Description

Technical Field

[0001] This application relates to the technical field of fish-belly beams, and in particular to a high-strength prestressed fish-belly beam. Background Technology

[0002] Prestressing is a compressive stress applied to a structure during construction to improve its service performance. During service, the prestressed compressive stress can completely or partially offset the tensile stress caused by the load, thus preventing structural failure. A fish-belly beam is a type of beam designed to increase bending strength and save materials.

[0003] The existing components include a waist beam, straight web members, diagonal web members, connecting rods, and steel strands. The straight web members are vertically connected to the waist beam, and the diagonal web members are fixedly connected to the waist beam and the straight web members. The connecting rods are vertically fixedly connected to two adjacent straight web members, and the connecting rods are located at the end of the straight web members away from the waist beam. The steel strands are located at the end of the straight web members away from the waist beam, and the steel strands are fixedly connected to two adjacent straight web members. During use, the various components are welded together to complete the fabrication of the entire fish-belly beam.

[0004] Regarding the aforementioned technologies, the inventors believe that when connecting the various components of the fish-belly beam, it is necessary to use hoisting equipment to lift the components and weld them while they are being lifted, which is inconvenient for workers to carry out the construction. Summary of the Invention

[0005] To address the drawback of inconvenience for construction workers, this application provides a high-strength prestressed fish-belly beam.

[0006] This application provides a high-strength prestressed fish-belly beam, which adopts the following technical solution: it includes a waist beam, straight web members and diagonal web members, and a first connecting component is provided between the straight web members and the waist beam for connecting them; the two ends of the diagonal web members are provided with second connecting components for connecting the diagonal web members to the waist beam and the straight web members respectively.

[0007] By adopting the above technical solution, when installing the fish belly beam, the first connector is used to connect the straight web members to the waist beam to determine the distance between adjacent straight web members. After connecting the straight web members to the waist beam, the second connector is used to connect the two ends of the diagonal web members to the waist beam and the straight web members respectively. This makes it easier for workers to connect the waist beam, straight web members and diagonal web members, thereby achieving the effect of facilitating the construction work.

[0008] Preferably, the first connecting assembly includes a sleeve, a plug-in sleeve, and a connecting bolt. The plug-in sleeve is perpendicularly and fixedly connected to the sleeve, and the center line of the plug-in sleeve in the length direction is perpendicular to the center line of the sleeve in the length direction. The sleeve is fitted onto the outer wall of the waist beam in the circumferential direction and is fixedly connected to the waist beam. The straight web member is slidably inserted into the plug-in sleeve. The connecting bolt is inserted into the plug-in sleeve and threadedly connected to the straight web member.

[0009] By adopting the above technical solution, when connecting the straight web member to the waist beam using the first connector, the sleeve is fitted onto the outer circumferential wall of the waist beam. At this time, the inner circumferential wall of the sleeve abuts against the outer circumferential wall of the waist beam. Then, the straight web member is inserted into the insertion sleeve, and the straight web member is connected to the insertion sleeve using connecting bolts. At this time, the workers do not need to lift the straight web member continuously, which achieves the effect of facilitating the workers' construction.

[0010] Preferably, the second connecting assembly includes a connecting plate and a limiting rod. The connecting plate is fixedly connected to the waist beam and the straight web member respectively, and the limiting rod is fixedly connected to the connecting plate perpendicularly. The inclined web member has a limiting hole. The limiting rod is slidably inserted into the limiting hole.

[0011] By adopting the above technical solution, when using the second connecting assembly to connect the two ends of the diagonal web member to the waist beam and the straight web member respectively, the connecting plate is first connected to the waist beam and the straight web member respectively. After the connection is completed, the limiting rod is fixedly connected to the connecting plate. After the connection is completed, the diagonal web member is lifted. At this time, the limiting rod is slidably inserted into the limiting hole. It is no longer necessary to lift the diagonal web member continuously. At this time, the workers weld the diagonal web member to the straight web member and the waist beam.

[0012] Preferably, the limiting rod has insertion holes on both symmetrical side walls; a snap-fit ​​block and a snap-fit ​​spring are provided in the insertion holes, the snap-fit ​​spring is fixedly connected to the limiting rod and the snap-fit ​​block, and the snap-fit ​​block is slidably inserted into the insertion hole.

[0013] By adopting the above technical solution, when the limiting rod is inserted into the limiting hole, the locking block compresses the locking spring. At this time, the locking block slides into the insertion hole. When the diagonal web rod abuts against the connecting plate, the locking block resets under the action of the locking spring, thereby fixing the position between the diagonal web rod and the connecting plate.

[0014] Preferably, the sleeve has a welding hole on the side wall near the straight web member; the insert sleeve has a through hole on its upper surface; the through hole communicates with the welding hole.

[0015] By adopting the above technical solution, after connecting the straight web member to the waist beam using the first connector, the welding tool is passed through the through hole and the welding hole to achieve the effect of welding the straight web member to the waist beam.

[0016] Preferably, the connecting plate is fixedly connected to a limiting guide plate, the limiting guide plate is located on the same side as the limiting rod, and the limiting guide plate gradually tilts away from the limiting rod from the end closer to the connecting plate to the end farther away from the connecting plate.

[0017] By adopting the above technical solution, the workers can lift the inclined web rod and align the limiting hole with the limiting rod. At this time, the setting of the limiting guide plate can facilitate the workers to align the limiting hole with the limiting rod, thus achieving the effect of facilitating the workers' construction.

[0018] Preferably, the upper surface of the snap-fit ​​block gradually slopes downward from the end closest to the snap-fit ​​spring to the end furthest from the snap-fit ​​spring.

[0019] By adopting the above technical solution, when the limiting rod is inserted into the limiting hole, the inclined surface of the locking block can guide the locking block. Under the gravity of the inclined web rod, the locking block automatically retracts into the insertion slot. When the inclined web rod abuts against the connecting plate, the locking block is reset under the action of the locking spring.

[0020] Preferably, a limiting block is provided inside the insertion tube, and the limiting block is slidably inserted into the straight web rod.

[0021] By adopting the above technical solution, the setting of the limiting block improves the connection stability between the straight web rod and the plug-in cylinder, while also making it easier for staff to use.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The design of the first and second connecting components facilitates the assembly of the fish-belly beam by the workers, achieving the effect of making it convenient for workers to use; 2. The use of snap-fit ​​blocks and snap-fit ​​springs in conjunction with the second connecting assembly improves the connection stability between the connecting plate and the diagonal web member, while also improving the connection stability between the diagonal web member and the waist beam; 3. The inclusion of through holes and welding holes facilitates welding of the straight web members to the waist beam, thereby improving the connection stability between the straight web members and the waist beam.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] This application discloses a high-strength prestressed fish-belly beam.

[0027] refer to Figure 1 The high-strength prestressed fish-belly beam includes a waist beam 1, straight web members 2, and diagonal web members 3. The waist beam 1, straight web members 2, and diagonal web members 3 are all made of H-beams. The straight web members 2 are perpendicular to the waist beam 1, and a first connecting component 4 is provided between the straight web members 2 and the waist beam 1 to connect the straight web members 2 and the waist beam 1. The two ends of the diagonal web members 3 are connected to the waist beam 1 and the straight web members 2, respectively, and a second connecting component 5 is provided between the diagonal web members 3 and the waist beam 1 and the straight web members 2.

[0028] refer to Figure 1 and Figure 2 The first connecting component 4 includes a sleeve 41, a plug-in sleeve 42, and a connecting bolt 43. Both the plug-in sleeve 42 and the sleeve 41 are rectangular cylindrical structures. The sleeve 41 is fitted onto the outer wall of the waist beam 1 and is fixedly connected to the waist beam 1. The center line of the sleeve 41 in the length direction is perpendicular to the center line of the plug-in sleeve 42 in the length direction. The straight web rod 2 is slidably inserted into the sleeve 41. The connecting bolt 43 passes through the plug-in sleeve 42 and is threadedly connected to the straight web rod 2. A welding hole 21 is opened on the side wall of the sleeve 41 near the straight web rod 2. A through hole 421 is opened on the upper surface of the plug-in sleeve 42 and communicates with the welding hole 21. A limiting block 8 is provided inside the plug-in sleeve 42 and is slidably inserted into the straight web rod 2.

[0029] refer to Figure 1 and Figure 2 When connecting the waist beam 1 and the straight web member 2 using the first connecting component 4, firstly, the sleeve 41 is fitted onto the outer wall of the waist beam 1, at which point the limiting block 8 is inserted into the waist beam 1. Then, the sleeve 41 is fixedly connected to the waist beam 1, which can be done by welding or by using bolts. Next, the straight web member 2 is inserted into the sleeve 41, and then the connecting bolt 43 is used to connect the straight web member 2 to the insertion hole 521. After the connection is completed, the workers use welding equipment to weld the straight web member 2 to the waist beam 1 through the through hole 421 and the welding hole 21. After the welding is completed, the connection between the straight web member 2 and the waist beam 1 is completed, thereby achieving the effect of facilitating the construction work of the workers.

[0030] refer to Figure 3 and Figure 4The second connecting component 5 includes a connecting plate 51 and a limiting rod 52. The connecting plate 51 is fixedly connected to the waist beam 1 and the straight web member 2 respectively. The limiting rod 52 is fixedly connected to the connecting plate 51 perpendicularly, and multiple limiting rods 52 are located on the same side of the connecting plate 51. The inclined web member 3 has a limiting hole 31, and the limiting rod 52 is slidably inserted into the limiting hole 31. The two symmetrical side walls of the end of the limiting rod 52 away from the connecting plate 51 have insertion holes 521. The insertion holes 521 are provided with a locking block 6 and a locking spring 61. The locking spring 61 is fixedly connected to the limiting rod 52 and the locking block 6, and the locking block 6 is slidably inserted into the insertion hole 521. The upper surface of the locking block 6 gradually slopes downward from the end near the locking spring 61 to the end away from the locking spring 61.

[0031] refer to Figure 3 and Figure 4 When using the second connecting component 5 to connect the diagonal web member 3 to the straight web member 2 and the waist beam 1 respectively, workers only need to use hoisting equipment to hoist the diagonal web member 3. At this time, ensure that the limiting hole 31 is aligned with the limiting rod 52. After the limiting rod 52 is inserted into the limiting hole 31, the diagonal web member 3 abuts against the locking block 6. Under the guiding action of the side wall of the locking block 6, the locking spring 61 is compressed, and the locking block 6 retracts into the insertion hole 521. When the diagonal web member 3 abuts against the connecting plate 51, the locking block 6 is reset under the action of the locking spring 61. At this time, the side wall of the locking block 6 near the diagonal web member 3 abuts against the side wall of the diagonal web member 3 near the locking block 6, thus realizing the use of the second connecting component 5 and connecting the diagonal web member 3 to the waist beam 1 and the straight web member 2; achieving the effect of facilitating construction by workers.

[0032] refer to Figure 1 and Figure 3 The connecting plate 51 is connected to the side wall of the limiting rod 52 and is fixedly connected to the limiting guide plate 7. The limiting guide plate 7 gradually tilts away from the limiting rod 52 from the end near the connecting plate 51 to the end away from the connecting plate 51. Before the limiting rod 52 is inserted into the limiting hole 31, it is necessary to ensure that the limiting hole 31 is aligned with the limiting rod 52. The setting of the limiting guide plate 7 can limit the inclined web rod 3, thereby reducing the swaying of the inclined web rod 3 in the lifting state, thus achieving the effect of facilitating the use of the staff.

[0033] The implementation principle of a high-strength prestressed fish-belly beam according to an embodiment of this application is as follows: the setting of the first connecting component 4 and the second connecting component 5 makes it easy for workers to connect the waist beam 1, the straight web member 2 and the diagonal web member 3, and then weld the three in pairs. At the same time, the setting of the snap-fit ​​spring 61 and the snap-fit ​​block 6 improves the connection stability between the second connecting component 5 and the diagonal web member 3, thereby improving the stability of the fish-belly beam, and also has the effect of facilitating the construction of workers.

[0034] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
