Description

Technical Field

[0001] The utility model relates to the technical field of grouting hole forming for precast wall panels, and specifically relates to a fixing device applicable to the forming of grouting holes for precast wall panels. Background Technique

[0002] With the continuous development of the construction engineering industry, precast wall panels have been widely used due to their characteristics such as fast installation and simple construction technology. In order to improve the seismic resistance, durability and compactness of the wall panels, it is necessary to carry out grouting treatment inside them.

[0003] At present, magnetic bases are usually embedded in the grouting holes, but the magnetic bases have high losses and high unit prices, which is not conducive to controlling production costs. Moreover, during the production process of the grouting bellows, it is easy to be fixed unstably and fall off, resulting in quality defects such as grouting hole blockage. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to provide a fixing device applicable to the forming of grouting holes for precast wall panels.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A fixing device applicable to the forming of grouting holes for precast wall panels, including a fixed base, a taper sleeve is connected above the fixed base, a fixing bolt is arranged inside the taper sleeve, and a flat head nut is connected to the bottom of the fixing bolt.

[0007] Further, the fixed base is a frustum, an annular buffer layer is fixedly connected inside the fixed base, and the bottom of the taper sleeve is fixedly connected to the top of the fixed base.

[0008] Further, a reserved groove is formed inside the taper sleeve, and the reserved groove penetrates downward through the top of the fixed base.

[0009] Further, threads are provided on the inner surface of the reserved groove, and the fixing bolt is threadedly connected to the inner surface of the reserved groove.

[0010] Further, the lower part of the fixing bolt is threadedly connected to the inner surface of the flat head nut.

[0011] Further, the end of the flat head nut is welded to the positioning point of the grouting hole.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] Through the positioning of the fixed base, the slurry outlet hole and the grouting hole are on the same horizontal line, and the circular taper sleeve is convenient for controlling the appearance quality of the hole after demoulding;

[0014] The pre-embedding of the grouting magnetic base is eliminated, reducing production costs;

[0015] The taper sleeve locking design can effectively fix the grouting bellows, ensuring that it is not easy to fall off during the production process. Description of the Drawings

[0016] The drawings are used to provide a further understanding of the present invention and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation to the present invention.
