Novel concrete embedded bolt mechanism and using method thereof

Abstract

The invention relates to the technical field of embedded bolts, and discloses a novel concrete embedded bolt mechanism. The mechanism comprises a connecting rod and an extension rod. The right end ofthe connecting rod is in threaded connection with the left end of the extension rod. A screw thread is arranged at the exterior of the right end of the extension rod. The exterior of the right end ofthe extension rod is in threaded connection with a nut matched with the screw thread. A T-shaped fixing piece is installed at the right end of the extension rod. A plastic fitting matched with the nutis fixedly connected to the left end of the T-shaped fixing piece. The nut is sleeved with the plastic fitting. A screw cap is in threaded connection with the exterior of the left end of the connecting rod. According to the novel concrete embedded bolt mechanism and the using method thereof, when construction is performed on N layers, a combination component composed of a T-shaped embedded pieceand a nut plastic fitting of an embedded bolt is embedded at the outer side of the upper portion of a concrete shear wall in advance, when the (N+1)th layer formwork is reinforced, one piece of steeltube support is added to the position of the embedded bolt, and the (N+1)-layer concrete shear wall integrated wood formwork reinforcing quality is ensured.

Description

technical field [0001] The invention relates to the technical field of pre-embedded bolts, in particular to a novel concrete pre-embedded bolt mechanism and a method for using the same. Background technique [0002] Most of the construction projects now are reinforced concrete structures, and whoever can complete the construction of the main structure of the construction project with better quality and efficiency in today's society will be invincible in the construction industry. The current mainstream reinforced concrete main structure construction method still uses wooden formwork as the main formwork system for the construction of the main structure. Using wooden formwork for construction has many advantages, such as: 1. Tradition, good market acceptance, construction does not require training, 2. Assembly It is convenient and requires few accessories for assembly. 3. The cost of a single sheet is low, suitable for no need for turnover projects. 4. It can be mixed with ...

Problems solved by technology

[0004] Aiming at the deficiencies of the existing technology, the present invention provides a new type of concrete pre-embedded bolt mechanism and its use method, which has the advantages of ensuring construction quality, avoiding problems such as film bursting and mold expansion, and solves many problems caused by wooden formwork construction: 1. The reinforcement forms of the wood formwork erection system are often various and complicated. When the wood formwork is reinforced, the overall reinforcement quality is also uneven due to the different techniques of each reinforcement worker. There are good and bad.

In the later stage, it is easy to miss inspection and missed inspection, which often leads to the problem of mold explosion due to the weak reinforcement of the formwork system in the process of concrete pouring in the later stage.

2. At the same time, due to the small rigidity of the wooden formwork material, it is easy to deform after many turnovers, and the position that is not reinforced after pouring concrete is easy to cause quality problems such as mold expansion
