Description
Technical Field
[0001] The utility model relates to the technical field of formwork support structures for horizontal joints at the bottom of laminated walls, and particularly to a formwork support structure for horizontal joints at the bottom of laminated walls with a support area. Background Technique
[0002] At the present stage, precast double-sided laminated walls are widely used in prefabricated buildings. To ensure the compactness of the cast-in-place concrete at the horizontal joint between the double-sided laminated wall and the floor slab, according to the specification requirements, the horizontal joint should not be less than 50 mm and not more than 70 mm. Since the gap is small, the construction of the formwork support system is relatively difficult. The traditional formwork support system uses a wooden formwork support system, and it is difficult to position the formwork, and it is necessary to use internal positioning support and tie rods in cooperation.
[0003] However, for the existing formwork support structure for horizontal joints at the bottom of laminated walls, a support rod is used in cooperation with a top plate to support the pre-configured "L"-shaped joint formwork. The rear end of the support rod is limited by a buried part to form the entire support surface to fixedly support the formwork. Then, since the lengths of the joint surfaces are different, with the above traditional support scheme, a large number of support parts need to be prepared to cope with the too long horizontal joint, resulting in a certain economic burden and a large amount of material loss. The support equipment is not convenient to flexibly adjust the size of the support area according to the length of the joint surface, making the practicability of the support device weak and not convenient for manual flexible use.
[0004] Therefore, in view of this, research and improvement are carried out on the deficiencies of the existing structure, and a formwork support structure for horizontal joints at the bottom of laminated walls with a support area is proposed. Content of the Utility Model

[0008] Preferably, the adjusting mechanism further includes a driven bevel gear fixedly arranged inside the support plate at the middle part of the surface of the bidirectional screw, and a driving bevel gear is meshed and arranged above the rear side of the surface of the driven bevel gear.
[0009] Preferably, the adjusting mechanism further includes a handwheel rod fixedly installed above the surface of the driving bevel gear, and the upper end of the handwheel rod rotatably penetrates through the support plate.

Specific embodiments
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] As Figure 1 , Figure 2 and Figure 4 shown, a horizontal joint formwork support structure at the bottom of a laminated wall with a support area includes a support plate 1. A lead screw 2 is fixedly installed in the middle of the right side of the surface of the support plate 1. An adjusting cylinder 3 is threadedly connected to the surface of the lead screw 2. An insertion rod 4 is fixedly installed at the right end of the outer surface of the adjusting cylinder 3. An embedded part 5 is arranged on the right side of the insertion rod 4. A perforation 6 is opened above the surface of the embedded part 5. An adjusting mechanism 7 is installed inside the support plate 1. Movable plates 8 are arranged on both the front and rear sides of the support plate 1.
[0024] By adopting the above technical solution, the insertion rod 4 is inserted into the perforation 6 in the embedded part 5 pre-buried in the cast-in-place concrete, forming a rear limiting support point for the entire support device;
[0025] According to the distance between the support plate 1 and the embedded part 5, the adjusting cylinder 3 can be rotated, so that the adjusting cylinder 3 rotates on the surface of the lead screw 2 and is extended by means of screw extrusion until the insertion rod 4 can be inserted into the perforation 6.
[0026] Furthermore, the adjusting mechanism 7 includes a bidirectional screw 701 rotatably and penetratingly installed above the inner surface of the support plate 1. A guiding rod 702 is fixedly and penetratingly installed below the inner surface of the support plate 1. Both ends of the bidirectional screw 701 and the guiding rod 702 penetrate through the movable plate 8. The bidirectional screw 701 is threadedly connected to the movable plate 8, and the guiding rod 702 is slidably connected to the movable plate 8.
[0027] By adopting the above technical solution, the guide rod 702 can limit the two side movable plates 8, so that when the bidirectional screw rod 701 rotates, the movable plates 8 are pushed and moved to expand by the threads.
[0028] Further, the adjusting mechanism 7 further includes a driven bevel gear 703 fixedly arranged inside the support plate 1 at the middle part of the surface of the bidirectional screw rod 701. A driving bevel gear 704 is meshed and arranged above the rear side of the surface of the driven bevel gear 703. The adjusting mechanism 7 further includes a handwheel rod 705 fixedly installed above the surface of the driving bevel gear 704, and the upper end of the handwheel rod 705 rotatably penetrates through the support plate 1.
[0029] By adopting the above technical solution, the handwheel rod 705 rotates by manual force application, and a transmission is formed among the handwheel rod 705, the driving bevel gear 704 and the driven bevel gear 703. The driven bevel gear 703 is fixed to the bidirectional screw rod 701. That is, the rotation of the handwheel rod 705 can drive the bidirectional screw rod 701 to rotate.
[0030] As Figures 2 - 3 shown, a locking mechanism 9 is arranged above the outer surface of the support plate 1. The locking mechanism 9 includes a positioning hole 901 circumferentially opened around the penetrating part of the handwheel rod 705 above the outer surface of the support plate 1. The locking mechanism 9 further includes a plug pin 902 inserted and arranged inside a certain positioning hole 901, and the upper end of the plug pin 902 slidably penetrates through the handwheel rod 705.
[0031] By adopting the above technical solution, the positioning hole 901 limits the lower end of the plug pin 902, and the plug pin 902 penetrates through the handwheel rod 705. That is, when the plug pin 902 is inserted into the positioning hole 901, the handwheel rod 705 cannot rotate.
[0032] Further, the locking mechanism 9 further includes a fixing plate 903 fixedly installed below the surface of the plug pin 902. A spring 904 is fixedly installed on the outer side of the plug pin 902 and sleeved above the surface of the fixing plate 903. The upper end of the spring 904 is fixedly connected to the handwheel rod 705.
[0033] By adopting the above technical solution, the fixing plate 903 avoids the situation that the plug pin 902 is pulled out excessively and falls off, and limits the maximum upward movement distance of the plug pin 902, just moving out of the positioning hole 901;
[0034] The elastic force of the spring 904 makes the plug pin 902 inserted into the positioning hole 901 more stable.
[0035] Working principle: When using the formwork support structure for the horizontal joint at the bottom of the composite wall with a support area, first, the embedded part 5 is pre-embedded in the cast-in-place concrete. Then, the "L"-shaped joint plate is attached to the horizontal joint. Next, the support plate 1 is pushed against the joint plate. According to the position of the insertion rod 4 relative to the embedded part 5, the adjusting cylinder 3 can be rotated, so that the adjusting cylinder 3 rotates on the surface of the lead screw 2 and is extended by means of screw thread extrusion until the insertion rod 4 can be inserted into the perforation 6. The embedded part 5 limits the support plate 1 under the connection of the lead screw 2 and the adjusting cylinder 3, enabling the support plate 1 to effectively and stably support the joint piece. According to the length of the gap, first pull the bolt 902 upward, and then rotate the driving bevel gear 704 by means of the handwheel rod 705, so as to engage the driven bevel gear 703 to rotate, and finally drive the bidirectional screw 701 to rotate. Under the limitation of the guide rod 702, the two side movable plates 8 expand in the opposite direction, thereby increasing the support area of the entire support plate 1. After the support area is adjusted, loosen the bolt 902, and under the elastic force of the spring 904, the bolt 902 is inserted into the positioning hole 901 at the nearest position, thereby locking the entire handwheel rod 705. The elastic force of the spring 904 makes the insertion of the bolt 902 more stable, thereby preventing the secondary rotation of the handwheel rod 705 and making the position adjusted by the entire adjusting mechanism 7 more stable. This is the working principle of the formwork support structure for the horizontal joint at the bottom of the composite wall with a support area.
