Before introducing the technical solution of the present application, it is necessary to set forth the created background of the application.
It is common in the related art that the installation of the insulation board 3 is generally performed by performing the working procedures of mortar protection layer 18, decoration surface layer construction, and the like. The insulation board 3 is installed, the problem of low construction efficiency caused by the plastering procedure is required, and the defect of short service life in the related technology can be avoided.
Based on the above-mentioned problems, the present inventors have proposed a construction method of a concrete exterior wall insulation layer and a concrete exterior wall, in which the installation of the insulation board 3 is creatively laid in the process of pouring a concrete exterior wall, so that the insulation board 3 is installed in a pre-buried manner in the formed concrete exterior wall, the problem of low construction efficiency caused by the plastering process required for installing the insulation board 3 in the related art is avoided, and the defect of shorter service life in the related art is avoided, and finally the construction efficiency and construction quality are improved. Thus, the present application has been created.
Referring to fig. 1, 2 and 5, the application provides a construction method of a concrete external wall heat insulation layer, comprising the following steps:
A. installing an insulation board 3 in a pouring space of a wall template for pouring a concrete outer wall, and fixedly connecting the insulation board 3 to the wall template;
B. and injecting concrete into the pouring space to form a concrete outer wall pre-embedded with the heat insulation plate 3.
The wall form board belongs to common knowledge, and is provided with an outer form board 5 and an inner form board 1, wherein a space enclosed between the outer form board 5 and the inner form board 1 is a pouring space.
The concrete structure of the concrete outer wall of the present application can be easily conceived by the above construction method. Specifically, the concrete outer wall includes a wall body 17 formed by cavity molding between the outer form 5 and the heat-insulating plate 3, a protective layer 18 formed by cavity molding between the inner form 1 and the heat-insulating plate 3, and the heat-insulating plate 3.
Here, the wall body 17 may include a concrete body and reinforcing bars 2 embedded in the concrete body.
Here, the protective layer 18 may include a concrete body and reinforcing members, such as reinforcing mesh 4, pre-buried within the concrete. It should be emphasized that the reinforcing mesh 4 may be used as the insulation board 3 to be fixedly connected to the outer form 5 to provide auxiliary adhesion, in addition to enhancing mechanical strength for the protective layer 18.
The fixing component for fixedly connecting the thermal insulation board 3 on the outer template 5 to provide main adhesive force comprises an inner counter-pulling screw 11 and an outer counter-pulling screw 12, wherein the inner counter-pulling screw 11 is used for locking the inner surface of the thermal insulation board 3 on the inner template 1, and the outer counter-pulling screw 12 is used for locking the outer surface of the thermal insulation board 3 on the outer template 5.
Thus, the inner surface and the outer surface of the heat insulation plate 3 are locked with the outer template 5 and the inner template 1 respectively through the inner counter-pulling screw 11 and the outer counter-pulling screw 12. It should be appreciated that the above-mentioned counter screws of the inner counter screw 11 and the outer counter screw 12 may take the form of a counter screw widely applied to building templates, and will not be described herein.
It is easily understood that the inner and outer split screws 11 and 12 may not be connected to each other or may be connected to each other. In the implementation mode of connecting the two, the connection part of the inner counter-pulling screw 11 and the outer counter-pulling screw 12 passes through the heat insulation plate 3.
As an exemplary implementation of the installation of the ends of the inner and outer split screws 11, 12 at the insulation board 3, respectively, the above-mentioned fastening assembly further comprises a connection sleeve 6 provided at the ends of the inner and outer split screws 11, 12.
In this way, the connecting sleeve 6 is fitted to the fitting member (for example, a metal rod) of the heat-insulating plate 3 in advance by sleeving, so that the inner surface and the outer surface of the heat-insulating plate 3 are fitted to the inner counter-pulling screw 11 and the outer counter-pulling screw 12, respectively.
In actual construction, the arrangement positions and the number of the inner counter-pulling screw rods 11 and the outer counter-pulling screw rods 12 are determined by combining a construction scheme and an optimization model. The proposal that the heat-insulating plate 3 is penetrated by the inner counter-pulling screw 11 and the outer counter-pulling screw 12 is processed by a special hole taking device adopted by a manufacturer of the heat-insulating plate 3, so that the heat-insulating plate 3 is prevented from being damaged too much when being operated by non-professional technicians, and the material performance is prevented from being influenced.
In the implementation of the protective layer 18 with the reinforcing mesh 4, the connecting sleeve 6 connected to the end of the external split screw 12 is provided with a pressing piece.
Therefore, the pressing sheet is used for preventing the connecting sleeve 6 at the end part of the external counter-pulling screw rod 12 from being attached to the reinforcing mesh 4 when the reinforcing mesh 4 is worn, namely, preventing the connecting sleeve 6 from being just positioned at the mesh position of the reinforcing mesh 4, and the connecting sleeve 6 obviously cannot be attached to the reinforcing mesh 4. Furthermore, the pressing piece can also eliminate the sliding caused by the small contact area of the connecting sleeve 6 when the connecting sleeve 6 contacts the reinforcing mesh 4.
Referring to fig. 6 and 5, in an exemplary embodiment, the connecting sleeve 6 connecting the ends of the inner split screws 11 is provided with a protective spacer 8.
The design objectives of the protection pad 8 are thus: the protection gasket 8 can eliminate the sliding caused by the small contact area of the heat preservation plate 3 when the connecting sleeve 6 contacts the heat preservation plate 3, and improves the locking effect of the end part of the internal counter-pulling screw 11 and the heat preservation plate 3. Furthermore, the concrete penetrates into the drilled holes of the insulation board 3, which are intended to accommodate the aforementioned mounting elements.
The reinforcing mesh 4 can be fixedly connected to the outer formwork 5 as the heat insulation plate 3 to provide auxiliary adhesive force, and in the implementation mode that the external counter-pulling screw 12 penetrates through the reinforcing mesh 4, the reinforcing mesh 4 is only connected outside the external counter-pulling screw 12. Referring to fig. 5, a fixing frame 9 may be further provided to connect the reinforcing mesh 4 with the heat insulation board 3.
Therefore, the fixing frame 9 can make up for the defect that the external counter-pulling screw 12 is used for connecting the reinforcing mesh 4 and the heat insulation board 3 in a penetrating way. At this time, the fixing frame 9 is disposed at the middle position of the reinforcing mesh 4, and the external split screws 12 are disposed at the end positions of the reinforcing mesh 4.
Referring to fig. 7, as an exemplary implementation of a specific construction of the fixing frame 9, the fixing frame 9 includes a front clip 13, a rear clip 14, a blocking cap 15, a cap bar 16, and a clip 10 mounted on the reinforcing mesh 4, wherein the rear clip 14 is configured to be fastened to the clip 10, and the cap bar 16 is locked by the blocking cap 15 after sequentially passing through the rear clip 14 and the front clip 13.
Therefore, through the mutual matching of the front clamping piece 13, the rear clamping piece 14, the plugging cap 15, the cap rod 16 and the buckle plate 10, the detachable connection of the reinforcing mesh 4 and the heat insulation plate 3 is realized, and the position adjustment of the reinforcing mesh 4 relative to the heat insulation plate 3 is facilitated.
Referring again to fig. 3, in order to achieve connection of the inner surface of the insulation board 3 with the reinforcing bars 2 of the wall body 17, a smooth round anchor bar 7 may be further provided to be connected and fixed with the reinforcing bars 2 of the wall body 17 by means such as tie wires.
In the concrete pouring process, please refer to fig. 5 again, the dead weight of the concrete is larger, the pouring amount and the pouring speed are controlled improperly, the shear wall concrete is easy to squeeze the heat insulation board 3, or the concrete between the heat insulation board 3 and the steel bar net 4 squeezes the steel bar net 4, so that the steel bar 2 on the back of the heat insulation board 3 is squeezed, deformed and swelled outwards, and occupies the space between the steel bar net 4 and the outer mould, namely, the distance h2 between the steel bar net 4 and the outer mould cannot be ensured, the steel bar net 4 cannot be wrapped by the concrete, quality accidents are caused, and the appearance of the concrete outer wall is seriously affected; in order to avoid the phenomenon, the screw rod with the pressing sheet connecting sleeve 6 and the surface of the heat-insulating plate 3 are adopted to be connected, and the screw rod is cooperated with the fixing frame 9 of the reinforcing mesh 4 to play a role, so that the distances h1 and h2 between the reinforcing mesh 4 and the heat-insulating plate 3 and between the reinforcing mesh 4 and the outer template 5 are ensured, and the change caused by the extrusion of concrete is avoided.
The operation of the construction method of the present application will now be described with respect to a common application scenario. It should be noted that this common embodiment is not to be taken as a basis for understanding the essential characteristics of the application claimed to solve the technical problem, but is merely exemplary.
