[0027] Embodiment 1:

[0028] like Figure 1 to Figure 3 As shown, a prefabricated wall panel mold for an assembled building comprises a bottom plate 1, a pair of outer templates 2 arranged opposite to each other are arranged on the bottom plate 1, one or more sets of middle templates 3 are arranged between the pair of outer templates 2, and the middle templates 3 and the outer templates 2 are respectively provided with detachable side templates 4 at both ends in the length direction, or the side templates 4 are respectively arranged between the middle templates 3 and the middle templates 3, and between the middle templates 3 and the outer templates 2 (such as Figure 4 As shown); a plurality of vertical poles 5 are respectively provided on the outer side of the outer formwork 2, and the vertical poles 5 are higher than the outer formwork 2, and a pair of opposite vertical poles 5 are connected with detachable tension screws 6 at the raised parts; a plurality of support seats 7 are respectively provided on both sides of the base plate 1, and an adjustable top rod assembly 8 is provided between the support seat 7 and the vertical poles 5; a plurality of exciters 10 are also provided on the outer side of the outer formwork 2.

[0029] The prefabricated wall panel mold for assembled buildings has a simple structure, is easy to make and use, and can mass-produce prefabricated concrete wall panels with high production efficiency. It also has good flexibility and controllability, and can produce multiple prefabricated concrete wall panels of different thicknesses in the same set of molds, thereby improving the application range of the mold.

[0030] The space enclosed by the outer formwork 2, the middle formwork 3 and the side formwork 4 on the base plate 1 is the cavity for pouring concrete, and the opening on the top can be used as a pouring channel. The raw materials for pouring are different depending on the material of the wall panel. This embodiment takes concrete material as an example; after the outer formwork 2, the middle formwork 3 and the side formwork 4 are assembled, steel bars, inner molds and other components for final molding can be set in the cavity as needed; some molding structures can also be set on the inner side of the outer formwork 2 and the two sides of the middle formwork 3 as needed, so that they can be formed together when pouring concrete.

[0031] The vertical rod 5 is welded to the outside of the outer formwork 2. On the one hand, the high part thereof is used to connect the tension screw 6 to lock these formworks, and on the other hand, it is used as a reinforcement structure to enhance the strength and stability of the outer formwork 2. The support seat 7 is arranged on the bottom plate 1 and connected to the top rod assembly 8, so that a clamping structure can be formed below the outer formwork 2 to further lock these formworks. The bottom plate 1 is used as both a supporting base and a bottom formwork. The outer formwork 2, the middle formwork 3 and the side formwork 4 can be vertically placed on the bottom plate 1 by their own gravity, and the locking of both sides can play a stabilizing role. After the pouring is completed, the outer formwork 2, the middle formwork 3 and the side formwork 4 can also be demolded very conveniently. After the concrete prefabricated wall panels are hardened, the locking of the tension screws and the top rod assembly is released, and the side formwork 4, the outer formwork 2 and the middle formwork 3 are removed to complete the demolding. When these prefabricated wall panels are taken out for maintenance, these formworks can be put into use again.

[0032] The vibrator 10 is arranged on the outer formwork 2 to generate a vibrating force, which is beneficial to the downward movement and uniform distribution of concrete, so that the prefabricated wall panels with long strip structures have better density and avoid the defect of insufficient pouring at the bottom; this also avoids manual vibration, reduces manual labor, and improves the vibration efficiency.

[0033] Furthermore, vertical insertion grooves 11 are respectively provided on the inner side of the outer template 2 and on both sides of the middle template 3. The insertion grooves 11 are used to connect the side templates 4. The insertion grooves 11 have a draft angle of 1 to 3 degrees. It is convenient to connect the side templates using the insertion grooves 11. The setting of the draft angle is conducive to demoulding.

[0034] Furthermore, the push rod assembly 8 includes a threaded push rod 801 and a rotating handle 802 disposed at the outer end of the threaded push rod 801. The support seat 7 is provided with an internal threaded hole connected to the threaded push rod 801. The end of the threaded push rod 801 is provided with a pad and abuts against the outer side of the vertical rod 5. The threaded push rod 801 can be driven to move forward and backward by rotating the rotating handle 802, and the outer template 2 can be tightened and locked while adjusting the spacing.

[0035] Furthermore, a mounting seat 9 is provided on the outer side of the outer formwork 2, and the exciter 10 is provided on the mounting seat 9, and the exciter 10 is a linear vibrator; a rubber support is provided below the base plate 1. The mounting seat 9 can be fixed on the outer formwork by welding or bolting, and after the linear vibrator is installed, a directional and orderly vibration force can be provided, which will be transmitted to the concrete material in the cavity, which is conducive to the uniform distribution of the concrete material and the discharge of the enclosed gas inside.

[0036] In some embodiments, the bottom surfaces of the outer template 2, the middle template 3 and the side template 4 are respectively provided with sealing grooves, and sealing strips are provided in the sealing grooves. In practice, sealing members may not be provided. If the templates do not fit well and there is leakage, sealing members may still be required. In this embodiment, sealing strips are provided on the bottom surfaces of these templates, which can play a role in bottom sealing. During the installation process, the sealing strips can be tightly fitted to form a sealing structure by relying on the deadweight of the outer template, the middle template and the side template.

[0037] The outer formwork 2, the middle formwork 3 and the side formwork 4 are respectively welded steel structures, and steel plates and channel steels are mostly used. The thickness of the steel plate is not less than 4 mm. Some ribs and frame structures are also welded on the outside of the outer formwork 2, so it has a certain weight and can bear the pouring of large-volume concrete; the sides of the outer formwork, the middle formwork and the side formwork are also respectively provided with lifting points, which can be lifting holes, lifting rings, lifting handles, etc., which are convenient for moving these formworks by lifting. There are cranes or electric hoists in the prefabrication workshop, and lifting is also relatively convenient.

[0038] Furthermore, the length of the outer formwork 2 is at least 1.5 m, the height of the outer formwork 2 is not greater than 0.5 m, and the number of the vertical poles 5 is at least three pairs arranged at equal intervals. Large-volume prefabricated wall panels can be produced.

[0039] Embodiment 2:

[0040] This embodiment provides a scraper that is easy to use based on the first embodiment.

[0041] like Figure 5 and Figure 6 As shown, a movable scraper assembly is also provided above a pair of the outer mold plates 2, and the scraper assembly includes a supporting slide bar 12 arranged on the outer mold plate 2, a detachable connecting rod 13 is provided between the pair of supporting slide bars 12, and a plurality of scraper groups 14 are provided below the connecting rod 13.

[0042] By setting the supporting slide bar 12, the connecting rod 13 can be driven to move along the top of the assembled mold, and the concrete above each cavity can be scraped flat by using the scrapers 14 arranged at intervals. The scraper assembly is arranged in a movable manner, which is convenient for the operator to push or pull it to move, so as to complete the scraping operation of multiple concrete pouring areas at the same time, which greatly improves the scraping efficiency and reduces the burden on workers. The movement of the scraper assembly can also be driven by a motor.

[0043] The connecting rod 13 is detachable, and connecting rods of different lengths can be selected according to the width of the mold. The spacing and position of the scraper 14 can also be adjusted so that it can scrape the concrete between the middle templates or between the middle template and the outer template.

[0044] Furthermore, the outer formwork 2 is provided with a slide groove or a slide rail connected to the support slide rod 12, and a moving wheel or a slider can be provided at the lower end of the support slide rod 12 to facilitate its movement; the height of the support slide rod 12 is lower than the height of the tension screw rod 6 to ensure that it can pass under the tension screw rod 6.

[0045] A connecting sleeve 15 is provided above the scraper 14, and the connecting sleeve 15 is sleeved on the connecting rod 13 and fixed by a locking member, such as a locking screw 16. Through such a configuration, the scrapers can be conveniently adjusted and fixed.
