Description

Technical Field

[0001] This invention relates to the field of bridge engineering technology, and more specifically, to a steel wedge slope adjustment device in a cap beam support system. Background Technology

[0002] During bridge construction, the erection of the cap beam support system first requires the pouring of support columns, followed by the pouring of the cap beam above the support columns. Before pouring the cap beam, the pouring mold must be installed. Before installation, construction workers calculate the reserved height of the mandrel on the support column based on the combined height data of the cap beam support system. Then, holes are pre-embedded in the support column. When constructing the cap beam, steel pins are inserted, and then steel boxes are fitted onto the steel pins. Finally, wedges are placed on the steel boxes to support the pouring mold, or jacks are placed on the steel boxes to support the pouring mold.

[0003] After the cap beam is poured, demolding is required. At this time, the jacks can be retracted to allow the casting mold under the cap beam to detach from the cap beam due to its own weight, thus completing the demolding. However, during the construction of the cap beam support system, the inclination angle of the cap beam will vary depending on the construction of different sections of the bridge. It is not only in a horizontal state, but when the cap beam is inclined, there is a contact area between the top of the jack and the casting mold, resulting in only line contact bearing. This can easily cause the casting mold to slip during demolding, leading to accidents. When construction workers use wedges to support the casting mold, different shaped wedges can be used for support according to the different inclination angles of the cap beam. Although the wedges can support the casting mold, they can only be knocked out during demolding. This process can cause the casting mold to fall too quickly, which can easily lead to accidents. Summary of the Invention

[0004] This invention provides a steel wedge slope adjustment device in a cap beam support system, which can overcome some or all of the defects of the prior art.

[0005] The steel wedge slope adjustment device in the cap beam support system according to the present invention includes: a device body, the device body including an upper wedge and a lower wedge with a longitudinal cross section of a right-angled trapezoid; the inclined surfaces of the upper wedge and the lower wedge are slidably engaged; an adjusting member is provided between the upper wedge and the lower wedge for pushing the upper wedge and the lower wedge to slide; the adjusting member includes a threaded steel bar with both ends passing through the upper wedge and the lower wedge respectively, and nuts that cooperate with the threaded steel bar are provided at both ends; a support plate for supporting the casting mold is provided at the end of the upper wedge away from the lower wedge, and an adjusting mechanism is provided at the support plate for adjusting the tilt angle of the support plate.

[0006] With this invention, after the bridge piers are installed, the construction workers install the cap beam template above the piers. Before installing the cap beam template, the construction workers ascend to the top of the piers via a ladder cage to insert steel pins, then fit a steel box onto the steel pins, and then place the main body of the device on the steel box. Then, the construction workers adjust the tilt angle of the support plate according to the required tilt angle of the cap beam so that the support plate is parallel to the bottom of the cap beam template.

[0007] When adjusting the support plate, the construction workers first pull one end of the support plate, causing the rotating column at the other end of the support plate to rotate along the hinge above the second connecting plate, thus tilting the support plate. Then, the construction workers insert the first bolt into the corresponding threaded hole, which is marked with a scale line corresponding to the tilt angle of the cap beam. The support block on the first bolt extends into the installation groove. After that, the construction workers release the support plate, and the inclined plate below the support plate presses on the support block on the first bolt. The support block supports the support plate, thus maintaining the tilt angle of the support plate. This ensures that the support plate can completely fit the contact surface below the cap beam formwork, preventing any gaps between the support plate and the cap beam formwork. This would prevent the casting mold from slipping during demolding, which could lead to accidents.

[0008] After the support block angle is adjusted, the construction workers rotate the nuts on the threaded steel bar, causing the two nuts to push the upper and lower wedge blocks respectively. This allows the upper and lower wedge blocks to slide along their inclined surfaces, moving towards the center and pushing the upper wedge block upwards. The upward movement of the upper wedge block causes the adjusted support plate to move upwards, eventually pressing against the bottom of the cap beam formwork. This allows the construction workers to easily adjust the height of the main body of the device to ensure it is firmly pressed against the bottom of the cap beam formwork. After the cap beam is poured, simply loosen the two nuts to separate the upper and lower wedge blocks, allowing the support plate to detach from the cap beam formwork. At this point, the cap beam formwork will detach from the cap beam along with the support plate, making it easy for the construction workers to dismantle the cap beam formwork.

[0009] Preferably, the upper wedge includes a first connecting plate and a second connecting plate arranged in parallel; the upper ends of the first connecting plate and the second connecting plate are provided with a third connecting plate for connecting the first connecting plate and the second connecting plate, and the lower ends of the first connecting plate and the second connecting plate are provided with an inclined first inclined plate that connects the first connecting plate and the second connecting plate; the first connecting plate is provided with a first strip hole arranged along the length direction of the first connecting plate; the first inclined plate is provided with a second strip hole arranged along the length direction of the first inclined plate; the first strip hole and the second strip hole are for threaded steel bars to pass through;

[0010] The lower wedge includes a fourth connecting plate and a fifth connecting plate arranged in parallel; a sixth connecting plate is provided at one end of the fourth connecting plate and the fifth connecting plate for connecting the fourth connecting plate and the fifth connecting plate; a second inclined plate is provided at the other end of the fourth connecting plate and the fifth connecting plate; a third strip hole is provided at the fourth connecting plate along the length direction of the fourth connecting plate, and a fourth strip hole is provided at the second inclined plate along the length direction of the second inclined plate; the third strip hole and the fourth strip hole are for threaded steel bars to pass through.

[0011] With this invention, when the construction personnel adjust the movement of the upper and lower wedges, the threaded steel slides along the first, second, third, and fourth strip holes. The first, second, third, and fourth strip holes limit the movement of the threaded steel, thereby ensuring the stability of the upper and lower wedges during sliding.

[0012] Preferably, the third connecting plate has baffles perpendicular to the third connecting plate on both sides; the sidewall of the baffle has a plurality of threaded holes spaced apart along the length of the baffle; the plurality of threaded holes are gradually raised along the length of the baffle; the threaded holes have a first bolt and a second bolt passing through the threaded holes; one end of the first bolt passing through the threaded hole extends forward to form a support block; one end of the support plate is hinged to the second connecting plate; the end face of the support plate near the baffle has two inclined plates that press against the support block.

[0013] With this invention, since the threaded hole gradually rises along the length of the baffle, the tilt angle of the support block on the first bolt supporting the support plate is different when the first bolt is inserted into the threaded hole at different positions; thus, it is convenient for construction personnel to insert the first bolt into the corresponding threaded hole, so that the tilt angle of the support block supporting the support plate corresponds to the tilt angle of the cap beam.

[0014] Preferably, the end of the inclined plate that is hinged away from the support plate is provided with a seventh connecting plate for connecting the two inclined plates; the two baffles, the first connecting plate, the second connecting plate and the third connecting plate together constitute an installation groove for storing fine sand; the support plate is provided with an opening that communicates with the installation groove, and a cover plate is hinged to the opening for sealing the opening.

[0015] With this invention, after adjusting the support angle of the support plate, the construction personnel open the cover plate to open the sealing opening, and then pour fine sand into the opening. The fine sand enters the installation groove through the opening and fills the installation groove, thereby supporting the support plate and thus improving the support strength of the support plate. Before pouring in the fine sand, the construction personnel need to seal the remaining threaded holes with the second bolt.

[0016] Preferably, a push plate assembly is provided in the mounting groove to compact the fine sand in the mounting groove; the push plate assembly includes a first push plate disposed near one end of the support plate and disposed along the width direction of the mounting groove; a first groove disposed along the length direction of the first push plate is provided at the first push plate, a second push plate extending out of the first groove is disposed in the first groove, a second groove disposed along the length direction of the second push plate is disposed inside the second push plate; a third push plate extending out of the second groove is disposed in the second groove.

[0017] The first groove is provided with a first spring for pushing the second push plate toward the inclined plate; the second groove is provided with a second spring for pushing the third push plate toward the support plate; the two ends of the first push plate are provided with a pushing mechanism for pushing the first push plate to move along the length direction of the mounting groove.

[0018] In this invention, the first and second springs push the third and second push plates toward the inclined plate and the support plate, respectively, so that the upper ends of the third and second push plates contact the inclined plate and the support plate, respectively. This ensures that when the support plate rotates along the hinge, the third and second push plates remain against the inclined plate and the support plate. After the tilt angle of the support plate is adjusted and fine sand is poured into the mounting groove, the construction worker rotates the third bolt. At this time, the third bolt extends into the mounting groove and drives the connecting column and flange to rotate in the third limiting groove on the push block, pushing the push block to squeeze the mounting block. As the push block slides along the first inclined surface, it squeezes the mounting block, thereby pushing the first, third, and second push plates to squeeze the fine sand in the mounting groove, thus compacting the fine sand and keeping it in a compressed state against the support plate, thereby improving the support strength of the support plate.

[0019] The third and second push plates are arc-shaped at the ends that contact the inclined plate and the support plate, which can prevent the fine sand from leaking out from the contact point when the third and second push plates move and squeeze the fine sand.

[0020] Preferably, the pushing mechanism includes mounting blocks disposed on the side walls at both ends of the first push plate, and the mounting blocks are provided with a first inclined surface; a third bolt passing through the baffle is provided on the side of the baffle away from the mounting groove, and a push block cooperating with the first inclined surface is provided at one end of the third bolt passing through the baffle; the third bolt and the push block are rotatably connected.

[0021] With this invention, the construction worker can rotate the third bolt, which extends into the mounting groove and drives the connecting column and flange to rotate in the third limiting groove on the push block. This pushes the push block to squeeze the mounting block. As the push block slides along the first inclined surface, it squeezes the mounting block, thereby pushing the first push plate, the third push plate, and the second push plate to squeeze the fine sand in the mounting groove, thus compacting the fine sand and keeping it in a compressed state against the support plate, thereby improving the support strength of the support plate.

[0022] Preferably, the second connecting plate is provided with a guide post extending toward the first push plate, and the first push plate is provided with a sleeve into which the guide post extends; the sleeve is provided with a tension spring inside to pull the guide post and the first push plate to move toward each other.

[0023] With this invention, when the first push plate is pushed by the push block, the sleeve moves along the guide post, thereby improving the stability of the first push plate during movement. After the construction personnel remove the main body of the device, they open the support plate to pour out the fine sand in the installation groove, and then rotate the third bolt to pull the push block to move. During the process of the push block moving to the bottom of the first inclined surface, the tension spring will pull the first push plate to move, thereby completing the reset of the first push plate.

[0024] Preferably, a plurality of first reinforcing plates are provided between the first connecting plate, the first inclined plate and the third connecting plate; and a plurality of second reinforcing plates are provided between the fifth connecting plate, the sixth connecting plate and the fourth connecting plate.

[0025] Through this invention, the first reinforcing plate and the second reinforcing plate better improve the overall structural strength of the upper wedge and the lower wedge.

[0026] Preferably, the first connecting plate, the first inclined plate, the third connecting plate, and the first reinforcing plate together constitute the first limiting groove; the fifth connecting plate, the sixth connecting plate, the fourth connecting plate, and the second reinforcing plate together constitute the second limiting groove.

[0027] With this invention, when assembling the upper and lower wedges, construction workers can insert their fingers into the first and second limiting grooves, making it easier for them to pick up the upper and lower wedges.

[0028] Preferably, the upper sidewall of the fourth connecting plate is provided with a partition for blocking the upper wedge block.

[0029] Through this invention, the partition can block the upper wedge block, preventing it from detaching from the lower wedge block when it slides upward on the lower wedge block; at the same time, after the construction personnel release the upper wedge block from supporting the cap beam formwork, the partition can support the cap beam formwork after the upper wedge block moves down a certain distance.

[0044] To further understand the content of this invention, a detailed description of the invention is provided in conjunction with embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0045] Example 1

[0046] like Figure 1-14 As shown, this embodiment provides a steel wedge slope adjustment device in a cap beam support system, including a device body 100. The device body 100 includes an upper wedge 110 and a lower wedge 130 with a longitudinal cross-section of a right-angled trapezoid. The inclined surfaces of the upper wedge 110 and the lower wedge 130 are slidably engaged. An adjusting member 120 is provided between the upper wedge 110 and the lower wedge 130 for pushing the upper wedge 110 and the lower wedge 130 to slide. The adjusting member 120 includes a threaded steel bar 1201 with both ends passing through the upper wedge 110 and the lower wedge 130 respectively. Nuts 1202 that cooperate with the threaded steel bar 1201 are provided at both ends of the threaded steel bar 1201. A support plate 320 for supporting the casting mold is provided at the end of the upper wedge 110 away from the lower wedge 130. An adjusting mechanism is provided at the support plate 320 for adjusting the tilt angle of the support plate 320.

[0047] In this embodiment, after the construction workers have installed the pier 002 below the bridge, they install the cap beam template above the pier 002. Before installing the cap beam template 001, the construction workers rise to the top of the pier 002 through the ladder cage 003 to insert steel pins, and then put steel boxes on the steel pins. After that, the main body of the device 100 is placed on the steel box. Then, the construction workers start to adjust the tilt angle of the support plate 320 according to the required tilt angle of the cap beam so that the support plate 320 can be parallel to the bottom of the cap beam template 001.

[0048] When adjusting the support plate 320, the construction workers first pull one end of the support plate 320, causing the rotating column 305 at the other end of the support plate 320 to rotate along the hinge above the second connecting plate 490, thereby tilting the support plate 320. Then, the construction workers insert the first bolt 420 into the corresponding threaded hole 520, where the threaded hole 520 is marked with a scale line corresponding to the tilt angle of the cap beam. The support block 1001 on the first bolt 420 extends into the mounting groove 530. After that, the construction workers release the support plate 320, and the inclined plate 340 below the support plate 320 presses on the support block 1001 on the first bolt 420. The support block 1001 supports the support plate 320, thereby maintaining the tilt angle of the support plate 320. This ensures that the support plate 320 can completely fit the contact surface below the cap beam template 001, preventing the support plate 320 from coming loose from the contact area with the cap beam template 001, which could cause the casting mold to slip during demolding and lead to an accident.

[0049] After the angle of the support block 1001 is adjusted, the construction workers rotate the nuts 1202 on the threaded steel bar 1201, causing the two nuts 1202 on the threaded steel bar 1201 to push the upper wedge block 110 and the lower wedge block 130 respectively. This causes the upper wedge block 110 and the lower wedge block 130 to slide along the inclined surfaces on the upper wedge block 110 and the lower wedge block 130, thus moving them closer together. This pushes the upper wedge block 110 upward, which in turn moves the adjusted support plate 320 upward, eventually abutting against the bottom of the cap beam template 001. This allows the construction workers to easily adjust the height of the main body 100 of the device to ensure it is firmly against the bottom of the cap beam template 001. After the cap beam is poured, simply loosen the two nuts 1202 to separate the upper wedge block 110 and the lower wedge block 130, allowing the support plate 320 to detach from the cap beam template 001. At this time, the cap beam template 001 will detach from the cap beam along with the support plate 320, making it easy for the construction workers to remove the cap beam template 001.

[0050] In this embodiment, the upper wedge block 110 includes a first connecting plate 440 and a second connecting plate 490 arranged in parallel; the upper ends of the first connecting plate 440 and the second connecting plate 490 are provided with a third connecting plate 470 for connecting the first connecting plate 440 and the second connecting plate 490, and the lower ends of the first connecting plate 440 and the second connecting plate 490 are provided with an inclined first inclined plate 460 that connects the first connecting plate 440 and the second connecting plate 490; the first connecting plate 440 is provided with a first strip hole 430 arranged along the length direction of the first connecting plate 440; the first inclined plate 460 is provided with a second strip hole 220 arranged along the length direction of the first inclined plate 460; the first strip hole 430 and the second strip hole 220 allow the threaded steel bar 1201 to pass through;

[0051] The lower wedge block 130 includes a fourth connecting plate 1102 and a fifth connecting plate 1105 arranged in parallel; a sixth connecting plate 1104 for connecting the fourth connecting plate 1102 and the fifth connecting plate 1105 is provided at one end of the fourth connecting plate 1102 and the fifth connecting plate 1105; a second inclined plate 1103 is provided at the other end of the fourth connecting plate 1102 and the fifth connecting plate 1105; a third strip hole 250 is provided at the fourth connecting plate 1102 along the length direction of the fourth connecting plate 1102, and a fourth strip hole 230 is provided at the second inclined plate 1103 along the length direction of the second inclined plate 1103; the third strip hole 250 and the fourth strip hole 230 allow the threaded steel bar 1201 to pass through.

[0052] In this embodiment, when the construction personnel adjust the movement of the upper wedge 110 and the lower wedge 130, the threaded steel bar 1201 slides along the first strip hole 430, the second strip hole 220, the third strip hole 250 and the fourth strip hole 230. The first strip hole 430, the second strip hole 220, the third strip hole 250 and the fourth strip hole 230 limit the threaded steel bar 1201, thereby ensuring the stability of the upper wedge 110 and the lower wedge 130 when sliding.

[0053] In this embodiment, baffles 540 perpendicular to the third connecting plate 470 are provided on both sides of the third connecting plate 470; a plurality of threaded holes 520 are provided on the side wall of the baffle 540 at intervals along the length direction of the baffle 540; the plurality of threaded holes 520 are gradually raised along the length direction of the baffle 540; a first bolt 420 and a second bolt 450 passing through the threaded hole 520 are provided at the threaded hole 520; one end of the first bolt 420 passing through the threaded hole 520 extends forward to form a support block 1001; one end of the support plate 320 is hinged to the second connecting plate 490; two inclined plates 340 are provided on the end face of the support plate 320 near the baffle 540, and the inclined plates 340 press on the support block 1001.

[0054] In this embodiment, since the threaded hole 520 gradually rises along the length of the baffle 540, the tilt angle of the support block 1001 supporting the support plate 320 is different when the first bolt 420 is inserted into the threaded hole 520 at different positions; thus, it is convenient for construction personnel to insert the first bolt 420 into the corresponding threaded hole 520, so that the tilt angle of the support block 1001 supporting the support plate 320 corresponds to the tilt angle of the cap beam.

[0055] In this embodiment, the end of the inclined plate 340 that is hinged away from the support plate 320 is provided with a seventh connecting plate 610 for connecting the two inclined plates 340; the two baffles 540, the first connecting plate 440, the second connecting plate 490 and the third connecting plate 470 together constitute an installation groove 530 for storing fine sand; the support plate 320 is provided with an opening 510 that communicates with the installation groove 530, and a cover plate 410 for sealing the opening 510 is hinged to the opening 510.

[0056] In this embodiment, after adjusting the support angle of the support plate 320, the construction personnel open the cover plate 410 to open the sealing opening 510, and then pour fine sand into the opening 510. The fine sand enters the installation groove 530 through the opening and fills the installation groove 530, thereby supporting the support plate 320 and thus improving the support strength of the support plate 320. Before pouring in the fine sand, the construction personnel need to seal the remaining threaded holes 520 with the second bolt 450.

[0057] The seventh connecting plate 610 has an arc-shaped cross-section. After the support plate 320 rotates along the hinge end, the seventh connecting plate 610 and the inclined plate 340 will seal the gap between the mounting groove 530 and the support plate 320 to prevent fine sand from leaking out of the gap after it is injected.

[0058] In this embodiment, a push plate assembly is provided in the mounting groove 530 to compact the fine sand in the mounting groove 530. The push plate assembly includes a first push plate 306 disposed near one end of the support plate 320 and disposed along the width direction of the mounting groove 530. A first groove 390 disposed along the length direction of the first push plate 306 is provided at the first push plate 306. A second push plate 350 extending out of the first groove 390 is provided in the first groove 390. A second groove 380 disposed along the length direction of the second push plate 350 is provided inside the second push plate 350. A third push plate 330 extending out of the second groove 380 is provided in the second groove 380.

[0059] The first groove 390 is provided with a first spring 301 for pushing the second push plate 350 toward the inclined plate 340; the second groove 380 is provided with a second spring 307 for pushing the third push plate 330 toward the support plate 320; the first push plate 306 is provided with a pushing mechanism at both ends for pushing the first push plate 306 to move along the length direction of the mounting groove 530.

[0060] In this embodiment, the first spring 301 and the second spring 307 push the third push plate 330 and the second push plate 350 towards the inclined plate 340 and the support plate 320, respectively, so that the upper ends of the third push plate 330 and the second push plate 350 contact the inclined plate 340 and the support plate 320, respectively. This ensures that when the support plate 320 rotates along the hinge, the third push plate 330 and the second push plate 350 remain against the inclined plate 340 and the support plate 320. After the tilt angle of the support plate 320 is adjusted and fine sand is poured into the mounting groove 530, the construction personnel rotate the third bolt 480. At this time, the third... Bolt 480 extends into mounting groove 530, and drives connecting column 930 and flange 910 to rotate in third limiting groove 920 on push block 310, and pushes push block 310 to squeeze mounting block 302. When push block 310 slides along first inclined surface 810, it squeezes mounting block 302, thereby pushing first push plate 306, third push plate 330 and second push plate 350 to squeeze fine sand in mounting groove 530, thereby compacting the fine sand, so that the fine sand in mounting groove 530 is in a compacted state and presses against support plate 320, thereby better improving the support strength of support plate 320.

[0061] The third push plate 330 and the second push plate 350 are arc-shaped at the ends that contact the inclined plate 340 and the support plate 320, which can ensure that the fine sand is prevented from leaking out from the contact point when the third push plate 330 and the second push plate 350 move to squeeze the fine sand.

[0062] In this embodiment, the pushing mechanism includes mounting blocks 302 disposed on the sidewalls at both ends of the first push plate 306, and the mounting blocks 302 are provided with a first inclined surface 810; a third bolt 480 passing through the baffle 540 is provided on the side of the baffle 540 away from the mounting groove 530, and a push block 310 cooperating with the first inclined surface 810 is provided at one end of the third bolt 480 passing through the baffle 540; the third bolt 480 and the push block 310 are rotatably connected.

[0063] In this embodiment, the construction worker rotates the third bolt 480, which extends into the mounting groove 530 and drives the connecting column 930 and flange 910 to rotate in the third limiting groove 920 on the push block 310. This pushes the push block 310 to press against the mounting block 302. As the push block 310 slides along the first inclined surface 810, it presses against the mounting block 302, thereby pushing the first push plate 306, the third push plate 330, and the second push plate 350 to press against the fine sand in the mounting groove 530. This compresses the fine sand, keeping it in a compressed state and pressing it against the support plate 320, thus improving the support strength of the support plate 320.

[0064] In this embodiment, a guide post 304 extending toward the first push plate 306 is provided at the second connecting plate 490, and a sleeve 303 for the guide post 304 to extend into is provided at the first push plate 306; a tension spring 820 is provided inside the sleeve 303 to pull the guide post 304 and the first push plate 306 to move toward each other.

[0065] In this embodiment, when the first push plate 306 is pushed by the push block 310, the sleeve 303 moves along the guide post 304, thereby improving the stability of the first push plate 306 during movement. After the construction personnel remove the main body 100 of the device, they open the support plate 320 to pour out the fine sand in the mounting groove 530, and then rotate the third bolt 480 to pull the push block 310 to move. During the process of the push block 310 moving to the bottom of the first inclined surface 810, the tension spring 820 will pull the first push plate 306 to move, thereby completing the reset of the first push plate 306.

[0066] In this embodiment, a plurality of first reinforcing plates 210 are provided between the first connecting plate 440, the first inclined plate 460 and the third connecting plate 470; a plurality of second reinforcing plates 240 are provided between the fifth connecting plate 1105, the sixth connecting plate 1104 and the fourth connecting plate 1102.

[0067] Through this embodiment, the first reinforcing plate 210 and the second reinforcing plate 240 better improve the overall structural strength of the upper wedge block 110 and the lower wedge block 130.

[0068] In this embodiment, the first connecting plate 440, the first inclined plate 460, the third connecting plate 470 and the first reinforcing plate 210 together constitute the first limiting groove 150; the fifth connecting plate 1105, the sixth connecting plate 1104, the fourth connecting plate 1102 and the second reinforcing plate 240 together constitute the second limiting groove 140.
