Description

  The present invention relates to a roof support device that supports a cantilevered roof structure, and a carport including the roof support device.

Conventionally, as a cantilever type roof structure, a carport having an inverted side L-shaped frame and a roof, a ridge protruding from a structure such as a building, and the like are known. The carport will be described as an example. The frame is fixed to a concrete foundation provided on the ground, and a pillar portion extending vertically upward from the foundation, and a beam portion extending in a cantilevered manner from the upper end of the pillar portion to the side. And a roof is placed and supported on the beam portion.
Loads acting on such carports include vertical loads due to their own weight and snow, horizontal loads such as earthquakes and winds, traffic vibrations, etc. Of particular concern are wind pressure and snow accumulation acting on the roof surface. It is. When wind pressure or snowfall acts on the roof surface, a large overturning moment is generated in the foundation via the frame. Therefore, it is necessary to construct a foundation having a shape, size and weight that can resist the overturning moment.

  Construction of such a foundation increases material costs and construction costs, so a structure has been proposed that reduces the tipping moment generated on the foundation by adding auxiliary struts that support the cantilever tip of the roof or frame. (For example, refer to Patent Document 1). The auxiliary strut described in Patent Literature 1 has one end connected to the tip of the beam portion of the frame via a support fitting, and the other end connected to the ground via the support fitting, and acts on the roof surface. A vertical load is directly transmitted to and supported by the ground.

Japanese Patent Application Laid-Open No. 9-221928

  However, since the both ends of the conventional auxiliary strut are connected to the frame and the ground, the vertical load acting on the roof surface is directly transmitted, and a large axial force is generated in the auxiliary strut. There is a problem that it becomes excessive. In addition, a gate-shaped frame is formed by directly connecting the tip of the roof and the ground by the auxiliary support column. However, such a portal frame is more rigid than an inverted L-shaped frame. Since the natural period increases, the natural period is shortened, resulting in inconvenience of being easily affected by vibration. For this reason, there is a problem that the frame and the foundation are repeatedly loaded by relatively small disturbances such as earthquakes, winds, traffic vibrations, etc., and the strength is reduced due to long-term damage accumulation.

  An object of the present invention is to provide a roof support device and a carport capable of improving a supporting force against an excessive load while suppressing a long-term strength decrease.

The roof support device of the present invention connects a cantilever tip of a cantilever type roof structure and a support away from the roof structure to support the tip of the roof structure. A long connection member provided across the tip of the roof structure and the support, and a first connection for connecting one end of the support member and the tip of the roof structure Part, a second connection part that connects the other end of the support member and the support, and a damper device provided on either the first connection part or the second connection part, damper device includes a damping member which exhibits one end relative movement or damping force in accordance with the relative movement of the other end portion and the support of the support member between the distal end portion of the roof structure of the support member , One end of the support member or the other end of the support member A tubular slide member having a larger diameter than the support member slidably provided along the direction, and the support member passes through the slide member and spans the roof structure and the support body. The damping member is interposed between the inner periphery of the slide member and the outer periphery of the support member, and is subjected to a shearing force in accordance with the relative displacement between the support member and the slide member, thereby reducing the damping force. It is characterized by being comprised from the viscoelastic material which exhibits .

According to the present invention, the damping member of the damper device exerts a damping force in association with the relative movement between the support member and the tip of the roof structure or the support, so that the cantilever tip of the roof structure Vibration can be attenuated, and repeated loads acting on the roof structure can be suppressed. Therefore, accumulation of damage to the foundation and base end of the roof structure can be prevented, and the strength can be maintained over a long period of time. In addition, since the load acting on the roof structure is transmitted from the tip of the roof structure to the support body via the damper device and the support member, even if a vertical load such as a large wind pressure or snow load acts on the roof surface. The vertical load can be shared and supported by the roof structure and the roof support device. Therefore, the load does not concentrate on the support member of the roof support device, the axial force generated on the support member can be suppressed, and an economical design becomes possible.
Further, by inserting the attenuation member between the support member and the tubular member having a larger diameter than the support member, the attenuation member can be covered with the tubular member, and the deterioration of the attenuation member is prevented, and the attenuation member is peeled off. Can also prevent. Here, the attenuation member made of a viscoelastic material has the property of being easily deteriorated by ultraviolet rays, but even when used outdoors, it is covered with a tubular member to block the ultraviolet rays, thereby extending the life of the attenuation member. Can be achieved.
Further, when a load exceeding a predetermined value is applied by restricting the slide of the slide member along the axial direction of the support member to a predetermined value or less by the first restricting member and the second restricting member, the load Can be directly transmitted to the support member and supported by the support. Therefore, for loads of the size normally assumed, the load is supported while exhibiting the damping force due to the deformation of the damping member, and for excessive loads exceeding the assumption (for example, gusts, typhoons, heavy snow, etc.) Since a load is directly transmitted from the support member to the support body by the regulating member, a larger support force can be obtained. Further, by restricting the slide of the slide member to a predetermined value or less by the restricting member, it is possible to suppress excessive deformation of the attenuation member, and it is possible to maintain the performance by preventing the attenuation member from being damaged.

At this time, the damper device includes a first restricting member that restricts sliding of the slide member toward one side in the axial direction of the support member to a predetermined value or less, and a slide member toward the other side in the axial direction of the support member. A second restricting member for restricting the slide to a predetermined value or less , wherein the first restricting member and the second restricting member are constituted by a tubular retention tube having a diameter larger than that of the support member, and the support member includes It is preferably fixed .

  According to such a configuration, the damping member made of the viscoelastic material undergoes shear deformation in accordance with the relative displacement between the support member and the slide member, and exhibits a damping force according to the deformation, thereby the roof structure. The vibration of the cantilever tip can be effectively damped. Here, the viscoelastic material exhibits a damping force according to its deformation speed and has the property of converting vibration energy into heat energy, so it absorbs relatively small vibrations and loads acting on the roof structure efficiently. Thus, damage accumulation can be suppressed.

Furthermore, the slide member is preferably Rukoto part of the peripheral direction of the tubular notched be formed with a gap extending along the axial direction.

Further, the damper device Rukoto provided in the first connecting portion is preferred.

  The carport of the present invention is a carport comprising a foundation provided on the ground, a frame fixed to the foundation, and a roof supported by the frame, wherein the frame is perpendicular to the foundation. A column part extending and a beam part extending in a cantilevered side from the upper end of the column part, and a first connection part of the roof support device is provided at a tip part of the beam part or a part of the roof. It is connected.

  According to the present invention, since the repeated load acting on the carport frame and foundation can be suppressed by the roof support device, it is possible to prevent the accumulation of damage and maintain the strength. Long life can be achieved. Furthermore, even if a vertical load such as a large wind pressure or snow load acts on the roof surface, by supporting the vertical load with the roof support device, it is possible to suppress the overturning moment acting on the foundation, Costs can be reduced by simplifying the foundation.

FIG. 6A is a view when an upward load of a predetermined value or less is applied to the roof, and FIG. 6B is a view when a downward load of a predetermined value or less is applied to the roof.
The load equal to or less than a predetermined value is a load applied to the roof 5 during road surface vibrations when the vehicle is passing or during normal rain or wind.
First, FIG. 6A shows a state when a load of a predetermined value or less upward on the roof 5 is transmitted from the first connecting portion 20 to the damper device 40 via the beam portion 4b. At this time, an upward force is applied to the support member 11 and only the reaction force from the damping member 42 is transmitted.

Further, FIG. 7A is a diagram when a load greater than a predetermined value is applied to the roof, and FIG. 7B is a diagram when a load greater than a predetermined value is applied to the roof.
The load exceeding a predetermined value is an excessive load exceeding the assumption applied to the roof 5 in case of sudden weather changes such as gusts, typhoons, and heavy snow.
First, FIG. 7A shows a state in which a load of a predetermined value or more upward on the roof 5 is transmitted to the damper device 40 connected by the first connecting portion 20 by the beam portion 4b. At this time, an upward force is applied from the damping member 42 to the support member 11, and the shear deformation rate of the damping member 42 exceeds 100%, for example, reaches about 200%. Here, since the first restricting member 50 is installed, the tubular member 41 and the first restricting member 50 come into contact with each other, and deformation above the predetermined value above the damping member 42 is restricted and applied to the damper device 40. Since the load is transmitted from the first regulating member 50 to the support member 11 and from the support member 11 to the support body 6, the upward load can be supported by the support body 6 and the ground 2.

Next, FIG. 7B shows a state when a load of a predetermined value or more downward on the roof 5 is transmitted to the damper device 40 connected by the first connecting portion 20 by the beam portion 4b. At this time, a downward force is applied from the damping member 42 to the support member 11, and the shear deformation rate of the damping member 42 exceeds 100%, for example, reaches about 200%. Here, since the second restricting member 60 is installed, the tubular member 41 and the second restricting member 60 come into contact with each other, and the deformation below the predetermined value of the damping member 42 is restricted and applied to the damper device 40. Since the load is transmitted from the second regulating member 60 to the support member 11 and from the support member 11 to the support body 6, the downward load can be supported by the support body 6 and the ground 2.
As described above, when the roof support device 10 includes the damper device 40, when a load within a predetermined value is applied to the roof 5, the load is absorbed by the damping member 42, and a load greater than the predetermined value is applied to the roof 5. The load can be dispersed by the first regulating member 50 and the second regulating member 60 together with the damping member 42.

(2) The damper device 40 can prevent accumulation of damage to the main body base 3 and the frame 4 of the carport 1 and maintain the strength over a long period of time.
(3) Since the load acting on the carport 1 is transmitted from the beam portion 4b to the support 6 via the damper device 40 and the support member 11, a vertical load such as a large wind pressure or snow load is applied to the roof 5. Even if it acts, the vertical load can be shared and supported by the carport 1 and the roof support device 10. Therefore, the load does not concentrate on the support member 11 of the carport 1, the axial force generated in the support member 11 can be suppressed, and an economical design becomes possible.

(4) The damping member 42 made of a viscoelastic material undergoes shear deformation along with the relative displacement between the support member 11 and the tubular member 41, and exhibits the damping force according to the deformation, thereby placing the roof 5 thereon. It is possible to effectively attenuate the vibration of the beam portion 4b.
(5) By inserting the attenuation member 42 between the support member 11 and the tubular member 41 having a larger diameter, the attenuation member 42 can be covered by the tubular member 41, and deterioration of the tubular member 41 is prevented. In addition, peeling of the damping member can be prevented. Moreover, the lifetime of the attenuation member 42 can be extended by covering with the tubular member 41 and blocking ultraviolet rays.

(6) When a load exceeding a predetermined value is applied by restricting the slide of the tubular member 41 along the axial direction of the support member 11 to a predetermined value or less by the first restricting member 50 and the second restricting member 60. The load can be directly transmitted to the support member 11 and supported by the support 6.
(7) For a load of a size normally assumed, the load is supported while exhibiting a damping force due to the deformation of the damping member 42. For an excessive load exceeding the assumption, the first regulating member 50 and By transmitting the load directly from the support member 11 to the support body 6 by the second restricting member 60, a greater support force can be obtained.
(8) Excessive deformation of the damping member 42 can be suppressed by regulating the sliding of the tubular member 41 that is a sliding member to a predetermined value or less by the first regulating member 50 and the second regulating member 60, and the damping member 42. The performance can be maintained by preventing the damage.

(9) Since the repeated load acting on the body foundation 3 and the frame 4 of the carport 1 can be suppressed by the roof support device 10, the accumulation of damage can be prevented and the strength can be maintained. Long life can be achieved.
(10) Even if a vertical load such as a large wind pressure or a snow load acts on the roof 5, by supporting the vertical load by sharing it with the roof support device 10, the overturning moment acting on the foundation can be suppressed. The cost can be reduced by simplifying the main body foundation 3.
