DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an overhanging carport in which a roof is suspended and supported.

[0002]

2. Description of the Related Art An overhanging carport, in which a roof is suspended and supported by a plurality of pillars located on one side thereof, has an end on the eaves side of the roof opposite to the pillars. The support member that protrudes from the head maintains the form by hanging, but assembling of the carport, fixing the girder to the pillar after standing the pillar, erection of the support member, erection of the beam between the girders,
The procedure of laying the main building between the beams and laying the roofing material is performed in order toward the completed state where the roof has been laid, so the assembly work is inefficient and the work of each part Is not safe and stable because it is performed at high altitudes using stepladders and supports.

[0003] Further, since the roof is fixed to the pillars via the girder, the use of a stepladder is also necessary when cleaning the roof upper surface, making cleaning difficult and dangerous, and in addition to being affected by strong winds and snowfall. Therefore, there is a possibility that the roofing material is peeled off by the negative pressure, and the entire roof is dropped due to the snowfall.

Further, as a result of the roof being supported by the eaves-side girder on the support member, the width of the roof is constant in the girder direction, so that it is impossible to cope with the presence of obstacles such as walls and trees on the site, or the entire length. The width must be reduced.

The present invention has been made in view of the actual situation of a car port suspended from above, and newly proposes a car port having a structure which solves the above-mentioned problem.

[0006]

According to the present invention, an upper chord material and a lower chord material having one end rotatably connected to each other are used, and the roof is slidably supported on pillars while rotating the roof together with both chord materials. By making it possible to switch between the state and the standing state, the workability of assembling and cleaning is improved, damage from strong winds and snowfall is avoided, and the presence of obstacles is dealt with.

The other end of the upper chord is rotatably connected to each column, and the other end of the lower chord is rotatably connected to a slider that moves up and down along the column. Together with the truss.

A purlin located at a middle portion in the width direction of the roof is rotatably connected to a joint position of the upper chord material and the lower chord material that are connected to each other, and a pillar-side end of the roof has a pillar-side end of the lower chord material. Connected to the ends or sliders, the roof is supported at two points by the upper chord and the lower chord on the elevation in the row direction.

The roof rises and lowers with respect to the pillar while rotating about the joint position between the upper chord material and the lower chord material together with the lower chord material as the slider moves up and down, and is moved into an erected state and an upright state by operating the slider. Can be switched. The roof is erected on the premises with the slider up, and stands up along the pillars with the slider down.

Since the roof can be freely switched between the erected state and the erected state, after the pillars are erected, the work of connecting the upper chord material and the lower chord material, assembling the framework of the roof, and laying the roofing material is performed on the ground. Can be performed, and the assembling workability and work efficiency are improved. Cleaning can be performed easily and carefully by being able to perform cleaning on the ground with the roof upright, and safety is ensured by not using a stepladder.

In the case of strong wind or snowfall, the vehicle stands up in the same way, thereby avoiding the influence of negative pressure and snowfall, thereby preventing the occurrence of damage. Even if snow falls on the roof, it can be easily lowered by standing up.

Japanese Utility Model Laid-Open No. 54-78238 proposes a carport that uses a link device to switch a roof between an upright state and an erected state. Stability is not ensured.

In Japanese Utility Model Laid-Open No. 2-118063-4, the roof is supported using two chords. However, since all the nodes are rigidly connected, they do not constitute a truss. Equivalent to the use of a rigid face material, it is necessary to reinforce the column or enlarge the cross section of the column because a bending moment acts on the node between the chord member and the column.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings showing one embodiment.

As shown in FIG. 1, the carport 1 of the present invention comprises a roof 3, a plurality of pillars 2, 2 located on one side thereof,
Upper chord material 4 that constitutes a truss and supports roof 3 on each pillar 2
And a lower chord material 5, and the roof 3 is supported on the pillar 2 so as to be freely switchable between an erected state and an upright state.

One end of the upper chord material 4 and one end of the lower chord material 5 are rotatably connected to each other about a horizontal axis, and the other end of the upper chord material 4 is connected to the column 2 so as to be rotatable about the horizontal axis. The other end is connected to a slider 8 that moves up and down along the column 2 so as to be rotatable around a horizontal axis. The upper chord member 4 and the lower chord member 5 constitute a truss together with the column 2, and the vertical load causes only the axial force to act on the column 2 when the roof 3 is erected because each node is a pin joint.

As shown in FIG. 2, the nodes of the upper chord member 4 and the lower chord member 5 which are connected to each other penetrate both sides, are directly connected by a pin 6 which is a horizontal axis, or are connected to a bracket protruding from each. 6 are connected by penetrating. The end of the upper chord member 4 on the column 2 side is connected to a bracket 7 fixed to the column 2, and the end of the lower chord member 5 on the column 2 side is connected to a slider 8 ascending and descending with respect to the column 2 by pins 6. You.

The roof 3 is composed of girders 31, 31 erected in the direction in which the columns 2, 2 face each other, and beams 32, erected in a direction orthogonal to this.
32 is a frame, on which an acrylic plate, a metal plate or other thin roofing material 33 is laid. Beams at both ends
A purlin 34 for maintaining the shape of the roof 3 is installed between the middle portions of the beams 32 and 32 in parallel with the girder 31.

The upper chord 4 and the lower chord 5 connected to each other
The purlin 34 of the roof 3 is connected to the upper chord 4 so as to be rotatable around the horizontal axis at the nodal position, and the end 31 of the roof 3 on the column 2 side is connected to the column 2 of the lower chord 5. The roof 3 is connected to the nodal position, and the roof 3 is supported at two points at both ends of the lower chord material 5. In the present invention, the nodes of the upper chord member 4 and the lower chord member 5 are directly connected to the purlin 34, which is a constituent material of the roof 3, so that a separate support member is added to the roof 3 as shown in Japanese Utility Model Laid-Open No. 2-118063. There is no need, and water and dust on the roofing material 33 are not blocked in the middle of the roof 3.

In the embodiment, as shown in FIG. 3, which is a partially enlarged view of FIG. 1, the purlin 34 is connected to the L-shaped bracket 9 protruding from the lower surface side of the lower chord member 5 by bolts 10. Since the roof 3 only needs to be able to follow the movement of the lower chord member 5 while rotating with respect to the upper chord member 4, a rotatable bracket is suspended from the upper chord member 4 around its horizontal axis, and a purlin 34 is connected thereto. The purlin 34 is rotatably connected to the upper chord member 4 at a node position between the upper chord member 4 and the lower chord member 5, and may be connected in any manner as long as it is supported by the upper chord member 4 or the lower chord member 5.
In addition, here, when it is necessary to move the column 2 relative to the roof 3 in the direction of the girder depending on the site or underground conditions, the nut 11 receiving the bolt 10 is attached to the purlin 34 in order to cope with the movement of the column 2. The bracket 9 is inserted into a sliding groove 341 formed in the axial direction, so that the position of the bracket 9 with respect to the purlin 34 can be adjusted.

In the embodiment, as shown in FIG.
Are connected so that the end of the lower chord 5 sandwiches the end of the lower chord 5. In this case, in particular, as shown in FIG. By contacting the lower surface of the upper chord 4 with the upper surface of the lower chord 5 while the roof 3 is erected, the lower chord 5 serves as a stopper when the roof 3 rises from the upright state.

As described above, the end of the lower chord member 5 on the column 2 side is connected to the slider 8 protruding from the column 2 with the pin 6, and the slider 8 is installed so as to be able to move up and down along the column 2. As a result, the lower chord material 5 is supported on the column 2 so as to be able to move up and down. In addition, the girder 31 on the pillar 2 side of the roof 3 is connected to the joint position with the pillar 2 of the lower chord material 5,
Although supported by the lower chord material 5 or the pillar 2, the roof 3 moves together with the lower chord material 5, so that a purlin is provided at an end of the lower chord material 5 on the pillar 2 side.
Similarly to 34, it is connected via the bracket 12 or rotatably connected to the slider 8. The end of the lower chord material 5 moves up and down along the column 2 together with the slider 8 as shown by a chain line in FIG. 1, and accordingly, the roof 3 moves together with the lower chord material 5 around the joint position between the upper chord material 4 and the lower chord material 5. Up and down with respect to the column 2 while rotating.

The slider 8 slides along a guide groove 21 formed on the surface of the pillar 2 on the roof 3 side or along a track such as a rail.
It is fixed to the column 2 by locking at a lowered position and a raised position by a lever 13 having a lock function, which is integrated therewith. In this case, if a mechanism for receiving the lock of the lever 13 is installed at an arbitrary position between the descending position and the ascending position of the slider 8, the slider 8 is stopped at an arbitrary position by the lever 13 and fixed to the column 2. Therefore, the inclination angle of the roof 3 can be adjusted as described later.

FIG. 4 shows a slider 8 connected to the lower chord member 5 of the total weight of the roof 3 for the purpose of raising and lowering the roof 3 with a small force.
In this case, the balancer 14 having a weight corresponding to the vertical load borne by the above is housed inside the column 2 and the slider 8 is connected to the pulley 15 by a wire 16 which is hung on a pulley 15. Since the roof 3 is supported at the nodes of the upper chord member 4 and the lower chord member 5 at a purlin 34 located at an intermediate portion in the width direction thereof, the load borne by the slider 8 is about half of the weight of the roof 3, The weight is just as large. In FIG. 4, reference numeral 17 denotes a handle for moving the roof 3 up and down. When manually moving the roof 3 up and down, use a balancer
Instead of 14, a spring or a damper using a restoring force can be used. When the balancer 14 is used, the load acting on the slider 8 and the weight of the balancer 14 are balanced, and the lifting and lowering of the balancer 14 does not require as much force as the weight of the roof 3.
It is also possible to operate electrically using a motor or mechanically using gears or the like.

FIG. 5 shows a state in which the roof 3 is upright. The carport 1 including the roof 3 is completely assembled in this state, and as shown in FIGS. The roof 3 is erected by raising the girder 31. The cleaning or cleaning of the roof 3 is performed in the upright state shown in FIG. 5, and the roof 3 is placed in the upright state even in a strong wind or snowfall. To prevent the roof 3 from overturning in strong winds,
Pillars will be installed on the opposite side of.

FIG. 8 shows an example of erection of the roof 3 when there is an immovable obstacle such as a wall on the eaves side of the roof 3 in the premises of the carport 1. Purlin
Since it is hung on the pillar 2 at 34, the section from the main house 34 to the eaves-side girder 31 does not affect the construction of the roof 3 because of its structure.
Since the width of the roof 3 can be reduced in that section, a collision with an obstacle is avoided by deleting a part of the roof 3.

FIG. 9 shows an example of erection of the roof 3 when trees protrude from the space between the pillars 2 and 2 toward the roof 3. The inclination angle of the roof 3 is different from that of FIG. Can be determined arbitrarily at an intermediate position between the two positions, and the end of the lower chord member 5 can be fixed at an arbitrary position by the lever 13 described above. The roof 3 can be erected.

[0028]

As described above, the present invention provides a truss that can be raised and lowered with respect to a column while rotating the roof around the joints of the upper and lower chords using the upper and lower chords constituting the truss. And the roof can be switched between the erected state and the erected state, so that the work up to the assembly and laying of the roofing material can be performed on the ground with the roof upright. Thus, workability and work efficiency can be improved, and safety can be ensured. In addition, cleaning and washing do not require the use of a stepladder, and work on the ground,
It can be done safely.

In the case of strong wind or snowfall, the effect of negative pressure and snow accumulation can also be avoided by erecting the roof, so that damage such as peeling of the roofing material and falling of the roof can be prevented. Even if snow falls on the roof, it can be easily removed by standing up.

Further, since the roof is supported by the truss at the main part of the widthwise middle part, it is possible to delete a part of the section from the main part to the eaves side girder. Since it can be fixed to the pillar at the position, even if there is an obstacle in the site, it can be dealt with without removing it.

In addition, since the truss portion composed of the upper chord material, the lower chord material and the columns supports the load on the roof and the load acting on the roof, such as wind and snow, the rigidity of the roof itself can be reduced. Therefore, the design variations of the roof can be freely increased.
