[0032] The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] In the description of the embodiments of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0034] Example 1

[0035] refer to Figure 1-3The present embodiment provides a device for temporary protection and rapid blocking of a material transfer port in aluminum mold construction, which is used to block a temporary material transfer port 8 on a building floor slab body 1. The device comprises a blocking template body 5 located below the temporary material transfer port 8. The cross-sectional area of ​​the blocking template body 5 is larger than the cross-sectional area of ​​the temporary material transfer port 8, so as to tightly block the bottom of the temporary material transfer port 8; a sleeve 2 is passed through the blocking template body 5, an inner rod 3 is passed through the sleeve 2, a top fixing structure 4 is provided at the top end of the inner rod 3, the bottom end of the top fixing structure 4 is pressed against the top surface of the building floor slab body 1, and a detachable bottom fixing structure 7 is provided at the bottom end of the inner rod 3, and the bottom fixing structure 7 presses the blocking template body 5 against the bottom surface of the building floor slab body 1.

[0036] The top fixed structure 4, the inner rod 3, the sleeve 2 and the blocking template body 5 form a C-shaped structure, which is clamped with the building floor body 1 to prevent the blocking template body 5 from falling; and the blocking template body 5 can not only temporarily protect the temporary material transfer port 8 after the building floor body 1 located at the lower layer completes the material transfer to prevent falling objects from injuring people, but also can be used as a casting bottom mold when the temporary material transfer port 8 is finally cast and blocked, which is easy to install and disassemble and efficient.

[0037] The top fixing structure 4 and the inner rod 3 can be an integrally formed structure, or two independent components connected by welding, bolting, etc. The shape of the top fixing structure 4 can also be configured according to specific usage requirements, such as a cross bar shape, a block shape, etc., but it should be noted that the top fixing structure 4 should have a certain length along the radial direction of the inner rod 3 so that it can extend to the top surface of the building floor body 1.

[0038] The sleeve 2 can be made of PVC material, and its length is determined according to the sum of the thickness of the building floor body 1 and the thickness of the blocking template body 5. The through hole 6 opened on the blocking template body 5 for the sleeve 2 should be adapted to the outer diameter of the sleeve 2, so that the gap between the sleeve 2 and the side wall of the through hole 6 is as small as possible to avoid leakage during pouring.

[0039] The bottom fixing structure 7 can use high-strength bolts, and a thread matching the bolts is set at the lower end of the side wall of the inner rod 3. The outer diameter of the high-strength bolts is larger than the through hole 6 on the plugging template body 5 to fix the sleeve 2 on the plugging template body 5.

[0040] Taking the top fixing structure 4 and the inner rod 3 as an example of being integrally formed or welded and fixed, when using the present device, after the blocking template body 5 is pressed against the lower end of the temporary material transfer port 8, a sleeve 2 of suitable length is selected, and the sleeve 2 is installed in the through hole 6 on the blocking template body 5, so that the bottom of the sleeve 2 is flush with the bottom surface of the blocking template body 5, and the inner rod 3 is inserted into the sleeve 2 from top to bottom, and the inner rod 3 is fixed with the bottom fixing structure 7 below the blocking template body 5, and the position of the bottom fixing structure 7 on the inner rod 3 is adjusted so that the top fixing structure 4 and the blocking template body 5 are respectively pressed against the top and bottom surfaces of the building floor body 1; when disassembling, the bottom fixing structure 7 is first removed, and then the inner rod 3 and the top fixing structure 4 are pulled out in the vertical upward direction, and then the blocking template body 5 is separated from the sleeve 2, and the portion of the sleeve 2 that exceeds the bottom surface of the building floor body 1 is scraped off with a scraper.

[0041] During construction with the prior art, the temporary material transfer port 8 is generally not arranged at the main load-bearing and anti-leakage position of the building floor body 1. The sleeve 2 can be selected with a smaller inner diameter as much as possible, so the sleeve 2 can be left in the concrete poured at the temporary material transfer port 8, and then sealed and finished during the later decoration of the building, which does not affect the use function of the building. The inner rod 3, the top fixed structure 4 and the blocking template body 5 are disassembled separately for their secondary use.

[0042] According to the specific stability requirements, several sleeves 2 can be passed through the sealing template body 5 according to the shape of the temporary material transfer port, and the several sleeves 2 are evenly distributed along the circumference of the temporary material transfer port 8, and several groups of inner rods 3, top fixed structures 4 and bottom fixed structures 7 are installed.

[0043] Example 2

[0044] refer to Figure 4-5 , the difference between this embodiment and the first embodiment is that the bottom fixing structure 7 includes a socket 71, a fixing assembly 72, a fixing seat 73 and a fixing hole 74, the lower end of the plugging template body 5 is welded and fixed with a fixing seat 73 near the through hole 6, the inside of the fixing seat 73 is provided with a socket 71, the side of the fixing seat 73 is provided with a fixing assembly 72, and the side of the inner rod 3 is provided with a plurality of fixing holes 74 corresponding to the fixing assembly 72. By adopting the above technical scheme, after the plugging template body 5 is abutted against the lower end of the temporary material transfer port 8, a sleeve 2 of a suitable length is selected, the sleeve 2 is inserted into the through hole 6, and then the inner rod 3 is inserted into the sleeve 2 from top to bottom until the top fixing structure 4 at the top of the sleeve 2 abuts against the top surface of the building floor body 1, at this time, the lower end of the inner rod 3 will pass through the socket 71 inside the fixing seat 73, and then the fixing assembly 72 and the fixing hole 74 on the side of the inner rod 3 can be used to fix the inner rod 3, and the plugging template body 5 can be initially fixed.

[0045] Specifically, the fixing assembly 72 includes a fixing rod 721, a circular limiting plate 722, a spring 723, a pull rod 724 and a handle 725. A circular limiting plate 722 is arranged inside the side of the fixing seat 73, a fixing rod 721 is arranged at one end of the circular limiting plate 722, a pull rod 724 is arranged at the other end of the circular limiting plate 722, a spring 723 is sleeved on the surface of the pull rod 724, and a pull handle 725 is arranged at the other end of the pull rod 724. By adopting the above technical solution, when fixing the inner rod 3, pull the handle 725, the handle 725 pulls the pull rod 724, the pull rod 724 pulls the circular limit plate 722 and the fixing rod 721 and drives the spring 723 to compress. When the inner rod 3 drops to a suitable position, release the handle 725. When the fixing rod 721 is aligned with the fixing hole 74 on the side of the inner rod 3, the spring 723 rebounds, thereby driving the fixing rod 721 to be inserted into the fixing hole 74 to fix the inner rod 3. At this time, the blocking template body 5 can preliminarily block the temporary material transfer port 8.

[0046] Specifically, a circular groove corresponding to the circular limit plate 722 is opened inside the fixing seat 73, and circular holes corresponding to the fixing rod 721 and the pull rod 724 are opened at both ends of the circular groove. The spring 723 is located inside the circular groove. By adopting the above technical solution, the setting of this structure can facilitate the disassembly of the sealing template body 5 at a later time.

[0047] Specifically, the diameter of the insertion hole 71 is consistent with the inner diameter of the sleeve 2. By adopting the above technical solution, the setting of this structure can avoid affecting the fixing work of the inner rod 3 when the plugging template body 5 is fixed.

[0048] When the present embodiment is in use, after the blocking template body 5 is pressed against the lower end of the temporary material transfer port 8, a sleeve 2 of suitable length is selected, the sleeve 2 is inserted into the through hole 6, and then the inner rod 3 is inserted into the sleeve 2 from top to bottom until the top fixing structure 4 at the top of the sleeve 2 abuts against the top surface of the building floor body 1. At this time, the lower end of the inner rod 3 will pass through the insertion hole 71 inside the fixing seat 73, and then the fixing assembly 72 and the fixing hole 74 on the side of the inner rod 3 can be used to fix the inner rod 3, so that the blocking template body 5 can be preliminarily fixed. When fixing the inner rod 3, pull the pull handle 725, the pull handle 725 pulls the pull rod 724, the pull rod 724 pulls the circular limit plate 722 and the fixing rod 721 and drives the spring 723 to compress. When the inner rod 3 drops to a suitable position, release the pull handle 725. When the fixing rod 721 is aligned with the fixing hole 74 on the side of the inner rod 3, the spring 723 rebounds, thereby driving the fixing rod 721 to insert into the fixing hole 74 to fix the inner rod 3. At this time, the blocking template body 5 can preliminarily block the temporary material transfer port 8.

[0049] Example 3

When in use, the screw rod 42 is driven to rotate by turning the turning handle 43, and the screw rod 42 rotates until the turning handle 43 is stuck on the upper end surface of the triangular frame 44, so that the triangular frame 44 is firmly pressed against the top surface of the building floor body 1, and it can also ensure that the blocking template body 5 can be firmly pressed against the bottom surface of the building floor body 1.

[0051] The triangular frame 44 is connected to the inner rod 3 in the above-mentioned detachable manner. Different from the first embodiment, the installation direction of the inner rod 3 is not restricted, and it is more convenient to install, disassemble and adjust, and the construction is more convenient.

[0052] Working principle and use process of the present invention: When the present invention is used, after the blocking template body 5 is pressed against the lower end of the temporary material transfer port 8, a sleeve 2 of suitable length is selected, and the sleeve 2 is inserted into the through hole 6, and then the inner rod 3 is inserted into the inside of the sleeve 2, and the triangular frame 44 is installed on the top of the inner rod 3, and the bottom end of the triangular frame is pressed against the top surface of the building floor body 1. At this time, the lower end of the inner rod 3 will pass through the insertion hole 71 inside the fixing seat 73, and then cooperate with the fixing assembly 72 and the fixing hole 74 on the side of the inner rod 3 to fix the inner rod 3, and the blocking template body can be fixed. 5 is preliminarily fixed. When fixing the inner rod 3, pull the pull handle 725, the pull handle 725 pulls the pull rod 724, the pull rod 724 pulls the circular limit plate 722 and the fixing rod 721 and drives the spring 723 to compress.
