Detailed Description
The structure of the cable trough prefabricated by adopting the template system is shown in fig. 3 and comprises a side wall 61, a vertical wall 62 and a protective wall 63, wherein the protective wall 63 has different heights according to the requirement of a route. As can also be seen in fig. 3, the present formwork system prefabricates cable troughs in a downwardly opening manner.
As can be seen from fig. 1 and 2, the formwork system disclosed in this embodiment includes a bottom frame 1, a bottom mold 2, side molds 3, an inner mold 4, and an end mold 5.
The underframe 1 is a mounting platform of the whole template system, the bottom die 2, the side die 3 and the inner die 4 are all mounted on the underframe 1, the end dies 5 cover two ends of the bottom die 2, the side die 3 and the inner die 4 and are detachably connected with the bottom die 2, the side die 3 and the inner die 4 through bolts.
As can be seen in fig. 1, 2 and 5, the bottom mold 2 includes a side wall bottom mold 21, a vertical wall bottom mold 22 and a protection wall bottom mold 23, which are installed at corresponding positions on the base frame 1 according to the design positions of the side walls, the vertical walls and the protection walls of the cable trough.
In order to prevent slurry leakage during concrete pouring, rubber strips XJT are respectively arranged on two sides of the side wall bottom die 21, the vertical wall bottom die 22 and the protective wall bottom die 23.
Because the protecting wall of cable duct has different height demands, so the mounting height of protecting wall die block needs to be adjustable to the prefabrication of the matching not high protecting wall, so this embodiment is installed protecting wall die block 23 on chassis 1 through screw assembly 13, and the accessible rotates the mounting height that the screw comes the adjustment protecting wall die block like this.
As can be seen from fig. 1 and 2, the two side molds 3 are a whole mold plate, are respectively disposed on the outer sides of the side wall bottom mold 21 and the protective wall bottom mold 23, and are respectively used for molding the outer wall of the side wall and the outer wall of the protective wall, the lower ends of the two side molds are respectively hinged to the bottom frame 1, and meanwhile, spiral support rods 31 which are obliquely arranged are respectively disposed between the outer sides of the two side molds 3 and the bottom frame 1 to serve as telescopic supports.
The spiral stay bar 31 can not only support the side die 3, but also realize the die erection and the die stripping of the side die by adjusting the length of the spiral stay bar.
Since the prefabricated member has two relatively independent grooves, two groove surfaces are prefabricated by two independent sets of inner molds 4, one set being located between the side wall 61 and the vertical wall 62, and the other set being located between the vertical wall 62 and the protective wall 63.
As can be seen from fig. 1, 2 and 6, a row of hinge seats 11 is respectively disposed on the chassis 1 corresponding to the middle position of the top surface of each inner mold 4.

As can be seen from fig. 1, 2, 4 and 6, each inner mold 4 further includes a vertical and a demolding assembly, the vertical and demolding assembly includes a rotating shaft 42, and a cam plate 421, a lever 422 and a locking ear plate 423 connected thereto, two sides of the cam plate 421 are respectively connected with a connecting rod 43, and in this embodiment, a mode of clamping and hinging two connecting rods by a pair of cam plates is adopted.
The rotating shaft 42 is arranged along the length direction of the inner die plates 41, two ends of the rotating shaft are rotatably arranged in rotating shaft limiting holes on the bottom frame 1, the middle of the cam plate 421 is connected to the rotating shaft and rotates along with the rotating shaft, the other ends of the connecting rods 43 on two sides of the cam plate are respectively hinged with the inner die plates 41 on the corresponding sides, when the die is erected, the rotating shaft 42 is rotated, the connecting rods 43 on two sides simultaneously open the two inner die plates 41 together, and when the die is demolded, the rotating shaft rotates reversely to enable the connecting rods on two sides to simultaneously draw the two inner die plates.
The number of the cam plates on the rotating shaft is set according to needs, but at least two cam plates need to be arranged.
The two pull rods are respectively connected to two ends of the rotating shaft, and the rotating shaft is rotated through the pull rods to be easier and more labor-saving. The locking lug plates are fixed on two sides of the rotating shaft corresponding to the underframe, and after the rotating shaft enables the inner die template to stand in place, the locking lug plates can be fixed with the underframe through bolts to limit rotation of the rotating shaft, so that the inner die template is fixed, and the locking lug plates also play a role in limiting longitudinal movement of the rotating shaft.
Fig. 1 shows the clamping state of the present clamping system.
And after the die is closed, hoisting the concrete into a reinforcement cage to pour the concrete, wherein the demolding sequence after the concrete pouring and curing is finished is as follows:
removing connecting bolts among the end die 5, the side die 3, the inner die 4 and the bottom die 2, and lifting off the end die 3;
the spiral support rods 31 on the two sides are respectively rotated to shorten the length of the spiral support rods, so that the two side dies 3 respectively rotate outwards around the hinged parts at the lower ends of the two side dies to open the die;
and removing the bolts between the locking lug plates and the underframe on the rotating shaft 42 to loosen the locking lug plates 423, rotating the rotating shaft 42, and pulling the connecting rods 43 to enable the two inner die templates 41 of each group of inner dies to rotate around the hinged positions at the tops of the two inner die templates for inward shrinkage and die removal.
And finally, lifting the poured prefabricated member and moving the prefabricated member to a storage area.
When the cable grooves with different protection wall heights are prefabricated, only the screw rod connected with the protection wall bottom die and the underframe needs to be rotated, and the working face height of the protection wall bottom die 23 is adjusted to a proper position.
The bottom die, the side die and the inner die are all installed on the bottom frame, the end die can be detachably covered on the bottom die, the side die and the inner die are all connected with the bottom frame in a hinged mode, the telescopic support hinged between the outer side of the side die and the bottom frame and the vertical and demolding assembly hinged between the inner die and the bottom frame play roles in standing, supporting and demolding. The hinged connection mode is simple to operate, so that the side die and the inner die can be conveniently and quickly erected and demoulded in a mechanical rotating mode.
Each internal mold comprises a left internal mold template and a right internal mold template, so that each internal mold has only one joint, the number of the template blocks of the whole template system is small, and the demolding operation is simple and efficient.
All exposed surfaces of the prefabricated member are molded through the template, the surface concrete molding effect is good, and the subsequent work of modifying the concrete surface can be completely omitted.
