Description

Technical Field

[0001] The utility model relates to the field of cantilever concrete construction, in particular to an assembled cantilever I-beam top support device. Background Art

[0002] Concrete cantilever structures are often used in projects such as building skywalks, observation decks, stair platforms, and are widely used.

[0003] For the existing concrete cantilever structure construction, the construction method is mostly to use an oblique support mechanism in combination with welding or to use a pull rod. For projects with tight schedules and heavy tasks, the above methods are not feasible. For the installation of cantilevered horizontal I-beams, when welding is used, the position cannot be fine-tuned after the cantilever structure is welded, and it cannot be dismantled after the construction is completed. Especially for the horizontal support position, when the construction position is not accurate enough and needs to be forcibly dismantled, a large amount of material waste will be caused, and the heavy load will further increase the difficulty of dismantling, seriously consuming labor costs and delaying the construction period.

[0004] Therefore, a new type of assembled cantilevered I-beam top support device is needed to meet the usage requirements. Utility Model Content

[0007] Furthermore, the top connecting support mechanism includes a top support body, a support sleeve plate installed on the top support body, a support locking rod passing through the support body and the support sleeve plate, and a locking rod tooth plate connected to the support locking rod; the transverse I-beam is inserted into the top support body and locked by the support locking rod.

[0008] Furthermore, the top support body includes a transverse seat body that cooperates with the transverse I-beam and a seat body connecting part that cooperates with the oblique I-beam to be connected and installed. The transverse seat body as a whole has an open "rectangular" structure. The transverse I-beam is inserted in the transverse seat body and installed on the upper surface of the locking rod tooth plate.

[0009] Furthermore, there are four support sleeves, which are respectively installed on the four corners of the transverse seat body, and there are four support locking rods, which are respectively installed on the four support sleeves.

The assembled cantilever I-beam top support device of the technical solution can be adjusted according to different angles during construction through the top connecting support mechanism. The top support mechanism adopts an assembled structure for easy installation and removal, avoiding the defects of being non-removable and non-reusable after welding in traditional construction. After the I-beam is positioned and installed in cooperation with the positioning boot, it is then adjusted and locked in cooperation with the top component, and the overall structure is convenient and reliable to install.

[0022] In this embodiment, the top connection support mechanism includes a top support body 11, a support sleeve 14 which is mounted on the top support body, a support locking rod which is inserted through the support body and the support sleeve, and a locking rod tooth plate 15 which is connected to the support locking rod. The transverse I-beam is inserted into the top support body and locked by the support locking rod. The support sleeve 14 is provided with a plurality of the same structures, which are mounted on the support body 11 (welding can also be adopted). The support locking rod can be a screw structure. The lower end of the support locking rod is fixedly connected with the locking rod tooth plate 15. A raised tooth structure is provided on the upper surface of the locking rod tooth plate 15, so that after the I-beam is installed, the locking effect is better and the sliding along the length direction of the I-beam is avoided.

[0023] In this embodiment, the top support body includes a transverse seat body 12 for inserting with a transverse I-beam and a seat body connection part 13 for connecting and installing with an oblique I-beam. The transverse seat body 12 is a "rectangular parallelepiped" structure with an opening. The transverse I-beam is inserted into the transverse seat body and installed on the upper surface of the locking rod tooth plate 15. The transverse seat body 12 is a rectangular parallelepiped structure, and a strip slit is opened in the middle position to facilitate installation with the I-beam. The seat body connection part 13 is formed at the lower part of the transverse seat body 12 and has a positioning hole for installing with the I-beam positioning shoe 7. The two are adjusted to a suitable angle for positioning and locking.

[0024] In this embodiment, there are four support sleeves 14 and the four support sleeves 14 are respectively installed on the four corners of the transverse seat 12, and there are four support locking rods and the four support locking rods are respectively installed on the four support sleeves. There are four support sleeves 14, which are distributed on the four corners of the transverse seat 12. The support locking rod can be a locking screw. The bottom of the locking screw is fixedly connected to the locking rod tooth plate 15. When installing, the I-beam passes through the strip slit of the support sleeve 14 and is arranged on the upper surface of the four locking rod tooth plates 15. After adjusting to a suitable position, it can be locked.

[0025] In this embodiment, the locking rod tooth plate 15 is a rectangular structure, and the upper surface of the locking rod tooth plate is provided with a crisscross convex tooth structure. The locking rod tooth plate 15 is fixedly arranged at the lower end of the support locking rod, and its upper surface is provided with a staggered convex tooth structure, which is convenient for matching with the I-beam when installing, and has a stronger bite effect after tightening to prevent it from moving horizontally (i.e., in the length direction of the I-beam).

[0026] In this embodiment, the I-beam positioning shoe 7 includes a positioning shoe body, a lower shoe mounting portion 72 formed at the lower end of the positioning shoe body and connected to the base plate, and a positioning protrusion 71 mounted on the positioning shoe. The positioning shoe body is provided with an I-beam positioning groove 73 for inserting and installing the oblique I-beam. After the lower shoe mounting portion 72 is adjusted and installed in conjunction with the base plate support ear 81, it is positioned and locked in conjunction with the anti-loosening locking assembly 91. The oblique I-beam is inserted through the I-beam positioning groove 73. The positioning protrusion 71 provided on the positioning shoe body cooperates with the locking bolt to position and lock the oblique I-beam inserted into the I-beam positioning shoe 7. The positioning protrusion 71 can be set to be evenly distributed in multiple pieces to meet the connection strength.

[0027] In this embodiment, the positioning protrusion 71 is provided with a locking rod (either a common bolt or a screw rod) for positioning and locking with the oblique I-beam.
