Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to the technical field of embedded component protection devices, and specifically refers to a full-cycle protection device for embedded steel plates. Background Art

[0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roof engineering construction, decoration engineering construction, etc.

[0003] In the process of construction, embedded parts are often needed. Embedded parts are components that are pre-installed (buried) in concealed projects. They are components placed when the structure is cast and are used for overlap when building the upper structure to facilitate the installation and fixation of the foundation of external engineering equipment. Embedded parts are mostly made of metal, such as steel bars or cast iron, and can also be made of non-metallic rigid materials such as wood and plastic.

[0004] However, embedded parts are often damaged due to lack of protection during the construction process, so it is necessary to set up an embedded part protection device. For example, Chinese utility model patent ZL201921258752.2 discloses an embedded part protection device, including a protection device body, the protection device body includes an upper and lower layer of protection plates, the protection plates are staggered and stacked, and the two ends of the protection plates protrude downward to form a protection part. The protection plate is provided with a plurality of embedding holes, and the embedding holes are arranged on the lower side of the lower protective plate, located inside the protection part, and the steel bar sleeve of the embedded part is inserted into the embedding hole, and the protection device body is fixed to the steel cage. This embedded part protection device can increase the force-bearing area of the embedded part steel bar sleeve, strengthen the mechanical properties of the embedded part steel bar sleeve, and reduce the influence of external conditions on the embedded part steel bar sleeve, such as the influence of natural environment such as temperature and humidity, and play a protective role on the embedded part steel bar sleeve.

[0005] However, in actual use, when concrete is poured and vibrated, mortar may splash onto the embedded parts, which will affect the normal use of the embedded parts after solidification, and it is time-consuming and laborious to remove; if the embedded parts are to be welded with other components, the removal of unclean concrete slag and the scratches caused by the removal will affect the welding quality; if it is in a humid or even flooded environment for a long time after pouring, it will cause rust, which will also greatly affect the welding quality. In addition, the above embedded parts protection device is not suitable for protecting the embedded steel plates currently used in large quantities on construction sites.

[0006] Therefore, it is hoped to provide a full-cycle protection device for embedded steel plates, which can protect the embedded steel plates before concrete pouring, so that the embedded steel plates are protected throughout the entire cycle, are easy to disassemble, facilitate subsequent welding operations, save time and effort, and are reusable.
