Description

Technical Field

[0001] The present application relates to the field of steel bar binding, and in particular to a steel bar binding frame for a standard layer of a caisson. Background Art

[0002] With the rapid development of gravity wharf construction, the requirements for caisson prefabrication have been continuously improved with the different construction conditions of the project. Today, caisson prefabrication is a key sub-item in gravity wharf construction, and the steel bar binding process has always been a key link in this sub-item construction. In the prior art, the traditional caisson prefabrication steel bar binding adopts the on-site binding process, that is, the semi-finished steel bars or mesh are transferred to the prefabricated pedestal for interlaced binding.

[0003] In recent years, with the increasing requirements for safety, quality and construction standardization, some hydraulic projects have adopted the process of standard layer steel bar overall binding and hoisting in the caisson layered prefabrication construction. This process changes the traditional on-site binding method, sets up a fixed standard layer steel bar prefabrication area for semi-factory construction, and uses a hoist to transfer the standard layer steel bar cage to the required position for height connection after it is prefabricated. The hoist is usually moved to the top of the caisson prefabricated standard layer through the hoisting equipment after the standard layer steel bar is tied, and then the prefabricated standard layer is installed on the hoist through the hoisting rope for hoisting.

[0004] With regard to the above-mentioned prior art, since the standard layer of steel bars takes up a large space after being tied, it is not convenient to quickly move the hoist to the position where the standard layer of steel bars are to be hoisted, and the work efficiency is low. Utility Model Content

[0005] In order to facilitate the rapid lifting of the standard layer of steel bars after binding and improve work efficiency, the present application provides a caisson standard layer steel bar binding cradle.

[0006] The present application provides a standard layer steel bar binding frame for caissons, which adopts the following technical solution:

[0007] A standard layer steel bar binding frame for a caisson includes a positioning base and a lifting frame, and also includes a bearing seat. The positioning base includes a bottom plate and a positioning frame. The positioning frame is fixedly installed on the top of the bottom plate. A plurality of positioning holes for positioning steel bars are opened on the top of the positioning frame. The bearing seat is arranged on the top of the bottom plate and is used for bearing. A plurality of positioning rods are fixedly connected to the top of the positioning frame. A fixing rod corresponding to the positions of the plurality of positioning rods is fixedly connected to the bottom of the lifting frame. The positioning rods and the fixing rods are fixed by bolts.

[0042] Continue to refer to Figure 2 and Figure 4In order to facilitate the application of force to realize the rotation of the rotating screw 16, the rotating screw 16 is coaxially fixedly connected with a rotating hand wheel 17, and the rotating hand wheel 17 is arranged near the top of the rotating screw 16. The positioning sleeve 12 is fixedly connected with a limiting plate 27, and the limiting plate 27 is located at the end of the rotating screw 16 away from the rotating hand wheel 17. The rotating screw 16 is rotated by applying force by the rotating hand wheel 17, so that when one end of the rotating rack 15 contacts the limiting plate 27, the two positioning plates 13 rotate to a horizontal state, so as to play a role in limiting the movement of the rotating rack 15, so as to facilitate the rapid rotation of the two positioning plates 13 to the position where the transverse reinforcement in the standard layer of steel bars is supported.

[0043] Reference Figure 1 and Figure 2 , the positioning frame 102 is provided with a plurality of installation areas formed by the cross beams 18 and the longitudinal beams 19. In the embodiment of the present application, the number of the cross beams 18 in the area surrounded by the positioning frame 102 is selected as three, and the number of the longitudinal beams 19 is selected as two, and the number of installation areas formed by the cross beams 18 and the longitudinal beams 19 is correspondingly twelve. The bearing seat 3 is provided with a plurality of installation areas corresponding to each other. Specifically, the bearing seat 3 includes a bearing mounting plate 301, a bearing plate 302, and a bearing lifting assembly. The bottom of the bearing mounting plate 301 is fixedly connected to four support columns 25 distributed in a rectangular shape, and each support column 25 is fixedly connected to the top of the bottom plate 101.

[0044] Reference Figure 3 and Figure 4 The load-bearing lifting assembly includes a load-bearing motor 20, a load-bearing screw 21 and a load-bearing guide rod 22, wherein the load-bearing motor 20 is horizontally fixedly installed on the top of the bottom plate 101 and located at the bottom of the load-bearing mounting plate 301, and a load-bearing worm 23 is fixedly installed at the output end of the load-bearing motor 20. The load-bearing screw 21 is vertically penetrated and rotatably matched with the load-bearing mounting plate 301, and a load-bearing worm wheel 24 meshing with the load-bearing worm 23 is coaxially fixedly connected to the outer peripheral surface of the load-bearing screw 21 near its bottom, so that the load-bearing motor 20 drives the load-bearing screw 21 to rotate through the cooperation of the load-bearing worm 23 and the load-bearing worm wheel 24, and the self-locking effect between the load-bearing worm 23 and the load-bearing worm wheel 24 is conducive to ensuring the stability of the position of the load-bearing screw 21 after rotation.

Each bearing guide rod 22 is vertically fixedly installed on the top of the bearing mounting plate 301, and each bearing guide rod 22 is penetrated and slidably matched with the bearing plate 302, so that when the bearing motor 20 drives the bearing screw 21 to rotate, the bearing plate 302 moves in the vertical direction due to the thread match with the bearing screw 21 and under the limiting action of the bearing guide rod 22, that is, it performs lifting and lowering movements, thereby facilitating the staff located on the top of the bearing plate 302 to realize the binding of standard layer steel bars at different heights, and the applicability is strong.

[0046] The implementation principle of the standard layer steel bar binding frame of a caisson in the embodiment of the present application is as follows: when binding the standard layer steel bars, the positioning holes 4 and the positioning columns 5 play a role in positioning the vertical bars in the standard layer steel bars, so as to ensure the stability of the position of the vertical bars when they are bound and fixed. The setting of the bearing seat 3 makes it easy for the staff to realize the binding between the horizontal bars and the vertical bars distributed along the length direction of the vertical bars. The cooperation of the positioning rod 7 and the fixing rod 10 facilitates ensuring the stability of the relative position of the positioning frame 102 and the lifting frame 2. When the standard layer of steel bars is tied, the standard layer of steel bars and the lifting frame 2 are hoisted and connected, and the direct fixation of the positioning rods 7 and the fixing rods 10 is released to realize the transportation of the standard layer of steel bars. After the standard layer of steel bars are transported, the lifting frame 2 is returned to its original position and the positioning rods 7 and the fixing rods 10 are fixed by bolts to facilitate the binding of the next standard layer of steel bars. When the lifting frame 2 is lifted back to its original position after the lifting is completed, the next standard layer of steel bars has not yet been tied and will not interfere with the lifting frame 2. Therefore, it is convenient to quickly move the lifting frame 2 to the position where it is connected to the positioning base 1, that is, the position where the standard layer of steel bars are hoisted, which is beneficial to improve the work efficiency of hoisting the standard layer of steel bars.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
