Description

  The present invention relates to a lower end structure of a wall used for a base part of an outer wall material of a building or structure requiring fireproof performance and fireproof performance.

  In general, a panel in which a core material made of a synthetic resin foam is sandwiched between a thin plate-like surface material and a back material, and an end surface wall is formed at an end portion has been invented and devised on the market. (For example, refer to Patent Documents 1 and 2).

JP-A-9-195411 JP 7-003995 A

  However, when the panels of Patent Documents 1 and 2 are installed vertically, the inter-layer deformation angle of the frame is 1/200 or less by the specified value, but there are appropriate measures for book walls, interior / exterior materials, equipment, etc. Only when it is taken, relaxation is recognized to an interlayer deformation angle of 1/120 or less. Therefore, in order to prevent the panel itself from being damaged due to the interlayer deformation of the panel, when the working width is 900 mm at the lower end of the panel, the clearance height from the drainer = working width 900/120 = 7.5 mm, the working width is In the case of 600 mm, it was necessary to form a gap with a gap height with a drainer = working width 600/120 = 5 mm. However, in general construction, as shown in FIGS. 13 to 16, an L-shaped angle starter C is generally used, and this starter C is mounted on the drainer B attached to the base. In addition, when the building rolls due to an earthquake or the like and the panel A is displaced and the panel A is displaced, only one of the long sides of the panel A is fixed to the housing as shown in FIG. Since the panel A is displaced following the interlayer deformation of the casing α because it is not fixed to the casing, and the drainage B and the starter C are stronger than the panel A, the end A1 of the panel A is shown in FIG. As shown in FIG. 2, the material was pressed against the starter C and was damaged or deformed.

  In order to solve such drawbacks, the present invention is formed from a fixed surface having at least a vertical flat surface used when a panel is vertically stretched, and a mounting surface in which the upper end of the fixed surface protrudes to the outdoor side. The long starter is formed of a substantially vertical flat fixed surface, an inclined surface that protrudes by inclining the lower end of the fixed surface of the fixed surface to the outdoor side, and a decorative surface that hangs down the tip of the inclined surface. A bottom end structure of a wall, which is placed on a drainer via an elastic member, and the vicinity of the center of the working width of the panel is fixed with a fixture. Is to provide.

  According to the lower end structure of the wall according to the present invention, (1) since the elastic member is formed between the starter and the drainer, the drainer does not deform with respect to the deformation of the starter. (2) The panel can be prevented from being damaged when the frame is displaced by lateral vibration such as an earthquake. (3) Since the panel can follow the roll of an earthquake without breakage, the panel does not peel off from the frame. (4) Since the panel can follow the roll of an earthquake without breakage, the panel itself functions as a reinforcing material that prevents the frame from collapsing. (5) Since there is no damage to the panel during an earthquake, the panel will not be peeled off from the housing. (6) There is no danger to humans due to panel peeling. There are features and effects.

  Further, the elastic member C4 is made of a series of elastic materials, ie, elastic rubber, whose main component is an organic polymer such as natural rubber or synthetic rubber (polybutadiene, nitrile, or chloroprene).

  Then, the construction example of the lower end part structure of the wall which concerns on this invention is demonstrated. First, as shown in FIG. 1, a long drainage B as shown in FIG. 8 is fixed continuously to the base portion of the housing α via a fixture β.

  When the construction of draining B is completed, a long starter C as shown in FIG. 9 is continuously fixed on the housing α via the fixture β on the fixing surface lower end B4 of the draining B.

  In this case, when the starter C is fixed, the working width of the panel A is W as shown in FIG. That is, as shown in FIG. 2, the fixing position of the fixing tool β is to fix the vicinity of the approximate center of the working width W, and is formed at a position of 2 / W that is the center of the working width W in the drawing. In other words, the placement position of the fixture β is the pitch acting width W and the placement position is the center of the working width W of the panel A. Of course, in order to fix the starter C with the pitch of the working width W, when the width of the working width W is widened and the load on the panel A is increased, the two fixtures β in the vicinity of the left and right of the position of W / 2. If the working width W is reduced and the load on the panel A is reduced, the fixed pitch is set to 2W at the position W / 2. It can also be formed to 3 W or the like.

  In addition, the specified value of the interlayer deformation angle is 1/200 or less, but the interlayer deformation angle can be relaxed to 1/120 or less only when appropriate measures are taken for book walls, interior / exterior materials, equipment, etc. It recognized. For this reason, when the working width W is 900 mm, the height of the elastic member C4 is the height h of the elastic member C4 = working width 900/120 = 7.5 mm (+ the deformation limit thickness of the elastic member C4), and the working width. When W is 600 mm, the height h of the elastic member C4 = working width 600/120 = 5 mm (+ the deformation limit thickness of the elastic member C4). Of course, the height dimension of the elastic member C4 may be larger than this value.

  When the wall displacement shown in FIG. 2 is subjected to an inter-layer displacement follow-up performance test on the panel A as shown in FIG. 3, the panel A is displaced about the fixture β. Will do. The starter C is deformed in response to this displacement, but the starter C can be deformed along with the displacement of the panel A by the elastic member C4 formed between the starter C and the drainer B. The end A1 of A will not be deformed.

  When the installation of the starter C is completed, the panel A as shown in FIG. 4 is placed on the mounting surface C2 of the starter C as shown in FIG. The joining piece 32 is inserted into the female engaging groove 33, and the fixing groove 15 of the female connecting portion 5 at the other end is driven and fixed to the housing α by the fixing device β at a constant pitch. By repeating such a process, the panel A is completed by vertical stretching as shown in FIGS. 1 and 2.
