Abstract

A method of constructing seismic shock absorbing structure which transfers horizontal and vertical forces from the floor to allow buildings to withstand earthquake shocks. In a first embodiment, foundation column is structurally designed and casted in the form of a fin shape below plinth level. In another embodiment, strength of the construction frame is enhanced by structurally designing, casting and slotting in at least one of rhombus shaped beams, diagonal cross beams, corner beams, plus shaped beams, rectangle shaped beams, semi-quarter circular beams in horizontal, vertical and inclined directions at the plinth level, below and above the plinth level. In another embodiment, wall is interlocked with at least one of Reinforced Cement Concrete (RCC), cement composites, steel, iron, metal, concrete, polystyrene, polyurethane, wood, plastic, fired bricks, cardboard and clay blocks. In another embodiment, interlocked wall is reinforced with GI (Galvanized) welded mesh, fiberglass mesh and wire mesh.

STATEMENT UNDER ARTICLE 19 (1)

T itle: A M ethod of C onstructing E arthquake R esistant Structure with reinforced foundation and wall structure

In reference to the Item V( Reasoned statement) of the written opinion of International Searching Authority the subject matter of originally claim 1- 7, 9 and 10 were rejected as being not inventive and not novel over document D1 , D2 and D3. Claim 8 was rejected being not inventive over document D1, D2 and D3

It is believed that the amended new claims 1 -7 now clearly distinguish from the prior art document D1, D2 and D3, as it will become apparent from foil owing remarks.

1. Rendering to new claim(s) 1 to 7 amended on basis of claims 1 -10 as originally filed, the present invention, A M ethod of C onstructing E arthquake R esistant Structure with reinforced foundation and wall structure comprises use of interconnecting beam in the frame of structure, foundation column with Fin shaped propping, interlocked reinforced wall structure and the interlocked wall structure reinforced with GI (Galvanized) welded mesh or fiberglass mesh or wire mesh to strengthen the new construction as well as existing structures against the seismic shocks.

Document DI is a PR E FA BRICAT E D WA L L PA NE L which includes molds for casting reinforced concrete (RC) elements. The differences between document D1 and present i nventi on are as f o! I ows:

1. The invention disclosed in D1 is applicable and limited to Prefabricated Wall Panels only whereas the present invention is applicable to every type of 38

constructions including new constructions, existing constructions, prefabricated structures etc,

2. The prefabricated wall panels are placed separately around vertical rebars whereas in the present invention the reinforced wall structure is first reinforced with bottom beam-slab rebars and then constructed with the help of hook shaped locking mechanism which will be then reinforced with columns and upper beam- slab. The Reinforced Masonry wall is firmly attached to the Structure Frame as a single unit In the conventional construction method, no interlocking is provided between the frame structure and the wall masonry, thereby leading to an unbalanced brick walls ultimately collapsing on the slab and damaging the whole structure.

3. The present invention discloses that the columns below the plinth are provided with the additional props in the forms of Fins. This Fin shape foundation columns resist the horizontal and vertical movements of the structure during earthquake in a better manner than the existi ng structures.

4. A I so the present i nventi on di scl oses that the vari ous i nterl ocked shaped beams are interconnected in the frame of the structure ABCD [Fig.2 and Fig. 5-54] in new construction as well as in existing structures in horizontal, vertical and inclined I evel s to i ncrease the strength of the structure to a greater extent

Document D2 (Aseismic Reinforcing Structure) provides an aseismic reinforcing structure capable of improving the aseismic performance of an existing column without causing a crack in the existing column by a reinforcing column for the existing column and existing beams. The differences between Document D2 and present invention are as follows:

1. The invention disclosed in D2 is provides aseismic performance to existing column (existing structure) only whereas the present invention is applicable to 39

every type of constructions including new construction, existing construction, prefabricated structure etc,

2. As disclosed in D2, A reinforcing column (8) is erected at a position outside an existing column (2) located on the building outer wall side of an existing building so as to face the existing column with a space (7) there between. The lower portion of the reinforcing column (8) is linked to a reinforcing beam (9L) fastened to an existing beam (1 L) integrated with a floor slab (5L). The upper portion of the reinforcing column (8) is linked to a reinforcing beam (9U) fastened to an existing beam (1 U) integrated with an upper-floor floor slab (5U). The reinforcing beams (9) fastened to the same existing beam are discontinuous with right and left adjacent reinforcing beams thereof.

Whereas present invention discloses to protect and to increase the strength of the existing structure, the interconnecting columns and beams are inserted in slotted groove of the existi ng structure.

3. The Document D2 does not discloses use of Foundation Column with fin shape propping and the reinforced wall structure is first reinforced with bottom beam- slab rebars and then constructed with the help of hook shaped locking mechanism which will be then reinforced with columns and upper beam-slab as in present invention.

Document D3 concerns a pillar (A,B) for realization of structural anti-seismic node (A, B, 100, 200, 300, 400). The differences between Document D3 and present invention are as follows:

As disclosed in D3 uses an anti-seismic node that foresees at least two identical pillars as described and overlapped one to the other whereas in present invention to protect and to increase the strength of the conventional horizontalA ertical/inclined structure frame A BCD (Fig.2), additional Rhombus Shaped, Diagonal Cross, Rectangular Shaped, Corner, Plus Shaped, Radius Beams, Semi-Quarter Circular Shaped Beams and hence additional joints of all [Fig. 5 To Fig. 64] are provided at plinth level, above plinth level 40

and at upper multiple levels to increase additional multiple strength at great extent to the constructed frames of the structure for new as well as for existing (old) construction.

The present invention has addressed a long standing problem of construction of buildings, having higher resistive strength against the seismic shocks. Neither of documents D1, D2 and D3 suggest and/or claim Foundation column with Fin shape propping and interlocked reinforced wall structure as claimed in present invention, thus maki ng the present i nventi on i nventi ve and non obvi ous to the Person Skilled in the Art

In reference to the Item VII, the defects identified have been removed owing to the amended claims.

In reference to the Item VIII, the Claims have been amended to bring the clarity as per the requirements.

Therefore the subject matter of new claim(s) 1 ^" 7 differs from D1, D2 and D3. Hence it is submitted that the present application meets the criteria of Article 33(1) of PCT.
