Abstract

A building insulation wall fixing expansion nail relates to a building wall fixing appliance and solves the problems that a conventional reinforcement nail has a low expansion coefficient and is easy to fall off, which lead to the shedding of a fixed insulation layer, people and articles are easily to damage after the shedding, the service life time is short and the maintenance cost is high. A screw of the utility model is disposed in an expansion cylinder, wherein a left end of the screw is provided with a convex edge and a right end of the screw is provided with external threads. An axle center of a conical expansion plug is provided with a screw hole. The conical expansion plug is sleeved on the screw. An outer conical surface of the conical expansion plug is arranged in the expansion cylinder, a right end of which, with a dovetail shape, is symmetrically provided with two slots. A pin ear is disposed on the conical expansion plug. A nut cooperates with screw threads. The pin ear is arranged in the slots. The building insulation wall fixing expansion nail of the utility model is high in expansion coefficient, difficult in the shedding of the insulation layer and long in service lifetime, and saves the maintenance cost. The service lifetime and the quality of the insulation layer satisfy the design requirements.

Description

Building heat preservation body of wall fixed expansion nail

Technical field

The utility model relates to the construction wall holding appliance.Be specifically related to a kind of building heat preservation body of wall fixed expansion nail.

Background technology

At present; body of wall all is to adopt haydite or hollow brick and insulation layer (benzene plate or the crowded plate that contracts) wall body structure in multilayer, middle-high building; reinforcing the benzene plate or squeezing when contracting the plate insulation layer and fix with existing nail; because the existing nail coefficient of expansion low (load only is 0.4KN); easily come off; the insulation layer (benzene plate or the crowded plate that contracts) that causes being fixed comes off; after coming off, insulation layer easily hurts sb.'s feelings and damage product; the application life of insulation layer is short; and the expense height of maintenance, the application life of insulation layer and quality do not reach the problem of designing requirement.

The utility model content

The utility model is in order to solve at fixing benzene plate or to squeeze when contracting the plate insulation layer because traditional reinforcing nail coefficient of expansion is low, easily come off, the insulation layer (benzene plate or the crowded plate that contracts) that causes being fixed comes off, after coming off, insulation layer easily hurts sb.'s feelings and damage product, the application life of insulation layer is short, and the expense height of maintenance, and the application life of insulation layer and quality do not reach the problem of designing requirement, a kind of building heat preservation body of wall fixed expansion nail is provided, and the concrete technical scheme that addresses the above problem is as follows:

Building heat preservation body of wall fixed expansion nail of the present utility model, by the tube that expands, screw rod, nut, taper is expanded and is filled in and head of a nail composition, screw rod is located in the tube that expands, the left end of screw rod is provided with the convex edge, the right part of screw rod is provided with external screw thread, have screw hole on the axle center of the bloated plug of taper, nut is wrapped in the bloated plug of taper, and taper is expanded plug sleeve on screw rod, and the male cone (strobilus masculinus) of the bloated plug of taper is located in the bloated tube, the right part symmetry of bloated tube has two cylindrical voids, the right-hand member of bloated tube is swallow-tail form, and taper is expanded and is provided with the pin ear beyond the Great Wall, and nut cooperates with screw flight, the pin ear is located in the cylindrical void, and the left end that the head of a nail is located at the tube that expands is one with the tube that expands.

Building heat preservation body of wall fixed expansion nail of the present utility model, coefficient of expansion height (load is 7.2KN after testing), insulation layer (benzene plate or the crowded plate that contracts) fixing back difficult drop-off, so, hurt sb.'s feelings and the problem of damage product has solved, the long service life of insulation layer (identical) with the life-span of building, and saved maintenance cost, the application life of insulation layer body of wall and quality have reached the advantage of designing requirement.It also is applicable to architectural decoration.

Description of drawings

Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the expand positional structure schematic diagram of plug and nut amplification of taper among Fig. 1, and Fig. 3 is that enlarged drawing is looked on the right side of Fig. 1.10 is external screw thread among the figure.

The specific embodiment

The specific embodiment one: describe present embodiment in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4.Present embodiment is by the tube 1 that expands, screw rod 2, nut 3, the bloated plug 4 of taper and the head of a nail 5 are formed, screw rod 2 is located in the tube 1 that expands, the left end of screw rod 2 is provided with convex edge 6, the right part of screw rod 2 is provided with external screw thread, have screw hole 7 on the axle center of the bloated plug 4 of taper, nut 3 is wrapped in the bloated plug 4 of taper, the bloated plug 4 of taper is enclosed within on the screw rod 2, nut 3 and screw rod 2 threaded engagement, the left conical surface of the bloated plug 4 of taper are located in the tube 1 that expands, and bloated 1 right part symmetry has two cylindrical voids 8, the right-hand member of bloated tube 1 is swallow-tail form, be arranged with two pin ears 9 on the conical surface of the bloated plug 4 of taper, pin ear 9 is embedded in the cylindrical void 8, and the left end that the head of a nail 5 is located at bloated 1 is an one with the tube 1 that expands.

The specific embodiment two: describe present embodiment in conjunction with Fig. 1.The bloated tube 1 of the expandable nail of present embodiment adopts plastics to make.

The specific embodiment three: describe present embodiment in conjunction with Fig. 1, Fig. 2, Fig. 3.The maximum outside diameter of the bloated plug 4 of the taper of present embodiment equates with the external diameter of the tube 1 that expands.

Using method:

After insulation layer set; with boring insulation layer and body of wall boring are reached projected depth; the right-hand member of expandable nail is inserted in the good hole of brill; with spiral shell cutter rotary screw 2; nut 3 promotes taper and expands plug 4 to left movement, and the coefficient of expansion of expandable nail right-hand member is increased, and what the right-hand member of expandable nail was firm is fixed in haydite or the hollow brick wall; and with insulation layer (benzene plate or squeeze contract plate) firm be fixed on haydite or the hollow brick wall never drop-off.
