Specific implementation mode
Illustrate the specific implementation mode of the present invention with reference to the accompanying drawings and examples, but following embodiment is used only in detail
It describes the bright present invention in detail, does not limit the scope of the invention in any way.
Involved building structure is unless otherwise instructed conventional structure in the examples below；Involved construction is former
Material is unless otherwise instructed widely used conventional raw materials in engineering；Involved construction technology, such as nothing are especially said
It is bright, it is common process.
Embodiment 1：It is prefabricated component as shown in Figure 1 and Figure 2, length 1000mm, width and height to need prefabricated PC components 1
Degree is 200mm.
The groove forming method of PC components 1, comprises the steps of：
1）PC member recess designs.
Referring to Fig. 1, Fig. 2, in the present embodiment, the bottom settings of PC components 1 there are three the identical square indentations 2 of shape,
The length of side of groove 2 is 60mm, deep 20mm.Intermediate groove 2 occupy the center of bottom surface, and the groove 2 at both ends is distributed along longitudinal direction, adjacent
The spacing of groove 2 is 230mm.For ease of the demoulding after prefabricated, the side of groove should have certain draft angle, can be according to recessed
The combined factors such as size, shape, the depth of slot consider to determine, usually 10 °~20 °.In the present embodiment, the side of groove 2
Draft angle is 15 °.
The roughness in face where groove 2 can increase is convenient for the combination of cast-in-place concrete and prefabricated PC components 1, enhancing hard
Solidity.
2）Steel bump design makes.
It is designed according to the groove on 1 surface of PC components, designs corresponding steel convex block 3.
Referring to Fig. 3, the shape of steel convex block 3, size and groove 2 are consistent, and bottom surface and top surface are square, four sides
The 15 ° of inclinations in face and vertical direction, it is consistent with the draft angle of groove 2.
The height of steel convex block 3 is 20mm, consistent with the depth of groove 2.Steel convex block using 20mm common carbon structural steels or
Low-alloy structural steel is made, and is made after cutting at processing four inclined sides by milling machine again after square.
3）Die surface is cleared up.
Mold uses steel mold, is composed of polylith steel form, is made of 10mm steel plates, size and PC components 1
Respective surfaces size be consistent.The upper surface of steel form corresponding with the bottom surface of PC components 14, in particular for pasting, steel is convex
The corresponding position surface of block 3, should derust, clear up, and greasy dirt dust and dirt etc. be cleaned out, and keep drying.Similarly, steel convex block 3
Bottom surface will also be derusted, be cleared up.
4）Steel convex block is bonded.
A. steel form 4 and steel convex block 3 are kept flat on smooth terrace or workbench, with horizon rule inspection and leveling, are prevented
Only glue trickles to side when smearing structure glue.
B. according to 1 groove design position of PC components, on steel form 4, on the basis of central cross line, in die surface
The side, angle control point and positioning contour line of corresponding steel convex block are drawn with slate pencil.
C. in the correspondence surface that the needs of steel convex block 3 and steel form 4 are bonded, difference smearing structure glue.It is too thin or too thick
All it is unfavorable for strong bond, experimental researches prove that, adhesive effect is preferred when smearing thickness about 1mm.Then according on steel form 4
Convex block outline line, bond and adjust position, press with finger about 5 minutes positioning adhesives.Modified propylene is used in the present embodiment
Acid esters adhesive, with applying film mixing, under room temperature environment, 3min gluings are bonded under finger pressure, and 5~10min positioning, 30min reaches
The 50% of maximum intensity fully can reach maximum intensity for 24 hours after solidification, and use environment is at -60 DEG C -100 DEG C.
D. after 3 positioning bonding of steel convex block, in 5min, the structure glue that will be overflowed from 3 bottom periphery of steel convex block when bonding,
It is cleaned out with scraper.
E. after steel convex block 3 is bonded with steel form 4, at room temperature, 30min is stood.Paying attention at this time should not be convex to template and steel
Block 3 is disturbed, and ensures structure adhesive curing, 3 accurate positioning of steel convex block.
5）Mold assembles.
After structure gluing knot 30min, you can according to the production requirement of PC components 1, carry out the assembling of mold.
6）Component produces.
Post-modification acrylate adhesive reaches maximum intensity within 24 hours, and steel convex block 3 is firmly bonded with steel form 4 at this time,
Reinforcing bar is installed, casting concrete carries out component production in mold.
7）Component demoulds.
After the completion of PC components 1 produce, in the case where ensureing component not arrisdefect truncation, demoulded.When demoulding, first unclamp
Connection bolt between mold and fixture gently tap steel mold edge and start after concrete surface and steel mold surface loosen
Take out mold.4 stripping direction of steel form and 1 plane perpendicular of PC components ensure smoothly to disengage between steel convex block 3 and groove 2, prevent
Destroy 2 oral area concrete of groove.
After demoulding, on the PC components 1 of 3 corresponding position of steel convex block, forms groove 2 and pay attention to groove during component conservation
2 finished product protection.
8）Steel convex block detaches.
Clear up the concrete laitance on steel mold surface.To identical PC components, 3 position of steel convex block is constant, and convex block shape is not
Become, mold and convex block recycle.To change the location and shape of steel convex block 3, by 3 position of steel convex block of steel form 4, electricity consumption
Stove carries out local heating.A kind of easy mode of heating is erected 4 level of steel form, electric furnace（Electric furnace heating wire）It is placed on punching block
Under plate 4, the position to being just bonded steel convex block 3 is heated.It can certainly be heated using infrared panel according to actual conditions, be infrared
The mode of heatings such as pipe heating, infrared stove heat and inductive heating.Common modified acrylic ester adhesion agent, it is Celsius to be heated to 120
Degree, you can soften, start to melt.Melt to structure glue, takes around 3min.In glue melting process, cutter auxiliary can be used
Steel convex block 3 is removed, then the glue on 4 surface of steel convex block 3 and steel form is cleaned out with scraper, rag is used in combination to wipe
Only.The steel convex block 3 and steel form 4 cleaned out can recycle.
The flow of PC member forming process with groove of the present invention is referring to Fig. 5.
Using gluing hot melting process, the work in steel mold surface soldered, cutting can be saved, it will not be on steel mold surface
There is welding slag, reduces the breakage rate of steel mold.
Operating process is simple, environmental protection, at low cost, saves profession electric welding, the work of cutting worker, common laborer can be complete
At.
The present invention is described in detail above in conjunction with drawings and examples, still, those of skill in the art
Member, can also be to each specific steps, the parameter in above-described embodiment it is understood that without departing from the purpose of the present invention
It changes, forms multiple specific embodiments, be the common variation range of the present invention, be no longer described in detail one by one herein.
