Specific embodiments

[0034] Please refer to the attached Figures 1 - 3 , which shows a mold device for improving the prefabrication precision of fair - faced concrete wall panels provided by the embodiment of the present application, including: the bottom plate 3, the angle - steel group, the double - sided PE rubber strip, and the wedge - angle strip.

[0035] The bottom plate 3 is made of an integral steel plate with a thickness of 10 - 25 mm, serving as the support surface of the fair - faced concrete wall panel. The angle - steel group is fixedly installed on the bottom plate 3. The angle - steel group is fixed to the bottom plate 3 with bolts, and a double - sided PE rubber strip is arranged between the angle - steel group and the bottom plate 3. The double - sided PE rubber strip can increase the sealing performance at the connection between the angle - steel group and the bottom plate, avoiding the seepage of cement slurry and affecting the quality of the side of the subsequent - formed fair - faced concrete wall panel.

[0036] On the side surface close to the inner side of the angle - steel group, a wedge - angle strip is fixedly installed by screws. The wedge - angle strip is used for forming the wedge opening of the fair - faced concrete wall panel.

[0037] In one embodiment, the wedge angle strip includes: a hollow metal shell 501a, which can adopt a stainless steel thin-wall structure. One side of the hollow metal shell 501a facing the angle steel group is set as an opening. A wooden strip 501b is fixedly arranged inside the hollow metal shell 501a. A T-shaped opening 501c is formed on one side of the wooden strip 501b facing the angle steel group. A T-shaped mounting piece 501d is fixedly connected inside the T-shaped opening 501c. A screw hole 501e is formed on the side of the T-shaped mounting piece 501d.

[0038] Drill holes at the predetermined positions of the angle steel group. Use screws to pass through the holes on the angle steel group and then threadedly connect with the screw holes 501e on the side of the T-shaped mounting piece 501d, so as to realize the stable installation of the wedge angle strip on one side of the angle steel group. The opening side of the hollow metal shell 501a abuts against the side of the angle steel group, and the other surfaces of the angle steel group are all smooth finished surfaces, so as to ensure the forming quality of the wedge opening.

[0041] Using the angle steel structure as the side wall, on the one hand, it is convenient for its stable installation with the bottom plate 3, and on the other hand, the angle steel side wall has better bending resistance, which can ensure the forming quality of the fair-faced concrete hanging board.

[0042] In one embodiment, a second vertical plate 202 is fixedly connected to the bottom of the bottom plate 3 and directly below the first angle steel 401. A first vertical plate 201 is fixedly connected to the bottom of the bottom plate 3 and directly below the second angle steel 402. A third vertical plate 203 is fixedly connected to the bottom of the bottom plate 3 and directly below the third angle steel 403. A fourth vertical plate 204 is fixedly connected to the bottom of the bottom plate 3 and directly below the fourth angle steel 404.

[0043] The first vertical plate 201, the second vertical plate 202, the first vertical plate 20, and the third vertical plate 203 are distributed in a "well" - shaped structure, and are used to support the corresponding parts of the first angle steel 401, the third angle steel 403, the second angle steel 402, and the fourth angle steel 404 on the bottom plate 3.

[0044] In order to better support the bottom plate 3, in one embodiment, the bottom of the bottom plate 3 is fixedly connected with a first channel steel 101 and a second channel steel 102, and both the first channel steel 101 and the second channel steel 102 are in an inverted state.

[0045] The first channel steel 101 and the second channel steel 102 are parallelly distributed.

[0046] In one embodiment, there are four wedge angle strips, and the four wedge angle strips are respectively: a first wedge angle strip 501, a second wedge angle strip 502, a third wedge angle strip 503, and a fourth wedge angle strip 504.

[0047] The first wedge angle strip 501 is installed at the top of the inner side of the first angle steel 401.

[0048] The second wedge angle strip 502 is installed at the bottom of the inner side of the second angle steel 402.

[0049] The third wedge angle strip 503 is installed at the top of the inner side of the third angle steel 403.

[0050] The fourth wedge angle strip 504 is installed at the bottom of the inner side of the fourth angle steel 404.
