Description

Quick concrete blinding prefabricated section

For a long time; in industry and civilian construction structure construction procedure; the concrete structure column engineering; often utilize normal wood molding or iron plate mould to protect the section bar material; from formwork, concrete perfusion being installed to the form removal process, working procedure is many, and the cycle is long; not only need wide variety of materials and manually but also be difficult to guarantee workmanship, caused the waste of fund and engineering time.

The purpose of this utility model is to provide a kind of concrete structure column formwork of can being used as to use, but the quick concrete blinding prefabricated section of the part material of main part of this post of double as again.

The quick concrete blinding prefabricated section of the utility model is a kind of prefabricated cement components of integral vertical type that is made of difform frame, its cross section can be right angle type or concave shape or circular arc or square frame shape, the connection groove is left in the upper surface of its each side of frame, the lower surface has convex to be connected and fixed piece, be positioned on the ipsilateral, the connection groove of lower surface and convex are connected and fixed the piece center on same axis, its cross section is isosceles trapezoid, trapezoidal top margin (minor face) is in the template outside, in the template inboard, the vertical inspection line that cross section is an isosceles triangle is all left in the outside of each side of frame on trapezoidal base (long limit).

The utility model it " concrete blinding prefabricated section fast " is a kind of cement prefabricated component, except that can making the concrete structure column formwork, also has following characteristics:

1, can check the vertical and plane degree of accuracy of cylinder formwork intuitively and accurately, the quality that has guaranteed to wait to build post and metope.The quick concrete blinding prefabricated section of the utility model utilizes the annexation of tongue and groove, guarantee the vertical and fastness of connection of formwork, every block connects one, all can directly check the verticality and the flatness of formwork from two aspects, the compactness of casting, verticality and the plane degree of accuracy have been guaranteed when the placing of concrete pillar.

2, save material, easy to use, high efficiency, overall economic efficiency be good.

The quick concrete blinding prefabricated section of the utility model not only can be used as the main column formwork, also can be used as the some of main column, the material that takies that needn't need other templates, iron nail, iron wire or the like, also needn't dismantle template, thereby saved material and recruitment time widely, reduced constructing operation operation and difficulty, improved operating efficiency, overall economic efficiency is good.

3, make simply easy construction.The quick concrete blinding prefabricated section of the utility model is a primary raw material with cement and middle sand and melon seeds sheet, and pouring in the model of a sealing, prefabricated the forming of vibration are made quick and easy.

Below, with embodiment the architectural feature of the quick concrete blinding prefabricated section of the utility model is further described in conjunction with the accompanying drawings.

Embodiment one

A kind of quick concrete blinding prefabricated section of doing interior outside corner of wall constructional column formwork that is suitable for.Its structure such as Fig. 1, Fig. 2, shown in Figure 3, this prefabricated section system is by cement, the melon seeds sheet, the frame cross section that middle sand is made is the three-dimensional cement components of right angle type, each side of frame is the square bodily form, the long 400mm of square, wide (height) 360mm, thick 30mm, the upper surface of each side of frame is left and is connected groove 1, its cross section is trapezoidal, be of a size of: top margin (outside) * base (inner edge) * height=80mm * 100mm * 30mm, the dark 50mm of groove, it is that the convex of isosceles trapezoid is connected and fixed piece 2 that there is cross section the lower surface, its cross sectional dimensions: top margin (outside) * base (inner edge) * height=70mm * 90mm * 30mm, the high 40mm of convex piece, the connection groove of upper surface and the convex that is positioned at the lower surface are connected and fixed the piece center on same axis, and at every frame lateral surface of prefabricated section cross section being arranged is that the flute profile of isosceles triangle is vertically checked line 3.The tolerance fit that connection groove and convex are connected and fixed between the piece is 10mm, during use, convex is connected and fixed piece inserts in the connection groove, puts a little cement mortar of people again and gets final product.

A kind of conversion as present embodiment, the length and width size of its frame can strengthen, dwindle, correspondingly its thickness can strengthen or dwindle, and the scope of thickness is between 20-50mm, but also respective change of the size that the connection groove of its each side and convex are connected and fixed piece.

Embodiment two

As the quick concrete blinding prefabricated section of concave shape of independent square square column formwork, its structure is referring to Fig. 4, Fig. 5, Fig. 6.This prefabricated section frame cross section is a concave shape, lays respectively at the connection groove 1 of each upper and lower end face in side of frame and size that convex is connected and fixed piece 2 and the shape that is positioned at the inspection line 3 on three sides of concave shape, and size is with embodiment one.

Embodiment three

Quick concrete blinding prefabricated section as circular insulated column formwork, its structure is referring to Fig. 7, Fig. 8, Fig. 9, the cross section of this prefabricated section frame is semicircle, and the connection groove 1 and the convex that lay respectively at upper and lower end face are connected and fixed piece 2 and the shape that is positioned at the inspection line 3 on the semicircle lateral surface, big or small with embodiment one.
