In the demolding process, after the side templates are required to be completely removed along the horizontal ribs, demolding and hoisting of the shear wall can be performed, and a series of operations such as position adjustment, alignment and leveling are required to be performed again. The required procedures are more, the repeated utilization rate is lower, and then the engineering cost is increased. In view of the above, the application provides a die for producing a prefabricated shear wall, which reduces the labor required by an operation flow, improves the recycling rate and further reduces the engineering cost.

Referring to fig. 1-2, a prefabricated shear wall production mold provided by an embodiment of the present application includes two side frames disposed opposite to each other, and two end frames 100 disposed opposite to each other; the two side frames and the two end frames 100 are combined into a rectangular frame-shaped die, the two side frames and the two end frames 100 are positioned, leveled and straightened on a die table, the two side frames are fixed through a pressing piece sliding on the die table, and the two end frames 100 are connected to the two ends of the two side frames through first bolt assemblies and then fixed after being positioned.

In the embodiment of the present application, the two end frames 100 are integrated into a box plate, and the two side frames are combined by using the split upper mold 300 and the lower mold 200. And, the two side frames and the two end frames 100 are combined into a frame-shaped mold having the same level inside. Ensuring the surface smoothness of the prefabricated member. It can be seen that the heights of the upper mold 300 and the lower mold of any one side frame are the same as the heights of the two end frames 100, respectively, after being added.

In the processing process of the prefabricated member of the shear wall, a reinforcement cage is required to be arranged, meanwhile, in order to ensure the firmness and reliability in the installation process of the shear wall, horizontal ribs on two sides are exposed, and part of the horizontal ribs on the two sides are exposed as well as the reinforcement bars on the upper end and the lower end. When the shear wall is prefabricated at the present stage, after the templates are placed in position, the reinforcement cages are bound on site, the operation time required for horizontal ribs to pass through the templates is long, the reinforcement cages are very inconvenient to bind between the templates, and meanwhile, the templates on the side edges need to be completely taken out along the exposed horizontal ribs in the demolding process. The template is required to be positioned again, more workers are required for the whole working procedure, and the operation is complex.

For this reason, in the present application, two end frames 100 are used as the upper end mold and the lower end mold, and in order to meet the requirement that the upper end and the lower end need to be exposed with reinforcing steel bars, the two end frames 100 are provided with reinforcing steel bar holes. And the two end frames 100 are respectively provided with lifting lugs. The two side frames are vertically hung between the two lower mold bodies 200 by the reinforcement cage pre-bound on the platform after the upper mold body 300 is removed. Because the two lower mold bodies 200 are fixed on the mold table by the pressing plate, the two lower mold bodies 200 are respectively provided with a plurality of rib-distributing waist holes 250 for exposing the horizontal ribs of the side parts. Thereby realize the ligature steel reinforcement cage on comparatively convenient mesa, easy operation, directly with the horizontal muscle behind the cloth muscle waist hole 250 position relatively, the steel reinforcement cage hangs into between two lower die bodies 200, is connected with two lower die bodies 200 after assembling two tip frames 100 positioning. The upper mold body 300 is correspondingly installed on the two lower mold bodies 200, so that a casting space having the same level is formed inside between the two end frames 100, the two lower mold bodies 200 and the two upper mold bodies 300.

In connection with the illustration in fig. 3, a plurality of protruding shear members 210 are mounted on the mutually facing surfaces of the two lower mold bodies 200, the shear members 210 being screwed to the lower mold bodies 200. Thereby ensuring that the side roughness of the shear wall meets the standard requirements. Meanwhile, in the process of pouring concrete, the gap spaces of the plurality of rib-distributing waist holes 250 or the rib-discharging holes can be plugged by plugging pieces, and the plugging pieces can be foam strips, adhesive tapes and the like.

In the demoulding process, for the shear wall with no exposed steel bars at the two ends, the two upper mould bodies 300 are removed, the pressing plate pieces on the mould platforms are loosened, the first bolt assemblies between the two end frames 100 and the two lower mould bodies 200 are loosened, the shear pieces 210 of the two lower mould bodies 200 are separated from the shear wall, and the shear wall is vertically hoisted to realize demoulding. And when the die is assembled again, the pressing piece and the first bolt component are continuously screwed and fixed. For the shear wall with exposed steel bars at two ends, the two upper die bodies 300 are dismounted, the pressing plates on the die tables are loosened, the first bolt assemblies between the two end frames 100 and the two lower die bodies 200 are completely loosened, the shear members 210 of the two lower die bodies 200 are separated from the shear wall, the lifting lugs of the two end frames 100 are vertically lifted, and the two end frames 100 are dismounted after the shear wall is lifted to a proper position. When the die is assembled again, the pressing plate piece is screwed and fixed, after the reinforcement cage is put in, the reinforcement extending along the two ends of the reinforcement cage passes through the reinforcement outlet holes of the two end frames 100, and after the two end frames 100 are adjusted at the proper installation positions, the two lower die bodies 200 are connected through the first bolt assemblies.

Referring to fig. 4, when the supporting strength and the installation effect of the mold for producing the integral precast shear wall are specifically achieved, the opposite sides of the two end frames 100 are provided with the first reinforcing rib plates 110. Thereby enhancing the supporting strength of the two end frames 100.

Each side frame includes: a lower mold body 200, and an upper mold body 300 coupled to cover the top of the lower mold body 200; the lower die body 200 is provided with a plurality of rib-distributing waist holes 250 at intervals along the length direction thereof, and the plurality of rib-distributing waist holes 250 penetrate through the top of the lower die body 200 and extend towards the vertical direction of the lower die body 200; it can be seen that the rib-distributing waist hole 250 penetrates through the top of the lower die body 200, and the lower die body 200 also adopts a box plate, and the rib-distributing waist hole 250 extends along the vertical face of the lower die body 200, so that a long waist through hole in a right-angle bending shape is formed, and the long waist through hole and a side horizontal rib enter between the two lower die bodies 200 from the top of the lower die body 200.

Because the lower die body 200 is provided with the plurality of through-hole-shaped rib-distributing waist holes 250, in order to improve the supporting strength of the lower die body 200 and achieve a certain weight reduction purpose, a plurality of second reinforcing rib plates 220 are arranged on the opposite sides of the two lower die bodies 200 along the length direction at intervals, and each second reinforcing rib plate 220 is provided with a weight reduction through hole 221. The strength of the two lower mold bodies 200 is enhanced and weight reduction is performed.

The two sides of each end frame 100 are provided with first positioning holes 120, and at least two first positioning holes 120 are arranged on each side, so that the end frames 100 are prevented from forming axle center rotation after being installed; the two ends of each lower die body 200 are respectively provided with a plurality of groups of positioning holes 240 in an arrangement mode, the arrangement direction is that the positioning holes are arranged along the length direction of the lower die body 200, and each group of positioning holes 240 are at least two along the height direction of the lower die body 200, so that the holes of each group of positioning holes 240 are overlapped with the corresponding first positioning holes 120 in a one-to-one correspondence mode. The first positioning holes 120 on any side are overlapped with a corresponding group of positioning holes 240 and then are fixedly connected through a first bolt assembly. Through detachable connected mode, the mode of adjusting a position is succinct, and installation location is more convenient. Thus, after the two end frames 100 are installed between the two lower mold bodies 200, the two end frames are fixedly connected through the first bolt assembly, and are loosened or removed in the demolding process, so that demolding gaps are ensured to exist, and the whole installation and removal are more convenient.

The top of the lower die body 200 is provided with a plurality of second positioning holes 230 along the length direction, and the upper die body 300 is provided with third positioning holes 320 which are overlapped with the second positioning holes 230 in a one-to-one correspondence manner; any one of the third positioning holes 320 is overlapped with the corresponding second positioning hole 230 and then is fixedly connected through the second bolt assembly. Through detachable connected mode, the installation location is more convenient. In order to enhance the supporting strength of the upper mold 300, the upper mold 300 is a right angle bending mold, the vertical surface of the upper mold 300 and the vertical surface of the lower mold 200 are located on the same plane, and the width and length of the bottom plane of the upper mold 300 and the top plane of the lower mold 200 are the same. Meanwhile, a plurality of third reinforcing ribs 310 are provided at intervals along the length direction of one surface of the two upper mold bodies 300 facing away from each other. Thereby enhancing the strength of the two upper mold bodies 300. It should be specifically noted that, in the present application, the first bolt assembly and the second bolt assembly are both bolts and nuts 400, and the types may be the same or may be installed in an optional manner.

It can be seen that when the upper mold 300 is connected with the lower mold 200, the bottom plane of the upper mold 300 shields the tops of the plurality of rib-distributing waist holes 250; when the upper die body 300 is separated from the lower die body 200, the upper die body 300 avoids the plurality of rib-distributing waist holes 250. The upper mold 300 is convenient to hang the reinforcement cage in and hang the prefabricated member out when avoiding the plurality of reinforcement waist holes 250.

According to the application, through the pre-bound reinforcement cage, after the horizontal reinforcement is opposite to the reinforcement waist holes 250, the reinforcement cage is vertically hung between the two lower die bodies 200, so that the time for the former reinforcement cage to pass through a die is reduced, and the die-filling reinforcement-arranging process can be shortened to 15 minutes from 50 minutes in the original traditional scheme. In the demoulding process of pouring, the pressing plate piece on the mould platform is loosened, the upper mould body 300 is detached after the second bolt assembly is removed, a vertical hanging gap exists between the shear wall and the mould after the first bolt assembly is loosened or removed, the whole operation procedure is simple and convenient, the time consumption is less, and the repeated use rate is improved.

According to the utility model, the pre-bound reinforcement cage is hoisted between the two lower die bodies 200 along the plurality of reinforcement-distributing waist holes 250, so that the problems of inconvenient operation and long time consumption caused by site reinforcement distribution are reduced; meanwhile, in the demolding process, the upper mold body 300 is removed to enable the prefabricated member to be vertically lifted out, the operation is simple and convenient, and less labor is required in the operation flow. Meanwhile, when the die is assembled again, the time for positioning, leveling and straightening is shortened, the production line efficiency is improved, the recycling rate is improved, and the engineering cost is further reduced.
