[0002] While steel trusses can meet various appearance requirements, they also bring more and greater challenges to construction companies, especially since steel trusses have the characteristics of strong load-bearing capacity, large span, good seismic performance, and low cost.

[0003] A search revealed Chinese patent CN209523488U, which discloses a truss assembly jig, comprising several support frames I and II arranged parallel to each other. Each support frame I and II includes a support platform with a connecting frame on it, and a receiving platform on the connecting frame. At least two sets of erection frames are also provided on the support platform II, each with a receiving platform. This utility model, through on-site assembly of the jig, provides high stability for truss chord members, is easy to assemble, and facilitates rapid assembly of the overall jig, helping construction workers to quickly assemble the jig, improving construction efficiency, and showing great promise for engineering application.

[0004] Based on the above search and existing technology, the findings were as follows:

[0005] The frame design of the aforementioned patents is suitable for conventional trusses, but may be insufficient for supporting irregular structures or ultra-large spans. Furthermore, the adjustment relies on a gear and rack system, and long-term use or frequent adjustment may cause wear on the locking mechanism, resulting in a risk of loosening. Therefore, it has certain limitations. Utility Model Content

[0007] The technical solution to achieve the purpose of this utility model is: an adjustable prefabricated truss assembly jig, including a base crossbar and a truss, and further including;

[0008] A support pole is installed at the bottom of the base crossbar by bolt threads, and a pair of support poles are threaded onto the base crossbar;

[0009] Ear plates, wherein multiple ear plates are provided, and ear plates are provided on the surface of the base crossbar and on one side of the support upright;

[0010] T-shaped steel plate, which is welded to one side of the base crossbar.

[0011] Preferably, the ear plate is connected to the surface of the base crossbar and one side of the support column by fastening bolts with two threads. A strong bolt is threaded on one side of the ear plate, and a transverse brace is threaded between a pair of ear plates by a strong bolt.

[0012] Preferably, a longitudinal connecting rod is installed on one side of the T-shaped steel plate by bolt thread, a connecting plate is provided between the longitudinal connecting rods, the connecting plate is installed between the longitudinal connecting rods by bolt thread, and an L-shaped steel plate is welded on the longitudinal connecting rod.

[0013] Preferably, both the support pole and the L-shaped steel plate are threaded with a fastening bolt, and a longitudinal diagonal brace is threadedly installed between the support pole and the L-shaped steel plate through the fastening bolt.

[0014] Preferably, each of the supporting uprights is provided with a bracket at its top, a chain hoist is fixedly installed between the bracket and the supporting upright, the top of the truss is installed on the surface of the bracket, a support block is fixedly installed on the base crossbar, and the bottom of the truss is installed on the surface of the support block.

[0015] Compared with existing technologies, the significant advantages of this invention are:

[0016] Firstly, this utility model uses standardized components and is assembled by bolt connection, eliminating the need for welding, reducing on-site operation time, and is convenient to transport. It can be disassembled into small units for easy transportation and storage, reducing logistics costs, making it economical, and reusable. One set of jigs can be used multiple times for different projects, reducing amortization costs.

[0017] Secondly, this utility model of the formwork can fix multiple truss sections, enabling overall hoisting after ground assembly, reducing the risk of high-altitude operations. Multiple formworks can work simultaneously, shortening the construction period. The bottom can be extended with supports or counterweights to prevent lateral instability, ensuring safety, reliability, and strong stability. It also reduces material waste and saves more temporary support materials compared to traditional wooden formwork or steel pipe supports.

[0018] This solves the problem that existing jig designs are suitable for conventional trusses, but may be insufficient for supporting irregular structures or ultra-large spans, and that the adjustment relies on a rack and pinion system, which may cause wear of the locking mechanism and create a risk of loosening if used for a long time or adjusted frequently.

Obviously, the described embodiments are only some embodiments of the present invention, and 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 protection scope of the present invention.

[0028] This utility model provides an adjustable prefabricated truss assembly jig through improvements. The technical solution of this utility model is as follows:

[0029] like Figures 1-5 As shown, an adjustable prefabricated truss assembly jig includes a base crossbar 1 and a truss 2, which takes into account rigidity, stability and safety, and also includes;

[0030] Supporting uprights 3 are installed at the bottom of the base crossbar 1 by bolt threads. A pair of supporting uprights 3 are threaded on the base crossbar 1 to improve the overall load-bearing capacity and support force of the structure.

[0031] Ear plates 6 are provided in multiple ways. Ear plates 6 are provided on the surface of the base crossbar 1 and on one side of the support upright 3. The ear plates 6 are connected by pins to form hinge points, which reduces secondary stress and avoids cracks in the structure due to rigid connection.

[0032] T-shaped steel plate 13 is welded to one side of the base crossbar 1. It can prevent buckling by welding stiffening ribs, resulting in strong structural stability.

[0033] Furthermore, the ear plate 6 is connected to the surface of the base crossbar 1 and one side of the support column 3 by fastening bolts 10. A strong bolt 11 is threaded on one side of the ear plate 6. A transverse brace 5 is threaded between a pair of ear plates 6 by strong bolts 11. Construction is convenient, standardized components are used, and the components are prefabricated in the factory and bolted on site, reducing the amount of welding and making installation convenient.

[0034] Furthermore, a longitudinal connecting rod 4 is installed on one side of the T-shaped steel plate 13 by bolt thread, and a connecting plate 15 is provided between the longitudinal connecting rods 4. The connecting plate 15 is installed between the longitudinal connecting rods 4 by bolt thread, and an L-shaped steel plate 14 is welded on the longitudinal connecting rods 4. The steel plate components are produced in a standardized manner in the factory, reducing on-site construction time and improving project efficiency.

[0035] As a further embodiment of this utility model, both the support pole 3 and the L-shaped steel plate 14 are threaded with fastening bolts 7. A longitudinal diagonal brace 9 is threaded between the support pole 3 and the L-shaped steel plate 14 through the fastening bolts 7. The diagonal brace forms a triangular stabilizing unit, which converts the horizontal force into axial tension or pressure and transmits it to the foundation, thereby reducing structural lateral displacement.

[0036] Furthermore, each support column 3 is equipped with a bracket 12 at its top, and a chain hoist 8 is fixedly installed between the bracket 12 and the support column 3. The top of the truss 2 is installed on the surface of the bracket 12, and a support block 101 is fixedly installed on the base crossbar 1. The bottom of the truss 2 is installed on the surface of the support block 101. By controlling the lifting and lowering of the chain, the steel structure components can be finely adjusted to ensure installation accuracy.

[0037] The specific working method is as follows: the base crossbar 1, support upright 3, longitudinal connecting rod 4, and bracket 12 are all I-beams; the transverse diagonal brace 5 is a round tube; and the longitudinal diagonal brace 9 is an angle steel. The bracket 12 is connected to the support upright 3 by a chain hoist 8. The bracket 12 can slide along the flange of the support upright 3. The height of the bracket 12 can be adjusted by the chain hoist 8, thereby adjusting the setting height of the truss 2. The support upright 3 is connected to the base crossbar 1 by bolts. A row of bolt holes is opened on the upper flange of the base crossbar 1 to facilitate the adjustment of the upright spacing according to actual needs. The transverse diagonal brace 5 is connected by pins at both ends. The connection between the transverse diagonal brace 5 and the base crossbar 1 is an adjustable sliding node. After installation, it is fixed by tightening with bolts. The longitudinal connecting rod 4 is a multi-segment design, which can adjust the spacing between the components of the frame and adjust the overall load-bearing capacity of the frame.
