[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0031] Example 1 Reference Figure 1-Figure 7 , which is the first embodiment of the present invention, provides a prefabricated component assembly positioning device for construction, including a positioning base plate 1, an inclined support rod 11 is installed on the top of the positioning base plate 1, a movable plate 111 is installed on the end of the inclined support rod 11, a positioning edge 12 is installed on one side of the positioning base plate 1, and the positioning edge 12 is installed in contact with the base 13. When the prefabricated component is installed, the prefabricated component is hoisted as close to one side of the base 13 as possible, and the connecting block 2 is riveted into the outer wall of the prefabricated component; A connecting block 2 is installed on one side of the movable plate 111, and a sliding groove 21 is provided on the outer wall of the connecting block 2. An inner slider 22 is installed on the movable plate 111 through the sliding groove 21. A vertical trigger block 23 is installed on the outer wall of the inner slider 22. A snap-fit ​​member 24 is installed on the top of the inner slider 22. A display liquid column 25 is installed on the outer wall of the connecting block 2. A snap-fit ​​member 26 is provided on the inner wall of the connecting block 2, and the snap-fit ​​member 24 is embedded in the inside of the snap-fit ​​member 26. When in a vertical state, the snap-fit ​​member 24 does not affect the direct sliding of the inner slider 22 and the connecting block 2. When in a non-vertical state, the snap-fit ​​member 24 is locked by the vertical trigger block 23, so that the inner slider 22 and the connecting block 2 are also locked.

[0032] Specifically, the L-shaped positioning edge 12 of the positioning base plate 1 is fitted with a corner of the edge of the base 13, and the oblique support rod 11 is a hydraulic rod that is retracted and retracted, so that the hydraulic rod can correct the verticality of the prefabricated part.

[0033] Specifically, the angle between the pressure-contact rod 233 and the gravity drop block 234 is 180 degrees. The gravity drop block 234 is an arc-shaped metal block with a large mass. Its pressure block 235 extends along the axis position on the inner wall of the vertical trigger block 23. When the pressure-contact rod 233 rotates, it can contact and press the pressure block 235. The vertical trigger block 23 is disc-shaped, and the axis of the fixed shaft 231 is consistent with the axis of the vertical trigger block 23.

[0034] Furthermore, a transmission belt 2351 is installed on the outer wall of the pressure block 235, a steering shaft 2352 is installed on the inner wall of the vertical trigger block 23, a limit block 2353 is installed on the inner wall of the vertical trigger block 23, and one end of the transmission belt 2351 is connected to the outer wall of the limit block 2353 after being turned by the steering shaft 2352, and a group of springs are installed on the inner wall of the vertical trigger block 23, and the springs apply elastic force to the limit block 2353 toward one side of the axis of the vertical trigger block 23, and Another set of springs is installed on the inner wall of the vertical trigger block 23, which applies elastic force to the pressure block 235 on one side of the axis of the vertical trigger block 23, and the elastic force of the spring of the pressure block 235 is greater than the elastic force of the spring of the limit block 2353. When the connecting block 2 is perpendicular to the prefabricated plate at ninety degrees, its contact pressure rod 233 contacts the pressure block 235 to move, and the movement of the pressure block 235 loosens the transmission belt 2351. At this time, the spring retracts the limit block 2353 into the interior of the vertical trigger block 23.

[0035] Furthermore, the fastener 24 includes a guide plate 241 installed on the top of the inner slider 22, and an embedded plate 242 is installed through the guide plate 241. One end of the embedded plate 242 extends to one side of the slot 26, and the other end of the embedded plate 242 extends to one side of the limit block 2353. A compression spring 243 is installed on the outer wall of the guide plate 241, and a connecting plate 244 is installed on one end of the compression spring 243. The connecting plate 244 is connected to the embedded plate 242. The compression spring 243 embeds the embedded plate 242 into the slot 26. The end of the embedded plate 242 and the inside of the slot 26 are both triangular inclined surfaces. When the embedded plate 242 moves, the embedded plate 242 can be repeatedly pressed and moved. When the connecting block 2 is vertical, the connecting block 2 and the inner slider 22 can slide and move.

[0036] The rest of the structure is the same as that of Example 1.

[0037] Operation process: workers can push the bottom end of the prefabricated part so that the bottom end of the prefabricated part fits on the positioning edge 12 of the positioning bottom plate 1. At this time, the prefabricated part is slightly inclined, and the upper end of the prefabricated part deviates from the positioning surface. At this time, the hydraulic rod of the inclined support rod 11 pulls the prefabricated part to move, so that the prefabricated part can be gradually restored to a vertical state by pulling the top end of the prefabricated part. At this time, the gravity of the prefabricated part is mainly borne by the hoisting part, and the inclined support rod 11 applies a pulling force to the top end of the prefabricated part. A side thrust is manually applied to the bottom of the prefabricated part. When the prefabricated part is in a vertical state, its gravity drop block 234 drives the contact pressure rod 233 to move, and the contact pressure rod 233 contacts and presses its pressure block 235. The pressure block 235 35 moves and drives the transmission belt 2351 to move. The transmission belt 2351 is loosened, so that the spring drives the limit block 2353 to move, so that the limit block 2353 retracts into the vertical trigger block 23. At this time, the connecting plate 244 is no longer restricted, and its connecting block 2 can contact and press to drive the embedded plate 242 to move. At this time, the hanging parts of the prefabricated parts slowly descend, so that the prefabricated parts can maintain a vertical state and move down along its positioning edge 12, thereby avoiding contact with the steel bars in a non-vertical state. At this time, the prefabricated parts can be smoothly docked with the base 13, and after docking, its verticality is always maintained by the inclined support rod 11, so that the positioning assembly process and the positioning maintenance process can be smoothly docked.

[0038] Example 2 Reference Figure 8 This embodiment is different from the above embodiments in that: the display liquid column 25 is installed on the top side of the connecting block 2, and a pressure-bearing inclined block 251 is installed inside the display liquid column 25, and the pressure-bearing inclined block 251 extends into the interior of the connecting block 2, and a piston member 252 is installed inside the display liquid column 25, and the piston member 252 is filled with a colored liquid, and the colored liquid can be mercury or other liquid that does not stick to the inside of the display liquid column 25.

[0039] The rest of the structure is the same as that of Example 2.

[0040] Operation process: When the prefabricated part is installed, its inner slider 22 touches and presses the compressed inclined block 251, and the degree of compression of the compressed inclined block 251 of different prefabricated parts is also different. The movement of the compressed inclined block 251 drives the piston member 252 to move, and the piston member 252 squeezes its colored liquid, so that the colored liquid enters the scale end of its display liquid column 25. At this time, the staff can record its scale number on the surface of the prefabricated part. If the prefabricated part tilts during the support stage of the inclined support rod 11, the squeezing degree of its compressed inclined block 251 changes, and the scale of its display liquid column 25 also changes, so as to facilitate the subsequent judgment of whether the prefabricated part is successfully cast and installed.

[0041] Working principle: When the prefabricated parts are installed, the positioning base plate 1 is riveted and installed on one side of the base 13, and the positioning edge 12 is installed in close contact with the base 13. The prefabricated parts are hoisted as close to one side of the base 13 as possible, and the prefabricated parts are as close to the diagonal side of the positioning edge 12 as possible, so that the prefabricated parts can be easily fitted with the positioning edge 12. At this time, the hydraulic rod of the oblique support rod 11 is extended, and the connecting block 2 is riveted into the outer wall of the prefabricated part on the top side. At this time, the connecting block 2 and the prefabricated part are in a vertical state, and its limit block 2353 is against the connecting plate 244, so that the connecting plate 244 cannot move, thereby making the inner slider 22 The prefabricated part is in an inclined state, and the upper end of the prefabricated part deviates from the positioning surface. At this time, the hydraulic rod of the inclined support rod 11 pulls the prefabricated part to move, so that the prefabricated part can be gradually restored to a vertical state by pulling the top of the prefabricated part. The gravity of the prefabricated part is mainly borne by the hoisting part. The inclined support rod 11 applies a pulling force to the top of the prefabricated part. The worker applies a lateral thrust to the bottom of the prefabricated part. When the prefabricated part is in a vertical state, its gravity drop block 234 drives the touch-pressure rod 233 to move, and the touch-pressure rod 233 The pressure block 235 is pressed and the pressure block 235 moves, driving the transmission belt 2351 to move. The transmission belt 2351 is loosened, so that the spring drives the limit block 2353 to move, so that the limit block 2353 retracts into the vertical trigger block 23. At this time, the connecting plate 244 is no longer restricted, and its connecting block 2 can press and drive the embedded plate 242 to move. At this time, the hanging part of the prefabricated part slowly descends, so that the prefabricated part can maintain a vertical state and move down along its positioning edge 12, thereby avoiding the non-vertical state from pressing the steel bars. At this time, the prefabricated part can be smoothly docked with the base 13, and after docking, its verticality is always controlled by the inclined support rod 11. Maintain, so that the positioning assembly process and the positioning maintenance process can be smoothly connected, and after the connection is completed, the pressure-bearing inclined block 251 is squeezed and moved by the inner sliding block 22, and the movement of the pressure-bearing inclined block 251 drives the piston member 252 to move, and the piston member 252 squeezes its colored liquid, so that the colored liquid enters the scale end of its display liquid column 25. At this time, the staff can record its scale number on the surface of the prefabricated part. If the prefabricated part tilts during the supporting stage of the inclined support rod 11, the squeezing degree of the pressure-bearing inclined block 251 changes, and the scale of the display liquid column 25 also changes, so as to facilitate the subsequent judgment of whether the prefabricated part is successfully cast and installed.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
