Description

TECHNICAL FIELD

[0001] The application relates to the technical field of pier column reinforcement, in particular to a pouring and curing integrated device for UHPC (Ultra High Performance Concrete) reinforced circular pier columns. BACKGROUND

[0002] Pier column reinforcement is generally achieved by erecting a formwork outside the pier column to form a pouring space between the formwork and the pier column, pouring UHPC (Ultra High Performance Concrete) into the pouring space, thickening the pier column, and thus reinforcing the pier column. Generally, the bearing capacity of the pier column may be insufficient due to natural erosion, disasters, and accidental impact loads during use, and therefore the pier column needs to be reinforced, or the pier column needs to be reinforced to meet new design requirements in the face of design requirement changes.

[0003] However, the pouring formwork for reinforcing concrete column piers in the prior art generally does not have a curing structure, and the curing effect of the concrete is not good. Moreover, the pouring formwork and the curing structure need to be separately installed and removed, which is relatively low in construction efficiency. CONTENT OF THE UTILITY MODEL

[0032] Embodiment

[0033] The present embodiment provides a pouring and curing integrated device for reinforcing a pier column, referring to Figure 1 The pouring and curing integrated device comprises four formwork assemblies 1, which are divided into two layers, and each layer comprises two formwork assemblies 1 arranged opposite to each other along the center line of the pier column. The formwork assemblies 1 in the same layer are sequentially connected at the head and tail to form a first cavity 2, and surround the pier column, so that a pouring space is formed between the formwork assemblies 1 and the pier column.

[0034] It is to be understood that in other embodiments, the pouring and curing integrated device can also be designed as a single-layer structure, i.e., only two formwork assemblies 1 in the same layer. It can also be designed as a multi-layer structure, i.e., the formwork assemblies 1 are arranged in multiple layers in the vertical direction, and each layer comprises two formwork assemblies 1. The single-layer structure can reinforce the whole plain concrete, and the multi-layer structure can reinforce the plain concrete layer by layer.

[0035] Referring to Figure 2 , the formwork assembly 1 is internally provided with a second cavity 3, referring to Figure 5 and 6 , the second cavity 3 is internally provided with a partition plate 4, which divides the second cavity 3 into a third cavity 5 and a fourth cavity 6, and the third cavity 5 and the fourth cavity 6 are communicated through a pipeline 7. The fourth cavity 6 is communicated with the first cavity 2 through a curing hole 8, the third cavity 5 is connected with a discharge pipeline 10, and the fourth cavity 6 is provided with an inlet pipeline 9. It is to be understood that in Figure 5 and Figure 6 , the partition plate 4 is transparently treated in order to show the structure of the pipeline 7.

[0036] Continuing to refer to Figure 2 , the fourth cavity 6 is internally provided with a water baffle 11, referring to Figure 5As shown, the water baffle 11 is connected with a moving rod 12, which extends outward through the formwork assembly 1, and the water baffle 11 can be moved along the radial direction of the formwork assembly 1 through the moving rod 12. The side of the water baffle 11 away from the moving rod 12 is provided with a water blocking protrusion 13, which is used to block the maintenance hole 8 in a one-to-one correspondence; the bottom of the water baffle 11 is connected with a shielding plate 14, which is used to shield the pipeline 7 by abutting against the partition plate 4. Before pouring, the water baffle 11 is driven by the moving rod 12 to move towards the direction close to the pier column, so that the water blocking protrusion 13 blocks the maintenance hole 8; after pouring, the water baffle 11 is driven by the moving rod 12 to move away from the pier column, so that the water blocking protrusion 13 is separated from the maintenance hole 8, thereby performing maintenance.

[0037] In the maintenance process, it is divided into water maintenance mode and steam maintenance mode. In the water maintenance mode, first, the discharge pipeline 10 is closed, maintenance water is injected into the fourth cavity 6, and then the water baffle 11 is moved to make the maintenance hole 8 conductive, so that the maintenance water passes through the maintenance hole 8 to maintain the poured concrete. After a period of maintenance, the water temperature decreases, and part of the water can be discharged through the discharge pipeline 10 and part of the maintenance water can be added to the fourth cavity 6.

[0038] In the steam maintenance mode, the water baffle 11 is moved to make the maintenance hole 8 conductive, and the discharge pipeline 10 is opened, and steam is injected into the fourth cavity 6 through the inlet pipeline 9, so that the steam forms a flow state from the inlet pipeline 9 to the discharge pipeline 10. During the steam maintenance process, the steam needs to be kept in a flow state; the position of the shielding plate 14 can be adjusted by moving the water baffle 11 to adjust the conductive area of the pipeline 7, so as to control the flow rate of the steam and thus control the maintenance effect.

[0039] The pouring and maintenance integrated device for the UHPC reinforced circular pier column provided by the embodiment can block the maintenance hole 8 by moving the water baffle 11 to make the water blocking protrusion 13 block the maintenance hole 8, thereby blocking the fourth cavity 6 and the first cavity 2, and switching to the pouring state, so as to pour the concrete. The first cavity 2 and the fourth cavity 6 are conductive by moving the water baffle 11 to make the water blocking protrusion 13 separate from the maintenance hole 8, so that the maintenance water or steam can enter the first cavity 2 through the maintenance hole 8 to maintain the concrete. And the shielding area of the pipeline 7 by the shielding plate 14 can be changed by moving the water baffle 11, so as to adjust the cross section of the pipeline 7, adjust the flow rate of the steam, and control the maintenance effect. The pouring formwork and the maintenance structure are integrated into an integrated structure, which can install the pouring formwork and the maintenance structure at one time, improve the construction efficiency and the maintenance effect.

[0040] It should be noted that in the present embodiment, two pieces of the water baffle 11 can be arranged in one formwork assembly 1, and the two pieces of the water baffle 11 are in a split structure and are controlled to move by the moving rod 12 respectively. In other embodiments, three or more pieces of the water baffle 11 can also be arranged.

Figure 3 Specifically, one end of the moving rod 12 is rotationally connected with the water baffle 11, and the other end is threadedly connected with the outer form 16. By rotating the moving rod 12, the moving rod 12 and the outer form 16 can be driven to move relative to each other, thereby driving the water baffle 11 to move, changing the position of the water baffle 11, and realizing the switching between the pouring and maintenance states.

[0042] Specifically, there are various rotationally connecting modes between the moving rod 12 and the water baffle 11. One of the connecting modes can be referred to FIG. 2. A through hole 20 is arranged on the water baffle 11, so that the moving rod 12 passes through the water baffle 11, and a first nut 19 and a second nut 27 are respectively connected on the moving rod 12, so that the first nut 19 and the second nut 27 are respectively located on both sides of the water baffle 11 and abut against the water baffle 11. This mode has simple structure and low cost.

[0043] Figure 8 Another mode can also adopt a bearing to connect the moving rod 12 and the water baffle 11. This mode has relatively more precise structure and stronger accuracy in adjusting the position of the water baffle 11.

[0044] Specifically, referring to FIG. 3, the two formwork assemblies 1 at the same layer are connected by a latch rod 21 and a locking screw 22. The latch rod 21 is connected on one side plate of the formwork assembly 1, and a latch hole 23 is arranged on the other side plate. The latch rod 21 is inserted into the latch hole 23. One end of the outer form 16 near the latch hole 23 is provided with a locking hole 24, which is in communication with the latch hole 23, and the locking screw 22 is arranged in the locking hole 24 and connected with the latch rod 21. When assembling the two formwork assemblies 1 at the same layer, the latch rod 21 is inserted into the latch hole 23, and the locking screw 22 is inserted into the locking hole 24 and connected with the latch rod 21, so as to realize the relative fixation of the two formwork assemblies 1. The connection between the locking screw 22 and the latch rod 21 can be threadedly connected or buckled.

[0045] Specifically, continuing to refer to FIG. 3, the two formwork assemblies 1 at the same layer are connected by a latch rod 21 and a locking screw 22. The latch rod 21 is connected on one side plate of the formwork assembly 1, and a latch hole 23 is arranged on the other side plate. The latch rod 21 is inserted into the latch hole 23. One end of the outer form 16 near the latch hole 23 is provided with a locking hole 24, which is in communication with the latch hole 23, and the locking screw 22 is arranged in the locking hole 24 and connected with the latch rod 21. When assembling the two formwork assemblies 1 at the same layer, the latch rod 21 is inserted into the latch hole 23, and the locking screw 22 is inserted into the locking hole 24 and connected with the latch rod 21, so as to realize the relative fixation of the two formwork assemblies 1. The connection between the locking screw 22 and the latch rod 21 can be threadedly connected or buckled. Figure 4

[0046] Figure 1 ​​​As shown, the template assembly 1 further comprises a cover plate 25 arranged on the top of the second cavity 3. The cover plate 25 can prevent sundries from entering the fourth cavity 6, thereby avoiding the blockage of the maintenance hole 8 and the pipe 7.

[0047] Specifically, at least two circles of pipes 7 are arranged between the third cavity 5 and the fourth cavity 6, and each circle of pipes 7 is arranged along the radial direction of the template assembly 1 in sequence. By adjusting the position of the water baffle 11, the number of pipes 7 that are open can be adjusted, thereby controlling the flow of the maintenance steam.

[0048] Specifically, the exhaust pipe 9 is connected to an external water source or gas source, and the exhaust pipe 9 and the exhaust pipe 10 are respectively provided with valves.

[0049] Specifically, the template assembly 1 between the upper and lower layers can be assembled by using a convex structure 26 arranged below the bottom die 18.
