Description of the Related Art Conventionally, as a base for fixing a weight device such as a vending machine in a state where it is placed, one having vending machine leg mounting means on a concrete block surface is widely known. The vending machine leg mounting means includes a bolt used as a fixing means for fixing the vending machine, and has a structure for preventing the bolt from being removed with a narrow upper opening provided in the longitudinal direction of the rail embedded in the concrete. There are some which are fitted in a slidable state with the groove and fix the bolt according to the position of the leg of the vending machine. By using the base having such a structure, it is possible to cope with the case where the positions of the legs of the weight devices are different, and the weight devices can be easily installed.

  For example, in the vending machine basic block disclosed in Patent Document 1, bolts are used as means for fixing the block and the vending machine or the like. In Patent Document 1, a vending machine leg mounting means of a vending machine foundation block is a bolt groove formed on the upper surface of the foundation block, and the bolt groove is slidable by the bolt head so that the bolt head rotates. A head groove having a width that prevents the washer, a washer groove that is formed at an upper portion of the head groove and has a wider groove width than the head groove, and is capable of sliding a washer plate inserted into the bolt, and the washer groove The upper part is formed at the lower end with a narrower groove width than the head groove and washer groove, and the bolt shaft part is slidable, and the upper part is made up of a shaft part groove opened on the upper surface of the foundation block. There is disclosed a vending machine basic block in which a bolt used as a means for fixing is fitted in a slidable state.

  However, in the case where a bolt or the like fitted in a rail groove embedded in a base for mounting and fixing a weight device such as a vending machine is used as a fixing means with the weight device, the weight device In order to prevent the rails from falling down due to an earthquake or human external force, it is necessary to further improve the pull-out resistance of the rails with respect to the base on which the heavy equipment is installed. Further, in view of the large number of weight devices installed in and outside Japan, there is a market demand for a structure that can reduce the cost for manufacturing the foundation and facilitate the construction.

  For example, in the vending machine mounting basic block disclosed in Patent Document 1, a bolt groove for allowing the bolt to slide is formed in the block, and the shape of the washer groove provided in the bolt groove is formed. In addition, the presence of the reinforcing reinforcing bars embedded in the block improves the pull-out resistance of the bolt groove with respect to the block. However, the structure of the bolt groove and the presence of the reinforcing reinforcing bars are complicated, and the cost for manufacturing the block increases.

  Moreover, the structure mounting support platform disclosed in Patent Document 2 is a concrete support platform in which a plurality of stud bolts are fixed to a bottom surface of a rail groove used as a means for fixing the structure by welding. The anchor effect is being obtained for the buried rail. However, when the stud bolt is used as an anchor, it cannot be expected to obtain a sufficient anchor effect due to the shape of the bolt, and the rail and the rail come off from the concrete and work when the structure is about to fall down due to an earthquake or the like. It is not enough to withstand the pulling force.

  In addition, the device mounting base disclosed in Patent Document 3 provides an anchor effect by providing protruding edges on both sides of the bottom surface of the mold material in order to obtain a pull-out resistance of the mold material through which a device fixing bolt can be inserted into the mounting base. Trying to get. However, the mass increases due to the ratio of the protruding edge to the entire device mounting base, which is inconvenient in handling. Further, it is considered that the projecting portion is attached by welding in view of the shape of the mold material, and therefore, the cost for manufacturing the mold material is considered to increase.

  From the above, the present invention can improve the anti-pull-out performance for the foundation on which the weight device is installed and the manufacturing cost in the rail for embedding and fixing the weight device on the concrete base. An object of the present invention is to provide a rail that is low in height and easy to handle.

Rail main body used in rail with anchor arm: FIGS. 1 and 4 exemplarily show perspective views of rails I and II with anchor arm according to the present invention. As shown in FIG. The attached rails I and II have the same shape. In FIG. 7, sectional drawing in the surface perpendicular | vertical to the elongate direction of the rail main body with which the rail I with an anchor arm and the rail II with an anchor arm which concern on this invention are provided is shown. In FIG. 7, the rail body 10 is composed of a bottom surface portion 11, a first wall surface 12, and a second wall surface 13, and is composed of three wall surfaces, so that one surface side opens along the longitudinal direction. These are long members whose both ends are open ends and whose cross section in the width direction is substantially rectangular. In other words, the rail body 10 is in a state in which the first wall surface 12 and the second wall surface 13 face each other and are arranged in parallel with each other, and includes the opening 18 along the longitudinal direction of the rail body 2. .

  Here, the first wall surface 12 is completed and disposed substantially perpendicularly to the bottom surface portion from one side of the long bottom surface portion, and the first wall surface 12 has its opening side end facing the inside of the rail body. And a first anchor arm member connecting gap portion 16 is formed between the first folded wall surface 14 and the first wall surface 12. Similarly to the first wall surface 12, the second wall surface 13 is completed and arranged substantially perpendicularly to the bottom surface portion from the other side of the long bottom surface portion, and the opening side end portion faces the inside of the rail body.

In the arm-equipped rail II, the base end portion of the anchor arm 40 is provided for insertion. The rail body described above is used as a constituent member of the rail I with anchor arm and the rail II with anchor arm described below.

Form of Rail I with Anchor Arm: FIG. 8 is a cross-sectional view of the rail I with anchor arm, and corresponds to a cross-sectional view taken along line A-A ′ in FIG. 2. As can be understood from FIG. 8, the rail main body 10 is provided with a first anchor arm member connection gap portion 16 and a second anchor arm member connection gap portion 17 as a part of the shape thereof. The main spindle arm line portion 33 of each of the first anchor arm member 31 and the second anchor arm member 32 is connected and fixed to the first wall surface 12 and the second wall surface 13 of the rail body 10 by using bolts or the like. In the concrete base with rail manufactured using the rail with anchor arm having such a configuration, the resistance to pulling out of the rail portion embedded and arranged is dramatically improved as compared with the conventional product.

  The first anchor arm member 31 and the second anchor arm member 32 referred to here are spindle arms extending along the first wall surface 12 and the second wall surface 13 toward the lower portion of the rail body 10 (opposite the opening 18). The line portion 33 and the extended arm line portion 34 bent from the main shaft arm line portion 33 and extending toward the outside in the width direction of the rail body are continuous, and can be seen as a cross section of the rail I with anchor arm. In other words, it is substantially L-shaped.

  In addition, as a concept applicable to the rail I with an anchor arm according to the present invention, it is also preferable to connect the first wall surface 12 and the second wall surface 13 and the spindle arm line portion 33 by welding or the like. By performing such a connection process, the pull-out performance and stability of the rail with an anchor arm embedded in the concrete base with rail are further improved.

  It should be noted that the first anchor arm member 31 and the second anchor arm member 32 are processed into a substantially L-shaped shape referred to in the present invention, and have a material and shape having a predetermined strength. If it is provided, it can be used without being limited to the contents of the present application. For example, the thickness and width of the first anchor arm member 31 and the second anchor arm member 32 can be arbitrarily set. As can be understood from FIG. 8, the first anchor arm member connection gap portion 16 and the second anchor arm member connection gap portion 17 are provided as a part of the rail body 10, and are substantially L-shaped as a whole. The main shaft arm line portion 33 of each of the first anchor arm member 31 and the second anchor arm member 32 to be used is connected to the first connection through hole 19 and the second connection through hole 20 shown in FIG. Then, the rail body 10 is connected and fixed. At this time, by arranging the first anchor arm member and the second anchor arm member substantially symmetrically in the cross section in the width direction of the rail body, the stability of the pull-out resistance against the concrete bases embedded in the rail body is stabilized. Sex is planned.

  Further, the shaft portion, nut, and the like of the bolt 51 are arranged in a state of being inserted into the first anchor arm member connection gap portion 16 and the second anchor arm member connection gap portion 17. In this way, the shaft portion of the bolt is inside the first anchor arm member connection gap portion 16 and the second anchor arm member connection gap portion 17, so that interference with the heavy equipment fixing means bolt 52 can be prevented. Can be prevented.

  Note that welding or the like may be used as means for connecting and fixing the first anchor arm member 31 and the second anchor arm member 32 to the rail body 10. However, in this case, equipment for performing welding is newly required, and it is necessary to consider an increase in processing cost such as an increase in processing man-hours.

  The extension arm line portion of the first anchor arm member and the second anchor arm member has a width direction length L1 of the bottom surface portion of the rail body, and the extension arm line portion of the first anchor arm member and the second anchor L2 / L1 = 1.8 to 2.5 when the length between the proximal end of the arm member and the extension arm line part is L2, and the main spindle arm line part and the extension arm line part Is preferably 85 ° to 95 °. The ratio of the length between the proximal end of the extended arm line portion of the first anchor arm member and the extended arm line portion of the second anchor arm member to the length in the width direction of the bottom surface portion of the rail body, and the spindle arm By setting the angle between the line part and the extension arm line part in such a range, the anchor arm of the rail with the anchor arm exhibits a strong anchoring effect against the concrete base that is buried and is excellent. High pull-out resistance can be obtained.

  FIG. 8 is a cross-sectional view of the rail I with anchor arm according to the present invention cut along the line A-A ′ of FIG. 2. In FIG. 8, it has shown about the shape of the anchor arm 30 with which the rail I with an anchor arm which concerns on this invention is provided. Here, when the relationship of the length L2 between the distal end portions of the extension arm line portions 34 of the left and right anchor arms 30 to the width direction length L1 of the bottom surface portion of the rail body 10 is less than L2 / L1 = 1.8 In other words, the length of the bottom surface of the rail body 10 of the anchor arm 30 in the width direction becomes too short, and a sufficient anchor effect cannot be obtained. On the other hand, when the relationship exceeds L2 / L1 = 2.5, the length in the width direction of the bottom surface of the rail body 10 of the anchor arm 30 becomes too long, which is inconvenient in handling.

  Further, as shown in FIG. 8, when the angle between the spindle arm line portion 33 and the extension arm line portion 34 is in the range of 85 ° to 95 °, excellent pull-out resistance can be obtained. Here, when the angle formed between the spindle arm line portion 33 and the extension arm line portion 34 is less than 85 °, the angle in the extending direction of the extension arm line portion 34 and the drawing in the direction of the opening acting on the rail body 10 The force angle becomes too close to obtain a sufficient anchor effect. Furthermore, when the angle between the spindle arm line part 33 and the extension arm line part 34 exceeds 95 °, it cannot fulfill the role as a leg when installing the rail I with the anchor arm in the concrete mold. In order to lose stability during installation, a jig or the like is required. Furthermore, when the angle formed between the spindle arm line portion 33 and the extension arm line portion 34 is increased to about 180 °, the spindle arm line portion and the extension arm line portion are linear, and a sufficient anchor effect cannot be obtained.

  Then, although the form of the rail II with an anchor arm is demonstrated, the concept which can be used also as the form of the rail I with an anchor arm is described together in the following description.

Form of Rail II with Anchor Arm: FIG. 9 is a cross-sectional view of the rail II with anchor arm, and corresponds to a cross-sectional view taken along line B-B ′ in FIG. 5. As can be understood from FIG. 9, the rail body 10 is provided with a first anchor arm member connection gap portion 16 and a second anchor arm member connection gap portion 17 as a part of its shape, The base end portions of the first anchor arm member 41 and the second anchor arm member 42 are passed through the first connection through hole 19 and the second connection through hole 20 described above, and the first anchor arm member connection gap portion 16 and the first anchor arm member 41 are connected. The two anchor arm member connection gap portions 17 are inserted and arranged. The concrete base with rail manufactured using the rail with an anchor arm having such a configuration dramatically improves the pull-out resistance of the embedded rail portion compared to conventional products.

  Here, as can be understood from FIG. 9 and FIG. 10, the first anchor arm member 41 disposed through the first connection through hole 19 and the second connection through hole 20 of the rail body 10 shown in FIG. 7. And each of the 2nd anchor arm member 42 contacts the inner wall surface side contact part f and the outer wall surface side contact part g of the 1st wall surface 12 and the 2nd wall surface 13, and will be in the locked state. That is, with such a structure, the anchor arm 40 can be attached to the rail body only by a physical arrangement method without performing welding, brazing, or the like.

  In each of the first anchor arm member 41 and the second anchor arm member 42 used in the present invention, a rail connection arm line portion 43 extends from the base end side toward the outer side in the width direction of the rail body 10, and this rail connection is performed. An inclined arm line portion 44 that is bent from the arm line portion 43 and extends toward the anchor arm connection reference point 46 located at the lower center portion of the bottom surface portion, and is bent from the inclined arm line portion to the outside in the width direction of the rail body. And the extended arm line portion 45 extending toward the first anchor arm member connecting gap portion 16 of the rail body 10 includes a rail connecting arm of the first anchor arm member. The base end portion of the line portion is inserted and arranged, and the rail connection of the second anchor arm member is connected to the second anchor arm member connection gap portion 17. The first anchor arm member 41 and the second anchor arm member 42 are connected to the anchor arm connection reference point 46 and the width center point of the rail body in the cross section in the width direction of the rail body. Are arranged approximately symmetrically with a line connecting the two.

  As shown in FIG. 9, the first anchor arm member 41 and the second anchor arm member 42 according to the present invention are substantially Z-shaped, and include a rail connection arm line portion 43, an inclined arm line portion 44, and an extension arm line portion 45. And is composed of parts with different functions. The first anchor arm member 41 and the second anchor arm member 42 are connected and fixed at the anchor arm connection reference point 46, so that when the rail I with the anchor arm is installed in the concrete mold, the first anchor arm The effect which prevents that the member 41 and the 2nd anchor arm member 42 fall off from the rail main body 10 will be acquired. In addition, by performing connection and fixing at the anchor arm connection reference point 46, the concrete base with rail manufactured using the rail II with anchor arm has a resistance against pulling out of the rail portion embedded and disposed, compared with the conventional product. Compared to a dramatic improvement. Here, the connection and fixing method is not particularly limited, and may be a means that requires special equipment such as welding or may be secured by a string or the like, and the means is not selected.

  The first anchor arm member 41 and the second anchor arm member 42 according to the present invention are substantially Z-shaped members obtained by bending a rod-shaped metal wire, and the first anchor arm member 41 and It is preferable that the 1st connection through-hole 19 and the 2nd connection through-hole 20 of the rail main body 10 which insert the base end part with the 2nd anchor arm member 42 are cylindrical through-holes. Thus, by making the connection through holes 19 and 20 for connecting the anchor arm 40 to the rail body 10 cylindrical, drilling is facilitated, and the anchor arm is inserted into the connection through hole. It is possible to prevent the occurrence of backlash after the operation.

  Here, it is necessary to select the constituent material of the anchor arm member in consideration of the ease of bending as a metal material and the processing cost. As a result, the anchor arm members 41 and 42 are preferably rod-shaped metal wires. By using a rod-shaped metal wire as the anchor arm members 41 and 42, it is possible to bend the anchor arm members 41 and 42 at an arbitrary position relatively easily and at low cost. Here, for the first anchor arm member 41 and the second anchor arm member 42 constituting the rail II with anchor arm according to the present invention, a commercially available wire wire, stainless steel wire, wire wire, temper wire, piano It is possible to use a rod-shaped metal wire having a circular cross section, such as a wire, which can provide sufficient pull-out performance of the rail body against hardened concrete. Therefore, in the following description, a case where rod-shaped metal wires are used for the first anchor arm member 41 and the second anchor arm member 42 constituting the anchor arm 40 will be described as an example. The same applies to the drawings used in this description.

  It should be noted that the first anchor arm member 41 and the second anchor arm member 42 are processed into a substantially Z-shaped shape according to the present invention and have a material and shape having a predetermined strength. If equipped, it can be used without any limitation. For example, a wide metal member such as a substantially Z-shaped clamp may be used by bending a flat metal plate. However, since it is necessary to penetrate the base end side of the first anchor arm member 41 and the second anchor arm member 42 to the inside of the rail body, the ease and processing when the through hole is drilled in the rail body. Judgment must be made in consideration of costs.

  The proximal ends of the first anchor arm member 41 and the second anchor arm member 42 according to the present invention are inserted into the first connection through hole and the second connection through hole of the rail body, and the first anchor arm member connection gap is inserted. The proximal end of the first anchor arm member and the second anchor arm member located in the connecting portion and the second anchor arm member connection gap portion is at an angle of −90 ° to 30 ° with respect to the horizontal plane. Is preferred. FIG. 10 shows the disposition state of the distal end portion on the proximal end side of the first anchor arm member 41 or the second anchor arm member 42 located in the first anchor arm member connection gap portion 16 or the second anchor arm member connection gap portion 17. Indicates. As shown in FIG. 10, the anchor arm 40 positioned in the anchor arm connection gap portion has a base end side distal end portion of 0 ° to −90 ° on the c side with respect to the horizontal plane X or 0 ° to 30 on the b side. By setting the angle within the range of °, the anchor arm is not easily detached from the rail body even if the rail body 10 is pulled upward.

  Here, in the case where the proximal ends of the first anchor arm member 41 and the second anchor arm member 42 are less than −90 ° which is outside the range of the angle indicated by c with respect to the horizontal plane X, the rail body 10 It becomes difficult to insert the anchor arm 40 into the first connection through hole 19 and the second connection through hole 20 provided in the first wall surface 12 and the second wall surface 13. On the other hand, if the proximal ends of the first anchor arm member 41 and the second anchor arm member 42 exceed 30 °, which is outside the range of the angle indicated by b with respect to the horizontal plane X, an opening is formed in the rail body 10. When an upward pulling force is applied, the anchor arm 40 is easily removed from the rail body 10.

  When the diameters of the first anchor arm member and the second anchor arm member are R1, and the diameters of the first connection through hole 19 and the second connection through hole 20 of the rail body 10 are R2, R2 / R1 = 1.3-1.8 is preferable. FIG. 10 shows the relationship between the diameter R1 of the anchor arm 40 and the diameter R2 of the connection through holes 19 and 20. By setting the ratio of the diameter R2 of the connection through-hole to the diameter R1 of the anchor arm within this range, the anchor arm 40 can be easily dropped after the proximal end portion of the anchor arm 40 is inserted into the rail body 10. Will be prevented.

  Here, when R2 / R1 = less than 1.3, it becomes difficult to insert the anchor arm 40 into the through holes 19 and 20, and it becomes difficult to assemble the anchor arm 40 to the rail body 10. Further, when R2 / R1 = 1.8 is exceeded, the anchor arm 40 becomes loose after the anchor arm 40 is inserted into the through holes 19 and 20, and is easily dropped from the through holes 19 and 20.

  And the 1st anchor when the base end part of the 1st anchor arm member 41 concerning the present invention and the 2nd anchor arm member 42 is inserted in the 1st connection penetration hole 19 and the 2nd connection penetration hole 20 of rail body 10 The entry length into the arm member connection gap 16 and the second anchor arm member connection gap 17 is preferably 2 mm to 5 mm from the first wall surface 12 and the second wall surface 13. That is, by setting the lengths of the first anchor arm member and the second anchor arm member entering the first anchor arm member connection gap and the second anchor arm member connection gap to be in this range, It is possible to secure a sufficient amount of catching to prevent the base end portion from falling off the connection through hole of the rail body. From FIG. 10, when the approach length L4 is less than 2 mm, the catch amount of the base end portion of the anchor arm 40 with respect to the rail body 10 is reduced, and the anchor arm 40 is easily detached from the rail body 10. On the other hand, when the approach length L4 exceeds 5 mm, there is no change in the effect of preventing the anchor arm 40 from falling off the rail body 10, and the material cost for this length is wasted and not economical.

  And the 1st anchor arm member and the 2nd anchor arm member which are arranged in the 1st anchor arm member connection gap part and the 2nd anchor arm member connection gap part which are formed in the rail body of the rail with an anchor arm concerning this invention, An anchor arm drop prevention means may be provided at the proximal end side tip. In FIG. 11, the anchor arm dropout prevention means formed at the proximal end of the anchor arm 40 is disposed in the first anchor arm member connection gap 16 or the second anchor arm member connection gap 17. The state which further bent the front end side tip part of the 1st anchor arm member 41 or the 2nd anchor arm member 42 is shown. As shown in FIG. 11, in addition to bending the proximal end of the anchor arm 40, the anchor arm 40 can be made larger than the diameter of the connection through hole by welding or mechanical deformation. It is possible to more reliably prevent the rail body 10 from falling off.

  Here, as shown in FIG. 10, the proximal ends of the first anchor arm member 41 and the second anchor arm member 42 located in the first anchor arm member connection gap portion 16 and the second anchor arm member connection gap portion 17. After the side tip portion is bent at a predetermined angle with respect to the horizontal plane, the drop prevention effect can be further improved by employing a drop prevention means as shown in FIG.

  And as for the 1st anchor arm member and 2nd anchor arm member which concern on this invention, the rail connection arm line part is extended to the position of 5-20 mm of the width direction toward the outer side from the 1st wall surface and the 2nd wall surface. And it is preferable to be located below the surface of the opening side of the rail body. FIG. 10 shows a state where the rail connection arm line portion of the anchor arm member is inserted into a through hole provided in the rail body 10. From FIG. 10, the rail connection arm line portion of the anchor arm 40 has a length from the wall surface of the rail body 10 of L5 and is positioned below the surface of the rail body 10 on the opening side. I understand. Thus, the length L5 from the outside of the first wall surface and the second wall surface of the rail connection arm line portion of each of the first anchor arm member and the second anchor arm member extends within the above range, thereby improving the anchor effect. Improvement is achieved. Moreover, when the rail connection arm line portion is positioned below the surface of the rail body on the opening side, when the weight device is placed and fixed on the rail, it interferes with the leg of the weight device. Can be prevented.

  Here, when the length L5 from the outside of the first wall surface or the second wall surface of the rail connecting arm line portion is less than 5 mm, the inclination angle of the inclined arm line portion of the anchor arm is limited, and the rail main body of the anchor arm The length in the lower direction from the bottom is too long, which is inconvenient in handling. On the other hand, even when the length L5 from the outside of the first wall surface or the second wall surface of the rail connection arm line portion exceeds 20 mm, the length in the width direction of the bottom surface of the rail body of the anchor arm is too long. It becomes inconvenient in handling.

  The inclined arm line portions of the first anchor arm member and the second anchor arm member according to the present invention are rails when the height of the first wall surface and the second wall surface of the rail body is h1 from the bottom surface of the rail body. It is preferable that the bent portion (or anchor arm connection reference point) is located at a position of 0.8h1 to 3h1 from the bottom surface of the main body in the direction opposite to the opening. FIG. 8 shows the positional relationship between the height h1 of the rail body 10 and the bent portion of the anchor arm 30 in the rail I with anchor arm according to the present invention. FIG. 9 also shows an anchor arm connection reference point 46 for connecting and fixing the height h1 of the rail body 10 and the first anchor arm member 41 and the second anchor arm member 42 in the rail II with anchor arm according to the present invention. The positional relationship is shown. Here, when the position of the bent portion and the anchor arm connection reference point 46 is less than 0.8 h1 from the bottom surface of the rail body 10 toward the opposite direction of the opening with respect to the height h1 of the rail body 10. The length of the anchor arm in the lower direction of the rail body becomes too short, and a sufficient anchor effect cannot be obtained for the concrete base on which the anchor arm is embedded. On the other hand, when the position of the bent portion and the anchor arm connection reference point 46 exceeds 3h1 from the bottom surface of the rail body 10 in the direction opposite to the opening with respect to the height h1 of the rail body 10, The length downward from the bottom of the rail body becomes too long, which is inconvenient in handling.

  The extension arm line portion of the first anchor arm member and the second anchor arm member according to the present invention has a width direction length of the bottom surface portion of the rail body as L1, and the extension arm line portion of the first anchor arm member L3 / L1 = 1.8 to 2.5 when the length between the proximal end side distal end of the second anchor arm member and the extended arm line portion is L3, and the extended arm line portion and the horizontal plane It is preferable that the angle formed by -20 ° to 45 °. The ratio of the length between the distal end portions of the base end sides of the extension arm line portion of the first anchor arm member and the extension arm line portion of the second anchor arm member to the length in the width direction of the bottom surface portion of the rail body, and the extension By setting the range of the angle between the arm line part and the horizontal plane to such a range, the extended arm line part is for obtaining a sufficient pull-out resistance against the concrete base on which the rail body is embedded. A sufficient anchor effect will be exhibited.

  FIG. 12 is a cross-sectional view of the rail II with anchor arm according to the present invention cut along the line B-B ′ of FIG. 5. FIG. 12 shows the shapes of the first anchor arm member 41 and the second anchor arm member 42 included in the rail II with anchor arm according to the present invention. Here, the relationship of the length L3 between the proximal end ends of the extension arm line portions of the first anchor arm member 41 and the second anchor arm member 42 with respect to the width direction length L1 of the bottom surface portion of the rail body 10 is L3 /. When L1 = less than 1.8, the length in the width direction of the bottom surface of the rail body 10 of the anchor arm 40 becomes too short to obtain sufficient pulling resistance, and the relationship is L3 / L1 = When exceeding 2.5, the length of the anchor arm 40 in the width direction of the bottom surface of the rail body 10 becomes too long, which is inconvenient in handling.

  As shown in FIG. 12, when the inclination angle of the extension arm line portion 45 of the first anchor arm member 41 and the second anchor arm member 42 is X on the horizontal plane, the extension arm line portion 45 is placed on the horizontal plane X. On the other hand, the rail main body 10 can obtain sufficient pulling-proof performance by setting it within the range of 0 ° to −20 ° on the e side or 0 ° to 45 ° on the d side. Here, when the angle formed by the extension arm line portion 45 and the horizontal plane X is outside the range indicated by e and less than −20 °, the angle of the extension arm line portion 45 in the extending direction and the rail body 10 are affected. The angle of the pulling force toward the opening becomes too close, and the anchor arm cannot obtain a sufficient anchor effect. Further, when the angle formed by the extended arm line portion 45 and the horizontal plane X is less than −20 °, the function as a leg when the anchor arm rail II is installed in the concrete mold cannot be satisfactorily performed. In order to lose stability, a jig or the like is required. On the other hand, if the angle formed by the extended arm line portion 45 and the horizontal plane X exceeds 45 °, which is outside the range indicated by d, the angle formed by the extended arm line portion and the inclined arm line portion is too small, and the anchor The arm cannot obtain a sufficient anchor effect.

And it is preferable that the anchor arm with which the rails I and II with an anchor arm which concern on this invention are equipped is a member whose tensile load is 12.5 KN / mm < ² > or more. By using a member having a tensile load within this range in the anchor arm, the anchor arm can be prevented from breaking. If the anchor arm has a tensile load of less than 12.5 KN / mm ² , it is inserted into the rail body due to the pulling force acting in the direction of the rail opening against the rail body when the heavy equipment falls down. The anchor arm is deformed without being able to withstand.

  And the rail main body with which the rails I and II with an anchor arm which concern on this invention are equipped has the height of 20 mm-30 mm of the 1st wall surface and the 2nd wall surface, the length of the width direction of a bottom face part is 40 mm-50 mm, and thickness. Those of 1 mm to 3 mm are generally widely used. By making the dimensions and shape of the rail body within this condition range, it becomes a suitable size for installing heavy equipment that circulates in the market, and in the concrete when the concrete hardens when embedded in concrete It is strong enough to withstand the drying shrinkage that occurs with the evaporation of water.

  In addition, the rail body constituting the rails I and II with anchor arms according to the present invention is not particularly limited as long as it has a certain strength and does not deteriorate due to an elution component from the concrete. A base alloy material, an aluminum alloy hard material, or the like is preferable. Considering the balance between product cost and strength, as a material for the rail body, low carbon steel containing 1.2% or less of carbon, toughness obtained by adding a predetermined amount of chromium and nickel, and It is preferable to use stainless steel having excellent corrosion resistance. As described above, the material of the rail main body may be appropriately selected depending on the weight and usage of the installed weight devices.

  And the anchor arm with which the rails I and II with anchor arms according to the present invention are provided is a set of the first anchor arm member and the second anchor arm member, along the length in the longitudinal direction of the rail body, It is preferable to arrange a plurality of sets. Thus, by arranging a plurality of sets of the first anchor arm member and the second anchor arm member as one set, the direction of the pulling force acting on the rail body when the weight device falls down changes. In addition, sufficient pull-out resistance performance is exhibited at all portions of the rail body in the longitudinal direction. As shown in FIG. 1 to FIG. 3 and FIG. 4 to FIG. 6, the rail body 10 is hardened so that the rail body 10 is embedded and disposed by arranging the anchor arms 30 and 40 at least near the end side and the center of the rail body 10. Exhibits excellent pull-out resistance against concrete.

  And in the rail II with an anchor arm which concerns on this invention, in the state which inserted and arrange | positioned the base end part of a 1st anchor arm member and a 2nd anchor arm member in the 1st connection through-hole of a rail main body, and a 2nd connection through-hole. It is preferable that the first anchor arm member, the second anchor arm member, and the rail body are connected and processed at the positions of the first connection through hole and the second connection through hole. The connection processing here refers to, for example, welding or the like, and the first anchor arm member, the second anchor arm member, and the rail body are connected by welding or the like at the positions of the first connection through hole and the second connection through hole. Thus, there is no backlash between the anchor arm and the rail body, and the stability and improvement of the pull-out resistance of the rail body can be further improved.

  And in the rail II with an anchor arm according to the present invention, when the inclined arm line portions of the first anchor arm member and the second anchor arm member are arranged so as to contact the corners of the bottom surface portion of the rail body, The inclined arm line portion of the first anchor arm member and the second anchor arm member and the rail body may be connected at the contacted portion. The connection processing here refers to, for example, welding or the like, and by connecting the inclined arm line portions of the first anchor arm member and the second anchor arm member and the corner portions of the bottom surface portion of the rail body by welding or the like. It is preferable because the arrangement angle of the anchor arm with respect to the rail body is stable and the resistance to pulling out of the rail body can be improved.

  The concrete base stand in which the rails I and II with anchor arms according to the present invention are embedded can appropriately select a material used for producing concrete. In general, concrete is strong against compressive force but weak against tensile force. For example, ordinary concrete, which is a general concrete, can withstand a weight of about 100 kg in a 1 cm square, but has a resistance to a tension of only about 1/10 of about 10 kg. Because of the nature of this concrete, reinforced concrete with reinforcing bars in the concrete is sometimes used instead of using the concrete alone to compensate for the weak tensile force. In addition, in order to withstand the pulling force generated when the weight devices collapse, a water-cement ratio is reduced, or a mixture of fibers or the like in concrete is used. However, when these reinforced concrete and fiber reinforced concrete are used, the manufacturing cost increases. However, if the rail with an anchor arm according to the present invention is adopted, even if an inexpensive ordinary concrete base is used, the rail body exhibits excellent pulling resistance against the concrete base. Can do.

  By using the rail with an anchor arm of the present invention, it is excellent in pull-out performance against a concrete base, and is easy to handle when embedded in a concrete base. It becomes possible to provide a rail used for a concrete base with a rail.
