Before the technical solutions of the present application are introduced, it is necessary to explain the background of the invention of the present application.
It is common in the related art that the installation of the insulation board 3 usually requires the processes of mortar protection layer 18, finishing layer construction, etc. The problem of the low efficiency of construction that 3 installation of heated board need plaster the process and bring, but also can avoid the short defect of life that this correlation technique exists.
Based on the difficult problem of inventor consciousness, the inventor provides the construction method of the concrete outer wall heat-insulating layer and the concrete outer wall body, the installation of the heat-insulating plate 3 is creatively arranged in the concrete outer wall pouring process, so that the heat-insulating plate 3 is installed in the formed concrete outer wall in a pre-embedded mode, the problem that the construction efficiency is low due to the fact that the heat-insulating plate 3 needs to be installed in the related technology and a plastering process is avoided, the defect that the service life is short in the related technology can be avoided, and finally the construction efficiency and the construction quality are improved. Therefore, the invention is created.
Referring to fig. 1, 2 and 5, the application provides a construction method of a concrete outer wall heat insulation layer, comprising the following steps:
A. installing an insulation board 3 in a pouring space of the wall template for pouring the concrete outer wall, and fixedly connecting the insulation board 3 to the wall template;
B. and injecting concrete into the pouring space to form the concrete outer wall embedded with the insulation board 3.
The wall formwork comprises an outer formwork 5 and an inner formwork 1, and a space defined by the outer formwork 5 and the inner formwork 1 is a pouring space.
From the construction method described above, the concrete outer wall of the present application can be easily conceived in its concrete structure. Specifically, the concrete outer wall includes a wall body 17 formed by a cavity between the outer form 5 and the insulation board 3, a protective layer 18 formed by a cavity between the inner form 1 and the insulation board 3, and the insulation board 3.
Here, the wall body 17 may include a concrete body and reinforcing bars 2 pre-buried into the concrete body.
Here, the armor layer 18 may include a concrete body and a reinforcing member, such as a reinforcing mesh 4, pre-buried in the concrete. It should be emphasized that the mesh of reinforcing bars 4, in addition to serving as a mechanical reinforcement for the protective layer 18, may also serve as an auxiliary adhesive force for the insulation board 3 to be fixed to the external formwork 5.
The fixing component serving as the insulation board 3 and fixedly connected to the outer formwork 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 insulation board 3 on the inner formwork 1, and the outer counter-pulling screw 12 is used for locking the outer surface of the insulation board 3 on the outer formwork 5.
Therefore, the inner surface and the outer surface of the heat insulation plate 3 are respectively locked with the outer template 5 and the inner template 1 through the inner opposite-pulling screw rod 11 and the outer opposite-pulling screw rod 12. It should be understood that the pair of inner and outer tie rods 11 and 12 may be constructed by tie rods widely used in building forms, and will not be described herein.
It is easy to think of, the inner and outer opposite-drawing screw rods 11, 12 may be unconnected or connected. In the implementation mode of connecting the two, the joint of the inner counter-pulling screw rod 11 and the outer counter-pulling screw rod 12 penetrates through the heat insulation board 3.
As an exemplary implementation manner of installing the ends of the inner and outer opposite-pulling screws 11 and 12 in the insulation plate 3, the fixing assembly further includes a connection sleeve 6 disposed at the ends of the inner and outer opposite-pulling screws 11 and 12.
Therefore, the connecting sleeve 6 is mounted to the mounting member (for example, a metal rod) of the heat insulation board 3 in advance by being sleeved, and the mounting of the inner surface and the outer surface of the heat insulation board 3 with the inner counter-pull screw 11 and the outer counter-pull screw 12 is realized.
During actual construction, the arrangement positions and the number of the inner counter-pulling screws 11 and the outer counter-pulling screws 12 are determined by combining a construction scheme and an optimization model. Heated board 3 is adopted the special hole device processing of getting by heated board 3 manufacture factory by the suggestion that internal split screw 11, outer split screw 12 wear to establish, and it is too big to damage heated board 3 when avoiding non-professional technical personnel to operate, influences the material performance.
In the previous implementation with the protective layer 18 having the mesh of steel reinforcement 4, the connecting sleeve 6 connecting the ends of the outer counter-pulling screws 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 incapable of being attached to the reinforcing mesh sheet 4 when the reinforcing mesh sheet 4 is penetrated, namely preventing the connecting sleeve 6 from being just positioned at the mesh position of the reinforcing mesh sheet 4, and the connecting sleeve 6 is obviously incapable of being attached to the reinforcing mesh sheet 4 at the moment. Moreover, the pressing sheet 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 coupling sleeve 6 connecting the ends of the inner counter-pull screws 11 is provided with a protective washer 8.
The design objectives of the protective gasket 8 are thus: the protection gasket 8 can eliminate the slip that brings because of heated board 3 area of contact undersize when the adapter sleeve 6 contacts heated board 3, improves the locking effect of 11 tip of internal counter-pull screw and heated board 3. Furthermore, the concrete penetrates into the bore of the insulation board 3, which is intended to receive the aforementioned mounting.
The reinforcing mesh 4 can also be fixedly connected to the outer formwork 5 as the heat insulation board 3 to provide auxiliary adhesive force, and in the implementation mode that the outer counter-pulling screw 12 penetrates through the reinforcing mesh 4, the outer counter-pulling screw 12 is only used for connecting the reinforcing mesh 4. Referring to fig. 5, a fixing frame 9 may be further provided for connecting the insulation board 3 to the steel mesh 4.
Therefore, the fixing frame 9 can make up the defect that the reinforcing mesh 4 and the heat insulation plate 3 are connected in a penetrating manner by the external counter-pulling screw 12. At this time, the fixing frame 9 is disposed at the middle position of the steel mesh 4, and the external counter-pull screw 12 is disposed at the end position of the steel mesh 4.
Referring to fig. 7, as an exemplary implementation manner of a specific structure of the fixing frame 9, the fixing frame 9 includes a front clamping piece 13, a rear clamping piece 14, a blocking cap 15, a cap rod 16, and a buckling plate 10 installed on the steel mesh 4, the rear clamping piece 14 is configured to be buckled with the buckling plate 10, and the cap rod 16 is locked by the blocking cap 15 after sequentially passing through the rear clamping piece 14 and the front clamping piece 13.
Therefore, the detachable connection of the reinforcing mesh 4 and the heat insulation board 3 is realized 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 buckling plate 10, and the position adjustment of the reinforcing mesh 4 relative to the heat insulation board 3 is facilitated.
Referring to fig. 3 again, in order to realize the connection between the inner surface of the insulation board 3 and the steel bars 2 of the wall main body 17, smooth round anchor bars 7 may be further provided to be connected and fixed with the steel bars 2 of the wall main body 17 through a member such as a binding wire.
In the concrete pouring process, please refer to fig. 5 again, the dead weight of the concrete is large, the pouring amount and the pouring speed are not controlled properly, the shear wall concrete is easy to extrude the insulation board 3, or the concrete between the insulation board 3 and the reinforcing mesh 4 extrudes the reinforcing mesh 4, so that the reinforcing steel bars 2 on the back of the insulation board 3 are extruded, deformed and expanded outwards, and occupy the space between the reinforcing mesh 4 and the outer template, i.e. the distance h2 between the reinforcing mesh 4 and the outer template cannot be ensured, which can cause the reinforcing mesh 4 to be not wrapped by the concrete, cause quality accidents and seriously affect the appearance of the concrete outer wall; in order to avoid the phenomenon, the belt pressing piece connecting sleeve 6 is connected with the screw arranged on the surface of the heat insulation board 3 and is cooperated with the fixing frame 9 of the reinforcing mesh piece 4 to play a role, so that the distances h1 and h2 between the reinforcing mesh piece 4 and the heat insulation board 3 and between the reinforcing mesh piece 4 and the outer template 5 are ensured, and the variation caused by the extrusion of concrete is avoided.
