Description
- The present invention relates to an outer surrounding body such as a roof, wall or the like which is worked as a sheet for use in construction by covering the surface of a thin metal sheet with a synthetic resin film; in which waterproofing and water-tightness are improved in the locations where the construction sheets are connected to each other or the mounting locations of trough members, and the working characteristics and finish are greatly improved, and also relates to an outer surrounding body for use in construction and a manufacturing apparatus for the same which make it possible to achieve an extremely good finish in terms of waterproofing and water-tightness regardless of the degree of experience of the workers.
- In the past, there have commonly been problems in areas of heavy snow accumulation of the joint parts (connecting parts) of roofs becoming immersed in water, thus causing leakage such as ceiling leakage or the like to occur. In recent years, furthermore, because of the popularization of verandah roofs, there has been an increase in cases where roofs become immersed in water due to the cultivation of plants and the like, so that a demand has arisen for roofs with an even higher degree of water-tightness. Furthermore, a patent reference (Japanese Patent Application Laid-Open No. 7-150703) exists which indicates a connecting structure that is used to connect roofing sheet members to each other. In this structure, bent parts that are used for connection are formed on both sides of flat roofing sheets in the lateral direction, and these bent parts are connected to each other in a bent form.
- In the abovementioned patent reference, invasion by rain water or the like can be checked to some extent by fastening the connecting bent parts of adjacent roofing sheet members to each other. Furthermore, connecting parts of construction sheets include various types of connecting parts, such as parts that are fastened together, parts that are engaged and the like. In most cases, however, in order to achieve more complete waterproofing and obtain a higher degree of water-tightness, a filling type sealing material is mounted in the locations where adjacent roofing sheets are connected to each other. In the case of long-term use, however, such sealing materials lose flexibility and elasticity, so that cracking and peeling occur in the locations where connections are made, thus forming gaps so that the water-tightness gradually deteriorates. For such reasons, a considerable degree of uneasiness remains in filling type sealing materials in terms of security and reliability.
- Accordingly, resin welding has also been used in recent years. However, this resin welding is a process in which a hot air draft is blown onto the connecting parts during working, so that a resin welding material is melted. Accordingly, working is performed so that the connecting locations are filled with a molten resin material while this resin material is melting at a high temperature. This high temperature that is generated causes local thermal strain of the parts that are subjected to this high temperature. Deformation of the construction sheets caused by this thermal strain is deemed to produce an unacceptable finish, and the thermal welding materials also fail to have a clean finish, leading to a conspicuous deterioration in the external appearance. Furthermore, if such high temperatures must be used, it is likewise impossible for the resin welding materials to achieve a sufficiently close affinity with the surface of the metal roof, so that good resin welding cannot be performed.
- Accordingly, it is conceivable that a high degree of water-tightness might be achieved by injecting a molten resin into the abovementioned connecting parts by resin welding.
- However, even if direct resin welding is performed on thin metal plates or coated steel plates, a strong adhesion is not obtained. In other words, the components of the welding material and the surface of the member being welded must be the same. Furthermore, in cases where the core part is a thin metal sheet, the heat that is absorbed during welding escapes more readily via the metal sheet (than it does in the case of thin metal sheet part covered by a synthetic resin), so that it is necessary to slow the running of the welding apparatus by 10% or more in order to elevate the temperature to a specified temperature.
- In such resin welding means, a hot air draft is blown onto the locations of the connecting parts, so that these locations are heated to a high temperature; at the same time, welding is performed by extruding the resin welding material while melting this material. In order to perform this resin welding, an apparatus for feeding out the resin welding material and a hot air draft generating apparatus for heating the area around the welding location must be provided. Since this resin welding is performed with the speed at which the welder is moved, the amount of resin welding material that is fed out and the like constantly maintained at appropriate values, this has a great effect on the resin welding finish. Accordingly, in the case of resin welding, an experienced technique is required to some extent, so that the acceptability of the finish is determined by the experience of the worker.
- Specifically, in the case of an experienced worker, the resin welding can be finished in an extremely clean state. However, in the case of an inexperienced worker, the following problem arises: namely, the filling state of the resin welding is uneven, and the hot air draft apparatus may be applied too strongly so that the surrounding area is melted to a greater extent than necessary, thus causing melting of the resin layer covering the roofing sheet member, so that the underlying metal is exposed, and the resin layer can no longer perform the function of a protective film, or it may become impossible to reach the temperature required for the favorable performance of resin welding in the areas surrounding the welding locations, so that sufficient and secure resin welding cannot be performed.
- It is an object of the present invention to achieve favorable waterproofing and water-tightness in the locations where construction sheets are connected to each other as described above, to achieve favorable finishing in these locations, to improve the welding characteristics using steel sheets covered with the same components as the welding material, and to make it possible to perform resin welding with an extremely good finish by setting the areas around the connecting locations at an appropriate temperature and filling the connecting locations with an appropriate amount of the welding material, regardless of the degree of experience of the worker.
- In the present invention, in order to solve the abovementioned problems, a plurality of construction sheets in which a thin metal sheet part and a synthetic resin film are constructed in layer form, and each sheet consists of a main sheet, an overlapped part which is formed on one side of this main sheet in the lateral direction, an overlapping part which is formed on the other side of the main sheet in the lateral direction, and which can overlap with the abovementioned overlapped part, and a fastening part which is formed in a substantially flat shape from the outside end of the abovementioned overlapped part, are disposed side by side, a portion of the main sheet of one construction sheet that is located near the overlapping part is placed on the fastening part of an adjacent construction sheet and the overlapping part is overlapped with the abovementioned overlapped part, and an area extending from the vicinity of the outer ends of the overlapping parts of both construction sheets to the vicinity of the inside corner parts of the overlapped parts is fused with said synthetic resin film via a resin welding member, thus producing effects such as reducing the occurrence of deformation in response to thermal strain caused by locally high temperatures in the outer surrounding body worked as a construction member that is formed by covering the surface of a thin metal sheet with a synthetic resin film, improving the finish of the resin welding and the like.
- Furthermore, in the present invention, it is possible for the bent end edges to support the main sheets of the adjacent construction sheets from the back side in a state in which the overlapped parts and overlapping parts of the adjacent construction sheets are overlapped, by forming a construction outer surrounding body in which bent end edges are folded back above from the outside ends of the abovementioned fastening parts in the invention described above. Accordingly, the fastening parts can be prevented from contacting the head parts or the like of the fastening fittings that are fastened to the underlying parts, and a stable connected structure of the adjacent construction sheets can be obtained.
- Furthermore, in the present invention, it is possible to improve the working efficiency by forming a construction outer surrounding body in which engaged parts are formed in the abovementioned overlapped parts, engaging parts are formed in the abovementioned overlapping parts in positions corresponding to the abovementioned engaged parts, and the abovementioned engaged parts and engaging parts are engaged and fastened, in the two inventions described above.
- Furthermore, in the present invention, it is possible to achieve an extreme simplification of the water-tight mounting between the eave and trough member by forming a construction outer surrounding body in which an eave location in the end part of the abovementioned construction sheet in the longitudinal direction and a trough member formed by constructing a thin metal sheet part and a synthetic resin film into layer form are fused with the abovementioned synthetic resin film via the abovementioned resin welding member in the three inventions described above.
- Furthermore, in the present invention, it is possible to obtain a construction outer surrounding body in which the fusion of the resin welding member and the synthetic resin film is favorably performed, the finish is extremely clean and favorable, and the waterproof seal possesses durability, by forming a construction outer surrounding body in which the chief component of the abovementioned synthetic resin film is a thermoplastic resin, in the four inventions described above.
- Furthermore, in the present invention, it is possible to obtain resin welding with an extremely good finish in the connection locations (connecting parts) of the adjacent construction sheets, regardless of the degree of experience of the worker, so that the connection locations can be given more secure water-tightness and air-tightness, by constructing a construction outer surrounding body manufacturing apparatus comprising a resin welder part which is constructed from a car part equipped with a running part that is caused to rotate by a driving part, a welding member feeding apparatus which feeds out the molten resin welding member, and a hot air blast apparatus which heats the connection locations (connecting parts) of the abovementioned adjacent construction sheets, in an apparatus in which a plurality of construction sheets in which a thin metal sheet part and a synthetic resin film are constructed in layer form, and each sheet has a main sheet, an overlapped part which is formed on one side of this main sheet in the lateral direction, an overlapping part which is formed on the other side of the main sheet in the lateral direction, and which can overlap with the abovementioned overlapped part, and a fastening part which is formed in a substantially flat shape from the outside end of the abovementioned overlapped part are disposed side by side, and resin welding is performed in the connecting parts where the overlapping parts are caused to overlap with the overlapped parts.
- Furthermore, in the present invention, the connection locations of adjacent construction sheets can be filled with a molten resin welding member while being tightened, so that a good finish can be obtained, by constructing a construction outer surrounding body manufacturing apparatus in which a finishing roll part comprising a tightening roll that tightens the connection locations of the adjacent construction sheets, and a supporting roll, is mounted on the abovementioned car part.
- Furthermore, in the present invention, the manufacturing apparatus B of the present invention can be accurately moved along the connection locations (connecting parts) of adjacent construction sheets, so that the filling of the molten resin welding member can be accomplished with a much more accurate and favorable finish, by constructing a construction outer surrounding body manufacturing apparatus in which a guide ring which is disposed on the top of the connection locations of the abovementioned construction sheets that are adjacent in the forward-rearward direction is provided on the abovementioned car part.
- Furthermore, in the present invention, the planning of the work of resin welding by means of the manufacturing apparatus can be accomplished with good efficiency by constructing a construction outer surrounding body manufacturing apparatus in which the abovementioned resin welder part can be freely set in an appropriate position along the vertical direction with respect to the car part.
- Furthermore, in the present invention, a clean resin welding surface can be obtained by constructing a construction outer surrounding body manufacturing apparatus in which a feed-out nozzle that feeds out at the abovementioned resin welding member to the connection locations (connecting parts) of said adjacent construction sheets is mounted in the welding member feeding apparatus of the abovementioned resin welder part, and a molding surface is formed in this feed-out nozzle.
- Furthermore, in the present invention, the surface shape of the resin welding member can be made polyhedral, and in particular, a structure can be obtained in which the thickness gradually increases in the downward direction in the connection locations (connecting parts), so that the connecting strength in the connection locations (connecting parts) can be greatly improved, by constructing a construction outer surrounding body manufacturing apparatus in which the abovementioned molding surface has a substantially polyhedral shape.
- Furthermore, in the present invention, by constructing a construction outer surrounding body manufacturing apparatus in which a pressing part that presses the main sheets in the vicinity of the connection locations of the adjacent construction sheets is mounted in the feed-out part of the abovementioned welding member feeding apparatus, it is possible to press the main sheets in the vicinity of the connection locations of the adjacent construction sheets by means of this pressing part, so that the areas in the vicinity of the connection locations (connecting parts) can be stabilized in the resin welding work, thus making it possible to prevent vertical deviation in the connection locations (connecting parts) of the adjacent construction plates, so that resin welding with an extremely good finish can be performed.
- Furthermore, in the present invention, resin welding with a good finish can be obtained by constructing a construction outer surrounding body manufacturing apparatus in which the running ring of the abovementioned running part consists of a front ring part and a rear ring part, and both the abovementioned front ring part and rear ring part are rotationally driven by the abovementioned driving part.

First, the raw materials that form the construction sheet A will be described. These raw materials comprise a thin metal sheet part ml that is covered by a synthetic resin film m2. These raw materials are formed into a construction sheet A such as a roofing sheet member, wall sheet member or the like by means of a roll molding machine, and construction outer surrounding bodies used as various building structures such as roofs, walls or the like can be worked using this construction sheet A.
- A concrete example of this thin metal sheet part m1 is a band-form sheet that is long in the longitudinal direction; for instance, a steel member such as a plated steel sheet, colored steel sheet, stainless steel sheet or the like, or a non-ferrous metal member such as an aluminum member, titanium member or the like may be used. This thin metal sheet part ml thickness that allows molding by means of a roll molding hine; the thickness of this thin metal sheet part ml is approximately 0.3 mm to approximately 1.5 mm, and is even more preferably approximately 0.5 mm to approximately 1 mm.
- Next, the synthetic resin film m2 may consist of a synthetic resin of an appropriate type; however, it is desirable that this be a material that can be fused (or welded) to the
resin welding member 8 described later. Furthermore, the chief component of this synthetic resin film m2 may be a thermoplastic resin in some cases. In concrete terms, this consists of a synthetic resin whose chief component is a resin that has thermoplastic properties such as a vinyl chloride resin, olefin type thermoplastic elastomer or the like. The thickness of this synthetic resin film m2 is in the range of approximately 0.1 mm to approximately 1 mm, more preferably in the range of approximately 0.2 mm to approximately 0.5 mm, and is even more preferably approximately 0.25 mm. - Furthermore, a film that has durability is ideal as the synthetic resin film m2. Moreover, the setting of the melting temperature also varies according to the material; however, it is desirable that this melting temperature be set so as to correspond to the use conditions of the construction sheet A. Furthermore, construction sheets A that satisfy the abovementioned conditions also include vinyl chloride steel sheets (ordinarily called “PVC steel sheets”). Moreover, materials which are superior in terms of weather resistance, with a strong resistance to ultraviolet light and contaminated air, and which tend not to show rupture, swelling, cracking or the like, are desirable as the synthetic resin film m2. Concrete examples of desirable materials that satisfy the abovementioned conditions include olefin type thermoplastic elastomers consisting chiefly of ethylene-propylene or the like.
- Furthermore, from the standpoint of environmental protection, it is desirable that the components that form the abovementioned synthetic resin film m2 be constructed from compounds that do not contain any halogens. Specifically, it is desirable that chlorine type chemical substances be excluded from the components making up the synthetic resin film m2, and that this synthetic resin film not be a film that is formed on the basis of organic chlorine compounds. As a result, even if discarded, the synthetic resin film m2 will not generate dioxins, and will have no harmful effects on the environment or on living things.
- The synthetic resin films m2 can be fused to each other by melting the films (by blowing a hot air blast at around 500° C. onto the films), and then pressing the films together following this heating. Furthermore, fusion (welding) with the
resin welding member 8 can also be favorably performed by melting the same resin as the film inside a heating vessel, and extruding this resin on top of the synthetic resin film m2. It is sufficient if theresin welding member 8 is a material that possesses thermoplastic properties; however, it is desirable that this member consist of the same material as the abovementioned synthetic resin film m2. - The construction sheet A is a sheet that forms roofs, walls and the like, and a plurality of different types of such sheets exist. As a basic configuration, all of these respective types of sheets are constructed from a
main sheet 1, anoverlapped part 2, an overlappingpart 3 and afastening part 4. The construction sheet A is formed so that the abovementioned synthetic resin film m2 constitutes the front surface side of themain sheet 1, overlappedpart 2, overlappingpart 3, andfastening part 4. First, in the case of the construction sheet A of the first type, theoverlapped part 2 is formed on one end of the flatmain sheet 1 in the lateral direction as shown inFIG. 2A . - As is shown in
FIG. 2C , this overlappedpart 2 is a part that is caused to rise upward as seen from themain sheet 1, and is formed with a folded-back cross-sectional shape substantially similar to that of a hairpin. Furthermore, the rising part of theoverlapped part 2 on the side of themain sheet 1 constitutes aninside part 2 a, while the rising part on the outside of theoverlapped part 2 constitutes anoutside part 2 b. The location of the bend between themain sheet 1 and theinside surface 2 a of the abovementioned overlappedpart 2 constitutes a corner part K. This corner part K is a location to which the resin weld part or place where resin welding is performed together with the abovementioned overlappingpart 3 is in close proximity. - Next, a
fastening part 4 is formed running toward the outside of the construction sheet A in the lateral direction, on the outside of the lower end of theoutside part 2b of theoverlapped part 2. The location where thisfastening part 4 and the abovementionedoutside part 2 b are connection is a position that is beneath or lower than themain sheet 1. Specifically, thefastening part 4 has a slight step with the abovementionedmain sheet 1. Furthermore, theabovementioned fastening part 4 constitutes a horizontal flat surface that is substantially parallel to themain sheet 1. The dimension of thefastening part 4 in the lateral direction (which is equal to the dimension of the construction sheet A in the lateral direction) is much smaller than the dimension of themain sheet 1 in the lateral direction. - The dimension of the construction sheet A in the lateral direction is approximately 3 meters to 6 meters; within this dimension, it is sufficient if the dimension of the fastening part in the lateral direction is set so that this dimension does not substantially exceed 30 millimeters. However, this dimension may be appropriately set as desired. This
fastening part 4 has the function of fastening the construction sheet A to theunderlying part 5 via afastening fitting 12. Abent end edge 4 a with a shape that is folded back over the fastening part 4 (on the side of the front surface of the fastening part 4) is formed on the outer end of thefastening part 4. In concrete terms, furthermore, the part that connects thefastening part 4 and bent end edger 4 a is formed with a substantially C-shaped or reverse C-shaped cross section. - Next, as is shown in
FIG. 2D , the overlappingpart 3 is formed on the side of the other end of the abovementionedmain sheet 1 in the lateral direction, i. e., on the opposite side from the side on which the abovementioned overlappedpart 2 is formed. In this overlappingpart 3, aninside part 3 a is formed in a rising configuration from the other end of themain sheet 1 in the lateral direction, and anoutside part 3b is formed toward the outside from the upper end of thisinside part 3 a. The place where theinside part 3 a and outsidepart 3 b are connected has a substantially circular arc form or arch form cross-sectional shape, and theinside part 3 a and outsidepart 3 b are smoothly connected to each other at the tip. The overlappingpart 3 overlaps with theoverlapped part 2 of another adjacent construction sheet A. - Furthermore, an
engaged part 2 c is formed on the abovementioned overlappedpart 2, and anengaging part 3 c is formed on the abovementioned overlappingpart 3. Moreover, in construction sheets A, A, . . . that are lined up side by side, a portion of the main sheet of the overlappingpart 3 of each construction sheet A near the overlappingpart 3 of this construction sheet A is placed on theoverlapped part 2 of another adjacent construction sheet A, and the abovementioned engagedpart 2 c andengaging part 3 c are engaged and fastened, so that the overlappingpart 3 is overlapped on the abovementioned overlappedpart 2. Each engagedpart 2 c is formed as a recess in theinside part 2 a of the abovementioned overlappedpart 2. In concrete terms, this part is bent into a cross-sectional shape having substantially the form of a reversed “V” from the area above theinside part 2 a on the side of themain sheet 1, and the abovementioned insidepart 2 a has an inclined shape from the lower end of the portion that is bent into a reversed “V” shape, and is connected to the side of themain sheet 1. - The abovementioned engaged
part 2 c constitutes the lower end of the abovementioned shallow “V” shape. Next, theengaging part 3 c is formed on theoutside part 3 b, and constitutes the pointed part of a part that is bent into substantially a shallow “V” shape toward themain sheet 1 at the lower end position of theoutside part 3 b. The shape of theoutside part 3 b from theoutside part 3 b to theengaging part 3 c is an inclined shape that is oriented downward and toward the outside. Furthermore, the system is arranged so that when the overlappingpart 3 is overlapped with theoverlapped part 2 in adjacent construction sheets A, A, theengaging part 3 c can be simultaneously engaged with theengaged part 2 c. - A plurality of the abovementioned construction sheets A are lined up side by side in the lateral direction. Then, as is shown in
FIG. 2E , thefastening part 4 of one adjacent construction sheet A is fastened to theunderlying part 5 viafastening fittings 12 such as screws or the like. The overlappingpart 3 of another construction sheet A is overlapped with theoverlapped part 2 of this first construction sheet A. In this case, themain sheet 1 in the vicinity of the overlappingpart 3 is placed on thefastening part 4 that is formed as a continuation of the abovementioned overlappedpart 2. In particular, in cases where a bent end edger 4 a is formed on the outer end of thefastening part 4, the back surface of themain sheet 1 of the adjacent construction sheet A contacts the top part of the abovementionedbent end edge 4 a. In this state, as is shown inFIG. 1B , the configuration can be arranged so that the head parts of thefastening fittings 12 such as screws or the like that fasten thefastening part 4 to theunderlying part 5 do not contact themain sheet 1. Furthermore, deformation of themain sheet 1 by accumulated snow can be prevented. - Resin welding is performed on the corner part K constituting the corner location of the
overlapped part 2 of one adjacent construction sheet A and the nearbymain sheet 1, as far as the vicinity of the lower part (lower end T) of theoutside part 3 b of the abovementioned overlappingpart 3. In concrete terms, the synthetic resin film m2 in the location of the corner part K of theoverlapped part 2 and the resin film m2 in the location of the lower end T of theoutside part 3 b of the overlappingpart 3 are fused (melted) by the performance of resin welding via the abovementionedresin welding member 8. In the resin welding work of fusion accomplished by means of thisresin welding member 8, a hot air blast is caused to strike an area centered on the abovementioned corner part K and lower end T as shown inFIG. 3C . As a result, in the resin welding work performed on the overlappedparts 2 and overlappingparts 3 of the construction sheets A, local thermal deformation caused by the hot air blast tends not to occur. - A running type resin welder B is used in the resin welding work. As is shown in
FIG. 3A , this running type resin welder B runs by means of car wheels, and a running motor is mounted in the body of this car. Furthermore, a weldingmember feeding apparatus 10 and a hotair draft apparatus 11 are mounted on this car body. A hot air draft is blown onto the location of theoverlapped part 2 and overlappingpart 3 from the spray nozzle 11 a of this hotair draft apparatus 11, and this location is filled with theresin welding member 8 from the abovementioned weldingmember feeding apparatus 10 while being heated to a high temperature. In this case, as is shown inFIG. 3B , the system is arranged so that the hot air draft from the spray nozzle 11 a strikes the corner part K of the abovementioned overlappedpart 2 and the lower end T of the overlappingpart 3, thus making it possible to fill the location of the corner part K and the location of the lower end T with the moltenresin welding member 8. Furthermore, theresin welding member 8 is fused with the respective synthetic resin films m2 of the abovementioned overlappedpart 2 and overlappingpart 3, so that theresin welding member 8 and synthetic resin films m2 are fastened into an integral unit, thus making it possible to form the overlapping area between theoverlapped part 2 and the overlappingpart 3 into a waterproof structure. - The blowing of a hot air draft is not necessarily required in this resin welding; however, some type of preheating is desirable in order to improve the welding capacity and welding quality. Furthermore, it would also be possible to use a manual type resin welder instead of the abovementioned running type resin welder. This manual type resin welder is a handy type welder that allows the worker to perform resin welding while holding the welder in his hand, and is constructed so that the welding
member feeding apparatus 10 and hotair draft apparatus 11 are substantially integrated. - Next, the trough structure that is mounted on the construction outer surrounding body of the present invention in cases where this construction outer surrounding body is worked as a roof will be described with reference to
FIGS. 7 and 8 . The mounting structure of this trough includes two types; first of all, in the first type, thetrough member 6 is constructed from a troughmain body 6 a and anattachment part 6 b. Thistrough member 6 is constructed from raw materials that are formed by constructing a thin metal sheet part m1 and a synthetic resin film m2 in layer form in the same manner as in the abovementioned construction sheet A. This troughmain body 6 has a substantially square cross-sectional shape, and anattachment part 6 b is integrally formed from the upper end of the side part of this troughmain body part 6 a. Furthermore, if at least the front surface of theattachment part 6 b of thetrough member 6 is covered with the abovementioned synthetic resin film m2, it is not absolutely necessary that the side of the troughmain body 6 a be covered with this synthetic resin film m2. In theattachment part 6 b, at the upper end of thisattachment part 6 b, a substantially horizontal bent part is formed so as to protrude outward in the lateral direction at the upper end of one side sheet in the lateral direction. - Furthermore, as is shown in
FIGS. 7 and 8 B, a hanging part la is formed on one end of the construction sheet A in the longitudinal direction on the part that constitutes the eave so that this hanging part la is substantially perpendicular to the longitudinal direction of themain sheet 1. This hanging part la is bent so that this part is oriented downward on the eave end of the abovementionedmain sheet 1 in the longitudinal direction, and forms substantially a right angle with the abovementionedmain sheet 1. Furthermore, the hanging part la may also form an angle that is inside or outside a right angle (but near a right angle) with respect to themain sheet 1; this hanging part need not be oriented at precisely a right angle. Anunderlying member 7 for use in welding is disposed in the connection location between the eave end of the construction sheet A and thetrough member 6. Like the abovementioned construction sheet A, this underlyingmember 7 for use in welding is also formed from a raw material in which a thin metal sheet part ml and a synthetic resin film m2 are constructed in layer form, thus facilitating resin welding of the construction sheet A andtrough member 6 as will be described later. However, it is not absolutely necessary that the raw material of the abovementioned underlyingmember 7 for use in welding be formed from a thin metal sheet part ml and a synthetic resin film m2. - As is shown in
FIGS. 7A and 7B , the cross-sectional shape of theunderlying member 7 for use in welding is a substantially step-form shape. In concrete terms, this is formed as a step-form shape with two steps, and is formed by appropriately bending a metal sheet member. This underlyingmember 7 for use in welding is a member that is long in the longitudinal direction, and is disposed so that this member is perpendicular to the longitudinal direction of the abovementioned construction sheet A. Furthermore, as is shown inFIGS. 7A and 7B , theattachment part 6 b of thetrough member 6 is disposed on thehorizontal surface 7 a 1 of thecentral corner part 7 a in a section perpendicular to the longitudinal direction of theunderlying member 7 for use in welding, so that the hanging part la of the construction sheet A contacts thevertical surface 7 a 2. - Furthermore, the
resin welding member 8 is also fused by resin welding to the synthetic resin film m2 of the abovementioned underlyingmember 7 for use in welding, so that the hanging part 1 a of the construction sheet A, theattachment part 6 b of thetrough member 6 and theunderlying member 7 for use in welding are fastened by being fused together. Furthermore, in the connection location of theoverlapped part 2 and overlappingpart 3 of the construction sheets A, A that are adjacent at the eave location, these parts are also fused (welded) by means of theresin welding member 8 to the portions of theoverlapped part 2 and overlappingpart 3 that are overlapped with the eave end, as shown inFIG. 7A . - As a result, the
resin welding member 8 can close off the opening part between theoverlapped part 2 and overlappingpart 3 at the eave in a water-tight manner by the fusion (welding) of thisresin welding member 8, so that this opening part is covered. In concrete terms, the area along the longitudinal direction of the overlapping location of the abovementioned overlappedpart 2 and overlappingpart 3 is fused (welded) by theresin welding member 8 to the corner part K and lower end T; furthermore, the overlapping tip end location of the abovementioned eave is sufficiently closed off by theresin welding member 8, and theresin welding member 8 is fused (welded) to the periphery of the eave on the opposite side from the abovementioned corner part K and lower end T. As a result, the water-tightness in the connection location between theoverlapped part 2 and overlappingpart 3 is secure. - Furthermore, the hanging part 1 a and
attachment part 6 b are fused (welded)by the abovementionedresin welding member 8. Moreover, theupper end surface 7 b on top of thecorner part 7 a of theunderlying member 7 for use in welding is placed on the top surface part of the abovementionedunderlying part 5, and the lower end surface 7 c in the lower part of theabovementioned corner part 7 a is in a state of contact with the vertical surface of the abovementionedunderlying part 5. Moreover, the troughmain body 6 a of theabovementioned trough member 6 may also be supported by abracket 9 fastened to theunderlying part 5 as shown inFIG. 7B . Thisbracket 9 is formed from a band-form metal sheet, and consists of afastening part 9 a that is fastened to the abovementionedunderlying part 5, and a supportingpart 9 b that supports theabovementioned trough member 6. Theabovementioned fastening part 9 a is fastened to the abovementioned underlying part by means of drill screws, anchor bolts or the like, and the supportingpart 9 provides support from the side of the undersurface of thetrough member 6. - Furthermore, a second type of trough structure is a trough structure which is continuously formed so that the
abovementioned trough member 6 andunderlying member 7 for use in welding constitute an integral unit as shown inFIGS. 8C and 8D . In this structure, in concrete terms, the location where theabovementioned attachment part 6 b was formed is changed to theunderlying member 7 for use in welding. This integrally formed underlyingmember 7 for use in welding is disposed on the abovementionedunderlying part 5 in more or less the same manner as in the abovementioned first type. Furthermore, a state is produced in which theupper end surface 7 b of the top location of theunderlying member 7 for use in welding is inserted between the construction sheet A and theunderlying part 5, and the abovementioned hanging part la and thehorizontal surface 7 a 1 of thecorner part 7 a of theunderlying member 7 for use in welding are fused (welded) via theresin welding member 8. -
FIG. 4A shows the second type of construction sheet A. As is shown inFIGS. 4B and 4C , this is a sheet in which the shapes of theoverlapped part 2 and overlappingpart 3 on both ends of themain sheet 1 in the lateral direction are formed substantially as inverted “U” shapes. Furthermore, afastening part 4 is formed as a continuation of theoverlapped part 2. Moreover, as in the case of the construction sheet A of the abovementioned first type, theoverlapped part 2 comprises aninside part 2 a and anoutside part 2 b, and the overlappingpart 3 also comprises aninside part 3 a and outsidepart 3 b. - In the lower part of the
inside part 2 a of theoverlapped part 2, anengaged part 2 c is formed so that this engaged part is recessed inside the abovementioned overlappedpart 2 formed with an inverted “U” shape. Similarly, theengaging part 3 c from the lower end of theoutside part 3 b so that this engaging part is recessed into a shallow “V” shape toward the inside of the overlappingpart 3 formed with an inverted “U” shape. This second type is devised so that the engaged state is slightly shallower than that of theengaged part 2 c andengaging part 3 c of the abovementioned first type, thus making it possible to reduce the pressing force required in the engagement work. Furthermore, thefastening part 4 is continuously formed from the lower end of theoutside part 2 b of the abovementioned overlappedpart 2. -
FIG. 5A shows a third type of construction sheet A. As is shown inFIGS. 5B and 5C , this is a sheet the shapes of theengaged part 2 c of theoverlapped part 2 and theengaging part 3 c of the overlappingpart 3 are not formed. Specifically, in this sheet, the overlappingpart 3 is merely overlapped with theoverlapped part 2, and the synthetic resin films m2, m2 are then fused to each other using only theresin welding member 8. In this third type of construction sheet A, as in the first and second types, theoverlapped part 2 comprises aninside part 2 a and anoutside part 2 b, and the overlappingpart 3 also comprises aninside part 3 a and anoutside part 3 b. Furthermore, theabovementioned fastening part 4 is continuously formed from the lower end of theoutside part 2 b of the abovementioned overlappedpart 2. -
FIG. 6A shows a fourth type of construction sheet A. As is shown inFIGS. 6B and 6C , this sheet is construction from a construction sheet A and asuspension element 6′. In this construction sheet A, anoverlapped part 2 and an overlappingpart 3 are respectively formed on both sides of amain sheet 1 in the lateral direction. Furthermore, as described above, themain sheet 1, overlappedpart 2 and overlappingpart 3 are covered by a synthetic resin film m2. Theoverlapped part 2 is formed in the shape of a vertical sheet, and the overlappingpart 3 consists of aninside part 3 a and anoutside part 3 b; the cross section is formed substantially in an inverted “U” shape by thisinside part 3 a and outsidepart 3 b. - Furthermore, as is shown in
FIG. 6B , thesuspension element 6′ is constructed from afastening base part 6 a′ and a retainingpart 6 b′, and this retainingpart 6 b′ is formed with a cross section that has substantially an inverted “U” shape. Moreover, theoverlapped part 2 of the construction sheet A is fastened by the retainingpart 6 b′ of theabovementioned suspension element 6′, through-holes 6 a 1′ are bored in thefastening base part 6 a′ of thesuspension element 6′, andfastening fittings 12 such as screws or the like are passed through the through-holes 6 a 1′ and fastened to theunderlying part 5. Furthermore, the overlappingpart 3 is overlapped with theoverlapped part 2, and resin welding is performed on themain sheet 1 in the vicinity of the corner part K, and as far as the vicinity of the lower part (lower end T) of the abovementioned overlappingpart 3. - Furthermore, in cases where the construction outer surrounding body is worked as a roof, there may be instances, as shown in
FIG. 7A , in which risingmembers 13 are disposed on the horizontal upper ends of the lined-up construction sheets A, A, . . . In such a case, the joint structure of the abovementioned risingmembers 13 has a configuration in which the horizontal upper ends of the areas of overlapping between theoverlapped parts 2 and overlappingparts 3 are in close proximity or substantially in a state of contact with the abovementioned risingmembers 13, and the corner locations formed by the overlappedparts 2, overlappingparts 3 and risingmembers 13 are fused by performing resin welding via the abovementionedresin welding member 8. - Furthermore, like the construction sheets A, the abovementioned rising
members 13 are formed by a thin metal sheet part m1 and a synthetic resin film m2 disposed in layer form; naturally, the synthetic resin film m2 faces the horizontal upper sides of the abovementioned overlappedparts 2 and overlappingparts 3. Furthermore, the synthetic resin film m2 of the risingmembers 13 and the synthetic resin film m2 of the overlappedparts 2 and overlappingparts 3 are fused via theresin welding member 8, thus making it possible to form a secure waterproof structure. The risingmember 13 are used as wall surfaces or the like formed on the end parts of the horizontal upper side of the roof. - Furthermore, as was described above, it is desirable that the construction sheets A,
trough members 6 andunderlying parts 7 for use in welding be used with the synthetic resin film m2 positioned on the top surface side so that mutual fusion (welding) is facilitated. Specifically, in the joints between adjacent construction sheets A, A, the system is arranged so that the synthetic resin film m2 is positioned on the top surface sides of the overlappedparts 2 and overlappingparts 3; the synthetic resin film m2 is positioned on the top surface sides of the construction sheets A,trough members 6 andunderlying parts 7 for use in welding so that these respective members are easily fused. - As is shown in
FIG. 2 , the construction sheets A are formed from a raw material in which a thin metal sheet m1 and a synthetic resin film m2 are constructed in layer form, and each of these construction sheets A consists of amain sheet 1, anoverlapped part 2 which is formed on one end of thismain sheet 1 in the lateral direction, an overlappingpart 3 which is formed on the other end of the abovementionedmain sheet 1 in the lateral direction, and which can overlap with the abovementioned overlappedpart 2, and afastening part 4 which is formed in a substantially flat shape from the outside end of the abovementioned overlappedpart 2. - A plurality of construction sheets A, A, . . . are lined up side by side on an
underlying part 5. As is shown inFIG. 2E , thefastening part 4 of one adjacent construction sheet A is fastened to theunderlying part 5 by means offastening fittings 12 such as drill screws or the like, a portion of themain sheet 1 near the overlappingpart 3 of another adjacent construction sheet A is placed on thisfastening part 4, and the overlappingpart 3 is overlapped with the abovementioned overlappedpart 2. Then, as is shown inFIG. 3C , resin welding is performed via theresin welding member 8 from the vicinity of the outsides (lower ends T) of the overlappingparts 3 of both adjacent construction sheets A, A to the vicinity of the inside corner parts (corner parts K) of the overlappedparts 2, so that the abno synthetic resin films m2, m2 of the adjacent construction sheets A, A are fused together with theresin welding member 8, and an outer surrounding body such as a roof, wall or the like is formed. - In the construction outer surrounding body of the present invention, as was described above, each construction sheet A has a thin metal sheet part m1 and a synthetic resin film m2 that are constructed in layer form; furthermore, each of these construction sheets A has a
main sheet 1, anoverlapped part 2 which is formed on one end of thismain sheet 1 in the lateral direction, an overlappingpart 3 which is formed on the other end of the abovementionedmain sheet 1 in the lateral direction, and which can overlap with the abovementioned overlappedpart 2, and afastening part 4 which is formed in a substantially flat shape from the outside end of the abovementioned overlappedpart 2. - Furthermore, the area in the vicinity of the overlapping
part 3 of one adjacent construction sheet A is placed on thefastening part 4 of another adjacent construction sheet A, the overlappingpart 3 is overlapped with the abovementioned overlappedpart 2, and the synthetic resin films m2, m2 of the adjacent construction sheets A, A can be fused (resin-welded) and connected via theresin welding member 8 from the vicinity of the outer ends of the overlappingparts 3 of both construction sheets A, A to the vicinity of the inside corner parts of the overlappedparts 2, so that the work is extremely efficient, and can be performed quickly and easily. Furthermore, since the synthetic resin films m2, m2 of the adjacent construction sheets A, A are fused (welded) to each other by means of theresin welding member 8, a body with extremely good waterproofing and water-tightness can be obtained. - Furthermore, as was described above, since the
abovementioned fastening part 4 is continuously formed from the outside end of theoverlapped part 2, the fastening of thisfastening part 4 to theunderlying part 5 or the like by means offastening fittings 12 such as drill screws or the like can easily be accomplished, and since thisfastening part 4 is also covered and hidden by a portion of themain sheet 1 near the overlappingpart 3 of the other adjacent construction sheet A, an extremely clean state can be obtained in terms of external appearance. As a result, mounting members such as suspension elements or the like become unnecessary on the construction sheets A, so that the number of parts required can be greatly reduced. - Furthermore, the adjacent construction sheets A, A are connected by fusion of the synthetic resin films m2, m2 via the
resin welding member 8; here, since theresin welding member 8 and synthetic resin films m2 are both synthetic resins, these parts will melt at a low temperature, so that a high temperature that would cause deformation due to local thermal strain in a metal is unnecessary. Accordingly, the constructions sheets A themselves can be given a good finish with no occurrence of deformation caused by thermal strain. - Furthermore, as a result of the fact that [i] an
engaged part 2 c is formed in the abovementioned overlappedpart 2, [ii] anengaging part 3 c is formed in the overlappingpart 3 in a position corresponding to the abovementioned engagedpart 2 c, and [iii] the abovementioned engagedpart 2 c andengaging part 3 c are engaged and fastened, the working efficiency can be improved. - Specifically, by engaging the abovementioned engaged
part 2 c andengaging part 3 c until the fusion of the synthetic resin films m2, m2 to each other by resin welding via theresin welding member 8 in the lined-up construction sheets A, A, . . . is completed, it is possible to maintain the overlapped state of the overlappedparts 2 and overlappingparts 3, so that stability of positioning and of the working operation can be obtained. As a result, safe work can be performed extremely accurately and efficiently. Furthermore, as a result of the formation of the overlappedparts 2 and engagingparts 3 c, the following advantage is also obtained: namely, the cross-sectional strength of the area of overlapping between theoverlapped parts 2 and overlappingparts 3 can be improved. - Furthermore, as a result of a construction surrounding body being constructed in which the eave locations on the end parts of the abovementioned construction sheets A in the longitudinal direction and a
trough member 6 formed by constructing a thin metal sheet part ml and a synthetic resin film m2 in layer form are fused by the abovementioned synthetic resin film m2 via the abovementionedresin welding member 8, the water-tight mounting of the eave andtrough members 6 in the longitudinal direction of the construction sheets A, A, . . . can be greatly simplified. - Specifically, like the construction sheets A, the
abovementioned trough member 6 is also a member in which a thin metal sheet part m1 and a synthetic resin film m2 are constructed in layer form, and the eave end parts of the abovementioned construction sheets A and therespective trough members 6 can be fused (welded) by resin welding via theresin welding member 8. As a result, the spaces between the eave end parts in the longitudinal direction of the construction sheets A and thetrough members 6 are completely water-tight, so that rain water can be securely introduced into thetrough members 6. - Next, the manufacturing apparatus B will be described. As is shown in
FIGS. 9A and 9B , this manufacturing apparatus B is constructed mainly from a resin welder part B1 consisting of a weldingmember feeding apparatus 10 and a hotair draft apparatus 11, awelder receiving stand 21 that supports this welder part B1, a drivingpart 16, a runningpart 17, a finishingroll part 20, acar part 19 and the like. Thiscar part 19 is formed in a rectangular flat plate shape. The abovementioned resin welder part B1, drivingpart 16 and the like are mounted on the upper surface of thecar part 19; furthermore, the runningpart 17 is mounted on the undersurface side of thecar part 19. - As is shown in
FIG. 10B andFIGS. 11A and 11B , the abovementioned runningpart 17 is constructed from runningwheels 17 a and axles 17 b that are used to cause thecar part 19 to run; theseaxles 17 b are mounted via bearings on the undersurface of theabovementioned car part 19 in locations on both ends in the forward-rearward direction, and the runningwheels 17 a are mounted on theseaxles 17 b. As is shown inFIG. 9 and 10, the runningwheels 17 a consist offront wheel parts 17 a 1 andrear wheel parts 17 a 2. - The respective
front wheel parts 17 a 1 andrear wheel parts 17 a 2 of the runningpart 17 are rotationally driven via the abovementioned drivingpart 16. As is shown inFIG. 9B , this drivingpart 16 consists of a drivingmotor 16 a and atransmission part 16 b, and a chain or the like is used as thetransmission part 16 b. Furthermore,transmission receiving parts 17 c such as driven sprockets or the like are mounted on therespective axles front wheel parts 17 a 1 andrear wheel parts 17 a 2, and atransmission part 16 b such as a chain or the like is mounted between a drivingmember 16 c such as a driving sprocket or the like mounted on theabovementioned driving motor 16 a, and the abovementionedtransmission receiving parts 17 c, so that a rotational force is transmitted to thefront wheel parts 17 a 1 andrear wheel parts 17 a 2 from the drivingpart 16. - In this way, the system is arranged so that the
front wheel parts 17 a 1 andrear wheel parts 17 a 2 can be caused to rotate independently in the same direction by the via the drivingpart 16. The constructions of this drivingpart 16 and runningpart 17 are not limited to the constructions described above. In order to obtain a structure that supports the weight of these apparatuses, theabovementioned car part 19 has the strength of a relatively thick part; in actuality, metal plate or the like are used. Furthermore, besides the abovementioned independent driving system for thefront wheel parts 17 a 1 andrear wheel parts 17 a 2, it would also be possible to use a driving system involving thefront wheel parts 17 a 1 alone or a driving system involving therear wheel parts 17 a 2 alone. - Next, as is shown in
FIGS. 9A and 9B , the resin welder part B1 is constructed from a weldingmember feeding apparatus 10 and a hotair draft apparatus 11 as described above. This weldingmember feeding apparatus 10 has the function of feeding out the moltenresin welding member 8 to specified locations, and is an apparatus in which a feed-outpart 10 b is disposed on the tip end of aholder 10 a. Aresin welding member 8 is accommodated inside thisholder 10 a; theresin welding member 8 is carried to the location of the feed-outpart 10 b, and thisresin welding member 8 is extruded from this feed-outpart 10 b, so that resin welding is performed in specified locations while theresin welding member 8 is heated by a hot air draft sprayed from the spray nozzle 11 a of the abovementioned hotair draft apparatus 11. - The resin welder part B1 is supported on a
welder receiving stand 21 mounted on thecar part 19. Furthermore, as is shown inFIGS. 9 and 10 , the resin welder part B1 is connected to thewelder receiving stand 21 by means of a pivot-supporting connectingmember 22 so that the resin welder part B1 is free to pivot on the vertical plane with respect to thewelder receiving stand 21, thus allowing this resin welder part B1 to be freely set in an appropriate manner in vertical and horizontal positions. In the abovementioned pivot-supporting connectingpart 22, the resin welder part B1 and thewelder receiving stand 21 are connected via a shaft or the like so that these parts are free to pivost. A mechanism may also be provided which is devised so that when the abovementioned resin welder part B1 is caused to pivot with respect to thewelder receiving stand 21, an appropriate resistance force is generated against the force that causes the pivoting motion so that stabilized operating characteristics are obtained. - Furthermore, during the resin welding operation, the abovementioned resin welder part B1 is set in a substantially vertical state. Furthermore, the resin welder part B1 can be freely raised or lowered with respect to the
welder receiving stand 21, so that the height position of the spray nozzle 11 a of the hotair draft apparatus 11 can be adjusted, thus making it possible to set the position of the spray nozzle 11 a at a desired height as shown inFIG. 10A . Thewelder receiving stand 21 is mounted on theabovementioned car part 19. Furthermore, when the manufacturing apparatus B is not being used, or prior to the initiation of the resin welding operation or the like, the resin welder part B1 can be set in a horizontal state as shown inFIG. 10B . - As a result, important locations such as the location of the spray nozzle 11 a of the resin welder part B1 and the like can be protected. Furthermore, even when the manufacturing apparatus B is disposed in the working location, the
car part 19 can easily be disposed in a specified position by placing the resin welder part B1 in a horizontal state. Then, efficient planning work can be accomplished by setting the resin welder part B1 in a vertical state after it has been confirmed that thecar part 19 has been disposed in an accurate position, and performing a fine adjustment of the height of the spray nozzle 11 a. - As is shown in
FIGS. 12A through 12C ,FIG. 13 and the like, a feed-outnozzle 10 c is mounted in the feed-outpart 10 b of the weldingmember feeding apparatus 10. As is shown inFIG. 12A , the feed-outpart 10 b has a block shape, and is formed substantially in the shape of a triangular prism. A feed-outpart opening 10 b 2 is formed in theinclined surface part 10 b 1. A feed-outnozzle 10 c (described later) is disposed on theinclined surface part 10 b 1, and, as is shown inFIG. 13A , when the resin welder part B1 is set in a state that allows welding operations, this nozzle substantially faces the locations of the corner parts K in the connection locations between the overlappingparts 3 and overlappedparts 2 of the construction sheets A, A (described later). - Furthermore, the corner parts K in the connection locations (hereafter referred to as “connecting parts”) of the adjacent construction sheets A, A are filled with the
resin welding member 8, and the surface of the resin welding is finished with themolding surface 10 c 1 in a well-ordered state. The feed-outnozzle 10 c is connected to thisinclined surface part 10 b 1. This feed-outnozzle 10 c is formed with a substantially triangular cross-sectional shape, and amolding surface 10 c 1 and a resin jet opening 10 c 2 are formed on the tip end portion of this feed-outnozzle 10 c. Thismolding surface 10 c 1 presses against theresin welding member 8 that jets from the abovementioned resin jet opening 10 c 2 and is caused to fill the connection location between the abovementioned overlappingpart 3 and overlappedpart 2; themolding surface 10 c 1 cleanly molds the surface of theresin welding member 8 with the movement of theabovementioned car part 19, and has the function of adjusting this surface. - As is shown in
FIG. 12A andFIG. 13 , themolding surface 10 c 1 has a polyhedral shape. In concrete terms, this molding surface consists of three flat surfaces; a resin jet opening 10 c 2 is formed in the central surface, and the system is arranged so that theresin welding member 8 that is caused to jet in a molten state from the resin jet opening 10 c 2 is pressed against the connection location between the abovementioned overlappingpart 3 and overlappedpart 2 by themolding surface 10 c 1, and is thus molded into a flat surface so that a good finished surface is obtained. - In cases where the
molding surface 10 c 1 is formed as a part consisting of three surfaces, the central surface has the role of adjusting the surface of theresin welding member 8 that is melted and caused to fill the locations of the corner part K of the abovementioned overlappedpart 2 and the lower end T of the overlappingpart 3 so that an inclined surface is formed as shown inFIG. 13A . Furthermore, the surface that is adjacent to the central surface of theabovementioned molding surface 10 c 1 on the upper side molds the moltenresin welding member 8 so that a surface that is substantially perpendicular with respect to the locations of the corner part K of the abovementioned overlappedpart 2 and lower end T of the overlappingpart 3 is obtained, while the surface that is adjacent to central surface on the lower side has the role of pressing the moltenresin welding member 8 so that a surface that is substantially parallel to themain sheet 1 of the abovementioned construction sheet A is obtained. - As is shown in
FIG. 14A , themolding surface 10 c 1 may also be formed as a circular arc form surface. Furthermore, in cases where themolding surface 10 c 1 is formed as a circular arc form surface, the finished surface of the moltenresin welding member 8 is a circular arc form surface as shown inFIG. 14B . These various types of molding surfaces 10 c 1 may also be subjected to Teflon (registered trademark) working, so that the moltenresin welding member 8 tends not to adhere to the molding surfaces. This feed-outnozzle 10 c is freely detachable with respect to the abovementioned feed-outpart 10 b, and is fastened by means of fastening fittings such as screws, bolts or the like. - As is shown in
FIGS. 12B, 12C and 13, apressing part 18 is mounted on the abovementioned feed-outpart 10 b if necessary. Thispressing part 18 presses one of the adjacent construction sheets A against theunderlying part 5 in case where resin welding is performed in the corner parts K in the connecting parts j of the abovementioned adjacent construction sheets A, A, and thus prevents a deviation in the position of the construction sheet A in the resin welding work. In thispressing part 18, apressing roll 18 b is mounted on apressing frame 18 a. Thispressing frame 18 a is detachably mounted on the feed-outpart 10 b by means of fastening fittings such as screws, bolts or the like. Furthermore, thepressing roll 18 b presses themain sheet 1 of the abovementioned construction sheet A. Thepressing frame 18 a is formed in an “L” shape as shown inFIG. 13B (which shows the pressing frame in a plan view). - Furthermore, the abovementioned feed-out
nozzle 10 c is mounted on thecar part 19 via awelder receiving stand 21. The resin welder part B1 is mounted on thewelder receiving stand 21 so that the height of this resin welder part can be adjusted in the vertical direction. Thecar part 19 is formed in a flat plate form in the longitudinal direction, and can be caused to run by means of the drivingpart 16 and runningpart 17. A hot air draft in blown onto the locations of the overlappedparts 2 and overlappingparts 3 from the spray nozzle 11 a of the hotair draft apparatus 11, and these locations are filled with theresin welding member 8 from the abovementioned weldingmember feeding apparatus 10 while being heated to a high temperature (seeFIG. 13A ). - In this case, as is shown in
FIG. 13A , the system is arranged so that the hot air draft from the spray nozzle 11 a strikes the corner parts K of the abovementioned overlappedparts 2 and the lower ends T of the overlappingparts 3, so that the moltenresin welding member 8 can fill the locations of the corner parts K and the locations of the lower ends T. Furthermore, theresin welding member 8 fuses with the respective synthetic resin films m2 of the abovementioned overlappedparts 2 and overlappingparts 3, so that theresin welding member 8 and the synthetic resin films m2 are fastened into an integral unit, thus making it possible to form the location of the overlapping area between theoverlapped parts 2 and overlappingparts 3 into a waterproof structure. - Furthermore, as is shown I
FIGS. 10B, 15A and the like, a finishingroll part 20 equipped with a tighteningroll 20 a and a supportingroll 20 b is mounted on the undersurface side of thecar part 19. As is shown inFIGS. 15B and 15C , the abovementioned finishing rollpart 20 tightens the overlappedparts 2 and overlappingparts 3 of the adjacent construction sheets A, A; the abovementioned tightening roll 20 a supports theoutside part 3 b of the overlappingpart 3, and the supportingroll 20 b presses against theinside part 3 a. - The tightening
roll 20 a and supportingroll 20 b are driven by anelastic member 20 d and guideshaft 20 e so that these parts approach each other. Furthermore, the supportingroll 20 b can be forcibly separated from the abovementioned tightening roll 20 a by means of an operatingknob part 20 c. This tighteningroll 20 a and supportingroll 20 b perform connection work between the overlappingparts 3 and overlappedparts 2, and also play a role in stabilizing the running of thecar part 19. Furthermore, in regard to the tightening structure in the connecting parts j, there may also be cases in which the abovementioned tightening roll 20 a supports theinside parts 3 a of the overlappingparts 3, and the supportingroll 20 b presses against theoutside parts 3 b. - Furthermore, as is shown in
FIGS. 15A, 15B and 15C, guide rings 23, 23 are disposed on thecar part 19 in locations on both ends in the forward-rearward direction adjacent to the abovementioned supportingroll 20 b. These guide rings 23, 23 rotate while being carried on the top parts of the connecting parts j between theoverlapped parts 2 and overlappingparts 3 of the adjacent construction sheets A, A, and have a pulley shape in which the diameter is reduced in the center in the lateral direction (direction of thickness). Thecar part 19 can be caused to move accurately along the connecting parts j by these guide rings 23, 23. Furthermore, the guide rings 23 may also be formed with a structure in which bearings allow free movement in the horizontal direction. - Next, the performance of resin welding by the manufacturing apparatus B will be described. First, the abovementioned construction sheets A, A, . . . are placed on the
underlying part 5, and the overlappedparts 2 and overlappingparts 3 of the adjacent construction sheets A, A are overlapped and connected. The guide rings 23, 23 mounted on both ends of the abovementioned manufacturing apparatus B in the forward-rearward direction are disposed in the abovementioned connection location, and thefront wheel parts 17 a 1 andrear wheel parts 17 a 2 are disposed on themain sheet 1 of the construction sheet A (seeFIG. 9A ). Next, the drivingpart 16 is started so that thefront wheel parts 17 a 1 andrear wheel parts 17 a 2 are caused to rotate, thus causing the manufacturing apparatus B to run, and resin welding is performed in the abovementioned overlapped connection location by the resin welder part B1 mounted in the manufacturing apparatus B. - This manufacturing apparatus B can be caused to move along the longitudinal direction of the connecting parts j between the
overlapped parts 2 and overlappingparts 3 by the abovementioned guide rings 23, 23, so that resin welding can be performed in a favorable state in these connecting parts j, thus making it possible to obtain a uniform finish in the welded surface (seeFIG. 13A ). - In the manufacturing apparatus B of the present invention, the
car part 19 on which the resin welder part B1 is mounted runs via the drivingpart 16 and runningpart 17; as a result, merely by setting the position where the resin welder part B1 is to fill the connection locations (connecting parts j) between the abovementioned adjacent construction sheets A, A with the moltenresin welding member 8, it is possible to achieve substantially accurate and uniform filling with the moltenresin welding member 8 by the running of thecar part 19, so that the finish can also be made extremely clean. This finish is substantially the same as that obtained by an experienced worker. - Furthermore, in the apparatus of the present invention, as a result of the provision of a resin welder part B1 constructed from a
car part 19 equipped with a runningpart 17 that is caused to rotate by the abovementioned drivingpart 16, a weldingmember feeding apparatus 10 that feeds out the moltenresin welding member 8, and a hotair draft apparatus 11 that heats the connection locations (connecting parts j) between the abovementioned adjacent construction sheets A, A, favorable resin welding can be performed in the connection locations (connecting parts j) between the adjacent construction sheets A, A, so that these connection locations can be formed as parts that have more secure water-tightness and air-tightness. - Specifically, in the manufacturing apparatus B of the present invention, the synthetic resin film m2 in the connection locations (connecting parts j) between the adjacent construction sheets A, A is melting by the hot
air draft apparatus 11, and theresin welding member 8 that is extruded from the weldingmember feeding apparatus 10 is integrally mixed with the abovementioned melted synthetic resin film m2; as a result, more secure water-tightness and air-tightness can be obtained. Furthermore, the manufacturing apparatus B of the present invention has a structure in which thecar part 19 runs by means of a drivingpart 16 and a runningpart 17, and comprises a weldingmember feeding apparatus 10 that feeds out theresin welding member 8, and a hotair draft apparatus 11 that heats the connection locations (connecting parts j) between the adjacent construction sheets A, A, on theabovementioned car part 19. - Moreover, since resin welding is performed while the manufacturing apparatus B is caused to run by the abovementioned driving
part 16 and runningpart 17, the finish of the resin welding along the running direction can be made uniform, so that an extremely good finish can be obtained. Furthermore, since the abovementionedresin welding member 8 and synthetic resin film m2 are both synthetic resins, these materials can be melted at a relatively low temperature, so that the following advantage is also obtained: namely, a good finish can be obtained without causing any deformation due to thermal strain in the constructions sheets A themselves. - Furthermore, by mounting a connecting roll part comprising a tightening
roll 20 a that tightens the connection locations of the adjacent construction sheets A, A, and a supportingroll 20 b, on theabovementioned car part 19, it is possible to fill the connection locations between the adjacent construction sheets A, A with the moltenresin welding member 8 while tightening these connection locations, so that a good finish can be obtained. Specifically, the abovementioned connectingroll part 20 comprises a tighteningroll 20 a and a supportingroll 20 b, and thecar part 19 moves while the abovementioned connection location (overlapping connection location between theoverlapped parts 2 and overlapping parts 3) is tightened by this tighteningroll 20 a and supportingroll 20 b. As a result, the connecting locations (connecting parts j) between theoverlapped parts 2 and overlappingparts 3 of the adjacent construction sheets A, A are filled with the moltenresin welding member 8 while these connection locations are tightened, so that resin welding can be performed in a much more favorable state. - Furthermore, in the apparatus of the present invention, if guide rings 23, 23 that are placed on the top parts of the connection locations between construction sheets A, A that are adjacent in the forward-rearward direction are disposed on the
abovementioned car part 19, the manufacturing apparatus B can be caused to move accurately along the connection locations (connecting parts j) between the adjacent construction sheets A, A, so that the filling with the moltenresin welding member 8 is much more accurate, thus making it possible to obtain a good finish. Here, guide rings 23, 23 are disposed in the forward-rearward direction of thecar part 19, and these guide rings 23, 23 are disposed in the connection locations (connecting parts j) between the adjacent construction sheets A, A, so that the connection locations (connecting parts j) between the abovementioned construction sheets A, A act as rails. As a result, the manufacturing apparatus B can be caused to move accurately along the connection locations (connecting parts j), so that the resin welding can be cleanly and uniformly adjusted, thus making it possible to obtain a uniform finish. - Furthermore, in the apparatus of the present invention, the abovementioned resin welder part B1 can be freely set in an appropriate position along the vertical direction, so that the planning of the resin welding work performed by the manufacturing apparatus B can be carried out with good efficiency. Specifically, the abovementioned resin welder part B1 can be freely set in an appropriate position along the vertical direction. As a result, an extremely accurate position can be filled with the molten
resin welding member 8 by first setting the resin welder part B1 in a high position, and then lowering the abovementioned resin welder part B1 to the appropriate position following fine adjustment of the position of the car part 19 (without causing the tip end locations of the weldingmember feeding apparatus 10 and hotair draft apparatus 11 to contact the connection location) when the manufacturing apparatus B is disposed in the connection location between the abovementioned adjacent construction sheets A, A, and performing resin welding. - Furthermore, in the apparatus of the present invention, since a feed-out nozzle 10C that feeds out the abovementioned
resin welding member 8 to the connection location (connecting part j) between the abovementioned adjacent construction sheets A, A is mounted in the weldingmember feeding apparatus 10 of the abovementioned resin welder part B1, and amolding surface 10 c 1 is formed in this feed-outnozzle 10 c, the surface of the resin welding can be adjusted to a uniform surface. - Specifically, the
resin welding member 8 in a molten state that is extruded from the feed-outnozzle 10 c fills the connection location (connecting part j) between the abovementioned adjacent construction sheets A, A, and the connection location (connecting part j) is at the same time pressed by themolding surface 10 c 1, so that the surface of the resin welding is uniform; furthermore, since themolding surface 10 c 1 moves in the longitudinal direction of the connection location (connecting part j) as thecar part 19 moves, the surface of theresin welding member 8 that fills the connection location (connecting part j) can be formed with a flat, uniform surface state. - Furthermore, in the apparatus of the present invention, since a
pressing part 18 that presses themain sheets 1 in the vicinity of the connection location between the adjacent construction sheets A, A is mounted in the feed-outpart 10 b of the abovementioned weldingmember feeding apparatus 10, themain sheets 1 in the vicinity of the connection location between the adjacent construction sheets A, A can be pressed by thispressing part 18, so that the area in the vicinity of the connection location (connecting part j) between the adjacent construction sheets A, A can be stabilized in the resin welding work, thus tending to prevent deviation in the vertical direction from being generated in the adjacent construction sheets A, A, so that resin welding with an extremely good finish can be performed. - Furthermore, since the areas in the vicinity of the connecting parts j of the
main sheets 1 are pressed by thepressing part 18, any steps that might be created in the vicinity of the connecting parts j of themain sheets 1 can be eliminated or reduced before these steps are subjected to resin welding, so that favorable resin welding can be performed. Furthermore, even in cases where field sheets or the like are in a non-uniform state, good running of the apparatus can be maintained by means of thepressing part 18. - Furthermore, in the apparatus of the present invention, the running
wheels 17 a of the abovementioned runningpart 17 consist offront wheel parts 17 a 1 andrear wheel parts 17 a 2, and a construction outer surrounding body manufacturing apparatus is constructed in which both the abovementionedfront wheel parts 17 a 1 andrear wheel parts 17 a 2 are rotationally driven by the abovementioned drivingpart 16; accordingly, the resin welding can be given a favorable finish. Specifically, the manufacturing apparatus B is an apparatus in which thefront wheel parts 17 a 1 andrear wheel parts 17 a 2 of the runningwheels 17 a are independently driven, so that stable and accurate running can be accomplished. - Furthermore, the movement speed of the resin welding member feed-out
nozzle 10 c is also a constant and stable speed, so that amount of filling with the fed-outresin welding member 8 can be made uniform in all positions. Accordingly, the resin welding can be given a good finish. Moreover, even if themain sheets 1 of the construction sheets A do not have a flat surface, but are rather surfaces with some indentations and projections, or surfaces that are in an irregular state with respect to the running direction, the effects of these indentations and projections or irregularities can be avoided, so that running at a stable constant speed can be maintained, since thefront wheel parts 17 a 1 andrear wheel parts 17 a 2 of the runningwheels 17 a are driven independently. - The present invention can be utilized in outer surrounding bodies such as roofs, walls or the like worked as construction sheets in which the surface or a thin metal sheet is covered by a film made of a synthetic resin. In particular, good waterproofing and water-tightness can be obtained in the connection locations between construction sheets, and in the mounting locations of members such as trough members, and an extremely favorable finish and working characteristics can be obtained. Moreover, the manufacturing apparatus of the present invention makes it possible to obtain an extremely good finish in terms of waterproofing and water-tightness regardless of the experience of the worker.
