Abstract

The invention relates to the field of construction and can be used for the manufacture of reinforced concrete structures of buildings and structures. The purpose of the invention is to increase the strength of the manufactured building structure due to the additional anchoring layer 2 formed at the inner surface of each formwork plate 1 by 3 fibers protruding from concrete, which are part of the bulk fibrous frame of the formwork plate having anchor outlets 5. 5 ill.

Description

The invention relates to construction and is intended for the manufacture of building structures and structures.

The aim of the invention is to increase the strength of the building structure.

Figure 1 shows a portion of the fixed fiber-reinforced formwork, cross section; Fig. 2 illustrates the moment of completion of the filling of the form for the manufacture of the formwork plate with fiber and the formation of a fibrous frame in it; FIG. 3 shows the process of introducing the concrete mixture into the lower part of the volume of the fibrocarcass using the vibrating method; Fig. 4 illustrates the end of the entry of the concrete mixture into the lower part of the fibrocarcass volume; Fig. 5 illustrates the moment of completion of the form stripping with the fiber-reinforced concrete formwork plate of the permanent formwork of the proposed construction.

Fixed fibrobetonna. The formwork for the construction of a building structure includes thin-walled fiber-reinforced concrete formwork plates 1, an additional anchoring layer 2 at the inner surface of each slab, formed by fibers protruding from Concrete 3, which are part of the bulky reinforcing frame of the formwork plate, fastening elements 4 and anchor outlets 5.

Fixed fiber concrete formwork is made as follows.

First, formwork plates 1 are made by separate stacking of the components (fibers and concrete mix). To do this, form 6 is placed on the vibrating table 7. Fibers are applied to form B, which forms the fibrocarcass in it. Then, anchor outlets 5 are installed in the fiber box. Separately, prepare a mobile fine-grained concrete mix 8 made of fine sand, cement, water and a plasticizer, for example, C.-.). The prepared concrete mix 8 is placed on the fibrocarcass. The working body of the vibrating table 7 is turned on. Under the force of gravity, as well as vibrations from the working body of the vibrating table 7, the concrete mixture fills in the form of the lower part of the volume of the fibrous frame (the cell between the fiber). Then, the concrete mixture in the form and the cells of the fibro-frame hardens under normal conditions or during the process of thermo-moisture treatment in the steaming chamber. In this case, one end of each fiber is anchored in concrete 3 of formwork board 1, the other

located in the space between the formwork plates, as a result of which an additional anchorage layer 2 forms at the upper surface of each plate, which is filled with concrete or other material during the process of laying the latter into the space between the formwork plates 1 during the construction of the building structure. After the concrete is set to one hundred percent strength (after 28 days of hardening under normal conditions or after 8 hours of steaming at + 60 ° C and a humidity of 100%), form 6 is dismantled with formwork plate 1.

In the specified technological sequence make the second and subsequent. Fiber concrete formwork plates 1 of the proposed construction.

To manufacture a building structure, for example, a building wall, fibrobeton formwork plates 1 are installed in two rows opposite each other at a distance equal to the structure thickness, they are joined together by fastening elements 4, and the concrete mix is placed into the space between the formwork plates 1 Or another material that fills the cell-bulk fibrous frame of the additional anchoring layer 2 forms a fibrous concrete layer at the inner surface of each formwork plate that is more durable than concrete.

The use of fixed fiber-reinforced concrete formwork with an additional anchoring layer makes it possible to increase the strength of the building structure by 1.36 times. As a result, it is possible to reduce the thickness of the fiber concrete formwork plate by 1.53 times.
