Description

Technical Field

[0001] The utility model relates to the field of electromechanical installation and construction, in particular to a coaxial positioning device for a wall-penetrating sleeve without blocking. Background Art

[0002] Mechanical and electrical installation construction often encounters a large number of wall-penetrating construction. When the casing is constructed according to the traditional process and then the wall-penetrating pipe is constructed, the gap between the wall-penetrating pipe and the peach trunk is small, and the wall-penetrating pipe cannot be effectively fixed. Often during the pipe-penetrating construction, the wall-penetrating pipe is basically placed at the bottom of the casing, and the construction requirements of concentricity and coaxiality of the wall-penetrating casing and the wall-penetrating pipe cannot be achieved, and the quality control of fireproof sealing is difficult, and other technical defects. Summary of the invention

[0003] The utility model aims to provide a coaxial positioning device for wall bushings without blocking, so as to solve the technical defects in the field of electromechanical installation construction that the wall bushings and wall pipes cannot be coaxial and concentric, and the quality control of fire blocking is difficult.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A coaxial positioning device for a wall-penetrating sleeve without blocking comprises a wall-penetrating sleeve, a positioning steel bar, a galvanized iron sheet pipe, fireproof mud and a wall-penetrating pipe;

[0006] The sum of the length of the positioning steel bar and the thickness of the galvanized iron sheet is equal to half of the difference between the inner diameter of the wall sleeve and the outer diameter of the wall pipe;

[0007] The positioning steel bars are vertically welded to the outer surface of the galvanized iron pipe;

[0008] The galvanized iron pipe welded with positioning steel bars is placed in the wall sleeve;

[0009] Fireproof mud is filled between the inner wall of the wall sleeve and the galvanized iron pipe.

[0010] Compared with the prior art, the beneficial effect of the present invention is that the application of the coaxial positioning device can realize the accurate positioning of the wall-penetrating pipe, greatly reducing the error problem existing in the electromechanical installation construction process, thereby ensuring the construction quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a schematic diagram of the overall structure of a coaxial positioning device for a wall-penetrating sleeve without blocking described in the utility model;

[0012] In the picture: 1 wall sleeve, 2 galvanized iron pipe, 3 fireproof mud, 4 positioning steel bars. DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] like Figure 1 As shown, a blockage-free wall-penetrating sleeve coaxial positioning device comprises a wall-penetrating sleeve 1, a positioning steel bar 4, a galvanized iron sheet pipe 2, fireproof mud 3 and a wall-penetrating pipe;

[0015] The sum of the length of the positioning steel bar 4 and the thickness of the galvanized iron sheet is equal to half of the difference between the inner diameter of the wall sleeve 1 and the outer diameter of the wall pipe;

[0016] The positioning steel bars 4 are vertically welded to the outer surface of the galvanized iron tube 2;

[0017] The galvanized iron pipe 2 welded with the positioning steel bar 4 is placed in the wall sleeve 1;

[0018] Fireproof mud 3 is filled between the inner wall of the wall bushing 1 and the galvanized iron pipe 2 .

[0019] During the construction process, the coaxial positioning device for the wall-penetrating sleeve that does not require blocking is directly placed on the wall and the masonry or concrete pouring of the wall is completed. During the later mechanical and electrical installation construction, the wall-penetrating pipe is directly inserted into the coaxial positioning device for the wall-penetrating sleeve that does not require blocking. The wall-penetrating pipe and the wall-penetrating sleeve can be made concentric and coaxial, and secondary fireproof blocking is eliminated, thereby effectively improving the construction quality.

[0020] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Simple modifications or equivalent substitutions of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
