Abstract

The invention is a vehicle which contains all machines and equipment on a single trailer and which may be replenished where it stands for the production and application of lightweight concrete which is obtained by mixing cement, sand, water and foam. The principal characteristic of the lightweight concrete production and application vehicle is that all components and equipment required for the production and application of lightweight concrete are mounted on a single trailer and that it may be moved by means of a towing vehicle. When the vehicle arrives at the application site, it is ready to start the production as from the moment when it extends its cab struts (21 and 22) and is immobilised. The vehicle may be replenished with materials where it stands.

INSTRUCTIONS

LIGHTWEIGHT CONCRETE PRODUCTION AND APPLICATION VEHICLE The invention is related to a vehicle which contains all machines and equipment on a single trailer and which may be replenished where it stands for the production and application of lightweight concrete which is obtained by mixing cement, sand, water and foam. Lightweight concrete which is a product obtained by mixing the foam and cement mixture obtained by mixing special foaming agents with air and water by means of machines or equipment finds so significant an area of use especially in those regions located in the seismic zone. Thanks to the air pores created by foam, it is quite lightweight and provides noise and heat insulation.

In the existing practice in the marketplace at present, concrete (that which only contains water, sand and cement) is produced at the plant and taken to the application site by a concrete mixer and mixed with foam which allows for the making of lightweight concrete by means of other machinery and equipment there. Afterwards, it is pumped to the application site by means of another pump. Concrete arrives at the application site by means of a mixer. As a result of the reactions occurring due to the time elapsing in transit, the concrete starts to set and heat up. Further, when the mixer arrives at the application site, it may not discharge all the concrete at the same time. Concrete is usually discharged into another mixer in lots of one cubic meter and application takes place by mixing a foaming agent to that quantity. Mixers usually carry seven cubic meters of concrete and the concrete in the mixer lays until it reaches the last cubic meter and keeps reacting and setting. Due to the time lost in transit and application, the concrete quality and strength reduces. No certain standard may be attained in the concrete so produced. The fact that the concrete is moved from another location by a mixer, that the mixer lays during the production, that mixing and pumping vehicles are different causes the transport costs to increase. By the vehicle covered by the invention which has been developed in order to overcome such hitches, deterioration of the concrete quality has been prevented due to the fact that the production and application of lightweight concrete may be simultaneously carried out at the application site. In the vehicle covered by the invention, the highest quality and standard has been achieved in the concrete instantly produced and pumped to the application site by the automated system. Thanks to the fact that production and application may be simultaneously carried out, time is saved and costs of application and transport are reduced. Laying and carrying problem has been overcome.

Production and application are as follows: The water tank (6) is supplied with water and the aggregate bunker (2) with sand by means of a scoop or sand belt, and cement is pumped to the cement silo by means of a cement trailer. In cases where there is no electric power from the urban network, power is supplied by a noise-insulated generator (15). Thanks to the automated system installed in the control cabinet (12), data on the product to be produced is entered in the computer system, and production starts in accordance with the formulae and recipes stored in the computer software.

Sand is weighed in the weighing group (1 ) and conveyed to the mixer (7) by means of the transfer conveyor-1 (1 1 ) and the transfer conveyor-2 (9), and the cement from the cement silo (3) by means of the conveying spiral (8) is weighed in the cement weighing bunker (4) and conveyed to the mixer (7), and the water from the water tank (6) passes through the water weighing bunker (5) and then arrives at the mixer (7). Sand, cement and water start to be mixed in the mixer (7). Afterwards, the foaming agent generator (16) pumps the foam it has generated to the mixer (7). The whole mixture has been completed in this manner. The foam forms small air pores in the concrete. The mixture so completed is discharged into the transfer vessel (19). The mixture here is then conveyed to the application site by means of the pump (17).

The principal characteristic of the lightweight concrete production and application vehicle is that all components and equipment required for the production and application of lightweight concrete are mounted on a single trailer and that it may be moved by means of a towing vehicle. When the vehicle arrives at the application site, it is ready to start the production as from the moment when it extends its cab struts [cab strut-1 (21 ) and cab strut-2 (22)] and is immobilised. The vehicle may be replenished with materials where it is immobilised.

The cement silo (3) is consisted of two cells separated from each other. From these two cells, two separate conveying spirals (8) are connected to two separate cement weighing bunkers (4). And these two cement weighing bunkers (4) are connected to the mixer (7). In this case, in the event that any failure occurs in a conveying spiral (8) or a cement weighing bunker (4), operation may be maintained without interruption from the other side. Weight of the regular concrete is approximately 2300-2400 kg/m³. But the weight of the POR concrete (lightweight concrete) covered by this invention is optionally between 200 kg/m³ and 1 .600 kg/m³. Lightweight concrete reduces the burden of buildings due to its reduced weight and further has such properties as heat insulation, noise insulation and water-resistance due to the fact that it has closed pores. The foaming agent is protein-based and does not contain any chemicals. Lightweight concrete is intended to use for grouting, pouring walls in forms and behind segments and filling.
