Description

Object of the Invention

As indicated by the title, the invention relates to a fastening clamp for fastening frames or casings to brick walls to obtain the perfect attachment of the frame to the bricks without damaging the frame or breaking the brick, directly installing same as the partition is being raised.
In a first version, the specific frame object of the invention has dovetail-shaped grooving and does not need to be made of a soft material such as wood, since the grooving allows the assembly of the fastening clamp of the invention either by clipping or embedding, being able to freely regulate the height at the time of installation so as to be located between two courses of bricks.
Conventional wooden frames are used in a second version and the assembly element of the clamp of the invention is nailed by pressure without any impact, without needing added fixing elements such as screws, brads or adhesives. They are installed in the moment of construction, when the partition is raised, in each course of bricks of such that the clamp of the invention is located in or between the joint or heading joint between two rows of bricks.
In both cases, the clamp is installed on the installed and plumbed frame, without needing to exert any forces thereon that may shift it, damage the setting of the bricks of the lower courses or weaken the already formed unions.

Background of the Invention

The union between partitions and frames is currently done by means of nails, anchor bars, fastening irons or anchors for partitioning. In the case of nailing with brads and of the anchor bars fixed to the frame also with brads, the members are previously installed in the frame so that they do not coincide with the joints or heading joints, therefore having to break the bricks. Breaking bricks creates rubble, causes such bricks to lose both acoustic and mechanical strength, as well as making it difficult to perform plasterwork since the parts received with plaster or mortar create an area with high moisture content. The latest anchoring device for partitions described in Utility Model ES 1 063 237 U belonging to SIPOR-PLAC, S.L., which defines three basic members made from thin malleable sheet metal with multiple functions, is characterized by the need for an external fixing member, such as brads or screws, for their fixing to the frames, but is fundamentally thought, and thus explained in the explanation and examples provided, for the union between partition parts when the partition is raised with large plates in which mortar has a less integrating function than small bricks.

Inventive Step

The advantageous purpose of the invention as can be summarized from the explanation relating to the object thereof in the first paragraphs of this specification is that which provides an essential element of fastening frames to brick walls, with considerable advantages for the builder, the installer and applicr of wall covering because it is a member with important mechanical and functional features, it is self-sufficient and does not require other fixing devices such as brads or screws, which is installed as the partition is being raised, being perfectly placed in the joint without needing to break the brick and having additional anchoring means to improve the attachment to the partition.

Description of the Invention

Accordingly, the invention is essentially based on a set of clamps, preferably metal clamps, designed both for being assembled in a specific frame and for being fixed in a common frame, the latter being able to be made of a soft material and the former of any type of material, including hard material In the first case, the clamp is simply and easily assembled without the need of mechanical aid either by guiding it in the specific frame, having a suitable section, or by adapting it laterally by means of a slight coupling movement, whereas the second case requires a tightening tool for its assembly provided by the invention, or by means of another common tool, such as a grip or vise.
The clamps according to the invention have the mentioned adaptation configurations and means as well as the features for being placed and located correctly on the plane or edges of the bricks as the wall, partition or the like is raised, such that the part joined to the bricks is firmly held by the mortar joint or heading joint serving as a union to the brick bond. Therefore when the operator finishes the course in which the clamp is to be installed, he or she locates it, applies the mortar mass and places the brick of the following course such that in the first case, the brick is housed in the specific frame in the space set aside for such purpose, and in the second case the brick is housed against the common frame.
We will now carry out a broader idea of the features of the invention by referring to the sheets of the drawings accompanying this specification where the preferred details of the invention are shown in a schematic manner and only as an example.
