Description

Technical Field

[0001] The invention relates to the technical field of electric poles, in particular to a novel method for manufacturing cement electric poles. Background Art

[0002] Telephone poles, as the name suggests, are poles used to hold electric wires. Found in rural areas, fields, roads, and streets, they were a crucial piece of infrastructure in early China. Later, with the development of steel and reinforced concrete and technological advancements, these two materials largely replaced wood.

[0003] The existing line installation conventionally adopts the method of fixing crosspieces on cement poles and fixing crosspieces between adjacent cement poles through clamps to install lines. When the cement poles expand or contract due to changes in the external temperature, the clamp-type fixed crosspieces will tightly wrap the side walls of the poles, making the wrapped parts on the poles unable to expand or contract with changes in temperature, making the side walls of the poles susceptible to damage, resulting in reduced strength of the poles and shortened service life. At the same time, in this type of construction and installation, the line direction fixed by the clamps is difficult to adjust in the reverse direction, and the line removal and laying will also deviate. The cement poles are inconvenient to carry, which will cause some damage to the finished products during transportation, affecting the appearance, and making it impossible to achieve quick installation. The loss during use increases the cost of use to a certain extent. Summary of the Invention

[0004] The purpose of the present invention is to address the shortcomings of the existing technology and provide a new method for manufacturing cement utility poles. The structural innovation in the design realizes rapid disassembly and assembly, greatly improves work efficiency, and effectively shortens the construction period under the premise of improving quality.

[0005] The technical solution of the present invention is: a new method for manufacturing cement utility poles, comprising the following steps:

[0006] Step 1: Preparation before production: prepare the structural parts of the cement pole. The structural parts of the cement pole are specifically a cement casting layer composed of mixed cement, multiple reinforcing steel bars, five disc-shaped prefabricated plates and five fixed circular frames;

[0007] Step 2: Pre-molding processing: Place the fixed circular frame on one end of the multiple reinforcement steel bars, then weld the multiple reinforcement steel bars to the inner wall of the fixed circular frame at equal distances around the circumference, position the multiple reinforcement steel bars, and then put the remaining fixed circular frame on the side walls of the multiple reinforcement steel bars at predetermined positions and weld them together with the reinforcement steel bars. Sixteen fixing holes are opened at equal distances around the side walls of the prefabricated panel.

[0008] Step 3: Forming the electric pole: Place the finished product from step 2 in the electric pole forming mold, then pour the cement prepared in step 1 into the mold and wait for the cement to solidify and form. After the electric pole is formed, weld the five prefabricated panels to the outer walls of the five fixed circular frames to obtain a cement electric pole.

[0009] Step 4: Installation of the crossbar. In order to facilitate the placement of wires on the side walls of the cement poles, a wire installation structure needs to be installed on the side walls of the cement poles before the poles are installed outdoors. The wire installation structure consists of a fixed crossbar and fixing bolts. The fixed crossbar is placed on the side walls of the prefabricated panels at a predetermined angle, and the holes on the fixed crossbar are aligned with the fixing holes. The fixed crossbar is fixed to the prefabricated panels by fixing bolts.

[0010] Step 5: For outdoor installation, first place the transformer box installation structure on the ground for standby use. The transformer box installation structure consists of the transformer box body and the installation cross bar. Then, pour a base with cement on the ground at the predetermined position. Before the base solidifies, place two cement poles inside the base to firmly fix the cement poles and the base together. Then, fix the installation cross bar on the top wall of the prefabricated plate near the bottom of the two cement poles. Finally, fix the transformer box body on the top wall of the two installation cross bars.

[0011] Preferably, the structural parts of the cement electric pole further include a plurality of reinforcement strips, and the plurality of reinforcement strips are respectively welded to the ends of the side walls of the plurality of reinforcement steel bars away from the fixed circular frame.

[0012] Preferably, the prefabricated panel may also be in an elliptical shape, and an adjustment structure and a reinforcement structure may be provided inside the cement pole.

[0013] Preferably, the structural parts of the adjustment structure are specifically an upper wrapping frame, an adjustment slide groove, a lower wrapping frame, an adjustment slider, a rotation groove and a rotation frame;

[0014] The structural components of the reinforcement structure are specifically positioning slots, adjustment slots, supporting arc plates, fixing blocks, connecting screw frames, stabilizing blocks and positioning blocks.

[0015] Preferably, the rotating groove is opened on the outer wall of the fixed hole, and the rotating groove is a "T"-shaped annular groove. The rotating frame is slidably connected to the inside of the rotating groove, and then the prefabricated plate is put on the outer wall of the fixed circular frame, and the outer wall of the rotating groove is welded together with the inner wall of the prefabricated plate.

[0016] Preferably, the positioning slots are equidistantly arranged on the outer wall of the cement casting layer, and the positioning slots are located at the bottom ends of adjacent prefabricated panels. The fixed blocks are fixedly mounted on the side wall of the supporting arc plate close to the cement casting layer, and the connecting screw frame is fixedly mounted on the side wall of the supporting arc plate away from the cement casting layer, and the connecting screw frame is threadedly connected to the approaching fixing bolts.

[0017] Preferably, the upper wrapping frame is fixedly mounted on the top wall of the prefabricated panel, and the inner side walls of the upper wrapping frame are aligned with the inner side walls of the prefabricated panel, the adjustment slot is opened on the bottom wall of the prefabricated panel, the top end of the lower wrapping frame passes through the bottom wall of the prefabricated panel and extends to the inside of the adjustment slot, the adjustment slider is slidably connected to the inside of the adjustment slot, and the adjustment slider is fixedly connected to the side wall of the lower wrapping frame.

[0018] Preferably, the adjustment slot is opened on the top wall surface inside the positioning slot, the top end of the adjustment slot is inside the lower wrapping frame, the positioning block is fixed on the top wall surface of the stabilizing block, the lower wrapping frame is slid upward inside the adjustment slide slot to make the adjustment slot fully connected with the outside, and then the stabilizing block is inserted into the inside of the blank positioning slot, the positioning block is inserted into the inside of the adjustment slot along with the stabilizing block, and then the lower wrapping frame is loosened to make the inner side wall of the lower wrapping frame fit with the side wall of the positioning block, and the stabilizing block and the positioning block are fixed inside the positioning slot and the adjustment slot.

[0019] The present invention provides a novel cement utility pole manufacturing method through improvements, which has the following improvements and advantages compared with the prior art:

[0020] First, the present invention welds a fixed circular frame to the side wall of the reinforced steel bar during the casting of the utility pole, and then welds an upper and lower wrapping frame to the outer side wall of the fixed circular frame, so that the prefabricated plate and the fixed circular frame become a whole, avoiding the use of a clamp-type fixing structure to squeeze the side wall of the cement casting layer, so that the cement casting layer expands or contracts under the influence of the external environment, causing the side wall of the cement casting layer to crack. Fixing bolts are installed through the sixteen fixing holes on the prefabricated circular plate, realizing free adjustment of the line direction, so that the line will not deviate when the line is removed and laid out; the structural innovation in the design realizes rapid disassembly and assembly, greatly improving work efficiency and effectively shortening the construction period under the premise of improving quality;

[0021] Second, the present invention fixes and installs a plurality of reinforcing bars on the side walls of the reinforcing steel bars, and wraps the reinforcing bars with cement. After the cement casting layer solidifies and takes shape, the contact area between the reinforcing steel bars and the cement casting layer becomes larger, making the connection between the reinforcing steel bars and the cement casting layer tighter, while improving the strength of the utility pole;

[0022] Thirdly, in the present invention, a maximum of two wire installation structures are usually installed on a utility pole. If the prefabricated plate is in the shape of a disk, after the wire installation structures are installed on the front and rear ends of the prefabricated plate, the left and right sides of the prefabricated plate cannot be used, resulting in a waste of materials. By setting the prefabricated plate in an elliptical shape, the wire installation structures are fixed on the front and rear ends of the top wall of the prefabricated plate, reducing the consumable materials on the left and right ends of the prefabricated plate, thereby reducing costs.

[0023] Fourthly, in the present invention, when the cement utility pole is installed on the base, the prefabricated plate on the cement utility pole may not be in the predetermined position due to external reasons, resulting in the wire installation structures on the two cement utility poles on the base not being parallel to each other when the wire installation structures are installed. By cooperating with the rotating groove and the rotating frame, the prefabricated plate is rotatably connected to the fixed circular frame. Therefore, after the cement utility pole is installed, the angle of the prefabricated plate can be adjusted, thereby improving the fault tolerance of the utility pole.

[0024] Fifthly, in the present invention, after the prefabricated panel is rotated to a predetermined angle, the fixing cross bar is installed on the side wall of the prefabricated panel by using the fixing bolts, and then the supporting arc panel is threadedly connected to the fixing bolts by using the connecting screw frame, so that the top wall surface of the connecting screw frame fits with the bottom of the prefabricated panel, and a certain force is applied to the side wall of the connecting screw frame to bend the supporting arc panel, and the fixing block is clamped into the interior of the positioning slot to position the prefabricated panel so that the prefabricated panel cannot rotate. At the same time, the reaction force of the supporting arc panel is utilized to make the end of the fixing block away from the cement casting layer lift the bottom end of the prefabricated panel upward, thereby supporting the end of the prefabricated panel away from the cement casting layer and ensuring the stability of the prefabricated panel.

[0025] Sixth: The present invention slides the lower wrapping frame upward inside the adjusting slot to make the adjusting slot completely connected with the outside, and then inserts the stabilizing block into the blank positioning slot. The positioning block is inserted into the adjusting slot along with the stabilizing block. When the blank positioning slots on the same plane are filled with the stabilizing block, the lower wrapping frame is released to make the inner side wall of the lower wrapping frame fit with the side wall of the positioning block, thereby fixing the stabilizing block and the positioning block inside the positioning slot and the adjusting slot, and filling the blank positioning slots and the adjusting slots on the cement casting layer with the stabilizing block and the positioning block, reinforcing the side walls of the cement casting layer, and avoiding the reduction in strength of the cement casting layer due to too many positioning slots.

[0037] The present invention is described in detail below, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] The present invention provides a novel method for manufacturing cement utility poles through improvements. The technical solution of the present invention is:

[0039] like Figure 1-Figure 3 As shown, a new method for manufacturing cement utility poles includes the following steps:

[0040] Step 1: Preparation before production: prepare the structural parts of the cement utility pole 3. The structural parts of the cement utility pole 3 specifically include a cement casting layer 31 composed of mixed cement, multiple reinforcing steel bars 32, five disc-shaped prefabricated plates 33 and five fixed circular frames 35;

[0041] Step 2: Pre-molding processing: Place the fixed circular frame 35 on one end of the multiple reinforcing steel bars 32, then weld the multiple reinforcing steel bars 32 to the inner side wall of the fixed circular frame 35 at equal distances around the circumference, position the multiple reinforcing steel bars 32, and then put the remaining fixed circular frames 35 on the side walls of the multiple reinforcing steel bars 32 at predetermined positions and weld them together with the reinforcing steel bars 32. Sixteen fixing holes 34 are opened at equal distances around the circumference of the side walls of the prefabricated plate 33;

[0042] Step 3: Forming the electric pole: Place the finished product from step 2 in the electric pole forming mold, then pour the cement prepared in step 1 into the mold and wait for the cement to solidify and form. After the electric pole is formed, weld five prefabricated panels 33 to the outer walls of the five fixed circular frames 35 to obtain the cement electric pole 3;

[0043] Step 4: Installation of the crossbar. To facilitate the placement of wires on the side wall of the cement pole 3, a wire mounting structure 4 needs to be installed on the side wall of the cement pole 3 before the cement pole 3 is installed outdoors. The wire mounting structure 4 consists of a fixed crossbar 41 and a fixing bolt 42. The fixed crossbar 41 is placed on the side wall of the prefabricated panel 33 at a predetermined angle, so that the hole on the fixed crossbar 41 is aligned with the fixing hole 34. The fixed crossbar 41 is fixedly connected to the prefabricated panel 33 by the fixing bolt 42.

[0044] Step 5: Outdoor installation. First, place the transformer box mounting structure 2 on the ground for standby use. The transformer box mounting structure 2 consists of a transformer box body 21 and a mounting cross bar 22. Then, cast a base 1 with cement on the ground at a predetermined position. Before the base 1 solidifies, place two cement poles 3 inside the base 1 so that the cement poles 3 and the base 1 are firmly fixed together. Then, fix the mounting cross bar 22 on the top wall of the prefabricated plate 33 near the bottom of the two cement poles 3. Finally, fix the transformer box body 21 on the top wall of the two mounting cross bars 22.

[0045] The working principle of the present invention is as follows: when casting the electric pole, by welding the fixed circular frame 35 to the side wall of the reinforcing steel bar 32, and then welding the upper and lower wrapping frames 53 to the outer side wall of the fixed circular frame 35, the prefabricated plate 33 and the fixed circular frame 35 become a whole, avoiding the use of a clamp-type fixed structure to squeeze the side wall of the cement casting layer 31, so that the cement casting layer 31 expands or contracts under the influence of the external environment, causing the side wall of the cement casting layer 31 to crack, and installing the fixing bolts 42 through the sixteen fixing holes 34 on the prefabricated circular plate, realizing free adjustment of the line direction, so that there will be no deviation when the line is removed and laid out; the structural innovation in the design realizes rapid disassembly and assembly, greatly improves work efficiency, and effectively shortens the construction period under the premise of improving quality.

[0046] Example 2:

[0047] like Figure 1-Figure 4 As shown, a new method for manufacturing cement utility poles includes the following steps:

[0048] Step 1: Preparation before production: prepare the structural parts of the cement utility pole 3. The structural parts of the cement utility pole 3 specifically include a cement casting layer 31 composed of mixed cement, multiple reinforcing steel bars 32, five disc-shaped prefabricated plates 33, five fixed circular frames 35 and multiple reinforcement strips 36;

[0049] Step 2: Pre-molding processing: Place the fixed circular frame 35 on one end of the multiple reinforcing steel bars 32, then weld the multiple reinforcing steel bars 32 to the inner side wall of the fixed circular frame 35 at equal distances around the circumference, position the multiple reinforcing steel bars 32, and then put the remaining fixed circular frame 35 on the side wall of the multiple reinforcing steel bars 32 at a predetermined position and weld them together with the reinforcing steel bars 32, weld multiple reinforcing strips 36 to the end of the side wall of the multiple reinforcing steel bars 32 away from the fixed circular frame 35, and open sixteen fixing holes 34 at equal distances around the circumference on the side wall of the prefabricated plate 33;

[0050] Step 3: Forming the electric pole: Place the finished product from step 2 in the electric pole forming mold, then pour the cement prepared in step 1 into the mold. The cement will wrap the side walls of the reinforcement strips 36. Wait for the cement to solidify and form. After the electric pole is formed, weld the five prefabricated panels 33 to the outer walls of the five fixed circular frames 35 to obtain the cement electric pole 3.

[0051] Step 4: Installation of the crossbar. To facilitate the placement of wires on the side wall of the cement pole 3, a wire mounting structure 4 needs to be installed on the side wall of the cement pole 3 before the cement pole 3 is installed outdoors. The wire mounting structure 4 consists of a fixed crossbar 41 and a fixing bolt 42. The fixed crossbar 41 is placed on the side wall of the prefabricated panel 33 at a predetermined angle, so that the hole on the fixed crossbar 41 is aligned with the fixing hole 34. The fixed crossbar 41 is fixedly connected to the prefabricated panel 33 by the fixing bolt 42.

[0052] Step 5: Outdoor installation. First, place the transformer box mounting structure 2 on the ground for standby use. The transformer box mounting structure 2 consists of a transformer box body 21 and a mounting cross bar 22. Then, cast a base 1 with cement on the ground at a predetermined position. Before the base 1 solidifies, place two cement poles 3 inside the base 1 so that the cement poles 3 and the base 1 are firmly fixed together. Then, fix the mounting cross bar 22 on the top wall of the prefabricated plate 33 near the bottom of the two cement poles 3. Finally, fix the transformer box body 21 on the top wall of the two mounting cross bars 22.

[0053] The working principle of the present invention is as follows: by fixing a plurality of reinforcing bars 36 on the side walls of the reinforcing steel bars 32 and wrapping the reinforcing bars 36 with cement, after the cement casting layer 31 solidifies and takes shape, the contact area between the reinforcing steel bars 32 and the cement casting layer 31 becomes larger, making the connection between the reinforcing steel bars 32 and the cement casting layer 31 tighter, while improving the strength of the utility pole.

[0054] Example 3:

[0055] like Figure 5-Figure 8 As shown, a new method for manufacturing cement utility poles includes the following steps:

[0056] Step 1: Preparation before production: prepare the structural parts of the cement utility pole 3. The structural parts of the cement utility pole 3 specifically include a cement casting layer 31 composed of mixed cement, multiple reinforcing steel bars 32, five oval prefabricated panels 33, five fixed circular frames 35 and multiple reinforcing strips 36;

[0057] Step 2: Processing before forming: Place the fixed circular frame 35 on one end of the multiple reinforcing steel bars 32, then weld the multiple reinforcing steel bars 32 to the inner side wall of the fixed circular frame 35 at equal distances around the circumference, position the multiple reinforcing steel bars 32, and then put the remaining fixed circular frame 35 on the side wall of the multiple reinforcing steel bars 32 at a predetermined position and weld them together with the reinforcing steel bars 32, weld multiple reinforcing strips 36 on the end of the side wall of the multiple reinforcing steel bars 32 away from the fixed circular frame 35, and open three fixing holes 34 at the front and rear ends of the top wall of the prefabricated panel 33;

[0058] Step 3: Forming the electric pole: Place the finished product from step 2 in an electric pole forming mold, then pour the cement prepared in step 1 into the mold. The cement will wrap the side walls of the reinforcement strip 36. Wait for the cement to solidify and form the electric pole. After the electric pole is formed, a cement electric pole 3 is obtained.

[0059] Step 4: Adjust the position of the cement pole 3. Prepare the structural parts of the adjustment structure 5. The structural parts of the adjustment structure 5 are specifically the upper wrapping frame 51, the adjustment chute 52, the lower wrapping frame 53, the adjustment slider 54, the rotating groove 55 and the rotating frame 56. The rotating groove 55 is provided on the outer wall of the fixing hole 34. The rotating groove 55 is a T-shaped annular groove. The rotating frame 56 is slidably connected to the inside of the rotating groove 55. Then, the prefabricated panel 33 is sleeved on the outer wall of the fixed circular frame 35, and the outer wall of the rotating groove 55 is welded to the inner wall of the prefabricated panel 33.

[0060] Step 5: Define the position of the cement utility pole 3 and prepare the structural components of the reinforcement structure 6. The structural components of the reinforcement structure 6 are specifically the positioning card slot 61, the adjustment card slot 62, the support arc plate 63, the fixing card block 64, the connecting screw frame 65, the stabilizing card block 66 and the positioning card block 67. The positioning card slots 61 are equidistantly arranged on the outer wall of the cement casting layer 31, and the positioning card slots 61 are located at the bottom end of the adjacent prefabricated plate 33. The fixing card block 64 is fixedly installed on the side wall of the support arc plate 63 close to the cement casting layer 31. The connecting screw frame 65 is fixedly installed on the side wall of the support arc plate 63 away from the cement casting layer 31, and the connecting screw frame 65 is threadedly connected to the adjacent fixing bolts 42.

[0061] Step 6: Reinforce the upper side wall of the cement pole 3, fix the upper wrapping frame 51 on the top wall of the prefabricated panel 33, and align the inner side wall of the upper wrapping frame 51 with the inner side wall of the prefabricated panel 33, open the adjustment slot 52 on the bottom wall of the prefabricated panel 33, and the top of the lower wrapping frame 53 passes through the bottom wall of the prefabricated panel 33 and extends to the inside of the adjustment slot 52. The adjustment slider 54 is slidably connected to the inside of the adjustment slot 52, and the adjustment slider 54 is fixedly connected to the side wall of the lower wrapping frame 53. The adjustment slot 62 is opened on the top wall inside the positioning slot 61, and the top of the adjustment slot 62 is at the bottom of the lower wrapping frame 53. The interior of the packaging frame 53 is fixed to the top wall of the stabilizing block 66. The lower wrapping frame 53 is slid upward inside the adjusting slot 52 to make the adjusting slot 62 completely connected with the outside. Then the stabilizing block 66 is inserted into the blank positioning slot 61. The positioning block 67 is inserted into the adjusting slot 62 along with the stabilizing block 66. When the blank positioning slot 61 on the same plane is filled with the stabilizing block 66, the lower wrapping frame 53 is released to make the inner side wall of the lower wrapping frame 53 fit with the side wall of the positioning block 67, thereby fixing the stabilizing block 66 and the positioning block 67 inside the positioning slot 61 and the adjusting slot 62.

[0062] Step 7: Installation of the crossbar. To facilitate the placement of wires on the side wall of the cement pole 3, a wire mounting structure 4 needs to be installed on the side wall of the cement pole 3 before the cement pole 3 is installed outdoors. The wire mounting structure 4 consists of a fixed crossbar 41 and a fixing bolt 42. The fixed crossbar 41 is placed on the side wall of the prefabricated panel 33 at a predetermined angle, so that the hole on the fixed crossbar 41 is aligned with the fixing hole 34. The fixed crossbar 41 is fixedly connected to the prefabricated panel 33 by the fixing bolt 42.

[0063] Step 8: For outdoor installation, first place the transformer box mounting structure 2 on the ground for standby use. The transformer box mounting structure 2 consists of a transformer box body 21 and a mounting cross bar 22. Then, cast a base 1 with cement on the ground at a predetermined position. Before the base 1 solidifies, place two cement poles 3 inside the base 1 so that the cement poles 3 and the base 1 are firmly fixed together. Then, fix the mounting cross bar 22 on the top wall of the prefabricated plate 33 near the bottom of the two cement poles 3. Finally, fix the transformer box body 21 on the top wall of the two mounting cross bars 22.

[0064] The working principle of the present invention is as follows: Usually, a maximum of two wire installation structures 4 are installed on a utility pole. If the prefabricated plate 33 is disc-shaped, after the wire installation structures 4 are installed on the front and rear ends of the prefabricated plate 33, the left and right sides of the prefabricated plate 33 cannot be used, resulting in material waste. By setting the prefabricated plate 33 into an elliptical shape, the wire installation structures 4 are fixed on the front and rear ends of the top wall of the prefabricated plate 33, reducing the consumable materials on the left and right ends of the prefabricated plate 33, thereby reducing costs.

[0065] When the cement utility pole 3 is installed on the base 1, the cement utility pole 3 may cause the prefabricated plate 33 on the cement utility pole 3 to be not in the predetermined position due to external reasons. As a result, when the wire mounting structures 4 are installed on the two cement utility poles 3 on the base 1, the wire mounting structures 4 on the two cement utility poles 3 are not in a parallel state with each other. The prefabricated plate 33 is rotatably connected to the fixed circular frame 35 by the mutual cooperation of the rotating groove 55 and the rotating frame 56. Therefore, after the cement utility pole 3 is installed, the angle of the prefabricated plate 33 can be adjusted, thereby improving the fault tolerance of the utility pole.

[0066] After the prefabricated panel 33 is rotated to a predetermined angle, the fixing cross bar 41 is installed on the side wall of the prefabricated panel 33 by using the fixing bolts 42, and then the supporting arc plate 63 is threadedly connected to the fixing bolts 42 by the connecting screw frame 65, so that the top wall surface of the connecting screw frame 65 fits with the bottom of the prefabricated panel 33, and a certain force is applied to the side wall of the connecting screw frame 65 to bend the supporting arc plate 63, so that the fixing block 64 is clamped into the inside of the positioning slot 61, and the position of the prefabricated panel 33 is positioned so that the prefabricated panel 33 cannot rotate. At the same time, the reaction force of the supporting arc plate 63 is used to make the end of the fixing block 64 away from the cement casting layer 31 lift the bottom end of the prefabricated panel 33 upward, thereby supporting the end of the prefabricated panel 33 away from the cement casting layer 31 and ensuring the stability of the prefabricated panel 33.

[0067] By sliding the lower wrapping frame 53 upward inside the adjusting slot 52, the adjusting slot 62 is completely connected with the outside, and then the stabilizing block 66 is inserted into the blank positioning slot 61, and the positioning block 67 is inserted into the adjusting slot 62 along with the stabilizing block 66. When the blank positioning slot 61 on the same plane is filled with the stabilizing block 66, the lower wrapping frame 53 is released, so that the inner side wall of the lower wrapping frame 53 fits with the side wall of the positioning block 67, thereby fixing the stabilizing block 66 and the positioning block 67 inside the positioning slot 61 and the adjusting slot 62, and using the stabilizing block 66 and the positioning block 67 to fill the blank positioning slot 61 and the adjusting slot 62 on the cement casting layer 31, the side wall of the cement casting layer 31 is reinforced to avoid the strength reduction of the cement casting layer 31 due to the opening of too many positioning slots 61.
