Description
Technical Field
[0001] This utility model belongs to the field of frame technology, and more specifically, it relates to a prefabricated frame factory node. Background Technology
[0002] Due to their large spans, spacious layouts, and high load-bearing capacity, frame-type factory buildings are widely used in industrial fields such as machinery manufacturing, metallurgical processing, logistics warehousing, and heavy equipment production, serving as a building form to support industrial production activities. These factory buildings not only need to meet the spatial layout requirements of daily production but also need to bear the loads of heavy equipment such as overhead cranes and machine tools, placing stringent requirements on structural stability, load-bearing safety, and long-term durability.
[0003] Existing prefabricated frame factory buildings mostly adopt cast-in-place concrete structural systems. Their construction process requires sequential completion of site leveling, foundation excavation, formwork erection, rebar tying, concrete pouring, and curing on-site. The entire process involves a large amount of on-site wet work, is highly dependent on the technical skills of construction workers, and is significantly affected by weather conditions. Rainy days can easily interrupt concrete pouring, and low-temperature environments require additional insulation measures to ensure concrete strength development, further extending the construction period. Therefore, there is a need for a prefabricated frame factory building node that requires less on-site work and has higher construction efficiency. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a prefabricated frame factory building node, which solves the technical problem that traditional frame factory buildings mostly use cast-in-place concrete structures, involve a large amount of on-site wet work, and are easily affected by the environment, thus prolonging the construction period.
[0005] The purpose and effect of this utility model for a prefabricated frame factory building node are achieved by the following specific technical means: A prefabricated frame workshop node includes a prefabricated cup-shaped base. The top of the prefabricated cup-shaped base is provided with an assembly groove. The bottom end of the prefabricated frame column passes through the assembly groove. A fixing layer formed by grouting is provided in the assembly groove. The fixing layer is located between the inner wall of the assembly groove and the prefabricated frame column. The precast frame column is provided with an assembly assembly at the top. The assembly assembly includes two sets of first precast connecting beams. A first corbel is provided on one side of the precast frame column. The adjacent ends of the two sets of first precast connecting beams are connected to the first corbel.
[0006] According to a preferred embodiment, a second corbel is also provided on one side of the precast frame column, the second corbel is located above the first corbel, and two sets of second precast connecting beams are provided on the top of the second corbel.
[0007] According to a preferred embodiment, two sets of beam-column embedded steel plates are provided on one side of the precast frame column. The two sets of beam-column embedded steel plates are located above the first corbel and the second corbel, respectively. An L-shaped steel plate is provided at one end of each of the two sets of first precast connecting beams and the two sets of second precast connecting beams. The two sets of beam-column embedded steel plates are welded to the two sets of L-shaped steel plates, respectively.
[0008] According to a preferred embodiment, a gantry crane bracket is provided on the side of the prefabricated frame column away from the first bracket, the gantry crane bracket is located above the second bracket, and a gantry rail embedded part is provided on the top of the gantry crane bracket.
[0009] According to a preferred embodiment, a first lifting hole is provided on one side of each of the two sets of first precast connecting beams and the two sets of second precast connecting beams, and a first lifting ring is provided on one side of the precast frame column. The first lifting ring is located between the first corbel and the second corbel, and a through second lifting hole is provided on the side of the precast frame column adjacent to the first lifting ring.
[0010] According to a preferred embodiment, a third corbel is provided at the top of the precast frame column, and a roof steel beam connecting steel plate is provided on both the top of the precast frame column and the third corbel.
[0011] According to a preferred embodiment, the top of the precast cup-shaped base is provided with two sets of piers, both sets of piers are located on one side of the precast frame column, the tops of the two sets of piers are respectively connected to two sets of precast foundation beams, and a third hoisting hole is opened on both sets of precast foundation beams.
[0012] According to a preferred embodiment, a second lifting ring is provided on one side of the precast frame column, and the second lifting ring is located between the two sets of piers and the first corbel.
[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The precast cup-shaped base, precast frame columns, first precast connecting beam, second precast connecting beam, and precast foundation beam of this node are all precast in the factory in a standardized manner. Only assembly and a small amount of grouting work need to be completed on site. After the bottom end of the precast frame column is inserted into the assembly groove of the precast cup-shaped base, only grout needs to be poured into the assembly groove to form a fixed layer. Unlike traditional cast-in-place structures, there is no need to set up formwork, tie steel bars, or pour large areas of concrete on site. Compared with traditional cast-in-place wet work, the grouting work involves less work, is more convenient to operate, and has a higher tolerance to environmental conditions. It avoids construction interruptions or delays due to environmental factors such as rain and low temperature. At the same time, the quality of factory-precast components is easier to control, reducing problems such as insufficient concrete density and dimensional deviations that may occur during on-site pouring, and reducing the time spent on later repairs.
[0014] 2. Using the first and second lifting rings on one side of the precast frame column, the frame column can be directly lifted onto the precast cup-shaped base and inserted into the assembly slot using hoisting equipment. The first and third lifting holes on the first and second precast connecting beams and the precast foundation beam facilitate the stable lifting of components by hoisting equipment. The connecting beams can be directly placed on the top of the first and second corbels of the precast frame column without the need for on-site measurement and adjustment of the support height. At the same time, the pre-embedded steel plates of the precast frame column beams and the L-shaped steel plates of the connecting beams can be directly welded and fixed, eliminating the need for repeated calibration of hole positions required by traditional bolt connections. The piers on top of the precast cup-shaped base provide stable support for the precast foundation beams, eliminating the need for on-site pouring of foundation beam support structures. The entire installation process requires no complex on-site processing, reducing on-site manual operation time and shortening the construction cycle.
[0015] 3. The grouting fixing layer between the precast frame columns and the base can fill the gap between the inner wall of the assembly groove and the frame columns, forming a close-fitting connection structure and improving the column's anti-overturning and load-bearing capacity. The connecting beams and frame columns are welded to L-shaped steel plates embedded in the beams and columns, resulting in high connection strength and avoiding the problem of loosening easily after long-term use of traditional bolt connections. At the same time, the pre-embedded crane brackets and crane rail embedded parts on the precast frame columns can be directly used to install the crane rails without the need to drill holes or pour brackets on the frame columns later, thus avoiding damage to the integrity of the column structure. The roof steel beam connecting steel plates at the top of the precast frame columns and on the third bracket can be directly connected to the roof steel structure without the need for on-site welding or drilling, reducing roof installation procedures. This not only ensures the stability of the node structure but also directly adapts to the functional requirements of the factory building, such as crane installation and roof construction, avoiding structural modifications due to functional upgrades later and reducing maintenance and adjustment costs.

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0019] Example: As attached Figure 1 To be continued Figure 2 As shown: This utility model provides a prefabricated frame workshop node, including a prefabricated cup-shaped base 11. The top of the prefabricated cup-shaped base 11 is provided with an assembly groove. The bottom end of the prefabricated frame column 13 passes through the assembly groove. A fixing layer 14 formed by grouting is provided in the assembly groove. The fixing layer 14 is made of high-strength non-shrink grout. During grouting, it is injected from the grouting hole on one side of the assembly groove until it flows out from the overflow hole on the other side, ensuring that the grout fills the gap between the inner wall of the assembly groove and the prefabricated frame column 13. The fixing layer 14 is located between the inner wall of the assembly groove and the prefabricated frame column 13. An assembly assembly is provided on the top of the prefabricated frame column 13. The assembly assembly includes two sets of first prefabricated connecting beams 21. A first corbel 22 integrally formed with the column body is prefabricated on one side of the prefabricated frame column 13. The adjacent ends of the two sets of first prefabricated connecting beams 21 are resting on the top of the first corbel 22.
[0020] Specifically, using prefabricated cup-shaped bases 11, prefabricated frame columns 13, and assembly components, only assembly and a small amount of grouting work need to be completed on-site. Construction workers first fix the prefabricated cup-shaped bases 11 in the foundation pit using pre-embedded bolts. Then, using a truck crane and wire ropes, they hook the lifting rings of the prefabricated frame columns 13 and slowly insert the bottom end of the prefabricated frame columns 13 into the assembly slot of the prefabricated cup-shaped bases 11. The verticality of the column is adjusted using a level, and then high-strength, non-shrink grout is poured into the assembly slot. Under gravity, the grout fills the gaps, and after hardening, forms a fixing layer 14. The precast frame columns enhance the overturning resistance and load-bearing capacity. Unlike traditional cast-in-place structures, the entire process does not require the on-site erection of large-area formwork, manual tying of complex steel bars, or large-area concrete pouring. Compared to traditional wet casting, grouting involves less work, is more convenient, and has higher tolerance to environmental conditions. It avoids construction interruptions or delays due to environmental factors such as rain or low temperatures. At the same time, the quality of factory-precast components is easier to control, reducing problems such as insufficient concrete density and dimensional deviations that may occur during on-site pouring, and reducing the time spent on later repairs.
[0021] Please refer to, for example Figure 1 and Figure 2As shown, a second corbel 23, integrally formed with the column body, is prefabricated on one side of the prefabricated frame column 13. The structure of the second corbel 23 is the same as that of the first corbel 22, and it is located above the first corbel 22. Two sets of second prefabricated connecting beams 24 are set on the top of the second corbel 23. Two sets of beam-column embedded steel plates 25 are prefabricated on one side of the prefabricated frame column 13, and the two sets of beam-column embedded steel plates 25 are located above the first corbel 22 and the second corbel 23, respectively. L-shaped steel plates 26 are welded to the adjacent ends of the two sets of first prefabricated connecting beams 21 and the two sets of second prefabricated connecting beams 24. The two sets of beam-column embedded steel plates 25 are fully welded to the two sets of L-shaped steel plates 26, which eliminates the need for repeated calibration of bolt hole positions required by traditional bolt connections. At the same time, the shear and tensile strength of the welded connection is stronger, avoiding the problems of bolt loosening and gasket aging that are prone to occur with long-term use of traditional bolt connections.
[0022] A crane bracket 27 is prefabricated on the side of the prefabricated frame column 13 away from the first bracket 22. A crane rail embedded part 28 is pre-embedded in the top of the crane bracket 27. During use, the crane rail can be directly connected and fixed to the crane rail embedded part 28 by bolts through the rail holes, eliminating the need to drill holes in the prefabricated frame column 13 or cast the crane bracket 27 on-site, thus avoiding damage to the structural integrity of the prefabricated frame column 13. Two sets of first prefabricated connecting beams 21 and two sets of second prefabricated connecting beams 24 each have a circular first lifting hole 29 on one side. A first lifting ring 30 is pre-embedded on one side of the prefabricated frame column 13, located between the first bracket 22 and the second bracket 23. A through circular second lifting hole 31 is provided on the side adjacent to the first lifting ring 30; a third bracket 32 is prefabricated at the top of the prefabricated frame column 13, and the third bracket 32 is integrally formed with the prefabricated frame column 13. Roof steel beam connecting steel plates 33 are pre-embedded on the top of the prefabricated frame column 13 and the third bracket 32. When installing the roof steel beam, the connecting plate at the end of the steel beam can be directly connected and fixed to the roof steel beam connecting steel plate 33 by high-strength bolts, reducing the roof installation process; it not only ensures the stability of the node structure, but also directly adapts to the functional requirements of the factory's crane installation, roof construction, etc., avoiding the need to modify the structure due to functional upgrades in the later stage, and reducing maintenance and adjustment costs.
[0023] Please refer to, for example Figure 1 and Figure 2 As shown, the precast cup-shaped base 11 has two sets of piers 15 on its top. Both sets of piers 15 are located on one side of the precast frame column 13. The tops of the two sets of piers 15 are connected to two sets of precast foundation beams 16, and each set of precast foundation beams 16 has a circular third lifting hole 17. A second lifting ring 18 is provided on one side of the precast frame column 13, and the second lifting ring 18 is located between the two sets of piers 15 and the first corbel 22.
[0024] Specifically, during on-site installation, the precast frame column 13 can be smoothly lifted using the first lifting ring 30 and the second lifting ring 18 in conjunction with the double hooks of the truck crane: the main hook of the crane hooks the first lifting ring 30, and the auxiliary hook hooks the second lifting ring 18. After slow lifting, the length of the lifting rope is adjusted to keep the precast frame column 13 vertical. Then, the bottom end of the column is aligned with the assembly groove of the precast cup-shaped base 11 and slowly placed into the groove without additional manual support or adjustment of the column's orientation. The first lifting hole 29 and the third lifting hole are opened on the first precast connecting beam 21, the second precast connecting beam 24, and the precast foundation beam 16. 17. This design facilitates direct insertion of the crane hook for lifting, avoiding the need to tie lifting ropes to the surface of the components. Furthermore, the orientation of the components can be precisely controlled through the holes during lifting, ensuring that the first precast connecting beam 21 and the second precast connecting beam 24 can be stably placed on top of the first corbel 22 and the second corbel 23 of the precast frame column 13 without the need for on-site measurement and adjustment of the support height. The pier 15 on top of the precast cup-shaped base 11 provides stable support for the precast foundation beam 16, eliminating the need for on-site pouring of the foundation beam support structure. The entire installation process requires no complex on-site processing, reducing on-site manual operation time and shortening the construction cycle.
