Description

Technical Field

[0001] This utility model relates to the field of mother-and-child beam installation technology, specifically a type of cantilevered, support-free building structure with mother-and-child beams. Background Technology

[0002] In modern building construction, cantilever structures are a common architectural form, widely used in various building scenarios such as balconies, canopies, and eaves. Traditional cantilever structure construction typically requires a large number of support systems to ensure structural stability and safety during construction. However, the construction and dismantling of these support systems are not only time-consuming and labor-intensive but also increase construction costs and risks. Furthermore, the presence of support systems can also impose certain limitations on the use of space on the construction site and subsequent construction procedures.

[0003] While existing cantilever structure construction technologies can meet the needs of building construction to a certain extent, they still have some shortcomings in terms of construction efficiency, cost control, and safety. For example, in traditional cantilever structure construction, the erection and dismantling of the support system requires a significant amount of manpower and time. Furthermore, the stability of the support system can be affected by various factors during construction, such as construction loads and environmental factors, leading to increased construction safety risks. In addition, the presence of the support system can also restrict the use of space on the construction site, affecting the smooth progress of subsequent construction procedures.

[0004] Therefore, a type of cantilevered, bracing-free building structure with a parent-child beam is needed to improve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a cantilevered, support-free building structure with a parent-child beam to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A type of cantilevered, bracing-free building structure with a parent-child beam includes beams and columns. An assembly mechanism is fixedly provided at the upper end of the beams and columns. The assembly mechanism includes beam fittings and clamping sleeves. Precast main beams are fixedly provided inside the clamping sleeves on both sides of the assembly mechanism. The parent beam and child beam are respectively fixedly provided on the beam fittings on both sides of the assembly mechanism.

[0008] As a preferred embodiment of this utility model, the beam assembly is fixedly provided with clamping sleeves on both sides, and the connection between the beam assembly and the clamping sleeves is fixed by a number of triangular reinforcing ribs.

[0009] As a preferred embodiment of this utility model, the clamping sleeve is concave, and the upper end of the clamping sleeve is fixedly provided with a second mounting protrusion. The clamping sleeves on both sides are fixedly connected by a second mounting bolt on the surface of the second mounting protrusion.

[0010] As a preferred embodiment of this utility model, both the clamping sleeve and the lower end of the beam assembly are fixedly provided with column mounting plates, and the column mounting plates are fixedly connected to the beam and column by bolts.

[0011] As a preferred embodiment of this utility model, the connection between the clamping sleeve and the beam assembly and the column mounting plate is fixed by two triangular reinforcing ribs.

[0012] As a preferred embodiment of this utility model, the beam assembly is a hollow square sleeve, and the beam assembly is adapted to the size of the sub-beam and the parent beam. Trapezoidal reinforcing ribs are fixedly provided on both sides of the beam assembly.

[0013] As a preferred embodiment of this utility model, the upper end of the beam assembly is fixedly provided with a mounting protrusion, and the beam assemblies on both sides are fixedly connected by mounting bolts on the surface of the mounting protrusion.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model eliminates the need for a large number of support frames to ensure stability during construction, which is usually required for traditional cantilever structures. This structure achieves support-free construction through a stable connection between the assembly mechanism and the beams and columns. This greatly reduces the work of setting up and dismantling support frames during construction, shortens the construction cycle, and improves construction efficiency.

[0016] 2. The precast main beam, sub-beam and parent beam of this utility model are quickly installed through the assembly mechanism, which reduces on-site wet work and makes the construction process simpler and more efficient. The connection method of the clamping sleeve and beam assembly is simple and can be completed by bolt connection, which is convenient for on-site operation.

[0017] 3. The clamping sleeve of this utility model is fixedly connected by mounting bolt two, the beam assembly is fixedly connected by mounting bolt one, and the column mounting plate is fixedly connected to the beam and column by bolt three, forming a stable structure with multiple connections. At the same time, the setting of triangular reinforcing rib one and triangular reinforcing rib two further enhances the connection strength and overall stability of the assembly mechanism, effectively disperses and transmits stress, and prevents structural damage caused by local stress concentration.

[0030] Please see Figure 1-7 This utility model provides a technical solution:

[0031] A type of cantilevered, bracing-free building structure with a parent-child beam includes a beam-column 16. An assembly mechanism 4 is fixedly installed at the upper end of the beam-column 16. The assembly mechanism 4 includes a beam-mounting accessory 5 and a clamping sleeve 10. A precast main beam 1 is fixedly installed inside the clamping sleeve 10 on both sides of the assembly mechanism 4. A child beam 2 and a parent beam 3 are respectively fixedly installed on the beam-mounting accessory 5 on both sides of the assembly mechanism 4. First, the precast main beam 1 is fixed by the clamping sleeve 10. The clamping sleeve 10 has a concave structure and can tightly wrap around both ends of the precast main beam 1. The clamping sleeves 10 on both sides are connected together by mounting bolts 8, thereby achieving a stable clamping of the precast main beam 1 and ensuring that it will not shift during subsequent construction.

[0032] Next, the sub-beam 2 and the mother beam 3 are installed into the beam assembly 5 respectively; the beam assembly 5 is a hollow square sleeve, the internal dimensions of which are adapted to the sub-beam 2 and the mother beam 3, and can accurately accommodate the two; the beam assembly 5 on both sides is connected together by the mounting bolts 7 to further fix the position of the sub-beam 2 and the mother beam 3.

[0033] As an example of this utility model, clamping sleeves 10 are fixedly provided on both sides of the beam assembly 5. The connection between the beam assembly 5 and the clamping sleeves 10 is fixed by a number of triangular reinforcing ribs 11. At the same time, the beam assembly 5 and the clamping sleeves 10 are fixed by a number of triangular reinforcing ribs 11. These triangular reinforcing ribs 11 are distributed at the connection between the beam assembly 5 and the clamping sleeves 10, which further enhances the connection strength between the two and ensures that the beam assembly 5 and the clamping sleeves 10 can work together to bear the load during the cantilever process.

[0034] As an example of this utility model, the clamping sleeve 10 is concave, and the upper end of the clamping sleeve 10 is fixedly provided with a mounting protrusion 9. The clamping sleeves 10 on both sides are fixedly connected by mounting bolts 8 on the surface of the mounting protrusion 9.

[0035] As an example of this utility model, both the clamping sleeve 10 and the beam assembly 5 are fixedly provided with column mounting plates 14 at their lower ends. The column mounting plates 14 are fixedly connected to the beam column 16 by bolts 13. The column mounting plates 14 are fixedly connected to the beam column 16 by bolts 13, thereby firmly installing the entire assembly mechanism 4 on the upper end of the beam column 16. This connection method makes the assembly mechanism 4 and the beam column 16 form a whole, providing a stable support foundation for the subsequent cantilever structure.

[0036] As an example of this utility model, the connection between the clamping sleeve 10 and the beam mounting 5 and the column mounting plate 14 is fixed by triangular reinforcing ribs 2 12. In order to further enhance the stability of the structure, the connection between the beam mounting 5 and the clamping sleeve 10 and the column mounting plate 14 is fixed by triangular reinforcing ribs 2 12. The triangular structure of the triangular reinforcing ribs 2 12 can effectively disperse and transfer stress, improve the load-bearing capacity of the connection, and prevent structural damage caused by local stress concentration.

[0037] As an example of this utility model, the beam fitting 5 is a hollow square sleeve, and the dimensions of the beam fitting 5 are adapted to the sub-beam 2 and the mother beam 3. Trapezoidal reinforcing ribs 15 are fixed on both sides of the beam fitting 5. After the entire structure is installed, the mother beam 3 is connected to the beam column 16 through the beam fitting 5, and forms a cantilever structure with the assistance of the sub-beam 2. The mother beam 3, as the main load-bearing component, bears the load on the outside of the building and transfers it to the beam column 16.

[0038] Sub-beam 2 serves as an auxiliary support, sharing the load with the main beam 3 and improving the overall stability of the cantilever structure. Since trapezoidal reinforcing ribs 15 are fixed on both sides of the beam assembly 5, these trapezoidal reinforcing ribs 15 can further enhance the bending and shear resistance of the beam assembly 5, ensuring that the beam assembly 5 can effectively transfer the load to the beam and column 16 during the cantilever process without deformation or damage.

[0039] As an example of this utility model, the upper end of the beam assembly 5 is fixedly provided with a mounting protrusion 6, and the beam assembly 5 on both sides is fixedly connected by mounting bolts 7 on the surface of the mounting protrusion 6.

[0040] Working principle: When using,

[0041] First, the precast main beam 1 is fixed by clamping sleeve 10. The clamping sleeve 10 has a concave structure, which can tightly wrap around both ends of the precast main beam 1. The clamping sleeves 10 on both sides are connected together by mounting bolts 2 8, thereby achieving a stable clamping of the precast main beam 1 and ensuring that it will not shift during subsequent construction.

[0042] Next, the sub-beam 2 and the mother beam 3 are installed into the beam assembly 5 respectively; the beam assembly 5 is a hollow square sleeve, whose internal dimensions are adapted to the sub-beam 2 and the mother beam 3, and can accurately accommodate the two; the beam assembly 5 on both sides is connected together by the mounting bolts 7 to further fix the position of the sub-beam 2 and the mother beam 3.

[0043] Both the beam assembly 5 and the clamping sleeve 10 are equipped with column mounting plates 14 at their lower ends; the column mounting plates 14 are fixedly connected to the beam and column 16 by bolts 3 13, thereby firmly installing the entire assembly mechanism 4 on the upper end of the beam and column 16; this connection method makes the assembly mechanism 4 and the beam and column 16 form a whole, providing a stable support foundation for the subsequent cantilever structure.

[0044] To further enhance the stability of the structure, triangular reinforcing ribs 2 12 are used to fix the beam assembly 5 and clamping sleeve 10 at the connection with the column mounting plate 14. The triangular structure of the triangular reinforcing ribs 2 12 can effectively disperse and transfer stress, improve the load-bearing capacity of the connection, and prevent structural damage caused by local stress concentration.

[0045] Meanwhile, the beam assembly 5 and the clamping sleeve 10 are fixed together by a number of triangular reinforcing ribs 11. These triangular reinforcing ribs 11 are distributed at the connection between the beam assembly 5 and the clamping sleeve 10, which further enhances the connection strength between the two and ensures that the beam assembly 5 and the clamping sleeve 10 can work together to bear the load during the cantilever process.

[0046] Once the entire structure is installed, the main beam 3 is connected to the beam-column 16 via the beam assembly 5, and forms a cantilever structure with the assistance of the sub-beam 2; the main beam 3, as the main load-bearing component, bears the load on the outside of the building and transfers it to the beam-column 16.

[0047] Sub-beam 2 serves as an auxiliary support, sharing the load with the main beam 3 and improving the overall stability of the cantilever structure. Since trapezoidal reinforcing ribs 15 are fixed on both sides of the beam assembly 5, these trapezoidal reinforcing ribs 15 can further enhance the bending and shear resistance of the beam assembly 5, ensuring that the beam assembly 5 can effectively transfer the load to the beam and column 16 during the cantilever process without deformation or damage.

[0048] The entire cantilever structure is supported by assembly mechanism 4, enabling support-free construction. This support-free design greatly reduces the number of supporting components during construction, improves construction efficiency, and also reduces construction costs and risks. Through reasonable structural design and connection methods, the building structure can achieve the cantilever function of the main beam while ensuring safety and stability, thus meeting the needs of building construction.

[0049] 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.
