Description

Technical Field

[0001] The present invention relates to the technical field of round bamboo arch roofs, and more specifically, to a round bamboo arch roof and a purlin installation method. Background Art

[0002] Bamboo is widely distributed in China. It has the characteristics of being renewable, having a fast growth cycle, strong carbon sequestration ability, and excellent mechanical properties. Therefore, bamboo is a green building material with good performance. As a building structural material, it can promote the green and low-carbon development of buildings. At present, the large-space requirements of venue construction are often achieved by connecting round bamboos vertically and horizontally and bundling them into round bamboo arches. However, round bamboo has problems such as being prone to splitting, corrosion, complex node connections, and immature calculation theories. Therefore, in large venues, round bamboo arches are mainly used to form a structural form with a relatively simple spatial relationship. For the complex spatial structure composed of round bamboo arches, since the upper surface of the round bamboo arch is not a plane, there is a position conflict between the installation of the roof purlins and the round bamboo arch. Moreover, due to the easy cracking of the round bamboo itself, the installation of a large number of purlins on the bamboo arch surface is complex and the installation efficiency is low. Summary of the Invention

[0031] The fixing member 1 is installed on the round bamboo arch 100, and the steel purlin support 2 is arranged on the fixing member 1 along the length direction of the round bamboo arch 100 and at the designed position of the purlin 200; the fixing member 1 is used for connecting and fixing the round bamboo arch 100 on one hand, and supporting and fixing the steel purlin support 2 on the other hand; the installation slot 211 is used for fixing the purlin 200; thus, the round bamboo arch 100 and the purlin 200 are fixedly connected, solving the position conflict of the connection of the space purlin 200, having good applicability, and enabling the installation of the purlin 200 of the complex space bamboo arch roof;

[0032] In the present invention, the fixing member 1 supports the steel purlin support 2, and the fixing member 1 functions as a rigid backing plate to disperse the concentrated load of the purlin support, reducing the risk of splitting caused by the concentrated load on the round bamboo arch 100.

[0033] In some possible implementation manners, in order to effectively realize the support and fixation of the steel purlin support 2 to the purlin 200;

[0034] The steel purlin support 2 includes a support column 21 having a columnar structure and installed on the fixing member 1; the installation slot 211 is arranged at the top of the support column 21.

[0035] It should be noted that the shape of the installation slot 211 can be set according to the shape of the purlin 200; when the cross-section of the purlin 200 is a square structure, the installation slot 211 will be a U-shaped structure;

[0036] In some possible implementation manners, the cross-section of the purlin 200 is circular, and at this time, the installation slot 211 is a C-shaped structure, and its opening is arranged on the side away from the fixing member 1.

[0037] In some possible implementation manners, in order to enable the support column 21 to be effectively installed on the arc-shaped steel plate 11;

[0038] The steel purlin support 2 further includes a reinforcing rib 22 arranged outside the support column 21 and having its bottom installed on the fixing member 1.

[0039] In some possible implementation manners, there are multiple groups of the reinforcing ribs 22 and they are uniformly arranged along the circumferential direction of the support column 21.

[0040] Preferably, there are three groups of the reinforcing ribs 22 arranged outside each support column 21, and each group of the reinforcing ribs 22 is installed on the arc-shaped steel plate 11 and connected to the outside of the support column 21; the reinforcing ribs 22 are uniformly arranged along the circumferential direction of the support column 21, and the included angle formed between two groups of the reinforcing ribs 22 is 120°.

[0041] In some possible embodiments, the fixing member 1 is installed on the round bamboo arch 100 and includes an arc-shaped steel plate 11 having an arc-shaped structure, and a connecting member 12 installed on the arc-shaped steel plate 11 and connected to the round bamboo arch 100; the curvature at the bottom of the arc-shaped steel plate 11 is the same as the curvature on the outer side of the round bamboo arch 100.

[0042] The arc-shaped steel plate 11 is installed on the round bamboo arch 100 and has the same curvature as that of the circular arch, so that the two can be effectively connected. The arc-shaped steel plate 11 is connected to the round bamboo arch 100 through the connecting member 12 to form an integral body, increasing the reliability and redundancy of the joint connection, enabling the steel purlin support 2 to transfer the load in three parts through the arc-shaped steel plate 11, and avoiding damage to the round bamboo arch 100 caused by concentrated load transfer.

[0043] In some possible embodiments, in order to effectively realize the connection between the arc-shaped steel plate 11 and the round bamboo arch 100;

[0044] The connecting member 12 includes a plurality of sets of bolt assemblies one 121 arranged along the length direction of the arc-shaped steel plate 11, and bolt assemblies two 122 arranged between adjacent two sets of bolt assemblies one 121.

[0045] In the prior art, the round bamboo arch 100 is formed by assembling multiple bamboo materials into an arch bridge structure; the bolt assemblies one 121 and the bolt assemblies one 121 are mainly used to fix the arc-shaped steel plate 11 to all the bamboo materials;

[0046] As Figure 2 shown, the round bamboo arch 100 is a structure with four groups arranged in parallel, each group including four bamboo materials, and the bolt assemblies one 121 and the bolt assemblies two 122 will fix the four groups of structures respectively.

[0048] As Figure 2 shown, both the bolt one and the bolt two are long screw bolts, and each long screw bolt will pass through all the bamboo materials in each group of structures.

[0049] When the round bamboo arch 100 is a structure with four groups arranged in parallel, the bolts one and the bolts two arranged along the width direction of the arc-shaped steel plate 11 are respectively two groups, wherein the bolts one are respectively connected to the two outer groups of structures, and the bolts two are connected to the two inner groups of structures.
