Embodiments of the present invention will be described below with reference to the drawings.

Example 1 Two wall panels 20, using the pressing jig according to this example,
A work structure in which the upper end surface of 30 is flush will be described with reference to FIGS. 2 to 4.

FIG. 1 is a sectional view showing the structure of a pressing jig of Example 1 according to the present invention. FIG. 2 shows the pressing jig 10.
It is a perspective view which shows the state which makes the upper end surface of two wall panels 20 and 30 flush by using. FIG. 3 is a perspective view showing a state in which the two wall panels 20 and 30 are joined together. FIG. 4 is a cross-sectional view showing a state in which the upper ends of the two wall panels 20 and 30 are flush with each other using the pressing jig 10.

The structure of the pressing jig 10 will be described with reference to FIG. As shown in FIG. 1, the pressing jig 10 is a substantially ladle-shaped rigid member, and includes the locked portion 12, the pressing portion 16, and the grip portion 18.
It is composed of Further, the locked portion 12 and the pressing portion 14
And are connected by a first arm 13 which is a rod-shaped rigid member.

The locked portion 12 is a rod-shaped rigid member, one end of which is bent at a right angle and has a sharpened tip portion 12a, which can be fixed to a part of a wall panel 30 described later. .

Further, the pressing portion 16 and the grip portion 18 are connected by a second arm 17 which is a rod-shaped rigid member.

The pressing portion 16 is provided so as to project at a right angle from one end of the first arm 13 or the second arm 17, and has a contact surface portion 16a at one end thereof, and the corresponding contact surface portion 16a is a wall described later. It is formed flat and smooth so that the upper end surface of the panel 20 can be pressed statically.

The grip portion 18 is a rod-shaped rigid member having a function as a lever, and one end of which is provided with a manually operable hand rest 19. The hand contact 19 has irregularities that a human fingertip can contact, and the material thereof is preferably rubber, plastic, or the like, which has a good feel to the touch.

As described above, since the locked portion 12 and the pressing portion 16 and the pressing portion 16 and the grip portion 18 are connected and integrated with each other, the grip portion 18 is operated by operating the grip portion 18. In conjunction with the first arm 13, the pressing portion 1
6 and the second arm 17 move in the same direction as the grip 18. At this time, the locked portion 12 also performs the same movement, but when the point C of the tip portion 12a is used as a fulcrum, the pressing jig 1
Since 0 rotates about the point C, as a result, the point C
Is fixed, but the locked portion 12 moves.

Next, the structural characteristics of the pressing jig 10 will be mechanically described with reference to FIG.

Here, each point and each variable are defined as follows.

C: fulcrum (fixed point) D: point of action (focus) E: force point G: force point when the second arm 17 is virtually steep H: virtual contact surface of the pressing portion 16 16a when projecting downwardly: Point F ₁ : Force applied to point E of grip 18 F ₂ : Force applied to point D of pressing part r ₁ : Radial vector at point E centered on point C r ₂ : radial vector R at point D centered on point C: radial vector r at point G centered on point C when the second arm 17 is virtually steep Radial vector a _{1 at} a point H centered on a point C when the abutting surface portion 16a of the portion 16 is projected downward: length a ₂ of a vertical line dropped from the point C onto the direction line of the force F 1 a: point The length h of the vertical line drawn from C onto the direction line of the force F2: Distance of the vertical component of the radial vector r2 U: Second arm 1 The length of the theta: the length U of the second arm 17 is constant, the displacement slope angle in the case where the second arm 17 to the steep virtually (0 ≦ θ ≦ π /
2) At this time, an effective pressing jig can be designed if the following conditions are satisfied.

(1) When the radius vector r1 shown in FIG. 1 is large, the length U of the second arm 17 is constant and the angle θ is large (where 0 ≦ θ ≦ θmax and 0 ≦ θmax ≦ π / 2, θmax = a
rccos (a ₂ / (a ₂ ² + h ² ) ^1/2 )) When balanced in the state of FIG. 1, the moment of the force around point C is constant, so point C of force F 2 acting on point D
Moment of surrounding force and point C of force F ₁ acting on point E
It is equal to the moment of the surrounding force, r ₁ × F ₁ = r ₂ ×
It becomes F ₂ . Therefore, F ₂ = (r ₁ / r ₂ ) F ₁ .

Now, assuming that the length U of the second arm 17 is constant and the second arm 17 is virtually displaced by the angle θ shown in FIG. Since the radial vector R at the point G to be processed is R> r ₁ , at this time, F ₁ , r ₂ =
If constant, the force F = (R / r ₂ ) F ₁ > acting on the point D>
It becomes F ₂ .

Therefore, as the angle θ is displaced, R becomes larger and F becomes larger, and it becomes possible to apply a large force in the pressing portion 16 with a small force in the grip portion 18.

However, since the radial vector R becomes maximum when r ₂ // R, the angle θ is 0 to satisfy r ₂ // R θmax = arccos (a ₂ / (a ₂ ² + h ² ) ^1/2 )).

The length U of the second arm 17 is changed to be long (at this time, the angle θ is constant and a ₁ is large). In this case as well, the radius vector R is R> r ₁ as described above. The larger the length of the second arm 17, the larger F becomes, and it becomes possible to apply a large force in the pressing portion 16 with a small force in the grip portion 18.

Therefore, the steeper the second arm 17 with respect to the horizontal plane and the larger its length, the stronger the pressing force can be obtained.

(2) When the radial vector r ₂ shown in FIG. 1 is small now, when the distance h is virtually reduced or the distance a ₂ is reduced, the radial vector r at the point H is r <r _2. The force acting on this point H is F = (r ₁ / r) F ₁ > F ₂ , and the smaller the distance h is and the smaller the distance a 2 is, the larger F is, and the smaller the force at the grip portion 18 is, the greater the force at the pressing portion 16 is. It becomes possible to apply force.

Therefore, as the contact surface portion 16a of the pressing portion 16 projects downward and the length of the first arm 13 is shorter, a stronger pressing force can be obtained.

Considering the above points (1) and (2),
In the pressing jig 10, the second arm 17 is steep with respect to the horizontal plane and its length is large, and the contact surface portion 16 of the pressing portion 16 is large.
As a is projected downward and the length of the first arm 13 is shorter, it is possible to apply a larger force on the pressing portion 16 with a smaller force on the grip portion 18.

Next, a structure relating to a construction method for joining the two wall panels 20 and 30 will be described with reference to FIGS. 2 to 4.

As shown in FIGS. 2 and 3, the wall panel 20

Further, as shown in FIG. 3, steel plate gussets 40 are provided at the upper ends of the face members 21 and 31 fixed to both surfaces of the wall panels 20 and 30, respectively. The steel plate gusset 40 is a member for reinforcing the corner portion of the frame, that is, the joint between the vertical frame core material and the horizontal frame core material, and increasing the rigidity of the frame body. Fixed by.

As shown in FIG. 2, a plurality of female connecting fittings 44 are attached to the end face of the vertical frame core member 32 in the joining direction. On the other hand, as shown in FIG. 3, a plurality of male connecting fittings 42 are attached to the end face in the joining direction of the vertical frame core member 22. When the wall panel 20 and the wall panel 30 are joined and fixed, the female connecting fitting 44 and the male connecting fitting 42 are engaged with each other.

As shown in FIG. 3, a rectangular hole 38 is formed in an end portion of the horizontal frame core member 36, and has a size such that the engaging portion 12 and the protruding portion can be inserted. Have. Also,
A rectangular hole 34 is formed in one surface of the wall member 30 of the vertical frame core member 32, and has a size such that the protrusion of the locked portion 12 can be inserted therethrough.

At the time of joining the wall panels, as shown in FIG. 3, a guide 50 having a U-shaped vertical cross section is attached to the end of the upper end surface 20a of the wall panel 20 with its end projecting. A disc-shaped set screw 52 is provided on one surface of the guide 50, and fixes the wall panel 20 and the guide 50.

Next, the construction method according to this embodiment will be described with reference to FIGS.

At the construction site, the wall panel 30 is erected on the floor formed in the building construction area. After one wall panel 30 is erected, another wall panel 20 joined to the side surface of the wall panel 30 is lifted and moved by a crane or the like. At this time, as shown in FIG. 2, the end face having the female connecting fitting 44 and the holes 34 and 38 is oriented in the joining direction of the wall panel 30 which is installed upright, and another wall panel 20 is provided.
The end face having the male connecting fitting 42 is oriented in the joining direction of. As shown in FIG. 3, a guide 50 is provided on the upper end surface of the other wall panel 20 on which the male connecting fitting 42 is provided in advance so that one end of the guide 50 protrudes, and the guide 50 is separated from the guide 50 by a set screw 52. And the wall panel 20 of.

As shown by an arrow B in FIG. 3, another wall panel 20 to which the guide 50 is attached is suspended from above the end surface of the wall panel 30 by a crane, and two wall panels 2 are attached.
Contact 0 and 30. After the tip of the protruding guide 50 is brought into contact with the upper end portion of the wall panel 30, the set screw 52 of the guide 50 is loosened to move the guide 50 to another wall panel 20.
Remove from. Immediately before this contact, the male connecting fitting 4
2 and the female connecting fitting 44 are in a semi-engaged state. At this time, the upper end surface 20a of the other wall panel 20 has a slight protrusion on the upper end surface 30a of the wall panel 30.

After that, the tip portion 12a of the locked portion 12 of the pressing jig 10 is inserted into the hole 38 of the wall panel 30 in the downward direction,
Next, it moves laterally to bring the tip portion 12a into contact with the hole 34.

The contact surface portion 16a of the pressing portion 16 is brought into contact with the end portion of the upper end surface 20a of another wall panel 20, and the lever-shaped grip portion 18 is rotated clockwise as indicated by arrow A in FIG. The upper end surface 20a of the wall panel 20 is pressed by the contact surface of the pressing portion 14 by pressing, and the wall panel 20 can be pressed downward with a relatively small operating force by the lever principle. At this time, the male connecting fitting 42 and the female connecting fitting 44, which were in the semi-engaged state, are completely engaged. This gives 2
The work of joining the wall panels 20, 30 is completed.

As described above, according to the present embodiment, the holes 34 and 38 for fixing the pressing jig are provided in advance at the factory stage, and the pressing jig 10 is used at the construction site. Panels can be connected to each other without damaging the surface of the wall panel, and the assembling accuracy of the building panel can be improved.

Workability on site is improved.

Further, the present pressing jig can gradually compress the wall panel by the static pressure applied by the principle of leverage, and compared with the conventional case of hitting with a hanging arrow (or hammer), each of the upper surfaces of the panel is deformed by deformation. It is possible to reduce the mounting error of the members and perform reliable joining. Further, the construction jig can be applied to other building panels than the wall panel.

Second Embodiment Next, a second embodiment according to the present invention will be described with reference to the drawings. The members having substantially the same structure as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

FIG. 5 is a sectional view showing a state in which the upper ends of the two wall panels 20 and 30 are flush with each other by using the pressing jig 60 according to the present invention.

The pressing jig 60 shown in FIG.
Similar to the above, it includes the locked portion 62, the pressing portion 66, and the grip portion 68, and the principle and the like are exactly the same.

However, the locked portion 62 is a rod-shaped steel member and has a sharpened tip portion 62a with one end bent at a right angle, but unlike the first embodiment, the tip portion 62a has a pressing portion 66. And project in the opposite direction. This is to enable fixing to the back surface 36a of the horizontal frame core member 36 of the wall panel 30. Thereby, it can be applied to a wall panel or the like in which the hole 34 is not formed.

Third Embodiment Next, a third embodiment according to the present invention will be described with reference to the drawings. The third embodiment is an example showing a case where the pressing portion is provided with a height adjusting mechanism in the second embodiment. Therefore, detailed description of members having substantially the same configuration as the second embodiment will be omitted.

FIG. 6 is a sectional view showing a pressing jig 110 according to the third embodiment of the present invention. FIG. 6A is a height adjusting mechanism 11.
6 is extended downward, (B) is a height adjustment mechanism 116
Shows the state of contraction. FIG. 7 is a cross-sectional view showing a state in which the upper end surfaces of the two wall panels 130 and 140 are flush with each other using the pressing jig 110 according to the present invention. FIG. 8 is a cross-sectional view showing a joined state of two wall panels using the pressing jig 110, (A) showing a joined state at a right angle,
(B) shows a state where they are joined at a right angle, and (C) shows a state where they are joined in a normal straight line.

As shown in FIGS. 6 and 7, the pressing jig 11
0 is composed of a locked portion 111, a grip portion 112, and a pressing portion 114, as in the first and second embodiments. The pressing portion 114 and the grip portion 112 are connected by an arm 113 which is a rod-shaped rigid member. Further, a height adjusting mechanism 116 is provided below the pressing portion 114.

As shown in FIG. 6, the height adjusting mechanism 116 is formed as a rotation-linear motion converting mechanism using a screw or the like. That is, the height adjusting mechanism 116 includes the screw hole 118 formed on the main body side of the pressing jig 110 and the screw hole 1
And a screw shaft 120 screwed to the screw shaft 18. Further, the wall panel 130 is provided at one end of the screw shaft 120.
A contact surface portion 122 is formed to contact with the contact surface portion 1
22 is flat and smooth so that the upper end surface of the wall panel 130 can be pressed statically.

Further, the height adjusting mechanism 116 includes the screw shaft 12
By rotating 0 rightward or counterclockwise as indicated by α in FIG. 6A, it is possible to adjust the height in the vertical direction as indicated by β in FIG. 6A. At this time, it is preferable that the threaded portion between the screw shaft 120 and the screw hole 118 has a structure that is sufficiently strong to withstand the pressing load of the pressing jig 110.

Further, a locked portion 111 is projected from the lower portion of the pressing portion 114. This is the contact surface portion 122.
This is because unless the lower end of the locked portion 111 is formed below, the locked portion 111 cannot be locked in the hole formed in the core material described later. Compared to the pressing jig 60 of the second embodiment, the height adjusting mechanism 116 is provided, so that the rod-shaped screw shaft 120 that can project downward can be inserted into the pressing portion 114. The height of the portion 114 is high. Therefore, the thickness of the core material of the various wall panels to be pressed does not change, and the locked portion 11
Since the entire height of 1 must also be maintained, the locked portion 111 is projected from the lower portion of the pressing portion 114.

Next, the joint structure of the wall panels 130 and 140 to which the pressing jig 110 is applied will be described.

As shown in FIG. 7, the wall panel 130 (14
0) forms a frame body with a core material 132 (142) framed in the shape of a square frame, and a face material 134 (144) is fixed to one surface of the core material, and siding 138 (148) is further provided thereon.
It is a so-called wall panel with siding that is attached at the factory stage. At this time, the upper ends of the sidings 138 (148) project above the upper end surfaces of the wall panels 130 (140). A state in which the wall panels with siding are joined at right angles is the joining structure shown in FIG. 7.

In the corner portion of FIG. 7, the barrel difference 150 is integrally fixed to the core material 142 of the one wall panel 140 in advance, and is shown in the first and second embodiments (FIG. 4). Alternatively, a female connecting fitting (not shown in FIG. 7) is provided on the barrel difference 150 side, that is, the wall panel 140 side, and a male connecting fitting (not shown in FIG. 7) is the core member 132 (as shown in FIG. 5). Side, that is, the wall panel 130 side. Further, in the corner portion, a corner siding 152 is formed in advance at one end on the siding 148 side of one wall panel 140 so as to cover the body difference 150. The corner siding 152 may be affixed on site. Furthermore, one wall panel 140
The core member 142 of the
Is formed with a hole 146.

Next, the reason for installing the height adjusting mechanism 116 will be described.

When the pressing jig 110 according to the third embodiment is used in a joining structure for joining the wall panels 130 and 140 at a right angle as shown in FIG. 7, for example, the following problems can be considered. .

That is, as shown in FIG. 4 or FIG. 5, the wall panel (hereinafter referred to as the female side) to which the female connecting fitting is attached must be fixed in advance when the wall panels are joined together. After that, since the male side is hung and joined,
The protrusion of the step as shown in FIG. 7 always occurs on the wall panel side (hereinafter referred to as the male side) to which the male connecting fitting is attached. Therefore, it is necessary to abut the pressing portion 114 on the end surface of the male wall panel 130.

In the case of the joining structure for joining the wall panels 130 with siding to each other in an ordinary straight line, as shown in FIG. 8C, a pressing jig having the height adjusting mechanism used in the second embodiment is not provided. At 60, avoid the line of the siding 138 (that is, without intersecting the siding 138 and the arm portion connecting the grip portion 68 and the pressing portion 66 of the pressing jig 60), and press the pressing jig 60. Can be pressed.

However, as shown in FIG. 8 (A), when the siding-equipped wall panels 130 and 140 are joined at a right angle, the siding 138 attached to the other wall panel 130 to be pressed is shown in FIG. As shown in FIG. 3, the inclination angle θ of the arm 113 portion that projects from the upper end surface of the wall panel 130 and that connects the grip portion 112 and the pressing portion 114 is set in advance. In the jig, when the grip 112 is rotated, the grip 112
The part of the arm 113 connecting the pressing portion 114 with the upper end of the siding 138 comes into contact with each other, and each wall panel 130.
It is considered that the end faces of 40 cannot be pressed until they are flush with each other. Alternatively, it is conceivable that the upper end of the siding 138 will be damaged if forced to press.

Further, the position of the hole 146 formed in the core member 142 for locking the locked portion 111 of the pressing jig 110 is such that the position shown in FIG. Panel 14
Since it is arranged at 0, for example, siding 13
In order to avoid interference with 8, the contact surface portion 122 does not come into contact with the upper end surface of the male-side wall panel 130 and the male-side wall is pressed, as shown by γ in FIG. 8A. The panel 130 cannot be pressed.

On the contrary, as shown in FIG. 8B, the same problem occurs when the wall panel 140 side is pressed. In this case, the wall panel 130 is the female side and the wall panel 140 is the male side. The hole 136 that locks the locked portion 111 of the pressing jig 110 is provided on one wall panel 130 side.

That is, also in this case, when the pressing jig 110 is tried to be pressed, the arm 113 is siding 1
If the grip portion 112 comes into contact with the upper end of the wall 48 and tries to rotate the grip portion 112 forcibly, the siding 148 is damaged and the grip portion 112 can be rotated to press the upper end surface of the wall panel 140. Can not. Further, even if the position of the arm 113 of the pressing jig 110 is displaced as indicated by δ shown in FIG. 8B in order to avoid interference with the line of the siding 148, the contact surface portion 122 is separated from the upper end surface of the wall panel 140. It comes off and cannot be pressed.

Then, as shown in FIG. 7, the height adjusting mechanism 116 rotates the screw shaft 120 to rotate the contact surface portion 12.
2 is projected downward. At this time, the total height x of the pressing portion 114
₁ is set so that the upper end of the siding 138 projects from the upper end surface of the wall panel 130 by a protruding height x ₂ or more. By doing so, the grip 112, including the arm 113, is set to a higher position than when the screw shaft 120 is not projected downward, and the siding 140 is kept in a state where the grip 112 is not rotated. The upper end of the wall panel 130 can be pressed in the state as shown in FIG. 8A or 8B without interfering with the arm 113 portion.

As described above, the pressing portion 1 of the pressing jig 110
If the height position of the contact surface portion 122 is adjusted and the height position of the grip portion 112 is set to be high by providing the height adjusting mechanism 116 to the siding unit 14, the siding that is previously attached and fixed to the wall panel at the factory stage. The arm 113 portion of the pressing jig 110 does not come into contact with or interfere with the upper end position of the press tool 110, and the press tool 110 is ready for pressing.

The reason why the height adjusting mechanism 116 as described above is provided is not limited to the above-described reason, but as in the first and second embodiments, the mounting height due to the stroke of the male and female metal fittings when mounting various wall panels together. One of the reasons is that it can handle large and small errors. For example, the height position of the height adjusting mechanism 116 can be adjusted as described above according to the magnitude of the mounting height error such as x ₃ shown in FIG. 7.

The height adjusting mechanism 116 as described above is
It can be modified as shown in <1><2><3> shown below.

<1> A similar effect can be obtained with a mechanism constituted by a height adjusting mechanism 160 using a rod 164 as shown in FIG.

Specifically, the height adjusting mechanism 160 includes a rod 166 which is a rigid member of a rectangular rod extending from the pressing portion 114 to the end face of the other wall panel 130, and the rod 16

As described above, according to this embodiment, since the height adjusting mechanism 116 is provided, the height of the contact surface portion 122 can be adjusted, and the pressing jigs of Embodiments 1 and 2 perform the pressing work. Even when the siding-equipped wall panels 130 and 140 come into contact with each other at right angles, as shown in FIG. 7, the screw shaft 120 of the height adjusting mechanism 116 is projected downward and the height of the grip portion 112 is not obtained. By setting the position higher without changing the inclination angle of the arm 113, the arm 113 connecting the pressing portion 114 and the grip 112 is
It can be pressed without coming into contact with a member to be pressed at the time of pressing, and the bonding jig according to the present invention can be used in any bonding structure, and workability at the site is improved.

Further, due to the principle of the rotation-linear conversion mechanism, the wall panel can be gradually compressed by the static pressure load, and the mounting error of each member due to the deformation of the panel end surface can be reduced as compared with the case of hitting with a conventional hammer. Therefore, reliable joining can be performed.

Further, since it is possible to compress the panels corresponding to various panel sizes, the pressing jig can be applied to other building panels other than the wall panels. This is because the panel for construction is manufactured according to the standard dimension in the panel construction method.
This is because by drilling 65 at a predetermined position, it can be applied to various building panels used in the panel construction method.

The present embodiment is not limited to the above embodiment, but various modifications can be made within the scope of the invention. For example, the third embodiment has been illustrated as a modification of the second embodiment in which the tip end portion is hooked on the horizontal frame core material.
Modifications may be made in the first embodiment.

If a pressing force is applied to the panel by the operating force or other driving force of the operator, the pressing part and the grip part may use a cam or the like, a screwing type, or the like. The work load is further reduced by adopting various methods. Further, even if a fixture with a rod is adopted for the locked portion, the work load is further reduced.

Further, as long as it has a rotation-linear conversion mechanism, the cylindrical worm gear, the hourglass worm gear, etc. can be modified.

Furthermore, an angle adjusting mechanism capable of adjusting an inclination angle with respect to the grip portion may be provided at a portion of the arm portion connecting the grip portion and the pressing portion, which is close to the push portion. By doing this, it is possible to adjust to the optimum pressing angle,
With the reduction force applied by the grip portion, a high pressing force generated in the pressing portion is generated, and the wall panel can be pressed so as to reduce the burden on the operator.
