Description

Technical Field

[0001] The invention belongs to the technical field of civil engineering, and in particular relates to a pre-embedded sleeve positioning clamping device and a positioning clamping method. Background Art

[0002] The embedded sleeve is a sleeve-shaped embedded part used to be embedded in the concrete pipe segment. Some embedded sleeves are provided with T-shaped grooves, which are convenient for the use of T-shaped bolts to be inserted into the pipe segment after installation to play a connecting role. The existing embedded sleeves are positioned by plastic plug-type clamps during embedding. One end of the plastic plug-type clamp is inserted into the embedded sleeve, and the other end is inserted into the pipe segment mold, so that the embedded sleeve is fixed on the pipe segment mold, which belongs to the cantilever beam fixing method. This method of fixing the embedded sleeve with a plastic plug-type clamp is prone to overturning during the concrete pouring process, which is unreliable. The position between the poured pipe segment and the sleeve is uncertain, and the poured embedded sleeve is skewed and unsightly, resulting in the scrapping of the pipe segment. In addition, the plastic plug is a consumable, and the plastic part is easy to wear. The number of reuses is low, only 1 to 3 times, and the operation process is cumbersome and the cost is high, one yuan per piece.

[0040] The present invention is further illustrated below in conjunction with specific examples. The examples are implemented based on the technical solutions of the present invention. It should be understood that these examples are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the embedded sleeve 9 and the mold 8 (only a part of the mold 8 is shown in the figure) of this embodiment are used to form concrete segments after pouring concrete. The mold 8 is provided with a plurality of mold through holes 81 (only one is shown in the figure). The embedded sleeve 9 is placed at the position of the mold through hole 81 on the mold 8. When in use, concrete is poured on the mold 8 to wrap the embedded sleeve 9 as a whole. After the concrete solidifies, the mold is demoulded, and the embedded sleeve 9 is integrally connected with the concrete segment to form an embedded part.

[0042] like Figure 6 and Figure 7 As shown, the embedded sleeve 9 includes an anchor rod 91 and a working cylinder 92. The anchor rod 91 can improve the stability after embedding, so that the embedded sleeve 9 can effectively bear the load. The working cylinder 92 is a hollow cylindrical body. A working cavity is arranged in the working cylinder 92. Two protruding blocks 93 corresponding to the T-bolts are symmetrically arranged in the working cavity. The protruding blocks 93 are semi-cylindrical. The arc surfaces of the two protruding blocks 93 are connected to the inner wall of the working cylinder 92. The head of the T-bolt passes through the two protruding blocks 93. After the head of the T-bolt enters the top of the working cavity upward, it rotates 90° and then moves downward. The two protruding blocks 93 can block the head of the T-bolt, thereby limiting the downward movement of the T-bolt; two blocking blocks 931 are also arranged at the top of the protruding block 93. The two blocking blocks 931 are symmetrically arranged on both sides of the top of the protruding block 93. The two blocking blocks 931 are used to accommodate the head of the T-bolt. When the head of the T-bolt is located on the protruding block 93, the two blocking blocks 931 can limit the sliding of the head of the T-bolt, thereby making the T-bolt more stable.

[0043] like Fig. 9 , Fig.11 , Fig.15 , Fig.16 and Fig.17As shown, a pre-embedded sleeve positioning clamping device of the present embodiment includes a clamping jaw assembly, a second displacement assembly 2 and a first displacement assembly 1. The clamping jaw assembly is used to pass through the mold through hole 81. The clamping jaw assembly includes a first clamping jaw 3 and a second clamping jaw 4 that are symmetrically arranged. The first clamping jaw 3 includes a first working rod 31 and an L-shaped connecting rod. The second clamping jaw 4 includes a second working rod 41 and an L-shaped connecting rod. The first working rod 31 and the second working rod 41 are used to extend into the pre-embedded sleeve 9. The top ends of the first working rod 31 and the second working rod 41 are respectively provided with working hooks 5. The first displacement assembly 1 includes a first base 11, a first driving member 12 and a first slide 13. The first base 11 is rectangular. The first driving member 12 is arranged on the first base 11. The first driving member 12 adopts an existing cylinder. The first slide 13 slides up and down along the Y-axis direction on the first base 11. The first slide 13 is connected to the piston rod of the first driving member 12, so that the first driving member 12 can drive the first slide 13 to slide up or down. The second displacement assembly 2 is connected to the clamping jaw assembly and drives the clamping jaw assembly to move along the X-axis direction. The second displacement assembly 2 includes a second base 21, a second driving member 22, a first slide 23 and a second slide 24. The second base 21 is connected to the first slide 13. The second driving member 22 is arranged in the second base 21. The second driving member 22 adopts an existing two-way cylinder (an electric cylinder can also be used) and is provided with left and right piston rods. When working, the left and right piston rods extend outward synchronously. The first slide 23 and the second slide 24 are symmetrically arranged on the second base 21 and are slidably connected to the second base 21. A slide 23 is connected to the piston rod on the left side of the second driving member 22, and a second slide 24 is connected to the piston rod on the right side of the second driving member 22. When the second driving member 22 is working, the first slide 23 and the second slide 24 are driven to move toward or away from each other along the X-axis direction. The first clamp 3 is connected to the first slide 23, and the second clamp 4 is connected to the second slide 24. Thus, under the drive of the second driving member 22, the first clamp 3 and the second clamp 4 move toward or away from each other along the X-axis direction. Both clamps are detachably connected to the slide by bolts, so that clamps of different sizes can be replaced according to the size of the embedded sleeve 9. When the first clamp 3 and the second clamp 4 move away from each other, the first working rod 31 and the second working rod 41 move toward the protruding block 93 until they are pressed against the side wall of the protruding block 93, thereby positioning the embedded sleeve 9. The position of the working hook 5 corresponds to the protruding block 93. When the first working rod 31 and the second working rod 41 are pressed against the side wall of the protruding block 93, the first driving member 12 of the first displacement assembly 1 works, and the first slide 13 drives the second displacement assembly 2 and the clamping jaw assembly to move downward along the Y-axis direction. The working hook 5 is pressed against the protruding block 93, thereby pressing the embedded sleeve 9 onto the mold 8.

[0044] like Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13As shown, the first working rod 31 and the second working rod 41 both include a first abutting portion 61 corresponding to the side wall of the protruding block 93. The first abutting portion 61 is located near the upper end of the two working rods. When the clamping jaw assembly is inserted from the center of the mold through hole 81, the first working rod 31 and the second working rod 41 are located at the center of the working cavity of the working cylinder 92. The distance from the first abutting portion 61 to the side wall of the protruding block 93 is D 1 The first working rod 31 and the second working rod 41 are both provided with a stopper 62 at positions corresponding to the mold through hole 81. The mold through hole 81 is a circular hole. The stopper 62 is connected to the lower end side of the two working rods. The distance from the outer side of the stopper 62 to the inner wall of the mold through hole 81 is D 2 When the first clamping jaw 3 and the second clamping jaw 4 face away from each other along the X-axis direction, the limit block 62 moves toward the inner wall of the mold through hole 81, and the limit block 62 passes D 2 After the distance, it contacts the inner wall of the mold through hole 81, D 2 ≥D 1 , and D 2 -D 1 ≤1mm, in this embodiment, D 2 =D 1 , since the personnel place the entire positioning clamping device under the mold 8 and the clamping assembly cannot ensure that the clamping assembly is kept at the center position of the mold through hole 81 when passing through the mold through hole 81, and the personnel place the embedded sleeve 9 at the position of the mold through hole 81 and cannot ensure that the central axis of the embedded sleeve 9 is in the same straight line with the central axis of the mold through hole 81, this embodiment provides a limit block 62, and D 2 =D 1 When the limit block 62 is driven by the first working rod 31 and the second working rod 41 to move toward the inner wall of the mold through hole 81, the limit block 62 can ensure that the clamping jaw assembly is in the center position of the mold through hole 81 after contacting the inner wall of the mold through hole 81. If the limit block 62 on one side contacts the inner wall of the mold through hole 81 first, a reaction force will be given to the entire positioning and clamping device, thereby adjusting the position of the positioning and clamping device so that the clamping jaw assembly is in the center position. At this time, the two first clamping portions 61 are pressed against the side walls of the two protruding blocks 93 to ensure that the embedded sleeve 9 is in the center position. If the original position of the embedded sleeve 9 is offset, the first clamping portion 61 on one side will first contact the corresponding side wall of the protruding block 93. Under the pushing action of the first clamping portion 61, the position of the embedded sleeve 9 will follow and move until it reaches the center position. At this time, the center axis of the embedded sleeve 9 is in the same straight line as the center axis of the mold through hole 81, and the embedded sleeve 9 is concentric with the mold through hole 81, which ensures the position accuracy of the embedded sleeve 9. Since there may be errors in the limit block 62 and the mold through hole 81 during processing, D 2 >D 1 , but D is not allowed 2 <D 1 , if D2 <D 1 This means that the stopper block 62 has already contacted the inner wall of the mold through hole 81 before the first abutting portion 61 contacts the side wall of the protruding block 93. At this time, the first working rod 31 and the second working rod 41 cannot position the embedded sleeve 9, and D 2 >D 1 When the first working rod 31 and the second working rod 41 can position the embedded sleeve 9, there is only an error in the positioning of the embedded sleeve 9. 2 -D 1 ≤1mm. In actual use, when the error is within 1mm, the offset position of the embedded sleeve 9 is acceptable and does not affect the subsequent use of the concrete segment.

[0045] like Fig.13 As shown, the limit block 62 is detachably connected to the first working rod 31 and the second working rod 41. The limit block 62 is a rectangular block. The inner side of the limit block 62 is provided with a first threaded hole 621. The first working rod 31 and the second working rod 41 are both provided with a countersunk through hole 311 corresponding to the first threaded hole 621. The countersunk through hole 311 is provided with a countersunk bolt 622. The countersunk bolt 622 corresponds to the first threaded hole 621. The limit block 62 is detachably connected to the two working rods through the countersunk bolt 622. When connected, the countersunk bolt 622 does not affect the fit of the two working rods. The limit block 62 can be replaced to adapt to mold through holes 81 of different apertures.

[0046] like Fig.14 As shown, another implementation of the limit block 62 is different from the first implementation of the limit block 62 in that the outer side surface of the limit block 62 is an arc surface corresponding to the inner wall of the mold through hole 81, so that the limit block 62 is in closer contact with the inner wall of the mold through hole 81.

[0047] like Figure 8 As shown, a sealing ring 99 is provided between the embedded sleeve 9 and the mold 8. The sealing ring 99 is an annular sealing ring. When the embedded sleeve 9 is clamped, the lower end of the working cylinder 92 presses the sealing ring 99 against the mold 8. When pouring concrete, the sealing ring 99 can prevent the concrete from entering the working cylinder 92. After demoulding, the sealing ring 99 can be recycled.

[0048] like Figure 1 , Figure 7 , Figure 8 , Fig. 9 and Fig.15 As shown, this embodiment also provides a pre-embedded sleeve positioning and clamping method, using the above-mentioned pre-embedded sleeve positioning and clamping device, comprising the following steps:

[0049] Step 1: Place the embedded sleeve 9 on the mold 8 so that the position of the embedded sleeve 9 corresponds to the position of the mold through hole 81 , and place the sealing ring 99 between the embedded sleeve 9 and the mold 8 .

[0050] Step 2: Place the first displacement assembly 1 against the back of the mold 8 , the upper end of the first base 11 against the back of the mold 8 , the clamping jaw assembly passes through the mold through hole 81 , and the first working rod 31 and the second working rod 41 extend into the working cavity of the embedded sleeve 9 .

[0051] Step 3, the second driving member 22 of the second displacement assembly 2 works, driving the first slide 23 and the second slide 24 to move in opposite directions along the X-axis direction, the first clamping jaw 3 and the second clamping jaw 4 to move in opposite directions along the X-axis direction, and the first clamping portion 61 of the first working rod 31 and the second working rod 41 is pressed against the side wall of the protruding block 93 of the embedded sleeve 9; when the first clamping jaw 3 and the second clamping jaw 4 move in opposite directions along the X-axis direction, the upper limit blocks 62 of the first working rod 31 and the second working rod 41 move toward the inner wall of the mold through hole 81, and the two first clamping portions 61 move toward the side wall of the protruding block 93 so that the axis of the embedded sleeve 9 is in the same straight line as the axis of the mold through hole 81, thereby completing the positioning of the embedded sleeve 9.

[0052] Step 4, the first driving member 12 of the first displacement assembly 1 drives the second displacement assembly 2 and the clamping assembly to move downward along the Y-axis direction. The first displacement assembly 1 is against the back of the mold 8 and cannot move upward. The clamping assembly drives the working hook 5 to press on the protruding block 93 and press the embedded sleeve 9 on the mold, completing the clamping of the embedded sleeve 9.

[0053] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
