Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated buildings, and particularly belongs to an extendable positioning tooling for embedded parts. Background Technique

[0002] Embedded parts are components placed during the casting of a structure. Their main uses include lapping during the construction of the upper structure and facilitating the installation and fixation of the foundation of external engineering equipment. Most embedded parts are made of metals such as steel bars, cast iron, steel, stainless steel, aluminum alloy, etc., but can also be made of non-metallic rigid materials such as wood and plastic.

[0003] Before the foundation of a prefabricated building is cast, embedded parts are placed in the casting area. After the foundation is formed, the embedded parts can facilitate the subsequent installation of the wall. The embedded parts need to be positioned and placed so that the embedded screw on the embedded part aligns with the hole on the wall. This requires accurately measuring whether the distance between two adjacent embedded parts meets the requirements, which is rather troublesome when measuring the distances between multiple embedded parts. Content of the Utility Model

[0004] In view of the above problems, the purpose of the utility model is to provide an extendable positioning tooling for embedded parts. The positioning column is inserted into the hole of the formed wall panel, and the extension length of the extension component is adjusted and fixed so that the distance between the two bottom plates is locked. The entire positioning tooling is taken out and the embedded screw is threadedly connected through the threaded sleeve, so that the embedded screw is positioned and placed to meet the installation requirements of the wall panel. The operation is simple and the construction efficiency can be improved.

[0005] The technical solution adopted by the utility model is as follows:

[0006] An extendable positioning tooling for embedded parts includes at least two bottom plates. A fixed cover is vertically arranged on the bottom plate. A threaded sleeve vertically and movably penetrating through the fixed cover is arranged in the fixed cover. An annular limiting plate for preventing it from moving out of the fixed cover is fixedly sleeved on the threaded sleeve. A positioning column coaxial with the threaded sleeve is arranged at the top of the threaded sleeve. A through hole aligned with the threaded sleeve is opened on the bottom plate. An extension component is connected between the two bottom plates.

[0007] Preferably, the extension component includes two connecting plates respectively connected to the bottom plate. One of the connecting plates is provided with a strip-shaped through groove along the length direction, and the other connecting plate is threadedly connected with a fixed screw. The head of the fixed screw presses against the surface of the connecting plate provided with the strip-shaped through groove.

[0008] Preferably, a strip-shaped sliding block slidably connected to the strip-shaped through groove is arranged on the connecting plate without the strip-shaped through groove.

[0009] Preferably, scale lines are arranged along the length direction on the connecting plate.

[0010] Preferably, a nut is fixedly sleeved on the threaded sleeve.

[0011] Preferably, a limiting screw rod vertically penetrates through the bottom plate in a threaded manner.

[0012] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0013] Insert the positioning column into the hole of the formed wall panel, and adjust the extension length of the fixed extension component to lock the distance between the two bottom plates. Then take out the entire positioning tooling and thread-connect the embedded screw rod through the threaded sleeve, so that the embedded screw rod is positioned and placed to meet the installation requirements of the wall panel. The operation is simple and the construction efficiency can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is combined with Figures 1 - 3 to make a detailed description of the present utility model.

[0023] Embodiment

[0024] A stretchable embedded part positioning tooling includes at least two bottom plates 1. A fixed cover 7 is vertically arranged on the bottom plate 1. A threaded sleeve 2 vertically and movably penetrating through the fixed cover 7 is arranged in the fixed cover 7. An annular limiting plate 8 for preventing it from moving out of the fixed cover 7 is fixedly sleeved on the threaded sleeve 2. A positioning column 3 coaxial with the threaded sleeve 2 is arranged at the top of the threaded sleeve 2. A through hole 4 aligned with the threaded sleeve 2 is opened on the bottom plate 1. A stretching component 9 is connected between the two bottom plates 1.

[0025] The embedded part includes a mounting plate 12 and a pre-embedded screw rod 11 vertically arranged on the mounting plate 12; when the positioning tooling is in use, as Figure 3 shown, after the distance between the two bottom plates 1 is fixed by the stretching component 9, the pre-embedded screw rod 11 is movably penetrated through the through hole 4, and the threaded sleeve 2 is rotated to make the threaded sleeve 2 threadedly connected with the pre-embedded screw rod 11, so as to fixedly install the embedded part under the bottom plate 1. The formwork 10 for pouring encloses a pouring area. The positioning tooling is supported and placed through the formwork 10, and a support member 13 is placed between each bottom plate 1 and the formwork 10. The support member 13 longitudinally supports the bottom plate 1 to reduce the deformation of the whole positioning tooling. After the embedded part is cast and fixed with the foundation, the threaded sleeve 2 is rotated again to remove the positioning tooling for the next use.

[0026] Generally, four pre-embedded screw rods 11 are provided. When the four pre-embedded screw rods 11 pass through the set through holes 4, if they cannot pass through smoothly, it indicates that the pre-embedded screw rods 11 are skewed, and the embedded part needs to be replaced in time to further ensure that the embedded part can be smoothly installed on the wall panel.

[0027] In this application, multiple base plates 1 can be connected to each other using extension components 9 to form a square positioning tooling, which can simultaneously position and place all the embedded parts on the same foundation.

[0028] The extension component 9 includes two connecting plates 903 respectively connected to the base plate 1. One of the connecting plates 903 is provided with a strip-shaped through groove 902 along the length direction, and the other connecting plate 903 is threadedly connected with a fixing screw 901. The head of the fixing screw 901 presses against the surface of the connecting plate 903 provided with the strip-shaped through groove 902.

[0029] The two base plates 1 move relative to each other to stagger the connecting plates 903 and use the fixing screw 901 to clamp and fix the two connecting plates 903, thereby fixing the length of the extension component 9; two fixing screws 901 can be used for pressing and fixing.

[0030] A strip-shaped sliding block 904 slidably connected to the strip-shaped through groove 902 is provided on the connecting plate 903 without the strip-shaped through groove 902. The fixing screw 901 is arranged in the strip-shaped through groove 902 and moves together with the connecting plate 903 provided with the strip-shaped sliding block 904. The strip-shaped sliding block 904 can prevent the two connecting plates 903 from rotating relative to each other.

[0031] Scale lines are arranged along the length direction on the connecting plate 903. The scale lines can facilitate viewing the distance value between the two base plates 1, so that corresponding adjustment can be made to other positioning toolings.

[0032] A nut 6 is fixedly sleeved on the threaded sleeve 2. After the nut 6 is provided, a tool can be used to rotate the threaded sleeve 2.

[0033] A limiting screw 5 vertically penetrates through the base plate 1 in a threaded manner. By setting the limiting screw 5, the distance between the base plate 1 and the mounting plate 12 is controlled, so that the embedded part is kept in a proper position.

[0034] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, various changes and modifications can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
