Embodiment Construction

[0031] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] This embodiment proposes a precise pre-embedded device for the reserved holes of the concrete movable cover plate, including a round steel pre-embedded device 3 and a galvanized steel pipe connector 4 . Among them, such as Figure 4 As shown, the round steel pre-embedded device 3 is made of round steel. Its size and specification can be adjusted according to the actual situation. Easy to operate and can be used repeatedly. Such as Figure 5 and 6 As shown, the galvanized steel pipe connector 4 is made of galvanized steel pipe, and its pipe diameter is one specification larger than the round steel. The two ends of the connector 4 can be inserted into two round steel pre-embedded devices 3 . The length of the g...

Abstract

The invention provides a device for precisely embedding a concrete movable cover plate in a reserved hole and an installing and using method thereof. The precise embedding device comprises embedding device bodies and a connector. The embedding device bodies are used for being inserted into concrete before the concrete is primarily set. The connector is used for connecting the embedding device bodies so that the distance between every two embedding device bodies can be controlled and the reserved hole can be accurately located. The size, specification and model number of the embedding device bodies can be adjusted according to the actual situation, the precise embedding device is embedded and pulled out as a whole before the concrete is primarily set, and the locating precision of the reserved hole can be effectively improved. The pipe diameter of the connector is one specification larger than the diameter of the embedding device bodies, and inserting and pulling are facilitated. The length of the connector can be freely adjusted according to the actual locating size of the reserved hole. The diameter of the embedding device bodies and the diameter of the connector can be flexibly changed according to the design requirement of the cover plate, and the distance of the reserved hole can be freely changed. The embedding device bodies and the connector are detached before the concrete is finally set, the precise embedding device can be recycled, and recycling materials are saved.

Description

technical field [0001] The invention belongs to the technical field of concrete pouring, and in particular relates to a precise pre-embedding device for reserved holes of a concrete movable cover plate and an installation and use method thereof. Background technique [0002] In the civil engineering industry, although the prefabrication of reinforced concrete movable cover slabs has always occupied a small proportion, and the pre-embedding of the reserved holes occupies an even smaller proportion, but the existing technology has not found a better method for the precise pre-embedding of the reserved holes. , often after the reinforcement of the reinforced concrete movable cover slab is bound and the formwork is installed, the PVC pipe is temporarily pre-buried before the concrete is poured, and the PVC pipe is directly buried or pulled out after the concrete is poured. [0003] Such as Figure 1~3 As shown, according to the existing technical situation and the fact that the ...
