Technical Field
The utility model belongs to the building field, concretely relates to precast concrete component embedded sleeve fixing device.
Background
Compared with a construction mode of in-situ pouring, the prefabricated member has the characteristics of production efficiency, energy conservation, environmental protection and the like which are often mentioned, the member is different from a cast-in-situ part, the difference is the installation of the embedded part, and except that the laminated slab has truss ribs, other prefabricated members need to be provided with the embedded part for demoulding and hoisting during installation. The embedded hanging nail and the embedded sleeve are two main options. The embedded nail that hangs generally has half rubber ball, and the upper end position that can guarantee the embedded nail that hangs is located the prefabricated component upper surface, but complicated demolish technology and great empty breach can influence the quality of component to a certain extent, compare in the embedded nail that hangs, and two above-mentioned problems can effectively be avoided to the embedded sleeve.
Because the structures of the two embedded parts are different, the embedded sleeve does not have hemispherical rubber, so that the stage of dismantling is not needed after the production is finished, and no gap is left on the surface of the component. But pre-embedding the sleeve is not without disadvantages. When the sleeve is embedded in advance, the sleeve is fixed through the corresponding tool piece, but the upper surface of the embedded sleeve cannot be leveled with the upper surface of the prefabricated part due to the material characteristics and production deviation of the tool piece. If pre-buried sleeve is higher than the prefabricated component surface, it is easy relatively to produce the floating face, but later stage installation and filling have trouble and hidden danger, if pre-buried sleeve is less than the prefabricated component panel, the work of wiping face of production process and the form removal after the production is accomplished can be troublesome relatively, if have the clearance between pre-buried sleeve and the frock in addition, it can influence subsequent construction to leak thick liquid.

Detailed Description
In the description of the present invention, it is to be understood that the terms "one end", "the other end", "the outside", "upper", "inside", "horizontal", "coaxial", "central", "end", "length", "outer end", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
The present invention will be further explained with reference to the accompanying drawings.
As shown in the figure, a precast concrete component embedded sleeve fixing device, includes fixing bolt 2, height adjustment pad pipe 4, sleeve frock piece 1 and fixation nut 3, fixing bolt 2 is used for the spiro union to insert and joins in marriage in embedded sleeve 5 upper end, 4 covers of height adjustment pad pipe are joined in marriage on fixing bolt 2, and its lower extreme sets up the frock piece 6 that supports on embedded sleeve 5, frock piece 6 is inverted circular truncated cone structure, 1 one end of sleeve frock piece is used for installing with 7 cooperations of template, and other end cover is joined in marriage on fixing bolt 2 and is supported in 4 tops of height adjustment pad pipe, 3 spiro unions of fixation nut are on fixing bolt 2 and are used for compressing tightly sleeve frock piece 1. Wherein the formwork 7 is a tool for casting the prefabricated part.
In some embodiments, the height adjusting cushion tube 4 is in welded fit with the tooling block 6. In addition, the height adjusting cushion tube 4 and the tooling block 6 are of an integrally formed structure.
In some embodiments, the main body of the sleeve tool 1 is a square steel pipe, and in addition, the main body of the sleeve tool 1 may also be a channel steel or other structures.
Further, an opening for the fixing bolt 2 to pass through is formed in the sleeve tool 1. One end, opposite to the fixing bolt 2, of the sleeve tool assembly 1 is provided with an installation seat 100, and the installation seat 100 is installed in a matched mode with the template 7 through a bolt.
