Definitions
- the present invention relates to a mould bulkhead, or stop end, of the kind used in moulds intended for moulding slab-like concrete elements.
- This mould will normally comprise a flat sheet or plate which has mould bulkheads permanently or fixedly attached to the edge surfaces thereof, such as to form an upstanding coaming.
- the mould is often used to cast concrete elements which are smaller than said maximum size.
- the mould is adapted to correspond to the desired element size with the aid of further bulkheads, or stop ends, which are attached to two mutually opposing bulkheads of the aforesaid permanent bulkheads.
- the present invention solves this problem.
- the present invention relates to a mould bulkhead of the kind used in moulds intended for moulding slab-like concrete elements and placed and secured transversely or longitudinally of the mould with the aid of fastener devices, which bulkhead is provided at its lower part a downwardly and outwardly extending tongue made of a softer and springy material, such as a plastics material, the tip of which, when no load acts thereon, is located on a lower level than that part of the casing undersurface which is intended to lie against the mould bottom, which bulkhead is characterized in that the bulkhead includes an aluminium profile fitted with a casing profile, where the casing includes said tongue, and in that the aluminium profile is configured with a downward bend, such that in the absence of load in use the ends of said profile will be located on a higher level than the centre thereof and in that said fastener devices are intended for attachment to permanent of fixed bulkheads along the edges of the mould, and in that the fastener devices are intended to press down the bulkhead against the mould bottom in a manner to straighten
- Figure 6 illustrates schematically a mould or form 1 which has so-called permanent bulkheads, or stops ends, 2, 3, 4, 5 extending around the perimeter thereof; see also Figures 3 and 5, of which Figure 3 is a sectional view taken on the line A-A in Figure 6 and Figure 5 is a sectional view taken on the line B-B in Figure 6.
- Figure 6 illustrates a detachable inventive bulkhead 10 which extends in the longitudinal direction of the mould 1 and a detachable bulkhead 11 which extends transversely of the longitudinal axis of the mould.
- the bulkheads 10, 11 are intended to be positioned and secured to the permanent or fixed mould bulkheads 2-5 with the aid of fastener devices 12, 13, 14.
- Figure 1 illustrates an inventive bulkhead 10, 11 in cross-section, corresponding to the cross-section C-C in Figure 6.
- the bulkhead includes an aluminium profile 15 fitted with a casing 16 which is made of a softer and springy material, such as a plastics material. Located on the lower end part of the casing 16 is a tongue or lip 17, the outer tip 18 of which, when no load acts thereon, is located at a level which is lower than that part 19, 20 of the casing which is intended to abut the bottom 22 of the mould, Thus, when the bulkhead is pressed down against the mould bottom 22, the tongue 17 wil be forced out slightly to the position 21 shown in chain in Figure 1, against its inherent spring force.
- the bulkhead is intended to be positioned so that the tongue will face towards that part of the mould which is to be filled with concrete.
- the aluminium profile is configured with a downward bend f which is greatest at the centre of the profile, seen in its length direction, so that when no load acts on the profile in its position of use the ends 23-24 of the profile will lie on a higher level than its centre, see Figure 2.
- the ratio of the downward bend f to the total length of the profile (L) is from about 5:3000 to 30:3000, preferably 20:3000.
- the aluminum profile has a rectangular cross-section, preferably with a material tickness of up to 5 mm.
- the aluminium profile is preferably formed so that in the use position of the profile the vertical parts 25, 26 of the profile will have a material thickness of about 2.5 mm and the horizontal parts thereof will have a material thickness of about 5 mm.
- this profile configuration will produce sufficient force to straighten out the profile, by forcing down the ends of the profile with the aid of fastener devices 12, 13, 14.
- the fastener devices 12, 13, 14 are thus intended to press down the ends of the bulkhead towards and against the mould bottom, so that the downward bend f is straightened totally, or substantially totally. This means that the centre parts of the bulkhead will also be pressed against the mould bottom with a given force, which is not the case with bulkheads which lack the downward bend f .
- the plastics material is a polypropylene plastic.
- the plastics material is a PVC-plastic.
- aluminium will provide a profile which while sufficiently rigid is nevertheless bendable.
- the advantage afforded by the use of a plastic casing is that a bendable or flexible tongue 17 can be formed and that concrete will not come into direct contact with aluminium. This latter advantage is also highly beneficial, since concrete adheres firmly aluminium.
- Figures 3 and 4 illustrate a fastener device, generally referenced 14, which comprises two parts 29, 30 the part 29 in Figure 4 being shown in a direction from the right in Figure 3.
- the fastener part 29 presents a claw 31 which grips around the outer edge of the permanent bulkhead 5.
- the fastener part 29 also lies against and grips around the upper part of the permanent bulkhead 5.
- the fastener part 29 is U-shaped, having two legs 32, 33 which are joined by a web 34.
- a part 30 in the form of a straight tie or brace is inserted between the legs 32, 33.
- the opposite end 35 of the tie 30 lies against the upper part of an inventive bulkhead 10.
- the tie is moved down so as to urge the bulkhead against the mould bottom.
- a multiple of such fastener devices 14 are located along a longitudinally extending bulkhead 10, as shown in Figure 6.
- FIG. 5 illustrates fastener devices, generally referenced 12, which are used preferably to secure and clamp down transverse inventive bulkheads 11.
- the fastener 12 includes two parts 37, 38, of which one part 37 has a claw 39 which grips around the permanent bulkhead 5.
- the other part 38 is a tie or brace which is attached to the inventive bulkhead by means of bolts 40, 41.
- Acting between the first fastener part 37 and the second fastener part 38 is a bolt 42 which when tightened or screwed in causes the ends of the bulkhead to be pressed down against the mould bottom.
- inventive bulkhead can be used as both a transverse and a longitudinal bulkhead.
- fastener devices can have any suitable configuration or construction, partially governed by the configuration of the mould and its edges.
- the present invention shall not therefore be considered limited to the aforedescribed embodiments, since modifications can be made within the scope of the following claims.
