Description

Technical Field

[0002] In some project structures, there are many door openings in the core tube shear wall. If the wooden formwork of the structural door opening adopts the traditional wooden support method, it will be affected by the rigidity and stability of the formwork and internal support system. During the concrete pouring process, it is easy to have defects such as expansion, deformation, and displacement that affect the quality and appearance of the concrete. Therefore, formwork support parts are needed;

[0003] For example, a cast-in-place lintel formwork support member with a publication (announcement) number of CN212027131 U includes a first support member, the first support member includes a pair of clamping plates arranged in parallel, the pair of clamping plates are connected by a connecting plate; an upper support rod parallel to the connecting plate and used to support the cast-in-place lintel formwork is provided near the first end of the clamping plate, and a lower support rod parallel to the connecting plate and used to abut against the door opening wall to achieve support is provided near the second end of the clamping plate;

[0004] Based on the above, it can be seen that the following technical problems exist in the prior art: although the above-mentioned prior art can support the cast-in-place lintel formwork during use, after adjusting the spacing, the adjustment knob may slip during subsequent use, resulting in the entire support structure being unstable. For this reason, we propose a formwork support. Utility Model Content

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] Example 1

[0026] Reference Figure 1-3 A formwork support component includes two vertical support plates 3 fixed to one side of a door opening wall 1 by screws, and two supporting top plates 4 attached to the bottom of a lintel formwork 2, the vertical support plates 3 are fixed to the supporting top plates 4, the lintel formwork 2 is placed on the top of the door opening wall 1, and an extending support mechanism is installed on the inner side of the two supporting top plates 4, which is used to adjust the distance between the two supporting top plates 4.

[0027] The extended support mechanism includes a matching groove 5, a connecting rod 6 and a threaded rod 7. Two matching grooves 5 are provided at one end of the two supporting top plates 4 close to each other. A connecting rod 6 is slidably connected to the inner side of the two matching grooves 5 on the same side. The bottom of the supporting top plate 4 and the position corresponding to the matching groove 5 are threadedly connected with the threaded rod 7. The top of the threaded rod 7 passes through the matching groove 5 and fits tightly with the connecting rod 6. The end of the threaded rod 7 is provided with an anti-slip texture, and the outer side of the connecting rod 6 is provided with a small groove to increase the friction between the threaded rod 7 and the connecting rod 6.

[0028] A support arm 18 is fixed to one side of the vertical support plate 3, and one end of the support arm 18 is fixed to the supporting top plate 4. Through the setting of the support arm 18, the supporting top plate 4 can be supported to prevent the end of the supporting top plate 4 from being deformed.

[0029] Example 2

[0030] Embodiment 1 is further optimized, specifically, as Figure 4 As shown, a limiting mechanism is assembled between the supporting top plate 4 and the threaded rod 7 , and the limiting mechanism is used to limit the rotation of the threaded rod 7 .

[0031] The limiting mechanism includes a force-applying member and a docking member. The middle part of the bottom of the supporting top plate 4 is rotatably connected with a rotating rod 8. The outer side of the rotating rod 8 is equipped with a force-applying member, and the inner side of the force-applying member is equipped with a docking member.

[0032] The force-applying member includes a force-applying double-headed plate 9, a transmission rod 10, a movable column 11, a fixed column 12 and a connecting tube 13. The outer side of the rotating rod 8 is fixed with a force-applying double-headed plate 9. Both ends of the force-applying double-headed plate 9 are rotatably connected to the transmission rod 10 through pins. One end of the transmission rod 10 is rotatably connected to the movable column 11 through pins. The outer side of the movable column 11 is slidably connected to the connecting tube 13. The top of the connecting tube 13 is fixed with a fixed column 12, and the fixed column 12 is fixed to the supporting top plate 4. When the rotating rod 8 is rotated, the rotating rod 8 drives the force-applying double-headed plate 9 to rotate, and then the movable column 11 can pull the limiting ring 14 to move along the inner side of the connecting tube 13, squeeze and contract the reset spring 15, and then separate the limiting tooth plate 16 from the auxiliary gear 17.

[0033] The docking parts include a limit ring 14, a return spring 15, a limit tooth plate 16 and an auxiliary gear 17. The limit ring 14 is fixed to the outer side of the movable column 11 and located on the inner side of the connecting tube 13. The return spring 15 is fixed to one side of the limit ring 14. The return spring 15 is sleeved on the outer side of the movable column 11. A limit tooth plate 16 is fixed to one end of the movable column 11. An auxiliary gear 17 corresponding to the position of the limit tooth plate 16 is fixed to the outer side of the threaded rod 7. The auxiliary gear 17 is meshed and connected with the limit tooth plate 16. It can be understood that the height of the limit tooth plate 16 is greater than the height of the auxiliary gear 17, so that after the threaded rod 7 drives the auxiliary gear 17 to move one end distance, the limit tooth plate 16 is still able to mesh and connect with the auxiliary gear 17.

[0034] From the above, we can know that:

[0035] The utility model aims at the technical problem that the existing technology can realize the support of the cast-in-place lintel formwork during use, but after adjusting the spacing, the adjustment knob may slip during the later use, resulting in the instability of the entire support structure; the technical solutions of the above embodiments are adopted. At the same time, the implementation process of the above technical solutions is:

[0036] When in use, firstly, the supporting top plate 4 is made to fit in contact with the lintel template 2, and one of the vertical support plates 3 is fixed to the door opening wall 1 by screws, and then the rotating rod 8 is rotated to make the rotating rod 8 drive the force-applying double-headed plate 9 to rotate. Because the force-applying double-headed plate 9 is rotationally connected with the transmission rod 10, and the transmission rod 10 is rotationally connected with the movable column 11, the movable column 11 can pull the limiting ring 14 to move along the inner side of the connecting tube 13, squeeze and contract the reset spring 15, and then separate the limiting tooth plate 16 from the auxiliary gear 17, and then rotate the threaded rod 7 to separate the threaded rod 7 from the connecting rod 6;

[0037] Then pull the other vertical support plate 3 to make it fit and contact with the door opening wall 1, then tighten the threaded rod 7 and loosen the rotating rod 8. At this time, the elastic force generated by the reset spring 15 pushes the limit ring 14 to reset and move until the limit tooth plate 16 and the auxiliary gear 17 are engaged again, thereby forming a rotation limit for the threaded rod 7. Finally, fix the vertical support plate 3 to the door opening wall 1 with screws.

[0038] Through the above configuration, the present application can certainly solve the above technical problems and achieve the following technical effects:

[0039] The utility model extends the structural design of the support mechanism and the limit mechanism, so that the device is easy to adjust the distance between the two support top plates 4, and can also limit the rotation of the threaded rod 7, so that the use effect is stable and the safety of the device is improved.
