DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a horizontal structural member, a tension material, and a compression material according to the present invention are shown in FIGS. The horizontal structural member and the tension member of the present invention are structural members suitable for increasing the span of the frame structure in order to cope with the high functionality and diversity expected of the structure. By applying members and tensile materials to the frame structure of the structure, the proof strength and stickiness that can ensure safety against extremely rare earthquake loads required for the structure, as well as habitability and functionality Therefore, it is possible to realize a configuration that can be accommodated within a range of deformation that does not impair.
Moreover, the compression material of this invention is a structural member suitable for using for the vertical member of a foundation, an underground frame, etc. which need to support a great vertical load with the enlargement of the structure of a reinforced concrete structure.
These horizontal structural members, tensile materials and compression materials are all configured to use processed or used railroad rails as they are, so that the structural performance required for each structural member can be imparted at low cost. It is what makes it possible.
[0014]
As shown in FIG. 1 (a), a reinforced concrete frame structure 1 is composed of adjacent columns 2 and beams 3 that are horizontally arranged so as to bridge them. The column 2 is a reinforced concrete vertical structural member including a plurality of main reinforcing bars 2a and strips 2b and concrete 7, and the beam 3 includes upper reinforcing bars 4 made of reinforcing bars, as shown in FIG. It is a horizontal structural member made of reinforced concrete including a lower end reinforcement 5 and a loose reinforcement 6 and a concrete 7 in which these are embedded.
[0015]
The top bars 4 are reinforcing bars located in the vicinity of the top surface of the beam 3, and a plurality of the top bars 4 are arranged in parallel at a predetermined spacing so that a plurality of bars form a horizontal plane in the beam width direction. The plurality of lower end bars 5 are reinforcing bars located near the lower end surface of the beam 3, and are parallel to the upper end bars 4 and have a uniform spacing in the vertical downward direction with respect to each of the plurality of upper end bars 4. It is arrange | positioned in the height position which has. The plurality of upper reinforcing bars 4 and the lower reinforcing bars 5 are included in a plurality of ribs 6 arranged orthogonally to form a so-called car reinforcing bar 8, and the car reinforcing bar 8 is embedded in the concrete 7. The beam 3 is configured.
[0016]
By the way, in the present embodiment, as shown in FIG. 1 (a), the lower stripe 5 of the beam 3 located near the side surface has a portion of the beam 3 located near the center in the longitudinal direction having a predetermined length. The rail 9a is disposed in parallel with the uncut portion 5a forming the pair of the lower end bars 5 in a portion located in the vicinity of the central portion in the longitudinal direction.
The rail 9a has been used, and both ends thereof are formed with overlapping joints with the uncut portion 5a forming a pair of the lower end bars 5, A plurality of stud bolts 16 are fixed to the outer peripheral surface of the portion where the lap joint is formed through fixing means.
Therefore, the stress transmission between the rail 9a and the uncut portion 5a forming the pair of the lower end bars 5 is caused by the stud bolt being embedded in the concrete joint 7 as shown in FIG. 16 will be performed.
[0017]
As can be seen from FIG. 1A, the beam 3 having such a configuration is such that the rail 9 a is disposed in a part of the beam 3 in the vicinity of the central portion in the longitudinal direction. The rail 9a has a larger cross-sectional shape and higher rigidity than a rebar generally used as the lower end bar 5 of the beam 3. That is, the rail 9a functions as a reinforcing material that reinforces the longitudinal central portion of the lower end surface where a tensile stress is likely to occur when a vertical load is applied to the beam 3. The cracks of the concrete 7 can be suppressed.
[0018]
In the present embodiment, as shown in FIG. 1B, the arrangement position of the rail 9a is arranged only at the lower end 5 of the beam 3 located in the vicinity of the side surface. However, the arrangement position is not necessarily limited to this, and for example, the rails 9a may be used for the lower end bars 5 located in the intermediate portion of the beam 3 in the beam width direction.
[0019]
The rail rail 9a is arranged not only near the lower surface of the beam 3, but also on the rail located near the side surface of the upper end 4 of the beam 3, as shown in FIG. It is good also as a structure which arrange | positions the rail 9a.
The arrangement configuration is the same as that in the case where the beam is arranged at the lower end bar 5. As shown in FIGS. 2 (a) and 2 (b), the upper bar 4 of the beam 3 is located near the side surface of the beam 3. A portion located in the vicinity of the central portion in the longitudinal direction is cut out by a predetermined length, and a railroad rail 9a is disposed in a portion located in the vicinity of the central portion in the longitudinal direction. A lap joint is formed with the uncut portion 4a.
Thereby, since the railway rail 9a having high rigidity is located not only in the vicinity of the lower surface of the beam 3 but also in the vicinity of the upper surface of the beam 3, the beam 3 is configured to have a long span. In addition, since it is possible to stiffen the vicinity of the upper end surface where compressive stress is likely to occur when a vertical load is applied, the deflection of the beam 3 can be suppressed.
[0020]
As described above, by using the rail 9a as a stiffener, the rigidity in the vertical direction is increased, and the crack of the concrete 7 accompanying the generation of tensile stress and the deflection of the beam 3 itself accompanying the generation of compressive stress are suppressed. The structure of the beam 3 is compared with the conventional structure in which the number of the upper and lower reinforcing bars 4 and 5 is increased and the cross section of the beam 3 is formed larger for the purpose of increasing the vertical rigidity. Although it has the same structural performance, it is low in cost and has good workability. Furthermore, when the beam 3 is formed in a long span and applied to the frame structure 1, the internal space of the structure is reduced. In addition, the structural performance of the structure itself, such as proof stress and stickiness, can be improved.
[0021]
The configuration for increasing the vertical rigidity of the beam 3 using the rail 9a as described above is not limited to the reinforced concrete beam 3, but can be applied to the steel beam 3. Below, the example of the steel beam 3 which raised the rigidity of the perpendicular direction using the rail 9a is shown.
[0022]
As shown in FIG. 3 (a), the beam 3 fixes a steel frame 10 made of H-shaped steel extending horizontally so as to connect adjacent columns 2, and the steel frame 10 and the columns 2 are fixed. It is comprised by the fixing member 11 to do. Since the beam 3 tends to generate a tensile stress in the vicinity of the lower surface and in the vicinity of the central portion in the longitudinal direction, the rail 9a is fixed to a portion where the tensile stress is easily generated via fixing means such as welding. .
The railway rail 9a may be fixed at any position as long as it is in the vicinity of the lower surface of the steel frame 10 where tensile stress is likely to occur and in the vicinity of the central portion in the longitudinal direction. Below, the example which concerns on the adhering position of the rail 9a is shown.
[0023]
As a first example, as shown in FIG. 3 (a), the rail 9a extends in parallel with the steel frame 10 on the mating surface with the web 10b at the lower flange 10a of the steel frame 10. Has been placed. At this time, as shown in FIG. 3B, the rails 9a are arranged in pairs with the steel frame 10 with the web 10b interposed therebetween.
[0024]
As a second example, as shown in FIG. 4A, the rail 9a is parallel to the steel frame 10 on the surface facing the web 10b at the lower flange 10a of the steel frame 10. It is arranged to extend. At this time, as shown in FIG. 4B, the rail 9a is disposed so as to be coaxial with the web 10b in the vertical direction with respect to the steel frame 10.
[0025]
As a third example, as shown in FIG. 5A, the rail 9 a is arranged on the side end surface of the lower flange 10 a of the steel frame 10 so as to extend in parallel with the steel frame 10. At this time, as shown in FIG. 5B, the rails 9a are arranged in pairs on both side end surfaces of the lower flange 10a.
[0026]
The steel-framed beam 3 having such a structure is disposed near the central portion in the longitudinal direction at the lower part of the beam 3 where the rail 9a tends to generate tensile stress when a vertical load is applied. Since the rigidity in the vertical direction is increased by functioning as a rigid material, even when it is configured with a long span, the amount of deformation when a vertical load is applied can be greatly suppressed, and the proof stress, deformation capacity, etc. The structural performance of the beam 3 itself can be greatly improved.
[0027]
In the present embodiment, the reinforced concrete structure and the steel structure beam 3 are used as an example of the horizontal structural member. The rail 9a can be applied to any of the horizontal structural members as a stiffener that increases the vertical rigidity.
[0028]
By the way, the means for improving the structural performance such as proof stress and stickiness with respect to the structure including the long span frame structure 1 is not limited to the configuration for increasing the vertical rigidity of the beam 3 itself as described above. A mechanism capable of controlling the deformation in the vertical direction, for example, a configuration in which a tensile material is added to the beam 3 is also conceivable. Hereinafter, details of a configuration in which the used rail 9b functions as a tension member and is added to the beam 3 will be described.
[0029]
As shown in FIG. 6 (b), the beam 3 is composed of a car rebar 8 composed of an upper rebar 4, a lower rebar 5 and a rib 6, and a concrete 7 in which the car rebar 8 is embedded. . As shown in FIG. 6 (a), a tensile material made of the used rail 9b extends horizontally in the longitudinal direction inside the car rebar 8 on the beam 3, and the adjacent pillar 2 It is arranged so that it can be bridged. As shown in FIG. 6B, a plurality of railway rails 9b functioning as tension members are provided with a predetermined spacing in the beam width direction.
[0030]
As shown in FIG. 6A, the rail 9b that functions as the tension member has a sufficiently long member length compared to the distance of one span of the adjacent pillars 2 on which the beams 3 are bridged. The longitudinal intermediate portion 9ba located inside the beam 3 is bent in a so-called arc shape, for example, a parabola shape projecting vertically downward, a suspended curve shape, or a curve shape similar to these. Has been processed. Further, both end portions 9bb sandwiching the arc-shaped intermediate portion 9ba which is bent in the arc shape are partially bent so as to extend vertically downward, and are parallel to the longitudinal direction of the column 2. It has become a shape.
[0031]
The railway rail 9b functioning as a tension member having such a configuration resists the deformation of the beam 3 by resisting the deformation of the beam 3 with a tensile rigidity when a vertical load is applied to the beam 3. It is. In general, a steel material such as a used rail 9b does not increase in deformation in a stress state during normal use. Therefore, the expected tensile stress is applied to the railway rail 9b in a state of being bent into an arc shape such as a parabolic shape, a suspended curve shape, or a curved shape similar to the above-described vertical downward convex shape. If the railway rail 9b is disposed at an appropriate position inside the beam 3 so that a sufficient cross-sectional area capable of withstanding the rail is secured, and bending deformation does not occur in the railway rail 9b, the railway rail 9b Even if the beam 3 functions as a tension member for the beam 3 and is formed in a long span, the deformation in the vertical direction can be controlled.
[0032]
At this time, when a vertical load is applied to the beam 3, a large tension is generated in the vicinity of the column 2 on the rail 9b. However, as described above, both end portions 9bb of the rail 9b are formed in a shape parallel to the longitudinal direction of the column 2 and are accommodated inside the column 2 to form the concrete constituting the column 2. 7 is established. For this reason, the tension acting on the rail 9b can be transmitted to the concrete 7 constituting the pillar 2 by supporting pressure.
[0033]
In addition, since the said rail 9b which functions as a tension | tensile_strength does not expect the adhesion stress with the concrete 7 which comprises the beam 3, the process of making the surface of this railroad rail 9b into a rough surface etc. is unnecessary.
In addition, as shown in FIG. 7, in the frame structure 1 including a continuous span beam in which the beam 3 is continuously arranged in the horizontal direction across the column 2, the railway provided in each beam 3. The opposite end portions 9bb of adjacent rail rails 9b are not bent with respect to both end portions 9bb sandwiching the longitudinal intermediate portion 9ba of the rail 9b which is bent in an arc shape. Are fixed and continuous through fixing means such as enclose welding. With such a configuration, the tension of the rail 9b generated in the vicinity of the pillar 2 can be converted into the axial force direction to the pillar 2.
[0034]
In addition, the used railway rail is not only a horizontal structural member represented by the beam 3 and a structural member such as a tensile member, but also a compression member 12 constituting a vertical structural member represented by a column or the like. Is also conceivable. Below, the structure of the compression material 12 using the used railway rail 9c is explained in full detail.
[0035]
The compressed material 12 is a member that receives a compressive force in the direction of the material axis. In the present embodiment, as shown in FIG. 8, a plurality of rails 9c are bundled so that the cross section in plan view is H-shaped. In combination, they are fixed through fixing means such as welding.
In this way, by bundling and fixing a plurality of railway rails 9, the compression material 12 having a high rigidity in the material axis direction and having a large cross section of a desired size can be configured.
In addition, the combination at the time of bundling does not necessarily need to be an arrangement in which the cross section is H-shaped, and may be formed in any cross-sectional shape. Moreover, what is necessary is just to adjust freely the quantity to bundle and to ensure desired rigidity.
[0036]
Such a compression member 12 using the rail 9c is not only bundled and fixed together by a plurality of rails 9, but for example, as shown in FIG. 9, it is bent at a certain interval in the length direction. Alternatively, the rail 9d that is formed of lattice and the rail 9c that is not processed may be bundled and combined and fixed through fixing means such as welding to form a so-called assembly compression material 13.
[0037]
In the following, a case where the compressed material 12 using the rail 9c is taken as an example and applied to a vertical structural member of an underground building is shown.
FIG. 10 shows a construction method for construction of a timber pillar that realizes shortening of construction period and reduction of construction cost by simultaneously constructing both the underground structure and the upper structure constructed on the ground in response to the enlargement of the construction work. is there. This construction method inserts the lower end portion of the upper steel column 15 of the superstructure constructed on the ground inward when constructing the steel vertical structure member 14 constituting the underground frame constructed in the ground. The upper steel column 15 and the underground vertical structural member 14 are constructed as an integral structure.
Here, it is necessary for the underground vertical structural member 14 to support the upper steel column 15 and to arrange a structural column for transmitting the vertical load of the upper structure to the ground, and to make a steel reinforced concrete structure. The compression material 12 is used for the column.
[0038]
Thus, by using the compression material 12 for the structural pillar, the compression material 12 has a configuration in which a plurality of rails 9 are bundled. Therefore, compared to the case of using a normal steel material, a desired amount of rigidity is achieved. Since it is easy to ensure and there is no need to newly manufacture a steel material intended for use as the compression material 12, the cost can be greatly reduced.
Further, by using the compressed material 12 in which the rail 9c is bundled on the structural pillar, the cross-sectional shape can be easily formed into a desired shape at the site, so that the workability is good and the desired shape is achieved. Because it can be molded, there is no restriction when designing underground structures.
[0039]

Since it is possible to stiffen the vicinity of the upper end surface where compressive stress is likely to occur when the is applied, it is possible to suppress the deflection of the horizontal structural member.
[0042]
In this way, by using the used railroad rail as a stiffener, the rigidity in the vertical direction is increased, and cracks in the concrete due to the occurrence of tensile stress and deflection of the horizontal structural member itself due to the occurrence of compressive stress are suppressed. Compared to the conventional structure, the number of upper and lower bars is increased and the cross section of the horizontal structural member is made larger for the purpose of increasing the rigidity in the vertical direction. Although it has the same structural performance, it is low in cost and has good workability. Further, when the horizontal structural member is formed in a long span and applied to a frame structure, the internal space of the structure is reduced. Therefore, it is possible to improve the structural performance of the structure itself, such as proof stress and stickiness.

The horizontal structural member according to claim 3 is a horizontal structural member that spans between adjacent vertical structural members and forms a frame of the structure together with the vertical structural members, and connects the adjacent vertical structural members. And a steel member extending horizontally, and provided at each of both ends of the steel member, and having a fixing member for fixing the steel member to the vertical structural member, in the longitudinal direction near the lower end of the steel member. A used railway rail arranged in parallel with the steel frame is fixed to the vicinity of the central portion through fixing means.
[0044]
As a result, the used railway rail is arranged in the vicinity of the central portion in the longitudinal direction of the steel-structured horizontal structural member, and the rigidity in the vertical direction is increased by functioning as a stiffener. Even in this case, the amount of deformation when a vertical load is applied can be greatly suppressed, and the structural performance of the horizontal structural member itself, such as proof stress and deformation capability, can be greatly improved.
[0045]
According to the tension member according to claim 4, it is arranged so that the longitudinal direction intermediate part is located inward of the horizontal structural member that spans the adjacent vertical structural member and forms the frame of the structure together with the vertical structural member. It is made of used railway rails extending horizontally so as to bridge the adjacent vertical structural members, and a longitudinal intermediate portion located inward of the horizontal structural members is formed in an arc shape. Molded.
[0046]
Thereby, when a vertical load acts on the horizontal structural member, the used railroad rail resists the deformation in the vertical direction of the horizontal structural member with tensile rigidity, and it is possible to suppress the deformation of the horizontal structural member. Further, even when the horizontal structural member is formed in a long span, it is possible to control the deformation in the vertical direction.
[0047]
According to the tensile material of claim 5, the both ends of the railway rail sandwiching the longitudinal intermediate portion formed in an arc shape are formed so as to extend in the vertically downward direction, The horizontal structural member is accommodated inside the adjacent vertical structural member. As a result, it is possible to smoothly transmit the tension acting on the used railroad rails to the concrete constituting the vertical structural member by supporting pressure.
[0048]
According to the tension member according to claim 6, the rails disposed inside each of the plurality of horizontal structural members disposed continuously in the horizontal direction with the vertical structural member interposed therebetween are adjacent end portions. The two are fixed by the fixing means and are continuous.
