Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cantilever beams, and more particularly to a prestressed cantilever beam combined structure. BACKGROUND

[0002] A cantilever beam refers to a load-bearing beam structure extending outside the main structure. Since the cantilever beam needs to bear weight, the safety performance of the cantilever beam is very important.

[0003] Referring to the Chinese patent publication No. CN217000804U, the prior art discloses a cable-stayed prestressed cantilever beam combined structure for climbing frames. The existing technology uses a cable structure to achieve tensioning and fixing of the combined cantilever beam, providing better safety performance. The combined cantilever beam includes a mounting beam and a suspended beam, and the mounting beam and the suspended beam are connected and fixed by a connecting plate and a bolt and nut connecting piece.

[0004] However, the suspended beam in the above-mentioned prior art is very heavy when installed, so the suspended beam at the extension position is very inconvenient to install when combined with the mounting beam. Especially when the installation height of the suspended beam is very high, how to lift the suspended beam in the air to combine and fix the suspended beam and the mounting beam together is a technical problem that is inconvenient to install in actual installation. SUMMARY

[0005] In view of the technical problem of the prior art that the suspended beam is inconvenient to fix on the mounting beam in the air, the mounting beam is provided as a hollow structure in the present application, the cantilever beam is installed through the mounting beam, and the upper surface of the installed cantilever beam is flush with the upper surface of the mounting beam.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions:

[0007] A prestressed cantilever beam combined structure includes a base, a mounting beam and a cantilever beam. The mounting beam is fixed to the upper surface of the base. The mounting beam is a hollow structure. The cantilever beam passes through the mounting beam and extends from the end of the mounting beam for cantilever installation. The cantilever beam includes a combination part, a cantilever part and a panel. The combination part and the cantilever part are integrally formed. The panel is separately provided with the combination part and the cantilever part. The upper surface of the combination part is lower than the upper surface of the cantilever part. The part of the lower surface of the combination part close to the cantilever part is flush with the lower surface of the cantilever part and forms a compensation cavity with the inner wall of the mounting beam. The part of the lower surface of the combination part away from the cantilever part is lower than the lower surface of the cantilever part. The panel is installed inside the compensation cavity.

[0008] Through the technical scheme, the mounting beam is arranged as a hollow structure, the cantilever beam is installed through the mounting beam, and the upper surface of the installed cantilever beam is flush with the upper surface of the mounting beam. Thus, the cantilever beam can be directly installed on the base without being installed in the air. In order to make the upper surface of the installed cantilever beam flush with the upper surface of the mounting beam, the cantilever beam is arranged as a combination of a combination part, a cantilever part and a panel. The combination part and the cantilever part are integrally formed, and the panel is arranged separately. The upper surface of the combination part is lower than the upper surface of the cantilever part. The part of the lower surface of the combination part close to the cantilever part is flush with the lower surface of the cantilever part and forms a compensation cavity with the inner wall of the mounting beam. The part of the lower surface of the combination part away from the cantilever part is lower than the lower surface of the cantilever part. Thus, the integrally formed combination part and cantilever part are arranged as a Z-shaped structure, and the panel is installed in the compensation cavity.

[0009] Further, the mounting beam is provided with fixing blocks on two sides, and the fixing blocks are fixedly connected to the upper surface of the base.

[0010] Further, the upper surface of the mounting beam is provided with a through hole, the upper surface of the combination part is provided with a threaded hole, a bolt is arranged in the through hole, and the bolt is threadedly connected to the threaded hole through the through hole.

[0011] Through the technical scheme, when the bolt is rotated, the combination part can be pulled up, so that the upper surface of the cantilever beam is flush with the outer upper surface of the mounting beam.

[0012] Further, the application further comprises a cable assembly installed above the base for providing pre-stress to the cantilever part.

[0013] The cable assembly comprises a stand, a first cable, a second cable and a third cable. The stand is vertically fixed to the upper surface of the base or the mounting beam. One end of the first cable and the second cable is fixed to the top end of the stand, and the other end is fixed to two fixing blocks respectively. One end of the third cable is fixed to the top end of the stand, and the other end is fixed to the cantilever part.

[0014] The upper surface of the cantilever part is provided with a mounting port, and the end of the third cable is connected to the inside of the mounting port.

[0015] Through the technical scheme, the cable assembly is used to enhance the installation stability of the cantilever beam and improve the bearing capacity of the cantilever beam.

[0016] Further, the application further comprises a support assembly installed below the cantilever part.

[0017] The support assembly comprises a support inclined rod, one end of the support inclined rod is fixed to the overhanging part, and the other end of the support inclined rod is fixed to the base.

[0018] The support inclined rod and the overhanging part are provided with a plurality of vertical rods, one end of the vertical rod is fixed to the overhanging part, and the other end of the vertical rod is fixed to the support inclined rod.

[0019] Through the above technical scheme, the support assembly is used to enhance the installation stability of the overhanging beam and improve the bearing capacity of the overhanging beam.

[0020] The length of the part of the lower surface of the combined part close to the overhanging part flush with the lower surface of the overhanging part is greater than or equal to the length of the installation beam.

[0021] Through the above technical scheme, the combined beam can be installed by passing through the installation beam according to the size relationship.
