Description

Technical Field

[0001] The present invention relates to the technical field of building construction formwork support, and in particular to an auxiliary support mechanism and method for building construction. Background Art

[0002] Formwork supports play a role in supporting and stabilizing the formwork during the construction process, ensuring that the formwork can maintain its shape and withstand the corresponding load when pouring concrete or other materials. Since some formwork will collapse when pouring concrete, adjustable top supports are required to reinforce this part of the formwork.

[0003] The existing top support is a single support, which has poor stability and is easy to fall over when subjected to lateral force. Therefore, the publication number CN119332922A discloses a top plate formwork support assembly, which includes a support positioning tube and an upper top support tube, as well as a top support height adjustment mechanism, a beam-column top support mechanism and a main body bearing mechanism. An upper top support tube is arranged above the support positioning tube, and the support positioning tube and the upper top support tube are connected through a top support height adjustment mechanism. A beam-column top support mechanism is arranged in the middle of the top end of the upper top support tube, and a main body bearing mechanism is arranged at the bottom end of the support positioning tube.

[0004] The above-mentioned top plate formwork support assembly is provided with a top support height adjustment mechanism. By turning the hand wheel, the worm and the turbine drive the horizontal transmission gear and the lifting top support screw to rotate, so that the top connecting ring drives the upper top support pipe to rise, thereby quickly adjusting the height of the support structure. Compared with the original device, the lifting structure is combined to the middle and surface of the support positioning pipe and the upper top support pipe, which greatly reduces the overall footprint of the device. At the same time, a flip support rod is provided to support the support positioning pipe, thereby increasing the force area between the support positioning pipe and the floor slab, making the support positioning pipe more stable.

[0005] When the above-mentioned support assembly is used in specific situations, the structure is complex and cannot meet the requirements of actual scenarios. At the same time, a flip support rod is used to provide support for the support positioning tube. However, since the flip support rod is located at the bottom of the support positioning tube, according to the force decomposition, the lateral support force of the flip support rod on the support positioning tube is relatively small, which cannot meet the normal support requirements of the support positioning tube. In addition, the maximum adjustable height is the total length of the support positioning tube, and the length adjustment is limited. At the same time, if the top plate is uneven or tilted at a certain angle, the supporting effect of the above-mentioned support assembly is reduced and cannot meet the requirements of different top plates.

[0006] Therefore, a new auxiliary support mechanism based on building construction can be used to solve the shortcomings of the existing technology. Summary of the Invention

[0007] The purpose of the present invention is to solve the problems existing in the prior art and to propose an auxiliary support mechanism and method for building construction.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] An auxiliary support mechanism for building construction, comprising a plurality of support columns and square steel, and a support assembly mounted on each support column;

[0010] Two adjacent support columns are connected and locked by multiple transverse support rods and connecting sleeves. Each support assembly has multiple degrees of freedom adjustment and is used to support building roofs with different inclinations.

[0011] The plurality of support assemblies are divided into two mutually cooperating support groups, the square steel is placed on the two cooperating support assemblies, and a lifting assembly with two-stage adjustment is installed between each support assembly and the corresponding support column for adjusting the height of the support assembly;

[0012] A force unloading assembly is installed between the two matching support assemblies and the corresponding transverse support rods to transfer the oblique pressure borne by the top of the support assembly and reduce the probability of deformation of the lifting assembly.

[0013] Preferably, each of the support columns is provided with a plurality of circular holes, and each of the connecting sleeves is locked to the corresponding support column via the circular holes and the plugs.

[0014] Preferably, the support assembly includes a rotating disk, a second rotating shaft is fixedly mounted on the rotating disk, a rotating block is rotatably mounted on the second rotating shaft, a limiting U-shaped plate is fixedly mounted on the rotating block, a first rotating shaft is fixedly mounted on the limiting U-shaped plate, and a pad is rotatably mounted on the first rotating shaft.

[0015] Preferably, the rotating block is circular, a plurality of supporting blocks that abut against the rotating block are fixedly mounted on the rotating disk, the bottom of the pad is designed in an arc shape, and the bottom of the pad abuts against the limiting U-shaped plate.

[0016] Preferably, the lifting assembly includes a first screw slidably mounted inside a support column, and the first screw is hollow, a second screw is slidably mounted inside the first screw, a threaded ring rotatably mounted on the support column through a support bearing is rotatably connected to the first screw thread, a first nut rotatably mounted on the first screw is rotatably connected to the second screw thread, a linkage mechanism is installed between the first nut and the threaded ring, and the rotating disk is rotatably connected to the first screw.

[0017] Preferably, the linkage mechanism includes a rotating ring fixedly mounted on the first nut, and both the rotating ring and the threaded ring are provided with a slot, and a second telescopic rod is fixedly mounted in the two matching slots.

[0018] Preferably, two first telescopic rods with return springs installed inside are fixedly mounted on the threaded ring.

[0019] Preferably, the unloading assembly includes a connecting ring rotatably mounted on the corresponding two rotating disks, a horizontal frame is fixedly mounted on the two connecting rings, a corrugated arc plate is placed on the horizontally arranged horizontal support rod located at the top, an inner corrugated locking sleeve that cooperates with the corrugated arc plate is provided on the horizontal support rod, and an adjustment mechanism is installed between the inner corrugated locking sleeve and the horizontal frame.

[0020] Preferably, the adjustment mechanism includes a second rotating plate rotatably mounted on the horizontal frame, and a first rotating plate rotatably mounted on the inner corrugated locking sleeve, a sleeve is fixedly mounted on the first rotating plate, a third screw is slidably mounted in the sleeve, a second nut rotatably connected to the third screw thread is rotatably mounted on the sleeve, and the third screw is fixedly connected to the second rotating plate.

[0021] The present invention also provides an auxiliary support method for building construction, comprising the above-mentioned auxiliary support mechanism for building construction, and further comprising the following steps:

[0022] S1. First, multiple support columns are spliced ​​together through connecting sleeves to form a rectangular closed ring. Then, the entire mechanism is moved to the bottom of the top plate to be supported, and square steel is placed on the support assembly;

[0023] S2. After the mechanism is placed, the height of the support assembly is adjusted by the lifting assembly so that the square steel on the support assembly is against the top plate. When the square steel and the top plate are about to touch each other, the gap between the top plate and the square steel is observed. Then, the direction of the support assembly is adjusted so that the angle of the square steel can be automatically changed when the square steel and the top plate touch each other, so that the square steel and the top plate are in close contact.

[0024] S3. After the square steel and the top plate are in contact, the unloading assembly is adjusted according to the inclination angle of the square steel so that the unloading assembly is perpendicular to the square steel, and the inclination pressure on the square steel is transferred to the horizontal support rods and support columns. At this time, the force point is lower, the stability is higher, and the probability of bending of the support assembly and the lifting assembly is reduced.

[0025] Compared with the existing technology, the advantages of the present invention are:

[0026] 1. When supporting the top plate, the auxiliary support mechanism for building construction forms a rectangular support system by setting multiple support columns and transverse support rods, which has higher support stability. At the same time, the use of connecting sleeves makes the disassembly and assembly of the rectangular support system more convenient.

[0027] 2. When the auxiliary support mechanism for the construction of this building supports the top plate, the first screw and the second screw are set so that the height adjustment of the limit U-shaped plate exceeds the length of the support column, and the height adjustment range is larger. In addition, the adjustment of the first screw and the second screw requires the provision of a threaded ring and a first nut. In this way, the vertical force support point is changed from the original single nut to two nuts, which has higher force support and reduces the probability of the screw and nut slipping. In addition, the force on the single nut is reduced, and the pressure between the nut and the screw is reduced, making the nut easier to rotate after the construction is completed.

[0028] 3. When the auxiliary support mechanism for building construction is supporting the top plate, a second telescopic rod is set to drive the first screw and the second screw to move synchronously, so that the height adjustment displacement of the U-shaped plate limited by a single rotation of the threaded ring is larger, the number of rotations of the threaded ring is reduced, and the adjustment efficiency is higher. At the same time, the second telescopic rod can also distribute the bending moment on the first screw, reducing the probability of bending and deformation of the first screw.

[0029] 4. When the auxiliary support mechanism for building construction is supporting the top plate, an adjustment mechanism that can freely change the angle and length of the unloading component is set to offset the bending moment of the second screw and transmit the pressure of the second screw to the transverse support rod, thereby improving the stability of the second screw and reducing the probability of the second screw bending.

[0030] To sum up, the present invention adopts a twin-screw lifting method to adjust the support height, expand the adjustment range, effectively reduce the number of adjustment circles, and improve the adjustment efficiency. At the same time, the twin-screw has dual support points, the support area is expanded, the support stability is higher, and the service life is longer. In addition, when supporting the inclined surface, the inclination pressure generated by the inclined surface is transferred, the probability of the screw bending is reduced, the overall support center of gravity is reduced, and the stability is higher.

DETAILED DESCRIPTION

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] Example 1: Reference Figures 1-11 , an auxiliary support mechanism for building construction, comprising a plurality of support columns 1 and square steels 2, and also comprising a support assembly 7 mounted on each support column 1;

[0049] Each support column 1 is provided with a plurality of circular holes, and each connecting sleeve 6 is locked to the corresponding support column 1 through the circular holes and the plug;

[0050] The connecting sleeve 6 adopts a splicing design. Each connecting sleeve 6 is composed of two semicircular pipe sleeves. The two pipe sleeves are fixedly connected by snapping. This is a common splicing method, so it will not be explained in detail here. Since it is a common technology, the accompanying drawings do not show it in detail.

[0051] The purpose of the design of the connecting sleeve 6 is to facilitate the installation and disassembly of the whole, which not only improves the overall stability when in use, but also allows for disassembly and storage when not in use, thus reducing the floor space.

[0052] The purpose of using the square steel 2 to contact the building structure is to increase the contact area between the square steel 2 and the building structure, thereby reducing the force per unit area and making the support more stable.

[0053] Two adjacent support columns 1 are connected and locked by multiple transverse support rods 3 and connecting sleeves 6. Each support assembly 7 has multiple degrees of freedom adjustment and is used to support building roofs with different inclinations.

[0054] The multiple support assemblies 7 are divided into two groups of mutually cooperating support groups. The square steel 2 is placed on the two groups of cooperating support assemblies 7. A lifting assembly 4 with two-stage adjustment is installed between each group of support assemblies 7 and the corresponding support column 1 to adjust the height of the support assembly 7.

[0055] The lifting assembly 4 includes a first screw 8 slidably mounted inside the support column 1, and the first screw 8 is hollow. A second screw 9 is slidably mounted inside the first screw 8. A threaded ring 10 is rotatably mounted on the support column 1 through a support bearing 22 and is threadedly connected to the first screw 8. A first nut 15 is rotatably mounted on the first screw 8 and is threadedly connected to the second screw 9. A linkage mechanism is installed between the first nut 15 and the threaded ring 10, and a rotating disk 17 is rotatably connected to the first screw 8.

[0056] The function of the support bearing 22 is to make the threaded ring 10 rotate more smoothly.

[0057] When the height of the support assembly 7 needs to be adjusted, it is only necessary to rotate the threaded ring 10. The rotation of the threaded ring 10 will drive the first screw 8 to slide upward in the support column 1, thereby adjusting the height of the upper end of the first screw 8;

[0058] Rotating the first nut 15 will drive the second screw rod 9 to move upward inside the first screw rod 8 , thereby changing the height of the top of the second screw rod 9 .

[0059] The linkage mechanism includes a rotating ring 11 fixedly mounted on the first nut 15. The rotating ring 11 and the threaded ring 10 are both provided with a slot, and a second telescopic rod 14 is fixedly mounted in the two matching slots.

[0060] During the rotation of the threaded ring 10, the first nut 15 is driven to rotate by the second telescopic rod 14, so that the threaded ring 10 and the first nut 15 rotate synchronously, thereby driving the first screw 8 and the second screw 9 to rise synchronously. Compared with the original single screw adjustment, the double screw adjustment rotates the same number of times, and the height adjustment is twice the original. Therefore, when adjusting the same height, the threaded ring 10 rotates half the number of times, which makes the adjustment faster.

[0061] At the same time, since the vertical force on the first screw 8 and the second screw 9 is shared by the threaded ring 10 and the first nut 15, the pressure on the first screw 8 and the second screw 9 is half of the original, the probability of the first screw 8 and the second screw 9 slipping is reduced, and the stability is higher.

[0062] The second telescopic rod 14 is connected to the threaded ring 10 and the rotating ring 11 in a snap-fit ​​manner. This connection method is more convenient for disassembly and installation.

[0063] At the same time, the second telescopic rod 14 is provided to distribute the bending moment on the first screw rod 8, thereby reducing the probability of bending and deformation of the first screw rod 8. When the first screw rod 8 is subjected to inclined pressure, the first screw rod 8 has a tendency to bend. At this time, the second telescopic rod 14 will support the first screw rod 8 on the side of the bending tendency, and stretch the first screw rod 8 on the side of the original bending, thereby transmitting part of the pressure to the second telescopic rod 14 and the support column 1, thereby improving the stability of the first screw rod 8 and extending the service life of the first screw rod 8.

[0064] Two first telescopic rods 13 with return springs installed inside are fixedly mounted on the threaded ring 10; when the square steel 2 is fixed on the building structure, the threaded ring 10 is rotated to drive the first screw rod 8 to move upward. At this time, under the action of the resistance force, the force required to rotate the threaded ring 10 increases. Therefore, in order to reduce the force applied by the operator, a retractable first telescopic rod 13 is used. According to the balance of forces, the longer the lever arm, the smaller the force applied. Therefore, the first telescopic rod 13 is extended, and the thrust acting on the first telescopic rod 13 is reduced. Therefore, the force applied by the operator is reduced, which makes it easier to rotate the threaded ring 10. After releasing the hand, the first telescopic rod 13 is reset under the action of the return spring.

[0065] The support assembly 7 includes a rotating disk 17, on which a second rotating shaft 21 is fixedly mounted, a rotating block 19 is rotatably mounted on the second rotating shaft 21, a limiting U-shaped plate 12 is fixedly mounted on the rotating block 19, a first rotating shaft 20 is fixedly mounted on the limiting U-shaped plate 12, and a pad 16 is rotatably mounted on the first rotating shaft 20. The pad 16 has an anti-skid groove on its surface for increasing the friction between the square steel 2 and the pad 16, thereby making the square steel 2 more stable;

[0066] First, rotate the rotating disk 17 to align the two limiting U-shaped plates 12, then place the square steel 2 on the two limiting U-shaped plates 12, and use the lifting assembly 4 to adjust the height of the square steel 2 so that the square steel 2 is offset from the building structure;

[0067] Since the bottom of some building structures is not flat, by rotating the threaded ring 10, the heights of the two matching limiting U-shaped plates 12 in each group are different. At this time, the square steel 2 is in an inclined state. Once the square steel 2 is tilted, the bottom of the square steel 2 will be against the edge end of the limiting U-shaped plate 12. At this time, the force point is a straight line at the end, and the force point is small. The limiting U-shaped plate 12 and the rotating block 19 are welded, so the welding part will be detached and cracked. Therefore, a pad 16 that can be rotated on the limiting U-shaped plate 12 is provided, which not only increases the contact area between the limiting U-shaped plate 12 and the square steel 2, but also transfers the force point to the middle position of the limiting U-shaped plate 12, so that cracking can be effectively avoided at the welding point between the limiting U-shaped plate 12 and the rotating block 19.

[0068] The rotating block 19 is circular, and a plurality of support blocks 18 that are against the rotating block 19 are fixedly installed on the rotating disk 17. The bottom of the pad 16 adopts an arc-shaped design, and the bottom of the pad 16 is against the limiting U-shaped plate 12; the arc design of the bottom of the pad 16 is used to ensure that the pad 16 rotates within a certain range, and the bottom of the pad 16 will be against the limiting U-shaped plate 12 to avoid the first rotating shaft 20 from being subjected to force, thereby ensuring smooth rotation of the pad 16.

[0069] The purpose of designing the support block 18 here is to distribute the pressure on the second rotating shaft 21, reduce the probability of deformation of the second rotating shaft 21, and make the rotating block 19 rotate more smoothly on the second rotating shaft 21. At the same time, it increases the transmission area between the rotating block 19 and the rotating disk 17, improves the conduction of force, and can better protect the second rotating shaft 21.

[0070] Example 2: This example differs from the example 1 in that: Figure 1-Figure 5 、 Figure 12-14 A force unloading assembly 5 is installed between the two matching support assemblies 7 and the corresponding transverse support rods 3 to transmit the oblique pressure borne by the top of the support assembly 7 and reduce the probability of deformation of the lifting assembly 4.

[0071] The unloading assembly 5 includes a connecting ring 23 rotatably mounted on the corresponding two rotating disks 17. A cross frame 24 is fixedly mounted on the two connecting rings 23. A corrugated curved plate 25 is placed on the top horizontally arranged transverse support rod 3. The transverse support rod 3 is provided with an inner corrugated locking sleeve 26 that cooperates with the corrugated curved plate 25. An adjustment mechanism 27 is installed between the inner corrugated locking sleeve 26 and the cross frame 24.

[0072] The length of the corrugated curved plate 25 is the same as that of the horizontal support rod 3 at the top. The corrugated curved plate 25 only needs to be placed on the horizontal support rod 3. The two ends of the corrugated curved plate 25 are supported by the support column 1, so no left and right displacement will occur.

[0073] The adjustment mechanism 27 includes a second rotating plate 29 rotatably mounted on the cross frame 24, and a first rotating plate 28 rotatably mounted on the inner corrugated locking sleeve 26. A sleeve 30 is fixedly mounted on the first rotating plate 28, and a third screw 32 is slidably mounted within the sleeve 30. A second nut 31 is rotatably mounted on the sleeve 30 and is threadably connected to the third screw 32. The third screw 32 is fixedly connected to the second rotating plate 29.

[0074] First, lift the inner corrugated locking sleeve 26 upward to separate the inner corrugated locking sleeve 26 from the corrugated curved plate 25, and then adjust the position of the inner corrugated locking sleeve 26. During the adjustment process, rotate the second nut 31, and under the action of the second nut 31, drive the third screw 32 to move, so as to adjust the distance between the first rotating plate 28 and the second rotating plate 29. Then loosen the inner corrugated locking sleeve 26 to make the inner corrugated locking sleeve 26 stuck on the corrugated curved plate 25, and continue to rotate the second nut 31 to make the inner corrugated locking sleeve 26 stuck to the corrugated curved plate 25.

[0075] Once the square steel 2 abuts against the top of the building structure, the vertical distance between the corrugated curved plate 25 and the cross frame 24 is fixed, so the distance between the first rotating plate 28 and the second rotating plate 29 increases, causing the first rotating plate 28 and the second rotating plate 29 to rotate, thereby changing the inclination angle of the sleeve 30. The inclination angle of the sleeve 30 is controlled according to the inclination of the top of the building structure. The larger the inclination angle, the greater the support force for the second screw 9 and the higher the stability.

[0076] By setting an adjustment mechanism 27 in the unloading assembly 5 that can freely change the angle and length, the bending moment applied to the second screw 9 is offset, and the pressure applied to the second screw 9 is transmitted to the transverse support rod 3, thereby improving the stability of the second screw 9 and reducing the probability of the second screw 9 bending.

[0077] The specific operating steps of this device are as follows:

[0078] First, multiple support columns 1 are spliced ​​together through the connecting sleeve 6 to form a rectangular closed ring. Then, the entire mechanism is moved to the bottom of the top plate to be supported. The rotating disk 17 is rotated to align the two limiting U-shaped plates 12. Then, the square steel 2 is placed on the two limiting U-shaped plates 12, and the square steel 2 is placed on the limiting U-shaped plates 12;

[0079] After the mechanism is placed, rotate the threaded ring 10. The rotation of the threaded ring 10 will drive the first screw 8 to slide upward in the support column 1. In the process of rotating the threaded ring 10, the first nut 15 will be driven to rotate through the second telescopic rod 14, so that the threaded ring 10 and the first nut 15 can rotate synchronously, thereby driving the first screw 8 and the second screw 9 to rise synchronously. When the square steel 2 is about to touch the top plate, observe the gap between the top plate and the square steel 2. Or after one end of the square steel 2 touches the top plate, adjust the angle of the square steel 2 by rotating the threaded ring 10 at the end that does not touch the top plate, so that the longitudinal angle of the square steel 2 and the top plate changes at this time. At the same time, the rotating disk 17 can rotate freely on the second screw 9, so the inclination angle can be automatically changed according to the horizontal flatness of the top plate, so that the square steel 2 is in close contact with the top plate.

[0080] After the square steel 2 abuts against the top plate, the inner corrugated locking sleeve 26 is lifted upward to separate the inner corrugated locking sleeve 26 from the corrugated curved plate 25, and then the position of the inner corrugated locking sleeve 26 is adjusted. During the adjustment process, the second nut 31 is rotated, and the third screw 32 is driven to move under the action of the second nut 31, so as to adjust the distance between the first rotating plate 28 and the second rotating plate 29. Then, the inner corrugated locking sleeve 26 is loosened to make the inner corrugated locking sleeve 26 stuck on the corrugated curved plate 25, and the second nut 31 is continued to be rotated to make the inner corrugated locking sleeve 26 stuck to the corrugated curved plate 25;

[0081] Once the square steel 2 abuts against the top of the building structure, the vertical distance between the corrugated curved plate 25 and the cross frame 24 is fixed, so the distance between the first rotating plate 28 and the second rotating plate 29 increases, causing the first rotating plate 28 and the second rotating plate 29 to rotate, thereby changing the inclination angle of the sleeve 30. The inclination angle of the sleeve 30 is controlled according to the inclination of the top of the building structure. The larger the inclination angle, the greater the support force for the second screw 9 and the higher the stability.

[0082] At this time, the longitudinal pressure is unloaded, and the lateral pressure cannot be unloaded by the unloading component 5. Therefore, when the entire mechanism is placed, the square steel 2 needs to be arranged along the inclined surface.

[0083] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
