Description
Technical field
The utility model belongs to building field, and particularly a kind of Gong later stage finishing that is embedded in the floor lifts ceiling or lifting light fixture and the built-in joint of usefulness such as wood flooring is installed.
Background technology
Usually, people buy new house before moving in, and all will fit up the house.During house decoration, general ceiling and floor two fitting-out works that are absolutely necessary.For ceiling, generally be to adopt the hanging belt method, in the ceiling punching expansion bolt is installed earlier, then decorative panel is hung in the above; And for solid wood class floor, then need keel nails on the cement floor, again with flooring nail at top of keel, this is current at present job practices.But these two kinds of methods all have tangible deficiency, the one, be on the ceiling punching or its difficulty of construction of nailing on the cement floor is all very big, and the intensity of installing also can't guarantee, the 2nd, these two kinds of methods all can be destroyed the concrete structure of building, cause structural strength to descend, influence safety.Especially on the cement floor, nail, be easy to the concrete floor face nailing is worn and cause security incident.The day for announcing is that the notice of authorization CN200971565Y on November 7th, 2007 discloses a kind of ceiling lifting built-in fitting, adopted the main body of column structure to be provided with an eyelet that can supply ceiling to lift towards next end, eyelet is provided with internal thread, the open and flat one-tenth position-arresting disk structure in upper end, the position-arresting disk area offers the form of structure of a hole for nailing at least greater than stylolitic part on the position-arresting disk.But the built-in fitting of this form has only been considered the lifting of ceiling, does not consider the installation on floor, and function ratio is more single, and in fact, the ceiling of resident family lifting downstairs can be used same concrete embedded with the floor installation of resident family upstairs.
The utility model content
The utility model is big for ceiling, the floor finiss difficulty of construction that solves prior art and exist, and installation strength is low, the problem of influence safety and provide construction simple and convenient, intensity height, safe and reliable built-in joint.
Another purpose of the present utility model is can lift ceiling for the problem that solves the function singleness that prior art exists both provides, and the built-in joint of wood flooring can be installed again.
The utility model is to reach the concrete technical scheme that above-mentioned technical purpose adopts to be: built-in joint is by connector and be arranged on link plate on the connector, base is formed, connector is a cylindrical structural, the upper end is the external screw thread post, the lower end is an internal threaded column, be provided with downward extended structure in the middle of the link plate, be provided with and the suitable internal thread of external screw thread post in the extended structure, both sides are provided with fixing hole, the bottom surface of base is a slabbed construction, vertically be provided with the central post of hollow above the slabbed construction, the lower end of connector is fixed in the central post, and the external screw thread post of upper end and the internal thread on the link plate are spirally connected, and the upper end of external screw thread post exceeds link plate.Connector is designed to all attachable up and down structure, the internal threaded column of lower end can be hung ceiling, the external screw thread post of upper end can connect the floor installed part when needed, the problem that interim punching is produced when both having solved finishing, also reached the purpose of dual-use material, simplify the construction formality, saved cost.Link plate is used for fixing connector, and the effect one of base is the position of restriction connector, guarantees the verticality of connector, reaches the purpose of convenient construction, and the 2nd, foreign material such as cement enter internal threaded column, the protection internal thread in the time of also can preventing to construct.The fixing hole of link plate both sides can be fixed on built-in joint on the appropriate location of construction formwork easily.
In the place on needs installation floor, the upper end of external screw thread post connects the floor installed part.Like this, lifting ceiling and twice pre-buried process that the floor is installed, just can be in construction disposable finishing, simplified work progress, saved cost.
As preferably, the bilateral symmetry of central post is provided with the side column of hollow, and the fixing hole of the position of side column and link plate both sides is suitable.The effect of side column is a link plate fixedly the time, provides suitable support to link plate.
As preferably, the plastic construction that base is integrated, the side column on the base is higher than central post.The base of plastic construction is easy to manufacture, and cost is low and can not get rusty in concrete, and the life-span is long.
Built-in joint in use, connector and link plate, base are fixed on the construction formwork by nail, the slabbed construction of base is close to and is connected construction formwork.The effect of nail has two, and the one, during construction built-in joint is fixed on the appropriate location of construction formwork, prevent that built-in joint from moving, the 2nd, when the lifting ceiling, can prevent when screwing in screw that built-in joint from rotating.
The beneficial effects of the utility model are: ceiling, floor construction difficulty that it has solved the prior art existence effectively are big, and installation strength is low, the problem of influence safety.Simultaneously, the utility model both can lift ceiling, again wood flooring can be installed, and one-object-many-purposes and simple in structure is with low cost, is worth of widely use.
