Description

Technical Field

[0001] The utility model relates to the technical field of building components, in particular to an assembled steel-wood building component. Background Art

[0002] Building formwork is a temporary building component used to shape concrete structures and components according to specified positions and geometric dimensions, maintain their correct positions, and bear the weight of the formwork and the loads acting on it. In the prior art, building formwork is generally made of metal and wood. Metal is heavy, expensive, and has high cost. Although wood is low in cost, it has poor strength and is easily damaged.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Embodiment 1:

[0031] See also Figure 1 -

[0032] Figure 4 , a prefabricated steel-wood building component, including a wooden template 1, such as Figure 2 As shown, four L-shaped steel frames 2 are respectively installed at the four corners of the wooden formwork 1, the edges of the L-shaped steel frames 2 are flush with the edges of the wooden formwork 1, and the square steels 4 are fixedly connected to the ends of the L-shaped steel frames 2. Specifically, the two ends of the L-shaped steel frames 2 are fixedly connected with the square steels 4 on the inner side. If the two square steels 4 are extended, they can form a rectangle with the L-shaped steel frames 2.

[0033] like Figure 2 As shown, connecting holes 3 are provided on the horizontal bars and the vertical bars of the L-shaped steel frame 2. The connecting holes 3 of two adjacent wooden templates 1 are corresponding. By passing the bolts through the two adjacent connecting holes 3, the two wooden templates 1 can be spliced ​​to form a larger template. This assembled splicing method is simple and efficient, and also ensures the strength of the overall structure.

[0034] In this embodiment, Figure 2 and Figure 3 As shown, a mounting hole 6 is formed through the square steel 4 on one side facing the wooden template 1 , and screws are passed through the mounting hole 6 and connected to the wooden template 1 , so that the entire square steel 4 and the L-shaped steel frame 2 can be fixed to the wooden template 1 .

[0035] Only installing the L-shaped steel frame 2 at the four corners of the wooden formwork 1 still cannot ensure the structural strength. Therefore, in this embodiment, a connecting piece is further provided between the two oppositely arranged square steels 4 to connect the two adjacently arranged L-shaped steel frames 2.

[0036] Specifically, Figure 3 and Figure 4As shown, the coupling member includes a threaded rod 7 and a nut 8. Two square steel bars 4 arranged opposite to each other are provided with through holes 5 along the direction of their virtual connecting line. The threaded rod 7 passes through the through holes 5 and is threadedly connected with the nut 8.

[0037] Thus, the threaded rod 7 can ensure the structural strength of the blank area between two adjacent L-shaped steel frames 2 on the wooden template 1. At the same time, since the nut 8 is adjustable on the threaded rod 7, it can also be applied to wooden templates 1 of different sizes.

[0038] In this embodiment, the four L-shaped steel frames 2 can be freely disassembled and installed on wooden templates 1 of other sizes, so as to facilitate the adjustment of the size of the template. When the size of the template is adjusted, the size of the entire enclosed space can also be changed, which is suitable for different usage environments.

[0039] like Figure 4 As shown, a cross reinforcement rib 9 is also provided on the wooden formwork 1 (it can be integrated with the wooden formwork 1 or installed on the wooden formwork 1 by bolts). Through holes 10 for the threaded rod 7 to pass through are provided at the four ends of the cross reinforcement rib 9. When the threaded rod 7 is installed, it also passes through the through hole 10, thereby being able to further ensure the structural strength.

[0040] Embodiment 2:

[0041] See also Figure 5 On the basis of the first embodiment, this embodiment provides another coupling member, specifically, the coupling member includes a sleeve 11 and an inner rod 12, two square steels 4 are arranged opposite to each other, one of which is fixedly connected to the sleeve 11, and the other is fixedly connected to the inner rod 12, and the inner rod 12 is movably inserted in the sleeve 11;

[0042] Therefore, by inserting the inner rod 12 in the sleeve 11 , the structural strength of the blank area between two adjacent L-shaped steel frames 2 can be ensured. At the same time, this structure can also adapt to the size of the wooden formwork 1 .

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
