Technical Field

[0001] The present application relates to the technical field of building materials, and in particular to a large-span assembled prefabricated panel. Background Art

[0002] Precast panels are the floor panels used in early 20th century buildings, which are the modules or panels used in engineering. They are called precast panels because they are prefabricated concrete parts produced and processed in the prefabrication site and transported directly to the construction site for installation.

[0003] At present, general prefabricated panels are usually made by first nailing a hollow model with wooden boards, distributing steel bars in the hollow part of the model, filling the hollow part with cement, and knocking off the wooden boards after drying, and what remains is the prefabricated panel.

[0004] However, during the installation process, since it is difficult to align the steel bars, proofreading can only be done manually, which is time-consuming and labor-intensive and reduces installation efficiency. Utility Model Content

[0005] In order to improve the installation efficiency of prefabricated panels, the present application provides a large-span assembled prefabricated panel.

[0006] The present application provides a large-span assembled prefabricated panel, which adopts the following technical solution:

[0008] By adopting the above technical solution, during the installation of the prefabricated panels, the detection component locates the position of the steel bars, and then the steel bars are inserted into the pressure-resistant hole grooves, the steel bars are squeezed with the fixing component, the fixing component clamps the steel bars, and under the action of the thrust of the steel bars, the reinforcement component fixes the fixing component and the prefabricated panel body, so that multiple prefabricated panel bodies can be firmly spliced;

[0009] After the splicing is completed, the bracket is installed on the prefabricated panel body. By setting prestressed cables, prestress can be applied to the prefabricated panel under the support of the bracket, so that multiple prefabricated panels can form a whole after assembly, thereby enhancing the integrity and stability of the structure, making it easier for operators to install the prefabricated panels, thereby improving the installation efficiency of the prefabricated panels.

[0010] Optionally, a storage groove is expanded at the notch of the pressure-resistant hole groove, and the detection assembly includes a slide cylinder and an extrusion spring, the slide cylinder is slidably connected in the pressure-resistant hole groove, and the sliding direction is the same as the axial direction of the pressure-resistant hole groove; the end of the slide cylinder close to the notch of the pressure-resistant hole groove is stepped and adapted to the storage groove; a retreat groove is opened on the bottom of the storage groove, and the two ends of the extrusion spring are respectively fixedly connected to the bottom of the retreat groove and the stepped side of the slide cylinder, the extrusion spring is in a stretched state in the initial state, and the axial direction of the extrusion spring is arranged parallel to the axial direction of the pressure-resistant hole groove.

[0011] By adopting the above technical solution, since the extrusion spring is in a stretched state in the initial state, the step side of the slide tube slides out of the storage groove under the elastic force of the extrusion spring, so that the steel bars can easily enter the slide tube when the prefabricated plate is dropped and placed;

[0012] In addition, when the steel bar is inserted into the slide, the steel bar will squeeze the slide and cause it to move along the axial direction of the pressure-resistant hole groove. The movement of the slide will compress the extrusion spring. By monitoring the compression degree of the extrusion spring or the moving distance of the slide, the insertion depth of the steel bar can be indirectly judged, thereby facilitating dynamic monitoring of the steel bar position.

[0013] Optionally, the fixing assembly includes a fixing platform, a top cover and multiple groups of supporting parts, the fixing platform is arranged around the axial direction of the slide cylinder and fixedly connected to the inner wall of the slide cylinder; the top cover is hinged to the slide cylinder through multiple groups of supporting parts; multiple groups of supporting parts are arranged around the axial direction of the slide cylinder, the supporting parts are arranged on the slide cylinder, and are used to transmit the thrust exerted on the top cover to the slide cylinder.

During the movement, the sliding rod moves in the slide groove due to the squeezing force of the top cover, and the sliding rod drives the rotating rod to rotate. When the rotating rod rotates to a horizontal position, the fixed platform blocks the rotation trend of the rotating rod, and the rotating rod squeezes the fixed platform, which drives the slide cylinder to move, thereby facilitating the reset of the slide cylinder and further facilitating the installation of the prefabricated panels.

[0018] Optionally, the reinforcement assembly includes a fixed block and multiple groups of reinforcement parts, the fixed block is fixedly connected to one end of the slide cylinder away from the storage groove; a plurality of matching grooves are opened on the side wall of the pressure-resistant hole groove close to the groove bottom, and the multiple matching grooves are arranged around the axial direction of the pressure-resistant hole groove; multiple groups of reinforcement parts are arranged around the axial direction of the slide cylinder, and correspond one by one to the multiple matching grooves, the reinforcement parts are arranged in the pressure-resistant hole groove, and are used to enhance the connection strength between the slide cylinder and the prefabricated plate body.
