DE2343260A1 - Curbstone made of synthetic resin and quartz sand - has trapezoid-shaped opening running longitudinally on underside - Google Patents

Abstract

The kerbstone has the general shape of an inverted U and typically has three longitudinally aligned iron reinforcing bars in its upper half. Alternatively a fibrous inlay can be similarly incorporated and greatly increases the compressive strength of the structure. One end of the stone has a depression while the other has a correspondingly shaped projection so that neighbouring stones can be keyed together. A drainage water plate can be integrally cast with the stone and projects outwards and sideways from the bottom of one wall of the stone.

Patent application RESIN CONCRETE EDGE STONES

description

I.

The concrete kerbstones constructed by us will be like the already known ones Constructions from another manufacturer made from synthetic resin and quartz sand. But they differ from those already known Products in their design and economic usability. This is especially true with regard to the use of the curb as a waste water drainage pipe included in the description of the already known product; however, such use is not feasible for this product for the following reasons:

a) Each kerbstone is placed on ready-mixed concrete that is still liquid or wet relocated; the wet concrete automatically squeezes into the cavities on the inside. The remaining cavity is then too little for water to run off.

b) The curbs must be lined up with a distance of 1 cm (expansion capacity of the substructure and the superstructure). The resulting joints must be filled with concrete or another expansion material after laying. The grouting must be total height and width of the stone make up the flow is automatically interrupted.

c) The inlet slot for dirty water provided in the known product can only be kept very small for technical reasons (load capacity) and also not cover the entire length of a stone

extend. This automatically ensures that only a very small proportion of the dirty water can penetrate into the slot. at falling leaves will block this slot very quickly and will no longer be able to perform its intended function.

d) In addition, the water accumulated in the cavity of the stone freezes in winter with the result that the stone is deformed or even a solution from the substructure can be brought about. When using road salt, this risk increases even more, because while the chemical conversion process still has a very negative effect.

In contrast, the advantages of the forms we have developed (drawings 1-5) is very important. In detail, the following special features are claimed as new for our construction:

1) The inner shape of the stones - the outer shape is unchanged in accordance with DIN regulations - is designed so that they can be produced with relatively simple shapes in any company . As a result, the economy and thus the actual practicability is improved.

2) The outer wall is designed in a thickness that the maximum load capacity secures (DIN regulations).

) Differentiate between the synthetic resin concrete curbs, shapes 1 - 3, that we have constructed The interior design differs significantly from the familiar product. The iron mold in which the finished product will later be poured must is designed so straightforward that

a) the shape can be released from the cast piece immediately without complication;

b) the shape can be produced by anyone without great effort . ,.

509810/0143

4) In our construction, a significantly different one is omitted Design of the inner cavity the internal longitudinal and transverse struts, which are disturbing in the already known product, The risk of the stone breaking is almost eliminated.

The stone can be brought to the construction site immediately after shaping, as there is no risk of damage or destruction there is longitudinal and transverse striations, which otherwise lead to a reduction in the required compressive strength or makes a refill necessary.

5) The compressive strength of our stones is significantly increased.

According to the DIN-Vor steps, there is a certain amount for every curb Compressive strength prescribed. This is already done with our stone according to the shape no. 1 reached. The increased compressive strength, which the building authorities stipulate for certain roads with particularly heavy traffic with heavy vehicles reach our constructions according to the forms No. 2 and No. 3.

6) Another advantage of the stones we have constructed (No. 1-12) lies in the fact that it is extremely simple and straightforward to move them on the construction site. The time and cost savings are considerable, there In contrast to the well-known product, the transfer column can place the still wet ready-mixed concrete on the street in such a way that ours Stones quickly and without taking into account the water drainage that occurs in the known product is provided, press into the still wet concrete can. There is no need to consider thin-walled longitudinal and transverse ribs.

In the normal workflow, the upper half of the stone is reinforced with three concrete irons.

What is new is that the reinforcement bars are prefabricated to length here can be, as the stones are usually of even lengths to be manufactured "

Description of Figures 3 and 4
Work baluf and advantage just like with Form No. 2.

Another advantage arises from the inclusion of a non-woven fabric suitable for synthetic resin. As in other branches of industry It is well known that a nonwoven fabric in conjunction with synthetic resin increases the compressive strength of the finished product very significantly.

Figure No. 4 is a variation on Form No. 1 represents; otherwise no change.

Description of Figure 5

Thin-walled synthetic resin concrete kerbstones, square on the inside, at where the heads are designed as a fold on one side and as an overlap on the other side of the head. Again, the new is here extremely simple and practicable production of both the mold and of the finished product.

Description of Figure 6-9

The stones are with a fold on the left head end and an overlap on the right Head end equipped.

Nou is the advantage here, which lies in the fact that the individual stones overlap one another and therefore the subsequent grouting is only necessary by pouring out the upper edge that remains a few mm. Achieved This saves a lot of time and saves a lot of grout.

Description for figure Io

Making a stone with a circular opening in the inside, the sicli moves along the entire length of the stone.

The synthetic resin concrete curb constructed by us can also be used with an already Adhesive on the market can be glued directly onto the completed roadway. This eliminates all concrete work and the Road can be completed in one go.

Description of Figures 11 and 12

The production of the curbs, combined with an open sewer slab, is new in a cavity according to drawing no. 1 - lo. The sewer plate can be produced in any width and at any time be adapted to the local conditions or the regulations of the road construction authorities.

The kerbstones with sewer plate can also be folded and Overlap can be made (Figure No. 12).

The presented innovations and advantages of our constructions mean a significant advance both in production and in practical use compared to the previously known models. With our constructions all goals of the currently possible progress have been achieved.
