Abstract

The utility model discloses combined type U-groove section bar of a building aluminum alloy formwork. The combined type U-groove section bar mainly comprises two L-shaped main bodies with the same width or different widths and three ridge reinforced concave type ribs. The upper ends of the L-shaped main bodies are right-angle edges, one ends of the right-angle edges are thickened to be L-shaped edges, the other ends of the right-angle edges are half dovetailed small protrusions, dovetailed small protrusions are arranged in the middle of the lower ends of the L-shaped main bodies, the two L-shaped main bodies with the same width or different widths are closely inlaid and combined with the three ridge reinforced concave type ribs together to form a set of complete U-groove section bar, and the L-shaped main bodies and the ridge reinforced concave type ribs are respectively formed in one-shot through molds. The two L-shaped main bodies and the three ridge reinforced concave type ribs are combined to form the complete U-groove section bar, therefore molding and machining difficulty of the L-shaped main bodies and the ridge reinforced concave type ribs is reduced greatly, production efficiency can be doubled, and meanwhile used materials are reduced. The L-shaped main bodies in different width can be combined to form the U-groove section bar different in width, and therefore demands of walls different in width can be met. The L-shaped main bodies and the ridge reinforced concave type ribs are respectively formed in one-shot through the molds, and therefore the designed combined U-groove section bar is practical, simple in structure, firm and reliable and saving in labor and material.

Description

A kind of U channel section of sectional construction aluminium alloys template

Technical field:

The utility model relates to a kind of U channel section of sectional construction metal form, is specifically related to a kind of U channel section of sectional construction aluminium alloys template.

Technical background:

Construction formwork is the important procedure of concrete structure engineering construction, in the cast-in-place concrete structure engineering, form work engineering generally accounts for 20%～30% of concrete structure engineering cost, account for 30%～40% of the engineering amount of labour used, account for about 50% of the duration, mould plate technique directly influences quality, cost and the benefit of engineering construction.

Because the aluminum alloy building template number of turnover of U channel section combination is many, at the bottom of work efficiency height, quality better, the integrated cost, the renewable repeated use of material, and large tracts of land is used.But substantially all be one-shot forming by the U channel section in the market, cause difficulty of processing big, at the bottom of the production efficiency, cause material usage to increase.Because the difference of construction wall structure on width in the construction formwork difference of the requirement of engineering of constructing, needs to use the U channel section of more specifications, caused cost and the difficulty of construction simultaneously.

The utility model content:

In order to solve the deficiency that above-mentioned U channel section exists, the utility model provides a kind of U channel section of novel combination type building aluminium alloys template, it is the new technical scheme that proposes on the basis of existing U channel section, compared with prior art, its U channel section material is strengthened matrix muscle (2) by the L type main body (1) of 2 differences or same widths and 3 ridges respectively and is inlayed and combine, and L type main body (1) and ridge reinforcement matrix muscle (2) are respectively by mould disposal molding separately.Its technical scheme is as follows:

A kind of U channel section of sectional construction aluminium alloys template is strengthened matrix muscle (2) by the L type main body (1) of 2 different in width or same widths and 3 ridges and is combined into the complete U channel section of a cover.This L type main body (1) upper end is right-angle side, be that the inboard thickeies into L type limit (A) at right-angle side one end, the other end is little protruding (C) of half dove-tail form, L type main body (1) lower end interposition is equipped with little protruding (B) of a dove-tail form, the groove that little protruding (C) of the L type main body (1) of two different in width or same widths by two half dove-tail forms and ridge are strengthened matrix muscle (2) is closely inlayed and is combined, the L type main body (1) of two different in width or same widths and three ridges are strengthened matrix muscle (2) and are closely inlayed and be combined into the complete U channel section of a cover, and L type main body (1) and ridge reinforcement matrix muscle (2) adopt the mould one-shot forming respectively.

Described L type main body (1) width refers to the length of right-angle side, and L type main body (1) width range is 150mm～300mm, advances level according to the construction needs by 25mm.

The outside, described L type limit (A) interlude slightly concaves, and the outer surface middle is provided with " V " line, becomes the L type below,

It is oblong openings that described ridge is strengthened matrix muscle (2), and opening is the dovetail groove type, and the rectangle bottom is hollow.

Little protruding (C) of described half dove-tail form is half of little protruding (B) of a dove-tail form, and little protruding (C) of half dove-tail form on each L type main body is the same.

The beneficial effects of the utility model are: since the utility model use to be L type main body (1) strengthen matrix muscle (2) two with ridge partly adopts the mould one-shot forming respectively, the L type main body (1) of 2 different in width or same widths and 3 ridges are strengthened the tight mosaic combined complete U channel section of a cover that becomes of matrix muscle (2), owing to adopted 2 L type main bodys (1) to combine, so reduced the difficulty of producing, can take different compound modes according to the construction formwork of the requirement of engineering of constructing, reach the requirement of satisfying various constructions, reduce difficulty and the cost of construction.Because dove-tail form boss (B) is knockdown than the short and small and integral body of traditional reinforcement version, so reduce adding the man-hour difficulty, production efficiency improves, and the finished product scrappage reduces, and reduces and uses material.Owing to adopted dove-tail form protruding (B) and ridge to strengthen matrix muscle (2) compound mode, made that the bearing capacity in the middle of the section bar more strengthens, so get a greater increase in resistance to compression and anti-bending strength.
