Description
- The present invention is related to a structural horizontal building panel or floor panel. More specifically, it relates to a floor panel with an embedded block that permits connection of the floor panel to wall panels above and below the floor.
- Panels that are prepared and fabricated off-site embody a major improvement in the construction field for implementing a high level of standardization for certain building procedures, decreasing costs and facilitating a better quality control of the panels.
- The fabrication and the mounting process of floor panels need a high level of accuracy in order to be assembled properly on-site. The assembly must maintain its integrity as the floor panel may be subjected, over time, to wall panel vibrations or movements that can potentially impair a building's structure.
- This background is not intended, nor should be construed, to constitute prior art against the present invention.
- The present invention is related to a floor panel that has features for connecting it to wall panels. The floor panel has floor connector blocks placed at each corner, for example, integrated in the floor panel. The floor connector blocks also act as anchoring sites where hooks can be mounted in order to lift the floor panel. The floor connector block has projecting anchor pins that provide a mechanical anchor in the cementitious material of the floor panel. The structure of the floor connector block facilitates the fixation of the wall panels to the floor panel using a tapped-head bolt, which has a female threaded head and acts as a double fixation component. Two plates for stabilizing the position of the tapped-head bolt are located inside the floor connector block.

- It is worth noting that the actual rectangular shape, the proportions and the dimensions shown are simply an embodiment of the present invention and can be subject to modification. For example, in some embodiments, the connector block body may have a rectangular cross-section or may be cylindrical. Additional play may be incorporated into the connector assembly to allow for a greater range of adjustment to the final positions of the connected wall and floor panels.
- Other methods of fixing the supporting plates to the connector block body may be used in other embodiments. For example, the plates may be fastened in place by shrink fitting the body to them. In this case, the inner walls may not need to have recessed shoulders, and the wall of the floor connector block may have the same thickness throughout. In some embodiments, retaining pins or screws may be used to fasten the supporting plates (e.g. 58, 66) to the body of the connector block. The pins can be inserted and welded into holes located in the body of the floor connector blocks. Screws or bolts may be used in threaded holes in place of retaining pins.
- In some embodiments, the threads of the tapped-head bolt may be located differently.
- In some other embodiment, materials other than steel may be used, such as glass-fibre reinforced plastic.
- The connector blocks may be positioned or oriented differently than shown is the exemplary embodiments. The anchor pins may be aligned with respect to each other at angles other than 90°, for example at any non-parallel angle including 180°. Anchor pins projecting from the same side of the connector block may not be parallel to each other. The number of anchor pins projecting from the interior faces of the connector block may be other than two.
- The bottom plate may be recessed in the connector block rather than flush with the bottom of it. In this case, the bottom section with thinned
walls 116 extends upwards more than shown in the figures. Nevertheless, the bottom plate is still located at the open bottom end of theconnector body 12. - In some embodiments, the block assembly may be located in the horizontal building panel away from the corner. For example, it may be located part way along a side edge of the panel, or in the central area of the panel.
- In general, unless otherwise indicated, singular elements may be in the plural and vice versa with no loss of generality.
- Throughout the description, specific details have been set forth in order to provide a more thorough understanding of the invention. However, the invention may be practiced without these particulars. In other instances, well known elements have not been shown or described in detail and repetitions of steps and features have been omitted to avoid unnecessarily obscuring the invention.
