Description

Stranded hidden steel plate

The invention relates to a twisted hidden steel plate, in particular to a plurality of non-parallel protrusions provided on a plate surface portion of a steel plate to strengthen the wind pressure resistance of the steel plate and improve the wind pressure resistance of the steel plate on the roof of a metal building. Ensure the structural safety and practicability of the building.

The conventional twisted concealed steel plate is shown in FIG. 1 and FIG. 2. The steel plate 1 includes a plate surface portion 10, a first overlap portion 11 and a second overlap portion 12. The plate surface portion 10 is planar and has not been processed into any reinforcing structure. Or as shown in the second type of the learner of FIGS. 3 and 4, the steel plate 2 includes a plate surface portion 20, a first overlap portion 21 and a second overlap portion 22, and the plate surface portion 20 of the second type of learner is formed with a straight direction. The peak portion 20b is parallel to the first overlapping portion and the second overlapping portion. Or as shown in the third example of FIG. 5, the steel plate 5 includes a plate surface portion 50, a first overlap portion 51 and a second overlap portion 52, and the plate surface portion 50 of the third person is formed with a straight peak portion. 50b, and is parallel to the first overlapping portion and the second overlapping portion. The various conventional technologies mentioned above, even during the installation and construction, the first overlapped portion and the second overlapped portion are combined with the fixing base 13 by a twisting machine to form a twisted end a. The wind pressure from the inside or outside of the building is pushed outward or upward at non-fixed intervals from the inside or outside of the steel plate surface. The inside of the steel plate surface will be subjected to wind pressure once, twice, three times, etc. Each attack will cause the board surface to distort and deform at the same time, and simultaneously pull the twisted end, gradually destroying the joint state of the twisted end. When the deformation of the board surface gradually increases, the strength of the twisted end will increase at the same time, and eventually The largest destructive force on the twisted end causes the first overlapped portion and the second overlapped portion of the twisted end to be forced to separate, and the steel roof of the building will be completely opened and destroyed, causing damage to the building.

As shown in the fourth person of FIG. 6, the steel plate 6 includes a plate portion 60, a first overlap portion 61, a second overlap portion 62, and a central overlap portion 63. It has a straight peak portion 60b, and is parallel to the first overlap portion 61, the second overlap portion 62, and the central overlap portion 63. As mentioned above, even during the installation and construction, the first overlapped portion and the second overlapped portion are combined with the fixing base 13 by a twisting machine to form a twisted end a. However, when the inner side or the outer side of the plate portion of the steel plate is strongly The wind pressure is pushed outward or upward from the inside or outside of the building to the inside or outside of the steel plate surface at non-fixed intervals. The inside of the steel plate surface will be subjected to wind pressure once, twice, three times, etc. Strong strike, each strike will cause the board face to twist and deform upwards, and simultaneously pull the twisted ends, gradually destroying the joint state of the twisted ends. When the board face deformation gradually increases, the strength of the twisted ends will increase at the same time. The twisted end produces the largest destructive force, causing the first overlapped portion and the second overlapped portion of the twisted end to be forced to separate, and the steel roof of the building will be completely opened and destroyed, causing damage to the building.

Or, as shown in the invention patent No. I605178 ｢Concealed integrally formed fire-resistant and flame-resistant composite steel sheet", the board surface, the first joint and the second joint are formed together. If no fire-resistant and flame-resistant layer or foam layer is provided, it will also occur. As the aforementioned person knows, the inside or outside of the steel plate face will be subjected to countless strong blows by strong wind pressure, which will cause the plate face to distort and deform at the same time, and simultaneously pull the twisted ends, gradually destroying the combined state of the twisted ends.

Or, for example, the new patent No. M348802 ｢Hidden twisted integrally formed steel plate," although the surface of the plate is provided with a straight grain, but it is parallel to the first overlap portion and the second overlap portion. The foamed layer will also occur as the aforementioned person knows. The inside or outside of the steel plate face will be subjected to countless strong blows from high wind pressure, which will cause the plate face to distort and deform at the same time, and at the same time pull the twisted ends, gradually destroying the twisted ends. Problems with status.

Secondly, the construction of the twisted hidden steel plate is known. In order to make the construction fast, no soft objects or glues will be injected into the twisted end in advance, so that the twisted end has the function of filling and waterproofing. And when the adjacent steel plates are formed by the first and second overlapping portions twisted and twisted with each other, a fixed seat will be provided every distance of three to three meters, so that the foregoing adjacent steel plates are twisted. End, within a length range of each to three meters, that is, it can be supported without a fixed seat. In this way, when the twisting construction is performed by a twisting machine, since the twisting clamping force of the twisting machine is set according to the shape and structure of the twisted end of the adjacent steel plate, there is a twisted end provided with a fixed seat. (Approximately 15 cm in length) has the strongest clamping and bonding state, and the remaining one to three meters of the twisted end without a clamping seat is only within the length range where the first and second laps are combined with each other. It will generate at least one or more plate thickness differences between the twisted end with the fixed mount and the twisted end without the fixed mount, which will cause the twisted end without the fixed mount to be twisted completely. The twisted ends within the length range will create gaps, which are easy for airflow to pass or water infiltration, resulting in strong wind damage and water leakage problems.

For this reason, the inventor of this case based on his experience in the design and manufacturing of metal building materials and equipment, and specifically studied the problems of previously known technologies, and invented this case.

The object of the present invention is to provide an innovation of a twisted hidden steel plate that can improve the wind pressure resistance structure of a metal building to strengthen the structural strength of the metal building.

In order to achieve the foregoing object, the twisted hidden steel plate of the present invention includes at least: a steel plate, which is composed of a plate surface portion, a first overlapping portion and a second overlapping portion, and the plate surface portion is provided with a plurality of strip-shaped protrusions, and the protrusions The setting direction of the rising portion is non-parallel to the bending direction of the first overlapping portion and the second overlapping portion. The two sides of the protruding portion are respectively between the first overlapping portion and the second overlapping portion. First and second spacing planes are formed to improve the wind resistance effect of metal buildings. The first overlapping part is first connected to the fixing seat, and then the second overlapping part of the adjacent steel plate is connected to the foregoing. The first overlapping part is overlapped with each other, and then the three are twisted to form a twisted end by a twisting machine, so that the adjacent two steel plates can be combined into one body, thereby improving the beauty and practicality of the metal building.

In the twisted concealed steel sheet of the present invention, the aforementioned raised portions may have raised structures of various shapes such as a rectangle, a triangle, a diamond, a polyline, or an oval.

According to the present invention, a sealing tape can be filled inside the second overlapped portion of the steel plate when the factory manufactures the molding or when it is processed at the construction site, and the sealing tape is a heat-resistant, cold-resistant, high-compression, arbitrarily shaped and The non-curing glue material is used as a medium for gluing, caulking and raising the twisted ends of adjacent steel plates.

The twisted hidden steel plate of the present invention can also be applied to the technical features of buckled hidden steel plates.

In order to allow the expensive examiner to fully understand the twisted hidden steel plate of the present invention, it is explained with the following drawings:

As shown in FIGS. 7 and 8, the present invention includes at least: a steel plate 3, which is composed of a plate surface portion 30, a first overlapping portion 31, and a second overlapping portion 32. The plate surface portion 30 is provided with a plurality of strip-shaped protrusions 30a. The direction of the protrusions 30a is not parallel to the bending direction of the first overlapping portion 31 and the second overlapping portion 32 (which must be vertical) (It can be installed or installed obliquely.) The aforementioned convex portion 30a is composed of a ring-shaped inclined surface 300 and a block surface 301. The shape of the convex portion 30a is rectangular (as shown in Fig. 10A), broken line (as shown in Fig. 10B), and ellipse. Shapes (as shown in Figure 10C) are all indispensable. In this way, a corresponding recessed area 302 is formed at the bottom of the aforementioned raised portion 30a, so as to produce the effect of strengthening the surface of the board by the plurality of raised portions 30a.

As shown in FIGS. 7-9, the direction of the protrusion 30a should be perpendicular to the bending direction of the first overlapped portion 31 and the second overlapped portion 32. In this way, the A first gap plane 330 is formed between one side and the first overlapped portion 31, and a second gap plane 331 is formed between the other side of the raised portion 30a and the second overlapped portion 32. The aforementioned first interval plane 330 and the second interval plane 331 form a drainage and water-conducting plane of the building roof. As shown in Figs. 15 and 16, the aforementioned first overlapped portion and the second overlapped portion may be of any shape, and it is indispensable.

As shown in Figs. 11 and 12, the steel sheet of the present invention can be filled with a non-curing sealant 34 inside the second overlap portion 32 of the steel sheet when the steel sheet is manufactured in a factory or processed at a construction site. The rubber strip (such as butyl rubber, etc.) can be a long flat shape (as shown in Figure 11) or a long cylindrical shape (as shown in Figure 12) or other shapes. The aforementioned sealing strip 34 is a heat-resistant, cold-resistant, high-compression plastic material that can be arbitrarily shaped and never solidifies, and can be directly injected and adhered to the inner side of the second overlapping portion during the steel plate forming process.

As shown in Figures 13 and 14, when the adjacent steel plates are combined with the first overlapping portion and the second overlapping portion to form the twisted end 36, it is usually necessary to set a fixing seat 35 between one and three meters depending on the thickness of the steel plate. In this way, the first overlapped portion 31 of the steel plate 3a and the second overlapped portion 32 of the steel plate 3b are twisted with each other to form a twisted end 36 by a twisting machine, and the distance between the twisted end 36 and each of the three meters will be clamped. If one fixed base 35 is fixed, there will be no fixed base within the range of one to three meters, so that the thickness difference between the twisted end with the fixed base 35 and the twisted end without the fixed base is at least There is a difference between the thickness of the plate thickness of a fixed seat or more.

However, when using a twisting machine to perform the clamping twisting construction, the twisting force of the twisting machine has been set according to the shape and structure of the twisted end, and it does not actively distinguish the twisted end with or without a fixed seat. Therefore, the difference between the thickness of the twisted end with the clamped mount and the twisted end without the clamped mount is different from the strength of the twisted mechanical clamping, and the combined state of the twisted end after clamping will be different. A little different. In order to solve the foregoing problems, the present invention can use a sealing strip 34 that is not easily cured, can be arbitrarily shaped, and can withstand high pressure as a medium for gluing, caulking, and cushioning the twisted ends 36. When there are twisted ends with clamped mounts and twisted ends without clamped mounts, the clamping pressure on the sealing strip 34 will be different, and the two will also affect the shape of the sealing strip. It will be different. In this way, the aforementioned sealing strip can be filled in time and heightened the shape and height of the twisted end without the clamp, so that the twisted end with the clamp and the twisted end without the clamp can be twisted. The machine can apply the same clamping force channel, and make the clamping force channel of the twisted end consistent, eliminating the problem of gap leakage that may occur at the twisted end without the clamping seat, and ensure that the twisted end 36 does not leak. No gaps, will not be forced to pass through air or water vapor, which can improve the safety structure and wind pressure coefficient of metal buildings.

As shown in Figs. 13 and 14, when the installation and construction are performed according to the present invention, first the first overlapping portion 31 of the steel plate 3a is slightly combined with the fixing base 35, and then the second overlapping portion 32 of the adjacent steel plate 3b and the aforementioned steel plate The first overlapping portion 31 of 3a is combined with the fixing base 35, and then the first overlapping portion 31 of the steel plate 3a, the fixing base 35, and the second overlapping portion 32 of the steel plate 3b are twisted with each other by a twisting machine. At this time, the inside of the second overlapping portion 32 of the steel plate 3b can be covered with a pre-filled sealant 34 to cover the outside of the first overlapping portion 31 and the fixing seat 35, so that the first overlapping portion 31 of the steel plate 3a can be covered. The fixed base 35 and the second overlapping portion 32 of the steel plate 3b are twisted to each other. The twisted ends 36 produced after the twisting are fully glued and caulked, which can not only improve the anti-wind pressure effect of metal buildings, but also prevent airflow. Enter the inside of the twisted end, or water and gas enter the room through the twisted end to improve the safety and practicality of the metal building. And as shown in Figure 13, when a large negative wind pressure hits the inside of the plate surface of the steel plate, the aforementioned convex portion, the first overlapping portion and the second overlapping portion may be vertically arranged to strengthen the wind pressure resistance of the steel plate. , Will not deform, and can prevent the twisted ends 36 of adjacent two steel plates from being pulled and deformed, and improve the safety of the building.

To sum up, the twisted hidden steel plate of the present invention can strengthen the structure of the steel plate by the convex portion provided on the plate surface portion of the steel plate. When installed on the roof, it can withstand large negative wind pressure, which is not easy. Destroyed by strong wind, and because the second overlapping portion is pre-filled with a sealing strip, it can be used as a bonding and caulking medium for the first overlapping portion, the fixing seat and the second overlapping portion of the adjacent steel plate. The permanent non-curing function can automatically match the change of the twisted end at any time to automatically generate the glue seal effect, so that the bonding between adjacent steel plates is more stable, and the wind resistance and structural strength of the metal building are increased, and the metal building is increased. Safety and practicability, the present invention does have practical value, which is a novel and progressive composition of the present case.

The foregoing embodiments or drawings do not limit the form or use of the present invention, and any appropriate changes or modifications of persons with ordinary knowledge in the technical field should be deemed to not depart from the patent scope of the present invention.
