Description

Technical Field

[0001] The utility model relates to the technical field of roof truss parts, and specifically relates to a roof truss cross beam. Background Art

[0002] Traditional roof truss cross beams are usually made of a single material such as wood, steel, or concrete. Their structural forms are relatively simple, and their load-bearing capacities are limited, making it difficult to meet the requirements of modern buildings for high-strength and high-stability roof trusses. Therefore, it is necessary to newly design a roof truss cross beam to improve the overall stability and load-bearing capacity of the roof truss. Content of the Utility Model

[0003] Based on this, the purpose of the utility model is to provide a roof truss cross beam to solve the existing inconvenient technical problems.

[0004] To achieve the above purpose, the utility model provides the following technical solution: a roof truss cross beam, characterized in that it includes a cross beam and a connecting piece; the connecting piece is of a straight tube type; a partition is provided in the middle of the connecting piece; a plurality of fixing holes are provided on the connecting piece; a plurality of corresponding fixing holes two are provided on the cross beam; the cross beam and the connecting piece are connected by screwing bolts into the fixing holes and the fixing holes two.

[0005] Further, the cross beam is composed of a combined I-shaped steel and concrete, and the concrete is filled on both sides of the I-shaped steel to form a composite cross-sectional shape.

[0006] Further, a plurality of reinforcing ribs are provided on both sides of the I-shaped steel.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] The utility model is designed with a combined material, which gives full play to the advantages of different materials and improves the load-bearing capacity and stability of the cross beam.

[0009] The cross-sectional shape is optimized, enabling the cross beam to better disperse stress when stressed, and improving the overall stability of the roof truss.

[0010] The utility model connects the cross beam through the connecting piece, making the roof truss more firm and reliable.

[0011] The utility model has a simple structure, is easy to manufacture and install, and is applicable to various different types of buildings. Description of the Drawings

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0017] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0018] As Figures 1 to 3 A specific embodiment of a roof truss cross beam shown includes a cross beam 1 and a connecting piece 2; the connecting piece 2 is of a straight tube type; a partition board 3 is provided in the middle of the connecting piece 2. When connecting, the two cross beams 1 are pushed into the connecting piece 2 and abutted against the partition board 3, so that the second fixing hole 5 on the cross beam 1 and the fixing hole 4 of the connecting piece 2 can be corresponding, which is convenient for installation; a plurality of fixing holes 4 are opened on the connecting piece 2; a plurality of second fixing holes 5 corresponding to the fixing holes 4 are opened on the cross beam 1; the cross beam 1 and the connecting piece 2 are connected by screwing bolts 6 into the fixing holes 4 and the second fixing holes 5. The bolts 6 can pass through the fixing holes 4 of the connecting piece 2 and the second fixing holes 5 of the cross beam 1, thereby tightly connecting the two together.

[0019] Specifically, the cross beam 1 is composed of a combination of I-shaped steel 7 and concrete. The concrete is filled on both sides of the I-shaped steel 7 to form a composite cross-sectional shape. The steel provides strength and stiffness, while the concrete provides better load-bearing capacity and durability.

[0020] Specifically, a plurality of reinforcing ribs 8 are provided on both sides of the I-shaped steel 7. The reinforcing ribs 8 extend along both sides of the I-shaped steel 7 and are tightly connected to the steel; the reinforcing ribs 8 can effectively disperse and resist external forces, thereby enhancing the overall load-bearing capacity of the cross beam 1.

[0021] The orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of simplifying the description of the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the protected content of the present utility model.

[0022] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
