Problems solved by technology

In this regard, the most commonly used support method at present is the use of reinforced steel columns of section steel or reverse support of thick steel pipes, but neither of them can guarantee the reinforcement effect. The contact between the steel column and the concrete slab is not easy to ensure tightness, which affects the force effect of the reverse support.

Embodiment 1

[0053] like Figure 1-3 As shown, a reinforcement structure suitable for the basement roof of a construction elevator in this embodiment includes a scaffolding system 1 and a hard rubber buffer layer 2 . Among them, the scaffolding system 1 is arranged on the basement floor 3, and is specifically a bowl buckle type or socket type steel pipe scaffolding system. The upper end of the scaffolding system 1 is provided with a basement roof 4, and a construction elevator is provided above the basement roof 4. A hard rubber buffer layer 2 with a thickness of 30 mm is arranged at the junction between the lift foundation 5 of the construction lift and the basement roof 4 .

[0054] The scaffold system 1 specifically includes a steel pipe support pole 12 , a horizontal pole 13 and a scissor brace 14 , wherein the steel pipe support pole 12 constitutes the basic skeleton of the scaffold body 11 . Horizontal rods 13 are horizontally arranged between the steel pipe support rods 12, and spe...

Embodiment 2

[0065] A method for reinforcing the basement roof of a construction elevator in this embodiment includes the following specific steps:

[0066] (1) Determine the construction elevator and its installation location:

[0067] According to the requirements of vertical transport materials for high-rise buildings in the project, select the appropriate lifting equipment, that is, choose the SC200 / 200 dual-purpose construction elevator for people and goods; install the construction elevator on the basement roof 4, and set the guide rails near the structural columns;

[0068] (2) Determine the foundation of the lift:

[0069] According to the foundation size provided by the construction hoist manual and the actual situation on site, set up the hoist foundation 5 with a size of 5600㎜×4200㎜, a thickness of 330㎜, and a concrete strength grade of C30;

[0070] At the same time, in order to reduce the impact of the construction elevator on the floor, a layer of 30 mm thick rubber plate is...

Embodiment 3

[0088] A specific application of the reinforcement structure of the above-mentioned embodiment of this embodiment:

[0089] Apply the reinforced structure in the above-mentioned embodiment to the following projects respectively:

[0090] (1) Riverside Court 1 # 、4 # The building project is located at the intersection of Weiwu Road and Yingzhou Road, Changfeng County, Hefei City, with a total construction area of ​​31357m 2 , of which 1# building is a 28-story frame-shear structure with a total building height of 86.3 meters and a roof elevation of 81.2 meters. Building 4# is a 32-story frame-shear structure with a total building height of 97.9 meters and a roof elevation of 92.8 meters. . The roof of the outdoor basement is a cast-in-place hollow laminated floor slab with a thickness of 550mm and a clear basement height of 3.7m. According to the amount of masonry structure and decoration of high-rise residential buildings in this project, 2 sets of SC200 / 200 dual-purpose c...

Abstract

The invention provides a reinforcing structure suitable for a basement top plate of a construction elevator. The reinforcing structure comprises a scaffold system and a hard rubber buffer layer. The scaffold system is arranged on a basement bottom plate and is particularly a bowl buckle type or socket and spigot type steel pipe scaffold system, a basement top plate is arranged at the upper end ofthe scaffold system, and a construction elevator is arranged on the basement top plate. The hard rubber buffer layer is arranged between an elevator foundation and the basement top plate; the scaffoldsystem specifically comprises steel pipe supporting vertical rods, horizontal rods and diagonal braces, the horizontal rods are horizontally arranged between the vertical rods, and the diagonal braces are arranged on the periphery of the outer side and in the longitudinal direction and the transverse direction of the interior of the scaffold body. A top support and a bottom pad are respectively arranged at the top end and the bottom ends of the steel pipe supporting vertical rods. The invention further provides a reinforcing method for the basement top plate. According to the invention, a bowl buckle type or socket and spigot joint type scaffold system is adopted, and structures such as the top supports, bottom cushions and the keels are matched, so that stress transmission can be ensured, and a good basement top plate reinforcing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a reinforcement structure and a reinforcement method suitable for the basement roof of a construction elevator. Background technique [0002] With the development of cities and the development of underground space, large-scale urban complexes are gradually increasing, and underground garages are integrated with residential buildings. During the construction process, the construction hoist must be arranged on the basement roof. The dynamic load and impact load generated by the construction hoist will have an adverse effect on the basement roof structure, and may even cause cracking of the basement roof structure. Therefore, it is necessary to support the basement roof structure within the scope of the construction hoist foundation. In this regard, the most commonly used support method at present is the use of reinforced steel columns of section steel or reverse supp...
