Description

PLASTERING METHOD AND SYSTEM

FIELD OF THE INVENTION

The present invention relates to plastering methods. More particularly, the present invention relates to plastering method and system in which the plaster is disengaged of the wall.

BACKGROUND OF THE INVENTION

An enormous area of the populated world is situated on sea and ocean shores and the buildings are built in the vicinity of the shore. There are ancient cities on sea shores in which the building blocks and stones for the buildings were made of rocks from the shore. In both situations a problem arises from the salty water. In the ancient buildings, the stones are made of rocks from the shore. The rocks are porous since they are mostly conglomerates of shells and other particles that were merged due to pressure from upper layers. Since the stoned are originated from the ocean, they are soaked with salt water and eventually due to dehydration, they are saturated with salt. Over the years and although the stones are secreting the salt, there is a balance of salt secretion due to new salt that is raised to the walls of the buildings and to the stones from the ocean by capillary force as well as sprayed on the walls by wave blasts to the shore and rocks. The problem of salty water blasts and capillary absorption of salt in walls of buildings exist also in the new buildings. This causes a complicated problem when the buildings have to be plastered.

One of the problems that arise when plastering a wall of a building in an area that is in a vicinity of a salty sea or lake is that after a certain time, the salt that is secreted from the stones of the wall is starting to accumulate between the wall and the plaster and to form cracks and damage the wall or the plaster. The practice nowadays is to repair the plaster again and again, hoping the weak link in the chain will be the plaster that will crack rather than the wall itself.

Since there is no solution to this problem, houses in areas that are in the vicinity to sea or oceans have to be plastered relatively frequently using expensive methods. This is relevant especially in cases of relatively old houses and houses for preservation. It is a ling felt need to provide a solution to this problem that is easy to implement, long lasting, and cost effective.

The present invention provides new and unique system and method for disengaging plaster of a wall. This system is especially designed for plastering buildings in areas that are in the vicinity of seas or oceans that are salty. The salt from the sea reaches the walls of the building through the ground or through waves and causes sever damages to the plaster or to the walls themselves. The practice nowadays is to plaster the walls in these areas often and to repair the plaster rather frequently.

According to one aspect of the present invention, it is provided a plastering system that is attached to the wall while the plaster is spread on the plastering system rather than on the wall. The plastering system forms a space into which the salt crystals that are secreted of the wall can be accumulated without inflicting any damage to the plaster or the wall. The plastering system generally comprises an intermediating member having a surface with curved profile that is attached to the wall. The curves form spaces into which the salt can be accumulated.

Reference is now made to Figure 1 illustrating a cross sectional view of plastering system in accordance with a preferred embodiment of the present invention. Plastering system comprises a member 10, which is an intermediate member, adapted to act as a disengaging means having two sides; a frontal side 12 that will eventually face the plaster and a back side 14 facing the wall (the wall is not shown in the figure). Back side 14 is intended to be connected to the wall and therefore it has a curved profile. The curved profile maintains most of member 10 in a predetermined distance from the wall. Only the protrusions come into contact with the wall so that most of the wall is disengaged from member 10. It should be understood that the object of the system of the present invention is to provide a way of plastering the walls without spreading the plaster directly onto the wall. The plaster is spread on the plastering system that provides space for accumulation of salt crystals that are being secreted of the walls. The intermediate member can be made of relatively soft sponge-like material such as polystyrene or Styrofoam, paper, or any other matrix. The material is chosen according to several characteristics such as low weight, ability to receive the plaster layer, prolonged lifetime, environmental friendly, fire resistant, adapted to be carved, isolation properties, strain resistance, and other characteristics that are chosen according to the specific needs of a specific wall.

It should be emphasized here that an inherent advantage is imparted to the wall and the building using the plastering system due to the use of a foamed member. The member renders the building and the walls with additional isolation that isolated the walls from disturbances such as cold, heat, noise, etc.

Member 10 is provided with nails 16 adapted to be anchored to the wall. Nail flange 17 is provided to nails 16 so as to establish a firm connection between the member and the wall. It should be mentioned that any other attaching means between the wall and the disengaged plastering layers can be provided. The attaching means should be such that corresponds the requirements of a specific wall that is being plastered.

Optionally, an intermediate layer 18 is attached to member 10 while intermediate layer 18 can be provided also with a supporting element such as a wired mesh, fiberglass mesh, or similar reinforcement means.

A plaster layer 20 is provided on intermediate layer 18. Plaster layer 20 is spread in a similar manner as regular plaster on a surface. Intermediate layer 18, if needed, will be of a material that fits the specific type of plaster used.

Reference is now made to Figure 2 illustrating an exploded view of plastering system in accordance with another preferred embodiment of the present invention. The plastering system is provided with a member 100 that keeps the plaster layer off the wall (the wall as well as the plaster is not shown in Figure 2). Nails 102 and flanges 104 are similar to the ones shown in the previous embodiment (16, 17). A reinforcement network 106 made of a stiff material is provided as a layer that supports the plaster that will be spread onto it.

As shown herein before, member 100 is provided with a curved surface 108 so as to provide minimal contact between the wall and the member as possible and provide also a space for salt crystals to be accumulated. Curved surface 108 is optionally provided with wiring tunnels 110 that are provided in order to allow wiring duct 112 to be installed within for all purposes of wiring such as electricity, water, or communication. This fact illustrates another possible advantage of the plastering system of the present invention. The ability to form wiring tunnels within the member of the plastering system allows the user to avoid excavation of the walls themselves while inflicting damage to the walls; this is especially applied in relatively old houses or ancient buildings.

Reference is now made to Figure 3 illustrating an isometric view of the plastering system shown in Figure 2, assembled and provided with wiring. Wiring duct 112 is provided within the tunnel so that wiring 114 for any purpose can be transferred through the tunnels. Wiring tunnels can be carved in the plastering system according to the need even if they arise before plastering. If is possible to disengage the system of the wall, curve the wiring tunnels if needed and recover the system again to the wall. It should be emphasized again that the use of this system eliminates the need to curve in the walls for the different wiring systems, which is especially crucial in case of old buildings that in preservation process.

Reference is now made to Figure 4 illustrating the members that are connected to the wall with wiring means. The formation of a wiring tunnel 202 in member 200 prior to incorporating wiring is shown in accordance with a preferred embodiment of the present invention. A wall 204 is shown to have minimum contact points 206 between the wall and the member leaving an open space 205 adapted to receive the salts that crystallizes on the surface of wall 204, as mentioned herein before.

Reference is now made to Figure 6 illustrating an exploded view of a plastering system in accordance with yet another preferred embodiment of the present invention. Basically, similar components comprise the embodiment shown in Figure 6; however, a spacer 602 is provided in order to provide vacancies that will allow salt accumulation without damaging the plaster.

The disengaged plaster is provided onto member 600 that is adapted to maintain the plaster layer. A mesh 602, which is adapted to keep member 600 off the wall (the wall is not shown in Figure 6), is provided and is adjacent to member 600. Nails 102 and flanges 104 are similar to the ones shown in the previous embodiments. A reinforcement network 106 is provided as a layer that supports the plaster that will be spread on it. The role of the reinforcement network is to enforce the plastering system from stress forces and to prevent the plastering system from cracking.

Differently from member 100 (shown in Figure 2, as an example), member 600 is provided with a smooth surface and therefore is contiguous to mesh 602 that provide a space in which salt can be accumulated. The surface of member 600 that faces the wall is optionally provided with wiring tunnels 110 that are provided in order to allow wiring duct 112 to be installed within, as shown herein before.

According to another aspect of the present invention, the plastering system is provided with an intermediating member that can be a meshed network as an example, onto which a breathing layer is provided wherein the breathing layer is adapted to receive the plaster. Between the two layers, a geotechnical fabric is to be provided in order to separate the two layers.

Reference is now made to Figures 6 a and b illustrating cross sectional and isometric views of a plastering system in accordance with yet another preferred embodiment of the present invention. Figure 6b is a isometric view that is partially exposed in order to better understand the organization of the layers. In this plastering system, a mesh layer 700 is designed to be attached to the wall so as to provide spaces in which the secreted salt can be accumulated. Then, a geotechnical fabric 702 is provided to prevent the plaster from reaching into the spaces of mesh 700. A honeycomb meshed layer 704 is then provided adjacent to the fabric. The plaster is spread onto this layer and is inserted within the spaces of the honeycomb layer. Honeycomb layer 704 can be made of a group of materials such as polypropylene, polycarbonate, etc. A smooth layer of plaster can be achieved on the honeycomb layer.

The plastering system is nailed to the wall using nails 104 as shown herein before.

It should be noted that the plastering system of the present invention is easy to maintain since it comprises a plurality of pieces and preferably rectangular pieces in order to facilitate its arrangement on the wall. The pieces are reversibly connected to the wall. If there is any damage to the plaster, only the damaged portion can be repaired or even replaced.

It should be mentioned that the plaster can be any type of conventional or non conventional plaster of cement base, polymer cement, or any other. The reinforcing means can be made of a stiff material such as fiberglass, metal, or any other suitable material. It should be noted that the present invention can solve problems that may arise from other sediments that may accumulate on the walls. Any materials other then salt that are present in the soil near the wall and may crystallize on the wall can cause the same effect as salt and therefore, the plastering system of the present invention can be used for any case in which the plaster to be spread in a disengaged manner from the wall and not directly spread.

As shown herein before, the intermediate member that can comprise a meshed network, a mesh, or a foamed member is provided with spaces that allow crystals of salt to be accumulated within. It accordance with yet another aspect of the present invention, a new and unique method of disengaging the plaster of the wall is provided. The, method is based on the plastering systems that were disclosed herein before. The method of disengaging the plaster of the wall comprises attaching plastering systems adjacent to each other so as to cover a portion of the wall or the whole wall using nails as shown herein as an example. Then, the plaster is spread onto the plastering systems. It should be mentioned that there is no significant to the proportions of the different layers as regard to their thickness and every layer can be designed to be in different thickness and in accordance with the specific requirements of the wall. It should be clear that the description of the embodiments and attached

Figures set forth in this specification serves only for a better understanding of the invention, without limiting its scope as covered by the following Claims.

It should also be clear that a person skilled in the art, after reading the present specification can make adjustments or amendments to the attached Figures and above described embodiments that would still be covered by the following Claims.
