Description

Technical Field

[0001] This utility model relates to the field of building structure engineering technology, and in particular to a prefabricated main and secondary beam connection node. Background Technology

[0002] A beam supported on a column is a main beam, and a beam supported on either a main beam or a secondary beam is a secondary beam. Considering both the characteristics of the load and the structural aspects, the load is transferred from the slab to the secondary beam, then to the main beam, and finally to the column. Therefore, main beams are generally supported on columns, while secondary beams are supported on main beams.

[0003] Chinese Patent No. CN209011314U discloses a novel prefabricated main-secondary beam connection node, including a main beam and a secondary beam. Secondary beam support platforms are provided on both sides of the main beam. Pre-embedded bolts are installed in the middle of the secondary beam support platforms on the main beam. Pre-reserved bolt holes are provided inside the secondary beam, with their positions matching the pre-embedded bolts. Fastening nuts are provided behind the pre-embedded bolt holes. A fixing opening is provided at the top of the secondary beam. The height and width of the secondary beam support platforms are the same as the secondary beam. The secondary beam support platforms and pre-embedded bolts are symmetrically arranged. This utility model relates to the field of prefabricated construction technology. This novel prefabricated main-secondary beam connection node and its connection method effectively improve the production efficiency of the prefabricated construction industry, avoid the need for steel reinforcement binding and concrete pouring during the connection of main and secondary beams in current prefabricated construction, increase the assembly rate, improve the structural level of prefabricated construction, and promote the advancement of the building industrialization.

[0004] Existing prefabricated main and secondary beam connection nodes use pre-embedded bolts and bolt holes. However, when the bolts are used to support heavy building structures, their load-bearing capacity may be insufficient, causing the bolts to fail due to excessive stress during actual use. This results in unstable use of the main and secondary beam connection nodes and affects normal operation. Utility Model Content

[0027] Example 1

[0028] like Figure 1 - Figure 4 As shown, the present invention proposes a prefabricated main and secondary beam connection node, comprising: a base 1, a main beam support 2, a secondary beam assembly, and mounting blocks 5; the base 1 is provided with a groove, which connects to the main beam support 2; the main beam support 2 is provided with an opening, and the two sides inside the opening are respectively connected to a reinforcing plate 201 and four base plates 203, the four base plates 203 are in pairs, and the two sets of base plates 203 are respectively connected to the upper and lower parts of the reinforcing plate 201 to form an interlocking chamber; the secondary beam assembly is connected to both sides of the main beam support 2; the secondary beam assembly includes a secondary beam support a3 and a secondary beam support b4, the connecting end of the secondary beam support b4 is connected to an interlocking plate 404 and the upper part is connected to a vertical plate 405, the two sides of the vertical plate 405 are respectively connected to mounting rods 406, and the mounting rods 406 are provided with reserved mounting holes; two mounting blocks 5 are provided and are respectively connected to the mounting rods 406. By connecting the secondary beam a3 and secondary beam b4 in the interlocking chamber through the interlocking plate 404, the connection structure between the secondary beam assembly and the main beam is increased. Then, in conjunction with the pre-embedded bolts 402 and the reserved bolt holes, and further in conjunction with the base 1, the mounting block 5 and the connecting block 501, the load-bearing capacity is increased sufficiently, the instability of the main and secondary beam connection nodes is avoided, and the normal use of the main and secondary beam connection nodes is improved.

[0029] Further explanation: The interlocking plate 404 is connected within the interlocking chamber, and bolts pass through the mounting block 5 and are threadedly connected to the pre-reserved mounting hole a, allowing for a detachable connection between the mounting block 5 and the mounting rod 406; the reinforcing plate 201 has a through hole 202 for the pre-embedded bolt 402 to pass through and connect to the pre-reserved bolt hole; the main beam bearing platform 2 has a reinforcing hole 204, with the bottom of the reinforcing hole 204 extending into the base 1, and a sealing hole at the upper end of the reinforcing hole 204, which connects to the sealing plate a205; the secondary beam assembly is connected above the base 1 and is detachable. The through hole 202 is located on the reinforcing plate 201, and the pre-embedded bolt 402 needs to pass through the through hole 202 and connect to the pre-reserved bolt hole. The reinforcing plate 201 is connected to the main beam bearing platform 2, providing guidance for the installation of the pre-embedded bolt 402 and improving the efficiency of the connection operation between the pre-embedded bolt 402 and the pre-reserved bolt hole.

[0030] To further explain, mounting block 5 is connected to connecting block 501, which is connected to both sides of the main beam bearing platform 2. Bolts are used to pass through the connecting block 501 and connect it to the pre-drilled mounting holes b, allowing for a detachable connection between the connecting block 501 and the main beam bearing platform 2.

[0031] Example 2

[0032] like Figure 1 and Figure 4 As shown, this utility model proposes a prefabricated main and secondary beam connection node. Based on the above embodiments, this embodiment also details the specific components of the secondary beam assembly and their assembly method.

[0033] To further explain, the secondary beam pier b4 has a hollow interior serving as an installation chamber, with open and fixed openings 401 at both ends for external connection. Pre-embedded bolts 402 are connected inside the installation chamber, and a sealing plate b403 is connected to the fixed opening 401 for opening or closing the fixed opening 401 to operate the pre-embedded bolts 402. The secondary beam pier a3 and secondary beam pier b4 have the same external connection structure, and the installation chamber inside secondary beam pier a3 is connected to a reserved bolt hole a for connection with the pre-embedded bolts 402. The secondary beam assembly is connected to the main beam pier 2 via the pre-embedded bolts 402 and reserved bolt holes. After connection, cement mortar is used to fill the openings, sealing the interior and forming a sealing plate b403 at the fixed opening 401 end, thus filling the gaps with cement mortar and improving the connection between the secondary beam assembly and the main beam pier 2.

[0034] The working principle of this utility model is as follows: During the assembly operation of the main and secondary beam connection node, the operator inserts the insertion plate 404 of the connection end of the secondary beam a3 and secondary beam b4 into the insertion chamber, and then operates the pre-embedded bolt 402 in the secondary beam b4 through the fixed opening 401, so that the reserved bolt hole in the secondary beam a3 is connected, and then the pre-embedded bolt 402 passes through the through hole 202 and connects with the reserved bolt hole, thereby achieving the connection between the secondary beam assembly and the main beam a2. With the insertion plate 404 and the insertion chamber, the connection structure is increased and the stability is improved. The connection is achieved through the base 1 and the main beam a2. Cement mortar is added into the reinforcing hole 204, and the cement mortar cures and forms a sealing plate a205 at the top. The sealing plate a205 seals the reinforcing hole 204, making the connection between the base 1 and the main beam bearing platform 2 stable, and supporting the secondary beam assembly on the base 1, increasing the support effect of the secondary beam assembly. The mounting block 5 is connected to both sides of the secondary beam assembly and to the main beam bearing platform 2, using bolts and reserved mounting holes b to achieve the connection between the mounting block 5 and the main beam bearing platform 2. The mounting block 5 drives the connecting block 501 and the mounting rod 406 to connect, using bolts and reserved mounting holes a to achieve the connection between the connecting block 501 and the mounting rod 406. The mounting rod 406 is connected to the secondary beam assembly through the vertical plate 405, which facilitates the addition of the connection structure between the main beam bearing platform 2 and the secondary beam assembly, further improving the stability of the prefabricated main and secondary beam connection nodes.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
