All the types of the element sets form combined series of elements, every element type within the series is built to the same module size. The individual elements of the element sets include at least one shell member (k) and at least one spacer member (t), between the spacer members (t) there are gaps forming moulds for the load- bearing monolithic frame. Among the element sets the individual elements of the wall element (1) set, the wall corner element (2) set, the wall column element (3) set and the floor element (6) set are made up of at least a single spacer member (t) or of a series of spacer members (t) positioned at least in one layer and at least in one course at a distance from each other and of shell members (k) positioned up to at least one side of these, metalwork belonging to the prefabricated element sets that may be inserted into the moulds as reinforcing inserts is formed by reinforcing rods (p), planar grid supports made from reinforcing steel (r) and/or a combination of these.
摘要:
The possibility of special lightening, insulating and reinforcing intermediate floor constructions enables fast building of semi-prefibraceted and prefabricated floor with complete insulation, bearing capacity and smaller price. Floor elements (1) and (15) are constructed to that already present steel space trusses can be placed in their channels, so that are hastened the building of intermediate floor constructions and makes them cheaper, too. They are minimum shorting at the ends and at the middle of beams, so the works below can be proceeding and the required working time is shorter. The intermediate floor construction is already insulating, so they are no need for insulating, which makes the construction cheaper and the required working time shorter. The plates (17) are enabling the increase of the height of the floor constructions, by tying two beams in the construction. Usage of distance elements (23) (35) and (48) protects the reinforcement in floor construction, so they are no need for corrosion protection.

A thermal insulation plate (1), which is manufactured from cellular plastic, and the upper surface of which comprises grooves (5a, 5b), which are arranged in two directions over the area of the entire surface. The thermal insulation plate comprises at least in part of the groove (5a, 5b) intersections a spacer (6, 6a, 6b) for installing reinforcement, which is formed from thermal insulation material as a fixed part of the thermal insulation plate.

Generally one of the best types of ceiling in terms of technical and performance in the whole world is waffles ceiling. But the necessity of implementation of false ceilings also implementation of formatting in this ceiling, increases the cost. Also control of bar is difficult and may be covered from eyes, which these are another reasons for the lack of interest for this ceiling. It is shown that moment throughout span change direction in fixed span so the best option for one way ceiling and two way ceiling are beams with I-shaped sections that generally fix the problems and disadvantages of the T-shaped section. I-shaped sections have the maximum moment, minimum weight, slip and Sound transmission.in this floor there's no need for false ceilings and formatting. In order to achieve mentioned structural shape use different blocks and mold.

Various methods and systems for forming insulating building foundations are disclosed. The methods and systems are for use with fibre-reinforced concrete and allow increased speed and ease of construction because conventional reinforcement is not required. In one embodiment, a method of forming a building foundation comprises: preparing an area of the foundation to substantially the same level; providing shuttering around the outer perimeter of the prepared area of the foundation; arranging at least a plurality of first insulating elements and a plurality of second insulating elements abutting each other within the shuttering to form a continuous layer having a flat lower surface over the prepared area of the foundation, wherein the first insulating elements have a first height and the second insulating elements have a second height which is less than the first height; connecting the plurality of first insulating elements and the plurality of second insulating elements to each other using a plurality of connectors; and pouring fibre-reinforced concrete within the shuttering. The insulating elements are connected to each other using connectors and therefore any tendency of the insulating elements to float during pouring of fibre-reinforced concrete is reduced. Other embodiments relate to the features of the insulating elements and connectors for use in forming insulating building foundations using fibre-reinforced concrete.
