[0003] The Chinese patent with the publication number CN219886948U discloses a basement post-cast strip waterproof structure, which drives two threaded rods to rotate synchronously through the multi-stage mechanical transmission of "handle - main bevel gear - from bevel gear - sprocket - transmission chain", and further drives the connecting seat, connecting column and top movable plate to lift, realizing height adjustment; meanwhile, a folding sleeve is arranged outside the adjusting assembly to prevent dust and impurities from affecting the operation of the transmission components.

[0004] The above-mentioned patent has the following problems:

[0005] Although the design improves the lifting stability of the movable plate through the double-threaded rod structure, meets the basic height adjustment requirement, but in actual application, the double-threaded rod synchronous lifting structure cannot completely guarantee that no height difference occurs during the lifting process, and cannot completely guarantee that no height difference occurs during the lifting process, so as to cause the inclination of the movable plate or the problem that the movable plate cannot be lifted and lowered directly. In view of this, the basement post-cast strip waterproof structure based on steel sheet net and micro-expansion concrete is proposed. UTILITY MODEL CONTENTS

[0006] The utility model aims at providing the basement post-cast strip waterproof structure based on steel sheet net and micro-expansion concrete to solve the problems in the background art.

[0007] Therefore, the utility model provides the basement post-cast strip waterproof structure based on steel sheet net and micro-expansion concrete, which comprises a box body, two sliding holes are formed in the upper side of the box body, two supporting columns are slidably installed in the sliding holes, movable plates are fixedly installed at the top ends of the two supporting columns, a jacking assembly is fixedly installed at the bottom ends of the two supporting columns, the jacking assembly comprises two movable blocks, the two movable blocks are fixedly installed at the bottom ends of the two supporting columns correspondingly, the lower sides of the two movable blocks are arc-shaped, two sliding grooves are formed in the inner bottom wall of the box body, two limit blocks are slidably installed in the sliding grooves, guide plates are fixedly installed on the upper sides of the two limit blocks, the surfaces of the two guide plates are inclined surfaces and are attached to the lower sides of the movable plates, and a driving unit is rotatably installed on one side of the box body.

[0008] In the technical solution, when the driving unit works, two guide plates are driven to move synchronously in opposite directions or in the same direction in the horizontal direction. Since the upper surface of the guide plate is an inclined surface and the lower side of the movable block is an arc surface, when the guide plate moves horizontally, the inclined surface of the guide plate generates a vertical component force on the movable block. When the two guide plates move in opposite directions, they press the movable block, forcing the support column and the movable plate to rise together. Conversely, they fall. The limiting block slides in the sliding groove to ensure that the guide plate can only move horizontally. A single driving source is used to act on two movable blocks through two inclined guide plates, which fundamentally ensures the absolute synchronization of the two support points in lifting, completely avoids the problems of asynchronization, jamming or inclination of the movable plate in the traditional double-wire rod structure, ensures the stability of the lifting process and the levelness of the movable plate, has high mechanical efficiency, is not easy to damage, is convenient to maintain, and the inclined surface mechanism can amplify the horizontal driving force into a vertical lifting force, and has good carrying capacity.

[0010] In the technical solution, when the bidirectional screw rod is rotated, the two adjusting blocks move synchronously in opposite directions or in the same direction due to the opposite directions of the threads. The movement of the adjusting blocks is transmitted to the expansion block through the expansion arms. The expansion arms, the adjusting blocks and the expansion block are all hinged. When the two adjusting blocks move close to each other, they push the two expansion blocks away from each other, thereby driving the two guide plates fixed thereon to move in opposite directions, achieving lifting, and vice versa.

[0015] In the above technical solution, further, the surface of the positioning plug rod is fixedly installed with a limiting ring, one end of the shell cover is fixedly installed with a shell cover, and the limiting ring and the shell cover are fixedly installed with the same reset spring.

[0016] In the technical solution, in a natural state, the elastic force of the reset spring pushes the limiting ring and the positioning plug rod, so that they have the tendency of being inserted into the plug-in slot. When it is required to unlock the height adjustment, the positioning plug rod needs to be pulled out against the spring force, and after adjustment, the spring force automatically pushes the positioning plug rod into the nearest plug-in slot to complete the locking, so that the operation is simplified, the locking operation is automatically completed after the adjustment is completed, and the forgetting of locking is prevented.

[0017] In the above technical solution, further, the upper side of the movable plate is fixedly installed with a waterproof roll material.

[0018] In the technical solution, the waterproof roll material is a key material which directly contacts with the basement post-cast strip structure and plays a waterproof role, when the movable plate is jacked to the appropriate height, the waterproof roll material thereon is closely attached to the structure surface below the post-cast strip, and a waterproof barrier is formed.

[0019] In the above technical solution, further, one end of the positioning plug rod is fixedly installed with a pulling block.

Since the upper surfaces of the guide plates 7 are inclined surfaces and the lower sides of the movable blocks 6 are arc-shaped surfaces, when the guide plates 7 move horizontally, the inclined surfaces of the guide plates 7 generate a vertical component force on the movable blocks 6. When the two guide plates 7 move away from each other, they press the movable blocks 6, forcing the support columns 5 and the movable plates 2 to rise together, and vice versa.
