Description

Technical Field

[0001] The utility model relates to the field of steel formwork, in particular to an adjustable steel formwork structure. Background Art

[0002] As an indispensable important tool in modern construction, the structural design of steel formwork is directly related to construction efficiency, formwork turnover times and pouring quality.

[0003] Traditional steel formwork structures often adopt fixed-size designs and cannot be flexibly adjusted according to different construction requirements. This results in the frequent replacement of formwork during actual construction, which not only increases construction difficulty and cost, but also reduces construction efficiency. Especially for structures such as building stairs or columns with various different specifications, the limitations of existing steel formwork structures are particularly obvious. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an adjustable steel formwork structure, and solve the following technical problems: how to improve the adaptability and flexibility of the formwork, and how to enhance the sealing performance and stability of the formwork.

[0005] To solve the problems existing in the prior art, the technical scheme adopted by the utility model is as follows:

[0006] An adjustable steel formwork structure includes a plate body and rib plates. There are four plate bodies, which are perpendicular to each other and distributed in a circular array. The four plate bodies are mutually attached to form a square inner cavity. Rib plates are fixedly connected inside the plate bodies. One side of the plate body is fixedly connected with pins at equal intervals. Multiple layers of jacks are arranged in an equidistant horizontal array on the surface of the plate body. Each layer of jacks is at the same horizontal height as the corresponding pins. Each layer of jacks is arranged with several jacks at equal intervals. The pins are slidably inserted into the corresponding jacks.

[0007] Preferably, a strip-shaped hole is opened in the middle of the pin, and a triangular piece is slidably inserted into the strip-shaped hole. After the pin is completely inserted into the jack, the connection stability between the pin and the jack can be enhanced by further inserting the triangular piece, preventing the pin from loosening or falling off due to external pressure or vibration.

[0008] Preferably, a round hole is opened at the top of the triangular piece. The round hole can be used as a connection point for additional reinforcement members, such as fixing the triangular piece more firmly to the plate body through screws or pins to further enhance the connection stability.

[0009] Preferably, a frame is provided at the position corresponding to the pin inside each plate body. Movable blocks are slidably connected at equal intervals inside the frame. One side of the movable block is fixedly connected with a plug, and the plug is slidably inserted into the corresponding jack.

[0010] Preferably, annular grooves are formed around the outer circumference of the movable block, and the top and bottom of the annular grooves are slidably connected to the outside of the frame, ensuring the smoothness and accuracy of the movable block during sliding.

[0011] Preferably, the frame is arranged between the rib plate and one side of the inner wall of the plate body, and the width of the frame is the same as the distance between the rib plate and one side of the inner wall of the plate body, optimizing the internal layout of the template structure and enhancing the support force and stability of the frame.

[0012] Compared with the related technology, the utility model has the following beneficial effects:

[0013] By adjusting the position of the bolt in the jack, the utility model can flexibly adjust the inner cavity size to meet the pouring requirements of columns of different sizes, avoiding the problem that traditional templates need to be frequently replaced due to fixed sizes and improving the construction efficiency.

[0014] The structure design is simple and the assembly is convenient and fast. The four plate bodies are perpendicular to each other and distributed in an annular array. Through the quick connection of the bolt and the jack, the quick assembly and disassembly of the template can be realized, greatly shortening the construction preparation and cleaning time.

[0021] In order to make the objectives, technical solutions and advantages of the utility model more clear and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] The adjustable steel formwork structure has a plate body 1 and a rib plate 2;

[0023] Such as Figures 1 to 5As shown in the figure, there are four plate bodies 1. The four plate bodies 1 are perpendicular to each other and distributed in a circular array. The four plate bodies 1 are attached to each other to form a square inner cavity. There is a rib plate 2 fixedly connected inside the plate body 1. On one side of the plate body 1, there are equally spaced pins 3 fixedly connected. On the surface of the plate body 1, there are multiple layers of jacks 4 arranged in an equidistant horizontal array. Each layer of jacks 4 is at the same horizontal height as the corresponding pin 3. Each layer of jacks 4 is arranged with several equidistant ones. The pin 3 is slidably inserted into the corresponding jack 4;

[0024] The four plate bodies 1 are perpendicular to each other and distributed in a circular array. They are tightly connected by mutual adhesion to jointly form a square inner cavity, which is designed for concrete pouring. Its shape and size directly determine the shape of the finally poured column;

[0025] On one side of each plate body 1, there are equally spaced pins 3, and on the surface, there are multiple layers of jacks 4 arranged in an equidistant horizontal array. During assembly, the pin 3 of one plate body 1 is inserted into the jack 4 of the adjacent plate body 1, thus realizing the tight connection and fixation between the steel formworks. This connection method is not only simple and fast but also ensures the stability and reliability between the steel formworks;

[0026] In order to adapt to the pouring requirements of columns with different sizes, the size of the square inner cavity is changed by adjusting the position of the pin 3 in the jack 4. Specifically, the size of the inner cavity can be adjusted by pulling out the pin 3 from the current jack 4 and inserting it into another jack 4 in the same layer. This flexibility enables this formwork structure to be applicable to the pouring of columns with various sizes.

[0027] As Figures 1 to 5 shown, a strip-shaped hole 5 is opened in the middle of the pin 3, and a triangular piece 6 is slidably inserted into the strip-shaped hole 5;

[0028] After the pin 3 is inserted into the jack 4, the connection between the pin 3 and the jack 4 can be further strengthened by inserting the triangular piece 6 into the strip-shaped hole 5 and making one side of it fit with the frame 8.

[0029] As Figures 1 to 5 shown, a round hole 7 is opened at the top of the triangular piece 6. The round hole 7 at the top of the triangular piece 6 can also be used to connect other reinforcing parts or adjustment tools for more delicate adjustment or reinforcement operations when needed.

[0030] As Figures 1 to 5 shown, at the position corresponding to the pin 3 inside each plate body 1, there is a frame 8. Inside the frame 8, there are equally spaced sliding connection moving blocks 9. One side of the moving block 9 is fixedly connected with a plug 10, and the plug 10 is slidably inserted into the corresponding jack 4;

[0031] To prevent leakage during the pouring of concrete, a frame 8 is provided inside each slab body 1. An active block 9 is slidably connected inside the frame 8. The number of active blocks 9 is one less than the number of jacks 4 in each layer. A plug 10 fixedly connected to one side thereof is used to close the other jacks 4 except the inserted bolt 3. When the bolt 3 is inserted into the jack 4, the active block 9 is slid within the frame 8 to vacate the position corresponding to the jack 4 and close the jacks 4 at other positions, thereby ensuring that the concrete will not leak out from the formwork gap during the pouring process.

[0032] As Figures 1 to 5 shown, an annular groove 11 is provided around the outer circle of the active block 9. The top and bottom of the annular groove 11 are slidably connected to the outside of the frame 8, allowing the active block 9 to slide horizontally and stably within the frame 8 and not be separated from the frame 8.

[0033] As Figures 1 to 5 shown, the frame 8 is provided between the rib plate 2 and one side of the inner wall of the slab body 1. The width of the frame 8 is the same as the distance between the rib plate 2 and one side of the inner wall of the slab body 1. When the frame 8 is taken and placed, it can be stuck between the rib plate 2 and the inner wall of the slab body 1 without external force.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
