Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving and lightweight steel structure concrete precast floor beam connections, and specifically to an energy-saving and lightweight steel structure concrete precast floor beam connection structure. Background Technique

[0002] The floor slab is an important part of the overall building structure. It not only bears vertical loads but also transfers the horizontal loads generated by seismic actions and wind loads to the seismic resistance system. Traditional energy-saving and lightweight steel structure concrete floor slabs exhibit excellent mechanical properties. However, during the construction process, a large number of workers are still required for on-site formwork production, steel bar binding, and concrete pouring, etc. There are problems such as cumbersome construction, large workload, and low construction efficiency. In addition, with the shortage of labor, the required labor cost has increased significantly; large-scale on-site wet operations cause environmental pollution.

[0003] During the docking and installation process of existing floor slabs through two floor slabs and a precast beam made of fly ash material arranged in the middle, although rapid installation can be carried out on-site, during this process, since one end of the two floor slabs is at the top of the precast beam, during the installation process of the two ends of the floor slabs away from each other, the center of gravity will shift, resulting in possible bending of the ends of the precast steel bars at the top of the precast beam, affecting the installation quality of the precast floor slab. Summary of the Invention

[0004] The purpose of the present invention is to provide an energy-saving and lightweight steel structure concrete precast floor beam connection structure to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0006] The present invention is an energy-saving and lightweight steel structure concrete precast floor beam connection structure, including a precast beam and a floor slab. Six embedded steel bars are respectively penetrated and fixedly connected to the top of the precast beam, with two embedded steel bars set as a group. Six round holes are respectively opened at the top of the floor slab, and six clamping grooves are respectively opened at the bottom of the floor slab. The bottom end of the round hole is communicated with the top end of the clamping groove. It also includes a floor slab connection mechanism. The floor slab connection mechanism includes a sleeve slidably connected to the outer wall of the top end of the embedded steel bar. A cross plate is fixedly connected between adjacent two sleeves. One end of the cross plate penetrates the sleeve and is fixedly connected to one side of the inner wall of the sleeve. A bearing plate is fixedly connected to the top of the cross plate. The outer wall of the top end of the bearing plate is arranged between two floor slabs, and a stability component is arranged at the bottom of the cross plate.

[0007] Further, the stability component includes a square groove opened at the bottom of the cross plate. Two sliders are respectively slidably connected to both ends of the inner wall of the square groove. A first spring is fixedly connected between the two sliders. A rotating plate is rotatably connected to the bottom of the slider. One end of the rotating plate away from the slider is rotatably connected to a concave shell.

[0008] Further, there are three concave-shaped shells. A connecting block is fixedly connected to the side of the slider away from the first spring, and an arc-shaped frame is fixedly connected to the end of the connecting block away from the slider.

[0009] Further, a reinforcement assembly is provided on the side wall of the sleeve. The reinforcement assembly includes sliding rods that penetrate and are slidably connected to both ends of one side of the sleeve, and a semi-circular plate is fixedly connected to one end of the sliding rod.

[0010] Further, the semi-circular plate is arranged inside the sleeve. A second spring is fixedly connected to the side of the semi-circular plate close to the sliding rod, and one end of the second spring is fixedly connected to the inner wall of the sleeve.

[0011] Further, a semi-circular hole is opened on one side of the outer wall of the sleeve, and the outer wall of one end of the semi-circular plate is slidably connected to the inner wall of the semi-circular hole.

[0012] Further, an auxiliary assembly is provided on the side wall of the concave-shaped shell. The auxiliary assembly includes L-shaped rods fixedly connected to both sides of the concave-shaped shell. A conical extrusion plate is fixedly connected to the top of the end of the L-shaped rod away from the concave-shaped shell, and the top end of the conical extrusion plate penetrates through the bearing plate and extends into the inside of the bearing plate.

[0013] Further, the inside of the bearing plate is hollowed out. Sliding plates are respectively slidably connected to the inner walls on both sides of the bearing plate, and a return spring is slidably connected between the two sliding plates. The top end of the conical extrusion plate is arranged between the two sliding plates.

[0014] The present invention has the following beneficial effects:

[0015] (1). In the present invention, the round holes opened in the floor slab are docked with the top ends of the embedded steel bars. When the two floor slabs simultaneously fall along the outer wall of the embedded steel bars, the gravity generated by the floor slabs causes the sleeves on the outer wall of the embedded steel bars to move downward along the outer wall of the embedded steel bars. Through the cooperative docking of the embedded steel bars and the floor slabs, the rapid installation of the floor slabs and the precast beams on-site is realized. During this process, the sleeve will drive the cross plate to move downward. Because the cross plate is made of steel and has high strength and stiffness, when the two floor slabs fall to the top of the precast beam, the gravity generated by the two floor slabs will cause the center to shift from the center to the two ends. Through the rigid setting of the cross plate, it can prevent the bottom ends of two adjacent embedded steel bars from bending when the center of gravity of the floor slab shifts, improving the stability of the floor slab and the precast beam during installation and the finished product quality after installation.

[0016] (2) According to the present invention, when the horizontal plate moves downward, the horizontal plate drives the slider to move downward, the slider drives the rotating plate to move downward, the rotating plate drives the concave shell to move downward, and the concave shell will come into contact with the top of the precast beam during the downward movement of the concave shell, and will be reversely squeezed by the top of the precast beam, so that the rotating plate will rotate in a circle around the concave shell, and the rotating plate will drive the slider to slide along the inner wall of the square groove, the slider drives the connecting block to move, and the connecting block drives the arc frame to move, and the arc frame will come into contact with the side wall of the sleeve during the movement, thereby supporting and squeezing the two sleeves, further preventing the embedded steel bars of the sleeve from bending due to the center of gravity offset during the installation process, and improving the stability of the connection node between the floor slab and the precast beam.

[0017] (3) According to the present invention, when the arc frame moves, the arc frame will first contact the end of the sliding rod, so that the sliding rod slides inside the sleeve, and the sliding rod drives the semicircular plate to move. The semicircular plate slides along the inner wall of the semicircular hole and is limited by the positioning groove provided at the floor slab. When the semicircular plate moves to the inside of the positioning groove, the side wall of the semicircular plate will dock with the semicircular part of the inner wall of the positioning groove and squeeze the positioning groove, thereby supporting the two floor slabs, reducing the gravity that deviates to the two ends when the floor slab is installed, and improving the stability during installation. In addition, due to the setting of the bearing plate, the bearing plate is always between the two floor slabs when the floor slab and the prefabricated beam are quickly installed, and can resist the gap between the two floor slabs, further preventing the center of gravity of the two floor slabs from moving downward to the bottom of both sides.

[0018] (4) According to the present invention, when the concave shell contacts the top of the precast beam, the concave shell and the cross plate gradually approach each other, the concave shell is fixedly connected to the L-shaped rod, and the L-shaped rod is fixedly connected to the conical extrusion plate, so that the cross plate drives the bearing plate to move downward. During the downward movement of the bearing plate, the conical extrusion plate indirectly connected to the concave shell enters the interior of the bearing plate, and the conical top end of the conical extrusion plate contacts the two sliding plates sliding on the inner wall of the bearing plate, so that the two sliding plates move away from each other. During the movement of the sliding plate, the sliding plate contacts the side wall of the floor slab, further resisting the two floor slabs, further maintaining the center of gravity of the two floor slabs on the top of the precast beam, and improving the installation stability of the floor slab and the precast beam. After the installation is completed, the precast beam and the floor slab are grouted through the gap between the two floor slabs.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Example 1, please refer to Figure 1 - Figure 8 As shown in the figure, the present invention is an energy-saving and lightweight steel structure concrete precast floor beam connection structure, including a precast beam 1 and a floor slab 2. The precast beam 1 is made of fly ash lightweight building materials, and the floor slab 2 is made of energy-saving clay bricks of energy-saving blocks. Six embedded steel bars 3 penetrate and are fixedly connected to the top of the precast beam 1 respectively. Two embedded steel bars 3 are set as a group. Six circular holes 4 are respectively opened at the top of the floor slab 2, and six clamping grooves 5 are respectively opened at the bottom of the floor slab 2. The bottom end of the circular hole 4 is communicated with the top end of the clamping groove 5. It also includes;

[0033] A floor slab connecting mechanism 6. The floor slab connecting mechanism 6 includes a sleeve 61 slidably connected to the outer wall of the top end of the embedded steel bar 3, which docks the circular hole 4 opened at the floor slab 2 with the top end of the embedded steel bar 3. When two floor slabs 2 fall along the outer wall of the embedded steel bar 3 at the same time, the gravity generated by the floor slab 2 causes the sleeve 61 on the outer wall of the embedded steel bar 3 to move down along the outer wall of the embedded steel bar 3. Through the cooperation and docking of the embedded steel bar 3 and the floor slab 2, the rapid installation of the floor slab 2 and the precast beam 1 on site is realized. A cross plate 62 is fixedly connected between two adjacent sleeves 61. One end of the cross plate 62 penetrates the sleeve 61 and is fixedly connected to one side of the inner wall of the sleeve 61. A bearing plate 63 is fixedly connected to the top of the cross plate 62. The outer wall of the top end of the bearing plate 63 is arranged between two floor slabs 2. The sleeve 61 will drive the cross plate 62 to move down. Because the cross plate 62 is made of steel and has high strength and stiffness, when two floor slabs 2 fall to the top of the precast beam 1, the gravity generated by the two floor slabs 2 will cause the center to shift from the center to the two ends. Through the rigid setting of the cross plate 62, it can prevent the bottom ends of two adjacent embedded steel bars 3 from bending when the center of gravity of the floor slab 2 shifts, improving the stability of the floor slab 2 and the precast beam 1 during installation and the quality of the finished product after installation. A stabilizing component 64 is arranged at the bottom of the cross plate 62.

[0034] The stabilizing component 64 includes a square groove 641 opened at the bottom of the cross plate 62. Two ends of the inner wall of the square groove 641 are respectively slidably connected with sliders 642. A first spring 643 is fixedly connected between the two sliders 642. The bottom of the slider 642 is rotatably connected with a rotating plate 644. One end of the rotating plate 644 away from the slider 642 is rotatably connected with a concave shell 645.

[0035] There are three concave shells 645. A connecting block 646 is fixedly connected to one side of the slider 642 away from the first spring 643. An arc frame 647 is fixedly connected to one end of the connecting block 646 away from the slider 642. When the horizontal plate 62 moves downward, the horizontal plate 62 drives the slider 642 to move downward, the slider 642 drives the rotating plate 644 to move downward, and the rotating plate 644 drives the concave shell 645 to move downward. During the downward movement of the concave shell 645, it will come into contact with the top of the precast beam 1 and be reversely squeezed by the top of the precast beam 1, so that the rotating plate 644 The rotating plate 644 drives the slider 642 to slide along the inner wall of the square groove 641 by rotating around the concave shell 645, and the slider 642 drives the connecting block 646 to move, and the connecting block 646 drives the arc frame 647 to move. The arc frame 647 will contact the side wall of the sleeve 61 during the movement, thereby supporting and squeezing the two sleeves 61, further preventing the embedded steel bars 3 set in the sleeve 61 from bending due to the center of gravity offset during the installation process, thereby improving the stability of the connection node between the floor slab 2 and the precast beam 1.

[0036] In Embodiment 2, a reinforcing assembly 65 is disposed on the side wall of the sleeve 61 . The reinforcing assembly 65 includes a sliding rod 651 penetrating through and slidably connected to both ends of one side of the sleeve 61 . A semicircular plate 652 is fixedly connected to one end of the sliding rod 651 .

[0037] The semicircular plate 652 is arranged inside the sleeve 61, and a second spring 653 is fixedly connected to one side of the semicircular plate 652 close to the sliding rod 651. One end of the second spring 653 is fixedly connected to the inner wall of the sleeve 61. Due to the setting of the bearing plate 63, the bearing plate 63 is always between the two floor slabs 2 when the floor slab 2 and the prefabricated beam 1 are quickly installed. It can resist the gap between the two floor slabs 2 and further prevent the center of gravity of the two floor slabs 2 from moving downward to the bottom of both sides.

[0038] A semicircular hole 654 is provided on one side of the outer wall of the sleeve 61, and the outer wall of one end of the semicircular plate 652 is slidably connected to the inner wall of the semicircular hole 654. When the arc frame 647 moves, the arc frame 647 will first contact the end of the sliding rod 651, so that the sliding rod 651 slides inside the sleeve 61, and the sliding rod 651 drives the semicircular plate 652 to move. The semicircular plate 652 slides along the inner wall of the semicircular hole 654 and is affected by the locking groove 5 provided on the floor 2. When the semicircular plate 652 moves to the inside of the locking groove 5, the side wall of the semicircular plate 652 will dock with the semicircular part of the inner wall of the locking groove 5, and squeeze the locking groove 5, thereby supporting the two floor slabs 2, reducing the gravity that deviates to both ends when the floor slab 2 is installed, and improving the stability during installation from the side.

[0039] The side wall of the concave shell 645 is provided with an auxiliary component 66. The auxiliary component 66 includes L-shaped rods 662 fixedly connected to both sides of the concave shell 645. The top of one end of the L-shaped rod 662 away from the concave shell 645 is fixedly connected with a conical extrusion plate 663. The top end of the conical extrusion plate 663 penetrates through the bearing plate 63 and extends into the interior of the bearing plate 63.

[0040] The interior of the bearing plate 63 is hollowed out. The inner walls of both sides of the bearing plate 63 are respectively slidably connected with sliding plates 664. A return spring 665 is slidably connected between the two sliding plates 664. The top end of the conical extrusion plate 663 is arranged between the two sliding plates 664. When the concave shell 645 comes into contact with the top of the precast beam 1, at this time, the concave shell 645 and the cross plate 62 gradually approach. The concave shell 645 is fixedly connected with the L-shaped rod 662, and the L-shaped rod 662 is fixedly connected with the conical extrusion plate 663, so that the cross plate 62 will drive the bearing plate 63 to move downward. During the downward movement of the bearing plate 63, the conical extrusion plate 663 indirectly connected to the concave shell 645 will enter the interior of the bearing plate 63. The conical top end of the conical extrusion plate 663 will come into contact with the two sliding plates 664 sliding on the inner wall of the bearing plate 63, causing the two sliding plates 664 to move away from each other. During the movement of the sliding plates 664, they will come into contact with the side wall of the floor slab 2, further resisting between the two floor slabs 2, and further keeping the centers of gravity of the two floor slabs 2 on the top of the precast beam 1, laterally improving the installation stability of the floor slab 2 and the precast beam 1. When the installation is completed, grouting and pouring work is carried out on the precast beam 1 and the floor slab 2 through the gap between the two floor slabs 2.

[0041] During use, the round holes 4 opened in the floor slab 2 are docked with the top ends of the embedded steel bars 3. When the two floor slabs 2 simultaneously fall along the outer wall of the embedded steel bar 3, the gravity generated by the floor slab 2 causes the sleeve 61 on the outer wall of the embedded steel bar 3 to move downward along the outer wall of the embedded steel bar 3. Through the cooperation and docking of the embedded steel bar 3 and the floor slab 2, the rapid installation of the floor slab 2 and the precast beam 1 on site is realized. During this process, the sleeve 61 will drive the cross plate 62 to move downward. Because the cross plate 62 is made of steel and has high strength and stiffness, when the two floor slabs 2 fall to the top of the precast beam 1, the gravity generated by the two floor slabs 2 will cause the center to shift from the center to both ends. Through the rigid setting of the cross plate 62, it can prevent the bottom ends of two adjacent embedded steel bars 3 from bending when the center of gravity of the floor slab 2 shifts, improving the stability of the floor slab 2 and the precast beam 1 during installation and improving the finished product quality after installation.

[0042] When the cross plate 62 moves downward, the cross plate 62 drives the slider 642 to move downward, the slider 642 drives the rotating plate 644 to move downward, and the rotating plate 644 drives the concave shell 645 to move downward. During the downward movement of the concave shell 645, it will come into contact with the top of the precast beam 1, and will be reversely squeezed by the top of the precast beam 1, so that the rotating plate 644 will rotate in a circle around the concave shell 645, and the rotating plate 644 drives the slider 642 to slide along the inner wall of the square groove 641, and the slider 642 drives the connecting block 646 to move, and the connecting block 646 drives the arc frame 647 to move. During the movement of the arc frame 647, it will come into contact with the side wall of the sleeve 61, thereby supporting and squeezing the two sleeves 61, further preventing the embedded steel bars 3 set in the sleeve 61 from bending due to the offset of the center of gravity during the installation process, thereby improving the stability of the connection node between the floor slab 2 and the precast beam 1.

[0043] When the arc frame 647 moves, the arc frame 647 will first contact the end of the sliding rod 651, so that the sliding rod 651 slides inside the sleeve 61, and the sliding rod 651 drives the semicircular plate 652 to move. The semicircular plate 652 slides along the inner wall of the semicircular hole 654 and is limited by the locking groove 5 opened at the floor slab 2. When the semicircular plate 652 moves to the inside of the locking groove 5, the side wall of the semicircular plate 652 will dock with the semicircular part of the inner wall of the locking groove 5 and squeeze the locking groove 5, thereby supporting the two floor slabs 2, reducing the gravity that deviates toward the two ends when the floor slab 2 is installed, and the side improves the stability during installation. In addition, due to the setting of the bearing plate 63, the bearing plate 63 is always between the two floor slabs 2 when the floor slab 2 and the precast beam 1 are quickly installed, and can resist the gap between the two floor slabs 2, further preventing the center of gravity of the two floor slabs 2 from moving downward to the bottom of both sides.

[0044] When the concave shell 645 comes into contact with the top of the precast beam 1, the concave shell 645 and the cross plate 62 gradually approach each other, and the concave shell 645 is fixedly connected to the L-shaped rod 662, and the L-shaped rod 662 is fixedly connected to the conical extrusion plate 663, so that the cross plate 62 will drive the bearing plate 63 to move downward. During the downward movement of the bearing plate 63, the conical extrusion plate 663 indirectly connected to the concave shell 645 will enter the interior of the bearing plate 63, and the conical top end of the conical extrusion plate 663 will come into contact with the two sliding plates 664 sliding on the inner wall of the bearing plate 63, so that the two sliding plates 664 move away from each other. During the movement of the sliding plate 664, it will come into contact with the side wall of the floor 2, further resisting the two floor slabs 2, further maintaining the center of gravity of the two floor slabs 2 on the top of the precast beam 1, and improving the installation stability of the floor slab 2 and the precast beam 1 from the side. After the installation is completed, the precast beam 1 and the floor slab 2 are grouted through the gap between the two floor slabs 2.
