Background technique

Purlin is a building material commonly used in roof construction. The two ends of the purlin are lapped on the beams or columns on both sides of the factory building. Strength, the use of solid web purlins requires thicker steel thickness, so it will lead to the problem of large steel consumption; and the use of lattice purlins plus support system will lead to complex construction and increase the support system. It will affect the space use of the factory building, and it will also lead to the problem of a large amount of steel.

The technical problem solved by the present invention is to provide a new type of self-stabilizing purlin assembly, which has strong structural strength and can be applied to the installation of purlins with large span and large purlin distance.

The technical solution adopted by the present invention to solve the technical problem is: the self-stabilizing purlin assembly includes three purlins arranged parallel to each other in a triangular distribution, and a plurality of connectors are arranged between any two purlins of the three purlins. The corresponding two purlins are fixedly connected by the connecting piece, and a three-dimensional space network structure is formed after connecting the three purlins through the connecting piece; the three purlins include two main purlins and an auxiliary purlin, and the auxiliary purlin is located between the two main purlins. Between the main purlins, the length of the main purlins is greater than that of the auxiliary purlins, and purlin overlapping parts are formed at the two ends of the main purlins relative to the ends of the auxiliary purlins.

Further, the distance between the auxiliary purlins and the two main purlins is equal.

Further, both the main purlin and the auxiliary purlin are steel pipes.

Further, the pipe diameters of the two main purlins are equal and larger than the pipe diameters of the auxiliary purlins.

Further, the pipe diameter of the auxiliary purlin is 0.5-0.8 times the pipe diameter of the main purlin.

Further, the connecting piece is a steel pipe, a steel bar or a section steel.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1 to 3, the self-stabilizing purlin assembly of the present invention includes three purlins arranged in parallel to each other in a triangular distribution, and a plurality of connecting parts 1 are arranged between any two purlins of the three purlins, Each connector 1 fixedly connects the corresponding two purlins, and forms a three-dimensional space network structure after connecting the three purlins through the connector 1; the three purlins include two main purlins 2 and one auxiliary purlin 3, the The auxiliary purlin 3 is located between two main purlins 2 , the length of the main purlin 2 is longer than that of the auxiliary purlin 3 , and a purlin lap 4 is formed at the two ends of the main purlin 2 relative to the ends of the auxiliary purlin 3 .

Among them, the reason why the three purlins are set is that the three purlins are connected by the corresponding connectors 1 to form a stable triangular structure, which ensures the stability of the structure when the amount of steel is relatively small, and can effectively improve the quality of the purlin assembly. Excellent bending resistance; the purlin assembly has strong self-stability during the hoisting process and after installation, and can effectively meet the installation requirements of purlins with large spans and large purlin distances.

In addition, the specific connection structure and distribution method of the connector 1 in the present invention can be referred to as shown in Figure 1, wherein the so-called connection of three purlins to form a three-dimensional space network structure is to ensure that the three purlins pass through the corresponding After the connectors 1 are connected, a skeleton structure with high structural strength and strong bending resistance can be formed. In the present invention, a relatively large number of connectors 1 are usually used for connection according to needs, so as to ensure that the purlin assembly can form a spatial network structure and the overall structural strength.

In addition, the connecting piece 1 in the present invention may specifically include a vertical piece 5 perpendicular to the length direction of the purlin, or an inclined piece 6 arranged obliquely relative to the length direction of the purlin, or may include both the vertical piece 5 and the inclined piece 6 . As shown in Figure 1, the vertical member 5 and the inclined member 6 are provided at the same time; and by setting multiple sets of connecting members 1 at intervals along the length direction of the purlin, the final structural strength of the purlin assembly can be improved. The number of sets and the quantity used for the connector 1 are specifically related to the length of the purlin, and can be set according to the actual situation.

In addition, the two main purlins 2 in the present invention need to install the purlin overlapping parts 4 at both ends of the main purlins 2 on the corresponding beams or columns of the workshop, so in order to avoid the interference of the auxiliary purlins 3, it is necessary to install two The length of the root main purlin 2 is longer than the length of the auxiliary purlin 3, as shown in Figure 1 and Figure 2, the part of the main purlin 2 relative to the auxiliary purlin 3 forms a purlin lap joint for lap joint installation Section 4 for easy installation of the entire purlin assembly.

More specifically, in order to ensure the structural symmetry of the entire purlin assembly, to ensure the structural strength of the purlin assembly; as shown in Figure 3, the present invention further sets the auxiliary purlins 3 to the two main purlins 2 respectively. The spacing is equal; that is, the three purlins are distributed in an isosceles triangle. More specifically, three purlins can be further arranged to be distributed in an equilateral triangle.

In addition, in order to reduce the steel consumption of the purlin assembly as much as possible, reduce the cost and its own weight, in the present invention, each purlin can be further set to be a steel pipe piece. More specifically, in the present invention, the pipe diameters of the two main purlins 2 can be further set to be equal and greater than the pipe diameter of the auxiliary purlin 3, because the two ends of the main purlin 2 need to be used as the purlin lap joint 4 for connection and installation, so The bearing load of the main purlin 2 is generally greater than the bearing load of the auxiliary purlin 3, so the use of a relatively thick steel pipe for the main purlin 2 can improve its strength; for example, the pipe diameter of the auxiliary purlin 3 can be set to 0.5 -0.8 times; in this way, the amount of steel used can be reduced as much as possible while ensuring the overall structural strength, thereby effectively reducing costs.

In addition, each connecting piece 1 in the present invention can be adopted as a steel pipe fitting, a steel bar or a section steel, and the two ends of each connecting piece 1 can be directly welded to the corresponding purlins respectively by welding. When the connecting piece 1 is a steel pipe, its pipe diameter should be smaller than the pipe diameter of the purlin, for example, the pipe diameter of the connecting piece 1 is set to be 0.2-0.5 times the pipe diameter of the auxiliary purlin 3 .

Without loss of generality, in the present invention, the wall thickness of each steel pipe can be set more realistically. Under the condition of ensuring the overall structural strength of the purlin assembly, steel pipes with relatively thin wall thickness should be used as much as possible to reduce the amount of steel used and save cost.
