technical field

The invention relates to the technical field of building construction, in particular to a hanger for overall hoisting of pipelines and a construction method thereof.

Background technique

The overall hoisting of pipelines is one of the common construction projects in the field of construction. In the process of pipeline hoisting construction, there are not only great risks, but also a lot of manpower and material resources. It takes a lot of construction time during the construction process, so in the project During the construction process, a separate special construction plan should be prepared for the overall hoisting of the pipeline, which can only be implemented after being approved by the technical person in charge. It can be seen from the above that the overall hoisting of the pipeline occupies a very important position in the construction.

The existing overall hoisting of pipelines mostly uses hangers for hoisting, but the existing hangers have problems such as high risk factor and low construction efficiency in the construction process.

The steel plate is provided with bolt holes for the expansion bolts of the pipeline support to pass through, and the pipeline support is fixed on the concrete floor through the expansion bolts of the pipeline support.

The upper end of the pipe support angle steel of the pipe support has an upper round hole with a diameter of 20 mm, and the inverted chain is fixed on the pipe support through the upper round hole.

The lower end of the pipe support angle steel of the pipe support is provided with a lower round hole for connecting with the cross arm, and the diameter of the lower round hole is 10 mm.

The cross-arm is made of double channel steel, and a cross-arm angle steel is respectively welded at both ends of the cross-arm, and a circular hole with a diameter of 10 mm is opened on the cross-arm angle steel.

The size of the cross-arm angle steel is 125×125×12 mm.

A construction method for a hanger used for overall hoisting of pipelines, the method comprising the following steps:

Step 1, fixing the pipe support on the concrete floor with expansion bolts of the pipe support;

Step 2, fix the pipe to be hoisted on the cross arm, and connect the inverted chain to the pipe bracket and the cross arm;

Step 3: Hoist the four diagonal chains at the same time, and hoist the pipe to the position of the pipe support;

Step 4: Lock the cross arm and the pipe support with bolts, and then perform full welding between the pipe support and the cross arm. After the welding is completed, loosen the chain and fix the pipe.

In step 4, the bolts are fixed through the lower round holes of the pipe support and the round holes on the cross-arm angle steels at both ends of the cross-arm.

After the hoisting is completed, add a stabilizing device between the middle of the cross arm and the concrete floor.

The stabilizing device is composed of round steel, thick steel plate and stabilizing device angle steel. The lower end of the round steel is fixed in the middle of the cross arm, and the upper end is fixed on the stabilizing device angle steel. The stabilizing device expansion bolt fixes the thick steel plate and the stabilizing device angle steel on the concrete floor. .

The positive effects of the present invention are as follows:

The hanger of the present invention has the characteristics of simple structure, reasonable structure, and high safety factor. After the pipeline is lifted to the correct position by using the inverted chain, the crossarm and the pipeline support are temporarily locked and fixed by bolts, and then welded, and the crossarm It is fixed with the pipe support, and then the chain can be loosened and removed to fix the pipe. The whole method is simple and light, easy to use, and saves time and effort. After the installation is completed, a stabilizing device is installed between the cross arm and the concrete floor. , ensuring the stability of the whole structure, using the construction method of the hanger of the present invention to carry out construction can not only ensure the safety of construction, but also greatly improve the construction efficiency.

Detailed ways

The following examples are further detailed descriptions of the present invention.

For the embodiment, refer to the accompanying drawings 1-6. For the installation of horizontal pipelines, first draw a comprehensive pipeline support diagram, install the pipeline support as required, and drill a 20 mm diameter round hole on the column of the pipeline support in advance for Fixed chain. The cross arm of the pipe support is not welded to the column for the time being. First, connect the four prefabricated pipes together on the basement floor, and then hoist the four diagonal chains at the same time. The cross arm of the bracket is locked with the column, and then the welder performs full welding on the bracket. After the welding is completed, the chain is released to fix the pipeline. After the pipeline is fixed, a stabilizing device can be added between the middle of the cross arm and the concrete floor. The stabilizing device is composed of round steel, thick steel plate and angle steel. The lower end of the round steel is fixed in the middle of the cross arm, and the upper end is fixed on the angle steel. Fix the thick steel plate and angle iron to the concrete floor slab. In this way, the stabilizing device can disperse the weight of the pipeline borne by the pipeline support, thereby reducing the burden of the pipeline support and improving safety.

Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes, modifications and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. and modifications, the scope of the invention is defined by the appended claims and their equivalents.
