Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to an irregularly shaped eaves structure for the roof of a prefabricated building. Background Technology

[0002] With the development of the construction industry, prefabricated buildings have gradually become the mainstream trend due to their advantages such as high efficiency and environmental protection. As an important part of the building roof, the eaves not only undertake functions such as drainage and sun shading, but also play a key role in the aesthetics of the building. However, the traditional eaves structure has many problems in prefabricated buildings.

[0003] Traditional cast-in-place eaves require on-site formwork, steel bar binding, and concrete pouring. The overall process is complex, highly susceptible to weather conditions, and has a long construction period. In particular, irregularly shaped eaves require customized molds during on-site fabrication. Traditional steel or wooden molds are difficult to form accurately, resulting in low overall reusability and increased production costs. Furthermore, some prefabricated eaves use simple bolt connections, which are prone to loosening during long-term use. Utility Model Content

[0004] The purpose of this utility model is to provide a non-standard eaves structure for prefabricated building roofs, in order to solve the problem mentioned in the background art that non-standard eaves require customized molds during on-site production. At this time, traditional steel molds or wooden molds are difficult to form accurately, resulting in low overall reusability, increased production costs, and some prefabricated eaves use simple bolt connections, which are prone to loosening during long-term use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-circular eaves structure for prefabricated building roofs, including a main eaves support, which is the main structure of the eaves of the prefabricated building roof. One end of the main eaves support is tightly fitted with a reinforcing frame, and the reinforcing frame is fixedly connected to the building surface by expansion bolts. A sloping roof is fixedly installed on the upper end of the main eaves support. The sloping roof, together with the main eaves support, constitutes the main structure of the non-circular eaves of the prefabricated building roof.

[0006] The bottom of the main eaves support has a strip-shaped protrusion, and the strip-shaped protrusion of the main eaves support is vertically penetrated by the second connecting beam. The surface of the second connecting beam is fitted with a limiting frame, and the limiting frame abuts against the surface of the main eaves support. The top of the second connecting beam is fixed to the surface of the sloping roof, and the surface of the sloping roof is also fixed with a first connecting beam. The first connecting beam penetrates the main eaves support and the reinforcing frame, and the main eaves support and the reinforcing frame are fitted together to form a T-shaped structure.

[0007] The upper surface of the main eaves support is provided with a reinforcing frame, which is snapped into the sloping roof. The reinforcing frame is penetrated by a positioning bolt, which penetrates both the main eaves support and the sloping roof. The bottom of the sloping roof has a fitting frame, which penetrates the main eaves support, and the bottom of the fitting frame is mortised and tenoned to one end of a non-circular eaves piece.

[0008] By adopting the above technical solution, the T-shaped interlocking structure and multi-directional connecting beams enhance the connection strength between the eaves and the main building, resisting wind loads and seismic forces.

[0009] Reinforcing frames and positioning bolts enhance the integrity of the sloping roof and the main support structure, reducing the risk of deformation.

[0010] Preferably, the connecting beam has an axial opening, and the axial opening of the connecting beam is threaded with a bolt.

[0011] By adopting the above technical solution, the axial opening of the connecting beam and the bolt design allow for on-site fine-tuning of the tightness, adapting to different installation errors and improving construction flexibility.

[0012] Preferably, the sloping roof has an extension frame on one side of the top of the slope, and the extension frame has a hole through which a bolt passes.

[0013] By adopting the above technical solution, the bolt hole design of the extension frame facilitates connection with other building components and enhances structural expandability.

[0014] Preferably, the outer wall of the sloping roof is fixed with a waterproof layer by an adhesive, and the outer wall of the sloping roof is provided with triangular protrusions at equal intervals.

[0015] By adopting the above technical solution, the combination of the waterproof layer and the triangular protrusions increases the adhesion and prevents rainwater penetration; the protruding structure can also disperse stress and extend the service life of the waterproof layer.

[0016] Preferably, the upper surface of the irregular eaves piece has a concave-convex structure that connects with the tenon and mortise of the fitting frame, and the side wall of the irregular eaves piece has a protrusion that is embedded in the drainage groove.

[0017] By adopting the above technical solution, the combination of the irregular eaves fitting and the drainage channel forms a flow channel, which effectively guides rainwater away from the main structure and reduces the risk of leakage.

[0018] Preferably, the drainage channel is formed on the surface of the strip-shaped protrusion at the bottom of the eaves main support, and the drainage channel is composed of a strip-shaped opening and a drainage hole that penetrates the drainage channel.

[0019] By adopting the above technical solution, the strip-shaped opening of the drainage channel and the design of the drainage hole ensure that rainwater is discharged quickly and avoids water accumulation from eroding the eaves structure.

[0020] Preferably, the reinforcing frame is perpendicular to the surface of the eaves main support, and the surface of the eaves main support is flush with the port of the positioning bolt, and the top of the positioning bolt is embedded in the waterproof layer.

[0021] By adopting the above technical solution, the top of the positioning bolt is embedded with a waterproof layer and the end is flush with it, which prevents the bolt from rusting, enhances the sealing of the joint, and extends the service life of the structure.

[0022] Compared with the prior art, the beneficial effects of this utility model are: the prefabricated building roof uses an irregularly shaped eaves structure:

[0023] 1. This eaves structure forms a T-shaped basic structure by interlocking the main eaves support and the reinforcing frame, and is fixed to the building surface by expansion bolts. The connecting beam runs through the two and is fastened with bolts, which effectively disperses the force and improves the wind load resistance and seismic performance. As the connecting beam runs vertically through the strip-shaped protrusion at the bottom of the main eaves support, and the limiting frame abuts against the support surface, it restricts displacement and further enhances the structural rigidity, avoiding deformation or loosening caused by external forces. In addition, the reinforcing frame is clamped in the sloping roof, and the positioning bolt runs through the three, so that the main eaves support and the sloping roof form an integrated structure, which improves the overall stability of the irregular eaves.

[0024] 2. The waterproof layer on the outer wall of the sloping roof is fixed with adhesive. The equidistantly distributed triangular protrusions increase the adhesion and prevent the waterproof layer from falling off. The mortise and tenon connection between the irregular eaves fitting and the frame and the matching of the drainage groove form a flow channel to guide rainwater out through the drainage holes and avoid water seepage. The top of the positioning bolt is embedded in the waterproof layer and the end is flush with the surface of the bracket to reduce the risk of rainwater seeping into the gaps and fully ensure the waterproof effect.

[0025] 3. Furthermore, the mortise and tenon connection between the irregularly shaped eaves piece and the fitting frame facilitates disassembly and replacement. If there is local damage, it can be repaired separately, reducing maintenance costs. The irregular shape of the irregularly shaped eaves piece is precisely processed directly in the factory, which effectively reduces the difficulties in on-site construction and ensures the accuracy and consistency of the irregular shape. The open design of the drainage channel connected to the irregularly shaped eaves piece facilitates the cleaning of debris and keeps the drainage unobstructed. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-6 This utility model provides a technical solution: a special-shaped eaves structure for prefabricated building roofs, including an eaves main support 1, a reinforcing frame 2, a connecting beam 1 3, a sloping roof 4, an extension frame 5, a waterproof layer 6, a connecting beam 2 7, a limiting frame 8, a fitting frame 9, a special-shaped eaves piece 10, a drainage channel 11, a reinforcing frame 12, and a positioning bolt 13.

[0035] Among them, the main support frame 1 of the eaves is the main structure of the eaves of the prefabricated building roof. One end of the main support frame 1 of the eaves is tightly fitted with the reinforcing frame 2, and the reinforcing frame 2 is fixedly connected to the building surface by expansion bolts. The upper end of the main support frame 1 of the eaves is fixedly installed with the sloping roof 4. The sloping roof 4 and the main support frame 1 of the eaves together form the main structure of the irregular eaves of the prefabricated building roof.

[0036] The bottom of the main eaves support 1 has a strip-shaped protrusion, and the strip-shaped protrusion of the main eaves support 1 is vertically penetrated by the second connecting beam 7. The surface of the second connecting beam 7 is fitted with a limiting frame 8, and the limiting frame 8 abuts against the surface of the main eaves support 1. The top of the second connecting beam 7 is fixed to the surface of the sloping roof 4, and the surface of the sloping roof 4 is also fixed with a first connecting beam 3. The first connecting beam 3 penetrates the main eaves support 1 and the reinforcing frame 2, and the main eaves support 1 and the reinforcing frame 2 are fitted together to form a T-shaped structure. The first connecting beam 3 has an axial opening, and the axial opening of the first connecting beam 3 is threaded with a bolt. The top of the sloping roof 4 has an extension frame 5, and the extension frame 5 has a hole through which a bolt passes. The outer wall of the sloping roof 4 is fixed with a waterproof layer 6 by an adhesive, and the outer wall of the sloping roof 4 is equidistantly provided with triangular protrusions.

[0037] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, before on-site installation, prefabricate components such as the eaves main support 1, reinforcing frame 2, sloping roof 4, connecting beam 1 3, connecting beam 2 7, limiting frame 8, fitting frame 9, irregular eaves piece 10, and reinforcement frame 12 in the factory. According to the hole position of the reinforcing frame 2, the drilling equipment drills holes at the marked positions. The drilling depth and diameter should meet the installation requirements of the expansion bolts. Place the reinforcing frame 2 in the predetermined position, pass the expansion bolts through the installation holes of the reinforcing frame 2 and insert them into the drilled holes. Tighten the expansion bolts with a wrench to make the reinforcing frame 2 firmly fixed to the building surface. Fit one end of the eaves main support 1 with the reinforcing frame 2 to form a T-shaped structure, ensuring a tight fit without obvious gaps. Then, stack the upper end of the eaves main support 1 with the sloping roof 4 to form an upper and lower stacked structure.

[0038] At this time, connecting beam 2 7 is placed on the upper end of the eaves main support 1 along with the sloping roof 4, thus vertically penetrating the strip-shaped protrusion at the bottom of the eaves main support 1. By fitting a limiting frame 8 on the surface of connecting beam 2 7 and adjusting the limiting frame 8 to abut against the surface of the eaves main support 1, and simultaneously installing connecting beam 1 3 through the eaves main support 1 and the reinforcing frame 2, as shown... Figures 1-4 As shown, bolts are screwed into the axial opening of connecting beam 3 and tightened to enhance the stability of the connection. At the same time, the top of connecting beam 7 is welded to the surface of the sloping roof 4. At this time, the sloping roof 4 and the eaves main support 1 are closely connected and together form the main structure of the irregular eaves.

[0039] Because the reinforcing frame 12 on the upper end of the main eaves support 1 is engaged and connected in the sloping roof 4, and the positioning bolt 13 penetrates the reinforcing frame 12, the main eaves support 1 and the sloping roof 4, the three are firmly connected together, which enhances the integrity and stability of the entire irregular eaves structure and improves its ability to resist external deformation.

[0040] A reinforcing frame 12 is provided on the upper surface of the main eaves support 1, and the reinforcing frame 12 is snapped into the sloping roof 4. The reinforcing frame 12 is penetrated by a positioning bolt 13, and the positioning bolt 13 penetrates the main eaves support 1 and the sloping roof 4. There is a fitting frame 9 at the bottom of the sloping surface of the sloping roof 4, and the fitting frame 9 penetrates the main eaves support 1. The bottom end of the fitting frame 9 is mortised and tenoned to one end of a special-shaped eaves piece 10. The upper surface of the special-shaped eaves piece 10 has a concave-convex structure that is mortised and tenoned with the fitting frame 9. The side wall of the special-shaped eaves piece 10 has a protrusion that is embedded in the drainage groove 11. The drainage groove 11 is opened on the surface of the strip-shaped protrusion at the bottom of the main eaves support 1, and the drainage groove 11 is composed of a strip-shaped opening and a drainage hole that penetrates the drainage groove 11. The reinforcing frame 12 is perpendicular to the surface of the main eaves support 1, and the surface of the main eaves support 1 is flush with the end of the positioning bolt 13. The top of the positioning bolt 13 is embedded in the waterproof layer 6.

[0041] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, the reinforcing frame 12 is snapped into the predetermined slot position in the sloping roof 4. Then, drilling equipment is used to drill holes at corresponding positions on the reinforcing frame 12, the eaves main support 1, and the sloping roof 4. Then, the positioning bolt 13 is inserted into the drilled hole and tightened to make the three securely connected. Note that the top of the positioning bolt 13 should be embedded into the waterproof layer 6 to a suitable depth. Since the surface of the eaves main support 1 is flush with the end of the positioning bolt 13, the reinforcement effect is guaranteed.

[0042] Apply adhesive evenly to the outer wall of the sloping roof 4. Then, lay the waterproof layer 6 on the adhesive-coated outer wall of the sloping roof 4. Use the equidistant triangular protrusions on the outer wall of the sloping roof 4 to ensure that the waterproof layer 6 is tightly attached to the sloping roof 4. Press it firmly with a tool to remove air. Afterward, select the corresponding irregular eaves piece 10 according to the architectural design requirements. Check whether the concave and convex structure of the upper surface of the irregular eaves piece 10 matches the mortise and tenon connection with the fitting frame 9. Since the fitting frame 9 passes through the main eaves support 1, one end of the irregular eaves piece 10 is connected to the bottom end of the fitting frame 9 through the mortise and tenon structure, which further strengthens the connection between the main eaves support 1 and the sloping roof 4. At the same time, the side wall of the irregular eaves piece 10 is embedded in the drainage groove 11. Through the cooperation of the drainage holes in the drainage groove 11, a corrosion-resistant and hydrophobic coating is sprayed on the surface of the drainage groove 11 to guide rainwater to flow in an orderly manner, ensure smooth drainage, and maintain the waterproof performance of the eaves structure.

[0043] Working principle: When using this prefabricated building roof irregular eaves structure, one end of the eaves main support 1 is tightly fitted with the reinforcing frame 2 to form a T-shaped structure. The reinforcing frame 2 is fixedly connected to the building surface by expansion bolts, providing stable foundation support for the eaves structure. The sloping roof 4 is fixedly installed on the upper end of the eaves main support 1. The connecting beam 1 3 passes through the eaves main support 1 and the reinforcing frame 2, and the connection is strengthened by the threaded bolts in the axial opening of the connecting beam 1 3. The connecting beam 2 7 vertically passes through the strip-shaped protrusion at the bottom of the eaves main support 1, and its top end is fixed to the surface of the sloping roof 4. At the same time, the limiting frame 8 fitted on the surface of the connecting beam 2 7 abuts against the surface of the eaves main support 1, further restricting the displacement of the connecting beam 2 7, ensuring that the sloping roof 4 and the eaves main support 1 are tightly connected, together forming the main structure of the irregular eaves.

[0044] The reinforcing frame 12 on the upper end of the main eaves support 1 is engaged and connected to the sloping roof 4. The positioning bolt 13 passes through the reinforcing frame 12, the main eaves support 1, and the sloping roof 4, firmly connecting the three together, enhancing the integrity and stability of the entire irregular eaves structure, and improving its ability to resist external deformation. The top of the positioning bolt 13 is embedded in the waterproof layer 6. The waterproof layer 6 is fixed to the outer wall of the sloping roof 4 with adhesive. The triangular protrusions equidistantly arranged on the outer wall of the sloping roof 4 increase the contact area between the waterproof layer 6 and the sloping roof 4, improve the adhesion of the waterproof layer 6, and effectively prevent rainwater penetration.

[0045] The fitting frame 9 at the bottom of the sloping roof 4 passes through the main eaves support 1. The bottom of the fitting frame 9 is connected to one end of the irregular eaves piece 10 by a mortise and tenon structure. This connection method is easy to install and has a certain structural stability, which allows the irregular eaves piece 10 to be firmly installed on the eaves structure, realizing the irregular design effect of the building appearance. The irregular eaves piece 10 can be replaced according to the building needs. The side wall of the irregular eaves piece 10 is embedded in the drainage groove 11. It cooperates with the drainage groove 11 to guide rainwater to flow in an orderly manner, ensure smooth drainage, maintain the waterproof performance of the eaves structure, and increase the overall practicality.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
