Description

Technical Field

[0001] This invention belongs to the field of roof waterproofing technology, specifically relating to a waterproofing structure for steel roof ridges and its waterproofing method. Background Technology

[0002] The waterproofing structure of a steel roof ridge is a comprehensive waterproofing system involving multiple aspects such as design, material selection, construction technology, and post-construction maintenance. When designing the waterproofing system for the roof and ridge, the rainwater system should be designed strictly according to specifications, and overflow measures should be included. Detailed drawings should also be provided for details such as the edging of windows, the flashing of the ridge, and the internal and external corners to prevent rainwater leakage. Considering the thermal expansion and contraction characteristics of steel structure roofs, a suitable roofing system should be selected. For example, a floating roof structure can be chosen, with roof panels horizontally interlocked (i.e., standing seam seams) and vertically connected using a sandwich-like compression method. The overlap length of the roof panels should be no less than 40mm. This structural system is sliding, has good sealing, excellent waterproofing, and strong wind resistance.

[0003] Problems with existing technology:

[0004] However, in existing common roof design and installation methods, the connection and assembly are mostly achieved by screws or glue. However, the installation method of bolts can easily cause damage to the roof structure, while the glue method can cause the glue to age over time, resulting in detachment and separation. Moreover, the bonding effect also varies depending on the quality of different glues, causing the installed roof to leak water and be drafty, and the later maintenance costs are also high. Summary of the Invention

[0005] The purpose of this invention is to provide a waterproof structure and method for a steel roof ridge, which enables the assembly of the roof structure and ensures that the installation structure is stable and not prone to aging or deformation.

[0006] The specific technical solution adopted by this invention is as follows:

[0007] A steel roof ridge waterproofing structure includes a ridge cover and a second steel tile installed on the top of the main frame. A ridge beam is provided at the bottom of the ridge cover. The common end of a plurality of second steel tiles is installed on the top of the ridge beam. The second steel tiles are clamped and installed by a through strip and the top surface of the ridge beam.

[0008] Multiple second steel tiles are spliced ​​together, and the sides of the second steel tiles facing the bottom are provided with inward rolled plates;

[0009] Located at the second steel tile splicing position, a strip-shaped splicing groove beam is provided at the corresponding position on the top of the main frame. A curved inward flipping side plate is provided on the top of the splicing groove beam, and a third rough surface coupled to the contact surface of the inner roll plate is provided on the opposite surfaces of the two inward flipping side plates.

[0010] One end of the splicing channel beam is fixedly installed at the bottom of the roof ridge, and the bottom of the splicing channel beam is adjustablely installed at the top of the main frame through a double beam connector.

[0011] The two inwardly flipped side plates on both sides clamp two adjacent inwardly rolled plates.

[0012] The main frame is provided with at least one set of main beams at the top, and multiple secondary beams are fixedly installed on the top of the multiple main beams, and multiple beam frames are fixedly installed on the top of the secondary beams.

[0013] Multiple double-beam connectors are fixedly installed on the top of the beam frame, penetrating the first steel tile and the filling layer, and are fixedly installed with the splicing groove beam.

[0014] The beam frame is provided with extension plates on both sides of the top.

[0015] The double beam connector includes a clamp and an adjusting rod that are threaded together. A first clamping block is fixedly connected to the bottom of the adjusting rod. A second clamping block is provided at the top of the first clamping block and is sleeved with the adjusting rod. The second clamping block and the first clamping block clamp the two side extension plates. A first threaded pressure ring that is threadedly connected to the adjusting rod is abutted at the top of the second clamping block.

[0016] The adjusting rod is spliced ​​with opposite side clamping blocks, and at least one clamping plate is provided at the bottom of the side clamping blocks. The clamping plate is provided with first rough surfaces on both sides for clamping on both sides of the extension plate.

[0017] An annular sleeve is provided on one side of the adjacent side clamping block. A positioning collar is interference-fitted on the outside of the sleeve. A second threaded pressure ring is threaded on the outside of the adjusting rod. The second threaded pressure ring presses against the top of the opposite sleeve, causing the side clamping block to bend and drive the first rough surface on both sides to press against the sides of the extension plate.

[0018] The splicing beam has inwardly curved clamping grooves on both sides;

[0019] The inner side of the top of the chuck is provided with a locking block that is coupled and engaged inside the chuck groove.

[0020] The splicing channel beam is open at both ends, and an air vent is inserted at one end;

[0021] The ridge beam is fixedly installed on the top of the main beam. One end of the ridge beam has an air inlet, which is connected to multiple air outlets on the side. The other end of the splicing groove beam extends through a baffle plate, and the bottom of the baffle plate extends to the top of the water collection tank.

[0022] Multiple beam fixing clamps are provided at the bottom of both sides of the top of the ridge beam. The beam fixing clamps are used to fix the ends of the splicing groove beam.

[0023] The filling layer includes a first pad layer adhered to the top of the first steel tile, and a heat insulation layer, a second pad layer and a waterproof layer are sequentially disposed on the top of the first pad layer.

[0024] A method for waterproofing the ridge of a steel structure roof, comprising the following steps:

[0025] S1. Obtain the slope and length of the top surface of the main beam, and prefabricate the beam frame, first steel tile, filling layer, splicing groove beam and second steel tile of the corresponding size for installation on the top of the main beam;

[0026] S2, and install multiple double beam connectors evenly distributed on the top of the beam frame, and disassemble and slide the clamps on the top of the double beam connectors onto the splicing groove beam;

[0027] S3. After positioning the double beam connectors and the beam frame, the first steel tile and filling layer are fitted onto multiple double beam connectors, and the clamps and adjusting rods are threaded on. The ends of the splicing groove beams are then installed on the ridge beams using beam fixing clamps, thereby achieving the installation of the splicing groove beams.

[0028] S4. Then, the second steel tile is assembled in sequence, and the side of the second steel tile is clipped to the top of the splicing groove beam;

[0029] S5. Drill holes in the common end of the second steel tile corresponding to the pressure strip, and install bolts to position and install the second steel tile, and then cover the ridge cap.

[0030] S6. A water collection trough is installed at the other end of the splicing channel beam, below the bottom of the second steel tile, and a baffle is sleeved on the outside of the water collection trough, the second steel tile, and the splicing channel beam, and the bottom of the baffle is snapped into the side of the water collection trough.

[0031] S7. Wrap the edges of the second steel tile and install a drain pipe at the bottom of the water collection trough;

[0032] The seepage prevention method further includes the following steps:

[0033] A ceiling frame is installed at the bottom of the main beam, and a ceiling sealing film is installed at the bottom of the ceiling frame to form a sealed space between the ceiling sealing film and the second steel tile. An air pump installed at the top of the ceiling frame draws gas from the air inlet until it is discharged through the air outlet and splicing groove beam, so that the bottom of the second steel tile is under negative pressure.

[0034] The moisture inside the splicing channel beam is discharged with the airflow through air circulation;

[0035] The water vapor generated at the bottom of the second steel tile is discharged with the airflow using an air pump;

[0036] By using an air pump to create negative pressure at the bottom of the second steel tile and the top of the ceiling sealing film, the second steel tile forms a downward adsorption force, reducing the penetration of moisture.

[0037] The technical effects achieved by this invention are as follows:

[0038] This invention thickens the side of the second steel tile by inverting the inner rolled plate on its side, thereby increasing its hardness and resistance to deformation. The inward-turning side plate inside the splicing channel beam abuts against the inner rolled plate, and a stable connection is achieved by setting a third rough surface that interlocks with each other. This reduces the use of glue and avoids aging and corrosion problems caused by glue.

[0039] In this invention, an air inlet on one side of the ridge beam is connected to at least one fan or negative pressure fan via an air pipe to facilitate the exchange of gas between the bottom of the main beam and the outside air, and to expel humid gas. Attached Figure Description

[0063] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0064] like Figure 1-7 As shown, a steel roof ridge waterproofing structure includes a ridge cover 4 and a second steel tile 5 installed on the top of the main frame 1. A ridge beam 3 is provided at the bottom of the ridge cover 4. The common end of a plurality of second steel tiles 5 is installed on the top of the ridge beam 3. The second steel tiles 5 are clamped and installed on the top surface of the ridge beam 3 by a through strip 34.

[0065] Combination Figure 11 As shown, multiple second steel tiles 5 are spliced ​​together. The side of the second steel tile 5 facing the bottom is provided with an inner rolled plate 51. At the splicing position of the second steel tile 5, a strip-shaped splicing groove beam 7 is provided at the corresponding position on the top of the main frame 1. The top of the splicing groove beam 7 is provided with a curved inner flip side plate 72. The opposite surfaces of the two inner flip side plates 72 are provided with a third rough surface 73 that is coupled with the contact surface of the inner rolled plate 51. The two inner flip side plates 72 clamp two adjacent inner rolled plates 51.

[0066] Furthermore, one end of the splicing channel beam 7 is fixedly installed at the bottom of the roof ridge cover 4, and the bottom of the splicing channel beam 7 is adjustablely installed at the top of the main frame 1 through the provided double beam connector 8.

[0067] Based on the above structure, its working principle is as follows:

[0068] The connection between the beam frame 6 and the splicing groove beam 7 is achieved through the double beam connector 8, and the splicing groove beam 7 is further fixed by fixing one end of it to the ridge beam 3. When assembling two adjacent second steel tiles 5, the inward rolling plates 51 on both sides can thicken the sides of the second steel tiles 5, thereby increasing the hardness and deformation resistance of the sides of the second steel tiles 5. The inward rolling side plate 72 set inside the splicing groove beam 7 abuts against the inward rolling plate 51, and the third rough surface 73 that interlocks and fits together is set to achieve a stable connection, which reduces the use of glue and avoids aging and corrosion problems caused by glue.

[0069] Optionally, the third rough surface 73 is located on one side of the inward flipping side plate 72 and is set as a triangular protrusion with a vertical edge, and the vertical edge is located on the bottom side of the triangular protrusion. This facilitates the insertion and installation of the second steel tile 5 and enables the corresponding surface of the inner rolled plate 51 to be snapped together, preventing the inner rolled plate 51 from falling off, especially during windy weather when it may shake and loosen. In addition, if a second steel tile 5 is damaged and there is no snap-fit ​​between the inward flipping side plate 72 and the inner rolled plate 51, it can be replaced by removing the baffle at one end of the damaged second steel tile 5 and pulling out the damaged second steel tile 5.

[0070] Optionally, when the surface of the third rough surface 73 is mostly irregular rough surface, the connection position of the adjacent second steel tile 5 can be positioned by the elastic separation between the inner roll plate 51 and the body of the second steel tile 5, and by the squeezing of the inner flip side plates 72 on both sides. This method of installation and replacement is simpler, but the applicable scenarios are limited, such as the installation location should be in an area with low wind force all year round, or on a roof with other protective structures on top.

[0071] Furthermore, when two adjacent second steel tiles 5 are spliced ​​together, there will be gaps. These gaps are used to introduce rainwater into the splicing channel beam 7, and the water flows out through the lower horizontal end of the splicing channel beam 7 and into the water collection trough 2 for discharge.

[0072] Optionally, by setting a waterproof layer or performing anti-corrosion treatment on the inner side of the splicing channel beam 7, the service life of the splicing channel beam 7 can be extended, and the structural stability of the splicing channel beam 7 can be further improved. In addition, after the fixing and clamping effect of the splicing channel beam 7 weakens, by checking the looseness of the second steel tile 5, the splicing channel beam 7 or the installation structure of the splicing channel beam 7 can be maintained through maintenance methods, including replacing the splicing channel beam 7 or reinforcing the installation structure of the splicing channel beam 7.

[0073] See attached document Figure 1 and Figure 2 The main frame 1 has at least one set of main beams 13 at the top, and multiple secondary beams 14 are fixedly installed on the top of the multiple main beams 13. Multiple beam frames 6 are fixedly installed on the top of the secondary beams 14.

[0074] Furthermore, multiple double-beam connectors 8 are fixedly installed on the top of the beam frame 6, and pass through the first steel tile 10 and the filling layer 9, and are fixedly installed with the splicing groove beam 7.

[0075] The splicing channel beam 7 is set in a direction parallel to the side of the second steel tile 5.

[0076] According to the above structure, an outer wall 11 is installed on the outside of the main frame 1. The outer wall 11 can be either a cement wall or a metal plate wall. Its thickness affects the width of the water collection tank 2. The drain pipe 12 is installed on the surface of the outer wall 11 by means of pipe clamps and screws.

[0077] Example 11:

[0078] See attached document Figure 3-7 and Figure 10 The splicing channel beam 7 is connected at both ends, and an air vent 32 is inserted at one end.

[0079] Furthermore, the ridge beam 3 is fixedly installed on the top of the main beam 13. Its installation methods include, but are not limited to, connection by welding and fixed installation by bolt and nut assembly. The specific connection methods are existing technologies and will not be described in detail here.

[0080] Furthermore, one end of the ridge beam 3 is provided with an air inlet 31, which is connected to multiple air outlets 32 located on the side. The other end of the splicing trough beam 7 extends through the insert baffle 21, and the bottom of the baffle 21 extends to the top of the water collection trough 2. The air inlet 31 on one side of the ridge beam 3 is connected to at least one fan or negative pressure fan through an air pipe to realize the exchange of air between the bottom of the main beam 13 and the outside air and the discharge of humid air. The air inlet 31 is located outside the end face of the ridge beam 3, or it can be located at the bottom of the ridge beam 3. The air inlet 31 is connected to the air outlet 32 ​​through a conduit or by directly setting a channel inside the ridge beam 3.

[0081] Furthermore, multiple beam fixing clamps 33 are provided at the bottom of both sides of the top of the ridge beam 3. The beam fixing clamps 33 are used to fix the ends of the splicing groove beam 7.

[0082] According to the above structure, in addition to being fixed and connected to the double beam connector 8 between the beam frame 6, the splicing channel beam 7 is further connected by the beam fixing clamp 33. The connection method is to embed or weld studs inside the ridge beam 3, install the end of the splicing channel beam 7 between multiple studs, squeeze the splicing channel beam 7 with a pressure plate, and press and fix the splicing channel beam 7 with at least two layers of bolts.

[0083] Example 1 and 2:

[0084] See attached document Figure 3-7 and Figure 10 For details, please refer to Figure 6 Compared to Embodiment 1, multiple ceiling racks 15 are installed inside the main frame 1 and below the main beam 13. A ceiling sealing film 16 is installed on the surface of the ceiling rack 15 to isolate the upper and lower spaces of the ceiling rack 15. At this time, the air inlet 31 is connected to at least one fan or negative pressure fan through an air pipe to realize the exchange of gas between the bottom of the main beam 13 and the outside gas. The fan or negative pressure fan is installed above the ceiling rack 15 to realize the suction and discharge of gas from the top of the ceiling sealing film 16. During the operation of the fan or negative pressure fan, the top of the ceiling sealing film 16 is in a negative pressure state, which can realize the negative pressure attraction of the second steel tile 5, and improve the installation and adhesion of the second steel tile 5. Its adsorption capacity depends on the power of the fan or negative pressure fan, the sealing degree of the connection between the second steel tile 5 and the splicing groove beam 7, and the airtightness of the space at the top of the ceiling sealing film 16.

[0085] In addition, the ceiling sealing film 16 can also intercept falling objects such as dust;

[0086] Furthermore, in the above embodiments one and two, by exchanging the air flow at the bottom of the main beam 13, the ice and snow on the top of the second steel tile 5 can be melted by the internal room temperature, thereby improving the melting efficiency and reducing the pressure on the second steel tile 5.

[0087] Example 21:

[0088] See attached document Figure 8-10 The top two sides of the beam frame 6 are provided with extension plates 61.

[0089] Furthermore, the double beam connector 8 includes a clamp 81 and an adjusting rod 83 that are threadedly connected to each other. A first clamping block 84 is fixedly connected to the bottom of the adjusting rod 83. A second clamping block 85 is provided on the top of the first clamping block 84 and is sleeved with the adjusting rod 83. The second clamping block 85 and the first clamping block 84 clamp the two side extension plates 61. A first threaded pressure ring 90 that is threadedly connected to the adjusting rod 83 is abutted on the top of the second clamping block 85.

[0090] The chuck 81 and the adjusting rod 83 are connected by a threaded structure. A threaded rod is provided at the bottom of the chuck 81 for threaded installation inside the adjusting rod 83 to adjust the extension length of the adjusting rod 83. In addition, the other end of the adjusting rod 83 is also set as two sections, not shown in the figure, and is also set as a threaded connection to cooperate with the installation of the chuck 81. Because the chuck 81 is pre-installed on the splicing groove beam 7 during the installation process, the installation needs to be achieved by rotating the adjusting rod 83.

[0091] Based on the above structure, its working principle is as follows:

[0092] During installation, the first clamping block 84 is inserted laterally into the interior of the two side extension plates 61. Then, the first clamping block 84 is rotated so that the second rough surface 841 abuts against the bottom of the extension plate 61, and the second clamping block 85 abuts against the other side of the extension plate 61. Then, the first threaded pressure ring 90 is rotated to clamp the extension plate 61 with the second clamping block 85 and the first clamping block 84, thereby achieving the installation and positioning of the bottom side of the double beam connector 8. The installation is achieved by connecting the beam frame 6 and the splicing groove beam 7 through the double beam connector 8.

[0093] Example 22:

[0094] To further improve the connection stability between the double-beam connector 8 and the beam frame 6, the following solution is used:

[0095] See attached document Figure 8-10 The adjusting rod 83 is spliced ​​with opposite side clamping blocks 86. At least one clamping plate 89 is provided at the bottom of the side clamping block 86. The clamping plate 89 is provided with first rough surfaces 891 on both sides for clamping on both sides of the extension plate 61.

[0096] Furthermore, an annular sleeve 88 is provided on one side of the adjacent side clamping block 86. A positioning collar 87 is interference-fitted on the outside of the sleeve 88. A second threaded pressure ring 91 is threaded on the outside of the adjusting rod 83. The second threaded pressure ring 91 presses the top of the opposite sleeve 88, causing the side clamping block 86 to bend and drive the first rough surfaces 891 on both sides to press the two sides of the extension plate 61.

[0097] Based on the above structure, its working principle is as follows:

[0098] By installing the clamping plate 89 inside the extension plate 61 and rotating it, the two sides of the first rough surface 891 are respectively installed on both sides of the extension plate 61. Then, the positioning collar 87 is sleeved on the two sleeves 88 to achieve the initial positioning of the two side clamping blocks 86. Then, by rotating the second threaded pressure ring 91, the top of the sleeve 88 is squeezed, so that the first rough surface 891 on the upper side of the clamping plate 89 is squeezed with the top surface of the extension plate 61, which is used to improve the connection stability between the double beam connector 8 and the beam frame 6.

[0099] Then, the second threaded pressure ring 91 is rotated further to make the side clamping block 86 bend. At this time, the first rough surface 891 on both sides is pressed against the upper and lower surfaces of the extension plate 61, which can further improve the connection stability between the double beam connector 8 and the beam frame 6 and prevent the slippage between the first rough surface 891 and the extension plate 61.

[0100] See attached document Figure 10 and Figure 11 The splicing beam 7 has inwardly curved clamping grooves 71 on both sides. The connection point between the splicing beam 7 and the vent 32 is a welded part, used to adapt to roof ridges of different widths. The end of the clamping groove 71 is located at the other end of the splicing beam 7. Figure 11 As shown, after multiple clamps 81 are installed, iron sheets or plugs are welded to the end of the clamping groove 71 to prevent rainwater or airflow from entering the bottom of the second steel tile 5.

[0101] In addition, at the bottom of the curved part of the inner rolled plate 51, there is a filler plate 52 welded to it. The filler plate 52 abuts against the top of the splicing channel beam 7. The filler plate 52 can make the side of the second steel tile 5 more rigid and prevent it from curling. By adjusting the thickness of the filler plate 52, the insertion depth of the inner rolled plate 51 and the splicing channel beam 7 can be adjusted.

[0102] Furthermore, the inner side of the top of the chuck 81 is provided with a locking block 82 that is coupled and locked inside the chuck groove 71.

[0103] According to the above structure, the coupling method between the card block 82 and the clamping groove 71 is that the two are tightly fitted or interference fit, in order to avoid loosening between the double beam connector 8 and the splicing groove beam 7 after installation.

[0104] See attached document Figure 12 The filling layer 9 includes a first pad 101 adhered to the top of the first steel tile 10, and a heat insulation layer 94, a second pad 92 and a waterproof layer 93 are sequentially disposed on the top of the first pad 101.

[0105] In the above structure, the first pad 101 is used to improve the adhesion of the heat insulation layer 94. On the one hand, the first pad 101 can prevent the heat insulation layer 94 from corroding the first steel tile 10. On the other hand, it can prevent defects in the heat insulation layer 94 itself after filling, thus improving the airtightness. At the position where the double beam connector 8 is installed, the first pad 101 is used to isolate the direct contact between the double beam connector 8 and the heat insulation layer 94, thereby indirectly protecting the double beam connector 8.

[0106] Furthermore, the insulation layer 94 includes existing insulation materials or other expandable filling materials with internal air bubbles. Depending on the setting position of the main frame 1, an insulation layer 94 with specific functions can be selected. The second padding layer 92 is a padding layer used to cover and insulate the insulation layer 94, or the second padding layer 92 can be set to the same material as the first padding layer 101.

[0107] Furthermore, the waterproof layer 93 is a waterproof layer covering the surface of the second padding layer 92. It can be a membrane or a sprayed material layer. After the installation of the double beam connector 8 and the filling layer 9, a support can be set in the gap between them to achieve a breathable effect. It is used in conjunction with Embodiments 1 and 2 to achieve air circulation. It can also be an expanding filling material to improve the integrity of the filling layer 9. In this case, it can be used in conjunction with Embodiment 1 to achieve the exchange of gases inside and outside the main frame 1.

[0108] In this application, in addition to the connection methods already shown above, the main beam 13 and the secondary beam 14, the secondary beam 14 and the beam frame 6, and the first steel tile 10 and the beam frame 6 can also be directly installed by welding, bolt and nut assembly with U-shaped clamp, or bolt and nut assembly. The specific installation and connection methods are readily conceived and implemented by those skilled in the art in the prior art, so they will not be elaborated further here.

[0109] A method for waterproofing the ridge of a steel structure roof includes the following steps:

[0110] S1. Obtain the slope and length of the top surface of the main beam 13, and prefabricate the beam frame 6, the first steel tile 10, the filling layer 9, the splicing groove beam 7 and the second steel tile 5 of the corresponding size for installation on the top of the main beam 13;

[0111] S2, and install multiple double beam connectors 8 evenly distributed on the top of the beam frame 6, and disassemble and slide the clamps 81 on the top of the double beam connectors 8 onto the splicing groove beam 7.

[0112] S3. After positioning the double beam connector 8 and the beam frame 6, the first steel tile 10 and the filling layer 9 are sleeved on the multiple double beam connectors 8, and the clamp 81 and the adjusting rod 83 are threaded on. The end of the splicing groove beam 7 is installed on the ridge beam 3 through the beam fixing clamp 33, thereby realizing the installation of the splicing groove beam 7.

[0113] S4. Then, the second steel tile 5 is assembled in sequence, and the side of the second steel tile 5 is clipped to the top of the splicing groove beam 7.

[0114] S5. Drill holes in the common end of the second steel tile 5 corresponding to the pressure strip 34, and install bolts to achieve the positioning and installation of the second steel tile 5, and then cover the ridge cap 4.

[0115] S6. At the other end of the splicing channel beam 7, a water collection trough 2 is installed below the bottom of the second steel tile 5, and a baffle 21 is sleeved on the outside of the water collection trough 2, the second steel tile 5, and the splicing channel beam 7, and the bottom of the baffle 21 is snapped onto the side of the water collection trough 2.
