Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit engineering, in particular to a steel cage support bracket for a foundation pit construction site. Background Art

[0002] The main function of the steel cage is the same as that of the longitudinal steel bars of the column, mainly playing a tensile role. The compressive strength of concrete is high but the tensile strength is very low. It plays a role in restraining the pile body concrete so that it can bear a certain axial tension.

[0003] In foundation pit engineering, the steel cage is one of the important engineering structures. At the construction site, the steel cage is generally supported by a special bracket and is ready for use at any time. The main problem of the existing brackets is that it is very inconvenient to take the steel cage on and off the bracket. Especially for large-volume steel cages, it requires the joint efforts of multiple people to take the steel cage off the bracket. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0024] Such as Figure 1-2As shown in the figure, the utility model provides a technical solution: a steel cage support bracket for a foundation pit construction site, which includes a support base 1. A groove 2 is formed on the support base 1. A rotatable lead screw 3 is installed in the groove 2. It should be noted that the lead screw 3 is located below the conveying roller 8 and does not interfere with each other. The lead screw 3 is driven by an external first motor 4. Two groups of brackets 5 that slide in opposite directions are installed in a threaded fit between the lead screws 3. An anti-slip pad 6 is arranged inside the brackets 5. The anti-slip pad 6 is used to support the steel cage and serves the purpose of anti-slip.

[0025] As Figure 3 shown, a rotatable conveying roller 8 is installed in the middle of the support base 1. The two ends of the conveying roller 8 are wide and the middle is narrow to form an arc-shaped slope, which matches the arc surface of the steel cage, so as to be able to convey the steel cage more stably. The conveying roller 8 is driven by an external second motor 9. The conveying roller 8 is located below the bracket 5 and does not interfere with the bracket 5.

[0026] As Figure 1-2 shown, an auxiliary support assembly is arranged on the top of the bracket 5. The auxiliary support assembly includes a cylinder 10, and a rotatable auxiliary support wheel 11 is installed at the free end of the cylinder 10.

[0027] As Figure 4 shown, a travel wheel 13 with adjustable height is arranged at the bottom of the support base 1. A lifting groove 12 is formed at the bottom of the support base 1. The travel wheel 13 that can be lifted is installed in the lifting groove 12. A bushing 14 is arranged at the top of the travel wheel 13. An adjusting bolt 7 is installed in a threaded manner at the top of the support base 1. The end of the adjusting bolt 7 is movably connected to the bushing 14. In order to adapt to terrains with different slopes, we can adjust the height of the travel wheel 13 separately, so that the support base 1 can be kept in a horizontal state as much as possible, avoiding the shaking of the steel cage caused by uneven ground. By rotating the adjusting bolt 7, the travel wheel 13 is driven to move up and down, so that the support base 1 maintains a relatively horizontal state.

[0028] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0029] During use, the left and right sides of the steel cage (labeled a in the figure) are supported by two groups of brackets 5 on the top of the support base 1. In order to further ensure the stability of the steel cage on the brackets 5, the surface of the steel cage is tightened by the auxiliary support wheels 11 on both sides of the top of the brackets 5, so as to prevent the steel cage from slipping off the brackets 5.

[0030] When it is necessary to remove the steel reinforcement cage from the bracket 5, first turn on the first motor 4 to drive the screw rod 3 to rotate, thereby driving the two groups of brackets 5 to separate from each other, thus releasing the restraint on the steel reinforcement cage. The steel reinforcement cage falls onto the conveying roller 8 under its own weight. Then turn on the second motor 9 to drive the conveying roller 8 to rotate, so as to unload the steel reinforcement cage. During the unloading process, in order to prevent the steel reinforcement cage from shaking, it can be supported and limited by the auxiliary support wheel 11 to ensure smooth unloading.

[0031] In summary, for the steel reinforcement cage support bracket at the foundation pit construction site, by setting a slidable bracket structure, when the two groups of brackets are closed, the steel reinforcement cage can be supported, and the steel reinforcement cage is limited by the auxiliary support component, so that the steel reinforcement cage is steadily placed on the bracket. When the two groups of brackets are separated, the steel reinforcement cage automatically descends to the conveying roller below, and the steel reinforcement cage is unloaded from the bracket through the conveying roller, thus greatly facilitating the loading and unloading of the steel reinforcement cage.

[0032] It should be noted that the electrical components mentioned in this article are all electrically connected to the external main controller and 220V or 380V mains electricity. And the main controller can be a conventional known device such as a computer that plays a control role. Its control principle, internal structure, control switch method, etc. are all conventional means of the existing technology and are directly cited here without further elaboration.
