Description

Technical Field

[0001] This utility model relates to the field of truss support technology, specifically to truss assembly jigs. Background Technology

[0002] In the field of steel structure construction, the precise assembly of trusses is a crucial step in ensuring the stability and safety of the overall structure. Truss assembly jigs, as auxiliary tooling specifically designed for truss assembly, have become core equipment for improving assembly efficiency and precision due to their role in fixing and supporting the positions of components. They can stably fix the various components of the truss according to preset dimensions and angles, effectively avoiding deformation or displacement caused by the self-weight of the components or external forces during assembly, thus laying a solid foundation for subsequent welding, acceptance, and other processes.

[0003] Existing truss assembly jigs mainly consist of four parts: a foundation frame, a support structure, a positioning device, and auxiliary components. The foundation frame is the load-bearing base of the jig, typically welded from structural steel (such as H-beams, I-beams, and channel steel). Its function is to evenly distribute the load of the jig to the ground. It needs to be fixed to the ground using embedded parts or expansion bolts to prevent overall displacement of the jig during use. The support structure, depending on the truss's structural form, can be divided into portal supports, frame supports, etc., used to directly support the truss's chords or web members. However, the support structure is generally welded to the foundation frame. While this ensures the stability of the support structure, it also means that the support height cannot be adjusted. In actual construction, when encountering scenarios where two trusses need to be joined at an angle, a fixed-height support structure cannot adapt to the height requirements at the angle of inclination. In such cases, it is necessary to replace the jig with one of the appropriate height to complete the assembly. This limitation not only increases the procurement cost and storage space of the jig, but also requires the preparation of multiple jigs for different tilt angles in advance, which prolongs the construction preparation time. At the same time, frequent jig replacements will reduce assembly efficiency and make it difficult to meet the flexible construction needs under complex working conditions. Utility Model Content

[0004] The purpose of this utility model is to provide a truss assembly jig, which is equipped with adjustable height support (15) to adapt to the scenario of truss tilt splicing.

[0005] To address the problems of existing technologies, this utility model provides a truss assembly jig for supporting the truss body. It includes: two main support frames distributed on both sides of the truss body, supporting two chords at the top of the truss body; and a secondary support frame installed between the two main support frames to support the web members at the bottom of the truss body. Each main support frame includes a vertically arranged support column, and the support column is equipped with a support member that is height-adjustable and supports the chords of the truss body. The support member is equipped with an adjustable positioning plate that limits the position of the chords of the truss body.

[0006] Preferably, the main support frame includes a through slot opened along the height direction of the support column, one end of the support member can be inserted into the through slot, the side of the main support frame is also provided with a second through hole along the length direction of the support column, and the main support frame also includes bolts that can be inserted into the second through hole for fixing the support member.

[0007] Preferably, the bottom of the support member is also provided with a support rod that contacts the support column at an incline. The support column is provided with a plurality of first through holes along its height direction, and the main support frame also includes bolts that can be inserted into the first through holes for fixing the support rod.

[0008] Preferably, the support member is rotatably provided with a screw along its length, and the top of the support member is also provided with a sliding groove along its length, and the bottom of the limiting plate is inserted into the sliding groove and threadedly connected to the screw. One end of the screw is also provided with a handwheel.

[0009] Preferably, the bottom of the support column is further provided with a base, and the two sides of the support column are further provided with reinforcing rods, forming a triangle with the base, the support column and the reinforcing rods.

[0010] Preferably, the secondary support frame includes two first channel steels that are detachably disposed between the two support columns, the secondary support frame also includes two second channel steels disposed perpendicular to the first channel steels, and the secondary support frame also includes two third channel steels disposed perpendicular to the second channel steels for limiting the web members at the bottom of the truss body.

[0011] Preferably, the first channel steel has a plurality of first waist holes along its length, the second channel steel has a second waist hole along its length, and the third channel steel has a third waist hole along its length.

[0012] The advantages of this utility model compared to the prior art are: This application effectively solves the height adaptation problem in truss tilting assembly scenarios by setting up support components that can be adjusted along the height direction of the support columns. When two trusses need to be assembled at an angle, the corresponding support components can be disassembled from the support columns and then reinstalled at specific positions according to the required support height based on the tilt angle. This matches the stress support requirements of the truss in the tilted state, avoiding the drawbacks of traditional jigs that require frequent replacement of jigs with corresponding heights due to fixed support heights, and significantly improving assembly flexibility. To address the adaptation requirements of truss chords of different sizes, this application designs a linkage adjustment structure between a screw and a limiting plate. By rotating the handwheel to drive the screw to rotate, the screw's helical transmission can move the limiting plate horizontally, causing an adaptive change in the distance between the limiting plate and the support column. This adjustment mechanism can stably adapt to chords of different cross-sectional dimensions, ensuring that the chords are always in a preset positioning state during assembly, improving the jig's compatibility with diverse chords. To prevent stress concentration and subsequent fracture at the weld joints connecting the chord and web members due to the weight of the web members, this application utilizes the truss body to provide stable support for the web members. Furthermore, by employing the position adjustment function of the second and third channel steels, their positions can be flexibly adjusted according to the actual height and cross-sectional dimensions of the web members, thus supporting web members of different specifications and further ensuring the structural stability of the welded joints.

[0020] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0021] Reference Figures 1-6 As shown, this utility model provides a truss assembly jig for supporting the truss body 3, including: a main support frame 1, which has two sets distributed on both sides of the truss body 3 and can support the two chords at the top of the truss body 3; and a secondary support frame 2, installed between the two main support frames 1, for supporting the web members at the bottom of the truss body 3. The main support frame 1 includes a vertically arranged support column 12, and the support column 12 is provided with a support member 15 that can be adjusted vertically and supports the chords of the truss body 3. The support member 15 is provided with a position-adjustable limiting plate 16 for limiting the position of the chords of the truss body 3.

[0022] When assembling and supporting the truss body 3, firstly, place the two sets of main support frames 1 at appropriate positions on both sides of the truss body 3. Based on the actual height of the top chord of the truss body 3, adjust the height of the support member 15 on the support column 12 of the main support frame 1 so that the support member 15 can support the position of the chord. Then, adjust the position of the upper limit plate 16 of the support member 15 so that it is tightly against the chord, limiting the chord and preventing horizontal movement. Next, install the secondary support frame 2 between the two main support frames 1, aligning its position with the web members at the bottom of the truss body 3, thereby supporting the web members. Through the support and limiting of the top chord of the truss body 3 by the main support frame 1, and the support of the bottom web members by the secondary support frame 2, the entire truss assembly jig provides a stable support system for the truss body 3.

[0023] The main support frame 1 includes a through slot 13 opened along the height direction of the support column 12. One end of the support member 15 can be inserted into the through slot 13. The side of the main support frame 1 also has a second through hole 122 opened along the length direction of the support column 12. The main support frame 1 also includes bolts that can be inserted into the second through hole 122 for fixing the support member 15.

[0024] Based on the height of the top chord of the truss body 3, insert one end of the support member 15 into the through slot 13 on the support column 12, insert the bolt into the second through hole 122, and ensure that the bolt passes through the support member 15. Then tighten the nut of the bolt so that the support member 15 is firmly fixed on the support column 12.

[0025] The bottom of the support member 15 is also inclinedly provided with a support rod 18 that contacts the support column 12. The support column 12 is provided with a number of first through holes 121 along its height direction, and the main support frame 1 also includes bolts that can be inserted into the first through holes 121 for fixing the support rod 18.

[0026] The support member 15 is rotatably provided with a screw 17 along its length direction, and the top of the support member 15 is also provided with a sliding groove along its length direction. The bottom of the limiting plate 16 is inserted into the sliding groove and threadedly connected to the screw 17. A handwheel is also provided at one end of the screw 17.

[0027] The operator turns the handwheel, which drives the screw 17 to rotate. Since the bottom of the limiting plate 16 is inserted into the groove at the top of the support member 15 and is threadedly connected to the screw 17, according to the principle of threaded transmission, the limiting plate 16 will move along the groove (i.e., the length direction of the support member 15). The operator continues to turn the handwheel according to the actual position of the chord member 3 of the truss body until the limiting plate 16 is tightly against the chord member, thus limiting the chord member and preventing horizontal movement.

[0028] The bottom of the support column 12 is also provided with a base 11, and the two sides of the support column 12 are also provided with reinforcing rods 14. The base 11, the support column 12 and the reinforcing rods 14 form a triangle.

[0029] The secondary support frame 2 includes two first channel steels 21, each detachably mounted between two support columns 12. The first channel steels 21 are typically connected by bolts or other detachable methods to fix their ends to corresponding parts on the support columns 12. The secondary support frame 2 also includes two second channel steels 22 perpendicular to the first channel steels 21, and two third channel steels 23 perpendicular to the second channel steels 22 for limiting the position of the web members at the bottom of the truss body 3. The first channel steels 21 have several first waist holes 211 along their length, the second channel steels 22 have second waist holes 221 along their length, and the third channel steels 23 have third waist holes 231 along their length.

[0030] When installing the second channel steel 22, it can be connected by bolts passing through the first waist hole 211 and the corresponding second waist hole 221 on the second channel steel 22. Because these are waist holes, the bolts can move within a certain range, providing flexibility for adjusting the position of the second channel steel 22. The position of the second channel steel 22 on the first channel steel 21 can be adjusted according to the size of the truss body 3 and installation requirements. When installing the third channel steel 23, bolts can be connected by passing through the second waist hole 221 and the third waist hole 231. The presence of the second waist hole 221 allows the third channel steel 23 to be adjusted along the length of the second channel steel 22 to accommodate the dimensions of the bottom web members of the truss body 3 of different specifications, ensuring that the third channel steel 23 can limit the movement of the web members.

[0031] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
