[55] The support member 300 for fixing the concrete panel jointing member 100 on the wall of the structure is engaged with the support member engagement portion 120 of the jointing member main body 110 while it is fixed on the wall 10 of the structure to support the concrete panel 200.
[56] Accordingly, it is possible to build up concrete panels and form a mechanism for fixing the panels on the wall by mounting the concrete panel jointing member 100 such that the lower panel insertion protrusion 130 is inserted into the upper jointing groove 210 of the lower concrete panel 200b after the lower concrete panel 200b is mounted, and then, the upper panel insertion protrusion 140 of the concrete panel jointing member 100 is inserted into the lower jointing groove of the upper concrete panel 220a.
[57] In this manner, the precast high quality concrete panels 200 can be conveniently and safely mounted on the wall 10 of the structure.
[58] Hereinafter, the concrete panel jointing member 100 according to an embodiment of the present invention will be described in more detail.
[59] Preferably, the jointing member main body 110, the lower panel insertion protrusion
130, and the upper panel insertion protrusion 140 has a thickness as thin as possible within an allowable strength limitation because it may provide a shallower gap between the concrete panels 200 and thus provide a safer structure.
[60] The lower panel insertion protrusion 130 and the upper panel insertion protrusion
140 may be provided as a separate member engaged with the jointing member main body 110. However, it is preferable that they are integrated with the jointing member main body 110 in a single module by bending the end of the jointing member main body 110 from the view point of the productivity and the convenience of installation.
[61] More specifically, as shown in FIG. 2, the upper and lower panel insertion protrusions 140 and 130 are oppositely bent in the vicinity of each other.
[62] Although the concrete panel jointing member 100 may be configured as a separate member from the concrete panel 200 as described above, it may be integrated into the concrete panel 200 by insertion into the upper portion at the time of manufacturing the concrete panel 200 as shown in FIGS. 6 and 7.
[63] In this case, in order to reinforce the adhesive strength between the concrete panel
200 and the concrete panel jointing member 100, a concrete attachment reinforcing hole 131 may be formed in the center of the lower panel insertion protrusion 130, so that the concrete can be inserted into the hole 131 during the pouring (or during the arrangement of bar), and then cured together with the concrete panel jointing member 100.
[64] Hereinafter, other components of the concrete panel according to an embodiment of the present invention will be described
[65] The support member 300 comprises a wall jointing portion 310 attached to the wall
10 of a structure; a support member main body 320 extending from the wall jointing portion 310 to the concrete panel 200; and a jointing member engagement portion 330 formed in the support member main body 320 to be coupled with the support member engagement portion 120 of the jointing member main body 110.
[66] In FIG. 3, the wall jointing portion 310 of the support member 300 are bent in a L- shape with respect to the support member main body 320, and the wall jointing portion 310 is attached to the wall 10 using a bolt mechanism.
[67] The support member engagement portion 120 of the jointing member main body 110 is provided for the engagement with the support member 300, while the jointing member engagement portion 330 of the support member main body 320 is provided for the engagement with the support member engagement portion 120. These components may have any specific mechanism, and the present invention is not intended to limit this mechanism.
[68] Referring to FIGS. 2, 3, and 7, the support member engagement portion 120 has a hole as the support member engagement hole 121, and the jointing member engagement portion 330 has a hole as the jointing member engagement hole 331 so that both holes can be matched with each other from a top view, and an engagement such as a bolt-nut pair passes through them to engage them with each other.
[69] The surface of the wall 10 is generally rough or not uniform. Therefore, it would be preferable to have a means for adjusting a gap between the concrete panel 200 and the wall 10 in order to provide a flat front surface formed by a plurality of concrete panels 220 mounted on the wall 10. [70] For this purpose, as shown in FIGS. 2, 3, and 6, the support member engagement portion 120 of the jointing member main body 110 has a long hole such as the support member engagement hole 121 elongated with respect to the lower and upper panel insertion protrusions 130 and 140.
[71] In this case, when the concrete panel jointing member 100 is engaged with the support member 300 using the engagement 400, the position of the jointing member engagement hole 331 can be moved to the front and the rear along the length of the long hole 121, so that the gap between the concrete panel 200 and the wall 10 can be adjusted. As a result, it is possible to readily form a flat front surface formed by a plurality of concrete panels 200.
[72] Preferably, a reflective heat insulator 500 may be inserted into the gap between the concrete panel 200 and the wall 10 to face the inner surface of the concrete panel 200.
[73] The reflective heat insulator has a low emissivity for heat radiation, and reflects radiation heat energy to insulate and hold heat between a wall and a tile or between a wall and a interior panel in order to minimize heat discharge. This reflective heat insulator provides a significant heat-insulation effect even in a small thickness.
[74] Since the reflective heat insulator allows the concrete panel structure according to the present invention to be implemented in a minimized thickness, it can be advantageously applied to the present invention.
[75] Due to the thickness of the concrete panel jointing member 100, a gap may be generated between neighboring concrete panels. This gap is preferably filled with a filler 600 such as resin or silicon.
[76] Now, another embodiment will be described with reference to FIGS. 8 and 10, in which the filling work using the filler 600 can be omitted by removing the gap between the neighboring concrete panels.
[77] Referring to FIG. 9, the upper side of the concrete panel 200 has an upper jointing groove 210 into which the lower panel insertion protrusion 130 is inserted. Also, the front upper side of the upper jointing groove 210 is higher than the rear upper side to allow the upper side of the concrete panel 200 to have a step.
[78] In this configuration, the jointing member main body 110 of the concrete panel jointing member 100 is inserted into the space formed by the step, so that the front upper and lower sides of the neighboring concrete panels 200 can be contacted without any gap from a front view as shown in FIG. 8.
[79] Referring to FIG. 10, the lower side of the concrete panel 200 has a lower jointing groove 200 into which the upper panel insertion protrusion 140 is inserted. Also, the front lower side of the lower jointing groove 200 is lower than the rear lower side to allow the lower side of the concrete panel 200 to have a step. In this case, a similar effect can be obtained as described above. [80] More preferably, both upper and lower sides of the concrete panel 200 may have the stepped configuration as described above in association with FIG. 8. In order to allow the upper side of the upper jointing groove 210 and the lower side of the lower jointing groove 220 to be contacted without any gap from a front view while the concrete panel jointing member 100 is installed, a gap generated from the steps between the rear upper side of the upper jointing groove 210 and the rear lower side of the lower jointing groove 220 is made to have a thickness identical to that of the jointing member main body 110 of the concrete panel jointing member 100.
[81] In other words, if each of the step of the lower side of the upper concrete panel 200a and the step of the upper side of the lower concrete panel 200b has a thickness identical to about a half of that of the jointing member main body 110, it is possible to omit the filling work without generating any gap between the neighboring concrete panels 200 from a front view as well as provide a safe jointing mechanism.
[82] Furthermore, without such a configuration, it is worried that the jointing portion between the concrete panel 200 and the concrete panel jointing member 100 may be damaged when the upper concrete panel 200 is sloped toward a space between the neighboring concrete panels 200 (i.e., forwardly). However, the above configuration has an extra advantage that such a damage can be prevented.
[83] While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
