Technical Field

[0001] The utility model relates to the technical field of steel formwork, in particular to a self-locking steel formwork for a frame column. Background Art

[0002] Steel formwork is a steel formwork used for concrete pouring. In addition to steel formwork, there are also wooden formwork, plywood formwork, etc. Steel formwork is widely used in the forming and production of building structures such as frame columns due to its multiple uses and beautiful concrete pouring.

[0003] The frame column is the main vertical support structure that bears the load from the beams and slabs in the frame structure and transmits the load to the foundation. When making the frame column, it is necessary to first tie the steel bars to form a steel cage, then set up a steel formwork outside the steel cage, and then pour concrete into the steel formwork. After the concrete solidifies, the formwork is removed to form a frame column.

[0004] Traditional steel formworks are usually customized according to the shape and size of frame columns and are only suitable for frame columns of set sizes. In order to meet the manufacturing needs of frame columns of different specifications and sizes on the construction site, it is feasible to design the same steel formworks of different sizes separately, but it is inconvenient to manage many steel formworks of different sizes.

[0006] A self-locking steel formwork for a frame column comprises a frame column and a steel formwork arranged on the outside of the frame column, wherein the steel formwork comprises two long formworks and two short formworks which cooperate and abut against the outer side surface of the frame column, wherein the two short formworks are detachably arranged between two adjacent long formworks, and two groups of side plates which are symmetrically distributed and cooperate and abut against the long formworks are fixedly arranged on the side of the short formwork away from the frame column, wherein matching self-locking bolts are movably arranged in the side plates, wherein a plurality of groups of connecting holes are opened on one side of the long formwork, wherein one end of the self-locking bolt is threadedly connected in the connecting hole, and wherein a blocking mechanism is arranged in the connecting hole for blocking concrete flowing toward the connecting hole when pouring concrete.

[0007] By adopting the above technical solution, the cross-sectional size of the steel formwork is adjusted by using connection holes at different positions for formwork assembly, which is suitable for manufacturing frame columns with different cross-sectional sizes.

[0008] Optionally, the blocking mechanism includes a spring fixed on the inner side of the connecting hole, and a cover plate fixed on one end of the spring for sealing the opening of the connecting hole, a fixing ring is fixed on the side of the cover plate close to the spring, a sealing ring is fixed on the outer wall of the fixing ring for sealing the connection between the cover plate and the long template, and a plurality of groups of air guide holes communicating with the connecting hole are provided on the side of the long template facing away from the frame column.

[0009] By adopting the above technical solution, the blocking structure inner cover plate blocks the opening of the connection hole, and the sealing of the sealing ring is used to prevent the poured concrete from entering the connection hole and solidifying and fixing it, making it inconvenient to clean.

[0010] Optionally, a sleeve hole is provided at the screw end of the self-locking bolt, and a round ball is rotatably provided in the sleeve hole of the self-locking bolt and abuts against the cover plate.

[0015] 1. By connecting two long templates and two short templates, and using self-locking bolts for self-locking and fixing, and coordinating with adjustable diagonal braces, hoop-free construction is achieved. The cross-sectional size of the steel template is adjusted by using connection holes in different positions for template assembly. It is suitable for the manufacture of frame columns with different cross-sectional sizes. The overall installation and reinforcement is convenient and fast, with a large number of turnovers and can adapt to a variety of cross-sections, which greatly reduces the number of template configurations and facilitates management.

[0016] 2. By blocking the opening of the connection hole with the cover plate inside the blocking structure and cooperating with the sealing of the sealing ring, it can prevent the poured concrete from entering the connection hole and solidifying and fixing it inconvenient to clean. Moreover, through the transfer of the ball, it can reduce the wear of the cover plate when the self-locking bolt rotates, thereby extending the service life of the cover plate, which is convenient and practical.

[0022] The following is combined with Figure 1-4 The utility model is described in further detail.

[0023] The utility model embodiment discloses a self-locking steel mold for frame columns, referring to Figure 1 , including a frame column 1, and a steel template arranged on the outside of the frame column 1, the steel template includes two long templates 2 and two short templates 3 that are matched and abutted against the outer side of the frame column 1, the two short templates 3 are detachable and arranged between two adjacent long templates 2, and the two long templates 2 and the two short templates 3 are assembled to form a fixed steel template for the frame column 1.

[0024] Reference Figure 1-3 Two groups of side plates 31 are fixedly provided on the side of the short formwork 3 away from the frame column 1, which are symmetrically distributed and cooperate with the long formwork 2. Matching self-locking bolts 32 are movably provided in the side plates 31. A plurality of connecting holes 21 are opened on one side of the long formwork 2. One end of the self-locking bolt 32 is threadedly connected in the connecting hole 21. The side plate 31 can support and limit the self-locking bolt 32. The bolt end of the self-locking bolt 32 will abut against the outer wall of the side plate 31, and the bolt itself has a certain self-locking effect.

[0025] After the screw end of the self-locking bolt 32 is threadedly connected to the connecting hole 21, the long formwork 2 and the short formwork 3 can be connected, self-locked and fixed. During installation, the self-locking bolt 32 can be quickly rotated using tools such as an electric wrench, which is relatively convenient. After the self-locking bolt 32 is connected to the connecting holes 21 at different positions, the cross-sectional size of the steel formwork will be changed, which is suitable for the manufacture of frame columns 1 with different cross-sectional sizes.

[0026] Reference Figure 2-4A blocking mechanism is provided in the connection hole 21 for blocking concrete flowing toward the connection hole 21 when pouring concrete. The blocking mechanism includes a spring 22 fixedly arranged on the inner side of the connection hole 21, and a cover plate 23 fixedly arranged on one end of the spring 22 for blocking the opening of the connection hole 21. Under the elastic force of the spring 22, one side of the cover plate 23 will be flush with the outer wall of the long template 2, thereby blocking the opening of the connection hole 21.

[0027] Reference Figure 2-4 A fixing ring 24 is fixedly provided on one side of the cover plate 23 close to the spring 22, and a sealing ring 25 for sealing the connection between the cover plate 23 and the long template 2 is fixedly provided on the outer wall of the fixing ring 24. The fixing ring 24 can connect the cover plate 23 and the sealing ring 25, and the sealing ring 25 can seal the connection hole 21, so that the poured concrete will not enter the connection hole 21 under the sealing of the cover plate 23 and the sealing ring 25.

[0028] Reference Figure 2-4 A plurality of groups of air guide holes 26 communicating with the connecting hole 21 are provided on the side of the long template 2 facing away from the frame column 1. The air guide holes 26 can connect the air in the connecting hole 21 with the outside air, thereby preventing the cover plate 23 from being obstructed from continuing to move due to the inability to discharge the air in the cover plate 23 in time when the self-locking bolts 32 squeeze the cover plate 23.

[0029] Reference Figure 2-4 A sleeve hole 35 is provided at the screw end of the self-locking bolt 32, and a ball 36 that cooperates with the cover plate 23 is rotatably provided in the sleeve hole 35 of the self-locking bolt 32. The self-locking bolt 32 can support and limit the ball 36 through the sleeve hole 35. The connection method between the self-locking bolt 32 and the ball 36 is the same as the connection method of the rotating mechanism of the existing ball joint. Through the connection of the ball 36, the wear of the cover plate 23 during the rotation of the self-locking bolt 32 can be reduced, thereby extending the service life of the cover plate 23.

[0030] Reference Figure 1-2 A sealing mechanism is provided between the long formwork 2 and the short formwork 3, and fixing grooves 33 are provided on both sides of the short formwork 3. The sealing mechanism includes a sealing strip 34 fixed in the fixing groove 33 of the short formwork 3 and abutting against the long formwork 2. The short formwork 3 can accommodate and fix the sealing strip 34 through the fixing groove 33. The sealing strip 34 can seal the connection between the long formwork 2 and the short formwork 3, which is beneficial to the forming of the frame column 1 in the steel formwork.

[0031] Reference Figure 1The long formwork 2 and the short formwork 3 are fixedly installed with an adjustable diagonal brace 4 for reinforcing the steel formwork on one side away from the frame column 1. The adjustable diagonal brace 4 can be a diagonal brace rod used for lateral support of the formwork and with adjustable length. Its internal structure and principle have been disclosed and will not be described in detail here. The adjustable diagonal brace 4 can reinforce the long formwork 2 and the short formwork 3, so that the outer sides of the long formwork 2 and the short formwork 3 do not need to use reinforcement hoops, thereby realizing hoop-free construction.

[0032] The implementation principle of the self-locking steel mold of the frame column of the utility model embodiment is:

[0033] When in use, people can first tie the steel bars to form a steel cage, and then assemble the steel formwork outside the steel cage. When assembling, people can screw the self-locking bolts 32 on one side of the side plate 31 into the connecting holes 21 at the corresponding positions in the long formwork 2 according to the cross-sectional size of the frame column 1 to be manufactured, so as to connect, self-lock and fix the long formwork 2 and the short formwork 3. When all the self-locking bolts 32 are tightened, the two long formworks 2 and the two short formworks 3 will form a steel formwork for shaping the frame column 1, and then the steel formwork is reinforced by using the adjustable diagonal brace 4;

[0034] Then people can pour concrete into the steel formwork, and after the concrete solidifies and forms, a frame column 1 will be formed. Then people can remove the steel formwork outside the frame column 1 to be used in the manufacturing process of the frame column 1 of the next cross-sectional size;

[0035] When pouring concrete, due to the elastic force of the spring 22, one side of the cover plate 23 will be flush with the outer wall of the long template 2, thereby blocking the opening of the connecting hole 21. The sealing ring 25 seals the connection between the connecting hole 21 and the cover plate 23, which can prevent the poured concrete from entering the connecting hole 21 and solidifying and becoming inconvenient to clean.

[0036] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
