Description

A BUILDING CONSTRUCTION AND A METHOD FOR JOINING ELEMENTS
OF BUILDING CONSTRUCTIONS
DESCRIPTION
TECHNICAL FIELD
The present disclosure relates to a building structure and a method for joining building structures, relating to joining of prefabricated constructional elements, in particular prefabricated fragments of walls, ceilings and roofs.
BACKGROUND
There are known prior art systems for constructing buildings that utilize prefabricated components such as complete walls. Prefabricated walls or their fragments are joined by reinforcement elements and the connection points are filled with wet concrete mass. This technique is time consuming, requires relatively large amounts of concrete mass and is not suitable for use at low temperatures, especially in winter.
There is also known a method for joining by screws reinforced prefabricated walls that have an outer steel frame. However, such a solution leads to a relatively large weight of the whole prefabricate and low flexibility during the assembly, due to predetermined shapes of the reinforcements and locations of the joints between the walls.
There is a need to provide a system for joining prefabricated constructional elements, which would allow fast assembly of structures with a predetermined dimensional precision and which could be utilized in a wide range of atmospheric conditions.
SUMMARY
The object of the invention is a building structure comprising a first constructional element connected with a second constructional element, wherein the constructional elements are connected with each other by means of at least one positive connection tightened by a screw connection.
Preferably, the first constructional element comprises a threaded sleeve having an opened end located in the first shaped element of the positive connection, and the second constructional element comprises a sleeve coaxial to the threaded sleeve, the sleeve having a first opened end located in the second shaped element of the positive connection and a second opened end connected with an opening in a surface of the second constructional element, wherein the constructional elements are joined with the screw, wherein a first threaded end of the screw is screwed into the threaded sleeve, and a second end of the screw is located in the opening and has a tightening nut screwed onto it.
Preferably, the opening is located beyond the positive connection.
Preferably, the shaped elements of both slab constructional elements are located in front surfaces of the slab constructional elements.
Preferably, a shaped element of the first slab constructional element is located in the frontal surface of this constructional element, and a shaped element of the second slab constructional element is located in the side surface of this constructional element.
Preferably, at least one of the constructional elements, is a fragment of a wall.
Preferably, at least one of the constructional elements is a fragment of a ceiling slab.
Preferably, the positive connection is a tongue and groove type joint. Preferably, the positive connection is a splined joint.
Preferably, the positive connection is a lap joint.
Preferably, the positive connection has a trapezoid cross-section.
Preferably, the positive connection has a rectangular cross-section.
Preferably, the positive connection has a triangular cross-section.
Preferably, the positive connection has an arcuate cross-section. Another object of the invention is a method for joining elements of building structures, characterized by performing the following steps: moving a first constructional element towards a second constructional element while matching a first shaped element in the first constructional element to a shaped element in the second constructional element; and subsequently tightening the positive connection by means of a screw connection.

DETAILED DESCRIPTION
The following embodiments are described for use in joining wall fragments. However, the presented system may be also utilized for other prefabricated constructional elements, such as for example ceilings, or their combinations.
Fig. 1A shows a cross-section of a longitudinal joint of constructional elements, for example walls. The first constructional element 1 is joined with the second constructional element 2 by a so-called scarf joint or a tongue and groove joint, that is a positive connection, which prevents a mutual movement of the constructional elements 1 , 2 in a transversal direction with respect to their main plane. The joint shown in Figs. 1A-1 B is a butt joint, it means that shaped elements 1 1 , 12 are formed in frontal surfaces of the constructional elements. The constructional elements 1 , 2 are joined together by a screw 4. In the first element 1 there is a threaded sleeve 3. The threaded sleeve 3 is placed inside the element during its production. The threaded sleeve 3 is placed in the material of the constructional element in a way that its open end is located within the shaped element 1 1 . In the second element 2 there is a sleeve 6 of the screw, which together with the threaded sleeve 3 forms a screw connection between the walls. The screw connection is located within the positive connection. For example, the threaded sleeve 3 of the screw is located in the groove of the joint (the first shaped element 1 1 ), and the sleeve 6 of the screw is located in the tongue of the joint (the second shaped element 12). Therefore the positive connection is directly fixed. It allows to save space by minimization of thickness of the constructional elements 1 , 2 and their effective joining so that the space between them is as small as possible.
On the surfaces of the positive connection between the constructional elements 1 , 2, there is a seal material 5. It fills the space between the constructional elements 1 , 2 providing the sealing of the joint against air, humidity and other factors. For example the material may be on the basis of resins, glues used in construction or only a cement mortar.
In the second element 2, in its side surface, there is an opening 9 which enables placing a nut 8 together with a washer 7 on the end of the screw 4 and screwing it in by for example a wrench. The opening 9 may be filled with a prefabricated block or a filling material at the further stage of finishing the wall. The prefabricated constructional elements 1 , 2 may comprise a reinforcement 10. Fig. 1 B shows the joint of Fig. 1 A in a perspective view.
The prefabricated constructional elements 1 , 2 may be made of concrete or aerated concrete, although the preferred material is expended clay concrete. The expanded clay is resistant to molds, fungi, pests. It is also ecologically clean, sound-absorbing, chemically inert, fireproof, alkali-resistant, acid- resistant and odorless.
Within the positive connection, two or three nut and screw connections, evenly distributed along the height of the joined walls, are enough to provide an effective connection. The constructional elements 1 , 2 may have the side surfaces coated with different kinds of coating layers (for example a plaster, a paint, a lacquer) or warmth-providing insulation layers (for example Styrofoam).
The constructional elements 1 , 2 have a thickness dependent on the material they are made of and on the desired strength and insulation parameters, for example they may have the thickness from 5cm to 30cm. The length and the width of the constructional elements 1 , 2 depend on the shape of the construction, which they are part of. The constructional elements may have a form of flat or bended slabs.
The openings 9 have dimensions suitable for placing therein the nut 8 and a tool for screwing the nut 8 onto the screw 4 inside them or possibly suitable for inserting the screw 4 into the sleeve 6 from the opening side. For example, the openings 9 may have a rectangular shape with the height (measured perpendicularly to the axis of the screw 4) from 5cm to 20cm and the length (measured in parallel to the axis of the screw 4) from 5cm to 50cm. The depth of the openings depends on the location of the sleeve 3, 6 and preferably is greater than the half of the thickness of the constructional element.
The positive connection between the constructional elements may have shapes other than these shown in the first embodiment. Further examples of various shapes are described below with reference to Figs. 2A-2E.
Fig. 2A shows a double, trapezoid-shaped positive connection 1 1A-12A, with two parallel screw connections. Fig. 2B shows a singular trapezoid-shaped positive connection 1 1 B-12B (as in Fig. 1A). Fig. 2C shows a rectangular positive connection 1 1 C-12C. Fig. 2D shows a triangular positive connection 1 1 D-12D and Fig. 2E shows a positive connection of an arcuate, semi-circular cross-section 1 1 E-12E.
The constructional elements, for example walls, are joined according to the following method: the screw 4 is screwed into the threaded sleeve 3 of the first constructional element 1. Next, the second constructional element 2 is moved towards the first constructional element 1 , so that the screw 4 passes through the sleeve 6 of the second wall 2 and its end fits into the opening 9. Through the opening 9 of the second wall 2, the nut 8 is put on the screw 4 and is screwed in for example by means of a torque wrench. The size of the opening 9 is configured so that it is possible to screw in the nut. After tightening the nut, the opening 9 may be closed, for example by means of a block corresponding to its dimensions so that it is possible to further finish the wall e.g. putting a plaster or an warmth-providing insulation etc.
The screws 4, used for joining the constructional elements 1 , 2, are preferably standard screws used in building construction. In this embodiment, a double ended screw is used. It is also possible to assemble the elements in a manner wherein first the joined elements are moved towards each other and next the screw 4 is screwed into the threaded sleeve 3, by inserting it through the opening 9 and consecutively through the sleeve 6, which are situated inside the element 2, and next the nut is screwed onto the screw 4 which partially extends inside the opening 9. The opening 9 must then be adequately longer so that it is possible to introduce the screw 4 through the opening 9 into the sleeves 6 and 3.
It is possible to use different shapes of cross-sections of the positive connection so that it has a function analogous to the presented one. The system for joining the walls according to the invention may have more parallel positive connections connected by means of side by side screw connections, as shown in Fig. 2A. Without departing from the essence of the invention, it is also possible to mount constructional elements under certain angle between each other, preserving the idea of the present invention.
The following figures show different types of embodiments of the joint according to the invention.
Figs. 3A-3B show the first embodiment of the corner joint, similar to the longitudinal joint shown in Figs. 1A-1 B, wherein a first shaped element 31 is located in the side surface of the first constructional element, and a second shaped element 32 is located in the frontal surface of the second constructional element 2.
Figs. 4A-4B show the second example of the corner joint, in which the joint of shaped elements 41 , 42 is the lap joint. It is particularly preferable when the first constructional element 1 is a fragment of the wall and the second constructional element 2 is a fragment of the ceiling slab.
Figs. 5A and 5B show the first example of a perpendicular joint, in which a first shaped element 51 is located in the side surface of the first constructional element 1 and a second shaped element 52 is located in the front surface of the second constructional element 2 having the opening 9 in its side surface.
Figs. 6A and 6B show the second example of the perpendicular joint, in which a first shaped element 51 is located in the front surface of the first constructional element 1 and a second shaped element 52 is located in the side surface of the second constructional element 2 having the opening 9 in its second side surface.
