ARRANGEMENT FOR A MODULAR BLOCK WITH WEDGE-SHAPED COUPLINGS

Description

INTRODUCTION

[0001] The present application for patent refers to a novel ARRANGEMENT APPLIED TO MODULAR WALL BUILDING BLOCK WITH WEDGE-LIKE COUPLINGS, especially a modular wall building block, made of polymer, the locking and centralization of which occurs by means of male and female wedge couplings of the side outer fillet in concordant profile recess located on the opposite wall, and also between the quadratic projections, on the top face, in at least eight inner single-wire braids, whereby enabling, by overlaying the blocks, to make a synthetic masonry assembly system used in any type of construction.FIELD OF APPLICATION

[0002] The field of application of the innovation now claimed is that of the construction industry, more specifically in the construction of synthetic masonry, without bonding elements, used in residential units, bus stops, schools, stores, etc.STATE OF THE ART

[0003] The current state of the art anticipates some patent documents that address bricks and blocks endowed with couplings used in the construction of masonries, such as DE 19903287 A entitled "PROFILED HOLLOW BRICK" - refers to a brick to be stacked upon each other, comprising profiles that assist in locking when the parts are stacked. Cone-shaped profiles on the sides of the brick form male and female joints, and other cone-shaped profiles extend around the circular compartments, assisting in the centralization of the bricks.

[0004] By using cone-shaped profiles having a regular size (on the sides) the brick of the prior art above does not provide perfect locking between the parts, but solely a juxtaposition, and this fact should be offset, after assembling the masonry, by filling in the circular hollow compartments of the bricks with some material, such as, for example, light concrete, pumice stone, expanded clay, etc. Therefore, with the brick of the document cited above, it is possible to mount a wall using the couplings, but it is compulsory to complement it by filling in with material / subsequent filler.

[0005] MU 8700558-1 U2 entitled "ARRANGEMENT APPLIED TO BLOCKS USED IN CIVIL CONSTRUCTION" - refers to a block based on the "Lego" model for masonry construction, susceptible to assuming three arrangements, with one, two or three central square holes, the highlight of which is having two, three and four horizontal circular holes for the passage of pipelines and other facilities. Bordering each central hole there is a square base for laying the upper part, also being endowed with a fillet in high relief on the smaller-sized side, aligned with the circular bore, and low reliefs on the complementary wall. Both the square holes and the circular bores act as passage for reinforcement / ironwork.

[0006] The blocks of the prior art above only have male and female couplings, which do not offer safe / stable fastening by not promoting sufficient mechanical interference. So much so that the report states that after assembly, the masonry should be reinforced at least with plasterwork. Further, the relative positioning of the high and low relief obliges the use of certain arrangements of blocks so that the couplings coincide, which also limits the constructive system.

[0007] BR 112019021073-3 entitled "MODULAR BLOCK FOR ASSEMBLING PASSAGE BOX" - consists of a single cobblestone block endowed with a square male fitting having a central bore for the passage of locking tether on the top face, which faces a female fitting, also square, on the inner face of the part, which, together, are for overlaying and juxtaposing the blocks; which keep a laterality thanks to the male couplings represented by a prismatic appendix and a female fitting represented by a slot on the side and opposite side faces; the block is complemented by a locking extension that prevents the entry of residues inside the box when mounted on the frames.

[0008] The block of the prior art above does not promote perfect locking on the side walls, as same is implemented by fitting the appendix in the slot, there being no type of interference. Even the centralization of the block, when laid over the parts, is not effective because despite being wedge-like, it has a reduced contact area, which leaves room for kinks, in detriment to the stability of the masonry.

[0009] WO2018 / 184080 - MODULAR FIXING BLOCK FOR JUNCTION BOX, the invention consists of a single block provided with a quadrangular male fitting with a central hole for the passage of a locking rod on the upper face, which opposes a female fitting, also quadrangular, on the lower face of the component, which fittings, together, are used for the overlapping and juxtaposition of the blocks; these remain side by side due to the male fittings represented by a prismatic appendix and a female fitting represented by a groove on the lateral faces and opposite side; the block being complemented by a locking extension that prevents the entry of waste into the box when assembled on the frames.

[0010] The block has a male and female fitting. On the width face of the block, a tooth is positioned only in the basal portion, while on the opposite side there is a notch with the same dimensions as the tooth. This small fitting does not have a locking mechanism on the entire face of the block, unlike the proposed block, which has a wedge-shaped fitting, consisting of a fillet considered a male fitting, with a trapezoidal cross-section of increasing dimension from the end to the base of the block. Unlike the fillet, there is a recess with the same characteristics as the fillet, assuming the female fitting.

[0011] WO0177456 - A CONSTRUCTION SYSTEM - a construction system for constructing a wall of a structure, comprising a number of plastic building blocks and a number of locating pins. The building blocks each have a generally rectangular shape and have a first end, a second end, a front side, a back side, a top side and a bottom side. The top and bottom sides of each building block define flat mating surfaces and a number of interlocking formations in which the locating pins are receivable for locating adjacent building blocks in adjacent layers, relative to each other. The first end of each building block defines a male dovetail formation and the second end defines a complementary female dovetail formation, to locate adjacent building blocks in the same layer, in relation to each other. Each building block defines passages that extend between the upper and lower sides of the building block.

[0012] The block has a male and female fit, by a wedge configuration, in the width of said block. The wedge fit is sized symmetrically, without any inclination, which allows that when a block fits between another, it can be removed from top to bottom or inversely, in addition to a loss of resistance of a wall assembled by these blocks, unlike the proposed block, which has a wedge-shaped fit, which consists of a fillet considered a male fit, of trapezoidal section of increasing dimension from the end to the base of the block. Unlike the fillet, there is a recess with the same characteristics as the fillet, assuming as a female fit.

[0013] US5355647 - INSTALLED TENSION MASONRY SYSTEM - a masonry wall system is constructed of concrete blocks, with interconnected insulation inserts. To provide additional structural reinforcement, a butterfly-shaped steel plate is locked to an elongated rod that passes through periodic layers of stacked blocks. The plate is locked perpendicular to the rod, to rest on top of the topmost block of the layer to which the tension or bracing is applied. A recess is formed in the top of the block to accommodate the plate, which is arched upward. A nut or threaded insert is used to press the plate down; and when the plate lies flat, the desired amount of pressure or tension is applied to the blocks. Additional layers may be applied over that to which the plate provides the tension, with additional rods and bracing plates being threaded onto the ends of the previous rods to accomplish this purpose in additional layers of blocks that form the wall system.

[0014] This is a connection between the blocks of a lower row in relation to the upper row. The block is composed of a main block and a wedge-shaped shim block, which is inserted into the gap of the main block, which is finally tied by a worm-thread rod and a support. The block of the patent application now proposed has a wedge-shaped fitting, which consists of a thread considered a male fitting, with a trapezoidal section of increasing size from the end to the base of the block. Unlike the thread, there is a recess with the same characteristics as the thread, assuming a female fitting. This fitting provides better resistance to mechanical stresses.OBJECTIVES OF THE INNOVATION

[0015] It is an objective of the present innovation to propose a modular wall building block capable of promoting effective connection both in locking and centralizing, thanks to the male and female wedge-like fitting, the fastening of which increases according to the intensity of the strength attributed in the coupling.

[0016] It is an objective of the present innovation to propose a modular wall building block which after assembling the masonry does not require filling with a bonding element.

DETAILED DESCRIPTION OF THE INNOVATION

[0021] The ARRANGEMENT APPLIED TO MODULAR WALL BUILDING BLOCK WITH WEDGE-LIKE COUPLINGS, object of this patent application, consists of a modular wall building block (1) endowed with four walls (2, 3, 4, 5), an top face (6) and two internal cavities (7, 8) wherein both the locking and centralization between the blocks (1) are prominently implemented by male and female wedge-like couplings.

[0022] More particularly, the innovation consists of a hollow modular wall building block (1), made of polymer, endowed with four walls (2, 3, 4, 5), an top face (6) and two internal cavities (7, 8) separated by a partition (9), and on the top face (6) two quadratic projections (10) are prominently juxtaposed with a central bore (11) for the passage of tethers (T) used in the constructive system, whereas on the side between the walls (2 and 5) there is a vertical extension (12), which is a vertical extension extends along a vertical edge of the modular wall building block and covers a vertical coupling between adjacent hollow modular wall building blocks that prevents the entry of residues from that point inwardly when at least two blocks (1) are joined. Both the locking and the centralization between the blocks (1) are made by male and female wedge-like couplings, such that the more pressure there is between said blocks (1) the greater the fastening achieved. On the first adjacent wall (3, 5) there is a fillet (13) with trapezoidal cross-section increasing in size from the end to the base of the block (1), which acts as guide for a recess (14), having the same cross-section and design of the fillet (13), being located on the opposed face of the adjacent walls (3, 5), that when duly inserted carries through the locking between the blocks (1) with the male and female wedge-like fitting, wherein the fillet (13) is the male part and the recess (14) the female part of said fitting. Each of the internal cavities (7, 8) has a pair of single-wire braids (15), on each of their four wedge-shaped faces, positioned so as to receive the quadratic projections (10) generating a mechanical interference deriving from the male and female wedge-like fitting, wherein said quadratic projections (10) are the male part and the internal cavities (7, 8) and respective braids (15) the female part. Accordingly, when overlaid the blocks are centralized.

[0023] A constructive variation of the hollow modular wall building block (1'), made of polymer has a smooth wall (5), that is, without the fillet (13) being used to finalize the assembly on the corners of the masonries (16).

[0024] The blocks (1) duly juxtaposed and overlaid used in assembling the masonries (16) supported on a primary frame (17) and a complementary frame (18), all the parts having through-passing tethers (T) concentric to the bores (11) of the blocks and holes (F) of the tethers per se fixed by a fastening element, such as, for example, a nut (19) susceptible to application in any type of construction such as, for example, residences and bus stops.

[0025] The present innovation now proposed is intended to encompass all alternatives and variations, modifications and equivalents that can be included in the measurements and shapes of this block.
