Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a prefabricated cross truss platform. Background Technology

[0002] For example, Chinese Utility Model Patent Publication No. CN 104895314 A discloses a truss platform for concrete construction of a tall, spacious roof slab. It includes truss support iron parts, steel brackets fixedly connected to the truss support iron parts, rails installed on the steel brackets, and a steel frame truss installed on the rails. The steel frame truss can slide on the rails, and a base plate is laid on the steel frame truss. A full-span scaffold, supporting walers, and formwork are erected on the base plate. This involves the entire truss platform moving along the rails to pour concrete in each construction area. The size of the truss platform is limited by the rails on both sides, and the large bending moment in the middle of a large truss platform is not conducive to support by only the rails on both sides. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a prefabricated cross truss platform, which is conducive to forming the cross skeleton in the truss platform, facilitating assembly. After forming the cross skeleton first, other truss units are assembled one by one. Multiple cross truss platforms are arranged according to grid points, and then other truss platforms are assembled, as well as inserting members. This is conducive to building larger truss platforms, not being restricted by tracks, and avoiding the situation of excessive bending moment in the middle of large truss platforms.

[0004] To solve the above problems, a prefabricated cross-truss platform was adopted, which includes:

[0005] The branch truss platform assembly is arranged in a cross shape with left and right intervals and front and back intervals. It includes a top truss and early-release support steel columns fixed at the four corners of the top truss. The early-release support steel columns are fixed with sleeve buckles.

[0006] The interlocking truss platform assembly is disposed between spaced branch truss platform assemblies. It includes an interlocking truss and pin heads fixed to both ends of the upper and lower chords of the interlocking truss, with the pin heads inserted into the disc buckle.

[0007] With this structure, the branch truss platform components are connected by the interlocking truss platform components to form a cross shape, which helps to improve assembly efficiency. The pin head is inserted into the disc buckle, which facilitates the rapid assembly of the interlocking truss.

[0008] As a further improvement of this utility model, scissor bracing is provided between the upper and lower chords of the interlocking truss.

[0009] With this structure, the scissor bracing helps ensure the overall stability of the interlocking truss.

[0010] As a further improvement of this utility model, the scissor brace includes intersecting diagonal braces, with a first positioning sleeve sleeved in the middle of the diagonal brace, and a pin connecting two adjacent first positioning sleeves; lugs are hinged at both ends of the diagonal brace; the lugs are fixed on the second positioning sleeve, and the second positioning sleeve is slidably connected to the upper chord and the lower chord, and moves to a position close to the pin head.

[0011] With this structure, the two first positioning sleeves are connected by a pin and can rotate, which is beneficial for adjusting the distance between the upper and lower chords. This allows the pin head to flexibly insert into the disc buckle to accommodate disc buckles of different heights. After the second positioning sleeve slides, it can abut against the disc buckle, forming a clamping effect on the disc buckle. The disc buckle provides a limiting function, preventing the second positioning sleeve from sliding further, so that the scissor brace forms a stable structure.

[0012] As a further improvement of this utility model, a quick-release platform lifting mechanism is provided at the lower end of the early-release support steel column, and the quick-release platform lifting mechanism includes:

[0013] The steel frame foundation is assembled using Bailey bridges;

[0014] The support is removed and installed on the bottom surface of the middle part of the steel frame foundation;

[0015] The steel frame is installed on the top of the middle part of the steel frame support;

[0016] The first hydraulic jack is installed in the steel frame, with its bottom installed on the middle of the steel frame support platform, and its piston end is installed with the early dismantling support steel column.

[0017] The turbine screw jack is installed at the four corners of a steel frame support; the lower end of its lifting rod passes through the steel frame support and is fitted with positioning feet.

[0018] The drive wheel assembly is installed at the four corners of the steel frame platform and spaced apart from the lifting rod.

[0019] With this structure, the quick-release platform lifting mechanism is conducive to moving and lifting the branch truss platform components, and facilitates flexible assembly between the branch truss platform components.

[0020] This invention facilitates assembly. First, a cross-shaped frame is formed, and then other truss units are assembled one by one. Multiple cross-shaped truss platforms are arranged according to grid points, and then other truss platforms and insert members are assembled. This is conducive to building larger truss platforms, which are not limited by tracks, and avoids the situation of excessive bending moment in the middle of large truss platforms.

The pin head 202 is inserted into the disc buckle 103, which facilitates the rapid assembly of the interlocking truss 201.

[0039] In this embodiment, a scissor brace 203 is provided between the upper and lower chords of the interlocking truss 201.

[0040] With this structure, the scissor brace 203 helps to ensure the overall stability of the interlocking truss 201.
