Abstract
Description
Technical Field
[0001] This utility model relates to the field of reinforced concrete frame structure technology, and in particular to a tensile, shear and torsion resistant reinforced concrete frame beam structure. Background Technology
[0002] A reinforced concrete frame beam is a beam-like member in a reinforced concrete frame structure, connected to frame columns at both ends, primarily bearing vertical and horizontal loads. The concrete frame beam and frame columns are interconnected, forming the spatial skeleton of the building. Concrete frame beams, formed by a steel frame and concrete, possess excellent mechanical properties, economic performance, and durability, and are widely used in construction engineering. However, existing reinforced concrete frame beams have many shortcomings. Frame beams used in buildings are typically in humid environments. Because the surface of existing frame beams is a planar structure, the drainage efficiency of the reinforced concrete surface is very low, and water accumulates over time in gaps and connections, thus accelerating the corrosion of the frame beam and damaging the concrete. Utility Model Content

[0014] Compared with the prior art, this utility model provides a tensile, shear, and torsional reinforced concrete frame beam structure, which has the following beneficial effects:
[0015] 1. This utility model solves the problem of water corrosion and concrete damage to frame beams in humid environments by setting drainage channels on the outer side of the middle of the concrete structure and a drainage surface on the concrete surface. The drainage channel accelerates the discharge of water to the underside of the reinforced concrete frame beam, preventing water from accumulating on the frame beam surface, reducing water on the frame beam surface, accelerating the drying speed, and reducing water corrosion of the steel frame and damage to the concrete. This improves the strength of the steel frame and concrete structure, and plays a positive role in improving the tensile, shear and torsional resistance of the frame beam. By setting up a reinforcing steel structure, the development of diagonal cracks can be effectively restrained, allowing the concrete to better transmit shear force, improving the shear resistance of the drainage channel and the frame beam as a whole, and improving the overall structural strength.

[0021] This utility model relates to a tensile, shear, and torsional resistant reinforced concrete frame beam structure, such as... Figure 1-4 As shown, the structure includes a steel frame 1, with concrete poured inside the steel frame 1 to form a concrete body 2. A drainage channel 3 is circumferentially formed on the outer side of the middle of the concrete body 2. A reinforcing steel structure is installed in the middle of the steel frame 1. A flow guiding structure, including a drainage surface 4, is provided on the surface of the concrete body 2. The top of the drainage surface 4 is inclined and communicates with the drainage channel 3. The steel frame 1 and the concrete body 2, formed by the concrete pouring inside the steel frame 1, constitute a frame beam. The drainage channel 3 and the drainage surface 4, with their inclined tops, connect to the drainage channel 3. The inclined structure guides water into the drainage channel 3, which accelerates the drainage of water below the reinforced concrete frame beam, preventing water from accumulating on the surface of the frame beam, reducing water on the surface of the frame beam, accelerating the drying speed, and reducing water corrosion of the steel frame 1 and damage to the concrete structure. This solves the problem of frame beams being prone to corrosion and concrete damage in humid environments, and also improves the strength of the steel frame 1 and the concrete structure 2. It plays a positive role in improving the tensile, shear, and torsional resistance of the frame beam. By setting up a reinforcing steel structure, the development of inclined cracks can be effectively restrained, allowing the concrete to better transmit shear force, improving the shear resistance of the drainage channel 3 and the frame beam as a whole, and improving the overall structural strength.
[0022] In an embodiment of this utility model, the steel frame 1 includes stirrups 101, longitudinal steel bars 102, stirrups 103, and web reinforcement 104.

The stirrups 103 are sleeved on the outside of the stirrups 101 and the longitudinal steel bars 102. By setting the stirrups 101, longitudinal steel bars 102, stirrups 103, and web reinforcement 104, the stirrups 101 form a steel skeleton, the longitudinal steel bars 102 bear the tensile force generated by bending moment and serve as the main load-bearing steel bars, the stirrups 103 are used to fix the stirrups 101 and the longitudinal steel bars 102 to enhance the shear resistance of the frame beam, and the web reinforcement 104 enhances the structural strength on both sides of the frame beam and enhances the torsional and shear resistance.

The reinforced steel structure is reinforced stirrups 1031 set in the middle and both ends of the steel frame 1, and non-dense stirrups 1032 are set at both ends of the steel frame 1. By setting dense stirrups 1031, the shear resistance of the frame beam at both ends and the middle is improved, and the load-bearing capacity of the middle of the beam is also improved.
[0024] In this embodiment of the utility model, the two ends of the reinforcing bar 101 and the longitudinal reinforcing bar 102 pass through the two ends of the concrete structure 2 and are provided with bending parts 5. By providing bending parts 5, the anchorage capacity of the two ends of the frame beam is enhanced.
[0025] In an embodiment of this utility model, a triangular drainage section 6 is provided at the bottom of the drainage trough 3. By providing the triangular drainage section 6, water can flow through the drainage section 6 to both sides of the drainage trough 3, thereby improving the drainage efficiency inside the drainage trough 3.
[0026] In an embodiment of this utility model, the drainage section 6 is an octagonal structure and is symmetrical about the four sides of the frame beam. By setting the drainage section 6 to be an octagonal structure and symmetrical about the four sides of the frame beam, it is easier to improve the structural strength inside the drainage channel 3.
[0027] In an embodiment of this utility model, the flow guiding structure also includes an anti-clogging space 7 disposed between the drainage surface 4 and the drainage channel 3. By providing the anti-clogging space 7, it is easy to discharge impurities in the water and avoid impurities and water clogging between the drainage surface 4 and the drainage channel 3.
[0028] In an embodiment of this utility model, a base 7 is provided at the end of the drainage surface 4 away from the drainage trough 3. By providing the base 7, the structural strength at both ends of the frame beam is enhanced.
[0029] In this embodiment of the utility model, there are three longitudinal steel bars 102 and two stirrups 101. By setting the number of longitudinal steel bars 102 to three, it is easier to improve the bending resistance and ductility of the frame beam. By setting the number of stirrups 101 to two and setting them on both sides of the steel frame 1, it is easier to form a force balance system with the longitudinal reinforcing bars at the bottom of the beam.
[0030] In this embodiment of the invention, there are four drainage surfaces 4, which are respectively set on the four surfaces of the concrete casting. By setting the number of drainage surfaces 4 to four and respectively set on the four surfaces of the concrete casting, the drainage efficiency of the four surfaces of the frame beam can be improved.
[0031] In use, firstly, a steel skeleton is formed by the stirrups 101, and the longitudinal steel bars 102 bear the tensile force generated by the bending moment and serve as the main load-bearing steel bars. Stirrups 103 are used to fix the stirrups 101 and the longitudinal steel bars 102. The web bars 104 enhance the structural strength on both sides of the frame beam and enhance the torsional and shear resistance. Concrete is poured into the steel frame 1 to form a frame beam. Water on the surface of the frame beam flows into the drainage trough 3 through the inclined structure at the top of the drainage surface 4.
