Изобретение относитс к строительству и предназначено преимущественно дл применени его на монтаже сборных железобетонных плит шахт лифтов в каркасных здани х с применение.м конструкций серии ИИ-04.The invention relates to construction and is intended primarily for use in the installation of precast concrete slabs of elevator shafts in frame buildings with the use of structures of the II-04 series.

Известен кондуктор дл монтажа элементов каркаса здани , включающий составной корпус, рабочие площадки, фиксаторы колонн , вертикальные опоры, причем корпус выполнен из телескопических частей, внешн из которых имеет объединенные между собой навесные рабочие площадки, расположенные в разных уровн х и соединенные с вертикальными опорами, а внутренн часть щарнирно соединена с нижней рабочей площадкой подкосом 1.A jig is known for mounting building frame elements comprising a composite body, working platforms, column holders, vertical supports, the body being made of telescopic parts, outwardly of which are mounted interlocking working platforms located at different levels and connected to vertical supports, and the inner part is hingedly connected to the lower working platform by the strut 1.

К недостатку известного кондуктора следует отнести наличие открепл емой и переносимой отдельно верхней секции, что требует дополнительных трудозатрат при его перестановке.The disadvantage of the known conductor should be attributed to the presence of the detachable and separately portable top section, which requires additional labor costs during its transfer.

Известен и другой кондуктор, предназначенный преимущественно дл монтажа футеровочных панелей или колец стволов дымовых труб, включающий смонтированные на основании стойки каркаса распорки. КОНСТРУКЦИЙAnother conductor is also known, which is primarily intended for mounting lining panels or rings of chimney stems, including spacers mounted on the base of the frame stand. CONSTRUCTIONS

наклонные радиальные направл ющие, на которые установлены подвижные подущки, св занные между собой трособлочной уравновещивающей системой из неподвижных и подвижных блоков, огибаемых канатом 2.inclined radial guides, on which movable pads are mounted, interconnected by a cable-block balancing system of fixed and movable blocks, skirted by a rope 2.

К недостатку этого кондуктора следует отнести наличие основани , расположенного за внещним контуром горизонтального сечени ствола бащенной конструкции, а также смонтированных на основании стоек каркаса , распорок и наклонных радиальных направл ющих .The disadvantage of this conductor should be the presence of a base located behind the external contour of the horizontal section of the barrel of the sheathed structure, as well as mounted on the base of the frame posts, struts and inclined radial guides.

Наличие перечисленных признаков заттрудн ет использование кондуктора непосредственно на монтажном горизонте, причем дл обеспечени возможности перестановки такого кондуктора по высоте требу15 ютс существенные его конструктивные изменени .The presence of the listed signs makes it difficult to use the conductor directly on the mounting horizon, and significant changes in its design are required to ensure that the conductor can be rearranged in height.

Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс кондуктор дл монтажа строительных конструкций, преимущественно сбор20 ных плит щахт лифтов, включающий каркасную раму с фиксирующими атементами 3.The closest to the invention to the technical essence and the achieved result is a jig for mounting building structures, mainly assembling 20 elevator plates, including a frame frame with fixing elements 3.

Поименение этого кондуктора позвол ет Значительно повысить эффективность монтажа не только самих шахт, но и лифтового оборудовани за счет исключени выверочных операций на монтаже блоков шахты , а также направл ющих кабины и противовеса лифта.The name of this conductor allows a significant increase in the efficiency of the installation not only of the mines themselves, but also of the lift equipment by eliminating alignment operations on the installation of the shaft units, as well as the cab guides and the counterweight of the elevator.

Однако блочный (тюбинговый) монтаж шахт лифтов возможен при наличии на монтажной площадке крана соответствующей грузоподъемности, а при поэлементном монтаже шахт лифтов упом нутый кондуктор очень трудно переставить на новый монтажный горизонт.However, a block (tubing) installation of elevator shafts is possible if the crane has an appropriate lifting capacity on the assembly site, and in case of step-by-step installation of elevator shafts the said jig is very difficult to rearrange to a new assembly horizon.

Цель изобретени - снижение трудоемкости перестановки кондуктора на новый монтажный горизонт и повышение точности монтажа.The purpose of the invention is to reduce the labor intensity of relocation of the conductor to the new mounting horizon and increase the accuracy of installation.

Эта цель достигаетс тем, что в кондукторе дл монтажа строительных конструкций , преимущественно сборных плит шахт лифтов, включающем каркасную раму с фиксирующими элементами, каркасна рама в поперечном сечении выполнена крестообразной , имеет на выступах шарнирно закрепленные одним концом и вертикально ориентированные рамки, на которых смонтированы фиксирующие элементы, и снабжена опорными пластинами с приводом их выдвижени в горизонтальной плоскости. Кроме того, рамки на уровне выдвижени опорных пластин снабжены перемычками, в каждой из которых выполнено отверстие дл пропуска пластин, привод выдвижени которых выполнен в виде шарнирно соединенных с ними парных т г, свободные концы которых соединены винтовым механизмом, имеющим штурвал.This goal is achieved by the fact that in a conductor for mounting building structures, mainly precast slabs of elevator shafts, including a frame frame with locking elements, the frame frame in cross-section is made cross-shaped, has hingedly fixed ends and vertically oriented frames on which are fixed elements, and provided with support plates with a drive of their extension in the horizontal plane. In addition, the frames at the level of extension of the support plates are provided with jumpers, in each of which there is an opening for the passage of the plates, the extension drive of which is made in the form of paired rods hinged to them, the free ends of which are connected by a screw mechanism having a steering wheel.

На фиг. 1 представлен кондуктор (вид сбоку); на фиг. 2 - кондуктор в плане; на фиг. 3 - опорный узел кондуктора (в плане ) и на фиг. 4, 5 и 6 - опорный узел (вид сбоку). Кондуктор содержит каркасную раму 1, котора в поперечном сечении выполнена крестообразной. Вверху рама 1 имеет подъемные петли 2. С помощью шарниров 3 к выступам рамы 1 присоединены по периметру вертикальные Н-образные боковые рамки 4, включающие стойки 5 с закрепленными в их вершинах фиксирующими элементами в виде струбцин 6 дл фиксации верха монтируемых плит 7 и перемычки 8, в которых выполнены отверсти , играющие роль горизонтальных направл ющих. Перемычки 8 соедин ют стойки 5 рамок 4.FIG. 1 shows the jig (side view); in fig. 2 - conductor in the plan; in fig. 3 shows the support assembly of the conductor (in plan) and in FIG. 4, 5 and 6 - the reference node (side view). The jig comprises a frame frame 1, which is cross-shaped in cross section. At the top of the frame 1 has lifting loops 2. With the help of hinges 3, vertical H-shaped side frames 4 are attached to the projections of the frame 1, including racks 5 with fixing elements in the form of clamps 6 fixed at their peaks for fixing the top of the mounted plates 7 and jumpers 8 in which holes are made, playing the role of horizontal guides. Jumpers 8 connect racks 5 frames 4.

В отверсти перемычек 8 вмонтированы симметрично относительно стоек 5 в плане и ориентированные радиально к центру кондуктора выдвижные опорные пластины 9, заключенные с обеих сторон между неподвижно соедин ющими перемычки 8 ограничител ми 10 хода выдвижных опорных пластин 9.Sliding support plates 9, which are radially oriented towards the center of the conductor, are mounted symmetrically relative to the uprights 5 in the planes 8, and are enclosed on both sides between the bridges 8 that are permanently connecting the jumpers 8 and that have retractable support plates 9.

К каждой паре противолежащих в плане выдвижных опорных пластин 9 приварены в тавр вертикальные планки-упоры 11, к которым с помощью шарниров 12 присоединены лежащие в одной вертикальной плоскости верхние 13 и нижние 14 жесткие т гиVertical plates-lugs 11 are welded to each pair of opposing sliding support plates 9 in each plan, to which, by means of hinges 12, upper 13 and lower 14 rigid rods lying in the same vertical plane are attached.

равной длины, другие концы которых с помощью щарниров 15 присоединены соответственно к верхней 16 и нижней 17 гайкам, навинченным на ось 18, имеющую нейодвижно закрепленный к ней штурвал 19.of equal length, the other ends of which are connected to the upper 16 and lower 17 nuts with the help of pins 15, which are screwed onto the axis 18, having a steering wheel 19 fixed to it non-movably attached to it.

Кондуктор собран так, что его выдвижные опорные пластины 9 наход тс в одной горизонтальной плоскости, причем плоскость эта перпендикул рна вертикальной оси кондуктора и плоскост м, образуемым наружными поверхност ми вертикальных Н-образных боковых рамок 4.The conductor is assembled so that its sliding support plates 9 are in the same horizontal plane, and this plane is perpendicular to the vertical axis of the conductor and the planes formed by the outer surfaces of the vertical H-shaped lateral frames 4.

Стойки 5 вертикальных Н-образных рамок 4 в нижних част х имеют скосы дл облегчени установки кондуктора в стакан фундамента 20 под сборный ствол щахты лифта .The uprights 5 of the vertical H-shaped frames 4 in the lower parts have bevels to facilitate the installation of the conductor in the glass of the foundation 20 for the elevator shaft.

До начала монтажа щахты лифта кондуктор строп т за подъемные петли 2, после чего краном завод т в стакан фундамента 20 так, чтобы нижние плоскости выдвижных опорных пластин 9 возвышались над верхом стакана фундамента на 10-20 см. Затем вращение штурвала 10 (и, следовательно , оси 18, жестко св занных между собой ) привод т в движение гайки 16 и 17, которые в процессе сближени воздействуют на щарнирно св занные с ними т ги 13 и 14, а через них - на выдвижные опорные пластины 9, которые одновременно выдвигаютс за пределы наружных размеров кондуктора в плане.Prior to installation of the elevator lift, the jig sling t for lifting loops 2, after which the crane was pushed into the foundation glass 20 so that the lower planes of the sliding support plates 9 would rise 10-20 cm above the top of the foundation glass. Then the rotation of the steering wheel 10 (and therefore The axes 18, rigidly connected to each other) are driven by the nuts 16 and 17, which in the process of approaching act on the hinges 13 and 14 connected with them, and through them on the sliding support plates 9, which simultaneously extend beyond outside dimensions of the conductor in plan.

При дальнейщем опускании кондуктора последний зависает на выдвижных опорных пластинах 9, которыми опираетс на подготовленную к монтажу поверхность стакана фундамента 20. При этом риски разбивочных осей, нанесенные на выдвижные опорные пластины 9 кондуктора, совмещают с соответствующими рисками стакана фундамента 20.Upon further lowering of the conductor, the latter hangs on the sliding support plates 9, which relies on the surface of the base plate 20 prepared for installation. At the same time, the risks of center axes applied to the sliding support plates 9 of the conductor 20 are combined with the corresponding risks of the base glass 20.

Дл закреплени кондуктора в стакане фундамента 20 щтурвал 19 поворачивают в том же направлении до отказа, вследствие чего все выдвижные опорные пластины 9 одновременно занимают крайнее наружное положение, а в элементах, св зывающих все противолежащие выдвижные опорные пластины 9 с осью 18, создаетс усилие распора , передаваемое через верхнюю 16 и нижнюю 17 гайки, верхние 13 и нижние 14 жесткие т ги на шарниры 12, а через них - на вертикальные планки - упоры 11, перемычки 8 вертикальных Н-образных боковых рамок 4 и на внутренние поверхности стакана фундамента 20, что позвол ет .надежно закрепить кондуктор на монтажном горизонте.To fix the conductor in the foundation glass 20, the handwheel 19 is turned in the same direction until failure, as a result of which all retractable support plates 9 simultaneously occupy an outermost position, and in the elements connecting all opposite retractable support plates 9 with the axis 18, a thrust force is created transmitted through the upper 16 and lower 17 nuts, the upper 13 and lower 14 rigid rods to the hinges 12, and through them to the vertical slats — stops 11, jumpers 8 vertical H-shaped lateral frames 4 and to the inner surfaces of the glass foundation 20, which makes it possible to reliably fix the jig on the mounting horizon.

Claims

At the same time, the vertical H-shaped side frames 4 freely rotate around the hinges 3, and the thrust force is fixed by the presence of self-locking in the system connecting all the sliding support plates 9, which is also promoted by the frictional forces arising at the contact of the extension HbiJj support plates 9 with the surface of the foundation glass 20 under the force of the body of tinplate mass. The mounted plate 7 of the elevator shaft is carefully fed by a crane to the contour and is leaned against its vertical H-shaped side frame 4, and then lowered onto the glass of the foundation 20, on which two inventory pads 2) are pre-installed, having a height equal to the thickness of the horizontal groove, but at the same time not less than the thickness of the sliding support plate 9. The plate 7 installed on the inventory pads 21 is temporarily secured with clamps 6, which allows the valve to be released. In this case, the bottom of the plate 7 is reversed using one of the existing methods, first combining the alignment risks applied to the glass of the foundation 20, the plate 7 to be mounted and the sliding support plate 9, and then checking the verticality of the ends. After that, the plate 7 is fixed in the design position in accordance with the working drawings. Similarly, the remaining plates 7 are mounted on the elevator shaft contour. After the installation of all the plates 7 on the same floor is completed, the jig of the lines and the lifting loops 2 release the clamps 6, and then through the doorway 22 in the plate 7 of the elevator shaft the installer turns the handwheel 19 in the opposite direction, the protruding parts of the sliding support plates 9, being non-cracked, they are first mixed to the center of the conductor (see Fig. 5), and with further rotation of the handwheel 19, they engage with the restraints 10 of the stroke of the sliding support plates 9, carrying along the H-shaped lateral frames 4, which turning on pyr hinges 3 are separated from the inner surfaces of the plates 7 (see. FIG. 6). In this case, the jig hangs on the slings hung on the hook of the crane, it is lifted in the manner described above, set on the next mounting horizon. This installation begins a new installation cycle with the only difference being that the upper support planes of the mounted plates 7 serve as the base for the conductor. When lifting to the next mounting horizon, the conductor is not completely removed from the shaft. The rise is carried out until the sliding support plates 9 rise 10-20 cm above the top of the previously mounted plates 7 of the elevator shaft. Such a constructive solution of the conductor allows: due to the presence of bevels in the lower ends of the uprights 5 vertical H-shaped side frames 4, as well as the possibility of changing its geometry by rotating the crankshaft 19, causing the lower ends of the uprights 5 to move simultaneously upright vertical lateral H-shaped frames 4 to the center of the conductor, to reduce the duration and complexity of the installation of the conductor on the mounting horizon; to use for the installation of its sliding support plates 9 the horizontal gaps provided by the project between the mounted plates 7 of the shaft, which does not require a change in the design of the typical plates 7 and the associated costs to ensure that the conductor support parts can be placed between them; to ensure the stability of the conductor on the installation due to the possibility of creating a thrust force in its system (achieved by rotating the handwheel 19, which, together with the axis 18, nuts 16 and 17, t 13 and 14, hinges 12, vertical slats 11 and retractable support plates 9 forms a self-braking system), as well as the presence of elongated struts 5 vertical side frames 4, which are inserted into the cavity of the elevator shaft below the level of the retractable support plates 9, therefore, under the influence of mounting horizontal loads flushes both pinching a lower end of the spatial structure; ensure the internal geometric dimensions of the elevator lift due to the presence of vertical side frames 4; easily remove the retractable support plates 9 from under the mounted plates 7, since they are non-cracked due to the fact that the thickness of the retractable support plates 9 is less than the thickness of inventory pads 21 under the plates 7, which provide the design thickness of the horizontal joints between the plates 7 of the shaft ; to ensure the continuity of the processes of extracting the sliding support plates 9 from under the mounted plates 7 and the formation of gaps between the inner planes of the 7th slab plates and the outer planes of the vertical H-shaped side frames 4 of the conductor (by rotating the handwheel 19) in order to eliminate friction forces between them in the process of lifting .ma conductor crane on the next mounting horizon; to ensure the safety of work due to the possibility of carrying out operations for extending and extracting the sliding support plates 9 by rotating the handwheel 19 through the doorway 22 in the plate 7 of the elevator shaft, during which the installer is located beyond the horizontal section of the shaft; to hold the mounted plates 7 with clamps b until they are finally fixed to the design position, which allows the mounting crane to be released quickly; carry out the relocation of the conductor wound on the next assembly horizon assembled in one lift.
