Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly to a formwork adjusting device for building construction. Background Art

[0002] Building construction refers to the process of transforming the plan on the design drawings into an actual building through a series of technical activities during the implementation stage of project construction. This process includes multiple links from pre-construction preparation to completion acceptance, involving multiple aspects such as civil engineering, decoration engineering, and mechanical and electrical installation engineering.

[0003] During the building construction process, formwork is commonly used. Formwork is a temporary support structure for concrete construction, and its main function is to ensure that the concrete structure 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 the external loads applied during the construction process.

[0004] During the process of erecting the formwork, sometimes due to reasons such as height differences in the concrete pouring plane, it is necessary to calibrate the height of the formwork to make the position of the formwork meet the design requirements; when calibrating the height of the formwork, a height calibration device is required. In the related art, for example, Chinese Patent CN212802571U discloses a formwork height calibration device. When this 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 is fixed to the side plate of the bracket through screws, so as to stably install the bracket below the formwork. An internally threaded sleeve is fixedly installed on the outside of the bracket, and an adjustable distance screw is threadedly inserted into the internally threaded sleeve. Then, by rotating the adjustable distance screw, the bottom end of the adjustable distance screw can be jacked against the ground, and then the bracket and the formwork can be jacked upward to achieve the purpose of calibrating the height of the formwork.

[0005] However, the above-mentioned formwork height calibration device also has some problems during the process of calibrating the height of the formwork: due to the uncertainty of the height that the formwork needs to be adjusted, there are significant differences in the frictional force and wear degree borne by the mating thread surface between the adjustable distance screw and the internally threaded sleeve under different height calibration working conditions, which will lead to uneven wear of the adjustable distance screw. This uneven wear will significantly reduce the structural strength of the adjustable distance screw at the severely worn part, and further affect the stability and reliability of the entire height calibration device during use. Summary of the Invention

[0006] Based on this, in view of the problems of poor reliability and low stability existing in the current formwork height calibration device during use, it is necessary to provide a formwork adjusting device for building construction.

[0007] The above object is achieved by the following technical solutions:

[0008] A formwork adjusting device for building construction, the formwork adjusting device for building construction includes:

[0009] A support which is assembled on a formwork during use and forms a detachable connection with the formwork.

[0010] A sliding seat which is arranged on the support and can slide in the vertical direction; the sliding seat can slide in a direction perpendicular to the plate surface of the formwork to form a one-way fit or disengage from a one-way fit with the support, and when the sliding seat forms a one-way fit with the support, the sliding seat can move downward relative to the support in the vertical direction.

[0011] An adjustable screw which extends in the vertical direction and is threadedly inserted through the sliding seat and is configured to be able to adjust the ground clearance height of the support.

[0012] After each height adjustment is completed, the support is removed from the old formwork, compared with the new formwork, the sliding seat and the support are adjusted to disengage from the one-way fit, and then the sliding seat is driven to move upward until when the support is installed on the new formwork, the bottom end of the adjustable screw can contact the ground, and then the sliding seat and the support are adjusted to form a one-way fit; after adjusting the ground clearance height of the support multiple times, when the sliding seat reaches the uppermost limit position on the support or the top end of the adjustable screw moves downward to the limit position, the sliding seat is driven to move downward in the vertical direction to the lowermost limit position on the support, and the adjustable screw is driven to rotate until the bottom end moves upward to the limit position.

[0013] Further, there are two adjustable screws, and the two adjustable screws are arranged side by side; the formwork adjusting device for building construction further includes two first gears which are respectively fixedly sleeved on the two adjustable screws and mesh with each other.

[0014] Further, the formwork adjusting device for building construction further includes an adjusting mechanism which is configured to be able to adjust the number of rotation turns of the adjustable screw according to the ground clearance height that the support needs to be adjusted.

[0015] Further, the adjusting mechanism includes a mounting shell, scale lines, a position adjusting part, a rack, a rotating shaft, a second gear, a locking rod, a locking and positioning part, a mounting seat, a knob, a third gear, and a cutting component. The mounting shell is commonly sleeved on the bottom ends of the two distance adjusting screws and is rotatably connected to the distance adjusting screws. The scale lines are arranged on the mounting shell and are arranged along a direction perpendicular to the extending direction of the distance adjusting screws. The position adjusting part is inserted into the mounting shell and can slide along a direction perpendicular to the extending direction of the distance adjusting screws so as to move to the scale at the corresponding scale line of the ground height to be adjusted of the bracket, and can elastically slide along a direction perpendicular to the plate surface of the template. The rack is inserted into the mounting shell, extends along a direction perpendicular to the extending direction of the distance adjusting screws, and is fixedly arranged on the position adjusting part. The rotating shaft is vertically arranged in the mounting shell, and the top end of the rotating shaft is coaxially and fixedly arranged at the bottom end of one of the distance adjusting screws. The second gear is fixedly sleeved on the rotating shaft and can mesh with the rack. The locking rod is vertically arranged in the mounting shell, can elastically slide along the extending direction of the distance adjusting screws, and has corresponding first and second positions before and after sliding. When in the first position, the locking rod is inserted into the meshing position of the two first gears to lock the two distance adjusting screws. When in the second position, the locking rod is pulled out from the meshing position of the two first gears to unlock the two distance adjusting screws. The locking and positioning part is inserted into the mounting shell and can elastically slide along a direction perpendicular to the extending direction of the distance adjusting screws. The locking and positioning part is configured to lock the locking rod in the second position, and when the position adjusting part is at the zero scale of the scale line, the locking and positioning part forms a stop fit with the rack and can unlock the locking of the locking rod by the locking and positioning part. The knob is arranged on the mounting shell and can rotate around its own axis. The mounting seat is inserted into the mounting shell, sleeved on the knob, and can slide relative to the knob along the extending direction of the distance adjusting screws. The third gear is inserted into the mounting seat and can rotate synchronously with the knob and can also slide synchronously with the mounting seat along the extending direction of the distance adjusting screws. When the third gear slides along the extending direction of the distance adjusting screws, it has corresponding third and fourth positions. When in the third position, the third gear is disengaged from the first gear. When in the fourth position, the third gear is engaged with the first gear. The cutting component is configured to be able to switch the positions of the locking rod and the third gear simultaneously.

[0016] Further, the cutting component includes a shift lever and a lever. The shift lever is inserted into the mounting shell, extends in a direction perpendicular to the plate surface of the template, and is capable of rotating around its own axis. The lever is vertically arranged with the shift lever, and is fixedly sleeved on the shift lever in the middle. The locking rod and the mounting seat are respectively hinged to both ends of the lever.

[0017] Further, the formwork adjusting device for building construction further includes a pushing part, which is arranged on the shift lever and located outside the mounting shell.

[0018] Further, the formwork adjusting device for building construction further includes a support base, which is hinged to the bottom of the mounting shell and supports on the ground during use.

[0019] Further, the bracket is detachably connected to the template by screws.

[0020] Further, the formwork adjusting device for building construction further includes a first ratchet and a second ratchet. The first ratchet is arranged on the bracket and extends along the extending direction of the distance adjusting screw. The second ratchet is arranged on the sliding seat and extends along the extending direction of the distance adjusting screw, and can form a one-way fit with the first ratchet.

[0021] Further, the bracket includes a side plate and a bottom plate which are vertically arranged. The plate surface of the side plate coincides with the plate surface of the template during use, and the bottom plate supports at the bottom of the template.

[0022] The beneficial effects of the present invention are:

[0023] After each height adjustment of the formwork adjustment device provided by the present invention is completed, the support is removed from the old formwork, and then compared with the new formwork. The one-way cooperation between the sliding seat and the support is adjusted to be disengaged, and then the sliding seat is driven to move upward until the bottom end of the distance adjustment screw can contact the ground when the support is installed on the new formwork. Then, the one-way cooperation between the sliding seat and the support is adjusted, and the next height adjustment can be started. After adjusting the ground clearance of the support multiple times, the sliding seat reaches the uppermost limit position on the support or the top end of the distance adjustment screw moves downward to the limit position, driving the sliding seat to move downward along the vertical direction to the lowermost limit position on the support, and driving the distance adjustment screw to rotate until the bottom end moves upward to the limit position, and a new round of formwork height adjustment can be started. During the above height adjustment process, when adjusting the position of the sliding seat for the latter time, it is adjusted on the basis of the position of the sliding seat for the previous time. Therefore, the thread mating surfaces of the distance adjustment screw and the sliding seat used each time are different, so that the usage of each part of the thread of the distance adjustment screw can tend to be consistent, effectively avoiding the problem of local excessive wear of the distance adjustment screw, greatly improving the utilization rate of the distance adjustment screw, and further enhancing the stability and reliability of the entire formwork adjustment device during use.

[0024] Further, by setting that the number of the distance adjustment screws is two, and a first gear is fixedly sleeved on each distance adjustment screw, and the two first gears are meshed with each other. When in use, due to the meshing transmission relationship between the two first gears, the rotation directions of the two distance adjustment screws are opposite, and further the torques generated by the two distance adjustment screws when rotating on the sliding seat are opposite, so that the cancellation of the torques can be realized, which is beneficial to improving the stability of the sliding seat on the support.

[0025] Further, by setting an adjustment mechanism, when in use, under the action of the adjustment mechanism, the number of turns of rotation of the distance adjustment screw can be adjusted according to the ground clearance that the support needs to be adjusted, so as to reduce the error caused by manual adjustment and be beneficial to improving the adjustment accuracy.

[0026] Further, by hinging a support seat at the bottom of the installation shell, when in use, when the distance adjustment screw extends downward relative to the sliding seat, the support seat can keep in surface contact with the ground, so as to ensure the support stability of the formwork.

[0042] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0043] As Figures 1 to 11 As shown, the formwork adjusting device for building construction provided by the embodiment of the present invention is used to level the formwork 16 and is configured to include a support 1, a sliding seat 2, and an adjusting screw 3. The support 1 is assembled on the formwork 16 during use and is detachably connected to the formwork 16; the sliding seat 2 is arranged on the support 1 and can slide in the vertical direction; the sliding seat 2 can slide in a direction perpendicular to the plate surface of the formwork 16 to form a one-way fit or disengage from a one-way fit with the support 1, and when the sliding seat 2 forms a one-way fit with the support 1, the sliding seat 2 can move downward relative to the support 1 in the vertical direction; the adjusting screw 3 extends in the vertical direction and is threadedly inserted through the sliding seat 2 and is configured to be able to adjust the ground clearance height of the support 1.

[0044] Specifically in this embodiment, as Figure 1As shown, the bracket 1 can be set as a strip-shaped plate structure. When installed, the bracket 1 extends in the vertical direction, is arranged on the left plate surface of the formwork 16, and is close to the bottom of the formwork 16. To enable the bracket 1 to be detachably connected to the formwork 16, the formwork adjusting device for construction is further provided with at least two first bolts, mounting grooves, and first nuts. The first bolts penetrate vertically through the plate surface of the bracket 1. The mounting grooves are vertically opened on the left plate surface of the formwork 16 and are correspondingly arranged with the first bolts. The first nuts are fixedly inserted into the mounting grooves, and the axes of the first nuts are perpendicular to the plate surface of the formwork 16. The first nuts can form a threaded fit with the first bolts. In this way, when assembling the bracket 1 onto the formwork 16, the bracket 1 can be fixed to the formwork 16 by screwing it into the mounting groove through the threaded fit between the first bolts and the first nuts.

[0045] Exemplarily, taking the number of the first bolts, mounting grooves, and first nuts all being set to four as an example, the four first bolts are respectively arranged at the four corners of the bracket 1 and penetrate vertically through the plate surface of the bracket 1. The four mounting grooves are vertically opened on the left plate surface of the formwork 16 and are correspondingly arranged with the first bolts. The four first nuts are respectively fixedly inserted into the four mounting grooves.

[0046] To enable the sliding seat 2 to slide not only in the vertical direction but also in the direction perpendicular to the plate surface of the formwork 16, the formwork adjusting device for construction can be further provided with two sliding grooves 10, two sliding strips 11, four inserting rods 12, and four first compression springs 13. The sliding grooves 10 are opened on the bracket 1 and extend in the vertical direction. The two sliding grooves 10 are symmetrically arranged. The two sliding strips 11 are respectively slidably inserted into the two sliding grooves 10. The four inserting rods 12 are evenly divided into two groups. The two groups are arranged at intervals in the left-right direction. The two inserting rods 12 in the same group are arranged at intervals in the vertical direction, and their left ends are all suspended, and their right ends all vertically penetrate through the sliding seat 2 and are fixedly inserted into the same sliding strip 11. The four first compression springs 13 are respectively sleeved on the four inserting rods 12 during installation. To prevent the first compression springs 13 from detaching from the inserting rods 12, a convex platform is provided at the left end of each inserting 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 tightly 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 an external force (hand-pulling method) so as to be able to change the position of the sliding seat 2 on the bracket 1 in the vertical direction.

[0047] To facilitate a clearer description of the positional relationship among the sliding strip 11, the inserting rod 12, the convex platform, and the first compression spring 13, as Figure 5 shown, Figure 5 the left side in Figure 5The right side in it corresponds to the left side. When the insertion rod 12 is installed, its left end vertically penetrates through the sliding seat 2 and is fixedly inserted into the slide bar 11, while its right end is suspended. The convex platform is arranged at the right end of the insertion rod 12. When the first compression spring 13 is installed, its left end abuts against the sliding seat 2 and its right end abuts against the convex platform.

[0048] Initially, the sliding seat 2 and the bracket 1 form a one-way fit.

[0049] During the use process, first rotate the first bolt, so that the first bolt gradually screws into the installation groove through the thread fit with the first nut. Driven by the first bolt, the bracket 1 moves towards the template 16 to be fixed on the template 16. At this time, the bottom end of the distance-adjusting screw 3 supports on the ground, and all the threads on the outer peripheral wall of the bottom of the distance-adjusting screw 3 cooperate with the sliding seat 2, and the sliding seat 2 is located at the lower end of the chute 10. Then, according to the required ground clearance height of the bracket 1, rotate the distance-adjusting screw 3 by a preset number of turns, so that the distance-adjusting screw 3 moves downward relative to the sliding seat 2 to lift the bracket 1 and the template 16.

[0050] After the height adjustment is completed, remove the bracket 1 from the old template 16, then compare with the new template 16, drive 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 fit. Then drive the sliding seat 2 to move upward until when the bracket 1 is installed on the new template 16, the bottom end of the distance-adjusting screw 3 can contact the ground. Then drive the sliding seat 2 to move towards the bracket 1, so that the sliding seat 2 and the bracket 1 form a one-way fit again. Then repeat the above process of installing the bracket 1 on the new template 16 to start the next height adjustment.

[0051] After adjusting the ground clearance height of the bracket 1 multiple times, the sliding seat 2 reaches the upper top of the chute 10 or the top end of the distance-adjusting screw 3 moves downward to the limit position. Then drive 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 fit. Then drive the sliding seat 2 to move downward to the lower end of the chute 10. Then drive the distance-adjusting screw 3 to rotate until the bottom end moves upward to the limit position to start a new round of height adjustment of the template 16.

[0052] During the above height adjustment process, because the position of the sliding seat 2 in the later adjustment is based on the position of the sliding seat 2 in the previous adjustment, the thread mating surfaces of the distance-adjusting screw 3 and the sliding seat 2 used in each height adjustment are different. This adjustment method makes the usage frequency and degree of each part of the thread of the distance-adjusting screw 3 tend to be consistent, effectively avoiding the problem of local excessive wear, greatly improving the utilization rate of the distance-adjusting screw 3, and further enhancing the stability and reliability of the entire template 16 adjusting device during the use process.

[0053] In other embodiments, to enable the sliding seat 2 to slide both in the vertical direction and in the direction perpendicular to the plate surface of the template 16, in addition to being provided with two chutes 10 and two sliding bars 11, the formwork adjusting device for construction can also be provided with four second bolts and four second nuts. The second bolts are used to replace the inserting rods 12, and the second nuts are used to replace the bosses and the first compression springs 13. The heads of the second bolts are fixedly arranged on the sliding bars 11, and the second nuts are threadedly sleeved on the second bolts. In this way, when it is not necessary to change the position of the sliding seat 2 on the bracket 1, the second nuts can be tightened to fix the sliding seat 2 on the bracket 1; when it is necessary to change the position of the sliding seat 2 on the bracket 1, the second nuts can be loosened to facilitate changing the position of the sliding seat 2 on the bracket 1 in the vertical direction.

[0054] In some embodiments, the number of the distance-adjusting screws 3 is set to two, and the two distance-adjusting screws 3 are arranged side by side; the formwork adjusting device for construction is further provided with two first gears 4, and the two first gears 4 are respectively fixedly sleeved on the two distance-adjusting screws 3 and are meshed with each other. In this way, it can avoid the problem that when the existing single adjusting screw is adjusted, the torque generated by the rotation of the distance-adjusting screw 3 may cause the sliding seat 2 to shake, shift and other unstable conditions on the bracket 1, affecting the accuracy of the formwork 16 height adjustment and the reliability of the device.

[0055] Specifically in this embodiment, as Figure 1 shown, the two distance-adjusting screws 3 are arranged side by side in the front-back direction; to ensure the stability during support, the upper and lower ends of the two distance-adjusting screws 3 are respectively flush; as Figure 6 and Figure 7 shown, the first gears 4 are arranged near the lower ends of the distance-adjusting screws 3. In this way, it can avoid the situation that when they are arranged in the upper middle part, middle part or lower middle part of the distance-adjusting screws 3, the thread is split into two parts in the vertical direction, resulting in on the one hand, the thread below the first gear 4 cannot be used, causing waste, and on the other hand, shortening the adjustment stroke of the distance-adjusting screw 3 and affecting the applicable range.

[0056] More specifically, to ensure that the two distance-adjusting screws 3 can move in the same direction when rotating in opposite directions, the helix directions of the thread grooves on the sliding seat 2 that are in threaded cooperation with the two distance-adjusting screws 3 are set to be opposite.

[0057] When adjusting the height of the formwork 16, rotate the distance-adjusting screw 3 by a preset number of turns according to the height from the ground that the bracket 1 needs to be adjusted. Due to the meshing transmission relationship of the two first gears 4, when one of the distance-adjusting screws 3 rotates, it will drive the other distance-adjusting screw 3 to rotate through the first gear 4 meshed with it, so that the rotation directions of the two distance-adjusting screws 3 are opposite, so that the two distance-adjusting screws 3 can simultaneously move downward relative to the sliding seat 2 to lift the bracket 1 and the formwork 16.

[0058] During the rotation of the distance adjustment screw 3, since the rotation directions of the two distance adjustment screws 3 are opposite, the torque directions generated by them during rotation on the sliding seat 2 are also opposite, so that the torques can be cancelled out with each other. By this torque cancellation method, the stability and reliability of the sliding seat 2 on the support 1 can be significantly improved.

[0059] In some other embodiments, when the existing height calibration device calibrates the height of the template 16, it generally uses manual or electric (electric wrench plus socket) methods, neither of which can accurately control the height calibration amount, and over-adjustment often occurs. Therefore, it is necessary to adjust repeatedly, which further exacerbates the local wear of the distance adjustment screw 3. At the same time, the locking method after adjustment is relatively simple, and the adjustment screw will be subjected to a frictional force perpendicular to the axis. In the long run, the thread on the surface of the adjustment screw will be damaged, further exacerbating the problem of uneven wear. In severe cases, the adjustment screw may even bend and become scrapped. To solve the above problems, the formwork adjustment device for building construction is further provided with an adjustment mechanism, and the adjustment mechanism is configured to be able to adjust the number of turns of rotation of the distance adjustment screw 3 according to the ground clearance height that the support 1 needs to adjust. In this way, during use, under the action of the adjustment mechanism, the number of turns of rotation of the distance adjustment screw 3 can be adjusted according to the ground clearance height that the support 1 needs to adjust, so as to reduce the error caused by manual adjustment and facilitate improving the adjustment accuracy.

[0060] Further, the adjustment mechanism is provided to include a mounting shell 501, a scale line 502, an adjustment part 503, a rack 504, a rotating shaft 505, a second gear 506, a locking rod 507, a locking positioning part 508, a mounting seat 509, a knob 5010, a third gear 5011 and a cutting component 5012. The mounting shell 501 is sleeved on the bottom ends of the two distance adjustment screws 3 together and is rotatably connected to the distance adjustment screws 3; the scale line 502 is arranged on the mounting shell 501 and is arranged along the extension direction perpendicular to the distance adjustment screw 3; the adjustment part 503 is inserted into the mounting shell 501 and can slide along the extension direction perpendicular to the distance adjustment screw 3 to move to the scale at the scale line 502 corresponding to the ground clearance height that the support 1 needs to adjust, and can elastically slide along the direction perpendicular to the plate surface of the template 16; the rack 504 is inserted into the mounting shell 501 and extends along the extension direction perpendicular to the distance adjustment screw 3 and is fixedly arranged on the adjustment part 503.

[0061] The rotating shaft 505 is vertically arranged inside the mounting shell 501, and the top end of the rotating shaft 505 is coaxially and fixedly arranged at the bottom end of one of the distance adjustment screws 3; the second gear 506 is fixedly sleeved on the rotating shaft 505 and can mesh with the rack 504; the locking rod 507 is vertically arranged inside the mounting shell 501, and the locking rod 507 can elastically slide along the extending direction of the distance adjustment screw 3 and has corresponding first and second positions before and after sliding. When in the first position, the locking rod 507 is inserted into the meshing part of the two first gears 4 to lock the two distance adjustment screws 3. When in the second position, the locking rod 507 is pulled out from the meshing part of the two first gears 4 to unlock the two distance adjustment screws 3; the locking and positioning part 508 is inserted into the mounting shell 501 and can elastically slide along the direction perpendicular to the extending direction of the distance adjustment screw 3. The locking and positioning part 508 is configured to lock the locking rod 507 in the second position, and when the position adjustment part 503 is at the zero scale on the scale line 502, the locking and positioning part 508 and the rack 504 form a stop fit and can unlock the locking of the locking and positioning part 508 on 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 into the mounting shell 501, sleeved on the knob 5010, and can slide relative to the knob 5010 along the extending direction of the distance adjustment screw 3; the third gear 5011 is sleeved on the mounting seat 509 and can both rotate synchronously with the knob 5010 and slide synchronously with the mounting seat 509 along the extending direction of the distance adjustment screw 3. When the third gear 5011 slides along the extending direction of the distance adjustment screw 3, it has corresponding third and fourth positions. When in the third position, the third gear 5011 is disengaged from the first gear 4. When in the fourth position, the third gear 5011 meshes with the first gear 4; the cutting position assembly 5012 is configured to be able to switch the positions of the locking rod 507 and the third gear 5011 simultaneously.

[0062] Specifically in this embodiment, as Figure 1 , Figure 3 , Figure 6 , Figure 7 , Figure 8 shown, the mounting shell 501 is set as a box structure, and the right side wall of the mounting shell 501 is arranged parallel to the plate surface of the template 16; the lower end of the distance adjustment screw 3 is rotatably inserted into the mounting shell 501 during installation; the first gear 4 is inserted into the mounting shell 501; the scale line 502 is arranged on the left side wall of the mounting shell 501 and extends in the front-back direction, and the front end of the scale line 502 is the zero scale.

[0063] To facilitate the installation of the position adjustment part 503, an installation hole is provided on the left side wall of the installation shell 501. The installation hole extends in the front-rear direction and is located below the scale line 502 to facilitate indicating the position adjustment distance of the position adjustment part 503. The position adjustment part 503 is arranged in a C-shaped structure and has a base strip and base rods located at both ends of the base strip. The base rods and the base strip are vertically arranged. When installed, the base strip extends in the front-rear direction and is located outside the installation shell 501 and can form a stop fit with the installation shell 501 to prevent the base rods from being inserted into the installation hole, resulting in the inability to achieve the position adjustment function of the position adjustment part 503. When installed, the base rods penetrate through the installation hole. With the cooperation of the two base rods and the installation hole, the position adjustment part 503 can slide in the front-rear direction. The rack 504 extends in the front-rear direction and is vertically connected to the ends of the two base rods away from the base strip at the same time. To facilitate the position adjustment part 503 to elastically slide in the direction perpendicular to the plate surface of the template 16, the formwork adjusting device for construction is further provided with two gaskets 14 and two second compression springs 15. The two gaskets 14 are respectively sleeved on the two base rods, inserted into the installation shell 501, and can form a stop fit with the inner side wall of the installation shell 501. The two second compression springs 15 are respectively sleeved on the two base rods, and both ends are respectively abutted between the gasket 14 and the rack 504. Under the action of the second compression spring 15, the position adjustment part 503 has a tendency to be inserted into the installation shell 501.

[0064] Optionally, the gasket 14 can be set as a round gasket.

[0065] Optionally, bearings can be provided at the lower end of each distance adjustment screw 3 above the first gear 4. The bearings are inserted into the installation shell 501 at the same time to improve the smoothness of the rotation of the distance adjustment screw 3.

[0066] Optionally, to facilitate the movement of the position adjustment part 503, a handle is provided in the middle of the left side wall of the base strip.

[0067] The rotating shaft 505 is vertically arranged in the installation shell 501 and is coaxially and fixedly arranged with the rear distance adjustment screw 3. The second gear 506 is fixedly sleeved on the lower end of the rotating shaft 505 and meshes with the rack 504. As Figure 11 shown, to facilitate the locking rod 507 to elastically slide along the extension direction of the distance adjustment screw 3, the adjusting mechanism is further provided with a third compression spring 5013. The third compression spring 5013 is vertically arranged in the installation shell 501 and is connected between the lower end of the locking rod 507 and the installation shell 501. Under the action of the third compression spring 5013, the locking rod 507 has an upward movement tendency. Figure 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.

[0068] To more clearly describe the positional relationship among the third compression spring 5013, the block 5081 and the slot 5071, as shown in FIG. Figure 11 As shown, Figure 11 The left side is the rear, Figure 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.

[0069] 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.

[0070] To more clearly describe the positional relationship between the knob 5010, the third gear 5011 and the mounting base 509, as shown in FIG. Figure 10 As shown, Figure 10 The left side is the rear, Figure 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.

[0071] Initially, the locking lever 507 is in the first position and is inserted into the meshing position of the two first gears 4 to lock the two distance adjusting screws 3; the third gear 5011 is in the third position, and the third gear 5011 is disengaged from the first gear 4 on the distance adjusting screw 3 at the front side.

[0072] During the height adjustment process, after the bracket 1 is installed on the formwork 16, first drive the positioning part 503 to move leftward. While compressing the second compression spring 15, disengage the rack 504 from the second gear 506. Then drive the positioning part 503 to move backward until the positioning part 503 moves to the scale position on the scale line 502 corresponding to the ground height that the bracket 1 needs to be adjusted. Then release the positioning part 503, and under the action of the second compression spring 15, the positioning part 503 moves rightward to make the rack 504 mesh with the gear again.

[0073] Then, through the switching component, the locking lever 507 is moved from the first position to the second position, and the third gear 5011 is moved from the third position to the fourth position. When the locking lever 507 is in the second position, the locking lever 507 is pulled out from the meshing position of the two first gears 4 to unlock the two distance adjusting screws 3. The third compression spring 5013 is in a compressed state. At the same time, the locking and positioning part 508 locks the locking lever 507 in the second position through the clamping between the clamping block 5081 and the clamping groove 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 meshes with the first gear 4 on the distance adjusting screw 3 at the front side.

[0074] Then rotate the knob 5010. The knob 5010 drives the third gear 5011 to rotate. The third gear 5011 drives the distance adjusting screw 3 at the front side to rotate through the meshing with the first gear 4 on the distance adjusting screw 3 at the front side. At the same time, the distance adjusting screw 3 at the front side drives the distance adjusting screw 3 at the rear side to rotate through the meshing between the first gear 4 on it and the first gear 4 on the distance adjusting screw 3 at the rear side, so that both distance adjusting screws 3 move downward relative to the sliding seat 2 to lift the bracket 1 and the formwork 16. On the other hand, it drives the second gear 506 to rotate through the rotating shaft 505, and the second gear 506 drives the positioning part 503 to move forward through the meshing with the rack 504.

[0075] When the position adjusting part 503 moves to a position where the rack 504 and the locking and positioning part 508 form a stop fit, as the knob 5010 continues to rotate, the position adjusting part 503 continues to move and drives the locking and positioning part 508 to move forward. While compressing the fourth compression spring 5014, the latch block 5081 and the card slot 5071 are disengaged from the snap connection. 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 part of the two first gears 4 to lock the two distance adjusting screws 3. At the same time, under the action of the switching component, the third gear 5011 moves from the fourth position to the third position to disengage from the first gear 4 on the distance adjusting screw 3 located on the front side, thereby realizing automatic locking, avoiding over-adjustment or under-adjustment, and ensuring the adjustment accuracy.

[0076] Further, the cutting component 5012 is set to include a shift lever 50121 and a lever 50122. The shift lever 50121 is inserted into the mounting shell 501 and extends along a direction perpendicular to the plate surface of the template 16 and can rotate around its own axis; the lever 50122 is vertically arranged with the shift lever 50121, and the middle part is fixedly sleeved on the shift lever 50121; the locking rod 507 and the mounting seat 509 are respectively hinged at both ends of the lever 50122.

[0077] Specifically, as Figure 7 shown, the shift 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 shift lever 50121. The middle part of the locking rod 507 is hinged at the rear end of the lever 50122, and the lower end of the mounting seat 509 is hinged at the front end of the lever 50122.

[0078] 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 is inserted into the meshing part of the two first gears 4 to lock the two distance adjusting screws 3; the third gear 5011 is in the third position, and the third gear 5011 is disengaged from the first gear 4 on the distance adjusting screw 3 located on the front side.

[0079] After the rack 504 is re-engaged with the second gear 506, rotate the shift lever 50121 to make the rear end of the lever 50122 low and the front end high, as Figure 7 shown. At this time, the locking rod 507 is in the second position and is disengaged from the meshing part of the two first gears 4 to unlock the two distance adjusting screws 3. The third compression spring 5013 is in a compressed state. At the same time, the locking and positioning part 508 locks the locking rod 507 in the second position through the snap connection between the latch block 5081 and the card 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 distance adjusting screw 3 located on the front side.

[0080] As the positioning part 503 moves, when the clamping block 5081 disengages from the clamping groove 5071, under the action of the third compression spring 5013, the locking lever 507 moves from the second position to the first position. The locking lever 507 synchronously drives the third gear 5011 to move downward through the lever 50122, so as 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.

[0081] In a further embodiment, to improve the convenience of rotating the dial lever 50121, it is provided that the formwork adjusting device for construction also includes a pushing part 6. The pushing part 6 is arranged on the dial lever 50121 and is located outside the installation shell 501.

[0082] Specifically in this embodiment, as Figure 3 and Figure 7 shown, the pushing part 6 is arranged in a strip structure and is vertically arranged at the left end of the dial lever 50121. The pushing part 6 and the dial lever 50121 together form an L-shaped structure. In this way, when it is necessary to rotate the dial lever 50121, the dial lever 50121 can be driven to rotate by manually moving the pushing part 6.

[0083] In other embodiments, when the existing height adjustment device adjusts the height of the formwork 16, the adjusting screw will gradually tilt under the support of the ground, resulting in the inability to form a stable support between the adjusting screw and the ground. And because the adjusting screw is approximately in point contact with the ground, under the gravity of the formwork 16, the adjusting screw may slip, which will not only affect the accuracy of the subsequent height adjustment of the formwork 16, but also affect the stable support of the formwork 16. To solve the above problems, it is provided that the formwork adjusting device for construction also includes a support base 7. The support base 7 is hinged at the bottom of the installation shell 501 and supports on the ground during use.

[0084] Specifically in this embodiment, as Figure 4 shown, the support base 7 is arranged in a flat plate structure, and the top of the support base 7 is hinged at the bottom of the installation shell 501. In this way, when the distance adjusting screw 3 extends downward relative to the sliding seat 2, due to the hinge setting, the support base 7 can keep in surface contact with the ground, so as to ensure the support stability of the formwork 16.

[0085] In some other embodiments, it is provided that the bracket 1 is detachably connected to the formwork 16 by screws.

[0086] Specifically in this embodiment, the number of screws can be set to four, and they are respectively arranged at the four corners of the bracket 1. In this way, the bracket 1 can be fixed on the formwork 16 by tightening the screws.

[0087] In some other embodiments, to achieve one-way cooperation between the support 1 and the sliding seat 2, it is provided that the formwork adjusting device for building construction further includes a first ratchet 8 and a second ratchet 9. The first ratchet 8 is arranged on the support 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 one-way cooperation with the first ratchet 8.

[0088] Specifically in this embodiment, as Figure 5 shown, Figure 5 the left side in Figure 5 corresponds to the right side, and the right side in

[0089] corresponds to the left side. The first ratchet 8 is arranged on the right plate surface of the support 1, and the inclined surface of the first ratchet 8 extends along the lower right direction. 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 along 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 relative to the support 1 in the vertical direction.

[0089] In some other embodiments, to both improve the support effect on the formwork 16 and reduce the wear of the screws or the first bolts and first nuts, it is provided that the support 1 includes a side plate and a bottom plate arranged vertically. The plate surface of the side plate coincides with the plate surface of the formwork 16 during use, and the bottom plate supports the bottom of the formwork 16.

[0090] Specifically in this embodiment, the support 1 is arranged in an L-shaped structure. In this way, the setting of the bottom plate can share part of the gravity of the formwork 16, so that the load originally concentrated on the connecting components (screws or the first bolts and first nuts) is effectively dispersed. In this way, not only can the overall support effect on the formwork 16 be improved, ensuring the stability and reliability of the formwork 16 during construction, but also the wear of connecting components such as screws or the first bolts and first nuts can be significantly reduced, extending their service life and reducing construction costs.

[0091] The technical features of the above embodiments can be combined arbitrarily. For the sake of brief description, 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, it should be considered as the scope recorded in this specification.

[0092] The above-described embodiments only represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
