Description

Technical Field

[0001] This utility model belongs to the technical field of water tank roof construction for water supply and drainage engineering, and specifically relates to a water tank roof splicing device. Background Technology

[0002] Cast-in-place concrete water tank construction is a common technique in current water tank construction, characterized by high strength, strong waterproofing, simple construction, and low cost. Therefore, it has been widely used in the construction of large water tanks in some factories. However, the traditional cast-in-place process with a full-span scaffolding system for the water tank roof has low construction efficiency, involves a large amount of formwork erection and dismantling work, and is not conducive to controlling the construction schedule. Furthermore, the working environment is limited, posing certain safety hazards, and the quality control of cast-in-place thin slabs is quite difficult. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a water tank top panel splicing device to overcome the shortcomings of the prior art.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A water tank roof slab splicing device is provided, comprising a UHPC+RC precast roof slab, an anchoring structure, and a post-cast reinforced concrete structure. The anchoring structure is disposed at the end of the UHPC+RC precast roof slab. The UHPC+RC precast roof slab rests on the cast-in-place tank wall and bottom beam. A single-layer bidirectional steel mesh is provided on the upper part of the UHPC+RC precast roof slab to form an integral structure with the anchoring structure. The post-cast reinforced concrete structure is formed after the UHPC+RC precast roof slab infill, integral concrete surface layer, and connection nodes are poured, so that adjacent UHPC+RC precast roof slabs are stably spliced ​​together.

[0006] As described in the water tank top slab splicing device, the UHPC+RC precast top slab is a ribbed slab. The structure of the UHPC+RC precast top slab from bottom to top consists of a 10mm thick UHPC solid slab layer, a 40mm thick C30 precast reinforced concrete solid slab layer, a 50mm thick UHPC shear layer, and a 50mm thick UHPC rib layer. Post-cast concrete fills the gaps between the ribs of the ribbed slab.

[0007] As described in the pool top slab splicing device, the anchoring structure is located within the post-cast connection groove, and the anchoring structure is encased within the post-cast concrete.

[0008] As described in the pool top slab splicing device, the anchoring structure includes pre-embedded anchor bars and pre-embedded reinforcing bars in a 40mm thick C30 precast reinforced concrete solid slab. The pre-embedded anchor bars are pre-embedded in the cast-in-place pool wall and the top of the bottom beam. After the pre-embedded reinforcing bars in the 40mm thick C30 precast reinforced concrete solid slab are lapped and connected with the pre-embedded anchor bars, the connection node concrete is poured.

[0009] As described in the pool top slab splicing device, the anchoring structure includes pre-embedded anchor bars and UHPC+RC precast top slab post-tied steel bars. The pre-embedded anchor bars are pre-embedded in the cast-in-place pool wall and the top of the bottom beam. The UHPC+RC precast top slab post-tied steel bars are lapped and connected to the pre-embedded anchor bars, and then the connection node concrete is poured.

[0010] The beneficial effects of this utility model's technical solution are:

[0011] It can significantly improve construction efficiency, reduce the workload of erecting and dismantling formwork and supports for the construction of the top slab structure, avoid the safety risks of working in confined spaces, and ensure the construction quality of the connection nodes after hoisting the components as a whole. It has good applicability and economy. Attached Figure Description

[0024] Furthermore, the anchoring structure 3 includes pre-embedded anchor bars and post-tied reinforcing bars of the UHPC+RC precast top slab. The pre-embedded anchor bars are pre-embedded in the top of the cast-in-place pool wall and bottom beam 1. After the post-tied reinforcing bars of the UHPC+RC precast top slab are lapped and connected with the pre-embedded anchor bars, the connection node concrete is poured to achieve a reliable connection between the UHPC+RC precast top slab 2 and the cast-in-place pool wall and bottom beam 1.
