Description

Technical Field

[0001] The invention belongs to the technical field of roof leakage prevention, and in particular relates to a steel structure roof ridge leakage prevention structure and an anti-seepage method thereof. Background Art

[0002] The anti-leakage structure of the steel roof ridge is a comprehensive waterproof system, which involves design, material selection, construction technology and later maintenance. For the waterproof system of the roof and ridge, the roof rainwater system should be designed in strict accordance with the specifications, and overflow measures should be set. At the same time, detailed drawings of details such as the edging of the upper and lower eaves of the windows, the flashing of the ridge and the Yin-Yang corners should be supplemented to prevent rainwater leakage. In view of the characteristics of thermal expansion and contraction of the steel structure roof, the roof system should be reasonably selected. For example, the roof structure can choose a floating roof. The roof panel is locked horizontally with a bite-type lock (i.e., vertical seam locking) and is linked vertically by sandwich extrusion. At the same time, the roof overlap length should be not less than 40mm. This structural system is slidable, has good sealing, good waterproof effect and strong wind resistance.

[0063] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

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

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

[0066] Furthermore, one end of the spliced ​​trough beam 7 is fixedly installed at the bottom of the ridge top cover 4, and the bottom of the spliced ​​trough beam 7 is adjustably installed at the top of the main frame 1 through a double-beam connector 8.

[0067] According to the above structure, its working principle is:

[0068] Among them, the connection between the beam frame 6 and the spliced ​​trough beam 7 is realized through the double-beam connector 8, and the spliced ​​trough beam 7 is fixedly installed on the ridge beam 3 at one end to realize further fixed installation of the spliced ​​trough beam 7. When assembling two adjacent second steel tiles 5, the inner roll plates 51 on both sides are turned inward, so that the side edges of the second steel tiles 5 can be thickened, thereby increasing the hardness and deformation resistance of the side edges of the second steel tiles 5. The inner flip side plates 72 arranged inside the spliced ​​trough beam 7 are used to abut against the inner roll plates 51, and a third rough surface 73 that are mutually snap-fitted is provided to achieve a stable connection, reduce the use of glue, and avoid aging and corrosion problems caused by glue.

[0069] Optionally, the third rough surface 73 is located on one side of the inner flip side plate 72 and is configured as a triangular protrusion with a vertical edge, and the vertical edge is located on the bottom side of the triangular protrusion, which is convenient for the insertion and installation of the second steel tile 5, and realizes the card connection of the corresponding surface of the side of the inner roll plate 51, to prevent the inner roll plate 51 from falling off, especially in windy weather, and the loosening caused by shaking. In addition, when a piece of the second steel tile 5 is damaged, when the inner flip side plate 72 and the inner roll plate 51 are in a card connection, the damaged second steel tile 5 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 set as an irregular rough surface, the connection position of the adjacent second steel tile 5 is positioned through the elastic separation between the inner roll plate 51 and the second steel tile 5 body, and the extrusion of the inner flip side plates 72 on both sides. This type of installation and replacement is simpler, but the applicable scenarios are limited. For example, the installation location should be an area with low wind force all year round, or a roof with other protective structures on the top.

[0071] Furthermore, when two adjacent second steel tiles 5 are assembled and snap-fitted, there will be a gap, and the gap caused by the gap is used to introduce rainwater into the spliced ​​trough beam 7, and flow out through the lower horizontal end of the spliced ​​trough beam 7, and flow into the water collecting trough 2 for discharge.

[0072] Optionally, a waterproof layer is provided on the inner side of the spliced ​​trough beam 7 or an anti-corrosion treatment is performed to extend the service life of the spliced ​​trough beam 7 and further improve the stability of the structural installation of the spliced ​​trough beam 7. In addition, after the fixing effect of the spliced ​​trough beam 7 is weakened, the looseness of the second steel tile 5 can be checked and the spliced ​​trough beam 7 or the installation structure of the spliced ​​trough beam 7 can be maintained by maintenance methods, including replacement of the spliced ​​trough beam 7 or reinforcement of the installation structure of the spliced ​​trough beam 7.

[0073] See attached Figure 1 and Figure 2 At least one set of main beams 13 is provided on the top of the main frame 1, and multiple auxiliary beams 14 are fixedly installed on the top of the multiple main beams 13, and multiple beam frames 6 are fixedly installed on the top of the auxiliary beams 14.

[0074] Furthermore, a plurality of double beam connectors 8 are fixedly installed on the top of the beam frame 6 , and penetrate the first steel tile 10 and the filling layer 9 , and are fixedly installed with the spliced ​​trough beam 7 .

[0075] The spliced ​​channel beam 7 is arranged 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 is any one of a cement wall and a metal plate wall. Its setting thickness affects the setting width of the water collection tank 2. The installation method between the drain pipe 12 and the outer wall 11 is to fix it on the surface of the outer wall 11 through a pipe clamp and screws.

[0077] Embodiment 1:

[0078] See attached Figure 3-7 and Fig.10 The two ends of the splicing slot beam 7 are connected, and an air outlet 32 ​​is inserted at one end.

[0079] Furthermore, the ridge beam 3 is fixedly installed on the top of the main beam 13, and its installation method includes but is not limited to connecting by welding and fixing by bolt and nut assemblies. The specific connection method is the existing technology and will not be described in detail here.

[0080] Furthermore, an air inlet 31 is provided at one end of the ridge beam 3, and the air inlet 31 is connected with a plurality of air outlets 32 arranged on the side. The other end of the spliced ​​trough beam 7 extends through the plug-in baffle 21, and the bottom of the baffle 21 extends to the top of the sump 2. The air inlet 31 opened on one side of the ridge beam 3 is connected to at least one fan or a negative pressure fan through an air pipe, which is used to realize the exchange of gas at the bottom of the main beam 13 with the external gas and the discharge of humid gas. The air inlet 31 is arranged outside the end face of the ridge beam 3, and can also be arranged at the bottom of the ridge beam 3. The air inlet 31 is connected with the air outlet 32 ​​through a conduit or a channel directly arranged inside the ridge beam 3.

[0081] Furthermore, a plurality of beam fixing fixtures 33 are provided at the bottom of both sides of the top of the ridge beam 3 , and the beam fixing fixtures 33 are used to fix and install the ends of the spliced ​​trough beam 7 .

[0082] According to the above structure, the spliced ​​trough beam 7 is not only fixed and connected to the double beam connector 8 between the beam frame 6, but also further connected by fixing the beam fixing clamp 33. The connection method is to embed or weld studs inside the ridge beam 3, install the end of the spliced ​​trough beam 7 between multiple studs, and squeeze the spliced ​​trough beam 7 through a pressure plate, and realize the compression and fixation of the spliced ​​trough beam 7 through at least two layers of bolts.

[0083] Embodiment 1 and 2:

[0084] See attached Figure 3-7 and Fig.10 , please refer to Figure 6 Compared with the first embodiment, it is located inside the main frame 1 and installed below the main beam 13. A plurality of ceiling frames 15 are arranged. A layer of ceiling sealing film 16 is arranged on the surface of the ceiling frame 15 to isolate the upper and lower spaces of the ceiling frame 15. At this time, the air inlet 31 is connected to at least one fan or a negative pressure fan through an air pipe to realize the exchange of gas at the bottom of the main beam 13 and the external gas. The fan or the negative pressure fan is installed above the ceiling frame 15 to realize the suction and discharge of gas at the top of the ceiling sealing film 16. During the operation of the fan or the 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 attachment ability of the second steel tile 5. Its adsorption capacity depends on the power of the fan or the negative pressure fan, the sealing degree of the connection position between the second steel tile 5 and the splicing slot beam 7, and the sealing degree of the top space of the ceiling sealing film 16.

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

[0086] Furthermore, in the above-mentioned Embodiment 11 and Embodiment 12, by means of flow exchange of air at the bottom of the main beam 13, when ice and snow appear on the top of the second steel tile 5, the ice and snow can be melted by the internal room temperature, thereby improving the melting efficiency and reducing the pressure on the second steel tile 5.

[0087] Embodiment 21:

[0088] See attached Figure 8-10 Extension plates 61 are provided on both sides of the top of the beam frame 6.

[0089] Furthermore, the double-beam connecting member 8 includes a clamp 81 and an adjusting rod 83 that are threadedly connected to each other, a first clamp block 84 is fixedly connected to the bottom of the adjusting rod 83, a second clamp block 85 that is sleeved with the adjusting rod 83 is provided on the top of the first clamp block 84, the second clamp block 85 and the first clamp block 84 clamp the extension plates 61 on both sides, and the top of the second clamp block 85 abuts against a first threaded pressure ring 90 that is threadedly connected to the adjusting rod 83.

[0090] Among them, there is a threaded connection structure between the chuck 81 and the adjusting rod 83. A threaded rod is set at the bottom of the chuck 81 for threaded installation inside the adjusting rod 83 to adjust the telescopic length of the adjusting rod 83. In addition, the other end of the adjusting rod 83 is also set to two sections, which are not shown in the figure here, and are also set to be threaded connection for cooperating in the installation of the chuck 81. Because during the installation of the chuck 81, the chuck 81 is installed on the splicing slot beam 7 in advance, so it is necessary to achieve installation by rotating the adjusting rod 83.

[0091] According to the above structure, its working principle is:

[0092] During installation, the first clamp block 84 is horizontally inserted into the extension plates 61 on both sides, and then the first clamp block 84 is rotated so that the second rough surface 841 abuts against the bottom of the extension plate 61, and the second clamp block 85 abuts against the other side of the extension plate 61, and then the first threaded pressure ring 90 is rotated and installed so that the second clamp block 85 and the first clamp block 84 clamp the extension plate 61, thereby realizing the installation positioning on one side of the bottom of the double beam connector 8, and the installation is realized by connecting the beam frame 6 and the spliced ​​slot beam 7 through the double beam connector 8.

[0093] Embodiment 22:

[0094] In order 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 Figure 8-10 The outer side of the adjusting rod 83 is spliced ​​with a relative side clamping block 86, and at least one clamping plate 89 is extended from the bottom of the side clamping block 86. The two sides of the clamping plate 89 are respectively provided with a first rough surface 891 for clamping on both sides of the extension plate 61.

[0096] Furthermore, an annular hoop 88 is provided on one side of the adjacent side clamp block 86, and a positioning ring 87 is interference-fitted on the outer side of the hoop 88. A second threaded pressure ring 91 is threadedly installed on the outer side of the adjusting rod 83. The second threaded pressure ring 91 squeezes the top of the opposite hoop 88 to bend the side clamp block 86 and drives the first rough surfaces 891 on both sides to squeeze the two sides of the extension plate 61.

[0097] According to the above structure, its working principle is:

[0098] By installing the clamping plate 89 on the inner side of the extension plate 61 and rotating it, the two side surfaces of the first rough surface 891 are respectively installed on the two sides of the extension plate 61, and then the positioning ring 87 is sleeved on the two hoop sleeves 88 to achieve the initial positioning of the two side clamping blocks 86, and then the second threaded pressure ring 91 is rotated to squeeze the top of the hoop sleeve 88, 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, so as 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 further rotated to cause the side clamp block 86 to produce a bending effect. At this time, the first rough surfaces 891 on both sides are squeezed 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 avoid sliding between the first rough surface 891 and the extension plate 61.

[0100] See attached Fig.10 and Fig.11 , both sides of the splicing groove beam 7 are provided with clip grooves 71 bent inwardly, and the connection position of the splicing groove beam 7 with the air outlet 32 ​​is a welding part, which is used to adapt to ridges of different widths, and the end of the clip groove 71 at the other end of the splicing groove beam 7, Fig.11 As shown in , after multiple clamps 81 are installed at the end of the clamp groove 71, a sealed iron sheet or plug is welded to prevent rainwater or airflow from entering the bottom of the second steel tile 5.

[0101] In addition, a filling plate 52 welded to the bottom of the bent portion of the inner roll plate 51 is filled, and the filling plate 52 abuts against the top of the spliced ​​trough beam 7. The filling plate 52 can make the side of the second steel tile 5 harder to avoid curling. By adjusting the thickness of the filling plate 52, the insertion depth of the inner roll plate 51 and the spliced ​​trough beam 7 can be adjusted.

[0102] Furthermore, a clamping block 82 is provided on the inner side of the top of the clamping head 81 and is coupled and clamped in the clamping groove 71 .

[0103] According to the above structure, the coupling mode between the clamping block 82 and the clamping groove 71 is that the two are tightly fitted or interference fit, so as to avoid looseness between the double beam connector 8 and the spliced ​​groove beam 7 after installation.

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

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

[0106] Furthermore, the thermal insulation layer 94 includes existing thermal insulation materials or other expandable filling materials with bubbles inside. The thermal insulation layer 94 with specific functions can be selected according to the setting position of the main frame 1. The second cushion layer 92 is a cushion layer used to cover the insulating layer 94, or the second cushion layer 92 can be set to the same material as the first cushion layer 101.

[0107] Furthermore, the waterproof layer 93 is a waterproof layer covering the surface of the second cushion layer 92, which can be a layer of coating or a layer of sprayed material. A support can be set in the gap between the double-beam connector 8 and the filling layer 9 after installation to achieve a breathable effect. It is used in conjunction with embodiments one and two to achieve air circulation. It can also be an expandable filling material to enhance the integrity of the filling layer 9. At this time, it can be used in conjunction with embodiment one to achieve the exchange of gas inside and outside the main frame 1.

[0108] In the present application, in addition to the connection methods shown above, such as between the main beam 13 and the auxiliary beam 14, the auxiliary beam 14 and the beam frame 6, and the first steel tile 10 and the beam frame 6, welding, bolt and nut assemblies in combination with U-shaped clamps, and bolt and nut assemblies can also be used for direct installation.
