Description

[0001] The invention relates to an auxiliary assembly device for fastening a spacer body to the upwardly facing underside of a floor board lying in end alignment parallel to a floor board already fastened to a supporting beam, and to a method for this purpose.

[0002] Spacers for fastening floor boards to supporting beams are known from FR 2 903 707, DE 20 2005 002 204 U1, WO 2007 / 051934 A1 and DE 10 2006 035 805 B3.

[0003] DE 10 2008 018 072 B3 shows an assembly aid for laying terrace planks.

[0004] The invention is based on the object of providing a device with which spacer elements can be fastened to the upwardly facing underside of a floorboard, so that the floorboard can be mounted in a parallel position to already fastened floorboards.

[0005] The object is achieved by the auxiliary device specified in the main claim and a method according to claim 10. The subclaims represent advantageous developments of the auxiliary device.

[0006] According to the invention, the auxiliary device has a stop for engagement with the long side of the floorboard to be fastened, which in the assembly position faces the fastened floorboard. The floorboard to be fastened is first aligned parallel to the already fastened floorboard, with its underside facing upwards. The end face of the floorboard to be fastened is brought into alignment with the end face of the already fastened floorboard. The stop of the auxiliary device, which can be formed by a wing connected to a handle section from a single material, is placed in the space between the floorboard to be fastened and the already fastened floorboard. The spacer to be fastened has previously been inserted into a receptacle of the auxiliary device. There, it extends essentially transversely to the direction of the stop, since the receptacle extends approximately at right angles to the direction of engagement of the stop.In the area of ​​the stop, adjustment lugs protrude from the underside of the auxiliary device. In principle, it is sufficient to provide at least one adjustment element that can be brought into contact with the already installed spacer element. The already installed spacer element was previously screwed to the underside of the already attached floor board. Using an under-push section, this spacer was pushed under another, already attached floor board. A rear fastening section of the spacer resting on the support beam was previously screwed to the support beam. The adjustment element is placed on this overhanging section of the already installed spacer. This means that the holder and the spacer located in the holder are laterally offset from the already attached spacer on the upward-facing underside of the floor board to be attached.In the area of ​​the receptacle, which can be formed by a longitudinal groove-like cavity, there are holding means, in particular in the form of locking tongues, which hold the spacer in the receptacle. In addition, positive engagement means can be provided to fix the position of the spacer. The position is fixed in such a way that a positioning web of the spacer to be fastened lies in the area of ​​the stop. In particular, a contact surface of the positioning web lies flush with the stop plane. Beyond the positioning web there is a fastening projection which protrudes beyond the floorboard to be fastened after installation. This projecting section is then screwed to the supporting beam as described above and forms a contact flank for the alignment lugs for the alignment of a spacer of a subsequent floorboard.To determine the position of the auxiliary device, it is first placed with the stop against the long side of the floorboard to be secured. It is then moved along the long side until the adjustment lug abuts the protruding portion of the already installed spacer. The spacer is then screwed onto the underside of the floorboard to be secured. For this purpose, the handle of the auxiliary device has at least one window through which the screws can be screwed into the mounting holes of the spacer. These screws, which penetrate the mounting holes of the spacer, secure the spacer to the underside of the floorboard to be secured.After at least two such spacers have been attached to the underside of the floorboard for attachment to two support beams, the floorboard is rotated 180° so that the underside of the floorboard to be attached points downward toward the top of the support beam. Now, a sub-section of the two spacers extending over the long edge of the floorboard is pushed under the already attached floorboard. The floorboard is screwed to the support beam in the area of ​​the overhang.

[0008] The one in the Fig. 1 to 5 shown spacer 1 and the one shown in the Fig. The spacer body 2 shown in Figures 1 to 8 is arranged in the Fig. 9 to 12 for fastening floor boards 3 to support beams 4. The support beams run parallel to one another at a distance of a multiple of their width and form the supporting structure for a floor, in particular a terrace floor, which consists of a plurality of closely adjacent and parallel curved boards 3. The floor boards 3 are fastened to the support beam 4 using the spacers 1, 2, with spacers 1 first being screwed onto the underside of the floor boards 3. The floor boards 3 are then rotated into their assembly position and fastened to the support beam 4 in a position parallel to a floor board 3 already fastened to the support beam 4. In this process, an underlay section 14, which projects beyond a long side of the floor board 3, is pushed under the already fastened floor board 3.An end of the spacer body 1 opposite the under-thrust section 14 forms a screw-on section 15, with which the spacer body 1 is fastened to the supporting beam 4 by means of fastening screws 26. .

[0009] The one in the Fig. The spacer 1 shown in Figures 1 to 5 is used to fasten the middle floor boards 3. The Fig. The spacer 2 shown in Figures 6 to 8 serves to fasten the floorboards 3 forming the edge of the floor to the supporting beam 4.

[0010] The spacer body 1 consists of a plastic injection-molded part. It has a substantially cuboidal, elongated shape. It is essentially divided into three sections: a first fastening section 5, which forms the above-mentioned under-thrust section 14, an intermediate region 6, which forms a predetermined breaking point 8 to be described below, and a fastening section 7, which forms the above-mentioned screw-on section 15. The fastening section 5 forming the under-thrust section 14 has several fastening openings 18 accessible from the screw-on side 27, into which fastening screws can be screwed if the spacer body 1 is used to fasten an edge-side floorboard 3. These fastening openings 18 are located in the under-thrust section 14, which can otherwise be pushed under the underside 3' of an already installed floorboard.The fastening section 5 also has fastening openings 20 accessible from the support side 28, into which fastening screws can be screwed in order to screw the spacer 1 to the underside 3' of a floor board 3 to be laid. For this purpose, the support side 28 forms cup-shaped recesses 23 into which the screw head of the fastening screw 25 can be screwed, as is particularly the case with the . Fig. 11 shows.

[0011] A finger 9 protrudes from the fastening section 5. The finger is not only narrower but also lower in height than the outline of the under-thrust section 14. The two longitudinal narrow sides of the finger 9, facing away from each other, are connected to tabs 10 of the other fastening section 7 by break-off webs 8, which extend between the screw-on side 27 and the support side 28. The tabs 10 originate from one end of the fastening section 7 and delimit a recess 11. The tabs 10 are extensions of the longitudinal narrow sides of the fastening section 7. The break-off webs 8 are located approximately in the center of the longitudinal narrow side of the finger 9.

[0012] Adjoining the front side of the finger 9 is a shaft 12 which extends the recess 11 and is open towards the support side 28 but closed towards the screw-on side 27.

[0013] The fastening section 7 also has cup-shaped openings 23 accessible from the support side 28, in which the cup base forms fastening openings 21. By screwing fastening screws 25 into the cup-shaped openings 23, the fastening section 7 can be fastened to the underside 3' of the base board 3.

[0014] A positioning bar 13 protrudes from the screw-on side 27. In the mounted position, this bar rests against a narrow longitudinal side of the baseboard 3.

[0015] Below the positioning web 13, on the support side 28, there is a groove 24 into which the positioning web 13 can enter to facilitate the stacking of a large number of spacers 1.

[0016] Again Fig. 4, the screw-on side 27 of the fastening section 5 forming the under-thrust section 14 also has marking grooves 17, 16 running transversely to the direction of extension of the spacer body 1. If this fastening section needs to be shortened, this can be done there.

[0017] The spacer body 1 is designed as a hollow body. The cavity is open toward the support side 28 and is divided into a plurality of compartments by a plurality of stiffening ribs 22.

[0018] In the Fig. 6 and Fig. In the spacer body 2 shown in Figure 8, there is also an intermediate section 6 with a predetermined breaking point 8 between a fastening section 5 and a fastening section 7, which has the previously described structure. The fastening section 5 can be provided with optional additional Fig. 6 indicated fastening openings 18 in order to be able to fasten this fastening section 5 also to the supporting beam 4.

[0019] The fastening section 7 has a screw-on section 15, which is angled essentially transversely to the direction of extension of the spacer body 2. The screw-on section 15 is angled relative to the support side 28 and can be screwed to the end face of a supporting beam 4. For this purpose, the screw-on section 15 has fastening openings 19, which are also formed by cup-shaped openings for receiving the screw heads.

[0020] The spacer body 2 is also designed as a hollow body and has the fastening openings 21, 20 already described above, with which the spacer body 2 can be fastened to the underside of a floor board 3.

[0021] The two previously described spacers 1, 2 are used as follows: A first floor board 3 can be attached to a support beam 4 using either a spacer 1 or a spacer 2. If the spacer 1 is used for this purpose, the under-shear section 14 can be cut to length in a suitable manner. This is done at the level of the marking notches 16, 17. The spacer 1 is first screwed to the underside 3' of the edge floor board 3. The overhanging area 14 is not used as an under-shear section during assembly of the first floor board, but rather as a screw-on section, for which purpose fastening screws are screwed through the fastening openings 18, with which the fastening section 5 is fastened to the support beam 4. A fastening screw 26 is then screwed through each of the fastening openings 19 in order to fasten the first floor board 3 to the support beam 4 on both sides.

[0022] Alternatively, the spacer 2 can also be used to fasten the first floor board. Here, too, the spacer 2 is first connected to the underside 3' of a floor board 3 by means of fastening screws 25, which are screwed through the fastening openings 20, 21. The floor board 3 prepared in this way is then placed on the support beams 4. A fastening screw is screwed into the fastening opening 19 of the screw-on section 15, which fastens the spacer 2 to the support beam 4. The other end of the spacer 2 can then be fastened to the support beam 4 through optional fastening openings 18. However, this is not necessary. One-sided fastening is generally sufficient and also allows the fastening section 5 to slide relative to the fastening section 7, breaking the predetermined breaking point 8.

[0023] The installation of the middle floor boards 3 is also carried out by mounting the spacer body 1 using fastening screws 25 through the fastening openings 20, 21 on the underside 3' of a floor board 3 to be installed. Fig. 9 indicates that this is done with floor boards 3 resting on their visible side on the support beam 4, whereby the position of the support beams 4 determines the position of the spacers 1. The spacers 1 are arranged laterally offset from one another on adjacent floor boards 3 so that a support section 14 lies next to a screw-on section 15. During the pre-assembly of the spacer 1 on the underside 3' of the floor board 3, the positioning web 13 serves as an assembly aid. It is placed against a longitudinal edge of the floor board 3.

[0024] After turning the floorboard 3 over, the underlay sections 14 projecting beyond the long side of the floorboard 3 can be pushed under the underside 3' of an already installed floorboard 3. This fixes the height of the floorboard 3 to be installed. The gap between the floorboards 3 is generally freely selectable. It can have the thickness of the positioning bar.

[0025] The screw-on section 15 extending beyond the positioning web 13 is then fastened to the supporting beam 4 by means of fastening screws 26, the heads of which are countersunk into cup-shaped recesses.

[0026] In this way, all further middle floor boards 3 are fastened one after the other to the supporting beam 4. The spacer 2 is used to fasten the last floor board 3. This is in turn screwed with its screwing side 27 to the underside 3' of the last floor board 3, so that the angled screwing section 15 is located at a suitable location to be connected to the other end face of the supporting beam 4, as shown in the Fig. 12 shown, to be screwed on.

[0027] Since the spacers 1 and preferably also the spacers 2 are only firmly connected to the supporting beams 4 by one of the two fastening sections 5, 7 and are otherwise connected to one of the broad side halves of the floorboard 3 by the two fastening sections 5, 7, the connection between the two fastening sections 5, 7, which is provided in the intermediate section 6, can become loose if the floorboard 3 expands or swings. This occurs when the break-off web 8 breaks. The finger 9 then lies freely between the two tabs 10. Since only the fastening section 7 is connected to the supporting beam 4, the fastening section 5 can move relative to the supporting beam 4. If the floorboard 3 expands, the finger 9 can, as shown in the Fig. 5, move out of the recess 11. However, if the width of the base board 3 decreases, the finger 9 can, as shown in the Fig. 4, drive deeper into the recess 11 and into the shaft 12.

[0028] The Fig. 13 to 17 describe a second aspect of the invention in the form of a spacer strip, which is first screwed onto a supporting beam 4 before laying the floorboards 3. This is done by means of fastening screws 26. The floorboards 3 are then fastened to the supporting beam 4 by means of nails or fastening screws 25, with the spacer strip 30 defining a gap between the supporting beam 4 and the floorboard 3.

[0029] The spacer strip 30 is preferably made of plastic and has a wave-like shape with positive-locking connecting means 37, 39 corresponding to each other at the ends. A positive-locking connecting means 37 is formed by a cylindrical connection opening, the wall of which has a slotted opening 38. The meandering shape of the webs 31, 32 forming the spacer strip 30 occurs in the fastening plane. The axis of the cylindrical opening 37 extends perpendicular to the fastening plane, so that its end faces lie in the support sides of the spacer strip 30.

[0030] The other end of the spacer bar 30 forms a connection head 39 in the shape of a cylinder that fits into the connection opening 37, the end faces of which also lie in the two spaced-apart, parallel wide sides of the spacer bar 30. A web 40 connects the connection head 39 to the meandering webs 31, 32 of the spacer bar 30. The web 40 is wide enough to fit into the slotted opening 38.

[0031] The previously mentioned meandering webs 31, 32 run on circular arc sections and each surround waisted bays 34, 35. The two webs 31 running on a circular arc merge into one another, forming a kink 33.

[0032] There are longer arched webs 31 and shorter arched webs 32. The longer arched webs 31 extend in a circular ring around the bay 34 at an angle of more than 180°. The shorter arched webs 32 extend around the bay 35 at an angle of less than 180°. The bay 35 is thus flanked by outer cylinder wall sections of the web 31 and forms an inner bend in the area of ​​the bend 33. In the area of ​​the bay 34, the bend 33 forms an outer bend.

[0033] The broad side surfaces 31', 32' of the webs run in common planes which run parallel to each other and which form the support sides of the spacer strip 30.

[0034] Every fifth to tenth bay 34 has a base 41 and thus forms a mounting opening 36. A mounting screw can be screwed into the mounting opening 36 through a base opening. Since the base 41 extends only over a portion of the height of the spacer bar 30, a cup-shaped opening remains to accommodate the screw head.

[0035] The Fig. 16, Fig. 17 shows how a spacer bar 30 can be extended as desired by inserting a connection head 39 into a connection opening 37 of another spacer bar 30. This thus extended spacer bar 30 is first connected to the supporting beam 4 by means of fastening screws 26 through the fastening openings 36. The floorboards 3 are then screwed onto the spacer bar 30 using fastening screws 25, which are screwed into the supporting beam 4.

[0036] For fastening the spacer body 1 described in the input or a spacer body according to the prior art to one or more supporting beams 101, an assembly aid device 122 according to the invention is provided, as shown in the Fig. 21 to 27. Their functionality is explained using the Fig. 18 to 20 described.

[0037] The assembly aid 122 is made of plastic and has an elongated rear handle portion with two adjacent windows 126, 127. A head 128 is attached to the handle portion.

[0038] In the area of ​​the head, on the underside of the plastic body 122, which forms the assembly aid, there is a stop 123 which is formed by side walls of wings 116 projecting on both sides or by one edge of an adjusting lug 125.

[0039] The two adjustment lugs 125 project downwards beyond the stop 123 and are spaced apart from each other, so that a free space 117 extends between the two adjustment lugs 125. Aligned with the free space 117, the underside of the auxiliary device 122 forms a receiving groove 124 for receiving a spacer 1.

[0040] The spacer body is essentially an elongated plastic part 1 with a plurality of fastening openings 18, 19, 20, 21 and a positioning web 13.

[0041] Approximately in the center, the spacer body 1 forms at least one lateral recess 120. The receiving groove 124 forms corresponding projections 119, each of which engages in a recess 120 to thereby fix the position of the spacer body located in the receiving groove 124 such that the positioning web 13 lies in the region of the stop 123.

[0042] The side walls of the receiving groove 124 are further flanked by retaining tongues 118 and 121 in order to hold the spacer body 1 in a form-fitting or friction-fitting manner within the receptacle 124.

[0043] The windows 126 and 127 mentioned above are located above plank fastening openings 20 and 21 respectively, so that they are freely accessible.

[0044] As in particular the Fig. 26, the adjusting lugs 125 are projected above the head 128. The adjusting lugs 125 consist of flat plastic tabs that run parallel to each other. Fig. As can be seen from Figure 20, the two wings 116 forming the stop 123 are integrally formed with the handle body and, like the handle body, are also designed as hollow bodies. The two wings 116 are separated from one another in the cavity forming the receptacle 124 and project below the support side of the auxiliary assembly device 122 by approximately half the material thickness of a floorboard 107 to be attached. The two adjusting lugs 125 extending parallel to one another are formed by extensions of the inner side walls and wings 116 and project below the underside of the wings 116. The material thickness of the adjusting wings 125 defines the distance between the two spacers lying adjacent to one another in an overlapping manner on the support beam 101.

[0045] The assembly aid works as follows: The Fig. Figure 18 describes an assembly position in which two floor boards 102 are already attached to a supporting beam 101, each with two spacers 112. The spacers 112 are screwed to the underside 104 of the floor board 102, so that the upper side 103 protrudes upward. The spacers 112 are also connected to the supporting beam 101 by means of fastening screws screwed into the overhang section 115. In the area of ​​the overhang section 115, two adjacent spacers 112, each belonging to a different floor board 107, overlap, so that an under-shear section 114 lies next to a spacer 112, and an overhang section 115 lies next to a spacer 112.

[0046] The floorboard 107 to be fastened is placed with its upper side 108 facing down on the upper side 101' of the supporting beam 101 such that its edge 111 runs parallel to the edge 106 of the fastened floorboard 102. The two end faces 105 and 110 of the two floorboards 102, 107 are aligned. Since the floorboard 107 to be fastened abuts the overhang section 115, a gap is formed between the two long sides 111 and 106.

[0047] The two wings 116 of the assembly aid 122 are inserted into this longitudinal gap and the surface of the stop 123 is brought against the longitudinal side 111. The assembly aid, in whose receptacle 124 a spacer 1 is inserted, is then pushed along the longitudinal edge 111 until the adjusting lug 125 abuts the projection section 115 of the already mounted spacer 112, as is the case, for example, with the Fig. 20 shows.

[0048] The fastening screws are then screwed through the two windows 126, 127 through the fastening openings 20, 21, so that the spacer 112 is firmly attached to the upwardly facing underside 109 of the floorboard 107. The positioning web 13 rests against the long side 111.

[0049] The floorboard 107 to be attached is then rotated 180° so that its underside 109 faces downward. The spacer 1, now positioned at the bottom, is placed on top of the support beam 101. The spacer 1 now lies next to the already attached spacer 112, so that its underlay section 14 can be pushed under the underside 104 of the already installed floorboard. By screwing fastening screws into the openings 19 of the screw-on section 15, the floorboard 107 is also attached to the support beam 1.

[0050] The next floor board 107 to be fastened is fastened in the same way, but now the spacer 1 is on the other side of the already fastened spacer.
