Description

  The present invention relates to a screw for fixing a pier (body edge) to a pillar material or the like via a heat insulating material, and more particularly to a screw reinforcing member for reinforcing the screw.

  The construction method in which the heat insulating material is installed on the inner side of the structure, that is, on the indoor side has been adopted in many architectures until now, and this method gives a large temperature change to the structure body when the outside temperature rises and falls. For this reason, the indoor air temperature is easily affected as the temperature of the outside air rises and falls.

  On the other hand, an outer heat insulating structure has been developed in which a heat insulating material is installed outside the structure, that is, outside the room, and the entire building is wrapped with the heat insulating material. This can utilize the whole building as a heat storage. By adopting an external heat insulation structure, there are few effects on the enclosure due to changes in the outside air temperature, extending the life of the building, reducing the burden of cooling and heating, and other advantages such as suppressing condensation.

  FIG. 6 is a cross-sectional view showing a configuration example of a conventional outer heat insulating structure. In the figure, there is an outer wall 30 between the outside 10 of the building and the indoor side 20. The outer wall 30 includes, in order from the indoor side 20, a cross 31, a wall plate 32 made of plywood, a column member 33, a structural plywood 34, a heat insulating material 35, a crosspiece (body edge) 36, and an exterior plate 37. .

  In the above configuration, the crosspiece 36 is a square member thinner than the column member 33. The screw 40 is screwed from the outside of the crosspiece 36, passes through the crosspiece 36, the heat insulating material 35, and the structural plywood 34, and is screwed into the pillar member 33 to be fastened and fixed. The exterior plate 37 is attached and fixed to the crosspiece 36 with screws or metal fittings (not shown).

  As the heat insulating material 35, hard foamed polyurethane having a thickness of several centimeters, glass fiber, or the like is used, and these are all low in strength as a structural material. Therefore, the screw 40 is close to 0 in strength at the portion of the heat insulating material 35. On the other hand, since the crosspiece 36 supports the exterior plate 37, the force applied to the exterior plate 37 is applied to the screw 40, and the screw 40 is easily warped or bent.

  On the other hand, conventionally, it has been mainly handled by increasing the strength of the screw 40, but under such conditions of use, it is difficult to manufacture a screw having sufficient strength.

  The present invention has been conceived from such a situation, and an object of the present invention is to provide a screw reinforcing member capable of giving sufficient strength to a screw for fixing a pier to a pillar member or the like via a heat insulating material. .

  In order to achieve the above object, the screw reinforcing member of the present invention is used for a screw for fixing a pier to a pillar material or the like via a heat insulating material, and has a length substantially the same as the thickness of the heat insulating material. It has the columnar body which can penetrate.

  The columnar body is configured to be hollow, or the columnar body includes a hollow main body having one end opened and the other end bottomed, and a lid covering the opening of the main body, or the lid It can be set as the structure which a body screws together with the said main body with a screw.

  The above-described screw reinforcing member is used as follows.

  After the structural plywood is attached to the pillar material, a heat insulating material is attached thereon, and a hole is formed in which the columnar body enters at a position corresponding to the pillar material of the heat insulating material. A columnar body is put in this hole, a pier is piled up from above, and a screw is screwed from the outside of the pier. The screw penetrates the pier, further penetrates the columnar body and is screwed into the pillar material or the like, and fixes the pier to the pillar material or the like.

  According to the present invention, the bending stress applied to the portion passing through the heat insulating material of the screw can be received by the columnar body, and the strength of the columnar body can be sufficient. There is an excellent effect that it can be supported with sufficient strength.

  When the columnar body has a hollow structure, the heat insulation effect can be increased without substantially reducing the strength.

  By using the columnar body as a bottomed hollow cylindrical main body and a lid, the main body can be fixed with a small screw. By adopting a structure in which the main body and the lid are screwed together, the coupling between the main body and the lid can be simplified and the coupling force can be strengthened.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a cross-sectional view showing an outer heat insulating structure using the screw reinforcing member of the present invention, and corresponds to a cross-sectional view taken along the line II of FIG. The same components as those in the conventional example of FIG. 6 are denoted by the same reference numerals, and different configurations will be mainly described.

  A hole is formed in the heat insulating material 35, and a columnar body 45 as a screw reinforcing member is fitted therein. The columnar body 45 is fixed to the column member 33 with a plurality of small screws 47. The screw 40 for fixing the crosspiece 36 passes through the crosspiece 36, the columnar body 45, and the structural plywood 34 and is screwed and fixed to the pillar material 33.

  FIG. 2 is an exploded cross-sectional view of the columnar body 45. The columnar body 45 includes a hollow cylindrical bottomed main body 45a and a lid body 45b that closes the opening of the main body 45a. The main body 45a and the lid body 45b are both made of plastic and are coupled by fitting or an adhesive. By making the columnar body 45 as a screw reinforcing member have a hollow structure, it is possible to increase the heat insulation without substantially reducing the strength. Further, the material can be reduced, and the manufacturing cost of the screw reinforcing member can be reduced.

  Next, the usage method will be described.

  A structural plywood 34 is hit against the pillar member 33, and a heat insulating material 35 is stuck thereon. When using the columnar body 45 as a screw reinforcing member, a hole having the same diameter as that of the columnar body 45 is formed in advance at a position facing the column member 33 of the heat insulating material 35. Only the main body 45 a of the columnar body 45 is put into this hole, and is fixed to the column member 33 with a plurality of four to eight small screws 47. When the main body 45a is fixed, the lid body 45b is attached and fixed. The thickness of the columnar body 45 is set so that the outer surface of the lid 45b is the same as the outer surface of the heat insulating material 35. A pier 36 is assigned to the outside of the heat insulating material 35, and the pier 36 is fixed to the pillar member 33 with a screw 40. The screw 40 passes through the pier 36, the columnar body 45, and the structural plywood 34, and is screwed into the column member 33 to be fixed.

  Since the screw 40 penetrates the columnar body 45 instead of the heat insulating material 35, all the bending stress applied to the screw 40 is received by the columnar body 45. Since the columnar body 45 has a strength higher than that of the heat insulating material 35, by setting the outer diameter and thickness of the columnar body 45 appropriately, it is possible to support the pier 36 and the exterior plate 37 without increasing the strength of the screw 40. The required strength can be obtained. The screw 40 is fixed by being screwed to the pillar member 33. However, if the structural plywood 34 has a sufficient thickness, the screw 40 need not be screwed to the pillar member 33.

  The screw 40 desirably penetrates the center of the columnar body 45, but is not limited thereto. As long as the bending stress applied to the screw 40 is within the limit that can be received by the columnar body 45, the screw 40 may pass through a position off the center of the columnar body 45.

  FIG. 3 is a cross-sectional view showing an outer heat insulating structure using the second embodiment of the screw reinforcing member of the present invention. The columnar body 55 as the screw reinforcing member has a structure shown in FIG.

  In other words, the main body 55a has a solid cylindrical shape made of plastic, and a large number of small holes are formed therethrough. The lid 55b uses heat-insulating rubber or the like. The screw 40 passes through the rubber lid 55b, passes through one of the small holes in the main body 55a, passes through the structural plywood 34, and is screwed into the column member 33 to be fixed. The main body 55a and the structural plywood 34 are fixed with an adhesive or the like, but may not be fixed. A rubber cap 41 is provided on the head of the screw 40 to increase the heat insulation effect.
