Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of building construction equipment, and particularly relates to a formwork construction precision adjustable vertical support rod, which is suitable for formwork support of a culvert top and can effectively cope with the downward deflection of the top plate after concrete pouring. BACKGROUND

[0002] In the process of building construction, the vertical support rod (also known as a top support, a formwork support rod, etc.) is an important equipment for supporting the formwork, ensuring construction safety and structural stability. However, the conventional support rod has the following disadvantages in practical application:

[0003] 1. Difficult to adjust, low efficiency.

[0004] For example, a threaded adjustment type support rod: the height is adjusted by rotating a nut or a sleeve. It needs to be rotated multiple times, which is time-consuming and laborious, especially when fine adjustment is needed, the efficiency is low. A pin adjustment type support rod: a plurality of fixed holes are arranged on the steel pipe, and the height is positioned by a pin. The hole distance is usually large (such as 10 cm or 20 cm), which cannot meet the demand of accurate adjustment.

[0005] 2. Difficult to disassemble, with safety hazards.

[0006] After the concrete pouring is completed, the floor slab or the formwork may be deflected downward (bent downward) due to the load. When the conventional support rod is disassembled, it is difficult to disassemble due to the interaction of the support force and the deflection force, and forcibly disassembling may cause structural damage or safety accidents.

[0007] 3. Poor adaptability, low standardization.

[0008] Different construction scenes need vertical support rods of different lengths, and the conventional vertical support rod lacks standardized design, cannot flexibly adapt to different height requirements, and increases the complexity of equipment management and construction organization.

[0012] As a preferred scheme, the clamping groove disc includes a circular base plate, a support boss provided on the upper surface of the circular base plate, and a clamping groove part provided on the lower surface of the circular base plate. A reserved hole is provided in the center of the circular base plate to allow the push rod to pass through. The push plate is placed on the support boss. The clamping groove part has a H-shaped structure, so that the notch at one end of the fastening plate can be clamped on the H-shaped structure.

[0013] As a preferred scheme, the one end of the fastening plate provided with the notch is fastened to the clamping groove part by friction. The other end stretched out from the lateral wall of the sleeve pipe can release the fastening of the fastening plate. The support force on the push rod disappears, and the push rod returns to the original position under the support of the spring.

[0014] As a preferred scheme, standardized holes are provided on the pipe walls of the intermediate pipe and the top end pipe at intervals. A pair of standardized holes of the intermediate pipe and the top end pipe are fixed by a latch pin, so as to achieve rough height adjustment.

[0015] As a preferred scheme, the end of the latch pin is provided with a bent part. The bent part can prevent the latch pin from coming out after passing through the standardized hole.

[0016] As a preferred scheme, one standardized hole is provided on the pipe walls of the intermediate pipe and the top end pipe at every 10 cm interval.

[0017] As a preferred scheme, the intermediate pipe and the top end pipe are designed in a standardized manner and have multiple length specifications. They can be combined to meet different height requirements.

[0018] As a preferred scheme, the depth of the footboard is adjusted to adjust the rising amplitude of the push rod, so as to achieve millimeter-level precision adjustment.

[0019] As a preferred scheme, the construction formwork is a culvert top formwork, and the support plate supports the deflection of the culvert top formwork after the concrete is poured.

[0020] As a preferred scheme, the support plate is designed according to the construction requirements to increase the contact area with the construction formwork and uniformly disperse the load.

[0021] Compared with the prior art, the utility model has at least the following beneficial effects:

[0022] The smooth push rod system is provided, so that the height fine adjustment of the support rod is no longer dependent on the traditional coarse adjustment mode, but is steplessly adjusted through accurate foot pedal operation, greatly improving the accuracy and meeting the needs of high-precision construction scenes. The traditional support rod adjustment mode cannot provide such fine adjustment capability, especially in high-strength construction and special formwork support, the improvement of accuracy can effectively guarantee the structural safety. At the same time, the traditional support rod usually needs multiple operation steps to complete the adjustment, such as rotating the nut, adjusting the latch, etc. These operations not only take time and effort, but also are prone to errors. The utility model directly adjusts the height of the support rod through foot pedal operation, without the need to frequently replace the latch or rotate the nut, and the operation is simple and intuitive, and the support rod height can be quickly adjusted each time the foot pedal is stepped on, which significantly improves the work efficiency, and is particularly suitable for construction scenes that need to frequently adjust the height. By using the foot pedal to adjust the height, the operator can focus on the stable operation of the support rod with both hands, rather than the tedious details in the adjustment process. Since both hands can hold the support rod for stable operation, it can ensure that the support rod does not shake or become unstable during the adjustment process, thereby providing higher safety and stability. Compared with the traditional manual rotation or latch adjustment mode, using the foot pedal operation not only improves the accuracy of the adjustment, but also enhances the stability of the entire process, reducing the operation risk. On the other hand, the traditional support rod may cause structural damage or safety hazards during the disassembly process due to the interaction between the support force and the load. The utility model releases the clamping plate, and the push rod can be slowly retracted. This design not only ensures the safety of the construction personnel, but also effectively reduces the damage to the structure during the disassembly of the support rod, improving the safety and work efficiency of the construction site. The support rod of the utility model has strong adaptability and is suitable for various construction scenes such as culvert formwork support. Through standardized design, the support rod can be flexibly combined to meet different height requirements without the need for additional customization or replacement of equipment. This makes the utility model efficient in different construction environments, reducing the complexity of equipment management and construction organization. BRIEF DESCRIPTION OF DRAWINGS

For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0044] The utility model aims at solving the problems of insufficient adjustment accuracy, complicated operation, difficult disassembly and poor adaptability of the existing vertical support equipment in building construction. When the height of the traditional support rod is adjusted, the operator needs to manually rotate the nut or frequently pull out and insert the bolt, which not only consumes time and effort, but also makes it difficult to achieve accurate control of the height, reducing the construction efficiency. Especially after the completion of concrete pouring, the top plate may be deflected downward, the stress on the support rod increases, and the disassembly becomes more difficult, even with potential safety hazards. The utility model applies the smooth push rod principle to the design of the support rod, combines with the independent foot pedal lifting device and the tightening plate, realizes stepless accurate adjustment of the height and convenient disassembly operation, greatly improves the construction efficiency and safety, and is suitable for various construction scenes such as culvert formwork setting and support.

[0045] The utility model embodiment template construction precision adjustable vertical support rod, including top tube 1, middle tube 2 and smooth push rod system 3. Further, please refer toFigure 6 As shown in Figures 7(a) to 7(f), the smooth push rod system 3 includes an outer sleeve 31, a push rod 32, a push plate 33, a slotted plate 34, a clamping plate 35, a foot pedal 36, and a spring 37. Figure 1 As shown, the top tube 1, the middle tube 2, and the outer tube 31 are nested in sequence. Referring to Figures 2(a) and 2(b), the slot plate 34 is fixed inside the outer tube 31.

One end of the clamping plate 35 has a notch that engages with the slot in the slot plate 34, while the other end extends from the side wall of the outer tube 31. A pre-drilled hole is provided in the center of the push plate 33 to allow the push rod 32 to pass through and is placed on the upper side of the slot plate 34. The middle part of the foot pedal 36 is connected to the outer tube 31 via a pivot. One end of the foot pedal 36 extends into the space between the push plate 33 and the slot plate 34, while the other end extends from the side wall of the outer tube 31.

[0046] In this embodiment of the invention, the foot pedal 36 is not connected to the push plate 33 or the retaining plate 34. When the foot pedal 36 is pressed, the other end of the foot pedal 36 lifts the push plate 33, thereby compressing the first spring. The rise of the push plate 33 causes the push rod 32 to rise. The retaining plate 34 is fixed to the outer sleeve 31 and will not move. When the foot pedal 36 is released, the clamping plate 35 generates a clamping force, thereby fixing the position of the push rod 32.

The slot portion has an I-shaped structure so that the notch at one end of the clamping plate 35 can be locked onto the I-shaped structure.

[0049] Please refer to Figures 8(a) and 8(b). In this embodiment of the invention, the clamping plate 35 with a notch is clamped to the slot through friction. Lifting the other end extending from the side wall of the outer sleeve 31 releases the clamping plate 35, eliminating the supporting force on the push rod 32. The push rod 32 then returns to its original position under the support of the spring 37.

After the concrete is poured, the support plate supports the downward deflection of the culvert top formwork 5. Furthermore, the surface shape of the support plate is designed according to construction requirements. It can be a plane, a groove, or other specific shape to increase the contact area with the construction template, evenly distribute the load, and ensure the stability and safety of the support. Especially during the concrete pouring and dismantling process, it reduces the hidden dangers caused by local stress concentration.

[0053] The support rod of this utility model is designed using a smooth push rod principle and a foot pedal fine-tuning system. The specific working principle is as follows:
