Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a template adjusting device for building construction. Background Art

[0002] Building construction refers to the process of converting the plans on design drawings into actual buildings through a series of technical activities during the implementation phase of engineering construction. This process includes multiple links from preliminary preparation to final acceptance, involving civil engineering, decoration engineering, mechanical and electrical installation engineering and other aspects.

[0003] Formwork is often used in the construction process. Formwork is a temporary support structure used in concrete construction. Its main function is to ensure that concrete structures and components are correctly formed according to the geometric shape and position required by the design, and to bear the self-weight of the formwork and external loads applied during the construction process.

[0004] In the process of building the formwork, sometimes due to the height difference of the concrete pouring plane and other reasons, it is necessary to calibrate the height of the formwork so that the position of the formwork meets the design requirements; when calibrating the height of the formwork, a height calibration device is required. In the related technology, for example, Chinese patent CN212802571U discloses a formwork height calibration device. When the formwork height calibration device is in use, the bottom plate of the bracket is used to support the bottom surface of the formwork, and then the formwork and the side plate of the bracket are fixed by screws, so that the bracket is stably installed below the formwork, and an internal threaded sleeve is fixedly installed on the outer side of the bracket, and a pitch adjusting screw is inserted into the internal thread of the internal threaded sleeve. Then, by rotating the pitch adjusting screw, the bottom end of the pitch adjusting screw can be supported on the ground, and then the bracket and the formwork are lifted upward, thereby achieving the purpose of calibrating the height of the formwork.

[0005] However, there are also some problems in the process of adjusting the height of the template by the above-mentioned template height adjustment device: due to the uncertainty of the height of the template that needs to be adjusted, the friction and wear degree of the mating thread surfaces between the pitch adjusting screw and the internal threaded sleeve under different height adjustment conditions are quite different, which will lead to uneven wear of the pitch adjusting screw. This uneven wear will significantly reduce the structural strength of the pitch adjusting screw in the severely worn parts, thereby affecting the stability and reliability of the entire height adjustment device during use. Summary of the invention

[0006] Based on this, it is necessary to provide a template adjustment device for construction to address the problems of poor reliability and low stability of the current template height adjustment device during use.

When the two pitch-adjusting screws are in the second position, the locking rod is pulled out of the meshing position of the two first gears to unlock the two pitch-adjusting screws; the locking positioning portion is inserted in the mounting shell and can elastically slide along the extending direction perpendicular to the pitch-adjusting screws.

[0026] like Figures 1 to 11 As shown, the template adjustment device for construction provided by the embodiment of the present invention is used to adjust the height of the template 16, and is configured to include a bracket 1, a sliding seat 2 and a pitch adjustment screw 3. The bracket 1 is assembled on the template 16 when in use, and is detachably connected to the template 16; the sliding seat 2 is arranged on the bracket 1 and can slide in the vertical direction; the sliding seat 2 can slide in a direction perpendicular to the board surface of the template 16 to form a one-way fit with the bracket 1 or to disengage the one-way fit, and when the sliding seat 2 and the bracket 1 form a one-way fit, the sliding seat 2 can move downward in the vertical direction relative to the bracket 1; the pitch adjustment screw 3 extends in the vertical direction, and is threadedly inserted into the sliding seat 2, and is configured to be able to adjust the height of the bracket 1 from the ground.

[0027] Specifically in this embodiment, Figure 1 As shown, the bracket 1 can be set as a strip-shaped plate structure. The bracket 1 extends in the vertical direction during installation and is set on the left plate surface of the template 16 and is set close to the bottom of the template 16. In order to enable the bracket 1 to form a detachable connection with the template 16, the template adjustment device for construction is set to also include at least two first bolts, a mounting groove and a first nut. The first bolt is set vertically through the plate surface of the bracket 1; the mounting groove is vertically opened on the left plate surface of the template 16 and is set corresponding to the first bolt; the first nut is fixedly inserted in the mounting groove, and the axis of the first nut is set perpendicular to the plate surface of the template 16, and the first nut can form a threaded fit with the first bolt. In this way, when the bracket 1 is assembled on the template 16, the bracket 1 can be fixed on the template 16 by screwing into the mounting groove through the threaded fit between the first bolt and the first nut.

[0028] For example, taking the example that the number of first bolts, mounting grooves and first nuts are all four, the four first bolts are respectively arranged at the four corners of the bracket 1, and vertically penetrate the plate surface of the bracket 1; the four mounting grooves are vertically opened on the left plate surface of the template 16, and are arranged corresponding to the first bolts; the four first nuts are respectively fixedly inserted in the four mounting grooves.

[0029] In order to enable the sliding seat 2 to slide in the vertical direction and in the direction perpendicular to the board surface of the template 16, the template adjustment device for construction can be configured to also include two slide grooves 10, two slide bars 11, four plug rods 12 and four first compression springs 13. The slide groove 10 is opened on the bracket 1 and extends in the vertical direction. The two slide grooves 10 are symmetrically arranged; the two slide bars 11 are slidably inserted in the two slide grooves 10 respectively; the four plug rods 12 are divided into two groups, and the two groups are arranged at intervals in the left and right directions. The two plug rods 12 in the same group are arranged at intervals in the vertical direction, and the left ends are both suspended and the right ends are both vertical. It passes through the sliding seat 2 and is fixedly inserted on the same sliding bar 11; the four first compression springs 13 are respectively sleeved on the four insertion rods 12 during installation. In order to prevent the first compression springs 13 from detaching from the insertion rod 12, a boss is provided at the left end of each insertion rod 12. When installed, the left end of the first compression spring 13 abuts against the convex strip, and the right end abuts against the sliding seat 2. Under the action of the first compression spring 13, the sliding seat 2 has a tendency to move to the right, so that it can be pressed against the bracket 1. At the same time, the sliding seat 2 can be set away from the bracket 1 under the action of external force (hand pulling method) so as to be able to change the position of the sliding seat 2 on the bracket 1 along the vertical direction.

[0030] In order to more clearly describe the positional relationship between the slide bar 11, the insert rod 12, the boss, and the first compression spring 13, as shown in FIG. Figure 5 As shown, Figure 5 The left side corresponds to the right side, Figure 5 The right side corresponds to the left side. When installed, the left end of the plug rod 12 vertically passes through the sliding seat 2 and is fixedly inserted in the slide bar 11. The right end is suspended. The boss is set at the right end of the plug rod 12. When installed, the left end of the first compression spring 13 abuts on the sliding seat 2, and the right end abuts on the boss.

[0031] Initially, the sliding seat 2 and the bracket 1 form a one-way fit.

[0032] During use, first rotate the first bolt so that the first bolt is gradually screwed into the installation groove through the thread cooperation with the first nut. Driven by the first bolt, the bracket 1 moves toward the direction close to the template 16 to be fixed on the template 16. At this time, the bottom end of the adjustable screw 3 is supported on the ground, and the threads on the bottom outer peripheral wall of the adjustable screw 3 are all cooperated with the sliding seat 2. The sliding seat 2 is located at the lower end of the slide groove 10; then, according to the height of the bracket 1 that needs to be adjusted from the ground, the adjustable screw 3 is rotated by a preset number of circles, so that the adjustable screw 3 moves downward relative to the sliding seat 2 to lift the bracket 1 and the template 16.

[0033] After the height adjustment is completed, the bracket 1 is removed from the old template 16, and then compared with the new template 16, the sliding seat 2 is driven to move away from the bracket 1, so that the sliding seat 2 and the bracket 1 are out of one-way fit, and then the sliding seat 2 is driven to move upward until the bracket 1 is installed on the new template 16, the bottom end of the pitch adjusting screw 3 can touch the ground, and then the sliding seat 2 is driven to move towards the bracket 1, so that the sliding seat 2 and the bracket 1 form a one-way fit again, and then the above process of installing the bracket 1 on the new template 16 is repeated, and the next height adjustment can be started.

[0034] After adjusting the height of the bracket 1 from the ground for multiple times, the sliding seat 2 reaches the upper top of the slide groove 10 or the top of the pitch-adjusting screw 3 and moves downward to the limit position, and then drives the sliding seat 2 to move away from the bracket 1, so that the sliding seat 2 and the bracket 1 are disengaged from the one-way cooperation, and then drives the sliding seat 2 to move downward to the lower end of the slide groove 10, and then drives the pitch-adjusting screw 3 to rotate to the bottom and move upward to the limit position, and then a new round of height adjustment of the template 16 can be started.

[0035] In the above-mentioned height adjustment process, because the position of the sliding seat 2 is adjusted last time based on the position of the sliding seat 2 last time, the threaded mating surfaces of the adjusting screw 3 and the sliding seat 2 used for each height adjustment are different. This adjustment method makes the frequency and degree of use of the threads of each part of the adjusting screw 3 tend to be consistent, effectively avoiding the problem of local excessive wear, greatly improving the utilization rate of the adjusting screw 3, and thereby enhancing the stability and reliability of the entire template 16 adjustment device during use.

[0036] In other embodiments, in order to enable the sliding seat 2 to slide in the vertical direction and in the direction perpendicular to the board surface of the template 16, the template adjustment device for construction, in addition to being configured to include two slide grooves 10 and two slide bars 11, can also be configured to include four second bolts and four second nuts, wherein the second bolts are used to replace the insert rods 12, the second nuts are used to replace the bosses and the first compression springs 13, and the heads of the second bolts are fixedly set on the slide bars 11, and the second nuts are threadedly sleeved on the second bolts. In this way, when the position of the sliding seat 2 on the bracket 1 does not need to be changed, the sliding seat 2 can be fixed on the bracket 1 by tightening the second nuts; when the position of the sliding seat 2 on the bracket 1 needs to be changed, the second nuts can be loosened to facilitate changing the position of the sliding seat 2 on the bracket 1 in the vertical direction.

[0037] In some embodiments, there are two pitch-adjusting screws 3, which are arranged side by side; the template adjustment device for construction is also arranged to include two first gears 4, which are respectively fixedly sleeved on the two pitch-adjusting screws 3 and mesh with each other. In this way, it is possible to avoid the problem that when adjusting with a single adjusting screw, the torque generated by the rotation of the pitch-adjusting screw 3 may cause the sliding seat 2 to shake, deviate, or be unstable on the bracket 1, thereby affecting the accuracy of the template 16 height adjustment and the reliability of the device.

[0038] Specifically in this embodiment, Figure 1 As shown, the two pitch-adjusting screw rods 3 are arranged side by side in the front-to-back direction; to ensure the stability during support, the upper and lower ends of the two pitch-adjusting screw rods 3 are respectively arranged flush; Figure 6 and Figure 7 As shown, the first gear 4 is arranged near the lower end of the pitch adjusting screw 3. In this way, it can avoid that when it is arranged in the upper middle, middle, and lower middle parts of the pitch adjusting screw 3, the thread is cut into two parts in the vertical direction, which leads to the thread located at the lower part of the first gear 4 being unusable and causing waste. On the other hand, it will shorten the adjustment stroke of the pitch adjusting screw 3 and affect the scope of application.

[0039] More specifically, in order to ensure that the two pitch-adjusting screws 3 can move in the same direction when rotating in opposite directions, the thread grooves on the sliding seat 2 that are respectively threadably matched with the two pitch-adjusting screws 3 are arranged to have opposite rotation directions.

[0040] When adjusting the height of the template 16, the pitch-adjusting screw 3 is rotated a preset number of times according to the height from the ground that the bracket 1 needs to be adjusted. Due to the meshing transmission relationship between the two first gears 4, when one of the pitch-adjusting screws 3 is rotated, the other pitch-adjusting screw 3 is driven to rotate through the first gear 4 meshing therewith, so that the two pitch-adjusting screws 3 turn in opposite directions, thereby enabling the two pitch-adjusting screws 3 to move downward relative to the sliding seat 2 at the same time to lift the bracket 1 and the template 16.

[0041] During the rotation of the pitch adjusting screw 3, since the two pitch adjusting screws 3 have opposite directions of rotation, the directions of the torques generated on the sliding seat 2 when they rotate are also opposite, thereby achieving mutual offset of the torques. Through this torque offset method, the stability and reliability of the sliding seat 2 on the bracket 1 can be significantly improved.

[0042] In other embodiments, the existing height adjustment device is generally used manually or electrically (electric lever plus sleeve) when adjusting the height of the template 16, which cannot accurately control the height adjustment amount, and there is often an over-adjustment situation, which requires repeated adjustment, thereby further aggravating the local wear of the pitch adjustment screw 3. At the same time, the locking method after adjustment is relatively simple, and the adjustment screw will be subjected to a friction force perpendicular to the axis, which will damage the thread on the surface of the adjustment screw in the long run, thereby aggravating the problem of uneven wear. In severe cases, it will also cause the adjustment screw to bend and become scrapped. In order to solve the above problems, the template adjustment device for construction is set to also include an adjustment mechanism, and the adjustment mechanism is configured to be able to adjust the number of rotations of the pitch adjustment screw 3 according to the height from the ground that the bracket 1 needs to be adjusted. In this way, when in use, under the action of the adjustment mechanism, the number of rotations of the pitch adjustment screw 3 can be adjusted according to the height from the ground that the bracket 1 needs to be adjusted, thereby reducing the error caused by manual adjustment and facilitating the improvement of the adjustment accuracy.

[0043] Furthermore, the adjustment mechanism is configured to include a mounting shell 501, a scale line 502, an adjustment portion 503, a rack 504, a rotating shaft 505, a second gear 506, a locking rod 507, a locking positioning portion 508, a mounting seat 509, a knob 5010, a third gear 5011 and a cutting assembly 5012.

The locking rod 507 is inserted into the meshing position of the two first gears 4 to lock the two pitch-adjusting screws 3. When in the second position, the locking rod 507 is pulled out of the meshing position of the two first gears 4 to unlock the two pitch-adjusting screws 3. The locking positioning portion 508 is inserted into the mounting shell 501 and can elastically slide along the extending direction perpendicular to the pitch-adjusting screw 3. The locking positioning portion 508 is configured to lock the locking rod 507 in the second position, and when the adjusting portion 503 is located at the zero scale on the scale line 502, the locking rod 507 is locked. The stop positioning portion 508 and the rack 504 form a stopper match, and can unlock the locking of the locking positioning portion 508 to the locking rod 507; the knob 5010 is arranged on the mounting shell 501 and can rotate around its own axis; the mounting seat 509 is inserted in the mounting shell 501, and is sleeved on the knob 5010, and can slide relative to the knob 5010 along the extension direction of the pitch adjusting screw 3; the third gear 5011 is sleeved on the mounting seat 509, and can rotate synchronously with the knob 5010, and can slide synchronously with the mounting seat 509 along the extension direction of the pitch adjusting screw 3.

[0046] To facilitate the installation of the adjustment part 503, a mounting hole is opened on the left side wall of the mounting shell 501, and the mounting hole extends in the front-to-back direction. The mounting hole is located below the scale line 502 to indicate the adjustment distance of the adjustment part 503; the adjustment part 503 is set as a C-shaped structure, and has a base strip and base rods located at both ends of the base strip. The base rod and the base strip are vertically arranged. The base strip extends in the front-to-back direction when installed, and is located outside the mounting shell 501, and can form a stopper with the mounting shell 501 to avoid the base rod from being inserted into the mounting hole, resulting in the inability to realize the adjustment function of the adjustment part 503. The base rod passes through the mounting hole when installed. With the cooperation of the two base rods and the mounting hole, the adjustment part 503 can Slide along the front-to-back direction; the rack 504 extends along the front-to-back direction and is vertically connected to the ends of the two base rods away from one end of the base strip; in order to facilitate the elastic sliding of the adjustment part 503 along the board surface direction perpendicular to the template 16, the template adjustment device for construction is configured to also include two gaskets 14 and two second compression springs 15, the two gaskets 14 are respectively sleeved on the two base rods, and are inserted into the mounting shell 501, and can form a stop fit with the inner side wall of the mounting shell 501, the two second compression springs 15 are respectively sleeved on the two base rods, and the two ends are respectively abutted between the gaskets 14 and the rack 504, and under the action of the second compression springs 15, the adjustment part 503 has a tendency to be inserted into the mounting shell 501.

[0047] Optionally, the gasket 14 can be configured as a round gasket.

[0048] Optionally, a bearing may be provided at the lower end of each pitch-adjusting screw 3 and above the first gear 4 , and the bearing is inserted into the mounting shell 501 at the same time to improve the smoothness of the pitch-adjusting screw 3 when rotating.

[0049] Optionally, to facilitate the movement of the adjustment portion 503, a handle is provided in the middle of the left side wall of the base strip.

[0050] The rotating shaft 505 is vertically placed in the mounting shell 501 and is coaxially fixedly arranged with the pitch adjusting screw 3 located at the rear side; the second gear 506 is fixedly sleeved on the lower end of the rotating shaft 505 and meshes with the rack 504; Fig.11 As shown, in order to facilitate the elastic sliding of the locking rod 507 along the extension direction of the pitch adjusting screw 3, the adjustment mechanism is configured to further include a third compression spring 5013, which is vertically arranged in the mounting shell 501 and connected between the lower end of the locking rod 507 and the mounting shell 501. Under the action of the third compression spring 5013, the locking rod 507 has a tendency to move upward. Fig.10The locking rod 507 is in the second position, at which time the locking rod 507 is pulled out of the meshing position of the two first gears 4; to facilitate the engagement between the locking positioning portion 508 and the locking rod 507, a slot 5071 is provided at the lower position of the locking rod 507, and a clamping block 5081 is provided on the locking positioning portion 508, and the clamping block 5081 can be engaged with the slot 5071; to facilitate the locking positioning portion 508 to elastically slide along the extension direction perpendicular to the pitch adjusting screw 3, the adjustment mechanism is configured to also include a fourth compression spring 5014, which is horizontally inserted in the mounting shell 501 and extends in the front-rear direction and is connected between the locking positioning portion 508 and the mounting shell 501. Under the action of the fourth compression spring 5014, the locking positioning portion 508 has a tendency to move backward, so that the clamping block 5081 has a tendency to be clamped into the slot 5071.

[0051] To more clearly describe the positional relationship among the third compression spring 5013, the block 5081 and the slot 5071, as shown in FIG. Fig.11 As shown, Fig.11 The left side is the rear, Fig.11 The right side in the figure is the front, the third compression spring 5013 extends horizontally in the left-right direction and is sleeved on the locking positioning portion 508; the slot 5071 is opened on the right side wall of the locking rod 507; and the block 5081 is arranged on the left side wall of the locking positioning portion 508.

[0052] The knob 5010 is vertically arranged and passes through the top of the mounting shell 501 and is located in front of the pitch-adjusting screw 3 on the front side; the mounting seat 509 is arranged as a cylindrical structure and is vertically inserted into the mounting shell 501, and the top of the mounting seat 509 is open to facilitate the installation of the third gear 5011; in order to enable the third gear 5011 to rotate synchronously with the knob 5010 and slide synchronously with the mounting seat 509 along the extension direction of the pitch-adjusting screw 3, the bottom of the third gear 5011 is provided with a plurality of protruding teeth, each of which is provided with a plurality of protruding teeth. A ring stage 50111 is coaxially arranged, and the ring stage 50111 is rotatably inserted in the mounting seat 509. Under the action of the ring stage 50111, the third gear 5011 can not only move synchronously with the mounting seat 509 in the vertical direction, but also rotate relative to the mounting seat 509. A spline fit is formed between the third gear 5011 and the knob 5010. Under the spline fit, the third gear 5011 can not only rotate synchronously with the knob 5010, but also move vertically relative to the knob 5010.

[0053] To more clearly describe the positional relationship between the knob 5010, the third gear 5011 and the mounting base 509, as shown in FIG. Fig.10 As shown, Fig.10 The left side is the rear, Fig.10 The right side in the figure is the front, and at this time the third gear 5011 is in the fourth position and is meshed with the first gear 4 on the pitch adjusting screw 3 located on the right side.

[0054] Initially, the locking rod 507 is in the first position and inserted into the meshing position of the two first gears 4 to lock the two pitch-adjusting screws 3; the third gear 5011 is in the third position, and the third gear 5011 and the first gear 4 on the pitch-adjusting screw 3 located on the front side are disengaged.

[0055] During the height adjustment process, after the bracket 1 is installed on the template 16, the adjusting part 503 is first driven to move to the left, and while compressing the second compression spring 15, the rack 504 and the second gear 506 are disengaged, and then the adjusting part 503 is driven to move backward, so that the adjusting part 503 moves to the scale on the scale line 502 corresponding to the height from the ground that the bracket 1 needs to be adjusted, and then the adjusting part 503 is released, and the adjusting part 503 moves to the right under the action of the second compression spring 15, so that the rack 504 is meshed with the gear again.

[0056] Then, the switching assembly is used to move the locking rod 507 from the first position to the second position and the third gear 5011 from the third position to the fourth position. When the locking rod 507 is in the second position, the locking rod 507 pulls out the meshing point of the two first gears 4 to unlock the two adjustable pitch screws 3. The third compression spring 5013 is in a compressed state. At the same time, the locking positioning portion 508 locks the locking rod 507 in the second position through the engagement between the block 5081 and the slot 5071 to limit the rebound of the third compression spring 5013. When the third gear 5011 is in the fourth position, the third gear 5011 is engaged with the first gear 4 on the adjustable pitch screw 3 located on the front side.

[0057] Then, the knob 5010 is turned, and the knob 5010 drives the third gear 5011 to rotate. The third gear 5011 drives the pitch-adjusting screw 3 on the front side to rotate by meshing with the first gear 4 on the pitch-adjusting screw 3 on the front side. At the same time, the pitch-adjusting screw 3 on the front side drives the pitch-adjusting screw 3 on the rear side to rotate by meshing between the first gear 4 thereon and the first gear 4 on the pitch-adjusting screw 3 on the rear side, so that both pitch-adjusting screws 3 move downward relative to the sliding seat 2 to lift the bracket 1 and the template 16. On the other hand, the second gear 506 is driven to rotate through the rotating shaft 505, and the second gear 506 drives the adjusting part 503 to move forward by meshing with the rack 504.

[0058] When the adjustment part 503 moves to the point where the rack 504 and the locking positioning part 508 form a stop fit, as the knob 5010 continues to rotate, the adjustment part 503 continues to move and drives the locking positioning part 508 to move forward, while compressing the fourth compression spring 5014, the block 5081 and the slot 5071 are disengaged, and under the action of the third compression spring 5013, the locking rod 507 moves from the second position to the first position and is reinserted into the meshing position of the two first gears 4 to lock the two adjusting screws 3. At the same time, under the action of the switching assembly, the third gear 5011 moves from the fourth position to the third position to disengage from the first gear 4 on the adjusting screw 3 on the front side, thereby achieving automatic locking, avoiding over-adjustment or under-adjustment, and ensuring adjustment accuracy.

[0059] Furthermore, the cutting assembly 5012 is configured to include a shift rod 50121 and a lever 50122, the shift rod 50121 is inserted into the mounting shell 501, and extends in a direction perpendicular to the board surface of the template 16, and can rotate around its own axis; the lever 50122 and the shift rod 50121 are vertically arranged, and the middle part is fixedly sleeved on the shift rod 50121; the locking rod 507 and the mounting seat 509 are respectively hinged at both ends of the lever 50122.

[0060] Specifically, Figure 7 As shown, the lever 50121 extends in the left-right direction, with the left end located outside the mounting shell 501, and the right end rotatably inserted into the mounting shell 501; the lever 50122 extends in the front-back direction, and the middle part is fixedly sleeved on the right end of the lever 50121, the middle part of the locking rod 507 is hinged to the rear end of the lever 50122, and the lower end of the mounting seat 509 is hinged to the front end of the lever 50122.

[0061] Initially, the rear end of the lever 50122 is high and the front end is low. At this time, the locking rod 507 is in the first position and inserted into the meshing position of the two first gears 4 to lock the two adjustable screws 3; the third gear 5011 is in the third position, and the third gear 5011 and the first gear 4 on the adjustable screw 3 located on the front side are disengaged.

[0062] After the rack 504 is meshed with the second gear 506 again, the lever 50121 is rotated so that the rear end of the lever 50122 is low and the front end is high. Figure 7 As shown, at this time, the locking rod 507 is in the second position and disengages from the meshing position of the two first gears 4 to unlock the two pitch-adjusting screws 3. The third compression spring 5013 is in a compressed state. At the same time, the locking positioning portion 508 locks the locking rod 507 in the second position through the engagement between the block 5081 and the slot 5071 to limit the rebound of the third compression spring 5013; the third gear 5011 is in the fourth position, and the third gear 5011 is engaged with the first gear 4 on the pitch-adjusting screw 3 located on the front side.

[0063] As the adjustment portion 503 moves, when the block 5081 and the slot 5071 are disengaged, the locking rod 507 moves from the second position to the first position under the action of the third compression spring 5013, and the locking rod 507 simultaneously drives the third gear 5011 to move downward through the lever 50122 to move from the fourth position to the third position. At this time, the rear end of the lever 50122 is high and the front end is low.

[0064] In a further embodiment, in order to improve the convenience of rotating the lever 50121 , the template adjustment device for construction also includes a pushing part 6 , which is arranged on the lever 50121 and located outside the mounting shell 501 .

[0065] Specifically in this embodiment, Figure 3 and Figure 7 As shown, the push portion 6 is configured as a strip structure and is vertically disposed at the left end of the lever 50121. The push portion 6 and the lever 50121 together form an L-shaped structure. In this way, when the lever 50121 needs to be rotated, the lever 50121 can be driven to rotate by manually moving the push portion 6.

[0066] In other embodiments, when the existing height adjustment device adjusts the height of the template 16, the adjusting screw will gradually tilt under the support of the ground, resulting in the inability of the adjusting screw to form a stable support with the ground, and because the adjusting screw is approximately in point contact with the ground, the adjusting screw may slip under the action of the gravity of the template 16, thereby affecting the accuracy of subsequent height adjustment of the template 16 and affecting the stable support of the template 16. In order to solve the above problems, the template adjustment device for construction also includes a support seat 7, which is hinged to the bottom of the mounting shell 501 and is supported on the ground when in use.

[0067] Specifically in this embodiment, Figure 4 As shown, the support seat 7 is configured as a flat plate structure, and the top of the support seat 7 is hinged to the bottom of the mounting shell 501. In this way, when the pitch adjusting screw 3 extends downward relative to the sliding seat 2, the support seat 7 can maintain surface contact with the ground due to the hinged setting, thereby ensuring the support stability of the template 16.

[0068] In other embodiments, the bracket 1 is detachably connected to the template 16 by screws.

[0069] Specifically in this embodiment, the number of screws can be four, and they are respectively set at the four corners of the bracket 1. In this way, the bracket 1 can be fixed on the template 16 by tightening the screws.

[0070] In other embodiments, in order to achieve one-way cooperation between the bracket 1 and the sliding seat 2, the template adjustment device for construction also includes a first ratchet 8 and a second ratchet 9. The first ratchet 8 is arranged on the bracket 1 and extends along the extension direction of the distance adjusting screw 3; the second ratchet 9 is arranged on the sliding seat 2 and extends along the extension direction of the distance adjusting screw 3, and can form a one-way cooperation with the first ratchet 8.

[0071] Specifically in this embodiment, Figure 5 As shown, Figure 5 The left side corresponds to the right side, Figure 5 The right side in the figure corresponds to the left side, the first ratchet 8 is arranged on the right plate surface of the bracket 1, and the inclined surface of the first ratchet 8 extends in the lower right direction, and the second ratchet 9 is arranged on the left side wall of the sliding seat 2, and the inclined surface of the second ratchet 9 extends in the upper left direction. In this way, under the cooperation of the first ratchet 8 and the second ratchet 9, the sliding seat 2 can move downward in the vertical direction relative to the bracket 1.

[0072] In other embodiments, in order to improve the supporting effect of the template 16 and reduce the wear of the screws or the first bolts and the first nuts, the bracket 1 is configured to include vertically arranged side panels and a bottom plate, and the side panels are arranged to overlap with the surface of the template 16 when in use, and the bottom plate is supported on the bottom of the template 16.

[0073] Specifically in this embodiment, the bracket 1 is set as an L-shaped structure. In this way, the setting of the bottom plate can share part of the gravity of the template 16, so that the load originally concentrated on the connecting parts (screws or first bolts and first nuts) is effectively dispersed, which can not only improve the overall support effect of the template 16 and ensure the stability and reliability of the template 16 during the construction process, but also significantly reduce the wear of the connecting parts such as screws or first bolts and first nuts, extend their service life, and reduce construction costs.

[0074] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
