Abstract
The utility model discloses a supporting die for concrete external wall window hole, which is characterized by comprising steel plates; the rectangular window hole supporting die is formed by surrounding of the steel plates; angle irons are arranged on the inner side surfaces at four corners of the rectangular window hole supporting die and are fixed in sequence by bolt groups; a supporting steel pipe group is fixed at the inner side of the rectangular window hole supporting die; a layer of moldboard strips are added on the surface contacted between the left and right sides of the rectangular window hole supporting die or the surface contacted between the periphery of the rectangular window hole supporting die and concrete; the moldboard strips are fixed on the steel plates of the rectangular window hole supporting die; the bolt groups comprises three bolts; and the moldboard strips are PVC (polyvinye chloride) plate strips which are fixed on the steel plates through countersunk screws. The supporting die for the concrete external wall window hole has the advantages that the supporting die system has large rigidity, is difficult to deform, has long service life, frequent turnover, high strength of parts, and good durability; doors and windows can be directly mounted in grooves reserved surrounding the formed concrete holes; and the economical benefic and the social benefic are both obvious.
Description
Technical field
The utility model relates to the formwork field, relates in particular to a kind of concrete exterior wall window opening formwork.
Background technology
Traditional concrete exterior wall window opening formwork, formwork rigidity is little, easy deformation, door and window pack into concrete on; Need plaster, the seam imprecision of window and window opening mouth, comes off, has the crack at gaul again, has increased cost, speed of application is slow; Steel form is not long application life, and the number of turnover is few, and strength of parts is low; A little less than the durability, the concrete structure size of moulding is inaccurate, and economic benefit and social benefit are also not obvious.Therefore, be badly in need of a kind of improved technology and solve existing this problem in the prior art.
Summary of the invention
The purpose of the utility model provides a kind of concrete exterior wall window opening formwork.
The technical scheme that the utility model adopts is:
A kind of concrete exterior wall window opening formwork; Comprise steel plate, said steel plate surrounds rectangle window opening formwork, and four jiaos of medial surfaces of rectangle window opening formwork are provided with angle bar; Fixing successively between the said angle bar through the bolt group; Rectangle window opening formwork inboard is fixed with the supporting steel pipe group, adds one deck template bar around the rectangle window opening formwork left and right sides or the rectangle window opening formwork with on the face that concrete contact, and said template bar is fixed on the steel plate of rectangle window opening formwork.
Said bolt group comprises three bolts.
Said template bar is the PVC lath, and said PVC lath is fixed on the steel plate through dormant bolt.
The utility model has the advantages that: this formwork system rigidity is big, is not easy distortion, long service life, and the number of turnover is many; Strength of parts is high, good endurance, and the groove that stays around the concrete hole after the moulding, door and window can directly be contained in the groove; Beat foamed glue in the groove, Puttying all around need not be plastered again; Not only can make the seam of window and window opening mouth tight, and can prevent gaul, come off, crack, minimizing cost, accelerate speed of application, economic benefit and social benefit are obvious.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the sectional view of the utility model A-A.
Fig. 3 is the figure that derives of the utility model A-A.
Wherein: 1, steel plate, 2, angle bar, 3, the PVC lath, 4, dormant bolt, 5, the bolt group, 6, steel pipe.
The specific embodiment
Shown in Fig. 1-3, a kind of concrete exterior wall window opening formwork of the utility model comprises steel plate 1, and said steel plate 1 surrounds rectangle window opening formwork; Four jiaos of medial surfaces of rectangle window opening formwork are provided with angle bar 2, and fixing successively through bolt group 5 between the said angle bar 2, rectangle window opening formwork inboard is fixed with supporting steel pipe group 6, add one deck template bar around the rectangle window opening formwork left and right sides or the rectangle window opening formwork with on the face that concrete contact; Said template bar is fixed on the steel plate 1 of rectangle window opening formwork, and said bolt group 5 comprises three bolts, and said template bar is a PVC lath 3; Said PVC lath 3 is fixed on the steel plate through dormant bolt 4, and this formwork system rigidity is big, is not easy distortion; Long service life, the number of turnover is many, and strength of parts is high; The groove that stays around the good endurance, the concrete hole after the moulding, door and window can directly be contained in the groove; Beat foamed glue in the groove, Puttying all around need not be plastered again; Not only can make the seam of window and window opening mouth tight, and can prevent gaul, come off, crack, minimizing cost, accelerate speed of application, economic benefit and social benefit are obvious.
Preparation method:
Door and window hole inside casing mould adopts 3-6mm steel plate 1, leans against angle bar 2, two angle bar 2 intersections and uses φ 8-12 bolt group 5 fixing; Bolt group 5 quantity of every end are three; Can guarantee to dare steel plate 1 rigidity, not yielding, can be according to original metope split bolt group 5 spacings construction; And can guarantee that PVC lath 3 roots do not run mould, the inside casing mould is made diagonal brace with the steel pipe 6 of φ 40-50;
Around the rectangle window opening formwork left and right sides or rectangle window opening formwork with on the face that concrete contact, add the PVC lath 3 that one deck 10-15mm is thick, 50-100mm is wide; Make PVC lath 3 rats, the concrete surface after the moulding stays groove, groove width be equal to doorframe and window frame thickness; Window will directly can be installed in groove location; Dismiss infusion in the groove, Puttying all around, thus stopped gaul, defective such as ftracture, come off;
Moulding according to design and construction drawing door and window hole limit is made typing setting to PVC lath 3;
Be convenient to door and window hole window sill sluicing up and down simultaneously, do not cause seeping phenomenon, can be 3-6mm steel plate 1 through machine-shaping.
