The specific embodiment
Elevator shaft mould described in the utility model is referring to shown in Fig. 1～13, four jiaos respectively by rigid angle mold 1 and two stereotype plates 2 by bobbin hold 3 and bobbin hold coupling beam 4 and form four typing assemblys, form the outline of tube mould, by the engineering section four block filling plates 7 need be set between four typing assemblys, form the tube mould plane of requirement of engineering by back cord 8, there is retractable frame 5 at tube mould center, is connected with tube mould abutment wall by force transmission rack 6, and the bottom of each stereotype plate is connected with a fixedly return pulley 9.
Be fixed with the connector 6.1 of built-in pin-and-hole on the rib of the limit of stereotype plate 2, force transmission rack 6 two ends are connected with stereotype plate 2 with taper 6.2 by connector 6.1.
Corresponding tailgate platform supporting leg position, described tube mould both sides is respectively equipped with two supporting leg preformed hole diaphragm capsules.Supporting leg preformed hole injection moulding diaphragm capsule is made up of with injection mould box base 10.1 the injection moulding diaphragm capsule 10 of band edge rib, and the injection mould box base is connected with the tube mould by screw, and the injection moulding diaphragm capsule is that plug-in card is connected with the injection mould box base.The injection moulding diaphragm capsule adopts the grafting principle of plastic bottle closure to be connected with base.Injection mould box base height is determined according to the construction floor height.After concrete setting, the injection moulding diaphragm capsule of band edge rib promptly is mounted in the concrete wall, and in the time receiving in the tube mould, base goes out with the tube die drawing.Because of injection moulding diaphragm capsule length and body of wall with wide, so the supporting leg preformed hole is penetrating.Because of there not being the preformed hole release problems, in the general hole the concrete residue can not appear, even if residue occurs, penetrating preformed hole also is convenient to remove.
The folding and unfolding relation of tube mould and utilization are referring to Fig. 3: the interior receipts state of tube mould when tube mould extratensive type attitude and form removal when comprising formwork among Fig. 3.When receive in the retractable frame a apart from the time, the four sides abutment wall of tube mould with within receive a distance, receive 0.5a under the drive of the online bearing of rigid angle mold, receipts 0.707a in the drift angle the both sides in.This moment, whole tube mould promptly left concrete wall, and the injection moulding diaphragm capsule is because concrete bonding is embedded in the concrete wall, and the diaphragm capsule base is extracted with cylindrical shell, and the tube mould can hang out.
Referring to Fig. 6,7,8,9, be injection moulding diaphragm capsule structure and the signal of insertion relation, injection moulding diaphragm capsule length and body of wall are with wide, and two ends are clamped by template, under the concrete buoyancy, mainly consider shearing resistance, are can meet the demands fully for the injection moulding diaphragm capsule.
Referring to Figure 10,11, when retractable frame rotated, threaded cross foundry goods will move up and down the b distance along screw rod, no screw thread cross foundry goods is because the effect of baffle ring, and can only rotate can not axially-movable, like this, under the effect of connecting rod, girt will the interior d of receipts length be or open to be c length outward.Make whole tube mould realize actuating by force transmission rack.
The floor height conversion is referring to Figure 12, and tube mould height is determined by maximum standard floor height.H is the pouring floor height.H is that the tailgate platform supporting leg is to the flat upper surface height.E is return pulley+tube mould and lower-layer concrete overlap height.When floor height changes, retighten the diaphragm capsule base by the requirement of new pouring floor height and get final product.Transfer pair the utility model of we can say floor height is a lead-pipe cinch.But for storehouse, ground, common layer, generally highly all between 4.8 to 5.4m, change, this moment, available tube mould stack construction realized (seeing Figure 13), promptly on standard knot of the present utility model, add a standby joint, standby joint links together by shaped steel and bolt and standard knot, makes the height of a mould reach 4.8 to 5.4m.
Referring to Figure 12, Figure 14～20, the supporting tailgate platform of this and described elevator shaft mould, comprise tailgate platform structural skeleton g1.0, tailgate platform leveling lever supporting leg assembly g2.0 and elastic guide wheel apparatus assembly g3.0, tailgate platform structural skeleton g1.0 is made up of tailgate platform structural skeleton girder g1.1 and tailgate platform structural skeleton side bar g1.2, tailgate platform leveling lever supporting leg assembly and elastic guide wheel apparatus assembly are fashion-part, and fashion-part links to each other with the tailgate platform structural skeleton by bolt.
Supporting leg crossbeam g2.1 and the supporting leg column g2.2 of tailgate platform leveling lever supporting leg assembly g2.0 are rigidly connected, be hinged with supporting leg lever g2.3 with the supporting leg column, the wall end of going into of supporting leg lever is provided with the backing plate g2.8 that the supporting leg lever can littlely revolve, the other end is connected by bearing pin g2.9 with supporting leg U type connecting rod g2.4, whole supporting leg is connected with the tailgate platform structural skeleton with tailgate platform structural skeleton connecting bolt g2.6 by supporting leg, supporting leg U type small end be provided with supporting leg leveling bolt g2.5 and on carry hole g2.7.Supporting leg U type connecting rod rides on the tailgate platform structural skeleton girder bar g1.1 by supporting leg leveling bolt, so the bearing pin that supporting leg U type connecting rod is connected with the supporting leg lever needs in supporting leg crossbeam g2.1 and installation again after the tailgate platform structural skeleton is connected.
The elastic guide wheel support of elastic guide wheel apparatus assembly g3.0 is 45 ° and is installed in tailgate platform structural skeleton inboard, be connected and fixed by elastic guide wheel support and tailgate platform structural skeleton connecting bolt g3.6, rack beam g3.2 and bracket upright post g3.1 are hinged, the rack beam outside is provided with directive wheel g3.3, the inboard is provided with extension spring g3.5, the extension spring upper end is connected with the tailgate platform structural skeleton, the bracket upright post outside is provided with backstop g3.4, rack beam is an angle with horizon all the time under the extension spring effect.When tailgate platform is hung in the hoistway, 4 directive wheels that are distributed in the tailgate platform corner angle and exceed the hoistway edge will be squeezed, and make tailgate platform remain center condition.
The embodiment of tailgate platform combined unit illustrates referring to Figure 21～23:
Referring to Figure 22, when needs tailgate platform combined unit rose, the supporting leg lever was subjected to the interior automatically receipts of the extruding of concrete wall.When platform rose to last layer supporting leg preformed hole, the supporting leg lever stretched out under action of gravity automatically, this moment four leveling bolts all fall back on the flat upper surface, and with flat upper surface in vertical state.Illustrate that four supporting legs all go into groove (seeing Figure 21).If the supporting leg groove that submerges is arranged, its corresponding leveling bolt will inevitably stretch out flat upper surface, illustrates that the tailgate platform combined unit carries on also will continuing, till this leveling bolt falls back to flat upper surface.Degree of safety is directly perceived thus.
Referring to Figure 23, when needs tailgate platform combined unit descended, last promoting or transferring levelling peg was carried hole g2.7 and is exposed table top on U type connecting rod, after penetrating reinforcing bar, supporting leg promptly is positioned, and the supporting leg lever is taken in the tailgate platform combined unit, and this moment, the tailgate platform combined unit can freely descend.
