Problems solved by technology

[0004] The object of the present invention is to provide a modularized filling device and construction method for fireproof plugging in pipe casings without lifting molds. By placing the blanking casing and the lifting casing between the pipe and the floor casing, and using a cable tie to make the lifting The casing is lifted and lowered based on the lower material casing to adapt to different floor heights, and finally the fireproof material is blocked in the lower material casing and the lifting casing to realize the filling and fixing of the pipeline and the floor casing, which solves the problem of people's climbing Hanging formwork is used to seal the gap between the pipe and the floor casing, which brings about the risk of climbing operations and the problem of reduced work efficiency

Embodiment 1

[0039] like Figure 1-3 As shown in the figure, the present invention is a fire-proof blocking modular filling device in a mold-free pipeline casing, comprising a pipeline 1 and a floor casing 2, and a filling device 3 is fixedly installed between the pipeline 1 and the floor casing 2; the filling device 3 is used for Filled with fireproof material, which can be cement mortar or viscous fireproof mud;

[0040] The filling device 3 includes two half blanking sleeves 4, two semi-lifting sleeves 5 and a cable tie 6. The half blanking sleeve 4 is connected with the half lifting sleeve 5 through the cable tie 6; the half blanking sleeve 4 There is an extrusion tool 7 on it; the extrusion tool 7 is used to compact the fireproof material in the semi-cutting sleeve 4 and the semi-lifting sleeve 5, so as to improve the blocking quality of the fireproof material; The lifting sleeve 5 can be made of flame retardant PVC material;

[0041] The end face of the semi-cutting sleeve 4 has an...

Embodiment 2

[0056] The construction method of the fire-proof plugging modular filling device in the pipe casing without the lifting formwork comprises the following steps:

[0057] Step 1: penetrate and fix the floor casing 2 in the floor; pipe 1 penetrates the floor casing 2 and is fixedly installed on the wall; perform concentricity correction on the floor casing 2 and the pipe 1;

[0058] Step 2: Measure the thickness of the floor slab, and adjust the matching position of the cable tie 6 on the one-way bayonet 4041, so that the distance between the top surface of the semi-cutting sleeve 4 and the bottom surface of the semi-lifting sleeve 5 is equal to the thickness of the floor slab;

[0059] Step 3: Put the semi-cutting sleeve 4 and the semi-lifting sleeve 5 connected by the tie 6 into the gap between the floor sleeve 2 and the pipeline 1, and make the arc-shaped outer edge 402 overlap the floor sleeve. The top end face of the tube 2;

[0060] Step 4: Put the other half of the blanki...

Abstract

The invention discloses a formwork-hanging-free pipeline and casing interior fireproof blocking modular filling device and a construction method thereof, and relates to the technical field of fireproof engineering and pipelines. The formwork-hanging-free pipeline and casing interior fireproof blocking modular filling device comprises a pipeline and a floor casing, and a filling device body is fixedly mounted between the pipeline and the floor casing; the filling device body comprises two semi-feeding casings and two semi-lifting casings, and the semi-feeding casings are connected with the semi-lifting casings through ribbons; and an extrusion tool is arranged on one of the semi-feeding casings in a matched mode. A feeding casing and a lifting casing are placed between the pipeline and thefloor casing, the lifting casing ascends and descends based on the feeding casing through the ribbons so as to adapt to different floor slab thicknesses, finally, fireproof material blocking is conducted in the feeding casing and the lifting casing, and the pipeline and the floor casing are filled and fixed; and the structure is simple, operation is convenient, the risks of manual climbing and formwork hanging are avoided in the process, and the blocking efficiency and standardization of fireproof materials between the pipeline and the floor casing are improved.

Description

technical field [0001] The invention belongs to the technical field of fire protection engineering and pipelines, and in particular relates to a fire blocking modular filling device and a construction method in the casing of a free-formwork pipeline. Background technique [0002] Fire protection has become a necessary safety facility for high-rise buildings and an important means to ensure the safety of personal and property. In daily life, after the fire engineers install the pipes in the concrete floors and walls and correct the concentricity between the pipes and the floor casings, they need to use the flat formwork to be placed at the bottom of the floor casings to lift the formwork. Filling with fire blocking materials between the casing and the floor casing, and this kind of climbing hanging mold has the safety risk of high-altitude operation, and the working efficiency of the climbing hanging mold is low, which affects the progress of the entire fire protection projec...
