(Construction method)
Next, an outer wall panel coupling method using the outer wall clamping device A according to the first embodiment will be described.
When the outer wall panel 20 is attached to the skeleton structure 10, the frame member 21 of the outer wall panel 20 is pressed against the column 11, the two beams 12 and 13, and the intermediate columns 14 and 15 of the skeleton structure 10 as shown in FIG. 2. . In this state, a plurality of rivets 30 are fastened from the interior IN side of the inter-columns 14 and 15, and a plurality of fixings are arranged at predetermined intervals in the vertical direction across the frame member 21 and the column 11 at the side end surface portion. The plate 30 (connector) 30c is fixed to the frame member 21 and the column 11 by screws 30b from the side surfaces, and the outer wall panel 20 is coupled to the skeleton structure 10.

  In this connection, as shown in FIG. 2, the outer wall panel 20 is attached to the skeletal structure at the upper and lower corners of the both ends in the horizontal direction of the outer wall panel 20 using the outer wall clamping device A of the first embodiment. The joining work is performed after the 10 columns 11 and the floor beams 13 (or the ceiling beams 12) are brought into contact with the columns 14 and pressed.

  Hereinafter, an operation procedure for pressing the outer wall panel 20 against the skeleton structure 10 by the outer wall clamping device A will be described. In this description, a lower corner of the outer wall panel 20, that is, a column 11 and a floor beam 13 are formed. An example in the vicinity of the corner portion to be described will be described, and the upper corner portion of the outer wall panel 20 is the same operation, and thus description thereof will be omitted.

At the time of this construction, first, the pressing operation cam member 50 is inclined with respect to the horizontal direction so that the front end surface 52a of the cam portion 52 is downward as shown in FIG. And the cam portion 52 are relatively wide.
Then, the operator holds the handle 44 and holds the outer wall clamping device A at a predetermined height, that is, in the example of the lower end portion of the outer wall panel 20, the lower end of the device main body 40 is the height of the lower end of the outer wall panel 20. As shown in FIG. 2, the skeleton structure 10 is disposed at a height that is close to the frame body 10 so that the outer wall panel 20 and the pillar 11 are sandwiched between the pressing piece 41 of the apparatus main body 40 and the pressing operation cam member 50. In addition, the pressing piece 41 of the apparatus main body 40 is brought into contact with the outer surface 22 a of the outer wall panel 20, and the cam surface 52 b of the cam portion 52 is brought close to or in contact with the indoor surface 11 b of the column 11.

Next, the operator rotates the pressing operation cam member 50 in the horizontal direction as indicated by an arrow R in FIG. 1 while maintaining the height of the outer wall clamping device A.
By the rotation of the pressing operation cam member 50, the interval between the cam portion 52 and the pressing piece 41 is relatively narrowed, and the contact position of the cam portion 52 with respect to the column 11 changes from the cam surface 52b to the tip surface 52a side. Along with this, the support shaft 43 is moved in a direction away from the indoor surface 11 b of the column 11, the pressing piece 41 strongly presses the outer wall panel 20, and the outer wall panel 20 presses strongly against the column 11, the floor beam 13, and the intermediate column 14. It is done.

  Then, as shown in FIG. 3, when the front end surface 52a of the cam portion 52 of the pressing operation cam member 50 comes into full contact with the indoor surface 11b of the column 11, a restriction force against further rotation acts. The clamped state is such that the outer wall panel 20 and the column 11 are sandwiched between the pressing piece 41 and the pressing operation cam member 50. At this time, the pressing force applied to the outer wall panel 20 by the outer wall clamping device A can be adjusted by the total length of the pressing operation cam member 50, that is, the cam portion 52 is rotated in advance with respect to the operating rod 51 and the female screw (The illustration is omitted) The meshing position of the male screw 51b is changed and adjusted to an optimum length.

  In such a clamping state by the outer wall clamping device A, the outer wall clamping device A is maintained attached to the skeletal structure 10 even if the operator releases his hand from the handle 44. Therefore, the operator removes the hand from the handle 44 and performs the operation of coupling the outer wall panel 20 to the stud 14 with the rivet 30, the screw 30b, and the fixing plate 30c as described above.

(Effect of Embodiment 1)
According to the outer wall clamping device A of the first embodiment, the following effects can be obtained.
a) When the outer wall panel 20 is coupled, the outer wall panel 20 is strongly pressed against the column 11, the floor beam 13, and the inter-column 14 by the pressing piece 41 of the outer wall clamping device A. Therefore, the rivet 30, the screw 30b, and the fixed The outer wall panel 20 is not lifted from the pillar 11 or the floor beam 13 at the time of connection by the plate 30 c for use.
Therefore, a step can be prevented from occurring on the surface of the outer wall panel 20 that is fixed to the building unit next to each other, or the step can be kept lower than before, and the surface step adjustment performance can be stabilized and improved. Can do.

  b) At the time of the coupling work using the rivet 30 screw 30b and the fixing plate 30c, the operator does not need to suppress the outer wall panel 20, and can perform the coupling work alone from the room IN side.

  c) The pressing piece 41 has a vertical dimension capable of pressing the floor beam 13 and the stud 14 at the same time, and the outer wall panel 20 is reliably and simultaneously secured to the floor beam 13 (the ceiling beam 12 is also the same) and the stud 14. The surface step adjustment performance can be more reliably stabilized and improved in such a manner that there is no gap between the outer wall panel 20 and the floor beam 13 (ceiling beam 12) and the inter-column 14. Can do.

  d) Since the two pressing operation cam members 50 are arranged side by side, the outer wall panel 20 can be uniformly pressed even when the pressing piece 41 has a long vertical dimension.

  e) The pressing operation cam member 50 is rotatably attached to the support shaft 43, and the interval between the cam portion 52 and the pressing piece 41 is changed only by rotating the pressing operation cam member 50. Easy and excellent workability. Moreover, the pressing operation cam member 50 has a lever ratio of L1: L2 obtained by lengthening the input side of the operation rod 51 based on the position of the rotation hole 51a. Suppresses and is excellent in operability.

f) When the pressing operation cam member 50 is leveled, the cam portion 52 is formed with a front end surface 52a that comes into contact with the interior surface 11b of the column 11, and an inclined cam surface 52b is formed around the front end surface 52a. did. For this reason, when the space | interval of the cam part 52 and the press piece 41 becomes the narrowest, the front end surface 52a hits the indoor surface 11b of the pillar 11, and can maintain the state. That is, the clamp state of the outer wall clamping device A can be stably maintained, and the workability is excellent.
Moreover, since the cam surface 52b comes into contact when the pressing operation cam member 50 is rotated in the horizontal direction from the inclined state, the operation force can be reduced as compared with the case where the cam surface 52b is not formed.

  g) In the pressing operation cam member 50, the operation rod 51 and the cam portion 52 are formed separately, and both are coupled by a female screw and a male screw 51b so that the axial dimension thereof can be adjusted. Thereby, the pressing force at the time of clamping by the outer wall clamping device A can be arbitrarily adjusted. In addition, since the adjustment of the axial dimension is performed by a simple screw, it is advantageous in terms of cost, and the axial dimension hardly changes when the outer wall panel 20 is pressed.

  h) A handle 44 is provided on the apparatus main body 40 of the outer wall clamping apparatus A. Therefore, at the time of construction, the handle 44 can be held and the outer wall clamping device A can be attached to the skeletal structure 10, and the workability is excellent compared to the case where the handle 44 is not provided. .

(Embodiment 2)
The second embodiment is different from the first embodiment in the pressing operation member and the support member.
That is, the apparatus main body 240 includes a pressing piece 241 and a side piece 242 that have the same L-shaped cross section as in the first embodiment, and is supported as a support member that faces the pressing piece 241 integrally with the side piece 242. A piece 243 is provided.

  Further, the support piece 243 is provided with support holes 243a having a female screw (not shown) on the inner periphery in parallel at two locations on the top and bottom.

A pressing operation rod 250 is provided in the support hole 243a as a pressing operation member.
A male screw 251 that meshes with a female screw (not shown) of the support hole 243a is formed on the outer periphery of the tip portion that is the first end portion in the axial direction of the pressing operation rod 250. By rotating about the shaft, the shaft is supported so as to be movable in the axial direction, that is, in a direction approaching and away from the pressing piece 241.
In addition, an operation rod 252 is provided at a proximal end portion that is a second end portion in the axial direction of the pressing operation rod 250 so as to protrude in the axis orthogonal direction.

  Therefore, at the time of construction by the outer wall clamping device of the second embodiment, at the time of clamping, the operation rod 252 is held, the pressing operation rod 250 is rotated around the axis, and the tip thereof is directed to the indoor surface 11b of the column 11. The pressing piece 241 presses the outer wall panel 20 by the pressing force. Note that the distal end surface of the pressing operation rod 250 is formed in a circular shape having the same size as the outer peripheral diameter, similar to the base end shown in FIG.

  Even in the outer wall clamping device according to the second embodiment configured as described above, the effects a), b), c), d) and h) are achieved for the same reason as in the first embodiment.

  In the second embodiment, the pressing operation rod 250 has the male screw 251 that meshes with the female screw of the support hole 243a of the support piece 243, and moves in the axial direction only by rotating. Even if the standards of the outer wall panel 20 (for example, the dimensions of the pillars 11, the beams 12, 13, and the spacers 14, 15 and the thickness of the outer wall panel 20) are different, The outer wall panel 20 and the pillar 11 having various dimensions are sandwiched between the pressing piece 241 and the pressing piece 241 so that the outer wall panel 20 can be reliably pressed against the pillar 11, the floor beam 13, and the intermediate pillar 14.

  Further, since the operation rod 252 is provided on the pressing operation rod 250, a lever ratio can be obtained during rotation, and the operability is excellent.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to such embodiment, A various deformation | transformation and substitution can be added in the range which does not deviate from the summary of this invention.

For example, the support shaft 43 shown in the first embodiment is bent into an L shape, It is good also as a structure couple | bonded with the press piece 41 directly. Even in the second embodiment, the support piece 243 and the pressing piece 241 may be coupled by a rod-like material other than the metal plate, for example.

  Further, in the embodiment, an example in which two pressing operation cam members 50 and two pressing operation rods 250 as pressing operation members are provided is shown, but the number of pressing operation members is arbitrary, and is 1 or 3 or more. A plurality of these may be provided.

  In the embodiments, rivets, screws, and fixing plates are shown as coupling members for coupling the outer wall panel to the studs, but other means such as bolts may be used.

  Moreover, in embodiment, although the column-shaped press operation cam member 50 and the press operation rod 250 were shown as a press operation member, the shape is not restricted to a column shape, Other columnar shapes, such as a polygonal thing, are shown. A thing, a plate-shaped thing, etc. may be used.
