Abstract

The utility model discloses a fastening nail for connection of composite insulation wall layers, belonging to the field of architecture. The utility model is used to overcome the disadvantages of present composite insulation walls that connecting strength between the insulation sheets and the wall base is weak. The fastening nail comprises an outer nail, an inner nail and an inner nail cap strip. The outer nail cap is relatively large, and the nail rod is provided with an axial hole which may be tapped. The inner nail comprises a nail cap and a nail rod, the diameter of the inner nail cap is equal to that of the outer nail rod; and the inner nail rod is provided with screws on the outer surface. The central part of the inner cap strip is provided with a hole through which the inner nail cap can be passed; and one side of the hole is provided with a notch with the diameter equal to that of the inner nail rod. The utility model has the advantages of that the adoption of an inner nail, an outer nail and a strip can realize the connection between insulation sheets and wall base by means of bidirectional clamping. Because nail expansion is eliminated, the design can ensures firmness of the connection, and loose connection. The utility model also has the advantages of simple structure and convenient erection.

Description

Composite heat insulating wall interlayer clench nail

Technical field

The utility model belongs to building field, is specifically related to wall body construction.

Background technology

For save heating in the building or cooling energy consumption, the heat-insulating property that improves building masonry wall has become the emphasis that building trade is paid close attention to.The heat-preserving wall that adheres to adiabator plate on the wall base body that the heat-preserving wall that the concrete block masonry of carrying adiabator plate secretly is arranged of present more employing and common building block or prefabricated big plate constitute.Adhere to the adiabator plate than large format on wall base body, the firm degree of both combinations is technological difficulties.The initial stage that this kind body of wall occurs, employing be that adiabator plate outer cover wire lath is then with the mode of steel nail nail on wall base body, this structure, intensity is very low, under the effect of wall surfacing weight, adiabator plate and wall base body break away from, and even the phenomenon that comes off often takes place.Occurred passing adiabator plate and expanding and be fastened on connected mode on the wall base body, but when being used on the body of wall of frame construction, because of the body of wall non-bearing, intensity is lower, easily by squeeze crack, causing the nail that expands to get loose around the nail hole of expanding, and loses the drawknot effect with the plastics nail that expands thereafter.

Summary of the invention

The purpose of this utility model provides a kind of composite heat insulating wall interlayer clench nail, overcomes composite thermal-insulating wall adiabator plate and the low shortcoming of wall base body bonding strength in the prior art.

Clench nail of the present utility model is made up of outer nail, interior nail and interior ailing cap washer.The head of a nail of outer nail has than the spike bar can be by the axial hole of tap out.Interior nail has the head of a nail, nail bar, and the diameter of interior ailing cap is same as the diameter of outer ailing bar, and interior ailing rod outer surface has screw thread.There is the hole that can pass interior ailing cap at interior ailing cap washer middle part, and a side in hole has the breach that width is equivalent to interior nail shank diameter, more than is basic scheme.

For stoping outer nail to rotate in the process of tightening, of the present utility model further improving is that the ailing cap has upright rib towards a side of nail bar outside.

Use good effect of the present utility model to be: to adopt inside and outside nail and washer, the mode with two sides folder of obtaining interfix adiabator plate and wall base body have been guaranteed the firm degree of combination, have eliminated the phenomenon that gets loose that bloated nail may occur, have simultaneously simple in structure, the advantage of convenient construction.

The specific embodiment

Provide embodiment of the present utility model below in conjunction with accompanying drawing.

With existing manufacturing plastics the expand material and the technology manufacturing outer nail that comprises head of a nail 1-1, nail bar 1-2 as shown in Figure 1 of nail, have on the nail bar that nail bar one side has two upright rib 1-4 of symmetrical distribution and sees through the head of a nail and the bigger bellmouth 1-5 of nail bar one side diameter on endoporus 1-3, the head of a nail.With following closely in the existing technology manufacturing steel that comprises six boat nail cap 2-1, nail bar 2-2 as shown in Figure 2, the diameter of ailing cap equals the diameter of outer ailing bar in the steel, on the nail bar screw thread 2-3 is arranged.Injection moulding manufacturing washer 3 as shown in Figure 3, the washer middle part has interior ailing cap to pass hole 3-1, and the head of a nail passes bore edges has the degree of depth and width to equal the breach 3-2 of interior ailing shank diameter.Below promptly finish enforcement of the present utility model.

Mode of occupation of the present utility model is as shown in Figure 4: see through the nail hole that adiabator plate 4 and wall base body 5 bore the diameter that is slightly larger than outer ailing bar.Interior nail 2 is screwed in the outer hole of following closely on the 1 nail bar.Penetrate outer nail and the interior nail that is engaged togather from adiabator plate one side, and make interior ailing cap pass the opposite side metope of body of wall.Ailing cap and sidesway in then interior ailing cap washer 3 being passed, the nail bar is entered in the breach that the washer head of a nail passes the sky avris, by nail in the head of a nail rotation, stretch in the process in the outside ailing bar of interior nail bar hole, outer head of a nail 1-1 and interior ailing cap washer 3 are clamped together adiabator plate and wall base body.

Claims

1, composite heat insulating wall interlayer clench nail is characterized in that: be made up of outer nail, interior nail and interior ailing cap washer, the head of a nail of outer nail is bigger, but the nail bar has the axial hole of threaded or tapping screw thread; In nail the head of a nail, nail bar are arranged, the diameter of interior ailing cap is same as the diameter of outer ailing bar, interior ailing rod outer surface has screw thread, interior ailing cap washer middle part have can pass in the hole of ailing cap, a side in hole has the breach that width and the degree of depth are followed closely shank diameter in being equivalent to.

2, according to the composite heat insulating wall interlayer clench nail of claim 1, it is characterized in that: the ailing cap has upright rib towards a side of nail bar outside.
