Description

Technical Field

[0001] The present invention relates to the technical field of building roof enclosures, and more specifically, to a weathering steel plate building roof enclosure system. Background Art

[0002] With the progress of society and the development of the construction industry, metal plates have become common as the outer surface of buildings. In particular, aluminum plates are the most widely used, but weathering steel plates are still rare as building roof layers in China. In fact, as early as the 1990s, many architects began to directly apply untreated weathering steel plates to exterior walls, ceilings, and even roofs in order to pursue the natural rusting effect of the steel plates. In the atmospheric environment, the surface layer of the steel plate gradually oxidizes and changes color, and the flow of rainwater leaves rust marks on the surface of the steel plate and even on the wall connected to the steel plate, forming a special effect.

[0003] However, the atmospheric corrosion resistance of general structural steel (ordinary carbon steel) is poor, resulting in a short service life when it is exposed to the atmospheric environment for a long time.

[0004] The atmospheric corrosion resistance of weathering steel is 3 to 4 times that of general structural steel. Even under the condition of bare use, its corrosion resistance life can reach more than 30 years. Weathering steel is simple and convenient to use. It can be painted or used without a protective layer exposed, which simplifies the production process. Since existing processes such as pickling and hot-dip galvanizing are eliminated, the production and manufacturing costs are reduced. At the same time, not using paint can prevent the volatilization of VOC (volatile organic compounds), which is more conducive to recycling and is of great benefit to environmental protection. When a protective paint is applied to the surface of weathering steel, the life of the paint surface can reach twice that of ordinary carbon steel. Therefore, it is necessary to propose a weathering steel plate building roof enclosure system to at least partially solve the problems existing in the prior art. Summary of the Invention

[0042] The following further elaborates on the present invention in conjunction with the accompanying drawings and embodiments, so that those skilled in the art can implement it with reference to the text of the specification.

[0043] It should be understood that terms such as "having", "comprising", and "including" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0044] Weathering steel, that is, atmospheric corrosion-resistant steel, is a series of low-alloy steels between ordinary steel and stainless steel. Weathering steel is made by adding a small amount of corrosion-resistant elements such as copper and nickel to plain carbon steel, and has the characteristics of high-strength, ductility, formability, welding and cutting, abrasion resistance, high temperature resistance, fatigue resistance, etc. of high-quality steel; the weather resistance is 2 to 8 times that of plain carbon steel, and the painting property is 1.5 to 10 times that of plain carbon steel. At the same time, it has rust resistance, enabling components to resist corrosion and extend their service life, reducing thickness and consumption, saving labor and energy, etc.

[0045] Currently, weathering steel is mainly used in steel structures such as railways, vehicles, bridges, tower racks, photovoltaic, and high-speed projects that are exposed to the atmosphere for a long time. It is used to manufacture structural parts such as containers, railway vehicles, oil well frames, seaport buildings, oil production platforms, and containers containing hydrogen sulfide corrosion media in chemical and petroleum equipment.

[0046] The present invention applies weathering steel plates to building roof enclosures, thereby reducing the production cost of roof enclosures and extending the service life of roof enclosures.

[0047] As Figures 1-14 shown, the present invention provides a weathering steel plate building roof enclosure system, including: a roof purlin 1, a profiled sheet 2, a protective layer 3, a weathering steel plate keel 4, and a weathering steel plate 5 that are connected in sequence. The roof purlin 1 is connected to the main structure 15 through purlin brackets, and the roof purlins 1 are arranged in parallel at the designed spacing.

[0048] Working principle and beneficial effects of the above technical solution: The entire weathering steel sheet roof enclosure system needs to be constructed layer by layer from bottom to top for the roof purlins 1, profiled sheet 2, protective layer 3, weathering steel sheet keel 4, and weathering steel sheet 5. The roof purlins 1 are generally made of galvanized cold-formed C-shaped or Z-shaped steel, determined according to design requirements. During construction, they are installed in place with the main structure 15 through purlin brackets along with the structure. The installation of the roof purlins 1 needs to be accurate in position and evenly arranged, and arranged according to the designed spacing to ensure the stability of the roof enclosure system;

[0049] The main structure 15 is the structure of the house, and self-tapping screws can be used to connect and fix between each component;

[0050] The weathering steel sheet 5 is made of weathering steel. As the outermost layer of the roof enclosure system, it can meet the architect's requirement for the "natural rust change effect of the steel sheet" on the roof appearance. At the same time, it improves the waterproof performance and service life of the roof enclosure structure. The use of weathering steel sheet roof simplifies the manufacturing process, eliminates existing processes such as pickling and hot-dip galvanizing, and reduces the production and manufacturing costs; and when a protective paint needs to be coated on the surface of the weathering steel sheet 5, the service life of the paint surface can also reach twice that of ordinary carbon steel.

[0051] In one embodiment, the protective layer 3 includes: a vapor barrier layer 310, a thermal insulation layer 320, and a waterproof layer 330 connected in sequence. The vapor barrier layer 310 is connected to the profiled sheet 2;

[0052] The thermal insulation layer 320 includes at least two layers of rock wool boards 321.

[0053] Working principle and beneficial effects of the above technical solution: The vapor barrier layer 310 uses a non-woven fabric vapor barrier layer to prevent indoor water vapor from penetrating into the thermal insulation layer 320. The thermal insulation layer 320 uses two layers of 70-mm-thick rock wool boards 321 arranged in a staggered and layered manner to play a thermal insulation role. The vapor barrier layer 310 is laid on the profiled sheet 2, and the two layers of rock wool boards 321 are laid on the vapor barrier layer 310. Then, the rock wool boards 321 are fixed to the profiled sheet 2 with self-tapping screws. The waterproof layer 330 uses TPO membrane for waterproofing to achieve the purpose of effectively waterproofing the main body of the house.

[0054] In one embodiment, it further includes a support member 6. One end of the support member 6 is connected to the profiled sheet 2 and the roof purlin 1, and the other end of the support member 6 passes through the protective layer 3 and is connected to the weathering steel sheet keel 4;

[0055] The support member 6 includes: a U-shaped top support 610 connected to the weathering steel sheet keel 4. The bottom end of the U-shaped top support 610 is provided with an eight-shaped connecting member 630 through a support pipe 620. The eight-shaped connecting member 630 corresponds to the trapezoidal corrugated profiled sheet 2, and the eight-shaped connecting member 630, the profiled sheet 2, and the roof purlin 1 are connected by screws;

[0056] The waterproof layer 330 disposed near the support member 6 is turned up to the bottom of the U-shaped top support 610, and the turned-up waterproof layer 330 is connected to the side surface of the support pipe 620.

[0057] The working principle and beneficial effects of the above technical solution: After the roof purlins 1 and profiled sheets 2 are installed in sequence, the support member 6 is installed. During installation, it is necessary to lay out and position in advance on the surface of the installed profiled sheet 2 to ensure the accuracy of the installation position of the support member 6, and at the same time ensure the installation position of the weather-resistant board keel 4. The support member 6 is connected to the profiled sheet 2 and the roof purlin 1 by self-tapping screws, avoiding the problems of on-site welding and punching holes in the profiled sheet 2, and at the same time ensuring the installation quality and installation efficiency;

[0058] The U-shaped top support 610, the support pipe 620 and the inverted V-shaped connecting member 630 are formed by assembling and welding;

[0059] When installing the waterproof layer 330, it is necessary to set up a waterproof wrap at the position of the support member 6, and at the same time seal the gap position with structural glue. The waterproof wrap set at the position of the support member 6 uses an aluminum hoop and self-tapping screws to turn up the waterproof layer 330 at the position of the support member 6, so that the top end of the turned-up waterproof layer 330 reaches the bottom of the U-shaped top support 610, and then the turned-up waterproof layer 330 is locked by the aluminum hoop, and the aluminum hoop, the waterproof layer 330 and the support pipe 620 are fixed by self-tapping screws, and then the gap is sealed with structural glue to ensure the waterproof performance.

[0060] In one embodiment, the profiled sheet 2 and the roof purlin 1 are connected by self-tapping screws. Among them, the self-tapping screws are evenly arranged at intervals along the length direction of the roof purlin 1, and the number and spacing of the self-tapping screws are determined by the following method:

[0061] Step 1: Initially determine the number and spacing of the self-tapping screws according to the length of the roof purlin 1, and establish a relationship between the two:

[0062] L = (x1 - 1)x2

[0063] Wherein, L is the effective installation length of the roof purlin 1, x1 is the number of self-tapping screws, and x2 is the arrangement spacing of the self-tapping screws;

[0064] Step 2: Optimize the initially determined number and spacing of the self-tapping screws by using the following formula:

[0065]

[0066] y1 is a shear force transfer influence parameter related to the number of self-tapping screws, y2 is a shear force transfer influence parameter related to the spacing of self-tapping screws, and ω is an influence judgment parameter;

[0067] Determine whether the initially determined x1 and x2 make the value of y1 equal to or approach the maximum value. If it is equal to or approaches the maximum value, then compare the influence judgment parameter ω with the standard judgment parameter ω0. If ω ≥ ω0, it means that the quantity and spacing of the self-tapping screws meet the force requirements. If ω < ω0, then x1 and x2 need to be optimized to meet the above force requirement conditions.

[0068] The working principle and beneficial effects of the above technical solution: Since the top of the roof enclosure has a certain inclination angle, the connection between the profiled sheet 2 and the roof purlin 1 bears shear force. In order to enable the profiled sheet 2 to better transfer the top load to the roof purlin 1, so that the roof purlin 1 and the profiled sheet 2 and other load-bearing components can share the load;

[0069] L is the effective installation length of the roof purlin 1, which is the distance between the two outermost self-tapping screws;

[0070] When the number of self-tapping screws increases within a certain range, the effect of transferring the load from the profiled sheet 2 to the roof purlin 1 increases accordingly. However, when the number of self-tapping screws exceeds a certain limit value, the load transfer effect will decrease. Therefore, a shear force transfer influence parameter related to the number of self-tapping screws is introduced to determine the number of self-tapping screws. And in the case of a fixed number of self-tapping screws, a shear force transfer influence parameter related to its spacing is introduced. That is, the larger the spacing, the better the load transfer effect between the profiled sheet 2 and the roof purlin 1. So, in order to meet both conditions, an influence judgment parameter is set, and a corresponding standard is set to determine whether the designed number and spacing of self-tapping screws meet the above conditions, thereby making the force effect of the roof enclosure optimal and preventing defects such as structural damage and water leakage due to deformation during long-term use.

[0071] In one embodiment, the weather-resistant plate 5 is formed by splicing a plurality of plate units;

[0072] The plurality of plate units include: a first plate unit 510 and a second plate unit 520 corresponding to the gutter 7 formed on the top enclosure of the roof. A receiving hole is provided on the second plate unit 520.

[0073] The working principle and beneficial effects of the above technical solution: The building roof enclosure system of the present invention adopts internal drainage. The gutter 7 is made of stainless steel and is installed with the main structure 15 through square tube keels. The waterproof layer 330 wraps the gutter 7 and extends to the outside of the parapet wall (the parapet wall is an architectural term, also known as the coping wall, which is a way of connecting the roof and the exterior wall. As a railing on the roof or a measure for the exterior shape treatment of the house, it can prevent people from falling and also play a role in roof waterproofing), ensuring that the inner roof waterproof system is a complete system;

[0074] The second board unit 520 located at the top of the gutter 7 needs to be sized according to the width of the gutter 7, and it is provided with receiving holes formed by punching. The size and density of the receiving holes are determined according to the drainage volume of the roof to ensure that the gutter 7 can collect the rainwater on the roof;

[0075] When the second board unit 520 is installed, it is inlaid in the gap reserved by the first board unit 510 after splicing and installation, and is detachably connected to the first board unit 510 for easy disassembly at any time.

[0076] In one embodiment, the first board unit 510 is connected to the weather-resistant board keel 4 through a splicing member 8, and the second board unit 520 and the adjacent first board unit 510 are detachably connected;

[0077] The splicing member 8 includes: an L-shaped mounting plate 810. The end of the first board unit 510 is bent to form a bent portion 511 corresponding to the L-shaped mounting plate 810. The bent portion 511 and the side plate of the L-shaped mounting plate 810 are connected by bolts 10, and the bottom plate of the L-shaped mounting plate 810 is connected to the weather-resistant board keel 4 by self-tapping screws 11.

[0078] The working principle and beneficial effects of the above technical solution: The first board unit 510 is spliced through the splicing member 8 and is fixed to the weather-resistant board keel 4 through the splicing member 8 at the same time. The second board unit 520 and the first board unit 510 adopt a detachable connection method, which can be embedded in the gap formed between the adjacent first board units 510 after splicing;

[0079] The end of the first board unit 510 is bent to form a bent portion 511. The bent portion 511 and the side plate of the L-shaped mounting plate 810 are connected by bolts 10, and the bottom plate of the L-shaped mounting plate 810 is connected to the weather-resistant board keel 4 by self-tapping screws 11, so that the first board unit 510 is fixed to the weather-resistant board keel 4. The L-shaped mounting plates 810 connected to the adjacent two first board units 510 are arranged staggeredly, which is convenient for connecting to the weather-resistant board keel 4 and ensures the stability of the connection.

[0080] In one embodiment, the concave seam 12 formed at the splicing joint of the adjacent two first board units 510 is filled with a sealant 13;

[0081] After the adjacent two first board units 510 are respectively connected to the weather-resistant board keel 4 through the splicing member 8, a concave seam 12 is formed. The concave seam 12 is filled with a sealant 13. The distance between the surface of the sealant 13 after filling and the surface of the first board unit 510 is 10 mm.

[0082] Working principle and beneficial effects of the above technical solution: The concave seam 12 is formed between the bending parts 511 of two adjacent first plate units 510. Sealant 13 is filled at the concave seam 12 for sealing. The sealant 13 is a weather-resistant sealant, which has certain weather resistance (anti-aging, antioxidant, good toughness), can maintain a certain stability in different environments, and is used for sealing, waterproofing, anti-ultraviolet, etc., and can achieve a secondary waterproof effect on the roof.

[0083] In one embodiment, a drain port 710 communicating with the drain pipe 14 is provided at the bottom of the gutter 7. The drain pipe 14 is arranged between the main structure 15 and the side enclosure of the roof and extends downward to the outside;

[0084] A protection device 9 is provided in the gutter 7. The protection device 9 includes: a first drainage box 910, a trough 920 is provided between two first drainage boxes 910, a second drainage box 930 is provided in the trough 920, a sedimentation mechanism 940 is provided above the second drainage box 930, and a drainage trough 950 is formed between the sides of the two first drainage boxes 910 and the top surface of the sedimentation mechanism 940. The top surface of the first drainage box 910 is inclined toward the side close to the drainage trough 950; an inlet hole group communicating with the drainage trough 950 is provided above the side wall of the first drainage box 910, and a drain hole 911 communicating with the second drainage box 930 is provided below the side wall of the first drainage box 910; the bottoms of the first drainage box 910 and the second drainage box 930 are respectively communicated with the corresponding drain ports 710;

[0085] The sedimentation mechanism 940 includes: a sedimentation plate 941 slidably arranged in the trough 920. Fixed plates 942 connected to the side walls of the trough 920 are provided on both sides below the sedimentation plate 941. Through holes are provided in the fixed plates 942, and connecting rods 943 are slidably arranged in the through holes. The top ends of the connecting rods 943 are connected to the bottom surface of the sedimentation plate 941. A first spring 944 is provided between the sedimentation plate 941 and the fixed plates 942; a water outlet 931 is provided at the bottom of the second drainage box 930. A driving rod 945 is provided at the bottom of the sedimentation plate 941. The driving rod 945 passes through the second drainage box 930 and a blocking block 946 for blocking the water outlet 931 is provided at its bottom end; a space area for the blocking block 946 to move is provided between the bottom surface of the second drainage box 930 and the gutter 7; a groove 921 is provided on the side wall of the trough 920 in its length direction. A limiting plate 947 is rotatably connected in the groove 921. The bottom end of the limiting plate 947 abuts against the top surface of the sedimentation plate 941. A second spring 948 is provided between the limiting plate 947 and the groove 921. A limiting block 949 abutting against the groove 921 is provided on one side of the limiting plate 947;

[0086] The inlet hole group includes: multiple rows of inlet holes 912 with gradually increasing sizes from bottom to top. The bottommost end of the lowermost inlet hole 912 is not higher than the top surface of the sedimentation plate 941;

[0087] The top surface of the sedimentation plate 941 is an inclined surface that slopes towards the side of the water inlet hole 912. There are multiple sedimentation grooves 9411 arranged at intervals on the inclined surface. A protrusion 9412 is formed between two adjacent sedimentation grooves 9411. The sedimentation grooves 9411 and the protrusions 9412 make the inclined surface form a corrugated inclined surface.

[0088] The working principle and beneficial effects of the above technical solution: The drainage pipe 14 is arranged inside the side enclosure of the roof. Its top end is connected to the gutter 7, and its bottom end extends outside the roof enclosure, and is used to drain the water collected in the gutter 7.

[0089] In the prior art, sundries such as sludge are likely to accumulate in the gutter 7, and it is relatively inconvenient to clean. Moreover, if not cleaned in time, it will lead to low drainage efficiency of the roof and there is a risk of blocking the drainage pipe 14. In this way, when the rainfall is large, the drainage system is very likely to break down, resulting in a large amount of water accumulating on the roof and causing water leakage; therefore, based on this problem, this embodiment proposes a solution.

[0090] As Figure 9 shown, the first drainage tank 910 and the tank body 920 are arranged in sequence along the length direction of the gutter 7, and the two are arranged at intervals. The top surface of the first drainage tank 910 is inclined towards the side of the drainage groove 950. If the tank bodies 920 are arranged on both sides of the first drainage tank 910, its top surface can be set to incline towards both sides respectively; the drainage pipe 14 at the bottom of the second drainage tank 930 is a standby pipe.

[0091] During normal drainage, the water on the roof flows into the gutter 7 and flows along the inclined surface of the top surface of the first drainage tank 910 to the sedimentation mechanism 940. The sedimentation plate 941 is used to sediment sundries or sludge and other substances mixed in the water. Most of them are sedimented in the sedimentation grooves 9411, and then the water flows into the first drainage tank 910 through the corrugated inclined surface through the water inlet hole group, and then is drained through the drainage pipe 14 at the bottom of the first drainage tank 910. It should be noted that the total water passing cross-sectional area of the water inlet hole group is larger than the cross-sectional area of the drainage pipe 14; the first drainage tank 910 can cover the drainage pipe 14 arranged at its bottom to prevent foreign objects from entering the drainage pipe 14 and causing blockage. Through the arranged sedimentation mechanism 940, sundries such as sludge mixed in the water can be sedimented, reducing the probability of sludge entering the drainage pipe 14 and further preventing blockage.

[0092] When the displacement is relatively large, the amount of water entering the drainage tank 950 per unit time is relatively large, which will cause the sedimentation plate 941 to move downward to compress the first spring 944. Then, the top surface of the sedimentation plate 941 is located below the lowest point of the drainage hole group. The more water there is in the drainage tank 950, the greater the distance the sedimentation plate 941 moves downward, which can effectively prevent sludge and other sundries from being brought into the drainage hole group by the power during drainage, and prevent the drainage hole group and the drainage pipe 14 from being blocked;

[0093] Moreover, when the displacement is relatively large, after the sedimentation plate 941 moves downward, it will drive the drive rod 945 and the plugging block 946 to move downward. Then, the plugging block 946 will open the water outlet 931 of the second drainage tank 930. At this time, if the water level in the first drainage tank 910 is sufficient to allow water to enter the second drainage tank 930 through the inclined drainage holes 911, the water flow will drain through the standby drainage pipe 14 below the second drainage tank 930, instantly sharing the drainage volume of the drainage pipe 14 below the first drainage tank 910 and improving the drainage efficiency;

[0094] Under normal circumstances, the water outlet 931 at the bottom of the second drainage tank 930 is in a blocked state, that is, the standby drainage pipe 14 will not be blocked by sludge. In this way, even if the drainage pipe 14 below the first drainage tank 910 is blocked and loses its drainage function, the accumulated water flow inside the first drainage tank 910 can still enter the second drainage tank 930 through the drainage holes 911. When the water volume in the second drainage tank 930 reaches a certain height, under the action of water pressure, it will drive the plugging block 946 to move downward to open the water outlet 931, and the water will drain from the standby drainage pipe 14;

[0095] In addition, the sedimentation plate 941 can be conveniently disassembled for sludge cleaning. The top end of the sedimentation plate 941 is connected to the drive rod 945 by screws. The bottom surface of the sedimentation plate 941 is flat and abuts against the connecting rod 943. The installation position of the sedimentation plate 941 is limited by the limiting plate 947. The top end of the limiting plate 947 is rotatably connected in the groove 921. A limiting block 949 is provided on the upper side of the upper end of the limiting plate 947. Thus, when the bottom end of the limiting plate 947 abuts against the top surface of the sedimentation plate 941, the upward elastic force of the first spring 944 will cause the sedimentation plate 941 to push the limiting plate 947 upward. At the same time, the second spring 948 also gives an outward driving force to the limiting plate 947. Under the action of the limiting block 949, the limiting plate 947 will not rotate upward. In this way, the horizontal installation position of the sedimentation plate 941 is limited, and then the plugging block 946 can just limit and block the water outlet 931;

[0096] Therefore, when disassembling the deposition plate 941, the limiting plate 947 is pushed into the groove 921 to compress the second spring 948, then the deposition plate 941 will move upward under the action of the first spring 944, and the deposition plate 941 will be disengaged from the limitation of the limiting plate 947. Then, the screw connecting it to the driving rod 945 is unscrewed, and the deposition plate 941 can be taken out of the tank body 920 for cleaning. After cleaning, only the deposition plate 941 and the driving rod 945 need to be connected by screws, and then the deposition plate 941 is pressed down. During the pressing process, the side surface thereof will exert pressure on the limiting plate 947 to make it retract into the groove 921. When the top surface of the deposition plate 941 is lower than the lowest end of the groove 921, the pressure is removed. Then, under the elastic restoring force of the second spring 948, the bottom end of the limiting plate 947 extends out of the outside of the groove 921, and under the elastic restoring force of the first spring 944, the deposition plate 947 moves upward to abut against the limiting plate 947, completing the disassembly and assembly of the deposition plate 947;

[0097] Compared with the prior art, it is more convenient to clean the deposited sludge and other sundries. At the same time, it can well reduce the blockage effect of the sludge on the drainage pipe 14, improve the drainage efficiency, and prevent the overall waterproof effect from being affected due to poor roof drainage resulting in water accumulation.
