Description

Technical Field

[0001] This utility model relates to a multi-cavity bamboo-wound tube vibration-free UHPC composite beam. Background Technology

[0002] In traditional buildings, beams are cast in one piece. During construction, formwork and temporary support structures need to be erected on site, and the formwork needs to be removed after casting. This method is inefficient and not only costly, but also because there is only one casting cavity inside the formwork. The weight of the cast beam is fixed after casting, which is not convenient to adjust and reduce the weight according to the actual building needs, making it inflexible. Utility Model Content

[0003] This invention addresses the aforementioned problems by providing a multi-cavity bamboo-wound tube vibration-free UHPC composite beam that is flexible in use and highly efficient in construction.

[0004] This utility model is constructed as follows: it includes a vertical cylindrical structure formed by splicing multiple square bamboo winding tubes, each of which has multiple cavities. Some or all of the cavities are filled with a vibration-free UHPC concrete layer. The exterior of the vertical cylindrical structure has a bamboo fiber layer to reinforce each square winding tube.

[0005] Furthermore, a stainless steel strip is also provided on the outside of the vertical cylindrical structure.

[0006] Furthermore, the vertical cylindrical structure is provided with nine square bamboo winding tubes, which are arranged in a nine-square grid. The nine square bamboo winding tubes include a first square bamboo winding tube, a second square bamboo winding tube, a third square bamboo winding tube, a fourth square bamboo winding tube, a fifth square bamboo winding tube, a sixth square bamboo winding tube, a seventh square bamboo winding tube, an eighth square bamboo winding tube, and a ninth square bamboo winding tube.

[0007] Furthermore, the first square bamboo winding tube, the third square bamboo winding tube, the seventh square bamboo winding tube, and the ninth square bamboo winding tube are provided with a vibration-free UHPC concrete layer, while the remaining square bamboo winding tubes are not provided with a vibration-free UHPC concrete layer.

[0008] Furthermore, the first, second, third, seventh, eighth, and ninth square bamboo winding tubes are provided with a vibration-free UHPC concrete layer, while the remaining square bamboo winding tubes are not provided with a vibration-free UHPC concrete layer.

[0009] Furthermore, the first, third, fourth, sixth, seventh, and ninth square bamboo winding tubes are provided with a vibration-free UHPC concrete layer, while the remaining square bamboo winding tubes are not provided with a vibration-free UHPC concrete layer.

[0010] Furthermore, except for the fifth square bamboo winding tube in the middle, which does not have a vibration-free UHPC concrete layer, the other eight square bamboo winding tubes all have a vibration-free UHPC concrete layer.

[0011] Furthermore, each of the nine square bamboo-wound tubes is equipped with a vibration-free UHPC concrete layer.

[0012] Furthermore, the first square bamboo winding tube, the third square bamboo winding tube, the seventh square bamboo winding tube, and the ninth square bamboo winding tube are set at the four corners.

[0013] Furthermore, the cavity is provided with reinforcing steel bars.

[0014] Compared with existing technologies, this utility model has the following advantages: The device has a simple structure and is easy to use. It can be adjusted and weight-reduced according to actual building needs, eliminating the need for formwork installation and removal, saving time and effort. It improves efficiency while ensuring the beam's ability to resist impact loads. It involves first creating multiple square bamboo-wound tubes, then connecting them in parallel to form a bundled tube structure. Finally, a layer of bamboo fiber and stainless steel strip is wrapped around the outside for reinforcement to form a whole. After the whole is formed, concrete can be poured into different cavities to correspond to different functions. Specifically, vibration-free UHPC can be selectively poured into several internal cavities to optimize the stress on the entire beam, such as corner filling, perimeter filling, or full filling. For example, corner filling solves impact problems; top and bottom filling provides bending resistance; left and right filling improves shear resistance; perimeter filling improves torsional resistance; and full filling comprehensively enhances all capabilities, but results in a larger self-weight.

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1-5 As shown, in this embodiment, a multi-cavity bamboo-wound tube vibration-free UHPC composite beam is provided, including a vertical cylinder structure 1 formed by splicing multiple square bamboo-wound tubes 11, multiple cavities 12 are formed inside the multiple square bamboo-wound tubes, and the multiple cavities form a multi-cavity box beam structure. A vibration-free UHPC concrete layer 13 is poured into part or all of the cavities, and the outside of the vertical cylinder structure has a bamboo fiber layer 14 for reinforcing each square winding tube.

[0018] This device is constructed by first creating multiple square bamboo winding tubes, then connecting these tubes in parallel to form a bundled tube structure. Finally, a layer of bamboo fiber is wrapped around the outside for reinforcement (or stainless steel strips can be used for further reinforcement), forming a unified structure. After the structure is complete, concrete can be poured into different cavities to suit various functions. Specifically, vibration-free UHPC can be selectively poured into several internal cavities to optimize the stress distribution of the entire beam. Options include corner filling, perimeter filling, and full filling. For example, corner filling addresses impact resistance; top and bottom filling provides bending resistance; left and right filling enhances shear resistance; perimeter filling improves torsional resistance; and full filling comprehensively enhances all capabilities, but results in a greater self-weight.

[0019] This device is formed by bonding multiple square bamboo winding tubes together to form a whole, and then reinforcing it with another layer of bamboo fiber on the outside, forming a bundle of bamboo winding tubes. It has very high strength and rigidity, which can improve the beam's ability to resist impact loads.

[0020] In this embodiment of the utility model, a stainless steel strip is also provided on the outside of the vertical cylinder structure.

[0021] In this embodiment of the utility model, nine square bamboo winding tubes are provided inside the vertical cylinder structure.

Among them, the first, third, seventh, and ninth square bamboo winding tubes are located at the four corners, which is a four-corner filling state, which can effectively solve the impact problem.

[0023] In the second embodiment of this utility model, as Figure 2 As shown, the first, second, third, seventh, eighth, and ninth square bamboo winding tubes are provided with a vibration-free UHPC concrete layer, while the remaining square bamboo winding tubes are not provided with a vibration-free UHPC concrete layer.

[0024] The above-mentioned filling method involves filling the front and rear sections, which can provide bending resistance.

[0025] In the third embodiment of this utility model, as Figure 3 As shown, the first, third, fourth, sixth, seventh, and ninth square bamboo winding tubes are provided with a vibration-free UHPC concrete layer, while the remaining square bamboo winding tubes are not provided with a vibration-free UHPC concrete layer.

[0026] The above-mentioned filling method is left and right filling, which can provide bending and shear resistance.

[0027] In the fourth embodiment of this utility model, as Figure 4 As shown, except for the fifth square bamboo winding tube in the middle which does not have a vibration-free UHPC concrete layer, the other eight square bamboo winding tubes all have a vibration-free UHPC concrete layer, namely the first square bamboo winding tube, the second square bamboo winding tube, the third square bamboo winding tube, the fourth square bamboo winding tube, the sixth square bamboo winding tube, the seventh square bamboo winding tube, the eighth square bamboo winding tube, and the ninth square bamboo winding tube.

[0028] The above-mentioned filling method is peripheral filling, which improves torsional resistance.

[0029] In embodiment five of this utility model, as Figure 5 As shown, each of the nine square bamboo-wound tubes has a vibration-free UHPC concrete layer inside. The above-mentioned filling method is full filling, which comprehensively improves various capabilities, but it has a large weight.

[0030] In this embodiment of the invention, the cavity is provided with reinforcing steel bars, which can be selectively arranged.
