Description

  The present invention relates to a temporary material ruler used when positioning and arranging a temporary material for a residential foundation in a mold before placing ready-mixed concrete.

  To form housing foundations such as cloth foundations and solid foundations with concrete, for example, "anchor bolts" for fixing the foundation are suspended from the formwork, or vents or traffic openings (multiple under the floor) For example, a "raw stop" for forming a hole through which a person can pass through the foundation of the base is fixed to the formwork. These anchor bolts and raw concrete stoppers are collectively referred to as temporary materials.

  The anchor bolt that is a temporary material is arranged at a position different from the housing basic reinforcing bar and cannot be directly attached to the housing basic reinforcing bar. In this case, a jig called a temporary material ruler (defined as a metal form ruler in Patent Document 1) is used. It is used and positioned in the formwork before placing the ready-mixed concrete.

  In the technique of Patent Document 1, as described in the summary, “a temporary installation for a partition foundation that can be accurately positioned while preventing the displacement and the lateral flow of the upper end position of the anchor bolt during construction of the partition foundation. For the purpose of “providing a method for positioning the material”, as shown in FIG. 10, “below the metal foam ruler 7 that is horizontally attached to the upper end of the metal foam 2 when the partition foundation using the metal foam 2 is constructed. A method of positioning an anchor bolt for partitioning foundation in which the anchor bolt 9 is positioned so that the upper end of the anchor bolt 9 is positioned. The upper end of the anchor bolt 9 is added via a connection nut 12a and connected to the lower end of the bolt 12. Then, the upper end of the extension bolt 12 is positioned above the metal foam ruler 7 and its height is set. Configuration that adjusted so as to be connected to the metal form ruler 7 while "has been adopted.

Japanese Patent Laid-Open No. 11-6159, abstract, representative diagram

  According to the “positioning method of the anchor bolts for the partition foundation” of this Patent Document 1, it is considered that the above object can be achieved, but how to position the “metal foam ruler 7” itself with respect to the formwork. In the end, positioning of the “anchor bolt 9” seems to be difficult.

  The anchor bolt, which is a temporary material, can not be fixed accurately unless it is in the correct position for subsequent fixing of the base. In particular, in recent residential construction, so-called “precutting” is performed at a factory called “precutting”, and at the construction site, the work of “assembling” various materials such as foundations and pillars that have been precut. It has become. For this reason, if the anchor bolt is not arranged at the designed position of the residential foundation, even if the precut base is fixed, the position of the base does not become the position as designed.

  Moreover, the intervals at which the anchor bolts are arranged also differ depending on the house maker, and the metal foam ruler described in Patent Document 1 must have a specification for each house maker. In both manufacturing and storage, the cost increases. The above can also be said to “temporary concrete stop” which is a temporary material.

  In particular, the metal foam ruler of Patent Document 1 requires a hole for attaching the metal foam ruler to the upper flange of the mold as shown in FIG. It is not applicable. Of course, the interval between the holes formed in the metal foam must be matched to the interval between the holes of the metal foam ruler used for this. Therefore, if it is going to employ | adopt the metal-form ruler of this patent document 1, it will be inevitably cost-related.

  Therefore, the present inventors, when supporting the temporary material, can easily determine the position thereof, is easy to construct, can be provided at a low cost, and does not increase the construction cost. As a result of various studies on how to use the ruler, the present invention has been completed.

  That is, the object of the present invention is to firstly allow the temporary material support to the formwork via the temporary material support plate to be easily performed at a specified position, and secondly, The object is to provide a temporary material ruler that can easily determine the support position of the temporary material that meets the specifications of each house maker, is easy to construct, and can be realized at low cost.

In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the best mode described below.
“Temporary material ruler 10 for positioning a temporary material support plate 30 for supporting a temporary material 40 that is placed on a formwork 20 for forming a residential foundation and embedded in the residential foundation. And
A plurality of mounting projections 12 for mounting the temporary material support plate 30 are formed on the side end surface 11a of the base 11 constituting the temporary material ruler 10 so as to protrude from the flange 21 of the mold frame 20. Characteristic temporary ruler 10 ”
It is.

  As shown in FIG. 5 or FIG. 7, the temporary material ruler 10 according to claim 1 includes an attachment projection 12 for attaching the temporary material support plate 30 to the side end surface 11 a of the base 11 constituting the temporary material ruler 10. A plurality of protrusions are formed so as to protrude from the side end face of the mold 20. As shown in FIG. 1 or FIG. 5, these mounting projections 12 may be installed in a state of projecting to the outside of both mold frames 20, but inside of both mold frames 20, that is, ready-mixed concrete is cast. In some cases, it is used so as to protrude toward the other side.

  Each temporary material ruler 10 includes a base 11 having a certain length, a plurality of mounting protrusions 12 protruding therefrom, and mounting holes 12 a formed in the mounting protrusions 12. The mounting protrusion 12 to be used is used when connecting a plurality of temporary material rulers 10 or when connecting to a T-type ruler 51 or an L-type ruler 52 described later. In general, a residential foundation is formed in a layout as illustrated in FIG. 1, but often intersects with a “T-shape” or “L-shape” rather than with a cross. A T-shaped ruler 51 and an L-shaped ruler 52 that determine the “origin” of the mounting position of the temporary material 40 are installed at the intersections of these “T-shaped” and “L-shaped”. The temporary material ruler 10 according to the present invention is attached to the mold ruler 51 and the L-shaped ruler 52.

  The T-type ruler 51 and the L-type ruler 52 are provided with attachment holes 53 as shown in FIGS. 4A to 4E. The attachment holes 53 of the T-type ruler 51 and the L-type ruler 52 are provided. As shown in FIGS. 4B to 4E, the T-shaped ruler 51 and the L-shaped ruler 52 may be formed on a portion protruding from the base portion, but FIG. As shown, it may be formed inside the base portion.

  Of course, these mounting holes 53 correspond to the mounting holes 12a formed in the mounting projections 12 of the temporary material ruler 10 according to the present invention. The mounting holes 12a and the mounting holes 53 include bolts, By inserting the pins at the same time, the two are connected. When this pin or bolt is inserted, each mounting projection 12 and mounting hole 53 are formed so as to protrude from the base 11, that is, so as to avoid the flange 21 of the mold 20, so that the bolt The tip of the pin does not come into contact with the mold 20, and when the mounting protrusion 12 and the mounting hole 53 are aligned with each other, the “stone” is simply and reliably inserted.

  If the temporary material ruler 10 according to the present invention is attached to the T-type ruler 51 or the L-type ruler 52 as described above, the temporary material ruler 10 is placed on the flange 21 of the mold 20. As shown in FIG. 5, each mounting projection 12 projects from the flange 21 of the mold 20. Needless to say, a predetermined number of temporary material rulers 10 are connected according to the dimension between the T-shaped ruler 51 or the L-shaped ruler 52 as described above.

  Then, by placing each temporary material ruler 10 on the flange 21 of the mold frame 20, each mounting protrusion 12 protruding from the base portion 11 also protrudes from the flange 21 of the mold frame 20. Even if the projection of each mounting projection 12 from the flange 21 of the mold 20 is on the outside as shown in FIG. 2 or on the opposite side (inside the mold 20) from FIG. The case is also very noticeable. Since each attachment protrusion 12 attaches the temporary material support plate 30, the attachment position of these temporary material support plates 30 is also conspicuous. As a result, the temporary material support plate 30 can be easily attached. It is.

  Furthermore, since each temporary material support plate 30 has an attachment hole 31 for attaching and suspending a temporary material 40 such as an anchor bolt or a live concrete stopper, the temporary material 40 can be attached using this attachment hole 31. Since the position of the temporary material support plate 30 itself is determined by the temporary material ruler 10 according to the present invention, the mounting position of each temporary material support plate 30 is defined. Become.

  Therefore, the temporary material ruler 10 according to claim 1 is configured to easily support the temporary material 40 with respect to the mold 20 via the temporary material support plate 30 at a specified position. Construction is simple and can be realized at low cost.

In order to solve the above-mentioned problem, the means taken by the invention according to claim 2 is the temporary material ruler 10 according to claim 1,
“Each mounting protrusion 12 is formed at intervals of multiples of the least common multiple of the dimensions between the temporary members 40 expressed as integers in centimeters.”
It is.

  For example, when an anchor bolt is used as the temporary material 40, it is a specification that a certain house maker fixes the base at intervals of 50 centimeters, while other house maker has a base at intervals of 40 centimeters. Is a specification for fixing “50”, the least common multiple of “40” is “10”.

  Therefore, in the temporary material ruler 10 according to claim 2, the interval between the mounting protrusions 12 is set to 10 centimeters, which is the least common multiple of “10”, or 20 centimeters or 30 centimeters of the multiple. I did it. If the mounting protrusions 12 are formed so as to protrude at such intervals, the temporary material ruler 10 can suspend the temporary material 40 in accordance with the construction specifications of at least two companies.

  Therefore, the temporary material ruler 10 according to the second aspect exhibits the same function as that of the first aspect, and can easily determine the support position of the temporary material 40 according to the specifications of each housing manufacturer. It has become.

Moreover, in order to solve the said subject, the means which the invention which concerns on Claim 3 took is about the temporary material ruler 10 in any one of the said Claim 1 or Claim 2,
“A pair of temporary material rulers 10 are connected by a connecting plate 13 so that the inner width of the pair of temporary material rulers 10 is equal to the thickness of the housing foundation.”
It is.

  That is, the temporary material ruler 10 according to claim 3 is formed by connecting a pair of the temporary material ruler 10 by the connecting plate 13 as shown in FIG. 8, and in this case, the inner width of the pair of temporary material ruler 10 is the housing. The thickness of the foundation is used. As a result, as shown in FIG. 2, a large number of mounting projections 12 can be arranged just by placing each temporary material ruler 10 on the assembled formwork 20. The arrangement of the mounting projections 12 for positioning the plate 30 can be performed easily and reliably.

  Accordingly, the temporary material ruler 10 according to the third aspect exhibits the same function as that of the first or second aspect, and can be installed on the mold 20 within a short time.

Furthermore, in order to solve the said subject, the means which the invention which concerns on Claim 4 took is about the temporary material ruler 10 in any one of the said Claims 1-3,
“Each mounting protrusion 12 protrudes to the outside of each mold 20”
It is.

  In the temporary material ruler 10 according to this fourth aspect, each mounting projection 12 protrudes to the outside of each formwork 20 (to be outside the housing foundation) as shown in FIG. 2 or FIG. It is what. Thus, if each attachment protrusion 12 protrudes outside the flange 21, it will also protrude outside from the flange 21 of the formwork 20, and the position of each attachment protrusion 12 will become very conspicuous. is there. For this reason, the attachment position of the temporary material support plate 30 with respect to the temporary material ruler 10 is also sufficiently clear.

  Therefore, the temporary material ruler 10 according to the fourth aspect of the present invention exhibits the same function as that of the first to third aspects, and more prominently positions the mounting protrusions 12 to which the temporary material support plate 30 should be attached. Thus, the temporary material support plate 30 and the temporary material 40 can be attached more easily.

And in order to solve the said subject, the means which the invention which concerns on Claim 5 took is about the temporary material ruler 10 in any one of the said Claims 1-4,
“The curved surface portion 12b is formed on the outer end surface of each mounting projection 12”
It is.

  That is, in the temporary material ruler 10 according to claim 5, as shown in FIG. 9, a curved surface portion 12 b is formed on the outer end surface of each mounting projection 12, and the temporary material 40 is formed by the curved surface portion 12 b. This prevents the attachment protrusions 12 from being caught (when the attachment protrusions 12 protrude inward) and the worker's clothes from being caught (when the attachment protrusions 12 protrude outward).

  Accordingly, the temporary material ruler 10 according to the fifth aspect of the present invention exhibits the same function as that of the first to fourth aspects, and can prevent the mounting protrusions 12 from interfering with the work. is there.

As described above, in the present invention,

FIG. It is a partial exploded perspective view which shows the technique shown by patent document 1. FIG.

  The invention according to each claim configured as described above will be described according to the temporary material ruler 10 which is the embodiment shown in the drawings, but before that, the formwork 20 to which the temporary material ruler 10 should be adopted or The situation of the temporary material support plate 30 will be described including the relationship with the foundation for housing formed by these.

  Each mold 20 is formed from a steel plate or the like as a material. For example, as shown in FIG. A flange 21 protruding outside the foundation is formed. The flange 21 serving as the side edge of the plate base is used for connecting a plurality of the molds 20, and the flange 21 serving as the lower edge is used for fixing and positioning the mold 20 with respect to the ground. The flange 21 formed on the upper edge of the mold 20 forms the placement surface of the temporary material ruler 10, and in this embodiment, the flange 21 on the upper edge is No mounting holes for the temporary material ruler 10 are formed.

  The foundation for housing is formed in a layout as illustrated in FIG. 1, but often intersects with a “T-shape” or “L-shape” rather than with a cross. Moreover, the foundation for housing is formed by hardening the placed ready-mixed concrete, and this ready-mixed cast-in space is formed by a number of layouts as illustrated in FIG. This is a formwork 20. Then, a T-type ruler 51 and an L-type ruler 52 that determine the “origin” of the attachment position of the temporary material 40 are installed at the intersections described above, and with respect to these T-type ruler 51 and L-type ruler 52. The temporary material ruler 10 according to the present invention is attached.

  In order for the temporary material ruler 10 to be mounted while being positioned on the T-type ruler 51 or the L-type ruler 52, the T-type ruler 51 or the L-type ruler 52 must have a portion for positioning the temporary material ruler 10. Although it is not, it is the mounting hole 53 shown to (a)-(e) of FIG. 4A to 4E show various types of T-type ruler 51 or L-type ruler 52. The T-type ruler 51 and the L-type ruler 52 are shown in FIG. A mounting hole 53 is formed on the flange 21 of the mold 20 on the outer side of the placement portion so that the mounting protrusions 12 of the temporary material ruler 10 according to the present invention overlap each other.

  The mounting holes 53 of the T-type ruler 51 and the L-type ruler 52 are portions protruding outward from the base portion of the T-type ruler 51 and L-type ruler 52, as shown in FIGS. However, as shown in FIG. 4A, it may be formed inward from the base portion.

  As shown in FIG. 2 and FIG. 3, various forms of the temporary material support plate 30 are adopted. Basically, each attachment of the temporary material ruler 10 according to the present invention, which will be described later, is used. The left and right attachment holes 31 for attaching to the protrusions 12 and the central support hole 32 for attaching the temporary material 40 are provided.

  Now, as shown in FIG. 5 or FIG. 7, the temporary material ruler 10 according to the present invention has an attachment projection 12 for attaching the temporary material support plate 30 to the side end surface 11 a of the base 11 constituting the temporary material ruler 10. A plurality of protrusions are formed so as to protrude from the side end face of the mold 20.

  FIG. 5 shows a temporary material ruler 10 according to the first embodiment of the present invention. The temporary material ruler 10 according to the first embodiment is similar to the second embodiment shown in FIGS. It is not a “ladder-like” one like the temporary material ruler 10 but a “single” one as shown in FIG. Therefore, the temporary material ruler 10 according to the first embodiment is installed for each formwork 20 installed in parallel with the width of the housing foundation, and is a “ladder-like” temporary material ruler 10. Compared to, manufacturing and storage are much easier. Needless to say, the temporary material ruler 10 according to the first embodiment is not limited by the width of the housing foundation because it is only necessary to individually place the flanges 21 on the flanges 21 facing each other.

  The temporary material ruler 10 shown in FIG. 5A has a base 11 that has the same width as the flange 21 of the mold 20, and the base 11 is placed on the flange 21. Each base 11 protrudes outward (in the state shown in FIG. 5) or inward from the flange 21. The temporary material ruler 10 shown in FIG. 5B is obtained by making the base 11 longer than that shown in FIG. 5A and has the mounting protrusion 12 described above.

  Further, as shown in FIG. 5, this “one-piece” temporary material ruler 10 has attachment holes at both ends for connecting it to the T-type ruler 51 and the L-type ruler 52 described above. In addition, the positioning projection 14 and the positioning hole 14a formed in the positioning projection 14 are also provided. The positioning projection 14 is formed on the side of the base 11 opposite to the mounting projection 12 described above, but if the mounting projection 12 can be used when connecting to the T-type ruler 51 or the L-type ruler 52. Is not always necessary.

  The temporary material ruler 10 which is “one” is constructed as shown in FIG. 2, but in this construction example, a T-shaped ruler 51 is indicated by an imaginary line. In accordance with 53, holes and positioning protrusions 14 formed at the end of each temporary material ruler 10 side are used. Specifically, a hole formed in the end on the temporary material ruler 10 side or a positioning hole 14a of the positioning projection 14 is aligned with an attachment hole 53 of the T-shaped ruler 51, and a pin, bolt, or screw is inserted into both holes. Thus, the temporary material ruler 10 and the T-shaped ruler 51 are connected.

  In order to position the temporary material ruler 10 with respect to the flange 21 of the mold 20, a fixed frame 60 as shown in FIGS. 6A and 6B may be employed. As shown in FIG. 6B, the fixed frame 60 is fitted into both the mold frames 20 and the arm portion 61 to be locked to the outer end portion of the flange 21 of the mold frame 20. The fitting frame 62 is provided in a state in which the temporary material ruler 10 placed on the flange 21 is pressed against the flange 21 as shown in FIG. 6 (c). 60 is fitted to the flange 21. As a result, the flange 21 of each mold 20 is sandwiched between the arm portion 61 and the fitting portion 62, and the upper end of each mold 20 is fixed by the fixed frame 60. Each temporary material ruler 10 is fixed on the flange 21.

  FIGS. 7 and 8 show a temporary material ruler 10 according to the second embodiment of the present invention. This temporary material ruler 10 is different from the above-mentioned “one piece” ruler, and the temporary material ruler 10. A pair of 10 is connected by a connecting plate 13 to form a “ladder shape”, and a pair of inner widths of the temporary material ruler 10 is set to be a thickness of the housing foundation. As shown in FIG. 2, the ladder-like temporary material ruler 10, as shown in FIG. 2, with respect to a pair of molds 20 assembled to form a housing foundation, if the base 11 is placed on each flange 21, it is left as it is. It can be used. Of course, the temporary material ruler 10 also has the base 11 and the mounting projection 12 described above.

  In other words, the temporary material ruler 10 according to the second embodiment has less merit in manufacturing and storage than the above-described single temporary material ruler 10, but each of the pair of molds 20 facing each other. It has a construction merit that it only has to be placed on the flange 21. Further, the ladder-like temporary material ruler 10 is implemented from a short one as shown in FIG. 8 (a) to a long one as shown in FIG. 8 (b).

  Then, both the temporary material ruler 10 according to the second embodiment and the temporary material ruler 10 according to the first embodiment form the curved surface portions 12b on the outer end surfaces of the mounting projections 12, as shown in FIG. Therefore, the clothes of the worker are caught (when each attachment projection 12 protrudes inward) without being caught by temporary members 40 such as live concrete stoppers and anchor bolts inserted into both molds 20 (each attachment). (When the protrusion 12 protrudes inward).

  As the curved surface portion 12b, as shown in FIG. 9A, it is sufficient to form it at the tip of each mounting projection 12, but as shown in FIG. It becomes more effective if it is formed not only at the corner of the projection 12 but also at the boundary between the mounting projection 12 and the base 11.

  Each of the temporary material rulers 10 described above can be formed by punching using a press or the like from a single plate including the mounting projections 12, the connecting plates 13, or the positioning projections 14. It is simple and the cost can be kept low.
