The guide rail 1 is divided into a front section 101, a middle section 102 and a rear section 103 from front to back. Hinges are installed between the right side of the front section 101 and the right side of the middle section 102, and between the right side of the middle section 102 and the right side of the rear section 103, so that the guide rail 1 has a retracted state; a slider 2 sliding on the Y axis is provided on the guide rail 1, and a bolt 21 in contact with the guide rail 1 is threadedly connected to the right side of the slider 2, and a slide rail 3 sliding on the Z axis is provided on the left side of the slider 2, and the lower right side of the slide rail 3 is connected to the A protrusion 31 is connected. When the slide rail 3 slides upward, the protrusion 31 will contact the slider 2 to limit the sliding range of the slide rail 3. A positioning plate 4 is fixedly connected to the left side of the slide rail 3. Connecting columns 5 are fixedly connected to the four corners of the front side of the positioning plate 4. A fixing plate 6 is commonly connected between the four connecting columns 5. A plurality of detection rods 7 for extending into the positioning holes 71 are slidably connected to the positioning plate 4. The front ends of the detection rods 7 slide through the fixing plate 6. An installation mechanism is provided on the guide rail 1, and the guide rail 1 is installed on the prefabricated component 70 through the installation mechanism; a limiting mechanism for fixing the position of the detection rod 7 is provided on the front side of the positioning plate 4.

[0032] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 The limiting mechanism includes a mounting column 81, a second bolt 82 and a rubber block 83. The mounting column 81 is symmetrically fixedly connected to the front side of the positioning plate 4. A row of second bolts 82 are threadedly connected to the mounting column 81 at intervals. The ends of the second bolts 82 are fixedly connected with rubber blocks 83 for pressing on the surface of the detection rod 7. The number of rubber blocks 83 is consistent with the number of detection rods 7.

[0033] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 and Fig. 9 The installation mechanism includes a limit column 91, a screw 92 and a limit block 93. The bottom of the front section 101 of the guide rail 1 is fixedly connected to the limit column 91, and the bottom of the rear section 103 of the guide rail 1 is provided with a limit block 93 sliding on the Y axis. The rear part of the rear section 103 of the guide rail 1 is threadedly connected with the screw 92, and the end of the screw 92 is rotatably connected to the limit block 93.

[0034] refer to Figure 3-Figure 6The positioning detector for assembled precision-built steel bars also includes a round block 110, a push plate 111 and a magnetic block 112. The front end of the detection rod 7 is fixedly connected to the round block 110. A push plate 111 sliding on the detection rod 7 is provided in front of the fixed plate 6. The push plate 111 moves forward and contacts with the round block 110. The fixed plate 6 is made of iron. Two magnetic blocks 112 for sucking the fixed plate 6 are connected to the rear side of the push plate 111.

[0035] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 The positioning detector of the assembled precision-built steel bars also includes a connecting plate 121 and an insert rod 122. The front end of the front section 101 of the guide rail 1 is connected to the connecting plate 121. The right end of the connecting plate 121 is provided with an insert rod 122 that slides back and forth. A return spring is fixedly connected between the insert rod 122 and the connecting plate 121. A socket 123 is provided on the rear side of the rear section 103 of the guide rail 1. By inserting the insert rod 122 into the socket 123, the guide rail 1 can be kept in a retracted state.

[0036] The first step is to install the guide rail 1 on the first prefabricated component 70: place the guide rail 1 on the top surface of the prefabricated component 70, and make the rear side of the limit column 91 close to the front side of the prefabricated component 70, align the detection rod 7 with the positioning hole 71 in the Y-axis direction, and then rotate the screw 92. Under the action of the threaded connection, the limit block 93 slides in the Y-axis direction, so that the front side of the limit block 93 is close to the rear side of the prefabricated component 70, thereby limiting the guide rail 1 through the limit column 91 and the limit block 93, so that the guide rail 1 is installed on the prefabricated component 70.

[0037] The second step is to detect the depth of the positioning hole 71 of the first prefabricated component 70: pull the push plate 111 forward along the Y axis, the magnetic block 112 separates from the fixed plate 6, and when the push plate 111 contacts the round block 110, continue to pull the push plate 111 forward, and the push plate 111 drives the round block 110 and the detection rod 7 to move forward together. Figure 6 State; push the slider 2 to move backward on the guide rail 1, drive the slide rail 3 and the positioning plate 4 to move backward, so that the positioning plate 4 is close to the front side of the prefabricated component 70, and tighten the bolt 21 to fix the position of the slider 2; then push the detection rod 7 backward in turn, so that the detection rod 7 extends into the deepest part of the positioning hole 71, at this time, the push plate 111 can be reset to the initial position, the magnetic block 112 is sucked on the fixing plate 6, and finally tighten the bolt 2 82. Under the action of the threaded connection, the bolt 2 82 and the rubber block 83 are close to the detection rod 7, so that the rubber block 83 is in close contact with the detection rod 7, thereby fixing the relative position of the detection rod 7 and the positioning plate 4. For specific reference to the state at this time Figure 1 The length of the rear end of the detection rod 7 extending from the positioning plate 4 is equal to the depth of the positioning hole 71 .

[0038] The third step is to install the guide rail 1 on the second prefabricated component 70: loosen the bolt 21, push the slider 2 forward, drive the slide rail 3, the positioning plate 4 and the detection rod 7 to move forward as a whole, and make the detection rod 7 leave the positioning hole 71; turn the screw 92 to make the limit block 93 loosen the prefabricated component 70, and install the guide rail 1 on the second prefabricated component 70 through the limit column 91 and the limit block 93 according to the principle of the first step.

[0039] The fourth step is to compare the length of the steel bar 72: push the slide rail 3 to slide upward, drive the positioning plate 4, the connecting column 5, the fixing plate 6 and the detection rod 7 to move upward to a position higher than the top surface of the prefabricated component 70, push the slider 2 to move backward, align the rear side of the positioning plate 4 with the rear side of the prefabricated component 70, tighten the bolt 21, and then compare the length of the steel bar 72 with the length of the rear end of the detection rod 7. Use tools to cut off the excess length of the steel bar 72. At this time, the length of the steel bar 72 is consistent with the depth of the positioning hole 71, so that the prefabricated component 70 can be assembled later.

[0040] The fifth step is to detect the depth of the positioning hole 71 of the second prefabricated component 70: loosen bolt 1 21, push the slider 2 forward to the front end of the guide rail 1, drive the slide rail 3, the positioning plate 4 and the detection rod 7 to move forward, and the slide rail 3 slides downward, loosen bolt 2 82, so that the rubber block 83 is separated from the detection rod 7. With the same principle as the second step, detect the depth of the positioning hole 71 of the second prefabricated component 70. In this way, the depth of all positioning holes 71 can be detected at the same time, and the length of the steel bar 72 and the depth of the corresponding positioning hole 71 can be quickly compared, thereby improving the efficiency of positioning detection.

[0041] When the positioning detector of the assembled precision steel bar 72 is not needed, the middle section 102 and the rear section 103 of the guide rail 1 are manually pushed to make the guide rail 1 become Figure 3 The guide rail 1 is in the retracted state shown in the figure, and the insertion rod 122 is pulled, the reset spring is stretched, and after the insertion rod 122 is aligned with the insertion hole 123, the insertion rod 122 is released, the reset spring is reset, and the insertion rod 122 is inserted into the insertion hole 123. The rear section 103 of the guide rail 1 is limited by the insertion rod 122, so that the guide rail 1 remains in the retracted state, thereby facilitating the transportation and placement of the device; when the device needs to be used again, the insertion rod 122 is pulled to make the insertion rod 122 leave the insertion hole 123, and the guide rail 1 can be unfolded again. Figure 2 Status shown.

[0042] Example 2: Based on Example 1, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig.10 and Fig.11The positioning detector of the assembled precision-built steel bars also includes a slide plate 131, a roller 133 and a cylinder 135. The guide rail 1 is provided with a slide plate 131 that slides on the Y-axis. The slide plate 131 is provided with a plane 130 and an inclined extrusion surface 132. The top of the slide rail 3 is rotatably connected with a roller 133 that contacts the extrusion surface 132. The lower part of the slide plate 131 is provided with a long hole 134 along the Y-axis, and the middle part of the slider 2 is provided with a cylinder 135 located in the long hole 134.

[0043] Initially, the cylinder 135 is located at the rearmost end of the long hole 134. When the depth detection of the positioning hole 71 of the prefabricated component 70 is completed, the slide plate 131 is pulled forward, and the slide plate 131 drives the cylinder 135 to move forward, so that the slider 2, the slide rail 3, the positioning plate 4, the connecting column 5, the fixing plate 6 and the detection rod 7 move forward as a whole, so that the detection rod 7 leaves the positioning hole 71 of the prefabricated component 70, and then the positioning detector of the assembled fine steel bar 72 is installed on the next prefabricated component 70, and the slider 2 is pressed by one hand and the slide plate 131 is pushed backward by the other hand, and the backward slide plate 131 squeezes the roller 133 through the extrusion surface 132. The roller 133 moves upward along the extrusion surface 132 to the plane 130, driving the slide rail 3, the positioning plate 4, the connecting column 5, the fixing plate 6 and the detection rod 7 to rise as a whole, so that the detection rod 7 is higher than the top surface of the prefabricated component 70. At this time, the protrusion 31 is located at the front end of the long hole 134; the slider 2 is released, and the slide plate 131 is pushed backward. The slide plate 131 drives the cylinder 135 to move backward, so that the slider 2, the slide rail 3, the positioning plate 4, the connecting column 5, the fixing plate 6 and the detection rod 7 move backward as a whole, and the length of the steel bar 72 of the prefabricated component 70 can be compared. In this way, the height position of the slide rail 3 can be maintained, and the operation is more convenient and labor-saving.

[0044] refer to Figure 2 , Figure 3 , Figure 4 and Fig.12 The positioning detector for the assembled precision-built steel bars also includes a fixed block 141 and a clamping rod 142. The fixed block 141 is welded to the right side of the front section 101 of the guide rail 1. The fixed block 141 is provided with a clamping rod 142 that slides up and down. A compression spring is fixedly connected between the clamping rod 142 and the fixed block 141. A hook-shaped portion 143 with an inclined surface is provided at the rear end of the clamping rod 142. A clamping groove 144 that cooperates with the hook-shaped portion 143 is opened on the right part of the slider 2.

[0045] When the slide plate 131 is pulled forward to drive the slider 2 to move forward, the slider 2 will squeeze the inclined surface of the hook portion 143, causing the clamping rod 142 to slide downward, and the compression spring will be compressed. When the hook portion 143 is located in the clamping groove 144, the compression spring will recover, and the clamping rod 142 will rise. The shape of the clamping groove 144 is as shown in FIG. Fig.12As shown, the hook portion 143 is inserted into the slot 144, thereby automatically fixing the position of the slider 2 to prevent the slider 2 from sliding freely. In the process of installing the positioning detector of the assembled precision-built steel bar 72 on the next prefabricated component 70, the prefabricated component 70 is prevented from squeezing the end of the detection rod 7. Then, the slide plate 131 is pushed backward to squeeze the roller 133 upward, and finally, the clamping rod 142 is pressed, and the slide plate 131 is pushed backward to make the hook portion 143 leave the slot 144, so that the slider 2 can be moved to the rear section 103 to compare the length of the steel bar 72.

[0046] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
