Description

TECHNICAL FIELD The present invention relates to a paving material pressure-adhering apparatus and a pressure-adhering method, and more particularly, paving in which a tape-shaped paving material wound in a roll is pressure-adhered to a construction surface having an L-shaped cross section. TECHNICAL FIELD The present invention relates to a pressure-adhering device and a pressure-adhering method for materials.

Conventionally, in order to prevent rainwater from entering from the joints and edges of asphalt pavement, a molded joint material molded into a tape shape has been used. Various apparatuses for attaching to a surface have also been proposed, as seen in Patent Documents 1 and 2, for example.

However, the molded joint material targeted by these conventional pasting machines is a tape-shaped joint material having a substantially constant cross-sectional shape, which is used, for example, at the joints of asphalt pavement or at the edges of pavement to prevent rainwater from entering. Even if you try to stick it on a vertical surface such as the seam between a car and a curb, the vertical cross section of the joint usually has unevenness and dust. There was a drawback that it was difficult to make sure it adhered.

In order to solve such drawbacks, the present applicant has developed a molded joint material molded into a tape shape having depressions for folding along an assumed folding line on one or both sides, and disclosed in Patent Document 3. Disclosed. Since this molded joint material has a dent for bending, it can be easily bent into an L-shape, and both the horizontal surface and the rising surface of the cut end surface of the L-shaped cross section that occurs during repair work by, for example, the cutting overlay method. It is an extremely excellent molded joint material that can be adhered to and adhered to the joint, and can effectively prevent rainwater from penetrating through the joint.

However, since the molded joint material that can be bent into the L-shape is attached to both the horizontal surface and the rising surface of the cut end surface of the L-shaped cross section, it is possible to It cannot be applied using an application device that is intended for application exclusively to vertical surfaces.

In order to solve this problem, the present applicant has proposed a paving material pressing and adhering device that includes a paving material holding part that rotatably holds a roll of paving material and a pressure adhering wheel that is inclined from the horizontal. developed and disclosed in Patent Document 4. According to the device disclosed in Patent Document 4, the tape-shaped paving material is pressed against both the unwinding of the paving material from the roll and the horizontal and vertical rising surfaces of the cut end surface of the L-shaped cross section. , can be pressed and pasted. As a result, the worker can stick the paving material such as the molded joint material in a standing position, thereby greatly reducing the burden on the worker.

However, according to subsequent findings independently obtained by the present applicant, in the device disclosed in Patent Document 4, when the construction section becomes longer, the tape-shaped pavement material is likely to be removed from the initial setting. It has been found that there is a problem that the setting position of the tape-shaped pavement material must be corrected each time the cutting end surface of the L-shaped cross section is deviated from the position. In this regard, the device disclosed in Patent Document 4 still leaves room for improvement.

Instead of pressing the tape-shaped pavement material, first, only the upper side part along the longitudinal direction of the tape-shaped pavement material is pressed to the upper corner part of the construction surface with an L-shaped cross section, and the pavement material is positioned by sticking it. Then, push the substantially central part of the paving material into the inner corner of the construction surface with an L-shaped cross section, and push the paving material extending on both sides of the inner corner so that the tip has an angle that fits the inner corner. By pressing and sticking to both the horizontal surface and the rising surface of the construction surface with a pressing ring, there is little positional deviation, and the tape-shaped pavement material is continuous on both the horizontal surface and the vertical rising surface of the construction surface with an L-shaped cross section. It has been found that the adhesive can be pressed and adhered.

A side pressing device.

In a preferred embodiment, the first support mechanism comprises means for adjusting the angle of inclination of the contact surface of the roll support from the horizontal. , and the height of the vertical rising surface on the L-shaped construction surface can be appropriately adjusted by adjusting the angle of inclination.

In another preferred aspect, the second support mechanism includes biasing means for biasing the side pressure rollers downward. It becomes possible to press the material more reliably.

In a preferred aspect of the present invention, the device for pressing the tape surface of the tape-shaped pavement material is a first pressing ring rotatably supported around a support shaft, the outer peripheral end face of which is and a second pressure ring rotatably supported around a support shaft, the outer peripheral end face of which protrudes radially at a substantially right angle over the entire circumference. The second pressing ring, a plane including the apex of the outer peripheral end surface of the first pressing ring protruding at an acute angle, and a plane including the apex of the outer peripheral end surface of the second pressing ring protruding at a substantially right angle are on the same plane. Further, the outer peripheral end surface of the second pressing ring protruding at a substantially right angle contacts both the lower surface and the rising surface rising from the lower surface of the L-shaped cross-sectional construction surface existing in the stepped portion.

In a preferred embodiment, the second pressing ring includes an upper half ring and a lower half ring having a truncated cone shape with the same bottom radius, and the upper half ring and the lower half ring face each other with their bottom surfaces facing each other. Each of them is rotatably supported independently around the support shaft which passes through the center of both bottom surfaces and is perpendicular to both bottom surfaces. As a result, the pressing wheels rotate independently to press and stick the paving material to the horizontal lower surface of the construction surface having an L-shaped cross section and to press and stick the paving material to the vertical rising surface. It becomes possible to carry out independently, and positional deviation of the tape-shaped pavement material can be further reduced.

Preferably, the angles formed by the bottom and side surfaces of the truncated cones of the upper half ring and the lower half ring are approximately 45 degrees, respectively. This coincides with the angle of the internal corner of the L-shaped construction surface.

As long as it can be pressed and adhered to both surfaces, it may be made of any material, such as rubber, synthetic resin, or metal. However, considering that the construction surface of the L-shaped cross section usually has some unevenness, at least the surfaces of the upper and lower half rings that constitute the second pressure ring and the second pressure ring should be elastic. It is preferably made of natural or artificial rubber with

In addition, the present invention is a pressure-adhering method for pressure-adhering a tape-shaped paving material to a work surface having an L-shaped cross section that exists in a stepped portion, wherein the tape-shaped paving material is applied from a paving material roll. By unrolling and pressing the upper side portion against the upper corner portion of the construction surface, the upper side portion of the tape-shaped paving material is sequentially applied to or near the upper corner portion of the construction surface having an L-shaped cross section.

As seen in FIG. 7, the second support mechanism 12 includes a support portion 21 that supports the side pressure roller 11 so as to be rotatable about the axis 11c, and a support arm connected to the support portion 21 via a screw portion 22p. 22, a support post 23 attached to one of the small slots _hS of the first frame 2 with a nut 23n, and a connecting pin 24 for rotatably connecting the support post 23 and the support arm 22. . By such a second support mechanism 12, the side pressing roller 11 is rotatably supported in a direction tilted from the horizontal with its tip facing downward. It is preferable that at least the outer peripheral portion of the side pressing roller 11 is made of an elastic material such as soft resin or rubber.

In this example, the second support mechanism 12 further includes an engaging post 25 attached to another small elongated hole _hS of the first frame 2 with a nut 25n, and an engaging post 25 and a threaded portion 22p of the support arm 22. and an elastic member 26 such as a coil spring stretched between the side pressing rollers 11 so that the side pressing rollers 11 are always pulled in the direction of the engagement posts 25, and are oriented downward in terms of direction. urged toward. In other words, the elastic member 26 such as a coil spring stretched between the engaging post 25 and the screw portion 22p of the support arm 22 serves as a biasing means for biasing the side pressing roller 11 downward. .

Since the second support mechanism 12 is provided with the biasing means as described above, the side pressing roller 11 is always biased and pressed against the upper corner _SE of the construction surface S during use. Therefore, the side portion of the tape-shaped pavement material can be better pressed and adhered to the upper corner SE of the construction surface _S or its vicinity.

Note that the biasing means is not limited to the coil spring. Of course, instead of the coil spring, a plate spring, rubber, or other elastic means may be used, and the arrangement of these elastic means is not limited to that shown in the drawings.

In this example, the support arm 22 and the support portion 21 are arranged such that the screw portion 22p formed at the lower end portion of the support arm 22 is screwed into the female screw portion formed inside the upper end portion of the support portion 21. By rotating the supporting portion 21 and the supporting arm 22 relative to each other, the supporting portion 21 is moved relative to the supporting arm 22 in its axial direction, and the height of the side pressing roller 11 is changed. Direction position can be adjusted. This makes it possible to always adjust the height direction position of the side pressing roller 11 to an optimum position even in a construction site where the height of the rising surface SS of the construction surface _S varies.

Further, by loosening the nuts 23n and 25n, the connection between the support column 23 and the engagement column 25 and the first frame 2 is temporarily released, and the support column 23 and/or the engagement column 25 are moved into the small elongated holes _hS . It is also possible to move to an appropriate position along the longitudinal direction at any time. As a result, the position of the side pressing roller 11 along the traveling direction of the side pressing device 1 of the tape-shaped pavement material is changed, and the distance between the side pressing roller 11 and the roll support 7, especially its roll support shaft 7r, is increased. can be changed and adjusted as appropriate. In order to fix the support column 23 and the engagement column 25 to the first frame 2, the nuts 23n and 25n should be tightened again.

8 is a left side view of FIG. 7. FIG. As shown in FIG. 8, a notch H is provided in a part of the side surface of the first frame 2, and the side pressing roller 11 passes through the notch H and passes through the upper corner of the working surface S. SE can _abut .

FIG. 9 is a reference plan view for explaining the positional relationship between the roll support shaft 7r and the side pressure roller 11 in the roll support 7. As shown in FIG. In FIG. 9, P7 is a vertical plane including the axis _7c of the roll support shaft 7r, P11 is a vertical plane including the axis 11c of the side pressure roller ₁₁ , and the vertical plane _P11 and the vertical plane _P7 is parallel to In other words, the side pressing roller ₁₁ is arranged so that the vertical plane P11 including the axis 11c thereof is parallel to the vertical plane P7 including the axis 7c of the roll support shaft 7r that constitutes the roll support ₇ . It is supported by the support mechanism 12 . In this way, since the axis 7c of the roll support shaft 7r and the axis 11c of the side pressure roller 11 are positioned on the vertical plane parallel to each other, the tape-shaped pavement unrolled from the roll support shaft 7r is formed. The material is brought into contact with the side pressing roller 11 without being twisted in any way, and is pressed and adhered to the upper corner SE of the work surface _S or its vicinity. .

FIG. 10, like FIG. 9, is a reference front view for explaining the positional relationship between the roll support shaft 7r and the side pressure roller 11 in the roll supporter 7, showing only the parts necessary for the explanation for convenience. There is. In FIG. 10, R is a pavement material roll, and the roll support shaft 7r is passed through the center gap of the pavement material roll R. It is supported by support 7 . W is the width of the tape-shaped paving material constituting the paving material roll R, and PR is a plane including the upper end side surface of the paving material roll _R in the above state. In other words, the plane PR is a roll end plane parallel to the contact surface 7s and separated from the contact surface 7s by a distance corresponding to the width W of the pavement material roll _R.

_C7C is a horizontal line drawn horizontally from the position where the axis 7c of the roll support shaft _7r intersects the roll end plane _{PR .} It is a horizontal line drawn horizontally from the position where it intersects with h _7C is the height from the reference plane of the horizontal line _{C 7C} (lower surface SL of the construction surface S in the illustration), h _11C is the height from the reference plane of the horizontal line _{C 11C} (lower surface SL of the construction surface S in the illustration) is the height of As is clear from the figure, there is a relationship of h _7C >h _11C , and the axis 11c of the side pressing roller 11 intersects the roll end plane PR, and the intersecting position is the axis of the roll support shaft _7r . The core 7c is supported by the second support mechanism 12 so as to be below the position where it intersects the roll end plane _PR . As is clear from the drawing, the pressing roller surface of the side pressing roller 11 extends on both sides of the roll end plane _PR .

In this way, the side pressing roller 11 has its axis 11c intersecting the roll end plane _PR , and the intersection position is located from the position where the axis 7c of the roll support shaft _7r intersects the roll end plane PR. The side pressure rollers 11 are supported by the second support mechanism 12 at positions where the pressure roller surfaces of the side pressure rollers 11 extend on both sides of the roll end plane _PR . As a result, the tape-shaped pavement material fed out from the pavement material roll R is smoothly pressed and adhered to the upper corner SE of the construction surface S. As shown in _FIG .

As can be seen in FIGS. 12 and 13, the first pressing ring 31 is composed of two thin truncated cone-shaped lower half rings 31a and upper half rings 31b of the same shape, which are pasted together with their bottom surfaces aligned with each other. It is rotatably supported around a support shaft 31r that passes through the center of both bottom surfaces and is perpendicular to both bottom surfaces.

A side surface 31as of the two truncated cone-shaped lower half rings 31a and a side surface 31bs of the upper half ring 31b constitute the outer peripheral end surface of the first pressing ring 31. As shown in FIG. 31t is the vertex of the outer peripheral end face. As shown in the figure, the outer peripheral end surface of the first pressing ring 31 constituted by the side surfaces 31as and 31bs protrudes radially over the entire circumference of the first pressing ring 31, and the protrusion angle α1 is _less than 90 degrees, i.e. sharp angle.

Further, the angle _β1 formed between the plane P1 including the vertex _31t of the outer peripheral end face and the horizontal plane is 45 degrees. Although the angle _β1 is not necessarily limited to 45 degrees, considering that the angle of the internal corner S _C on the construction surface S with an L-shaped cross section is usually 90 degrees, the tape-shaped pavement material is the first It is _most preferable that the angle β1 is 45 degrees or approximately 45 degrees in order to reliably press even the inside corner S _C with the pressing ring 31, and even if it deviates slightly, it is within the range of 40 degrees to 50 degrees. is preferred.

14 is a front view of FIG. 11, and FIG. 15 is a view of only the second pressing ring 32 shown in FIG. In FIG. 14, the first pressing ring 31 is not drawn for convenience.

As seen in FIGS. 14 and 15, the second pressing ring 32 is composed of two truncated cone-shaped lower half rings 32a and upper half rings 32b having the same bottom radius and different heights. The ring 32a and the upper half ring 32b are combined so that the centers of their bottom surfaces are aligned and the bottom surfaces contact each other. The lower half ring 32a and the upper half ring 32b are rotatably supported by a support shaft 32r passing through the center of each bottom surface and perpendicular to the bottom surface. Since the lower half-wheel 32a and the upper half-wheel 32b are not connected, they can rotate independently about the support shaft 32r.

A frustoconical side surface 32as of the lower half ring 32a and a frustoconical side surface 32bs of the upper half ring 32b form an outer peripheral end face of the second pressing ring 32. As shown in FIG. 32t is the vertex of the outer peripheral end face. As shown in the figure, in this example, the angle α ₂ formed between the bottom surface of the truncated cone of the lower half ring 32a and the side surface 32as, and the angle α ₃ formed between the bottom surface of the truncated cone of the upper half ring 32b and the side surface 32bs. are both 45 degrees, and the angle obtained by adding α2 and α3 _, that is, the angle at which the outer peripheral end surface of the _second pressing ring 32 protrudes radially over the entire outer periphery of the second pressing ring 32 is 90 degrees. It has become.

As described above, the angle of the internal corner SC in the construction surface _S having an L-shaped cross section is usually 90 degrees. , the second pressing ring 32 reliably contacts both the side surface 32bs of the lower half ring 32a and the side surface _32bs of the upper half ring 32b with the lower surface SL and the rising surface SS of the construction surface _S , respectively. It can move along the internal corner _SC of S.

The angle β2 formed by the plane P2 including the vertex _32t of the outer peripheral end face with the horizontal plane is the same as the angle α2 formed between the bottom surface of the lower _half ring 32a and the side surface _32as , which is 45 degrees in this example. Although the angle β2 is not necessarily limited to 45 degrees, the plane P2 including the vertex _32t of the outer peripheral end face of the _second pressing ring 32 and the vertex of the outer peripheral end face of the first pressing ring 31 shown in FIG. The plane P ₁ containing 31t is preferably on the same plane, preferably β ₁ =β ₂ .

The second pressing wheel 32 is made of any material as long as the tape-shaped pavement material can be pressed and adhered to both the lower surface SL and the rising surface SS of the construction surface _S having an _L -shaped cross section. For example, it can be constructed using an appropriate material such as rubber, synthetic resin, or metal. However, considering that the construction surface S usually has some unevenness, at least the surface of the second pressing ring 32 is made of elastic natural or artificial rubber such as urethane rubber. It is desirable to be

C. Method of Pressing and Adhering Pavement Material Hereinafter, a method of pressurizing and adhering a tape-shaped pavement material using the side pressing device 1 and the tape surface pressing device 30 described above will be described with reference to FIGS. 16 to 20. to explain. 16 to 20, members not directly involved in the explanation are omitted.

First, as shown in FIG. 16, the pavement material roll R is set at a predetermined position on the roll support 7 of the side pressing device 1 . The pavement material roll R is supported on the roll support 7 with the roll support shaft 7r passing through the center gap and the lower side surface being in contact with the contact surface 7s. At this time, on the upper side surface of the pavement material roll R supported on the roll support 7, a disk-shaped stabilizer having a gap at the center for allowing the roll support shaft 7r to pass through is placed, The support of the pavement material roll R by the roll support 7 may be stabilized. In the state shown in FIG. 16, the side pressing device 1 is at a predetermined pressing position where the side surfaces of the guide rollers 13a and 13b (not shown in FIG. 16) are in contact with the rising surfaces SS of the working surface _S , The side pressing surface of the side pressing roller 11 is urged downward by an elastic member 26 such as a coil spring, and is in contact with the upper corner SE of the working surface S. As shown in _FIG .

Next, the tip of the tape-shaped paving material T exposed to the outermost layer of the paving material roll R is gripped, and as shown in FIG. The tape-shaped paving material T is inserted into the lower side of the roller 11 so that the upper side portion Ts of the paving material T is sandwiched between the upper corner SE of the construction surface _S and the side pressing roller 11. to set. After that, in this state, the side pressing device 1 can be moved in the depth direction of the paper surface.

FIG. 18 is a plan view showing a state in which the side pressing device 1 has been moved from the state shown in FIG. 17 to the depth direction of the plane of FIG. As shown in FIG. 18, when the side pressing device 1 is moved in the direction of the arrow in the figure, the upper side portion Ts of the tape-shaped pavement material T is pushed along with the side pressing roller 11 and the upper corner portion of the construction surface S. Since the pavement material roll R is successively sandwiched between SE and _E and pressed, it rotates around the roll support shaft 7r in the direction indicated by the arrow in the figure. At this time, since the vertical plane including the axis 7c of the roll support shaft 7r for supporting the pavement material roll R and the vertical plane including the axis 11c of the side pressure roller 11 are in a parallel positional relationship, the tape The shaped pavement material T is successively fed out from the roll R without being twisted. As a result, the upper side portion Ts of the tape-shaped pavement material T is pressed and adhered to the upper corner portion SE of the construction surface _S or its vicinity. This corresponds to the tape side portion pressing step in the pressure-adhering method of the present invention.

When the tape side portion pressing step is completed, next, the tape surface pressing device 30 is placed on the construction surface S on which the upper side portion Ts of the pavement material T is pressed and adhered to the upper corner portion _SE or its vicinity. The first pressing ring 31 is advanced in the direction of the first. FIG. 19 shows this state. That is, as shown in _FIG . 19, when the first pressing wheel 31 is advanced over the construction surface where the upper side portion Ts of the paving material T is pressed and adhered to the upper corner SE of the construction surface S, paving is performed. At a position between the upper and lower sides of the material T, the material T is pushed by a first pressing ring 31 whose outer peripheral end surface protrudes at an acute angle, and is successively _pressed toward the inside corner SC of the working surface S. It will be in close _contact with SC. This corresponds to the first pressing step in the pressure bonding method of the present invention.

Subsequently, the second pressing wheel 32 of the tape surface pressing device 30 is placed on the construction surface S where the pavement material T is pressed toward the inside corner SC of the construction surface _S at a position between the upper and lower sides thereof. proceed. FIG. 20 shows this state. That is, as shown in _FIG . 20, the tape-shaped pavement material T is pressed and adhered to the upper corner SE of the construction surface S with its upper side portion Ts, and is inserted at a position between its upper and lower side portions. When the second pressing wheel 32 is advanced on the construction surface _S pressed toward the corner SC, the portion of the construction surface _S of the pavement material T facing the rising surface SS is the second pressing wheel 32. The upper half ring 32b presses and adheres to the rising surface SS, and the surface facing the lower surface _SL of the construction surface _S of the pavement material T is pressed against the lower surface SL by the lower half ring _32a of the second pressing ring 32. , will be affixed. This corresponds to the second pressing step in the pressure bonding method of the present invention.

At this time, since the upper half ring 32b and the lower half ring 32a can rotate independently around the support shaft, even if the construction surface S has some unevenness or unevenness, the tape can be The pavement material T having a shape can be pressed and adhered to the construction surface S having an L-shaped cross section with little displacement.

As described above, according to the pressure-adhering method of the present invention, the upper side portion of the tape-shaped pavement material T is first pressure-adhered to the upper corner SE of the construction surface _S or its vicinity, and then , the part of the construction surface S of the paving material T facing the internal corner S _C is pressed toward the internal corner S _C , and then the rising surface S _S and the lower surface S _L of the construction surface S of the paving material T are pressed. Since the tapered portions are pressed and adhered to the rising surface SS and the lower surface SL, respectively, the tape-shaped pavement material T can be pressed and adhered to the construction surface _S having an _L -shaped cross section without shifting. is possible.

In the above example, the tape surface pressing device 30 for the tape-shaped paving material is connected to the second frame in which the first pressing wheel 31 and the second pressing wheel 32 are connected to the common second frame. Although the case where they are integrated has been described, the first pressing ring 31 and the second pressing ring 32 do not necessarily need to be integrated. That is, the tape surface pressing device 30 for the tape-shaped pavement material may be composed of the first pressing wheel 31 and the second pressing wheel 32 which are separately present.

According to the pressure-adhering apparatus and the pressure-adhering method according to the present invention, the tape-shaped pavement material is efficiently pressed and adhered to the work surface having an L-shaped cross section without the worker bending down. Therefore, it greatly contributes to work efficiency and labor reduction, and has great industrial applicability.
