Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a support-free device for primary and secondary beams of assembled prefabricated components. Background Art

[0002] With the rapid development of prefabricated projects, prefabricated buildings have been widely used in housing construction projects, and prefabricated buildings are also a trend in the future development of the construction industry. After being produced in the factory, prefabricated components are transported to the site for hoisting, and the nodes and superposition layers are poured to complete a prefabricated structure. Prefabricated buildings are more environmentally friendly than traditional reinforced concrete buildings. However, during the construction process, scaffolding still needs to be set up to support the prefabricated primary and secondary beams. The scaffolding can only be removed after the concrete strength meets the specification requirements. A large amount of scaffolding and labor are still required, the construction cost is high, and the construction period is also long.

[0003] Therefore, it is necessary to propose a support-free device for primary and secondary beams of assembled prefabricated components to solve the above problems. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a support-free device for primary and secondary beams of assembled prefabricated components, which does not require the construction of scaffolding to support the prefabricated primary and secondary beams, thereby saving labor and construction time, and thus saving costs.

[0007] Furthermore, the two first steel members in the first steel member group are fixedly mounted on the main beam by means of tension screws.

[0008] Furthermore, the main beam is provided with three reserved holes arranged in parallel along the vertical direction, and the first steel member is provided with three first mounting holes corresponding to the reserved holes one by one, and three tension screws respectively pass through the first mounting holes and the reserved holes to fix the two first steel members on the opposite side walls of the main beam.

[0009] Furthermore, the I-beam is arranged in an I-shape, and the I-beam is fixedly connected to the four first steel components by bolts respectively.

[0010] Furthermore, the second steel member is installed on the side of the first steel member away from the main beam.

[0011] Furthermore, a rubber gasket is installed on the top wall of the second steel member.

[0012] Furthermore, a second mounting hole corresponding to the first mounting hole is provided on the second steel member, and the second steel member is fixedly mounted on the first steel member by means of a tension screw, wherein the second mounting hole on the second steel member corresponds to the first mounting hole located at the bottom on the first steel member.

[0013] The beneficial effects of the utility model are:

[0014] The utility model installs the first steel member group, the I-beam and the second steel member on the prefabricated main beam, and uses the second steel member to support the prefabricated secondary beam, so that the bottom of the beam slab does not need to be supported by scaffolding, thereby saving a large amount of scaffolding materials, saving labor and construction period, and thus saving costs; and the support-free device is easy to disassemble for turnover use.
