Description
Technical Field
The present invention relates to an embedded part, a concrete prefabricated part with the embedded part, a dry-hang system and an embedding method of the embedded part, and more particularly, to an embedded part, a concrete prefabricated part with the embedded part, a dry-hang system and an embedding method of the embedded part, which make the assembly and installation of the concrete prefabricated part easier.
Background
In the existing concrete processing, embedding and mounting technology, one end of a common steel bar is embedded in the concrete which is not dried, and the other end of the common steel bar is welded on an auxiliary steel frame to assemble the concrete prefabricated part. Various fasteners or connectors (also known as embedments) are used to secure, assemble, and hang various portions of the building.
However, in the pre-burying process, specifically, under the condition that the pre-burying method in the prior art is adopted to pre-bury the pre-buried part, when different pre-burying personnel pre-bury the concrete, the pre-burying depth and the pre-burying position cannot be controlled, and an unexpected difference is invisibly increased, so that the quality of the whole concrete building is unstable. For example, some pre-burying workers place the embedded parts deep, some pre-burying workers place the embedded parts shallow, and different operations lead to different pre-burying depths of the embedded parts.
Furthermore, when the prefabricated parts of a concrete building (for example, two pieces of concrete) are installed, the fixing parts of the fastening members or the connecting members in the prior art undesirably slide or twist, so that the installation result is unsatisfactory, and even a safety problem occurs.
In addition, because the structural member with one end welded is embedded in one end in the prior art, high temperature is transferred to the precast concrete member in the welding process, and the precast concrete member is easy to crack.
In addition, in the case of installing the concrete prefabricated parts in the prior art, there is no appropriate way to hang the two prefabricated parts. For example, in the case of a long precast concrete member, if the precast concrete member is too long, it is not easy to transport and it is also not easy for an installer to install, and at this time, it is necessary to properly hook the embedded parts for hooking.
Further, even if the hitching member is buried in advance, if the burying position of the hitching member is not reasonable, it is difficult to perform the installation and cutting, thereby causing inconvenience to the installer. For example, in the process of installing concrete prefabricated parts, it is often necessary to cut the concrete prefabricated parts to a desired size for use. Therefore, how to better carry out hanging connection and connection on the cut concrete prefabricated parts is also a technical problem which needs to be solved urgently. In addition, when various concrete building members are installed by using various members in the prior art, different installers have great difference in assembly results, uniform and safe installation results are difficult to obtain, and the safety problem caused by high temperature transmission to the concrete members cannot be solved.
