Specific implementation method

[0022] Please refer to Figures 1-4 , the present utility model provides a spliced building exterior wall panel structure, including: the wall panel structure is spliced by a plurality of wall panels 1, and one pair of opposite side surfaces of each wall panel 1 are respectively provided with insertion blocks 2, and insertion slots 3 are opened on the other pair of opposite side surfaces of each wall panel 1. The wall panels 1 are connected by inserting the insertion blocks 2 into the insertion slots 3. It is characterized in that a plurality of limit holes 5 are spaced and penetrated near the edge on the front surface of the wall panel 1, the limit holes 5 communicate with the insertion slots 3, and a limit block 4 is arranged on the front surface of the insertion block 2 in a liftable manner. When two wall panels 1 are inserted into each other, the limit holes 5 are clamped and matched with the limit blocks 4;

[0023] A pouring hole one 6 is provided on one side surface of the wall panel 1, the pouring hole one 6 and the insertion slot 3 are respectively located on adjacent side surfaces of the wall panel 1, and the pouring hole one 6 and the insertion slot 3 communicate with each other; a pouring hole two 7 is correspondingly opened on the side surface of the insertion block 2. When two wall panels 1 are inserted into each other, the pouring hole one 6 and the pouring hole two 7 are correspondingly penetrated, and a steel bar 9 is commonly inserted into the penetrated pouring hole one 6 and pouring hole two 7;

[0024] The insertion block 2 is a telescopic structure and can avoid interference when the wall panels 1 are spliced in multiple layers.

[0025] It should be explained that the front surface of the wall panel 1 is Figure 1 the end face shown, and it is also the side on the outside of the wall when the exterior wall is spliced.

[0026] Specifically, when the wall panels 1 are assembled, first control the limit block 4 on the splicing side of the wall panel 1 to lower, then insert the insertion block 2 into the insertion slot 3 of the adjacent wall panel 1, and then control the limit block 4 to rise to clamp and limit the limit hole 5. At this time, the pouring hole one 6 and the pouring hole two 7 coincide. Finally, insert the steel bar 9 into the pouring hole one 6 and the pouring hole two 7 to complete the splicing and fixing of the adjacent wall panels 1.

[0027] When using the spliced wall panel 1 to temporarily build the exterior wall of a building, steel bars 9 can be directly used for fixation, which is convenient for disassembly, assembly and secondary utilization. When using the spliced wall panel 1 to permanently build the exterior wall of a building, after the wall panels 1 are spliced, cement slurry can be injected into the first pouring hole 6 and the second pouring hole 7 through a grouting device to improve the splicing strength and impact resistance of the wall panel 1.

[0028] In this embodiment, a flexible sealing layer 12 is provided on the side surface of the wall panel 1, and the flexible sealing layer 12 is located on the periphery of the insertion groove 3.

[0029] Specifically, on the one hand, the splicing seam can be sealed by the flexible sealing layer 12 to isolate the internal and external spaces, prevent the cement slurry from flowing out, or rainwater from entering. On the other hand, it can play a certain buffering role when the wall is impacted.

[0030] In this embodiment, a first sliding cavity is formed in the insertion block 2, the lower part of the limiting block 4 is slidably arranged in the first sliding cavity, and a first spring 13 is connected between the bottom of the first sliding cavity and the limiting block 4. The first spring 13 is located on both sides of the second pouring hole 7, and an avoidance opening is formed at the bottom of the limiting block 4.

[0031] It should be explained that a guiding arc surface is provided on the side of the limiting block 4 away from the wall panel 1. When splicing the wall panel 1, the guiding arc surface of the limiting block 4 is extruded through the insertion groove 3, so that the first spring 13 is compressed and the limiting block 4 descends. After adjacent wall panels 1 are spliced together, the limiting block 4 coincides with the limiting hole 5, and under the action of the elastic force of the first spring 13, the limiting block 4 rises and is clamped and limited with the limiting hole 5.

[0032] In this embodiment, a plurality of limiting blocks 4 are provided, and a plurality of pouring cavities 8 are formed through the adjacent limiting blocks 4 at intervals. The pouring cavities 8 communicate with the second pouring hole 7.

[0033] Specifically, when grouting the first pouring hole 6 and the second pouring hole 7 with a grouting device, the arrangement of the plurality of pouring cavities 8 makes cement blocks in the shape of the pouring cavities 8 added to the rod-shaped cement column itself. The cooperation of cement and steel bars 9 ensures the strength of the spliced wall panel 1.

[0034] In this embodiment, a second sliding cavity is formed on the side surface of the wall panel 1 where the insertion block 2 is located, the lower part of the insertion block 2 is slidably arranged in the second sliding cavity, and the bottom of the second sliding cavity is elastically connected to the insertion block 2 through a plurality of second springs 14.

[0035] In this embodiment, a first locking hole 10 is formed in the front surface of the wall panel 1. The first locking hole 10 communicates with the second sliding cavity. A second locking hole 11 is correspondingly formed in the insertion block 2. When the insertion block 2 is pressed so that the upper end surface of the insertion block 2 coincides with the upper end surface of the wall panel 1, the projections of the first locking hole 10 and the second locking hole 11 coincide, and a locking block is inserted into the first locking hole 10 and the second locking hole 11.

[0036] Specifically, when splicing and building the wall panels 1 above the second floor, by pressing the insertion block 2 and the limiting block 4 of the bottom wall panel 1 until the upper end surface of the insertion block 2 coincides with the upper end surface of the wall panel 1, and then locking the position of the insertion block 2 with the locking block to avoid interference with the assembly of the upper wall panel 1. After the upper horizontal adjacent wall panels 1 are spliced, the locking block is removed. Under the elastic force of the second spring 14, the insertion block 2 is pushed up into the insertion slot 3 of the upper wall panel 1, and the limiting block 4 is clamped and limited with the limiting hole 5 to complete the splicing and fixing of the wall panel 1 in the vertical direction.

[0037] At the same time, the insertion blocks 2 of the uppermost or two side wall panels 1 can be retracted by the locking blocks, which increases the aesthetics of the spliced building exterior wall.

[0038] In this embodiment, the first pouring hole 6 and the second pouring hole 7 are waist-shaped holes, which increase the moving space of the steel bars 9 and facilitate the grouting operation.

[0039] Preferably, the structure of the steel bars 9 is plate-shaped and column-shaped, which are respectively used when temporarily building the building exterior wall and when permanently building the building exterior wall.

[0040] During specific implementation, when building a short-term used building exterior wall, first control the limiting block on the splicing side of the wall panel to lower, then insert and connect the insertion block with the insertion slot of the adjacent wall panel. After that, control the limiting block to rise to clamp and limit the limiting hole. At this time, the first pouring hole and the second pouring hole coincide. Finally, insert the steel bars into the first pouring hole and the second pouring hole to complete the splicing and fixing of the adjacent wall panels. When building a long-term used building exterior wall, cement slurry can be injected into the first pouring hole and the second pouring hole through a grouting device.

[0041] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
