Description

A kind of anchoring piece of slip-off preventing

Technical field

The utility model relates to a kind of anchoring piece, particularly relates to a kind of anchoring piece for building surface, belongs to building installation fitting field.

Background technology

At present, adopt of external thermal insulation system pastes the fixing method of complex heat-preservation nail more.Method is first arranged on warming plate by rubber cement, is then pasted on metope by rubber cement, after bonding adhesive setting and harden, then borehole anchorage, finally criticize and smear plastering mortar and grid cloth.And along with the use of the poor heat insulating material of these surface adhesiveness of phenolic board, XPS plate, very golden plate, cement board, rock cotton board etc., it is more and more frequent that the quality problems that the exterior-wall heat insulation of exterior-wall heat insulation particularly on highrise building comes off occur.How to strengthen the connection of exterior wall heat-preserving system and building masonry wall, the quality problems that minimizing comes off become an important technical problem.Current people usually by increasing adhering heat insulating plate area, set up the methods such as bar for line and bar for line are fixed on outside grid cloth and improve fixing of heat-insulation system and foundation wall.But the effect increasing adhering heat insulating plate area makes limited, and only can improve warming plate and can not ensure that float coat does not come off, so people can by setting up bar for line usually, but along with the increase of bar for line, common bar for line disk has separated float coat and insulation layer, thus add the obscission of heat-insulation system float coat, adopt bar for line to be fixed on outside grid cloth and then can improve difficulty of construction reduction efficiency of construction.

The anchoring piece of existing wall thermal insulating engineering, is made up of plastic expansion sleeve pipe and screw, plays reinforcement effect to the insulation layer in wall thermal insulating, float coat.As shown in Figure 1, cannula center hole is screw hole to the structure of existing plastic expansion sleeve pipe; Sleeve pipe one end is expansion tube 10, and the other end is tail end, and tail end is lamelliform disk 20; The end of screw hole is chamfering 30, in horn-like.This plastic expansion sleeve pipe due to this tail end disk 20 are thin plane structures, plastering mortar adhesion stress during use in it and wall thermal insulating is little, and tensile strength is low; Especially under weather External Force Acting, quality drawbacks such as easily producing the float coat hollowing of wall thermal insulating, ftracture, come off.

Summary of the invention

Applicant have extensively studied the problem of the anchoring ability improving anchoring piece in a large amount of engineering constructions, a kind of structure of creationary invention is simple, the anchoring piece of excellent performance, heat-insulation system firmly can be fixed on skin on the surface by the use of this anchoring piece under the prerequisite not changing traditional construction technique, and do not reduce the bond area of wiping one's face with insulation layer, increase float coat fastness.

Specifically, the utility model is achieved through the following technical solutions:

An anchoring piece for slip-off preventing, comprises expansion sleeve and screw, and expansion sleeve comprises the disk passed for screw of expansion tube for inserting screw and tail end, is wherein provided with at the interface of disk and expansion tube the short holder protruding from disc body surface.

In use, expansion sleeve is inserted in wall body hole, make short holder and insulation layer jam-packed, because short holder protrudes from disc surfaces, space is formed in the middle of insulation layer and disk, finishing mucilage when constructing of wiping one's face is filled completely between short holder and disk, enhances the adhesion stress of wiping one's face with warming plate, reduces the risk come off of wiping one's face.

Wherein, the height of short holder can adjust according to actual needs, and preferably, the height of short holder is 2 ~ 4mm.

Wherein, the shape, size etc. of short holder can adjust as required, and in order to easy to process, be convenient to finishing mucilage simultaneously and fill evenly, described short holder is annular, and be highly 2 ~ 4mm, diameter is 15 ~ 25mm.

In structure of the present utility model, can pour into finishing mucilage in several ways, preferred a kind of structure for be evenly distributed with scallop hole on disk.

When constructing, fill plastering mortar by scallop hole.

Wherein, the radius of scallop hole is 5 ~ 15mm.

In the utility model, the not material of confined expansion sleeve pipe and screw, generally speaking the expansion sleeve of various materials applied of this area and screw are all applicable to the technical solution of the utility model, normally integrated plastic expansion sleeve pipe and metallic screw.

Improved by said structure, the utility model achieves following technological progress:

1) in the insulation construction of building, make insulation layer and exterior wall be connected firmly, float coat and adhering heat insulating plate area increase, and bonding is more firm, is applicable to the connection of various body of wall and heat-insulation system.

2) mounting process is simple, the same with traditional method, easy construction.

Accompanying drawing explanation

Fig. 1 is the structure of traditional anchoring piece;

Fig. 2 is the anchor arrangement of slip-off preventing of the present utility model;

Fig. 3 is the structure of the utility model anchoring piece disk used;

Fig. 4 is the Construction State of anchoring piece of the present utility model in building heat preservation engineering.

Detailed description of the invention

With reference to accompanying drawing 2-4, show a kind of specific implementation of anchoring piece of the present utility model in construction work and application, illustrated application mode is only one of the present utility model, anchoring piece of the present utility model not only for this kind of form of construction work, any traditional anchoring piece can field all can apply anchoring piece of the present utility model.

With reference to figure 2,3, show sectional structure chart and the top view of the anchoring piece of slip-off preventing of the present utility model, the plastic expansion sleeve pipe that disclosed anchoring piece comprises metallic screw 1, is made up of the disk 3 of expansion tube 2 and its tail end, there is short holder 4 at plastic disc and expansion tube interface position, and plastic disc is evenly distributed with scallop hole 5.

Wherein, expansion tube 2 is expansion area of the band dentation of length about 30 ~ 45mm, metallic screw one end band metal cap head, another end band is screw thread, diameter is consistent with inside expansion sleeve expansion area, and bar for line is knocked in by metallic screw and made expansion sleeve bottom expansion, thus reaches anchorage effect.

With reference to accompanying drawing 3, 4, show the using state of anchoring piece of the present utility model, concrete form of construction work is first adopt Churn drill to hole in building basic unit 6, then by expansion sleeve load hole, short holder is made to press insulation layer 7, finally metallic screw knocked in or be screwed in expansion sleeve 2, expansion sleeve afterbody expansion area distending is engaged with base course wall, thus reach the object be fixed on by warming plate on body of wall, when proceeding to float coat 8 and constructing, plastering mortar is filled in the gap of plastic disc 3 and insulation layer 7 through scallop hole 5, thus increase the bond area of float coat 8 and insulation layer 7, after plastering mortar is solid, imbed middle bar for line of wiping one's face and drawknot is formed to float coat, it is firmly fixed on construction wall.
