Stainless steel adapting piece 4 shown in Fig. 2 includes barred body 41, and nominal diameter is between 3.0mm-20.0mm, according to tool
Body construction requirement is processed.Barred body 41 is made of smooth surface section 411, the first thread segment 412 and the second thread segment 413.Smooth surface section
411 general sides are machined with the position of rule of " ▽ ".The both ends of barred body 41 are located at internal lobe wallboard 1 and siphonal lobe wallboard 2 respectively, respectively
For inner face 414 and outer end face 415, wherein the first thread segment 412 is between the outer end face and the smooth surface section 411,
Two thread segments 413 are between the inner face and the smooth surface section 411.As shown in Figure 3-4, outer anchoring piece 42 and interior anchoring piece
43 shapes are identical, meet the requirement of simplified technique；Outer anchoring piece 42 is connected through connection screw thread 4211 and in hole 421
One thread segment 412 is connected, and similarly, interior anchoring piece 43 is connected through 4311 and second thread segment of connection screw thread in hole 431
413 are connected.Barred body 41 is connected with the mode that anchoring piece 42,43 is connected through a screw thread so that its stable connection is reliable, enhances
The anti-pull-out property of connector.The both ends of the surface of outer anchoring piece 42 are respectively first end face 422 and second end face 423, wherein first
End face 422 is compared with second end face 423 closer to insulating layer 2, while the cross-sectional area of first end face 422 is more than second end face
423 cross-sectional area, and the cross-sectional area of first end face 422 is not less than the cross-sectional area of the anchoring piece rest part, it is described
The cross-sectional area of second end face 423 is not more than the cross-sectional area of the anchoring piece rest part, and connecting hole 421 is from first end face
422 open up toward the direction of second end face 423.Barred body 41, anchoring piece 42,43 processing dimension parameter according to Specific construction requirement and
It is fixed, it is however generally that following table should be met：
Table 2：The requirement of stainless steel adapting piece processing dimension
| Barred body diameter d | Anchoring piece outer diameter | Anchoring piece length | Screw thread specification M | Reach |
| 3.0-20.0mm | 2.5d-5d | 1.25d-5d | M(d+0.5)*0.35-2.5 | 1.25d-5d |
The shape of anchoring piece needs to process according to Specific construction, generally the group of terrace with edge, round platform, terrace with edge and prism or cylinder
Any one in fit, round platform and the assembly of prism or cylinder, in the present embodiment the shape of anchoring piece 42,43 for round platform with
The assembly of hexagonal prisms.In actual installation process, using the anti-method for playing cast.It first places and uses on horizontal plane (such as ground)
It in pouring the mold of siphonal lobe wallboard 3, then pours into concrete and forms siphonal lobe wallboard 3, siphonal lobe wallboard 3 is horizontal at this time.Outside
Hardening process needs the long period before 3 hardened forming of leaf wallboard, and insulating layer 2 is laid on siphonal lobe wallboard 3, and insulating layer 2 can be by
Thermal insulation material forms, such as polyurethane foam, polystyrene, phenol formaldehyde foam etc., and having been accomplished fluently in advance on insulating layer needs to install
The hole of connector position is passed down through insulating layer 2 after the completion of the laying of insulating layer 2, then by connector from the upside of insulating layer 2,
Due to the shape of the round platform and hexagonal prisms assembly of outer anchoring piece 42, it is similar to a kind of effect of drill bit, even if being opened on insulating layer 2
Hole is smaller, and outer anchoring piece 42 can also pass through, and opens too much so as to avoid the hole of insulating layer in work progress, influences wallboard
Heat-insulating property, meanwhile, the austenitic stainless steel that thermal conductivity factor is relatively low in stainless steel can be selected, further to optimize connector
Heat-insulating property；In addition, the hole for being used to pass through connector 4 on insulating layer 2 is smaller, the effect for being in clamping connection part 4 is also played.It wears
It crosses after insulating layer 2, outer anchoring piece 42 is inserted into also unhardened siphonal lobe wallboard 3, and the depth of insertion is to be no more than connector stick
Subject to " ▽ " scale on body, since the length of connector barred body 41 is more than the thickness of insulating layer 2, anchoring piece 42 is inserted into beyond institute
Inside siphonal lobe wallboard 3.The width of insulating layer is generally 40mm, according to the difference of internal lobe wallboard 1, siphonal lobe wallboard 3 in practice of construction
Thickness, the length of connector 4 is between 100mm-420mm.Previous experiments show that the arrangement spacing of connector is 400mm-
600mm is preferred, and concrete numerical value is determined according to construction requirement.After the completion of the inserting step of connector, then in the upside of insulating layer 2
Carry out the concrete cast of internal lobe wallboard 1 so that interior anchoring piece 42 is wrapped in be formed in the concrete of internal lobe wallboard 1, treats outer
Leaf wallboard 3 is molded with the concrete hardening that internal lobe wallboard 1 is poured into a mould, that is, completes the making of precast concrete sandwich heat preservation wallboard.
Embodiment 2
Connector 4 is first put down the bar-mat reinforcement of outer anchoring piece 42 and siphonal lobe wallboard 3 using iron wire or steel wire in installation process
The position in face is relatively fixed, and the concrete cast of siphonal lobe wallboard 3 is carried out again afterwards, due to the first end face 422 of outer anchoring piece 42
Diameter be 2.5-5 times of 41 diameter of barred body, provide enough banding fixed spaces for iron wire or steel wire, it is therefore prevented that poured into a mould
The displacement of connector 4 in journey after siphonal lobe wallboard 3 have passed through one of hardening process time, is laid with heat preservation on siphonal lobe wallboard 3
Layer 2, has accomplished fluently the hole for needing installation connecting element position in advance on insulating layer, during insulating layer 2 is laid with, due to interior anchor
The shape of firmware 43 is similar to a kind of effect of drill bit so that it can pass through smaller hole on insulating layer, avoid construction
The hole of insulating layer is opened too much in the process, influences the heat-insulating property of wallboard, after the completion of the laying step of insulating layer 2, then is being kept the temperature
The upside of layer 2 carries out the concrete cast of internal lobe wallboard 1 so that interior anchoring piece 43 is wrapped in the coagulation to form internal lobe wallboard 1
In soil, treat that siphonal lobe wallboard 3 is molded with the concrete hardening that internal lobe wallboard 1 is poured into a mould, that is, complete precast concrete sandwich heat preservation wallboard
Making.
To sum up, the utility model for stainless steel adapting piece processing technology in the prior art is complicated or thermal and insulating performance not
The shortcomings that good, it is proposed that a kind of new precast concrete sandwich heat preservation wallboard stainless steel adapting piece, barred body are equal with anchoring piece
Simple shape can be completed by simple processing technology, and the two is attached by simple and reliable screw thread, also, be anchored
The shape design of part, makes connector also have many advantages, such as that heat-insulating property, anti-pull-out property are good, great engineering application value.Meanwhile
Using the precast concrete sandwich heat preservation wallboard of the stainless steel adapting piece, also possesses the advantages of durable stable, good heat insulating.
Although the utility model is disclosed as above with preferred embodiment, its be not for limiting the utility model, it is any
Those skilled in the art without departing from the spirit and scope of the utility model, can make possible variation and modification, all
It is the content without departing from technical solutions of the utility model, appoints according to the technical essence of the utility model to what above example was made
What modification, equivalent variations and modification, each falls within the protection domain that the utility model claims are defined.
