Description

Technical Field

[0001] The invention relates to the technical field of prefabricated part formwork, in particular to a prefabricated part steel formwork that can be quickly disassembled. Background Art

[0002] Precast concrete parts are prefabricated in a way that they are cast in advance using the mold cavity of the template and can be directly assembled and used after being transported to the construction site. Traditional cast-in-place concrete requires on-site molding, on-site pouring and on-site maintenance. Precast concrete parts are widely used in construction, transportation, water conservancy and other industries. Precast parts are widely used due to their flexibility and other advantages. Some concrete pipes with larger diameters are difficult to form by centrifugal molding due to their larger diameters. The traditional method of using templates for casting is still used. The structure of the current precast steel template is not convenient for rotating anti-sticking work. Concrete is very easy to adhere to the template and is not easy to demold. Usually, multiple templates are required to be bolted together. At the same time, it is not convenient to cast and position the concrete steel cage. The steel cage has a large deviation after forming. The method of using radial positioning ribs to fit the template will cause the steel bars to be exposed after forming, which is easy to rust. During the casting process, the aggregate is easy to settle under the impact of adding materials, affecting the uniformity of the aggregate of the precast part. Summary of the invention

The problem is solved by rotating. During the rotation process, as the concrete solidifies, the rapidly rotating rotating outer mold 2 and the rotating inner mold 3 will be separated from the concrete mold, and the concrete mold will be attached to the lower mold base 101, ensuring flexibility in use and more efficient disassembly and assembly. The rotation method is convenient for disassembly and assembly, and there is no need to assemble and splice multiple templates or to disassemble cumbersome bolts. At the same time, the outer mold 201 and the inner mold 301 of the structure are simple and convenient to install, and the structure is more reasonable, especially for the molding of large prefabricated pipe fittings.

[0039] In the embodiment of the present disclosure, the positioning member 4 includes: a positioning plug plate 401 and an inclined extrusion block 402, the positioning plug plate 401 is slidably plugged into the outer mold 201; the inner side of the positioning plug plate 401 is flush with the outer mold 201; the inclined extrusion block 402 is fixedly installed on the positioning plug plate 401; the inclined extrusion block 402 is a slope structure; the two ends of the positioning plug plate 401 are respectively connected to the other end of the reset tension spring 204 on the same side; the positioning plug plate 401 is used to position the steel cage; the spiral mixing member 5 includes: a spiral plug plate 501 and a movable connecting plate 502, the spiral plug plate 501 is a spiral arc structure; the spiral plug plate 501 is slidably plugged into the inner mold 301 The end of the spiral plug plate 501 is flush with the outer side of the inner mold 301; a movable connecting plate 502 is fixedly installed on the spiral plug plate 501; the spiral plug plate 501 is used to extend out of the inner mold 301 to mix concrete; the spiral mixing element 5 also includes: a mixing slider 503 and a reset slide column 504, a mixing slider 503 is fixedly installed on the movable connecting plate 502, and the mixing slider 503 is an inclined structure; there are two reset slide columns 504, and the two reset slide columns 504 are respectively fixedly installed inside the inner mold 301; the movable connecting plate 502 is slidably installed on the two reset slide columns 504; the two reset slide columns 504 are respectively sleeved with springs, By adopting the spiral mixing element 5 and utilizing its spiral structure, the concrete can be mixed and stirred during the rotation of the inner mold 301, and the mixing of the concrete aggregate particles can be effectively promoted. At the same time, the structure can use the positioning element 4 to position the steel cage in real time during the rotation of the outer mold 201, thereby ensuring the installation accuracy of the steel cage. In particular, when the concrete is not poured, the problem of concentricity deviation between the steel cage and the outer mold 201 caused by the impact of concrete pouring can be prevented. At the same time, the structure does not need to set positioning ribs on the steel cage, thus avoiding the situation in which the steel cage is radially provided with positioning ribs to fit the template, resulting in the steel cage after forming being deformed. The exposed reinforcement is prone to rust; after pouring concrete into the cavity between the outer mold 201 and the inner mold 301, segmented pouring can be adopted.

By squeezing the control member 7, a circle of positioning plug plates 401 can be controlled to move inward to realize the positioning of the steel cage. The outer side of the steel cage can be clamped inward at the same time. After the concrete is poured, the positioning plug plate 401 can be retracted, and the filled concrete can be used to fill the positioning steel cage to ensure the installation accuracy of the steel cage; a concrete pouring port is provided on the upper mold 602.

[0041] The working principle of this embodiment is as follows: First, a crane is used to hang and control the hanging holes on the outer mold 201 and the inner mold 301, and the inner mold 301 and the outer mold 201 are hung and inserted into the inner rotation groove 1011 and the outer rotation groove 1012 respectively. A steel cage is placed in the outer mold 201, and concrete is filled in the inner rotation groove 1011 and the outer rotation groove 1012. The four hanging ears on the upper mold 602 are hung by a crane, and the upper mold 602 is hung on the lifting control column 601. The bottom of the upper mold 602 is rotated and installed in the grooves at the top of the outer mold 201 and the inner mold 301. Before pouring concrete, the lifting control cylinder 703 drives the lifting mounting frame 702 to descend, and the positioning extrusion ring 704 can be used to squeeze a circle of inclined extrusion blocks 402, and the positioning plug plate 401 can be controlled to move inward to realize the positioning of the steel cage. The driving motor 103 drives the driving gear 104 to rotate, and the meshing teeth 202 of the outer mold and the meshing teeth 302 of the inner mold are engaged, and the outer mold 201 and the inner mold 301 are controlled to rotate quickly, which does not affect the concrete molding. At the same time, the concrete will not adhere to the outer mold 201 and the inner mold 301, and the pouring is completed. After the molding is completed, when the positioning extrusion ring 704 moves up and resets, the extrusion of the inclined extrusion block 402 can be released, and the positioning plug plate 401 can be reset under the pull of the reset tension spring 204. The end of the positioning plug plate 401 will be flush with the inner side of the outer mold 201 to ensure smooth molding. At the same time, when the lifting mounting frame 702 descends, the mixing extrusion ring 705 can be used to extrude the mixing slider 503, driving the spiral plug plate 501 to extend, and the rotation of the inner mold 301 can drive the spiral plug plate 501 to rotate at the same time. The spiral structure is used to mix concrete. After the pouring is completed, the lifting mounting frame 702 can be lifted and lowered. The lowering mounting frame 702 rises, and at this time the mixing extrusion ring 705 releases the extrusion mixing slider 503, and the spiral plug plate 501 can be reset by being pressed down by the springs respectively sleeved on the reset slide column 504, and the end of the spiral plug plate 501 retracts and is flush with the inner mold 301, ensuring a smooth molding surface and subsequent smooth demoulding. Part of the concrete can be poured again to fill it densely, and the vibration generated by the vibration motor 303 can play a role in removing bubbles. After the concrete is solidified, the outer mold 201 and the hanging holes on the inner mold 301 are demoulded by using a crane to control the demoulding.
