Description

Technical Field

[0001] This utility model relates to the field of building structures, and in particular to a composite frame beam structure of steel beam and concrete beam. Background Technology

[0002] A skylight roof is a structure composed of translucent panels and a supporting system. It does not share the load or load of the main structure and provides lighting and other related physical properties. Skylight roofs should use transparent or semi-transparent materials, such as glass or polycarbonate panels, to ensure sufficient natural light enters the interior. The design must consider the area and location of the skylight to ensure uniform lighting in all corners of the interior. Lighting efficiency can be improved by increasing the number of translucent surfaces and optimizing the location and shape of openings. The structural design of a skylight roof must ensure it can withstand its own weight, wind loads, snow loads, and other external loads. Therefore, a stable frame beam structure is required to support the roof. Currently, concrete-cast frame beam structures are commonly used, offering high support strength. However, the dense formwork and reinforcement system processes prolong the construction period and are not conducive to reducing construction costs, thus requiring optimization and improvement. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a composite frame beam structure consisting of steel beams and concrete beams.

[0004] The technical solution of this utility model is: a steel beam-concrete beam composite frame beam structure, including a concrete beam reinforcement system, embedded parts, and steel beams. The embedded parts include an inner plate and an outer plate. The inner and outer plates are the same size and are arranged parallel to each other. A horizontal brace is fixedly connected between the inner and outer plates. The horizontal brace passes through the longitudinal bars of the beam reinforcement system and is located between adjacent annular stirrups. The outer plate is supported on the outside of the longitudinal bars. The length of the outer plate and the inner plate matches the cross-sectional dimensions of the beam reinforcement system. The inner plate is supported on the inside of the longitudinal bars. The two ends of the steel beam are respectively connected to the inner plates on the beam reinforcement system on both sides. The number of steel beams is set according to the dimensions of the frame structure.

[0005] Preferably, the inner plate has side baffles on both sides of its edge, the side baffles are vertically connected to the inner plate as a whole, the side baffles form a sliding groove structure on the inner plate, and a limiting bottom plate is provided at the lower end of the two side baffles.

[0006] Preferably, both ends of the steel beam are provided with vertical end plates, which can be vertically inserted into the sliding grooves formed by the baffles on both sides. The vertical end plates are fitted between the baffles on both sides, and the bottom surface of the vertical end plates is supported on the limiting baffles, which are arranged horizontally.

[0007] Preferably, the steel beam is an arched beam, which includes an upper arc-shaped beam body and a lower arc-shaped beam body, with a certain distance between the upper arc-shaped beam body and the lower arc-shaped beam body, and diagonal bracing plates connected end to end are densely arranged between the upper arc-shaped beam body and the lower arc-shaped beam body.

[0008] Preferably, a rubber pad is provided between the vertical end plate and the limiting base plate, and the size of the rubber pad matches the size of the bottom surface of the vertical end plate.

[0009] Preferably, the cross brace includes an upper rod, a middle rod, and a lower rod. The upper rod, middle rod, and lower rod are each arranged in pairs. The upper rod passes laterally through the upper longitudinal rib, the middle rod passes laterally through the middle longitudinal rib, and the lower rod passes laterally through the lower transverse rib.

[0010] Preferably, the inner plate has through holes, and the cross brace is inserted into the through holes and fixed by welding. The cross brace extends slightly out of the cross brace to improve the welding strength.

[0011] The beneficial technical effects of this utility model are as follows: This utility model provides docking support for steel beams by setting embedded parts in the beam reinforcement system, so that the steel beams can be directly docked and fixed with the beam reinforcement system. After the beam reinforcement system is poured with concrete, it forms an integrated anchoring structure with the steel beam, forming a frame beam support structure of concrete beam and steel beam combination. While ensuring the support strength for the skylight roof, it is not necessary to pour concrete over a large area, which helps to ensure the construction progress and reduce construction costs.

[0019] Example 1, see appendix Figures 1-3 A composite frame beam structure of steel beam and concrete beam includes a concrete beam reinforcement system 1, embedded parts 2, and steel beam 3. The embedded parts 2 include an inner plate 21 and an outer plate 22. A horizontal brace is fixedly connected between the inner plate and the outer plate. The spacing between the inner plate 21 and the outer plate 22 is the same as the width of the concrete beam. The length of the horizontal brace is slightly greater than the width of the concrete beam. The horizontal brace passes through the longitudinal reinforcement 11 of the beam reinforcement system 1 and is located between adjacent annular stirrups 12. The outer plate 22 is supported on the outside of the longitudinal reinforcement 11, and the inner plate 21 is supported on the inside of the longitudinal reinforcement 11. The inner plate 21 and the outer plate 22 are fixed to both sides of the beam reinforcement system 1 by the horizontal brace. After the concrete is poured, the inner plate 21 and the outer plate 22 are anchored between the concrete and the reinforcement. The two ends of the steel beam 3 are respectively connected to the inner plate 21 on both sides of the beam reinforcement system 1. The bottom of the beam reinforcement system 1 is connected to the column reinforcement system 4. The longitudinal reinforcement 11 of the column reinforcement system 4 is inserted into the beam reinforcement system 1.

[0020] The steel beam 3 is an arched beam, which includes an upper arc-shaped beam body 32 and a lower arc-shaped beam body 33. The upper arc-shaped beam body 32 and the lower arc-shaped beam body 33 are densely connected with diagonal bracing plates 34. The diagonal bracing plates 34 connected with the upper arc-shaped beam body 32 and the lower arc-shaped beam body 33 form a continuous triangular support structure, which ensures the strength of the steel beam 3 while reducing the self-weight of the steel beam 3, which helps to save material costs and meet the design requirements of lightweighting.

[0021] A rubber pad is provided between the vertical end plate 31 and the limiting base plate 212. The rubber pad forms a flexible support between the steel beam 3 and the embedded part 2, which plays a role in shock absorption and seismic resistance.

[0022] The cross brace includes an upper body 23, a middle body 24, and a lower body 25. The upper body 23 passes laterally through the upper longitudinal reinforcement 11, the middle body 24 passes laterally through the middle longitudinal reinforcement 11, and the lower body 25 passes laterally through the lower transverse reinforcement. The dense arrangement of upper, middle, and lower body braces increases the number of support points for the embedded part 2 within the beam reinforcement system 1, thereby further improving its embedded anchorage stability.

[0023] The inner plate 21 has through holes, and the cross braces are inserted into the through holes and fixed by welding. The cross braces can be welded to both ends of the through holes to improve the connection strength between the cross braces and the inner plate 21, thereby ensuring the support strength of the steel beam 3.

[0024] This embodiment provides a connecting support for the steel beam 3 by setting embedded parts 2 in the beam reinforcement system 1, so that the steel beam 3 can be directly connected and fixed to the beam reinforcement system 1. After the beam reinforcement system 1 is poured with concrete, it forms an integrated anchoring structure with the steel beam 3, forming a frame beam support structure composed of concrete beam and steel beam 3. While ensuring the support strength for the skylight roof, it is not necessary to pour concrete over a large area, which helps to ensure the construction progress and reduce construction costs.

[0025] Example 2, see appendix Figures 4-6 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that: side baffles 211 are provided on both sides of the inner plate 21, and the side baffles form a sliding groove structure on the inner plate 21. During the docking construction, lubricating oil is applied between the side baffles 211 and the inner plate 21. A limiting bottom plate 212 is provided at the lower end of the two side baffles 211. Vertical end plates 31 are provided at both ends of the steel beam 3. The vertical end plates are fitted between the two side baffles 211. The lubricating effect of the lubricating oil facilitates the smooth insertion of the vertical end plates 31 into the sliding groove between the beam baffles. The bottom surface of the vertical end plates 31 is supported on the limiting baffles. This embodiment uses a sliding fitting method to dock and fix the steel beam 3 and the inner plate 21. During construction, the docking can be quickly achieved by suspending with a crane. It has the advantages of convenient docking and high construction effect, and at the same time, it helps to improve the safety of construction.
