Description

Technical Field

[0001] This utility model relates to the technical field of casting molds, and more specifically, to a casting mold support device at an expansion joint. Background Technology

[0002] In modern construction engineering, due to factors such as thermal expansion and contraction and foundation settlement, long buildings are usually equipped with expansion joints to prevent structural damage caused by stress concentration.

[0003] However, the width of expansion joints is often quite narrow, posing a significant challenge to construction. Reinforcing the formwork or molds at expansion joints during building or wall construction is extremely difficult, and conventional reinforcement methods are often ineffective. Because the formwork cannot be securely reinforced, it is prone to displacement and deformation during concrete pouring, leading to inadequate concrete compaction, poor surface smoothness, and even quality defects such as grout leakage and honeycomb pitting, severely impacting the integrity and durability of the building structure.

[0004] Therefore, there is an urgent need to design a mold reinforcement device suitable for narrow expansion joints. It must not only be able to adapt to the construction environment of confined spaces, but also have reliable reinforcement performance, so as to ensure the quality of concrete pouring and ensure the safety and stability of building projects.

Detailed Implementation

[0018] Example The following description, in conjunction with specific embodiments, further illustrates the points, as shown in the appendix. Figure 1 -Appendix Figure 6 As shown, the casting mold support device at the expansion joint in this embodiment includes a wall 11, an expansion joint 12, an inner template 13 located on the side of the wall 11 near the expansion joint 12, an outer template 14 located on the side of the wall 11 away from the expansion joint 12, multiple horizontally arranged square tubes 15 attached to the inner template 13, multiple horizontally arranged connecting plates 16 attached to the outer template 14, and a pair of connecting components 20 respectively located at both ends of the square tubes 15. The multiple square tubes 15 and multiple connecting plates 16 are evenly distributed in the vertical direction, and the connecting components 20 are used to connect the ends of the square tubes 15 and the ends of the connecting plates 16. Specifically, during installation, the square tubes 15 are horizontally inserted into the expansion joint 12 of the wall 11, and the inner template 13 is compressed by the square tubes 15. The connecting plates 16 are attached to the outer template 14, and the outer template 14 is compressed by the connecting plates 16. Then, the square tubes 15 and the connecting plates 16 are connected by the connecting components 20. By using square tubes 15 to support the inner formwork 13, not only is the thickness of the square tubes 15 sufficient to be inserted into the expansion joint 12, but the square tubes 15 themselves also have sufficient strength to provide good support for the inner formwork 13. Furthermore, installation and disassembly are very convenient and efficient.

[0019] In this embodiment, the connecting component 20 includes a screw 21 passing through the connecting plate 16 and the square tube 15, and a first nut 22 and a second nut respectively threaded to both ends of the screw 21. The first nut 22 abuts against the side of the square tube 15 away from the inner template 13, and the second nut abuts against the side of the connecting plate 16 away from the outer template 14. Specifically, the connecting plate 16 and the square tube 15 are connected by a pull-type screw 21, making the connection and disassembly of the connecting plate 16 and the square tube 15 very convenient, and allowing for repeated use.

[0020] In this embodiment, multiple connecting holes 17 are provided at both ends of the square tube 15. The screw 21 passes through the connecting holes 17, and the multiple connecting holes 17 are distributed along the length of the square tube 15. Specifically, by providing multiple connecting holes 17, the screw 21 can be inserted into the appropriate connecting hole 17 according to the width of the inner template 13, the outer template 14, and the expansion joint 12, so that the screw 21 is as close as possible to the wall 11 but does not contact the wall 11, and the opening of connecting holes 17 on the square tube 15 does not affect the strength of the square tube 15 itself.

[0021] In this embodiment, the connecting hole 17 is elongated, and its length is parallel to the length of the square tube 15. Specifically, setting the connecting hole 17 to be elongated allows for better adjustment of the position of the screw 21. Even if the hole on the connecting plate 16 is not perfectly aligned with the connecting hole 17 on the square tube 15, the position of the screw 21 in the connecting hole 17 can be finely adjusted without moving the square tube 15, thus preventing the screw 21 from bending. Furthermore, there is no connection between the connecting holes 17, which better ensures the structural strength of the square tube 15.

[0022] In this embodiment, a U-shaped pad 23 is provided on the side of the square tube 15 away from the inner template 13; the pad 23 is attached to the outer wall of the square tube 15, the screw 21 passes through the pad 23, and the first nut 22 abuts against the side of the pad 23 away from the square tube 15. Specifically, the pad 23 can prevent the first nut 22 from causing excessive pressure on the connecting hole 17, thus preventing deformation.

[0023] In this embodiment, the connecting component 20 further includes an adjusting component 30 disposed inside the square tube 15. The adjusting component 30 is used to adjust the position of the screw 21 and is disposed at the end of the square tube 15. The adjusting component 30 includes a fixing block 31 fixedly disposed at the end of the square tube 15, an adjusting rod 32 threadedly connected to the fixing block 31, and an adjusting ring 33 rotatably connected to one end of the adjusting rod 32 located inside the square tube 15. The screw 21 passes through the adjusting ring 33. The adjusting ring 33 is elongated, and the width of the inner wall of the adjusting ring 33 is greater than the width of the connecting hole 17, and the length of the inner wall of the adjusting ring 33 is greater than the length of the connecting hole 17. Specifically, the adjusting component 30 is mainly used to adjust the position of the screw 21 in the connecting hole 17. When the screw 21 is long, manually adjusting it may be difficult. Therefore, the adjusting rod 32 can be turned to adjust the position of the adjusting ring 33 so that the adjusting ring 33 coincides with the connecting hole 17 into which the screw 21 needs to be inserted. Then, the screw 21 is inserted into the connecting hole 17 and the adjusting ring 33. The adjusting ring 33 can then be moved by rotating the adjusting rod 32, which in turn moves the screw 21. This operation is more labor-saving and precise.

[0024] In this embodiment, the adjusting rod 32 is located at one end outside the square tube 15 and is connected to a lever 34.

[0025] In this embodiment, the connecting plate 16 has a U-shaped cross-section.

[0026] In summary, the expansion joint casting mold support device of this embodiment involves horizontally inserting the square tube 15 into the expansion joint 12 of the wall 11 during installation. The square tube 15 compresses the inner template 13, while the connecting plate 16 is attached to the outer template 14. The connecting plate 16 then compresses the outer template 14, and the square tube 15 is connected to the connecting plate 16 via the connecting assembly 20. This method of supporting the inner template 13 with the square tube 15 ensures that the tube is thick enough to be inserted into the expansion joint 12, possesses sufficient strength, and effectively supports the inner template 13. Furthermore, installation and disassembly are both convenient and efficient.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
