Description

  This invention is a building board formed of metal widely used in factories, warehouses, gymnasiums, supermarkets, other facilities, etc., and the main structure consists of a valley, a mountain, a support, and a fixed part. The present invention relates to a mating-type building board and its structure that can be used to easily and safely lay roofs and walls.

Conventionally, as a method of roof roof, the roof-shaped roof material connected at the top of the mountain is fixed to the base with hanging pieces hanging from the lower roof (male) at a fixed interval, and the upper roof (female)馳) was tightened with a multiple clamping machine.

JP-A-2-108753 JP-A-6-294182

In the case of such a roofing material, in Patent Document 1, in tightening the hook part to be connected, the hook part is arranged on the top, and the upper female hook part and the lower male hook part are connected using a tightening machine. , The rising side piece 6a and the inclined bent piece 6b of the upper heel (female) of FIG. 13 are pressed, and in this pressing process, the locking pieces 6c and 6d are also pressed and pressed together to perform clamping. The same applies to 7a and 7b in FIG. A clamping machine was used to crimp the four plates. For this reason, labor was required for the tightening work, press adjustment, and management of the machine.
In this connection locking method, the upper collars 6a, 6b and the lower collar 4b are clamped from the horizontal direction by a clamping machine, and at the same time, 6d moves along the top 3, and deforms while crushing 6c. It is a complicated shape that is locked to For this reason, it has the subject that it will be hard to fit unless mutual deformation | transformation deform | transforms with a sufficient balance. Further, since 6d moves along the surface of the top portion 3, there is a problem that the finished painted surface is damaged.
Next, in the formability of the heel part, the lower heel part is shaped so that each side of 4, 4a, 4b is folded and overlapped by overlapping two plates. The upper collar 6 also has a bowl shape with short sides and small gaps. This saddle-shaped molding is a shape that is very difficult to obtain dimensional accuracy, and has a big problem with accurately molding the collar portion.

Furthermore, in the influence of the strength on the locking part, because the form of connecting the locking part is a fitting on one side only, when a strong wind of negative pressure comes to the non-fitting side, the valley plate and the hypotenuse rise, Stress to peel off is applied. Therefore, there is a problem that resistance is weak in strong winds, one side always floats, floats and sinks in strong and strong winds and typhoons, and squeaks metal plates and causes metal fatigue.
In addition, due to the strength of the locking part, because the locking part is placed at the top of the mountain, it is located far from the valley plate, and the rotational moment of the buoyancy of the valley plate due to negative pressure during strong winds is large, and a strong fitting Was needed.
Further, in terms of strength, the top 3 forming the mountain was formed of a single plate, and the strength of the mountain was set with a single plate.

  Next, because the hanging piece that supports the mountain and the hypotenuse stands vertically, if a load is applied to the mountain, it does not know whether buckling or falling will fall to the left or right, and it will break due to deformation or strength However, there was anxiety.

  In addition, in the design after being rolled up, in the valley where the surface can be seen during use, the valley that touches the base material bites into the base material due to the load during construction, material transportation, and snow load, The width of the material was transferred to the surface at an interval of the base material, and there was an unsightly defect.

  Furthermore, in terms of the waterproofness of the mounting portion, since the bottom of the mounting portion is flat, when a hole is drilled and fixed, intruded rain water or condensed water may leak into the room from the screw hole. Moreover, since the mounting portion is flat, there is no spring washer function when tightening the fixed screw, so there was a concern that the screw would loosen over time.

  Further, since the folded piece at the outer end portion of the attachment portion is not used for hanging, the utility value is increased, and a fence or a ceiling material is attached.

On the other hand, in patent document 2, the collar part which connects the folding plate for roofs is arrange | positioned at the peak part of a mountain, and is comprised by the trough part including the hypotenuse part formed in connection with it, a fall piece, and a collar part. The challenges are as follows. The heel part is a fitting type of male heel 5 and female heel 4, but when using a steel springback property with a small shape, a large force is required by human power when using the normally used 0.6 to 1 mm In order to cope with the pressing force of human power, a tightening machine is used or the engagement is reduced and the engagement force is reduced. In addition, when it tightens strongly with a clamping machine, the problem similar to patent document 1 generate | occur | produces. However, this small dimensional form results in a fitting method with few hooks and a roof plate having a reduced strength. Therefore, in use, there is a problem that the support interval is narrow in terms of strength, the number of base materials is increased, and the base cost is increased.
In addition, the connection with a small shape has a problem in molding accuracy, and the connection at the top is strong, and the position far from the valley where the negative pressure is applied is disadvantageous. Furthermore, the top portion is a single plate crest strength, the angle of the falling piece is upright, and it is not known whether buckling or destruction falls to the left or right. Furthermore, there is a problem with the transfer of the base material because the valley plate is in contact with the width of the base material. In addition, when screws are fixed to the flange, there is a problem of water leakage in the screw holes. Basically, if it is a dredge function, it is necessary to devise a method that does not drill holes. Furthermore, the utilization of the shape of the folded portion has the problem of less versatile added value.

  Note that claims 3, 4, and 5 of Patent Document 2 are out of scope.

  Therefore, in the construction of the fitting type building board, the present invention has a number of problems described in the background art when using roofing materials and wall materials, complicated connection shapes, large force using a tightening machine, locking The shape that scratches the painted surface by tightening or tightening, the connection part on one side against negative pressure, the position of the connection part disadvantageous to negative pressure, the bending of the connection part is difficult and accuracy is difficult, and the strength varies when loaded Overcome problems such as certain support parts, shapes that are difficult to prevent water leakage and attachment of attachments, and the width of the base material transferred to the surface during construction and snowfall, making it easy, reliable, and attached functions In addition, the purpose is to propose a fitting-type building board and its structure that come out at a low price.

  As a result of diligent research to overcome the above-mentioned problems of the prior art and realize the above-mentioned object, the present invention according to the following summary configuration was developed. That is, the present invention forms the valley 2 of the main plate and the ribs 32 and 36 projecting downward at both ends of the valley, and then the step 29 and the step 29 to the oblique side 3 rising obliquely upward on the side that is overlapped at the time of connection. A fitted part 4 is provided, a substantially horizontal peak part 5 and a groove 51 are formed, and the fitted part 6 is provided on a hypotenuse that falls diagonally downward from the outer end of the peak part, and further inclined downward. The inclined support portion 7 and the support point 16 for supporting the building board are provided, and the mountain-shaped fixing portion 8 to be attached and the bent piece 13 for hanging the member are formed at the outer end portion thereof. On the other hand, the side to be overlapped at the time of connection is provided with a step 39 and a fitting portion 10 on the hypotenuse 9 that rises obliquely upward from the rib at the end of the trough, forming a substantially horizontal crest 11 connected thereto, Proposed is a fitting-type building board characterized by forming a fitting portion 12 on the side that overlaps with a hypotenuse that falls diagonally downward from an outer end.

  First, the rivets that are connected to each other using roofing machines are made into large open shapes that are easy to mold, and straightening deformation using the clamping machines is stopped. And the mountain width is wide, and the shape is improved to be easy to mold. In addition, since there is no correction deformation of wrinkles, there are no paint scratches, and the problems of tightening and molding difficulty are overcome.

  Next, avoiding the top of the high position, which is disadvantageous in terms of strength with respect to the strength, stop the hook connection on one side and fitting with less locking, and both sides of the hypotenuse part at the low position Into a large hanging shape. In addition, the pile on the side where the connection part is overlapped and the mating part are overlapped and connected in almost the same shape, so that the strength of the two plates is achieved, and a strong fitting type building board with both-side fitting is achieved. Realize.

  In addition, in order to prevent the strength from being varied, the support portion is inclined to be inclined in a certain direction. This overcomes the problem.

Furthermore, for the transfer of the base material, at least two support points 32 (indicated by a triangle in FIG. 1) and 36 (indicated by a triangle in FIG. 1) projecting on both sides of the valley are provided in the valley of the main plate. In addition, the supporting plate 16 (shown in FIG. 1A) of the inclined support portion is formed in one place, each of which is in a linear shape, touches the base material, and is supported by at least three points or more. Propose. This can overcome the problem. In addition, the rib 34 corresponding to loading can also be added to a trough part. Further, it is proposed that the bent portions of the second step portions 31 and 37 are formed at the bending points of the oblique sides rising to the outside of the support point ribs on both sides of the valley portion, and the fulcrum interval can be widened by the size of this width.

  Next, with respect to the waterproofness of the ridge and its utilization, a groove is provided in the top of the upper mountain where water leaks to provide a secondary waterproof function to avoid water leakage from the connecting portion. Even if water leaks, the next mountain-shaped fixing part 8 is tertiary waterproofed. Furthermore, the mountain shape is such that screw holes do not come in the path of water leakage, and the mountain shape has an effect of preventing screw loosening. The problem can be overcome without problems. Also, a bent rising piece is provided to propose a bent piece for hanging the member.

In response to the problem described in Patent Document 2, first, the flanges connected to each other of the roof material are formed into a large open shape that is easy to mold. The width of the mountain is widened to overcome problems that are difficult to mold. In addition, because the mountain width has been expanded, steel elasticity can be used, and a connection using a springback on the hypotenuse of the mountain has become possible. Next, with respect to strength, the connection part avoids the top part where the strength is disadvantageous, and furthermore, it can be connected on both sides of the hypotenuse part at a low position by stopping hook connection on one side and fitting with little locking. became. In addition, the peak portion overlaps the two plates so that the strength can be increased. Further, in order to prevent the strength from being varied, the support portion is inclined to be inclined in a certain direction. Overcoming these challenges.
Moreover, it proposes sticking a heat insulating material to the back surface as needed for the fitting type building board of this invention.

  Next, according to the present invention, the fitting-type building board is fixed to the roof base material with screws at a predetermined interval, and is attached while the connection fitting portion is connected. Place the fitting part on the side where the plate is connected and piled up, and the angle fixing part connected to the inclined support piece on the base material, fix the screw to the base material, and connect the fitting part on the overlapping side to be connected from above We propose a structure of a fitting-type building board characterized by being stacked on a fitting portion, stepped on with a foot, connected, and crawled sequentially. We also propose a mounting structure that supports the load at three points.

  Furthermore, this invention proposes the structure of the fitting type building board characterized by being able to suspend a member to the bending piece which rises from the fixing | fixed part of the said fitting type building board.

  In order to overcome the problem, it is possible to easily attach the ceiling material by arranging the hanging metal fittings for suspension, and conventionally, the roof material was suspended by drilling a hole in the peak of the roof material. The method is a structure that can be mounted without drilling holes.

The present invention adopting the above-described configuration has a shape of the fitting type building board that is substantially horizontal, which is easy to mold and has a margin for molding accuracy, from the conventional locking shape closed with a small bowl shape. A wide mountain shape. As a result, the small flange corresponding to the locking part and the connection part of the flange of Patent Documents 1 and 2 has a large fitting shape with an open substantially L shape. As a result, on the stacking side, the elasticity of the thin steel plate can be used to increase the effect of the spring back of the wide mountain, so that it is not necessary to deform the mated part on the stacking side, Only by deformation of the fitting portion, the engagement of the fitting could be greatly and easily connected. With this simple connection, the connection speed has been greatly improved by about 20 to 30% over the conventional labor for tightening.
In addition, about the fitting property to a fitting part and a to-be-fitted part conventionally, there is a possibility that the to-be-fitted part side may be in the state of pushing the arm into the goodwill (FIG. 6) against the pressing force from the top. In the present invention, the slanted side, the valley plate, and the supporting portion that continue downward from the fitted portion can be sufficiently reacted with respect to the pressing force, thereby enabling fitting without any problem.
However, the connecting portion to be connected is easy to mold, the molding accuracy is moderated, a clamping machine is not required, and the step of the large engaging portion on both sides can be fitted by manual pressing. The tightening correction of the buttock with a tightening machine is no longer necessary, and the problem of scratches on the painted surface has been solved. For this reason, a stable and accurate product can be constructed with a safe, secure and reliable fitting-type building board, and the construction efficiency has been greatly improved. In addition, it is waterproof and has a wide mountain width, a large step in the fitting part is formed on the slope on the overlapping side, and there is a secondary waterproof groove in the center of the mountain, which greatly improves the waterproof property.

  Next, in terms of strength, first, since the conventional one-side hook is less lifted resistance to the negative pressure from the valley side on the side without the hook, the present invention, as a response to the lift of the valley on one side, A fitting part is formed in the upper part of the support part on the side to be overlapped, and the fitting part is overlapped with the overlapping part. This enables the connection fitting on the overlapping side at a position lower than the mountain and close to the valley. On the other hand, in the fitting on the overlapping side, a fitted portion is provided on the upper side of the oblique side rising from the valley, and the fitting portion is connected and fitted to the fitted portion by the fitting portion stacked from above. This allows connection fitting on both sides of the valley. This makes it possible to respond with less bending moment than the bending moment applied to the top, and to provide a safe fitting mating type construction board with both sides mated against the fear of strength reduction, lifting noise, scattering, etc. due to conventional one-side hooking. Can be provided.

  In addition, the ridges and the fittings fit firmly in almost the same shape and overlap with each other, so that a large strength can be obtained compared to the conventional top made up of a single plate. It was.

  In addition, since the hanging piece or the falling piece that supports the peak portion or the oblique side portion is upright, it does not understand whether it falls down to the left or right, so that the variation in strength increases. In order to avoid this, the upright piece was replaced with an inclined support piece. As a result, it always inclines in a certain direction during loading, leading to buckling and breakage, and a stable strength with little variation could be obtained.

Furthermore, the surface where the valley plate portion is in contact with the base material at regular intervals bites into the base material at a certain interval due to stepping during construction or loading during snowfall, and the width of the base material is transferred, making it unsightly. As a means for solving this problem, downward ribs 32 and 36 are provided at both ends of the valley plate so that a load is applied to the rib on the surface in contact with the substrate so that the transfer of the substrate material to the flat valley plate is difficult. As a result, it was possible to form a valley plate that has a design that does not have any problem in design because the protrusion width of the rib can minimize the biting of the base width, and even if transferred to the rib, it is difficult to see on the bottom surface of the rib. In addition, a rib demonstrates an effect also with a round shape, and can also increase as needed.
Further, the present invention basically provides at least three support points for the load capacity. The support portion is a first support point, a second support point at two ribs on both ends of the valley portion, and a third support point, and each support portion is linear. Further, support points can be added to the valleys as needed. Next, the support point of this valley part can be changed to the bending point of the hypotenuse rising from the valley part by the step and the hypotenuse angle rising, and the position and distance of the support point can be changed. As a result, the load on the loaded snow, solar battery panels and other workpieces can be handled in a balanced and efficient manner.

By forming the fixing part into a mountain shape and providing the fixing part 15 in the shape of the fixing part 8 connected to the support part, slight water leakage or condensed water that has intruded should contact the screw hole at a high position from the groove. Will not do. Since water is drained from the groove of the support portion 16 and the mountain-shaped fixed piece 15 to the eaves, water does not leak from the screw hole. Moreover, in the case of the amount of water leakage exceeding the mountain-shaped fixed piece, the water is drained by a groove between the bent pieces 13 at the end, and a quaternary waterproof is also formed, thereby ensuring the function of the bag.

  Next, since the member is attached to the fixed part, the flat part is angled to increase the strength so that the load resistance is effective. By forming a bent piece with a portion, a member or a ceiling material can be easily attached to the fitting-type building board, which contributes to a reduction in the amount of conventional base material used. The present invention is a structure in which a bending piece for suspension is provided on the fixed portion of the fitting type building board, and a value added to attach a ceiling material, a fence, or the like.

As described above, the fitting type building board of the present invention is connected to one side against the complex shape, the use of a tightening machine, scratches on the painted surface, negative pressure when using roofing materials and wall materials. For connecting parts, disadvantageous positions for negative pressure, small shape of connection part, molding accuracy is difficult, variation in strength when loading, prevention of water leakage and attachment of attachments, streaks of base materials during construction and snowfall, etc. Overcoming issues such as effective fulcrum, etc., it was possible to propose a structure of a mating type building board that is easy, safe and secure, and has an attached function, which is effective in reducing costs.

The preferred embodiments of the present invention will be described below.

  First, in FIG. 1, the trough portion 2 is a main plate, ribs 32 and 36 projecting downward at both ends of the trough portion are formed, and the slant side portion 3 rising from the trough portion 32 obliquely upward on the side that is overlapped at the time of connection. A step 29 is provided, and the oblique sides 28 and 30 are adjacent to each other at the front and rear, and a fitting piece 26 that forms the fitted portion 4, a fitting bent portion 25, and a fitting oblique side 24 are provided at the upper portion of the oblique side. A groove 51 is formed in the ridge 5 and the ridge, and a fitting oblique side 22, a fitting bending point 21, and a fitting piece are formed on the oblique side falling obliquely downward from the outer end of the ridge. 20, and further, a support piece 17 and a support point 16 are formed on the inclined support portion 7 that supports the building board while being inclined downward from the fitting point 19, and the angle fixing portion is attached to the outside from the support point. 8, a mountain-shaped fixing piece 15 is formed in the mountain-shaped fixing portion, and a suspension member at the outer end portion thereof Forming a bending piece 13 for hanging member rising from lifting point 14. On the other hand, on the side to be overlapped at the time of connection, a step 39 is provided in the hypotenuse 9 that rises obliquely upward outward from the rib 36 at the left end of the valley, the hypotenuses 38 and 40 are adjacent to each other, and the fitting portion 10 is located above the hypotenuse. A fitting piece 42, a fitting bent portion 43, and a fitting oblique side 44 are formed to form a substantially horizontal mountain portion 11 connected to the fitting piece 42, and overlapped with the oblique side portion that falls obliquely downward from the outer end portion of the mountain portion. This is a fitting-type building board 1 having a fitting oblique side 46, a fitting bent portion 47, and a fitting piece 48 that form the fitting portion 12, and a laminated piece 50 that extends downward from a fitting point 49. .

There is another shape that widens the range of use of the present invention, and as shown in FIG. 2, first, a downward rib 34 is formed at the center of the face of the valley plate 2. This is provided when a large load is applied to the valley, and can be added as necessary. Further, the valley plate can be provided with second steps 31 and 37 that change the distance by moving the support points at the bending points that rise from the outside of the ribs at both ends of 33 and 35 to the slope. This is intended to allow the support point distance (shown in FIG. 1A) to be freely changed in an advantageous manner with respect to the load. In addition, the angles of the oblique sides 3 and 9 can be freely changed. Thereby, arrangement | positioning with sufficient balance with respect to a load load can be performed. Further, a capillary prevention groove 51 is formed at the peak of the peak 5. This is a secondary waterproofing provided in order to prevent water leakage from the top of the mountain to the indoor support part 7 in the event that rainwater enters the fitting part. As a result, the fixed portion basically does not leak.

Further, a method and structure for mounting the fitting type building board of the present invention will be described. FIG. 3 shows a state of fitting before connection and a state of connection fitting and attachment, and shows an implementation state and structure in which the fixing portion 8 is fixed to the base material 101 with screws 102. In connection fitting at this time, first, the base material to be fixed is arranged at regular intervals as shown in FIG. The mountain-shaped fixing piece 15 of the fixing portion 8 is fixed to the base material 101 with fixing screws 102, and the upper mating portion 6 connected from the support portion 7 is fixed, and the mountain portion 5, the valley portion 2, and the mountain on the overlapping side are connected to it. The fitting part 10 and 12 is arrange | positioned simultaneously with the part 11. FIG. The next fitting type building board 1 adjacent to this state is connected, but the fitting parts 10 and 12 are superimposed on the fitted parts 4 and 6 as shown in FIG. Next, as shown in FIG. 7, they are stepped on with their feet toward the mated portions 4 and 6 from above. As a result, the pile 5 on the side to be overlapped and the mated portions 19, 21, 22, and 24, 25, 26 are overlapped with the mountain 11 on the overlap side and the fitting portions 41, 42, 43, 44, 46, 47, 48. , 49, 50 are fitted in close contact. In the shape having a wide mountain width, the pile on the overlapping side and the fitting portion are greatly opened by the spring back, and the fitting portion is easily fitted. This is repeated in sequence. FIG. 4 shows an example of the rolled-up state. As a result, the construction efficiency of the fitting to be connected is 20-30% more efficient than the conventional tightening work.
In addition, although the example of the fitting state concerned about conventionally is shown in FIG. 6, when there is no support part in the one side of a to-be-fitted part, there is no reaction force with respect to an upper press like FIG. The arm is pushed. In the case of the present invention, since there is an effective reaction force support 7 as shown in FIG. 7, such a problem does not occur.

  Moreover, although the Example which attached the board | plate 1 for fitting type construction of this invention to the roof is shown in FIG. 4 and the wall is not illustrated, if there exists the same base material 101, it can affix similarly to a roof. .

Next, an example in which a hanging metal fitting is used for the fitting type building board of the present invention, the ceiling member is suspended, and the ceiling board is stretched will be described with reference to FIG. This is provided with a bent piece 13 for suspension at the end of the fixed portion, but the bent pieces are engaged with each other when the hanging fitting 103 is hooked, and are shaped so as not to come off. Thereby, a safe hanging structure can be achieved. Further, in order to cope with the load of the hanging portion, the center of the mountain-shaped fixing portion is formed in a mountain shape so that the strength is increased, and the structure is devised to cope with the load even a little.

  Moreover, as an example of extending the ceiling plate, FIG. 9 shows an example in which the ceiling plate is directly stretched from the back surface to the mountain-shaped piece 15 of the mountain-shaped fixing portion 8 from the back surface of the fitting type building board of the present invention.

  Furthermore, although the attachment state of the conventional fence is shown in FIG. 10 with respect to the attachment of the fence, a hole was drilled on the roof plate on the spot and the fence was attached with a suspension bolt. For this reason, the trouble of drilling the roof plate, corrosion, and the like have been problems. For the improvement, FIG. 11 shows a state in which the eaves cage 106 is attached using the hanging metal fitting 103 using the mountain-shaped fixing piece and the bent portion of the fitting type building board 1 of the present invention. FIG. 12 shows a state viewed from the front. Thus, if a hanging metal fitting is used, it can be easily attached. It is an installation structure that requires less labor and does not damage the roofing material.

  As described above, the fitting-type building board of the present invention has an advantageous connection position in terms of shape, formability, forming accuracy, shape that can be connected manually without using a tightening machine, and scratched coating surface.
