A formwork apparatus for producing a wall section in fresh concrete design that includes projecting connection reinforcement elements for connecting a floor to be constructed, comprising a formwork element that includes a support structure and a forming panel supported on the support structure. The formwork element is provided on one of its edge sections with a plurality of edge recesses spaced preferably uniformly apart from one another for the connection reinforcement elements. A single forming board element or multiple forming board elements serve to reversibly cover the edge recesses when the connection reinforcement elements extend through the edge recesses. A method for producing wall sections situated vertically above one another with projecting connection reinforcement elements in fresh concrete design for connecting to a floor.

A forming system includes a frame and two forming walls. The two forming walls are positioned at a distance from each other to define a first vertical wall course. One forming wall is supported by the frame such that the one forming wall can be translated toward or away from the respective other forming wall. The frame can be raised to raise the two forming walls to be positioned to pour a second vertical course on top of the first vertical course. The translation of the one forming wall allows for the pouring of the first vertical course with horizontally extending rebar that extends through the one forming wall outside of the first vertical wall course, to tie in to a subsequently poured floor slab. The translation permits the vertical raising of the one forming wall, without striking the extending rebar, to pour the second vertical course on the first vertical course. A worker's platform is provided that is supported by the frame and vertically movable by raising the frame. The worker's platform is located below the one forming wall on a side of the one forming wall opposite the respective other forming wall and is retractable to also clear the extending rebar during raising of the frame.

An assembly and method of constructing a concrete tower is provided. The method includes steps of erecting a central pillar, mounting a platform on the central pillar, setting a slipform defining a portion of the concrete tower, pouring liquid concrete from the platform into the slipform, and leaving the liquid concrete to solidify in the slipform. The slipforming repeats to form further portions of the concrete tower. Each of the further portions of the concrete tower is formed on top of a preceding one of the portions of the concrete tower. The assembly includes a central pillar, at least one slipform and a platform mountable on the central pillar and comprising means for pouring liquid concrete into the at least one slipform.

A self-climbing formwork has a stationary climbing shoe (18) structured for attachment to a wall anchor point and a climbing cylinder (10) having a lower end directly contacting the climbing shoe (18) to form a hinge, the hinge defining a pivoting movement of the climbing cylinder (10) relative to the climbing shoe (18). A support (30) is provided on an upper end of the climbing cylinder (10), the support (30) having a protrusion defining a U-shaped recess. A climbing rail (22) is structured to be held in position by the climbing shoe (18) relative to the anchor point and guided along the wall through cooperation with the climbing shoe (18). Upon extension of the climbing cylinder (10), the support (30) engages beneath an upper engagement point (24″, 24″) of the climbing rail (22) at the U-shaped recess to urge the climbing rail (22) in an upward direction.

摘要:
A constructing method for a concrete cylinder of a construction steel bar of a high-rise steel structure adopts a constructing method of supporting inside and climbing outside. The outside of the cylinder adopts hydraulic mutual-climbing adhesive lifting scaffold creeping formwork system (100), and also has an outside wallboard mechanical formwork erection function and an outer frame protection function. For the inside of the cylinder, except that an appropriate structure is left for later processing according to a schedule requirement, beam walls all adopt a steel cylinder support to perform formwork erection, so as to greatly reduce the workload of repeatedly mounting/dismantling the scaffold and the formwork at a high place. The scaffold itself carries the formwork erection system, so formwork erection and formwork removal can be mechanized, thereby reducing the risk of formwork erection and formwork removal at a high place

The climbing system comprises an upper head (5) attached to the bracket arrangement (3) and also solidly joined to the body of a hydraulic cylinder (6) the rod whereof is attached to a lower head (7), both heads (5) and (7) having a body (8) with upper (9) and lower (10) wings defining there between guides that encircle the upright (1), each of the heads having a rocker (11) that can act on flanges or blocks (14) distributed along the upright (1). The rocker is mounted on a transversal axis (12), against the action of a spring (13) that permanently acts on the rocker in any of its operating positions, and there is an outer handle (19) solidly joined to the transversal axis (12), which can make said axis (12) rotate to change the position of the rocker in relation to the upright (1). The system also has a safety device that makes it possible to limit the positions of the rocker.
摘要:
An apparatus is used to support and move vertically an erected form assembly during the construction of a building with a plurality of stories. The stories include a lower story and an upper story. Each of the lower and upper stories is formed previously with a concrete wall structure that has surrounding walls formed integrally with reinforced horizontal beams which confine an interior space. The apparatus includes a form support body that can extend across the interior space of the upper story and that has a top side on which the erected form assembly can rest. A plurality of legs extend downwardly from the form support body. Each leg has a lower portion associated with a clamping unit in order to fix releasably the leg to one of the reinforced horizontal beams of the lower story. A horizontal support bar is located below and is spaced from the form support body. The horizontal support bar can extend across the interior space of the lower story and has two ends to be mounted releasably on the reinforced horizontal beams of the lower story. A moving unit, which is connected to the form support body and the horizontal support bar, is used for moving vertically the horizontal support bar with respect to the form support body.
摘要:
A carrier having (a) a frame having a middle portion transversely formed between two lateral portions attachable to and detachable from a layer of wall formed between two shutters, the lateral portions having a length more than twice as great as the height of the shutters and (b) a rectilinear elevator operatively linked to the middle portion of the frame so that the frame is slidable upwards and downwards by means of the elevator. The elevator moves itself upwards relative to the frame when the lateral portions of the frame are attached to a first layer of wall so that the frame carries workers who install shutters between which concrete is grouted for a second layer of wall. The elevator moves the frame upwards relative thereto when the second layer of wall solidifies so that the lateral portions of the frame can be detached from the first layer of wall and attached to the second layer of wall and that the elevator can move itself upwards relative to the frame. Thus, it is possible to grout concrete between shutters for higher layers of wall by repeating the above-defined steps.
