Description

Technical Field

[0001] This utility model specifically relates to a combined raised platform frame for building roof renovation. Background Technology

[0002] Roof load refers to the load borne on the roof surface and is a crucial factor that must be considered in building structural design and construction. The accuracy of roof load testing is primarily important for ensuring building safety. Roof load testing can promptly identify potential safety hazards, such as aging or damage to roof materials, thereby preventing accidents like roof collapses. For buildings such as industrial plants, regular load-bearing capacity testing can assess the current condition of the roof structure and allow for effective repair or reinforcement measures to ensure production safety. Furthermore, it must meet usage requirements, as different buildings have different roof load requirements. For example, commercial buildings may need to install large equipment or host events, necessitating sufficient roof load-bearing capacity. Load testing ensures that the roof meets these usage requirements.

[0003] When rooftop greening, water tanks, photovoltaic systems, and other post-construction components are added, the usage requirements of the roof change, involving changes in load. The roof load of these post-construction components often exceeds the original design requirements. For example, a series of preparatory work is required before carrying out rooftop greening construction. First, the roof structure needs to be assessed and reinforced to ensure it can withstand the weight of the green layer and continuous moisture. Second, a rooftop greening system suitable for the building's characteristics, climate conditions, and plant selection needs to be chosen. Finally, the necessary construction tools and materials need to be prepared, including waterproofing layers, protective layers, drainage boards, soil, and plants. Meanwhile, the construction of landscape gardens or green plant arrangements on the roof of a building requires the corresponding laying of a soil cover layer. The thickness of the soil cover layer varies from approximately 150mm to 2m. The soil cover layer must be compacted. After implementation, uneven stacking due to shape requirements or excessive thickness of the soil cover layer will cause a large load on the original roof slab. These additional components have large loads and occupy a large area. Solid laying is difficult to compress. The lack of standardized and unified treatment methods makes it difficult to advance or even impossible to renovate the project. Even if the renovation is successful, there are still significant safety hazards. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a combined raised platform for building roof renovation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A combined raised platform for building roof renovation includes multiple edge columns, multiple central columns, multiple first occupant connecting sleeves, multiple second occupant connecting sleeves, and multiple support plates. The edge columns and central columns are vertically arranged side by side on the roof. The lower end of each edge column is detachably connected to the edge of the roof, and the lower end of each central column is detachably connected to the roof. Multiple support plates are laid on the edge columns and central columns. Each support plate is detachably connected to the upper end of the edge column through at least one first occupant connecting sleeve, and each support plate is detachably connected to the upper end of the central column through at least one second occupant connecting sleeve. The multiple support plates are sequentially abutted to form a building surface reference plate.

[0007] As a preferred embodiment: each edge post includes a narrow base and a first steel pipe. The narrow base includes a small base plate, a cross-shaped connecting steel plate, and a top block. The top surface of the top block has a slot machined along its thickness direction. The first steel pipe is vertically positioned directly above the top block, with its lower end inserted into the slot. The upper end of the first steel pipe has multiple first strip-shaped notches machined, which are evenly arranged along the circumference of the first steel pipe. The length direction of the first strip-shaped notches is in the same direction as the height direction of the first steel pipe. A cross-shaped connecting steel plate is vertically positioned at the bottom of the top block, with its bottom end fixedly connected to the small base plate. The small base plate is detachably connected to the edge of the roof, and the transverse cross-sectional area of ​​the small base plate is smaller than that of the top block.

[0008] As a preferred embodiment: each centrally located small column includes a large base plate and a second steel pipe. The large base plate is detachably connected to the roof. The lower end of the second steel pipe is fixedly connected to the large base plate. The upper end of the second steel pipe is processed with multiple second strip-shaped notches. The multiple second strip-shaped notches are evenly arranged along the circumference of the second steel pipe. The length direction of the second strip-shaped notches is in the same direction as the height direction of the second steel pipe. The outer diameter of the second steel pipe is equal to the outer diameter of the first steel pipe.

[0009] As a preferred embodiment: the first spacer connecting sleeve and the second spacer connecting sleeve have the same structure. The first spacer connecting sleeve includes a first circular pad and a first inner support core strip. The first circular pad has a central hole processed along its thickness direction. The first inner support core strip is fixedly connected in the central hole. When the first spacer connecting sleeve is fitted onto the edge small column and the number of the first strip notches is four, the first inner support core strip is a cross-shaped strip. The four ends of the first inner support core strip are respectively located in the four first strip notches. The inner wall of the central hole is attached to the outer wall of the first steel pipe.

[0010] As a preferred option, the thickness of the first circular pad is in the range of 30~50mm.

[0011] As a preferred embodiment: the support plate is machined with multiple connecting holes along its thickness direction, the diameter of the connecting holes is set to match the outer diameter of the first steel pipe, and the diameter of the connecting holes is smaller than the outer diameter of the first circular pad.

[0012] As a preferred option, multiple reinforcing ribs are evenly arranged on the bottom surface of the support plate, and the top side of each reinforcing rib is fixedly connected to the support plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model utilizes multiple edge columns, multiple central columns, multiple first-position connecting sleeves, multiple second-position connecting sleeves, and multiple support plates to form a combined raised platform suitable for roof renovation. It can be used as a structural component in roof renovation projects to occupy space at the bottom and reduce load. Depending on specific structural design requirements, the multiple support plates, along with the edge columns and central columns, can form combined raised platforms of different shapes and heights, avoiding excessive or uneven roof loads that could lead to compressive imbalance. This also prevents hidden structural safety hazards in renovation projects, improves the uniformity of roof load-bearing, enhances the versatility of the raised platform, reduces the difficulty of modifying subsequent roof components, and facilitates standardized renovation methods, making it particularly suitable for complex renovation projects.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Specific implementation method one: Combining Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13This embodiment describes a combined roof-raising frame for building renovation, comprising multiple edge columns 1, multiple central columns 2, multiple first occupant connecting sleeves 3, multiple second occupant connecting sleeves 4, and multiple support plates 5. The edge columns 1 and central columns 2 are vertically arranged side-by-side on the roof 10. The lower end of each edge column 1 is detachably connected to the edge of the roof 10, and the lower end of each central column 2 is detachably connected to the roof 10. Multiple support plates 5 are laid on the edge columns 1 and central columns 2. Each support plate 5 is detachably connected to the upper end of the edge column 1 through at least one first occupant connecting sleeve 3, and each support plate 5 is detachably connected to the upper end of the central column 2 through at least one second occupant connecting sleeve 4. The multiple support plates 5 are sequentially abutted to form a building surface reference plate 6.

[0031] The upper end of the edge column 1 is machined with multiple first strip-shaped notches 7. The first strip-shaped notches 7 can be machined to a specified depth according to design requirements. The first occupier connecting sleeve 3 is fitted onto the edge column 1 through the first strip-shaped notches 7 to prevent the support plate 5 from slipping off when fitted onto the edge column 1. At the same time, the first occupier connecting sleeve 3 can also provide support and reduce the load after modification. The upper end of the central column 2 is machined with multiple second strip-shaped notches 8. The second strip-shaped notches 8 can also be machined to a specified depth according to design requirements. The support plate 5 is connected to the central column 2 through the second occupier connecting sleeve 4. The working principle of the second occupier connecting sleeve 4 is the same as that of the first occupier connecting sleeve 3.

[0032] Furthermore, when the depth of the multiple first strip-shaped notches 7 on the two adjacent first group edge columns 1 is less than the depth of the multiple first strip-shaped notches 7 on the two adjacent second group edge columns 1, the support plate 5 is fitted onto the edge column 1 in an inclined posture, avoiding the situation where the subsequent soil layer is piled up too thickly for the purpose of shaping, thereby avoiding damage to the load uniformity of the roof 10 and improving the uniformity and lightweight of the subsequent structure during the renovation process.

[0033] Specific Implementation Method Two: This implementation method is a further limitation of Specific Implementation Method One. The edge small column 1 has a reasonable structural form and can be stably installed at the edge of the roof 10. It is suitable for the narrow connection part at the edge of the roof 10 and can achieve a stable connection process. The specific structure of each edge small column 1 includes a narrow base 1-1 and a first steel pipe 1-2. The narrow base 1-1 includes a small base plate 1-1-1, a cross-shaped connecting steel plate 1-1-2, and a top block 1-1-3. The top surface of the top block 1-1-3 has a slot 1-1-4 processed along its thickness direction. The first steel pipe 1-2 is vertically set directly above the top block 1-1-3. The lower end of 1-2 is inserted into the slot 1-1-4. The upper end of the first steel pipe 1-2 is processed with multiple first strip-shaped notches 7. The multiple first strip-shaped notches 7 are evenly arranged along the circumference of the first steel pipe 1-2. The length direction of the first strip-shaped notches 7 is in the same direction as the height direction of the first steel pipe 1-2. A cross-shaped connecting steel plate 1-1-2 is vertically installed at the bottom of the top block 1-1-3. The bottom end of the cross-shaped connecting steel plate 1-1-2 is fixedly connected to the small base plate 1-1-1. The small base plate 1-1-1 is detachably connected to the edge of the roof 10 by multiple rivets. The transverse cross-sectional area of ​​the small base plate 1-1-1 is smaller than the transverse cross-sectional area of ​​the top block 1-1-3.

[0034] In this embodiment, one connection method between the top block 1-1-3 and the first steel pipe 1-2 is as follows: after the top block 1-1-3 is inserted into the slot 1-1-4, multiple connecting nails are inserted through the outer wall of the top block 1-1-3 into the first steel pipe 1-2, thereby further strengthening the connection between the top block 1-1-3 and the first steel pipe 1-2. Another connection method between the top block 1-1-3 and the first steel pipe 1-2 can also be a prefabricated and fixed connection from the factory.

[0035] In this embodiment, the first steel pipe 1-2 is a hollow steel pipe, which can reduce the pressure area of ​​the roof 10. Multiple round holes are machined on the small base plate 1-1-1, and construction personnel can install it on the roof 10 by matching the bolts with the round holes, which is convenient for installation and disassembly. The first strip notch 7 can be machined to a specified depth according to the design requirements. When the depths of the multiple first strip notches 7 on each first steel pipe 1-2 are not consistent, the support plate 5 can be fitted onto the first steel pipe 1-2 to form a base surface shape corresponding to different convex and concave shapes. The cross-shaped connecting steel plate 1-1-2 is wide at the top and narrow at the bottom to ensure that it can be installed on the small base plate 1-1-1.

[0036] Specific Implementation Method 3: This implementation method is a further limitation of Specific Implementation Method 1 or 2. Each central small column 2 includes a large base plate 2-1 and a second steel pipe 2-2. The large base plate 2-1 is detachably connected to the roof 10 by multiple rivets. The lower end of the second steel pipe 2-2 is fixedly connected to the large base plate 2-1. The upper end of the second steel pipe 2-2 is processed with multiple second strip-shaped notches 8. The multiple second strip-shaped notches 8 are evenly arranged along the circumference of the second steel pipe 2-2. The length direction of the second strip-shaped notches 8 is in the same direction as the height direction of the second steel pipe 2-2. The outer diameter of the second steel pipe 2-2 is equal to the outer diameter of the first steel pipe 1-2. At the same time, the second steel pipe 2-2 is a hollow steel pipe, which can reduce the load on the roof 10 and help reduce the overall load of the rear-mounted components on the roof 10.

[0037] Furthermore, when this utility model is used in the greening renovation of the roof 10, the multiple second strip-shaped notches 8 can be processed to a specified depth according to the design requirements. When the length of the multiple second strip-shaped notches 8 on the second steel pipe 2-2 is less than the length of the multiple first strip-shaped notches 7 on the first steel pipe 1-2, the building surface reference plate 6 is in an inclined posture, avoiding the soil layer from being piled up for the purpose of landscape design, thereby causing the roof 10 to collapse.

[0038] Specific Implementation Method 4: This implementation method is a further limitation of Specific Implementation Methods 1, 2 or 3. The first occupier connecting sleeve 3 and the second occupier connecting sleeve 4 have the same structure. The first occupier connecting sleeve 3 includes a first circular pad 3-1 and a first inner support core strip 3-2. The first circular pad 3-1 has a central hole 3-3 processed along its thickness direction. The first inner support core strip 3-2 is fixedly connected in the central hole 3-3. When the first occupier connecting sleeve 3 is fitted on the edge small column 1 and the number of first strip notches 7 is four, the first inner support core strip 3-2 is a cross-shaped strip. The four ends of the first inner support core strip 3-2 are respectively located in the four first strip notches 7. The inner wall of the central hole 3-3 is attached to the outer wall of the first steel pipe 1-2.

[0039] Furthermore, the first steel pipe 1-2 is a hollow steel pipe, and the upper end of the first steel pipe 1-2 is processed with multiple first strip-shaped notches 7. The first inner support core strip 3-2 on the first occupier connecting sleeve 3 can ensure that the first occupier connecting sleeve 3 is stuck in the four first strip-shaped notches 7, so as to prevent the support plate 5 from slipping or falling off when it is installed, thus ensuring durability and stability when the roof 10 is modified.

[0040] Specific Implementation Method Five: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, or Four. The thickness of the first circular pad 3-1 ranges from 30 to 50 mm. This reduces the weight of the combined raised frame on the roof 10, ensures that the support plate 5 is installed on the first steel pipe 1-2 via the first circular pad 3-1, and facilitates the installation / removal of the first circular pad 3-1 from the first steel pipe 1-2.

[0041] Specific Implementation Method Six: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four or Five. The support plate 5 is processed with multiple connecting holes 9 along its thickness direction. The diameter of the connecting holes 9 is set to match the outer diameter of the first steel pipe 1-2. The support plate 5 is fitted onto the first steel pipe 1-2 through the connecting holes 9. The diameter of the connecting holes 9 is smaller than the outer diameter of the first circular pad 3-1 to avoid slippage or detachment during installation.

[0042] In this embodiment, the shape of the connecting hole 9 can be circular or elliptical to increase the versatility of the support plate 5 assembly. It can accommodate different numbers of first occupier connecting sleeves 3 or second occupier connecting sleeves 4 for occupancy and elevation. When the horizontal positions of each part are different, it also facilitates the smooth assembly of the entire support plate 5 when the plate body is tilted.

[0043] Specific Implementation Method Seven: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, Five, or Six. Multiple reinforcing ribs 11 are evenly arranged on the bottom surface of the support plate 5, and the top side of each reinforcing rib 11 is fixedly connected to the support plate 5. The reinforcing ribs 11 enhance the supporting effect of the support plate 5 itself. When a green landscape is placed behind the roof 10, it can prevent the soil layer from piling up too heavily and collapsing on the support plate 5, while also ensuring the flatness of the support plate 5. It also provides uniform support for other components on the rear-mounted roof 10.

[0044] Combination Figure 13 As shown, this utility model is advantageous for the use of the bottom structure of the subsequent components. It is space-saving and lightweight, and does not affect the normal drainage performance of the roof 10. When a support plate 5 is fitted onto the central small column 2 and the edge small column 1, its position is stabilized by the limiting of the first space-occupying connecting sleeve 3 and the second space-occupying connecting sleeve 4. The excess top structure of the central small column 2 or the edge small column 1 protruding from the top surface of the support plate 5 can be removed by cutting to ensure that the top surface of the support plate 5 is flat. Similarly, after the support plate 5 located at the non-edge of the roof 10 is fitted onto its corresponding four central small columns 2, the excess part of the central small column 2 protruding from the top surface of the support plate 5 is also cut to ensure that the top surface of the support plate 5 is flat, which facilitates the arrangement of other subsequent components.

[0045] The processing length of the first strip-shaped notch 7 and the second strip-shaped notch 8 in this utility model is determined according to the specific design requirements. They can be processed into the same size and length, or they can be processed into different lengths to form different specifications according to the design requirements.

[0046] In this utility model, the support plate 5 can be arranged according to relevant design requirements within the area of ​​the roof 10 enclosed by the parapet wall 12.

[0047] One installation process of this utility model is as follows:

[0048] First, according to the structural design requirements, the construction workers distributed a predetermined number of edge columns 1 around the perimeter of the roof 10. The distance between two adjacent edge columns 1 was determined according to the structural design requirements. Then, a predetermined number of central columns 2 were arranged in the area enclosed by the multiple edge columns 1. Each central column 2 was connected to the non-edge part of the roof 10. According to the local shape height requirements in the design process of the building surface reference plate 6, a predetermined number of first occupant connecting sleeves 3 were fitted one by one onto the edge columns 1 at the corresponding positions. Similarly, a predetermined number of second occupant connecting sleeves 4 were fitted onto each central column 2, thus connecting the parts of the roof 10. The support plates 5 arranged at the edge of the roof 10 are connected to its corresponding two edge small columns 1 and two central small columns 2. The support plates 5 at the edge of the roof 10 are connected to its corresponding edge small columns 1 or central small columns 2 through the connecting holes 9. The support plates 5 arranged at the non-edge of the roof 10 are connected to its corresponding four central small columns 2. The support plates 5 arranged at the non-edge of the roof 10 are connected to its corresponding central small columns 2 through the connecting holes 9. After multiple support plates 5 are arranged and installed in sequence, a building surface base plate 6 is formed. Adjacent support plates 5 can be welded together to further strengthen the connection strength of the building surface base plate 6.
