling is cured, the plate-like heat insulating material protruding from the top end surface of the self-leveling material is cut and removed using a saw or a knife. However, when cutting a plate-shaped heat insulating material using a knife, it is difficult to make the cut surface (top end surface) of the plate-shaped heat insulating material a flat continuous surface. For this reason, it is common to cut a heat insulating material using a saw.

JP 2003-247282 A

  As described above, if a saw is used when cutting a plate-like heat insulating material integrated on the side surface of the foundation in accordance with the top end surface of the foundation, a large amount of chips are generated and scattered around. . For this reason, after the work environment is deteriorated and the insulating material is cut and removed, there is a problem that the cleaning work resulting from the cutting becomes necessary and the workability is inferior, and even if it is cut with a saw, the cut surface of the plate-like heat insulating material Is not necessarily a flat surface, and when a floor is installed on the upper part of the foundation, there is a possibility that a slight gap is formed between the lower surface of the floor.

An object of the present invention is to provide a wire cutting tool that is advantageous when the top end surface of a foundation and the top end surface of a plate-like heat insulating material are substantially flush with each other.

In order to solve the above problems, a wire cutting tool according to the present invention cuts a plate-like heat insulating material arranged on the side surface of the foundation so that it is flush with or slightly higher than the top end face of the foundation. A linear cutting member, a holding member that holds the cutting member in a thickness direction across a plate-like heat insulating material, and an interval and height that can avoid an anchor bolt protruding from the foundation. are those configured with a pair of moving devices for moving the holding member on the top end face of the foundation.

  In the wire cutting tool according to the present invention, the linear cutting member is held by the holding member while being traversed in the thickness direction of the plate-like heat insulating material, and the height of the cutting member is adjusted by the height adjusting member, and this holding is performed. By moving the member along the top end surface of the foundation by the moving device, the heat insulating material can be set to a desired height from the top end surface and cut.

Further, depending on a pair of mobile device with parallel at a distance and height can be avoided anchor bolts protruding from the foundation, it is moved mobile device placed on the top end surface of the foundation, projecting from the top panel end face The anchor bolt thus made does not become an obstacle to this movement, and a smooth movement can be realized.

  Hereinafter, the preferable form of the wire cutting tool which concerns on this invention is demonstrated.

In order to improve the thermal insulation efficiency of the foundation as much as possible, a part of the foundation (particularly a part near the top end face) is exposed to the atmosphere in the heat insulation foundation constructed using the wire cutting tool according to the present invention. Thus, it is surely prevented from becoming a thermal bridge, and the working environment and workability are improved.

  In the heat insulating foundation, a plate-like heat insulating material (hereinafter referred to as “heat insulating board”) is disposed on the side surface of the foundation and is integrally attached to the foundation. The mounting method for the foundation of the heat insulating plate is not particularly limited, and a conventional method can be employed as appropriate.

  As an example of the above construction method, there is an integral casting method in which a heat insulating plate is arranged in advance inside a mold when constructing a foundation, and the concrete placed on the mold is integrated when solidified. In this construction method, since the heat insulating plate is installed when forming the formwork, the height of the end surface (top surface) of the heat insulating plate can be appropriately set, and the arrangement in the height direction with respect to the top end surface of the foundation The position can be accurately set, which is preferable.

  The heat insulating plate is a heat insulating material formed into a plate shape, and is preferably a plastic heat insulating plate. Examples of such a plastic heat insulating plate include a foamed polystyrene heat insulating plate, a foamed polyethylene heat insulating plate, a foamed urethane heat insulating plate, and a foamed phenol resin heat insulating plate, and any of them can be preferably used.

  However, since the heat insulating plate is cut by a wire cutting tool, it is necessary to adopt a heat insulating plate corresponding to the cutting mechanism of the wire cutting tool. That is, when the wire cutting tool has a mechanism that cuts the heat insulating material with a hot wire whose temperature has been increased, the heat insulating plate is preferably a foamed polystyrene-based heat insulating plate or a foamed polyethylene-based heat insulating plate. Moreover, when the wire cutting tool has a mechanism for cutting the heat insulating plate with a wire through which the solvent is leached, the heat insulating plate is preferably a foamed polystyrene heat insulating plate.

  When the top end surface of the heat insulating plate is slightly higher than the top end surface of the foundation, the value of the height is not particularly limited, considering the elasticity of the heat insulating plate, such as unevenness and lifting of the flooring It is preferable to set appropriately within a range where no trouble occurs. That is, when the flooring is installed on the top end surface of the foundation because the top end surface of the heat insulating plate is higher than the top end surface of the foundation, the bottom surface of the flooring material comes into contact with the top end surface of the insulation plate and compresses and deforms. By making it, it becomes possible to ensure more reliably the contact with the flooring of a heat insulating board, and it is preferable.

The heat insulation foundation construction method using the wire cutting tool according to the present invention is previously attached to the side surface of the foundation so that the top surface (end face) of the heat insulation plate is higher than the top end face of the foundation on which the self-leveling material is constructed. By cutting the heat insulating plate at a position higher than the top end surface of the foundation with a wire cutting tool, the top end surface of the heat insulating plate is made flush with or slightly higher than the top end surface of the foundation.

  In this construction method, there is no limitation as to how high the top surface of the heat insulating plate should be from the top end surface where the basic self-leveling material is constructed. If the difference in height between the two is large, it is possible to proceed the cutting operation in a stable state, but the cut heat insulating material is discarded, which becomes a useless part. If the difference between the two is too small, the wire of the wire cutting tool may be shifted to the top surface side during the cutting operation, and it may be difficult to obtain a good cut surface.

  The wire cutting tool according to the present invention (hereinafter referred to as “cutting tool”) is configured to obtain a top end face that is the same as the top end face of the foundation, or a top end face that is slightly higher than the top end face of the foundation. To cut. For this reason, the linear cutting member is held by the holding member in a state where it is traversed in the thickness direction of the heat insulating plate, and the cutting member is adjusted to a preset height with respect to the top end surface of the foundation by the height adjusting member. In addition, the heat insulating plate can be cut by moving the holding member along the top end surface of the foundation by the moving device.

  As the linear cutting member, it is possible to selectively use a wire for leaching a heat ray or a solvent corresponding to the material of the heat insulating plate to be cut. In particular, a heat insulating plate made of a thermoplastic material can be easily cut by a heat ray with a beautiful cut surface, and such a heat insulating plate preferably uses a heat ray.

  When the cutting member is a heat ray, it is preferably a material that generates heat when energized. In this way, nichrome wire or stainless steel wire can be used as the material of the heat wire, and a battery, a commercial power source, etc. are used as a power source for energizing the heat wire, and a control part is disposed inside the moving device. Is possible.

  The holding member has a function of crossing and holding the linear cutting member in the thickness direction of the heat insulating plate, and the structure is not limited as long as this function can be exhibited. In particular, when the cutting member is a hot wire, it is preferable to have a structure in which a conducting wire that is energized to the hot wire can be wired. Moreover, when the cutting member is a member that allows the solvent to be leached, it is preferable that the container has a structure in which a container containing the solvent can be attached.

  The moving device has a function of moving the holding member holding the cutting member along the top end surface of the foundation, and the structure is not limited as long as this function can be exhibited. In particular, as a method for driving the moving device, an operator may move the device by hand, or an electric motor may be provided to move the device.

  When the holding member holding the cutting member is moved by the moving device to cut the heat insulating plate, in order to ensure the accuracy of the height from the top end surface of the base of the cutting member, the top end surface can be guided as a reference. preferable. The structure of such a guide member is not particularly limited, and a roller may be provided on the holding member and the holding member may be configured to be movable up and down with respect to the moving device. Then, when the roller is brought into contact with the top end surface of the foundation and moved by the moving device, the roller rotates in contact with the top end of the foundation and moves the cutting member along the top end surface of the foundation. Is possible.

  Next, the heat insulation foundation will be described with reference to the drawings. FIG. 1 is a diagram for explaining a heat insulating foundation.

  In the figure, the foundation 1 is composed of a concrete part 1a and a self-leveling part 1b constructed on the top of the concrete part 1a, and the upper surface of the self-leveling part 1b is constituted as the top end face 2 of the foundation 1. ing.

  A heat insulating plate 3 is disposed on the side surface of the foundation 1, and the top end surface 4 of the heat insulating plate 3 is formed on the same surface as the top end surface 2 of the foundation 1 or slightly higher than the top end surface 2. The top end surface 4 of the heat insulating plate 3 is constituted by a cut surface obtained by cutting the top surface (end surface) 3a side of the heat insulating plate 3 attached to the side surface of the foundation 1 by a cutting tool line 5 (for example, a heat ray) indicated by a two-dot chain line. Has been.

  In this heat insulating foundation, since the top end face 2 of the foundation 1 and the top end face 4 of the heat insulating plate 3 are the same surface or the top end face 4 is formed slightly higher than the top end face 2, as shown in the figure, the foundation 1 When the floor panel 6 is disposed on the floor, no gap is formed between the floor panel 6 and the heat insulating plate 3, and the gap does not become a thermal bridge and the heat insulation efficiency does not deteriorate.

Next, the construction method of a heat insulation foundation is demonstrated using figures. FIG. 2 is a diagram for explaining the procedure of the construction method. In the figure, the same reference numerals are given to the same parts and parts having the same functions as those in the above-described example, and the description thereof is omitted.

  As described above, it is possible to attach the foundation and the heat insulating plate in an integrated manner by placing a heat insulating plate in the mold in advance and placing concrete in the mold.

  In this example, the heat insulating plate 3 is previously arranged inside the mold 8 so that the heat insulating plate 3 can be integrated with the side surface of the base 1 simultaneously with the construction of the base 1.

  First, as shown in FIG. 2A, the mold 8 is installed and the heat insulating plate 3 is arranged inside the mold 8. At this time, the heat insulation board 3 is arrange | positioned so that the end surface 3a may become higher than the top end surface 2 of the foundation 1 preset.

  Thereafter, as shown in FIG. 2B, concrete is placed on the mold 8 to form the concrete portion 1a. After the concrete portion 1a is hardened, a self-leveling material is poured into the concrete portion 1a to make self-leveling. The base 1 having the horizontal top end surface 2 is formed by forming the portion 1b, and the heat insulating material 3 is integrated and attached to the side surface of the base 1 at the same time.

  After the foundation 1 is cured, the mold 8 is removed, and a portion 5 higher than the top end surface 2 of the foundation 1 in the heat insulating plate 3 is disposed on the heat insulating plate 3 as shown in FIG. Disconnect by. When the cutting with respect to the heat insulating plate 3 is completed, as shown in FIG. 4D, the heat insulating base 3 has the top end surface 4 that is flush with the top end surface 2 of the base 1 or slightly higher. Is configured.

In the above construction method, when the heat insulating plate 3 higher than the top end surface 2 of the foundation 1 is cut, it is cut by the wire 5, so that no chips are generated and the work environment is not deteriorated. Moreover, since the top end surface 4 is the same surface as the top end surface 2 or at a slightly higher position, no gap is formed on the lower surface of the floor panel even when the floor panel is disposed on the foundation 1.
[ Comparative Example 1 ]

Next, a comparative example of the cutting tool according to the present invention will be described with reference to the drawings. FIG. 3 is a schematic diagram illustrating the configuration of a cutting tool that cuts the heat insulating plate while moving along the surface of the heat insulating material.

  In the wire cutting tool of this example, the moving device is configured to move by bringing a roller into contact with the surface of the heat insulating plate attached to the side surface of the foundation. Thus, the smooth movement based on the surface of a heat insulation board is realizable by being constituted so that a movement device may make a roller contact the surface of a heat insulation board, and can move.

  The cutting tool A shown in the figure includes a case 10 that is a moving device having a rectangular cross section, a plurality of rollers 11 that are arranged on two orthogonal surfaces 10a and 10b of the case 10, and a substantially roller that is a holding member. The arm 12 is formed in a letter shape so as to be upright and rotatable from the end surface 10c of the case 10, and the heat wire 5 is attached to the arm 12 and serves as a cutting member.

  The cutting tool A of this example is configured so that an operator can hold and operate it by hand. For this reason, it is preferable to form the case 10 into a shape suitable for an operator to hold and operate, or to provide a handle (not shown).

  The case 10 accommodates a power source such as a battery or a commercial power source for energizing the hot wire 5, and a switch (not shown) for energizing the hot wire 5 or stopping the energization on the surface. A knob (not shown) for adjusting the energization voltage is arranged.

  Two rollers 11 are arranged on each of the two surfaces 10a and 10b of the case 10, and the rollers 11 arranged on the surfaces 10a and 10b rotate while contacting the outer surface of the heat insulating material 3, thereby 12 (heat wire 5) is moved. The length of the roller 11 does not have to extend over substantially the entire length of the case 10 as in this embodiment, and two rollers 11 may be arranged at both ends in the longitudinal direction of the case 10. In this case, the roller 11 is not preferably a so-called free roller, and is preferably a roller having a fixed rotational direction. By using such a roller, the moving direction of the heat ray 5 does not inadvertently deviate from the top end surface 2 of the foundation 1.

  The arm 12 has a function of holding the heat ray 5, and includes an upright part 12 a erected from the end surface 10 c of the case 10, a horizontal part 12 b formed in the horizontal direction from the end part of the upright part 12 a, and a horizontal part 12 b. And a hanging portion 12c hanging from the end portion. The arm 12 is formed of a cylindrical body, and a conducting wire for energizing the heat wire 5 is wired inside. And the terminal 13a, 13b is each provided in the position facing the lower end part of the hanging part 12c, and the lower end part of the hanging part 12c of the standing part 12a, and connects the edge part of the heat wire 5 to these terminals 13a, 13b. Thus, the heat wire 5 can be energized.

  The length of the hanging portion 12c is set shorter than the length of the standing portion 12a. When the heat wire 5 is connected to the terminals 13a and 13b, the heat wire 5 is positioned on the same surface as the lower end surface 12d of the hanging portion 12c. Is configured to do.

  The upright portion 12a of the arm 12 is rotatably and fixedly attached to an attachment portion 14 provided on the end surface 10c of the case 10. A set screw 14a is screwed to the mounting portion 14, and by loosening the set screw 14a, the arm 12 can rotate at a desired angle around the upright portion 12a, and is rotated at a desired angle. The arm 12 can be fixed by tightening the set screw 14a.

  By configuring the arm 12 as described above, for example, when the heat insulating plate 3 disposed at the corner of the foundation is cut, the rollers 11 provided on the two orthogonal surfaces 10a and 10b are simultaneously brought into contact with each other. In this state, by rotating the arm 12 approximately 90 degrees, the heat insulating plate 3 attached to the base 1 in the other direction with the heat wire 5 traversed in the thickness direction with respect to the heat insulating plate 3 attached to the base 1 in one direction. It is possible to cross in the thickness direction. Therefore, by moving the case 10 in this state, it is possible to cut the heat insulating plate 3 arranged in the other direction.

  The horizontal portion 12b of the arm 12 has a dimension sufficiently larger than the thickness of the heat insulating plate 3 to be cut. Moreover, the length of the hanging piece 12c has a dimension larger than the height which protrudes from the top end surface 2 of the foundation 1 of the heat insulation board 3 attached to the side surface of the foundation 1.

  The guide member 15 has a bracket 15a composed of a horizontal piece 15b and a protruding piece 15c, and two rollers 15d having rotation axes parallel to the arrangement direction of the heat rays 5 at both ends of the horizontal piece 15b of the bracket 15a. Is rotatably mounted. A long hole (not shown) is formed in the upright piece 15b of the bracket 15a or the hanging portion 12c of the arm 12, and the bracket 15a is fixed at a desired position by using a bolt 15e. It is possible to adjust the height from. Further, when cutting the heat insulating plate 3, the heat ray 5 can be guided along the top end surface 2 by always rotating the roller 15 d in contact with the top end surface 2.

  In the cutting tool A configured as described above, the position of the guide member 15 is adjusted in accordance with the heights of the top end surface 4 of the heat insulating plate 3 and the top end surface 2 of the foundation 1 set in advance. That is, the bolt 15e constituting the guide member 15 is loosened and the bracket 15a is moved up and down along the hanging portion 12c to adjust the distance between the line connecting the two rollers 15d and the heat wire 5. When this adjustment is completed, the bolt 15d is tightened to fix the bracket 15a to the hanging portion 12c.

  Next, the switches provided on the case 10 are operated to energize the hot wire 5 to raise the temperature. When the hot wire 5 rises to an appropriate temperature, the worker grips the case 10 and lowers the roller 11 in contact with the surface of the heat insulating plate 3, and in this process, starts cutting from the end 3a by the hot wire 5. To do. As the case 10 further descends, the roller 15d constituting the guide member 15 provided on the hanging portion 12c of the arm 12 contacts the top end surface 2 of the foundation 1.

  When the roller 15d of the guide member 15 is in contact with the top end surface 2 of the foundation 1 while maintaining contact of the roller 11 provided on the case 10 with the surface of the heat insulating plate 3, the heat ray 5 crosses the heat insulating plate 3 in the thickness direction. In addition, the height from the top end surface 2 becomes a preset height. The heat insulating plate 3 can be cut by moving the case 10 in a desired direction while maintaining this state, and the top end surface 4 is formed by the cut surface.

For example, the cutting of the heat insulating plate 3 attached to the unidirectional foundation 1 constituting the corner is finished, and the roller 11 provided on the surface in the direction orthogonal to the heat insulating plate 3 comes into contact with the heat insulating plate 3 in the other direction. When this contact state is maintained and the set screw 14a provided on the mounting portion 14 is loosened, the arm 12 is rotated approximately 90 degrees to cut the corner portion of the two-way heat insulating plate 3 arranged at the corner. At the same time, the heat insulating plate 3 in the other direction is traversed in the thickness direction. Then, the arm 12 is fixed by tightening the set screw 14a, and the roller 11 provided in the case 10 in this state is moved in contact with the surface of the heat insulating plate 3 in the other direction, so that the two directions straddling the entering corner are moved. It is possible to cut the heat insulating plate 3 smoothly.
