Abstract

The utility model belongs to the technical field of item corner protective strips and discloses an outside corner protective strip. A flexible and elastic small V-shaped strip is arranged in a flexible and elastic large V-shaped strip, the outer side of the tail part of the small V-shaped strip is integrally connected with the inner side of the tail part of the large V-shaped strip, and a row of flexible and elastic suckers is molded at a certain distance on the inner wall face of each side edge of the small V-shaped strip. The outside corner protective strip has the advantages of good elasticity, uniform wrapping tightness, convenience in construction, production and storage, and reusability, and is suitable to be used as an outside corner protector for decorative boards in building construction.

Description

A kind of external corner ceiling

Technical field

The utility model belongs to article turning guard strip technical field, refers in particular to a kind of external corner ceiling.

Background technology

At present; General ceramic tile, marble slab or other decorative panel paste in the work progress of cylinder or corner at bag; Mostly be to spread on cement cream or other bonding agent be fitted in ceramic tile, marble slab or other decorative panel by convered structure with being coated with, with rope or soft material its parcel tension solidified with wait again, solidify the back and remove wrappage by the junction of convered structure at ceramic tile, marble slab or other decorative panel; The weak point of this job practices is: the one, and the construction technology of wrapping up tension with rope or soft material is complicated; Take more personnel, consume great amount of time, make cost of production high; The 2nd, the tightness of parcel differs, and forms the easy concave and convex phenomena of external surface of stickers, influences outward appearance; The 3rd, run into when collision, occur delamination easily and break etc., the elastic deformation amount is little; The 4th, the material of using mostly can not reuse, and causes the serious waste of the energy, does not meet the construction requirements of environmental protection.

Summary of the invention

The purpose of the utility model provides the tightness unification, easy construction of a kind of good springiness, parcel, the external corner ceiling that can reuse.

The purpose of the utility model is achieved in that

A kind of external corner ceiling; In having gentle flexible big V-type bar, be provided with and have gentle flexible little V-type bar; The afterbody outside of little V-type bar links into an integrated entity with the afterbody inboard of big V-type bar, forms a row on the internal face of each side of little V-type bar at interval and has gentle flexible sucker.

Be formed with V-type or U type gap between the side of above-mentioned big V-type bar and little V-type bar the same side.

The outside intersection rounding off of above-mentioned big V-type bar.

Above-mentioned sucker structure is: there is the dish-type groove front portion of sucker, and the rear appearance of sucker is connected until the internal face with little V-type bar for transferring hole enlargement to by undergauge, and the front surface of every row's sucker flushes.

The anterior external diameter of above-mentioned sucker＞with the external diameter of the internal face junction of little V-type bar.

Above-mentioned big V-type bar, little V-type bar and sucker are processed with having gentle flexible plastic material or silica gel material, and described big V-type bar, little V-type bar and sucker are integral structure.

The utility model is compared the outstanding and beneficial technical effects of prior art:

1, construction technology is simple: two row's suckers of the utility model are pressed into respectively on two faces at turning of the ornament materials that pastes; And press the interior air of dish-type groove of sucker to the greatest extent, promptly accomplished the protection work at turning, and the tightness of parcel is unified; Firmly be pulled outwardly after solidifying; Be dismountable external corner ceiling, need the personnel of construction few, expense is low.

2, the utility model is owing to process with having gentle flexible plastic material or silica gel material; So its good springiness; When running into the external force collision; Can absorb external force preferably, not be prone to, construction quality is had auxiliary protection function preferably because of delamination that collision causes, uneven and break etc.

3, can repeatedly use after the utility model use and the dismounting, economy, environmental protection save material.

4, the utility model is rational in infrastructure, is convenient to manufacture and deposit, and is applicable to the external corner guard member of making decorative panel in the work progress.

Description of drawings

Fig. 1 is that the front view of the utility model is local.

Fig. 2 is that the A-A of Fig. 1 is to sectional view.

Fig. 3 is the three-dimensional partial schematic diagram of the utility model.

The specific embodiment

The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-3:

A kind of external corner ceiling; In having gentle flexible big V-type bar 1, be provided with and have gentle flexible little V-type bar 2; The afterbody outside 3 of little V-type bar 2 links into an integrated entity with the afterbody inboard of big V-type bar 1, forms a row on the internal face 21 of each side of little V-type bar 2 at interval and has gentle flexible sucker 4.

Be formed with V-type or U type gap 5 between the side of above-mentioned big V-type bar 1 and little V-type bar 2 the same sides, the collision of a part of external force can be effectively cushioned in this gap.

Outside intersection 11 rounding ofves of above-mentioned big V-type bar 1 are difficult for by scratch.

Above-mentioned sucker 4 structures are: there is dish-type groove 42 front portion 41 of sucker 4; Rear portion 43 profiles of sucker 4 are for to transfer hole enlargement to until being connected with the internal face 21 of little V-type bar 2 by undergauge; This sucker can directly be used and be pull-in on the smooth decorative board, and undergauge goes out to relax external force to the collision of big V-type bar 1 or pull, and the front surface of every row's sucker flushes; Even to guarantee suction at grade, and reliable absorption.

The anterior D outer diameter of above-mentioned sucker 2＞with the outside diameter d of internal face 21 junctions of little V-type bar 2.

Above-mentioned big V-type bar 1, little V-type bar 2 and sucker 4 usefulness have gentle flexible plastic material or silica gel material is processed, and described big V-type bar 1, little V-type bar 2 and sucker 4 are integral structure, are suitable for large-scale production.

The foregoing description is merely the preferred embodiment of the utility model, is not the protection domain that limits the utility model according to this, so: the equivalence that all structures according to the utility model, shape, principle are done changes, and all should be covered by within the protection domain of the utility model.
