Description

Assembled formwork-free channel structure

Technical Field

The utility model belongs to the field of water distribution channel construction, and particularly relates to an assembled formwork-free channel structure.

Background

Various water distribution channels are common components of water treatment structures. According to the characteristics of various water treatment process flows, the water distribution channel is often arranged at the upper part or the middle part of the tank body, so that the working condition that a closed space is formed at the lower part of the channel is often caused. In the construction of the conventional method, in order to take out the templates and the scaffolds for supporting the channels, holes with proper sizes (usually not less than 1.0x1.80m) are reserved at the positions of the side walls, which do not affect the main structure, and after the channel strength reaches the design strength, the templates and the scaffolds in the closed space are taken out; and finally, blocking the hole by adopting bricks, and then performing construction of plastering, waterproofing and other procedures. It can be seen that the conventional method is complicated in procedure and has a secondary structure quality risk.

Detailed Description

The present utility model will be described in detail with reference to the accompanying drawings.

As shown in fig. 1-5, an assembled formwork-free channel structure comprises a concrete pool wall 1, a concrete pool wall 2, a water distribution channel 10 and a channel bottom die 5, wherein the channel bottom die 5 is connected with two opposite surfaces of the concrete pool wall 1, the water distribution channel 10 is cast on the channel bottom die 5, and the concrete pool wall 2 is cast on the concrete pool wall 1.

The post-cast concrete pool wall 2 and the channel 10 are integrally cast.

The channel bottom die 5 is a precast reinforced concrete slab, the channel bottom die 5 is provided with distributed steel bars 51 and stressed steel bars 52 which are criss-cross, and the stressed steel bars 52 extend out of two ends of the channel bottom die 5 and are connected with the horizontal steel bars 8 of the first poured concrete pool wall 1. And the bottom die 5 of the channel is provided with a hanging ring 11, so that the hanging is convenient.

When the assembly type channel bottom die 5 is prefabricated, the distribution steel bars 51, the stress steel bars 52 and the hanging rings 11 can be configured according to working conditions.

The cross section of the channel bottom die 5 is trapezoid with narrow upper part and wide lower part, so that the later-stage cement paste is convenient to joint, and the construction quality is improved.

A vertical water stop steel plate 6 is arranged between the first pouring concrete pool wall 1 and the second pouring concrete pool wall 2, and the water stop steel plates 6 are positioned at two ends of the channel bottom die 5.
