[0004]

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes an assembling type car port, and the car port 1 is provided between a pair of right and left support members 2 each having a lower end buried in a garage floor surface, and is installed between the pair of right and left support members 2 respectively. Spar members 3, a plurality of rafter members 4 erected in parallel between the spar members 3, a ridge member 5 erected between the tops of the rafter members 4, and a plurality of ridge members erected between the rafter members 4 in parallel It is formed by using an aluminum profile such as the purlin member 6 and an acrylic resin roof plate 7 laid on the upper surface of the purlin member 6, and these basic configurations are all conventional. .

[0005] The rafter member 4 is formed by bending an aluminum member having a substantially rectangular cross section into a mountain shape so that the center is the top, and both right and left ends thereof are screwed to the beam member 3. On the other hand, the edge of the roof plate 7 is fixed to the upper end surface by using the rafter cover 8, and further, the both sides of the rafter member 4, which is the attachment portion of the purlin member 6, have a substantially L-shaped cross section. A bent piece 4a and a projecting piece 4b projecting from a position above the base end of the bent piece 4a are integrally formed in the longitudinal direction, and the inner peripheral surface of the bent piece 4a and the rafter member 4 are formed. The groove 4c formed by the side surface functions as a dew-receiving groove for receiving the dew attached to the rafter member 4 and the roof plate 7 so as to prevent the dew from dropping into the garage as it is.

On the other hand, the purlin member 6 is formed so as to integrally have an upper half portion having a substantially T-shaped cross section and a lower half portion having a substantially inverted U-shaped cross section. Roof board 7
An elastic sheet 9 for abutting and supporting the pair is attached to the lower end of a pair of leg pieces 6a formed in the lower half, and a stopper piece 6b that is bent in an inwardly bent shape, and a triangular shape. A protruding locking claw 6c is formed.

Further, a notch 6d is formed at an end of the both leg pieces 6a. The notch 6d is formed in a vertical piece 4d of a bent piece 4a formed in the rafter member 4. The notch 6d can be fitted to the vertical piece 4a of the bent piece 4a.
When fitted to d, the purlin member 6 is connected to the rafter member 4 in a state where movement in the front-rear direction (longitudinal direction of the purlin member 6) is restricted.

Further, reference numeral 4e denotes a projecting piece 4b of the rafter member 4.
The notch 4e is formed with a pair of notches 4e formed with a pair of notches 4e of the purlin member 6 so that the two leg pieces 6a can be fitted together. The notch width is set so that the locking claw 6c of the two leg pieces 6a can be stopped and locked, and the two leg pieces 6a are notched 4e.
Rafters are passed over from the top
Notch 6 formed in vertical piece 4d on four sides and leg piece 6a on purlin side
d is fitted in the left and right direction (of the rafter member 4).
While displacement in the longitudinal direction) and in the front-rear direction is regulated
And further provided on the projecting piece 4b formed on the rafter projecting piece 4b.
The notch 4e formed on the leg 4a is
From the side to the lower side, and the locking claw 6c is
The lower part of the purlin 6
The movement is regulated. In other words, purlin 6 is in front
With the simple fitting operation, it is left and right with respect to the rafter 4
The rafter member 4 can be assembled to the rafter member 4 in such a manner that the movement is restricted in all directions, that is, before and after, right and left, and up and down.

The pitch of the notch 4e is set slightly smaller than the pitch of the leg 6a. That is, the two leg portions 6a are elastically deformed and the notch portions 4e are formed.
In this state, the so-called spring back is used to elastically contact the notch 4e to restrict rattling of the purlin member 6.

In the embodiment of the present invention constructed as described above, when the purlin member 6 is erected between the rafter members 4, the two leg pieces 6a of the purlin member 6 are connected to the rafter member 4 side as shown in FIG. If the purlin member 6 is fitted into the notch 4e, the purlin member 6 can be easily assembled to the rafter member 4 in a so-called pattin type without using a tool or the like. And in this case, the purlin member 6
The movement in the front-rear direction is restricted based on the fitting of the notch 6d into the bent piece 4a, and the front-back and left-right directions are controlled based on the fitting of the two legs 4a into the notch 6e. The movement is restricted, and furthermore, the vertical movement is restricted based on the locking claw 4c of the leg piece 4a being retained and locked from below by the notch 6e, and is firmly fixed to the rafter member 4. Will be. Therefore, unlike the conventional case where the purlin member 6 is screwed to the rafter member 4, the troublesome and time-consuming screwing operation is not performed for each fixing point, and the purlin member 6 can be extremely easily formed by a so-called one-touch patch type. Can be assembled. As a result, assembling type carport 1
It is possible to dramatically improve the assembly workability, or it is possible to reduce the number of components such as screws and to effectively reduce the cost.

Further, the fixing structure of the present embodiment utilizes the existing bent piece 4a formed for receiving dew condensation as it is, and replaces the conventional screw hole with the notched portions 4e, 6e.
Since it can be implemented by forming d, the number of steps and the structure are not complicated.

Furthermore, in the embodiment, since the backlash is removed by using the spring back of the leg piece 6a, the purlin member 6 can be attached extremely firmly without rattling without using screws.

[0013]

In summary, since the present invention is constructed as described above, the purlin member is fixedly mounted in a bridge-like manner between a plurality of juxtaposed rafter members while the purlin member is screwed. Without using a piece, cut both leg pieces
If the notch is fitted so that it passes
The vertical piece on the rafter side and the notch formed on the purlin side leg piece
To be fitted, the left and right direction (the longitudinal direction of the rafters
Direction) and forward / backward displacement are restricted.
In addition, the notch formed on the rafter protruding piece, the locking formed on the leg piece
The claws pass from the top to the bottom, and the locking claws
Locking from below causes the main house to shift vertically.
Movement will be regulated. As a result, the main building is
Vertical and vertical displacements are restricted
In this state, it is firmly attached to the rafter member. Therefore, it is possible to assemble the purlin member very easily, which does not need to perform a troublesome and time-consuming screwing operation for each fixing point as in the conventional case, and as a result, an assembled roof constituting an assembling type car port or the like can be obtained. It is possible to dramatically improve the assembling workability, or to reduce the cost effectively due to the decrease in the number of parts.
