Abstract

PROBLEM TO BE SOLVED: To provide a wall face structure for a building excellent in strength and beautiful appearance in a short construction period and at lower cost. SOLUTION: A joint filling member 1 is a long material with a rectangular thin plate bent and formed in a sectionally trapezoidal shape and a preset width of gap S1 is longitudinally formed between both bent ends. Panel materials 11 fixed in an base isolating building construction are independently moved when outer force is applied thereto in earthquake, to absorb the outer force. In this case, when the panel materials 11 are moved so as to expand the width of a joint gap 14, the width of the gap S1 of the joint filling member 1 is also expanded following the change of the width of the joint gap 14. Because the joint filling member 1 has elastic restoring force in quality and shape, when the width of the joint gap 14 being free of the outer force is reset, the width of the gap S1 is also reset. As a result, the separation and thus flotation of a facing material 12 from the joint filling member 1 are prevented and the deterioration in strength and beautiful appearance of the outer wall of a building is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint filling member and a wall structure, and more particularly, to a joint filling member to be fitted to joints between panel materials of a building outer wall, and a building using the joint filling member. It relates to the wall structure of an object.

[0002]

2. Description of the Related Art Conventionally, on a building outer wall having a structure in which a panel material (for example, an ALC plate, an extruded plate, a siding plate, or the like) is attached to a steel frame, a vertical wall insertion reinforcing method has been used.

In the vertical wall insertion bar construction method, a reinforcing bar is sandwiched between panel members arranged vertically, and each panel member and the reinforcing bar are adhered to each other by using a cement-based material. Also, by filling a cement-based material, the panel members are fixed to each other and the joints are sealed. But,
Since each panel material is firmly fixed with rebar and a cementitious material with high hardness, if a large external force is applied to each panel material during an earthquake, each panel material or joint may be cracked and damaged. was there.

[0004] In recent years, there has been an increasing demand for prevention of damage to buildings during an earthquake, and various seismic isolation construction methods have been proposed. A typical example thereof is a dry rocking construction method. In the dry rocking construction method, only the upper and lower parts of each vertically arranged panel material are fixed to the steel frame,
By not fixing each panel material, when a large external force is applied to each panel material during an earthquake, each panel material moves independently to absorb the external force and prevent damage to each panel material It has become.

[0005]

In a seismic isolation construction method such as a dry rocking construction method, when an external force exceeding a certain level is applied to each panel material, each panel material moves independently to absorb the external force. Has become. For this reason, the joint filling member filled between the panel materials is required to have elasticity, and a brittle material such as a cement-based material cannot be used. A sealing material made of a synthetic resin material is used. However, such a synthetic resin material having elasticity has a disadvantage that the unit price is high and the material becomes thin after curing.

In particular, ALC having low surface strength as a panel material
When a board is used, the periphery of the ALC board is subjected to chamfering of about 8 to 10 mm in order to prevent loss of the periphery of the ALC board during transportation or construction. Is required, and the above-described disadvantages become more apparent.

[0007] In recent years, in order to enhance the durability and aesthetics of the building outer wall, there has been an increasing demand for a method of finishing an outer wall in which a sheet-like surface material is attached to the surface of a panel material. As the surface covering material used here, there is a material provided with flexibility by binding crushed particles of natural stone or the like with a synthetic resin material and forming the same into a sheet shape.

When such a covering material is attached so as to cover the joints between the panel materials, if the sealing material becomes thinner after the attachment of the covering material, the sheet-like covering material will be dented, resulting in strength and aesthetics. May be reduced.
For this reason, it is necessary to affix the facing material after the sealing material is cured, and to shorten the construction period, the curing time (curing time) of the sealing material must be shortened. However, when a large amount of a sealing material made of a synthetic resin material having elasticity as described above is used, the curing time of the sealing material becomes longer, which causes a longer work period.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a joint filling member which is inexpensive and has excellent elasticity. Another object of the present invention is to provide a wall surface structure of a building which has a short construction period, is low in cost, and has excellent strength and aesthetic appearance.

[0010]

Means for Solving the Problems According to the first aspect of the present invention, which has been made to achieve the above object, a longitudinal direction is divided into a plurality of portions, and a gap (S2) is formed between the portions. The gist of the joint filling member is characterized in that the width of the gap is set according to the applied external force.

Therefore, according to the present invention, since the gap is provided between the portions, the joint filling member expands and contracts by the gap corresponding to the applied external force to absorb the external force. it can. By the way, as in the invention according to claim 2, in the joint filling member according to claim 1, each of the divided portions has an elastic shape corresponding to a cross-sectional shape of the joint into which the joint filling member is fitted. A thin plate having a restoring force has a bent shape, and a second gap (S1) is formed along the longitudinal direction of the joint between the bent both end portions of the thin plate, and the width of the second gap is You may make it set according to the external force applied.

Therefore, according to the present invention, in addition to the effect of the first aspect, since the second gap is provided for each of the portions, the voltage is applied in a direction orthogonal to the second gap. The joint filling member expands and contracts by the second gap in response to the applied external force, and can absorb the external force. That is, the external force applied in the direction of expanding and contracting the gap between
And the external force applied in the direction of expanding and contracting the gap can be absorbed.

According to a third aspect of the present invention, in the joint filling member according to the second aspect, each of the divided portions is a wall surface on which the thin plate extends between the portions. May be connected to each other. Therefore, according to the present invention, since the joint filling member can be easily manufactured by bending or extruding, if a material having a low unit price is used as the material for forming the thin plate, a sealing unit having a high unit price is provided in the joint. Can be provided at a very low cost as compared with the case of filling.

According to a fourth aspect of the present invention, in the joint filling member according to the first aspect, each of the divided portions corresponds to a cross-sectional shape of the joint into which the joint filling member is fitted. It may be made of a foam material having an elastic restoring force having a sectional shape. Therefore, according to the present invention, since each portion is made of a foam material having an elastic restoring force, it can be deformed when an external force is applied to absorb the external force.

According to a fifth aspect of the present invention, in the joint filling member according to the second or fourth aspect,
The divided portions may be connected to each other with a flexible cord. Therefore, according to the present invention, when an external force is applied, the string material bends and each part moves independently, so that the external force can be effectively absorbed.

According to a sixth aspect of the present invention, in the joint filling member according to the fourth aspect, the divided portions are connected to each other by a foam material of the same material as the respective portions. You may do so. The invention according to claim 7 is
A thin plate having elastic restoring force has a bent shape in a shape corresponding to the cross-sectional shape of the joint in which the joint filling member is fitted, and a gap is formed between both bent end portions of the thin plate along the longitudinal direction of the joint. (S1) is formed, and the width of the gap is set according to the applied external force.

Therefore, according to the present invention, since the gap is provided for each of the portions, the joint filling member expands and contracts by the gap corresponding to the external force applied in the direction orthogonal to the gap, The external force can be absorbed. Claim 8
The invention described in (1), a plurality of panel members constituting an outer wall of a building, and joints between the panel members are fitted.
And a sheet-like surface covering material attached to the panel material and the joint filling member using an adhesive so as to cover the joint filling member. The gist is a wall structure characterized by this.

Therefore, according to the present invention, since the joint filling member is excellent in elasticity, the covering material stuck on the joint filling member does not peel off from the joint filling member and does not float. Further, the outer covering material can be attached immediately after the joint filling member is fitted to the joint. By the way, as in the invention according to claim 9, in the wall structure according to claim 8, the panel material may be installed using a seismic isolation method.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) A first embodiment of the present invention will be described below with reference to the drawings. FIG.
1 is a perspective view showing a joint filling member 1 according to a first embodiment.

The joint filling member 1 is a long object formed by bending a rectangular thin plate into a trapezoidal cross section, and has a gap as a second gap having a predetermined width in the longitudinal direction between both bent ends. S1 is formed. That is, the joint filling member 1
When viewed from the cross-sectional side, the bottom surface 1a is formed by extending the upper side of the trapezoid, the upper surface 1b is formed by extending the lower side of the trapezoid, and the side surfaces 1c and 1d. Is formed with a gap S1.

The thin plate forming the joint filling member 1 is made of a material having an elastic restoring force (for example, iron, stainless steel, brass,
Various metal materials such as galvanized steel sheet and color steel sheet, synthetic resin material, synthetic resin / glass fiber composite material, etc.). Plating, painting, etc.) to give sufficient rust prevention. When the joint filling member 1 is formed using a synthetic resin material, the joint filling member 1 may be formed into the above-described shape by extrusion instead of bending.

FIG. 2 is a partially exploded perspective view showing an outer wall structure of a building using the joint filling member 1. FIG. 3 is a partial cross-sectional view showing an outer wall structure of a building using the joint filling member 1. The outer wall of the building is made of a panel material (for example, ALC) attached to a structural material (not shown) of the building such as a steel frame.
(Sheet, extruded plate, siding plate, etc.) 11 on the surface of which a sheet-like covering material 12 is adhered.

Each of the vertically arranged panel members 11 is fixed to a structural member using a seismic isolation construction method such as a dry rocking construction method. The members 11 absorb the external force by moving independently.

The exterior material 12 has a laminated structure in which a decorative material portion 12b is attached on a base material portion 12a. Base part 12
a is made of a material having sufficient tensile strength and flexibility (for example, woven fabric such as glass cloth, non-woven fabric, ceramic paper, synthetic paper, etc.), and is sufficiently thin (for example, 2 to 2) with respect to the decorative material portion 12b. (About 3 mm).

The decorative material portion 12b is formed by crushing granules of various materials (eg, natural stones, colored aggregates, colored synthetic resin materials, etc.) into synthetic resin materials (eg, synthetic resin emulsions, solvent type synthetic resins, thermoplastic type synthetic resins, etc.). ) To form a sheet.

Incidentally, a transparent resin layer for protection may be formed on the surface of the decorative material portion 12b. Further, as the decorative material portion 12b, a thin plate of various metal materials such as stainless steel or aluminum and a material obtained by applying a coating on the thin plate, or a material obtained by spraying an architectural spray material on the base material portion 12a is used. Is also good.

The peripheral portion of each panel member 11 is subjected to chamfering to prevent damage during transportation or construction, and the surface cut obliquely to the surface of the panel member 11 by the chamfering process. A take part 11a is formed. Then, in each panel material 11, an end face portion following the chamfered portion 11a is cut out to form a cutout portion 11b.

When each panel member 11 is adhered to the structural member, the sealing member accommodating portion 13 formed of a space surrounded by the cutout portion 11b of each panel member 11 has a substantially rectangular cross section with an open upper part. The joint gap 14 as a joint formed by a space surrounded by the chamfered portion 11a of each panel member 11 has a substantially trapezoidal cross section with an open upper and lower portion.

Here, the width L of the upper end opening of the joint gap 14 is set in accordance with the type, construction method, and location of the panel material 11. For example, the width L between the panel materials 11 (vertical walls) in the vertical wall insertion reinforcement method using the ALC plate as the panel material 11 or the rocking seismic isolation method is about 25 to 30 mm,
Similarly, the short joints are set to about 35 to 40 mm.

A sealing material 15 is filled in the sealing material accommodating portion 13, and the space between the panel materials 11 is sealed by the sealing material 15 so that airtightness and waterproofness can be obtained. The sealing material 15 is a material that has excellent sealing properties and is easy to fill (for example, synthetic resin materials such as aqueous acrylic, modified silicon, and one-component urethane).
Consists of

The joint filling member 1 is fitted in the joint gap 14, and the bottom surface 1e of the joint filling member 1 is fixed on the sealing material 15 using a fixing member 16 such as an adhesive or a double-sided tape. In this state, the joint gap 14
The gap S1 of the joint filling member 1 is arranged along the longitudinal direction of the joint. That is, in the joint filling member 1, the gap S1 is formed along the longitudinal direction of the joint gap 14 between the bent both ends of the thin plate.

An exterior material 12 is adhered to the surface of each panel material 11 and the upper surface 1f of the joint filling member 1 using an adhesive 17. The adhesive 17 is a material that can securely adhere the panel material 11 and the joint filling member 1 to the base member 12a of the surface covering material 12 and has elasticity after curing (for example, the same material as the sealing material 15). , Elastic bond, etc.).

When the outer wall of the building is constructed, each panel material 11 is attached to the structural material of the building, and the sealing material 1 is placed in the sealing material accommodating portion 13 of each panel material 11.
The process up to filling 5 is undertaken by a base construction company, and the subsequent process is undertaken by a finisher. Therefore, the finisher first fits the joint filling member 1 into the joint gap portion 14, then fixes the bottom surface 1 e of the joint filling member 1 on the sealing material 15 via the fixing member 16, and subsequently, With respect to the surface of each panel material 11 and the upper surface 1f of the joint filling member 1;
The adhesive 17 is applied at a time using an applicator such as a trowel or a roller, and finally, the outer covering material 12 is attached so as to cover the joint filling member 1 between the panel materials 11. When the adhesive 17 is applied, a slight amount of adhesive is applied to gaps between the joint gaps 14 and the side surfaces 1c and 1d of the joint filling member 1 and gaps such as inside the gaps S1 of the joint filling member 1. The agent 16 may be pushed in.

According to the outer wall structure of the building using the joint filling member 1 of the first embodiment configured as described above, the following operations and effects can be obtained. (1) In the outer wall structure of the present embodiment, since the seismic isolation construction method is used, when an external force of a certain degree or more is applied to each of the panel members 11, each of the panel members 11 moves independently to reduce the external force. Absorb.

At this time, if each panel material 11 moves so that the width of the joint gap 14 is expanded, the joint gap 1
4, the gap S1 of the joint filling member 1
Also expand the width. When each panel material 11 moves so that the width of the joint gap 14 is reduced, the joint gap 1
4, the gap S1 of the joint filling member 1
Is also reduced. Here, since the joint filling member 1 has an elastic restoring force due to its material and shape, when the joint filling member 1 is released from the external force and the width of the joint gap 14 returns to its original state, the width of the gap S1 also returns to its original state.

As described above, the width of the gap S1 changes, so that the joint filling member 1 follows the movement in the direction perpendicular to the gap S1 and parallel to the upper surface 1b (the direction of the arrow AA '). Expand and contract. The arrow A in the joint filling member 1
The expansion and contraction width in the −A ′ direction is determined by the width of the gap S1 and the outer dimensions and material of the joint filling member 1 in a normal state. Therefore, if the expansion width is set large, it is possible to obtain the joint filling member 1 that can sufficiently absorb a large external force.

Further, since the adhesive 17 has elasticity, the joint gap 14 and each of the side surfaces 1 c and 1 of the joint filling member 1 are formed.
Even when a small amount of the adhesive 16 is pressed into the gap between the joint filling member 1 and the gap portion S1 of the joint filling member 1, the upper surface 1b of the joint filling member 1 is covered with the outer surface when the gap S1 expands and contracts. The fixation with the material 12 via the adhesive 17 is reliably maintained.

Therefore, even when a large external force is applied to the joint filling member 1 during an earthquake, the surface covering material 12 does not peel off from the joint filling member 1 and does not float, and the strength and appearance of the building outer wall may be reduced. Absent. The width of the gap S1 in the steady state may be optimally set based on the seismic intensity specified by the seismic isolation construction method and the expansion and contraction width of the joint filling member 1 in the direction of the arrow AA '. For example, the joint filling member 1 specified at the seismic intensity 7 under the seismic isolation
When the width of expansion and contraction in the direction of the arrow AA ′ is about 10 mm, the gap S1 can slide 10 mm.
It may be set to open to the extent.

(2) Since the joint filling member 1 has a simple shape and can be easily manufactured by bending or extrusion molding, if a low-priced material is used as the material for forming the thin plate, the joint filling member 1 can be formed. Compared to the case where the sealing material having a high unit price is filled in the interior of the housing 14, it can be provided at a very low cost.

(3) Since the joint filling member 1 has an elastic restoring force, the joint filling member 1 is not deformed due to a change with time after being fitted in the joint gap 14. Therefore, unlike the case where the sealing material is filled in the joint gap portion 14, the problem that the surface material floats from the joint due to thinning does not occur.

(4) Since the joint filling member 1 is fixed to the sealing material 15 by using the fixing member 16, the fixing member 16
Even if an adhesive is used, the joint filling member 1 can be attached in a very short time. Therefore, there is no need for a hardening time (curing time) which is required when the sealing material is filled in the joint gap 14, and the construction period can be shortened.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to the drawings. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

FIG. 4 shows a joint filling member 21 according to the second embodiment.
FIG. The joint filling member 21 is composed of portions 21a having the same dimensions and shape. Each part 21a
A rectangular thin plate is bent and formed into a trapezoidal cross section, and a gap S1 is formed in the longitudinal direction between both bent ends. That is, when each portion 21a is viewed from the cross-sectional side, the upper surface 1b includes a bottom surface 1a having an upper side of a trapezoid extending, an upper surface 1b having a lower side of the trapezoid extending, and side surfaces 1c and 1d. A gap S1 is formed between the side surface 1c. Then, the bottom surface 1a extending between the portions 21a
Are connected to each other, and a gap S2 having a predetermined width is formed between the portions 21a.

That is, the joint filling member 21 is formed on each surface 1 except for the bottom surface 1a of the joint filling member 1 of the first embodiment shown in FIG.
b to 1d are divided in the longitudinal direction into a plurality of portions 21a, and a gap S2 is formed between the surfaces 1b to 1d of each portion 21a. Note that punching molding may be used to form the gap S2.

FIG. 5 is a partially exploded perspective view showing the outer wall structure of a building using the joint filling member 21. Since the seismic isolation construction method is also used in the outer wall structure of this embodiment, when an external force of a certain degree or more is applied to each panel member 11, each panel member 11 moves independently to absorb the external force.

At this time, similarly to the first embodiment, each panel material 1 is so formed that the width of the joint gap 14 is expanded or reduced.
When 1 moves, the width of the gap S1 of the joint filling member 21 also expands and contracts following the change in the width of the joint gap 14.
That is, as the width of the gap S1 changes, the joint filling member 21 expands and contracts following the movement in the direction (the direction of the arrow AA ′) that is orthogonal to the gap S1 and parallel to the upper surface 1b.

When the vertically arranged panel members 11 move so as to be displaced from each other, the width of each gap S2 of the joint filling member 21 also expands and contracts in accordance with the movement. Here, since the bottom surface 1a has an elastic restoring force, when the bottom surface 1a is released from an external force, the width of the gap S2 also returns to the original position. That is, by changing the width of the gap S2, the joint filling member 21
It expands and contracts following the movement in the direction (arrow BB 'direction) orthogonal to the gap S2. In addition, the expansion and contraction width of the joint filling member 21 in the direction of the arrow BB ′ is the gap S2 in the normal state.
And the material of the joint filling member 21.

Accordingly, the joint filling member 21 is formed by the arrow A
It expands and contracts in two directions of -A 'direction and arrow BB' direction.
Since a pitching occurs in addition to the rolling at the time of the earthquake, each panel member 11 performs a complicated movement in which the pitching and the rolling are combined. On the other hand, the joint filling member 21 corresponds to the arrow A
By expanding and contracting in the -A 'direction, an external force caused by the roll is absorbed, and by expanding and contracting in the direction of the arrow BB', the external force caused by the pitch is absorbed. Therefore, if the expansion width in each direction is set large, it is possible to sufficiently absorb the large external force applied in the two directions.

Since the adhesive 17 has elasticity, the joint gap 14 and the side surfaces 1 c,
1d and each gap S1, S2 of the joint filling member 21.
Even when a small amount of the adhesive 16 is pushed into the gaps such as the inside, when the gaps S1 and S2 expand and contract,
Adhesive 1 between upper surface 1b of joint filling member 21 and surface material 12
The fixation via 7 is reliably maintained.

Therefore, even when a large external force is applied to the joint filling member 21 during an earthquake, the surface covering material 12 does not peel off from the joint filling member 21 and does not float, and the strength and appearance of the building outer wall may be reduced. Absent. Note that the width of the gap S2 in the steady state may be optimally set based on the seismic intensity defined by the seismic isolation construction method and the expansion and contraction width of the joint filling member 21 in the direction of the arrow BB ′. For example, the expansion and contraction width of the joint filling member 21 in the direction of the arrow BB ′ is 10 m.
If it is about m, the width of the gap S2 may be set to about 10 mm.

In the second embodiment, the first
The same effects as (2) to (4) of the embodiment can be obtained. Next, each modified example in which a part of the second embodiment is changed will be described with reference to the drawings. In each modification, the same components as those of the joint filling member 21 of the second embodiment have the same reference numerals, and a detailed description thereof will be omitted.

In the modification shown in FIG. 6, a through hole 21b is formed in a bottom surface 1a extending between the portions 21a, and narrow portions 21c left on both sides of the through hole 21b in the bottom surface 1a. Are connected to each other 21a. The through holes 21b may be formed by punching. In this modification, since the width of each portion 21c is narrow, even when an external force is applied in the direction in which each portion 21c is twisted (the direction of the arrows CC ′), each portion 21c easily follows the movement thereof. Can be twisted. Depending on the state of the ground during an earthquake, the panel members 11 may make complicated movements such that the panel members 11 are twisted with each other. Even in such a case, the respective portions 21c are twisted to absorb the external force applied to the joint filling member 21. be able to. Therefore, according to this modified example, it is possible to easily cope with the complicated movement of each panel material 11 and reliably prevent the outer covering material 12 from peeling off from the joint filling member 21 and floating.

In the modification shown in FIG. 7, each portion 21a is connected by two flexible cords 22. Each cord 22 is bonded to both ends of the bottom surface 1a of each portion 21a. Have been. In this modified example, when an external force is applied, the string material 22 bends and the respective portions 21a can move completely independently of each other, so that the complicated movement of each panel material 11 can be more reliably handled. can do.

(Third Embodiment) Next, a third embodiment of the present invention will be described with reference to the drawings. In the third embodiment, the same components as those in the second embodiment have the same reference numerals, and a detailed description thereof will be omitted.

FIG. 8 shows a joint filling member 31 according to the third embodiment.
FIG. The joint filling member 31 is composed of trapezoidal column-shaped portions 31a having the same dimensions.
A string 32 having flexibility is inserted through the string a and is connected in a rosary, and a gap S2 having a predetermined width is formed between the portions 31a by the string 32. Each portion 31a is made of a foamed material obtained by foaming various polymer materials (for example, styrene, polyethylene, polypropylene, chloroprene, neoprene, polyurethane, etc.) into a sponge shape, and has an elastic restoring force.

FIG. 9 is a partially exploded perspective view showing the outer wall structure of a building using the joint filling member 31. FIG.
FIG. 2 is a partial cross-sectional view showing an outer wall structure of a building using a joint filling member 31. Since each portion 31a is made of a foam material and has an elastic restoring force, each panel member 11 is formed such that the width of the joint gap portion 14 is expanded or reduced as in the first embodiment.
Is moved, each portion 31a is deformed following the change in the width of the joint gap 14. Further, even when the panel members 11 move so as to be shifted from each other or move so as to twist each other, since the respective portions 31a are connected by the flexible cord material 32, the respective portions 31a are completely independent of each other. By following and moving, it follows the movement of each panel material 11. Therefore, also in the third embodiment, the same effect as the modification shown in FIG. 7 can be obtained.

The panel material 11 and the joint filling member 31
Adhesive 17 for adhering the base material portion 12a of the cover material 12
It is necessary to take into consideration the adhesiveness with the foam material forming each part 31a. Moreover, the string material 32 may be formed using the same material as each part 31a, and in that case, the joint filling member 31 can be integrally formed.

It should be noted that the present invention is not limited to the above embodiments, but may be modified as appropriate without departing from the spirit of the invention. For example, the cross-sectional shape of the joint filling members 1 and 21 is not limited to a trapezoidal shape, and may be an appropriate shape (for example, a rectangle, a polygon, or a circle) that matches the cross-sectional shape of the joint gap 14.

As shown in FIG. 11, a plurality of granules 41 of an appropriate size and shape made of a foam material having elastic restoring force are accommodated in the joint gap 14, and the granules 41 are bonded to each other by the adhesive 17. The joint filling member 42 may be configured by binding. In this case, each of the granules 41 is deformed when an external force is applied.
The external force can be reliably absorbed, and the same effect as in the third embodiment can be obtained.
