DETAILED DESCRIPTION

[0025] 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.

[0026] See also Figure 1-4 A pre-buried casing for building water supply and drainage comprises a pre-buried casing mechanism 1, both ends of the pre-buried casing mechanism 1 are equipped with auxiliary support mechanisms 2, and the stability of the pre-buried casing mechanism 1 is maintained by fixing the auxiliary support mechanism 2 to a fixing surface;

[0027] The embedded casing mechanism 1 comprises an embedded casing body 101 embedded in the facade, and both ends of the embedded casing body 101 are provided with extension joints 102, and the extension joints 102 extend to the outside of the facade;

[0028] The auxiliary support mechanism 2 includes a sleeve 201, one end of which is plugged into the extension joint 102, and the other end of the extension joint 102 is plugged into the water pipe. A limiting groove 202 is provided on the outer surface of the sleeve 201, and a fixing device 203 is installed on the outer surface of the limiting groove 202. The fixing device 203 is fixedly connected to the ground or the embedded inside to support the sleeve 201.

[0029] Through the above technical solution, an extension joint 102 is provided at the end of the embedded sleeve body 101 to connect the sleeve tube 201, and a limiting groove 202 is provided on the sleeve tube 201 to limit the fixing device 203. At the same time, the position of the embedded sleeve body 101 is fixed by the fixing piece in cooperation with the fixing device 203, so that the embedded sleeve body 101 will not be displaced due to backfilling, concrete pouring and other operations after being embedded, thereby achieving the effect of improving the installation stability of the embedded sleeve.

[0030] Specifically, the outer surface of the embedded casing body 101 is fixedly connected with anchors 103, and the anchors 103 are arranged equidistantly around the circumference.

[0031] Through the above technical solution, the purpose of setting the anchor 103 on the outer surface of the embedded sleeve body 101 is to enhance the friction and adhesion of the outer surface of the embedded sleeve body 101, so that after backfilling or concrete pouring, the embedded sleeve body 101 can be more stably located in the vertical surface formed after backfilling or concrete pouring, and will not be easily pulled out.

[0032] Specifically, the anchor 103 is made of metal, and the outer surface of the anchor 103 is arc-shaped, with hooks formed at both ends of the arc.

[0033] Through the above technical solution, the purpose of setting the anchor 103 to be a metal material is to improve the firmness. The anchor 103 can also be made of other rigid materials, and hooks are formed at both ends of the outer surface of the anchor 103, so that it can form a gripping force with the inside of the facade formed after backfilling or concrete pouring, which can further prevent the embedded sleeve body 101 from displacement. Specific implementation method 1

[0035] The limiting groove 202 is a central groove 202a, and the fixing device 203 includes a clamp 2031a, which is installed in the central groove 202a, and a support frame 2032a is fixedly connected to the side of the clamp 2031a.

[0036] Through the above technical solution, the limiting groove 202 is set as the central groove 202a, the purpose of which is to limit the clamp 2031a to prevent the clamp 2031a from sliding, and the support frame 2032a is used to support the sleeve tube 201, so that the height and position of the embedded sleeve body 101 are maintained through the cooperation between the sleeve tube 201 and the extension joint 102 to avoid misalignment.

[0037] Specifically, a support foot is provided at the bottom of the support frame 2032a, and a through hole is opened on the support foot. The through hole is used to penetrate a fastener to connect and fix with the ground.

[0038] Through the above technical solution, a support foot is set at the bottom of the support frame 2032a to increase the supporting area, and the sleeve tube 201 is further positioned by opening a through hole on the support foot to pass bolts, rivets and other fixable structures to improve the stability of the embedded sleeve body 101. Specific implementation method 2

[0040] The limiting groove 202 is a through groove 202b, and the fixing device 203 includes a connecting ring 2031b. The side circumference of the connecting ring 2031b is distributed with an oblique support frame 2032b.

[0041] Through the above technical solution, the limiting groove 202 is set in the style of a through groove 202b, so that the connecting ring 2031b can be directly inserted into the sleeve tube 201, which can reduce the fixing steps, and the purpose of setting the inclined support frame 2032b is to be able to locate the height of the connecting ring 2031b from the side and prevent the connecting ring 2031b from sliding in the through groove 202b;

[0042] The connection ring 2031b and the inclined support frame 2032b are matched, and the inclined support frame 2032b is fixedly connected to the facade, so that the stability of the embedded casing body 101 can be ensured when the embedded casing body 101 is suspended, because the embedded casing is not necessarily installed close to the ground or embedded in the ground;

[0043] The purpose of providing a plurality of inclined support frames 2032b arranged in a circular array is to increase the support points and thus improve stability;

[0044] The recommended usage scenario is that after the carpenters have supported the formwork, the embedded sleeve body 101 is placed between the formworks, and the extension joint 102 extends out of the formwork, and then is connected and fixed to the outer surface of the formwork through the inclined support frame 2032b, so that when pouring concrete in the formwork, it can be ensured that the position of the embedded sleeve body 101 will not be displaced or changed.

[0045] Specifically, a support foot is provided at the end of the inclined support frame 2032b, and a through hole is opened on the support foot. The through hole is used to penetrate a fastener to connect and fix with the facade.

[0046] Through the above technical solution, the purpose of setting a support foot at the end of the inclined support frame 2032b is also to increase the contact area, and the through hole set on the support foot is also to facilitate fixation. The sleeve 201 is kept perpendicular to the facade by inclined pulling, and the installation position is ensured to remain unchanged.

[0047] When in use, an extension joint 102 is provided at the end of the embedded casing body 101 to connect the casing pipe 201, and a limiting groove 202 is provided on the casing pipe 201 to limit the fixing device 203. At the same time, the fixing piece cooperates with the fixing device 203 to fix the position of the embedded casing body 101, so that the embedded casing body 101 will not be displaced due to backfilling, concrete pouring and other operations after being embedded, thereby achieving the effect of improving the installation stability of the embedded casing;

[0048] By arranging the cooperation between the clamp 2031a and the support frame 2032a, the embedded sleeve body 101 can be supported when it is embedded in the ground or embedded close to the ground, thereby ensuring the stability of the embedded sleeve body 101. By arranging the cooperation between the connecting ring 2031b and the oblique support frame 2032b, and fixing the oblique support frame 2032b to the facade, the stability of the embedded sleeve body 101 can be ensured when the embedded sleeve body 101 is installed in the air, thereby achieving adaptability to multiple installation methods.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
