Embodiment 1

[0025] For the bolted embedded parts in Embodiment 1, refer to the performance of the connection node between the SP prestressed hollow slab and the steel structure in the National Standard Atlas, at least two embedded parts are prefabricated at one end of the SP slab, and M16 high-strength nuts 3 are used to secure the building The (wall) panel is connected to the steel structure 6 . The production of SP prestressed hollow slabs is the same as the original process, only welding nuts are added to the original embedded parts.

[0026] Based on the same principle, as figure 2 As shown, Embodiment 2 provides another SP prestressed hollow slab with bolted embedded parts, which includes a conjoined bolted embedded part 7, and the length of the connected bolted embedded part 7 is the same as that of the The width of the SP prestressed hollow slab is suitable, and the connected bolted embedded part 7 has the same number of buckle and anchor hooks as the main ribs of the SP prestres...

Embodiment 2

[0030] In Example 2, each steel strand (main reinforcement) of the SP prestressed hollow slab is connected to the steel beam through bolted embedded parts and high-strength nuts, effectively ensuring the integrity of the connection between the prestressed floor slab and the steel beam. Applying the bolted embedded parts of this case in the manufacture of prefabricated prestressed concrete slabs will improve the reliability of the connection between the main reinforcement of the slab and the beam, and expand the application field of prefabricated prestressed floor (wall) slabs.

[0031] Embodiment 2 A conjoined embedded part can be further placed at the end of the SP prestressed hollow slab with a length close to the width of the prefabricated slab, and the embedded parts buckle and anchor all the steel strands (main bars) in the concrete prestressed slab. The floor (wall) boards installed on site are connected with high-strength nuts in turn, so that all steel strands (main bar...

Abstract

The invention relates to an SP prestressed hollow slab with bolting embedded parts, which is connected with a steel structure. At least two monomer bolting embedded part or a combined bolting embedded part is arranged in the position of the connecting node of the SP prestressed hollow slab and the steel structure, each monomer bolting embedded part is used for fastening and anchoring one main bar of the SP prestressed hollow slab, the combined bolting embedded part is used for fastening and anchoring all main bars of the prestressed hollow slab, and nuts are welded on the monomer bolting embedded parts or the combined bolting embedded part and used for connecting the steel structure. The bolting embedded parts are connected with the steel structure through the high-intensity nuts, the quality is stable and reliable, when the SP prestressed hollow slab adopting the bolting embedded parts is manufactured in a factory, the main bars in the SP prestressed hollow slab and the bolting embedded parts are fastened and anchored, only assembling and bolting with beams are required in field installation, assembling and adjusting are convenient and reliable, and the earthquake resistant behavior of a building structure can be improved effectively.

Description

technical field [0001] The invention relates to the application field of SP prestressed hollow slabs, in particular to an SP prestressed hollow slab with bolted embedded parts. Background technique [0002] "SP prestressed hollow slab" (may be referred to as "SP slab" for short) is a prefabricated component used for floor and wall panels in building structures. When SP prestressed hollow slabs are connected to the structural nodes of steel structures (steel columns, steel plates, steel beams, etc.), most of them use lap joints or welded with embedded parts. On-site welding of embedded parts and steel structures requires on-site power supply, which is inconvenient. If open flames are not allowed to be used during construction and installation, the floor cannot be welded. Especially when installing wall panels, it is difficult to align the welding operation during the installation process, and the overlapping welding section between the embedded parts and the steel beams is s...
