Изобретение относитс к области строительства , а именно дл уплотнени бетонной смеси при возведении зданий и сооружений в скольз щ ей и лереставной о-палубках.The invention relates to the field of construction, namely for compacting a concrete mix during the erection of buildings and structures in sliding and precast decks.

Известно устройство дл уплотнени бетонной смеси, содержащее самоходную тележку с иоворотной рамой, на которой смонтирован манипул тор с глубинным подвижным виброуплотнителем 1.A device for compacting a concrete mix is known, which contains a self-propelled carriage with a rotary frame, on which a manipulator with a deep-seated vibrating compactor 1 is mounted.

Однако известное устройство не обеспечивает свободный проход глубинното вибратора в зону уплотнени бетона через сетку арматурното каркаса, т. е. непригодно в тех случа х , когда арматурный каркас состоит не только из вертикальных, но и горизонтальных стержней.However, the known device does not provide for free passage of the deep vibrator into the concrete compaction zone through the reinforcement cage mesh, i.e., is unsuitable in cases where the reinforcement cage consists of not only vertical but also horizontal rods.

Цель изобретени - обеспечение возможности прохода виброуплотнител через арматурную сетку каркаса в зону воздействи на бетонную смесь.The purpose of the invention is to enable the vibrating compactor to pass through the reinforcement mesh of the frame to the zone of impact on the concrete mix.

Это достигаетс тем, что манипул тор снабжен изогнутыми ПО радиусу в вертикальной плоскости направл ющими виброуплотнител , причем манипул тор выполнен в виде горизонтально подвижной каретки, а виброуплотнитель -в виде пакета стержней, изогнутых по радиусу параллельно направл юп1им. На фит. 1 схематически изображено предлагаемое устройство дл уплотнени бетонной смеси,This is achieved by the fact that the manipulator is provided with curved vibrator seals in a vertical plane, the manipulator is made in the form of a horizontally moving carriage, and the vibrator in the form of a package of rods bent along the radius parallel to the direction. On the fit. 1 shows schematically the proposed device for compacting concrete;

общий вид в разрезе; на фиг. 2 - то же в плане .general view in section; in fig. 2 - the same in terms of.

Устройство дл уплотнени бетона состоит из самоходной тележки 1, в центре которой имеетс винтова втулка 2 -с навинченным на нее стаканом 3, в верхней части которого установлен опорный нодшипник 4 поворотной рамы 5.The device for compacting concrete consists of a self-propelled trolley 1, in the center of which there is a screw bushing 2 with a cup 3 screwed on it, in the upper part of which a supporting bearing 4 of a swinging frame 5 is installed.

Поворотна рама 5 снабжена жестко закрепленной осью 6, обеспечивающей ее поворот в горизонтальной плоскости, причем на ней размещен манипул тор с глубинным подвилсным виброуплотнителем в виде горизонтально подвижной каретки 7 с изогнутыми но радиусу в вертикальной плоскости направл ющими 8, в которых перемещаетс глубинный виброуплотнитель, выполненный в виде изогнутого по радиусу параллельно направл ющим пакета стержней 9 с вибратором 10, жестко св занным с последним.The pivoting frame 5 is provided with a rigidly fixed axis 6, which ensures its rotation in the horizontal plane, and a manipulator with a subsurface base vibrator in the form of a horizontally movable carriage 7 with guides 8 curved but with a radius in the vertical plane, in which the depth vibrator compactor moves in the form of a package of rods 9 bent radially parallel to the guides with a vibrator 10 rigidly connected to the latter.

Claims

The package of stanchions 9 is equipped with a displacement device in the form of a U-shaped handle 11 relative to the carriage 7, whose movement on the pivot frame 5 is detected by rotating the handwheel 12, and for vertical displacements of the pivot frame 1 on the screw glass 3 there is a handwheel 13 The self-propelled trolley 1 is mounted on rails 14 mounted on the scaffolding 15 of the formwork along its boards 16 of the concreted wall 17. The device for compacting the concrete mix works as follows. When the SRI of the Self-propelled cart 1 is turned on, the device is brought to the place of compacting the concrete mix. Then, by rotating the knobs 13 and 12, the rotary frame 5 and the carriage 7 are shown in a position in which the bundle of rods 9, by moving the U-shaped handle 11 from left to right, is fed into the sealing zone, without touching the reinforcement mesh 18. By turning on the vibrator 10, the bundle The curved 9 begins to vibrate and compact the concrete mix. As the U-shaped grip 11 moves towards the reinforcement cage, the depth of the rods 9 increases, and consequently the depth of the concrete is compacted. At the end of the seal, the package of rods 9 is withdrawn from the sealing zone by moving the U-shaped handle 11 to the extreme left position. The vibrator 10 is disconnected, and the carriage 1 moves along the concrete wall 17 of mine to the adjacent sealing area. Since the frame of the formwork is encountered in the movement of the device, the turning frame 5 in the places of installation of the latter is rotated on its axis 6 at an angle sufficient for free passage of the piece, which it rotates to its original position. Further, the cycle of operation of the device is repeated. Apparatus for compacting a self-propelled trolley with a swinging frame on which is mounted a manipulator with a deep-moving mobile vibratory compactor, characterized in that, in order to allow the vibrating compactor to pass through the reinforcement cage of the frame into the zone of impact on the concrete mixture, the manipulator is made in the form of a horizontally movable carriage and provided with guides for the vibro-compactor bent along the radius in the vertical plane, and the latter is made in the form of a package rod radially curved parallel to the rails.
