Problems solved by technology

[0002] Traditional hollow floor slabs often have quality defects such as poor seismic performance in engineering structures and poor overall performance after assembly, resulting in obvious cracks between the slabs, which not only seriously affect the use function, but also exist Security risks
[0003] Although there are two-way stress-bearing hollow slabs, they need to be core-pulled after pouring concrete to form a hollow, and the implementation of the operation is difficult

Embodiment Construction

[0030] Attached below Figure 1-7 The present invention is described in further detail: as Figure 1-2 As shown, a prefabricated hollow tube device for hollow floor, including hollow tube 1 and pipe sleeve 2; The connecting groove 10 connects the adjacent hollow pipes 1 through the connecting device 3 matched with the connecting groove; it also includes a sleeve 2 installed at the end of the hollow pipe for sealing the openings at both ends of the hollow pipe 1 .

[0031] Such as figure 2 , 5 As shown, the pipe sleeve 2 includes a pipe cover 20 and a stopper 21; the pipe cover 20 is sleeved on the end of the hollow pipe 1, and the stopper 21 is arranged at the lower part of the pipe cover 20, and is used for restricting the center when pouring concrete. Floating of the empty tube; the stopper 21 extends radially and horizontally along the tube cover 20, and is provided with a reserved hole 210 for the steel bar 211 to pass through, and the axial direction of the reserved h...

Abstract

The invention relates to a forming component of a hollow floor slab hole, in particular to a prefabricated hollow tube device for a hollow floor slab. The prefabricated hollow tube device for the hollow floor slab comprises hollow tubes, wherein the hollow tubes are placed in a longitudinal direction of the hollow floor slab, the interiors of the hollow tubes are hollow; connecting grooves are arranged at the two sides of the tube bodies, and the adjacent hollow tubes are connected by connecting devices matching with the connecting grooves. The prefabricated hollow tube device for the hollow floor slab provided by the invention has the following advantages: 1. The distance between the tubes of the prefabricated hollow tube group can be controlled according to the design requirements. 2. After being grouped by the connecting devices, the deviation of the hollow tubes caused by the vibration of a vibrating rod, the great or small distance between the adjacent hollow tubes can be avoidedwhen pouring the concrete. 3. The prefabricated hollow tube is conducive to realizing the flow prefabrication operation and improving the production efficiency. 4. The hollow floor slab can be pouredforced for once, and the hollow can be formed without pulling the core. 5. The anti-floating of the prefabricated hollow tube group can be achieved by penetrating a steel bar through the hole at the lower part of a sleeve tube.

Description

technical field [0001] The invention relates to a forming part of a hole in a hollow floor slab, in particular to a prefabricated hollow pipe device for a hollow floor slab. Background technique [0002] Traditional hollow floor slabs often have quality defects such as poor seismic performance in engineering structures and poor overall performance after assembly, resulting in obvious cracks between the slabs, which not only seriously affect the use function, but also exist Security risks. [0003] Although there are two-way force-bearing hollow floor slabs, they need to be core-pulled after pouring concrete, so as to form a hollow, and the implementation of the operation is difficult. Contents of the invention [0004] The purpose of the present invention is to solve the problems existing in the prior art, and provide a prefabricated hollow pipe device for the hollow floor which can improve the anti-seismic performance of the hollow floor and is easy to implement. [000...
