an auxiliary baffle

Abstract

The invention provides an auxiliary baffle, comprising: a main baffle, an air duct and a funnel; an inner annular groove and an outer annular groove are arranged on the back of the main baffle; the inner annular groove and the outer annular groove are arranged between the inner annular groove and the outer annular groove There is an annular convex isolation belt; the top of the back of the main baffle is provided with a slot, which is respectively connected with the inner annular groove and the outer annular groove; the upper part of the main baffle is provided with a through hole, which is located inside the inner annular groove; The upper part of the front of the main baffle is provided with a blocking door; one side of the through hole is provided with a rotating shaft; the bottom end of the rotating shaft is fixedly connected with the front of the main baffle, and the top of the rotating shaft is rotatably connected with the blocking door; the discharge port of the funnel , for inserting into the through hole on the baffle of the main body; the air duct is used for inserting into the highest point of the top of the hole to be repaired through the outlet of the funnel and the through hole on the baffle of the main body. The application of the invention can greatly improve the work efficiency, improve the quality of on-site repair, and reduce the operation cost.

Description

technical field [0001] The present application relates to the technical field of civil engineering construction, in particular to a removable auxiliary baffle used for repairing a hole in a wall. Background technique [0002] When testing concrete components, the core drilling method is often used to sample the concrete components. Since the concrete member is a stressed member and needs to be sealed in the later stage, after sampling, filling materials with good fluidity (for example, grouting material, etc.) are mostly used on site to seal the sampling port. Under normal circumstances, it takes a long time for the filling material to solidify when closing the hole on site, and the whole plugging process is relatively slow due to the large amount of coring. [0003] In practice, in order to save manpower, the following methods are usually used: [0004] 1. Use mechanical means to block (for example, use expansion bolts to fix the cover plate for blocking).

Problems solved by technology

[0005] However, this method has the following problems: it is not conducive to maintaining the smoothness of the wall surface, and the expansion bolts cannot be removed, or the cracked surface formed after the expansion bolts are removed is relatively large

[0007] However, this method also has the following problems: it is difficult to dismantle after installation, it needs high temperature to dismantle, and the operation process is complicated and uneconomical

[0009] However, this method also has the following problems: the mixing of the quick-drying powder and the grout will affect the strength of the repair material, and the mixing ratio is difficult to control
