Description

Technical Field

[0001] This utility model relates to the field of prefabricated bamboo structure building technology, specifically to a connection structure for frame beams and floor beams in a reconstructed bamboo frame-shear wall structure. Background Technology

[0002] Reconstituted bamboo, as a new type of environmentally friendly building material, is increasingly widely used in prefabricated buildings. Column base connections are crucial for ensuring the overall stability of the structure. Traditional connection methods (such as mortise and tenon joints and adhesive bonding) suffer from problems such as weakened cross-sections, complex construction, and low seismic redundancy. In existing technologies, reconstituted bamboo columns are often directly embedded or connected to the foundation using simple bolts, which are difficult to effectively transfer horizontal shear forces and cannot achieve rigid anchoring. There is an urgent need for a column base connection structure that can both enhance shear resistance and facilitate assembly construction. Summary of the Invention

[0003] The purpose of this utility model is to provide a reconstituted bamboo column base connection structure with strong shear resistance and convenient construction. Through the rigid anchoring design of steel sleeve and through bolt, the problem of insufficient stability of traditional connection methods is solved.

[0004] To solve the above-mentioned technical problems, the technical solution proposed in this application is as follows:

[0005] A reconstituted bamboo column base connection structure includes:

[0006] Reconstructed bamboo frame columns;

[0007] A steel sleeve fitted onto the bottom of the reconstituted bamboo frame column;

[0008] Through bolts penetrating the steel sleeve and the reconstituted bamboo frame column;

[0009] Stiffening ribs welded to the outside of the steel sleeve;

[0010] The reconstituted bamboo frame column is inserted into the steel sleeve and connected laterally by the through bolts;

[0011] The stiffening ribs are vertically welded to the outer surface of the steel sleeve.

[0012] Furthermore, the cross-section of the reconstituted bamboo frame column is square or rectangular;

[0013] The inner wall shape of the steel sleeve matches the cross-sectional shape of the reconstituted bamboo frame column.

[0014] Furthermore, it also includes concrete foundations;

[0015] The steel sleeve is embedded in the concrete foundation.

[0016] Furthermore, the stiffening ribs are trapezoidal steel plates, symmetrically distributed along the circumference of the steel sleeve.

[0017] Compared with the prior art, the present invention achieves the following beneficial technical effects:

[0018] This invention achieves a reliable connection between the reconstituted bamboo column and the foundation through a rigid anchoring design using steel sleeves and through bolts, effectively transferring horizontal shear force. Welded stiffening ribs significantly enhance the shear bearing capacity and stability of the column base, preventing structural instability. The all-bolted connection method simplifies on-site construction, eliminating the need for complex processes and facilitating factory prefabrication and rapid on-site assembly, greatly improving construction efficiency. The overall structure exhibits reasonable stress distribution and superior seismic performance, providing a safe and efficient column base solution for prefabricated bamboo buildings, comprehensively improving the industrialization level and engineering applicability of the structure. Attached Figure Description

[0019] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0020] Figure 1 This is a schematic diagram of a reconstituted bamboo column base connection structure provided in an embodiment of the present invention.

[0021] In the diagram: 1-Reconstructed bamboo frame column, 2-Steel sleeve, 3-Through bolt, 4-Stiffening rib, 5-Concrete foundation. Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figure 1 As shown, this invention provides a reconstituted bamboo column base connection structure, which includes a reconstituted bamboo frame column 1, a steel sleeve 2, through bolts 3, and stiffening ribs 4. The reconstituted bamboo frame column 1 serves as the main load-bearing component, with the steel sleeve 2 fitted at its bottom. The two are laterally fastened together by the through bolts 3 to ensure effective force transmission. Stiffening ribs 4 are vertically welded to the outer side of the steel sleeve 2 to enhance the structure's stability and load-bearing capacity.

[0024] The cross-section of the reconstituted bamboo frame column 1 is preferably square or rectangular. Correspondingly, the inner wall shape of the steel sleeve 2 matches the cross-sectional shape of the reconstituted bamboo frame column 1 to ensure a tight fit and improve the reliability of the connection. In practical applications, appropriate cross-sectional dimensions can be selected according to specific engineering requirements.

[0025] Furthermore, the column base connection structure also includes a concrete foundation 5, with the steel sleeve 2 integrally embedded in the concrete foundation 5. During construction, the column bases are first connected and placed in the designated positions, and then the concrete foundation 5 is poured. This design allows the column base connection structure to better transfer the upper load to the foundation, improving the overall stability of the structure. During construction, the bond strength between the steel sleeve 2 and the concrete foundation 5 should be ensured, which can be achieved by setting shear keys or roughening the surface of the steel sleeve 2.

[0026] The stiffening ribs 4 are made of trapezoidal steel plates, symmetrically distributed around the circumference of the steel sleeve 2. This structural design not only effectively enhances the stiffness and stability of the steel sleeve 2, but also makes the load distribution more uniform. The specific dimensions and quantity of the trapezoidal steel plates can be optimized according to factors such as the cross-sectional dimensions and load size of the reconstituted bamboo frame column 1.

[0027] Through the above structural design, the reconstituted bamboo column base connection structure of the present invention has good mechanical properties and durability, which can meet the actual needs of engineering and provide a reliable connection method for the application of reconstituted bamboo structures in building engineering.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
