Definitions
- the present invention relates to a device for assembling prefabricated reinforced concrete structures.
- precast reinforced concrete structures are fast, efficient and inexpensive.
- a decisive part of this method of construction is the assembly on site of the various elements constituting the supporting structure.
- the assembly of structures made up of beams, slabs or shells is based on the principle shown diagrammatically in FIG. 2 and characterized as follows: a concrete element (B) stressed by a load (G) -is supported on a concrete support element (A) via a contact piece (P).
- This contact piece is compressed by means of the fictitious compression rod (O) (according to the analogy of the Morsch lattice).
- This assembly is characterized by two sheared zones (U) and (V) which must transmit the load over half the thickness of the concrete elements resulting in two zones of weakness forcing the concrete elements to thicken. This thickening results in an increase in self-weight and an increase in cost.
- FIG. 1 shows an embodiment of the device according to the invention
- FIG. 2 shows an existing system for assembling reinforced concrete elements
- FIG. 3 shows an example of application of the device to a slab
- FIG. 4 shows an example of application of the device to a console beam
- FIG. 5 shows an example of application of the device to a beam.
- FIG. 1 An embodiment of the device according to the invention is illustrated in FIG. 1 for the assembly of two prefabricated reinforced concrete elements each characterized by an upper face, a lower face and an end face.
- the first concrete element is called the support element (A); its lower face rests on a support (H) and it has an inclined end face such that its lower face is set back with respect to its upper face (a cantilever cut).
- the second element called the charged element (B) is stressed by a load (G); it has an end face inclined inversely with respect to the first element such that its upper face is set back with respect to its lower face (a front nozzle cut at an angle).
- the end faces of the support element and of the loaded element are inclined and their surfaces can be flat, composed of several facets or even curves.
- the concrete elements are fixed by applying their end faces against each other using a fixing piece (C) made of metal, composite material or the like.
- This fastening piece is composed of a rod terminated at these two ends by anchoring plates (E) and (F) and has a fastening system (D) of bolting, key or other type.
- This fixing piece allows the loaded element to be suspended from the support element.
- This device allows the load (G) to be transmitted by a fictitious compression link (0) resting on the anchor plate (F) (located in the lower part of the loaded element), then taken up by traction in the rod of the part (C) and retransmitted by the anchor plate ( E) (located in the upper part of the support element) in the form of a compression rod (N) in the direction of the support (H).
- the device shown in FIG. 1 also allows the flexion to be transmitted from one element to the other by decoupling traction and compression.
- the traction stressing the reinforcements (L) and (M) close to their upper faces is transmitted by a coupler (K) from one concrete element to another.
- the compression located in the lower part of the concrete elements is transmitted by a contact zone (J).
- the two concrete elements (A) and (B) as well as the part (C) are characterized by an injection network allowing the circulation of an injection grout.
- FIG. 3 An embodiment of the device according to the invention is illustrated in FIG. 3 for a slab (B) suspended on a column surmounted by a mushroom (A) whose inclined end face is cut in steps on one side and flat on the other.
- These elements are assembled by one or two fixing pieces (C) per section which are fitted at each end with a fastening system. The bending is transmitted from one element to the other via the coupler (K) and the contact zone (J).
- FIG. -4 Another embodiment of the device according to the invention is illustrated in FIG. -4 for a beam (B) suspended on a console (A) by a fixing part (C).
- This assembly transmits only the shearing force thus reproducing a ball joint.
- This ball joint as well as the installation of an insulating material (T) between the end faces of the elements make it possible to limit the transmission from one element to the other of heat (X) or / and vibration of the charges (G ).
- FIG. 5 Another embodiment of the device according to the invention is illustrated in FIG. 5 for a beam (B) suspended from two support elements (A) by means of fixing parts (C); to the left of the beam, the inclined end face is curved and the fixing piece is also inclined.
- the compression due to bending is transmitted by the contact zones (J) without interrupting the arc effect symbolized by the curve (W).
- the traction due to bending is transmitted to the left by the coupler (K) and to the right by means of a support element characterized by a hook (Q) fitting into a jaw (R) arranged on the element loaded so as to transmit the tensile force due to the bending by compression of a contact zone (S).
- the device for assembling precast concrete elements by suspension according to the invention offers the following advantages compared to the standard system presented in FIG. 2.
- the thickness of the concrete elements may be reduced because the zones of weakness due to shearing over half the thickness of the elements no longer exist.
- the transmission of vibrations and / or heat from one element to another can be limited to that transmitted by the fixing part.
- Construction is simplified since it is done from below (without having to pass the loaded element over the support element using a crane). This implementation can be carried out using jacks resting on the support element which hoist the loaded element (disposed below its final position) by means of cables.
