Abstract

[0002] In frame structures, the cast-in-place floor slabs in areas such as bathrooms and kitchens are often lower than the floor level, requiring localized lowering of the slab. Traditional formwork methods for these lowered areas are complex, especially at corners, easily leading to bulging and inadequate concrete vibration, resulting in construction defects and weak points. Traditional precast support beam structures are not suitable for creating bent or variable cross-section precast components, and the connection between precast components and the cast-in-place concrete slab presents obstacles, resulting in poor slab integrity, susceptibility to cracking, and adverse effects on waterproofing. Therefore, a support beam structure that is easy to form, effectively connects tightly to the cast-in-place concrete slab, has a more stable connection structure less prone to cracking, and offers better waterproofing performance has long been lacking to solve these technical problems. Summary of the Invention
[0003] The purpose of this application is to address the shortcomings and deficiencies of existing support beam structures, such as simple structure, obstacles in the connection between precast components and cast-in-place concrete floor slabs, resulting in poor overall integrity of the floor slab, easy cracking, and adverse effects on subsequent waterproofing performance. The application provides a support beam structure that is structurally reasonable, can effectively and tightly connect with cast-in-place concrete floor slabs, has a more stable connection structure, is less prone to cracking, and improves subsequent waterproofing performance.

Detailed Implementation
[0019] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] See Figures 1 to 3 This application discloses a building support beam structure, comprising a bottom beam 1, characterized in that: a middle beam 3 is fixedly installed on one side of the upper end of the bottom beam 1, a top beam 2 is fixedly installed on the upper end of the middle beam 3, the bottom beam 1 and the top beam 2 are staggered left and right, a steel reinforcement cage 4 is provided inside the bottom beam 1, the top beam 2 and the middle beam 3, the upper surface of the bottom beam 1 is a drop slab casting surface 5, exposed drop slab connecting steel bars 6 are provided on the bottom beam 1, the upper surface of the top beam 2 is an upper casting surface 7, exposed end face connecting steel bars 8 are provided on the upper casting surface 7, and floor slab connecting steel bars 9 are provided at the end of the top beam 2.
[0021] The bottom surface of the bottom beam 1 is perpendicular to the outer surface of the middle beam 3, and the bottom surface of the top beam 2 is perpendicular to the middle beam 3.
[0022] The drop plate connecting steel bar 6, the end face connecting steel bar 8, and the floor slab connecting steel bar 9 are respectively connected and fixed to the steel cage 4.
[0023] Concrete is poured on the surface 5 of the lowered slab and around the reinforcing bars 6 connecting the lowered slab, forming an integral structure with the cast-in-place layer 11 of the lowered slab.
[0024] The reinforcing steel 6 connecting the lowered slab is connected and fixed to the reinforcing steel skeleton in the cast-in-place layer 11 of the lowered slab.
[0025] Concrete is poured on the upper pouring surface 7 and around the floor slab connecting steel bars 9, forming an integral structure with the cast-in-place floor slab layer 10.
[0026] The end face connecting steel bar 8 and the floor slab connecting steel bar 9 are respectively connected and fixed to the steel reinforcement skeleton in the cast-in-place floor slab layer 10.
[0027] The thickness of the bottom beam 1 is less than the thickness of the cast-in-place layer 11 of the drop slab, and the thickness of the top beam 2 is less than or equal to the thickness of the cast-in-place layer 10 of the floor slab.
[0028] This application employs a right-angle bent reinforced concrete support beam structure. The bottom beam and top beam are connected and fixed as a single integral structure via an intermediate beam. By prefabricating the entire structure of the bottom beam, top beam, and intermediate beam in advance and installing it on-site, on-site formwork and pouring are eliminated, simplifying construction. The upper surface of the bottom beam is a drop slab casting surface with exposed drop slab connecting reinforcement bars. The drop slab is poured onto the drop slab casting surface and solidifies to form an integral structure. The upper surface of the top beam is the upper casting surface with exposed floor slab connecting reinforcement bars. The ends of the top beam are equipped with end face connecting reinforcement bars for easy connection with the floor slab reinforcement bars. The upper surface and end face of the top beam, together with the floor slab reinforcement bars, solidify to form an integral structure, resulting in strong overall load-bearing capacity, simplified formwork, and superior waterproofing performance. The specific structure of this application is as follows:
[0029] A middle beam 3 is fixedly connected to one side of the upper end of the bottom beam 1. The middle beam 3 is perpendicular to the bottom beam 1, and the upper surface of the bottom beam 1 is perpendicular to the outer surface of the middle beam 3. A top beam 2 is fixed to the upper end of the middle beam 3. The top beam 2 is perpendicular to the middle beam 3, and the bottom surface of the top beam 2 is perpendicular to the middle beam 3. The bottom beam 1 and the top beam 2 are staggered to the left and right.
[0030] The bottom beam 1, top beam 2, and middle beam 3 are equipped with an integrated steel reinforcement skeleton 4, which is formed by concrete pouring. At the same time, the entire structure of the bottom beam, top beam, and middle beam can be prefabricated and installed directly on site, eliminating the need for formwork and pouring during on-site construction, thus making construction simpler.
[0031] One side of the upper surface of the bottom beam 1 is a drop slab casting surface 5, which solidifies into a single unit with the drop slab cast-in-place layer 11 during the casting process. Exposed drop slab connecting steel bars 6 are provided on the side of the bottom beam 1 connecting to the drop slab cast-in-place layer 11. One end of the drop slab connecting steel bar 6 is connected to the internal steel reinforcement skeleton 4 of the bottom beam 1, and the other end is connected and fixed to the steel reinforcement skeleton within the drop slab cast-in-place layer 11. Concrete is poured on the drop slab casting surface 5 and around the drop slab connecting steel bars 6, forming an integral structure with the drop slab cast-in-place layer 11. This results in the thickness of the bottom beam 1 being less than the thickness of the drop slab cast-in-place layer 11, and also facilitates subsequent waterproofing.
[0032] The upper surface of the top beam 2 is the upper casting surface 7. The upper casting surface 7 is provided with exposed end-face connecting steel bars 8. One end of the end-face connecting steel bars 8 is connected to the steel reinforcement skeleton 4 inside the top beam 2, and the other end of the end-face connecting steel bars 8 is connected and fixed to the steel reinforcement skeleton inside the cast-in-place floor slab 10.
[0033] The top beam 2 is connected to the cast-in-place floor slab 10 by floor slab connecting reinforcement 9. One end of the floor slab connecting reinforcement 9 is connected to the reinforcement cage 4 inside the top beam 2, and the other end of the floor slab connecting reinforcement 9 is connected and fixed to the reinforcement cage inside the cast-in-place floor slab 10. Concrete is poured on the upper pouring surface 7 and around the floor slab connecting reinforcement 9, forming an integral structure with the cast-in-place floor slab 10. The thickness of the top beam 2 is less than or equal to the thickness of the cast-in-place floor slab 10.

It should not be considered that the specific implementation of this application is limited to these descriptions. For those skilled in the art, there will be various simple substitutions, improvements and changes to this application without departing from the concept of this application.
