The specific embodiment
To carry out sets forth in detail to the present invention at this, and be illustrated with accompanying drawing.Reference number wherein is presented at the same part in several different views.
Builing industry has had good identification and employing for the technology of producing the AAC wall.Strong concrete also has been widely used in bridge and the high building structure.The usually not enough intensity of low-density AAC and can't be applied to load bearing wall.
The present invention use fleece in CWS to strengthen structural strength.As doing the drag analysis by clock context and other people paper " fiber is in the stability of composite material " in January, 1969.Simultaneously also use strong concrete to strengthen the intensity of AAC member.Because its strength-enhanced, wall can be built but not current general solid brick with hollow wall coil.The weight of member also is minimized so that easily install.
Fibroreticulate material in the AAC member can be alkali-resisting glass fiber, antirust iron wire, nylon fiber or other suitable fiber.The big I of each direction twine is determined by the requirement of strength of purposes.The fiber size of load direction is by compression load amount decision, considers the bubble in the concrete and the fiber of vertical axis simultaneously, influences its stability.In general arrangement, shrinkage requires also to need to take in.Fleece can be that individual layer also can be a multilayer.
Fiberglass mesh has been used to the external surface of cement wall plate, mainly is in order to protect the surface but not the purpose in order to carry.See and authorize Gregg and other people U.S. Patent number 6,787,486, " the pre-cast panel that comprises the foam concrete core ", at this as a reference.Authorize CREAMER and other people patent No. 6,773,500 " fiber is strengthened foam concrete and preparation method " in August, 2004, at this with for referencial use.And the fiber that other places are mentioned helps to shrink and break.They are not used in bearing load.At the U.S. Patent number 6,532,710 of authorizing Terry " the unit concrete is prevented hot system ", as a reference at this.It is different with the present invention.
Fig. 1-9 expression, foam concrete wall CWS comprises 41, one location-plates 42 of an iron plate rail, 32,33,34,35,36,37 and architraves 31 of many wall coils.The iron plate rail is fixed on the concrete floor.
Shown in Fig. 1,2,3 and 5, wall coil 32,33,34,35,36,37 lower ends are fixed in iron plate rail 41 with concrete screw 46 and are led by location-plate 42 in the upper end.The straightness accuracy that arrange the upper end of wall coil 32,33,34,35,36,37 is by location-plate 42 locator qualifications at wall coil 32,33,34,35,36,37 tops.Location-plate 42 at wall coil 32,33,34,35,36,37 tops has four effects at least: 1) location-plate 42 provides the rigidity of wall along the wall direction, and guarantees the flatness of wall; 2) location-plate 42 covers the wall way that vertical reinforcement and placing of concrete wherein are not set; 3) location-plate 42 increases the intensity of architrave 31; 4) location-plate 42 guiding wall coils 32,33,34,35,36,37 and architrave plate be connected diagonal brace in the appropriate location.
General brick cavity wall does not need the hole of concrete perfusion to cover with iron plate or plastic cement sieve usually, and it does not increase wall intensity.
The present invention welds iron bar 48 and makes location-plate 42 in the both sides of the iron plate post (METAL STUD) of general market use.Iron bar 48 is inserted into downwards in the wall way, extends up to the architrave plate to guarantee the integrality of wall coil and architrave.Location-plate 42 agrees with wall way, is positioned on the wall coil wall and can need other attachment.In case the concrete 47 of pouring architrave 31 and wall way, location-plate 42 just becomes a component parts of architrave 31.
Every wall coil comprises the AAC that uses fibre web 38.As Fig. 4 and shown in Figure 7, convex-concave 61,62 is all done so that interconnect in every wall coil both sides.
As Fig. 8 and shown in Figure 9, two blocks of fiber web plates, 81,82 the templates of architrave both sides as architrave, and become the part of architrave.The bottom of these two blocks of fiber web plates 81,82 is fixed on location-plate 42 with screw 49, and is supported by metal pull bar 71 and stop sleeve 72 on the top of architrave 31.
As shown in Figure 6, at the bottom of wall, iron plate rail 41 is put on the floor, keeps level with following cement paste.Iron plate rail 41 also is fixed on the concrete slab with concrete screw 46, exact position when guaranteeing to construct and its stability.Wall coil is fixed in the iron plate rail, on two blocks of architrave plates are tied up iron bar at location-plate in the bottom then, is supported by metal pull bar and stop sleeve at the top.Wall coil and architrave plate only need be supported on the concrete floor with diagonal brace on one side, to reach vertical and stable position fully.Compare with general brick cavity wall, it has the rapidity of construction, not only every wall coil covers about 5 times of every brick cavity wall area, and the seam that the installation of every wall coil needn't resemble every brick cavity wall must be regulated its straight line and up rightness individually with cement paste.This wall is all faster than any other existing wall with manual installation.
At present, the architrave of brick cavity wall is usually with the concrete beam of template perfusion or put U type pre-cast concrete beam on the wall and penetration concrete.This building method is time-consuming expensive again.
As shown in Figure 2, architrave use two blocks of fiber web plates 81,82 as architrave template.Concrete pouring is between fiber web plate 81,82 and form an architrave.The fiber web plate can be produced with extruder very economical ground, and very fast installation.For example, general housing building, use one 1 " thick 16 " * 12 ' the fiber web plate, 47 pounds of weight, two people or a simple crane just can lift.In Fig. 8, fiber web plate 81,82 is screwed on the location-plate 42 with screw 49 in the bottom.At the top, support by metal pull bar and stop sleeve.Metal pull bar bears the pressure of concrete grout and the top reinforcing bar 44 in the support architrave.End reinforcing bar 43 in the architrave can be suspended from top reinforcing bar 44.This is another advantage than brick cavity wall architrave.Because of the latter, reinforcing bar adheres to usually nowhere, thereby causes the out of position of reinforcing bar so that reduce its intensity.Stop sleeve is to be used for keeping the fiber web plate to be in correct space when metal pull bar during by tie up.The packing ring 73,74 of fiber web plate outside guarantees when pouring concrete the foamed fibre web plate is had pressure distribution preferably.After the concrete casting, stop sleeve stays in architrave.After the concrete setting, metal pull bar and packing ring can re-use.
The fibre web 38,83 of doing fiber web plate and wall coil comprises alkali-resisting glass fiber, antirust wire gauze, perhaps nylon fiber net.Fibre web 38,83 can be with the also available multilayer of individual layer.
Vertical reinforcement 45 and reinforcement foundation and architrave reinforcing bar 43,44 interconnect.
Location-plate increases the bonding strength between wall coil, and covers the wall coil that vertical reinforcement and placing of concrete wherein are not set.Location-plate increases the intensity of architrave, simultaneously can be before pouring concrete, and guiding wall coil and architrave plate are in the tram.In order to improve the bonding strength of whole concrete wall and ground, pour into ordinary concrete 57 in the wall coil that can in position locate, so that ground and architrave link together.
In Figure 10, two stiffening ribs 90 (STIFFENERS) vertically are placed on two blocks of AAC fiber web plates of many wall coils being guided by location-plate 42 and architrave.An angle bar 91 is fixed in the floor.This angle bar 91 that diagonal brace is connected in the bottom then is connected in stiffening rib 90 at the top.The correct verticality of wall coil can probably be adjusted by the adjustment hole 94 on the angle bar 93 that is fixed on the concrete floor, and accurately adjusts with the screw 92 in the middle of the diagonal brace.
Bonded to each other between the adjacent wall coil.
Clearly, AAC density is high more, and its mechanical strength is also high more.For example, the present invention uses the AAC of every cubic chi of density 35 pound weights, adds the twin shaft fibre web and uses strong concrete, can make higher compression power and warp resistance power.The intensity of its increase can be made hollow but not solid.Multistory building also can use this wall.For example, traditional house of high eight chis of wall, the roof architrave is high by 16 ", 8 cun of its Guan Gaowei 6 chis.8 " * 8 " * 6 ' 8 that wall coil wall thickness is 1 cun heavy 49 pounds " hollow wall coil can carry below by two people, another people aims on the wall, can install at an easy rate.
As Fig. 4 and shown in Figure 7, with the concave- convex type 61,62 on wall coil limit with the compactness that guarantees them and the rapidity of construction.The linearity that wall is arranged is further guaranteed by the location-plate on wall coil top.Use adhesive in seam to increase bonding strength and waterproof.AAC architrave plate is positioned on the wall coil top, by the location-plate guiding, guarantees the verticality of wall with diagonal brace.
The present invention brings very big influence can for current builing industry.
Wall coil can be used the method for template and pouring foam concrete, or carries out large-scale production with the extruder method.Provide the wall coil limit concave-convex type in case rapidly be connected to each other accurately.So wall coil itself gently can easily be installed.Such as, smallpox plate hight be 8 ' dwelling house building architrave high by 16 ", manage high by 6 ' 8 "." fiber web plate and AAC pipe can be moved and be installed by two people to weigh 49 pounds of wall coil wall thickness 1.Compare one 6 " * 8 " * 16 " 35 pounds hollow brick, laying bricks on the other hand, and another assistant prepare cement paste the existing centuries of this form of construction work history and never improve.An AAC pipe is two people equally, with the hands just can cover five times wall area easily.The cost of wall coil is unlike general brick cavity wall height.Because the bubble of the inside and adopt the method for automatic extruder to carry out large-scale production, material have almost been expanded 5 times and reduce cost of production on volume.Therefore, this product can be competed with general hollow brick.The thickness of wall coil can be from 4 " to 24 ", and the wall coil shell wall thickness can be from 3/4 " to 4 " according to load requirement.The fleece size and the number of plies also are to decide according to the load needs.Need according to load, the wall base and architrave interconnect with vertical reinforcement and perfusion ordinary concrete, to guarantee the integrality of wall.Cut off the new joint that needs with the cooperation wall because of wall coil.As shown in Figure 7, the concavo-convex moulding on wall coil limit can coincide.This wall can be used on tier building.Being noted that here this wall uses the iron plate rail in the bottom of wall coil, using location-plate at the top, is the simple and easy and economical production for wall coil.
The verticality of wall and stability are guaranteed by supported on both sides in construction usually.The support of general wall was both very time-consuming, also was difficult to settle accurately.Multistory building also is difficult to support and is placed on the outside.
The present invention only is supported on wall on the concrete floor on one side, two stiffening ribs by vertical placement with cover on by the wall coil that location-plate led and the architrave plate of both sides on, they are connected together.Wall is connected on the angle bar that is fixed on the concrete floor by bearing diagonal then.The Position Approximate of wall is adjusted by the adjustment hole of this angle bar.Wall verticality is accurately accurately regulated with the screw in the middle of the diagonal brace.
The present invention also comprises the method that foam concrete wall (CWS) is installed, and this method has comprised the step of fixed iron piece rail in ground, and fixing most wall coils are in iron plate rail and the step that guides most wall coils with location-plate.Every wall coil comprises the AAC that uses fibre web.Convex-concave and wall coil concrete perfusion are all done to bear load-carrying and ground to be connected to the step of top architrave in every wall coil both sides.The construction party rule of architrave supports this fiber web plate with both sides and top that two blocks of fiber web plates are connected in location-plate with metal pull bar and stop sleeve.This method is included in the step of placing of concrete between two blocks of fiber web plates of architrave.
This method has more comprised AAC wall coil and the iron plate rail step of connecting that majority is contained the alkali resistant fiberglass mesh.
Obviously, those people that are good at this technology are not breaking away under scope of invention and the spirit, can carry out many-sided correction to foam concrete wall of the present invention (CWS).Original idea of the present invention comprises various corrections and the change in foam concrete wall (CWS) the accessory claim scope.
