Description

Technical Field

[0001] The utility model relates to the technical field of building formwork support structures, and specifically relates to a combined support device for concrete pouring in a single-side formwork project. Background Technique

[0002] Single-side formwork is a common wall pouring construction process. The wall is poured through a formwork, and the formwork is only supported on one side. It is often used for pouring groundwater walls, sewage tank walls, etc.

[0003] At the current pouring construction site, single-side formwork mostly uses a combination of support steel structure members to support the formwork. The steel frame is divided into upper and lower layers and combined into a large right-angled triangle support. Each large support is attached to the side of the formwork. In actual use, there are some functional deficiencies and there is room for improvement. For example, when the ground in the construction area is uneven, and the number of groups of the support itself is large, the grouped supports support each other, and it is easy for some of the supports at the bottom to be suspended between the ground, which will increase the load on other supports, and the external support force of the formwork is unevenly distributed. At present, the conventional solution is to adjust by hand-tightening screw rods so that the screw rods are pressed against the ground to form a support, but the support strength is not easy to grasp, and it depends to a large extent on the feel of the adjusting master, and it does not have the function of automatically adjusting the bottom support.

[0004] Now, a new combined support device for concrete pouring in a single-side formwork project is proposed to solve the above problems. Content of the Utility Model

At the bottom of the first horizontal support, a support assembly capable of automatically adjusting the supporting force is provided.

[0007] The support assembly includes a high-strength steel pipe, which is fixedly connected to the left side of the bottom end of the first horizontal support. A push rod is inserted into the high-strength steel pipe from bottom to top. At the bottom end of the push rod, a support foot is fixedly connected.

Multiple connecting bolts are arranged inside the inner sliding groove. A locking nut is sleeved outside the connecting bolt. A non-slip pad is arranged on the right side of the locking nut.

[0012] Preferably, the upper and lower ends of the steel long groove are respectively in contact with the right-angle limit blocks, and the right-angle limit blocks and the steel long groove are not connected.

[0013] Preferably, the top end of the second inclined support frame is fixedly connected with a top support frame, the top of the top support frame is fixedly connected with a top rain shield, and two groups of inclined support skeletons are installed between the bottom end of the top support frame and the left side of the second inclined support frame.

The support feet at the bottom of the push rod and the bottom of the first vertical bracket jointly support the ground. Connect the power supplies of the pressure sensor and the large-thrust electric cylinder. The pressure sensor senses the pressure from the push rod. When the pressure is low, it means that the bottom is suspended. The large-thrust electric cylinder will start and extend downward, pushing the push rod downward. The push rod displaces downward along the high-strength steel pipe, so that the support feet are pressed against the ground until the pressure sensed by the pressure sensor reaches the preset threshold value. The large-thrust electric cylinder will stop extending and maintain the current length. Just disconnect the power supply later, realizing the function of automatically adjusting the bottom support.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to 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.

[0025] Embodiment 1: Please refer to Figures 1-4, a combined support device for concrete pouring in a single-sided formwork project, comprising multiple groups of first vertical supports 1.

At the top end on the left side of the first vertical support 1, a second horizontal support 9 is horizontally welded. Between the top end of the first horizontal support 2 and the bottom end of the second horizontal support 9, a first inclined support frame 8 is welded. On the left side of the top of the second horizontal support 9, an internally threaded fixed pipe 10 is fixedly connected. Above the second horizontal support 9, a third horizontal support 14 is arranged. On the right side of the top of the second horizontal support 9, a concave seat 11 is fixedly connected. On the right side of the third horizontal support 14 at the bottom, a convex block 13 is fixedly connected. Five fixing bolts 12 are inserted into the right side of the concave seat 11. On the left side of the top of the third horizontal support 14, an externally threaded connecting rod 15 is inserted. On the right side of the top of the third horizontal support 14, a second vertical support 17 is welded. On the left side of the second vertical support 17, a second inclined support frame 16 is fixedly connected. At the bottom end of the first horizontal support 2, there is a support assembly that can automatically adjust the supporting force;

[0026] Please refer to Figures 1-4 , a combined support device for concrete pouring in a single-sided formwork project further includes a support assembly. The support assembly includes a high-strength steel pipe 3. The high-strength steel pipe 3 is fixedly connected to the left side of the bottom end of the first horizontal support 2. Inside the high-strength steel pipe 3, a push rod 4 is inserted from bottom to top. At the bottom end of the push rod 4, a support foot 5 is fixedly connected. On the left side of the top of the first horizontal support 2, a large-thrust electric cylinder 7 is installed. At the bottom end of the large-thrust electric cylinder 7, a pressure sensor 6 is installed;

[0027] The top end of the high-strength steel pipe 3 is flush with the top end of the first horizontal support 2. The vertical centerlines of the high-strength steel pipe 3, the push rod 4, and the support foot 5 coincide. The outer diameter of the push rod 4 is adapted to the inner diameter of the high-strength steel pipe 3. The push rod 4 can displace up and down inside the high-strength steel pipe 3. The bottom end of the pressure sensor 6 is flush with the top end of the push rod 4. The pressure sensor 6 and the large-thrust electric cylinder 7 are electrically connected, and the bottom support force can be adjusted to make the overall support force balanced;

[0028] Specifically, as shown in Figure 1 and Figure 2 , the support foot 5 at the bottom of the push rod 4 and the bottom of the first vertical support 1 jointly support the ground. Connect the power supplies of the pressure sensor 6 and the large-thrust electric cylinder 7. The pressure sensor 6 senses the pressure from the push rod 4. When the pressure is low, it indicates that the bottom is suspended. The large-thrust electric cylinder 7 is activated and extends downward, pushing the push rod 4 downward. The push rod 4 displaces downward along the high-strength steel pipe 3, making the support foot 5 press tightly against the ground until the pressure sensed by the pressure sensor 6 reaches the preset threshold. The large-thrust electric cylinder 7 stops extending and maintains the current length. Just disconnect the power supply later.

[0029] Embodiment 2: Six groups of right-angle limit blocks 18 are respectively welded to the right sides of the first vertical support 1 and the second vertical support 17. Three groups of formwork connecting plates 20 are respectively arranged on the right sides of the first vertical support 1 and the second vertical support 17. A steel long groove 19 is fixedly connected to the left side of the formwork connecting plate 20. An inner chute 21 is arranged inside the steel long groove 19. A plurality of connecting bolts 22 are arranged inside the inner chute 21. An anti-loosening nut 23 is sleeved outside the connecting bolt 22. An anti-slip pad 24 is arranged on the right side of the anti-loosening nut 23. The upper and lower ends of the steel long groove 19 are respectively in contact with the right-angle limit blocks 18, and the right-angle limit blocks 18 and the steel long groove 19 are not connected, which is convenient for docking with the formwork.

[0030] Specifically, as Figure 1 and Figure 3 shown, the right-angle limit blocks 18 on the back of the first vertical support 1 and the second vertical support 17 are just in contact with the upper and lower sides of the steel long groove 19. The formwork connecting plate 20 and the concrete formwork are connected by bolts. The connecting bolts 22 in the inner chute 21 pass through the first vertical support 1 and the second vertical support 17. The anti-slip pad 24 and the anti-loosening nut 23 are successively sleeved on the connecting bolt 22. Tightening the anti-loosening nut 23 completes the docking with the formwork.

[0031] Embodiment 3: The top of the second inclined support frame 16 is fixedly connected with a top support frame 26. The top of the top support frame 26 is fixedly connected with a top rain shield 27. Two groups of inclined support skeletons 25 are installed between the bottom end of the top support frame 26 and the left side of the second inclined support frame 16. The left side of the top rain shield 27 is in the same vertical plane as the left side of the first horizontal support 2. The right side of the top rain shield 27 is in contact with the left side of the second vertical support 17, which can shield rain and snow and protect the steel frame below.

[0032] Specifically, as Figure 1 and Figure 4 shown, the top rain shield 27 at the top of the top support frame 26 can block rain and snow, protect the support below, and reduce the probability of it getting damp and rusty. The inclined support skeletons 25 provide further support for the top support frame 26.

[0033] Working principle: When the utility model is in use, first, the first vertical support 1, the first horizontal support 2, the first inclined support frame 8, and the second horizontal support 9 form the bottom support frame, and the third horizontal support 14, the second inclined support frame 16, and the second vertical support 17 form the high part support frame. The two support frames are butt-jointed through the concave seat 11, the fixing bolt 12, and the convex block 13. Six groups of steel long grooves 19 are fixed on the supporting surface of the formwork. The support frame is connected to the steel long grooves 19 to support the formwork. The support feet 5 at the bottom of the push rod 4 and the bottom of the first vertical support 1 jointly support the ground. Connect the power supplies of the pressure sensor 6 and the large-thrust electric cylinder 7. The pressure sensor 6 senses the pressure from the push rod 4. When the pressure is too low, it indicates that the bottom is suspended. The large-thrust electric cylinder 7 is immediately started and extends downward to push the push rod 4 downward. The push rod 4 displaces downward along the high-strength steel pipe 3, so that the support feet 5 are pressed against the ground until the pressure sensed by the pressure sensor 6 reaches the preset threshold value. The large-thrust electric cylinder 7 immediately stops extending and maintains the current length. Just disconnect the power supply later. Press the back surfaces of the first vertical support 1 and the second vertical support 17 against the steel long grooves 19. The right-angle limit block 18 just adheres to the upper and lower sides of the steel long grooves 19. The formwork connecting plate 20 and the concrete formwork are connected by bolts. The connecting bolts 22 in the inner chute 21 pass through the first vertical support 1 and the second vertical support 17. The anti-slip pads 24 and the anti-loosening nuts 23 are sequentially sleeved on the connecting bolts 22. Tightening the anti-loosening nuts 23 completes the docking with the formwork. When pouring in the open air such as a sewage tank, rain protection treatment can be carried out on the top of the second inclined support frame 16. Fix the top support frame 26. The top rain shield 27 on the top of the top support frame 26 can block rain and snow, protect the support frame below, and reduce the probability of its being affected by moisture and rusting. The inclined support skeleton 25 further supports the top support frame 26.
