Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a positioning and installation jig for large-span steel trusses. Background Technology

[0002] When constructing steel trusses, a high-altitude hoisting and assembly method can be used, with the chord members lifted to a high altitude by large cranes. However, this method incurs significant machinery costs and carries substantial safety risks. Therefore, a ground-based assembly and overall lifting method is preferred, requiring a jig for the truss during ground assembly. For example, Chinese Utility Model Patent Publication No. CN221143605 U discloses a large-span steel truss operation and assembly jig, including a jig body and a cantilever platform. Multiple jig bodies are spaced apart along the axial direction of the steel truss. The cantilever platform is located on the upper part of the jig body away from the steel truss and includes a triangular support, a step, and a guardrail. One side of the triangular support is fixed to the jig body, and the guardrail is fixed to the other side of the triangular support and extends along the axial direction of the steel truss. The step is located at the top of the triangular support, between the jig body and the guardrail, and extends along the axial direction of the steel truss. This method is inconvenient for flexible personnel access during construction. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a positioning and installation jig for a large-span steel truss, which is conducive to the flexible operation of construction personnel, allows for selection of construction positions along the longitudinal direction of the jig, and facilitates the flexible transportation of various tools required for construction.

[0004] To solve the above problems, a large-span steel truss positioning and installation jig was adopted, which includes:

[0005] Multiple transfer beams are installed at intervals.

[0006] Columns are installed at intervals on the transfer beam;

[0007] A horizontal bar, which is installed horizontally between two uprights;

[0008] The horse-walking brackets are installed horizontally on both sides of the uprights;

[0009] The first horse track beam is installed at intervals on the horse track corbels;

[0010] Steel mesh is laid on the first joist beam;

[0011] A support beam, which is installed horizontally on the upper end of the column;

[0012] The pads are installed on the pad beams and crossbars respectively;

[0013] Baffles are installed on both sides of the pad;

[0014] The first galvanized steel pipe is installed on the first sidewalk beam;

[0015] The temporary staircase has a first channel steel installed on its upper front side. The first channel steel is slidably assembled on the first galvanized steel pipe, and foot brake wheels are installed at the four corners of its bottom.

[0016] With this structure, construction workers can access the steel mesh via temporary stairs for convenient maintenance and work. The steel mesh forms a working platform, allowing workers to quickly descend to the ground or elevated floor. The transfer beams directly transfer the load to the column ends, preventing the elevated floor from bearing the load directly. The temporary stairs also facilitate the timely transport of welding tools or testing equipment. The temporary stairs, guided by foot brakes and the sliding of the first channel steel and the first galvanized steel pipe, allow them to flexibly find access points. When the overall steel truss is long, this improves efficiency.

[0017] As a further improvement of this utility model, a second walkway beam is provided between the front and rear spaced columns, and the steel mesh is laid on the second walkway beam and a second galvanized steel pipe is installed; a second channel steel is installed on both sides of the top surface of the platform plate at the top of the temporary staircase, and the second channel steel is slidably adapted to install a first telescopic walkway, and the extended end of the first telescopic walkway overlaps the second galvanized steel pipe.

[0018] With this structure, the temporary staircase can be extended into the steel mesh area by installing the first telescopic walkway, so that workers are protected on both sides to ensure safety.

[0019] As a further improvement of this utility model, a third galvanized steel pipe is installed on the first inner walkway beam; a third channel steel is installed on both sides of the top surface of the first walkway plate of the first telescopic walkway; the third channel steel is slidably fitted to install a second telescopic walkway; the second telescopic walkway overlaps on the third galvanized steel pipe.

[0020] With this structure, the second retractable walkway can extend directly to the steel truss, preventing construction workers from stepping directly on the steel mesh. This allows the steel mesh to act as a safety net and other protective measures, avoiding direct load bearing and potential damage.

[0021] As a further improvement of this utility model, the end of the second walkway panel of the second telescopic walkway is cantilevered and a safety hanging cage hanging interface is provided.

[0022] With this structure, the safety cage mounting interface is used to attach the safety cage, allowing construction workers to further access the steel truss and weld the various chords and web members of the steel truss.

[0023] As a further improvement of this utility model, the conversion beam, column, crossbar, crossbeam bracket, first crossbeam, pad beam, and second crossbeam are all made of I-beams, with ribs spaced inside the I-beams, and ribs are also provided on the bottom surface of the end of the second crossbeam.

[0024] As a further improvement of this utility model, an I-beam pad is provided under the crossbeam connected to the inner side of the column; the I-beam pad is installed on the crossbar.

[0025] With this structure, the I-beam pads are beneficial for supporting the inner corbels.

[0026] As a further improvement of this utility model, a diagonal brace is provided under the crossbeam connected to the outer side of the column, and the lower end of the diagonal brace is installed on the column.

[0027] With this structure, the diagonal bracing helps to support the outer corbels of the horse track.

[0028] As a further improvement of this utility model, a fourth galvanized steel pipe is provided on both sides of the bottom surface of the first walkway plate of the first telescopic walkway to slide and adapt to the second channel steel.

[0029] With this structure, the first telescopic walkway can slide and extend with the second channel steel.

[0030] As a further improvement of this utility model, the bottom surfaces of the second walkway plate of the second telescopic walkway are provided with fifth galvanized steel pipes that slide to fit the third channel steel.

[0031] With this structure, the second telescopic walkway can slide and extend with the third channel steel.

[0032] As a further improvement of this utility model, handrails are provided on both sides of the top surface of the first walkway and the second walkway.

[0033] With this structure, the handrails can further enhance the protection of workers and help ensure operational safety.

[0034] This utility model allows construction workers to flexibly access and operate the equipment, enabling them to select construction locations along the longitudinal direction of the support frame and flexibly transport various tools required for construction. Attached Figure Description

[0061] With this structure, construction workers can access the steel mesh via the temporary staircase 11 for convenient maintenance and work.

[0077] In this embodiment, handrails 20 are provided on both sides of the top surface of the first walkway 1401 and the second walkway 1601.

[0078] With this structure, the handrail 20 can further enhance the protection of workers and help ensure work safety.
