Description

Technical Field

[0001] This application relates to the field of building structures, and particularly to an arc-shaped floor structure and a construction method thereof. Background Art

[0002] Arc-shaped floor structures are widely used in modern buildings, especially in large buildings such as shopping malls and office buildings. To meet the requirements of functionality and aesthetics, they are often designed as hollow buildings in shapes such as circles and ellipses. The hollow building is empty in the middle and surrounded by building bodies. And a floor is built at a certain height of the hollow building to block rainwater.

[0003] However, there is generally a problem in the design of the existing floor structures, that is, after a floor is set at a certain height of the hollow building, the natural lighting effect inside the building will be affected. Summary of the Invention

[0004] In order to improve the natural lighting effect inside the building, this application provides an arc-shaped floor structure and a construction method thereof.

[0005] An arc-shaped floor structure and a construction method thereof provided by this application adopt the following technical solutions: An arc-shaped floor structure includes a floor body. The floor body is provided with a light-transmitting opening. The floor body is gradually lowered from the position where the light-transmitting opening is located to the periphery and is arranged in an arc shape. A light-transmitting plate is fixedly installed inside the light-transmitting opening. A support ring frame is fixedly installed inside the floor body. A plurality of first steel beams and second steel beams are also fixedly installed inside the floor body. The support ring frame is arranged along the edge of the light-transmitting opening. The first steel beams and the second steel beams are bent to match the floor body. The first steel beams are horizontally arranged on both sides of the support ring frame. Both ends of the first steel beams are fixedly connected to the building body. The second steel beams are vertically arranged on both sides of the support ring frame. Both ends of the second steel beams are fixedly connected to the first steel beams nearby. The periphery of the support ring frame is connected to the first steel beams and the second steel beams nearby.

[0006] By adopting the above technical solutions, the design of the light-transmitting opening and the light-transmitting plate effectively solves the influence on the lighting of the middle part of the building after the floor is built. The combined use of the support ring frame, the first steel beams and the second steel beams ensures the stability and load-bearing capacity of the floor structure. At the same time, the fixed connection between the first steel beams and the building body and the nearby connection between the second steel beams and the first steel beams enhance the firmness of the overall structure.

[0007] Optionally, the first steel beam includes a plurality of sub-beams. Adjacent two sub-beams are welded to each other. A reinforcing plate is arranged between adjacent two sub-beams. The reinforcing plate abuts against the webs of adjacent two sub-beams. The reinforcing plate is provided with a plurality of rivets. Through holes for the rivets to pass through are opened on both the reinforcing plate and the webs of the sub-beams.

[0008] By adopting the above technical solution, the first steel beam is formed by connecting multiple sub-beams to each other, so as to facilitate the transportation of the sub-beams to the floor where the floor needs to be installed during construction. After adjacent sub-beams are connected by welding, reinforcement plates and riveting are used for connection, thereby improving the connection strength between adjacent two sub-beams.

[0009] Optionally, multiple said rivets are arranged at intervals in the height direction as a group, multiple groups of said rivets are arranged at intervals in the length direction of the sub-beam, each group of said rivets is provided with a support pipe, the bottom end of the support pipe is threadedly penetrated with a limiting rod, and a limiting groove for the limiting rod to penetrate is formed in the lower flange of the sub-beam, and the head of the rivet abuts against the support pipe.

[0010] By adopting the above technical solution, the support pipe can provide a stable supporting effect for the rivet, so that the construction personnel can more conveniently apply force to one end of the rivet away from the support pipe during the operation, causing it to deform to achieve the fixing effect.

[0011] Optionally, a driving block is fixedly installed at the head of the rivet, each said rivet is provided with a driving pipe, a driving groove for the driving block to slide is formed in the pipe wall of the driving pipe, the driving groove is inclined, a sliding port for the driving block to slide is formed in the support pipe, the sliding port is vertically arranged, the depth of the driving groove gradually increases from one end to the other end, the driving pipe is threadedly penetrated inside the support pipe, a driving rod is penetrated through the support pipe, the driving rod penetrates through each driving pipe inside the support pipe, a breakable rod is fixedly installed between the inner wall of the driving pipe and the driving rod, and an avoidance hole for the driving rod to penetrate is formed in the upper flange of the sub-beam.

[0012] By adopting the above technical solution, when the driving rod is rotated, the driving rod will drive the driving pipe to rotate, so that the driving block slides in the driving groove. Since the depth of the driving groove gradually increases from one end to the other end, the cooperation between the driving block and the driving groove can effectively adjust the force for the rivet to press the reinforcement plate. When the rivet presses the reinforcement plate to the predetermined strength, the breakable rod in the driving pipe is stressed and broken, thereby preventing the driving pipe from continuing to rotate and ensuring the stability and reliability of the riveting process.

[0013] Optionally, a rotating block is arranged at the top end of the driving rod, a clamping plate is fixedly installed on the bottom side of the rotating block, and a clamping groove for the clamping plate to enter is formed at the top end of the driving rod.

[0014] By adopting the above technical solution, the arrangement of the rotating block facilitates the operation of the driving rod. Through the cooperation between the clamping plate and the clamping groove, the detachable connection between the rotating block and the driving rod can be realized, which is convenient for the installation and disassembly of the driving rod during the construction process.

[0015] Optionally, a plurality of connecting beams are arranged on the circumferential side of the support ring frame. The beam body of the connecting beam is fixedly connected to the circumferential side of the support ring frame. One end of the connecting beam is fixedly connected to the beam body of the first connecting beam, and the other end of the connecting beam is fixedly connected to the beam body of the second steel beam.

[0016] By adopting the above technical solution, the arrangement of the connecting beam effectively enhances the structural stability between the support ring frame, the first steel beam and the second steel beam.

[0017] A construction method for an arc-shaped floor structure. The floor where the arc-shaped floor needs to be installed is the installation floor, including the following steps: According to the installation position of the first steel beam on the installation floor, connect the sub-beams at both ends of the first steel beam to the building body at the installation floor position; Weld the remaining sub-beams between the two sub-beams to form the first steel beam; Install the reinforcement plate and the rivets between two adjacent sub-beams; Connect the end of the second steel beam to the first steel beam nearby; Connect the circumferential side of the support ring frame to the surrounding first steel beam and the second steel beam nearby; Install a floor deck on the first steel beam and the second steel beam and pour concrete to form the floor body, and a light-transmitting opening is formed at the position where the support ring is located; Install a light-transmitting plate at the light-transmitting opening position.

[0018] By adopting the above technical solution, the setting of the light-transmitting plate is beneficial to improving the natural lighting effect inside the building.

[0019] Optionally, the next floor below the installation floor is the lower adjacent floor. When connecting the sub-beams at both ends of the first steel beam to the building body at the installation floor position according to the installation position of the first steel beam on the installation floor, install a disk buckle scaffold on the cantilever of the lower adjacent floor to support the sub-beams.

[0020] By adopting the above technical solution, installing a disk buckle scaffold at the cantilever part of the lower adjacent floor to support the sub-beams can effectively improve the structural stability of the sub-beams during the installation stage. This design can significantly reduce the risk of downward bending deformation of the sub-beams caused by gravity, thereby ensuring the overall construction quality and safety of the arc-shaped floor structure.

[0021] Optionally, the floor above the installation floor is the upper adjacent floor. For the sub-beams that exceed the cantilever length of the lower adjacent floor by two meters, use diagonal bracing to fix them to the building body of the upper adjacent floor.

[0022] By adopting the above technical solution, the sub-beam with a cantilever length of two meters beyond the lower adjacent layer can be firmly fixed. Specifically, by obliquely fixing the sub-beam to the building body of the upper adjacent layer, the structural stability of the sub-beam is effectively enhanced, preventing the risk of deformation or collapse caused by excessive cantilevering, thereby ensuring the overall safety and reliability of the curved floor structure.

[0023] Optionally, after the remaining sub-beams are welded between the two sub-beams to form a first steel beam, a support frame is built at the bottom of the building to support the first steel beam close to the support ring frame.

[0024] By adopting the above technical solution, additional support can be provided to the first steel beam after it is welded, especially for the first steel beam close to the support ring frame, which effectively enhances the overall stability of the floor structure. The construction of the support frame can disperse the load borne by the first steel beam and reduce the risk of deformation due to its own weight or construction load, thereby ensuring the safety and reliability of the curved floor structure during the construction process.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. By opening light-transmitting openings in the floor body and installing light-transmitting panels, the lighting problem in the hollow part of the building is effectively solved, ensuring that natural light can smoothly enter the interior of the building and improving the lighting conditions inside the building; 2. The floor body is designed in an arc shape, and cooperates with the supporting ring frame through the first steel beam and the second steel beam, thereby increasing the strength of the floor.

[0031] The floor body 1 is gradually lowered from the position where the light-transmitting opening 2 is located to the peripheral side and is arranged in an arc shape, so as to facilitate rainwater to fall into the floor body 1 and then drain out. At the same time, the curvature of the floor body 1 is also beneficial to improving the strength of the floor body 1, thereby reducing the situation where the floor body 1 bends downward when bearing heavy objects.

[0032] Referring to Figure 1 , Figure 2 , a support ring frame 4 is fixedly installed inside the floor body 1. The support ring frame 4 is arranged along the edge of the light-transmitting opening 2, and the support ring frame 4 is beneficial to forming the light-transmitting opening 2 by leaving a hole during the pouring of the floor body 1.

[0033] A plurality of first steel beams 5 and second steel beams 6 are also fixedly installed inside the floor body 1. The first steel beams 5 and the second steel beams 6 are arranged in a curved shape matching the floor body 1, thereby improving the overall strength of the floor body 1.

[0034] The first steel beams 5 are horizontally arranged on both sides of the support ring frame 4, and both ends of the first steel beams 5 are fixedly connected to the building body.

One end of the connecting beam 7 is fixedly connected to the beam body of the first connecting beam 7, and the other end of the connecting beam 7 is fixedly connected to the beam body of the second steel beam 6. The support ring frame 4 is fixed to the first steel beam 5 and the second steel beam 6 through the connecting beam 7, thereby facilitating the installation of the support ring frame 4.

[0036] Refer to Figure 3 , Figure 4 , the first steel beam 5 includes a plurality of sub-beams 51, and adjacent two sub-beams 51 are welded to each other. Two stiffening plates 8 are arranged between adjacent two sub-beams 51. The two stiffening plates 8 are clamped on the webs of adjacent two sub-beams 51. One stiffening plate 8 is provided with a plurality of rivets 9, and through holes 10 for the rivets 9 to pass through are formed in both the stiffening plate 8 and the web of the sub-beam 51.

[0037] The rivets 9 are sequentially passed through the stiffening plate 8, the web of the sub-beam 51 and the stiffening plate 8, and then heated and extruded to deform for fixation, thereby improving the connection strength between adjacent two sub-beams 51.

[0038] The second steel beam 6 has the same structure as the first steel beam 5, and is also reinforced by using the stiffening plate 8 and the rivet 9.

[0039] A construction method for an arc-shaped floor structure, which is applied to an arc-shaped floor structure in an embodiment of the present application. The floor where the arc-shaped floor needs to be installed is the installation floor, the next floor adjacent to the installation floor is the lower adjacent floor, and the upper floor adjacent to the installation floor is the upper adjacent floor.

[0040] It includes the following construction methods: Step S1: Connect the sub-beams 51 at both ends of the first steel beam 5 to the building body at the installation floor according to the installation position of the first steel beam 5 on the installation floor. And install a disk buckle scaffold on the cantilever of the lower adjacent floor to support the sub-beam 51, and use a cable stay to fix the sub-beam 51 whose length exceeding the cantilever length of the lower adjacent floor by two meters to the building body of the upper adjacent floor.

[0041] Step S2: Weld the remaining sub-beams 51 between the two sub-beams 51 to form the first steel beam 5 Step S3: Build a support frame at the bottom of the building to support the two first steel beams 5 close to the support ring frame 4.

[0046] Step S8: Install a light-transmitting plate 3 at the position of the light-transmitting opening 2.

[0047] The implementation principle of an arc-shaped floor structure and its construction method in an embodiment of this application is as follows: The design of the light-transmitting opening 2 and the light-transmitting plate 3 improves the lighting effect in the middle part of the building after the floor is built. At the same time, the first steel beam 5 and the second steel beam 6 are divided into multiple sections for installation, thereby reducing the difficulty of transporting the first steel beam 5 and the second steel beam 6 to the installation layer.

[0048] Embodiment 2 An embodiment of this application discloses an arc-shaped floor structure and its construction method.

[0049] Refer to Figure 5 、 Figure 6 The difference between an arc-shaped floor structure in an embodiment of this application and that in Embodiment 1 lies in that A plurality of rivets 9 are arranged at intervals in the height direction as a group, and multiple groups of rivets 9 are arranged at intervals in the length direction of the sub-beam 51. Each group of rivets 9 is provided with a support pipe 11, and the bottom end of the support pipe 11 is threadedly penetrated with a limiting rod 12. A limiting groove 13 for the limiting rod 12 to penetrate is formed in the lower flange of the sub-beam 51. Place the support pipe 11 between the upper flange and the lower flange of the sub-beam 51, and then rotate the limiting rod 12 to insert the limiting rod 12 into the limiting groove 13, so as to install the support pipe 11 between the upper flange and the lower flange of the sub-beam 51. Refer to Figure 6 、 Figure 7 A driving block 14 is fixedly installed at the head of the rivet 9, and each rivet 9 is provided with a driving pipe 15. A driving groove 16 for the driving block 14 to slide is formed in the pipe wall of the driving pipe 15, and the driving groove 16 is inclined. A sliding opening 17 for the driving block 14 to slide is formed in the support pipe 11, and the sliding opening 17 is vertically arranged. The depth of the driving groove 16 gradually increases from one end to the other end, and the driving pipe 15 is threadedly penetrated inside the support pipe 11. A driving rod 23 is penetrated through the support pipe 11, and the driving rod 23 penetrates through each driving pipe 15 inside the support pipe 11. An easily breakable rod 18 is fixedly installed between the inner wall of the driving pipe 15 and the driving rod 23, and an avoidance hole 19 for the driving rod 23 to penetrate is formed in the upper flange of the sub-beam 51.

[0050] A rotating block 20 is arranged at the top end of the driving rod 23, a clamping plate 21 is fixedly installed on the bottom side of the rotating block 20, and a clamping groove 22 for the clamping plate 21 to enter is formed at the top end of the driving rod 23.

[0051] The implementation principle of an arc-shaped floor structure and its construction method in the embodiments of this application is as follows: After two sub-beams 51 are welded to each other, two reinforcing plates 8 are placed on the webs of the sub-beams 51, and rivets 9 are used to pass through the through-holes 10.

[0052] After the rivets 9 pass through the through-holes 10, the support tubes 11 are placed between the upper and lower flanges of the sub-beams 51, and the driving blocks 14 on the rivets 9 are inserted into the driving grooves 16. Then, the limiting rod 12 is rotated so that the limiting rod 12 is inserted into the limiting groove 13, and the driving rod 23 passes through the avoidance hole 19.

[0053] After the driving rod 23 passes through the avoidance hole 19, the clamping plate 21 is inserted into the clamping groove 22, and then the driving rod 23 is rotated by driving the rotating block 20. The driving rod 23 drives the driving tube 15 to rotate, so that the driving block 14 slides inside the driving groove 16. Affected by the change in the depth of the driving groove 16, the rivets 9 are driven to press the reinforcing plates 8 against the webs of the sub-beams 51.

[0054] After the rivets 9 press the reinforcing plates 8 against the webs of the sub-beams 51, the breaking rods break, so that the driving rod 23 stops driving the driving tube 15 to rotate, which is beneficial to ensuring that each rivet 9 presses the reinforcing plate 8 against the web of the sub-beam 51.

[0055] The support tubes 11 support the rivets 9, which facilitates squeezing at one end of the rivets 9 away from the support tubes 11, and the rivets 9 are deformed and fixed in the through-holes 10.

[0056] The above are all the preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
