It is essential to the invention that the cement box has at least one integral marking, which can be used to position the cement box in a recess in a floor.

Description

The present invention relates to a cement box, which is to be arranged and fixed in a recess of a floor in order to accommodate a device, such as a floor spring, can. With the help of markings, the cement box can be aligned in the recess of the floor, whereby the device is already aligned approximately when positioned in the cement box.

The DE 103 39 333 B4 discloses a bottom door closer surrounded by a cement box anchored in a recessed recess. Towards the top, the entire cement box with the bottom door closer located therein is covered by a cover plate, so that only the cover plate can be seen from the outside. In this case, it is necessary that the floor spring in the cement box can be adjusted in all four directions in the plane, the plane being the XY plane. This has the disadvantage that the lack of reference points, the installation of the cement box is inaccurate. This may result in a cement box inserted into the recess of the floor being improperly positioned, thereby rendering it insufficient to adjust the floor spring in the plane, in order to ensure safe operation of the floor spring in conjunction with a corresponding door. The position of the cement box in the XY plane can only be roughly estimated.

It is therefore the object of the present invention to overcome the above-described disadvantages of the prior art. In particular, it is the object of the present invention to increase the installation accuracy of the cement box and thereby the Adjusting the device in the cement box to keep low, so that the function of the device is given in conjunction with a corresponding door.

The above object is solved by the features of claim 1. Further advantages, features and details of the invention will become apparent from the dependent claims, the description and the drawings.

The cement box according to the invention has at least one integral marking, which can be used for positioning the cement box in a recess of a floor.

This solution has the advantage that the cement box is to be aligned by means of the at least one integral marking in the depression of the soil so that the cement box can be brought into a position in which the device to be inserted into the cement box, for example a floor spring, Almost exactly aligned. Here, for example, the fitter compares circumferential edges of the depression with the mark and positioned the cement box according to the recess. The marking is thus used as a reference point to position the cement box. With the aid of measuring aids used today in construction, for example a cross laser, the cement box can be aligned in the recess of the floor due to the markings in the XY plane exactly to an upper pivot point at which the door to be used later has its upper pivot point , The lower pivot point of the door to be used later is the axis of the bottom door closer on which the door is placed. The cross laser can in this case be positioned such that it is arranged in the region of the upper door bearing, wherein this positioning of the cross laser with the upper pivot point of the door to be actuated matches. The cross laser radiates vertically into the depression of the floor and locally represents the point at which the axis of rotation of the floor spring will be arranged in a later assembly step. For example, the cross laser can be used such that the installer moves the cement box in the recess in the XY plane until the correspondingly adjusted laser beams coincide with the one or more marks and thus coincide, thereby positioning the cement box. In Lagerichtiger position now the cement box is attached to the building. The fixed cement box then forms an abutment for receiving the door weight forces and the door closing mechanism. Due to the positioning of the cement box in the recess of the floor, an adjustment of the floor spring in the cement box in all four directions of the XY plane is no longer required by the installer. If, nevertheless, an adjustment of the bottom door closer in the cement box are necessary, the adjustment is only required to a very small extent, which is located in the millimeter range. With the aid of the at least one marking in conjunction with a cross laser, the positioning of the cement box in the recess of the floor in the XY plane in a respective range is between 0.5 mm and 10 mm, preferably between 0.5 mm and 5 mm, particularly preferably between 0, 5mm and 2mm can be arranged.

It is advantageous that at least one mark can be arranged in the region of the height level, wherein the height level represents the height of the cement box. The markings in the area of the height level are during the insertion of the cement box in the recess of the floor for the fitter mostly steady in the field of view, whereby he can align the markers compared to reference points, which are in the immediate vicinity of the recess of the Floor can be located, such as parallel edges of the depression or with additional technical help such as using a cross laser and their laser beams. These markings can be arranged in a plane parallel to the base plate.

Furthermore, it is advantageous that the walls have a wall thickness which is penetrated by the marking and / or the marking can at least partially protrude into it. Such markings can be easily introduced in the manufacture of the cement box in the respective wall thickness and offer the fitter compared to reference points an easy way to make the alignment of the cement box in the recess of the soil. The wall thickness of the cement box can be designed depending on the material to be used for stability of the cement box to ensure the dimensional stability of the cement box.

It is also advantageous that at least one mark can extend from the height plane in the direction of the base plate into the height plane such that the height level is interrupted by the marking. Thus, when using a laser during the alignment of the cement box in the recess of the soil, the cement box can be adjusted in the recess until a laser beam coming from above meets the corresponding marking as described above, whereby the alignment of the cement box in the recess of the soil is done.

Advantageously, at least one pair of markings may be arranged in pairs opposite each other in the region of the height plane substantially transversely, preferably at an angle of 90 ° to a central axis of the cement box. When using in pairs up the height level opposite markers, two laser beams from the cross laser can be used to perform the alignment of the cement box in the recess of the soil can, the cement box is aligned as soon as the two marks are congruent with the respective associated laser beams. As a result, the installer is given the opportunity to align the cement box in the recess of the floor using a corresponding cross laser to be able to adjust the cement box in all four directions in the XY plane. It is also conceivable that more than two markings are used to perform the alignment of the cement box in the depression of the soil.

Also, advantageously, a few of marks may be arranged centrally or off-center of the longitudinal extent of the cement box in the region of the height level, which can be used for positioning the cement box in the recess of the soil. For example, depending on the setting of the laser beam device and thus its laser beams, the cement box with these markings can also be aligned in a simple manner in the recess of the soil.

Furthermore, it may be advantageous that the pairs of opposing markers are in the longitudinal extension of the cement box, wherein the paired opposing markers between the walls of the longitudinal extension of the cement box in the region of the height level are arranged, which can be used for positioning of the cement box in the recess of the soil are. For example, depending on the setting of the laser beam device and thus its laser beams, the cement box with these markings can also be aligned in the recess of the soil in a simple manner.

Advantageously, parallel spacings may be present between the longitudinal wall and a first plane and a second plane of the markings, which spacings form a first position dimension (A) and a second position dimension (B). For the kinematics of a floor spring, a so-called rear axle size is important, which is dependent on the door fittings used. The first position dimension A thus forms a first Hinterachsmaß, wherein the second position dimension B forms a second Hinterachsmaß, wherein the first Hinterachsmaß and the second Hinterachsmaß include different dimensions. The alignment of the cement box in the recess of the floor using these markings ensures that the important for the bottom door closer Hinterachsmaße can be met.

The first position dimension A can be between 46 mm and 56 mm, preferably between 49 mm and 53 mm, particularly preferably between 50 mm and 52 mm, wherein the second position dimension B can be between 60 mm and 70 mm, preferably between 63 mm and 67 mm, particularly preferably between 64 mm and 66 mm. Using these spacings from the front wall to the markings of the corresponding positions and with appropriate alignment of the cement box using the respective markings, the kinematics of the bottom door closer to be used is ensured.

The shape of the marking can advantageously be V-shaped and / or square and / or rectangular and / or semicircular and / or circular-arc-shaped and / or slot-shaped. These forms of marking are easily produced in or on the wall of the cement box in the manufacture of the cement box.

The at least one marking can advantageously be punched and / or embossed and / or notched and / or compressed and / or printed and / or glued. Here are ways of attaching marks to the cement box, which can be done individually.

Furthermore, it may be advantageous that a marking is arranged on or in the base plate. The base plate of the cement box provides a larger area for attachment of markings, whereby, for example, the pivot point of the axis of the bottom door closer can be used as a point for alignment of the cement box in the recess of the soil. This point is the reference point for a vertical orientation of the door to be used, wherein the felling of the solder can also be done with conventional tools and / or by a laser.

It may also be advantageous that the marking is stamped on and in the base plate and / or stamped and / or notched and / or compressed and / or printed and / or glued. There are possibilities of attaching markings to the base plate of the cement box, which can be done individually.

A further advantage may be that the marking is assigned on or in the base plate, a further marking, which are arranged in pairs opposite to or in the base plate. When using markers opposing each other in or on the base plate, two laser beams can be used by the laser beam device, which is aligned prior to positioning of the cement box to allow positioning of the cement box in the recess of the floor the cement box is aligned as soon as the two markings are congruent with the respective associated laser beams. It is also conceivable that more than two markers and a corresponding number of laser beams are used to perform the positioning of the cement box in the recess of the soil.

The markings, in particular those which are arranged on or in the base plate, can continue to serve as a position reference for other devices such as a door opening limiter or a closing sequence controller.

The Markenirungen can advantageously be arranged in a plane plane parallel to the base plate.

Further measures improving the invention will be described in more detail below together with the description of preferred embodiments of the invention with reference to the figures. The features mentioned in the claims and in the description may each be essential to the invention individually or in any desired combination.
