[0032] Example 1

[0033] This embodiment provides, for example Figures 1-6The detachable demolding tool shown includes a main rod 1. A pair of symmetrical armhole beams 3 are fixedly installed at the head end of the main rod 1. A demolding assembly 4 is fixedly installed on the armhole beams 3. The main rod 1 serves as the main body of the demolding tool. The head end of the main rod 1 is used to install the demolding assembly 4. The armhole beams 3 are additionally welded to the main rod 1. The armhole beams 3 serve as the support structure for the demolding assembly 4, so that the demolding assembly 4 can be better integrated with the main rod 1. This provides additional welding points and effectively improves the durability and reliability of the demolding tool.

[0034] An auxiliary rod 2 is provided at the lower end of the main rod 1. The auxiliary rod 2 serves as a length extension structure for the main rod 1. When the template is high, the construction workers can add the auxiliary rod 2 to lengthen the overall demolding tool. One end of the auxiliary rod 2 is fitted with a connecting cylinder 5, which is fixedly connected to the tail end of the main rod 1.

[0035] A locking structure 6 is set on the auxiliary rod 2, and the auxiliary rod 2 is designed as a telescopic rod structure. The extension, retraction and locking of the auxiliary rod 2 are controlled by the locking structure 6.

[0036] Furthermore, such as Figure 1 As shown, the haunch beam 3 is made of L-shaped steel bars. The vertical part of the haunch beam 3 is in the same direction as the main rod 1, which makes it easy to weld to the main rod 1. The horizontal part of the haunch beam 3 is perpendicular to the main rod 1. The demolding assembly 4 is welded to the horizontal part of the haunch beam 3.

[0037] Furthermore, the demolding assembly 4 includes a rocker arm 41 and a top cone 42. One end of the rocker arm 41 is flat and is vertically fixed to one of the armhole beams 3. The top cone 42 is fixedly set on the other armhole beam 3. The top cone 42 is a columnar rod with a conical tip. The sharp tip makes it easier for operators to remove the square timber. The flat end makes it easier for the rocker arm 41 to be inserted into the gap of the template, effectively improving the efficiency of the demolding operation.

[0038] Furthermore, the lower end of the main rod 1 is provided with a connecting thread 7, and the connecting cylinder 5 is provided with an installation thread 8 that matches the connecting thread. By using a threaded connection to install the main rod 1 and the auxiliary rod 2, the connection relationship is made tighter and more reliable. During operation, the structure of the demolding component is more reliable and stable. After the auxiliary rod 2 is used up, the operator can also disassemble the auxiliary rod 2 more quickly.

[0039] Furthermore, such as Figure 2 and Figure 3 As shown, the auxiliary rod 2 includes an outer cylinder 21 and an inner rod 22. A pair of sliding rods 211 are welded on the outer cylinder 21. The two sliding rods 211 are symmetrically installed on the inner wall of the outer cylinder 21. The sliding rods 211 serve as the support structure for the inner rod 22.

[0040] Correspondingly, a groove 221 matching the slide rod 211 is provided on the inner rod 22. The slide rod 211 and the groove 221 are slidably connected. The arrangement of the slide rod 211 and the groove 221 makes the extension and retraction of the inner rod 22 smoother and the structure more reliable.

[0041] Multiple limiting grooves 222 are equidistantly provided at the top of the inner rod 22. The limiting grooves 222 are arranged along the length of the inner rod 22. The limiting grooves 222 are linked with the locking structure 6. The locking structure 6 controls the pushing in and pulling out of the inner rod 22 through the limiting grooves 222. The flat end of the limiting groove 222 is on the side close to the connecting cylinder 5. When the operator holds the inner rod 22 and swings it, the locking structure 6 cooperates with the limiting groove 222 to achieve self-locking and prevent the outer cylinder 21 from coming out.

[0042] The outer cylinder 21 has a mounting hole 212, which is used to install the locking structure 6. The locking structure 6 is installed on the inner wall of the outer cylinder 21 through the mounting hole 212.

[0043] Furthermore, such as Figure 5 and Figure 6 As shown, the latching structure 6 includes a circular button 61, with a groove 611 formed on the button 61, and the button 61 is engaged with the mounting hole 212 through the groove 611.

[0044] A vertical adjusting block 62 is welded to the lower end of the button 61. The adjusting block 62 has a waist hole 63, which faces the length direction of the inner rod 22.

[0045] It also includes a limiting rod 64 located at the lower end of the mounting hole 212. The tail end of the limiting rod 64 is hinged to the outer cylinder 21, and the head end of the limiting rod 64 passes through the waist hole 63 and is fixedly provided with a limiting tooth 65 that matches the limiting groove 222. A return spring 66 is provided between the head end of the limiting rod 64 and the outer cylinder 21.

[0046] In a static state, the limiting tooth 65 of the limiting rod 64 is inserted into the plane end of the limiting groove 222, that is, the height of the head end of the limiting rod 64 is lower than the height of the tail end. The push button 61 drives the adjusting block 62 to move from the tail end of the limiting rod 64 along the length direction of the outer cylinder 21, causing the head end of the limiting rod 64 to move up and down. The reset spring 66 always exerts a downward force on the limiting rod 64 to reset the limiting rod 64.

[0047] When in use: with the top of the main rod 1 as the lever fulcrum, the top cone 42 can be used to remove the square timber, and then the pry bar 41 can be inserted into the gap of the formwork to pry the main rod 1 and remove the formwork; for the removal of the formwork of the top slab and beam with a high floor height, the main rod 1 can be connected to the connecting cylinder 5 on the auxiliary rod 5 through the connecting thread to increase the overall operating length of the formwork removal tool to remove the formwork with a higher height.

[0048] Due to the uncertainty of the site conditions, without affecting the structural strength of the main body, the auxiliary rod 2 is designed as a telescopic rod structure. When a more suitable length is needed, the button 61 can be pushed forward to raise the head of the limiting rod 64, so that the limiting rod 64 leaves the limiting groove 222 of the inner rod 22. At this time, it can be moved to the required position. After releasing the button 61, the limiting rod 64 will return to the limiting groove 222 under the force of the return spring 66. If it does not directly return to the limiting groove 222, the inner rod 22 can be pulled back and forth slightly.

[0049] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
