Abstract

The utility model discloses a composite thermal insulation wall body block which mainly comprises a structure layer (1) and a thermal insulation layer (2). The structure layer (1) is formed by taking ordinary burn-free cement blocks such as concrete, fly ashes, furnace slags, etc. as raw materials, and the thermal insulation layer (2) adopts polystyrene foam plastics or polyurethane foam plastics. The thermal insulation layer (2) is arranged at the periphery of the circumference of the structure layer (1), the outer surface of the thermal insulation layer (2) is provided with a connecting groove (3), and the upper connecting end surface and the lower connecting end surface of the block are provided with connecting flutes (4). The block of the utility model is compositely formed once, thereby reducing the procedure of pasting in the field in construction, enhancing the construction efficiency and lowering the construction cost, and has inside and outside thermal insulation without the existence of a heat bridge to have remarkable thermal insulation effect. The design of flutes at the upper surface and the lower surface as well as the groove at the outer surface of the thermal insulation layer greatly enhances the wall body intensity and the connecting intensity of the wall body and a floated coat, and is beneficial to prolonging the life of a building.

Description

Composite heat insulating wall block

Technical field

The utility model relates to a kind of building block, especially a kind of composite heat insulating wall block.

Background technology

Existing common walling unit be after body of wall finishes building again at exterior wall paste polystyrene cystosepiment, thereby reach heat insulation effect.Paste operation and be when constructing at the scene and carry out, operation is numerous and diverse, claim for eot, and, to adopt the special bonding mortar that polystyrene board is pasted on body of wall during stickup, this mortar costs an arm and a leg, and is per ton about 4000 yuan, the construction cost height.And other sandwich heat preservation building blocks are to carry several heat insulating materials in building block secretly, its four sides all has the good material of heat conduction to make interior exterior wall produce the heat conduction, in steel wire net rack polystyrene sandwich board (leisure plate), steel wire passes polystyrene foam plate, and it is very close, the heat transfer of steel wire is very fast again, has formed the big conduction heat bridge of tool.Because such heat bridge exists, and is difficult to the heat insulation effect that reaches desirable.

Summary of the invention

The purpose of this utility model is exactly in order to overcome the above problems, the composite heat insulating wall block that provide a kind of and reduce working procedure, reduces construction cost, inside and outside insulation does not have heat bridge to exist.

The utility model composite heat insulating wall block mainly comprises deck and insulation layer, deck is to be that raw material constitutes with common burn-free cement building blocks such as concrete, flyash, slags, insulation layer is to adopt polystyrene foam plastics or polyurethane foam plastics, insulation layer is located at the peripheral of deck all around, and the external surface of insulation layer is provided with the connection groove, and the upper and lower connection end face of building block is provided with the connection groove.

As a kind of improvement of the present utility model, connect groove and be made as dovetail groove.

As another improvement of the present utility model, the connection groove that connects end face of going up of building block is made as the hole groove, and the connection groove of following connection end face is made as several cones.

The utility model building block just unites two into one cement block and outside two kinds of materials of polystyrene foam of inside when producing, once-combined moulding is made in building block, reduced on-the-spot operation of pasting in the construction, improved efficiency of construction, do not need to use expensive special bonding mortar yet, save this part spending, reduced construction cost largely.And, the utility model building block and existing sandwich heat preservation building block maximum different be exactly insulation layer outside, deck is interior, inverted configuration, each cement block periphery is all coating insulation layer, inside and outside insulation, do not have heat bridge to exist, heat insulation effect is remarkable, meets energy-conservation requirement fully.The building block above and below is groove design, make masonry mortar in body of wall, form tongue-and-groove, improved strength of wall body greatly, the trench design of insulation layer appearance has improved the bonding strength of body of wall and floated coat, make bonding force be much higher than the insulation practice that exterior wall is pasted polyphenyl plate, prolonged the life-span of building greatly.

Description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is a vertical view shown in Figure 1.

Fig. 3 looks sectional view for a left side shown in Figure 1.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, the utility model composite heat insulating wall block mainly comprises deck 1 and insulation layer 2, deck 1 peripheral hardware insulation layer 2, insulation layer 2 is combined into one with deck 1, the material of the deck 1 of bearing building block can be selected ordinary concrete and light aggregate concrete for use, light aggregate can adopt gangue, flyash, slag etc., the deck 1 of non-bearing building block can be selected scoria for use, cinder, lytag etc., inside can be made porous or hollow, before the insulation layer 2, after, a left side, right four surfaces are respectively equipped with and connect groove 3, connect groove 3 and can be made as dovetail groove.Floated coat embeds in the groove 3, has improved the bonding strength of floated coat and body of wall, makes bonding force be much higher than the insulation practice that exterior wall is pasted polyphenyl plate, has improved the life-span of building greatly.The upper and lower connection end face of building block is provided with and connects groove 4, makes masonry mortar form tongue-and-groove in body of wall, has improved strength of wall body greatly.The connection groove of going up the connection end face of building block can be made hole groove 41, and the connection groove of following connection end face can be made several cones 42, is convenient to exhaust.In addition, the utility model only needs inner thermal insulating layer 2 is removed a wide foam of spool diameter when indoor layout illumination and Outlet line, and wiring is easily convenient.

Claims (3)

1, a kind of composite heat insulating wall block, mainly comprise deck (1) and insulation layer (2), deck (1) is to be that raw material constitutes with common burn-free cement building blocks such as concrete, flyash, slags, insulation layer (2) is to adopt polystyrene foam plastics or polyurethane foam plastics, it is characterized in that: described insulation layer (2) is located at the peripheral of deck (1) all around, and the external surface of insulation layer (2) is provided with and connects groove (3), and the upper and lower connection end face of building block is provided with and connects groove (4).
