Description

Technical Field

[0001] This application relates to the field of steel structure buildings, and in particular to a waterproof and seepage-proof structure for steel structure factory buildings and its construction process. Background Technology

[0002] Steel structure factory buildings primarily refer to buildings whose main load-bearing components are made of steel, including steel columns, steel beams, steel foundations, steel roof trusses (although factory buildings with large spans are now mostly constructed with steel roof trusses), and steel roofs. Steel structure factory buildings can also be divided into light-duty and heavy-duty steel structure factory buildings. Steel structure factory buildings have advantages such as lightweight construction, high strength, short construction period, reduced investment costs, easy relocation, and pollution-free recycling.

[0003] For steel structure factory buildings, water leakage can affect and even damage the equipment inside. Therefore, waterproofing is a crucial factor. Existing steel structure factory buildings typically use waterproof membranes at the joints of the steel roof panels. The membrane is adhered to both ends of the membrane to seal the gaps between the two steel roof panels, achieving a waterproofing effect. However, the waterproof membrane has a certain thickness, and after application, it forms protrusions on the steel roof, restricting rainwater from flowing down. During the rainy season, prolonged rainfall can prevent the accumulated rainwater from evaporating quickly, causing the waterproof membrane to detach and ultimately fail. Summary of the Invention

[0004] In order to reduce the accumulation of rainwater caused by protrusions in the waterproof membrane, this application provides a waterproof and seepage-proof structure for steel structure factory buildings.

[0005] The waterproof and seepage-proof structure for steel structure workshops provided in this application adopts the following technical solution:

[0006] A waterproof and seepage-proof steel structure factory building includes a factory building frame assembled from several steel columns and several steel beams. Several steel roofs are installed on the steel beams. The steel roofs are stacked at an incline towards the ground, with the steel roof at the higher position pressing down on the steel roof at the lower position. A waterproof membrane is installed between the two steel roofs.

[0007] By adopting the above technical solution, the waterproof membrane is placed between two steel roof panels. The stacking of the steel roof panels prevents the protruding parts of the waterproof membrane from blocking the path of rainwater falling from the roof, thus reducing the accumulation of rainwater caused by the protrusions of the waterproof membrane.

[0008] Optionally, one end of the waterproof membrane is adhered to the side of the steel roof located at the lower position facing the side of the steel roof located at the higher position, and the other end is bent and adhered to the side of the steel roof located at the higher position facing the side of the steel roof located at the lower position.

[0009] By adopting the above technical solution, the waterproof membrane can be bent to adhere to two steel roofs at the same time, which can fill the gaps between the steel roofs and improve the connection strength between the steel roofs.

[0010] Optionally, the factory building frame is equipped with wall panels around its perimeter, and one of the wall panels has a door frame.

[0011] By adopting the above technical solution, the wall panels are used to enclose the factory building, and the opening of the door frame facilitates the installation of the door panels.

[0012] Optionally, the steel roof at the lowest point extends beyond the wall panels.

[0013] By adopting the above technical solution, the steel roof extending beyond the wall panels can reduce the probability of rainwater dripping onto the wall panels when it falls along the steel roof.

[0014] Optionally, a baffle is provided between the steel roof and the wall at the lowest point, with the two ends of the baffle inserted into the steel roof and the wall respectively.

[0015] By adopting the above technical solution, the baffle can block the gaps between the steel roof and the wall, thereby reducing the probability of rainwater entering the factory through the gaps in the wall.

[0016] Optionally, an arc-shaped connector is provided between the wall panels, with both ends of the arc-shaped connector being inserted into the two connected wall panels respectively.

[0017] By adopting the above technical solution, the arc-shaped connector changes the gap between wall panels from a straight line to an arc, increasing the total length of the gap and reducing the probability of rainwater seeping through the gap.

[0018] Optionally, both the steel roof and wall panels are made of metal plates with embedded insulation layers.

[0019] By adopting the above technical solutions, the installation of the insulation layer can improve the insulation capacity of the factory building.

[0020] Optionally, the steel column is provided with a reinforcing part at the end facing the ground, and the reinforcing part is inserted into the ground.

[0021] By adopting the above technical solution, the reinforcement can improve the installation strength of the steel column on the ground.

[0022] A construction process for a waterproof and seepage-proof steel structure factory building includes the following steps:

[0023] S1: Insert steel columns. Based on the factory area, insert the reinforcing part of the steel columns into the ground to form a ring. Then fix the steel columns to the ground with expansion bolts.

[0024] S2: Install steel beams, overlap the steel beams onto the steel columns and fix them in place with bolts;

[0025] S3: Install wall panels. Install wall panels around the circumference of the ring formed by the steel columns and fix the wall panels to the steel columns with bolts.

[0026] S4: Insert arc-shaped connectors between adjacent wall panels;

[0027] S5: Install the waterproof membrane, attaching one end of the waterproof membrane to one side of the steel roof.

[0028] S6: Install the steel roof. Install the steel roof with the waterproof membrane on the steel beam. When installing the steel roof, tilt the side with the waterproof membrane towards the ground and bend the waterproof membrane so that the side of the waterproof membrane away from the steel roof adheres to the side of the other steel roof away from the ground.

[0029] S7: Install a baffle between the wall and the lowest point of the steel roof to block the gap between the wall and the steel roof.

[0030] By adopting the above technical solution, the application of waterproof membrane can not only fill the gaps between steel roofs, but also improve the connection strength between steel roofs.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. The waterproof membrane is placed between two steel roof panels. The stacking of the steel roof panels prevents the raised parts of the waterproof membrane from blocking the path of rainwater falling from the roof, thus reducing the accumulation of rainwater caused by the raised parts of the waterproof membrane.

[0033] 2. By bending the waterproof membrane, it can be adhered to two steel roof panels simultaneously, which fills the gaps between the steel roof panels and improves the connection strength between them.

[0034] 3. The steel roof extending beyond the wall panels reduces the probability of rainwater dripping onto the wall panels as it falls along the steel roof.

[0035] 4. The baffle can block the gaps between the steel roof and the walls, thereby reducing the probability of rainwater entering the factory through the gaps in the walls;

[0036] 5. The curved connector changes the gap between wall panels from a straight line to a curved line, increasing the total length of the gap and reducing the probability of rainwater seeping through the gap;

[0037] 6. The installation of an insulation layer can improve the insulation capacity of the factory building;

[0038] 7. The reinforcement can improve the installation strength of the steel column on the ground. Attached Figure Description

[0046] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0047] This application discloses a waterproof and seepage-proof structure for steel structure factory buildings, referring to... Figure 1 and Figure 2The factory building frame 1 consists of several steel columns 101 and several steel beams 102 assembled together. The steel columns 101 are arranged in a rectangular pattern on the ground. Each steel column 101 is a long, thin steel bar column with mounting holes 11 at one end along its length for installing expansion bolts. The selection of expansion bolts depends on the soil conditions of the site. Loose soil requires longer expansion bolts, while compacted soil allows for shorter bolts. The steel columns 101 are installed on the ground using expansion bolts. The steel beams 102 are evenly installed along the length of the factory building on the steel columns 101. On the side away from the ground, steel beam 102 is bolted to steel column 101. Connecting rods 2 are bolted between adjacent steel columns 101. Connecting rods 2 can increase the structural strength of the entire factory frame 1. Several crossbeams 3 are connected between adjacent steel beams 102. The crossbeams 3 are bolted to the adjacent steel beams 102. The crossbeams 3 are evenly distributed along the width of the factory frame 1. The crossbeams 3 can also increase the structural strength of the entire factory frame 1. Steel columns 101, steel beams 102, connecting rods 2 and crossbeams 3 are all made of stainless steel. Stainless steel has good corrosion resistance, high strength, and is easy to process and clean.

[0048] Reference Figure 2 and Figure 3 Several steel roof panels 4 are installed on the steel beam 102. Each steel roof panel 4 is a rectangular metal sheet. The steel roof panels 4 are stacked at an angle towards both sides of the factory building's width direction. The width of each steel roof panel 4 faces the width of the factory building frame 1, and its length faces the length of the factory building frame 1 and extends beyond both ends of the frame 1. The higher-positioned steel roof panel 4 rests on top of the lower-positioned steel roof panel 4. Each steel roof panel 4 has a countersunk hole 12 on its ground-facing side for installing bolts to fix it to the steel beam 102. The countersunk hole 12 does not penetrate the steel roof panel 4, preventing leakage. A waterproof membrane 5 is placed between two steel roof panels 4. The waterproof membrane 5 is stacked on top of the lower-positioned steel roof panel 4. The roof 4 is also stacked on top of the steel roof 4 located at a higher position. The waterproof membrane 5 is placed between the two steel roof 4. The stacking of the steel roof 4 prevents the protruding part of the waterproof membrane 5 from blocking the path of rainwater falling from the roof, thus reducing the accumulation of rainwater caused by the protrusion of the waterproof membrane 5. A cover plate 13 is set between the two highest steel roof 4 on both sides. The cover plate 13 covers the gap between the two steel roof plates. The waterproof membrane 5 is placed at both ends of the cover plate 13 and between the steel roof plates. When the steel end caps are stacked, the overlap area should not be less than 10 centimeters. The larger the overlap area, the better the waterproof effect. However, the overlap area should not be too large, otherwise too many steel end caps will be needed and the cost will be too high. Therefore, the overlap area should not exceed one-tenth of the steel end cap.

[0049] Reference Figure 2 and Figure 3One end of the waterproof membrane 5 is adhered to the side of the lower steel roof 4 facing the higher steel roof 4. The other end of the waterproof membrane 5 is bent and adhered to the side of the higher steel roof 4 facing the lower steel roof 4. By bending the waterproof membrane 5, it can be adhered to both steel roof 4 pieces simultaneously, filling the gap between the steel roof 4 pieces and improving the connection strength between them. The waterproof membrane 5 between the cover plate 13 and the steel roof 4 is adhered in the same way as the waterproof membrane 5 between the two steel roof plates. The lowest steel roof 4 extends out... Outside the wall panel 6, the steel roof 4 extends beyond the wall panel 6 to reduce the probability of rainwater dripping onto the wall panel 6 when it falls along the steel roof 4. The waterproof membrane 5 is preferably the same length as the steel structure factory building. If there is no waterproof membrane 5 of the same length as the steel structure factory building, it is necessary to form a waterproof membrane of the same length as the steel structure factory building by bonding the waterproof membrane 5. The width of the overlapping area of ​​the bonding joint of the waterproof membrane 5 should not be too small, as it should not be less than five centimeters. At the same time, the waterproof membrane 5 in the overlapping area needs to be thinned so that the thickness of the overlapping area of ​​the two waterproof membranes 5 is the same as that of a single waterproof membrane 5.

[0050] Reference Figure 4 and Figure 5 The factory building frame 1 is equipped with metal wall panels 6 all around its perimeter. One of the wall panels 6 has a door frame cut out by laser cutting, which is used to install the factory door. Arc-shaped connectors 8 made of metal plates are installed between the wall panels 6. The two ends of the arc-shaped connectors 8 are respectively inserted into the two connected walls. The part of the arc-shaped connectors 8 inserted into the wall panel 6 has at least one bend. The arc-shaped connectors 8 can make the circular horizontal gap between the wall panels 6 into an arc shape, thereby increasing the length of the gap and reducing the probability of rainwater leakage into the factory building.

[0051] Reference Figure 2 and Figure 6A baffle 7 is installed between the lowest steel roof 4 and the wall. The baffle 7 has inserts 14 at both ends, and slots 15 are provided on the steel roof 4 and the wall corresponding to the inserts 14. The inserts 14 at both ends of the baffle 7 are inserted into the slots 15 on the steel roof 4 and the wall, respectively, and the baffle 7 is fixed with bolts. The baffle 7 can block the gap between the steel roof 4 and the wall, thereby reducing the probability of rainwater entering the factory building through the wall gaps. The baffle 7 forms a cavity 16 between the steel roof 4 and the wall. The interior is filled with absorbent blocks 17. When there is heavy rain and strong winds, rainwater can still easily seep into the baffle 7. The absorbent blocks 17 can absorb the rainwater that seeps into the baffle 7 during heavy rain, further reducing the probability of water leakage in the factory. The absorbent blocks 17 are made of quicklime blocks. Quicklime blocks can absorb water and also generate heat after absorbing water. The heat generated by the quicklime blocks after absorbing water will be transferred to the wall panel 6, causing the temperature of the wall panel 6 to rise, thereby accelerating the evaporation of water in the gaps between the wall panels 6, and also achieving the effect of raising the temperature of the entire factory.

[0052] Reference Figure 1 and Figure 2 A reinforcing part 10 is provided at the end of the steel column 101 facing the ground. The reinforcing part 10 is inserted into the ground. The reinforcing part 10 is an inverted cone. The reinforcing part 10 is fixed to the steel column 101 by welding. The inverted cone can be easily inserted into the ground to reinforce the steel column 101. In order to save costs, the interior of the reinforcing part 10 can be made hollow.

[0053] Reference Figure 2Both the steel roof 4 and wall panels 6 are made of metal plates with an embedded insulation layer 9. The insulation layer 9 is made of insulating asbestos. The structure with the insulation layer 9 embedded inside the steel roof 4 and wall panels 6 can be produced by welding two thin metal plates and filling them with insulating asbestos before welding. For steel structure workshops, how to insulate is a necessary problem to solve. Embedding insulating asbestos inside the steel roof 4 and wall panels 6 can improve the insulation capacity of the workshop. At the same time, the embedded insulating asbestos can protect the insulating asbestos and reduce its rust. Since the steel roof 4 and wall panels 6 are exposed to wind and rain and are prone to rust, an anti-rust paint layer is applied to the surface of the steel roof 4 and wall panels 6 to protect them and reduce the probability of rust caused by wind and rain. The rust-preventive paint layer can be sprayed after the steel structure workshop is erected, focusing on areas directly exposed to rainwater. Alternatively, it can be sprayed entirely before the steel structure workshop is erected. Spraying after the steel structure workshop is erected saves paint, while spraying before the steel structure workshop is erected allows for convenient ground application. When spraying the entire steel roof 4 with the anti-rust paint layer on the ground, the area where the waterproof membrane 5 will be subsequently adhered can be covered to prevent the waterproof membrane 5 from adhering to the anti-rust paint layer. This ensures that when the anti-rust paint layer detaches from the steel roof 4, the waterproof membrane 5 will detach along with it. If the area where the waterproof membrane 5 will be adhered is unknown, the paint can be sprayed entirely on the area where the waterproof membrane 5 will be adhered, and then the anti-rust paint layer in that area can be scraped off.

[0054] A construction process for a waterproof and seepage-proof steel structure factory building includes the following steps: S1: Inserting steel columns 101. After compacting and leveling the open space, measure the appropriate factory building area on the open space and draw lines on the open space. Insert the reinforcing parts 10 of the steel columns 101 into the ground according to the factory building area. The steel columns 101 are evenly distributed along the measured lines to form a ring. Then, fix the steel columns 101 to the ground with expansion bolts. Then, install connecting rods between adjacent steel columns 101 with bolts; S2: Installing steel beams 102. The steel beams 102 are overlapped on the steel columns 101 and fixed with bolts. Then, fix the crossbeams 3 between the steel beams 102 with bolts to strengthen the structural strength of the steel beams 102; S3: Installing wall panels 6. Install wall panels 6 around the ring formed by the steel columns 101 and fix the wall panels 6 to the steel columns 101 with bolts. On column 101; S4: Insert arc-shaped connector 8 between adjacent wall panels 6; S5: Install waterproof membrane 5, attach one end of waterproof membrane 5 to one side of steel roof 4, and press waterproof membrane 5 tightly after attachment; S6: Install steel roof 4, install steel roof 4 with waterproof membrane 5 on steel beam 102. When installing steel roof 4, tilt the side with waterproof membrane 5 towards the ground and bend waterproof membrane 5 so that the side of waterproof membrane 5 away from steel roof 4 is attached to the side of another steel roof 4 away from the ground. The attachment of waterproof membrane 5 can fill the gap between steel roof 4 and improve the connection strength between steel roof 4; S7: Install baffle 7 between the wall and the lowest steel roof 4 to block the gap between the wall and steel roof 4.

[0055] The implementation principle of this application embodiment is as follows: Before construction, the wall panel 6 and steel roof 4 are cut into shape using a laser cutting machine, and a door frame is cut on one of the wall panels 6. Then, the required steel columns 101, connecting rods 2, steel beams 102, and crossbeams 3 are prepared. The open space where the factory building needs to be built is compacted by a ramming machine and then leveled by a road roller. The appropriate size of the factory building area is measured on the open space, and lines are drawn on the open space. According to the factory building area, the reinforcement part 10 of the steel column 101 is inserted into the ground along the drawn lines. The steel columns 101 are evenly distributed along the measured and drawn lines to form a ring. Then, the steel columns 101 are fixed to the ground with expansion bolts. Then, the reinforcement parts 10 of the steel columns 101 are added to the adjacent steel columns. Connecting rods are installed between steel beams 101 and steel columns 101 via bolts. The steel beams 102 are then connected and fixed to the steel columns 101 via bolts. Next, crossbeams 3 are fixed between the steel beams 102 via bolts to strengthen the structural strength of the steel beams 102. Wall panels 6 are installed circumferentially around the ring formed by the steel columns 101 and fixed to the steel columns 101 with bolts. The bolt holes for the wall panels 6 are countersunk holes 12. The countersunk holes 12 prevent through holes in the wall, reducing rainwater seepage. Arc-shaped connectors 8 are inserted between adjacent wall panels 6. The arc-shaped connectors 8 are inserted from above between the two wall panels 6. To facilitate the insertion of the arc-shaped connectors 8... Before installation, wall panel 6 needs to have pre-drilled holes compatible with the arc-shaped connector 8. One end of the waterproof membrane 5 is pasted onto one side of the steel roof 4. After pasting, the waterproof membrane 5 is pressed tightly. Then, the steel roof 4 with the waterproof membrane 5 installed is installed on the steel beam 102. When installing the steel roof 4, the side with the waterproof membrane 5 is tilted towards the ground, and the waterproof membrane 5 is bent so that the side of the waterproof membrane 5 away from the steel roof 4 adheres to the side of another steel roof 4 away from the ground. The application of the waterproof membrane 5 can fill the gaps between the steel roof 4s and also improve the connection strength between the steel roof 4s through its adhesive properties. A baffle 7 is installed between the lowest steel roof sections 4 to block the gap between the wall and the steel roof section 4. When installing the baffle 7, quicklime blocks are filled into the cavity 16 formed by the baffle 7, the wall, and the steel roof to complete the installation of the steel structure workshop. In this embodiment, the steel structure workshop is connected by bolts, which are easy to disassemble and can be reused. When it rains, the rainwater falls on the roof and then falls along the inclined steel roof section 4. During this process, the waterproof membrane 5 prevents the probability of rainwater seeping into the steel structure workshop from between the two steel roof sections 4. The baffle 7 and the arc-shaped connector 8 can also reduce the probability of rainwater seeping into the steel structure workshop.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
