Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a ribbed beam plate. Background Technology

[0002] Composite slabs, as a common structural component, are widely used in various construction projects. They typically consist of precast slabs and cast-in-place concrete layers, connected to form a unified structure to improve the load-bearing capacity and overall performance of the floor slab. However, traditional composite slab designs have some inherent problems, especially when the floor span is large.

[0003] Traditional composite slabs are typically designed with a flat bottom and exposed reinforcement on four or two sides. This design performs reasonably well when the floor span is small, but as the floor span increases, the load-bearing capacity of the composite slab decreases significantly. To meet load-bearing requirements, the floor slab thickness often needs to be increased, which not only increases material costs but may also lead to an increase in the overall weight of the building, adversely affecting structural safety.

[0004] Furthermore, the exposed reinforcement design of traditional composite slabs also brings significant challenges to construction. When the exposed reinforcement encounters the beam reinforcement, complex reinforcement crossing and tying work is required, which not only increases construction time but also may lead to construction quality problems due to improper operation. Especially in high-rise buildings or large public buildings, where construction difficulty and schedule requirements are even higher, the traditional composite slab design often becomes a bottleneck restricting project progress and quality.

[0005] Therefore, in view of the problems existing in the prior art, it is necessary to propose a new composite slab design to solve the problems of exposed reinforcement and difficult installation of composite slabs, while improving the load-bearing performance and construction efficiency of composite slabs. Utility Model Content

[0006] The purpose of this utility model is to provide a ribbed slab to solve the technical problems of exposed reinforcing bars and difficult installation in existing composite slabs. The specific technical solution is as follows:

[0007] This utility model provides a ribbed beam plate, which is a precast reinforced concrete structure with a bottom surface, a top surface, and side surfaces, and the reinforcing bars are not exposed on the side surfaces and bottom. The ribbed beam plate includes a floor slab and two ribs. The two ribs are fixed to the floor slab on both sides along its length direction, facing the bottom surface of the floor slab. The two ends of the reinforcing bars of the ribs are provided with sleeves for installation, and the open end face of the sleeve is flush with the concrete end face of the rib.

[0008] A further improvement of this utility model rib beam plate is that the reinforcing bars in the rib beam are in the form of a reinforcing cage, which includes multiple first longitudinal bars and multiple rings of stirrups. The multiple rings of stirrups are wrapped around the outer periphery of the multiple first longitudinal bars and the top of the stirrups are exposed on the top surface of the precast reinforced concrete structure. The sleeve is provided at the end of the first longitudinal bar.

[0009] A further improvement of this utility model ribbed plate is that the steel cage is provided with at least two layers of first longitudinal bars along the height direction of the rib, the number of first longitudinal bars at the bottom layer is at least two, and the at least two first longitudinal bars are spaced apart.

[0010] A further improvement of the rib plate of this utility model is that the sleeve is a threaded sleeve with threads at both ends, and the end of the first longitudinal rib is provided with a thread that is compatible with the threaded sleeve.

[0011] A further improvement of this utility model ribbed slab is that the reinforcement of the floor slab includes multiple second longitudinal bars and multiple bottom reinforcing bars, the multiple second longitudinal bars are spaced apart, and the multiple bottom reinforcing bars are vertically spaced at the bottom of the multiple second longitudinal bars.

[0012] The application of the technical solution of this utility model has the following beneficial effects:

[0013] This utility model of a ribbed beam slab is particularly suitable for composite floor slabs with large spans. By bearing the floor load through the ribs, the stress on the floor slab is effectively distributed, significantly improving the load-bearing performance of the composite slab. When the floor slab span increases, the ribbed beam slab can maintain good structural stability without the need to increase the floor slab thickness, thus saving material costs. The design of the ribbed beam slab with no reinforcement on four sides avoids the complex intersection and binding work of beam reinforcement after reinforcement is exposed in traditional composite slabs, greatly reducing construction difficulty. During construction, the ribbed beam slab is easy and quick to install, reducing construction time and improving project progress. Because the bottom reinforcement of the ribbed beam of this utility model has a pre-reserved threaded sleeve, the reinforcement is connected to the sleeve after installation. This design not only simplifies the construction process but also improves construction efficiency. The absence of reinforcement at both ends of the ribbed beam makes the installation process smoother and reduces construction delays caused by reinforcement intersections and binding. The design of the ribbed beam slab allows the floor load to be transferred more evenly to the ribbed beam, with the ribbed beam bearing the load as a whole, enhancing the structural stability. This design also helps to improve the seismic performance of the floor slab, providing strong protection for building safety. Because the ribbed plate design simplifies the construction process and reduces potential problems during construction, it lowers subsequent maintenance costs. At the same time, the ribbed plate has a longer service life, providing more durable and stable structural support for the building.

[0014] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0025] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] See Figures 1 to 8 As shown, a ribbed slab is a precast reinforced concrete structure with a bottom surface, a top surface, and side surfaces, and the reinforcing bars are not exposed on the side surfaces and bottom. The ribbed slab includes a floor slab 1 and two ribs 2. The two ribs 2 are fixed to both sides of the floor slab 1 along its length and both face the bottom surface of the floor slab 1. The two ends of the reinforcing bars of the ribs 2 are provided with sleeves 7 for installation, and the open end face of the sleeves 7 is flush with the concrete end face of the ribs 2.

[0027] like Figure 7 and8 As shown, since the rib plate of this utility model does not have reinforcing bars on its four sides, it is preferable to install it in conjunction with the main beam with a notch. The external reinforcing bars 9 are then connected to the notch position through the sleeve 7 to achieve the connection with the main beam. Concrete is then poured in place to fix it to the main beam.

[0028] Preferred, such as Figure 3 As shown, the reinforcing bars within the rib beam 2 form a reinforcing cage structure. The reinforcing cage includes multiple first longitudinal bars 3 and multiple rings of stirrups 4. The multiple rings of stirrups 4 are wrapped around the outer periphery of the multiple first longitudinal bars 3, with the top of the stirrups 4 protruding above the top surface of the precast reinforced concrete structure. The sleeve 7 is located at the end of the first longitudinal bars 3. By having the top of the stirrups 4 protruding above the precast concrete and binding the rib beam top reinforcement 8, the construction of the cast-in-place concrete on the top surface of the rib beam slab is satisfied, forming a reinforced concrete structure with the cast-in-place concrete.

[0029] Preferably, the reinforcing cage has at least two layers of first longitudinal reinforcement 3 along the height direction of the rib beam 2, with at least two first longitudinal reinforcement 3 located at the bottom layer, and these at least two first longitudinal reinforcement 3 are spaced apart. In this embodiment, the cross-section of the rib beam 2 is rectangular, with two first longitudinal reinforcement 3 located at the two corners of the bottom of the rib beam 2, thereby improving the shear resistance of the rib beam 2.

[0030] Preferred, such as Figures 5-8 As shown, the sleeve 7 is a threaded sleeve with threads at both ends, and the end of the first longitudinal rib 3 has a thread that matches the threaded sleeve. The threaded connection facilitates installation, and the threaded sleeve enables the installation and force transmission of the rib plate.

[0031] Preferred, such as Figure 4 As shown, the floor slab 1 has multiple second longitudinal bars 6 and multiple bottom reinforcing bars 5. The multiple second longitudinal bars 6 are spaced apart, and the multiple bottom reinforcing bars 5 are vertically spaced at the bottom of the multiple second longitudinal bars 6. In this embodiment, the floor slab 1 is not in the direction of stress and therefore does not require exposed reinforcement. Through the arrangement of the second longitudinal bars 6 and the bottom reinforcing bars 5, the force transmission of the floor slab 1 is achieved, as shown... Figure 1 As shown in the load transfer direction A, the load of the floor slab 1 is transferred to the two side rib beams 2, and the rib beams 2 bear the floor slab load.

[0032] This utility model of a ribbed beam slab is particularly suitable for composite floor slabs with large spans. By using ribs 2 to bear the floor load, the stress on the floor slab is effectively distributed, significantly improving the load-bearing performance of the composite slab. When the floor slab span increases, the ribbed beam slab can maintain good structural stability without requiring additional floor slab thickness, thus saving material costs. The design of the ribbed beam slab with no reinforcement on four sides avoids the complex intersection and binding work of beam reinforcement encountered after reinforcement is exposed in traditional composite slabs, greatly reducing construction difficulty. During construction, the ribbed beam slab is easy and quick to install, reducing construction time and improving project progress. Because the bottom reinforcement of the ribbed beam 2 of this utility model has a pre-reserved threaded sleeve, the reinforcement is connected to the sleeve 7 after installation. This design not only simplifies the construction process but also improves construction efficiency. The absence of reinforcement at both ends of the ribbed beam 2 makes the installation process smoother, reducing construction delays caused by reinforcement intersections and binding. The design of the ribbed beam slab allows the floor load to be transferred more evenly to the ribbed beam 2, with the ribbed beam 2 bearing the load as a whole, enhancing structural stability. This design also helps improve the seismic performance of the floor slab, providing strong protection for building safety. Because the ribbed slab design simplifies the construction process and reduces potential problems during construction, it lowers later maintenance costs. At the same time, the ribbed slab has a longer service life, providing more durable and stable structural support for the building.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
