Description

  The present invention relates to a mounting structure for panel members such as a PC panel (precast concrete panel) and an ALC panel provided substantially perpendicularly to a building frame.

  In order to attach panel members such as a PC panel and an ALC panel to a building frame, examples of conventional mounting structures include those shown in FIGS.

The mounting structure 50 in FIG. 6 (a) has a weld metal 52 embedded in the lower surface of the casing 51, a notch 54 formed in the vicinity of the upper end of the wall panel 53, and a weld metal 55 previously embedded therein. The weld metal members 52 and 55 of the members are joined together by welding, and the notch portion of the wall panel 53 is filled with a resin mortar 56 or the like.
However, when welding the metal fittings 52 and 55, the work must be performed upward, so that workability is poor, and the quality of the joint is greatly affected by the welding technique of the operator. In addition, the welding operation is easily influenced by the weather, and process management is difficult. Furthermore, the resin mortar provided in the notch also has a problem that cracks and skin cracks are likely to occur due to aging.

Next, in the mounting structure 60 in FIG. 6B, a metal fitting 62 with an insert or a box incorporating a nut (not shown) is embedded in the lower surface of the casing 61, and a metal fitting 64 with a bolt is embedded near the upper end of the wall panel 63. The wall panel 63 is attached to the lower surface of the housing 61 by attaching the angle fastener 65 to both the hardwares 62 and 64.
However, in such a mounting structure 60, the angle fastener 65 appears on the surface, which causes an aesthetic problem.

6C, a box metal 72 is embedded in the lower surface of a precast concrete structure housing 71, a sheath tube 74 is embedded in the vicinity of the upper end of the wall panel 73, and the housing 71 is placed on the upper surface of the wall panel 73. At the time of installation, the pin bolt 75 is attached to the box metal 72 and inserted into the sheath tube 74, and the grout material 76 is injected into the sheath tube 74 to fix the pin bolt 75, whereby the wall panel 73 is attached to the lower surface of the housing 71. It is attached.
However, in such an attachment structure 70, the wall panel 73 is attached in advance, requires temporary fixing with temporary support or the like, and requires temporary support until the strength of the grout material 76 is generated. Further, the insertion state of the structurally important pin bolt 75 cannot be visually confirmed. In addition, it is difficult to apply the case when the frame 71 is formed by a conventional method such as cast-in-place concrete instead of precast concrete.

Further, in the mounting structure 80 shown in FIG. 6D, a weld metal 82 is embedded in advance on the lower surface of the casing 81, and an angle piece 83 is welded to the weld metal 82 at a construction site. Is embedded, and a plate member 86 (inazuma plate) bent as shown in the figure is fixed, and an angle piece 83 is engaged with a gap between the inazuma plate 86 and the surface of the wall panel 84, so that the wall panel 84 is a casing. 81 is attached to the lower surface.
However, even in this mounting structure 80, when the angle piece 83 is fixed to the weld metal 82, the welding work must be performed upward, and the same problem as the mounting structure 50 in FIG. 6A occurs. .

In addition, if prior arts other than FIGS. 6A to 6D are given, Patent Document 1 describes a curtain wall mounting structure in which interlayer displacement of a building structure is absorbed by a loose hole. Patent Document 2 describes a structure for attaching a PC plate to a reinforced concrete structure in which a fastener is embedded in a PC panel and a fixing bracket for receiving the PC fastener and fixing the PC plate to the frame side is embedded in the frame concrete. Yes.
However, the inventions described in Patent Document 1 and Patent Document 2 do not sufficiently solve the above-described problems.
Japanese Patent Laid-Open No. 10-169054 JP 2000-328701 A

  In view of the current situation as described above, the problem of the present invention is that it does not require welding work at the construction site, can be attached only by mechanical connection, and can proceed with process management without being affected by the weather. Another object of the present invention is to provide a panel member mounting structure that can be obtained and can obtain stable quality without being affected by the construction technique of the operator.

  In order to solve the above-described problems, the present invention provides a panel member mounting structure in which a panel member is mounted on a lower surface of a casing substantially vertically by a fastener including a rod body, a T-shaped connecting member, and a fixing tool. Is provided with a horizontally long loose hole, and a receiving member capable of fixing one end of the rod body is embedded in the side surface near the upper end of the panel member. The T-shaped connecting member is connected to a horizontally long loose hole on the bottom surface of the casing. The rod body is inserted into the annular portion and fixed by the fixing tool. The tip of the rod body is fixed to the panel member by the receiving member, and the influence on the panel member due to the interlayer displacement of the casing is controlled by the loop on the bottom surface of the casing. Mounting structure of the is panel member that so as to absorb holes are provided.

  According to the present invention, there is also provided a panel member mounting structure in which the panel member is mounted on the lower surface of the casing substantially vertically by a fastener including a rod body, a T-shaped connecting member, and a fixing tool. A receiving member that can be fixed to the panel member, a laterally long loose hole is provided on the side surface near the upper end of the panel member, and the T-shaped connecting member has a T-shaped projecting portion that extends to both sides at one end of the housing. An annular portion constituting a loose hole is provided at the other end of the housing, and the T-shaped connecting member is engaged with a horizontally long loose hole of the panel member, and a rod is attached to the annular portion. The body is inserted and fixed by the fixing tool, the tip of the rod body is fixed to the lower surface of the housing by the receiving member, and the influence of the displacement between the housing members on the panel member is absorbed by the loose hole of the panel member. Mounting structure of the is panel member that was is provided.

In the present invention, as the rod body, a screw bolt in which screw threads are formed at least at predetermined positions of the front end and the rear end can be used, and the receiving member includes a female screw member capable of screwing the screw bolt. A rod body inserted through the annular portion of the T-shaped connecting member can be fixed by a fixing tool including a washer and a nut.
By configuring the rod body, the receiving member, and the fixing tool in this manner, the rod body and the annular portion of the T-shaped coupling member can be more easily coupled.

In the mounting structure of the present invention, the T-shaped connecting member has a T-shaped projecting portion and an annular portion, the T-shaped projecting portion is engaged with the loose hole of the housing or the panel member, and the rod body is inserted into the annular portion. Since the panel member is attached to the casing by fixing the tip of the rod body to the panel member or the casing, all the machines do not require welding work at the construction site. It is possible to form the mounting structure only by the effective engagement and connection.
Therefore, process control can be advanced without being affected by the weather, and stable quality can be obtained without being affected by the operator's construction technique.
Furthermore, the influence of the panel interlayer displacement on the in-plane direction of the panel member can be absorbed by the engagement portion between the loose hole of the heel and the T-shaped connecting member. This can be easily performed at the insertion point of the rod body into the annular portion (loose hole) of the shape connecting member, whereby the mounting structure of the present invention has good workability.
