Description

Technical Field

[0001] This invention relates to a building construction method, and more specifically, to a construction method for a multi-directional guided roof rainproof, drainage and ventilation structure. Background Technology

[0002] With the rapid advancement of urbanization, building construction is becoming increasingly complex. However, the drainage structure during roof construction remains an indispensable part of the construction industry. It can prevent rainwater from accumulating on the roof in rainy weather, thereby preventing rainwater from penetrating the roof's waterproof layer and causing leaks, which would affect the residents' living experience and increase the cost of later repairs.

[0003] A drainage structure is a layer installed during roof construction to drain rainwater and allow air to escape. It is usually a hollow structure with a certain slope and drainage pipes inside. The sides of the drainage pipes are filled with granular stones to enhance the structural strength of the drainage layer. This allows the roof structure to drain and vent while maintaining good structural strength.

[0004] Currently, waterproofing layers on the market typically use a layered structure consisting of a slope-forming layer, an insulation layer, and a surface layer for fixation. While this can meet basic drainage needs, the overall drainage and ventilation performance of the structure is poor. The other internal layers are prone to accumulating moisture, which can cause the roof structure to swell and fail due to prolonged moisture buildup. Furthermore, the long-term retention of moisture can cause the roof waterproofing layer to bulge, crack, and peel off, leading to roof leaks. This not only affects the normal use of the building but also significantly increases the cost of later maintenance. In addition, the roof drainage layer is only reinforced by filling with granular stones, resulting in low overall structural strength. In extreme weather conditions, this can easily lead to roof cracking and create safety hazards. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a construction method for a multi-directional guided roof rainproof drainage and ventilation structure that can effectively drain and vent, has high overall structural strength, and is convenient for overall roof construction.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a construction method for a multi-directional guided roof rainproof drainage and ventilation structure, comprising the following steps: S1, according to the required roof dimensions, pre-processing the corresponding size drainage installation component, the processing method being: taking the midpoint of the long side and the wide side of the drainage installation component as a reference, tilting towards both ends of the corresponding side, thereby forming an inclined ramp facing the outer periphery of the drainage installation component on the top of the drainage installation component, and the inclined ramp is uniformly set along the width or length of the drainage installation component on the top of the drainage installation component, the horizontally set inclined ramp and the vertically set inclined ramp intersect each other and form a support column at the intersection; S2. Support pipes and support frames are sequentially installed inside the inclined ramp. The support pipes are positioned opposite each other in the middle of the inclined ramp and extend along the length of the inclined ramp. Drainage and exhaust outlets are formed at the edge of the drainage installation. Meanwhile, support frames are sequentially installed along the length of the support pipes. The support frames are positioned between adjacent support columns and connect the midpoints of adjacent support columns. The support frames are perpendicular to the support pipes. S3. When setting up the support frame, adjust the height of the support frame to make the height of each support frame consistent. After the support frame is set up, adjust the length of the baffle installed on the support frame based on the position of the support frame. S4. After the baffle is installed, the bearing disc on the connector is released from the rotating device, so that the baffle can rotate relative to the connecting rod. S5. When the baffle rotates, the baffle can enter the interior of the support tube through the V-shaped groove pre-set on the support tube. The lower end of the V-shaped groove does not collide with the rotation path of the baffle, while the higher end does collide with the rotation path of the baffle. This allows a portion of the baffle to extend into the interior of the support tube after the baffle is set vertically, and the baffle can contact the support tube. S6. After the baffle is installed, weld the baffle to the support pipe. After welding, fill the inclined ramp with filling material so that the height of the filling material is at the same level as the support column. S7. Lay a waterproof membrane on the surface of the completed drainage installation to prevent leakage during the construction of other top layers. S8. After the roof paving is completed, waterproofing treatment is carried out to complete the roof construction.

[0007] The invention is further configured such that: the drainage and venting structure includes a roof, the roof is provided with drainage installation components, the drainage installation components include a plurality of drainage channels, and a support column is provided between each drainage channel; the drainage channels are configured to form an inclined ramp from the center of the roof to the edge of the roof; a support pipe matching the inclination angle of the inclined ramp is provided in the inclined ramp; a filling material is also provided between the support pipe and the support column; a plurality of support frames are provided along the length of the inclined ramp; after each support frame is installed in the inclined ramp, the top of the support frame has a protrusion with a height greater than the top of the support column.

[0008] Preferably, the support frame includes a connecting rod disposed at the protrusion, the connecting rod being fixedly connected to the protrusion at the top of the support frame, and a rotating device is also provided on the connection part between the connecting rod and the support frame.

[0009] Preferably, the rotating device includes a connector removably mounted on the connecting rod, and a baffle detachably connected to the connector and extending away from the protrusion of the support frame, the baffle being configured to abut against the support tube in the inclined ramp after the support frame is installed.

[0010] Preferably, the support tube is a hollow structure, and the position of the support tube where the baffle is located is also provided with a V-shaped groove. The baffle extends into the interior of the support tube through the V-shaped groove and is welded to the V-shaped groove at both ends.

[0011] Preferably, the connecting rod is provided with a positioning hook, and the connector is also provided with a protruding piece. The protruding piece is configured to engage with the positioning hook to form a fixed installation of the connector, and the positioning hook can be pushed away from the protruding piece to disassemble the connector.

[0012] Preferably, the rotating device further includes a rotating rod, which passes through the middle of the rotating device and is rotatably mounted on the connecting rod so that the connector of the rotating device is rotatably mounted on the connecting rod. The length of the baffle on the connecting rod is set such that after the baffle is vertically set, the bottom of the baffle is connected to the top of the support tube.

[0013] Preferably, the connector further includes a bearing disc for frictionally engaging the connector and for tightening or loosening the rotating device to adjustably connect the baffle to the rotating device.

[0014] By adopting the above technical solution, the beneficial effects are as follows: 1. The drainage installation component of this application integrates the functions of drainage channel and strength support in a single component. The drainage channel is inclined, allowing rainwater to drain naturally by gravity, improving the drainage efficiency of the roof structure. Furthermore, the drainage channel is radially distributed with the center of the roof as a reference, enabling rapid drainage of rainwater, preventing moisture leakage within the insulation layer, extending the building's service life, and reducing subsequent maintenance costs. Simultaneously, the support columns are positioned between the intersecting drainage channels, providing stable vertical support for the overall roof structure, significantly improving the overall structural strength of the roof. Additionally, a system is installed inside the inclined ramp... The hollow support pipe, with its matching inclination angle to the drainage channel, provides drainage and ventilation channels for the roof while improving its strength. Furthermore, by installing several support frames along the length of the inclined ramp, each frame having a protrusion higher than the top of the support column after installation, effective support and positioning are provided when a waterproof membrane needs to be laid after the support frames are installed. This prevents sagging due to gravity during subsequent construction, ensuring the long-term reliable operation of the roof drainage system. The hollow design of the support pipe also allows for ventilation while draining water, enabling the orderly discharge of moisture from the roof structure layer and preventing dampness and expansion of the structure.

[0015] 2. Furthermore, the connector of this application is detachably installed by inserting a protruding piece into the positioning groove on the connecting rod. The protruding piece can quickly disassemble the connector after being pushed away from the positioning groove. At the same time, the connector can rotate relative to the connecting rod by passing a rotating rod through the rotating device. This allows the baffle to flexibly adjust the deflection angle according to the specific installation position of the support frame in the inclined ramp. The bearing disc is used to frictionally engage the connector to tighten or loosen the rotating device, realizing stepless adjustment and instant locking of the baffle angle. This allows the support frame to be adjusted and repositioned according to actual needs during construction, ensuring construction accuracy and efficiency. The baffle and connector are detachably connected and extend away from the protruding part of the support frame, i.e., the support pipe. After the support frame is installed, it abuts against the support pipe in the inclined ramp, thereby limiting the relative position of the support pipe and the support frame before filling, preventing the support pipe or support frame from shifting during the filling process, ensuring that the drainage channel will not change due to environmental influences, and achieving high construction accuracy and efficiency.

[0016] 3. Simultaneously, this application incorporates a V-shaped groove structure within the support pipe. A baffle extends into the support pipe through the V-shaped groove, forming a gas and liquid channel. Specifically, the support pipe has a V-shaped groove at the location where the baffle is located. The baffle extends into the support pipe through the V-shaped groove and is welded to the V-shaped groove at both ends. This structure provides high support strength between the baffle and the support pipe, preventing weakened waterproofing performance due to connection failure. Furthermore, the support pipe structure can be configured to slope towards the center from both ends at its top. After roof construction, during rainwater leakage, the top of the support pipe and the baffle can guide the accumulated water, allowing most of the rainwater to enter the support pipe and move along it to drain. The baffle's extension into the support pipe provides high bonding strength, and the V-shaped groove structure effectively collects rainwater and strengthens the cross-sectional strength of the support pipe, preventing deformation under roof loads and further improving the structural reliability of the drainage channel.

[0017] 4. Furthermore, in this application, the construction method uses the center of the long / wide side of the drainage installation component as a reference to tilt and process the corresponding two ends to form several inclined ramps, and forms support columns at the intersection of the transverse and longitudinal ramps, ensuring the symmetry and uniform distribution of the drainage channels set in the drainage installation component. After the support frame is set, the rotating device is released by the bearing disc and the length and angle of the baffle are adjusted based on the actual position of the support frame, so that the baffle can contact the support pipe after being set vertically, which can effectively improve the processing accuracy. After the baffle is welded, the filling material is set in the inclined ramp so that the filling height is at the same level as the support column, ensuring the flatness of the subsequent structure installation and greatly reducing the risk of leakage during subsequent use.

[0019] Reference Figures 1 to 3 The present invention provides a further description of an embodiment of a multi-directional guided roof rainproof, drainage and venting structure.

[0020] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature.

Therefore, the exemplary term “down” can encompass both up and down orientations.

[0021] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0022] A construction method for a multi-directional guided roof rainproof drainage and ventilation structure includes the following steps: S1. Pre-processing the drainage installation parts of the corresponding size according to the required roof size. The processing method is as follows: taking the midpoint of the long side and the wide side of the drainage installation part as a reference, tilting towards both ends of the corresponding side, thereby forming an inclined ramp facing the outer periphery of the drainage installation part on the top of the drainage installation part. The inclined ramp is evenly set along the width or length of the drainage installation part on the top of the drainage installation part. The horizontally set inclined ramp and the longitudinally set inclined ramp intersect each other and form a support column at the intersection. S2. Support pipes and support frames are sequentially installed inside the inclined ramp. The support pipes are positioned opposite each other in the middle of the inclined ramp and extend along the length of the inclined ramp. Drainage and exhaust outlets are formed at the edge of the drainage installation. Meanwhile, support frames are sequentially installed along the length of the support pipes. The support frames are positioned between adjacent support columns and connect the midpoints of adjacent support columns. The support frames are perpendicular to the support pipes. S3. When setting up the support frame, adjust the height of the support frame to make the height of each support frame consistent. After the support frame is set up, adjust the length of the baffle installed on the support frame based on the position of the support frame. S4. After the baffle is installed, the bearing disc on the connector is released from the rotating device, so that the baffle can rotate relative to the connecting rod. S5. When the baffle rotates, the baffle can enter the interior of the support tube through the V-shaped groove pre-set on the support tube. The lower end of the V-shaped groove does not collide with the rotation path of the baffle, while the higher end does collide with the rotation path of the baffle. This allows a portion of the baffle to extend into the interior of the support tube after the baffle is set vertically, and the baffle can contact the support tube. S6. After the baffle is installed, weld the baffle to the support pipe. After welding, fill the inclined ramp with filling material so that the height of the filling material is at the same level as the support column. S7. Lay a waterproof membrane on the surface of the completed drainage installation to prevent leakage during the construction of other top layers. S8. After the roof paving is completed, waterproofing treatment is carried out to complete the roof construction.

[0023] The drainage and venting structure includes a roof 1, on which a drainage installation component 2 is provided. The drainage installation component 2 includes several drainage channels, and a support column 3 is provided between each drainage channel. The drainage channels are configured to form an inclined ramp 4 from the center of the roof 1 to the edge of the roof 1. A support pipe 5 matching the inclination angle of the inclined ramp 4 is provided inside the inclined ramp 4. A filling material is also provided between the support pipe 5 and the support column 3. Several support frames 6 are provided along the length of the inclined ramp 4. After each support frame 6 is installed in the inclined ramp 4, the top of the support frame 6 has a protrusion 61 with a height greater than the top of the support column 3.

[0024] Preferably, the support frame 6 includes a connecting rod 62 disposed at the protrusion 61, the connecting rod 62 being fixedly connected to the protrusion 61 at the top of the support frame 6, and a rotating device 63 being provided on the connection part between the connecting rod 62 and the support frame 6.

[0025] Preferably, the rotating device 63 includes a connector 631 that can be removably mounted on the connecting rod 62, and a baffle 632 that is detachably connected to the connector 631 and extends away from the protrusion 61 of the support frame 6. The baffle 632 is configured to abut against the support tube 5 in the inclined ramp 4 after the support frame 6 is installed.

[0026] Preferably, the support tube 5 has a hollow structure, and the support tube 5 is provided with a V-shaped groove at the position where the baffle 632 is provided. The baffle 632 extends into the interior of the support tube 5 through the V-shaped groove and is welded to the V-shaped groove at both ends.

[0027] Preferably, the connecting rod 62 is provided with a positioning hook 64, and the connector 631 is also provided with a protruding piece 65. The protruding piece 65 is configured to engage with the positioning hook 64 to form a fixed installation of the connector 631, and the positioning hook 64 can be pushed away from the protruding piece to disassemble the connector 631.

[0028] Preferably, the rotating device 63 further includes a rotating rod, which passes through the middle of the rotating device 63 and is rotatably mounted on the connecting rod 62 so that the connector 631 of the rotating device 63 is rotatably mounted on the connecting rod 62. The length of the baffle 632 on the connecting rod 62 is set such that after the baffle 632 is vertically set, the bottom of the baffle 632 is connected to the top of the support tube 5.

[0029] Preferably, the connector 631 further includes a bearing disc for frictionally engaging the connector 631 and for tightening or loosening the rotating device 63 to adjustably connect the baffle 632 to the rotating device 63.

[0030] The drainage installation component 2 of this application integrates the functions of drainage channel and strength support in a single component. The drainage channel is inclined, allowing rainwater to drain naturally by gravity, improving the drainage efficiency of the roof 1 structure. Furthermore, the drainage channel is radially distributed with the center of the roof 1 as a reference, enabling rapid rainwater drainage, preventing moisture leakage within the insulation layer, extending the building's service life, and reducing subsequent maintenance costs. Simultaneously, the support columns 3 are positioned between the intersecting drainage channels, providing stable vertical support for the overall structure of the roof 1, significantly improving the overall structural strength of the roof 1. Additionally, the inclined ramp 4 is equipped with a structure whose inclination angle matches that of the drainage channel. The hollow support pipe 5 provides drainage and ventilation channels for the roof 1 while improving the strength of the roof 1. At the same time, by setting several support frames 6 along the length of the inclined ramp 4, and the support frames 6 having a protrusion 61 with a height greater than the top of the support column 3 after installation, it provides effective support and positioning when a waterproof membrane needs to be laid after the support frames 6 are installed, preventing the slope accuracy from being affected by the gravity during subsequent construction, and ensuring the long-term reliable operation of the drainage of the roof 1. In addition, the support pipe 5 is hollow, which can have the function of venting while draining, and can orderly discharge the water vapor of the roof 1 structural layer through the pipe, avoiding the construction structure from being damp and expanding due to the retention of moisture.

[0031] Furthermore, the connector 631 of this application is detachably installed by inserting a protruding piece 65 into a positioning groove on the connecting rod 62. The protruding piece 65 allows the connector 631 to be quickly disassembled after being pushed away from the positioning groove. Simultaneously, the connector 631 can rotate relative to the connecting rod 62 via a rotating rod passing through a rotating device 63. This allows the baffle 632 to flexibly adjust its deflection angle according to the specific installation position of the support frame 6 within the inclined ramp 4. The bearing disc is used to frictionally engage the connector 631 to tighten or loosen the rotating device 63, achieving stepless adjustment and instant locking of the baffle 632 angle. The support frame 6 can be adjusted and repositioned according to actual needs during construction, ensuring construction accuracy and efficiency. The baffle 632 is detachably connected to the connector 631 and extends away from the protruding part 61 of the support frame 6, i.e. the support pipe 5. After the support frame 6 is installed, it abuts against the support pipe 5 in the inclined ramp 4, thereby limiting the relative position of the support pipe 5 and the support frame 6 before filling, preventing the support pipe 5 or the support frame 6 from shifting during the filling process, ensuring that the drainage channel will not change due to environmental influences, and has high construction accuracy and efficiency.

[0032] Meanwhile, this application incorporates a V-shaped groove 51 structure within the support pipe 5. The baffle 632 extends into the support pipe 5 through the V-shaped groove 51, forming a gas and liquid channel. Specifically, the support pipe 5 has a V-shaped groove at the location where the baffle 632 is installed. The baffle 632 extends into the support pipe 5 through the V-shaped groove and is welded to the V-shaped groove at both ends. This structure provides high support strength between the baffle 632 and the support pipe 5, preventing weakened waterproofing performance due to connection failure. Furthermore, the support pipe 5 structure can be configured to slope towards the center from both ends at its top. After the roof 1 is constructed... During rainwater leakage, the top of the support pipe 5 and the baffle 632 can guide the accumulated water, allowing most of the rainwater to enter the interior of the support pipe 5 and move along the support pipe 5 to drain the rainwater. At the same time, the baffle 632 extends into the interior of the support pipe 5, giving the baffle 632 and the support pipe 5 a high bonding strength. The V-shaped groove 51 structure of the support pipe 5 has a good effect on collecting rainwater and can effectively strengthen the cross-sectional strength of the support pipe 5, preventing the support pipe 5 from deforming when bearing the load of the roof 1 above, and further improving the structural reliability of the drainage channel.

[0033] Furthermore, in this application, the construction method uses the center of the long / wide side of the drainage installation component 2 as a reference to tilt and process it towards both ends of the corresponding side to form several inclined ramps 4, and forms support columns 3 at the intersection of the transverse and longitudinal ramps, ensuring the symmetry and uniform distribution of the drainage channels set in the drainage installation component 2. After the support frame 6 is set, the rotating device 63 is released by the bearing disc and the length and angle of the baffle 632 are adjusted based on the actual position of the support frame 6, so that the baffle 632 can contact the support pipe 5 after being set vertically, which can effectively improve the processing accuracy. After the baffle 632 is welded, the filling material is set in the inclined ramp 4 so that the filling height is at the same level as the support column 3, ensuring the flatness of the subsequent structure installation and greatly reducing the risk of leakage during subsequent use.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included within the protection scope of the present invention.
