The other side of the foundation is supported on the portion extending from the foundation. Thus, one side of the base is supported by the foundation, and the load applied from the base to the base support is reduced. Therefore, while the deterioration of the base support is reduced, the load applied to the other side of the foundation via the cane part and the contact part of the base support is also reduced, and wrinkles and the like are generated on the other side of the base. It is prevented.

It is a front view of the base support tool which concerns on this invention. It is a side view of the base support tool which concerns on this invention. It is a top view of the base support tool which concerns on this invention. It is a perspective view which shows the use condition of the base support tool shown in FIGS. It is a perspective view which shows the use condition of the base support tool shown in FIGS. It is explanatory drawing explaining the conventional construction method which fixes a foundation to a foundation. It is a longitudinal cross-sectional view which shows the usage condition of the base metal fitting disclosed by patent document 1. FIG.

A base support according to the present invention will be described in detail with reference to the drawings.
Note that the base support described in the present embodiment is an example for explaining the gist of the present invention, and it goes without saying that the present invention includes modifications and modifications without departing from the gist.

  1 to 3 are a front view, a side view, and a plan view of a base support according to the present invention. In these drawings, parts corresponding to each other are denoted by the same reference numerals.

  As shown in FIGS. 1 to 3, the base support 1 is based on a base material as described later by bending one end portion of a band plate material formed of a material having appropriate strength such as metal or synthetic resin. An engaging portion 11 for engaging is formed, and a portion connected to the engaging portion 11 is a carrying portion 10 that carries a base. That is, the engaging portion 11 is suspended from one end portion of the carrying portion 10.

  Here, the length dimension of the engaging part 11 is about 20 mm or more and about 50 mm or less. When the length dimension of the engaging part 11 is less than about 20 mm, a required engaging force cannot be obtained with respect to a foundation, and there exists a possibility that the base support tool 1 may remove | deviate from a foundation during an operation | work. On the other hand, when the length dimension of the engaging part 11 exceeds about 50 mm, the structural strength of the engaging part 11 is lowered, and there is a risk of hindering the work of engaging the strength base support 1 with the foundation. On the other hand, when the length dimension of the engaging part 11 is about 20 mm or more and about 50 mm or less, since it has sufficient engaging force with respect to a foundation, it prevents that the base support tool 1 remove | deviates from a foundation during work. In addition, the work of engaging the base support 1 with the foundation can be performed smoothly.

  Further, the angle α formed by the engaging portion 11 and the carrying portion 10 is an acute angle, whereby the tip of the engaging portion 11 is firmly engaged with one side surface of the foundation, and the engaging portion 11 is removed from the foundation. Pulling out is prevented. Specifically, the angle α is about 75 ° or more and about 85 ° or less. When the angle α is less than about 75 °, or the angle α exceeds about 85 °, the engaging force to the base side surface of the tip of the engaging portion 11 is reduced. There is a risk of getting out.

  In addition, you may make it the structure which attaches a soft member to the front-end | tip part of the engaging part 11 so that attachment or detachment is possible. Thereby, generation | occurrence | production of the wrinkles etc. to the one side surface of the foundation by the front-end | tip part of the engaging part 11 can be avoided.

  On the other hand, the length of the carrying part 10 described above is an appropriate dimension of about 300 mm according to the width dimension of the foundation to be carried thereon, so that the carrying part 10 can stably carry the entire foundation. Can be done.

  A plurality of grooves are formed on the surface of the supporting unit 10 that supports the base, or an elastic member such as a rubber material is attached to the surface of the supporting unit 10 that supports the base, and the base is placed on the supporting unit 10. The base may be configured to prevent the base from being displaced in the plane of the supporting unit 10. In the latter case, since the surface of the carrier 10 that supports the base has elasticity, it is possible to absorb an impact applied to the base supported thereon, which is preferable.

  In addition, the width | variety dimension of the strip | belt board material mentioned above is made into about 40 mm or more and about 100 mm or less. As a result, the required structural strength of the base support 1 can be ensured, and the base support 1 can be carried, installed on the foundation and stored smoothly. On the other hand, if the width dimension of the strip material is less than about 40 mm, the required structural strength cannot be obtained, and if the width dimension of the strip material exceeds about 100 mm, the mass and bulk of the base support 1 Is excessively large, which hinders the carrying, mounting and storage of the base support 1 on the foundation.

  A portion extending from the carrying portion 10 to the side opposite to the engaging portion 11 is bent to the same side as the engaging portion 11 to form a cane portion 12 that supports the carrying portion 10. A portion extending from the portion 12 to the opposite side of the carrying portion 10 is bent into a posture substantially orthogonal to the carrying portion 10 and is made into a contact portion 14 that comes into contact with the other side surface of the foundation. .

  Here, the angle β formed by the cane portion 12 and the carrying portion 10 is about 40 ° or more and about 50 ° or less, and between the other side surface of the foundation on which the abutting portion 14 abuts and the carrying portion 10. It acts as a diagonal material. When the angle β is less than about 40 ° and exceeds about 50 °, the support force of the carrier portion 10 by the cane portion 12 is low, and there is a possibility that the load from the base cannot be endured.

  On the other hand, the length dimension of the contact portion 14 is about 100 mm or more and about 250 mm or less, whereby the load applied from the contact portion 14 to the foundation is sufficiently dispersed so Can be avoided, and the base support 1 can be carried around, installed on the foundation and stored smoothly. On the other hand, when the length dimension of the contact part 14 is less than about 100 mm, the load applied to the foundation from the contact part 14 is concentrated, and the other side surface of the foundation contacted by the contact part 14 is wrinkled. In addition, when the length dimension of the contact portion 14 exceeds about 250 mm, the mass and bulk of the base support 1 become excessive, and the base support 1 is carried, installed on the foundation, and stored. Cause trouble.

  By the way, the space between the contact portion 14 and the engagement portion 11 described above is set to a size that is slightly larger than the thickness of the foundation, that is, the foundation is inserted between the two. It is supposed to let you. Thus, although the dimension between the contact part 14 and the engagement part 11 should just be a little larger than the thickness dimension of a foundation, for example, the contact part 14 and the front-end | tip of the engagement part 11 are sufficient. It is preferable that the dimension between them is 120 several mm. In many cases, the width of the foundation is set to 120 mm in the foundations of homes in Japan. Therefore, when the dimension between the contact portion 14 and the tip of the engaging portion 11 is 120 several mm, When the foundation is inserted between the contact portion 14 and the engaging portion 11, the base support 1 is less likely to be rattled, and the work of opening a through hole in the base as described later is smoothly performed. Can do.

  In addition, since there are several values for the width dimension of the foundation, a plurality of types of base support tools 1 in which the dimension between the abutting portion 14 and the tip of the engaging portion 11 is set according to these dimension values. 1, ... may be prepared in advance.

  On the other hand, you may make it the structure which attaches an elastic member or a soft member to the surface made to contact | abut to the side surface of the foundation of the contact part 14 so that attachment or detachment is possible. Thereby, generation | occurrence | production of the wrinkles etc. to the other side surface of the foundation by the contact part 14 can be avoided.

  Using such a base support 1, a through hole is opened in the base as follows.

  4 and 5 are perspective views showing the use state of the base support 1 shown in FIGS. 1 to 3, FIG. 4 shows a state before the base is supported, and FIG. 5 shows a state after the base is supported. Each state is shown. In both figures, parts corresponding to those shown in FIGS. 1 to 3 are denoted by the same reference numerals, and description thereof is omitted.

  A foundation 30 having a height of about several tens of centimeters and a thickness of about several tens of centimeters is extended along the outline of the building. A plurality of anchor bolts B, B,... Are erected at an appropriate distance from each other on the top end (upper surface) 31 of the foundation 30 and passing through a substantially central position in the thickness direction. .

  As shown in FIG. 4, at least two base supports 1, 1 are detachably attached to the foundation 30 at an appropriate distance from each other in the longitudinal direction of the foundation 30. Specifically, by inserting the foundation 30 between the contact portion 14 and the engagement portion 11 described above of the base support 1, the engagement portion 11 is engaged with one side surface of the foundation 30, and The contact portion 14 is brought into contact with the other side surface of the foundation 30, and the carrying portion 10 of the base support 1 is brought into contact with the top end 31 of the foundation 30. The base supports 1 and 1 are attached in the longitudinal direction of the foundation 30 at positions where the anchor bolts B, B,... Are not provided.

  As described above, the length of the carrier 10 of the base support 1 is longer than the width of the base 30 by two or more times. Therefore, as shown in FIG. The opposite side protrudes outward from the other side surface of the foundation 30. The protruding portion of the carrying portion 10 is supported by the abutment portion 14 that abuts on the cane portion 12 and the other side surface of the foundation 30, and the carrying portion 10 is parallel to the top end 31 of the foundation 30 in all areas. Held in posture.

  After the both base supports 1, 1 are thus attached to the foundation 30, as shown in FIG. 5, the base D, which has been laid down, is placed on the support portions 10, 10 of the base supports 1, 1. . At this time, one side of the base D is located in a region on the foundation 30 of the two supporting portions 10 and 10, and the other side of the base D is located in a region protruding from the base 30 of the both supporting portions 10 and 10. However, as shown in FIG. 5, an appropriate region including the center line of the base D is located in a region protruding from the foundation 30 of both the supporting portions 10 and 10. This prevents the blade of the electric drill from coming into contact with the foundation 30 when a through hole for inserting the anchor bolts B, B,... Is inserted at a required position of the base D using an electric drill or the like. .

  The position of the anchor bolts B, B,... Provided on the foundation 30 from the center line of the foundation 30 is obtained in advance based on, for example, a measured value using a relief mark attached to the top end 31 of the foundation 30. The center D of the base D attached to the base D and the positions of the anchor bolts B, B,... From the center line of the foundation 30, and the base D supported by the base supports 1, 1 and the base D The position of each through hole to be opened in the base D is determined from the position of each anchor bolt B, B,..., And a through hole is opened in the base D at each determined position. The diameter of each through hole is slightly larger than the diameter of the anchor bolts B, B,.

  When each through hole is opened in the base D, the base D is removed from the base supports 1, 1 and then the base supports 1, 1 are removed from the foundation 30. As described above, since the foundation support 1 is attached to the foundation 30 by inserting the foundation 30 between the contact portion 14 and the engaging portion 11 of the foundation support 1, the foundation supports 1, 1 are used as the foundation. 30 can be easily removed. Thus, after removing the base supports 1 and 1 from the foundation 30, the foundation D is positioned on the top end 31 of the foundation 30, and each anchor bolt B, B, .. Are inserted, a washer (not shown) is externally fitted to the portion of the anchor bolts B, B,... Protruding from the base D, and the base D is fixed to the foundation 30 by tightening the bolts.

  In such a base support 1, the above-mentioned base D is positioned on the top end 31 of the foundation 30, and each anchor bolt B, B,... Of the foundation 30 is inserted into each through hole of the base D. Each work other than the above, that is, the mounting work of the base supports 1, 1 to the base 30, the placement work of the base D on the base supports 1, 1 attached to the base 30, each through-hole to the base D The opening work and the work of fixing the base D with washers and bolts can be carried out by one worker. Therefore, working efficiency is high.

  Further, by inserting the foundation 30 between the contact portion 14 and the engagement portion 11 of the base support D, the engagement portion 11 is engaged with one side surface of the foundation 30 and the contact portion 14 is used as the foundation. Since the base support 1 can be attached to the foundation 30 by abutting against the other side surface of the base 30, the base support 1 can be easily attached to the base 30. The operation of removing the base 30 from the foundation 30 can also be easily performed.

  Further, when the base support 1 is attached to the foundation 30, the carrier 10 of the base support 1 is configured to contact the top end 31 of the base 30, so that one side of the base D is as described above. If it arrange | positions so that it may be located in the area | region on the base 30 of both the support parts 10 and 10, the one side side of the base D will be supported by the base 30, and the load applied to the base support 1 from the base D will be reduced. The As a result, the deterioration of the base support 1 is reduced, while the load applied to the other side surface of the base 30 via the wand portion 12 and the contact portion 14 of the base support 1 is also reduced. It is possible to prevent wrinkles from occurring on the other side surface.

  In the present embodiment, the base support 1 is described in which the carrier portion 10, the engaging portion 11, the cane portion 12, and the abutting portion 14 are integrally formed using a band plate material. However, the present invention is not limited to this, and parts corresponding to the carrying part 10, the engaging part 11, the cane part 12 and the abutting part 14 may be prepared and fixed by welding or the like. In that case, the width dimensions of the carrying part 10, the engaging part 11, the cane part 12 and the contact part 14 can be made different from each other. For example, the width dimension of the engaging part 11 and the contact part 14 is made larger than the width dimension of the carrier part 10. As a result, the engaging force of the engaging portion 11 to the foundation 30 can be further improved, while the load applied to the foundation 30 from the contact portion 14 can be further dispersed.
