Abstract

The utility model provides a tongue-and-groove building external wall board. The external wall board body is in a plate type structure whose upper and lower surfaces are uniformly provided with a plurality of corresponding salient ribs and recesses, and the port of the body is provided with a rabbet and a tongue-and-groove. The salient ribs, the recesses, the rabbet and the tongue-and-groove can be in random geometric shapes, such as a dovetail shape, a rectangle shape, a trapezoid shape, a right triangle shape, etc. The body can be made by light hard building materials, such as the EPS polystyrene foam, the mineral wool, the foamed glass, etc. The salient ribs at the upper and the lower surfaces of the external wall board body and the recesses are firmly linked with a wall body base layer and a protective layer in a tongue-and-groove mode. The utility model overcomes the disadvantages of the traditional connecting mode, and ensures the organic integrative combination of the wall body base layer, the heat insulation layer and the protective layer so as to ensure the integral strength and the heat insulation effect of the external wall board layer.

Description

Tongue and groove external wall plate

Technical field:

The utility model relates to a kind of improvement of building prefabricated components, especially discloses a kind of tongue and groove external wall plate, belongs to the constructional materials technical field of structures.

Background technology:

The building insulating layer structure is substantially at present: body of wall basic unit, building glue bond layer, insulation layer, steel mesh or alkali-resistant glass fibre net, topping and decorative layer are primary structure; Insulation layer and body of wall basic unit and topping connected mode are to build the gluing principal mode of becoming.The insulation layer of this structure and connected mode major technique defective are: construction link is many, technical difficulty is big, long in time limit; and insulation layer is connected insecure with body of wall basic unit and topping; because of the easy season cracking of building glue; cause insulation layer and body of wall basic unit and topping from defectives such as drum, distortion, alice, be full of cracks, infiltration, life-span weak points; cause the big heat insulation effect that influences of later period maintenance amount, the comprehensive total cost height of insulation layer.

Summary of the invention:

The utility model provides a kind of tongue and groove external wall plate, has overcome the shortcoming of the existence of existing building side fascia on construction is used.

Technical solution of the present utility model is as follows: the side fascia body is a plank frame, and upper and lower surface offers some corresponding convex tendons and groove equably, and the port of body offers tenon and tongue-and-groove;

Described convex tendon and groove can be random geometries such as dove-tail form, rectangle, trapezoidal or right-angled triangle;

Described tenon and tongue-and-groove can be random geometries such as dove-tail form, rectangle, trapezoidal or right-angled triangle;

Described body can be made by light body hard constructional materials such as EPS polystyrene foam, mineral wool, foamed glass.

Mode of occupation is: the convex tendon of side fascia body and tenon stretch in the groove and tongue-and-groove of upper strata and right side side fascia body, left side and following groove anyhow are embedded in respectively on the convex tendon and tenon of left side and lower floor's side fascia body, the side fascia body that its side fascia body is adjacent tightly coincide, and forms continuously airtight insulation layer integral body and has guaranteed heat insulation effect.Side fascia body upper and lower faces convex tendon firmly is connected with the cement concrete of tongue-and-groove mode with body of wall basic unit and topping with groove, has guaranteed that side fascia does not come off.

Good effect of the present utility model is: the convex tendon of the upper and lower faces of side fascia body and groove are connected firmly with tongue-and-groove mode and body of wall basic unit and topping; broken through the shortcoming of traditional connected mode; guaranteed that it is one that body of wall basic unit, insulation layer, topping organically combine, and has guaranteed the bulk strength and the heat insulation effect of exterior wall flaggy.
