Description

  The present invention relates to a concrete lampway structure having a frictional connection structure constructed adjacent to a building body so that a large vehicle can directly enter each floor of the building body which is a distribution facility such as a distribution center or a warehouse. Is.

  Buildings with lampways in this type of logistics facility are well known or known. The well-known or publicly known general building body is often reinforced concrete (RC), steel-reinforced concrete (SRC) or prestressed concrete (PC) in order to increase strength. On the other hand, the rampway building, which is an approach for entering the vehicle, has been made of steel because of its merit of being lightweight and easy to assemble on site.

  As an example, as a known structure according to the prior art, a seismic isolation device is arranged and connected between a steel pipe pile that penetrates the ground and serves as a foundation and a large beam on the lowest floor of the building body, and each floor of the building body. There are two ramps (rampways) for moving the vehicle up and down, and a seismic isolation building (base isolation warehouse) connected to the building body with a seismic isolation device under the slope. (Patent No. 3899354).

  According to this base-isolated building, it has been explained that the pillars and beams of the building body are precast and fastened by prestressing with PC steel wire. Since it is not explained at all, it is necessary to admit that the construction of the slope portion is a steel structure conventionally employed.

  Steel frame lampways have strength but low rigidity, so if they are subjected to horizontal forces such as shaking or vibration when driving large vehicles or strong winds or earthquakes during use, they will cause excessive deformation and bolts in the joints. Conventionally, buildings that are not integrated with an expansion joint between the steel frame lampway and the main body of the building are prone to breakage, so that only the vertical load is applied to the steel frame lampway and the horizontal load is adjacent to the building. It has a structure that makes the main body bear. As a result, since the structural frame of the building main body bears up to the horizontal load of the lampway, the member cross section and the amount of steel used increase, which inevitably increases the cost.

  In addition, when the lampway building frame is made of concrete such as RC or PC, when the lampway and the building body are integrated without providing an expansion joint, compared to the conventional steel frame lampway The rigidity of a concrete lampway is considerably high, and when a horizontal load due to an earthquake or the like occurs, an excessive horizontal force is transmitted from the building body side to the rampway side, which causes a large shear force to be applied to the lampway column members. There is a problem that it occurs.

  In order to solve the above problems, it is conceivable to provide an expansion joint between the lampway and the building body. The expansion joint is disclosed in the prior art. For example, it is not provided between the building body and the lampway, but as an expansion joint in a concrete structure according to the prior art, the clearance formed on the ground of the outer periphery of the base isolation building is closed with a base isolation cover In the expansion joint, a fitting recess is formed on the building housing side of the clearance, and a protrusion is formed on the building housing side of the seismic isolation lid, and the protruding portion is rotated within the fitting recess. The side of the seismic isolation lid on the building housing side is formed into a tapered surface that swells upward so that it can move, and the side of the outer peripheral side of the seismic isolation lid is tapered outward An expansion joint in which an angle metal fitting is attached, and a sliding inclined portion in which the tapered portion is slidably contacted with the floor portion on the outer peripheral side is formed (Japanese Patent Laid-Open No. 2010-121267).

  In the expansion joint according to this known technology, the taper part of the angle hardware is pushed up by the sliding inclined part by the horizontal force at the time of the earthquake, and a step is generated between the ground and the ground. If the lid is restored to its original position, the strength can be secured to the extent that the vehicle can run on the lid, and there is no need for a separate member for the joint with the building side. It can be connected just by placing it on the top.

Japanese Patent No. 3899354 JP 2010-121267 A

Conventional steel slopes (rampways) have the following problems.
1. The steel members of the pillars and beams that make up the slope (lampway) are manufactured at the factory, are brought into the field, and are connected and joined together by bolts and welding means. Most of them are connected by bolts to simplify and improve the efficiency of field work. As a matter of fact, the concrete frame (columns and beams) of the building body is elastically deformed by its own weight and construction load during construction, and in particular, in the case of a PC structure, the prestress introduced causes elastic deformation of the columns and beams. The pillars on each floor have different amounts of elastic deformation due to different loads. However, because the accuracy of connecting and joining with steel frame members and bolts is required in millimeters, it is impossible to follow the amount of elastic deformation of the building body during construction, so a slope is attached to each floor of the building body at the same time. Cannot be built.
In addition, when steel structures are integrated mainly by connecting and joining with bolts, they cannot be self-supported until the entire building is completed, so they are supposed to be built depending on support work and support. However, because the process of the building body is generally long, if a steel slope is constructed for each floor of the building body, it will not be able to be constructed continuously and will wait for the progress of the building body construction on each floor. Work and support are wasted, leading to high costs.
In order to solve the above-described problems, conventionally, after the structural frame of the building body is completed, the construction work of the steel frame slope is performed. In short, there is a problem that it cannot be performed simultaneously with the construction of the building body.

  2. Steel structure slopes are strong but low in rigidity, and are therefore subject to vibration during the period of use and are always subject to vibrations due to the passage of a large vehicle, so that excessive deformation and loosening or breakage of bolts at joints / joints are likely to occur. In order to always maintain a normal use state, since it is necessary to perform maintenance frequently, there is a problem that maintenance work and running costs are required.

  3. The slope (rampway) is generally circular, but in the case of steel structure, it is difficult to bend the steel beam into a curved shape (arc) in the circumferential direction. However, the external shape of the constructed slope has a broken line shape, and the aesthetics are impaired, and the asset value as a building is also lowered.

  4). Since the slope (rampway) goes up gradually from the ground (ground) toward each floor with a gentle slope, a plurality of short pillars are formed in the structure in the section starting from the ground. For this reason, a steel structure is adopted because it is possible to easily eliminate the formation of a short column by a rigid joint by connecting and joining with a steel structure bolt, and to avoid shear fracture. By the way, RC structure is a reinforcing steel joint, and precast PC structure is a PC steel material, and when using crimp bonding, it is difficult to form a pin joint in the joining of columns and beams, and short columns cannot be eliminated. There is a problem. It is necessary to deal with a special structural treatment for the short column by, for example, providing a concrete wall on the side of the column and causing a shear force to be applied to the wall to eliminate the short column problem. However, the provision of the wall causes a new problem that it takes labor and cost. Further, as another method, it is necessary to provide an expansion joint between the building body and the lampway so as not to cause a large shearing force to be generated in the column member, and to cope with it.

  However, if the upper structure of the lampway is made of concrete with the building body and an expansion joint is provided between the building body and the lampway, the structure body part of the building body and the lampway separated by the expansion joint In order to avoid collisions even when different deformations occur, it is necessary to provide a large clearance in addition to the amount of expansion and contraction that can always occur due to temperature changes, in addition to deformation due to earthquake motion, strong winds, etc. When combined, it becomes necessary to further increase the clearance. However, there is a need for a joint cover that can cover large clearances and that can withstand large weights and that can withstand heavy weight and has little deformation and strength. Not only is it costly, but it is easily damaged by vibration and shaking of a large vehicle at all times, so maintenance is required to maintain its normal use, and maintenance and labor costs are reduced. It also has the problem of hanging.

  Furthermore, like the expansion joint shown in the above-mentioned known technique, the clearance between the outer periphery of the base isolation building and the ground is closed with a base isolation lid. Since the part is a configuration where the outer peripheral side of the lid is flipped upward by the sliding inclined part and a step is generated between the ground and the structure, when this configuration is adopted for the clearance between the building body and the lampway, When an unforeseen earthquake occurs while the vehicle is running and the outer periphery of the lid is flipped up, there is a risk that the lid may be damaged or jumped off by the tires, causing dangers. .

  Therefore, the present invention can be constructed by simultaneously constructing the building body and the structural frame of the lampway with a concrete structure and the like, and an expansion joint is provided between the lampway and the building body. A new expansion joint connection structure that can set the clearance significantly smaller than the expansion joint structure of the previous model, and the lampway is a PC seismic isolation structure that provides super durability and eliminates the need for maintenance and repairs. The object is to provide a building body structure together with a more rational and economical lampway structure.

As a specific means for achieving the above object, the present invention is constructed in a spiral shape adjacent to a building main body and connected to each level with a predetermined gradient from the foundation to the required floor of the building main body. A rampway structure including an upper structure case, wherein the upper structure case is a ramen structure formed of columns and beams made of concrete, and is provided between the building body and the rampway structure. An expansion joint is provided with the required clearance. In the expansion joint, the friction connection member provided on the building body side and the friction connection member provided on the lampway building side are frictionally connected with the required crimping force. There is formed, the frictional connection member are both well as arranged in a state of superposition on the surface contact with the upper and lower formed cantilevered, superposed said friction A hole for inserting a tensioning material that applies the required crimping force in the vertical direction of the connecting member is formed, and the tensioning material is inserted into the hole, and both ends thereof are fixing members composed of an anchor plate and a fastening material. In the hole, a loose hole is formed on at least one friction connecting member side of the hole, a sliding member is disposed between the fixing member on the loose hole side and the friction connecting member, and the friction connection is Up to a predetermined horizontal force, the frictional connection member does not move relative to the frictional force due to the static frictional force, and when the predetermined horizontal force is exceeded, the frictional connection force between the frictional connection members and the fixing portion on the loose hole side The present invention provides a concrete lampway structure characterized in that the clearance can be reduced by adopting a sliding connection in which the sliding member moves relative to the friction connecting member .

In the present invention, the columns and beams are PC columns and PC beams mainly formed of precast concrete, and the PC columns are used for receiving beams at a height corresponding to a predetermined gradient at the junction of the column beams. The jaw is formed in a protruding manner, the joint between the PC column and the end of the PC beam is filled with a joint material, and the PC steel material is tension-fixed to form a PC joint integrally. A PC crimp pin joint is formed in a predetermined portion of the section, with the PC steel material being a single-level wiring, and in the gap, the joint material is filled only on the wiring side, and the non-wiring side is a void joint ; The beam on the inner and outer peripheral sides of the PC beam is formed in a curved shape that is concentric with a circular lamp in the longitudinal direction; at least the PC beam on the outer peripheral side on the inner and outer peripheral sides, Eyes to the bottom It was extended were part; between and the foundation and the upper structural framework, the seismic isolation device are interposed, is intended to include as an additional requirement.

The concrete (seismic isolation) lampway building according to the present invention has the following effects.
1. By providing an expansion joint that is connected as a frictional connection with the required crimping force between the building body and the lampway building, a frictional connection that prevents the frictional connection member from moving relative to the specified horizontal force due to the static frictional force. The building body and the lampway structure are integrated and no relative deformation occurs. When the predetermined horizontal force is exceeded, the frictional connection member moves relative to the frictional force due to the dynamic frictional force, and the relative deformation occurs only after the building body and the rampway building are separated. It can be made very small. In other words, since the structural mechanism that responds to the relative deformation between the building body and the rampway structure due to horizontal force is divided into two stages, first, the building body and the rampway structure up to a predetermined horizontal force. In order to prevent relative deformation, frictional connection is used. When a predetermined horizontal force is exceeded, relative deformation is allowed and sliding connection using dynamic frictional force is used. Therefore, there is an excellent effect that the required clearance between the two can be remarkably reduced as compared with the conventional case.

  2. By establishing a friction connection between the building body and the rampway structure, the frictional force generated between the frictional connection members is preset by the balance of rigidity and proof strength of the building body, the lampway structure, and the structural frame. The shear force transmitted to the rampway building can be controlled, and the horizontal force acting on the building can be distributed in a balanced manner between the ramp and the building body. As a result, in the case of a lampway structure that is conventionally made of steel, it is possible to eliminate the burden of the horizontal force on the building body. In addition, when the rampway structure is made of concrete, it is possible to avoid an excessive horizontal force from being transmitted from the building body to the lampway structure, and together with a rational and economical lampway structure, A structure can be constructed, and a lampway and a building body can be rationally designed as separate structures.

  3. Since conventional steel structure lamps are built after the structural frame of the main body of the building is completed, in particular, since all the equipment and components used for the construction of the main body of the building must be relied on a crane, Costs are incurred. In comparison, the precast member can be built at the same time as the main building by using the PC crimping joint method on the site, so the vehicle can be loaded on each floor during construction and directly loaded. Workability is greatly improved.

  4). Since concrete is easier to shape than steel frame members formed with straight lines, concrete lampway buildings built using precast concrete members formed with curves are not only the appearance of lampway buildings but also the appearance of lampway buildings. Asset value can be improved.

  5. PC crimp pin bonding can eliminate short column formation and avoid brittle shear failure.

  6). By extending the blindfolds that conceal the beam receiving jaws of the PC pillars to at least the PC beams on the outer periphery (circumferential direction), it is possible to maintain a high aesthetic appearance of the lampway building.

  7). Since the seismic isolation structure that combines the seismic isolation method and the concrete rampway building using frictional connection can suppress the relative deformation between the rampway building and the building body, the rampway construction by the seismic isolation device It is possible to prevent the occurrence of excessive relative deformation between the object and the building body, and an inexpensive and optimal seismic isolation structure can be constructed. In addition, compared to the case where the upper housing structure of the rampway structure is made of steel, the rigidity is higher and vibrations can be suppressed. Further, when the upper housing structure is made of PC, after the earthquake, the PC With the restoring force, the PC lamp structure returns to its original state and no residual deformation occurs. For earthquakes, the seismic isolation effect of the seismic isolation device and the earthquake resistance / seismic effect of the PC structure With the synergy effect, it will be possible to deal with a massive earthquake with a seismic intensity of 7 class.

  8). Conventional steel lamps (slopes) are always subject to vibration from large vehicles during the service period, and not only the lamps themselves, but also the connecting parts between the lampway building and the building body are prone to breakage. Maintenance and repair are required. On the other hand, the PC (seismic isolation) lampway building of the present invention has super durability and is connected by an expansion joint having a very small clearance, and thus exhibits various excellent effects such as no need for maintenance.

  The present invention will be described in detail based on a plurality of illustrated embodiments. First, the whole building structure and the basic part in the physical distribution facility shown in FIGS. 1 to 5, the physical distribution facility is composed of a building body 1 and a rampway structure 2 constructed as prestressed concrete (PC), each of which includes a foundation A and an upper frame structure (structure). It is assumed that a frame B) and a seismic isolation device 9 provided between them are provided. The upper structural frame B of the lampway building 2 has a ramen structure formed by concrete columns 3 and girder 4 and is mainly made of precast concrete with girder 4 made of cast-in-place concrete at the bottom of the first floor. It is composed of the formed PC pillar 3 and the PC girder 4, and a circular lampway building 2 is separately and independently constructed adjacent to the building body 1.

  As shown in FIGS. 1 and 2, a pile 6 is driven into the ground 5 at a position where the PC pillar 3 is erected, and the head of the pile 6 is connected by a foundation slab 7. Further, a pedestal portion 8 is integrally formed on the head of the pile 6, and a footing 10 is attached to the pedestal portion 8 via a seismic isolation device 9, and the footing 10 is adjacent to the lowermost floor cast-in-place concrete. The small beams 12 are arranged between the large beams 4, and a floor slab 11 on the first floor is formed on the upper surface. The footing 10 is provided with PC pillars 3 of the building body 1 and the lampway building 2, and each pillar is tension-connected in a standing state by a PC steel material (not shown) disposed therein. It is fixed. In FIG. 2 (a), the floor of the first floor is formed about 1m higher than the ground so that rainwater does not enter the floor of the building. In FIG. 2 (b), The surrounding area of the building is stabilized with respect to the floor of the first floor by placing the embankment 5a in the required range (area) without placing the height of about 1 m as a space part. May be adopted.

  As an example of the entire building relating to the distribution facility, as shown in FIG. 3 and FIG. 4, for example, a 6-story building main body 1, and a circular and spiral lamp adjacent to the building main body 1 is used. The way building 2 is constructed separately and independently, and the ramp way building 2 is constructed so that a large vehicle can climb from the second floor part of the building body 1 to each floor of the fifth floor (predetermined floor) part. The way building 2 is preferably constructed on the side surface on the short side of the building body 1 and is used for climbing and descending. In addition, you may provide the lampway building 2 in two places separately for climbing and descending. Further, as shown in FIG. 5, the upper floors above the second floor are provided with a plurality of small beams 12 between the PC large beams 4a, 4b, 4c disposed between the PC pillars 3, respectively. A floor slab made of a composite floor slab is formed on the upper beams 4a, 4b, 4c and the upper beam 12.

  The lampway building 2 according to the present invention will be described with reference to FIGS. The upper structural frame B of the lampway building 2 has a ramen structure formed by concrete columns 3 and girder 4 and is mainly made of precast concrete with girder 4 made of cast-in-place concrete at the bottom of the first floor. The PC pillar 3 formed and the PC beams 4a, 4b, 4c are constructed in a circular and spiral shape. For the PC pillar 3 made of precast, all the pillars including the building body 1 are A “chin column” which can be said to be the brand product of the applicant himself is employed, and precast PC beams 4a, 4b and 4c are mounted on the jaw. Therefore, as shown in FIG. 6, the portion of the first floor is similar to the building body 1, for example, a pile 6 provided on the inner side and the outer side with an appropriate interval in a circular shape along the shape of the lampway building 2. Between the outer footing 10a and the inner footing 10b, which are respectively attached to the head of each of the two through the seismic isolation device 9, are connected adjacent to each other, and a lowermost large beam connecting the outer side and the inner side is disposed. Has been.

  In this case, the lowermost beam 4 (also referred to as an underground beam) on the first floor is formed by being integrally connected to the footings 10a and 10b by on-site RC, SRC, on-site PC, or the like. A small beam 12 is disposed between the large beams 4 connecting the two to form a floor portion on the first floor. Furthermore, the PC pillar 3 formed of precast concrete on each footing 10a, 10b is tension-connected (not shown) with PC steel and attached in an upright state. In addition, the part shown with the code | symbol 14 is the flat entrance / exit passage which enters the building main body 1 and the lampway building 2 of the 1st floor, and flat entrance passages 14a, 14b, ... are formed with the substantially same positional relationship for every floor. The entrance / exit passage is configured to be connected to a main passage 15 provided on one side of the long side of the building body 1, but the building body 1 and the lampway building 2 are separate and independent. 1 and 5, as shown in FIGS. 1 and 5, there is a required space between the main passage 15 of the building body 1 and the entrance passages 14, 14a, 14b,. The expansion joints 16 are provided in these spaces, which occur on each floor from the first floor to the fifth floor.

  In the ramp way building 2, as shown in FIG. 7, a rising part 17 is formed with a predetermined slope from a flat passage 14 on the first floor as a rising part that climbs from the first floor to the second floor part. In order to maintain the gradient, the PC beams 3a, 4b, and 4c are sequentially tensioned and fixed between the PC columns 3, and the small beam 12 is installed with the required gradient between the PC beams 4c to form a flat passage on the second floor. Form up to 14a. In addition, the connection part (access part) from the 2nd floor to the 3rd floor, the 3rd floor to the 4th floor, and the upper floor is constructed with substantially the same configuration. In this case, the inner and outer peripheral sides of the lampway building 2 formed in a circular and spiral manner, that is, the outer peripheral side large beam 4a and the inner peripheral side PC large beam 4b are concentric with the circular lamp in the longitudinal direction. It is formed in a curved shape (arc shape) and a standing shape (rising shape) with a required height that should be called a handrail. This shape will be described later.

  In this way, the column beam joint portion between the PC pillar 3 and the PC large beams 4a, 4b, and 4c is tension-fixed with PC steel (not shown), and is integrally formed by PC pressure bonding. By constructing the superstructure housing B, as shown in FIGS. 8 to 9, a vehicle approach approaching a predetermined gradient spirally from the first floor to the second, third and required floors in sequence. It is formed. In this case, the PC beam 3 and the PC beam 4a, 4b, 4c are basically rigidly bonded to each other by tightening the PC steel to fix the PC steel material. Since the column is raised from the flat part of the first floor with a predetermined gradient, the column length between the beams at the upper and lower ends, except for the columns with the concrete wall 30, in the plurality of columns near the initial position of the rising, The length of the column that can be freely bent and deformed between them (called the distance between the main fulcrums) has become a substantial column length, which is extremely shorter than the cross-sectional dimensions of the column. Inevitably, it becomes the short pillar 3a. Further, as shown in FIG. 10, since the rampway building 2 is formed in a circular spiral shape, centrifugal force is inevitably generated in the traveling vehicle due to the rotational motion, and the vehicle falls in the outer peripheral direction. In consideration of eliminating the action of the centrifugal force, the PC girder 4c installed in the width direction (radial direction) for forming the traveling road 27 is in the inner (circular center) direction. It is attached with a slight inclination.

  As shown in FIG. 11 (a), when the joint between the short column 3a and the PC large beam 4 is a PC press-bonded rigid connection 18 as in the normal length of the PC column 3, the column beams at the upper and lower ends. Since bending rotation is constrained at the upper and lower ends by the joint portion, the column formed therebetween becomes the short column 3a. The short column is the most unfavorable failure type in terms of structural design because shear force concentrates prior to bending failure and deformation capability is extremely poor and brittle shear failure is likely to occur. Therefore, in order to avoid shear fracture, as shown in FIG. 5B shown by the arrow A, the connecting portion between the column that has become the original short column 3a and the PC large beams 4a, 4b, and 4c is used as the PC crimp pin connection 19. Thus, the length between the column-beam rigid joints (the range indicated by 3 in the lower part of the figure (b)) becomes the substantial length of the PC column 3, and the length that the column can be freely bent and deformed becomes longer. The formation of 3a was eliminated. That is, the normal long PC column 3 and the PC large beams 4a, 4b, and 4c are made into the PC crimping rigid joint 18, and the short column 3a and the PC large beams 4a, 4b, and 4c are made into the PC crimping pin joint 19, thereby making the short column The problem of shear fracture of the column was solved by eliminating the formation of 3a.

Therefore, a specific joint structure between the PC pillar 3 and the PC girder 4 will be described with reference to FIGS. First, as shown in FIG. 12, the PC column 3 is a “jawed column”, and a PC steel material 20 that is inserted and disposed inside is connected to a column connecting portion 21 (PC crimping joint between column nodes). In this way, the tension is fixed while being sequentially connected to each floor via the PC steel material connecting portion 22, and the tension is erected and fixed up to the upper floor. The PC pillar 3 is formed with jaws 13a for placing and laying the PC large beams 4a and 4b installed in the circumferential direction with steps corresponding to the angle of the gradient, and in the width (radius) direction. Since the PC girder 4c installed on the side is attached with a slight inclination in the inner (circular center) direction, the jaw 13b on which the end portion is placed has a slightly lower jaw 13b on the inner peripheral side than the outer peripheral side. Each PC girder 4a, 4b, 4c, which is formed low and is placed on each jaw 13a, 13b, is inserted into the upper and lower sides of the inside so that a position above the jaws 13a, 13b and a substantially central portion of the jaws 13a, 13b are formed. The tension is fixed by a plurality of PC steel materials 23 and 24 that are two-stage wirings penetrating therethrough, and joints are formed in the gaps between the PC pillar 3 and the jaws 13a and 13b and the ends of the PC beams 4a, 4b, and 4c. Filled with joint material 25 such as mortar To PC crimping rigid junction 18. However, the PC-bonded rigid joint of the column beam is not limited to the one formed by the two-stage wiring shown in the figure, and may be a multi-stage wiring if necessary. In other words, the wiring of the PC pressure-bonding rigid connection is two or more stages. Each step is formed of one or a plurality of PC steel materials.
In order to distinguish the features of the present invention from those of the prior art and to make it easier to understand, in the present invention, the conventional PC crimping joint is called a PC crimping rigid joint, which is a novel PC crimping joint for eliminating short columns that is not available in the prior art. The structure is called PC crimp pin bonding.

  Next, in order to eliminate the short column 3a, a specific PC crimp pin joining structure between the PC column 3 and the PC large beam 4 is mounted on the jaw 13a formed on the short column 3a as shown in FIG. The PC steel beams 4a and 4b are placed in a state where the PC steel material 24 inserted and disposed as a one-stage wiring on the lower side of the PC large beam (on the side of the running ramp 27 formed of a slab) penetrates the jaw 13a. As for the PC girder 4c placed on the jaw 13b, the PC steel material 23 inserted and arranged on the upper side (slab side) of the PC girder 4c penetrates the upper position than the jaw 13b and is fixed in tension. The joint member 25 is filled only in the gap between the short column 3a through which each of the PC steel materials 24, 23 penetrates and the ends of the PC large beams 4a, 4b, 4c, and the gap in the portion where the PC steel materials 24, 23 do not penetrate. Is a PC crimp pin joint 19 as an open joint 26 To.

That is, the above-mentioned PC crimp pin joining is configured as three necessary constituent conditions of using a “chin column” and one-level wiring and empty joints. In short, since the column has a jaw, the beam end of the precast PC large beam can be rotated on the jaw, so that only a shearing force can be transmitted without generating a bending moment. If there is no jaw, the beam end becomes a PC crimp joint and cannot be rotated, so that the above-mentioned PC crimp pin joint cannot be achieved.
In addition, in the PC crimp pin joint structure, in the beam-column joint, it is a basic configuration that one-stage wiring is provided on the side with the slab of the beam and the joint on the non-wiring side is an empty joint.

Therefore, various modifications can be added and changed without departing from the spirit of the invention. For example, the “jawed column” is preferably made of precast as in the case of the large beam, but is not limited thereto, and may be cast-in-place concrete. Although not shown in the figure, the columns with pillars and girder are made of precast, but the panel zone (column and beam joints) is made of cast-in-place concrete, and the columns are made by semi-crimping method (PC steel and rebar) A large beam may be joined.
In the upper frame structure of the rampway building of the present invention, in the case where the PC large beam 4c in the width direction of the traveling roadway 27 (the radial direction of the ramp) is a forward beam in accordance with the above-described purpose, In the upper part, when the PC large beams 4a and 4b on the inner and outer peripheral edge sides (circumferential direction of the ramp) are reverse beams, the traveling road 27 is located below the large beams 4a and 4b, as shown in FIGS. In this way, the PC crimp pin joint 19 (shown by a black circle in FIGS. 7 to 10) is formed at a predetermined portion of the column beam joint portion to eliminate the short column problem.
However, when a concrete wall is attached to the side of the column (column with a wall), the wall bears the shearing force, so the short column is eliminated by the method with the wall. It is not necessary.

  Furthermore, in the present invention, a specific configuration of the PC beams 4a and 4b in the length direction (circumferential direction) will be described with reference to FIGS. Both ends of the PC beams 4a and 4b are placed on the jaw 13 formed so as to protrude from the PC pillar 3, but only by placing the PC beams 4a and 4b on the jaw 13. The protruding jaw 13 is exposed to the outside as it is, and the appearance of the structure is impaired. However, in the present invention, at least the outer portion of the protruding jaw 13 is covered entirely, and the bottom portion of the jaw 13 is also covered so as to cover the outer peripheral surface of the slab disposed as the traveling road 27 on the lower surface of the reverse beam. This is provided with a blindfold 28 that is extended to the end. That is, a sufficient thickness in the height direction for maintaining the strength of the PC beams 4a, 4b is secured to provide a standing handrail portion, and a recess 29 into which the jaws 13 protruding at both ends of the PC pillar 3 are fitted is provided. This is characterized in that the jaw 13 is not exposed to the outside. By configuring in this way, the PC pillar 3 and the PC large beams 4a and 4b of the finished lampway building 2 are in a flush state, and the appearance in appearance is improved.

  Thus, a space portion exists between the main passage 15 of the building body 1 constructed as an independent structure and the entrance / exit passages 14, 14a, 14b... Of the lampway building 2, and an expansion joint 16 is provided in the space portion. A required member is laid on the expansion joint 16 so that the two can approach each other.

  A first embodiment of the expansion joint 16 is shown in FIGS. In this embodiment, as a required member of the expansion joint 16 between the building body 1 and the lampway building 2, friction of a required size (width) provided on the main passage 15 side on the building body 1 side. By applying the required crimping force to the surface contact between the connecting member 31 and the friction connecting member 32 of the required size (width) provided on the entrance / exit passages 14, 14a, 14b ... side on the lampway building 2 side The frictional connection is made substantially.

  That is, as shown in FIGS. 16A and 17, the friction connecting member 31 is placed on the PC beam 4 disposed on the main passage 15 side of the building body 1 at positions that are substantially both sides of the expansion joint 16. In addition to being formed integrally with the friction connecting member 31, an anchor plate and a nut are provided on the base side of a plurality of (2 to 4) tension members (for example, a PC steel bar, a high-strength steel bar, or a bolt) 33. It is embedded so that it does not come out through the dead anchor 34, and is attached with the upper part protruding in a required length, and a plurality of jaws 13c are also integrally formed at a required interval. Further, as shown in FIGS. 16 (b) and 17, a plurality of jaws 13d are integrated with a PC girder 4 arranged on the side of the rampway building 2 on the side where the entrance / exit passages 14, 14a, 14b,. In addition, the friction connecting member 32 is formed at a position overlapping the friction connecting member 31 integrally with the slab which is the traveling road 27 on the lampway building 2 side. A loose hole 35 through which a pair of tendon members 33 is loosely inserted is formed, and a rectangular recess 36 for fixing the tendon member 33 is formed on the loose hole 35, and the loose hole 35 is formed. An upper end portion of the tension member 33 inserted through the anchor plate 38 and a fastening member (for example, a nut) 39 via a sliding member 37 such as a Teflon (registered trademark) member as a sliding means laid on the bottom of the recess 36. In A predetermined crimping force (clamping force) is applied, and the friction connecting member 31 and the friction connecting member 32 which are overlapped are connected by forming a friction connection by a predetermined friction force, and the horizontal direction exceeds the friction force. Only when an external force is applied, the frictional connection member 31 and the frictional connection member 32 are in a sliding connection in which the frictional connection force moves relative to each other, and relative deformation occurs between the building body 1 and the lampway building 2. The required clearance (gap) a in FIG. 16, in other words, the gap a provided between the end of the frictional connection member 32 and the building main body 1 may be provided to be significantly smaller than the conventional one. The friction connecting member 31 and the friction connecting member 32 may be formed integrally with the girder 4 by using cast-in-place concrete. However, both are formed as separate bodies. Further, in place of the dead anchor of the frictional connection member 31, a protruding portion 36 can be provided similarly to the frictional connection member 32, and the tension fixing portion can be formed by the anchor plate 38 and the fastening material 39.

  Further, as shown in FIG. 18, for example, a Teflon (registered trademark) material (sheet) is laid as a sliding material 40 on one jaw 13 c on the building body 1 side located at the expansion joint 16, and the other jaw 13 d. The precast PC beam 12 is placed between the two. On the lampway building 2 side, the precast PC beam is tension-fixed as a two-stage wiring by a plurality of PC steel materials 23, 24, is filled with the joint material 25, and is PC-bonded to the PC beam 4. In this case, the PC beam 12 is placed so that a required gap a is formed between the PC main beam 4 on the building body 1 side, and the slab on the lampway building 2 side on the PC beam 12, that is, The traveling road 27 is formed and integrated, and with respect to the horizontal movement, the end portion side of the PC beam 12 placed on the Teflon (registered trademark) material (sheet) as the sliding material 40 slides. .

Further, as a second embodiment of the expansion joint 16, a case where the friction connecting member 31 and the friction connecting member 32 are formed separately from the building body 1 and the lampway building 2 is shown in FIGS. 19 to 21. It is.
First, as shown in FIG. 19A and FIG. 20, the friction connecting member 31 formed separately is in relation to the PC girder 4 of the building main body 1 at the positions on both sides of the expansion joint 16. A plurality of PC steel wires 41 are PC-bonded rigidly and attached integrally. In this case, a connecting beam 42 is interposed between the PC large beam 4 and the adjacent PC small beam 12 in the building body 1, and a PC steel wire 41 is disposed through the connecting beam 42. The front end side of 41 is fixed to the friction connecting member 31, and the rear end side is firmly fixed to the PC beam 12 so that the friction connecting member 31 is firmly attached to the PC large beam 4. As in the first embodiment, the configuration in which a plurality of tendons 33 are attached is the same.

  Further, as shown in FIG. 19B and FIG. 20, the friction connecting member 32 formed separately from the PC large beam 4 of the lampway building 2 facing the expansion joint 16 is the same as described above. Then, the PC steel wires 43 are used to integrally attach them by means of PC crimping rigid joining. In this case as well, the connecting beam 44 is interposed between the PC large beam 4 and the adjacent PC small beam 12 in the lampway building 2, and the PC steel wire 43 is disposed through the connecting beam 44. The front end side of the PC steel wire 43 is fixed to the friction connecting member 32, and the rear end side is firmly fixed to the PC beam 12 so that the friction connecting member 32 is firmly attached to the PC large beam 4 and the building body A loose hole 35 through which the tension member 33 is loosely inserted is formed, and the tension member 33 is formed in the upper portion of the loose hole 35, as in the first embodiment. The same applies to the point that the rectangular recess 36 for fixing the tension is formed and the point that the tension member is fixed with a constant tension in the recess 36, and the description thereof will be omitted.

  Furthermore, as shown in FIG. 21, for example, a Teflon (registered trademark) material (sheet) is laid as the sliding material 40 on one jaw 13c on the building body 1 side located in the space 16 and the other jaw 13d. The precast PC beam 12 is placed between the two. In this case, the PC small beam 12 is placed so that a required gap a is formed between the PC large beam 4 on the building body 1 side, and the PC small beam 12 is placed on the other side of the rampway building 2 on the other side. Similar to the small beam, the tension is fixed and stabilized by an appropriate PC steel material 23 and the like, and in the horizontal direction, the end portion side of the PC small beam 12 placed on the Teflon (registered trademark) material (sheet) as the sliding material 40 is It slides.

  In any case, the expansion joint 16 provided between the building body 1 and the lampway building 2 constructed independently can be frictionally connected as described in the first and second embodiments. It is frictionally connected by the frictional force between the members 31 and 32. That is, the building body 1 and the lampway building 2 are integrated by the frictional force, and relative to each other at a predetermined horizontal force or less, for example, a moderate earthquake level No deformation occurs. Only when a horizontal force exceeding the maximum static frictional force is applied (applied) when a predetermined horizontal force is exceeded, the frictional connection member moves relative to each other by the dynamic frictional force, and the building body 1 and the lampway building are formed. Therefore, the required clearance (gap) a may be remarkably narrow (small).

  In other words, in the expansion joint, a frictional connection structure that corresponds to the relative deformation between the building body 1 and the rampway building 2 due to a horizontal force in two stages of a static frictional connection and a dynamic frictional connection, up to a predetermined horizontal force Is maintained by friction welding so that relative deformation does not occur between them, and can be dealt with by dynamic friction force only when a predetermined horizontal force is exceeded. Therefore, the clearance between the two buildings can be remarkably reduced as compared with the conventional structure. In addition, when the horizontal force received by a hierarchy differs in a building, it can be designed so that the magnitude | size and shape of a frictional connection member can be changed, or the tension | tensile_strength of the tension material 33 can be adjusted for every hierarchy.

Next, the structural mechanism in the frictional connection between the building body 1 and the lampway building 2 will be described with reference to the schematic diagrams shown in FIGS.
First, in FIG. 22, friction connecting members 31 and 32 in the expansion joint 16 of the building body 1 and the lampway building 2 are disposed, and the frictional force between the two is determined by the tightening of the tension member 33 or the crimping force P due to the tension. F is generated and friction bonded. As is well known, since the magnitude of the frictional force F is determined by the pressure bonding force P and the friction coefficient μ, the friction coefficient is a constant, and the frictional force F is proportional to the pressure bonding force P.

  In addition, earthquakes and strong winds exert a horizontal force (load) on the building, but the magnitude of the force varies depending on the weight, shape, height, etc. of the building. For example, even if an earthquake of the same scale occurs in the same place, the horizontal force applied by the earthquake differs between the building body 1 and the rampway structure 2. Therefore, for the sake of explanation, as shown in FIG. 23, if the horizontal force acting on the lampway building 2 is Qr and the horizontal force acting on the building body 1 is Qb, the building body 1 generally has the lampway. Since the scale and weight are much larger than the building 2, the horizontal force acting on the building body 1 Qb is much larger than the Qr horizontal force acting on the lampway building 2, but it is required If it is within the horizontal force, the building body 1 and the lampway building 2 undergo the same deformation δ in the same direction and in the same direction by the frictional joining of the friction connecting members 31 and 32. The required horizontal force in the present invention is set in advance according to the larger one of the horizontal force Qb acting on the building body 1 and the horizontal force Qr acting on the lampway building 2 due to an earthquake or strong wind. The calculated values of the horizontal forces Qb and Qr can be confirmed in advance.

  In this case, the magnitude of the maximum frictional force Fmax can also be determined by setting the crimping force P in advance as required. In other words, the larger one of “Qb−Fmax” and “Qr + Fmax” shown in the schematic diagram can be confirmed and adjusted in advance by setting the larger one as the predetermined horizontal force. First, up to a predetermined horizontal force, the first stage is set, and the building body 1 and the rampway building 2 are connected by frictional connection so that relative deformation does not occur. Fmax, and the building body 1 and the lampway building 2 are integrally joined by this maximum static frictional force to have the same deformation δ. In short, since the horizontal force Qb is much larger than the horizontal force Qr, the maximum static frictional force Fmax is transmitted to the rampway building 2 side, and the horizontal force borne by the rampway building 2 is Qr + Fmax and the share is shared. To increase. In the other building body 1, the horizontal force that actually acts is Qb-Fmax, and the burden is reduced.

  Next, FIG. 24 will be described as a second stage when a predetermined horizontal force is exceeded. When a predetermined horizontal force is exceeded, relative deformation is allowed and a dynamic friction force F ′ is used as a sliding connection. At that time, the horizontal force borne by the lampway building 2 is Qr + F ′, the horizontal force borne by the building body 1 is Qb−F ′, and relative deformation occurs for the first time. The deformation value is δb−δr = It becomes a. According to this principle, there is no relative deformation until a predetermined horizontal force, and the relative deformation occurs only when the predetermined horizontal force is exceeded. It can be significantly smaller than that.

  In addition, the predetermined horizontal force can be appropriately set by the balance of the structural frame rigidity and the proof strength of the building body 1 and the lampway building 2. For example, it may be a horizontal force that is always generated when a large vehicle travels or a slight vibration occurs due to strong winds, or it may be a horizontal force that is based on a weak seismic intensity of a medium or small earthquake. That is, the value of the predetermined horizontal force can be set by controlling the horizontal force transmitted from the building body 1 to the rampway building 2 together with the relative deformation amount in advance. Without generating large shearing force on the column, formation of the short column can be eliminated and brittle shear failure can be avoided. Accordingly, it may be possible to avoid the lampway building 2 without providing a PC crimp pin joint. In the embodiment of the present invention, the example in which the friction connecting members are arranged on both sides of the expansion joint has been shown. However, the present invention should not be limited to this, and the number of places to be arranged in advance according to the set value of a predetermined horizontal force is increased. Moreover, although the tension material (PC steel bar) is attached to one place to form two pairs (four bars), it can be increased or decreased depending on the set value of the required frictional force. Furthermore, although PC steel bar was demonstrated as a tension | tensile_strength material, it is not restricted to this, For example, you may use either a PC steel wire, a PC steel strand, a high altitude bar steel, or a high strength bolt.

  The embodiment described above is not limited to the configuration of the present invention, and various modifications can be made without departing from the gist of the present invention. For example, it is good also as a PC earthquake-proof lamp, without interposing a seismic isolation apparatus between a foundation and a superstructure housing. In addition, the PC crimp pin joint structure shown in the present invention can be applied not only to lampway structures but also to other structures as a means of eliminating short columns, and the friction connection structure of the expansion joint is independent. It can also be applied to existing buildings that are constructed in this way.

  The concrete lampway building 2 according to the present invention is constructed adjacent to the building main body 1 in a spiral shape that is connected to each floor with a predetermined gradient from the foundation A to the required floor of the building main body 1 from the foundation. A lampway building 2 having an upper structural frame B, wherein the upper structural frame B is a ramen structure formed of columns and beams made of concrete, and the building body 1 and the lampway building An expansion joint 16 is provided between the building 2 and a friction connecting member 31 provided on the building body 1 side and a friction connecting member 32 provided on the lampway building 2 side. By forming the frictional connection with the crimping force, the concrete lampway structure 2 can be constructed independently of the building body 1 at the same time. In can be connected, it can significantly reduce the clearance of the building main body 1. Furthermore, the upper structural frame B is composed of PC pillars 3 and PC beams 4a, 4b, and 4c mainly made of precast concrete, and is integrally PC-bonded by tension fixing of the PC steel material at the column beam joints. In the PC pillar 3, beam receiving jaws 13, 13a, 13b, 13c, and 13d are formed to protrude at a height corresponding to a predetermined gradient, and the beams 4a and 4b on the inner and outer peripheral sides of the PC beam are By adopting a configuration that is formed in a curved shape that is concentric with the circular lamp in the longitudinal direction, the precast member similar to the building main body 1 is subjected to the concrete pressure lamp construction of the present invention by the PC crimping joint method on site. 2 can be built at the same time as the building body 1, and both buildings are frictionally connected by the expansion joint mechanism. The fly on each floor, because allows the direct loading and unloading, and than workability is greatly improved, can be widely used in distribution facilities of distribution centers and warehouses of this kind.

In the present invention, when the upper structural frame of the concrete lampway building is precast prestressed concrete (PCaPC) as the main column beam, the PC steel material arranged on the cross section of the column beam structure member is tensioned. By fixing, prestress is given to the concrete member cross section so that it can resist the assumed load in advance.
The prestress force is an internal force that exists in the member in advance and always acts in the direction opposite to the deformation direction of the member. It is a force that resists when trying to deform, trying to restore a deformed building like a pendulum. This is called a restoring force due to pre-stress, and is a force for returning to the original state at the time of deformation. This effect is referred to as pre-stress damping / damping effect. This damping / damping effect cannot be obtained for RC structures, steel structures, and the like.

Therefore, the PC lamp structure of the present invention is not only a structure having extremely high seismic performance but also a vibration control / damping structure. It is possible to greatly reduce vibrations caused by large vehicles at all times and to suppress deformation during earthquakes. In addition, the PC lamp structure is restored to its original state by a PC restoring force after being constantly subjected to vehicle vibrations or earthquakes, resulting in a structure having no residual deformation.
In addition, the PC lampway structure combined with the seismic isolation method has higher rigidity and less vibration compared to the case where the upper lamp structure is made of steel, and is extremely durable. There is no need. Furthermore, for earthquakes, there is a synergistic effect between the seismic isolation effect of the seismic isolation device and the PC structure's seismic resistance and seismic control effect by the PC crimping joint method, as well as the independently constructed building body and concrete lampway structure Means that frictional connection is achieved by a frictional connection structure that has two stages of functions, so that a large shear force is not generated in the columns of the rampway building, and the short column formation is eliminated and brittle shear failure is avoided. It is possible to cope with a huge earthquake with a seismic intensity of 7 class.
