Description

Technical Field

[0001] The utility model relates to the technical field of PC board production, and particularly relates to a novel PC laminated board mold. Background Technique

[0002] The PC laminated board, also known as the prestressed concrete laminated board, is a structural form that combines the advantages of precast floor slabs and cast-in-place floor slabs. The PC laminated board uses a precast concrete thin slab as the bottom permanent formwork, and a cast-in-place concrete composite layer is poured on the upper part. The two parts of concrete are stressed integrally to form an assembled integral composite floor slab. This structural form makes full use of the convenience of precast components and the strength advantages of cast-in-place concrete.

[0003] In the production process of PC laminated boards, they are mainly classified into two categories. The first category is to add rubber plugs through U-shaped grooves, and the second category is two layers up and down. The fixing methods include fixing with magnetic boxes and punching holes on the die table with bolts.

[0004] For the first category of adding rubber plugs through U-shaped grooves, the manual labor intensity is very high, the efficiency is low, and it is not conducive to production line production.

[0005] For the second category of two layers up and down, the production efficiency is high, but punching holes on the die table with bolts causes great damage to the die table. Opening holes on the die table causes substantial damage to the die table, thereby increasing the production cost. During the production process, the mold is formed by four laminated boards, and it is difficult to ensure the perpendicularity between the four laminated boards, resulting in low forming efficiency of the PC laminated board.

A clamping groove 21 is formed on one side of the bottom surface of the magnetic box structure 2, and a lower surrounding edge structure 3 is adsorbed on the magnetic box structure 2 through the clamping groove 21. The lower surrounding edge structure 3 includes a lower surrounding bottom plate 31, and a clamping plate 37 is fixedly connected to one side surface of the lower surrounding bottom plate 31. The thickness of the lower surrounding bottom plate 31 is the same as that of the clamping plate 37, and the thickness of the lower surrounding bottom plate 31 and the clamping plate 37 is the same as the height of the clamping groove 21. The clamping plate 37 can extend into the clamping groove 21, and the clamping groove 21 of the magnetic box structure 2 adsorbs and fixes the clamping plate 37. A positioning hole 38 is formed on the surface of the clamping plate 37, and a setting hole 22 is formed on the top surface of the magnetic box structure 2. When the clamping plate 37 is positioned and connected to the clamping groove 21, the setting hole 22 is directly above the positioning hole 38, and the same positioning bolt 25 is arranged in the setting hole 22 and the positioning hole 38. The positioning bolt 25 is threadedly connected to the setting hole 22 and the positioning hole 38. Support plates 32 are fixedly connected to both sides of each lower surrounding bottom plate 31. The two support plates 32 are arranged along the vertical direction and are symmetrically arranged with respect to the central plane of the lower surrounding bottom plate 31. A lower surrounding contact plate 33 is fixedly connected to one side of the top surface of the lower surrounding bottom plate 31 away from the clamping plate 37. The two sides of the lower surrounding contact plate 33 are connected to the support plates 32. The support plate 32 and the lower surrounding contact plate 33 are perpendicular to each other, and the support plate 32 and the lower surrounding contact plate 33 have the same height. Lower surrounding magnetic sheets 34 are arranged on both sides of the top surface of the lower surrounding contact plate 33, and the top surfaces of the lower surrounding magnetic sheets 34 on both sides of the top surface have opposite magnetic polarities. A lower surrounding positioning ring 35 and a fixing nut 36 are fixedly connected to the top surface of the lower surrounding bottom plate 31. The lower surrounding positioning ring 35 and the fixing nut 36 have the same height, and the height is less than the height of the lower surrounding contact plate 33.

[0036] The top surface of the lower peripheral edge structure 3 can be superimposed with an upper peripheral edge structure 4, and the upper peripheral edge structure 4 includes a superimposed cylinder 41.

The exposed surface of the second upper peripheral magnetic piece 44 can be mutually adsorbed with the lower peripheral magnetic piece 34 of the lower peripheral edge structure 3, and the two magnetic pieces positionally connect the lower peripheral edge structure 3 and the upper peripheral edge structure 4. The bottom surface of the superimposed cylinder 41 is fixedly connected with a positioning pin 46, and the shape of the fixing pin is adapted to the shape of the lower peripheral positioning ring 35 on the top surface of the lower peripheral bottom plate 31. When the lower peripheral edge structure 3 and the upper peripheral edge structure 4 are snap-fitted and positioned, the bottom end of the positioning pin 46 can extend into the lower peripheral positioning ring 35 for snap-fitting. The top surface of the superimposed cylinder 41 is fixedly connected with an upper peripheral positioning ring 45, the upper peripheral positioning ring 45 is located directly above the positioning pin 46, and the shape of the upper peripheral positioning ring 45 is the same as that of the lower peripheral positioning ring 35. The upper and lower top surfaces of the superimposed cylinder 41 are provided with a setting groove 47. When the upper peripheral edge structure 4 and the lower peripheral edge structure 3 are superimposed, the setting groove 47 is located directly above the fixing nut 36. A fixing bolt 5 is arranged in the setting groove 47, the bottom end of the fixing bolt 5 is threadedly connected with the fixing nut 36, and the top end of the fixing bolt 5 is press-fixed to the top surface of the superimposed cylinder 41.

[0037] The top surface of the upper peripheral edge structure 4 can be superimposed with other upper peripheral edge structures 4.

The positioning pin 46 above extends into the upper peripheral positioning ring 45 below for snap-fitting and positioning. The setting holes 22 of multiple upper peripheral edge structures 4 are located on the same vertical straight line and coincide. Different heights of fixing bolts 5 are used. The bottom end of the fixing bolt 5 is threadedly connected with the fixing nut 36 of the lowermost lower peripheral edge structure 3, and the top end of the fixing bolt 5 contacts and presses and snap-fits with the top surface of the uppermost superimposed cylinder 41. By superimposing the upper peripheral edge structure 4 on the lower peripheral edge structure 3, the thickness of one side of the mold is increased.

[0038] On one side of the magnetic box structure 2 away from the setting groove 47, a mounting magnetic sheet 24 is provided. The magnetic box structure 2 is detachably provided with an infrared structure 6 and a reflection structure 7 through the mounting magnetic sheet 24. The infrared structure 6 includes a first mounting plate 61. On one side of the first mounting plate 61, a first magnetic sheet 62 is provided. The exposed surface of the first magnetic sheet 62 is adsorbed to the exposed surface of the mounting magnetic sheet 24. On the side of the first mounting plate 61 away from the first magnetic sheet 62, an infrared lamp 63 is fixedly connected. The reflection structure 7 includes a second mounting plate 71. On one side of the second mounting plate 71, a second magnetic sheet 72 is provided. The exposed surface of the second magnetic sheet 72 is adsorbed to the exposed surface of the mounting magnetic sheet 24. On one side of the second mounting plate 71, a sliding plate 73 is slidably provided. On the side of the sliding plate 73 close to the second magnetic sheet 72, a reflecting mirror 74 is provided.

[0039] When using this new type of PC laminated plate mold, select the lower surrounding edge structure 3 and the upper surrounding edge structure 4 with corresponding dimensions according to the specified PC board shape. Place the four magnetic box structures 2 on the top surface of the mold table 1. Subsequently, place the engaging plate 37 of the lower surrounding edge structure 3 into the engaging groove 21 at the bottom surface of the magnetic box structure 2 for engagement. Mount the infrared structure 6 on one side of a magnetic box structure 2 through the mounting magnetic sheet 24, and mount the reflection structure 7 on the adjacent magnetic box structure 2 through the mounting magnetic sheet 24. Subsequently, start the infrared lamp 63 and pull the sliding plate 73 to pull out the reflecting mirror 74. Make the light of the infrared lamp 63 irradiate on the reflecting mirror 74. When it is observed that the light path of the infrared lamp 63 is a straight line without refraction, it indicates that the current two magnetic box structures 2 are perpendicular to each other, ensuring the perpendicularity of the corresponding lower surrounding edge structure 3. Repeat the above steps to position the perpendicularity of the four magnetic box structures 2 in sequence. After positioning, start to fix the magnetic box structure 2 on the top surface of the mold table 1. Set a positioning bolt 25 on the top surface of the magnetic box structure 2. The bottom end of the positioning bolt 25 passes through the engaging groove 21 and extends into the engaging plate 37 for positioning. Subsequently, place the upper surrounding edge structure 4 on the top surface of the lower surrounding edge structure 3. The two second upper surrounding magnetic sheets 44 on the bottom surface of the upper surrounding edge structure 4 are positioned and adsorbed to the lower surrounding magnetic sheet 34. At the same time, the positioning pin 46 of the upper surrounding edge structure 4 extends into the lower surrounding positioning ring 35 for positioning. After the upper surrounding edge structure 4 and the lower surrounding edge structure 3 are stacked, the upper surrounding edge contact plate and the lower surrounding edge contact plate are coplanar, forming one side contact edge of the mold. Set a fixing bolt 5 in the setting groove 47. The fixing bolt 5 passes through the setting groove 47 and is connected to the fixing nut 36 at the top end of the lower surrounding edge structure 3. The top end of the fixing bolt 5 presses on the top surface of the stacking cylinder 41 for fixation. It is possible to continue stacking the upper surrounding edge structure 4 on the top surface of the upper surrounding edge structure 4 and then use the corresponding fixing bolt 5 for fixation, thereby expanding the height of the mold surrounding edge and being able to produce PC boards with a higher thickness. By changing the lengths of the upper surrounding edge structure 4 and the lower surrounding edge structure 3, the length and width dimensions of the produced PC board can be changed.
