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] As an important form of low-carbon building, reconstituted bamboo structures typically rely on a floor system supported by frame beams and floor beams (cross braces). Existing connection methods have significant drawbacks:

[0003] 1) The mortise and tenon joint requires slotting in the reconstituted bamboo components, resulting in a cross-sectional loss rate of 15%-30%, which seriously weakens the load-bearing capacity of the beam; 2) Traditional corner bracket connections do not take into account the anisotropic characteristics of reconstituted bamboo, resulting in stress concentration at the nodes, which makes them prone to loosening and failure under long-term loads; Existing technologies struggle to balance efficient assembly with joint rigidity, resulting in poor construction precision and hindering applications in large-span floors. Therefore, there is an urgent need for a connection structure that can preserve the complete cross-section of components, enable rapid assembly, and ensure reliable force transmission. Summary of the Invention

[0004] This application aims to provide a fully bolted assembly connection structure for reconstituted bamboo frame beams and floor beams. By using L-shaped corner brackets to fix the sides of the frame beams and the ends of the floor beams in both directions, the traditional mortise and tenon process is avoided from weakening the beam cross-section. At the same time, it solves the problems of complex construction and low node reliability, realizes rapid assembly and rigid force transmission, and improves structural safety and construction efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution proposed in this application is as follows: This invention provides a connection structure between a reconstituted bamboo frame beam and a floor beam, comprising: Reconstructed bamboo frame beams, reconstructed bamboo floor beams, angle brackets, and bolts; The ends of the reconstituted bamboo floor beams are vertically connected to the sides of the reconstituted bamboo frame beams; The corner bracket is an L-shaped steel plate, with its first side plate fixedly connected to the side of the reconstituted bamboo frame beam by bolts, and its second side plate fixedly connected to the end of the reconstituted bamboo floor beam by bolts.

[0006] Furthermore, the bolts penetrate the angle brackets and the pre-set holes in the beam.

[0007] Furthermore, the reconstituted bamboo floor beams can be used as horizontal bracing.

[0008] Furthermore, the corner bracket is provided with stamped reinforcing ribs at the right-angle corners.

[0009] Furthermore, the number of bolts on each connecting surface shall not be less than two.

[0010] Furthermore, the bolts are galvanized high-strength bolts with a strength grade of 8.8 or higher.

[0011] Compared with the prior art, the present invention achieves the following beneficial technical effects: This application utilizes an L-shaped corner bracket and a fully bolted connection design to achieve efficient assembly of the reconstituted bamboo frame beams and floor beams, completely avoiding the weakening of the beam cross-section caused by mortise and tenon joints and ensuring the structural load-bearing capacity; it simplifies the construction process and reduces the technical difficulty of installation; the bidirectional rigid constraint of the corner brackets ensures effective load transfer, improves the reliability of the joints and seismic performance; at the same time, it supports non-destructive disassembly and reassembly, significantly improving resource utilization and aligning with the concept of green building. Attached Figure Description

[0012] 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.

[0014] The reference numerals in the attached drawings of this application include: 1. Reconstituted bamboo frame beam; 2. Reconstituted bamboo floor beam; 3. Angle bracket; 4. Bolt. Detailed Implementation

[0015] 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.

[0016] like Figure 1As shown, this embodiment relates to a connection structure between a reconstituted bamboo frame beam (main beam) and a floor beam (secondary beam). This structure mainly consists of a reconstituted bamboo frame beam 1, a reconstituted bamboo floor beam 2, angle brackets 3, and bolts 4. The ends of the reconstituted bamboo floor beam 2 are vertically connected to the sides of the reconstituted bamboo frame beam 1, thus forming a stable lateral and longitudinal support relationship. The angle bracket 3 adopts an L-shaped steel plate structure. Its first side plate is fixedly connected to the side of the reconstituted bamboo frame beam 1 by bolts 4, and its second side plate is similarly fixedly connected to the ends of the reconstituted bamboo floor beam 2 by bolts 4. Through the transition connection of the angle bracket 3, a stable connection between the reconstituted bamboo frame beam 1 and the reconstituted bamboo floor beam 2 is achieved.

[0017] Furthermore, during the connection process, bolt 4 will penetrate through angle bracket 3 and pre-drilled holes in the beam. This through-type connection method ensures that bolt 4 tightly fixes angle bracket 3 to the beam, preventing loosening or displacement and enhancing the reliability of the connection.

[0018] Furthermore, in addition to bearing the function of transmitting floor loads, the reconstituted bamboo floor beam 2 can also be used as a horizontal brace. When used as a horizontal brace, it can provide lateral support to the entire frame structure, improve the overall stability of the frame, and effectively resist the influence of lateral forces.

[0019] Furthermore, the corner bracket 3 is provided with stamped reinforcing ribs at its right-angle corners. These reinforcing ribs are formed by stamping, which can significantly enhance the structural strength and rigidity of the corner bracket 3, prevent deformation or damage due to stress concentration at the corners during the stress process, and extend the service life of the corner bracket 3.

[0020] Furthermore, each connecting surface uses no fewer than two bolts 4. The use of multiple bolts 4 can evenly distribute the load on the connecting surface, preventing a single bolt 4 from breaking due to excessive force, thus ensuring the load-bearing capacity of the connection.

[0021] Furthermore, bolt 4 is a galvanized high-strength bolt with a strength grade of 8.8 or higher. High-strength bolts provide sufficient preload and shear force to meet the strength requirements of the connection structure; while galvanizing effectively improves the corrosion resistance of bolt 4, ensuring it maintains good working condition in various environments and guaranteeing the long-term stability of the connection structure.

[0022] 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.
