Abstract
Description
Technical Field
[0001] The utility model relates to the field of building construction, and particularly relates to a connecting node of an assembled original bamboo structure member. Background Art
[0002] China is the country with the richest bamboo resources in the world, ranking first in the world in terms of bamboo forest area, bamboo stock volume and bamboo production. Bamboo has excellent mechanical properties, and its tensile strength along the grain, compressive strength along the grain and elastic modulus are all superior to those of wood. The specific strength of bamboo is about 3-4 times that of steel. The energy consumption per unit area of the bamboo structure is relatively low, and its energy consumption per unit area is 1 / 3, 1 / 8 and 1 / 50 of that of the wood structure, concrete structure and steel structure respectively. In addition, the bamboo structure also has excellent seismic performance. Since the overall connection of the building with the original bamboo as the main body mostly relies on the traditional mortise and tenon structure for fixation during actual use, the overall tensile resistance is weak, directly resulting in weak overall seismic performance.

[0029] The following combines the attached Figure 1-6 to further elaborate on the present utility model in detail.
[0030] The embodiment of the present utility model discloses a connection node for assembled original bamboo structural components. Refer to Figure 1 - Figure 6, the connection node of the prefabricated bamboo structure members includes the connection node of the bamboo structure column 1 and the bamboo structure beam 2. Multiple steel sleeves I 3a are arranged on the bamboo structure column 1. The two ends of the steel sleeve I 3a pass through the bamboo of the bamboo structure column 1 and are inserted into the bamboo of the bamboo structure beam 2. Multiple fixing parts I 4a for fixing the bamboo structure beam 2 are arranged on the steel sleeve I 3a. The fixing part I 4a is a long bolt. The long bolt penetrates from the topmost one to the bottommost one of the steel sleeve I 3a. The long bolt is arranged on the steel sleeve I 3a in a horizontal and vertical state. Multiple grouting holes are reserved on the bamboo of the bamboo structure column 1 and the bamboo structure beam 2. It is connected by a special steel sleeve and a long bolt and is poured through the grouting holes. Phosphogypsum can be used as the grouting material. The treated phosphogypsum has high strength and short setting time. It can set in a few minutes and has a slight expansion property, avoiding detaching from the bamboo due to shrinkage caused by temperature changes in the later stage. There are natural diaphragms in the bamboo at certain intervals. The diaphragms can prevent the expansion of the grouting range inside the bamboo, realizing strong node connection. At the node, the phenomenon that the bamboo is weakened by drilling and cracks are prone to appear after drilling can be effectively avoided. The connection node is stable and reliable. The long bolt can also act as a shear connection shear to strengthen the connection between the grouting material and the bamboo.
[0031] In this embodiment, multiple connection holes through which the fixing part I 4a passes are reserved on the bamboo of the bamboo structure column 1 and the bamboo structure beam 2. Utilizing the fact that the inside of the bamboo is hollow, the bamboo is pre-drilled at a certain interval, and then fixed together by a special steel sleeve I 3a and a long bolt.
[0032] In this embodiment, multiple air vents are reserved on the bamboo of the bamboo structure column 1 and the bamboo structure beam 2. The air vents are reserved on the bamboo according to the required grouting length.
[0033] In this embodiment, the bamboo on the outer circle of the bamboo structure column 1 is not disconnected, and the bamboo on the inner circle of the bamboo structure column 1 is disconnected. The steel sleeve I 3a passes through the bamboo on the outer circle, and the disconnected bamboo on the inner circle is connected and fixed by a long bolt. The beam-column connection node has good seismic performance. At the node, the outer bamboo tube is not disconnected, which can effectively bear the eccentric tension generated by the earthquake action.
[0034] In this embodiment, it also includes the connection node of the bamboo wall 5 and the bamboo floor I 6. Multiple steel sleeves II 3b are arranged on the bamboo floor I 6. The two ends of the steel sleeve II 3b pass through the bamboo of the bamboo floor I 6 and are inserted into the bamboo of the bamboo wall 5. Multiple fixing parts II 4b for fixing the bamboo wall 5 on the bamboo floor I 6 are arranged on the steel sleeve II 3b. The fixing part II 4b is a long bolt, and the setting method is the same as the setting direction of the long bolt on the steel sleeve I 3a. Multiple grouting holes are reserved on the bamboo wall 5 and the bamboo floor I 6.
[0035] In this embodiment, connection holes for the fixing member II 4b to pass through are reserved on the raw bamboo of the raw bamboo wall 5 and the raw bamboo floor I 6. By taking advantage of the fact that the interior of the raw bamboo is hollow, the raw bamboo is pre-drilled at a certain interval, and then fixed together with a long bolt through a special steel sleeve II 3b.
[0036] In this embodiment, a plurality of air vents are reserved on the raw bamboo of the raw bamboo wall 5 and the raw bamboo floor I 6.
[0037] In this embodiment, it further includes the connection node of the raw bamboo structural beam 2 and the raw bamboo floor II 7. A plurality of fixing members III 4c for fixing are provided on the raw bamboo structural beam 2 and the raw bamboo floor II 7.
[0038] In this embodiment, connection holes for the fixing member III 4c to pass through are reserved on the raw bamboo of the raw bamboo structural beam 2 and the raw bamboo floor II 7. By taking advantage of the fact that the interior of the raw bamboo is hollow, the raw bamboo is pre-drilled at a certain interval, and then fixed together with a long bolt through a special steel sleeve III 3c.
[0039] In this embodiment, a plurality of grouting holes and air vents are reserved on the raw bamboo of the raw bamboo structural beam 2 and the raw bamboo floor II 7.
[0040] Specific examples are used in this article to elaborate on the principles and implementation manners of the present application. The descriptions of the above embodiments are only used to help understand the method and its core idea of the present application. The above are only the preferred implementation manners of the present application. It should be noted that due to the limited nature of literal expression and objectively infinite specific structures, for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements, refinements or changes can be made, or the above technical features can be combined in an appropriate manner; these improvements, refinements, changes or combinations, or directly applying the concept and technical solution of the utility model to other occasions without improvement, shall all be regarded as the protection scope of the present application.
