Description

[0001] Support column

[0002] The invention relates to a support column for a climbing mast of a stationary concrete distribution device, with at least one mounting arrangement for fixing the support column to a floor of the building to be completed with the concrete distribution device, wherein the support column is designed to be arranged in rectangular cutouts of the floor, wherein the mounting arrangement has a plurality of guide elements which can be fixed in the cutout between the floor and the support column via wedges of the mounting arrangement.

[0003] Such a support column is known from WO 2008 / 025582 A1 and is used for the construction of multi-story concrete buildings. The support column is part of a climbing mast, which is formed from the support column and an articulated mast rotatably mounted on the support column. The articulated mast, consisting of mast segments that can be pivoted relative to one another, has concrete delivery lines and a connected end hose at the mast tip, which is moved by the articulated mast to distribute concrete on a floor slab of the building to be poured. The climbing mast is part of a stationary concrete distribution device, which is formed from the climbing mast and a stationary concrete pump, whereby the concrete pump pumps the concrete to be distributed on the floor slab of the building to be poured through the concrete delivery lines to the end hose.The support arrangement in WO 2008 / 025582 A1 relies on several guide elements arranged as guide plates with rectangular notches at the corners of the rectangular cutouts in the floor slabs. The support column is guided along the notches in its edge area. The guide plates are fixed in the cutout between the floor slabs and the support column via wedges of the support arrangement. For this purpose, the outer areas of the support column adjacent to the edges of the notches run parallel to the notches. The resulting essentially square cross-section of the support column is very unfavorable from a static point of view and results in very heavy support columns.

[0004] It is therefore an object of the invention to provide a lighter, in particular statically more favorable support column which enables easier fixing of the support column to a floor via an improved mounting arrangement.

[0005] This object is achieved by a support column having the features of claim 1.

[0006] Because the guide elements are designed to be arranged on one long side of the cutout, with the guide elements being supported on the support column by clamps to prevent them from slipping sideways, a lighter, more statically favorable support column can be achieved, which enables the support column to be fixed more easily to a floor using the bracket arrangement. The arrangement of the guide elements on one long side of the cutout enables a more flexible design of the cross-section of the support column, which can save weight. By arranging the guide elements on one long side of the cutout, a more statically favorable structure of the support column can be achieved. The use of clamps to secure the guide elements against lateral slipping on the support column makes the arrangement of the guide elements on one long side of the cutout secure.

[0007] The clamps prevent the guide elements from moving sideways away from the support column. The clamps prevent the guide elements and the wedges contained within them from slipping sideways. This prevents rotation and / or twisting of the support column around its longitudinal axis. The rotation of the articulated mast creates lateral forces in the support column, which could otherwise cause the guide elements and wedges to slip, causing the wedges to fall out and the support column to no longer be securely centered in the cutouts.

[0008] Advantageous embodiments and further developments of the invention emerge from the dependent claims. It should be noted that the features listed individually in the claims can also be combined with one another in any technologically expedient manner, thus revealing further embodiments of the invention.

[0009] According to an advantageous embodiment of the invention, the support column is placed on at least one guide element via at least one support device of the mounting arrangement. Placing the support column on a guide element allows the weight of the support column to be distributed via the support device in the guide element. The guide element distributes the weight force across the floor so that the permissible surface load is not exceeded.

[0010] Particularly preferred is an embodiment in which the support device has support surfaces oriented at right angles to one another, with a handle for handling the support device arranged at the angle between the support surfaces. Using the right-angled support surfaces, the support device can be positioned adjacent to the outside of the support column and projecting at right angles. The handle simplifies handling during manual transport of the support device, for example, to the next higher floor. Furthermore, the angled handle serves to reinforce the support device between the support surfaces.

[0011] A particularly advantageous embodiment of the invention relates to the guide elements each having two handles for handling the guide elements, with a support surface for the carrying device provided between the handles. The handles simplify handling of the guide elements during manual transport of the guide elements, for example, to the next higher floor. The support surface for the carrying device formed between the protruding handles prevents the carrying device from slipping on the guide element.

[0012] A particularly advantageous embodiment of the invention provides that the support device is mounted in a receptacle of the support column via a bolt and secured in the receptacle with a locking pin. The load of the support column can be transferred to the support device via the bolt in the receptacle of the support column. The locking pin on the bolt of the support device secures it against slipping out of the receptacle.

[0013] An advantageous embodiment of the invention provides that the guide elements have a stop block with at least two bevels, each of which guides a wedge toward the support column. The stop block distributes the contact force of the wedges evenly across the long sides of the ceiling cutouts, and by guiding the wedges in the beveled receptacles of the stop blocks, lateral slippage of the wedges can be effectively prevented. Guiding the wedges toward the support column ensures stable fixation of the support column in the cutout of the floor slabs.

[0014] A particularly advantageous embodiment of the invention provides that the support column has an octagonal cross-section, with the guide elements being arranged on the outer sides of the support column facing the long sides of the cutout. The octagonal cross-section offers a structurally almost optimal structure while simultaneously providing a sufficiently large support surface for the mounting arrangement. By arranging the guide elements on the outer sides of the support column facing the long sides of the cutout, the support column can be easily fixed to a floor slab. The octagonal cross-section of the support column is close to the statically even better circular cross-section, but at the same time offers outer sides oriented parallel to the long sides of the cutout, against which the wedges of the mounting arrangement can rest securely.

[0015] An advantageous embodiment of the invention provides that the mounting arrangement comprises several clamping levers that can be screwed into the guide elements, by means of which the guide elements are clamped to a floor. The clamping levers can be used to secure the guide elements to the floor against falling. This is particularly useful when the support column is not yet seated in the cutout between the guide elements. The guide elements are preferably fixed to the floor cutout by two clamping levers equipped with high-helix screws. The clamping levers can be welded or screwed to the high-helix screw.

[0016] Further features, details, and advantages of the invention will become apparent from the following description and the drawings, which show an exemplary embodiment of the invention. Corresponding objects or elements are provided with the same reference numerals in all figures. They show:

[0027] A support column according to the invention is schematically shown in Figure 1, designated by reference numeral 1. The support column 1 is part of a climbing mast 2, which is formed from the support column 1 and an articulated mast 23 rotatably mounted on the support column 1, wherein the articulated mast consists of mast segments that can be pivoted relative to one another and a turntable. A concrete delivery line 26 is guided along the articulated mast 23, and an end hose 24 is connected to the mast tip and is moved by the articulated mast 23 to distribute concrete on a floor slab D of the building G that is to be poured. The climbing mast 2 is part of a stationary concrete distribution device 27, which is formed from the climbing mast 2 and a stationary concrete pump 3, wherein the concrete pump 3 pumps the concrete to be distributed on the floor slab D of the building G that is to be poured through the concrete delivery lines 26 to the end hose 24.The support column 1 is assembled on the construction site from several individually easily transportable column sections 25. The support column 1 is arranged in rectangular cutouts A (Fig. 2) of the floor slabs D. It has several mounting arrangements 4 for fixing the support column 1 to the already completed floor slabs D of the building G to be completed with the concrete distribution device 27. After completion of a floor slab D, the support column 1 is moved upwards by at least one floor height in order to then be able to concrete the next floor slab D. For this reason, the arrangement is referred to as a climbing mast 2. It "climbs" upwards, so to speak, with the construction progress.

[0028] Figure 2 shows the support column 1 in the rectangular section A of a floor slab D. While the upper half of Figure 2 shows a sectional view through the support column 1 in the section A, the lower half of Figure 2 shows a perspective view of the support column 1 in the section A of a floor slab D. As can be clearly seen in Figure 2, the support column 1 has an octagonal cross-section 20 and supports the concrete delivery line 26, which runs vertically in a corner of the section A and is guided by the support column 1. Figure 3 shows the support arrangement 4 in more detail. The support arrangement 4 has a plurality of guide elements 5. These guide elements 5 are fixed in the section A (Fig. 5) between the floor slabs D (Fig. 1) and the support column 1 by means of the wedges 6 shown in the support arrangement 4. The guide elements 5 each have two handles 14 for handling the guide elements 5.Using these handles 14, the guide elements 5 can be easily carried to a higher floor after disassembly, where they can be reassembled to secure the support column 1 (Fig. 1). The mounting arrangement 4 comprises a plurality of clamping levers 22 that can be screwed into the guide elements 5. These clamping levers 22 can be used to clamp the guide elements 5 to the floor slabs D (Fig. 8). In the exemplary embodiment, two clamping levers 22 are provided per guide element 5, ensuring stable fixation of the guide elements 5 to the floor slabs D (Fig. 8).

[0029] Figures 4 and 5 show the support arrangement 4 according to Figure 3 between the support column 1 and the floor slab D. Here it can be seen that the guide elements 5 are arranged on the outer sides 21 of the support column 1 facing the long sides L of the cutout A. The guide elements 5 are arranged on a long side L of the cutout A. The guide elements 5 are supported on the support column 1 via clamps 7 to prevent them from slipping sideways 8. The clamps 7 enclose the outer profile of the support column 1, but are still a short distance from the surface of the support column 1. If the guide elements 5 are to be displaced sideways due to twisting or rotation of the support column 1, which occurs in particular when the articulated mast 23 arranged at the upper end of the support column 1 rotates, the clamps 7 prevent the guide elements 5 from being displaced so far that the wedges 6 would fall out.

[0030] Figure 7 shows a rear view of a guide element 5 of the mounting arrangement 4 (Fig. 3). Here it can be seen that the guide elements 5 have a stop block 28, each with two bevels 19, on each of which a wedge 6 (Fig. 3) is guided in the direction of the support column 1 (Fig. 6). The stop block 28 serves to distribute the contact force of the wedges 6 driven in between the support column 1 and the longitudinal edges L of the ceiling cutout A evenly over the longitudinal edges L. The guidance of the wedges 6 (Fig. 3) in two groove-shaped receptacles of the guide elements 5 or the stop blocks 28 effectively prevents the wedges 6 (Fig. 3) from slipping sideways. The bevels 19 of the groove-shaped receptacles press the wedges 6 (Fig. 6) in the direction of the support column 1 (Fig. 5), which enables a stable fixation of the support column 1 in the cutout A (Fig. 5) of the floor slabs D (Fig. 4).

[0031] Figure 8 shows a side view of a guide element 5 of the mounting assembly 4 (Fig. 3). This view clearly shows how the clamping levers 22, which can be screwed into the guide elements 5, clamp the guide elements 5 to a floor D. To do this, the clamping levers 22 are screwed through the guide elements 5 to the floor D until the clamping levers 22 rest against the floor D and the guide elements 5 clamp to the cutout A of the floor D.

[0032] Figure 9 shows, in addition to a fixed guide element 5 of the mounting arrangement 4 (Fig. 3), a receptacle 17 of the support column 1. This receptacle 17 is arranged on one of the outer sides 21 of the support column 1 facing the long sides L (Fig. 5) of the cutout A (Fig. 5). Corresponding receptacles 17 can be arranged in two opposite outer sides 21 of the support column 1 facing the long sides L (Fig. 5) of the cutout A (Fig. 5). Advantageously, corresponding receptacles 17 are provided in all outer sides 21 of the support column 1 facing the long sides L (Fig. 5) of the cutout A (Fig. 5). Several receptacles 17 can also be provided along the vertical extent of the support column 1.

[0033] Figure 10 shows a carrying device 9 of the mounting arrangement. The weight of the support column 1 can be supported on the floor by means of this carrying device 9. The carrying device 9 has two support surfaces 10, 11 oriented at right angles to one another. A handle 13 for handling the carrying device 9 is arranged at the angle 12 between the support surfaces 10, 11. The handle 13 facilitates the manual transport of the carrying device 9, for example to a higher floor. The carrying device 9 is received in the receptacle 17 of the support column 1 via a bolt 16 and secured in the receptacle 17 with a locking pin 18. For this purpose, the carrying device 9 can be inserted into the receptacle 17 with the bolt 16 and then rotated around the bolt axis in the receptacle 17.

[0034] Figure 11 shows a support device 9 mounted in the receptacle 17. To support the support column 1, the support device 9 is placed on a guide element 5 of the mounting arrangement 4 (Fig. 3). For this purpose, a support surface 15 is provided between the handles 14 of the guide element 5, which can also be clearly seen in Figure 9. The guide element 5 distributes the weight of the support column 1 on the floor slab D so that the permissible distributed load is not exceeded. Advantageously, several, in particular two, support devices 9 are used to support the support column 1. If two support devices 9 are used, these are arranged on the support column 1 opposite one another in the receptacles 17 of the support column 1 in order to achieve an even distribution of force in the support column 1.

[0035] For fixing the support column 1 by means of the support arrangement 4 in the ceiling cutout A, the support column 1 is first placed on a floor D with the support devices 9 arranged, for example, on two opposite sides of the support column 1 and the support column 1 is then fixed laterally in the cutouts A of the floor D with the guide devices 5 and the wedges 6.
