Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a construction method for retrofitting a surface mounting panel to a wall surface of a building frame such as a concrete structure, and positioning and fixing the surface mounting panel to the wall surface during the retrofitting. It is related to the adjustment jig.

<Prior art> The wall surface of a building body such as reinforced concrete may be covered with a required surface mounting panel for the purpose of external design, heat insulation, and protection of the base.

FIGS. 7 (a) to 7 (d) are explanatory views showing a procedure for retrofitting a mounting panel to a building wall in the prior art.

That is, first, the unevenness of the surface of the building wall B is corrected, and after finishing mortar floating treatment or the like to adjust the groundwork, the covering attachment positions of the plurality of mounting panels P to be attached are marked out. Based on the above marking, the adhesive 1 is attached to a suitable number of places on the wall surface serving as the mounting surface of the cover panel P by dango-like or thick coating (FIG. 7A).

Next, small pieces of packing 2 are attached by adhesion or the like to, for example, four locations corresponding to the attachment surface of the building panel B on the building panel B so that a part thereof faces the end side of the covering panel P (seventh example).
Figure B). As shown in FIG. 7 (c), this packing 2 is such that when the mounting panel P is attached to the building wall B, the surface of the mounting panel P is positioned at a preset finishing surface level and is finished as a whole as a flat surface. Building wall B with exterior panel P
To adjust the position from. Therefore, the thickness of the packing 2 varies depending on the part of the building wall B.

After the packing 2 is attached and joint packing, joint material, etc. are arranged around the panel in order to secure a joint width interval with the adjacent panel, the mounting panel P is bridged between the corresponding packings 2 and pressed (7th). Figure c). The required number of the exterior panels P are attached to the building wall B based on the allocation by marking. Therefore, packing 2
In order to make the number of used panels small and to carry out a rational construction, the adjacent mounting panels P are arranged so as to partially abut each other as described above.

By pressing the front panel P shown in FIG. 7C, the front panel P is temporarily supported by the adhesive 1. Then, while keeping this positioning state pressed and supported by hand, the fixing bolt 3 is then screwed into the building wall B from the surface of the mounting panel P with a required tool or the like, and the mounting panel P is permanently attached to the building wall B (see FIG. 7D). ).

Then, the joints 4 formed between the adjacent cover panels P are filled with a joint treatment material, and the surface of the cover panel P is treated with an appropriate finishing material as required to obtain a final finish.

<Problems to be Solved by the Invention> However, the above-described positioning and fixing work of the mounting panel P has the following problems.

That is, the packing 2 is dotted on the building wall B, and the thickness cannot be subtly changed. Therefore, even if it is possible to mount the surface mounting panel P or a partial surface composed of several surface mounting panels P with good accuracy, it is not satisfactory in terms of the flatness of the entire mounting surface. was there. If the overall flatness is not good, the appearance of the building will be poor if the building wall is an outer wall. In this case, since the packing 2 is covered with the cover panel P, it is very difficult to rework it as a post-process, which is practically impossible. Therefore, the mounting work of the packing 2 is troublesome and requires carefulness. Also,
The front panel P also needs to be pressed and supported by hand until it is finally fixed by the fixing bolt 3, which also complicates the work.

Further, since the work of adjusting the entrance / exit of the cover panel P, mounting, and fixing are performed for each cover panel P, it takes time to change the setup and the workability cannot be improved.

Further, the front panel P is usually fixed by the fixing bolt 3 before the adhesive 1 is solidified. Therefore, the fixing bolt 3 is excessively tightened, the adhesive 1 is crushed, and the mounting panel P is crushed.
It sometimes caused problems such as warping.

The present invention has been made in order to solve the above-mentioned conventional problems, and it is possible to easily and accurately adjust the mounting position of a cover panel, and to press and support the cover panel by hand until it is fully attached. It is an object of the present invention to provide a method of retrofitting a mounting panel that can be easily and accurately mounted without any need, and an adjusting jig for positioning the mounting panel that is suitable for use in this construction.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the construction method of the present invention uses a plurality of position adjusting jigs in which panel receiving nuts are adjustably attached to screw shafts protruding from the anchor portion. , The anchors are fixed to the joints between the mounting panels, which are set by the layout of the building walls, and the panel receiving nuts are rotated to adjust the position. , The retaining nut is screwed into the screw shaft of the position adjustment jig from the outside of the mounting panel, and the mounting panel is sandwiched between the panel receiving nut and temporarily fixed, and the finished surface level of the mounted mounting panel is adjusted. After the readjustment is set according to the unseasoned condition, the mounting panel is permanently fixed to the building wall with the fixing bolt, and then the holding nut is removed.

In addition, in order to adjust and fix the exterior panel from the building wall surface to a predetermined finishing surface level, a position adjustment jig that supports at the joint position between the exterior panels is attached to the building wall. A projecting screw shaft, a panel receiving nut that is adjustably screwed into the screw shaft, and an engaging means of an adjusting tool that is inserted from the joint portion is formed on the plate surface, and a screw shaft that is adjustably screwed into the screw shaft. And a holding nut for supporting the outer panel from the outside so as to be sandwiched between the panel receiving nut and the panel receiving nut.

<Operation> By rotating the panel receiving nut of the position adjustment jig with the adjusting tool from the outside of the cover panel through the joint gap, the mounting position of the cover panel after temporary fixing can be readjusted and stable. Can be positioned easily. Therefore, if the exterior panel is fixed to the building wall with fixing bolts, the overall construction can be performed with high accuracy such as flatness.

Also, after the above-mentioned final attachment, the holding nut can be removed from the screw shaft, and the mounting panel can be mounted so that the remaining position adjusting jig and the fixing bolt firmly fix the position.

The position adjusting jig used for the above-mentioned construction is arranged at the joint position between the outer panels. Therefore, it is possible to perform simple handling without requiring special processing of the mounting panel for supporting by the position adjusting jig. Further, since the entire finishing surface level can be readjusted after the cover panel is temporarily fixed, the post-installation can be performed with higher accuracy. Since the front panel can be temporarily fixed and supported by the position adjusting jig until the final fixing with the fixing bolt, it is not necessary to manually press and support until the final fixing. Therefore, workability can be improved.

<Example> Hereinafter, a preferred example of the present invention will be described with reference to the drawings.

FIGS. 1 (a) to 1 (e) are explanatory views showing a procedure for retrofitting a mounting panel on a building wall in an embodiment of the present invention, and FIG. 2 shows a position adjusting jig used in the above-mentioned construction. FIG. 3 is a front view of a main part illustrating an arrangement position, FIG. 3 is an explanatory view of operating means of a panel receiving nut of a position adjusting jig, and FIG. 4 is a position adjusting jig showing a state in which a mounting panel is temporarily fixed to a building wall. It is a structure sectional view showing one example.

First, the structure of the position adjusting jig for the cover panel used when performing the construction according to the present invention will be described with reference to FIG.

In the figure, reference numeral 10 indicates the entire position adjusting jig.
An anchor portion 11 of the position adjusting jig 10 is a plate-like member that is fixed to the building wall B. Reference numeral 12 denotes a screw shaft having a screw engraved on the outer periphery, which is integrally provided on a plate-shaped anchor portion 11. Reference numeral 13 is a panel receiving nut, which is screwed into the screw shaft 12 as a plate so that the position can be adjusted freely. The panel receiving nut 13 has a means for engaging a required adjusting tool, for example, an engaging hole 13a, near the center of its plate surface. The engagement holes 13a are symmetrically formed at two places around the screw hole into the screw shaft 12, and the bifurcated adjustment tool T is inserted into the engagement hole 13a to rotate the panel receiving nut 13. (See Figure 3). In order to execute this rotation operation, not only the hole shape but also the groove shape or the projection shape may be used.

Reference numeral 14 denotes a cap nut, which includes a cap nut portion 14a screwed into the screw shaft 12, a flange portion 14b that abuts against the surface mounting panel P, and a nut head 14c. In this case, flange 14b
In order to prevent the surface of the mounting panel P from being damaged by the rotation when screwed as the holding nut 14, it is preferable that the cap nut portion 14a is not integrated with the cap nut portion 14a but can be mutually rotated as shown in the figure. Further, the nut head 14c is also shaped to engage with a tool such as a spanner in the illustrated example, but it may be shaped to be operated by hand like a wing nut.

A required number of position adjusting jigs 10 having the above structure are prepared in advance.

Then, first, the mounting position of the covering panel P is assigned to the building wall B by marking out or the like. This allocation is performed corresponding to the joint line of the required width formed by attaching the exterior panel P to the building wall B. Then, according to this allocation, the position adjusting jig 10 and the dango-shaped or thick-coating adhesive 1 are attached to the building wall B (FIG. 1A). The position adjustment jig 10
The anchor portion 11 of the position adjusting jig 10 is positioned and fixed at the position where the joint line intersects. FIG. 2 shows the intersection position of the joint line Ba by the four cover panels P, but in addition to this, it is formed by the T-shaped joint line formed by the two cover panels P and one cover panel P. There is a right angle joint line. Therefore, in other words, the front panel P
The position adjusting jig 10 is arranged outside the corner Pc. In this embodiment, the above-mentioned arrangement position is used in order to reduce the number of position adjusting jigs 10 to be used, but the arrangement position is not particularly limited as long as it is arranged on the joint line Ba.

Next, the panel receiving nuts 13 are screwed into the screw shafts 12 of the respective position adjusting jigs 10. Since the preset finishing surface level of the cover panel P and the preset thickness of the cover panel P are known, the panel receiving nut 13 is adjusted to a position in consideration of these. Then, a joint packing joint material (not shown) or the like is arranged around the cover panel P in order to secure a joint width interval with the adjacent cover panel P.

In FIG. 1 (B), the mounting panel P is bridged between the panel receiving nuts 13, and the pressing nut 14 is screwed into the screw shaft 12 of the position adjusting jig 10 from the outside, and the flange portion 14b and the panel receiving nut 13 are inserted. 6 and 7 show a state in which the cover panel P is temporarily fixed to the building wall B (see the enlarged view of FIG. 4). In this case, the corner portion Pc of the mounting panel P has the position adjusting jig 10
As shown in FIG. 3, at least the engagement hole of the panel receiving nut 13 is not arranged to abut the protruding screw shaft 12.
The adjustment tool T is engaged with the outer side 13a from the outside and is spaced at a distance that does not hinder the rotation of the panel receiving nut 13. This interval is the so-called joint width.

After the temporary fixing, the flatness of the entire mounting surface of the mounting panel P and the deviation from the finished surface level are measured again, and the holding nut 14 at the defective portion is removed and readjusted with the adjusting tool T (Fig. 1C). ).

After the above readjustment, the removed retaining nut 14 is screwed in again, and then the fixing bolt 15 is screwed into a prepared hole previously drilled in the building wall B from an appropriate portion of the mounting panel P by a vibration drill to tighten it (Fig. 1D). This completes the attachment of the exterior panel P to the building wall B. This mounting panel P is a position adjustment jig
The position is fixed by being sandwiched between the panel receiving nut 13 and the holding nut 14 of 10. Therefore, the tightening and tightening of the fixing bolt 15 does not cause the ingress / egress position of the front panel P to be inadvertently displaced.

After the above tightening, the cap nut 14 is removed (Fig. 1E), the joint line Ba is filled with the joint treatment material in the same manner as the known means, and, if necessary, a decorative coating or the like is spread over each of the mounting panels P. It is done and the finish is completed.

In the construction method described above, the adhesive 1 is also used for temporarily fixing the exterior panel P to the building wall B, but if the above function of the position adjusting jig 10 is taken into consideration, the adhesive 1 is used. Even if it does not, the construction of the present invention is possible.

Further, although the exterior panel P is a two-layer composite panel in the illustrated example, this has a composite function of providing a heat insulating material P ₂ inside the exterior material P ₁ as an outer heat insulating panel when the building wall B is an outer wall, for example. Is taken into consideration and is not necessarily limited to this.

In this case, when the heat insulating material P ₂ of the cover panel P is vulnerable to local pressure such as urethane, the pressing nut is used.
Due to the pressing of 14, the heat insulating material P ₂ is partially recessed, which may cause a step between the mounting panels P. In order to prevent this, for example, a part of the cover panel P with which the panel receiving nut 13 abuts is reinforced, or the axial length of the cap nut portion 14a of the press nut 14 is made equal to the thickness of the cover panel P. Can be considered. The cap nut 14a is mounted on the front panel P
If the axial length is the same as the thickness, the screwing of the holding nut 14 can be restricted by abutting against the panel receiving nut 13, so that the pressing force of the holding nut 14 can be prevented from being excessively applied.

Further, the present invention is not a special construction means used only for the outer wall, and it can be applied as it is to the surface mounting of the inner wall.

FIG. 5 is a perspective view showing another embodiment of the holding nut 14 in FIG. 4 and an example of the shape and configuration of the adjusting tool T ₁ associated therewith.

That is, in the embodiment shown in FIG. 4, when the panel receiving nut 13 is readjusted after the front panel P is temporarily fixed, it is necessary to remove the holding nut 14 (see FIG. 1C).

It is the holding nut 21 shown in FIG. 5 that can be improved by further improving the workability.

In the figure, the position adjusting jig 20 includes an anchor portion 11, a screw shaft 12, a panel receiving nut 13, and a holding nut 21 according to this embodiment, which are the same as those in the above embodiment.

The cap nut 21 is a cap nut portion 21a screwed into the screw shaft 12.
And a flange portion 21b abutting against the mounting panel P and a nut head 21c provided with a handle for rotation. The cap nut portion 21a and the nut head 21c are integral with each other, and the flange portion 21b is not integral with the nut head 21c and the like as in the above-described example, but is rotatable with respect to each other. And the flange portion 21b
Around the nut head 21c, there is formed an arc-shaped long groove 22 through which an insertion leg of an adjusting tool described later is inserted. In the case of the illustrated example, they are symmetrically provided at two places.

Adjustment tool T ₁ for engaging and rotating the panel receiving nut 13
Is an insertion leg Ta on one end side of the cylinder and an engagement protrusion T on its tip.
b is formed. The insertion leg Ta has a length such that the long groove 22 formed in the flange portion 21b of the holding nut 21 is inserted so that the engagement protrusion Tb at the tip can reach the engagement hole 13a of the panel receiving nut 13. Therefore, in the case of the example shown in FIG.
₁ has an inner diameter enough to swallow the nut head 21c.

According to this, when readjusting the panel receiving nut 13,
It is not necessary to remove the holding nut 21 as in the above embodiment, and the workability is improved accordingly. In addition, 11a is an anchor portion 11
This is an attachment index displayed on the surface of the anchor portion 11, and is displayed in accordance with the marking out of the joint line Ba of the building wall B to which the anchor portion 11 is attached, so that the anchor portion 11 is positioned for attachment to the building wall B. Work can be performed easily.

FIG. 6 shows another embodiment of the position adjusting jig 30 used in the construction of the present invention. That is, in the position adjusting jig 10 according to the embodiment shown in FIG. 4, the cap nut portion 14a of the pressing nut 14 is screwed into the screw shaft 12. Therefore, the width of the joint line Ba formed by the cover panel P is determined by the cap nut portion 14a.
May be affected by the dimensions of the above, and depending on the thickness of the mounting panel P, it is necessary to prepare various screw shaft lengths.

In view of this, in the embodiment shown in FIG. 6, the screw shaft 31 is a cylindrical screw shaft formed with the inner screw portion 31b in addition to the outer screw portion 31a, and the adapter bolt 32 is screwed into the inner screw portion 31b. The adapter bolt 32 has a full-threaded outer circumference in its entire length. Further, the shaft length is set to an appropriate length such that when the mounting panel P is received by the panel receiving nut 33, one end is screwed into the screw shaft 31 so that the free end side is sufficiently projected from the mounting panel P.

The adapter bolt 32 is screwed with a holding nut 34a having a flange portion 34b in a mutually rotatable manner, for example, in the form of a wing nut, so that the cover panel P is sandwiched between it and the panel receiving nut 33. According to this, the joint line Ba of the cover panel P may have a width in consideration of the insertion operation of the adjustment tool for rotating the panel receiving nut 33.

When the position adjusting jig 30 according to this embodiment is used, the member to be removed after the mounting of the front panel P to the building wall B is the adapter bolt 32 and the holding nut 34a having the flange portion 34b.

According to the position adjusting tool 30 of this embodiment, the jig action and the like are
Although it is similar to the position adjusting jig 10 of the illustrated embodiment, it can be used for constructing the mounting panel P of various thicknesses only by changing the length of the adapter bolt 32.

In each of the position adjusting jigs 10, 20 and 30, the anchor portions 11 and 35 are formed of plate-shaped members, but this is not limited to this configuration as long as it can be fixed to the building wall B.
For example, a form such as a self-piercing anchor embedded in the building wall B or a wedge can be used. In this case, the anchor parts 11,3
5 and the screw shafts 12 and 31 have a single shaft shape in appearance.

Also, in this case, the anchor portions 11, 35 and the screw shaft 12,
31. Further, if a material having a good heat insulating property such as nylon is used for the adapter bolt 32 and the like, the screw shaft 12 and the like do not cause a cold / heat bridge action and prevent the building wall B from being adversely affected by dew condensation or the like. be able to. Further, in this configuration, the cutting workability of the screw shaft 12 and the adapter bolt 32 is secondarily improved, so that the position adjustment of the outer surface of the mounting panel P and the tip end of the screw shaft 12 and the like can be easily performed. Become.

<Effects of the Invention> As described in detail above, according to the construction method of the present invention, it is possible to easily attach the mounting panel without setting the ground treatment such as the unevenness of the building wall, and to set it with high accuracy. The workability is greatly improved.

And each work can be organized as a continuous flow work without performing the work such as adjusting the entrance / exit of the cover panel, mounting / fixing, etc. for each cover panel, improving efficiency through learning, shortening the time required for setup change, etc. The workability is improved.

Furthermore, since it is not necessary to press and support by hand when attaching the exterior panel to the building wall, safety and workability are significantly improved.

Further, according to the position adjusting jig of the present invention, the panel mounting nut and the pressing nut can accurately position and securely hold the front panel. In particular, since the flatness and the position error of the entire surface can be reconfirmed and readjusted after positioning and provisionally fixing each of the mounting panels, the construction can be performed with higher accuracy.
