step three: after the whole frame is installed, a buffer mechanism is installed inside the loading cavity 3, and the bearing plate 23 is clamped with the loading cavity 3 through a third clamping buckle 22 and a clamping groove 26 at the bottom; a spring 24 in the clamping groove 26 pushes a push plate 25 to abut against the bottom of the third buckle 22, and a telescopic end above the elastic telescopic column 19 is inserted in the concave hole 20;
step four: after the whole frame and the buffer mechanism are installed, the fastening bolt 7 is screwed, the distance between the decoration mechanism 6 and the bottom frame 1 is adjusted, before the concrete 2 is filled in the frame, the whole frame is placed into a mold of a prefabricated part, and then the concrete 2 is filled in the bottom frame 1, the top frame 9 and the space between the bottom frame 1 and the decoration mechanism 6; the concrete 2 enters the whole frame from top to bottom through the through holes 17, and covers the bottom frame 1, the top frame 9 and the cushion blocks 10.
When the prefabricated member is used, the bottom frames 1 with proper number are selected according to the size requirement of an actual prefabricated member, and the bottom frames 1 are spliced and installed from bottom to top. When the bottom frames 1 are mounted with each other, the top frame 9 is firstly clamped and mounted on the upper portion of each bottom frame 1 through the first sliding chute 8 and the first buckle 18. When the underframe 1 of top and the underframe 1 of below were installed, the installation of second buckle and the second spout 12 joint on cushion 10 upper portion was passed through to the bottom of top underframe 1. And then make the installation dismantlement that a plurality of underframe 1 can be free, and the installation dismantlement is simple swift, can adapt to different work demands, and accommodation is extensive.
Underframe 1 can be according to the size and the kind of prefab adjust the quantity of underframe 1 upper portion cushion 10 before the installation, can dismantle underframe 1 upper portion both sides and the cushion 10 at both ends middle part, saves the cost under the circumstances of guaranteeing the prefab and reaching the demand. And screwing the screw, removing the screw from the screw hole 16, and finally pulling the cushion block 10 out of the inserting hole 15.
After the installation of underframe 1 and top frame 9, according to the actual demand that the prefab outside was decorated, at whole frame outside installation decoration mechanism 6 all around.

A plurality of end plates 31 and the bottom plate 29 are spliced to form a complete decoration mechanism 6, and the decoration mechanism 6 is not easy to fall off in use. Make the prefab preparation accomplish the back, decorate mechanism 6 and can decorate externally for whole prefab is more pleasing to the eye, and the prefab has higher decorative after the installation in the building, need not decorate again in the outside of prefab, has saved the cost of decorating. And the size and the appearance of the decoration mechanism 6 can be manufactured according to actual requirements, the adaptability is good, and the decoration mechanism can be widely used.
After the whole frame is installed, a buffer mechanism can be installed inside the loading cavity 3. The bearing plate 23 is clamped with the loading cavity 3 through the third clamping buckle 22 and the clamping groove 26 at the bottom, so that the bearing plate 23 can be simply and quickly mounted and dismounted in the loading cavity 3. The spring 24 in the clamping groove 26 can push the push plate 25 to abut against the bottom of the third clamping buckle 22, so that the bearing plate 23 is not prone to shaking and falling off in the loading cavity 3. After the bearing plate 23 is installed inside the loading cavity 3, the telescopic end above the elastic telescopic column 19 is inserted into the concave hole 20. The elastic telescopic column 19 can limit and fix the bearing plate 23 and can play a role in buffering in the loading cavity 3. When the bearing plate 23 needs to be taken out, a screwdriver is inserted into the through hole 21 and presses the telescopic end of the elastic telescopic column 19 downwards until the telescopic end on the upper part is separated from the concave hole 20, and the bearing plate 23 is pushed to move out of the clamping groove 26.
After the whole frame and the buffer mechanism are installed, the fastening bolt 7 is screwed, the distance between the decoration mechanism 6 and the bottom frame 1 is adjusted, and then the size of the whole prefabricated part is controlled. Before the inside of the frame is filled with concrete, the whole frame is put into a mould of a prefabricated member, and then the bottom frame 1, the top frame 9 and the space between the bottom frame 1 and the decoration mechanism 6 are filled with concrete 2. The concrete 2 can fully enter the whole frame through the through holes 17 from top to bottom, the bottom frame 1, the top frame 9 and the cushion blocks 10 can be covered, and the concrete 2 can also enter the loading cavity 3. After the whole concrete prefabricated part is subjected to external force in use, the bottom frame 1, the top frame 9, the cushion block 10 and the internal buffer mechanism made of glass fiber reinforced plastic can play a good protection role, have higher toughness and buffer force, are not easy to damage in use and have good safety performance.
