Description

  The present invention relates to a pavement material pressing and sticking apparatus, and more specifically, a pavement material pressing and sticking that presses and sticks a tape-like pavement material wound in a roll shape onto a construction surface having a horizontal surface and a rising surface. Relates to the device.

  Conventionally, in order to prevent the intrusion of rainwater from the joint part and pavement edge of asphalt pavement, a molded joint material formed in a tape shape has been used. Various devices for attaching to the surface have been proposed as seen in Patent Documents 1 and 2, for example.

  However, the molding joint material targeted by these conventional sticking machines is a tape-shaped joint material having a substantially constant cross-sectional shape, and this is used for, for example, asphalt pavement joints and pavement end parts to prevent rainwater from entering. Even if you try to attach it to the vertical surface at the joint between the curb and the curb, etc., the vertical cross section of the joint part usually has irregularities and dust, so it sticks once, but it will immediately come from the upper end part and There was a drawback that it was difficult to ensure close contact.

  In order to solve such drawbacks, the present applicant has developed a molding joint material formed into a tape shape having a dent for folding along an assumed folding line on one side or both sides. Disclosed. Since this molding joint material has a dent for bending, it can be easily folded into an L shape and adhered and adhered to both the horizontal surface and the rising surface of the pavement joint portion and the L-shaped section. It is a very excellent molded joint material that can effectively prevent the penetration of rainwater from the joint and paved edges.

  However, as far as the present applicant knows, an apparatus for sticking a molding joint material having a dent for bending as disclosed in Patent Document 3 to both a horizontal surface and a rising surface of an L-shaped construction surface is still proposed. In actual construction, the worker is bending and molding the joint material, and manually pressing and sticking the bent corner to the corner of the L-shaped construction surface. is there. However, such work takes a lot of time and work in a bent state, which is extremely hard work for an operator.

  The pressing and adhering wheel may be composed of any material as long as it can press and stick the tape-shaped paving material to both the horizontal surface and the rising surface, such as rubber, synthetic resin, metal, etc. However, considering that the construction surface of the L-shaped section usually has some irregularities, at least the surface thereof is made of natural or artificial rubber having elasticity. It is desirable to be configured. In addition, the pressing and adhering ring is made of a plate member such as a steel plate, a metal plate such as an aluminum plate, or a hard plastic plate, and two conical trapezoidal members having a hollow inside are joined together at the bottom and a rubber sheet is attached to the surface. A rubber layer may be formed by means such as affixing, and if configured in this way, a pressure adhering ring having a shape in which two truncated cones are joined can be manufactured with high dimensional accuracy and at low cost. Can do.

  The pavement material pressing and sticking apparatus according to the present invention is a front wheel that rotates around a second rotation shaft located on a vertical plane parallel to the first rotation shaft of the pressing and bonding wheel, in addition to the pressing and bonding wheel. And at least one side wheel that rotates around a horizontal third rotation axis that is located on a vertical plane parallel to the first rotation axis. The said side wheel is arrange | positioned so that the said plane may be located in the side in which the said plane inclines with respect to the plane containing the joining surface of the said two truncated cones which comprise the external shape of a press sticking wheel. That is, when the front wheel is the front and the pressure sticking wheel is the rear, the plane including the joining surface of the two truncated cones constituting the pressure sticking wheel is on the right side with respect to the line connecting the front wheel and the pressure sticking wheel. The side wheel is positioned on the right side when tilted, and on the left side when tilted on the left side. When the number of side wheels is one, the center of gravity of the entire device is positioned at or near the center of the triangle formed by the front wheel, the pressure adhering wheel, and the side wheels, and when there are two or more side wheels, By positioning the center of gravity of the entire apparatus at or near the center of a quadrilateral or more polygon made up of the pressing and adhering wheels and the side wheels, the paving material pressing and adhering apparatus according to the present invention is extremely stable. It can be made to advance along the corner of the construction surface having an L-shaped cross section.

Since it progresses along a corner, it becomes possible to more reliably perform pressing and sticking of the paving material.

Wherein two of the truncated cone, on the opposite side of the angle alpha ₁ and the bonding surface of the first truncated cone between the first truncated cone of the bottom and side surfaces positioned on the side where the joint surface is inclined the sum of the angle alpha ₂ between the second frustoconical bottom and sides to position corresponds to the angle of the corner portion formed on the intersection of the two truncated cone side surfaces form the outer shape of the pressing lamination Chakuwa To do. Therefore, by setting the angle of the corner of the L-shaped construction surface for the sum of α ₁ and α ₂ to coincide with the angle of the corner of the corner, the angle of the corner of the corner is approximately 90 degrees and is substantially perpendicular to the horizontal plane. In addition to an L-shaped construction surface having a rising surface that rises at the same angle, an L-shaped construction surface having a rising surface that rises at an acute angle from a horizontal surface with an angle of entry of less than 90 degrees is also used. Is applied to the pavement material pressing and pasting device of the present invention also on an L-shaped construction surface having a rising surface that rises at an obtuse angle from the horizontal plane, and the corner of the pressing and pasting wheel is inserted into the corner. It is possible to press and stick the tape-shaped paving material accurately by making the two side surfaces of the pressing and adhering wheel abut both the horizontal and rising surfaces. Note that α ₁ and α ₂ may be the same or different.

As a result, the paving material molded in a tape shape is pressed and pasted with a wide difference on the horizontal surface side of the construction surface having an L-shaped cross section, a narrow width on the rising surface side, and a wide or narrow difference in the pasting width. Sometimes preferred. On the other hand, when h ₁ <h ₂ , the width of the side surface of the truncated cone located on the upper side is the width of the side surface of the truncated cone located on the upper side of the two truncated cones constituting the pressure adhering ring. Pressing pavement material molded in a tape shape with a narrow width on the horizontal plane side of the construction surface with an L-shaped cross section, a wide width on the rising surface side, and a wide width on the sticking width. It is suitable when sticking. Further, when h ₁ = h ₂ , the width of the side surface of the truncated cone located on the lower side is the same as the width of the side surface of the truncated cone located on the upper side. This is suitable when the material is pressed and pasted with the same width on both the horizontal surface and the rising surface of the L-shaped construction surface.

  Moreover, the pavement material press sticking apparatus of this invention WHEREIN: The other preferable one aspect | mode WHEREIN: The said pavement material holding | maintenance part is parallel to the plane containing the joint surface of the two truncated cones which comprise the said press sticking ring | wheel. A connecting support plate and a roll holding shaft that is rotatable about its own rotation axis. The connection support plate has a vertically long hole that passes through the connecting support plate, and the roll holding shaft rotates. An attachment member for attaching one end of the shaft perpendicularly to the connection support plate and having a variable attachment position with respect to the elongated hole with the elongated hole penetrating the elongated hole. When the pavement material pressing and sticking apparatus of the present invention includes the connection support plate and the roll holding shaft, of course, when the pavement material wound in a roll shape is substantially cylindrical, a roll The roll holding shaft is inserted into the center hole of the paving material, and the roll holding shaft is inserted through the elongated hole even though it is wound into a shape but is deformed into an irregular shape. By attaching to the connecting support plate, the paving material holding part can smoothly hold the paving material wound in a roll shape so as to be freely rotatable. The material can be delivered stably and smoothly. A paving material retaining member whose center hole is inserted into the roll holding shaft may be attached to the other end of the roll holding shaft opposite to the side inserted into the long hole. .

  The pavement material pressing and sticking apparatus according to the present invention is, in another preferred embodiment, a tape-like pavement material in which the pavement material holding portion is fed from the roll in the vicinity of the pavement material delivery port. The guide member which contact | abuts the lower side part is provided. When the pavement material pressing and sticking apparatus of the present invention includes the guide member, it effectively prevents the tape-shaped pavement material after being fed from the roll from being displaced obliquely downward due to gravity. Thus, a tape-shaped paving material can be supplied between the pressure adhering wheel and the construction surface.

  Moreover, the pavement material pressing and sticking device according to the present invention is, in another preferred embodiment, a tape-like shape in which the lower end of the guide member is located lower than the lower end of the guide member and wound in the form of a roll. A guide member protection member that rolls or slides on the construction surface when the pavement material is pressed and pasted to prevent the guide member from contacting the construction surface. . When the pavement material pressing and sticking apparatus of the present invention includes the guide member protection member, the guide member is located below the lower end of the guide member even if the horizontal construction surface is uneven. Since the protective member first comes into contact with the convex portion of the construction surface and lifts the entire pavement material pressing and sticking apparatus of the present invention, the lower end of the guide member is prevented from coming into contact with the convex portion, and the guide The deformation and damage of the member can be prevented. Moreover, when the said guide member protection member contacts the unevenness | corrugation of a construction surface, since it rolls or slides on a construction surface itself, the smooth driving | running | working of the material press sticking apparatus for pavement is not prevented. As the guide member protection member, for example, a ball whose lower end protrudes from the housing while being rotatably held in the housing so as not to drop out of the housing, or a frame that can rotate 360 ° around the vertical axis. A wheel that can rotate around a horizontal axis that is held, or at least its lower end surface is made of a metal such as copper, aluminum, or an alloy thereof, a synthetic resin such as polyacetal or polytetrafluoroethylene, or a low friction coefficient such as carbon. A member formed or coated with a material having good mobility can be used.

  The pavement material pressing and sticking device of the present invention, in another preferred embodiment thereof, further comprises a bent contact piece disposed between the pavement material delivery port and the pressing and sticking wheel. The linear lower end portion is located on a plane including the joint surface of the two truncated cones constituting the press adhering wheel, and is used for paving from the material for paving to the press adhering wheel. A bending contact piece in linear contact with the upper surface of the material; two flat surfaces intersecting in a V-shaped cross section, the intersection line being on a plane including the joining surface, and the bending contact A bending auxiliary member disposed on two planes located below the lower end of the contact piece, the pavement material heading from the pavement material delivery port to the press sticking wheel A bending assisting member that contacts the lower surface and both sides of the lower end portion is provided.

  When the pavement material pressing and sticking apparatus includes the bending contact piece and the bending auxiliary member, the tape-like pavement material sent out from the pavement material delivery port is the bending contact piece. The tape is paved while the upper surface thereof is in linear contact with the bending contact piece while being supplied between the pressing and adhering wheel and the construction surface through the bending assisting member. The material is pushed down along the assumed fold line of the material, and the lower surface of the material is in contact with the bending assisting member on both sides of the lower end of the bending assisting member, and both sides of the tape-shaped paving material are , Pushed upward along the assumed fold line. As a result, the tape-shaped paving material fed out from the paving material delivery port matched the shape of the construction surface with the L-shaped cross section along the assumed fold line until it reached the press sticking wheel. It is bent into a cross-sectional shape, and is smoothly pressed and stuck at the corner of the construction surface by the pressure sticking wheel.

  Further, when the distance between the lower end portion of the bent contact piece and the intersecting line is gradually shortened from the pavement material delivery port toward the pressing and pasting wheel, the pavement is gradually and gradually reduced. The material can be transformed into a cross-sectional shape that matches the shape of the construction surface having an L-shaped cross section.

  In another aspect of the pavement material pressing and sticking device of the present invention, the pressing and sticking wheel is fixed so as not to rotate with respect to the first rotation shaft. That is, depending on the material constituting the press-bonding wheel, for example, when the tape-shaped paving material has a release sheet on the contact surface with the press-bonding wheel, the press-bonding wheel is paved. When it is possible to move while sliding on the working material, the pressing and adhering wheel does not necessarily rotate itself, and may be fixed so as not to rotate with respect to the first rotation shaft. .

  By the way, when the press sticking wheel is fixed with respect to the first rotation axis and does not rotate, the press sticking wheel joins the two truncated cones having the same bottom radius to each other with the bottom surfaces being aligned with each other. It is not necessary to have all of the outer shapes. The pressing and adhering wheel has at least the first rotation among the vertical surfaces including the first rotation axis, out of the outer shapes in which two truncated cones having the same bottom radius are joined at the bottoms with their bottom centers aligned. A portion that is surrounded by a lower side than the axis and a plane that includes the first rotation axis and that is orthogonal to the vertical plane, and that is surrounded by the front side in the traveling direction relative to the first rotation axis, and includes the first rotation axis. A vertical plane including the outer shape of a portion whose center angle is 90 degrees or less, preferably 45 degrees or more and 90 degrees or less, and the side surfaces of the two truncated cones and the first rotation axis, starting from a plane. It is only necessary to have an outer shape having two flat portions extending in a direction tangential to the bottom surfaces of the two truncated cones from the line of intersection with each other. The tape-shaped paving material is first brought into contact with the portion having the central angle of 90 degrees or less, and then sandwiched between the two plane portions extending in the tangential direction of the bottom surfaces of the two truncated cones and the construction surface. Then, the pressing and adhering wheel moves while sliding on it, and is pressed and adhered to both the horizontal surface and the rising surface of the L-shaped construction surface.

  Furthermore, in another preferable aspect of the pavement material pressing and sticking device of the present invention, a main body that integrally connects the pressing and sticking wheel, the front wheel, the side wheel, and the pavement material holding unit. It is composed of two or more parts that are pivotably connected to each other around a vertical axis. When the main body is composed of two or more parts that are pivotably connected to each other around a vertical axis, the main body can be bent. Even for a construction surface that is curved in a horizontal plane, the pavement material pressing and sticking device of the present invention can be advanced with its front wheels and pressing and sticking wheels following the corners of the construction surface well. The tape-shaped paving material can be pressed and adhered to the curved construction surface.

  The tape-shaped pavement material targeted by the pavement material pressing and sticking apparatus of the present invention is most preferably a molded joint material having a dent for folding disclosed in Patent Document 3, but is not limited thereto. It is not a thing, but is a tape-shaped paving material wound in a roll shape, and any paving material that is pressed and stuck to both the horizontal surface and the rising surface of the L-shaped construction surface Such a paving material may be used. In addition, there is no particular limitation on the L-shaped construction surface targeted by the pavement material pressing and sticking device of the present invention, and the rise of pavement joints, curbs, paving stops, bridge end structures, etc. Of course, a construction surface having a substantially L-shaped cross section created by cutting and removing a part of an existing pavement as well as a part is naturally included.

  According to the pavement material pressing and sticking apparatus of the present invention, the tape-like pavement material wound in a roll shape is set on the pavement material holding portion of the main body of the apparatus, and one end thereof is fed out from the roll and pressed and stuck. In the state inserted between the wheel and the construction surface, the pavement material pressing and sticking device of the present invention is advanced in the front wheel direction to fold the tape-like pavement material, It can be pressed and adhered to both the horizontal and rising surfaces. According to the present invention, the worker is released from the work in a bent state, and performs the work of pressing and sticking the tape-shaped paving material to the construction surface having an L-shaped cross section efficiently and quickly. The excellent advantage of being able to do so is obtained. In addition, the tape-shaped paving material that has been pressed and adhered is in close contact with both the horizontal surface and the rising surface, so that the upper end does not sway and is difficult to peel off from the construction surface. When is a molded joint material, there is an advantage that it is excellent in water-stopping effect at the joint part, effectively prevents rainwater and the like from entering, and can increase the durability of the pavement structure.

However, considering that the construction surface having an L-shaped cross section usually has some irregularities, the pressure adhering wheel 2 is a natural or artificial rubber whose surface is elastic at least, such as urethane rubber. It is desirable to be composed of.

  5 is a plan view of the pavement material pressing and sticking apparatus 1 shown in FIG. 1, and FIG. 6 is a front view of the pavement material pressing and sticking apparatus 1 shown in FIG. In FIG. 5 and FIG. 6, only the pressure adhering wheel 2, the front wheel 3, and the side wheel 4 are extracted and shown.

5 and FIG. 6, _{R 1} is first rotating shaft. The first rotation axis R ₁ is perpendicular to the bottom surface as the center c ₁ and c ₂ of the bottom surface of the truncated cone 2 ₁ and a truncated cone 2 ₂ constituting the outer shape of the pressing lamination Chakuwa 2, pressing bonded Chakuwa 2 It is rotatably supported to the first about an axis of rotation R _1. R ₂ is a second rotating shaft on which the front wheel 3 is rotatably supported. R ₃ is a _third rotating shaft on which the side wheel 4 is rotatably supported.

As shown in FIGS. 5 and 6, the first rotation axis R ₁ and the second rotation axis R ₂ are parallel to each other, both are inclined from the horizontal by an angle beta. Further, as shown in FIG. 6, the front wheel 3, the center 3c in the width direction, pressing adhered truncated cone constituting the outer shape of Chakuwa 2 2 ₁ and frustoconical 2 on the plane P including the _second joining surface of the bottom between It arrange | positions with respect to the press sticking wheel 2 so that it may be located in.

Incidentally, FIG. 5, the second rotation axis R ₂ illustrated in FIG. 6 is merely an example, the inclination angle of the second horizontal axis of rotation R ₂ are not necessarily, the slope of the first horizontal axis of rotation R ₁ It does not have to be the same as the angle β. That is, the front wheel 3, during the course of paving material pressing attaching apparatus 1, it suffices that the support at least a portion of the load of paving material pressing attaching apparatus 1, from the horizontal with the second rotation axis R ₂ The inclination angle can be set to an appropriate angle in the range of 0 ° to less than 90 °. Furthermore, in the examples of FIGS. 5 and 6, the second rotation axis R ₂ that is the rotation axis of the front wheel 3 is inclined to the same side as the first rotation axis R ₁ that is the rotation axis of the press-bonding wheel 2. the second rotation axis R ₂ may be good inclined to the first rotation axis R ₁ on the opposite side. In any case, the second rotation axis R ₂ may if not vertical, but may be a proper inclination angle in a range of less than 0 ° or 90 ° with respect to the horizontal plane, paving material pressing sticking device 1 During the process, the load of the pavement material pressing and sticking apparatus 1 is moderately shared, and the pavement material pressing and sticking apparatus 1 is smoothly advanced along the construction surface having an L-shaped cross section. The inclination angle of R _{2 from} the horizontal is preferably 0 °, or preferably the same as the inclination angle β of the first rotation axis R _{1 from} the horizontal.

  Moreover, there is no special restriction | limiting in the material which comprises the front wheel 3, and the front wheel 3 may be comprised with what kind of material, as long as it can advance along the corner of the construction surface of L-shaped cross section. . The front wheel 3 can be configured by using an appropriate material such as rubber, synthetic resin, metal, etc., but it is considered that the construction surface having an L-shaped cross section usually has some unevenness. Then, it is desirable that at least the surface thereof is made of a natural or artificial rubber having elasticity, such as urethane rubber, as in the case of the press-bonding wheel 2.

On the other hand, the side wheel 4, as shown in FIGS. 5 and 6, with respect to a plane P including the bonding surface of the bottom ends of the truncated cone 2 ₁ and a truncated cone 2 ₂ constituting the outer shape of the pressing lamination Chakuwa 2, the plane P Is located on the inclined side. In FIG. 6, since the plane P is inclined to the left in the figure, the side wheel 4 is arranged on the left side with respect to the plane P, but when the plane P is inclined to the right in FIG. The side wheel 4 is arranged on the right side with respect to the plane P. In addition, the third rotation axis R ₃ on which the side wheel 4 is rotatably supported is located between the first rotation axis R ₁ and the second rotation axis R _2, and the first rotation axis R ₁ It is located on a parallel vertical plane Q and is horizontal.

  As described above, in the pavement material pressing and sticking device 1 of this example, the pressing and sticking wheel 2, the front wheel 3, and the side wheels 4 are arranged so as to form a triangle, and the pavement material pressing and sticking device 1. Since all members are arranged so that the position of the center of gravity on the horizontal plane B is substantially at the center of the triangle, the pavement material pressing and sticking apparatus 1 is extremely stable. In this example, only one side wheel 4 is provided, but if necessary, two or more side wheels 4 may be arranged on the side where the plane P is inclined. Even in that case, the position of the center of gravity of the pavement material pressing and sticking device 1 on the horizontal plane B is a quadrangular or pentagonal or more polygon formed by the pressing and sticking wheel 2, the front wheel 3, and the side wheel 4. Of course, other members are arranged so as to be substantially at the center.

In the examples shown in FIGS. 5 and 6, the third rotation axis R ₃ is disposed between the first rotation axis R ₁ and the second rotation axis R ₂ , but the third rotation axis R ₃ As long as the paving material pressing and sticking device 1 can be stably supported by the pressing and sticking wheel 2, the front wheel 3, and the side wheel 4, the first rotating shaft R ₁ and the second rotating shaft R ₂ are not necessarily used. For example, depending on the position of the center of gravity of the pavement material pressing and sticking device 1 on the horizontal plane B, for example, on the same plane as the first rotation axis R ₁ or the second rotation axis R ₂ may be on the same plane. Furthermore, the position of the center of gravity of the pavement material pressing and sticking device 1 on the horizontal plane B can be stored in a polygon connecting the pressing and sticking wheel 2, the front wheel 3 and the side wheel 4. In the case where the landing apparatus 1 can stably stand on its own, the third rotating shaft R ₃ is disposed on the rear side in the moving direction with respect to the first rotating shaft R ₁ or on the front side in the moving direction with respect to the second rotating shaft R _2. Also good. For example, two side wheels 4 are provided, the third rotation axis R ₃ of one side wheel 4 is arranged behind the first rotation axis R _{1 in the} advancing direction, and the rotation axis R ₃ of the other side wheel 4 is 2 may be arranged forward in the traveling direction side of the rotational axis R _2. The side wheel 4 rotating around the third rotation axis R ₃ can rotate on the horizontal plane along the corner of the construction surface while receiving a part of the load of the pavement material pressing and sticking device 1. Is possible.

  The material constituting the side wheel 4 is not particularly limited, and the side wheel 4 may be made of any material as long as it can proceed on the construction surface. For example, rubber, synthetic resin, It is configured using an appropriate material such as metal.

Figure 7 is a I-I cutting plane of FIG. 2, connecting the state where the paving material pressing sticking device 1 taken along a plane P including the two frustoconical 2 ₁ and the bonding surface of the truncated cone 2 ₂ It is the figure seen from the support plate 6 side. For convenience, reference numerals 8a, 8b, 8c,..., 8h are assigned to the plurality of rotating rollers 8 in order from the front wheel 3 side. As shown in FIG. 7, the plurality of rotating rollers 8 a to 8 h that are rotatably mounted between the connection support plates 5 and 6 are located on the same arc centered on C, with the respective rotation centers being substantially equidistant. A plurality of rotating rollers 8a to 8h and a circular region γ surrounded by a broken line drawn on the connection support plate 5 by the plurality of rotating rollers 8a to 8h are wound in a roll shape. A paving material holding part 5h for holding the rotated tape-like paving material is configured. It is needless to say that the radius of the circular region γ is set to be larger than the assumed maximum radius of the pavement material roll held by the pavement material holding portion 5h. In addition, as shown in FIG. 7, the pavement material holding portion 5 h is located on the front wheel 3 side with respect to the press sticking wheel 2.

  In this example, the gap between the rotating roller 8e and the rotating roller 8f is a paving material delivery port 15 that feeds a tape-shaped paving material from the paving material holding part 5h toward the pressing and adhering wheel 2. ing. Reference numeral 16 denotes a guide member provided in the vicinity of the paving material delivery port 15, and reference numeral 10 denotes a guide roller as described above.

  FIG. 8 is a diagram showing a state in which the tape-shaped paving material T wound in a roll shape is held in the paving material holding portion 5h. As described above, the radius of the circular region γ is set larger than the assumed maximum radius of the roll of paving material to be held by the paving material holding portion 5h. The roll of the material T falls within the region γ, and comes into contact with any one of the rotating rollers 8a to 8h on the outermost surface of the roll. In this state, the end portion of the wound tape-shaped paving material T is peeled off from the roll, and the direction of the pressing and adhering wheel 2 from the paving material delivery port 15 which is the gap between the rotating roller 8e and the rotating roller 8f. When pulled out, the roll-shaped paving material T rotates counterclockwise as indicated by a large arrow in the figure. The surface of each rotating roller is made of a fluororesin such as polytetrafluoroethylene, or the surface of each rotating roller is provided with irregularities to reduce the contact area with the material for paving T, thereby paving material. It is possible to more reliably prevent T from sticking to the surfaces of the rotating rollers 8a to 8h. In addition, when the tape-shaped paving material T wound in a roll shape can smoothly slide and rotate on the surfaces of the plurality of rotating rollers 8a to 8h, the rotating rollers 8a to 8h are connected to each other in a pair. The support plates 5 and 6 may not be supported rotatably, and may be fixed.

  A guide roller 10 is provided in the vicinity of the paving material delivery port 15, and the tape-shaped paving material T fed from the paving material delivery port 15 contacts the guide roller 10, and its traveling direction is slightly downward. Pushed down. For this reason, the contact between the paving material T fed out from the paving material delivery port 15 and the rotating roller 8f rotating in the clockwise direction indicated by a small arrow in the drawing along with the rotation of the roll-shaped paving material T is prevented. The paving material T can be smoothly fed out from the paving material delivery port 15. Further, since the guide member 16 is provided in the vicinity of the paving material delivery port 15, the lower side portion of the tape-shaped paving material T delivered from the paving material delivery port 15 has a guide member 16 at its lower side. And the position is prevented from shifting obliquely downward due to gravity.

FIG. 9 is a rear view of the pavement material pressing and sticking apparatus 1 in the state shown in FIG. 8, that is, the tape-like pavement material T wound around the pavement material holding portion 5h. It is. As shown in FIG. 9, the distance between the pair of connection support plates 5 and 6 is set to be larger than the assumed maximum width of the pavement material roll to be held by the pavement material holding portion 5h. The wound tape-shaped paving material T is held between the pair of connection support plates 5 and 6 with the lower side surface of the roll being in contact with the circular region γ of the connection support plate 5. The Further, as shown in FIG. 9, the pressing plane P including the two joint surfaces of the truncated cone 2 ₁ and 2 ₂ bonded to form the outer shape of the Chakuwa 2, the tape-like paving material T wound into a roll It is located within the width of. In this state, the end portion of the wound tape-shaped paving material T is peeled off from the roll, and the direction of the pressing and adhering wheel 2 from the paving material delivery port 15 which is the gap between the rotating roller 8e and the rotating roller 8f. Then, as described above, the roll-shaped paving material T is pulled, and is perpendicular to the surface of the connection support plate 5 while being in contact with any one of the region γ of the connection support plate 5 and the rotation rollers 8a to 8h. Rotate around the axis. Since the support shaft 11 of the pressing and adhering wheel 2 is attached perpendicularly to the connection support plates 5 and 6, the first rotating shaft R on which the pressing and adhering wheel 2 is rotatably supported. ₁ and the rotation axis of the tape-shaped paving material T wound in a roll shape are parallel to each other.

  In this example, the pavement material holding portion 5h is composed of a region γ and a plurality of rotating rollers 8a to 8h. However, the pavement material holding portion 5h is a tape-like shape wound in a roll shape. The paving material T may be of any structure as long as it can be held so that the end of the paving material T can be pulled out in the direction of the pressing and adhering wheel 2 by peeling the end of the paving material T from the roll. For example, instead of the plurality of rotating rollers 8 a to 8 h, a roll holding shaft is vertically attached to the connection support plate 5, and the pavement material holding portion 5 h is configured by the roll holding shaft and the inner side surface of the connection support plate 5. You may do it. In this case, in order to hold the tape-shaped paving material T wound in a roll shape in the paving material holding portion 5h, for example, the connection support plate 6 is temporarily removed and the roll holding shaft is rolled. What is necessary is just to let the center hole of the wound tape-shaped paving material T penetrate. Further, in this case, a pair of guide rolls are provided at appropriate positions between the pair of connection support plates 5 and 6 on the lower side of the roll holding shaft so as to pass the tip of the tape-shaped paving material T peeled off from the roll. The gap may be used as a paving material delivery port.

  As described above, the pressing and adhering wheel 2, the front wheel 3, the side wheel 4, and the paving material holding part 5 h constituting the paving material pressing and sticking device 1 are integrally connected by the pair of connection support plates 5 and 6. Thus, the pair of connection support plates 5 and 6 constitutes the main body of the pavement material pressing and sticking device 1.

  Next, operation | movement of the pavement material press sticking apparatus 1 shown in FIGS. 1-9 is demonstrated using FIGS.

  FIG. 10 is a cross-sectional view showing an example of a construction surface having an L-shaped cross section. In FIG. 10, Sh is a horizontal plane, and Sv is a rising surface that rises almost vertically from the horizontal plane Sh. δ is the angle of the corner that is the intersection of the horizontal surface Sh and the rising surface Sv, and in the case of FIG. 10, the angle δ of the corner is approximately 90 degrees. In order to press and paste the paving material T on the L-shaped construction surface, first remove the large irregularities in the vicinity of the corner in advance, then clean the horizontal surface Sh and the rising surface Sv, if necessary Then, a primer is applied to the horizontal surface Sh and the rising surface Sv.

When application of the primer is completed, the pavement material pressing and sticking apparatus 1 is set on a construction surface having an L-shaped cross section. FIG. 11 is a rear view of the pavement material pressing and sticking apparatus 1 in a state set on the construction surface shown in FIG. 10. In the pavement material pressing and sticking apparatus 1 of this example, the pair of connection support plates 5 and 6 are inclined 45 degrees from the vertical direction, and the supporting shaft 11 of the pressing and sticking wheel 2, in other words, the first rotation axis R _1. since is perpendicular to both of the pair of connecting support plates 5 and 6, the plane P including the joint surfaces of the two bottom surface of the truncated cone 2 ₁ and 2 ₂ constituting the outer shape of the pressing lamination Chakuwa 2 from a vertical direction Tilt 45 degrees. Further, since the angle alpha ₁ and alpha ₂ between the bottom surface and the side surfaces of the two in the truncated cone 2 ₁ and 2 ₂ are both equal 45 degrees, as shown in FIG. 11, the construction of the corner portion 12 of the pressing lamination Chakuwa 2 Ategai snugly entrance corner surface, and, in a state where the two sides of the truncated cone 2 ₁ and 2 ₂ constituting the outer shape of the pressing lamination Chakuwa 2 to each contact and the horizontal plane Sh and rising surfaces Sv, pavement The material press sticking apparatus 1 can be set.

  Next, the tip of the tape-shaped pavement material T held by the pavement material holding portion 5h of the pavement material pressing and sticking apparatus 1 is peeled off from the roll and pulled out through the pavement material delivery port 15, and a predetermined location. Are pressed and adhered to both the horizontal surface Sh and the rising surface Sv located in front of the pressure adhering wheel 2 so that the bent corners fit into the corners. The tape-shaped paving material usually has a release sheet on one side and is wound and laminated in multiple layers with the release sheet side inward, so the tape-shaped paving material pulled out through the paving material delivery port 15 The material T can be pressed and adhered to both the horizontal surface Sh and the rising surface Sv, with the release sheet on the upper side and the adhesive surface without the release sheet on the lower side.

  The pressing and pasting operations so far are performed manually. There is no particular limitation on the length of the tape-shaped paving material T to be first pressed and pasted, but a portion of about 5 to 15 cm between the paving material delivery port 15 and the pressing and pasting wheel 2 is horizontal. It is sufficient to press and stick to both Sh and the rising surface Sv. When the tape-shaped paving material T has a folding recess, it is convenient because the tape-shaped paving material T can be folded at a predetermined location very easily.

  When the pressing and pasting of the tip portion of the tape-shaped paving material T is completed, the paving material pressing and pasting device 1 is gradually advanced toward the front wheel 3, and the paving material T that has already been pressed and pasted. The pressure adhering wheel 2 is moved on the top. FIG. 12 is a rear view of the pavement material pressing and sticking apparatus 1 in this state.

As shown in FIG. 12, the pressing and adhering wheel 2 is positioned on the pavement material T that has been previously pressed and pasted by human power. From this state, for example, the operation rod mounting portion 9 is indicated by a broken line in the figure. The operation rod 17 shown is attached, and a force is applied to the operation rod 17 to advance the pavement material pressing and sticking device 1 in the direction of the front wheel 3. As the pavement material pressing and sticking device 1 advances in the direction of the front wheel 3, the tape-like pavement material T is pressed and stuck to both the horizontal surface Sh and the rising surface Sv while being bent by the pressing and sticking wheel 2. It will be worn. With this pressing and sticking, the tape-shaped paving material T held in the paving material holding portion 5h is drawn out from the paving material delivery port 15 one after another, and the roll of the paving material T is the paving material holding portion. Rotate for 5h. In this case, among the pressed adhered Chakuwa two truncated cones 2 ₁ constituting the second geometry and 2 _2, the height h ₁ of the frustoconical 2 ₁ located on the lower side, of the truncated cone 2 ₂ positioned on the upper side Since it is larger than the height h ₂ , that is, h ₁ > h ₂ , the pavement material T can be pressed and adhered to the horizontal surface Sh wider than the rising surface Sv. When it is desired to press and stick the paving material T to the rising surface Sv wider than the horizontal plane Sh, it is sufficient to set h ₁ <h ₂ .

  By the above operation, the tape-shaped paving material T is pressed and adhered to both the horizontal surface Sh and the rising surface Sv of the construction surface having an L-shaped cross section while being bent one after another. At the start of pressing and sticking, the operator takes out the tip portion of the tape-like paving material T from the paving material delivery port 15, bends it at a predetermined location, and presses and sticks to both the horizontal surface Sh and the rising surface Sv. After wearing it, it is only necessary to advance the pavement material pressing and sticking apparatus 1 in the direction of the front wheel 3 through the operation rod 17, so that the pressing and sticking work of the pavement material T is very efficient. It can be done promptly. Further, although depending on the length of the operation rod 17, the operator can apply pressure to the operation rod 17 in a standing posture to advance the pavement material pressing and pasting apparatus 1 to perform pressing and pasting work. So you can get the advantage of being freed from the hard work that you had to do in the middle and squatting.

Note that the explanation of the above-mentioned pressing and sticking operation is for a construction surface where the corner angle δ is 90 degrees or approximately 90 degrees, but when the corner angle δ is an acute angle or an obtuse angle, the pressure sticking operation is performed. angle of the corner portion 12 of the wheel 2 (i.e., the angle alpha ₁ and the angle sum of the alpha ₂₎ may be brought into coincidence with the angle of the internal corner of the construction surface the interest [delta], of the paving material pressing sticking device 1 The pressing and sticking operation is basically the same. In addition, when the angle δ of the entering corner of the target construction surface is an acute angle or an obtuse angle, the inclination angle from the vertical direction of the pair of connection support plates 5 and 6 may remain 45 degrees. The angle may be changed to ½ of the corner angle δ.

  FIG. 13 is a plan view showing another example of the pavement material pressing and sticking apparatus of the present invention, and shows only the pressing and sticking wheel 2, the front wheel 3, and the side wheel 4.

As shown in FIG. 13, in the pavement material pressing and sticking device 1 of this example, the side wheel 4 is pivotally supported around the fourth rotation axis R _{4 that} is deviated from the third rotation axis R ₃ described above. Has been. That is, the side wheel 4, the third rotation axis R _3, across the side wheel 4, the side closer farther from the plane P including the bonding surface of the pressing bonded two truncated cone constituting the Chakuwa 2 2 ₁ and 2 ₂ than the side rotates in the horizontal about a fourth rotation axis R ₄ which is shifted in a direction located forward in the traveling direction.

In the paving material pressing attaching apparatus 1 of the present embodiment, the front wheel 3 is rotatably supported around a fifth rotation axis R ₅ that is offset from the second rotation axis R ₂ described above. That is, the front wheel 3, opposite the second rotation axis R _2, is the side plane P containing the joining surfaces of the two truncated cones 2 ₁ and 2 ₂ constituting the pressed adhered Chakuwa 2 across the front wheel 3 is tilted rotates in the fifth about a rotation axis R ₅ which is shifted in a direction located in the direction of travel than.

The rotation axis of the side wheel 4 and / or the front wheel 3 is the fourth rotation axis R ₄ with the third rotation axis R ₃ shifted as described above, or the second rotation axis R ₂ is shifted as described above. In the case of the 5 rotation axis R ₅ , the pavement material pressing and sticking device 1 is made to advance in the direction of the front wheel 3, so that the pavement material pressing and sticking device 1 naturally has an L-shaped construction surface. Since it is pressed against the corner of the sheet and proceeds along the corner, an advantage that the paving material T can be pressed and adhered more reliably can be obtained. Note that the rotation axis as described above may be shifted only for the front wheel 3 or the side wheel 4, or for both the front wheel 3 and the side wheel 4.

Note that there in case where the inclination angle of the second horizontal axis of rotation R ₂ is the rotational axis of the front wheel 3 is different from the tilt angle β from the horizontal surface of the first rotating shaft R ₁ is the rotational axis of the press bonded Chakuwa 2 even, in the same manner as described above, the second rotation axis R ₂ is a rotary shaft of the front wheel 3 by a fifth rotational axis R ₅ which is shifted as described above, the progress of the paving material pressing sticking device 1 Accordingly, the pavement material pressing and sticking device 1 can be naturally pressed against the corner of the construction surface having an L-shaped cross section. Moreover, even if not located between the third rotation shaft R ₃ is first rotating shaft as the rotational axis of the side wheel 4 R ₁ and the second rotation axis R _2, in the same manner as described above, the side wheel 4 the third rotation shaft R ₃ is a rotary shaft by the fourth rotation axis R ₄ shifted as described above, with the progress of paving material pressing attaching apparatus 1, paving material pressing sticking device 1 Can be naturally pressed against the corner of the L-shaped construction surface.

FIG. 14 shows still another example of the pavement material pressing and sticking apparatus of the present invention. Figure 14 is similar to FIG. 7, viewed while cutting the paving material pressing sticking device 1 in a plane containing the two joint surfaces of the truncated cone 2 ₁ and a truncated cone 2 ₂ from the side of the connecting support plate 6 Figure It is. In this example, the connection support plate 5 is provided with a long hole 5i that passes through the center C of the arc where the rotation centers of the rotation rollers 8a to 8h are arranged, passes through the connection support plate 5, and extends in the vertical direction. Yes.

  FIG. 15 is a diagram illustrating an example of a roll holding shaft 50 that is used by being attached to the connection support plate 5 of the pavement material pressing and sticking apparatus 1 illustrated in FIG. 14. 15A is a left side view of the roll holding shaft 50, FIG. 15B is a partially cutaway front view of the roll holding shaft 50, and FIG. 15C is a right side view of the roll holding shaft 50.

  The roll holding shaft 50 is provided with an engagement shaft 51 such as a bolt coaxially at one end and a shaft body 53 provided with a flat tab portion 52 at the other end, and a through hole 54 inside thereof. And a rotating roller 55 that is rotatably supported by the shaft body 53 via a bearing (not shown). The engaging shaft 51 and a part of the shaft body 53 protrude from the end surface on one end side of the rotating roller 55. Further, the inner diameter of the other end side of the through hole 54 of the rotation roller 55 is set to a size that allows the knob portion 52 to rotate inside the through hole 54, and the knob portion 52 is accommodated in the rotation roller 55. The length of the rotating roller 55 is set to a length that substantially matches the width of the tape-shaped paving material used together. Further, the outer diameter of the rotating roller 55 is set to a diameter that substantially matches the inner diameter of the central hole of the tape-shaped paving material used together.

  In this example, it has a long hole 5i, and is attached to the connection support plate 5, the rotating rollers 8d to 8f, and the connection support plate 5 that hold the paving material wound in a roll placed thereon. The roll holding shaft 50 to be formed constitutes a paving material holding part 5h for holding a tape-like paving material wound in a roll shape.

  FIG. 16 is a diagram illustrating an example of a tape-shaped paving material T wound in a roll shape. As shown in FIG. 16, the tape-shaped paving material T wound in a roll shape may be deformed into an irregular shape due to pressure or impact during storage or transportation. Even if it is the material T, the paving material holding | maintenance part 5h comprised from the member shown in FIG.14 and FIG.15 can be hold | maintained so that rotation is possible smoothly.

  That is, the rotating roller 55 of the roll holding shaft 50 is inserted into the center hole Th of the tape-shaped paving material T wound in a roll shape. At this time, since the length of the rotating roller 55 substantially coincides with the width of the paving material T as described above, the tape-shaped paving material T wound around the other end of the rotating roller 55 in a roll shape. When the surface on the other end side is substantially flush with the surface on the other end side, only a part of the engaging shaft 51 and the shaft body 53 protrudes from the surface on the one end side of the tape-shaped paving material T wound in a roll shape. It becomes. Further, since the outer diameter of the rotating roller 55 is substantially the same as the inner diameter of the center hole Th, the rotating roller 55 can be inserted so as to fit the center hole Th. It is possible to prevent deviations between them. Subsequently, the engagement shaft 51 is inserted into the long hole 5i from the connection support plate 6 side, and a mounting member such as a nut (not shown) is engaged with the engagement shaft 51 protruding from the opposite side of the long hole 5i. 50 is attached to the connection support plate 5. Since the knob portion 52 is attached to the shaft body 53, the roll holding shaft is rotated by rotating the attachment member such as a nut while holding the shaft body 53 so as not to rotate by pinching the knob portion 52 with a finger. 50 can be attached to the long hole of the connection support plate 5 together with the paving material T.

  In addition, since the hole provided in the connection support plate 5 to which the roll holding shaft 50 is attached is a long hole extending in the vertical direction, the mounting position of the roll holding shaft 50 can be freely changed, and the winding radius can be changed. There is an advantage that the paving material T can be attached to an appropriate position of the connection support plate 5 via the roll holding shaft 50 without being limited to the size. In addition, the roll holding shaft 50 is attached not to be firmly attached to the connection support plate 5 but to the extent that it can freely move along the long hole, and as the tape-like paving material T is unwound, the paving material T is wound. As the radius decreases, the mounting position of the roll holding shaft 50 may move downward along the long hole.

  According to the pavement material pressing and sticking apparatus 1 of this example, the tape-shaped pavement material T wound in a roll shape and formed into a substantially cylindrical shape is of course stored after being formed into a substantially cylindrical shape, or Even when using a paving material T that has been deformed in response to pressure or impact from the outside during transport, etc., the paving material T is smoothly rotated on the paving material holding part 5h, and the paving material T is sent from the paving material delivery port 15. Can be sent out.

  17 to 19 show still another example of the pavement material pressing and sticking apparatus of the present invention. 17 is a left side view of the pavement material pressing and sticking apparatus 1, FIG. 18 is a front view thereof, and FIG. 19 is a rear view thereof. The pavement material pressing and sticking apparatus 1 of this example has the same basic configuration as the pavement material pressing and sticking apparatus 1 shown in FIGS. 1 to 6, and the same members are denoted by the same reference numerals. . Hereinafter, the pavement material pressing and sticking apparatus 1 of this example will be described focusing on a different configuration from the pavement material pressing and sticking apparatus 1 shown in FIGS.

The press sticking wheel 2 of this example is the press shown in FIGS. 1 to 6 in that the corner portion 12 is provided so as to be close to the connection support plate 6 of the pair of connection support plates 5 and 6. Although it is different from the sticking wheel 2, it has an outer shape in which two truncated cones having the same bottom radius are joined at the bottom with the bottom centers being aligned, passing through the center of the bottom and perpendicular to the bottom. in terms of rotating the tilted first around a rotation axis R ₁ was no different.

Further, the front wheel 3 of the present example is not centered in the width direction on the plane including the joint surface between the bottom surfaces of the two truncated cones constituting the outer shape of the pressure adhering wheel 2, and the plane is inclined. Although different from the front wheel 3 of the example shown in FIGS. 1 to 6 in that it is shifted to the side, the difference is that it rotates around the second rotation axis R ₂ parallel to the first rotation axis R _1. Absent.

Further, the side wheel 4 of this example is different from the example shown in FIGS. 1 to 6 in that it is attached to the connection support plate 5 via the bracket 20, but the first rotation axis R ₁ and the second rotation axis. R is between _2, wherein in terms of rotation to a horizontal third around the rotation axis R ₃ located on the vertical plane parallel to the first rotation axis R ₁ no different.

  However, in the pavement material pressing and sticking apparatus 1 of this example, the lower part including the lower end 5e of the connection support plate 5 located on the lower side of the pair of connection support plates 5 and 6 is a tape-shaped pavement that is sent out. In order to prevent the guide member from being deformed or damaged due to contact with the unevenness on the construction surface, the connecting support plate 5 is provided. A guide member protection member 21 is attached.

  The guide member protection member 21 is attached to the connection support plate 5 via the bracket 22 so that its lower end is positioned below the lower end 5e of the connection support plate 5, and in this example, the guide member protection member 21 is protected. The member 21 includes a ball 23 and a casing 24 that holds the ball 23 so that it can roll and does not fall off, and projects the lower end of the ball 23 from its lower side.

  For this reason, according to the pavement material pressing and sticking apparatus 1 of this example, even if there is a convex portion on the horizontal construction surface, the guide member protection is performed before the lower end 5e of the connection support plate 5 that is the guide member. Since the member 21 abuts on the convex portion and the connection support plate 5 to which the guide member protection member 21 is attached is lifted upward, the lower end 5e of the connection support plate 5 also serving as the guide member is a convex portion on the construction surface. And the lower end 5e of the connection support plate 5 serving also as a guide member is prevented from being deformed or damaged. Moreover, since the guide member protection member 21 can abut on the convex portion of the construction surface and roll on the construction surface, the pavement can be paved even if the lower end of the guide member protection member 21 abuts on the convex portion of the construction surface. The material pressing and sticking apparatus 1 can proceed on the construction surface without any trouble. In this example, as the guide member protection member 21, the guide member protection member 21 whose lower end rolls on the construction surface when contacting the construction surface is illustrated, but instead, The guide member protection member 21 whose lower end slides on the construction surface when abutting against the construction surface may be used.

In this example, the center of the front wheel 3 in the width direction is disposed between the pair of connection support plates 5 and 6, but the center in the width direction is the lower side of the pair of connection support plates 5 and 6. The front wheel 3 may be arranged so as to be positioned below the connection support plate 5. Even if it is provided at such a position, it can receive a part of the load of the pavement material pressing and sticking apparatus 1 and can rotate forward in the traveling direction. Further, the shape of the front wheel 3 may be a truncated cone, and the side surface may be in contact with the horizontal plane and rotate. In this case, the second rotation axis R ₂ is a rotary shaft of the front wheel 3 is the axis inclined from the horizontal.

  Moreover, if it is required in order to smoothly advance the pavement material pressing and sticking apparatus 1 along the corner of the construction surface having an L-shaped cross section, an appropriate position of the pavement material pressing and sticking apparatus 1, for example, connection support An auxiliary wheel that rotates about the vertical rotation axis and rolls on the rising surface may be provided on the front side in the traveling direction of the plate 6.

  20 to 22 show still another example of the pavement material pressing and sticking apparatus of the present invention. 20 is a front view of the pavement material pressing and sticking apparatus 1 in contact with an L-shaped construction surface, FIG. 21 is a sectional view taken along the line II-II in FIG. 20, and FIG. FIG. 22B is a sectional view taken along the line IV-IV in FIG. 21, and FIG. 22C is a sectional view taken along the line VV in FIG. In FIG. 20, the front wheels 3 are not drawn for convenience of explanation.

In the present example, of the two truncated cones 21 and 22 constituting the outer shape of the pressure adhering wheel 2, the height of the truncated cone 22 positioned above the height h ₁ of the truncated cone 21 positioned on the lower side. Since the length h ₂ is large, that is, h ₁ <h ₂ is set, the pavement material T can be pressed and adhered to the rising surface Sv more widely than the horizontal surface Sh. In this example, the plane P including the joint surface between the bottom surfaces of the truncated cones 21 and 22 is inclined to the right when the pavement material pressing and sticking device 1 is viewed from the front.

  In this example, a paving material delivery port 15 is set between the rotating roller 8 a and the rotating roller 8 b, and a guide roller is provided between the paving material delivery port 15 and the pressure adhering wheel 2. 10, a bending contact piece 25, a bending auxiliary member 26, and a support member 27 are provided. Hereinafter, these members will be described in detail.

  The guide roller 10 is a roller for guiding the tape-shaped pavement material T fed from the pavement material delivery port 15 between the lower end of the bending contact piece 25 and the bending auxiliary member 26, and a pair of couplings The support plates 5 and 6 are rotatably mounted. The tape-like paving material T fed from the paving material delivery port 15 is guided between the lower end of the bending contact piece 25 and the bending auxiliary member 26 after contacting the lower surface of the guide roller 10.

  The bending contact piece 25 is located between the pressure adhering wheel 2 and the pavement material delivery port 15 and is attached between the pair of connection support plates 5 and 6 via a fixture (not shown) such as a bracket. Yes. In this example, the bending contact piece 25 is a thin wedge-shaped member having a triangular cross section, and has a linear lower end portion facing the direction of the corner of the construction surface having an L-shaped cross section, The linear lower end portion is located on the plane P including the joining surface of the two truncated cones constituting the press adhering wheel 2. Further, the bent contact piece 25 has a front end thereof, that is, an end portion on the pavement material delivery port 15 side at a position higher than a rear end thereof, that is, an end portion on the pressing and adhering wheel 2 side. The front end and the rear end of the contact piece 25 are rounded at the lower side so that the paving material T can be smoothly received and delivered.

  On the other hand, the bending assisting member 26 includes guide rollers 28 to 33 attached to the support member 27. The support member 27 has a center in the width direction on the plane P including the joint surface of the two truncated cones constituting the press adhering wheel 2, and between the press adhering wheel 2 and the paving material delivery port 15. Thus, the pair of connection support plates 5 and 6 are attached via a fixture (not shown) such as a bracket so as to be positioned below the lower end portion of the bent contact piece 25. Similarly to the bent contact piece 25, the support member 27 has a front end thereof, that is, an end portion on the pavement material delivery port 15 side, which is higher than a rear end thereof, that is, an end portion on the press bonding wheel 2 side. The pavement material pressing and sticking apparatus 1 is inclined and arranged so as to become lower toward the rear in the traveling direction. However, the inclination angle is gentler than the inclination angle of the bending contact piece 25, and the distance between the lower end portion of the bending contact piece 25 and the support member 27 is closer to the pressing and adhering wheel 2. It is getting shorter.

  Each of the guide rollers 28 to 33 is a support member such that the guide rollers 28 and 29, 30 and 31, and 32 and 33 are paired and have a V shape with the bent contact piece 25 interposed therebetween. 27 are attached at right angles to the support member 27 at different positions. In other words, the three pairs of guide rollers 28 and 29, 30 and 31, 32 and 33 constituting the bending assisting member 26 are arranged on two planes intersecting in a V-shaped cross section. The intersecting line of the planes of the sheets is on the plane P including the joining surface of the two truncated cones constituting the press adhering wheel 2 and is located below the lower end portion of the bent contact piece 25. The support member 27 is disposed on the intersection line of the two planes, and the distance between the intersection line of the two planes and the lower end portion of the bent contact piece 25 is determined by the paving material delivery port. As it goes from 15 to the pressure adhering wheel 2, it gradually becomes shorter. For this reason, as described above, the distance between the lower end portion of the bent contact piece 25 and the support member 27 becomes shorter as it approaches the pressing and adhering wheel 2. Further, since the guide rollers 28 to 33 are attached at right angles to the support member 27, the rotation axes of the guide rollers 28 to 33 are orthogonal to the support member 27.

As shown in FIGS. 21 and 22, each of the pair of guide rollers 28 and 29, 30 and 31, and 32 and 33 attached so as to be V-shaped with the bent contact piece 25 interposed therebetween. The V-shaped opening angle to be formed gradually becomes narrower from the pavement material delivery port 15 side toward the pressure sticking wheel 2 side. The V-shaped opening angle refers to the angles between the rotation axes R _{28 to} R ₃₃ of the guide rollers _{28 to 33} and the plane P, respectively, θ ₂₈ , θ ₂₉ , θ ₃₀ , θ ₃₁ , θ ₃₂ , In the case of θ ₃₃ , it means θ ₂₈ + θ ₂₉ , θ ₃₀ + θ ₃₁ , or θ ₃₂ + θ ₃₃ (V-shaped opening angle of the pair of guide rollers 28 and 29 = θ ₂₈ + θ ₂₉ )> (pair of pairs V-shaped opening angle of the guide rollers 30 and 31 = θ ₃₀ + θ ₃₁ )> (V-shaped opening angle of the pair of guide rollers 32 and 33 = θ ₃₂ + θ ₃₃ ). In other words, the crossing angle of the two planes that intersect the three pairs of guide rollers 28 and 29, 30 and 31, 32 and 33 constituting the bending assisting member 26 in a V-shaped cross section is as follows. As it goes from the pavement material delivery port 15 side to the pressure sticking wheel 2 side, it gradually becomes narrower.

  In the pavement material pressing and sticking apparatus 1 of the present example in which the bending auxiliary member 26 composed of the bending contact piece 25 and the guide rollers 28 to 33 as described above is provided, from the pavement material delivery port 15. When the tape-shaped paving material T is sent out, the tape-shaped paving material T is guided between the folding contact piece 25 and the folding auxiliary member 26 while contacting the lower surface of the guide roller 10. The upper surface of the paving material T is in linear contact with the lower end portion of the bending contact piece 25, and the lower surface of the paving material T is the folding auxiliary member 26 on both sides of the lower end portion of the bending contact piece 25. It contacts the guide rollers 28 to 33 constituting the.

  The guide rollers 28 to 33 are attached to a support member 27 positioned below the lower end portion of the bent contact piece 25 so as to be V-shaped with the bent contact piece 25 interposed therebetween. The V-shaped opening angle is gradually narrowed toward the pressing and adhering wheel 2 side, and the distance between the lower end of the bent contact piece 25 and the support member 27 is also on the pressing and adhering wheel 2 side. Since the tape-shaped paving material T led between the bending contact piece 25 and the bending auxiliary member 26 is gradually shortened as it goes, the upper surface is the lower end portion of the bending contact piece 25. The lower surface of the bent contact piece 25 is in contact with the guide rollers 28 to 33 on both sides of the lower end of the bent contact piece 25, and is gradually bent into an L-shape that matches the shape of the construction surface. 2 will be supplied below.

  In the example described above, the guide rollers 28 to 33 constituting the bending assisting member 26 are three pairs, but the number is not limited to three pairs, and may be one pair, two pairs, or four pairs or more. . Further, instead of the guide rollers 28 to 33, a member such as a bar or a plate having a flat surface or a curved surface through which the tape-like paving material T passes while smoothly sliding on it, instead of rotating itself, The bending assisting member 26 may be configured by arranging it in a V shape with the bending contact piece 25 interposed therebetween. In any case, the bending assisting member 26 is two planes intersecting in a V-shaped cross section, and the intersecting line is on the plane P including the joining surfaces of the two truncated cones constituting the pressing and adhering ring 2. And the line of intersection may be arranged on two planes located below the lower end of the bent contact piece 25, and the specific shape, structure, etc. thereof may be changed as appropriate. Is possible. However, it is preferable that the bending assisting member 26 is constituted by the guide rollers 28 to 33 described above in order to be brought into contact with the lower surface of the tape-like paving material having adhesiveness and bend it.

  23 to 25 show still another example of the pavement material pressing and sticking apparatus of the present invention. 23 is a plan view of the pavement material pressing and sticking device 1, FIG. 24 is a left side view thereof, and FIG. 25 is a partial cross-sectional view taken along the line VI-VI in FIG. The same members as those shown in the above are given the same reference numerals.

The members 60 are connected. The connecting member 60 includes a front plate 61 attached to the main body front portion 18, a rear plate 62 attached to the main body rear portion 19, a vertical bar 63, a plurality of front side connections fixed to the front plate 61 and the vertical bar 63. A plurality of rear connection plates 65 are attached to the plate 64 and the rear plate 62 and have openings through which the vertical bar 63 is rotatably inserted. Other configurations of the pavement material pressing and sticking apparatus 1 of this example are the same as those of the pavement material pressing and sticking apparatus 1 described above.

  Since the main body of the pavement material pressing and sticking apparatus 1 of this example is divided into the main body front part 18 and the main body rear part 19 and connected by the connecting member 60, the main body front part 18 and the main body rear part 19 are They are rotatable around a vertical bar 63 that is a vertical axis.

  Therefore, according to the pavement material pressing and sticking device 1 of this example, the main body front portion 18 and the main body rear portion 19 are vertical even if the rising surface Sv on the L-shaped construction surface is curved left and right. By rotating around the axis, the front wheel 3 and the pressure adhering wheel 2 can be made to follow the corner formed by the horizontal surface Sh and the rising surface Sv, and the taped paving material can be applied to the curved construction surface. An advantage is obtained in that T can be pressed and pasted and securely stuck.

  In this example, the main body of the pavement material pressing and sticking apparatus 1 is composed of two parts, a main body front portion 18 and a main body rear portion 19 that are rotatably connected to each other around a vertical axis. However, it may be composed of three or more parts that are pivotably connected to each other around a vertical axis.
