Abstract

The utility model discloses a steel-wood structural beam used for building an attic, which includes channel steel and wooden squares, and the wooden square part is embedded in the groove of the channel steel; the utility model has better load-bearing capacity and can be directly placed Lay the floor on the beam or hang the ceiling directly under the beam.

Description

Structural beams of steel and wood for the construction of the attic

technical field

The utility model relates to a steel-wood structural beam used for building a loft.

Background technique

As shown in Figure 1, Figure 2 and Figure 3, at present, there are two main types of beams used in building lofts for interior decoration, namely wooden beams and steel beams, each of which has its own advantages and benefits Inadequacies. Among them, the advantages of wooden beams are: the bottom plate can be directly laid on the beams or the ceiling can be suspended directly under the beams; but the disadvantage is: because the load-bearing capacity is not as good as that of steel beams, under the same conditions, the beam body specifications of wooden beams are relatively large . The advantages of steel beams are: good load-bearing capacity and relatively small beam size; its disadvantages are: because the beams are all made of steel, it is often necessary to install wooden bars or base boards before laying the floor or ceiling. The cost is higher and the project is more complicated.

Contents of the invention

The purpose of the utility model is to provide a steel-wood structural beam for building attics. The steel-wood structural beam has better load-bearing capacity, and the bottom plate can be directly laid on the beam or the ceiling can be suspended directly under the beam.

The technical scheme of the utility model is: a steel-wood structural beam for building an attic, including channel steel and wooden squares, and the wooden square part is embedded in the groove of the channel steel;

The wooden square is divided into an extended part and an embedded part, two symmetrical steps are formed between the extended part and the embedded part, the embedded part is embedded in the groove of the channel steel, and the steps are against the mating end surface of the channel steel;

The channel steel is provided with a fixing hole through which the locking member can realize the fixed connection between the channel steel and the wooden square; the fixing holes are arranged symmetrically on both side walls of the channel steel.

The utility model advantage is:

1. Compared with the original wooden beam, the utility model strengthens the strength of the beam, increases the load-bearing capacity of the beam, reduces the thickness dimension of the beam, and improves the space utilization rate.

2. Compared with the original steel beam, the utility model can directly lay the floor on the beam or hang the ceiling directly under the beam, which is stronger and has a longer service life than the way of setting wooden bars or base plates.

3. The utility model optimizes the structure, reduces the cost and improves the energy efficiency.

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Fig. 1 is the sectional view of wooden beam in the prior art;

Fig. 2 is the sectional view of channel steel in the prior art;

Fig. 3 is the sectional view of the I-shaped steel beam in the prior art;

Fig. 4 is a cross-sectional view of the utility model; (locking parts are not marked)

FIG. 5 is an exploded view of FIG. 4 .

Among them: 10 channel steel; 11 groove; 12 matching end face; 13 fixing hole; 20 wood square; 21 protruding part; 22 embedded part; 23 steps.

Detailed ways

Embodiment: as shown in Fig. 4 and Fig. 5, a kind of steel-wood structural beam that is used to build attic, comprises channel steel 10 and wood side 20, and wood side 20 is divided into protruding part 21 and embedded part 22, and protruding part Two symmetrical steps 23 are formed between 21 and the embedded part 22 , the embedded part 22 is embedded in the groove 11 of the channel steel 10 , and the steps 23 abut against the mating end surface 12 of the channel steel 10 .

The two side walls of the channel steel 10 are symmetrically provided with fixing holes 13 , and the locking member can realize the fixed connection of the channel steel 10 and the wooden square 20 through the fixing holes 13 .

Compared with the original wooden beam, the utility model strengthens the strength of the beam, increases the load-bearing capacity of the beam, reduces the thickness dimension of the beam, and improves the space utilization rate; compared with the original steel beam, the utility model has The base plate can be laid directly on the beam or the ceiling can be suspended directly under the beam, which is stronger and has a longer service life than the way of setting wooden bars or base plates.

The above are only specific application examples of the utility model, and do not constitute any limitation to the protection scope of the utility model. In addition to the above-mentioned embodiments, the utility model can also have other implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope of the utility model.
