Description

TECHNICAL FIELD

[0001] The utility model relates to pre -buried connecting piece technical field, concretely is a curtain wall pre -buried connecting piece. BACKGROUND

[0002] The curtain wall is the outer wall of the building, which is composed of a plate and a supporting structure system. The curtain wall has a certain displacement capacity relative to the main structure or a certain deformation capacity itself. The curtain wall is a building outer envelope structure or a decorative structure that does not bear the action of the main structure. Before installation, a pre-buried connecting piece is usually embedded between the cast concrete to facilitate later installation and ensure the stability of the curtain wall after installation.

[0003] In order to facilitate the use of the pre-buried connecting piece to install the curtain wall later, the prior art has made many improvements to the curtain wall pre-buried connecting piece. For example, the patent with the publication number CN217924136U discloses a curtain wall pre-buried connecting piece, which includes a mounting seat, a pre-buried rod, a mounting slot, and a mounting plate. It also includes an adjusting device. The pre-buried rod is fixedly connected to the surface of the mounting seat. The mounting slot is provided on the surface of the mounting seat. The mounting plate is provided on the surface of the mounting slot. The adjusting device is provided on the surface of the mounting slot. The adjusting device includes a toothed plate, which is fixedly connected to the surface of the mounting plate. The toothed plate is slidingly connected to the inner wall of the mounting slot. The surface of the mounting slot is rotatably connected to a gear. The gear is meshingly connected to the surface of the toothed plate. The utility model, by setting the adjusting device, facilitates the adjustment of the mounting plate, avoids the displacement of the mounting plate from the pre-buried location due to extrusion after the completion of concrete pouring, and thus affects the subsequent installation and connection of the mounting plate. This effectively improves the ease of use of the equipment.

[0004] The above-mentioned patent has obvious beneficial effects, but still has the following deficiencies in real operation:

[0005] In the above-mentioned comparative document, the position of the mounting plate can be adjusted by the adjusting device. In reality, concrete pouring can not only cause the left and right displacement of the pre-buried connecting piece, but also can cause the up and down displacement of the pre-buried connecting piece. The above-mentioned comparative document can only adjust the mounting plate left and right. If the pre-buried connecting piece is displaced upward, the angle steel connecting piece used to connect the mullion cannot be connected to the reserved position of the mullion after being connected to the pre-buried connecting piece, which causes inconvenience in installing the mullion. Therefore, there is an urgent need in the field to improve the curtain wall pre-buried connecting piece to solve the defects of the prior art. UTILITY MODEL CONTENTS
