Abstract
The present invention discloses a concrete partition wallboard. The edge density of the light wallboard substantially coincides with the core density, and the density range is from 1.25 g/cm#+[3] to 1.35 g/cm#+[3]. The present invention has excellent mechanical properties of the wallboard and good use effect.
Description
Technical field
The present invention relates to a kind of concrete partition.
Background technology
At present about state's inner wall panel ubiquity, up and down the density unevenness weighing apparatus, limit pine and phenomenon such as easy to crack appear.This has just influenced as new wall material and has replaced the clay solid brick effect of ruining ground, power consumption, contaminated environment, has had a strong impact on applying of novel machine-processed Light trabs especially.
The output gear shaft of present domestic forming machine transmission case mostly is a kind of form, and promptly every output shaft rotating speed is identical, and every rotation direction (left-handed or dextrorotation) is fixing.
The Light trabs that the forming machine of this kind transmission case form is produced, spiral reamer feeding amount in both sides causes wallboard both sides solidity ratio middle little inadequately, continuous microscopic checks usually appears in extrusion jolt moulded process and corner angle uneven, place, slab crack, slight stressed back comes off at once, and the subject matter of exposure has:
(1) quality of machine-processed Light trabs, much bigger compared with the advantage of other novel wall materials, various physical and mechanical property indexs can reach the requirement of the JG3063-1999 of Ministry of Construction newest standards.But, about the quality ubiquity wallboard of wallboard, density unevenness weighing apparatus up and down, in the application through the test of daring not accept.
(2) be example with master ga(u)ge lattice 90 plates: there is subject matter in the 1# reamer, the 2#-6# reamer screw rod internal diameter consistent with rotating speed, rotation direction are arranged in pairs or groups unreasonable, it is also even inadequately to cause the wallboard area to account for the density of 70% middle part again, and the slab of indivedual reamers top is because the different loose and pitted skin phenomenon of degree appears in meeting under feeding.
Summary of the invention
The objective of the invention is to develop the Light trabs of a kind of limit density and core consistent in density, forming machine by reamer speed change and reducing, increased the feeding amount of forming machine both sides spiral reamers, whole spiral reamers are moved under the feed that compares uniformity, material extrusion state, make the Light trabs of limit density and core consistent in density.
As shown in Figure 1, Light trabs of the present invention has concave-convex connection structure for two ends, the left and right sides, the flat batten of seven through holes that laterally evenly are intervally arranged in the plate.
Realize that the present invention has done following test:
A group: 7 reamers of forming machine, blade external diameter Φ 78mm, screw rod internal diameter are the Φ 52mm drawing wallboard that feeds intake.The result: fin one side, promptly no matter 1# reamer position adopts any light aggregate concrete match ratio, because under feeding, is the particle state, without exception can not moulding; Fin one side, i.e. 7# reamer position, though moulding reluctantly is serious rarefaction, density, intensity are very low.
B group: 1#, when 7# reamer internal diameter contracts to Φ 42mm by Φ 52mm, the equal moulding in wallboard both sides resembles an available wallboard, but that both sides also show is loose, 1# reamer position is that fin one side is more loose than opposite side.
C group: when fin one side, i.e. the wallboard (the 7# reamer does not raise speed) that 1# reamer speed-raising back draws, this side density obviously improves: go up, the side two sides is smooth, smooth, fine and close, outward appearance is excellent, density, excellent strength.
Three groups of test result analysis
The wallboard both sides are loose, illustrate under feeding.And the test of A group, 1#-7# reamer pusher amount should be basic equating in theory.Why the slab at 1# reamer position at all can not moulding in the arm-tie practice, though 7# reamer position can moulding special again loose except that two limit moulds of forming machine frictional resistance is arranged and influence 1#, 7# reamer feeding amount has the deficiency slightly, more will analyze the difference that the feeding amount is born in every reamer feeding of this reamer feeding and middle 2#-6#.Theoretical calculate and production practices prove, the main cause of wallboard both sides " limit pine ", be the feeding amount born of 1#, 7# reamer greatly and can not send the q.s material and cause.
The speed-raising ideal scheme:
When 2#-6# reamer rotating speed equates, adjust the screw rod internal diameter, the different rotation directions of adjacent reamer, as shown in Figure 3 reasonably combined.
Each position density fluctuates after testing at 1.259g-1.377g/cm
3Between.Density is even substantially, and is more satisfactory.
Loose, the too small way of density in solution panel edges position
The internal diameter of former 1#-7# reamer is 52mm, now dwindle 1#, 7# reamer internal diameter occurrence, making 1# reamer internal diameter is 44mm, 7# reamer internal diameter is 47mm, by enlarging the appearance material space between screw rod blade and the helical pitch cavity, improve the mass transport amount in the unit interval, detect the test specimen volume with cutting 2 * 2 * 2cm standard small specimen or with Archimedes's method.As calculated, panel edges density is from＜1.000g/cm
3Bring up to 1.266g/cm
3Than the balanced density 1.309g/cm in middle part
3Still little 0.046g/cm
3, promptly edges of boards are under feeding, still lack 3.510%.The way that solves is: when 1#, 7# reamer dwindle internal diameter, improve rotating speed.
Under the certain prerequisite of helical pitch, screw rod internal diameter, major diameter of thread, the speed-raising of dumpling cutter is limited, promptly progressively raises speed from lower rotating speed, and the pusher amount progressively increases.After rotating speed increases to certain value, along with the raising of rotating speed, the pusher amount will begin to descend.Do experiment with variable speed electric motors, particularly, rotating speed is found that to general light concrete material, 190-200 rev/min proper when 150 rev/mins are progressively brought up to 250 rev/mins of searching optimum speeds.So, determine that in design rotating box output shaft rotating speed is 196 rev/mins.In order to improve the feed amount of limit cutter, we suitably improve 1# reamer rotating speed, and the wallboard that draws is detected.1.250g/cm before panel edges density never raises speed
3Bring up to 1.350g/cm
3,, just as " object fringing ", the globality of wallboard is made moderate progress, thereby has reached the improved experiment purpose of forming machine technical performance with wallboard middle part density basically identical and slightly higher.
The ratio of each reamer feeding amount of forming machine.With 90 type wallboards is example:
| The reamer sequence number | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| The ratio of the corresponding wallboard sectional area of reamer | 1.402 | 1 | 1 | 1 | 1 | 1 | 1.243 |
(the wide 595MM of plate, thick 90MM, aperture 59MM)
Guarantee that each position of walling (especially both sides groove location) uniformity, density that forming machine makes are the same, must the core component reamer of forming machine carefully be designed.Make it can guarantee the material supply unanimity at each position in the wallboard forming process.Make No. 1 No. 7 reamer undergauges, speed-raising, the reasonable rotation direction of collocation, adopt technologies such as double thread.After the walling forming machine uses this kind of reamer, the light-weight wall material of making, through check, the density at its each position all guarantees in walling national standard scope, has realized each position density uniformity of wallboard, the mechanical property excellence of wallboard, result of use is good.
Following table is the major parameter of the used reamer of walling forming machine of the present invention:
| The reamer sequence number | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| Reamer feeding screw external diameter (mm) | 75 | 75 | 75 | 75 | 75 | 75 | 75 |
| Footpath (mm) at the bottom of the reamer feeding screw | 45 | 52 | 52 | 52 | 52 | 52 | 50 |
