Description
The present invention relates generally to a kind of reinforced concrete slab structure, specifically, relates to a kind of being used for compile reinforcing bar apace and save the corrugated sheet of surface dressing work when forming a reinforced concrete slab structure.
The crowd institute of being familiar with prior art is known, and reinforced concrete structure is to use concrete as compression piece and use many reinforcing bars to make as tensioning member, therefore has a complicated structure.In order to make a reinforced concrete structure, generally a plurality of cast cover plates to be placed on the bearing surface, between the cast cover plate, leave desired gap.Then, many reinforcing bars are compiled in the gap.After reinforcing bar being compiled in the gap of cast between the cover plate, just with concrete pouring in the gap and sclerosis a period of time make concrete and independent reinforced concrete structure of steel bar overall ground formation.After reinforced concrete structure hardens fully, take off with will pouring into a mould a piece of cover plate, thereby obtain a reinforced concrete structure.Such reinforced concrete structure generally and preferably is used as building structure.
The conventional method of making this reinforced concrete structure comprises some steps: will resemble that cast cover plate the wooden cover plate is arranged on the bearing surface and many reinforcing bars are compiled in the gap between cover plate.This method also is included in will pour into a mould the cover plate separating step that cover plate takes off from reinforced concrete structure after structure is hardened fully.That is to say that the method for using the cast cover plate to make reinforced concrete structure comprises a plurality of steps, makes this method very consuming time.
Usually, the cast cover plate can be bonded on the surface of the reinforced concrete structure of making so tightly, makes to be difficult to cover plate is taken off from concrete structure.In addition, the cast cover plate can stay uneven surface on reinforced concrete structure, will make this structure carry out extra surface dressing work more like this.The cast cover plate generally is to make with the low intensive material that resembles wooden, makes cover plate be easy to damage or fracture in that it is pulled at following time from reinforced concrete structure.The cover plate of Sun Huaiing just can not be reused like this, forces the owner to spend more one-tenth and buys new cast cover plate originally, and produce a large amount of discarded cover plates.
Use the cast cover plate to make in the effort of the problem that is run in the process of reinforced concrete structure overcoming, proposed a kind of no cover plate method that integrally forms the trimming part of final reinforced concrete structure with concrete of using.
Fig. 1 and 2 shows general watt ridge cover plate method respectively, and this method is a typical example of well-known no cover plate method and has used an a corrugated watt ridge cover plate D to replace pouring into a mould cover plate.In watt ridge cover plate method, only need a watt ridge cover plate D is placed on the beam (not shown), thereby make this method save the step of arranging and taking off the cast cover plate.In addition, corrugated watt ridge cover plate D has simplified the step of laying wire or dress feed pipe, because electric wire or feed pipe can be placed in the passage that forms below the crest of corrugated watt ridge cover plate D at an easy rate.The different surface dressing work of typical method of cast cover plate also can be saved and be used to watt ridge cover plate method.Another advantage of watt ridge cover plate method is that a watt ridge cover plate D provides safe Working rack for the workman, thereby has saved common safety net from working face.Using such watt ridge cover plate D to simplify significantly makes the method for reinforced concrete structure and has shortened the engineering time.Therefore, watt ridge cover plate method is preferably used in the reinforced concrete structure of making building.
But this watt of ridge cover plate D that makes with steel gets rusty easily.In order to prevent that the steel watt ridge cover plate D from getting rusty, cover plate D must be coated with on the surface that exposes and coat.A steel watt ridge cover plate D has flat and smooth surface, makes cover plate D not form integral body with concrete, thereby makes that a watt ridge cover plate must use with reinforcing bar.Therefore, the armored concrete slab of making by this watt of ridge cover plate method has complicated structure, and this structure is more complicated more than the common flat armored concrete slab of making by the method for using the cast cover plate.Cast cover plate method has increased employed reinforcing bar and concrete consumption, thereby has increased the construction cost and the weight that has increased concrete slab of made plate.Because concrete slab is very heavy, make the pillar of building be subjected to excessive load, thereby the height that has reduced building makes the number of plies of floor be restricted.Therefore, watt ridge cover plate D has reduced the practicality of building.
When the crest that is necessary to traverse watt ridge cover plate D was settled electric wire or water pipe, cover plate D just must partial cut sever so that admit electric wire or water pipe within it.Otherwise, will make the height of ceiling reduce because electric wire or water pipe are placed in watt outside of ridge cover plate D.In this case, the practicality of building has also reduced.
As illustrated in fig. 1 and 2, watt ridge cover plate method comprises that the steel work that will add is placed in the step on watt ridge cover plate D.In the embodiment shown in fig. 1, vertical steel bundle that at first will form by the mode of using a plurality of hoop steel H that many main reinforcement T are welded together is placed in the passage D1 inboard that is formed by watt each trough of ridge cover plate D.Then, regularly many vertical and horizontal reinforcing bar L and S are placed in steel mesh reinforcement of formation on the tendon.Thereby a plurality of distance piece S1 fix tendon and steel mesh reinforcement tendon and steel mesh reinforcement stably are fixed on their position.
In the embodiment shown in Figure 2, go forward many reinforcing bars are welded and form this steel mesh reinforcement W many main reinforcement T being suspended at a steel mesh reinforcement W.Then, the steel mesh reinforcement W that uses a plurality of distance piece S2 will have main reinforcement T is fixed on watt of ridge cover plate D.
If describe briefly, the advantage of watt ridge cover plate method is the step that it has saved placement and has taken off the cast cover plate.But a watt ridge cover plate method is in-problem, i.e. the construction of its feasible reinforced concrete structure of finally making becomes complicated.In watt ridge cover plate method, reinforcing bar must be compiled by complex steps, and this method is compared with the usual way that uses the cast cover plate to make reinforced concrete structure and be remarkable.
In the effort of the problem that overcomes common watt ridge cover plate method, the inventor had before proposed " a kind of watt ridge cover plate that has watt ridge support beam that is used for armored concrete slab ".
The superincumbent watt ridge cover plate that is used for armored concrete slab, use two opposed lattice parts 2 and 2 ' with three reinforcing bars: upside reinforcing bar 3 and two downside reinforcing bars 4 and 4 ' weld together, thus form a watt of ridge support beam 1, as shown in Figure 3.A plurality of watts of ridge support beams 1 are welded to watt of ridge cover plate 10 of formation on the base plate 11.In order to make an armored concrete slab, go forward a watt ridge cover plate 10 is placed on the beam (not shown) steel mesh reinforcement W being placed in a watt ridge cover plate 10.After steel mesh reinforcement W being placed on watt ridge cover plate 10, be injected on the cover plate concrete and sclerosis a period of time, make a concrete and a watt ridge cover plate 10 integrally form a single armored concrete slab.In this case, base plate 11 forms the surface dressing spare of the final armored concrete slab that is shaped, and makes and can shorten the time of construction and can save the cost of constructing, and makes armored concrete slab simultaneously.Recited above watt of ridge cover plate can also alleviate the weight and the thickness of the concrete slab of finally making.
But top watt ridge cover plate 1 is by with a upside reinforcing bar 3 and two downside reinforcing bars 4 and 4 ' with two lattice spares 2 and 2 ' weld and make, make a watt ridge support beam 1 can waste lamentedly lattice spare 2 and 2 '.In addition, three reinforcing bars 3,4 and 4 ' and two lattice spares 2 and 2 ' must weld become a watt ridge support beam 1, thereby have reduced operating efficiency and increased the cost of construction when making armored concrete slab.
Another problem of above-mentioned watt ridge cover plate is that a watt ridge support beam 1 is formed with the space between two lattice spares.Because concrete is not easy to flow in this space, just is necessary to force concrete to enter in this space, thereby has reduced operating efficiency when making armored concrete slab.
On the ceiling of the armored concrete slab that is necessary to have watt ridge cover plate D or corrugated sheet 10, settle electric wire, when water pipe or air conditioning duct, just must will be used for fixing electric wire, a plurality of support (not shown) of water pipe or conduit are installed on cover plate D or the panel 10 with certain interval location.In this case, the parergon material resemble the ceiling just must use a plurality of cramp bars to be placed on the ceiling of armored concrete slab, so just can cover electric wire, water pipe and conduit.But, do the height that can reduce operating efficiency and reduce every floor layer of building like this, thereby damaged the practicality of this building.
Therefore, the problems referred to above that the present invention will consider is in the prior art to be occurred, its objective is provides a kind of corrugated sheet that is used for armored concrete slab, watt ridge support beam of this panel is to make by such mode, promptly use a single lattice spare that upside and downside reinforcing bar are welded, lattice spare is soldered on the reinforcing bar by a zigzag passage through reinforcing bar, has so just saved lattice spare, simplified welding process, improved operating efficiency and saved construction cost.

Fig. 8,9,10A and 10B show base plate according to other embodiments of the invention.At Fig. 8,9, among each embodiment among the embodiment shown in 10A and the 10B, base plate 21 made have a plurality of staggered ridge peaks 23 and the bellows-shaped of trough 22.One vertically the fixed-site of trimming panel 25 each ridge peak 23 below or removably be attached on the base plate 21, thereby cover by each ridge peak 23 formed passages and form a pipeline 24 that is used to admit electric wire or water pipe N.
Trimming panel 25 can be soldered on the base plate 21, as shown in Figure 9.But, also trimming panel 25 removably can be attached on the base plate 21, shown in Figure 10 A and 10B.In the case, the both sides of the edge with trimming panel 25 are bent to form parquet border 25a and 25b.Simultaneously, base plate 21 mills out groove on the position corresponding to parquet border 25a and 25b, thereby forms dovetail groove 21a and 21b.Each trimming panel 25 removably is attached on the base plate 21 by the wedge shape method of attachment.
In the embodiment shown in Figure 10 A, each parquet border 25a of trimming panel 25 is bent upwards with the acute angle less than 90 °, and simultaneously two dovetail groove 21a are being formed on each trough 22 with the approaching position of the opposite side of trough 22.Therefore, two parquet border 25a of each trimming panel 25 just removably are embedded in the dovetail groove 21a that forms on the opposed trough 22 at each ridge peak 23.In such cases, can reduce the width of each trimming panel 25.Simultaneously, thus at least two dovetail groove 21a must form the quantity that is increased in the dovetail groove 21a that forms on the base plate 21 on each trough 22 of base plate 21.In the embodiment shown in Figure 10 B, each parquet border 25b of trimming panel 25 is bent upwards with the obtuse angle greater than 90 °, longitudinally forms a single dovetail groove 21b simultaneously in each trough 22 in the heart.In such cases, corrugated sheet must comprise the trimming panel 25 of a broad.Simultaneously, can on each trough 22, form a single dovetail groove 21b, thereby reduce the quantity of the dovetail groove 21b of base plate 21.
As described above like that, the mode that each of corrugated sheet watt ridge support beam 1 is to use a lattice spare 2 that upside and downside reinforcing bar 3 and 4 are welded is made.Lattice spare 2 is provided with respect to upside and downside reinforcing bar 3 and 4, has a base section 2b respectively, and the fixing flank 2a of 2b ', 2a ' are provided with on the opposite side of two reinforcing bars 3 and 4 alternately.Therefore, compare with the common watt ridge support beam with two lattice spares, corrugated sheet of the present invention has reduced the quantity of lattice spare 2 effectively, and the intensity of watt ridge support beam 1 that does not reduce to make.Because upside and downside reinforcing bar 3 and 4 use a lattice spare 2 integrally to form a watt of ridge support beam, the quantity of the pad between lattice spare 2 and reinforcing bar 3 and 4 just can reduce effectively, thereby has improved operating efficiency and reduced cost of production.
In corrugated sheet of the present invention, the single lattice spare 2 of watt ridge support beam 1 supports with common watt ridge that beam is different can't to stay the space, therefore concrete can flow through a watt ridge support beam 1 at an easy rate, thereby has improved operating efficiency when using corrugated sheet to make armored concrete slab.
The longitudinal strength of corrugated sheet 10 is provided by a watt ridge support beam 1, and bearing the transverse strength of panel 10 of weight concrete and the local strength of panel 10 is then provided by base plate 11.In corrugated sheet 10 of the present invention, the ridge peak 12 with lug boss 13 has reduced the stress that caused by the load that is applied on the corrugated sheet 10 effectively, thereby corrugated sheet 10 can bear this load effectively.Therefore, the vertical and horizontal intensity of corrugated sheet 10 of the present invention all is improved.
At Fig. 8,9, among each embodiment shown in 10A and the 10B, base plate 21 forms has a plurality of staggered ridge peaks 23 and the corrugated of trough 22.In addition, vertically rebuild panel 25 and be attached on the base plate 21, thereby cover the passage that forms by each ridge peak 23 and form a pipeline 24 that is used to admit electric wire or water pipe N in the position of each ridge peak 23 downside.
Therefore, as Fig. 8,9, the corrugated sheet shown in 10A and the 10B is easy to pack into electric wire or water pipe N in pipeline 24, so just need not the common support that is used for fixing electric wire or water pipe N.Above-mentioned each corrugated sheet with such pipeline 24 so just can improve the outward appearance of ceiling and the thickness that need not use ceiling panel and reduce made concrete slab effectively, and do not reduce its intensity, but also improved the practicality of building.
In the time shown in Fig. 8 and 9, will rebuilding panel 25 and be fixed on the base plate 21 by a kind of spot welding or screw-jointing method like that, be very difficult to change the passage of dress electric wire or dress water pipe.For the problem that in fixing trimming panel 25, is run into above overcoming, shown in Figure 10 A and 10B, rebuild panel 25 like that and can removably be attached to base plate 21.That is to say, the both sides of the edge of trimming panel 25 can be crooked forming parquet border 25a, 25b, simultaneously on the base plate 21 corresponding to parquet border 25a, cutting on the position of 25b so just forms dovetail groove 21a, 21b.In such cases, trimming panel 25 can be by will rebuilding the dovetail groove 21a of panel 25 usefulness itself and base plate 21, and the mode that the parquet border 25a of the panel 25 of 21b aligning, 25b are placed on the passage at each ridge peak 23 removably is attached on the base plate 21.Then, will rebuild on the panel 25 and push away, thereby make edge 25a, 25b is mounted to groove 21a vertically, in the 21b.Another kind method is, thereby trimming panel 25 can be longitudinally with edge 25a by be placed in base plate 21 1 sides before longitudinally promoting panels 25 with respect to base plate 21, and 25b is mounted in the groove 21a 21b.In the embodiment shown in Figure 10 A and the 10B, because trimming panel 25 is removably to mesh with respect to base plate 21, so heavy connection of pipe can change at an easy rate, thereby improved operating efficiency in dress electric wire or dress water pipe.
As described above such, the invention provides a kind of improved corrugated sheet that is used for armored concrete slab.This corrugated sheet has a watt of ridge support beam, and this support beam is by upside and downside reinforcing bar are formed with the mode that lattice spare welds.Therefore, compare with common watt of ridge support beam with two lattice spares, corrugated sheet of the present invention can reduce the quantity of lattice spare effectively and can not reduce the intensity that made watt ridge supports beam.In addition, the quantity of the pad between lattice spare and upside and the downside reinforcing bar also can reduce effectively, thereby has improved operating efficiency and reduced cost of production.
The intensity of corrugated sheet of the present invention improves because of open and flat ridge peak has been arranged, this open and flat ridge peak be on base plate, form and be provided with a plurality of protuberances.Therefore, this corrugated sheet can reduce the stress that caused by load and bearing load effectively effectively.In another embodiment, the base plate of corrugated sheet forms and has a plurality of staggered ridge peaks and the bellows-shaped of trough.In this case, rebuilding panel longitudinally can cover the passage that is formed by each ridge peak and form a pipeline that is used to adorn electric wire and dress water pipe.Corrugated sheet with this pipeline can improve the outward appearance of ceiling effectively and need not to use common ceiling panel and can reduce the thickness of made concrete slab and can not reduce the intensity of concrete slab, has also improved the practicality of building.
