Structural analysis of reinforced truss floor bearing plate

Steel truss is a very common material in our life. In practical use, its strength and stiffness are very good. Currently, it plays a very important role in the field of traditional architecture. In fact, a lot of people for its use performance and characteristics are not very understanding, this article for its advantages for a detailed introduction, I hope to read your choice or use help.

First, steel tube truss plays a very good role in supporting and building many building structures, especially for many large span building structures. Its use greatly increases the overall bearing capacity of the building and ensures the stability of the building.

Second, the appearance of steel pipe truss is not as rigid as traditional steel, so we can make a reasonable choice according to the style of the building in the construction, and integrate the color and style of the surrounding environment to design. At the same time, the long-term use will not cause any fading or deformation due to the change of the external environment, so it can be safely used.

1. Steel truss structure

The steel bar truss floor bearing plate combines the steel bar in the concrete plate with the construction formwork, forming a load-bearing member which can accept wet concrete dead weight and construction load in the construction stage of galvanized floor bearing plate, and acts as the lateral support of steel beam. In the service stage, the steel truss works with the concrete and receives the service load.

2. Use of data

(1) steel bar: the upper and lower strings are supplied by hot rolled steel bar HPB 235, HRB 400 or cold rolled ribbed steel bar 550; The belly rod is made of cold rolled round steel bar of 550 or 650 grades supplied by the plate. Hot rolled steel HPB 235 or HRB 335 for truss support reinforcement.

(2) Galvanized steel plate: 0.5mm thick galvanized steel plate is selected for the bottom die, and the amount of double-sided galvanized steel is 120~180gm/m.

(3) pin: in order to make concrete and steel beam can be effectively connected into all, in the steel beam is set up a pin, the use of special pin machine for construction.

3. Construction characteristics

Different from the previous construction method, the steel truss floor slab can be directly laid on the steel beam in the construction site, and then the concrete can be poured by simple steel engineering. The template does not need to erect wood mold and scaffolding, galvanized sheet at the bottom as a mold

Plate use, does not replace the stressed reinforcement, so there is no need to consider fire spraying and anti-corrosion protection and other problems, so the construction is convenient, can reduce the site reinforcement binding workload of about 70%, shorten the construction period and save money. In addition, the steel bars are evenly arranged, the distance between the upper and lower layers of steel bars and the thickness of concrete protective layer can be fully guaranteed, which creates favorable conditions for improving the construction quality of the floor slab.
