Description

Technical Field

[0001] The utility model relates to the technical field of building wall panels, in particular to a forming and demoulding structure for a partition wall panel blank body. Background Art

[0002] A partition wall panel refers to a precast strip panel used for non-load-bearing parts inside a building. Partition wall panels include glass fiber reinforced cement strip panels (GRC panels), glass fiber reinforced gypsum hollow strip panels (GRG panels), pressurized aerated concrete strip panels (ALC panels), steel wire (steel wire mesh) reinforced cement strip panels, lightweight concrete strip panels, composite sandwich lightweight strip panels, etc. The full name is lightweight strip panels for building partition walls, which are the main materials for non-load-bearing internal partition walls in general industrial buildings, residential buildings, and public building projects.

[0003] In the production process of concrete partition wall panels, concrete or recycled concrete is poured into a mold for forming. The mold becomes an important device for producing precast wall panels. For example, in a Chinese utility model patent with the publication number CN206780607U, a side mold layered precast concrete wall panel mold is disclosed, which includes four side molds, namely an upper side mold, a lower side mold, a left side mold, and a right side mold. Vertical rib plates are provided on all four side molds; the upper side mold and the lower side mold of the precast concrete wall panel adopt an integral side mold, and circular holes are opened at the corresponding positions of the upper side mold and the lower side mold for steel bars; the left side mold and the right side mold of the precast concrete wall panel adopt a layered side mold, and the structures of the left side mold and the right side mold are symmetrical; the layered side mold, including the left side mold and the right side mold, both include three layers, namely an upper layer, a middle layer, and a lower layer, and the upper layer, the middle layer, and the lower layer are connected into an integral body through through-long rod bolts.

[0004] When demoulding the mold in the above application, first assemble the four side molds and tie the steel bars; after the steel bars are tied, pour the precast concrete wall panel. After the concrete reaches the demoulding strength, remove the upper side mold and the lower side mold. For the left side mold and the right side mold, first remove the upper layers of the left and right side molds, then horizontally extract the middle layers of the left and right side molds from the steel bar cage along the length direction of the side mold, and finally lift the precast concrete wall panel and disassemble the lower layers of the left and right side molds to complete the mold demoulding. When demoulding, it is necessary to disassemble the upper side mold, the lower side mold, the left side mold, and the right side mold, which is generally troublesome and affects the convenience of demoulding.

[0021] See also Figures 1 to 2 In this embodiment, a partition board blank forming demoulding structure comprises a bottom plate 1, an upper end of the bottom plate 1 is fixedly connected to a column 2, and a demoulding member 3 is provided on the column 2 and the bottom plate 1;

[0022] The demolding member 3 includes a first side plate 31 with one end hinged to the upper end of the bottom plate 1. A second side plate 32 is hinged to the upper end of the bottom plate 1. A cross plate 33 is fixedly connected to the upper end of the column 2. A cylinder 35 with one end penetrating through the cross plate 33 is fixedly installed at the upper end of the cross plate 33. The output end of the cylinder 35 is fixedly connected to a driving plate 34. A first inclined rod 36 with one end hinged to the first side plate 31 is hinged to the lower end of the driving plate 34. A second inclined rod 37 with one end hinged to the second side plate 32 is hinged to the lower end of the driving plate 34.

[0023] In this embodiment, when the cylinder 35 is started, the first side plate 31 and the second side plate 32 are pulled by the first inclined rod 36 and the second inclined rod 37 to enclose a rectangular cavity, and then concrete can be poured. Before pouring the concrete to form the partition board blank, the cylinder 35 drives the driving plate 34 to move downwards, and then the first side plate 31 and the second side plate 32 are simultaneously pushed away from the concrete by the first inclined rod 36 and the second inclined rod 37 to improve the demolding convenience.

[0024] Among them, the number of columns 2 is four. The four columns 2 are symmetrically distributed in pairs at the four corners of the bottom plate 1. A circular hole located outside the column 2 is formed inside the driving plate 34. While the cross plate 33 is stably supported by the four columns 2, the driving plate 34 can also be stably moved up and down.

[0025] In addition, the number of both the first side plate 31 and the second side plate 32 is two. The two first side plates 31 are symmetrically distributed front and back on the bottom plate 1.

[0026] Secondly, the two second side plates 32 are symmetrically distributed left and right on the bottom plate 1. The first side plate 31 and the second side plate 32 are both hinged to the bottom plate 1 through hinges.

[0027] Please refer to Figures 2 to 3 , in this embodiment, a first connection block 310 is fixedly connected to the outer side of the first side plate 31, a second connection block 311 is fixedly connected to the outer side of the second side plate 32. An insertion block 312 is inserted into the outer sides of the first connection block 310 and the second connection block 311. An insertion rod 313 with one end extending into the inside of the second connection block 311 is fixedly connected to the inner side of the insertion block 312. A sleeve rod 39 is fixedly connected to the outer side of the insertion block 312. A threaded rod 38 is threadedly connected to the inner side of the sleeve rod 39.

[0028] In this embodiment, before pouring the concrete to form the partition board blank, the insertion block 312 can be inserted outside the first connection block 310 and the second connection block 311, and the first side plate 31 and the second side plate 32 in contact are locked by rotating the threaded rod 38 to improve the pouring quality. After the concrete solidifies and forms, the insertion block 312 can be pulled out.

[0029] Among them, the number of the first connecting blocks 310 is four, and the four first connecting blocks 310 are symmetrically distributed in two groups of two on the two first side plates 31. The number of the second connecting blocks 311 is four, and the four second connecting blocks 311 are symmetrically distributed in two groups of two on the second side plate 32.

[0030] In addition, an internal thread is provided on the inner peripheral wall of the sleeve rod 39, and the internal thread cooperates with the thread on the outer side of the threaded rod 38. The thread on the outer side of the threaded rod 38 has two sections, and the two sections of the thread are symmetrically distributed, so that the rotating threaded rod 38 can drive the sleeve rods 39 on both sides to move towards the side close to the screw rod 38.

[0031] Secondly, the insertion block 312 is U-shaped, and a slot located outside the insertion rod 313 is provided at the upper end of the second connecting block 311. Through the insertion rod 313 inserted into the slot, when the rotating threaded rod 38 drives the sleeve rod 39 to approach, the insertion rod 313 can drive the second connecting block 311 and the second side plate 32 to closely fit the first side plate 31.

[0032] The working principle of the above embodiment is as follows:

[0033] The started cylinder 35 pulls the first side plate 31 and the second side plate 32 through the first inclined rod 36 and the second inclined rod 37 to enclose a rectangular cavity, and then concrete can be poured. Before pouring concrete to form the partition board blank, the insertion block 312 can be inserted outside the first connecting block 310 and the second connecting block 311, and by rotating the threaded rod 38, the sleeve rods 39 on both sides can be driven to move towards the side close to the threaded rod 38, and the second connecting block 311 and the second side 32 can be pulled through the insertion rod 313 on the insertion block 312 to closely fit the first side plate 32, so as to lock the fitted first side plate 31 and the second side plate 32 to improve the pouring quality. After the concrete solidifies and forms, after the insertion block 312 is withdrawn, the cylinder 35 can be driven to drive the driving plate 34 to move downward, and then the first side plate 31 and the second side plate 32 can be simultaneously pushed by the first inclined rod 36 and the second inclined rod 37 to separate from the concrete to improve the demoulding convenience.
