Abstract
The utility model relates to a kind of nut embedded type curtain wall panel back of the body bolt, which includes nut, expansion sleeve and bolt, which is characterized in that the nut is the flush type nut of tubulose, and one head is equipped with the cone gradually expanded outwardly；Internal screw thread in the flush type nut pore matches with the bolt；The internal diameter of the expansion sleeve and the outer diameter of the flush type nut match, and outer diameter and the basal diameter of one set cone of flush type nut match, and length is suitable with the length of the flush type nut outer peripheral surface rotary generatrix；One of the expansion sleeve is expansion arc, the expansion arc is made of three or more fins for being symmetrical with its axis, the length of each fin is suitable with one, the flush type nut length of cone outer peripheral surface rotary generatrix, and the outer surface of root, which is equipped with, weakens structure.This nut embedded type plate, convenient for the transport after the factorial production, is conducive to the construction efficiency and quality that improve curtain wall with back of the body bolt.
Description
Technical field
The utility model relates to fixed buildings, and in particular to the hiding clamp device of covering or the lining component back side.
Background technique
Curtain wall is the building enclosure of decorative architecture beyond the region of objective existence wall, and the lightweight wall in load-carrying members is hung over as curtain.It is existing
For the hall of heavy construction, also have using the two-sided curtain wall of steel frame construction as partition wall.In order to reduce site operation program, improve
Construction efficiency, curtain wall factory before, operation company can in the building stones plate of curtain wall pre-buried back of the body bolt connector.It is currently used
Back of the body bolt includes conical screw, expansion sleeve and nut, wherein cone, expansion sleeve and screw thread is arranged in the tail end of tapered thread bar
One setting fin (also have and do not set fin) of the cone cooperation of bar tail end.When assembly, by set pipe sleeve one on conical screw
Road is inserted into the connecting hole that bottom set on plate is taper, then be will be pressed into the connecting hole bottom of plate taper, is utilized cone
Expansion sleeve one fin distending is stuck in the connecting hole of plate taper by the cone of shape screw rod tail end.It can be seen that existing
Back of the body bolt building stones plate on necessarily there is one section of screw rod to stretch out, exist if not installing at the construction field (site) and stack that transport is inconvenient to ask
Topic, if installing at the construction field (site) and not only having influenced efficiency because of the limitation such as place, tooling but also influenced installation quality.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of nut embedded type curtain wall panel back of the body bolt, the back of the body bolt
Convenient for the transport after the factorial production.
It is as follows that the utility model solves above-mentioned technical problem scheme:
A kind of nut embedded type curtain wall panel back of the body bolt, the back of the body bolt include nut, expansion sleeve and bolt, and feature exists
In,
The nut is the flush type nut of tubulose, and one head is equipped with the cone gradually expanded outwardly；The embedment
Internal screw thread in formula nut pore matches with the bolt；
The internal diameter of the expansion sleeve and the outer diameter of the flush type nut match, outer diameter and the flush type nut
The basal diameter of one set cone matches, and length is suitable with the length of the flush type nut outer peripheral surface rotary generatrix；Institute
One of the expansion sleeve stated is expansion arc, which is made of three or more fins for being symmetrical with its axis, Mei Geqiao
The length of piece is suitable with one, the flush type nut length of cone outer peripheral surface rotary generatrix, and the outer surface of root, which is equipped with, cuts
Weak structure.
In above scheme, weakening structure set by the fin root, which can be, to be weakened slot or weakens hole, preferably weakening slot.
In order to increase the contact surface between nuts and building stones plate, the reliability of connection, above-mentioned nut embedded type are improved
One improvement project of curtain wall panel back of the body bolt is that the bolt is hexagon flange bolt.
The utility model has following gain effect:
Since nut is designed to the flush type nut of tubulose by the utility model, and it is allowed to and expansion sleeve forms embedment plate
The anchor structure of material, the structure are entirely buried in building stones plate.Since this measure makes the stacking transport for assembling anchor structure plate
It is very convenient, advantageous condition is created for batch production anchoring assembly.Therefore, the utility model can avoid at curtain wall construction scene
Anchoring assembly had both improved construction because narrow field is not available the irregular many deficiencies of tooling, in-site installation personnel's technical ability
Efficiency, and construction quality can be improved.
Detailed description of the invention
Fig. 1 is the structural representation of a specific embodiment of nut embedded type curtain wall panel back of the body bolt described in the utility model
Exploded view, wherein flush type nut and expansion sleeve are half-sectional.
Fig. 2 and Fig. 3 is the structural schematic diagram of expansion sleeve in embodiment illustrated in fig. 1, wherein Fig. 2 is main view, and Fig. 3 is to face upward
View.
Fig. 4 is the usage state diagram of embodiment illustrated in fig. 1.
Specific embodiment
Referring to Fig. 1~3, nut embedded type curtain wall panel back of the body bolt described in this example is by flush type nut 1,2 and of expansion sleeve
Hexagon flange bolt 3 forms.Wherein, one of flush type nut is equipped with the cone 1-1 that gradually expands outwardly, in pore 1-2
Internal screw thread match with the bolt；The internal diameter of expansion sleeve 2 and the outer diameter of flush type nut 1 match, outer diameter and embedment
The basal diameter of 1 one, formula nut set centrum 1-1 matches, the length phase of length and flush type nut circumferential surface rotary generatrix
When；One of expansion sleeve 2 is expansion arc 2-1, and expansion arc 2-1 is made of 4 fin 2-2 for being symmetrical with its axis, each
The length of fin 2-2 is suitable with 1 one, the flush type nut length of cone 1-1 outer peripheral surface rotary generatrix, the outer surface of root
Equipped with weakening slot 2-3.
Referring to fig. 4 and in conjunction with 1~3, the installation method of nut embedded type curtain wall panel back of the body bolt shown in FIG. 1 is as follows:
(1) the counterbore 4-1 to match with 2 outer diameter of expansion sleeve is opened up in plate 4 with drill bit, then selects and is bored with cone 1-1
The downward taper hole 4-2 of horn mouth is formed at the lower part for spending equal tapered wheel grinding counterbore 4-1；
(2) in the counterbore 4-1 for being processed 1 step of flush type nut (1), then expansion sleeve 2 is put on, then using electronic
Tool pushes expansion sleeve 2, will form anchor between the inner wall and cone 1-1 of the fin 2-2 indentation taper hole 4-2 of its expansion arc 2-1
Fixing structure；
(3) pendant 5 is fixed on building stones plate 4 with hexagon flange bolt 3.
