[0047] The following is combined with Figure 1-12 This application is described in further detail.

[0048] The present application embodiment discloses a building enclosure structure. Figure 1 and Figure 2 As shown, a building enclosure structure includes a vertically arranged enclosure plate 1, the side surface of the enclosure plate 1 is used to press against the side wall of the foundation pit, and the lower surface of the enclosure plate 1 is used to support the bottom of the foundation pit to achieve the enclosure and reinforcement of the edge of the foundation pit.

[0049] An accommodating cavity 11 is provided inside the enclosure plate 1 , a rotating cavity 12 connected to the accommodating cavity 11 is provided on the side of the enclosure plate 1 , and a penetrating cavity 13 connected to the accommodating cavity 11 is provided on the bottom of the enclosure plate 1 .

[0050] A pressure roller 14, a screw rod 15 and a lifting seat 2 are arranged in the accommodating cavity 11. The pressure roller 14 is connected to the enclosure plate 1 by rotating around its own axis. The axial direction of the pressure roller 14 is the same as the width direction of the enclosure plate 1, and the pressure roller 14 is rotatably arranged in the rotating cavity 12; the screw rod 15 is vertically arranged and connected to the enclosure plate 1 by rotating around its own axis. The screw rod 15 is connected to the pressure roller 14 through the linkage unit 3, and the screw rod 15 is threadedly engaged with the lifting seat 2; the lifting seat 2 is slidably embedded in the accommodating cavity 11 along the vertical direction, and a plurality of vertically arranged first pins 21 are installed on the lower surface of the lifting seat 2.

[0051] During the overall transportation of the building envelope structure, the pressure roller 14, the screw rod 15, the lifting seat 2 and the first pin 21 are all hidden in the accommodating cavity 11, so that the building envelope structure is a regular rectangular parallelepiped, so that multiple groups of building envelope structures can be stacked or placed side by side, and the first pin 21 can be prevented from accidentally injuring workers.

[0052] During the enclosure process of the foundation pit, two workers will lift the left and right ends of the enclosure plate 1 respectively, so that the side surface of the enclosure plate 1 with the rotating cavity 12 is pressed against the side wall of the foundation pit, and then the two workers will pull down the enclosure plate 1 together, so that the pressure roller 14 rolls downward on the side wall of the foundation pit. During the rolling process, the pressure roller 14 will drive the screw rod 15 to rotate through the linkage unit 3, and the screw rod 15 will drive the lifting seat 2 to descend. The lifting seat 2 will drive the first pin 21 to descend to the bottom of the enclosure plate 1 through the penetration cavity 13, so that the first pin 21 can be inserted downward into the foundation pit to ensure the stability of the enclosure plate 1 during the enclosure process.

[0053] In summary, by sliding the retaining plate 1 down the side wall of the foundation pit, the first pin 21 can be automatically extended out of the accommodating cavity 11, so as to quickly complete the enclosure of the foundation pit; by sliding the retaining plate 1 on the side wall of the foundation pit, the first pin 21 can be automatically sunk into the accommodating cavity 11, so as to facilitate the overall transportation of the building enclosure structure.

[0054] like Figure 3 and Figure 4 As shown, the linkage unit 3 includes a first gear 31, a rotating shaft 32, a second gear 33, a first bevel gear 34 and a second bevel gear 35. There are two first gears 31 and they are fixedly sleeved on the two ends of the pressure roller 14 respectively; the rotating shaft 32 and the pressure roller 14 are coaxially arranged, and the rotating shaft 32 is connected to the enclosure plate 1 around its own axis; there are two second gears 33 and they are fixedly sleeved on the two ends of the rotating shaft 32 respectively, and the second gear 33 is meshed with the first gear 31; there are two first bevel gears 34 and they are fixedly sleeved on the two ends of the rotating shaft 32 respectively; there are two screw rods 15, there are two second bevel gears 35 and they are fixedly sleeved on the corresponding screw rods 15 respectively, and the second bevel gear 35 is meshed with the first bevel gear 34.

[0055] During the rotation of the pressure roller 14, the pressure roller 14 will drive the second gear 33 to rotate through the first gear 31, the second gear 33 will drive the first bevel gear 34 to rotate through the rotating shaft 32, the first bevel gear 34 will drive the screw rod 15 to rotate through the second bevel gear 35, and the screw rod 15 will drive the lifting seat 2 to perform lifting movement, so that the first insertion pin 21 enters and exits the accommodating cavity 11, thereby realizing the linkage between the pressure roller 14 and the first insertion pin 21.

[0056] It is worth noting that the diameter of the first gear 31 is larger than that of the second gear 33, and the diameter of the first bevel gear 34 is larger than that of the second bevel gear 35, so that the screw 15 can rotate at a faster speed relative to the pressure roller 14, so that the first pin 21 can quickly enter and exit the accommodating cavity 11, thereby improving the enclosure efficiency and storage efficiency of the building envelope structure.

[0057] like Figure 5 , Figure 6 and Figure 8 As shown, a support plate 4 is provided on the lifting seat 2, one end of the support plate 4 is rotatably connected to the lower surface of the lifting seat 2, and the support plate 4 and the lifting seat 2 are commonly connected to the same first torsion spring 41, one end of the first torsion spring 41 is fixedly connected to the support plate 4, and the other end of the first torsion spring 41 is fixedly connected to the lifting seat 2.

[0058] When the support plate 4 is in the accommodating cavity 11, the first torsion spring 41 will be in a deformed state; when the lifting seat 2 drives the first insertion pin 21 and the support plate 4 to disengage from the accommodating cavity 11, the first insertion pin 21 will be inserted downward into the foundation pit, and the first torsion spring 41 will return to its natural state, so that the support plate 4 will flip upward to a horizontal state; thereafter, the lower surface of the support plate 4 will be pressed against the bottom of the foundation pit, and the upper surface of the support plate 4 will be pressed against the top cavity wall of the penetration cavity 13, and at this time, the support plate 4 will be stably supported at the bottom of the foundation pit.

[0059] To sum up, during the retaining process of the foundation pit, by sliding the retaining plate 1 down the side wall of the foundation pit, the first pin 21 can be automatically inserted downward into the foundation pit, and the support plate 4 can be automatically supported at the bottom of the foundation pit, so as to improve the stability of the retaining plate 1 during the retaining process and improve the retaining efficiency of the foundation pit.

[0060] It is worth mentioning that, in the present embodiment, there are two support plates 4, which are respectively arranged at the left and right ends of the enclosure plate 1, and the two support plates 4 can jointly support the enclosure plate 1; the two support plates 4 are commonly connected to the same first connecting rod 49, and the first connecting rod 49 enables the two support plates 4 to be flipped synchronously and connect the two support plates 4 into a whole, so as to improve the supporting effect of the support plates 4 on the enclosure plate 1.

[0061] like Figure 5 , Figure 6 and Fig. 9As shown, a telescopic rod 5 is provided on the support plate 4, and the telescopic rod 5 includes a rotating cylinder 51 and a rotating rod 52. The rotating cylinder 51 is rotatably connected to the upper surface of the support plate 4, and the rotating cylinder 51 and the support plate 4 are commonly connected to the same second torsion spring 53, one end of the second torsion spring 53 is fixedly connected to the rotating cylinder 51, and the other end of the second torsion spring 53 is fixedly connected to the support plate 4; the rotating rod 52 is slidably embedded in the rotating cylinder 51, and the rotating rod 52 is connected to the rotating cylinder 51 through a first spring 54, one end of the first spring 54 is fixedly connected to the rotating rod 52, and the other end of the first spring 54 is fixedly connected to the rotating cylinder 51.

[0062] like Fig.11 and Fig.12 As shown, two grooves 16 are provided on the side of the enclosure plate 1 for the corresponding rotating rods 52 to slide and insert, and magnetic blocks 17 are fixedly embedded in the grooves 16.

[0063] When the support plate 4 rotates to a horizontal state, the second torsion spring 53 will also return to a natural state, so that the rotating cylinder 51 and the rotating rod 52 flip upward, and the first spring 54 will also return to a natural state, so that the rotating rod 52 slides up in the rotating cylinder 51; when the first spring 54, the first torsion spring 41 and the second torsion spring 53 are all in a natural state, one end of the rotating rod 52 will be in the groove 16 and not inserted into the groove 16. At this time, the magnetic block 17 can cause the rotating rod 52 to be inserted into the groove 16 through its own magnetic attraction force, so that the telescopic rod 5, the support plate 4 and the enclosure plate 1 together form a triangular structure, thereby enhancing the stability of the enclosure plate 1 during the enclosure process, so as to further improve the enclosure effect of the enclosure plate 1 on the foundation pit.

[0064] like Figure 7 As shown, the two rotating cylinders 51 are commonly connected to a same second connecting rod 511 , and the second connecting rod 511 enables the two rotating cylinders 51 to be turned synchronously and connects the two rotating cylinders 51 into a whole.

[0065] like Figure 8 and Fig. 9 As shown, two first baffles 42 are installed on the upper surface of the support plate 4. When the telescopic rod 5 is located in the accommodating chamber 11, the first spring 54 will be in a compressed state and prompt the rotating rod 52 to press against the first baffle 42. The first baffle 42 will press the rotating rod 52 into the rotating cylinder 51, so that the telescopic rod 5 is in a shorter state, so that the telescopic rod 5 can be separated from the accommodating chamber 11; when the telescopic rod 5 is separated from the accommodating chamber 11, the second torsion spring 53 will return to a natural state and prompt the rotating cylinder 51 to flip over. The rotating cylinder 51 will drive the rotating rod 52 to rotate and separate from the first baffle 42, so that the support plate 4 supports the enclosure plate 1 through the telescopic rod 5.

[0066] Two second baffles 43 are fixedly connected to the upper surface of the support plate 4. When the second torsion spring 53 returns to its natural state, the rotating cylinder 51 will flip upward and abut against the second baffle 43, thereby limiting the flipping trajectory of the rotating cylinder 51 and ensuring that the rotating rod 52 can accurately stay in the groove 16 so that the magnetic block 17 can suck the rotating rod 52 into the groove 16.

[0067] The second baffle plate 43 is rotatably provided with an arc-shaped second inserting pin 44, and the second inserting pin 44 and the second baffle plate 43 are connected to the same third spring 45, one end of the third spring 45 is fixedly connected to the second inserting pin 44, and the other end of the third spring 45 is fixedly connected to the second baffle plate 43. The second inserting pin 44 is rotatably provided and inserted into the support plate 4. When the support plate 4 is in a horizontal state and the third spring 45 is in a natural state, the lower end of the second inserting pin 44 will be flush with the lower surface of the support plate 4; when the rotating cylinder 51 is turned up and abuts against the second baffle plate 43, the rotating cylinder 51 will push the second inserting pin 44 to turn over, the third spring 45 will be deformed, and the second inserting pin 44 will be rotated downward and inserted into the foundation pit, so that the support plate 4 is fixed at the bottom of the foundation pit, so as to improve the stability of the building enclosure structure during the enclosure process.

[0068] like Fig. 9 and Fig.10 As shown, the side of the rotating cylinder 51 is provided with a penetration groove 55 extending along its own radial direction, and an insertion rod 56 is slidably inserted into the penetration groove 55. The insertion rod 56 is connected to the rotating cylinder 51 through a second spring 57. One end of the second spring 57 is fixedly connected to the insertion rod 56, and the other end of the second spring 57 is fixedly connected to the rotating cylinder 51; a first slot 58 for the insertion rod 56 to be inserted is provided on the side wall of the rotating rod 52.

[0069] When the rotating rod 52 is not inserted into the groove 16, the second spring 57 will be in a deformed state and prompt the insertion rod 56 to press against the side wall of the rotating rod 52; when the magnetic block 17 sucks the rotating rod 52 into the groove 16, the second spring 57 will return to its natural state and prompt the insertion rod 56 to be inserted into the first slot 58. At this time, the rotating rod 52 will be inserted and fixed in the rotating cylinder 51, so that the length of the telescopic rod 5 is fixed, thereby ensuring the supporting effect of the telescopic rod 5 on the protective plate 1, thereby further improving the stability of the protective plate 1.

[0070] like Figures 8 to 10As shown, a reinforcing rod 6 is provided on the support plate 4, one end of the reinforcing rod 6 is rotatably connected to the upper surface of the support plate 4, and this end of the reinforcing rod 6 and the support plate 4 are commonly connected to the same third torsion spring 61, one end of the third torsion spring 61 is fixedly connected to the reinforcing rod 6, and the other end of the third torsion spring 61 is fixedly connected to the support plate 4; the other end of the reinforcing rod 6 is rotatably connected to a slider 62, and a slide groove 59 extending along its own axial direction is provided on the side wall of the rotating cylinder 51, the slide groove 59 is arranged in a dovetail shape, and the slider 62 is slidably embedded in the slide groove 59, so that the slider 62 can only slide along the axial direction of the rotating cylinder 51.

[0071] When the telescopic rod 5 is in the accommodating chamber 11, the third torsion spring 61 will be in a deformed state, and the slider 62 will be located at one end of the rotating cylinder 51 connecting the support plate 4; when the support plate 4 is separated from the accommodating chamber 11, the first torsion spring 41, the second torsion spring 53 and the third torsion spring 61 will all be restored to their natural state, and the support plate 4 will be horizontally supported at the bottom of the foundation pit, and support the enclosure plate 1 through the inclined telescopic rod 5, and the reinforcement rod 6 will be flipped upward so that the slider 62 slides to the penetration groove 55. At this time, the reinforcement rod 6, the rotating cylinder 51 and the support plate 4 will jointly form a triangular structure, and the angle between the reinforcement rod 6 and the rotating cylinder 51 is an acute angle, so that the support plate 4 can support the rotating cylinder 51 through the reinforcement rod 6 to improve the supporting effect of the telescopic rod 5 on the enclosure plate 1.

[0072] like Figure 7 As shown, the two reinforcement rods 6 are commonly connected to the same third connecting rod 64. The third connecting rod 64 enables the two reinforcement rods 6 to be turned synchronously and connects the two reinforcement rods 6 into a whole.

[0073] like Fig. 9 and Fig.10 As shown, a second slot 63 is provided on the slider 62. When the first torsion spring 41, the second torsion spring 53 and the third torsion spring 61 are all in a natural state, the support plate 4 can directly support the enclosure plate 1, support the enclosure plate 1 through the telescopic rod 5, and support the telescopic rod 5 through the reinforcement rod 6. At this time, the second spring 57 will prompt the insertion rod 56 to be inserted into the first slot 58 and the second slot 63, so that the rotating rod 52 and the slider 62 are inserted and fixed, so as to improve the supporting effect on the enclosure plate 1 and the telescopic rod 5.

[0074] like Fig. 9 As shown, two third baffles 46 are fixedly connected to the upper surface of the support plate 4. When the third torsion spring 61 returns to its natural state, the reinforcement rod 6 will flip upward and abut against the third baffle 46, thereby limiting the flipping trajectory of the reinforcement rod 6 and ensuring that the slider 62 can accurately stay in the through groove 55 so that the insertion rod 56 can simultaneously connect and fix the rotating rod 52 and the slider 62.

[0075] The third baffle plate 46 is rotatably provided with an arc-shaped third pin 47, and the third pin 47 and the third baffle plate 46 are connected to the same fourth spring 48, one end of the fourth spring 48 is fixedly connected to the third pin 47, and the other end of the fourth spring 48 is fixedly connected to the third baffle plate 46, and the third pin 47 is rotatably provided through the support plate 4. When the support plate 4 is in a horizontal state and the fourth spring 48 is in a natural state, the lower end of the third pin 47 will be flush with the lower surface of the support plate 4; when the reinforcing rod 6 is turned up and abuts against the third baffle plate 46, the reinforcing rod 6 will push the third pin 47 to turn over, the fourth spring 48 will be deformed, and the third pin 47 will be rotated downward and inserted into the foundation pit, so that the support plate 4 is fixed at the bottom of the foundation pit, so as to improve the stability of the building enclosure structure during the enclosure process.

[0076] The implementation principle of a building enclosure structure in an embodiment of the present application is as follows: during the enclosure process of the foundation pit, two workers will lift the left and right ends of the enclosure plate 1 respectively, so that the side surface of the enclosure plate 1 provided with the rotating cavity 12 is pressed against the side wall of the foundation pit, and then the two workers will jointly pull down the enclosure plate 1, so that the pressure roller 14 rolls downward on the side wall of the foundation pit, and the pressure roller 14 will drive the second gear 33 to rotate through the first gear 31 during the rolling process, and the second gear 33 will drive the first bevel gear 34 to rotate through the rotating shaft 32, and the first bevel gear 34 will drive the screw rod 15 to rotate through the second bevel gear 35, and the screw rod 15 will drive the lifting seat 2 to descend, and the lifting seat 2 will drive the first pin 21 to be inserted downward into the foundation pit, and make the support plate 4 detach from the accommodating cavity 11.

[0077] Then the first torsion spring 41 will return to its natural state, causing the support plate 4 to flip upward to a horizontal state and support the enclosure plate 1, and the second torsion spring 53 will also return to its natural state, causing the rotating cylinder 51 to flip upward and abut against the second baffle 43, and the rotating cylinder 51 will push the second inserting pin 44 to flip downward and insert into the foundation pit, so that the support plate 4 is fixed at the bottom of the foundation pit; the first spring 54 will also return to its natural state, causing the rotating rod 52 to slide up in the rotating cylinder 51 until the rotating rod 52 moves to the groove 16, at which time the magnetic block 17 can use its own magnetic attraction to prompt the rotating rod 52 to be inserted into the groove 16, so that The telescopic rod 5, the support plate 4 and the enclosure plate 1 together form a triangular structure; the third torsion spring 61 will also return to its natural state, the reinforcement rod 6 will flip upward and abut against the third baffle 46, and the reinforcement rod 6 will push the third pin 47 to flip downward and insert into the foundation pit, so that the support plate 4 is fixed at the bottom of the foundation pit. At this time, the reinforcement rod 6, the rotating cylinder 51 and the support plate 4 will together form a triangular structure; the second spring 57 will also return to its natural state and prompt the insertion rod 56 to be inserted into the first slot 58 and the second slot 63, so that the rotating rod 52 and the slider 62 are inserted and fixed to improve the supporting effect on the enclosure plate 1 and the telescopic rod 5.

[0078] During the dismantling process of the building envelope structure, the worker will first pull the insertion rod 56 out of the first slot 58 and the second slot 63, then pull the rotating rod 52 out of the groove 16, then flip the telescopic rod 5 and the reinforcement rod 6 downward, and pull the enclosure plate 1 upward, the pressure roller 14 will drive the lifting seat 2 to rise through the linkage unit 3, and the lifting seat 2 will drive the support plate 4, the telescopic rod 5 and the reinforcement rod 6 to sink into the accommodating cavity 11.

[0079] In summary, by lowering the retaining plate 1 along the side wall of the foundation pit, the retaining plate 1 can stably support and retain the foundation pit, thereby improving the retaining efficiency of the foundation pit.

[0080] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
