Description

Irregular hollow building block with interlocking tenon and mortise and its use

The present invention relates to a kind of its globality of tension, shear strength and enhancing that can improve the building masonry, lead the production and the application problem thereof of the wall body building material of ductility, is civil works antidetonation (shatter-proof) anticracking in the Industrial and Civil Engineering technical measures of setting up defences.

This natural calamity of earthquake is very big to the mankind's threat, ruinous earthquake when outburst because building wrecks the collapse loss that causes the most serious.For addressing this problem, alleviate the disaster degree of violent earthquake, regulation begins to set up defences when design intensity 7 is spent in " industry and civilian construction earthquake resistant design code ", makes building when being equivalent to the earthquake effect of design intensity, still can continue to use.When carrying out structural seismic intensity mechanics check computation, regulation and stipulation: design intensity 7 is spent, and needs to consider the seismic load of horizontal direction, can check respectively at two major axes orientations of building.When design intensity is 8 degree, 9 when spending, the contour gentle structure of cantilever construction, long span structure and chimney should check the effect of vertical seismic load, and should act on simultaneously under the structural worst situation with vertical seismic load by horizontal earthquake load and check.And be defined in when carrying out the building aseismicity design, consideration place and ground are selected effective earthquake resistant structure scheme and building size to the favourable position of providing fortification against earthquakes, and guarantee that ductility is led in the globality and the connection of structure, note alleviating the deadweight of building body, measures such as raising construction quality are set up defences.Current, in the work of building structure seismic design, adopt such as good structural concepts of anti-seismic performance such as frame construction, frame-shear wall structure, shear wall (cylindrical shell) structures mostly, but the construction costs height, a lot of engineerings still need be used brick mix structure.Multi-layer brick house is then between buildup layer

The method of collar tie beam and aseismatic structural column realizes providing fortification against earthquakes.Yet these structural concepts and fortification against earthquakes all are higher aspect construction costs, and the building three material quantity of consumption are also big, also fail to embody the deadweight that alleviates the building body.One hand tile described in the nation-building ministry standard " small hollow concrete block architectural design and construction regulations (JGJ14-82) " (hereinafter to be referred as " rules 82 ") is the wall material reforming achievement, has lot of advantages.But facts have proved that lower along tension, the shear strength of horizontal straight joint, relatively poor to the antidetonation anti crack performance, the construction measure that adopts arrangement of reinforcement to fill out stem stem in the rules is implemented the seismic crack problem of setting up defences.Patent of invention (the application number: 86106736 of " application of small difference type building-block in the building structure antidetonation ", the applying date: be on the basis of " rules 82 " 86.10.21.) by sublating, reform and innovation, release the one group of small difference type building-block that can sting raft lock connection mutually, improved greatly its masonry tension, shear strength and its globality and connection lead ductility, can have structural system of one's own, satisfied the requirement of seismic crack, through the anti-seismic performance technical appraisement, 9 degree earthquakes can be resisted in five floor rooms under the situation that does not add any construction measure.When design intensity improves or building storey when increasing, still can in masonry, fill out the hole by arrangement of reinforcement.Only weak point is for being difficult to the elongated reinforcing bar of configuration level and need joining door and window in addition in masonry

Lintel, building block are only being grown to carrying out snap close: its short still has may waiting of displacement, so still need continue to improve and refresh, makes effect better.U.S. Pat 4475326(denomination of invention is " interlocking building block ") one group of building building-block that reciprocal interlocks disclosed, the configuration of two end faces of its master ga(u)ge lattice building block is identical, vertical tenon and vertical groove on a pair of linea angulata that lays respectively at two of end faces are respectively arranged on each end face, a pair of tenon and groove and another tenon and groove are separated from each other on end face and each is near a sidewall, the top and bottom configuration of building block is identical, respectively there is " h " shape tenon that vertically stretches out with vertical tenon and vertical groove disjunctor at the two ends of each face, flank during the centre of top and bottom has laterally has a brachmorphy locating piece on the middle flank.This group building block is made by the polyurethane foam material.Though building-block is built in this establishment can be in length to all carrying out snap close with short, its shortcoming is a complex structure, and the weight capacity of building is poor.

The purpose of this invention is to provide one group of concrete abnormity Hollow blocks that has that four faces can reciprocal interlock and can the elongated reinforcing bar of configuration level in its masonry.

The object of the present invention is achieved like this, the left end of master ga(u)ge lattice building block has a vertical tenon, right-hand member has a vertical groove, vertical tenon and vertical groove all are positioned on the longitudinal centre line of building block, and level is also orthogonal to the tenon disjunctor up and down with it respectively, the cross section of vertical tenon is trapezoidal, and with the cross section complementation of vertical groove, level is concave shape to tenon up and down, there is the groove of symmetry at the middle part of top and bottom, the turning of groove is the right angle, the centre of building block helps in having laterally, giving to the longitudinal centre line of tenon upper edge building block in level up and down and to stay groove, be " building block of A type " to master ga(u)ge lattice building block code name of this group building block, and two square fillet holes are established in A type building block centre.The level of the concave shape above the A type building block right-hand member is in place after tenon is turned an angle of 90 degrees to the left or to the right together with vertical groove, the wall thickness of adjustment middle rib.Right wall edging becomes the special-purpose building block of turning left or turn right in " L " turning again, and giving its code name is " Type B building block ".The level up and down of A type building block is constituted up and down level to little tenon to tenon contraction in length to neat inwall, above the front or the configuration of back as the recessed empty shape level of former left end to the configuration of tenon together with vertical groove, help in inciting somebody to action and be adjusted into two middle ribs, one macroscopic void is arranged in the middle of the building block, respectively there is a small holes on both sides, becoming another again with special-purpose building block "T"-shaped, that " ten " shape connects node, is " building block of C type " to its code name.With A type building block contraction in length 1/4th, one area of bed of the vertical tenon of left end is with corresponding one the same of A type building block, right-hand member up and down level foreshortens to neat inwall to tenon length and constitutes little tenon, two holes of chien shih were equally big during middle rib can be adjusted and be located at, also can stay be located at original position make two holes small one and large one, be to cooperate the building block of C type to use or cut length in building axis line middle part work accent and use, giving its code name is " D type building block." with two merging of A type building block; and wherein one the vertical tongue-and-groove in two ends removes stretching; left and right sides wall edging becomes planomural; adjust the wall thickness of merging place cross middle rib; become the fastening fissure of displacement building block that another kind is exclusively used in pilaster again; giving its code name is " building block of E type ", and the cross middle rib is divided into four holes with the building block middle part.The building block of A type is cut in the middle of middle rib, adjust the wall thickness of cutting section middle rib, become another type building block again, giving its code name is " building block of 1/2A type ".A kind of solid auxiliary block, only single-ended have vertical tenon or a vertical groove, vertical tenon or vertical groove with its up and down level to the little tenon disjunctor of sky groove and orthogonal, and with a vertical projection disjunctor, formed special-shaped block is " building block of F type " to this code name.The F type building block of 1/2A type building block is filling a vacancy of wall termination or the training of door and window limit, and the building block of 1/2A type also is used for the coordinating block of attached wall pilaster.By the walling of block that above-mentioned building block is organized, can the piece piece four faces fastening that reciprocal interlocks up and down, form vertebration walling.

Irregular hollow building block can be referred to as wall material, also can be referred to as the concrete precast member, and it mainly is that raw material is produced with the concrete, because the plasticity of concrete brings convenience for various moulding.The present invention only need can carry out the production of this building block according to the various recessed size recast mould of this building block on the equipment of original production small-sized hollow building block.The production appearance and size of this building block requires accurately, and its error just is being zero negatively to be 3 millimeters and to be certified products.Therefore, no matter manual production or machinery production all should have corresponding process implementing to ensure its quality specifications.

Know that from the masonry structure textbook one of key factor of influence (reduction) masonry intensity is mortar (mortar joint).This building block has higher height and has the characteristic that four faces can tightly be interlocked and be fastened, only need a small amount of high-strength mortar to bond when therefore building by laying bricks or stones or remedy the error of profile, when the surface is very regular in addition laid dry also be fine.This has just created condition for making full use of the inherent power of material (member) with the raising work efficiency that reduces cost.It is to prepare the elongated reinforcing bar of configuration level and be provided with that the central authorities of every protrusion raft tenon all give the groove that leaves 2 * 3 centimetres, when the needs arrangement of reinforcement, vertically lays along the hole of building block, and level is given to edge and stayed the groove laying, fills out the filling concrete then.When need not arrangement of reinforcement, also available mortar (it is better to mix a little glass fiber) is filled and led up when building by laying bricks or stones, also can play the tension effect.Water, fulgurite road can be along in the masonry holes and give staying in the groove and lay, and is very convenient.

In architectural design, be " basic module " with 100 millimeters still, so this building block plane in all cases controls and organize block, can both be fit to the size numerical value of the various standard widths of a room in an old-style house (depth) according to China's " building unified modular system ".To selecting for use of door and window model specification, can adopt the standard typical drawing, but also otherwise designed, but should notice that the specification of non-100 millimeters carries is inapplicable, and should be arranged at suitable position.Mechanics check computation is still followed country's " industry and civilian construction earthquake resistant design code (TJ11-78) " and is carried out.Aspect building operations, still carry out with reference to " rules 82 ", difference is that each special-purpose building block is exclusively used in node corresponding, D type building block double as length adjustment piece, and 1/2A and the building block of F type are used for the dutchman on wall end and limit, door and window hole, all the other are complete in A type concrete block masonry, and various building block can not be gone here and there usefulness mutually.Construction technology is very simple, and is clear understandable, without any specific (special) requirements, implements easily.

Fig. 8 is the masoning method at exterior wall " L " turning 12, builds a wall with the building block of A type, and 12 places, turning divide to turn left, turn right with the Type B building block, alternately rise.Fig. 9 is the masoning method of the "T"-shaped connection node 13 of wall, builds in meeting earlier with the building block of C type and places longitudinal and transverse crossing point of axes place, and three all connect the building block of A type, goes up a skin again with in the middle of the A type building block fastening, fastens both sides with the building block of D type, repeats alternately rising.Figure 10 is the masoning method that wall " ten " shape connects node 14, meets to build in the crossing point of axes with the building block of C type and puts, and horizontal block both sides are vertical with the building block of C type in meeting with the building block of D type, then form crosswise, and every afterwards skin reverses the rotation of an angle of 90 degrees intersection and rises.Figure 11 is the masoning method of attached wall pilaster 15, builds by the pilaster axis with the building block of E type earlier and puts, one side the A type that still the connects building block of wall, a last skin is built a wall with the A type building block fissure of displacement, builds with the building block of 1/2A type and protrudes pilaster (the raft tenon is placed in the middle), repeats alternately to rise.A type concrete block masonry is used at the middle part of walling entirely, only when not meeting length dimension, regulates with the building block of D type.The various connection nodes of house walling just have above-mentioned four kinds of open types usually.The greatest difficulty that the design deformed block runs into usually, the problem how just above-mentioned connection node is handled.Above-mentioned four kinds of masoning methods have been arranged, can make the deformed block masonry have structural system of one's own.From Fig. 8 to Figure 11, as can be seen, utilize tongue-and-groove interlocking principle to make the deformed block can tight snap closes, form firm integral body at four faces, improved greatly walling tension, cut intensity, realize that purpose is prevented in the throwing of earthquake resistant engineering (shatter-proof).From With know in the concrete structure textbook that the tension of concrete, to cut intensity be half of basic compressive strength cubic root, by this calculating, each tenon can bear more than 200 kilogram draw, shear stress, be a kind ofly can bear the wall that level is drawn, shear stress is bigger.Because deformed block has the characteristic (function) of the tight interlocking of four face tongue-and-grooves, it is discrete that its masonry is difficult for, and do not bond (being laid dry) even there is mortar, draws the influence of cutting intensity also little to it.This is for reducing engineering cost, and advantage has been created in rapid construction etc.From a few width of cloth figure, also can find out in walling, to have to give together and stay groove 15, can in groove, lay horizontal reinforcement.Can in groove, lay horizontal reinforcement 16 on the door and window top, in hole, hook again and tie, as shown in Figure 12, fill out the grout hole with concrete again, need not to join in addition lintel, if cast-in-place with perpendicular muscle 17 Floor, in the perpendicular muscle 17 straight cutting plates, better in company with pouring with plate.When (being necessary) if be necessary, giving along the level up and down of building block and to stay groove 5 to lay horizontal full-length reinforcing bar 16, tie perpendicular muscle 17, again this skin (also can two skins or many skins) is filled out to irritate with concrete and form " collar tie beam " according to engineering mechanics checking computations explanation.Or connect node at attached wall pilaster 15(or each) hole in cloth muscle concrete fill out hole and underfloor Beam (or " collar tie beam) cooperate, can form " phantom frame ".Or in the hole of masonry, lay perpendicular muscle 17 and giving staying and lay horizontal bar 16 in the groove 5, as shown in Figure 13, fill out with concrete then and irritate its hole, form " simulation shear wall ".Utilize above-mentioned measure, this building block can be widened be applied to more (height) layer construction work in.

Arrange piece work by the quantity surveyor before building by laying bricks or stones, (multistoried building is to avoid its basic uneven subsidence should collar tie beam should be set with collar tie beam on its basis according to architectural plan.When walling design has perpendicular muscle 17, give in the relevant position of collar tie beam and to bury the bar with hooked end head.) on the surface with the ink fountain bullet mark in the body of wall, the sideline, mark position, door and window hole, other piece is discharged in the special-purpose building block at each point of contact of discharging more earlier.For example 1. 1. transversal line intersect at A, 1. B, 1. C 3 points with each longitudinal axis on the architectural plan, 1. A is that the center line distance of "T"-shaped connection node 13 is from being 2700 millimeters to 1. B for " L " turning 12, the B piece is in 1. A point traverse (along the A axis), the C piece in 1. B point along putting (horizontal B axis), at this moment the B piece account for length 100, C piece account for length 200 totally 300 millimeters be referred to as " starting size " (wherein tenon and groove offset), the piece number in the middle of calculating is: (2700-300) ÷ 400=6A piece.The B piece becomes along putting (horizontal A axis) during to second skin, and becomes A piece traverse (along the B axis) on the C piece, and starting is of a size of 400 millimeters, (2700-400) ÷ 400-5A piece+1D piece.Center line distance from 1. B point to 1. C " L " turning 12 is from being 4500 millimeters, with the B piece in 1. C point along putting (horizontal C axis), its starting is of a size of 500 millimeters, (4500-500) ÷ 400=10A piece, its epithelium becomes traverse (along the C axis) because of the 1. B of C place piece, starting is of a size of 200 millimeters, (4500-200) ÷ 400=10A piece+1D piece.All the other all arrange piece by this principle.Also can be at "T"-shaped point of contact 13 earlier with A piece row piece.Sequence at the architectural plan subscript earlier before can also arranging piece at the scene.After the confirmation of row's piece, can begin to build by laying bricks or stones.At this moment, Lian Pugong can build by laying bricks or stones.After finishing building a skin or two skins, fill out hole 50 millimeters thick that steel bar end is not stayed in filling, to strengthen the shear strength of article one ash suture with No. 100 concretes.

When cold district requires the walling heat-insulating property high, can use double hole instead in the building block of exterior wall, the building block of A type such as Figure 1A, Type B building block such as Figure 15, the building block of D type such as Figure 16.Also can in hole, brush way solutions such as (or filling) heat insulating material.

Fixing of door and window can be given in dutchman and be buried woodbox, and nail is fixed; Electric drill jewel hole after also can good and sound doorframe and window frame, dowel fixes.Water, fulgurite Lu Yike is along in the hole or give staying in the groove and lay, but inconvenience during maintenance.

What need after this tongue-and-groove irregular hollow building block with interlocking more is applicable to and is badly in need of room, barracks or uses certain hour to remove uses the room temporarily.At this moment, on solid ground, adopt this building block to carry out laid dry, the end and the building block level on top give stay in the groove and in the hole at four big angles (if house long in the suitable hole in centre) with elongated iron pull bar reinforcing.Cover roof system, good and sound door and window, the arrangement terrace, it is indoor that table is stuck with paste (or whitewashing), can use.When not required, unload door and window, lift except that roof system, unclamp and reinforce the iron pull bar, pull down this building block from top to down, it is stand-by all to transport the strange land, very convenient.

This tongue-and-groove irregular hollow building block with interlocking still can be applicable in the masonry of the square structure of bar such as Square Factory Chimney, retaining wall, enclosure wall.

Some statistics from newspapers and periodicals disclose: in national nearly 7 years, solid clay brick on average greater than 26,300,000,000 speed fast development with every year, and 1988 annual productions have broken through 400,000,000,000.Produce the annual power consumption of these bricks and surpassed 5,000 ten thousand tons of standard coals, fetch earth and ruin the field and reach 70,000 mu.Go down like this, the field scholar that the mankind depend on for existence will be destroyed year by year.Therefore, greatly develop novel wall material, be significant.

In sum, the technology of the present invention is used in earthquake protection area, can earthquake resistance and prevention; Use in non-earthquake protection area, but also anticracking has good technical economic benefit and very high social utility's value.And technology brief is understood understandable, implements easily, and is very suitable to vast town and country wide popularization and application.
