Abstract

The utility model discloses a hollow porous I-shaped fillet, belongs to a section for supporting and reinforcing during manufacturing of a cast-in-place concrete mold, and aims to provide a plastic steel fillet, which is light in mass, is low in cost, can be used repeatedly and is conveniently clamped by using a clamp. The hollow porous I-shaped fillet comprises an I-shaped body, wherein the body (1) is of a hollow structure; a plurality of transverse support ribs (2) and longitudinal support ribs (3) for partitioning the cavity of the body into a plurality of hole cavities are arranged in the cavity; both sides of an upper flange and a lower flange of the body (1) are provided with raised lines (4) extending inwards. The hollow porous I-shaped fillet is simple in structure, has high rigidity and strength, is prevented from being deformed or cracking, is resistant to acid and alkali corrosion, is mothproof, is flame-retardant, is light in mass, is convenient for demolding, and is a plastic steel fillet capable of replacing a wooden square-column or a steel square tube. Moreover, the clamp can be effectively prevented from being loosened in a sliding way.

Description

I-shaped stupefied of hollow porous

Technical field

The utility model relates to a kind of for supporting, reinforce I-shaped stupefied of cast-in-situ concrete mould; Relate in particular to stupefied of the plastic-steel of a kind of alternative wooden stupefied row culture wingceltis bar, pad a tree, used in making timber for boats; Belong to the section bar that plays supporting, reinforcement effect while making cast-in-situ concrete mould.

Background technology

Wood a tree, used in making timber for boats is to connect monolithic plank to form cast-in-situ concrete mould, or for supporting, reinforce a kind of balk of cast-in-situ concrete mould.At present, there is the defects such as yielding or splitting, high, the reusable number of times of coefficient of losses are few in widely used wooden a tree, used in making timber for boats; And although steel square tube can overcome the above-mentioned defect of wooden a tree, used in making timber for boats, but have that cost is high, heavy, construction dismounting difficulty, easily corrosion, form removal difficulty, the job site deficiencies such as difficulty of processing is large again.

For this reason, applicant has proposed the utility model patent (application number is 201320425036.5) that name is called " plastic-steel hollow porous a tree, used in making timber for boats pipe " on July 17th, 2013, although this patent has effectively overcome the defect of Traditional Wood a tree, used in making timber for boats, but while using it for supporting, reinforcing cast in place concrete form, exist fixture to be difficult to the defect of clamping, be still difficult to meet construction requirement.

Summary of the invention

In order to overcome the defect existing in prior art, the utility model aims to provide that a kind of quality is light, cost is low, can be repeatedly used, and is convenient to I-shaped stupefied of the hollow porous of fixture clamping.

To achieve these goals, the utility model is by the following technical solutions: it comprises the body that is I-shape construction, this body is hollow structure, in the cavity of this body, there are some the horizontal support muscle and the vertical supporting rib that are divided into multiple vestibules, respectively have in the top flange of body and the both sides of bottom flange the raised line extending internally.

The corner of each described vestibule is knuckle.

Compared with the prior art, the utility model is owing to having adopted technique scheme, therefore when taking the utility model as secondary beam (secondary joist), taking i iron as girder, (main joist) combines when supporting concrete blinding, can facilitate fixture clamping; In addition, increase respectively in top flange and the both sides, bottom flange of body the raised line extending internally, therefore can effectively prevent fixture slippage.

The utility model had both been avoided inflammable, the yielding or splitting of wooden a tree, used in making timber for boats, the few defect of high, the reusable number of times of coefficient of losses, has overcome again that steel square tube cost is high, heavy, construction dismounting difficulty, easily corrosion, form removal trouble, the job site deficiencies such as difficulty of processing is large again; Not only have similar wood can saw, can dig, can bonding, available nail or the suitability for secondary processing such as screw is fixing, but also have hardness high, be difficult for strain cracking, acid-alkali-corrosive-resisting, the plurality of advantages such as mothproof, fire-retardant, quality is light, form removal is convenient, cost is low.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 schematic diagram that to be the utility model grip it with fixture when supporting flat die plate.

In figure: body 1, horizontal support muscle 2, vertical supporting rib 3, raised line 4, fixture 5.

Detailed description of the invention

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:

As shown in Figure 1: the I-shape construction that body 1 is hollow, in the cavity of this body, there are some horizontal support muscle 2 and the vertical supporting ribs 3 that are divided into multiple vestibules, at the raised line 4 of the each oriented downward-extension in both sides of body 1 top flange, respectively have upwardly extending raised line 4 in the both sides of body 1 bottom flange

Concentrate for fear of stress, adopt round-corner transition in the corner of described vestibule.

As can be seen from Figure 2: because the both sides, top flange at body 1 and both sides, bottom flange are respectively provided with raised line 4, in the time that the utility model is used for supporting flat die plate, raised line 4 can play the effect that stops 5 two hook-shaped clamping head slippages from body 1 of fixture, thereby ensures that fixture 5 is by body 1 and i iron (not indicating in figure) firm grip.

Claims

1. I-shaped stupefied of a hollow porous, comprise the body that is I-shape construction, it is characterized in that: body (1) is hollow structure, in the cavity of this body, there are some the horizontal support muscle (2) and the vertical supporting rib (3) that are divided into multiple vestibules, respectively have in the top flange of body (1) and the both sides of bottom flange the raised line (4) extending internally.

2. I-shaped stupefied of hollow porous according to claim 1, is characterized in that: the corner of each described vestibule is knuckle.
