Portable multifunctional irregular truss

Abstract

The invention relates to a truss which is used for exhibition field and is a portable multifunctional irregular truss for building a tabernacle. The portable multifunctional irregular truss is characterized by comprising a truss (1) and a joint (8); the truss (1) is a square steel tube; four arms of the square steel tube are respectively distributed with connection holes; the joint (8) consists of two parts which are connected by a movable shaft; and two ends of the joint (8) are inserted into two ends of two square steel tubes to be connected with the square steel tubes. The truss is stable and safe, is molded in one step, has simple process and light and portable volume, is convenient for conveying, takes small space, can be folded fast and has multiple functions.

Description

technical field [0001] The invention relates to a truss, which is used in the exhibition and display industry, and is a portable multifunctional special-shaped truss for building temporary houses. Background technique [0002] At present, the most commonly used structure of trusses used in industries such as exhibitions and celebrations is that four thin steel pipes are welded in parallel to the four corners of two round-shaped steel plates with a size of about 20x20cm to form a large cubic structure. There are round holes for connecting truss to truss with screws. This structure consists of orderly overlapping of many single trusses to form an orderly structure. [0003] However, there are many defects in existing trusses. Most of the truss structures weld steel into a square with a cross section of about 20*20cm, and a cube structure with a length of 20cm, 45cm, 60cm, 100cm, 200cm, 300cm, etc. Generally, the end face or near the end face There are small holes of fixed si...

Problems solved by technology

More manpower is needed in the construction process, which again increases the input cost

[0007] However, due to its large size and heavy weight, it is very inconvenient to store and keep, and often needs to occupy a large amount of warehouse space, which also makes the company invest a lot of money in the storage of trusses.

[0008] However, the shapes that these trusses can build are limited. Generally, they can only build a flat background gable, or a limited number of booth frame structures.

[0009] Therefore, there are problems in several existing booth frame structures: 1. Solder joint connection, easy to break; 2. Complicated manufacturing process; 3. Large volume, heavy weight, and difficult handling; 4. Large storage cost; 5. Disassembly and assembly Difficult, time-consuming and laborious to remove the screws; 6. The structure after construction is rigid and monotonous, and the flexibility of the shape is extremely poor; 7. Non-90-degree and 180-degree connections are often connected with iron wires, burying potential safety hazards; 8. When building special-shaped shapes, it takes two A large number of steel-wood structures that are difficult to reuse are produced at one time, which is a huge waste; 9. The aesthetics are extremely poor and the visual sense is cumbersome; 10. There is no functional ductility; 11. Due to structural defects, creative thinking is greatly limited

12. In addition, it is time-consuming and labor-intensive when using the existing method to directly stretch the painting screen; 13. There are many restrictions on the size of the truss, and it cannot be flexibly adapted to the on-site environment

14. Parallelogram structure, poor stability
