Description

Technical Field

[0001] This utility model belongs to the field of building pouring construction technology, specifically relating to a large-volume concrete pouring construction template. Background Technology

[0002] Concrete pouring, short for concrete pouring, refers to the construction process of pouring, leveling, and compacting the mixed concrete into a formwork. Pouring requires continuity and uniformity, and must prevent segregation of the concrete. Leveling involves using manual or mechanical methods to evenly spread and fill the entire poured surface with concrete. Compaction, also known as vibration, can be done manually or mechanically, with mechanical vibration being more commonly used in water conservancy projects.

[0003] Construction formwork is used in the pouring process. Traditional construction formwork is a board-shaped structure, which has low applicability for large-volume concrete pouring construction, is not convenient for quick assembly and use, and lacks effective support and stabilization mechanisms during use. Therefore, we propose a construction formwork for large-volume concrete pouring. Utility Model Content

[0004] The purpose of this utility model is to provide a large-volume concrete pouring construction template to solve the problems mentioned in the background art, which are that the traditional construction template is a board-shaped structure, which has low applicability for some large-volume concrete pouring construction, is not convenient for quick assembly and use, and lacks an effective support and stabilization mechanism during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a large-volume concrete pouring formwork, comprising several pouring formworks, with a connecting seat provided between two adjacent pouring formworks in the horizontal direction. Two connecting locking rods are slidably installed on the connecting seat, and the ends of the two connecting locking rods are fixedly installed with the same connecting operating plate. Connecting locking grooves are provided at both ends of the side of each pouring formwork, and the connecting locking rods cooperate with the connecting locking grooves. A supporting bottom shell is fixedly installed on the side of the pouring formwork at the lowest position, and a threaded rod is rotatably installed inside the supporting bottom shell, with one end of the threaded rod extending out... A knob is fixedly installed on the supporting base shell. A threaded plate is threaded on the outer surface of the threaded rod. A connecting plate is fixedly installed at both ends of the threaded plate. A hinge seat is fixedly installed at the end of the connecting plate. A hinge arm one is hingedly installed on the hinge seat. An extension arm is slidably provided at the end of the hinge arm one away from the hinge seat. A hinge arm two is slidably provided on the outer surface of the end of the extension arm away from the hinge arm one. A mounting seat is hingedly installed at the end of the hinge arm two. Several mounting bolts are threadedly installed on the mounting seat. Several mounting thread grooves are opened on the side of the casting template. The mounting bolts are used in conjunction with the mounting thread grooves.

[0006] The above scheme uses a connecting seat to connect and lock two adjacent pouring templates in the horizontal direction. Alignment guide rods and guide grooves are used to align and assemble two adjacent pouring templates in the vertical direction, allowing multiple pouring templates to be freely assembled. This is suitable for large-volume, large-area concrete pouring construction scenarios. The operation and assembly structure is simple and convenient. A supporting base is used in conjunction with a hinged seat, hinged arm one, extension arm, hinged arm two, and mounting base. The triangle formed between the supporting base, hinged arm one, extension arm, hinged arm two, and the pouring template provides support, effectively improving the overall stability of the pouring template. Furthermore, the tilt angles of hinged arm one, extension arm, and hinged arm two can be selectively adjusted according to the usage height of the pouring template, further enhancing the support effect.

[0007] In a preferred embodiment, a plurality of alignment guide rods are fixedly installed on the upper surface of the casting template, and a plurality of alignment guide grooves are provided on the lower surface of the casting template. The alignment guide rods on the casting template at the lower position are inserted into the alignment guide grooves on the casting template at the upper position.

[0008] By using the above method, the alignment guide rod is inserted into the alignment guide groove to realize the alignment and assembly of the casting template at the upper and lower positions. The assembly has good stability and is not easy to shake.

[0009] In a preferred embodiment, the upper and lower surfaces and the left and right surfaces of the casting template are provided with sealing grooves, and sealing strips are embedded in the sealing grooves. The sealing strips on two adjacent casting templates are arranged in close contact with each other.

[0010] By using the above solution, the sealing groove can be used in conjunction with the sealing strip to ensure a good seal at the joint of adjacent pouring formwork after assembly, thus preventing concrete from overflowing.

[0011] In a preferred embodiment, a cavity is provided on the connecting seat opposite the connecting locking rod, and a spring is fixedly installed in the cavity. A limit ring is fixedly installed on the outer surface of the connecting locking rod, and the limit ring is located inside the cavity and fixedly connected to the spring.

[0012] By adopting the above solution, the setting of the limiting ring can prevent the connecting lock rod from slipping off the connecting seat, thus playing a limiting role. The elastic force of the spring can drive the connecting lock rod to move quickly and insert into the connecting lock groove, improving the convenience of locking operation.

[0013] In one preferred embodiment, a plurality of limiting rods are fixedly installed on the inner wall of the supporting base shell, and the threaded plate is slidably installed on the outer surface of the plurality of limiting rods.

[0014] By adopting the above scheme, the setting of the limit rod can support and guide the movement of the threaded plate, improve the smoothness of movement, and avoid swaying.

[0015] In a preferred embodiment, limit sliders are fixedly installed on the inner walls of both the first hinge arm and the second hinge arm, and a limit groove is formed on the side of the extension arm, with the limit slider slidably installed on the inner wall of the limit groove.

[0016] By adopting the above scheme, using the limiting slider in conjunction with the limiting groove, it is possible to ensure stable sliding between the extension arm and the first and second articulated arms, and to prevent separation between the extension arm and the first and second articulated arms.

[0017] In a preferred embodiment, two trapezoidal slide bars are fixedly installed on the side of the connecting seat, and trapezoidal grooves are provided at both ends of the side of the casting template. The trapezoidal slide bars and trapezoidal grooves are used in conjunction.

[0018] By adopting the above scheme, trapezoidal sliders are slidably inserted into trapezoidal grooves to avoid separation between the connecting seat and the casting template, thereby improving the stability of the assembly and locking effect.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This large-volume concrete pouring formwork connects and locks two adjacent pouring formworks in the horizontal direction by setting a connecting seat, and uses alignment guide rods and alignment guide grooves to align and assemble two adjacent pouring formworks in the vertical direction, so that multiple pouring formworks can be freely assembled. It is suitable for use in large-volume and large-area concrete pouring construction scenarios, and the operation and assembly structure is simple and convenient to use.

[0021] This large-volume concrete pouring formwork is designed with a supporting base shell, hinged seat, hinged arm one, extension arm, hinged arm two, and mounting base. It utilizes the triangle formed by the supporting base shell, hinged arm one, extension arm, hinged arm two, and the pouring formwork for support, effectively improving the overall stability of the pouring formwork. Furthermore, the tilt angle of hinged arm one, extension arm, and hinged arm two can be selectively adjusted according to the usage height of the pouring formwork, further enhancing the support effect.

[0031] Please see Figures 1-8 This utility model provides a large-volume concrete pouring formwork, including several pouring formworks 1. A connecting seat 2 is provided between two adjacent pouring formworks 1 in the horizontal direction. Two connecting locking rods 3 are slidably installed on the connecting seat 2. A common connecting operating plate 4 is fixedly installed at the ends of the two connecting locking rods 3. Connecting locking grooves 23 are provided at both ends of the side of the pouring formwork 1. The connecting locking rods 3 cooperate with the connecting locking grooves 23. A supporting base shell 5 is fixedly installed on the side of the lowest pouring formwork 1. A threaded rod 6 is rotatably installed inside the supporting base shell 5. One end of the threaded rod 6 extends out of the supporting base shell 5 and is fixedly installed with a knob. A threaded plate 7 is threaded onto the outer surface of the threaded rod 6. A connecting plate 8 is fixedly installed at both ends of the threaded plate 7. A hinge seat 9 is fixedly installed at the end of the connecting plate 8. A hinge arm 10 is hingedly installed on the hinge seat 9. An extension arm 11 is slidably provided at the end of the hinge arm 10 away from the hinge seat 9. A second hinge arm 12 is slidably provided on the outer surface of the end of the extension arm 11 away from the first hinge arm 10.

Several mounting thread grooves 24 are opened on the side of the casting template 1. The mounting bolts 14 are used in conjunction with the mounting thread grooves 24.

[0032] By setting a connecting seat 2 to connect and lock two adjacent pouring templates 1 in the horizontal direction, and by using the alignment guide rod 15 and the alignment guide groove 22 to align and assemble two adjacent pouring templates 1 in the vertical direction, multiple pouring templates 1 can be freely assembled. This is suitable for use in large-volume and large-area concrete pouring construction scenarios. The operation and assembly structure is simple and easy to use. By setting a supporting bottom shell 5 in conjunction with the hinge seat 9, hinge arm one 10, extension arm 11 and hinge arm two 12 and the mounting seat 13, the support is provided by the triangle formed between the supporting bottom shell 5 and the hinge arm one 10, extension arm 11 and hinge arm two 12 and the pouring template 1, which effectively improves the overall stability of the pouring template 1. The tilt angle of the hinge arm one 10, extension arm 11 and hinge arm two 12 can be selectively adjusted according to the height of the pouring template 1 to further improve the support effect.

[0033] Several alignment guide rods 15 are fixedly installed on the upper surface of the casting template 1, and several alignment guide grooves 22 are opened on the lower surface of the casting template 1. The alignment guide rods 15 on the lower position of the casting template 1 are inserted into the alignment guide grooves 22 on the upper position of the casting template 1.

[0035] A cavity is provided on the connecting seat 2 directly opposite the connecting locking rod 3, and a spring 19 is fixedly installed in the cavity. A limit ring 18 is fixedly installed on the outer surface of the connecting locking rod 3. The limit ring 18 is located inside the cavity and is fixedly connected to the spring 19. The limit ring 18 can prevent the connecting locking rod 3 from sliding off the connecting seat 2, thus providing a limiting effect. The elastic force of the spring 19 can drive the connecting locking rod 3 to move quickly and insert into the connecting lock groove 23, improving the convenience of locking operation.

[0036] Several limiting rods 20 are fixedly installed on the inner wall of the supporting base shell 5. The threaded plate 7 is slidably installed on the outer surface of the several limiting rods 20. The setting of the limiting rods 20 can support and guide the movement of the threaded plate 7, improve the stability of the movement, and avoid the phenomenon of shaking.

A limiting groove is opened on the side of the extension arm 11. The limiting sliders 21 are slidably installed on the inner wall of the limiting groove. By using the limiting sliders 21 in conjunction with the limiting groove, it is possible to ensure stable sliding between the extension arm 11 and the first articulated arm 10 and the second articulated arm 12, and to prevent separation between the extension arm 11 and the first articulated arm 10 and the second articulated arm 12.

[0038] Two trapezoidal slide bars 17 are fixedly installed on the side of the connecting seat 2. Trapezoidal grooves are provided at both ends of the side of the casting template 1. The trapezoidal slide bars 17 are used in conjunction with the trapezoidal grooves. The trapezoidal slide bars 17 are slidably inserted into the trapezoidal grooves to prevent separation between the connecting seat 2 and the casting template 1, thereby improving the stability of the assembly and locking effect.

[0039] In use, first assemble the horizontal casting template 1. The connecting seat 2 is inserted into the trapezoidal grooves on two adjacent horizontal casting templates 1 via the trapezoidal slide bar 17. Simultaneously, pull the connecting operating plate 4 to displace the connecting locking rod 3 from the casting template 1, causing elastic deformation. When the trapezoidal slide bar 17 is fully inserted into the trapezoidal groove, release the connecting operating plate 4. The spring force of the spring 19 drives the connecting locking rod 3 to reset and insert into the connecting locking groove 23. Then, assemble the remaining horizontal casting templates 1 sequentially. After assembly, use the alignment guide rod 15 and... The alignment guide groove 22 is used to align and insert the vertical casting template 1. After insertion, the mounting seat 13 is installed in the mounting thread groove 24 on the uppermost casting template 1 using mounting bolts 14 according to the height of the entire assembled casting template 1. Then, the horizontal position of the hinge seat 9 is adjusted. During adjustment, the knob is turned to drive the threaded rod 6 to rotate, which in turn drives the threaded plate 7 to move the connecting plate 8, which in turn drives the hinge seat 9 to move. The hinge arm 10, extension arm 11 and hinge arm 2 12 are used in combination to achieve overall support and stability of the casting template 1.
