  However, the conventional construction method shown in FIG. 6 has a problem that the working efficiency is low since two or more workers are required.

  On the other hand, in the case of the base bracket 20 shown in FIG. 7, since the alignment between the base D and the anchor bolt B is unnecessary, the work efficiency is improved, but a plurality of bases are formed between the base 30 and the base D. In a building in which the receiving brackets 20, 20,... Are interposed, the load applied to each of the base receiving brackets 20, 20,. When a large external force such as an earthquake is applied to such a building, an excessive force is concentrated on any of the base receiving brackets 20, 20, ..., and the base receiving brackets 20, 20, ... are deformed. There was a fear. When the base brackets 20, 20, ... are deformed, the parallel of the bases D is broken, and obstacles such as inclination of the building and cracks in the wall occur.

  The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a base support capable of efficiently performing work even when the base is placed directly on a base, and the base support. Provide use.

  (1) A base support according to the present invention is a base support which is removably attached to a base of a building and temporarily supports the base when the base is fixed to the top end of the base, A plate-like support portion for supporting a base, an engagement portion suspended to one end of the support portion and engaged with one side surface of the base, and a position suspended from the other end side of the support portion An abutment portion disposed at a distance from the engagement portion and brought into contact with the other side surface of the foundation, and a cane bridged between the abutment portion and the other end of the support portion And the length dimension of the support portion is larger than the thickness dimension of the base, and the base is configured to be fitted between the engagement portion and the contact portion. I assume.

  The base support of the present invention is removably attached to the base of a building, and temporarily supports the base when the base is fixed to the top end of the base. The base support includes a flat plate-like support portion for supporting the base, and an engagement portion suspended from one end of the support portion and engaged with one side surface of the base. There is. In addition, a contact portion to be in contact with the other side surface of the foundation is disposed at a position suspended from the other end side of the support portion and at a distance from the engagement portion, and this contact portion The bearing portion and the carrier portion are connected by a horizontal cane portion that is bridged between the other end of the carrier portion and the contact portion. Further, the length dimension of the above-mentioned support portion is larger than the thickness dimension of the foundation on which the foundation support is mounted, and the foundation is fitted between the engaging portion and the abutment portion.

  In such a base support, the foundation is inserted between the engaging portion and the abutting portion, and the engaging portion is engaged with one side surface of the foundation, and the abutting portion is the other Abut on the side. Also, the top end of the base is brought into contact with a part of the support portion of the base support. This allows the base support to be easily attached to the base and to be easily removed from the base.

  At this time, as described above, since the length dimension of the support portion is larger than the thickness dimension of the base on which the base support is mounted, a part of the support portion protrudes outward from the top end of the base. Two such base supports are mounted at a distance from each other in the longitudinal direction of the base, and the bases are mounted on the supports of both base supports so as to bridge the base between the two base supports. At this time, the base is placed such that a predetermined region including the center line thereof is positioned at a portion projecting outward from the top end of the base of the two support portions, thereby opening the through hole for the anchor bolt. The foundation does not get in the way when doing.

  By the way, the work of attaching both foundation supports to the foundation and the work of placing the foundation on both foundation supports can be carried out by a single worker, and by both foundation supports attached to the foundation. Since the foundation is supported, the opening work of the aforementioned through hole can also be carried out by one worker. When the opening operation is completed, the base is removed from both base supports, and both base supports are removed from the base, and then the anchor bolt provided on the base is inserted into the through hole of the base to Place on top. Therefore, even when the foundation is placed directly on the foundation, the work can be performed efficiently.

  (2) The base support according to the present invention is characterized in that the support portion, the engagement portion, the contact portion and the cane portion are integrally formed of a band plate material.

  In the base support according to the present invention, for example, the band plate material is bent to integrally form the support portion, the engagement portion, the contact portion, and the cane portion. This makes it possible to obtain a foundation support with high structural strength, but at the same time make the manufacturing cost as inexpensive as possible.

  (3) The base support according to the present invention is characterized in that an angle formed between the engagement portion and the support portion is an acute angle.

  In the base support according to the present invention, the angle formed between the engagement portion and the support portion is an acute angle, preferably about 75 ° or more and about 85 ° or less. By this, the engaging portion can be firmly engaged without being pulled out of the base.

  (4) The base support according to the present invention is characterized in that an angle formed by the support portion and the cane portion is about 40 ° to about 50 °.

  In the base support according to the present invention, the angle formed by the support portion and the cane portion is about 40 ° or more and about 50 ° or less. When the angle formed by the support portion and the cane portion is less than about 40 ° and more than about 50 °, the support force of the support portion by the cane portion is low in any case and can not withstand the load from the base carried on the support portion. There is a risk.

  (5) In the use of the base support according to the present invention, at least two base supports according to any of the above (1) to (4) are arranged at a distance from each other in the longitudinal direction of the foundation of the building. The foundation is inserted between the engagement portion and the abutment portion of both foundation supports, and the engagement portion is engaged with one side surface of the foundation while the abutment portion is on the other side surface of the foundation The base supports are detachably attached to the base by bringing the base supports into contact with each other by bringing a part of the supports of the base supports into contact with the top end of the base. The base is placed on the

  In the use of the base support according to the present invention, at least two base supports according to any one of the above (1) to (4) are disposed at a distance from each other in the longitudinal direction of the foundation of the building, The foundation is inserted between the engagement portion and the abutment portion of both foundation supports, and the engagement portion is engaged with one side of the foundation while the abutment portion is placed against the other side of the foundation. Both base supports are releasably attachable to the base by bringing them in contact with each other and bringing part of the supports of both base supports into contact with the top end of the base, and on the supports of both base supports. Since the base is placed, as in the case before, even when the base is placed directly on the base, work can be performed efficiently.

  (6) The use of the base support according to the present invention is a support of both base supports, one side of the base being supported by a portion located on the base, and the support of both base supports It is characterized in that the other side of the base is carried by the part extended from the base.

  In the use of the base support according to the present invention, the support part of both base supports is supported by one side of the base on the part located on the base, and the support part of both base supports is The other side of the base is carried by the part extended from the base. By this, one side of the base is supported by the base, 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 base via the cane portion and the contact portion of the base support is also reduced, and wrinkles and the like are generated on the other side of the base Is prevented.

It is a front view of a base support concerning the present invention. It is a side view of a base support concerning the present invention. It is a top view of a base support concerning the present invention. It is a perspective view which shows the use condition of the base support shown in FIGS. It is a perspective view which shows the use condition of the base support shown in FIGS. It is an explanatory view 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 receiving bracket disclosed by patent document 1. FIG.

The base support according to the present invention will be described in detail based on the drawings.
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 alterations 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 figures, parts corresponding to each other are denoted by the same reference numerals.

  As shown in FIGS. 1 to 3, the base support 1 is formed by bending one end portion of a band plate material formed by appropriately forming a material having strength, such as metal or synthetic resin, as described later. An engaging portion 11 for engagement is formed, and a portion connected to the engaging portion 11 is a carrier 10 for supporting a base. That is, the engaging portion 11 is suspended at one end of the carrier 10.

  Here, the length dimension of the engaging portion 11 is about 20 mm or more and about 50 mm or less. If the length dimension of the engagement portion 11 is less than about 20 mm, a required engagement force can not be obtained with respect to the foundation, and the foundation support 1 may be detached from the foundation during work. On the other hand, when the length dimension of the engagement portion 11 exceeds about 50 mm, the structural strength of the engagement portion 11 is reduced, and there is a possibility that the operation of engaging the strength foundation support 1 with the foundation may be hindered. On the other hand, when the length dimension of the engagement portion 11 is about 20 mm or more and about 50 mm or less, the base support 1 is prevented from being detached from the base during work since it has a sufficient engagement force with the base. At the same time, the operation of engaging the base support 1 with the base can be carried out smoothly.

  Further, the angle α between the engaging portion 11 and the carrying portion 10 is an acute angle, whereby the tip end of the engaging portion 11 is firmly engaged with one side surface of the base, and the engaging portion 11 is from the base Extraction is prevented. Specifically, the angle α is about 75 ° or more and about 85 ° or less. If the angle α is less than about 75 ° or if the angle α exceeds about 85 °, the engagement force of the tip of the engagement portion 11 to the base side is reduced, so the engagement portion 11 is removed from the base There is a risk of getting out.

  The soft member may be detachably attached to the distal end portion of the engaging portion 11. By this, generation | occurrence | production of the wrinkles etc. to the one side 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 supporting portion 10 described above is appropriately set to about 300 mm in accordance with the width dimension of the base to be supported thereon, whereby the supporting portion 10 stably supports the entire base. It is possible to

  Note that a plurality of grooves are formed in the surface of the support portion 10 on which the base is supported, or an elastic member such as a rubber material is attached to the surface of the support portion 10 on which the base is supported. It may be configured to be able to prevent the base from shifting in the plane of the support portion 10. In the case of the latter, since the surface of the support portion 10 supporting the base has elasticity, it is possible to absorb an impact applied to the base supported thereon, which is preferable.

  In addition, the width dimension of the band plate material mentioned above is about 40 mm or more and about 100 mm or less. Thereby, the required structural strength of the base support 1 can be secured, and carrying of the base support 1, installation on the base, storage, etc. can be smoothly performed. On the other hand, when the width dimension of the band plate is less than about 40 mm, the required structural strength can not be obtained, and when the width dimension of the band plate exceeds about 100 mm, the mass and bulk of the base support 1 Is an excessive factor, which hinders the carrying of the base support 1, installation and storage on the base, and the like.

  The portion extending from the carrier 10 to the opposite side to the engaging portion 11 is bent to the same side as the engaging portion 11 to form a lateral cane 12 for supporting the carrier 10 The portion extending from the portion 12 to the opposite side to the support portion 10 is a contact portion 14 which is bent in a posture substantially orthogonal to the support portion 10 and abuts on the other side surface of the base .

  Here, the angle β between the cane portion 12 and the support portion 10 is about 40 ° to about 50 °, and it is between the support portion 10 and the other side surface of the foundation against which the contact portion 14 abuts Act as a diagonal material. When the angle β is less than about 40 ° and more than about 50 °, the supporting force of the support portion 10 by the cane portion 12 is low in any case, and there is a possibility that the load from the base can not be received.

  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 base is sufficiently dispersed, In addition, it is possible to smoothly carry the base support 1, install it on the base, store it, and the like. On the other hand, when the length dimension of the contact portion 14 is less than about 100 mm, the load applied to the base from the contact portion 14 is concentrated, and the other side surface of the base against which the contact portion 14 abuts 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 can be carried, installed on a base, stored, etc. Interfere with

  By the way, between the contact part 14 and the engaging part 11 mentioned above is made a size slightly larger than the thickness size of the foundation according to the thickness size of the foundation, thereby inserting the foundation between the two. It is supposed to Thus, the dimension between the contact portion 14 and the engagement portion 11 may be slightly larger than the thickness dimension of the foundation, but, for example, the contact portion 14 and the tip of the engagement portion 11 It is preferable that the dimension between them is 120 and several mm. Since the width dimension of the foundation is set to 120 mm in many cases on the basis of a house in Japan, if the dimension between the contact portion 14 and the tip of the engagement portion 11 is 120 mm or less, When the base is inserted between the contact portion 14 and the engagement portion 11, rattle is not easily generated in the base support 1, and the work of opening the through hole in the base as described later is smoothly performed. Can.

  In addition, since the width dimension of the foundation has several values, a plurality of types of foundation supporting members 1, 1 having dimensions set between the contact portion 14 and the tip of the engagement portion 11 are set according to the dimension values thereof. It may be prepared in advance.

  On the other hand, the elastic member or the soft member may be detachably attached to the surface of the contact portion 14 that is to be in contact with the side surface of the base. By this, generation | occurrence | production of the wrinkles etc. to the other side 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 condition of the base support 1 shown in FIGS. 1 to 3, FIG. 4 shows the state before supporting the base and FIG. 5 shows the state after supporting the base Shows the state of. In addition, the same number is attached to the part corresponding to each part shown to FIGS. 1-3 in both figures, The description is abbreviate | omitted.

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

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

  As described above, the length dimension of the support portion 10 of the base support 1 is longer than twice the width dimension of the foundation 30, and accordingly, as shown in FIG. The other side is projected outward from the other side of the foundation 30. The projecting portion of the support portion 10 is supported by a contact portion 14 abutting on the other side surface of the cane portion 12 and the base 30, and the support portion 10 is parallel to the top end 31 of the base 30 in its entire area. It is held in posture.

  After the two base supports 1, 1 are thus attached to the base 30, as shown in FIG. 5, the laid base D 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 an area on the base 30 of both the carriers 10 and 10, and the other side of the base D is located in an area projecting from the base 30 for both the carriers 10 and 10. However, as shown in FIG. 5, an appropriate area including the center line of the base D is located in the area protruding from the base 30 of the both carriers 10, 10. This prevents the blade of the electric drill from coming into contact with the foundation 30 when the through holes for inserting the anchor bolts B, B,. .

  The positions from the center line of the foundation 30 of the anchor bolts B, B,... Provided on the foundation 30 are determined in advance based on, for example, measurement values using relief ink attached to the top end 31 of the foundation 30, The center line of the base D attached to the base D and the positions of the anchor bolts B, B, ... from the center line of the base 30 and the base D supported by the base supports 1 and 1 face the base D From the positions of the anchor bolts B, B, ..., the positions of the through holes to be opened in the base D are respectively determined, and the through holes are 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 the respective through holes are opened in the base D, after removing the base D from the both base supports 1, 1, the both base supports 1, 1 are removed from the base 30. Since the base support 1 is attached to the base 30 by inserting the base 30 between the contact portion 14 and the engagement portion 11 of the base support 1 as described above, the base support 1, 1 is used as a base 30 can be easily removed. Thus, after removing the base supports 1, 1 from the base 30, the base D is positioned on the top end 31 of the base 30, and the respective anchor bolts B, B, Are inserted and washers (not shown) are externally fitted to the portions of the anchor bolts B, B,... Projecting from the base D, and the base D is fixed to the base 30 by bolt tightening.

  In such a base support 1, the above-described base D is positioned on the top end 31 of the base 30, and the respective anchor bolts B, B,. Other than each operation, that is, mounting work of the base support 1, 1 on the base 30, mounting work of the base D on the base support 1, 1 mounted on the base 30, each through hole to the base D The opening operation of and the operation of fixing the base D by washers and bolts can be performed by one worker. Therefore, the work efficiency is high.

  Further, by fitting 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 formed as a foundation. Since the base support 1 can be attached to the base 30 by bringing the base support 30 into contact with the other side of the base 30, the mounting operation of the base support 1 to the base 30 can be easily performed. It is also easy to remove the base 30 from the base 30.

  Furthermore, when the base support 1 is attached to the base 30, the support portion 10 of the base support 1 is in contact with the top end 31 of the base 30, so as described above, one side of the base D is When arranged so as to be located in the region on the base 30 of both the support portions 10, 10, one side of the base D is supported by the base 30, and the load applied from the base D to the base support 1 is reduced. Ru. As a result, the deterioration of the base support 1 is alleviated, while the load applied to the other side of the base 30 via the lateral cane 12 and the abutment 14 of the base support 1 is also reduced. It is prevented that wrinkles etc. occur on the other side.

  In the present embodiment, the base support 1 is described in which the support portion 10, the engagement portion 11, the side cane portion 12, and the contact portion 14 are integrally formed using a band plate material, but the present invention is not limited thereto. Not limited to the above, parts corresponding to the support portion 10, the engagement portion 11, the lateral wand portion 12 and the contact portion 14 may be prepared and fixed by welding or the like. In that case, the width dimensions of the carrier portion 10, the engagement portion 11, the square bar portion 12 and the contact portion 14 can be made different from one another. For example, the width dimension of the engaging portion 11 and the contact portion 14 is made larger than the width dimension of the carrier portion 10. By this, while the engagement force to foundation 30 of engaging part 11 is raised more, the load applied to foundation 30 from contact part 14 can be distributed further.
