CN201106253Y - Anchorage piece for installation of felt tile - Google Patents

Abstract

The utility model relates to a fastener used for fixing objects, in particular to an anchor part used for installing roofing shingles of buildings. The anchor part comprises two parts which are a steel nail and a washer, wherein, the steel nail consists of a round head and a nail body; the round head is larger and thicker than that of the existing common steel nail. The washer is made of semi-rigid plastic and takes the shape of an inverted flat dish and a round pit with the diameter and the depth appropriate for holding the round head of the steel nail is arranged in the middle of the washer. A through hole, the diameter of which is slightly smaller than that of a steel nail body is arranged in the center of the pit. When anchoring the shingle by using the anchor part, since the forced area is expanded and the contact part of the flexible shingle and the washer edge is also expanded correspondingly, the shearing force of the shingle disperses around and the shingle is not likely to be torn when strong wind blows.

Description

A kind of anchoring piece that malthoid watt is installed

Technical field

The utility model relates to the securing member that mounting article is used, and specifically refers to a kind of anchoring piece that is used to install building roofing malthoid watt.

Background technology

The roof of modern building, the roofing overburden of its rainwater leakage prevention carries out the transition to flexible malthoid watt from rigid objects such as the clay small black tile in past, plain tile, cement tile, ceramic glazed roof tile, and it is good with the waterproof thermal and insulating performance, the roofing load light, color and shape is abundant, easy construction and be subjected to liking of user and constructor deeply.But just because of it lightly and is easily wiped off by strong wind, it self also is subject to exposure in sunshine and phenomenons such as bubbling, gap or dislocation takes place simultaneously.Therefore when construction, except boning, also nail on some steel nails in the above with adhesive special.But all the time, do not have a kind of special-purpose steel nail, just replace with common steel nail.Because the ordinary steel nail head is less, therefore stressed concentrating still easily blown off by strong wind.The applicant has invented a kind of anchoring piece that is exclusively used in fixing malthoid watt, and has obtained splendid effect in years construction practice.

The utility model content

The purpose of this utility model is: at the fixing situation of malthoid watt poor effect of existing common steel nail, and the anchoring piece of the malthoid of the special use that provides a kind of works very well to the user and the unit in charge of construction of malthoid watt watt.

The scheme of the utility model technical solution problem is: the anchoring piece of malthoid watt is divided into steel nail and packing ring two parts.Described steel nail is similar to existing steel nail, also form by round end and nail body two parts, the round end that just will have steel nail now strengthens, thickening, and the about 10mm of its head diameter, thickness 1.0～1.2mm make when anchoring the pressure and the expanded range of pressurizeing to following packing ring and malthoid watt.Described packing ring is made of semirigid working of plastics, the also corresponding increase of its area, and diameter is greater than 25mm.Be provided with the pit of a circle therebetween, the round end of the size of pit diameter and the degree of depth and steel nail is suitable, and the heart is provided with a smaller through hole of diameter than the nail body part of steel nail therein.Whole packing ring is the dinner plate shaped of the shallow shape of back-off, promptly is seen as the arc that upwards arches upward slightly from its radial section, and this is in order to be unlikely to upwarp around the plain washer after penetrating at steel nail.

When the utility model uses on the roofing of paving malthoid watt, after malthoid watt and cement roof bonding, steel nail penetrated carry out anchoring on the cement board surface, because of its lifting surface area enlarges, the also corresponding increase of contact portion of flexible malthoid watt and gasket edges, therefore its shearing force is not easy to tear when big wind is scraped to disperseing all around.And the steel nail round end just enters after hammering in the pit in the middle of the packing ring, and flushes with washer face, and the covering that is unlikely to influence a malthoid watt is pasted.

Description of drawings

Fig. 1 is signal of the present utility model (amplification) figure;

Fig. 2 is the plan view from above of Fig. 1;

Each title and mark among the figure: 1 packing ring, 2. round end, 3. nail body, 4. pit, 5. through hole.

The specific embodiment

As shown in the figure, the utility model is a kind of anchoring piece that is used for fixing the malthoid that covers on the cement pitched roof watt, and it comprises steel nail and packing ring two parts.Described steel nail is made up of round end 2 and nail body 3.Round end 2 is bigger and thick than the round end diameter of existing common steel nail.Described packing ring 1 is by semirigid plastic production, the dinner plate shaped of the shallow shape of its shape such as back-off, and a circular pit 4 is established in the centre, and its diameter and the degree of depth can just be held steel nail round end 2 and be advisable.There is a through hole 5 at pit 4 centers, and its diameter is more smaller than the diameter of steel nail nail body 3.Use fixedly malthoid watt-hour of this product, steel nail is hammered on malthoid watt and the cement roof by packing ring 1 center through hole 5, make the round end 2 of steel nail enter the pit 4 of packing ring 1 central authorities, its header planes is just equal with plane on the packing ring 1.The anchorage point of steel nail and packing ring 1 is usually near the upper edge two jiaos of following a slice malthoid watt, and purpose is to make anchoring piece be hidden in the lap-joint of a slice malthoid watt and following a slice malthoid watt, makes roofing see neat appearance.

Claims (2)

1. the anchoring piece that malthoid watt is installed comprises steel nail and packing ring two parts, it is characterized in that: described steel nail is fused by round end (2) and nail body (3) and forms, and the through hole (5) of steel nail by packing ring (1) central authorities is with malthoid watt and cement roof anchoring installation.

2. the anchoring piece of a kind of malthoid as claimed in claim 1 watt, it is characterized in that: described packing ring (1) plastic production of half steel, the circular shallow dinner plate shaped of its shape such as back-off, there is a pit (4) centre, the diameter of pit (4) and the degree of depth can just be held the round end (2) of steel nail, and pit (4) central authorities are provided with a diameter and follow closely the smaller through hole (5) of body (3) diameter than steel nail.
