JP-A-7-275765 JP-A-2005-232675

  On the other hand, the joint between the members such as the wall plate is large or small depending on the type of the member at each construction site, or the gap width is not constant, for example, as shown in FIG. Is formed into a tapered shape that gradually narrows (expands). There has been a demand for the development of a coking nozzle device that can readily cope with such a wide variety of seams and perform coking work more simply, efficiently, and at low cost.

  The present invention has been made in view of the above-described conventional problems. One object of the present invention is to reliably caulk a seam without the need for a backup member. An object of the present invention is to provide a caulking nozzle device that can easily cope with coking.

  In order to solve the above problems, the present invention is a caulking nozzle device that caulks the joint gap H while discharging the filler (K) from the nozzle tip side to the joint gap H and moving the filler along the joint. A nozzle main body 12 connected to the accommodating portion (108), and a receiving means supported by the filler accommodating portion (108) or the nozzle main body 12 and inserted and arranged in the joint gap H from the work surface side, the nozzle main body When the nozzle main body 12 is moved along the joint line and is opposed to the 12 discharge ports 18 at a predetermined separation position (G), the filling material (K) filled in the gap H from the discharge port 18 in the discharge direction. Receiving means 14 for adhering to the opposite two faces Wa and Wb of the seam gap while holding the filler (K) at a predetermined thickness while receiving it so as to block the course, and the receiving means 14 is in the seam gap H. The filler (K) is received while the receiving width D of the filler (K) discharged from the nozzle body 12 is changed in accordance with the width of the joint gap H when moving in the longitudinal direction of the seam in the inserted state. The caulking nozzle device 10 is characterized by having a variable width structure 28. The nozzle body 12 may be formed in, for example, a substantially cylindrical body or a tapered shape that gradually becomes narrower toward the discharge port 18 on the front end side, and may be thick or thin, or any other arbitrary configuration But you can. The nozzle body 12 may be provided integrally with the filler accommodating portion or may be detachably connected. The variable width structure 28 may be configured by a single member that is elastically deformed due to material properties, such as rubber or silicon, or may be configured by combining a plurality of members, for example. As a configuration in which a plurality of members are combined, for example, as described later, it is preferable to have a configuration in which members having variable mutual gaps are arranged in parallel. The means for making the mutual separation gap J variable may be, for example, elastic deformation due to the material of the member, or a structure in which an elastic member such as a spring or rubber is interposed in the mutual gap J. The nozzle body 12 and the receiving means (14) may be integrally formed. For example, the molten resin may be poured into a mold in which the nozzle body 12 and the receiving means (14) are integrated, and the mold is formed. Good. Alternatively, the receiving means (14) may be detachably connected to the nozzle body 12 or the filler accommodating portion (108). Moreover, it is good also as having a filling thickness adjustment means which can set arbitrarily the thickness of the filler in the seam gap H thickness direction. In this case, for example, the receiving means (14) can be configured so that the connection position of the support portion to the nozzle body or the filler accommodating portion is different, or the support portion can be expanded and contracted. It is also possible to adjust the separation position by freely approaching and separating from 18 and to arbitrarily set the thickness filled with the filler. It can also be applied to both new construction and repair work on the caulking part.

  At this time, the receiving means (14) may be provided with an arm device 22 including a plurality of arms 20 that allow the separation gaps J to be variable in a direction that blocks the path of the filler (K) in the discharge direction. Even if there is a separation gap J between the arms, the caulking material K is less likely to leak from the separation gap J in the discharge direction due to high viscosity, and the coking material can be reliably received by a plurality of arms. The material of the arm 20 may be, for example, a metal such as stainless steel or iron, a hard resin such as an alloy or plastic, or any other material.

  Further, the arm device 22 is a narrow member whose one end is supported by the filler accommodating portion (108) or the nozzle body 12 and whose other end is arranged in parallel in the joint gap, and the other end is spaced from each other (J). A plurality of narrow members that open and elastically deform in the width direction as a whole may be provided. In order to fill the caulking material with a constant thickness, the narrow member easily elastically deforms in the width direction, but does not easily deform in the discharge direction of the caulking material, that is, in the depth direction of the seam gap. It may be a shape, a structure, or the like. Further, by reducing the frictional contact portion between the narrow member and the seam gap between the opposing two surfaces Wa and Wb, it can be used for a long period of time and can be smoothly moved in the gap.

  The narrow member (20) may be arranged such that one end is supported on the filler accommodating portion (108) or the nozzle body 12 side and the other end is spread radially.

  According to the caulking nozzle device of the present invention, the caulking nozzle device caulks the seam gap while discharging the filler from the nozzle tip side to the seam gap and moving along the seam, and is connected to the filler container. A receiving means, which is supported by the nozzle body and the filler accommodating portion or the nozzle body and is inserted and arranged in the seam gap from the work surface side, and is arranged to face the discharge port of the nozzle body at a predetermined separation position. When moving along the seam, the filler is adhered to the opposite two surfaces of the seam gap while holding the filler at a predetermined thickness while blocking the path in the discharge direction of the filler filled in the gap from the discharge port. Receiving means, and the receiving means joins the receiving width of the filler discharged from the nozzle body when moved in the longitudinal direction of the seam while being inserted into the seam gap. Since the variable width structure for receiving the filler while changing in accordance with the width of the gap between the eyes is provided, the receiving means can reliably caulk the seam without the need for a backup member, and the variable width structure of the receiving means. The caulking operation can be easily performed by promptly responding to various seam gaps that differ depending on the construction site without requiring other members. Therefore, since it is not necessary to prepare various types of nozzle devices at various sites and only one nozzle device is required, it is troublesome to replace the nozzle device or its constituent members at the site or to process the members for width adjustment. Since no work is required, it is easy to use, inexpensive, and highly practical.

  In addition, the receiving means includes an arm device including a plurality of arms whose variable separation gaps are variable with respect to the direction in which the path to the discharge direction of the filler is blocked, thereby allowing the various separation gaps of the arms to be varied. The receiving width can be changed smoothly according to the width of various seam gaps, and a backup member is required by using multiple arms to reliably block the path of viscous filler in the discharge direction. It is possible to perform a reliable caulking with a fixed thickness and adhesion to the two opposing surfaces.

  The arm device is a plurality of narrow members whose one end is supported by the filler accommodating portion or the nozzle body and the other end is arranged in parallel in the joint gap, and the other end is spaced apart from each other in the width direction as a whole. By providing a plurality of narrow members that are elastically deformed, the receiving means is automatically changed to a width corresponding to the gap simply by being inserted and arranged in the seam gap by elastic deformation in the width direction of the narrow member. In addition, the variable range of the width can be secured relatively large and can be widely applied from a narrow seam gap to a large seam gap.

  In addition, the narrow member has a structure in which one end is supported on the filler accommodating portion or the nozzle main body side and the other end side is radially spread so that the narrow member is elastically deformed in the width direction as a whole. The structure can be realized with a simple structure, and can be moved while smoothly elastically deforming in the width direction even when moving in a state where it is inserted and arranged in a gap whose width changes, such as a tapered seam gap. And workability is good. Furthermore, while the other end side spreads radially, a portion where the gap between the narrow members is narrow is formed at the intermediate position, so that the path in the discharge direction of the viscous filler can be well blocked and received. Improvement of the uniformity of the filler can be expected.

  The best mode for carrying out the coking nozzle device of the present invention will be described below with reference to the accompanying drawings. The caulking nozzle device of the present invention performs caulking by filling a filler for maintaining airtightness and watertightness in a seam gap formed at joints and joints between components such as inner walls and outer walls in a building, for example. When applied.

  1 to 7 show a first embodiment of a caulking nozzle device according to the present invention. The same members as those of the conventional caulking gun described in the background art will be described with the same reference numerals. The caulking nozzle device 10 according to the present embodiment is used, for example, when filling a filler in a gap H formed at a joint between members such as a wall plate W as shown in FIGS. As the filler, for example, a caulking material K (or a sealing material) such as a silicon-based or urethane-based material having a high viscosity to some extent is used. As shown in FIGS. 1 and 2, in the present embodiment, the caulking nozzle device (hereinafter referred to as “nozzle device”) 10 includes a nozzle body 12 and a receiving portion 14 that is inserted and arranged in the joint gap H. I have. The nozzle device 12 is connected to a filler accommodating portion. In this embodiment, as the filler accommodating portion, for example, a caulking gun main body 108 of a caulking gun 100 that has been widely used as shown in FIG. 14 is used. The nozzle device 10 according to the present embodiment is connected to the caulking gun main body 108 instead of the conventional nozzle 110. In addition, the filler material storage portion is not limited to a caulking gun type, but may be other things such as a tube-shaped or syringe-shaped storage container.

  As shown in FIGS. 1, 2, and 3, the nozzle body 12 is made of, for example, a hollow cylindrical body made of plastic and having communication holes 16 inside while opening both ends, and is on the base side (upper and right sides in FIG. 1). The taper is formed so as to taper from the tip side toward the tip side (the left side in FIG. 1). The base of the nozzle body 12 is connected to the front side of the caulking gun body 108 in an internal communication state. The nozzle body 12 is formed such that the internal insertion hole 16 is tapered toward the tip side in the same manner as the outer shape, and the opening on the tip side is used as the discharge port 18. The discharge port edge portion forming the discharge port 18 is inclined with respect to the axial direction of the nozzle body, that is, the communication direction of the communication hole 16. Therefore, as shown in FIG. 6, when caulking, the nozzle body 12 has the discharge port edge around the seam on the surface of the wall plate W with the axial direction inclined obliquely toward the movement direction X. In the abutted state, the wall plate surface is moved along the joint gap H with the work surface as a work surface. Thus, by forming the nozzle outlet 18 in a diagonally cut shape, the nozzle device can be smoothly moved along the seam of the nozzle device, and the workability is good. Returning to FIG. 2, the nozzle body 12 is detachably connected to the distal end side of the reduced diameter portion on the distal end side of the cylinder portion 106 of the caulking gun body 108. The nozzle main body 12 has, for example, a female screw portion 12a formed on the inner side on the base side, and is provided so as to be screwed and connected to a male screw portion provided on the distal end side of the cylinder portion 106 from the outside. The connecting portion between the nozzle main body 12 and the caulking gun main body 108 may be in a reverse mode in which a male screw portion is provided on the nozzle main body side and a female screw portion is provided on the tip end side of the caulking gun. Good. Further, the nozzle body 12 may be formed integrally with the caulking gun body 108 (filler accommodating portion). Further, the nozzle body 12 may be formed of, for example, rubber that is hard to some extent, synthetic resin, or any other material.

  As shown in FIGS. 1, 2, and 6, the receiving portion 14 is disposed to face the discharge port 18 of the nozzle body 12 at a predetermined separation position, and the wall plate W that becomes the work surface side during coking is provided. It is inserted and arranged in the joint gap H from the surface side. The receiving portion 14 receives the caulking material K from the discharge port 18 so as to block the course in the discharge direction of the caulking material K filled in the gap H when moving the nozzle body 12 along the joint. It is a receiving means for adhering to the opposing two surfaces Wa and Wb of the seam gap while maintaining the thickness. In the present embodiment, the receiving portion 14 is supported by the nozzle body 12 and moves integrally with the nozzle body 12. Further, the receiving portion 14 includes a variable width structure 28 that changes the receiving width D of the caulking material K corresponding to the width of the joint gap H.

  In this embodiment, as shown in FIGS. 3 and 4, the receiving portion 14 is arranged so as to block the course of the caulking material K filled in the joint gap H from the discharge port 18 in the discharge direction. An arm device 22 including one arm 20 is provided. Each arm 20 is made of, for example, a narrow member that is sufficiently narrow with respect to the width of the joint gap H, and is arranged in parallel in the width direction of the gap H while opening the separation gap J therebetween. The arm 20 is made of, for example, a plastic band-shaped plate member having a substantially square shape when viewed from the side. The arm 20 is opposed to the discharge port 18 of the nozzle body 12 with a predetermined separation width G and substantially receives a caulking material. The arm main body 24 and the arm support 26 for supporting the arm 20 on the nozzle main body 12 are integrally provided. The arm 20 is a narrow member in which one side on the thickness side of the substantially U-shaped plate member in a side view is opposed to the discharge port 18 side, and the arm main body portion 24 is discharged with an inclination with respect to the communication hole direction of the nozzle main body. The bending angle is set so as to be substantially parallel to the outlet edge, and the plate surface side faces the arms and the side walls (Wa, Wb) of the wall plate W. The arm 20 is arranged so that one end side of the arm support portion 26 side is integrally supported on the outer surface of the nozzle body 12 and the other end side of the arm body portion 24 is radially spread. That is, while one end side of the three substantially U-shaped arms 20 is supported and fixed as a group to the nozzle body 12, the other end sides of the arms 20 are radially expanded in three directions with a separation gap J therebetween. However, they are arranged in parallel to constitute a trifurcated arm device 22. Each arm 20 made of a narrow member can be flexed freely in the width direction in combination with the material properties, and while changing the separation gap J freely, i.e., close to and apart from each other, Can be elastically deformed in the width direction. Thereby, as shown by the solid line in FIG. 4, the arm device 22 is normally held in a shape in which the other end side of the three arms 20 is radially expanded to ensure the maximum receiving width. On the other hand, as shown by a two-dot chain line in FIG. 4, for example, when the arm device 22 is inserted and arranged in a narrow joint gap H (less than the maximum receiving width), While the end side is in contact with the opposing two surfaces Wa and Wb of the wall plate, it is elastically deformed so as to be close to each other in the width direction and is changed to a small receiving width D corresponding to the narrow width of the joint gap. When the arm device 22 is detached from the joint gap, it is elastically restored and returns to its original width. That is, when the plurality of arms 20 are inserted into the joint gap H and moved in the longitudinal direction of the joint, the receiving width D of the caulking material K discharged from the nozzle body 12 corresponds to the width of the joint gap H. Thus, the variable width structure 28 that receives the caulking material K while being automatically changed is configured. Accordingly, for example, as shown in FIG. 12, the receiving width D of the receiving portion 14 can be automatically changed from the narrow gap Hn to the wide gap Hw (indicated by a dashed line in the figure). it can. Furthermore, even when caulking a tapered seam gap Ht that gradually decreases in width as shown in FIG. 13, the width gradually decreases as the nozzle body is moved along the seam as shown in FIG. The receiving width D can be automatically changed in correspondence with the tapered seam. That is, the receiving width D can be changed corresponding to a wide variety of seams that differ from site to site without requiring any other member with only one nozzle device. As described above, the arm 20 is formed of a plate member that is a narrow member and spreads to some extent in the discharge direction of the caulking material, so that the arm 20 can easily resist the caulking material K fed from the discharge port 18 of the nozzle body. A predetermined separation position G is maintained without bending. Therefore, the arm device 22 realizes a configuration that keeps the filling thickness of the caulking material constant while facilitating elastic deformation in the width direction as a whole.

  As shown in FIGS. 1, 2, and 3, the separation space formed by the separation width G between the discharge port 18 of the nozzle body 12 and the plurality of arms 20 is at least in the seam gap width direction and the nozzle body 12. The rear side in the movement direction X is open. The plurality of arms 20 inserted and arranged in the joint gap H are arranged side by side with a separation gap J therebetween. However, since the caulking material K has a high viscosity, the caulking material discharged from the nozzle discharge port 18 side. May slightly enter the separation gap J between the arms due to its viscosity, and does not leak in the discharge direction, but is received so as to block the course of the caulking material in the discharge direction. The caulking material K is guided in the width direction of the seam gap H by the plurality of arms 20 and bonded to the side walls on both sides of the seam gap H, that is, the opposite two surfaces Wa and Wb of the gap. When the nozzle body 12 is moved along the longitudinal direction of the gap H, the caulking material K adhered to both sides of the gap is not subjected to pressure from the caulking gun body side, and the adhesive state is maintained on the wall plate by its own viscosity. Then, the caulking material is filled with a constant filling thickness corresponding to the separation width G between the arm main body 24 and the discharge port 18. Accordingly, the caulking material can be reliably and satisfactorily caulked without requiring a backup member and preventing leakage of the caulking material and three-surface adhesion. Note that the number of the arms 20, that is, the narrow members is not limited to three, and may be two or four or more arbitrary numbers. In addition, the three arms 20 are not limited to the one that radially expands the other end side. For example, the arms on both end sides are formed in an arc shape, the separation gap J gradually increases from one end side to the intermediate position, and the other end from the intermediate position. Any other configuration that can elastically deform the overall width, such as a structure in which the separation gap gradually narrows toward the side, may be used. Further, the shape, size, etc. of the arm 20 may be arbitrary. Further, for example, a cover that can be expanded and contracted may be laid on the side of the arm 20 facing the discharge port 18 of the nozzle body 12, and for example, a configuration that can be folded and unfolded like a fan may be adopted. Further, for example, an urging member such as a spring or rubber may be disposed in the arm separation gap to vary the width of the separation gap.

  Next, the operation of the coking nozzle device according to this embodiment will be described. The nozzle device 10 is connected to a filler accommodating portion such as the caulking gun body 108 and the caulking material is accommodated in the cylinder portion 106. When caulking the seam gap H of the wall plate W formed with a constant width in the longitudinal direction as shown in FIG. 12, if the receiving portion 14 is inserted and arranged in the gap H, the width of the seam gap H is reduced. The arm 20 is elastically deformed corresponding to the size (Hn, Hw), and the receiving width D is automatically changed in size. As shown in FIG. 5 and FIG. 6, the inclined surface of the discharge port edge of the nozzle body is brought into contact with the surface of the wall plate W around the seam while the receiving portion 14 is inserted and disposed in the seam gap H. Tilt the whole against. In this state, for example, by moving the entire caulking gun to move the nozzle device 10 along the seam, the trigger 104 of the caulking gun body 108 is pulled to move the caulking material K from the cylinder section 106 side to the nozzle body. And are discharged into the gap H from the discharge port 18 of the nozzle body. The discharged caulking material is received by the plurality of arms 20 of the receiving portion 14 within the gap H. At this time, the receiving portion 14 blocks the caulking material K having a viscosity discharged in a pressure-feed manner from proceeding in the discharge direction, that is, the gap thickness direction, and the thickness of the separation width G of the receiving portion 14. In addition, the caulking material is bonded to the side walls on both sides of the gap, that is, the opposite two faces Wa and Wb of the gap. When the nozzle body 12 is moved along the seam after filling with the caulking material, as shown in FIG. 11, the caulking material K bonded to the opposing two surfaces Wa and Wb does not receive the discharge pressure from the caulking gun body side, The adhesive state is maintained at a thickness corresponding to the separation width G without dripping in the thickness direction of the gap H due to its own viscosity. In this way, while filling along the seam gap, the filling thickness of the caulking material is uniformly filled to the thickness of the separation width G of the receiving surface, and at the same time, the caulking material K received by the receiving portion 14 is gapd. Guide in the width direction of H and adhere to the opposing two surfaces Wa and Wb of the gap. After filling, the coking surface is smoothed with a trowel or spatula as necessary. Thus, even if the back-up member is not filled in the gap before caulking, the caulking material is surely placed on the two opposite surfaces Wa of the wall plate W while preventing leakage, non-uniformity of the caulking material, three-sided adhesion, etc. , Good coking bonded to Wb can be performed. Similarly, when caulking the joint gap H of the wall plate W formed in a tapered shape whose width gradually narrows along the longitudinal direction as shown in FIG. 13, the receiving portion 14 is inserted and arranged in the gap H. Corresponding to the width of the joint gap H, the plurality of arms 20 are elastically deformed in the width direction as a whole, and the receiving width D is automatically changed in size. As shown in FIG. 7, in the case of the taper-shaped seam gap H, the arm 20 automatically moves as a whole in the width direction in accordance with the taper-shaped width when moved along the seam of the nozzle body. It is elastically deformed, and the receiving thickness D is changed at any time, and the course of the caulking material is blocked to keep the filling thickness of the caulking material at a predetermined thickness. The gap width of the joint is often different depending on the construction site. However, as described above, the receiving portion 14 corresponding to the gap width can be formed immediately, and a wide variety of joints can be used with only one nozzle device. Caulking can be performed smoothly and reliably.

  Next, a second embodiment of the coking nozzle device and the coking method of the present invention will be described with reference to FIGS. 8 to 10. The same members as those in the above embodiment are denoted by the same reference numerals, and detailed description will be given. Omitted. In this embodiment, the nozzle device 10a has substantially the same configuration including a nozzle body 12 and a receiving portion 14 as shown in FIGS. The form of the arm device 22 is partially different. In the present embodiment, the arm 20a disposed at the center of the three arms of the arm device 22 is formed in the flange portion 30 that extends in the width direction at the end edge portion on the discharge port 18 side of the nozzle body 12, It is formed in a substantially T shape in end view. As a result, the width of the separation gap J between the arms can be set to be relatively small. As a result, when the caulking material is received in the joint gap so as to block the course of the caulking material discharged from the discharge port 18, the caulking material is separated from the arms. It becomes difficult to enter J, and coking with higher uniformity than that of the above embodiment can be achieved. In addition, the caulking nozzle device according to this embodiment is also easy to work as in the above-described embodiment, and can exhibit effects such as simple and reliable coking according to the seam width without the need for a backup member. .

  The caulking nozzle device of the present invention described above is not limited to the configuration of the above-described embodiment alone, and may be modified arbitrarily without departing from the essence of the present invention described in the claims. Good.

  The caulking nozzle device of the present invention is suitably applied in the case of caulking (sealing) in which a filler is filled in gaps formed at joints, joints, joints, etc. between members used for interior and exterior of a building. Is done.
