Description

Technical Field

[0001] This utility model relates to the field of prefabricated buildings, specifically to a roof structure suitable for urban renewal. Background Technology

[0002] In towns, counties, and some urban streets in my country, there are a large number of old buildings along the streets. Due to years of disrepair, the exterior walls are incomplete, polluted, and damaged, and the buildings have a messy appearance. At the same time, due to a lack of management, some residents have built temporary facilities on their roofs at will. Because the shapes and materials are very different from the architectural style, the parts of the buildings look out of place with the surrounding environment, which affects the overall image of the towns and streets.

[0003] To enhance the overall aesthetics and quality of urban architecture, "urban renewal" is a crucial means of building modern cities, involving the redevelopment of buildings in specific areas or streets within a city to achieve a unified style. During roof design, due to the age of the buildings and concerns about the potential impact of new roofs on the building's load-bearing capacity, some designs simply abandon the addition of roofs. However, for commercial streets with specific requirements, such as creating an antique architectural style, abandoning roofs would significantly detract from the overall visual appeal of the building complex. Utility Model Content

[0004] The present invention aims to provide a roof structure suitable for urban renewal, so as to solve the problem of adding a roof to old buildings during the renovation process without putting a burden on the load-bearing capacity of the old buildings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a roof structure suitable for urban renewal, comprising a beam-column unit and a top surface unit detachably installed on the beam-column unit. The beam-column unit includes a triangular frame and a crossbeam, with the three ends of the triangular frame detachably connected to the crossbeam. The top surface unit includes a roof and a thermal insulation board located below the roof. An eaves board is detachably connected to the edge of the top surface unit. A rain guide groove is provided on the eaves board parallel to the crossbeam. The beam-column unit is also provided with supporting steel columns connected to the ground.

[0006] The principle and advantages of this scheme are as follows: In this scheme, the roof structure is separated from the original building and independently supported on the ground by supporting steel columns. Therefore, the roof structure in this scheme will not pose a load-bearing risk to the original old building. At the same time, this scheme can redesign new roof styles according to new functional and aesthetic needs, such as hip roof, gable roof, and palace roof in antique buildings, which greatly improves the overall aesthetics of the updated building complex.

[0007] In addition, all components in this solution are assembled using a detachable connection method, so there is no need to cut or weld materials on site. The construction process is simple, the assembly speed is fast, and the cycle is short. At the same time, there are no construction pollution problems such as high noise and large dust during the construction process.

[0008] Preferably, as an improvement, slotted connectors for mounting crossbeams can be detachably connected to the opposite surfaces of two adjacent tripods.

[0009] Preferably, as an improvement, a reinforcing beam is provided in the middle of the tripod body, and a triangular cavity is formed between the reinforcing beam and the tripod body, and a grid is provided inside the triangular cavity.

[0010] Preferably, as an improvement, each fascia board is provided with a snap-fit ​​groove for snapping the roof and thermal insulation board.

[0011] Preferably, as an improvement, a number of auxiliary support bars are connected between two adjacent tripod bodies. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of Embodiment 1.

[0013] Figure 2 This is a schematic diagram of the column base structure in Example 2.

[0014] Figure 3 This is a schematic diagram of the connection between the column base and the supporting steel column in Embodiment 2. Detailed Implementation

[0015] The following detailed description illustrates the specific implementation method:

[0016] The reference numerals in the accompanying drawings include: 1. Triangular frame; 2. Horizontal beam; 3. Channel connector; 4. Reinforcing beam; 5. Roof; 6. Thermal insulation board; 7. Eaves board; 8. Supporting steel column; 9. Base plate; 10. Connecting steel part; 11. Connecting plate; 12. Connector.

[0017] The basic implementation examples are as follows: Figure 1As shown: A roof structure suitable for urban renewal. Based on the actual structure of the old building, the roof structure can be designed as a single-span, double-span, triple-span, or multi-span structure. This scheme takes a four-span roof structure as an example, including interconnected top surface units and beam-column units. The beam-column unit includes four triangular frames 1 and multiple crossbeams 2. The three ends of the triangular frames 1 are detachably connected to the crossbeams 2. Specifically, several auxiliary support bars are connected between two adjacent triangular frames 1, and grooved connectors 3 are bolted to the opposite surfaces of two adjacent triangular frames 1. The grooved connectors 3 can be "]" shaped or a rectangular structure with one side open. The crossbeams 2 are square steel pipes, and the two ends of the crossbeams 2 are respectively fitted onto the grooved connectors 3 of the left and right triangular frames 1 and fixed by high-strength bolts.

[0018] In addition, a reinforcing beam 4 is horizontally installed in the middle of the tripod 1, forming a triangular cavity with the tripod 1, and a grid is installed inside the triangular cavity. This arrangement not only further enhances the stability of the tripod 1, but also enhances the decorative appearance of the roof.

[0019] The top unit has a triangular cross-section and includes a roof 5 and an insulation board 6 located below the roof 5. The insulation board 6 is a conventional integrated insulation board, which already provides insulation for the building. Each edge of the top unit is detachably connected to a fascia board 7. Specifically, each fascia board 7 has a snap-fit ​​groove, into which the edges of the roof 5 and the insulation board 6 are snapped and fixed with bolts. A rain guide is fixed to the outer side of the fascia board 7, parallel to the crossbeam 2. One end of the rain guide is connected to the ground drainage system via a pipe. The top edge of the rain guide is lower than the upper surface of the fascia board 7, allowing rainwater from the roof 5 to flow smoothly into the rain guide and into the ground drainage system during heavy rain, thus preventing damage or water accumulation on the ground due to the impact of water from the roof.

[0020] The beam-column unit is also equipped with supporting steel columns 8 connected to the ground. Specifically, supporting steel columns 8 are vertically installed at the bottom of each triangular frame 1. The lower end of the supporting steel column 8 is fixed to the ground, so that the roof structure in this scheme is separated from the original building and is independently supported on the ground, thus avoiding any load-bearing risk to the original building.

[0021] Example 2

[0022] In this embodiment, as Figure 2 , Figure 3As shown, the lower end of the supporting steel column 8 is detachably connected to the column base. The column base includes a base plate 9, and a connecting steel member 10 is installed at each of the four corners of the lower surface of the base plate 9. The connecting steel member 10 can be a reinforcing bar. The upper surface of the base plate 9 is bolted to a mounting base. The mounting base includes a connecting plate 11 bolted to the base plate 9 and a connecting body 12 fixedly installed on the connecting plate 11. The connecting body 12 includes a square structure formed by connecting four steel plates.

[0023] The mounting base, base plate 9 and connecting steel parts 10 are connected as one unit. Then, pile holes are drilled on the ground at the locations corresponding to the four connecting steel parts 10. Concrete is then poured into the pile holes, and the connecting steel parts 10 on the base plate 9 are inserted into the concrete in the pile holes. After the concrete reaches the design strength, the steel column is fitted onto the outside of the connecting body 12 and the two are connected and fixed with bolts.
