Description
Technical Field
[0001] This utility model relates to the field of support structures, specifically a support structure for basement square column formwork. Background Technology
[0002] Square column formwork is a formwork system used in building construction for pouring concrete square columns. It typically consists of multiple components, including the formwork itself, reinforcements, and fasteners, to ensure that the formwork maintains its shape and stability during concrete pouring. Square column formwork is suitable for various building projects, especially for the construction of basements in high-rise buildings and large-span structures. This method can improve construction efficiency and quality, and is suitable for projects with short construction cycles and tight schedules. However, with the increasing use of square column formwork, problems such as formwork leakage and bulging are prone to occur during pouring after the formwork is installed. Therefore, a support structure needs to be designed to solve the problems that arise during use.
[0003] An existing basement square column formwork support structure involves fixing back ribs to one side of four sets of formwork, assembling the four sets of formwork into a square column model, and then placing the four sets of square column buckles crosswise to provide initial limiting support for the formwork. Multiple grooves are opened at both ends of the square column buckles. After the square column buckles are placed crosswise, fixing pins are fitted into the grooves, and the fixing pins are fixed in the grooves by hammering. This allows the square column buckles to be fixedly installed on the side of the formwork, thus achieving an effective support effect.
[0004] However, for the existing basement square column formwork support structure, the fixing pins are fixed in the trench by hammering, and then the square column is fixed in the side of the formwork. After the square column is cast, the fixing pins need to be removed one by one by hammering because they are fixed in the trench. This seriously affects the demolding efficiency and will affect the construction process. Moreover, the hammering can easily cause the fixing pins to fall to the ground, which may hit the ground or construction workers, thus affecting the normal construction of the project. Utility Model Content
[0005] Based on this, the purpose of this utility model is to provide a basement square column formwork support structure to solve the technical problem of poor performance of existing basement square column formwork support structures.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a basement square column formwork support structure, comprising a short plate, a long plate provided on one side of the short plate, a back rib fixedly installed on one side of the short plate, a groove provided inside the back rib, a first steel pipe provided on one side of the back rib, mounting grooves provided at both ends of the first steel pipe, a second mounting block and a limiting block sequentially provided on one side of the first steel pipe, a sliding rod sleeved inside the second mounting block, a slider provided on the sliding rod, a back rib fixedly installed on one side of the long plate, a groove provided inside the back rib, a second steel pipe provided on one side of the back rib, and a first mounting block fixedly installed on one side of the back rib fixedly installed on one side of the short plate.
[0007] By adopting the above technical solution, the problem of poor performance of existing basement square column formwork support structures is solved. A back rib is provided, with a groove inside. A first mounting block is fixedly installed on one side of the back rib. Multiple sets of second mounting blocks and limiting blocks are sequentially installed at the bottom of the first steel pipe. A sliding rod is movably installed between the first, second, and limiting blocks. When formwork support is required, short and long plates are spliced together to form a square column model. Two sets of first and second steel pipes are then staggered and installed at the bottom of the groove. The fixing rod is then hammered into the grooves at both ends of the first and second steel pipes, thus fixing the first and second steel pipes to the side of the square column where the short and long plates are spliced, providing support for the short and long plates. The effect is achieved by rotating the slide rod to a horizontal angle and pushing it into the first mounting block. Rotating the slide rod further causes one end to contact the end of the limiting block downwards, limiting its movement and preventing the first and second steel pipes from sliding into the groove during use. When the square column needs to be demolded after casting, one end of the slide rod is rotated to a horizontal position, and then the slide rod and one end are moved to one side of the limiting block to release the limitation on the first steel pipe. Then, by hammering, the first and second steel pipes are slid upwards, allowing them to slide into the groove and loosen, making it easy to remove the fixing rod. This improves the efficiency of the workers and avoids engineering accidents during demolding.
[0008] The present invention is further configured such that multiple sets of grooves are opened at both ends of the first steel pipe and the second steel pipe, and the lengths of the first steel pipe and the second steel pipe are both greater than the length of the long plate.
[0009] Preferably, multiple sets of grooves are opened at both ends of the first steel pipe and the second steel pipe to facilitate the installation of the fixing rod. The lengths of the first steel pipe and the second steel pipe are both greater than the length of the long plate, so that the first steel pipe and the second steel pipe can achieve the desired effect.
[0010] The present invention is further provided that a fixing rod is fixedly installed in the grooves opened at both ends of the first steel pipe and the second steel pipe, and the fixing rod is configured as a cone shape.
[0011] Preferably, a fixing rod is fixedly installed in the grooves opened at both ends of the first steel pipe and the second steel pipe. The fixing rod is set in the shape of a cone, so that the first steel pipe and the second steel pipe can be fixedly installed on the side of the short plate and the long plate through the fixing rod, thereby playing a supporting and limiting role for the short plate and the long plate.
[0012] The present invention is further configured such that the short plate and the long plate have the same thickness, and the short plate has square grooves of equal length and width on both sides, and the width of the square grooves is set to half the thickness of the short plate or the long plate.
[0013] Preferably, by having the same thickness for the short plate and the long plate, and by providing square grooves of equal length and width on both sides of the short plate, with the width of the square grooves set to half the thickness of the short plate or the long plate, the short plate and the long plate can ensure the strength of the short plate while achieving the condition of preventing leakage, and avoid reducing the effectiveness of the short plate by opening the grooves too large.
[0014] The present invention is further configured such that the width of the second steel pipe is smaller than the width of the first steel pipe, and the second steel pipe is fitted into the mounting grooves opened at both ends of the first steel pipe.
[0015] Preferably, by setting the width of the second steel pipe to be smaller than the width of the first steel pipe, and fitting the second steel pipe into the mounting grooves opened at both ends of the first steel pipe, the first steel pipe and the second steel pipe can be installed on the sides of the short plate and the long plate, thereby achieving the desired effect.
[0016] The present invention is further configured such that both the first mounting block and the second mounting block have through holes inside, and the diameter of the through holes is the same as the diameter of the slide rod.
[0017] Preferably, by providing through holes inside both the first and second mounting blocks, with the diameter of the through holes being the same as the diameter of the slide rod, the slide rod can be installed between the first and second mounting blocks, preventing collisions between the slide rod and the first and second mounting blocks, thus affecting the normal use of the device.
[0018] The present invention is further configured such that the limiting block is L-shaped and is tangent to the through holes opened inside the first mounting block and the second mounting block.
[0019] Preferably, by setting the limiting block to an L-shape, the sliding rod can be limited. The limiting block is tangent to the through holes opened inside the first mounting block and the second mounting block, so that the sliding rod can be slidably mounted on one side of the limiting block.
[0020] The present invention is further configured such that the slide rod is an L-shaped round rod, and one end of the slide rod is disposed on one side of the limiting block.
[0021] Preferably, by setting the slide rod as an L-shaped round rod, with one end of the slide rod positioned on one side of the limiting block, the limiting block can act as a barrier against the L-shaped side of the slide rod, thereby limiting the slide rod.
[0022] The present invention is further configured such that the slider is disposed between the second mounting block and the limiting block, the length of the slider is the same as that of the first steel pipe, and the first mounting block is fixedly installed at the bottom of the groove.
[0023] Preferably, by placing the slider between the second mounting block and the limiting block, the slide rod can be restricted between the second mounting block and the limiting block, preventing the slide rod from being pulled out from one side of the limiting block, thus affecting the normal use of the device. The length of the slide rod is the same as that of the first steel pipe to prevent the slide rod from being too long and unable to be fitted into the first mounting block. The first mounting block is fixedly installed at the bottom of the slot so that the first steel pipe and the second steel pipe can achieve the desired effect.
[0024] In summary, the present invention has the following main advantages:
[0025] This utility model solves the problem of poor performance of existing basement square column formwork support structures by incorporating a short plate, a long plate, a back rib, a groove, a first steel pipe, an installation groove, a second steel pipe, a fixing rod, a first installation block, a second installation block, a limiting block, a sliding rod, and a slider. The back rib has a groove, and a first installation block is fixedly installed on one side of the back rib. Multiple sets of second installation blocks and limiting blocks are sequentially arranged at the bottom of the first steel pipe. A sliding rod is movably installed between the first installation blocks, second installation blocks, and limiting blocks. When formwork support is needed, the short plate and long plate are spliced together to form a square column model. Two sets of first and second steel pipes are then alternately installed at the bottom of the groove. The fixing rod is then hammered into the grooves at both ends of the first and second steel pipes, thus fixing the first and second steel pipes to the short plate. The side of the square column, where the long and short plates are spliced, provides support for the short and long plates. The sliding rod is then rotated to a horizontal angle and pushed into the first mounting block. Rotating the sliding rod further downwards so that one end contacts the side of the limiting block, limits its movement and prevents the first and second steel pipes from sliding into the groove during use. When the square column needs to be demolded after casting, one end of the sliding rod is rotated to a horizontal position, and then the sliding rod and one end are moved to the side of the limiting block to release the limitation on the first steel pipe. Then, by hammering, the first and second steel pipes are slid upwards into the groove, loosening them and allowing the fixing rod to be easily removed. This improves worker efficiency and prevents accidents during demolding.
[0026] This utility model incorporates a short plate with square grooves of equal length and width on both sides. When mold assembly is required, fitting one end of the long plate into the square groove increases the contact area between the short and long plates, allowing them to fit tightly together. During pouring, this prevents concrete leakage from the side of the formwork, enhancing the device's practicality. Furthermore, the inclusion of a sliding rod with a slider positioned between the second mounting block and the limiting block provides a limiting effect, preventing the sliding rod from being removed from the bottom of the first steel pipe and ensuring the device's proper functioning.

[0046] In practical operation, this utility model requires the use of a short plate 1 and a long plate 2 for formwork support. The short plate 1 and the long plate 2 are spliced together to form a square column model. A back rib 3 is provided on one side of both the short plate 1 and the long plate 2. A slot 4 is opened in the back rib 3. A first mounting block 8 is fixedly installed on one side of the slot 4. In addition, multiple sets of second mounting blocks 9 and limiting blocks 10 are sequentially arranged at the bottom of the first steel pipe 5. A sliding rod 11 is movably installed between the first mounting block 8, the second mounting block 9 and the limiting block 10. After the short plate 1 and the long plate 2 are spliced together, the two sets of first steel pipes 5 and second steel pipes 6 are staggered and installed in the slot. At the bottom of opening 4, the fixing rod 7 is fixed in the grooves at both ends of the first steel pipe 5 and the second steel pipe 6 by hammering, so that the first steel pipe 5 and the second steel pipe 6 are fixedly installed on the side of the square column where the short plate 1 and the long plate 2 are spliced, thus providing support for the short plate 1 and the long plate 2. Then, the sliding rod 11 is rotated to a horizontal angle and pushed into the through hole opened in the first mounting block 8. Rotating the sliding rod 11 so that one end of the sliding rod 11 contacts one end of the limiting block 10 downwards, provides a limiting effect on the movement of the sliding rod 11, and prevents the first steel pipe 5 and the second steel pipe 6 from sliding into the groove 4 during use. When demolding is required after the column casting is completed, one end of the sliding rod 11 is rotated to a horizontal position. Then, the sliding rod 11 and one end of the sliding rod 11 are moved to one side of the limiting block 10 to release the limiting effect of the sliding rod 11 on the first steel pipe 5. Then, the first steel pipe 5 and the second steel pipe 6 are slid upward by hammering, so that the first steel pipe 5 and the second steel pipe 6 can slide into the groove 4, making the first steel pipe 5 and the second steel pipe 6 loose, so that the fixing rod 7 can be easily removed. This improves the work efficiency of the workers and avoids engineering accidents during the demolding process. At the same time, the same length and width of the positive openings are opened on both sides of the short plate 1. The square groove, when spliced in the mold, increases the contact area between the short plate 1 and the long plate 2 by fitting one end of the long plate 2 into the square groove, allowing the short plate 1 and the long plate 2 to fit tightly together. During pouring, it can prevent concrete from leaking from the side of the formwork, enhancing the practicality of the device. Furthermore, by setting a sliding rod 11, and a slider 111 on the sliding rod 11, which is located between the second mounting block 9 and the limiting block 10, the sliding rod 11 can be limited, preventing it from being removed from the bottom of the first steel pipe 5, thus ensuring the normal use of the device.
