Embodiment 1

[0021] The specific operation steps are as follows:

[0022] (a) Pass the pipeline 2 through the reserved cavity on the concrete floor 1 and fix it;

[0023] (b) Clamp the pipe 2 with two wooden formwork 5 close to the lower surface of the concrete floor 1, the through hole 8 coincides with the outer surface of the pipe 2, and then place two angle steel frames 3 on both sides of the wooden formwork 5 , turn the nut 7 to shorten the distance between the two angle steel frames 3, so that the two wooden templates 5 clamp the pipe 2, and use the friction between the wooden template 5 and the pipe 2 to make the wooden template 5 and the angle steel frame 3 will not slide;

[0024] (c) After the wooden formwork 5 is fixed, the fine stone concrete 6 is poured between the concrete floor 1 and the pipe 2. After the fine stone concrete 6 is solidified, the wooden formwork 5 and the angle steel frame 3 can be removed by loosening the nut 7 and Turnaround use.

Abstract

The invention relates to a cast-in-place concrete floor punching pipe seal template device and a using method. The device comprises angle steel frames (3), wooden templates (5) and a round steel pulling rod (4). The device is characterized in that the two angle steel frames (3) are oppositely arranged, two ends of the angle steel frames (3) are connected with each other through the round steel pulling rod (4), the wooden templates (5) are boards with semicircle notches, the two wooden templates (5) which are horizontally arranged in a butt joint mode are clamped between the two angle steel frames (3), the wooden templates (5) are clamped and fixed at the lower end of a concrete reserved hole through the angle steel frames (3), and the wooden templates can be disassembled to be used circularly after being used. The cast-in-place concrete floor punching pipe seal template device is simple in structure, convenient to install, applicable to seal cast concrete of pipes with different diameters, quick to disassemble and capable of being used circularly.

Description

technical field [0001] The invention relates to the application field of building formwork, in particular to a formwork device for sealing a perforated pipe of a cast-in-place concrete floor slab and a use method thereof. Background technique [0002] In the process of general industrial and civil construction, it is often encountered that reserved holes are set in the reinforced concrete floor slab to pass through various pipes. Especially for the pipes on the floor of the bathroom, it is difficult to set the lower formwork when the gaps in the reserved holes are blocked, which leads to the phenomenon of water seepage often due to poor concrete pouring, which affects the quality of the project. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cast-in-place concrete floor perforated pipe sealing formwork device and its use method. The device has a simple structure and is easy to install. It is suitable for seali...
