[0001] The invention relates to the technical field of ridge waterproof construction building steel structure, in particular to a ridge waterproof construction building steel structure installation method. Background Art

[0002] The roof is the outer protective component of the top layer of the building. It is used to resist the influence of adverse factors such as rain, snow, wind, frost, solar radiation, temperature changes, etc. in nature, to ensure a good use environment inside the building. The roof should meet the functional requirements of being strong and durable, waterproof, heat-insulating, heat-insulating, fire-proof and resisting various adverse effects. The protruding parts of the steel structure roof have always been a headache for waterproofing. The waterproof materials on the market, such as silica gel and APP, cannot solve the leakage problem of the roof well. The use of steel structure roof waterproofing system can solve the above problems well, and this device is used for ridge waterproofing construction of building steel structure.

[0003] However, the existing ridge building structure usually adopts a combined structure of a connecting frame, and the roof waterproofing effect is not significant enough. It is okay for a short time, but after long-term use, the waterproofing effect will decrease and other structures will lose stability. In addition, some impurities are easily accumulated on the roof. If they are not discharged, the roof will cause corrosion, thereby gathering into larger impurities and causing drainage blockage on the roof. If this continues for a long time, it will cause quality problems of the device. In addition, the steel structure inside the device is usually installed with an overall fixed structure. The installation between the structures is not simple enough and the installation efficiency is low. Therefore, it does not meet the existing needs.

[0019] The present invention has the following beneficial effects:

[0020] 1. The steel structure of the roof waterproof construction building has a connection structure between a rolling slide and a supporting bearing. When rainwater falls on the upper surface of the rolling slide, downward pressure is generated and acts on the rolling slide. The rolling slide is in an oblique state, and the potential energy of the falling rainwater is converted into the kinetic energy of the rolling slide, thereby driving the rolling slide to rotate. At the same time, when the rolling slide rotates, the impurities that fall into it are discharged from the interior of the guide bevel through the sliding effect of the rolling slide. Through the cooperation of the rolling slide, the guide bevel and the anti-blocking layer, the anti-blocking layer collects rainwater and impurities over a large area, and then the guide bevel guides the water to the upper surface of the rolling slide, providing the rolling slide with rotational power and kinetic energy, and then the rolling slide provides support and drainage for the rainwater, and at the same time effectively discharges the impurities on the roof as a whole to avoid large impurities that are difficult to discharge, thereby realizing the function of discharging rainwater and other impurities, and this mechanism can adapt to a variety of drainage environments, providing the device with rainwater diversion and anti-blocking functions.

[0021] 2. The ridge waterproof construction building steel structure can provide a sealing connection effect between the two lower baffles through the action of the connecting sealing strip, and can increase the corresponding connection strength. At the same time, it is easy to install, which can greatly reduce the installation steps between the two, thereby reducing the overall installation time. The installation is simple and the connection operation can be completed without the use of tools. Through the bending of the vertical card edge and the vertical groove structure, the connecting sealing strip can effectively prevent rainwater from falling into the roof when connected to the outer side of the lower baffle, and the multiple tortuous connection structure can prevent rainwater from penetrating into the roof, further improving the sealing between the lower baffles, so that the lower baffles between the two have a very high waterproof effect.

[0022] 3. The ridge waterproof construction building steel structure greatly improves the assembly convenience of the ridge steel frame structure and reduces the overall installation time through the connection structure between the central beam and the ridge support frame. The assembly method is relatively simple and easy to operate, which greatly improves the installation steps of the device and reduces the assembly time and overall installation efficiency of the device. The characteristics of the device can extend the length of the central beam according to the site conditions, and then evenly install the ridge support frame on both sides of the central beam, so that the device has extremely high adaptability and is suitable for the installation and use of steel structures in various industries and environments.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1

[0032] See also Figure 1-6, and discloses a method for installing a steel structure for waterproofing a roof ridge, wherein the steel structure for waterproofing a roof ridge comprises a supporting base column 1 and a ridge support frame 2 on the supporting base column 1, a symmetrical crossbeam 3 is arranged at the lower end of the ridge support frame 2, a middle crossbeam 4 is installed at one end of the ridge support frame 2, and the middle crossbeam 4 is used to connect two ridge support frames 2, a lower baffle 16 is installed at the upper end of the ridge support frame 2, an anti-blocking layer 17 is installed at the upper end of the lower baffle 16, a middle shielding frame 18 is installed at the upper end of the anti-blocking layer 17, and one end of the anti-blocking layer 17 is installed There is a limited clamping edge 19, and an anti-blocking groove 22 is provided inside the anti-blocking layer 17. A guide bevel 23 located inside the anti-blocking groove 22 is symmetrically provided inside the anti-blocking layer 17. A rolling slide 24 is installed at the lower end of the guide bevel 23. A support bearing 34 is symmetrically installed inside the rolling slide 24. A connecting frame 36 is installed inside the support bearing 34. The connecting frame 36 is used to place the rolling slide 24 on the lower surface of the anti-blocking layer 17. A supporting top pile 14 is installed at the lower end of the anti-blocking layer 17. The supporting top pile 14 is used to fix the anti-blocking layer 17 on the lower baffle 16.

[0033] When in use, first install the two ridge support frames 2 symmetrically and fix them through the middle crossbeam 4, then place the lower baffle 16 symmetrically on the upper end of the ridge support frame 2, place the middle shielding frame 18 on the upper end of the two anti-blocking layers 17, and clamp it inside the limiting base 20 through the limiting clamping edge 19. When rainwater falls into the upper end of the anti-blocking layer 17, it will pour into the inside of the anti-blocking groove 22 through the concave structural characteristics of the anti-blocking groove 22, and will be guided and limited by the guiding bevel 23, and fall on the upper surface of the rolling slide 24. Through the connection structure between the rolling slide 24 and the support bearing 34, when rainwater falls on the upper surface of the rolling slide 24, it will generate downward pressure and act on the rolling slide 24, and the rolling slide 24 is in an oblique state. The potential energy of falling rainwater will be converted into kinetic energy of the rolling slide 24, thereby driving the rolling slide 24 to rotate. At the same time, as the rolling slide 24 rotates, the impurities that fall into it are discharged from the interior of the guide bevel 23 through the sliding effect of the rolling slide 24. Through the cooperation effect of the rolling slide 24, the guide bevel 23 and the anti-blocking layer 17, the water is collected over a large area by the anti-blocking layer 17, and then the guide bevel 23 guides the water to the upper surface of the rolling slide 24, providing the rolling slide 24 with rotational power kinetic energy, and then the rolling slide 24 provides support and drainage for the rainwater, and at the same time effectively discharges the impurities on the roof as a whole to avoid large impurities that are difficult to discharge, thereby realizing the function of discharging rainwater and other impurities.

[0034] Example 2

[0035] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-6 The outer side of the rolling carriage 24 is provided with an oblique side edge 32 .

[0036] The inclined side edge 32 is located at the lower end of the two guiding inclined edges 23. Through the action of the inclined side edge 32, when the guiding inclined edges 23 guide rainwater into the upper surface of the rolling slide 24, the inclined side edge 32 can limit the rainwater so that it slides along the track of the rolling slide 24, thereby achieving the effect of limiting and diverting the rainwater.

[0037] Example 3

[0038] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-6 An expansion gap 33 is provided inside the oblique side edge 32 .

[0039] The expansion gap 33 is arranged inside the oblique side 32. The expansion gap 33 is normally in a closed state. When the expansion gap 33 rotates to the two end positions of the rolling slide 24, it will form an open state. Through the action of the expansion gap 33, the oblique side 32 can be provided with a folding effect at the turning point, thereby avoiding the increase of resistance when the oblique side 32 is at the turning point, affecting the rotation effect of the rolling slide 24, thereby reducing the resistance of the oblique side 32 to rotate, and will not affect the diversion effect of rainwater.

[0040] Example 4

[0041] This embodiment is an improvement made on the basis of embodiment 3. For details, please refer to Figure 1-6 A bearing baffle 35 is provided at the upper end of the rolling slide 24 .

[0042] The bearing baffles 35 are arranged on the upper surface of the rolling slide 24, and rainwater and other impurities are discharged into the upper surface of the rolling slide 24 through the guiding bevel 23. After being discharged into the upper surface of the rolling slide 24, the rainwater and impurities will accumulate on the upper surface of the bearing baffles 35. Through the action of the bearing baffles 35, the amount of rainwater accumulation on the upper surface of the rolling slide 24 can be increased. The greater the amount of accumulation, the greater the weight. When heavy rainwater accumulates in the bearing baffles 35, the downward pressure force formed is also greater, which makes the downward sliding speed of the rolling slide 24 faster, thereby further increasing the rotation speed of the rolling slide 24 and improving the drainage efficiency of the rainwater and impurities of the rolling slide 24.

[0043] Example 5

[0045] During installation, the lower baffle 16 is first placed on the upper surface of the ridge support frame 2 , and the ridge support frame 2 is simultaneously inserted into the positioning groove 31 to form a fixed state, thereby further improving the installation efficiency of the lower baffle 16 .

[0046] Example 6

[0047] This embodiment is an improvement made on the basis of embodiment 5. For details, please refer to Figure 1-6 A vertical extension plate 38 is provided at the lower end of the reinforcing rib 37 , and a fixing lock buckle 15 is provided at the upper end of the ridge support frame 2 .

[0048] The anti-blocking layer 17 is placed on the upper end of the ridge support frame 2, and then the lower baffle 16 is pressed down so that the upper end of the ridge support frame 2 is embedded in the positioning groove 31. Then, the lower baffle 16 is slid obliquely downward along the trajectory of the upper surface of the ridge support frame 2, so that the vertical extension plate 38 is stuck on one side of the fixed lock buckle 15 to form a locked state, thereby improving the installation efficiency of the lower baffle 16. The structure is simple to operate and easy to use, which greatly reduces the installation steps of the ridge structure.

[0051] When installing the two lower baffles 16, first embed the side vertical groove 28 into the inside of the side groove 25, and at the same time, the bottom side 29 is clamped on the inner side of the bottom positioning groove 30, and the vertical clamping edge 26 will be inserted into the inside of the side vertical groove 28 to form a combined connection structure. Through the action of the connecting sealing strip 27, a sealing connection effect can be provided between the two lower baffles 16, and the corresponding connection strength can be increased. Through the bending of the vertical clamping edge 26 and the vertical groove structure, the connecting sealing strip 27 is effectively prevented from falling into the roof when connected to the outer side of the lower baffle 16. The multiple structures isolate them, so that the lower baffle 16 has an extremely high waterproof effect.

A first fixed plate frame 8 is installed on one side of the central crossbeam 4, and a second fixed plate frame 10 is installed on the other side of the central crossbeam 4. An extended fixed tube 9 is provided on the outer side of the first fixed plate frame 8, and a fixed hole groove 11 is provided inside the second fixed plate frame 10.
