[0024] Figure 1 This is a schematic diagram of the first embodiment of the template support frame with adjustable elevation according to this utility model.

[0025] Figure 2 This is a structural schematic diagram of the second embodiment of the template support frame with adjustable elevation according to this utility model.

[0026] Figure 3 This is a structural schematic diagram of the third embodiment of the template support frame with adjustable elevation according to this utility model. Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] See Figure 1 This utility model provides a template support frame with adjustable elevation. It combines two height adjustment methods through a positioning pin and threaded connection, achieving precise elevation adjustment. The entire adjustment process is easy to operate and suitable for widespread use. The following description, in conjunction with the accompanying drawings, illustrates this utility model's template support frame with adjustable elevation.

[0029] See Figure 1 This image shows a structural schematic diagram of the first embodiment of the template support frame with precisely adjustable elevation according to this utility model. The following is in conjunction with... Figure 1 This invention describes the template support frame with adjustable elevation.

[0030] like Figure 1As shown, the template support frame with adjustable elevation of this utility model includes a support tube 21, a support rod 22, a positioning pin 23, and an adjusting sleeve 24. The support tube 21 has openings at both ends and is vertically oriented. An insertion hole 211 is provided near the top opening of the support tube 21. The support rod 22 is inserted into the support tube 21, and pin holes 221 are provided at intervals on the support rod 22. A portion of the support rod 22 extends out from the top opening of the support tube 21, and a threaded connection section 222 is provided at the end of the support rod 22 extending out of the support tube 21. The length of the threaded connection section 222 is greater than the length of the support tube 21. The distance between two adjacent pin holes 221 and the length of the extended part of the support rod 22 are adjustable; the positioning pin 23 can be inserted into the insertion hole 211 on the support tube 21 and the corresponding pin hole 221 on the support rod 22, and the positioning pin 23 can connect the support rod 21 and the support tube 22; the adjusting sleeve 24 is threadedly connected to the threaded connection section 222, and the top of the adjusting sleeve 24 is provided with a template support surface 241. By rotating the adjusting sleeve 24, the adjusting sleeve 24 can be moved up and down relative to the support rod 22. The height adjustment range of the adjusting sleeve 24 is greater than or equal to the distance between two adjacent pin holes 221.

[0031] Thus, the template support frame with adjustable elevation of this utility model achieves the first type of height adjustment by adjusting the length of the portion of the support rod 22 extending from the top opening of the support tube 21. This is suitable for local fine-tuning. After adjusting the height, the positioning pin 23 is inserted into the insertion hole 211 of the support tube 21 and the corresponding pin hole 221 on the support rod 22, achieving a limiting connection between the support rod 22 and the support tube 21. By rotating the adjusting sleeve 24, the adjusting sleeve 24 moves upward relative to the support rod 22, achieving the second type of height adjustment, which is suitable for precision adjustment. The adjustment accuracy at this point can reach ±1mm. The adjustment height for the second type of height adjustment can be determined according to the thread specifications (such as the thread pitch) on the threaded connection section 222. By combining the two height adjustment methods, the height adjustment range of the template support frame of this utility model is improved. The template support frame with adjustable elevation of this utility model has the advantages of simple operation and ease of use.

[0032] In one specific embodiment of this utility model, there are two positioning pins 23, which are arranged alternately in an upper and lower position, and both positioning pins 23 pass through the support tube 21 and the support rod 22.

[0033] Both positioning pins 23 are positioned near the top opening of the support tube 21, and preferably arranged in a cross shape. Correspondingly, a first through hole is provided on the support tube 21 below the insertion hole 211, and a second through hole is provided on the support rod 22 below the corresponding pin hole 221. When the corresponding pin hole 221 is aligned with the insertion hole 211, the corresponding second through hole can be aligned with the first through hole. Then, one positioning pin 23 can be inserted into the insertion hole 211 and the pin hole 221, and the other positioning pin 23 can be inserted into the first through hole and the second through hole.

[0034] This utility model connects the support rod 22 and the support tube 21 through staggered positioning pins 23, which can improve the connection strength between the support rod 22 and the support tube 21, thereby improving the overall structural strength of the template support frame and ensuring the support strength of the template.

[0035] Furthermore, the distance between the pin hole 221 at the bottom of the support rod 22 and the bottom of the support rod 22 is greater than or equal to the distance between two adjacent pin holes 221. In this way, it can be ensured that when the support rod 22 extends outward to its maximum adjustable length, the bottom of the support rod 22 is still partially inside the support tube 21, thereby improving the structural stability of the support rod 21.

[0036] Furthermore, five pin holes 221 are provided, with a distance of 50mm between any two adjacent pin holes 221. Thus, the pin holes 221 provide height adjustment functions for the template support frame, including adjustments of 50mm, 100mm, 150mm, and 200mm. Based on this, combined with the threaded adjustment of the adjusting sleeve 24, the height adjustment range of the adjusting sleeve 24 is greater than the distance between any two adjacent pin holes, i.e., the height adjustment range of the adjusting sleeve 24 is greater than 50mm. Therefore, the adjustment range of the template support frame of this invention is from 0 to 250mm, with an adjustment accuracy of ±1mm.

[0037] Furthermore, a reading scale is provided on the support rod 22 at the position corresponding to the pin hole 221. Specifically, the reading scale can be marked according to the spacing of the pin holes. When the spacing of the pin holes is designed to be 50mm, a mark of 0 is set at the first pin hole, a mark of 50 is set at the second pin hole, a mark of 100 is set at the third pin hole, a mark of 150 is set at the fourth pin hole, and a mark of 200 is set at the fifth pin hole. In this way, when raising the support rod 22 to adjust the height, the corresponding height value can be easily and conveniently obtained according to the above marks.

[0038] In one specific embodiment of this utility model, a vertically arranged flat portion is formed at the threaded connection section 222, and a scale is provided on the flat portion. The height adjustment value of the sleeve 24 can be easily read and adjusted by the scale.

[0039] Furthermore, the length of the adjusting sleeve 24 is greater than the distance between two adjacent pin holes 221 on the support rod 22. Preferably, the length of the adjusting sleeve 24 and the threaded connection section 222 is set to be twice or more the distance between two adjacent pin holes 221. When the adjustment range of the adjusting sleeve 24 is equal to the distance between two adjacent pin holes 221, it can be ensured that the length of the threaded connection between the adjusting sleeve 24 and the threaded connection section 222 is greater than or equal to the adjustment range, thereby ensuring the structural stability of the adjusting sleeve 24. Additionally, the flat portion extends upward from the bottom of the threaded connection section 222 to the middle of the threaded connection section 222, so that the design of this flat portion does not affect the firmness of the threaded connection.

[0040] Furthermore, such as Figure 3 As shown, a pair of handles 242 are provided on the outer side of the adjusting sleeve 24, which can be easily rotated and adjusted by the handles.

[0041] Furthermore, the adjusting sleeve 24 has a bottom opening and a closed top. The top surface of the adjusting sleeve 24 forms a template support surface.

[0042] In one specific embodiment of this utility model, the support rod 22 and the adjusting sleeve 24 are cylindrical.

[0043] like Figure 1 As shown, the support rod 22 is a tubular structure, such as... Figure 2 As shown, the support rod 22 is a solid rod-shaped structure.

[0044] The construction process of this utility model's adjustable elevation template support frame is described below.

[0045] When setting up formwork, a supporting scaffold or other frame structure providing stable support is installed below the formwork. The formwork support frame of this invention is then connected to the scaffold or frame structure. For example, the support pipe can be connected to the upright pipe on the scaffold or frame structure via a disc buckle. The insertion position of the support rod is then adjusted to achieve localized fine-tuning, adjusting the elevation of the support frame to a precision range of 50mm. The positioning pin is then inserted to fix the support rod. The adjusting sleeve is then rotated to adjust the elevation of the formwork support frame to the correct position. The adjustment accuracy of the adjusting sleeve is ±1mm. After adjustment, the elevation can be measured using a laser rangefinder. The formwork is then placed on the adjusting sleeve. When disassembling the formwork, the adjusting sleeve can be rotated downwards to allow the top of the adjusting sleeve to leave the bottom surface of the formwork. The positioning pin is then pulled out, allowing the support rod to extend into the support pipe, separating the formwork support frame from the formwork. The formwork can then be removed.

[0046] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
