Description

  The present invention relates to a member for forming a through hole in a wall.

  Conventionally, in order to pass pipes through a frame, first, a through hole is formed in the frame, and the pipes are inserted through the formed through hole. After the sheet-like heat-expanding heat-resistant seal material is wound around the portion of the pipes that have passed through the through-holes, the wound state is held by an adhesive tape provided outside the heat-expansion heat-resistant seal material. From this state, the piping is moved so that the heat-expandable heat-resistant seal material is located in the through hole. After that, a refractory filler such as mortar or refractory putty is filled between the outer peripheral surface of the outer pressure-sensitive adhesive tape to which the moved heat-expandable heat-resistant sealing material is attached and the inner peripheral surface of the through hole (for example, Patent Document 1). ).

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The member for forming a through hole in a wall according to the present invention will be described. The through-hole forming member includes an upper member located on the upper side and a lower member located on the lower side of the same configuration as the upper member, but may have a different configuration. 1 to 8 show one lower member 1, and by rotating the lower member 1 by 180 degrees around the longitudinal axis, the upper member 2 (see FIGS. 10A and 10B). ) Can be configured. Here, the lower member 1 and the upper member 2 are configured from the same member, so that the lower member 1 and the upper member 2 can be fixed without worrying about the vertical direction, but may be configured from different shapes. . The lower member 1 includes a bottom wall portion 3 and left and right side wall portions 4A and 4B extending upward from both ends in the width direction of the bottom wall portion 3. Here, the upper member 2 and the lower member 1 are formed of a synthetic resin, but may be made of metal or the like, and the material is not limited.

  The bottom wall portion 3 has a flat bottom surface, and is provided with a tapered portion 5 having a diameter that increases toward the outside at both ends in the longitudinal direction. The bottom wall 3 has a substantially rectangular accommodation space (in FIG. 2, a substantially rectangular shape that is long in the width direction in plan view) that accommodates the refractory material 6 shown in FIG. A concave portion 7 to be formed is formed, and a plurality (five in the figure) of reinforcing ribs 9 that support the pipes 8 from both ends in the longitudinal direction of the concave portion 7 toward the tapered portions 5 and 5 are formed. . As shown in FIG. 2, the ribs 9 are formed along the longitudinal direction (axial direction of the cylindrical shape), and are located on the outside in the width direction so as to reliably support the pipes 8 having a circular cross section. The height is increased by about 9 (see FIGS. 7 and 8). The lower member 1 is attached to the floor (or ceiling) F at the longitudinal center ends of the ribs 9 located at the center in the width direction of the ten ribs 9 located on both sides of the recess 7. 9 (see FIG. 9 (a)) for fixing screws (fastening members) 10 are provided. If the plurality of ribs 9 are formed along the axial direction of the cylindrical shape, the ribs 9 will be formed along the direction in which the pipes 8 are inserted. 8 can be reduced. Examples of the pipes 8 include a hot water supply pipe, a water supply pipe, a drain pipe, and a conduit pipe. Here, the screw 10 is shown as a fastening member, but it is a pin that is inserted into a hole provided in the floor or ceiling and is a band that fastens and fixes the through-hole forming member H to a fixing portion attached to the floor or ceiling. Is also good.

  As the refractory material 6, a thermally expandable refractory material is used. The heat-expandable refractory material is a member having heat expansion properties (the property of increasing the volume by heating) and fire resistance (the property of easily withstanding heat, the property of a high melting temperature and the difficulty of burning). As the heat-expandable refractory material, a known material can be used without any particular limitation. For example, a putty-like member (heat-expandable putty-like refractory material) can be used. For example, when heated to a predetermined temperature (for example, 200 ° C.) or more, the heat-expandable refractory material expands in its thickness direction and expands in the piping 8 and the through-hole 19 of the through-hole forming member H (FIG. 10B). (See FIG. 1) to prevent the flame from moving through the through-hole forming member H from one room to the other room across the wall.

  Describing the left and right side walls 4A and 4B, as shown in FIGS. 2 and 7, one (left) side wall 4A is higher than the other (right) side wall 4B. In addition, an enclosure having three surfaces on the inner surface of the right side wall portion 4B such that a rectangular space 12 which is long in the longitudinal direction and which is rectangular in a plan view is formed at each of both end portions in the longitudinal direction of the right side wall portion 4B which is raised. A section 13 is provided. On the other hand, each of the lower end portions of the left side wall portion 4 </ b> A is provided with a rectangular plate portion 14 in a plan view that can enter the space 12 at each of both ends in the longitudinal direction.
