Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and in particular relates to a steel formwork platform for assembled building production. Background Art

[0002] In recent years, with economic development, prefabricated buildings have developed rapidly. Compared with traditional building construction, prefabricated buildings have short construction time, high construction efficiency and environmentally friendly construction methods. Prefabricated buildings specifically divide the house into multiple components, manufacture the components in the factory, and use steel molds to pour concrete inside to make building products. These building products are transported to the construction site for assembly and cast-in-place connection into buildings. This construction method is environmentally friendly, can reduce the pollution caused by on-site construction, and greatly improves construction efficiency.

[0003] However, there are some problems with the prior art: the existing steel formwork platform is also provided with an inner mold, so that an inner cavity can be left in the middle of the building product made after pouring concrete. In order to prevent the inner mold from being displaced by the poured concrete and affecting the production quality, the staff needs to use a connecting frame to connect and fix the outer mold with the inner mold. However, the staff often needs to select inner molds of different sizes according to processing requirements, so different types of connecting frames are required to connect the inner mold with the outer mold, which increases the production cost. Therefore, we propose a steel formwork platform for prefabricated building production. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a steel formwork platform for prefabricated building production, which is convenient for connecting inner molds of different sizes by providing an adjustable connecting frame.

[0005] The utility model is implemented as follows: a steel mold platform for assembled building production comprises an outer mold body, an inner mold body is movably installed at the bottom of the inner cavity of the outer mold body, a connecting frame body is arranged between the tops of the outer mold body and the inner mold body, the connecting frame body and the outer mold body are connected by bolts, a guide rod is fixedly installed on the connecting frame body, a movable plate is slidably sleeved on the outer surface of the guide rod, the movable plate and the inner mold body are connected by a bayonet pin assembly, a square groove is provided on the guide rod, a bidirectional screw rod is rotatably connected to the movable plate, and sliders are threadedly connected on both sides of the outer surface of the bidirectional screw rod.

[0006] Optionally, a circular groove is formed on the inner mold body, and the bayonet assembly includes a latch pin, which is movably plugged into the connecting frame body, and the bottom of the latch pin extends into the circular groove, and the top of the latch pin is fixedly connected with a pull handle.

[0007] Optionally, a spring is movably sleeved on the outer surface of the latch, and two ends of the spring are respectively fixedly connected to the outer surfaces of the movable plate and the handle.

[0008] Optionally, a sheath is fixedly sleeved on the outer surface of the bidirectional screw rod, and an outer surface of the sheath is provided with anti-slip grooves.

[0009] Optionally, a pad is fixedly mounted on the bottom of the inner mold body, and the bottom of the pad is attached to the bottom of the inner wall of the outer mold body.

[0010] Optionally, the outer mold body is fixedly mounted with lifting ears, the lifting ears are arranged in at least two groups, and the two groups of lifting ears are symmetrically distributed.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model provides a movable plate, a bidirectional screw rod and a slider. When the length dimension of the inner mold body changes, the staff can rotate the bidirectional screw rod to make the two sliders move toward each other and be drawn out from the inside of the square groove, thereby releasing the limiting effect on the movable plate. Subsequently, after adjusting the position of the movable plate according to the length dimension of the inner mold body, the bidirectional screw rod is rotated again to make the two sliders move away from each other and be inserted into the square groove at the corresponding position. Then, the inner mold body is limited by the pin assembly, thereby achieving the effect of being able to connect inner mold bodies of different sizes, improving applicability and reducing production costs.

[0020] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 5 As shown, an embodiment of the utility model provides a steel mold platform for prefabricated building production, including an outer mold body 1, an inner mold body 2 is movably installed at the bottom of the inner cavity of the outer mold body 1, a connecting frame body 3 is arranged between the tops of the outer mold body 1 and the inner mold body 2, the connecting frame body 3 and the outer mold body 1 are connected by bolts 4, a guide rod 5 is fixedly installed on the connecting frame body 3, a movable plate 6 is slidably sleeved on the outer surface of the guide rod 5, the movable plate 6 and the inner mold body 2 are connected by a bayonet pin assembly, a square groove 7 is opened on the guide rod 5, a bidirectional screw rod 8 is rotatably connected to the movable plate 6, and sliders 9 are threadedly connected to both sides of the outer surface of the bidirectional screw rod 8.

[0022] Furthermore, a circular groove 10 is formed on the inner mold body 2, and the latch assembly includes a latch 11, which is movably plugged into the connecting frame body 3, and the bottom of the latch 11 extends into the circular groove 10, and the top of the latch 11 is fixedly connected with a handle 12.

[0023] After the staff fixes the connecting frame body 3 on the outer mold body 1 by bolts 4, and then inserts the pin 11 into the circular groove 10, the inner mold body 2 can be limited, thereby preventing the inner mold body 2 from being squeezed and moved after pouring concrete between the inner cavity of the outer mold body 1 and the inner mold body 2, affecting the processing quality of the building prefabricated parts.

[0024] Furthermore, a spring 13 is movably sleeved on the outer surface of the latch 11 , and two ends of the spring 13 are fixedly connected to the outer surfaces of the movable plate 6 and the handle 12 , respectively.

[0025] By setting the spring 13 to a stretched state, the latch 11 will tend to move downward due to the elastic recovery effect of the spring 13, so that the bottom of the latch 11 can be stably maintained inside the circular groove 10, thereby ensuring the limiting effect on the inner mold body 2.

[0026] Furthermore, a sheath 14 is fixedly sleeved on the outer surface of the bidirectional screw rod 8 , and an outer surface of the sheath 14 is provided with anti-slip grooves.

[0027] The anti-skid pattern on the outer surface of the sheath 14 can increase the friction between the worker's hand and the sheath 14 . At the same time, the sheath 14 can be made of silicone, so that the worker can hold the sheath 14 and rotate the bidirectional screw rod 8 more stably and comfortably.

[0028] Furthermore, a cushion block 15 is fixedly installed at the bottom of the inner mold body 2 , and the bottom of the cushion block 15 is attached to the bottom of the inner wall of the outer mold body 1 .

[0029] The pad 15 can be made of rubber. Since rubber has good elasticity, the pad 15 can be pressed to make it fit tightly with the outer mold body 1, thereby improving the sealing and preventing concrete slurry from flowing from the bottom of the inner mold body 2 into the inner cavity of the inner mold body 2.

[0030] Furthermore, the outer mold body 1 is fixedly mounted with lifting ears 16 , and the lifting ears 16 are arranged in at least two groups, and the two groups of lifting ears 16 are symmetrically distributed.

[0031] The design of the lifting lug 16 makes it easy for the staff to lift and transfer the outer mold body 1 as a whole, thereby facilitating the transfer of concrete to different stations for oscillation and curing for production and processing.

[0032] During use, the staff hoist the inner mold body 2 to the inside of the outer mold body 1 and then need to adjust the position of the movable plate 6 according to the size of the inner mold body 2 so as to use the pin 11 to limit the inner mold body 2. When adjusting the position of the movable plate 6, the staff can first rotate the two-way screw rod 8 to make the two sliders 9 move toward each other and be pulled out from the inside of the square groove 7, thereby releasing the limiting effect on the movable plate 6. Subsequently, after adjusting the position of the movable plate 6 according to the length of the inner mold body 2, the two-way screw rod 8 is rotated again to make the two sliders 9 move back to back and insert into the square groove 7 at the corresponding position. After the position of the movable plate 6 corresponds to that of the inner mold body 2, due to the elastic recovery effect of the spring 13, the pin 11 will be inserted into the inside of the circular groove 10. Then the staff can fix the connecting frame body 3 on the outer mold body 1 by the bolt 4, thereby completing the limiting of the inner mold body 2 and avoiding the inner mold body 2 from being impacted and moved when pouring concrete, affecting the production quality.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
