i 82284 MOUNTING SYSTEM

The invention relates to a fastening system for mating molds or building elements to be connected to molds forming the outer surface of a structure. In the fastening-5 system, the casting molds or the casting mold and the building element are connected to each other to provide a uniform mold structure. Such fastening systems are used, for example, in mold systems forming a steel-concrete composite structure. Such a mold system 10 is known, for example, from FI patent publication 74100. It describes a self-supporting building frame mold system consisting of molds acting as metal housings, mold support structures and reinforcements, the molds being of different cross-sections, preferably open-facing and reinforcing. - and reinforcement structures, so that the system can be assembled so that the entire building frame is cast in one step.

It is advantageous to use such formwork systems when it is desired to avoid the cumbersome and expensive transport and erection steps of the finished columns and beams as well as the wall elements.

Such mold systems are known in the context of column castings. Wall structure casting systems have not been used due to the lack of a suitable method of joining wall structures to the system. The wall structures to be connected to the pillars have thus been mainly prefabricated elements, so the advantages provided by the system have only been partially utilized. However, the use of such mold systems in wall structures is as justified as in the case of vertical structures.

The fastening system according to the invention is characterized in that the second mold or building element to be connected to the mold comprises a tongue 2 82284 attached to its outer surface, which passes through an opening in the mold and is attached to the mold.

When using the fastening system according to the invention, the light wall structures 5 can also be manufactured by casting simultaneously with the casting of the building frame, or the finished elements can be fastened to the casting simply and easily. In this case, all mold installations can be carried out quickly and economically with light cranes.

In the following, the invention will be described in light of some preferred fastening systems with reference to the accompanying drawings, in which

Figure 1 shows the attachment of a wall element to a mold 15 forming a building frame. Figure 2 shows a horizontal section of the previous one.

Figure 3 shows the attachment of a wall element to a mold forming the building frame

Figure 4 shows a horizontal section of the previous one.

Figure 1 illustrates the attachment of a light wall element 3 to a casting mold forming a building frame, which in this case is a Pillar Mold 2. The fastening member 10 comprises a vertical tongue 11 threaded into the opening 7 formed in the mold 5 so that the tongue remains inside the casting mass 25 As the concrete binds and forms a uniform casting component, the tongue adheres firmly to the casting component. Further openings 13 are formed in the tongue 11 for the casting component to ensure the attachment of the tongue.

The fastening member 10 also comprises means 14 for fastening the wall element 3 30 to the fastening member 10. In this case, the fastening member 14 is a U-shaped strip-like horizontal body 3 82284, on the flanges of which the upper edge of the wall element rests. The lower edge of the wall element is arranged to be supported by a member 15, which is an L-shaped horizontal rail fixed to the mold 2.

5 As shown in Fig. 2, the vertical opening 7 formed in the casting mold 2 is so narrow that the tongue 11 can barely pierce it. When the tongue is threaded through the opening 7, the fastening member is pressed downwards, whereby the U-shaped member 14 engages at the upper edge of the element 3 to be joined and presses the element 10 against the mold. At the same time, the rear edge of the tongue 11 is pressed down behind the opening 7 and the tongue rests against the wall 5 of the mold. For the wall 5, a narrow groove 12 is formed between the tongue 11 and the member 14. The opening 7 is covered in some suitable way before the casting is carried out.

Figures 3 and 4 show the fastening of a casting mold forming a building frame, which is also a Pillar mold 2, and a connectable casting mold, which is a wall mold 1, in the case where the castings of the elements are performed separately for each mold to be joined. In this case, the pillar remains behind the wall 20, the facade forming a uniform surface.

In the case according to Figures 3 and 4, the tongue 11 is attached to the wall 5 of the casting mold 2 or the tongue 11 is preferably integral with the wall 5. The tongue 11 is in this case wedge-shaped upwards. The opening 6 formed for the tongue 25 11 is correspondingly arranged in a casting mold 1 to be connected. The mold 1 rests at the upper edge of the opening 6 at the wall 4 against the tongue 11. Due to the wedge-shaped shape of the tongue, the mold 1 to be joined is pressed tightly against the wall 5 of the mold 2 30 forming the building frame.

In the case of Figures 3 and 4, two tongues 11, 11 'and two openings 6, 6' are formed one below the other for connecting the wall mold. The number of tabs and openings depends on the size and weight of the element to be joined.

The top edge of both molds is open or openings are formed in the top edge for performing the casting. The casting mass 8 forms, for example, a steel-concrete composite structure with the casting mold acting as a housing, the tongues 11, 11 'and the reinforcement of the building part (not shown in the figure) 5.

The invention is not limited to the embodiments described above, but can be modified within the scope of the following claims. For example, the shape of the tongue is not limited in any way to the tongues 10 described in the previous embodiments, and the member used to attach the wall element may also have another shape.
