Description

Technical Field

[0001] The utility model relates to the technical field of post-cast strip supports, in particular to a support structure for a concrete construction column of a post-cast strip. Background Technique

[0002] A post-cast strip is a concrete strip left at corresponding positions of the foundation slab, wall, and beam according to design or construction specification requirements to prevent harmful cracks that may occur in a reinforced concrete structure due to uneven self-shrinkage or settlement. The traditional formwork support system for the post-cast strip on the top slab uses independent supports of steel pipe formwork or bowl-coupler formwork, which are retained when the formwork supports on both sides of the structure are demolished, and are demolished after the concrete in the post-cast strip is poured and cured for 28 days. However, the traditional post-cast strip support system has many disadvantages, such as occupying a large amount of formwork and support materials, being extremely easy to damage the support materials, and having a large daily management difficulty, etc., resulting in the traditional support system being unable to meet the requirements of some special scenarios, such as scenarios where the post-cast strip support system needs to be retained for a long time. Therefore, people have adopted the method of constructing temporary concrete support columns to replace the traditional support system, thereby overcoming the defects of the traditional support system.

[0003] In a Chinese utility model patent with the publication number of CN216766770U, a support device for a construction column post-cast strip is disclosed, which includes a first fixing plate and a second fixing plate that are detachably connected. A plurality of first adjustment holes are provided on the first fixing plate, a plurality of third adjustment holes are provided on the second fixing plate, a first support plate is provided at the top of the first fixing plate, a second support plate is provided at the bottom of the second fixing plate, a first adjustment plate is slidably connected to the right side of the first fixing plate, a second adjustment plate is slidably connected to the right side of the second fixing plate, a plurality of second adjustment holes are provided on the first adjustment plate, and a plurality of fourth adjustment holes are provided on the second adjustment plate.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: In the above patent, adjusting the height is very cumbersome by splicing the first fixing plate and the second fixing plate with multiple bolts, making the installation not convenient and the demolition more difficult. Content of the Utility Model

[0005] In order to solve the above problems, the utility model provides a support structure for a concrete construction column of a post-cast strip.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A support structure for a post-cast strip concrete structural column, including a base. On both side walls of the base, there are support plates. On the side walls of the two support plates close to each other, there are fixed plates. Each fixed plate is fixed to the base by screws. On the upper surface of each fixed plate, there are a plurality of adjustment holes for the screws to pass through. On the upper surface of the base, there is a mounting tube. Inside the mounting tube, there is a screw rod rotatably connected to the upper surface of the base. A support block threaded to the screw rod is sleeved on the screw rod. The support block is slidably connected to the inner wall of the mounting tube. On the upper surface of the support block, there is a top plate. A driving component for driving the screw rod to rotate is installed on the mounting tube.

[0008] By adopting the above technical solution, during use, the staff places the base between the structural columns, adjusts the position of the support plate through different adjustment holes, so that the support plate abuts against the structural column according to the distance between the structural columns. Then, the driving component is used to drive the screw rod to rotate. Since the screw rod is threaded to the support block and the support block is slidably connected to the inner wall of the mounting tube, the support block moves upward along the axial direction of the screw rod, so that the top plate supports the post-cast strip upward, eliminating the cumbersome operation of splicing through multiple bolts and facilitating the rapid installation and disassembly of the support structure.

[0009] Further, the driving component includes a rotating rod penetrating through and rotatably connected to the side wall of the mounting tube, a driving bevel gear fixed to one end of the rotating rod close to the screw rod, a driven bevel gear fixedly sleeved on the screw rod and meshing with the driving bevel gear, and a star handle fixed to the other end of the rotating rod away from the driving bevel gear.

[0010] By adopting the above technical solution, when the screw rod needs to be rotated, the staff only needs to rotate the rotating rod and the driving bevel gear through the star handle, so that the driven bevel gear meshing with the driving bevel gear and the screw rod fixed to the driven bevel gear rotate, facilitating the adjustment of the height of the support block and the top plate.

[0011] Further, a limiting component for limiting the rotating rod is installed on the mounting tube. The limiting component includes a ratchet fixedly sleeved on the rotating rod, a rotating shaft rotatably connected to the side wall of the mounting tube, and a pawl fixedly sleeved on the rotating shaft and meshing with the ratchet.

[0012] By adopting the above technical solution, after the height of the support block and the top plate is adjusted, the pawl meshes with the ratchet, playing a limiting role in the rotation of the rotating rod, so that the rotating rod can only rotate in one direction, thus preventing the support block from sliding down and reducing the probability of the support block moving downward due to the automatic rotation of the rotating rod.

[0013] Further, a torsion spring is sleeved on the rotating shaft. One end of the torsion spring is fixed to the side wall of the pawl, and the other end of the torsion spring is fixed to the side wall of the mounting tube.

[0014] By adopting the above technical solution, the torsion spring is arranged so that the pawl remains engaged with the ratchet under the torsion force of the torsion spring, reducing the probability that the pawl disengages from the ratchet and causes the rotating rod to rotate.

[0015] Furthermore, a limiting groove is formed in the inner wall of the installation pipe, and a limiting block slidably connected to the limiting groove is fixed on the side wall of the support block.

[0016] By adopting the above technical solution, the limiting block is slidably connected in the limiting groove, which restricts the moving position of the support block and avoids the situation that the support block disengages from the installation pipe upward, facilitating the normal use of the support mechanism.

[0017] Furthermore, a protective cover for covering the star-shaped handle and the limiting assembly is fixed to the side wall of the installation pipe by screws.

[0018] By adopting the above technical solution, after adjusting the support structure, the staff fixes the protective cover to the side wall of the installation pipe by screws, which plays a protective role for the star-shaped handle and the limiting assembly, reduces the probability of accidentally touching the star-shaped handle and the limiting assembly, and at the same time reduces the probability of damage to the star-shaped handle and the limiting assembly under external forces.

[0019] Furthermore, a reinforcing rod is fixed to the side wall of the support plate, and the end of the reinforcing rod away from the support plate abuts against the upper surface of the base.

[0020] By adopting the above technical solution, the reinforcing rod plays a role in supporting and strengthening the side wall of the support plate, enhancing the stability of the support plate against the structural column.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. In this application, when in use, the staff places the base between the structural columns and adjusts the position of the support plate through different adjustment holes, so that the support plate abuts against the structural column according to the distance between the structural columns. Then, the driving component is used to drive the screw rod to rotate. Since the screw rod is threadedly connected to the support block and the support block is slidably connected to the inner wall of the installation pipe, the support block moves upward along the axial direction of the screw rod, so that the top plate supports the post-cast strip upward, eliminating the cumbersome operation of splicing through multiple bolts and facilitating the quick installation and disassembly of the support structure;

[0023] 2. In this application, when it is necessary to rotate the screw rod, the staff only needs to rotate the rotating rod and the driving bevel gear through the star-shaped handle, so that the driven bevel gear engaged with the driving bevel gear and the screw rod fixed to the driven bevel gear rotate, facilitating the adjustment of the height of the support block and the top plate;

[0024] 3. In this application, after adjusting the heights of the support block and the top plate, the pawl engages with the ratchet wheel, restricting the rotation of the rotating rod so that the rotating rod can only rotate in one direction, preventing the support block from sliding down and reducing the probability of the support block moving downward due to the automatic rotation of the rotating rod.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0031] As Figures 1-4 shown, an embodiment of the present application discloses a support structure for a post-cast strip concrete construction column, including a base 1, a support plate 2, a fixing plate 3, a mounting tube 4, a screw 5, a support block 6, a top plate 7, and a drive assembly 8.

[0032] The base 1 is of a cuboid structure and is used to carry the device. The support plate 2 is of a rectangular plate structure, and there are two support plates 2 which are respectively arranged on the side walls on both sides of the base 1. The fixing plate 3 is of a rectangular plate structure, and there are two fixing plates 3 which are respectively fixed on the side walls of the two support plates 2 on the side close to each other. Each fixing plate 3 is fixed to the base 1 by screws, and a plurality of adjusting holes 31 for the screws to pass through are vertically formed on the upper surface of each fixing plate 3. The installation pipe 4 is of a vertically arranged rectangular tubular structure and is fixed on the upper surface of the base 1. The screw rod 5 is of a vertically arranged rod structure, and the screw rod 5 is arranged in the installation pipe 4 and is rotatably connected to the upper surface of the base 1. The support block 6 is of a cuboid structure, the support block 6 is sleeved on the screw rod 5 and is threadedly connected to the screw rod 5, and the support block 6 is slidably connected to the inner wall of the installation pipe 4. The top plate 7 is of a rectangular plate structure and is fixed on the upper surface of the support block 6.

[0033] The driving assembly 8 is installed on the installation pipe 4 and is used to drive the screw rod 5 to rotate. The driving assembly 8 includes a rotating rod 81, a driving bevel gear 82, a driven bevel gear 83 and a star-shaped handle 84. The rotating rod 81 is of a horizontally arranged round rod structure, and the rotating rod 81 is arranged through the side wall of the installation pipe 4 and is rotatably connected. The driving bevel gear 82 is fixed to one end of the rotating rod 81 close to the screw rod 5, and the axis of the driving bevel gear 82 coincides with the axis of the rotating rod 81. The driven bevel gear 83 is fixedly sleeved on the screw rod 5, the driven bevel gear 83 meshes with the driving bevel gear 82, and the axis of the driven bevel gear 83 coincides with the axis of the screw rod 5. The star-shaped handle 84 is fixed to the end of the rotating rod 81 far from the driving bevel gear 82, and the axis of the star-shaped handle 84 coincides with the axis of the rotating rod 81.

[0034] During use, the staff places the base 1 between the construction columns, adjusts the position of the support plate 2 through different adjusting holes 31, so that the support plate 2 abuts against the construction column according to the distance between the construction columns, and then rotates the rotating rod 81 and the driving bevel gear 82 through the star-shaped handle 84, so that the driven bevel gear 83 meshing with the driving bevel gear 82 and the screw rod 5 fixed to the driven bevel gear 83 rotate. Since the screw rod 5 is threadedly connected to the support block 6 and the support block 6 is slidably connected to the inner wall of the installation pipe 4, the support block 6 moves upward along the axial direction of the screw rod 5, so that the top plate 7 supports the post-cast strip upward, eliminating the cumbersome operation of splicing through multiple bolts and facilitating the rapid installation and disassembly of the support structure.

[0035] In order to reduce the probability of the automatic rotation of the rotating rod 81, a limiting component 9 is installed on the installation pipe 4 for limiting the rotating rod 81. The limiting component 9 includes a ratchet wheel 91, a rotating shaft 92 and a pawl 93. The ratchet wheel 91 is fixedly sleeved on the rotating rod 81, and the axis of the ratchet wheel 91 coincides with the axis of the rotating rod 81. The rotating shaft 92 is a horizontally arranged round rod-shaped structure, and the rotating shaft 92 is rotatably connected to the side wall of the installation pipe 4. The pawl 93 is fixedly sleeved on the rotating shaft 92, and the pawl 93 meshes with the ratchet wheel 91. After the heights of the support block 6 and the top plate 7 are adjusted, the pawl 93 meshes with the ratchet wheel 91, which plays a role in restricting the rotation of the rotating rod 81, so that the rotating rod 81 can only rotate to one side, thereby preventing the support block 6 from sliding down, and thus reducing the probability of the downward movement of the support block 6 caused by the automatic rotation of the rotating rod 81.

[0036] In order to reduce the probability of the pawl 93 disengaging from the meshing state with the ratchet wheel 91, a torsion spring 10 is sleeved on the rotating shaft 92. One end of the torsion spring 10 is fixed to the side wall of the pawl 93, and the other end of the torsion spring 10 is fixed to the side wall of the installation pipe 4. The setting of the torsion spring 10 enables the pawl 93 to maintain the meshing state with the ratchet wheel 91 under the action of the torsion force of the torsion spring 10, thereby reducing the probability of the rotation of the rotating rod 81 caused by the pawl 93 disengaging from the meshing state with the ratchet wheel 91.

[0037] In order to prevent the support block 6 from disengaging upward from the installation pipe 4, a limiting groove 41 is opened on the inner wall of the installation pipe 4, and a limiting block 11 slidably connected to the limiting groove 41 is fixed on the side wall of the support block 6. The limiting block 11 is slidably connected in the limiting groove 41, which plays a role in restricting the moving position of the support block 6, thereby preventing the support block 6 from disengaging upward from the installation pipe 4, which is beneficial to the normal use of the support mechanism.

[0038] In order to protect the star-shaped handle 84 and the limiting component 9, a protective cover 12 for covering the star-shaped handle 84 and the limiting component 9 is fixed to the side wall of the installation pipe 4 by screws. After the support structure is adjusted, the staff fixes the protective cover 12 to the side wall of the installation pipe 4 by screws, which plays a protective role for the star-shaped handle 84 and the limiting component 9, reduces the probability of accidentally touching the star-shaped handle 84 and the limiting component 9, and at the same time reduces the probability of damage to the star-shaped handle 84 and the limiting component 9 under the action of external forces.

[0039] In order to enhance the stability of the support plate 2, a reinforcing rod 13 is fixed to the side wall of the support plate 2. The end of the reinforcing rod 13 away from the support plate 2 abuts against the upper surface of the base 1. The reinforcing rod 13 plays a role in supporting and strengthening the side wall of the support plate 2, thereby enhancing the stability of the support plate 2 against the construction column.

[0040] The working principle of a post-cast strip concrete construction column support structure in this embodiment is as follows:

[0041] During use, the staff place the base 1 between the construction columns, and adjust the position of the support plate 2 through different adjustment holes 31, so that the support plate 2 abuts against the construction columns according to the distance between the construction columns. Then, rotate the rotating rod 81 and the driving bevel gear 82 through the star-shaped handle 84, so that the driven bevel gear 83 meshing with the driving bevel gear 82 and the screw rod 5 fixed to the driven bevel gear 83 rotate. Since the screw rod 5 is threadedly connected to the support block 6 and the support block 6 is slidably connected to the inner wall of the mounting pipe 4, the support block 6 moves upward along the axial direction of the screw rod 5, so that the top plate 7 supports the post-cast strip upward, eliminating the cumbersome operation of splicing through multiple bolts and facilitating the rapid installation and disassembly of the support structure.

[0042] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
