Detailed ways

Implementation: 1: As shown in the figure, a mobile adjustable support formwork frame for a trench construction column, including a bracket, the bracket includes a base plate, and the base plate is composed of a left base plate 15 and a right base plate 11, and the right base plate 15 is inserted into The left base plate 11 can be telescopically adjusted, and the sides of the left base plate 15 and the right base plate 11 are provided with corresponding through holes 19 and mounting holes 20. The through holes 19 and the mounting holes 20 are arranged at equal intervals. Fastening screws 21 are provided at the mounting holes 20 , and the relative positions of the left base plate 15 and the right base plate 11 are fixed by the fastening screws 21 .

The left base plate 15 and the right base plate 11 are respectively provided with a vertical rod 9, the vertical rod 9 top is axially provided with an internally threaded hole 23, and the internally threaded hole 23 places are equipped with a threaded rod 14, and the upper end of the threaded rod 14 is provided with a handle 4; The connection between the upper end of the rod 14 and the handle 4 is provided with a recessed annular groove 13. The annular groove 13 is provided with a sleeve 12 that can rotate independently. The outer arc surface of the casing 12 is hinged with an upper connecting rod 2, the other end of the upper connecting rod 2 is hinged with a mounting plate 5, and the lower end of the vertical rod 9 and the mounting plate 5 are hinged with a lower connecting rod 7. 9. A telescopic connecting rod 6 is arranged transversely and symmetrically in the middle part, and the other end of the telescopic connecting rod 6 is fixedly connected with the mounting plate 5 . The above-mentioned installation plate 5 is two symmetrically arranged, and the described upper connecting rod 2, the lower connecting rod 7 and the telescopic connecting rod 6 are also arranged symmetrically.

The ends on both sides of the left base plate 22 and the right base plate 11 are provided with positionally symmetrical rollers 18, the rollers 18 are provided with a wheel frame 17, and the wheel frame 17 is installed on the sides of the left base plate 22 and the right base plate 11 by pin shafts 15 and can be Rotate, be provided with pin hole 25 below pin shaft 15, be provided with through hole with pin hole 25 position correspondences on wheel frame 17, be provided with pin 16 at through hole and pin hole 25 place, pass wheel frame 17 by pin 16 Being fixed on the side surfaces of the left base plate 22 and the right base plate 11 can make the wheel frame 17 vertically arranged with the ground, and in this case the formwork frame can be moved as a whole.

The quantity of above-mentioned pole 9 is at least two, and a plurality of poles 9 can be installed on the upper end surface of left base plate 22 and right base plate 11, in order to guarantee the vertical stability of pole 9, between pole 9 and left base plate 22 and right base plate A plurality of reinforcement plates 26 may also be provided between the upper end surfaces of the base plate 11 .

There are two sets of formwork telescopic mechanisms in this embodiment, and more telescopic mechanisms can be provided on the base plate according to actual applications to meet the needs of construction. The lengths of the left base plate and the right base plate can also be appropriately adjusted according to site requirements.

Embodiment 2: The structure of this embodiment is the same as the substrate of Embodiment 1, the difference is that a bearing 24 is provided at the connection between the upper end of the threaded rod 14 and the handle 4, and the sleeve 12 is installed outside the bearing 24 for use. The threaded rod 14 and the bushing 12 realize relative rotation.

When in use, the formwork frame is placed in the pre-excavated trench, and the position between the left base plate and the right base plate is adjusted according to the distance between adjacent structural columns, which is the distance between two adjacent mounting plates and the distance between adjacent structural columns. The spacing is equal, and the length of the substrate is determined and fastened by fastening screws. Then install the same type of formwork used for the construction column to the mounting plate. In order to ensure that the formwork is installed stably, multiple mounting holes at different positions can be pre-drilled on the mounting plate, so that formworks of different sizes can be installed to adapt to construction columns of different sizes. After the template is installed, pull out the pins at the four wheel brackets on the base plate, rotate the wheel bracket to lift the wheel bracket and the rollers, when the wheel bracket is placed above the pin hole, insert the pin into the pin hole, and pass The pin prevents the wheel frame from falling, and the bottom surface of the base plate at this time just falls on the bottom surface of the sprocket wheel groove, so that the stability of the entire formwork frame can be maintained. Rotate the handle to make the threaded rod move downwards, and the casing set at the upper end of the threaded rod moves downwards with the threaded rod. Since the upper connecting rod is movably connected between the casing and the mounting plate, the lower end of the vertical rod is movably connected with the mounting plate. There is a lower connecting rod, and the length of the upper connecting rod and the lower connecting rod is the same, and the upper connecting rod and the lower connecting rod protrude outwards, and simultaneously drive the mounting plate to move to the outside. In order to ensure that the mounting plate can move horizontally, a horizontal telescopic rod is also provided at the middle part between the mounting plate and the vertical rod. When the formwork on the installation plate pushes against the steel bars of the structural columns on both sides, stop turning the handle, and then the structural columns can be poured with cement.

Due to the long groove distance and the large number of structural columns, multiple formwork frames can be used at the same time in practical applications. After a part of the structural columns are poured, turn the handle to move the mounting plate and formwork inwards to separate them from the structural columns. Then put down the wheel frame and rollers on the base plate, fix the roller frame with pins and then move to the vicinity of the next structural column to be poured, and repeat the above steps to proceed to the next step.
