Description

Technical Field

[0001] The utility model belongs to the technical field of casting strip formwork, and in particular relates to a concrete post-casting strip formwork. Background Art

[0002] Concrete post-cast joints refer to the concrete parts that cannot be completed in the same pouring process during the pouring of concrete components due to construction conditions, technical requirements or design requirements. These parts are usually poured after the initial pouring is completed and the concrete hardens to a certain strength. The post-cast joint formwork can effectively prevent the concrete from overflowing during pouring, ensuring the neatness of the pouring and the stability of the structure. Before the concrete reaches the design strength, the formwork provides the necessary support to prevent deformation or collapse.

[0003] Patent CN215484636U discloses a reinforced concrete post-cast strip formwork, including a formwork and a supporting device, wherein the formwork is supported by the supporting device at the bottom of the post-cast strip, wherein: an anti-deviation system is provided between the support column of the supporting device and the formwork, and the anti-deviation system includes: a first anti-deviation component, which is arranged at the top of the support column, and the first anti-deviation component is provided with four first anti-deviation parts; a second anti-deviation component, which is arranged on the formwork, and the second anti-deviation component is provided with second anti-deviation parts corresponding to the four first anti-deviation parts one by one; wherein, by cooperating the first anti-deviation part with the corresponding second anti-deviation part, the formwork is prevented from shifting relative to the post-cast strip in the length direction and the width direction, but the formwork is not only not convenient to disassemble quickly and conveniently and has poor load-bearing support effect, but also the support column of the formwork cannot be conveniently adjusted in length, which is not convenient for flexible adjustment when supporting different construction sites.

[0007] Preferably, a spring is sleeved on the outside of the locking rod, and the spring is located between the limiting ring and the retaining plate.

[0008] Preferably, a handle is fixedly connected to the outside of the locking rod, and the handle is made of stainless steel.

[0009] Preferably, the bottom of the mounting block is fixedly connected to two correspondingly distributed fixing plates, the interiors of the two fixing plates are both threadedly connected to limiting screws, and the limiting screws abut against the sliding grooves.

[0010] Preferably, the lifting mechanism includes an adjustment hole, which is opened on the outside of the support column, and a through hole is opened inside the sleeve. A fixing bolt is inserted into the through hole, and the fixing bolt passes through the adjustment hole. The external thread of the fixing bolt is connected to a fixing nut.

[0011] Preferably, the number of the adjustment holes is six, and the six adjustment holes are evenly distributed outside the support column.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] By pulling the two locking rods backward, and then inserting the locking block fixed on the top of the support column into the locking groove, and then loosening the two locking rods, the locking rod is pushed forward by the elasticity of the spring, so that the locking rod passes through the mounting seat and is inserted into the locking block to complete the fixation. When the template needs to be supported, first rotate the two limiting screws. Since the limiting screws and the fixed plate are threadedly connected, they will move upward when rotating, and then slide in the sliding groove to push its support rod upward. At this time, the support rod rotates around the movable axis, and then drives the load-bearing seat hinged on the outside of the support rod to contact the bottom of the template, thereby supporting it, making the template's load-bearing effect better and more stable.

[0014] By placing the template at the bottom of the construction position and then pulling the support column upward, the support column slides inside the sleeve, and then drives the top template to move upward at the same time. When it moves to the appropriate position, the fixing bolt is inserted into the through hole and passes through the adjustment hole to limit the height of the template. Then the fixing nut is threaded onto the outside of the fixing bolt to prevent it from falling off and make it more stable. Through the multiple adjustment holes, it can be conveniently and flexibly adjusted to a variety of heights to meet construction requirements. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom of the two support rods 405 is provided with sliding grooves 409, and the outside of the positioning rod 412 is sleeved with a spring 413, and the spring 413 is located between the limiting ring 414 and the retaining plate 411. The outside of the positioning rod 412 is fixedly connected with a handle 415, and the handle 415 is made of stainless steel. The bottom of the mounting block 403 is fixedly connected to two corresponding fixed plates 407, and the inside of the two fixed plates 407 are threadedly connected to the limiting screw 408, and the limiting screw 408 abuts against the sliding groove 409.

[0024] When the template 1 needs to be installed quickly, the two locking rods 412 are first pulled backward, and then the locking block 402 fixed on the top of the support column 2 is inserted into the locking groove 410, and then the two locking rods 412 are released. At this time, the locking rod 412 is pushed forward by the elasticity of the spring 413, so that the locking rod 412 passes through the mounting seat 401 and is inserted into the locking block 402, so that the fixation is completed. When the template 1 needs to be supported, the two limiting screws 408 are first rotated. Since the limiting screw 408 is threadedly connected to the fixing plate 407, it will move upward when rotating, and then slide in the sliding groove 409, pushing its support rod 405 upward.

At this time, the locking rod 412 is pushed forward by the elasticity of the spring 413, so that the locking rod 412 passes through the mounting seat 401 and is inserted into the locking block 402, so that the fixation is completed. When the template 1 needs to be supported, first rotate the two limiting screws 408. Since the limiting screw 408 is threadedly connected to the fixing plate 407, it will move upward when rotating, and then slide in the sliding groove 409, pushing its support rod 405 upward.

When flexible support is needed at different construction positions, first place the template 1 at the bottom of the construction position, and then pull the support column 2 upward. At this time, the support column 2 slides inside the sleeve 3, and then drives the top template 1 to move upward at the same time. When it moves to the appropriate position, the fixing bolt 502 is inserted into the through hole 503 and passes through the adjustment hole 501, thereby limiting the height of the template 1, and then the fixing nut 504 is threadedly connected to the outside of the fixing bolt 502 to prevent it from falling off and to be more stable. The multiple adjustment holes 501 can be conveniently and flexibly adjusted to various heights to meet construction requirements.
