It relates to a highly heat-insulating foundation structure.

  Conventionally, there are underfloor heat insulation and basic heat insulation as technologies aiming to obtain a heat insulation effect under the floor of a building. Under-floor heat insulation is a method in which a heat insulating material is additionally applied to the back side of the floor. Usually, a ventilator under the floor is sometimes installed to improve the ventilation under the floor. On the other hand, the foundation heat insulation is a method of heat insulation using the foundation itself made of concrete of the building, and the foundation itself is covered with a heat insulating material to block the underfloor space from outside air.

  For example, Japanese Patent Application Laid-Open No. 2008-144370 discloses a technology related to a heat insulation structure outside a foundation in which a heat insulating material and an exterior material are laminated on the outside of a foundation rising portion standing on the ground, and the exterior material adjacent in the horizontal direction. It has been suggested that it is possible to provide a basic heat insulating structure that has good durability and excellent maintainability because the structures are connected with each other in a loose structure.

  According to this method, it is possible to construct a foundation heat insulating structure that is durable and easy to maintain, but since the heat insulating material is installed by a method of directly sticking to the foundation with an adhesive etc. after the foundation construction, There was a problem that it took time to build the foundation. Moreover, it is possible to obtain a reliable heat insulating effect by bringing the heat insulating materials into close contact with each other, but according to the invention, it cannot be said that the heat insulating materials can be reliably brought into close contact with each other.

  The applicant of the present invention is the inventor of Japanese Patent No. 3899493 (Japanese Patent Laid-Open No. 2007-224542), Japanese Patent No. 3941831 (Japanese Patent Laid-Open No. 2007-270599), and Japanese Patent No. 4058702 (Japanese Patent Laid-Open No. 2008-184825). And a patent holder. In Japanese Patent No. 3899493 (Japanese Patent Laid-Open No. 2007-224542), both heat insulating materials are provided by a heat insulating foundation that can surely prevent timber (base, etc.) of a building on the foundation from being damaged by termites, and by the pressure of cast concrete. Techniques have been disclosed for a method for constructing a heat insulation foundation that can prevent breakage due to collapsing and improve linear accuracy.

  Patent No. 3941831 (Japanese Patent Application Laid-Open No. 2007-270599) is a heat insulation base that can quickly and firmly connect a heat insulation block and can provide an anchor bolt at an accurate position and posture. The technique regarding the heat insulation foundation which can perform installation of swiftly is disclosed.

Furthermore, in Japanese Patent No. 4058702 (Japanese Patent Laid-Open No. 2008-184825), the inner heat insulating member can be quickly and easily thrown away from the concrete without the need for post-processing, and can be installed, and the inner heat insulating member and the outer heat insulating member are formed. The technology regarding the heat insulation foundation which can perform the connection operation | work of the heat insulation block to perform rapidly is disclosed.
All of these inventions are designed to construct a heat insulating foundation by pouring concrete into a frame formed of a heat insulating member after installation of the heat insulating member. It can be said that it can be secured.

  In these conventional inventions, in constructing a heat insulation foundation, a heat insulation block is installed in the foundation portion in advance and concrete is poured, but the heat insulation block is made of a flexible material such as polystyrene foam. Therefore, if there is a gap at the joint between the heat insulating blocks when pouring the concrete, the concrete may flow out from there. If the foundation was formed in this state, there was a possibility that a sufficient heat insulation effect could not be obtained, and furthermore, there was a possibility that a problem would occur in the strength of the foundation of the building. This is considered to be because the bonding strength between the heat insulating blocks is not sufficient.

Therefore, development of a heat insulating block and a structure that forms a heat insulating base, which solves the above problems, has high bonding force between the heat insulating blocks, has rigidity and heat insulating properties, and has been desired.

  The heat insulation block 10 of the present invention is composed of a block main body 20, a connection plate 30, and a connecting rod 40, and the block main bodies 20 are fixed to each other by a connecting rod 40 penetrating the connection plate 30, whereby a plurality of The heat insulation block is connected.

  As shown in FIG. 1, the heat insulating block 10 has a configuration in which a plurality of connection plates 30 are embedded in the block main body 20, and end portions of the connection plates 30 protrude from both longitudinal ends of the block main body 20. The heat insulating blocks 10 can be joined to each other, and the two heat insulating blocks 10 are fixedly connected by penetrating the connecting rod 40 (see FIG. 3A) into the through hole 32. In other words, the protruding portions of the connection plate 30 of the heat insulation block 10 are attached to each other. The connection plate 30 is provided with a through-hole 32, and the protruding portions of the connection plates 30 of adjacent blocks are overlapped with each other to form one through-hole 32 formed by overlapping two continuous plates. The heat insulating block 10 is connected and fixed by passing through the connecting rod 40.

  The block main body 20 is a block body used for the foundation of a building having a heat insulating effect, and also serves as a mold for sandwiching the concrete of the foundation. The block body 20 is a material having a heat insulating effect and needs to be a material having durability against changes in humidity and temperature and aging deterioration.In this embodiment, a foamed synthetic resin is used. If it is a heat insulating and durable material, it can be used in place of the foamed synthetic resin.

  As shown in FIG. 2, the connection plate 30 is a plate-like member in which through holes 32 through which the connecting rod 40 penetrates are formed at both ends, and is embedded in the block body 20. As will be described in detail below, the length of the connection plate 30 is formed to a length corresponding to the block main body 20 so that the through hole 32 is located at a position protruding outside the block main body 20. The connection plate 30 is a member provided for connection between the heat insulation blocks 10 and is required to have durability against humidity and temperature over a long period of time. In this embodiment, a steel material such as stainless steel is used. It is not limited to. Moreover, although the shape of the through hole 32 is elliptical in the present embodiment, the shape of the hole can be changed as appropriate.

  The connecting rod 40 has the outer shape shown in FIG. 3A, and as shown in FIG. 6, the connecting rod 40 is a member that connects the heat insulating blocks 10 to each other by passing through the through holes 32 of the connection plate 30. The through holes 32 of the connection plates 30 of the two heat insulating blocks to be joined together are overlapped, and the connecting block 40 is passed through the formed double holes to connect the heat insulating block 10.

  The block main body 20 is configured such that the block main bodies 20 mesh with each other in order to prevent a gap from being formed between the blocks when the heat insulating blocks 10 are joined together. For this reason, as shown in FIG. 4, the block body 20 is provided with a meshing portion 60 projecting from the connection surface 50 on one side of the connection rod 50 with the coupling rod penetrating semicircular groove 52 as the center. ing. By press-bonding to the connection surface 50 of the heat insulating block 10 to which the meshing portion 60 is connected, the heat insulating materials are brought into close contact with each other to form a stable building foundation.

  Further, the meshing portion 60 includes a press-fit portion 62 having an angle of inclination on the surface of the meshing portion. The press-fit portion 62 is an inclined body that is provided on the surface of the meshing portion 60 and forms an acute angle toward the outside of the block body 20. Thereby, it press-bonds so that it may bite into the connection surface 50 of the other heat insulation block 10 to which the press-fit part 62 couple | bonds, and it became possible to comprise the heat insulation basic | foundation structure which raised the coupling force more.

  Further, as shown in FIGS. 1 and 7, the engaging portion 60 is provided with a convex fitting convex portion 70. The fitting convex portion 70 is a member in which a convex shape is further formed on the meshing portion 60 projecting from the joint surface 50. In addition, the fitting convex portion 70 is provided, and the connecting surface 50 is provided with a fitting concave portion 72. Since the fitting recess 72 is fitted to the fitting protrusion 70 of the adjacent heat insulating block 10, the fitting recess 72 has a female concave shape corresponding to the male shape of the fitting convex portion 70. It is recessed in the part which 70 contacts. When the heat insulating blocks 10 are coupled to each other, the fitting convex portion 70 is fitted into the fitting concave portion 72 of another heat insulating block 10 adjacent to the fitting convex portion 70. Thereby, the up-and-down shift | offset | difference at the time of coupling | bonding of the heat insulation blocks 10 can be prevented, and it became possible to form the foundation of a more accurate and stable building.

  When the through hole 32 of the connection plate 30 is connected and connected to another adjacent heat insulation block 10, the connection plates of the heat insulation blocks 10 to be connected to each other are connected so that the connection rod 40 penetrates and the heat insulation blocks 10 are connected to each other. It is formed at a position where it overlaps to form one through hole. Further, the central axis of the through-hole 32 is installed at a position moved inward of the block body 20 within a range in which the block body 20 can be elastically deformed.

  The through holes 32 of the heat insulating blocks 10 installed adjacent to each other are overlapped to form a double through hole 32. Since the through-holes 32 are overlapped, the tip of the connecting rod 40 can be inserted into the center of the through-hole 32. However, if the connecting rod 40 is further penetrated, it moves from the tip to a thicker portion, so that the overlapping joint pieces are You will be close to each other. As a result, the end of the through hole 32 is displaced from the end of the engagement portion 60 toward the inside of the block body 20, and as shown in FIG. 5, the connecting rod 40 penetrates the through hole 32 when the heat insulating blocks 10 are joined together. Due to the mutual pressing force, the heat insulating blocks 10 are pressed against each other as shown in FIG. 6 by biting into the connection surface 50 of the other heat insulating block 10 to which the press-fit portion 62 is coupled. Thereby, it becomes possible to comprise the heat insulation foundation which raised the adhesion degree of the heat insulation blocks 10 more.

  As shown in FIG. 3A, the connecting rod 40 is a rod-shaped member having a circular cross section, and includes a heat insulating block fixing portion 42 and a through hole insertion end 44. The heat insulation block fixing portion 42 is a cylindrical rod body having a diameter of the same size as the through hole 32 of the connection plate 30. Further, the through hole insertion end 44 is a wedge-shaped portion formed so that the diameter becomes narrower from the heat insulation block fixing portion 42 toward the tip of the connecting rod 40. As shown in FIG. 3B, the heat insulating block fixing portion 42 is provided with a helical thread groove 46 for screwing into the through hole 32 and screwing the connection plates 30 together.

  Since the central axis of the through hole 32 of the connection plate 30 is installed at a position moved in the block body 20 inside, the holes are displaced when the through holes of the two heat insulating blocks 10 to be connected are overlapped. The position and the hole are not a perfect circle but a lens-like shape. When the through hole insertion end 44 is inserted into the substantially lens-shaped hole while applying pressure, the central axes of the overlapped through holes 32 approach each other, and when the connecting rod 40 is inserted to the heat insulating block fixing portion 42, The central axes of the through holes 32 coincide with each other. Under the present circumstances, it press-fits to the connection surface 50 of the other heat insulation block 10 which the meshing part 60 protruded from the connection surface 50 of the heat insulation block 10 connects, and the press-fit part 62 of the meshing part 60 connects the connection surface of the other heat insulation block 10 to couple | bond. Will cut into 50. Thereby, the coupling | bonding force and contact | adhesion power of heat insulation blocks 10 improved markedly, and it became possible to form the foundation of the stable building. Since the helical thread groove 46 is cut in the heat insulating block fixing portion 42, when the connecting rod 40 is inserted into the through hole 32 as shown in FIGS. The length of the connecting rod 40 screwed into 32 can be finely adjusted. Thereby, it becomes possible to hold and install the heat insulation block 10 at a uniform height at a fixed position regardless of the shape and height of the bottom surface on which the heat insulation block 10 is installed.

  As shown in FIGS. 7 and 8, the fitting convex portion 70 of the meshing portion 60 protrudes from the meshing portion 60 while narrowing the vertical and horizontal widths, and is formed in a truncated pyramid having a protruding end portion as an upper surface. The fitting recess 72 is formed in a shape corresponding to the fitting protrusion 70. By adopting this shape, when the meshing portion 60 is pressure-bonded to the joint surface 50, the fitting convex portion 70 is inserted while expanding the fitting concave portion 72. Therefore, the fitting convex portion 70 and the fitting concave portion 72 are used. In addition to preventing displacement when the heat insulating blocks are joined together, it is possible to construct a heat insulating foundation that further enhances the bonding force and adhesion between the heat insulating blocks.

  As an example of the press-fit portion 62 provided in the meshing portion 60, as shown in FIGS. 1 and 4, it is possible to make the convex shape further rise from the surface of the meshing portion 60 protruding from the joint surface 50. Further, the inclination angle of the press-fit portion 62 can be formed in a shape having an inclination of about 7 degrees toward the outside with the connecting rod penetrating semicircular groove 52 as the center. By setting it as such a shape, the crimping | compression-bonding efficiency by the penetration of the press-fit part 62 with respect to the connection surface 50 of the other heat insulation block 10 improves, and it becomes possible to comprise the heat insulation foundation which raised the bond strength and the adhesive force more. It was.

Moreover, as shown in FIG. 12, the adjacent heat insulation block 10 which makes a pair with this is provided with a concave fitting concave portion 92 in the meshing slope portion 80. When the respective through holes 32 of the connection plate 30 of the heat insulating block 10 which is a pair are overlapped, the holes are shifted from each other, and a shape like a hole lens is formed. When the through hole insertion end 44 is inserted into the substantially lens-shaped hole while applying pressure, the central axes of the overlapped through holes 32 approach each other, and when the connecting rod 40 is inserted to the heat insulating block fixing portion 42, The central axes of the through holes 32 coincide with each other. Thereby, a pair of heat insulation block 10 is crimped | bonded.

  The fitting convex portion 90 is a member that is fitted into a fitting concave portion 92 described later provided in the heat insulating block 10 that forms a pair. By fitting the fitting convex part 90 into the fitting concave part 92, it becomes possible to prevent the vertical shift at the time of joining of the heat insulating blocks 10. In addition, although the fitting convex part 90 is provided in the joining base part 88a of the meshing slope part 80 in a present Example, you may provide in the joining edge part 88b.
