Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a systemized rafter member applied to a roof structure of a building structure, particularly a horizontal roof structure, and more specifically, to a systemized rafter member applied to a roof structure of a building structure, and more particularly, Relating to a systemized rafter member in a horizontal roof structure that is improved so that it can directly support each horizontal roof board to be engaged and can be fixed to the roof without necessarily interposing a back-up board or the like on the back side. It is something.

[Conventional technology]

In general, roof structures that are applied to normal-sized building structures and use metal materials as the main constituent materials have traditionally been broadly divided into vertical roof structures and horizontal roof structures. be.

In normal cases, each of these types is placed on a purlin material that is placed parallel to the ridge direction (hereinafter also referred to as the lateral direction) of the roof frame that makes up the surface of the roof structure to give a predetermined roof slope. A plurality of rafter members each having a single, flat roofing support surface are fixedly arranged in parallel with each other at predetermined intervals so as to be orthogonal to the building direction (hereinafter also referred to as the vertical direction). In the former vertical roof structure, vertical roof plates are used that have side edge engagement parts on both sides in the longitudinal direction and a face plate part in the center, with a base plate or the like interposed therebetween.
By arranging a plurality of these vertical roofing plates in the horizontal direction and engaging and fixing them directly or by appropriately interposing an engaging member etc. between the rafter members that are adjacent to each other in parallel, The roof is constructed by sequentially raising the roof in the vertical direction, and in the latter horizontal roof structure, a sloped surface is left in the center in the longitudinal and horizontal direction, and adjacent eaves sides that can be attached to each other are attached on both sides. Using a horizontal roofing board in which an engaging part and a line-side engaging part are formed respectively, a plurality of horizontal roofing boards are passed horizontally so as to straddle between the rafter members that are adjacent to each other in parallel. It is constructed by sequentially building up the roof in the horizontal direction by providing stepped or sawtooth-like steps in the vertical direction and engaging them with each other, and securing them with hangers as appropriate. be.

[Problem to be solved by the invention]

Therefore, each of the structures of the conventional vertical and horizontal roofs constructed as described above has advantages and disadvantages in terms of numerical application to architectural structures. They are arbitrarily selected and used based on the intended use of the architectural structure to be used, the surrounding environment, and other requirements, as well as the external appearance.

In this case, when comparing the horizontal roofing plates used in a horizontal roof structure with the vertical roofing plates of a vertical roof structure, due to its structure, each horizontal roofing plate is different from the roof surface. The coverage area range per single sheet of is relatively narrow, and therefore its effective width dimension (i.e.
Corresponding to the reduction of the roof width (7) in roof improvement, the length (corresponding to the length in the longitudinal direction) is reduced, thereby ensuring sufficient structural strength and effective wooden shelves. , a good form of external design has been obtained.

However, on the other hand, in the case of the horizontal roof structure with the above configuration, as mentioned above, the effective width of the horizontal roof panels used is narrowed to accommodate the covering surface, so even if the horizontal roof structure is Even if the number of components is the same, there is a disadvantage that the number of man-hours required for roofing per unit surface area is increased.Also, due to its structure, there is a line between the eave side engaging part and the upper and lower parts in the vertical direction. Since the side engaging portions are engaged to create a dovetail configuration, a space is inevitably formed on the back side of the face plate within the effective width range, and the corresponding face plate may be deflected due to positive pressure applied from the outside. therefore,
In order to prevent this warping, in addition to using roofing boards as the base material, back up the back side of each level of roofing. In addition to the need to insert back-up materials (wood wool cement board, urethane foam board, etc.), it also has a single, flat roofing support surface with no areas that can be used as a guideline for roofing pitch. Since a plurality of horizontal roofing boards are supported on each rafter member and only fixed by the hanger members, it is not always possible to accurately determine the raising pitch interval of each horizontal roofing board. In order to accurately set the roofing pitch interval, it is necessary to
It requires a considerable degree of skill, and as a result,
This increased the number of man-hours required during installation, including the need for separate parts, which led to an increase in costs.

This invention is an attempt to improve such conventional problems, and its purpose is to improve the horizontal roof structure when applying the horizontal roof structure to an architectural structure. By unitizing the rafter members, which serve as the foundation material for roofing roof sheets, it is possible to use multiple horizontal J1 roof sheets during construction without necessarily requiring an intervention such as a back-up board. In addition to making it possible to set the pitch interval accurately and easily, it also makes it possible to securely and easily fix it in the engaged state, improving workability and reducing costs, as well as improving structural strength and appearance. Excellent design. The object of the present invention is to provide a systemized rafter member for this type of horizontal roof structure.

(Means for Solving the Problems) In order to achieve the above-mentioned [1], the systemized rafter member in the horizontal roof structure according to the present invention has a main body of the miscellaneous wood member itself in the shape of a channel with an upwardly facing U-shape in cross section. Then, the left and right upper ends are roofed and bent into a step-like or sawtooth shape with left and right step end faces corresponding to the pitch interval left, and the left and right YfIj board receivers are attached to the bent portions. The support plate is supported, and the locking IE piece that locks the engaging part of each horizontal roof board is placed on the side wall near the end of the step, and the locking IE piece that locks the engaging part of each horizontal roof board is raised and folded.
This is the one that came in first place.

That is, the present invention provides a Japanese-style member for supporting each horizontal roof plate that is connected and engaged with an upper tier side and a lower tier side, and which includes a bottom wall portion and each left and right side wall. The cross section is shaped like an upwardly U-shaped groove, and each [i1
1. At each eave side corresponding part corresponding to the roofing pitch interval at the upper end of the wall, each left and right step end surface is made with a needle side step corresponding to the mutual engagement step of each horizontal roof board on the upper and lower side. Leave it in place and bend it inward in a stepped or serrated shape, or outward as necessary to form the left and right face plate receiving parts, and
A locking piece that locks the engaging portion of each of the horizontal roofing boards to be connected and engaged in a collapsed position is provided on at least one side wall portion close to each of the left and right stepped end faces, and is capable of freely raising and lowering. This is a systemized rafter member for a horizontal roof structure characterized by being constructed by being attached to the shaft.

[For production]

Therefore, in the present invention, the main body of the rafter member itself is shaped like a channel with an upwardly facing U-shaped cross section, and the upper ends of the left and right side walls are roofed up, leaving step end faces on the left and right corresponding to the pitch interval. The left and right side plate receiving parts are formed by bending in a step-like or sawtooth shape, and the engaging part of each horizontal roof plate is bent on at least one side wall near the left and right stepped end faces. The locking pieces that lock in the collapsed position are pivoted so that they can be raised and lowered, and the systemized rafter member is constructed in this way. A horizontal roof structure can be raised by simply connecting and engaging the plates with each other and locking the engaging portions by lowering the locking pieces. In addition, in this state of roofing, each horizontal roof board is effectively supported by each face plate support and reinforced from the back side, so external pressure can be applied without necessarily intervening a back-up board. This can eliminate the deflection of horizontal roofing boards due to this. At the same time, each of these horizontal roofing sheets is held oppositely between the predetermined roofing pitches, and the desired Jf□ condition can be maintained without any skill required. Moreover, after roofing, the inside of the rafter body and its grooves can be effectively used as rain gutters.

is formed into a predetermined shape by press forming, roll forming, a combination of these, or press forming after extrusion, as described later. Rafter members (I
Left and right locking pieces (21), (21) as hangers, which are formed in the same manner using similar materials, are pivoted to the required portions of I) so as to be able to rise and fall freely.

Further, the horizontally ruled roof structure that is raised using the rafter member (II) having the left and right locking pieces (21) and (21) is parallel to the ridge direction of the roof frame that constitutes the roof structure surface, that is, , perpendicular to the ridge direction, on each purlin material (A) arranged to give a predetermined roof slope parallel to the lateral direction,
In other words, each of the left and right locking pieces ('21) and (21
) are fixedly arranged in parallel, and on top of each of these rafter members (11) are a plurality of thin metal steel plates formed in the same manner. The roof panels (31) are directly supported and then engaged with each other from the lower eave side to the upper line side at a predetermined roofing pitch interval W, and this engaging part is connected to the left and right sides. By locking with each locking piece (21), (21), it is constructed by respectively raising the roof. In addition, at this time, the locking piece (21) is prevented from returning from the collapsed position to the original position due to the elastic force of the upper end (36) of the line-side engaging part (33) of the roof board (31). , Consideration must be given to tightening the shaft fitting strongly or caulking it.

As shown in FIG. 1, the rafter member (11) has a bottom wall (12) and left and right side walls (13) that stand up on both sides. Each of these side walls (1
:]), (1:]), on each needle side corresponding portion corresponding to the roofing pitch interval of each of the horizontally ruled roofing boards (31), (31), each of the same roofing boards ( 31), (31
) Due to the eave side step corresponding to the engagement step between each other, the left and right side plate receiving parts (15) and (15) are shaped like a step, leaving 44 steps (E) and (+4) on the left and right sides, respectively. , or they are formed by being bent inward in a serrated manner, and a continuous chamber (+6) is formed inside the groove to allow rainwater to flow down.

In addition, as for the left and right locking pieces (21), (21), as can be seen in FIG. It is located at the top of each of the side walls (+3) and (+3) that are as close as possible to one digit, and allows at least each tip end side to be lowered from the upright position to the stepped end surface (14) and (14) side. The proximal end side is attached to the shaft pin (22), (22
), and when it is in the collapsed position, the lower edge surface of the tip side is covered with the following roof plate (
The left and right locking jaws (23), which have a so-called hanger function for press-fitting and locking the line side engaging portions in (31), (
2:11) is projected and shaped, and the upper edge surface on the tip side is bent inward in the corresponding direction and coincides with the extension of the left and right face plate receiving parts (15) and (+5). The left and right presser pieces (24), (24) are shaped like

Furthermore, as shown in FIG. 2, the roof board (31) has a predetermined length in the longitudinal and lateral directions parallel to the ridge direction in the roofed state, and In the raised state, the roofing pitch is set in the transversal direction corresponding to the ridge direction at right angles, and the effective width corresponding to the stomach is left at the central face plate part (32) of the stomach, and on one side edge, Line side engagement part (33)
, the other side edge portions are formed with eave side engaging portions (34), respectively.

In this S, regarding the line side engaging portions (33) and the eave side engaging portions (34) on both sides in the transverse longitudinal direction of the roof board (31), each roof board (31), (31) is When placed adjacent to each other, they can be engaged with each other by a predetermined engagement step in the height direction, and at the time of engagement, each of the left and right locking pieces (2
Any structure may be used as long as it can be locked to the rafter member (II) by the locking jaws (23) and (23) of 1) and (21). In this case, although there is no particular limitation on the configuration for mutual engagement,
As an example of a specific engagement configuration, the former line side engagement portion (33
) includes an end folded engagement part (35) folded upward and inward for engagement, and a locking jaw part bulged upward and inward from the end folded engagement part (35). (2:]) ,
The upper end part (2:l) is restrained and locked by
36). The latter eave-side engaging portion (34) also includes a front edge hanging portion (37) that is bent downward so that the upper end portion (1B) can be enclosed therein, and this front edge hanging portion ( an end engaging edge (38) having an upwardly bulging portion (38a) on a portion thereof which is bent inward from the end portion (37) so as to be inserted into and engaged with the end folded portion (35); It is formed by

Therefore, in the structure of each member according to the first embodiment, as shown in FIGS. 3(a) and 3(b), each rafter member ( 11) are arranged and fixed at a predetermined pitch interval p, and each of the left and right locking pieces (21) and (21) are left upright, first, each rafter member is (11) Each left and right face plate support part on the lower side (+5
), (15) to connect the line side engaging portion (33) of the lower roof plate (31) to each stepped end surface (14).

(14) and then rotate each of the left and right locking pieces (21) and (21) so that they fall down, so that the line side engaging portion (33) The upper end portion (36) is the locking jaw portion (23) of the locking piece (2]), (21).

Through this work operation, the lower roof plate (31) is properly and accurately positioned on each corresponding rafter member (II) over its entire length in the lateral direction, and each of the left and right locking pieces By (21) and (21), it can be fixed and held at the same position.

Furthermore, for the roof plate (31) on the lower tier side that is fixedly held in this way, each roof plate (31) on the same tier, (
31) are connected to each other by means of connection plates (not shown) in the conventional manner, and are fixed and held one after another in exactly the same manner as described above.

In this case, if the connection for mutual connection in the longitudinal and lateral directions is to be made at the longitudinal center of the rafter member (11), even if there is water leakage from this connection, this will be prevented. It can flow out through the inside of the groove in the rafter member (11), that is, through the inter-chamber space (16). In addition, one of the reasons why each of the locking pieces (21) is arranged at the left and right positions, as in this case, is that

By repeating the same operation as described in @, the upper end (36) is further attached to the locking jaws of the left and right locking pieces (21), (21) on the upper side. The parts (23) and (2:l) are properly supported and press-fitted at the same position, and the connection is made by mutually connecting them at the same stage in the same manner as described above.

In other words, the horizontal roof structure as described above is raised 1:4, and when the roof is raised in this way, each roof plate that is connected and engaged with each of the upper and lower tiers. For both (31) and (31), the respective central face plate parts (32) and (32) are supported by the left and right face plate support parts (15) and (+5) of each rafter member (11). , since it is reinforced and supported from the back side, it is possible to effectively eliminate the deflection of the center panel part (32) due to external pressure, and in this case, each roof panel part (31
) without any skill, at a predetermined roofing pitch every week, and without using any kind of hangers made of separate parts, by locking and holding the roofing securely. You get it.

In addition, in the configuration of the first embodiment, a piece (21) is provided on each even 1.

〔Effect of the invention〕

As described in detail above, according to the present invention, in the rafter member for supporting each horizontally ruled roof plate connected and engaged with the first tier side and the lower tier side, the bottom wall portion and It has left and right side walls and is shaped like a groove in cross section or upwards in the shape of a U-shape.
At the corresponding part of each eave side corresponding to the pitch of roofing at the upper end of each side wall, and on the left and right at the eave side step corresponding to the engagement step between each horizontally ruled roof board on the upper and lower side. Leaving each stepped end surface, bend it inward in a step-like or serrated shape, or if necessary, bend it outward at the tail to form the left and right face plate receiving parts, and also place it close to the left and right stepped end surfaces. In addition, a locking piece that locks the engaging portion of each horizontally ruled roof board that is connected and engaged between adjacent sides in the collapsed position is rotatably mounted on at least one side wall portion, and in this way, Since a systemized rafter member is constructed, the horizontally ruled roof plates on the lower and upper sides are connected and engaged with each other based on the end face of each step, and the engaging portion is used to prevent the locking piece from collapsing. With an extremely simple work operation of just locking the horizontally ruled roof panels, each of these horizontally ruled roof panels is supported on each face plate support part, and the locking pieces are used to lock the horizontally ruled roof panels to create the desired horizontally ruled roof. Due to its structure, it can be roofed easily and with good workability. When each horizontal roofing board is raised in this way, each horizontal roofing board is effectively supported by each face plate support section, and is sufficiently reinforced and supported from the back side. Therefore, in this case, it is possible to satisfactorily eliminate the deflection of horizontal roofing boards due to external pressure without necessarily interposing a back-up board or the like.

Furthermore, each of these horizontal roofing sheets can be accurately maintained between the predetermined roofing pitches, so that the desired shape can be maintained without any skill required. Also,
By making connections between the horizontal roof plates of the same level and each level at the center of the rafter members in the longitudinal direction, the inside of the structure with these rafter members can be effectively used as a rain gutter. . Moreover, it has excellent features in that it is structurally simple, easy to provide, and can be provided at low cost.
