A kind of decorative fair-faced concrete electric pre-embedded box and its construction method

Abstract

The invention discloses a veneer bare concrete electric pre-buried box. The veneer bare concrete electric pre-buried box includes a box body and a formwork, the box body is provided with a conduit connection, a first through hole is formed in the bottom of the box body, the bottom surface of the formwork is symmetrically provided with two support plates, the bottom portions of the support plates are provided with notches, the center of the formwork is provided with a second through hole, fixed bolts penetrate through the second through hole and the first through hole to be connected with a nutand further to fix the formwork to the box body, the fixed bolts are in interference fit with the notches, and when the fixed bolts are inserted in the box body in a connected mode, the fixed bolts can push the support plates to mutually crimp the inner wall of the box body; and the edge of the bottom surface of the formwork is provided with a groove, and the top edge of the box body is insertedin the groove in a connecting fit mode. According to the veneer bare concrete electric pre-buried box and the construction method thereof, shortage of the existing technology can be improved, the construction complexity of an electric pre-buried box is simplified, and the protection for veneer bare concrete wall surface can be improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an electric pre-embedded box of facing fair-faced concrete and a construction method thereof. Background technique [0002] Finished fair-faced concrete refers to the fair-faced concrete whose surface color is basically the same, which is formed by a combination of regularly arranged bolt holes, open seams, cicada seams, false eyes, etc., and has a natural texture as the finishing effect. The concrete poured by this process utilizes the apparent characteristics of the concrete itself to achieve decorative visual effects. The concrete surface has a dense appearance, consistent color tone, and less air bubbles. [0003] The main characteristics of the facing clear-water concrete structure are: it is formed once in the construction of the clear-water concrete structure, no decoration is required, construction methods such as coatings and finishes are omitted, and the p...

Problems solved by technology

[0004] The existing electrical pre-embedded box needs to be repaired and chiseled at the edge after the wall is poured. In order to ensure that the pre-embedded box does not deform during the pouring process, it is necessary to add fillers to the pre-embedded box. After pouring The filling needs to be cleaned, which is not only time-consuming, but also easily pollutes the finished fair-faced concrete
