Below in conjunction with accompanying drawing, the invention will be further described:
See Fig. 1 and Fig. 2.
The grout sleeve quick positioner of one embodiment of the invention, comprise screw rod 1, pad 5 and rubber cradle 6, also comprise the eccentric washer 3 of two or more and the push rod 4 corresponding to described eccentric washer 3 quantity, described eccentric washer 3 is enclosed within described screw rod 1, one end of described push rod 4 is fixed on described screw rod 1, described screw rod 1 is provided with limited step 11, when described eccentric washer 3 moves towards the direction of described limited step 11 and stops mobile under the restriction of described limited step 11, described push rod 4 one_to_one corresponding falls in the intermediate throughholes of described eccentric washer 3.
In concrete enforcement, described push rod 4 is perpendicular to described screw rod 1, and the length of described push rod 4 is greater than the radius of the intermediate throughholes of described eccentric washer 3. Can effectively ensure that the motion track of eccentric washer 3 periphery is in change like this.
See Fig. 6, the grout sleeve quick positioner of one embodiment of the invention is in use, first on the operational platform reinforcing bar binding is completed, (template refers to a kind of carrier realizing precast concrete to get out template 8, usually it is welded by steel plate or shaped steel or other materials are made), template 8 has through hole, then the through hole that screw rod 1 passes in template 8 is stretched in grout sleeve 7, and make eccentric washer 3 stretch in grout sleeve 7, limited step 11 is positioned at the lower section of eccentric washer 3, again rubber cradle 6 is enclosed within screw rod 1, its part is made to stretch in grout sleeve 7, another part is positioned at the through hole of mould 8, finally pad 5 is enclosed within screw rod 1, pad 5 is positioned at the top of template 8, after all assembling parts are good, rotary screw 1 (only towards same direction), screw rod 1 drives push rod 3 to rotate then, in the rotation process of push rod 3, the other end of push rod 3 is against the inner peripheral surface of eccentric washer 3, therefore push rod 3 drives eccentric washer 3 to move along the radian track offset, slowly make the excircle of eccentric washer 3 near the inwall of grout sleeve 7, so that eccentric washer 3 have rotated, with maximum radius, the maximum track line that exceedes grout sleeve 7 inner peripheral surface, form the motion track as shown in Fig. 7 a to Fig. 7 c.
If the radius of grout sleeve 7 is r1, the length of push rod 4 is r2, it is r3 with the ring width of the eccentric washer 3 of the other end contact position of push rod 4, can find out, when push rod 3 drives eccentric washer 3 to move, r3 is constantly change, and in the moving process of push rod 4 and eccentric washer 3, always there will be the process that r2+r3 constantly becomes big, in the process, once arrive the stagnation point of r2+r3=r1, (screw rod 1 only turns push rod 4 towards same direction, push rod 4 can not reverse) and eccentric washer 3 cannot move again, mutual even at the cost of one's life with grout sleeve 7, now eccentric washer 3 is to the pressure increase of grout sleeve 7, form swelling state, thus increase mutual frictional force, relative movement cannot be carried out between the two, reach the object of locking grout sleeve 7.
It should be noted that, said process one group of eccentric washer 3 and push rod 4 do not realize, grout sleeve 7 can offset voluntarily laterally at that time, it is thus desirable to eccentric washer 3 more than two and push rod 4, when eccentric washer 3 quantity is two, then angle between two push rods 4 is chosen as 180 degree, like this, two eccentric washer 3 are contrary to the pressure of grout sleeve 7, and grout sleeve 7 cannot offset to any side.
What Fig. 7 a showed is that eccentric washer 3 is at a certain starting position, under push rod 3 drives, position constantly changes, as shown in Figure 7b, until push rod 4 forms swelling state against eccentric washer 3 and grout sleeve 7 inwall, stop rotating, as shown in Figure 7 c, when all eccentric washer 3 all form swelling state with grout sleeve 7 inwall and stop motion, as shown in figure 7d, just can lock grout sleeve 7 to greatest extent, finally with the dead screw rod 1 of nut lock, keep above-mentioned locking state, when rotating nut, eccentric washer 3 moves to template 8 side with grout sleeve 7 entirety, fit with template 8, so just can fix grout sleeve 7, make its accurate positioning, can be carried out next step and concrete build work.

In the present embodiment, see Fig. 4, described eccentric washer 3 is rounded, and its intermediate throughholes is also rounded. The ring width change of this kind of eccentric washer 3 has regularity, and swelling is effective, and certainly, eccentric washer 3 can also be other shape, as long as ring width exists one section of section constantly increased.
Fig. 7 a to Fig. 7 d is explicitly a kind of limiting case that grout sleeve 7 internal diameter is bigger, and contacting with grout sleeve 7 inwall close to ring width maximum of eccentric washer 3 forms swelling state, stops rotating; When the internal diameter of grout sleeve 7 is less, push rod 3 drives the motion of eccentric washer 3 as shown in Fig. 8 a to Fig. 8 c (final state that Fig. 8 c is three eccentric washer 3 is illustrated), the middle scope ring width place of eccentric washer 3 contacts with grout sleeve 7 inwall and forms swelling state, stops rotating. Thus it can be seen that the present invention goes for the grout sleeve 7 of different size, accomplish a kind of multiplex, structural manufacturing process cost. In theory, the inside diameter ranges of the grout sleeve that the present invention can use is at r2+r3MinimumR1 r2+r3Maximum。
In the present embodiment, rubber cradle 6 plays location and the effect of guiding, the present invention is entered in grout sleeve accurately, prevents eccentric washer mechanism body from not entering sleeve completely, and prevent concrete from entering sleeve.
In the present embodiment, as shown in Figure 7a, the contact surface of the other end of described push rod 4 and the inner peripheral surface of described eccentric washer 3 is circular arc face. Circle curved face processing is simple, and during owing to rotating, the length of push rod 4 is constant, and the outer ring rotating eccentric washer 3 during a circle is in the scope of a change, can obtain the numerical value wanted in such scope, and adaptability is good.
In the present embodiment, the inwall of described pad 5 is shaped with internal thread. When eccentric washer 3 forms swelling state with grout sleeve 7, only need to rotate pad 5, eccentric washer 3 just can be made to move to template 8 side with grout sleeve 7 entirety, fit with template 8, thus fix grout sleeve 7, tie down screw 1, such pad 5 is double is used as nut, nut can be saved, enormously simplify structure. When specifically implementing, the periphery of described pad 5 is not rounded periphery, and as shown in Figure 5, pad 5 is designed to hexagon, turns pad 5 to facilitate with spanner, easy to use.
In concrete enforcement, push rod 4 can adopt the mode of welding to be fixed on screw rod 1, and as shown in Figure 3, the spacing between push rod 4 is roughly equal with the thickness of eccentric washer 3, can make in the intermediate throughholes that push rod 4 one_to_one corresponding falls into described eccentric washer 3 like this, ensure fiting effect; Removably connect between described limited step 11 and described screw rod 1, install to facilitate and store, certainly, limited step 11 and screw rod 1 can also be that admittedly connect or integrated, do not affect its using function, still belonging to protection scope of the present invention, limited step 11 is generally located at the end, one end of screw rod 1; In order to facilitate rotary screw 1, the other end at screw rod 1 arranges knob 2, knob 2 is also designed to non-circular structure, preferably it is designed to regular polygon, as directly formed by WELD NUTS, conveniently coordinate with spanner, or directly the other end of screw rod 1 is made positive shape changeable structure, possess above-mentioned functions equally.
