Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a frame column formwork installation structure and installation method. Background Technology

[0002] Currently, frame columns are the main vertical support structures that bear the loads from beams and slabs in frame structures and transfer the loads to the foundation. Frame column formwork is the formwork used to cast frame columns.

[0003] In the construction of prefabricated building frame columns, traditional formwork is typically made on-site, using a combination of wooden boards, square timber, and pipe supports. When workers use these traditional formworks to pour concrete for the frame columns, they first create wooden boards according to the column dimensions, then install these boards on the outside of the column. Next, square timber is vertically positioned on the outside of the wooden boards. Finally, ropes are used to horizontally fix the pipe supports to the side of the square timber furthest from the column. This completes the fixing of the building frame column formwork. Traditional wooden formwork is prone to wear and tear, has a complex structure, and has low assembly efficiency before pouring. Installation and dismantling waste a significant amount of time and manpower.

[0004] A Chinese patent (publication number: CN109853946A) proposes a column formwork structure and its installation method, including corner formwork, flat formwork, and fixing components. The corner formwork is vertically set at the corner of the frame column, and the flat formwork is vertically set between two adjacent corner formworks. The fixing components are set on the side of the corner formwork and flat formwork away from the frame column and fix the corner formwork and flat formwork. The fixing components include corner fixing brackets and locking components. The corner fixing brackets are set on the side of the corner formwork away from the frame column and abut against the corner formwork. The locking components are evenly distributed from top to bottom between two adjacent corner fixing brackets and fix the flat formwork and corner fixing brackets. This achieves the effects of simplifying the formwork structure, facilitating disassembly and assembly, and saving time and manpower.

[0005] A Chinese patent (publication number: CN214696848U) discloses a column formwork installation structure, which includes a column formwork mechanism, vertical ribs, and multiple sets of column clamp mechanisms. The column formwork mechanism includes four column formworks and four column formwork corners, which are spliced ​​together to form a rectangular column. The column formwork corners are located between adjacent column formworks and are fixedly connected to the two column formworks. The vertical ribs are fixedly installed on the outer wall of the column formworks. The column clamp mechanisms are sleeved on the column formwork mechanism to fix the column formwork mechanism. Each set of column clamp mechanisms includes a vertical clamp, two rotating clamps, and two positioning components. The two rotating clamps are located on the vertical clamp and connected to the vertical clamp to form a rectangular frame. The ends of the two rotating clamps away from the vertical clamp are fixedly connected. The two positioning components are located at the connection between the vertical clamp and the two rotating clamps. This application has the effect of improving the defect of column formwork fasteners being prone to loosening and causing column formwork deformation.

[0006] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: Locking the column hoops installed on the formwork is cumbersome, reducing formwork installation efficiency and hindering later formwork disassembly. Furthermore, when pouring concrete for taller square columns, it is inconvenient for construction workers to lock multiple column hoops at equal intervals on the formwork during the formwork erection process. If the distance between two adjacent column hoops is too large during pouring, the formwork will be pushed outwards under the weight of the concrete, causing deformation and affecting the pouring quality. Therefore, we propose a frame column formwork installation structure and method to solve these problems. Summary of the Invention

[0007] This invention provides a frame column formwork installation structure and method, solving the technical problems of cumbersome operation, reduced formwork installation efficiency, and inconvenience for later disassembly of the formwork when locking the column hoops installed on the formwork during the formwork body erection process for square columns higher than 3 meters. Furthermore, it addresses the issue that during the pouring of concrete, if the distance between two adjacent column hoops is too large, the formwork is pushed outward under the weight of the concrete, causing deformation and affecting the pouring quality.

[0008] To solve the above technical problems, a frame column template installation structure provided by the present invention includes a template body arranged in a cube shape, and a plurality of column hoop mechanisms distributed along the length direction of the template body for fixing the template body. The template body is spliced by two first templates and two second templates. The column hoop mechanism includes a first hoop body and a second hoop body arranged in a "C" shape. First connecting plates are symmetrically arranged on the first hoop body, a rotating shaft is rotatably installed on the first connecting plates, and a connecting seat is installed on the rotating shaft. Second connecting plates are symmetrically arranged on the second hoop body, and the connecting seat can be flipped towards the second connecting plates and sleeve the second connecting plates inside. A sliding cavity for the second connecting plates to slide in the direction of approaching or departing from the first connecting plates is arranged on the connecting seat, a push block for driving the second connecting plates to slide is slidably connected inside the sliding cavity, and a driving component for driving the push block to slide;

[0009] The driving component includes a threaded sleeve rotatably connected to the side wall of the connecting seat. A threaded rod is threadedly connected inside the threaded sleeve. One end of the threaded rod is connected to the push block, a transmission worm gear fixedly sleeved on the threaded sleeve and located outside the connecting seat. A bearing plate is installed on the side wall of the connecting seat, and a shaft seat is installed on the bearing plate. A transmission worm shaft rotatably connected and meshed with the transmission worm gear is installed on the shaft seat.

[0010] Preferably, vertical ribs are arranged at intervals on the outer side walls of the first template and the second template. Mold grooves are provided on the left and right side walls of the first template, and mold corners adapted to the mold grooves are provided on the side walls of the second template. After the template body is spliced, the mold corners are clamped inside the mold grooves.

[0011] Preferably, first support ridges and second support ridges are arranged on the inner walls of the first hoop body and the second hoop body. The first support ridges are movably inserted between two adjacent vertical ribs on the outer surface of the first template, and the second support ridges are movably inserted between two adjacent vertical ribs on the outer surface of the second template.

[0012] Preferably, a spring seat is fixedly connected to the bearing plate, a spring pin is slidably inserted into the spring seat, and a plurality of pin holes for inserting the spring pin are provided on the transmission worm gear.

[0013] Preferably, a telescopic guide rod is installed on the side wall of the push block, and the other end of the telescopic guide rod is connected to the inner wall of the connecting seat.

[0014] Preferably, an installation shell is installed on the outer wall of the first template, a rotating column is rotatably installed inside the installation shell, and a smooth rod is also installed inside the installation shell. The same number of sliders as the column hoop mechanism are slidably installed on the smooth rod. The sliders are connected to the outer walls of the first hoop and the second hoop. A transmission rod is connected to the other side of the slider. A spiral transmission groove is opened on the rotating column. The end of the transmission rod away from the slider is inserted into the spiral transmission groove. A drive worm gear is installed on the outer wall of the bottom end of the rotating column. A drive worm is rotatably installed on the side wall of the installation shell. The drive worm gear and the drive worm are meshed together.

[0015] Preferably, a ratchet is fixedly installed on the bottom outer wall of the rotating column, a pawl is rotatably installed on the inner bottom wall of the mounting housing, the pawl engages with the ratchet, a support spring is installed on the side wall of the pawl, the other end of the support spring is connected to the inner wall of the mounting housing, and a push rod is slidably installed on the front end face of the mounting housing, with one end of the push rod extending into the interior of the mounting housing connected to the side wall of the pawl.

[0016] A method for installing frame column formwork includes the following steps:

[0017] S1. First, mark the column axis and edge lines on the floor, determine the elevation, and level the column base;

[0018] S2. Support the formwork body;

[0019] S3. Push the push rod to engage the pawl and rotate. The pawl separates from the ratchet, and the rotating drive worm drives the meshing drive worm wheel to rotate. The drive worm wheel drives the rotating column to rotate. Through the spiral transmission groove set on the rotating column, multiple transmission rods can be driven to move with varying pitch. The transmission rods drive the slider to move. The slider drives the first hoop and the second hoop to adjust their positions. This ensures that the spacing between two adjacent column hoop mechanisms is the same, avoiding excessive spacing between two adjacent column hoop mechanisms. Under the action of the concrete gravity, the formwork body is pushed outward, which causes the formwork body to deform and affects the pouring quality.

[0020] S4. Multiple column hoop mechanisms are added to fix the template body. Since the first hoop and the second hoop are spliced ​​and sleeved on the template body, the connecting seat on the first connecting plate is rotated to sleeve the second connecting plate inside. At this time, the column hoop is in an unlocked state. After all the first hoop and the second hoop are pre-installed, the transmission worm gear is rotated to drive the transmission worm wheel to rotate, thereby realizing the rotation of the threaded sleeve. The threaded rod moves horizontally along the inner wall of the threaded sleeve. The threaded rod can push the push block to move. The push block pushes the second connecting plate to slide towards the first connecting plate, thereby realizing the second hoop to close towards the first hoop. This makes the column hoop mechanism hug the template body, thereby fixing the template body.

[0021] S5. Place the steel cage;

[0022] S6. Concrete pouring.

[0023] Compared with related technologies, the frame column formwork installation structure and installation method provided by the present invention have the following beneficial effects:

[0024] In this invention, by setting a first template, a second template, vertical ribs, template corners, template grooves, and column hoop mechanism, the template can be assembled and fixed, achieving the effects of simplifying the template structure, facilitating disassembly and assembly, and saving time and manpower.

[0025] In this invention, by pushing the push rod to abut against the pawl and causing it to rotate, the pawl separates from the ratchet. The rotating drive worm then drives the meshing drive worm wheel to rotate, which in turn drives the rotating column to rotate. The spiral transmission groove on the rotating column can drive multiple transmission rods to move with varying pitch. The transmission rods drive the slider to move, and the slider drives the first hoop and the second hoop to adjust their positions. This ensures that the spacing between two adjacent column hoop mechanisms is the same, preventing the spacing between two adjacent column hoop mechanisms from being too large. This would cause the formwork body to be pushed outward under the weight of the concrete, resulting in deformation of the formwork body and affecting the pouring quality. Attached Figure Description

The threaded rod (610) can push the push block (611) to move. The push block (611) pushes the second connecting plate (608) to slide towards the first connecting plate (605), thereby enabling the second hoop (602) to close towards the first hoop (601), so that the column hoop mechanism (6) is tightly held on the template body, thereby fixing the template body. S5. Place the steel cage; S6. Concrete pouring.
