Abstract

The utility model relates to an aluminum alloy keel used for hanging ceiling, comprising a strip aluminum alloy keel frame whose cross section is inverted U-shaped. The left and right sides of the keel frame are continuously bended inward to form a hook body; a plurality of rectangle concave grooves of same size are arranged on the top surface of the aluminum alloy keel frame at equal interval; rectangle clamp plates integrated with the aluminum alloy keel frame are arranged above the rectangle concave grooves; one side of the rectangle clamp plate on the width direction is connected with the keel frame; the distance between the front and the back rectangle clamp plates is 40 mm. The utility model is used for replacing the wood keel which is not fireproof, not waterproof, easy in deformation and erosion; because the product is specified, the utility model has the advantages of flexible assembly and disassembly, greatly improved installation accuracy, reduced construction period and good entire ceiling hanging effect when the utility model is used and matched with the buckle plate which is widened with equal proportion.

Description

The very useful aluminium alloy joist of a kind of ceiling suspension hook

Technical field

The utility model relates to the building decoration engineering field, relates to the very useful section bar of ceiling suspension hook, specifically, is the very useful aluminium alloy joist of a kind of ceiling suspension hook.

Background technology

In building decoration engineering, the smallpox furred ceiling is one of indispensable content, it has not only played the effect of " hiding shame ", promptly shelter from the various pipelines that are provided with on the roof, room beam etc., main is to have beautified indoor environment, when especially using it between the kitchen or washroom, effects such as protection against the tide, fire prevention, heat insulation, sound insulation, insulation also on certain Cheng Du, have been played.

At present, be used for the very useful section bar of ceiling suspension hook and mainly include corner, keel, buckle, along with the progress of development of times and society, these different section bars also update at the paces in the epoch of following.

In the prior art, in the decorative engineering in places such as family, in order to reduce construction costs, the buckle keel that are used for the smallpox furred ceiling are still mostly that employing is not prevented fires, non-watertight, yielding, perishable rough ground, and expensive lightgage steel joist is used for the decorative engineering of industrial construction mostly.

Adopt rough ground that buckle is installed, because the assembling between buckle and the rough ground is disposablely use the steel nail stickfast, in case when need not in place being installed suitably being adjusted, just can only remove by force, work is scrapped processing, causes material, artificial, temporal waste.Simultaneously, because rough ground is the same with wood flooring, along with variation of temperature can be expanded with heat and contract with cold, the time finally causes whole ceiling suspension hook top surface uneven once the long distortion that can occur in various degree, has directly influenced decorative effect.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art or defective, to provide a kind of ceiling suspension hook very useful aluminium alloy joist.Because the end face of this aluminium alloy joist framework uniformly-spaced is disposed with the rectangular recess of several same size, the top of rectangular recess is provided with the rectangle clamp with aluminium alloy joist framework disjunctor, after the supporting use of buckle of widening with equal proportion, can make installation, dismounting more flexibly and fast, shortened construction period greatly; Because product specification, installation accuracy height not only, the whole structure of smallpox furred ceiling is good especially.

To achieve these goals, the utility model has adopted following technical scheme:

The very useful aluminium alloy joist of a kind of ceiling suspension hook is characterized in that, it comprises that a cross section is the bar shaped aluminium alloy joist framework of inverted u-shaped;

The left and right sides of described keel frame inwardly is bent to form a crozier continuously; The end face of keel frame uniformly-spaced is disposed with the rectangular recess of several same size; The top of this rectangular recess is provided with the rectangle clamp with aluminium alloy joist framework disjunctor.

The above-mentioned very useful keel of a kind of ceiling suspension hook, wherein,

One side of described its width of rectangle clamp links to each other with the aluminium alloy joist framework.

Distance between described former and later two rectangle clamps is 40mm.

Owing to adopted above-mentioned technical scheme, the utility model compared with prior art has following advantage and good effect:

1. the very useful keel of the utility model ceiling suspension hook adopt aluminum alloy material to make, be used for substituting do not prevent fires in the past, non-watertight, yielding, perishable rough ground, the whole structure of smallpox furred ceiling is good especially.

2. because the left and right sides of this keel frame inwardly is bent to form a crozier continuously, the bulk strength of keel frame is obviously strengthened, the thickness of framework sheet material can reduce significantly, thereby, saved material resources.

3. because this product specification, after the supporting use of buckle of widening with equal proportion, not only make installations, dismounting flexibly and fast, installation accuracy increases substantially, and construction period is shortening therefore and greatly also.

Description of drawings

By following examples and in conjunction with the description of its accompanying drawing, can further understand purpose, specific structural features and the advantage of its invention.In the accompanying drawing,

Fig. 1 is the Facad structure schematic diagram of the very useful aluminium alloy joist of the utility model ceiling suspension hook;

Fig. 2 is the A-A line sectional structure schematic diagram of Fig. 1;

Fig. 3 is that the structure for amplifying schematic diagram is looked on the left side of Fig. 1;

Fig. 4 is the B portion structure for amplifying schematic diagram of Fig. 1.

The specific embodiment

The very useful aluminium alloy joist of the utility model ceiling suspension hook as shown in Figure 1, 2, it comprises that a cross section is the bar shaped aluminium alloy joist framework 1 of inverted u-shaped, be used for substituting do not prevent fires in the past, non-watertight, yielding, perishable rough ground, can make the whole structure of smallpox furred ceiling reach optimum state.

Can be clear that from figure the end face of this aluminium alloy joist framework 1 uniformly-spaced is disposed with the rectangular recess 11 of several same size; The top of this rectangular recess 11 is provided with the rectangle clamp 12 with aluminium alloy joist framework 1 disjunctor.

Referring to Fig. 3, because the left and right sides of keel frame 1 inwardly is bent to form a crozier 13 continuously; Keel frame 1 bulk strength is obviously strengthened, and the thickness of framework sheet material can reduce significantly, thereby has saved material resources.

Referring to Fig. 4, a side of rectangle clamp 12 widths links to each other with aluminium alloy joist framework 1.

In the present embodiment, the distance between former and later two rectangle clamps 12 is 40mm, after the supporting use of typing buckle of widening with equal proportion, not only makes installation, dismounting flexibly and fast, and installation accuracy increases substantially, and construction period also shortens therefore and greatly.

Claims

1. the very useful aluminium alloy joist of ceiling suspension hook is characterized in that, it comprises that a cross section is the bar shaped aluminium alloy joist framework of inverted u-shaped;
