The application is the part continuation application of the U.S. Patent application 09/609,189 on June 30th, 2000, and applies for that 09/609,189 is again the part continuation application of the U.S. Patent application 09/389,607 on September 3rd, 1999.

Technical field

Present invention relates in general to a kind of structural system (building system) of concrete form wall of insulation, and it is particularly related to a kind of formwork that has extended pattern (expanded) polystyrene sidewall, wherein form passage between the two side, mushy concrete injects wherein, thereby forms the part of permanent wall body structure.

Background technology

The use of concrete heat-insulating form wall structural system has had good decades, can avoid using metal or wooden formwork when constructing the building concrete body of wall at the scene with this method.Although adopting metal or wooden formwork is a kind of method of reliable making wall body structure, but using, this method also has shortcoming, be that this formwork heaviness is difficult to use, and fully harden and also these formworks must be dismantled behind the form removal at concrete, so they can not form the part of wall body structure.This behavior need expend a large amount of labours, particularly needs a large amount of labours to fix formwork and to concrete spouting at building-site.

Now, the wall structure system of competitive concrete heat-insulating formwork all adopts the extended pattern polystyrene material, and to be divided into two basic classifications be piece type and sheet type.Piece type system adopts molded extended pattern polystyrene building block system, and its form with building block is carried out stacked to form concrete wall.Piece type system uses very easy but requires a large amount of on-the-spot labours to assemble.These pieces all have Internal jigging or support usually, and structurally it is used for being connected between boss and the piece.A major defect of piece type system is the opening of bad formation window or door, thereby has limited their application, and it is mainly used in independent walling system or the single structure as garage etc.American documentation literature US5 discloses a kind of type system in 465,542, is different from common block system, and it preferably has a kind of embedded attachment flaps and fixes wall covering.

Sheet type system then adopts two molded extended pattern polystyrene sheets, and respectively there is a slice the both sides of formwork.Polystyrene sheet is separated by anchor clamps or mounting system usually, and these work all need to finish in the working site, very heavy and labor intensive.Now designed the whole bag of tricks the connection between the sheet type system has been sealed, but the same labor intensive of these methods.Do not have a kind of type system can place window or door at an easy rate now, they need expend a large amount of on-the-spot labours equally.In addition, these two kinds of competitive systems also have another major defect, and they can't support concrete and prevent that concrete from passing formwork when perfusion promptly not have additional support (outside formwork or pillar).American documentation literature US3 discloses a kind of type system in 788,020, and it comprises a pair of panelling that separate, that connected by the fire-type tensional element in one embodiment.

Although competitive concrete heat-insulating formwork has many shortcomings, because they can be for building structure brings energy-conservation and comfortable advantage, so their also widely uses in industry.Only energy-conservation this advantage just makes this competitive system be sold and use.Also have building acts also to require on basement and basic body of wall, to adopt heat preservation technology.Therefore, although concrete heat-insulating formwork system can not save the labour with respect to traditional building method, they are accepted to be used for the system on building basement and basis more and more by people.Yet contractor and developer are but very limited to their acceptance level.

The invention provides a kind of concrete heat-insulating formwork structural system that can significantly reduce on-the-spot labour, and a kind of system that is easy to arrange window and door is provided.

Summary of the invention

The first embodiment of the present invention provides a kind of concrete form wall structural system of insulation, it has the extended pattern polystyrene sidewall of lengthening spaced apart from each other, each sidewall all has interior surface opposing, and this inner surface is formed by the rib that is arranged vertically and longitudinally separate, the end of this rib is the plane substantially, and is adjacent one another are to be used as the concrete wall formwork.

These ribs that separate form passage, are used to hold the concrete that is poured in wherein.The polystyrene sidewall preferably is cut into two parts that equate substantially by a slice extended pattern polystyrene and forms.Thereby the upper and lower end face that last bottom had of the rib on the sidewall separates forming between the sidewall with the limit of sidewall preferably that concrete receives the district and following concrete receives the district, and concrete receives to distinguish and is connected with the intercostal passage up and down.In order to form window and gateway, the rib of sidewall has the interrupt unit of positioned opposite to hold the separation pad (spacer) that is arranged between the sidewall, and these separation pads all adopt the required window or the shape of gateway.

Second embodiment of the invention provides a kind of concrete form wall structural system of insulation, it has the extended pattern polystyrene sidewall of lengthening spaced apart from each other, has separator (divider) between the sidewall simultaneously, each separator all comprises end face, bottom surface and two flat sides, one of them side links to each other with a sidewall, and another side links to each other with second sidewall.Separator is longitudinally-spaced along sidewall, thereby forms passage between separator.Thereby going up of separator end face and bottom surface and sidewall following spaced apartly forms between sidewall up and down that concrete receives the district, and concrete receives that passage is connected between district and the separator up and down.In order to form window and gateway, be connected in the first side wall after the separator cutting, so just can form the pedestal (seat) of required window or gateway shape.One separation pad is inserted in the pedestal and connected second sidewall in.

The 3rd embodiment of the present invention provides a kind of wall structure system of concrete blinding of insulation, and it comprises one with the molded formwork of single-piece form, and somewhat a similar structure of the structure with first and second embodiment can be provided after it assembles.Yet from the viewpoint that this formwork need not be assembled, present embodiment more can be saved the labour.

One plastic septum (barrier) can be laminated on the external surface of one or two sidewall of the present invention, so neither need last one coat, the dividing plate of blocks moisture, anti-erosion, insect protected need be provided yet.When formwork was used for ground, this point was particularly useful.This plastic septum preferably adopts thickness to be about 1/16 " the ABS plastic sheet.

The specific embodiment

The invention provides a kind of improved concrete heat-insulating form wall structural system, it can be applied in the construction industry so that ground, basement and the ground concrete body of wall with insulation effect to be provided better as a kind of method fast and effectively, can avoid simultaneously on-the-spot a large amount of labours of input, the time that significantly reduces on-the-spot structure and finish.System of the present invention also has diversity more widely with respect to existing concrete heat-insulating formwork system based on piece or sheet, it is applicable on the ground, underground and multistory building inside and outside.

Referring now to Fig. 1,, Figure 1 shows that first embodiment of concrete heat-insulating form wall structural system, it is represented with 10 on the whole.System shown in those of ordinary skills know only is a section of whole system, and except those parts had the part of window, the structure of each section was all identical.System 10 provides a formwork, its place a standard base base 11 above, comprise the extended

pattern polystyrene sidewall

12 and 13 of a pair of elongation.Base portion in each

sidewall

12 and 13 all has angle steel arranged apart 14 to be fixed on the base 11, thereby sidewall is fixed with respect to base 11.

As Fig. 2 and 3 findings, show the sidewall 16 of the sidewall 12 shown in can be used as or 13, sidewall 16 has an external surface 17 (only pointing out at Fig. 3) and an inner surface 18, and inner surface 18 has the rib 19 that is arranged vertically and separates along its length, and rib 19 is outwards outstanding from inner surface 18.As shown in Figure 2, rib 19 has upper and lower end face 20 and 21, and its

bottom

22 and 23 of going up with respect to sidewall 16 is separated out respectively.Preferably referring to Fig. 3, every root 19 is formed by three sides at least, thereby the sidepiece 24 of two inclinations ends at outer surface 25 and form passage 26 between rib 19, rib 19 is being the mirror image symmetry in shape, sidewall 16 can be formed with a heated filament cutting by a slice extended pattern polystyrene like this, so also can improve the intensity of system 10.The side 27 and 28 of sidewall 16 is preferably made and can be interconnected with adjacent wall 16.Side 27 comprises a narrower crossette part 29, and side 28 comprises the recess 30 that a size and crossette 29 equate substantially.In addition, the external surface 17 of sidewall preferably includes lathing 31 a plurality of vertical arrangements, that separate, indent, it can be used to intact man-hour ornament materials is fixed on the sidewall 16 at the concrete wall structure of insulation.

Referring now to Fig. 4,,

sidewall

12 and 13 is relative positioning each other, and the plane 25 of rib 19 is adjoined each other to be used as the spacer body between the sidewall like this.In this case, the passage between the rib 19 26 can form one and be used for receiving concrete hexagon cavity.When this shape is added on

sidewall

12 and 13 at pressure, because the width at spacer body middle part is less thereby can reduce the decrement of rib 19.In addition, as shown in Figure 5, concrete receives district 32 and 33 because the upper surface 20 of rib and lower surface 21 with respect to following 22 and 23 distances separately respectively that go up of sidewall, therefore form up and down respectively, and they are connected with passage 26 between the rib 19.

In order to strengthen formwork system 10 formed wall body structures, can reinforcing rod be fixed on (Fig. 4,6 and 7) in the passage 26 by the snap formula reinforcing bar centralizer 36 shown in Fig. 8,9,10.Anchor clamps 36 are rectangle and thinner, and the wherein anxious part 37 of removing has two fins 38, is used for fixing reinforcing bar 35, as shown in Figure 9.Anchor clamps 36 are preferably made by semirigid plastic, and it is flexible inserts reinforcing bar 35 wherein, but its intensity is enough to reinforcing bar is remained on center suitable in the passage 26.By anchor clamps 36, reinforcing bar can fast and effeciently be fixed on the appropriate position of passage 26.
