Detailed Description
The utility model aims to overcome prior art's defect, provide a replace the built-in fitting of internal expansion pipe, it is right to combine the embodiment below the utility model discloses do further detailed description.
Example 1
As shown in fig. 1 to 3, an embedded part for replacing an inner expansion pipe comprises a bearing part, a connecting part and a fixing part; the bearing part comprises a mushroom-shaped bearing head 1 and an external thread bolt 2; the mushroom-shaped bearing head 1 is arranged on the top of the outer thread bolt 2. The connecting piece is used for connecting the harness cord suspender, and the fixing piece is used for fixing the position of the embedded part on the concrete template when concrete is poured.
The connecting piece is cylindrical internal thread sleeve 3, and internal thread sleeve 3 passes through threaded connection with outer silk bolt 2. The mounting is fixed plate 4, and the fixed plate 4 centre of a circle department is equipped with concentric mounting hole 6 for cup joint internal thread sleeve 3. Four fixing holes 5 are uniformly arranged on the fixing plate 4 around the circle center.
The external diameter of outer silk bolt 2 matches with the inner tube internal diameter of interior silk sleeve 3, ensures that outer silk bolt 2 can be fixed on interior silk sleeve 3 through the threaded connection mode, and the tight silk seaming of junction of outer silk screw thread and interior silk sleeve 3. The bottom of the internal thread sleeve 3 is inserted into the mounting hole 6 of the fixing plate 4 and connected into a whole in a welding mode.
The inner wire sleeve 3 is flush with the bottom of the fixing plate 4 so that the mixed soil slurry does not penetrate into the inner portion of the inner wire sleeve 3 to cause blockage when the inner wire sleeve is fixed on the formwork.
The use principle of the embodiment is as follows: the embedded part is fixed on the concrete template through the matching of the screw and the fixing hole 5, so that the embedded part is prevented from displacing during pouring; after concrete pouring is finished and concreting is carried out, the template is dismantled, the bottom of the embedded part is exposed in the concrete, and the harness cord suspender can be directly in threaded connection with the inner wire sleeve 3, so that the harness cord suspender is fixed.
In this embodiment, the size of the fixing holes 5 is matched with the size of the common steel nails, the embedded parts are fixed on the concrete template before the structure is poured through the steel nails, the number of the fixing holes 5 is not less than 3, the fixing holes are uniformly distributed, and the concrete template is firmly fixed.
In this embodiment, can carry out the preparation of a plurality of specifications to interior silk sleeve 3 in the built-in fitting for the internal diameter of interior silk sleeve 3 is different, with the harness cord jib of different specifications of matching.
In this embodiment, load-carrying members is mushroom head form and is convenient for mix during earth landing to the space between mushroom head and the fixed plate 4, guarantees that the earth that mixes between load-bearing member and the mounting is closely knit, and it is effective to ensure the later stage bearing.
In this embodiment, the internal thread sleeve 3 may be a variable internal thread sleeve 3, that is, the external diameters of the external thread stud and the harness cord hanger rod do not need to be the same, as long as the internal thread sleeve 3 is respectively matched with the sizes of the two ends connected with the internal thread stud and the harness cord hanger rod.
