Description

Technical Field

[0001] This utility model relates to the field of steel reinforcement cage mechanisms, and in particular to a tree branch-shaped steel reinforcement cage structure for elevator pits. Background Technology

[0002] With the vigorous promotion of seismic isolation construction technology and the construction needs of some civil defense projects, the seismic isolation construction of the foundation beams in elevator shafts has become very important. To ensure the effectiveness of the seismic isolation layer and to ensure that the inter-story drift angle between adjacent seismic isolation layers does not exceed the prescribed limit under rare earthquake conditions, placing the elevator shaft and the outer contour of the main structure on the same standard floor would result in a rigid floor slab, thus affecting the translational effect of the seismic isolation layer. Therefore, the seismic isolation layer in the elevator shaft area needs to be set separately to ensure that the seismic isolation function can be effectively achieved in the seismic isolation structure, especially in the case of an elevator shaft below a basement, while meeting the requirements of safety and practicality.

[0003] When constructing the steel reinforcement framework for the elevator pit, multiple sets of steel reinforcement columns are typically used to support the foundation steel reinforcement layer, thereby ensuring the stability of the foundation steel reinforcement layer during construction. The steel reinforcement column is usually composed of four vertical steel bars tied together. In order to ensure the waterproof performance of the elevator pit, a waterproof membrane is laid at the bottom of the elevator pit. However, during construction, the bottom of the vertically constructed steel reinforcement columns may puncture and damage the waterproof membrane, thus affecting the waterproof performance of the elevator pit.

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] This utility model provides, for example Figure 1-3 The diagram shows a tree-branch-shaped steel reinforcement frame structure for an elevator pit. Example 1

[0041] The structure includes a waterproof membrane 1, a foundation steel reinforcement layer 2, a cantilever beam steel reinforcement group 4, and a supporting steel reinforcement group 3. The waterproof membrane 1 is used to waterproof the elevator pit. The foundation steel reinforcement layer 2 is laid on top of the waterproof membrane 1. The cantilever beam steel reinforcement group 4 is set on top of the foundation steel reinforcement layer 2. The supporting steel reinforcement group 3 is set between the cantilever beam steel reinforcement group 4 and the foundation steel reinforcement layer 2. The supporting steel reinforcement group 3 includes column groups 31, forked support members 32, and restraint components 33. The column groups 31 are set on top of the waterproof membrane 1. The tops of multiple column groups 31 are connected to the cantilever beam steel reinforcement group 4. The forked support members 32 are tied to the bottom of the column groups 31. The forked support members 32 are used to support the column groups 31. Under the action of the forked support members 32, the column groups 31 can be prevented from crushing the waterproof membrane 1. The restraint components 33 are set on the outside of the column groups 31. The restraint components 33 can ensure the stability of the multiple column groups 31 supporting the cantilever beam steel reinforcement group 4.

[0042] Specifically, the column assembly 31 includes steel bars 311 and steel hoops 312. The steel bars 311 are vertically installed on the top of the waterproof membrane 1. The top of the outer wall of the steel bars 311 is tied to the cantilever beam steel bar assembly 4. Multiple steel hoops 312 are tied to the outside of the four steel bars 311. The multiple steel hoops 312 can ensure the stability of the four steel bars 311.

[0043] In particular, the forked support member 32 includes an arc portion 321 and a horizontal portion 322. The arc portion 321 is tied to the reinforcing bar 311 and the reinforcing bar hoop 312. The horizontal portion 322 is connected to the end of the arc portion 321 and is located on the top of the waterproof membrane 1. Thus, the bottom of the horizontal portion 322 is in contact with the waterproof membrane 1 and will not damage the waterproof membrane 1. Furthermore, since the column assembly 31 is supported by the horizontal portion 322 of the forked support member 32, the bottom of the column assembly 31 can be in a floating state, thereby preventing the column assembly 31 from damaging the waterproof membrane 1.

[0044] Furthermore, the restraint assembly 33 includes a restraint steel bar ring 331, which is sleeved on the outside of the column assembly 31 and tied to the steel bar rod 311. Multiple restraint steel bar rings 331 can ensure the stability of the binding of multiple column assemblies 31. The restraint assembly 33 also includes a first diagonal fork steel bar 332 and a second diagonal fork steel bar 333. The first diagonal fork steel bar 332 is tied to one side of the restraint steel bar ring 331 in an X shape, and the second diagonal fork steel bar 333 is tied to the side of the restraint steel bar ring 331 in an X shape. The first diagonal fork steel bar 332 and the second diagonal fork steel bar 333 can restrain multiple restraint steel bar rings 331, thereby ensuring the stability of the binding of multiple restraint steel bar rings 331 to the column assembly 31.

[0045] Furthermore, the foundation reinforcement layer 2 includes foundation horizontal reinforcement 21 and foundation longitudinal reinforcement 22. The foundation horizontal reinforcement 21 is laid side by side on the top of the waterproof membrane 1, and the forked support 32 is located between adjacent foundation horizontal reinforcement 21. The foundation longitudinal reinforcement 22 and foundation horizontal reinforcement 21 are cross-connected vertically, and the bottom of the forked support 32 is connected to the intersecting foundation longitudinal reinforcement 22 and foundation horizontal reinforcement 21, thereby ensuring the stability of the forked support 32.

[0046] Specifically, the cantilever beam reinforcement group 4 includes crossbeam reinforcement and crossbeam reinforcement rings. The crossbeam reinforcement is arranged in a rectangular shape, and the crossbeam reinforcement rings are tied to the outside of the crossbeam reinforcement. That is, the cantilever beam reinforcement group 4 is formed by binding multiple crossbeam reinforcements and multiple crossbeam reinforcement rings together. Example

[0047] Based on Embodiment 1, it also includes diagonal bracing bars 5 and load-bearing bracing bars 6. The diagonal bracing bars 5 are in an inclined state and are tied to the column assembly 31 and the restraint assembly 33. The end of the load-bearing bracing bars 6 is tied to the column assembly 31 and the bottom of the cantilever beam reinforcement assembly 4. Multiple diagonal bracing bars 5 can further improve the stability of the column assembly 31. The diagonal bracing bars 5 can be designed with different inclination angles according to the construction requirements. The bottom of the diagonal bracing bars 5 is bent. Multiple load-bearing bracing bars 6 can improve the stability of the binding between the column assembly 31 and the cantilever beam reinforcement assembly 4.
