Description

  The present invention relates to a folded-plate roof receiver that can cope well with thermal expansion and contraction in the longitudinal direction of a roof-plate material having a long longitudinal direction in the flow direction of the folded-plate roof.

  2. Description of the Related Art Conventionally, various roofing materials have been developed that cope with thermal expansion and contraction even when thermal expansion and contraction occurs in the longitudinal direction of the roof plate material having a long longitudinal direction in the flow direction of the folded roof. In the folded plate roof, in the folded plate roof in which the mountain portion and the valley portion are continuous, when the longitudinal direction of the roof plate material is long due to a change in the outside air temperature, the roof plate material expands and contracts along the longitudinal direction.

  This amount of expansion and contraction is extremely large at high temperatures such as in summer, and thermal distortion occurs, so that large distortions due to thermal expansion and contraction appear especially at the connection parts of the connecting parts such as the buttocks, and the squeak noise. In order to eliminate this phenomenon, a movable roof support (also called a slide-type fixing bracket) that can be moved appropriately in response to thermal expansion and contraction has been developed. This is disclosed in Patent Document 1 and Patent Document 2.

  Since the movable roof supporter absorbs the temperature conditions at the time of construction and the displacement on the expansion side and the contraction side in the use state after completion, it is necessary to ensure a sliding margin. However, even when the movable roof support is attached with the suspension set at the center position of the slide (centering) at the time of construction, if the roofing work is performed thereafter, the suspension of the movable roof support will be released at that stage. It often happens that it slides on its own and is fixed to the roofing board at an inappropriate position (there is no allowance for expansion / contraction absorption).

  In this case, the thermal expansion / contraction force is concentrated on the movable roof receiver having no expansion / contraction allowance, and the movable roof receiver may be damaged. Even when a conventional movable roof support is used for a roof constructed by a roof plate material of a folded plate roof, particularly in a large building, the sliding performance may not be sufficiently exhibited. In addition, a load due to excessive thermal expansion and contraction of the roof plate material acts on the fixed roof support (also referred to as a restraint-type fixing bracket), and the fixed roof support may be damaged.

  The following factors can be considered for such damage. In addition to the thermal expansion and contraction force, the folded plate roof plate material is subjected to various loads such as the weight of the roof plate material itself, a snow load, a wind load, and an earthquake load. When these loads are applied, it may not slide smoothly. In addition, it is conceivable that the slide performance deteriorates due to these loads during the in-service period of the building. In general, movable roof supports that can cope with thermal expansion and contraction are disclosed in Patent Document 1 and Patent Document 2, but in these Patent Documents 1 and 2, the above-mentioned problems or slides are performed during construction. The inconvenient point that the hanger is displaced from the center position has not been solved.

  In general, a fixed roof support used for a double roof has a larger load due to thermal expansion and contraction. This is because in buildings that use double roofs, it is common to provide air conditioning, etc., and as a result, there is little variation in the temperature conditions of the roof and the roofing board material for lowering the double roof, and the roof for upper roofing. The temperature change of the plate material is directly applied to the heat insulator as a heat expansion / contraction load. In addition, because there is a heat insulating material under the upper roofing board material, it becomes difficult for heat to escape under the upper roofing board material, so the temperature fluctuation of the upper roofing board material becomes larger, and there is a demand for the development of a movable roof receiver. There is.

  In the case of thermal expansion and contraction of a metal folded-plate roof, the length of, for example, the position of 50m at the tip and the amount of expansion / contraction are different 20m inside from the location, and the spring constant corresponding to the amount of expansion / contraction In reality, it is difficult to change this. Therefore, it is desired that the same force acts at any position. It has been found that a roller-mite spring exists as a principle mechanism that plays the role, but how to apply it is an important issue.

  The problem to be solved by the present invention (technical problem or purpose) is that the longitudinal direction of the roof plate material as the flow direction of the folded plate roof is long, even if thermal expansion and contraction occurs in the longitudinal direction, It is possible to follow well, and in particular, to develop the same force at any position regardless of the amount of expansion and contraction, and to realize resistance by that force .

In the case of a plate roof, the roof surface fixing portion 7 serves as a fitting suspension.

  The casing A is composed of a first divided casing 1 and a second divided casing 2, and sandwiches a flange 81 in the roof plate material 8 of the folded roof R by the lower groove-shaped portions 12f and 22f. It is configured. In the case of a single layer, the first divided casing 1 and the second divided casing 2 may be integrally formed without being divided. At that time, the groove portions 12f and 22f are not formed.

  The first divided casing 1 and the second divided casing 2 are composed of outer surface side members 11 and 21 and inner surface side members 12 and 22. The outer surface side member 11 has a hanging surface portion 11b formed from one end of the upper surface portion 11a, mounting portions 11c and 11c are provided on the same plane at the front and rear ends of the hanging surface portion 11b, and the hanging surface portion on the lower side. A front part 11d and a rear part 11e are formed by bending about 90 degrees from the front and rear ends of 11b.

  Further, a bottom surface portion 11f is bent from the lower end of the drooping surface portion 11b toward the upper surface portion 11a. Further, the outer surface side member 21 is also formed with an upper surface portion 21a, a hanging surface portion 21b, attachment portions 21c and 21c, a front surface portion 21d, a rear surface 21e, and a bottom surface portion 11f.

  Further, the inner surface side member 12 is formed with a drooping lower surface portion 12b from one end of the upper surface portion 12a, and is bent about 90 degrees from the front and rear ends of the drooping lower surface portion 12b to form a front surface portion 12c and a rear surface 12d. Mounting portions 12e and 12e are provided so as to be bent from the ends of the front surface portion 12c and the rear surface surface 12d so as to be flush with the drooping surface portion 12b.

  Further, a bottom surface portion 12g that bends from the lower end of the drooping bottom surface portion 12b toward the top surface portion 12a is formed to be bent. Further, the inner surface side member 22 is also formed with an upper surface portion 22a, a hanging surface portion 22b, a front surface portion 22c, a rear surface 22d, mounting portions 22e and 22e, a groove portion 22f, and a bottom surface portion 22g.

  The outer surface side member 11 and the inner surface side member 12 of the first divided casing 1 are superposed on the mounting portions 11c and 12e, and a box-shaped portion is formed by the upper surface, the drooping surface, and the front and rear surfaces. The comb tooth body 3 is accommodated. The resin comb tooth body 3 includes an upper bar-shaped mounting portion 31 and unit comb teeth 32, 32,... Facing in the direction perpendicular to the longitudinal direction along the longitudinal direction of the bar-shaped mounting portion 31. .. and a gap 33 between adjacent unit comb teeth 32, 32, and the material is made of a hard synthetic resin.

  The bar-shaped attachment portion 31 is fixed to the upper surface portions 11a, 12a of the first divided casing 1 with screws or the like. Horizontal elongated holes 13, 13 formed as elongated holes in the lateral direction are formed in the hanging surfaces 11 b, 12 b of the first divided casing 1 that are fixed. Further, the upper surface portions 21a and 22a of the second divided casing 2 are also fixed by screws or the like, and the vertically long holes 23 and 23 are formed on the respective hanging surfaces 21b and 22b.

  The horizontally long holes 13 and 13 and the horizontally long holes 23 and 23 are formed to have the same size (including substantially the same). The horizontal shaft portion 4 is provided so as to penetrate the horizontal elongated holes 13, 13 and 23, 23. In particular, when the horizontal shaft part 4 slides in the longitudinal direction through the horizontally long holes 13, 13 and 23, 23, the lower ends of the unit comb teeth 32, 32,. Are set so as to press the horizontal shaft portions 4, 4 downward at the lower ends of the unit comb teeth 32, 32,.

  In a specific configuration, concave groove portions 32a and 32a are formed only at the lower ends of the unit comb teeth 32 and 32 at corresponding positions so that the two horizontal shaft portions 4 and 4 can be pushed downward. Other than the unit comb teeth 32, 32, sharp edges 32 b, 32 b,. In the embodiment, the two horizontal shaft portions 4 and 4 are provided for the purpose of stability, but there may be only one. Moreover,

  Next, the operation of the present invention will be described with reference to FIG. In FIG. 4A, although it is a neutral position, the horizontal axis | shaft part 4 moves rightward in this paper surface. Actually, it is thermally expanded by the action of the thermal expansion and contraction action and moves through the guide member 5. And it becomes like (B) and the lower end side of the adjacent unit comb tooth 32 is bent.

  In this case, the horizontal shaft portion 4 is applied with a force of F in the right direction, and the resistance force R is obtained by the bending force while bending the two adjacent unit comb teeth 32. Furthermore, when the horizontal shaft portion 4 slides to the right side, as shown in FIG. 4C, particularly, only one unit comb tooth 32 is bent.

Furthermore, if it slides to the right side, as shown to (D), the unit comb tooth 32 will bend more angles. The resistance force R at this time becomes large. Then, when sliding to the right side, the unit comb teeth 32 are bent at a maximum of more angles as shown in (E). At this time, the resistance force R is maximized.
After that, the unit comb teeth 32 that have been bent so far return to a straight state (see FIG. 4F).

  The state where such a resistance force is generated is a saw blade state as shown in FIG. That is, when the state where one unit comb 32 is bent further increases, it increases in a directly proportional state. However, when the unit comb 32 is detached from one unit comb 32, the resistance force decreases in the drooping state. When the unit comb teeth 32 are bent, the resistance force increases again, and then comes off, and these are repeated to form a saw blade state.

  Further, as shown in FIG. 8, the horizontal axis 4 is a wide plate portion with respect to a plurality of unit comb teeth 32, 32,. As the horizontal shaft portion 4 slides to the right side, the three unit comb teeth 32, 32, 32 may be pressed, or there may be only two, resulting in the graph state shown in FIG. Although the saw blade is up and down, it can be provided as a constant load repulsion spring with a very simple configuration.

  First, at the time of construction, when the roof plate material 8 of the folded-plate roof R is attached via the folded-plate roof receiver of the present invention, the hanger 71 of the roof surface fixing portion 7 is located at a substantially central position of the casing A. It is set to be in the neutral position. Specifically, the centering of the suspension 71 can always be maintained even immediately after the roof construction.

  The structure shown in FIG. 8 (A) is a configuration in which the folded plate roof receiving device of the first embodiment is used for the roof plate material 8 of the two-layer folded plate roof R. Moreover, what was shown to FIG. 8 (B) is the structure which used the folded-plate roof holder of 2nd Embodiment for the roof-plate material 8 of the single-layer folded-plate roof R. FIG. The embodiment of the present invention can be used as a constant load, non-repulsive spring with a particularly simple configuration.
