Example 5
With reference to fig. 3, the prefabricated interlocking type external thermal insulation wallboard system of the present invention, in combination with the above embodiment, is further improved as follows: in one embodiment, the outer wall panel 200 is provided with a locking groove 403 at a position where the outer wall panel is engaged with the profiled steel plate at both the upper end and the lower end. The engaging groove 403 forms a step surface on the structural body of the wall panel, and the step height of the engaging groove 403 is less than half of the thickness of the lateral supporting plate of the cross-shaped steel plate 401. After the installation, although a certain gap exists between the two wallboards at the upper side and the lower side, the supporting plate of the cross-shaped steel plate 401 in the middle can be shielded, so that the appearance is more attractive on one hand, and an overlarge connecting gap in the middle is avoided; on the other hand, the small gap can prevent the external water flow from entering into the wall body.
In addition, as another embodiment, the lower end of the external wall panel 200 may be provided with the locking groove 403, and the upper end of the external wall panel 200 does not need to be provided with the locking groove. The support plate under the structure can also be shielded.
As an improvement, the contact length between the supporting plate of the cross-shaped steel plate 401 and the external wall panel is not less than 3/5 of the thickness of the external wall panel 200 and does not protrude from the external wall panel 200. The cross-shaped steel plate 401 mainly functions in supporting and connecting, can slow down the fixed installation requirement of the external wall panel within the limited length range, and if the cross-shaped steel plate is too long and is not easy to be provided with a clamping groove structure, the cross-shaped steel plate can be contacted with the outside and is difficult to be packaged, so that the cross-shaped steel plate is easy to expose and corrode.
Example 6
With reference to fig. 3, the prefabricated interlocking type external thermal insulation wallboard system of the present invention, in combination with the above embodiment, is further improved as follows: the upper end and the lower end of the inner wall panel 300 are also provided with a clamping groove 403 at the part matched with the section steel plate, and the section steel plate is shielded in the clamping groove 403. The structure of the clamping groove 403 is the same as that of the external wall panel, and is used for accommodating the corresponding supporting plate of the profile steel. In other embodiments, the locking groove 403 may be separately provided at the upper end or the lower end of the inner wall panel 300 as needed.
Through the structural design of the clamping groove, the gap formed between the wallboard and the cross beam due to the rib plate can be reduced. The inner wall panel 300 shields the support plate from only one side with respect to the outer wall panel, so that the engaging groove 403 may have a greater depth, for example, the depth of the step surface of the engaging groove 403 is greater than 1/2 of the thickness of the support plate at the corresponding position, or between 1/2 and 2/3.
Example 7
The invention discloses a prefabricated mutual-buckled type external thermal insulation wallboard system, which is further improved by combining the embodiment: when the profiled steel plate is installed, the heat insulation washers 800 are disposed between the profiled steel plate and the external wall panel 200 and the internal wall panel 300, as shown in fig. 2, the heat insulation washers 800 are disposed on both sides of the rib plate on the upper side of the cross-shaped steel plate 401, and the heat insulation washers can prevent the heat inside and outside from dissipating through the long bolts. Similarly, the contact surfaces of the rib plates and the external wall panel 200 or the internal wall panel 300 can be provided with heat insulation gaskets 800 at other parts of the section steel plate to form heat insulation broken bridges so as to keep the heat insulation effect of the wall body.
Example 8
The invention discloses a prefabricated mutual-buckled type external thermal insulation wallboard system, which is further improved by combining the embodiment: the joints and holes formed when the external wall panel 200 and the internal wall panel 300 are installed and fixed are filled with sealant. The formed slab joints comprise slab joints formed when the external wall panels 200 are mutually spliced, and slab joints are formed between the external wall panels 200 and the cross-shaped steel plates 401; the plate seams also include the plate seams formed when the inner wall panels 300 are spliced with each other, the plate seams formed when the inner wall panels are connected with the cross-shaped steel plates 401 and the T-shaped steel plates 402, and the like. The apertures are mainly the gaps formed by the long bolts and the short bolts when being installed. The plate seams and the hole seams can be filled with sealant.
The sealant can be a heat-insulating colloid material or a material with heat-insulating and waterproof functions. The gap is filled by the sealing glue, so that the external wall-hung plate and the building form a whole in appearance, and the service life of the structure can be prevented from being influenced by external pollutants.
Example 9
With reference to fig. 4, the prefabricated interlocking type external thermal insulation wallboard system of the present invention, in combination with the above embodiment, is further improved as follows: in the foregoing embodiment, the external wall panels 200 and the internal wall panels 300 are directly spliced in the horizontal direction, preferably, a longitudinal T-shaped steel plate 700 is arranged at the splicing position of two adjacent external wall panels 200, a clamping groove 403 is formed in a longitudinal side wall of each external wall panel 200, a middle rib plate of each longitudinal T-shaped steel plate 700 is located in the clamping groove 403, and the same longitudinal T-shaped steel plate 700 can penetrate through a plurality of beam structures. .

Furthermore, the longitudinal rib plates of the T-shaped steel plate 700 are plugged in the longitudinal clamping grooves 403, so that the path through which rainwater needs to flow when entering the inner wallboard is further prolonged, and rainwater is not easy to enter one side of the inner wallboard.
For a common installation splicing mode, if the clamping groove is arranged, the gap width is increased, and rainwater infiltration can be easily caused. In the embodiment, the clamping grooves are plugged by the rib plates of the longitudinal T-shaped steel plate 700, so that water is more easily prevented.
