Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0025] Such as figure 1 Shown is the construction schematic diagram of the first-stage concrete structure and the second-stage concrete structure in the prior art. Among them, the first-stage concrete side wall 11 and the second-stage concrete slab 12 and beams are constructed step by step. When constructing the first-stage concrete side wall 11, it is necessary to pre-bury the second-stage concrete slab 12 and the ribs of the beam. Holes are punched on the formwork 13, and the steel bars directly pass through the wooden formwork 13; after the formwork is removed, the wooden formwork 13 cannot be reused, causing serious waste of timber, and the construction speed is slow, and the reinforcement of the wooden formwork 13 is complicated, which seriously affects the construction progress of the concrete structure.

The invention relates to a steel bar connecting sleeve for concrete construction and a construction process of the steel bar connecting sleeve. The steel bar connecting sleeve for concrete construction comprises a first steel bar body and a second steel bar body. A thread female head connecting sleeve of the first steel bar body is in threaded fit with a thread male head connecting sleeve of the second steel bar body. The steel bar connecting sleeve has the advantages that the construction process of the steel bar connecting sleeve for concrete construction is adopted, after the thread male head connecting sleeve of the second steel bar body is connected with the thread female head connecting sleeve of the first steel bar body through straight threads, the steel bar installing progress is accelerated, and the influence of joint bar installation on formworks is avoided; large turnup steel formworks can be used for a first-stage concrete structure, the construction progress of the first-stage concrete structure is effectively guaranteed, mutual interference of construction of the first-stage concrete structure and a second-stage concrete structure is relieved, the construction progress of the first-stage concrete structure and the second-stage concrete structure is greatly increased, and meanwhile the construction quality of the concrete structures is guaranteed.
Description
technical field [0001] The invention relates to the technical field of concrete construction, in particular to a steel bar connection sleeve for concrete construction and a construction process thereof. Background technique [0002] In the concrete construction of the existing hydropower plant building, according to the structural characteristics of the hydropower plant, the first-stage concrete side walls and the internal second-stage concrete slabs and beams are constructed separately. Inserting bars, the existing technology is generally to punch holes in the formwork, and the steel bars pass directly through the formwork. Because the steel formwork is difficult to remove, most of the wooden formwork is used, and the wooden formwork cannot be reused after each formwork removal, resulting in serious wood damage. It is wasteful, and the construction speed is slow, and the formwork reinforcement is complicated, which seriously affects the concrete construction progress of the...
