Description
Technical field
The present invention relates to easy construction and have the plane grid hollow concrete plate of good sound insulation value and the lacing wire that is used for this concrete slab.
Background technology
For guaranteeing that the high-rise building and the building of big room space need, what adopt now is that embedded object is embedded in the steel concrete intralamellar part, makes its hollow increasing thickness, thereby improves its intensity, and weight reduction simultaneously improves the various job practicess of sound insulation value.What this class embedded object adopted is to be the hollow tube of representative with the helix tube, box-shaped goods that the deck plate bending process is made and waterproof carton etc.In addition, in patent gazette such as Japanese Patent Publication 57-47007 number, special public clear 58-20768 number, proposed with the synthetic resin foamed product, its base plate with thin precast unit has been fixed into the job practices of integrally formed mould as embedded object.
These job practicess always can realize the purpose of weight reduction, and wherein majority is that hollow bulb is only at a unidirectional concrete slab that direction is continuous.Because the structural load of this unidirectional concrete slab transmits in one direction, therefore, will be subjected to all restrictions in design for the concrete slab of 4 limits supporting.The two-way concrete slab that can address this problem has been proposed in the Japanese Patent Publication 63-49025 patent gazette.But, for the two-way hollow concrete plate that adopts hollow tube, must be to each workpiece, every block concrete plate carries out the distribution of hollow tube, bothers very much in the design, owing to need the hollow tube of all size, so store keeping is very miscellaneous, it is very inconvenient to construct, and has variety of problems.
Improve as essence always hollow concrete board construction method, Japanese kokai publication hei 9-25019 patent gazette has proposed to be in by mould in the little space of gridiron pattern shape that the latticed upper reinforcement that ties up and lower rebar be divided into, place a plurality of light weight objects, the job practices of carrying out concrete pouring.In this two-way concrete slab construction method, as the light weight object, adopted the foamed plastics of cube, cylindrical or bird-caging, this light weight object is embedded in the above-mentioned little space of the very rule that forms in the concrete slab, forms the two-way concrete slab with the i beam cross sectional shape that connects on the both direction that intersects vertically.Adopt such structure, store keeping is convenient, also as long as the light weight object is placed in the above-mentioned space ties up with auxiliary reinforcement, can form high-precision two-way concrete slab easily in the construction.
But there is following point in the two-way concrete slab described in the above-mentioned communique.When forming concrete slab skeleton A shown in Figure 13, will be on lower bolster 21, earlier bind auxiliary reinforcement 24a in the centre of lower rebar 22a, bind auxiliary reinforcement 24b in the centre of lower rebar 22b, tie up upper reinforcement 23a and 23b then, after placing light weight object 25, also between upper reinforcement 23a and 23b, bind auxiliary reinforcement 24c.This is that auxiliary reinforcement 24c is the top of light weight object 25 fixedly because will use the fixedly bottom of light weight object 25 of auxiliary reinforcement 24a and auxiliary reinforcement 24b, light weight object 25 come-ups when preventing fluid concrete.In addition,, therefore just formed light weight object direction up and down owing to be formed with the groove of putting auxiliary reinforcement on the light weight object, must be when construction by its placement light weight object in the right direction.Therefore, spend the expense of tying up auxiliary reinforcement, it is also pretty troublesome to place the light weight object, and the result causes the increase of construction cost.
Summary of the invention
Therefore, the purpose of this invention is to provide a kind of problem that can solve two-way concrete slab always, easy construction also has the plane grid hollow concrete plate of good sound insulation value and the lacing wire that is used for this concrete slab.
The present invention is a kind of by being in by concrete slab in the little space of gridiron pattern shape that latticed upper reinforcement that ties up and lower rebar be divided into, the plane grid hollow concrete plate of placing the light weight object and forming, it is characterized in that this light weight object is solid or hollow light weight spheroid, its diameter makes it can not pass through its side by the end face in this little space, and the lacing wire that is provided with on upper reinforcement is fixed on institute's allocation with this light weight object.
In plane grid hollow concrete plate of the present invention, the light weight spheroid can be 10-50% to the volume ratio in little space.
The present invention still is the lacing wire that a kind of plane grid hollow concrete plate is used, it is characterized in that constituting with some unit of on this auxiliary reinforcement, fixing downwards by at least two auxiliary reinforcements that are set in parallel between the adjacent upper reinforcement, can pack in the little space that the upper reinforcement of tying up into grid-shaped forms in this unit, the light weight spheroid is fixed on institute's allocation.
In lacing wire of the present invention, said units can be to curve saddle-shaped steel hoop, preferably its foot outwards bending respectively.In addition, said units also can be obliquely installed alternately by the bending clamping reinforcing bar that forms recess and form, and the end of this clamping reinforcing bar does not connect mutually.
Plane grid hollow concrete plate of the present invention because the light weight object that is configured in the little space is a spheroid, needn't be adjusted the direction of light weight object when therefore constructing.The lacing wire of the application of the invention is fixed on institute's allocation with the light weight spheroid and is very easy to, and can realize the design strength and the sound insulation value of concrete slab.In addition, by dwindling the interval of lower rebar and upper reinforcement, dispose littler light weight spheroid, obtain good balance between weight reduction and the rigidity, simultaneously by many little spaces and be arranged at the propagation that wherein light weight object has been blocked sound, confirmed to weaken the sound of certain wavelength, particularly the dormitory can be improved obviously, restaurant, school, the warehouse, debatable ground impact sound such as sky parking.

The specific embodiment
Embodiment to plane grid hollow concrete plate of the present invention (hereinafter to be referred as " concrete slab ") describes with reference to the accompanying drawings, but the present invention is not limited to these embodiments, present invention includes the replacement or the design alteration of each key element in realizing the object of the invention scope.
Fig. 1 is the plan view of an example of the skeleton of expression concrete slab, and Fig. 2 is the vertical cross-section diagram along its A-A ' line, and Fig. 3 is the vertical cross-section diagram along its B-B ' line, and Fig. 4 is that expression does not have the stereogram under the concrete state.
The lower rebar 2b that the represented concrete slab skeleton of reference notation S has on the lower bolster 1 of the concrete slab parallel lower rebar 2a that ties up and intersects vertically with 2a, and same upper reinforcement 3a and 3b, they have formed and have been divided into the little space 4 of tessellated grid, place light weight spheroid 5 respectively in a plurality of little spaces 4.Downward lacing wire is set on upper reinforcement 3b, prevents moving of light weight spheroid 5.Lower rebar 2b and upper reinforcement 3b are fixing with suitable thickness reinforcing bar 7.
Lower bolster 1 can be with the template of system such as wooden or plastics, but also can replace the roof panel job practices that adopts roof panel, or adopts the half precast plate job practices or the full precast plate job practices of precast plate.
(lower rebar is the interval between 2a and the adjacent 2a at interval between the main reinforcement, interval between 2b and the adjacent 2b, upper reinforcement is the interval between 3a and the adjacent 3a, the interval between 3b and the adjacent 3b), preferably the design thickness according to concrete slab changes.This is because according to the size of the varied in thickness light weight spheroid 5 of concrete slab, helps keeping the rigidity of concrete slab, alleviates its weight simultaneously, improves sound insulation value.In addition, the interval between lower rebar 2a and upper reinforcement 3a can be determined according to the thickness and the concrete pouring thickness of concrete slab.
Thickness reinforcing bar 7 needs only fixedly upper reinforcement and lower rebar, and there is no particular limitation, but the reinforcing rib about the most handy 10-15mm Φ is pressed the certain-length cut-out, and the one end is curved acute angle, and the other end roughly curves the right angle.In addition, for the present invention, also can be with pressing the reinforcing rib that certain-length cuts off, with for example welding, bonding, methods such as binding are fixed upper reinforcement and lower rebar.
The light weight spheroid 5 that the present invention is used, have make its can be by the end face in little space 4 can not be by the diameter of its side.The diameter of light weight spheroid 5 (Φ) then may make it pass through the side as identical with the side in little space 4 or littler than it, goes in other little space, or moves therein.In addition, the size as this Φ is not less than and can then can't be placed in the little space 4 by the diameter of little space end face.Like this, by to light weight spheroid 5 with respect to the placing restrictions on of the size in little space 4, in a little space, just in time put a light weight spheroid into.
Want to satisfy this condition, usually just passable as long as prepare the spheroid of about 6 kinds of S (Φ 125mm), M (Φ 150mm), L (Φ 175mm), 2L (Φ 200mm), 3L (Φ 225mm), 4L (Φ 250mm), these just go for thickness at 225mm to 350mm concrete slab, then go for the concrete slab of any thickness with the light weight spheroid of any diameter.
The shape of light weight spheroid can be a spheroid as much as possible, and more or less problem on deformation is little, but resemble the oval ball of rugby ball shape or the spheroid of egg shape, because directionality is arranged, so will adjust direction during construction.As offer concavo-convex at the light weight spherome surface or shallow slot then can with concrete interlock better.The material of light weight spheroid is not placed restrictions on especially, as long as in light weight, and handling ease, foamed plastics for example, hollow bodies or the like.Particularly in light weight, the foam styrene of rigidity is arranged, the hollow body of foamed plastics systems such as foamed polyethylene is very suitable.
Because the present invention has used and do not had the light weight of directionality spheroid,, just can correctly in each little space, place a spheroid as long as light weight spheroid 5 is thrown into.And during with directive spheroid always, must the direction of each spheroid be adjusted, efficiency of construction just greatly reduces.
In the present invention, the ratio in light weight spheroid and little space (volume ratio) is preferably about 10-50%, and volume ratio is as less than 10%, and the weight saving of concrete slab is few, and sound insulation value is not improved, and will reduce as the rigidity that surpasses 50% concrete slab.Consider from the rigidity of concrete slab and the balance of weight reduction, be preferably 15-35%, be more preferably 18-32%.Table 1 has been represented concrete slab thickness, gap, cross section (gap between lower rebar 2a and the upper reinforcement 3a), void diameter, the preference of volume ratio, but the invention is not restricted to this.

After in many little spaces 4, having placed light weight spheroid 5 respectively, above upper reinforcement 3b, settle lacing wire 6, itself and upper reinforcement 3a are tied up.Only spheroid is put into little space 4, when fluid concrete, light weight spheroid 5 may float.Run out from little space 4, focus on the surface of concrete slab, leave fixed position.The present invention is fixing with light weight spheroid 5 with lacing wire 6, has solved this problem.This lacing wire 6 also can be used as the construction movements and postures of actors in row establishes the engineering of pipeline, it can prevent the advantage of light weight spheroid breakage in addition in addition.
Below, with reference to accompanying drawing the instantiation of concrete slab of the present invention with lacing wire described.Fig. 5, Fig. 6 and Fig. 7 are stereogram, plan view and the front views of an example of expression lacing wire, and Fig. 8 is the plan view that lacing wire constitutes the unit, and Fig. 9 is the vertical cross-section diagram along its A-A ' line, and Figure 10 is the vertical cross-section diagram along its B-B ' line.
Lacing wire 11 is by two auxiliary reinforcements 12,12 ' and downward a plurality of unit 13,13 ', 13 fixed thereon ", 13 , 13 " "---constitute.Unit 13 shown in Fig. 5 is the shaped as frame for sealing in Fig. 8.In Fig. 9, be the Fuji shape, in Figure 10, for there not being the box-shaped at top,, be fixed in the above being under the state of the shape of a saddle on auxiliary reinforcement 12 and 12 '.The little space shown in Figure 1 of can packing into, this unit 13, light weight spheroid 14 are accommodated in the space that unit 13 forms, and light weight spheroid 14 is fixed, and can not move.As shown in the figure, this auxiliary reinforcement have two just much of that, but also can have more than 3, have only one as auxiliary reinforcement, lacing wire will be that rotating shaft is rotated with it, so auxiliary reinforcement and upper reinforcement must be fixed with methods such as welding.The thickness of auxiliary reinforcement 12 and length are arbitrarily, the reinforcing bar of for example available 6mm Φ, and about 1.9m is easy to deal with for total length, and it is also easy to design and construct.
The manufacturing of this unit 13 can, for example reinforcing bar is curved rectangle, with the welding of end and end, make the frame of its rectangularity, again it is curved the shape that formalizes.Then, the bending of unit 13 towards being placed down on two auxiliary reinforcements 12 and 12 ', is welded infall, allow both fix, just can be made into lacing wire 11.In the above-described embodiment, the foot 15 of unit 13 outwards bends, but the lacing wire 11a of the unit 13 that the 15a of employing foot does not as shown in figure 11 bend also within the scope of the invention.The foot 15 outwards advantage of the lacing wire 11 of bending is to pack little space into conveniently, and is good with light weight spheroid snapping, piles up easily when taking care of with transportation.
Another example to lacing wire describes with reference to the accompanying drawings.Figure 12 is the stereogram of another example of expression lacing wire.Lacing wire 16 is without the unit 13 of the lacing wire 11 of Fig. 5, and replaces fixing unit 18.Unit 18 is formed by the bending clamping reinforcing bar 19 that forms recess, unit 17, and 17 ' is obliquely installed alternately.Example shown in this embodiment is the foot 20 that bending is arranged, but also can be with the bending of foot portion.
Concrete slab lacing wire of the present invention is not limited to above-mentioned embodiment, can carry out various design alterations.Though lacing wire also can consider to adopt wire gauze, netted muscle such as gauze wire cloth, but netted muscle can allow the light weight spheroid move in torrent when fluid concrete, is difficult to the effect of performance lacing wire.
As the preferred implementation of concrete slab of the present invention, can be a kind of number that has increased little space 4, dispose the concrete slab of the cubicle formula of littler light weight spheroid.This cubicle formula concrete slab ratio plane grid hollow concrete plate sound insulation value always better (Japanese Utility Model, number of registration 3082676).Increase cubicle, can dwindle the interval of main reinforcement in length and breadth, dwindle the gap, cross section (with reference to table 1) between lower rebar 2a and the upper reinforcement 3a simultaneously.Though number can also increase between little space, owing to construction cost also will increase, so should determine to count therebetween from the angle of input-output ratio.
During concrete slab construction of the present invention, can be in having the mould of above-mentioned skeleton fluid concrete, slough template after the curing and get final product.This plane grid hollow concrete plate also can be made the concrete slab skeleton at the scene, carries out site operation, can also carry out construction of half concrete prefabricated board or the construction of whole concrete precast plate with precast plate.
