Background technique

At present, large and super-large cities are gradually entering the development stage of urban renewal. More and more buildings have actual needs for structural transformation, and the demolition of the original structural floor has become an important part of structural transformation. Normally, chain saws and blade saws are mainly used for mechanical demolition of structural floors. During the cutting and lifting process, the reliable fixing of the floor slab is very important. The traditional method mainly uses steel wire rope sets to fix it. The basic process is: 1) Open four holes in the corners of the floor in advance; Use the steel wire rope to tighten the force, so as to ensure that the floor is kept horizontal and does not overturn during the cutting and lifting process.

However, affected by site conditions, building type, lifting environment and other factors, the traditional floor fixing measures show some disadvantages and shortcomings in the process of use:

(1) The workload of dismantling is heavy, and the steel wire rope is prone to wear and tear, which has great potential safety hazards;

(2) After the concrete is pre-drilled, the concrete at the edge of the hole in contact with the steel wire rope is relatively loose, and it is easy to peel off under the extrusion force of the steel wire rope. Sudden increase, increasing the safety risk of lifting;

(3) For large-space, long-span, high-clearance buildings (such as grand theaters, gymnasiums, exhibition halls, etc.), in order to remove the horizontal structure on the top of such buildings, it is necessary to set up scaffolding under the floor as an operating platform. The installation and dismantling workload is heavy, which is not conducive to saving the construction period and cost; if the dismantling operation is only performed on the upper part of the floor slab, it is difficult for the steel wire rope to be wound out from the bottom of the floor slab, and the floor slab cannot be firmly fixed.

The fixing system of the utility model is mainly used for demolition of floor slabs in engineering demolition.

In the traditional method, before the floor slab is demolished, it is necessary to use steel wire ropes to wrap the floor slab, but the steel wire rope is easy to wear and tear. The sudden increase in tension brings potential safety hazards; and because of its soft nature, the floor being hoisted often spins or even overturns, and construction safety cannot be effectively guaranteed.

The fixing system of the present utility model adopts a penetrating method, through which the limit assembly 2 passes through the floor 4 to be removed, the limit assembly 2 provides horizontal limit for the floor 4 to be removed, and the floor slab to be removed is passed through the limit rod 202 at the bottom of the limit assembly 2 4 Provide vertical support, and fix the floor with multi-point horizontal and vertical limit, with good fixing effect and high safety factor.

Considering that the fixing system of the present utility model is used at the engineering construction site, and the working environment is relatively harsh, the fixing system also needs to bear a large force. The support frame 1 and the limit assembly 2 are preferably made of steel structure, which can be high-strength steel or ultra-high-strength steel. The steel structure is strong and durable, and can ensure sufficient strength to avoid safety accidents due to structural damage during lifting.

The selection of the truss structure of the support frame 1 can be reasonably selected according to the shape and center of gravity of the floor 4 to be removed. For example, a plane truss is used for a flat floor, but a three-dimensional truss can be used for a thicker plane to increase the structural strength; For floors with uneven or irregular surfaces, the support frame 1 can adopt a heterogeneous structure to balance the stress on the installation points of the limiting components 2 .

Preferably in this embodiment, the support frame 1 includes two second lateral supports 102 and a first lateral support 101, and the two second lateral supports 102 are respectively installed at both ends of the first lateral support 101, and the first lateral support 101 It forms an I-shaped truss with the two second transverse supports 102; two suspension rings 104 are respectively provided on the two second transverse supports 102.

The centers of gravity of the two coincide vertically. Four lifting rings 104 are installed on the support frame 1, which coincide with the center of gravity of the two. A better stability can be ensured in the process.

The limit assembly 2 adopted in this embodiment also includes a fixed shaft 203 passing through the floor 4 to be removed. The fixed shaft 203 provides horizontal limit for the floor 4 to be removed and transmits vertical tension.
