Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a hinged high and low grade concrete intercepting device. Background Art

[0002] According to the design and specification requirements, at the beam-column joint, when the concrete strength of the column is higher than that of the floor beam and slab, the concrete strength of 50N / mm2 is the first level. If the concrete strength grade of the column is higher than that of the beam and slab by no more than one level, the concrete at the beam-column joint can be poured together with the concrete of the beam and slab. When it exceeds one level, the concrete strength grade of the core area of ​​the beam-column joint is the same as that of the frame column of this floor. During construction, the concrete of the core area of ​​the beam-column joint needs to be poured twice, first pouring the column and then pouring the beam. It is necessary to install a structure on the column side to intercept the column concrete. Due to the dense reinforcement of the beam-column joint, the complex node and the small construction space, it is not convenient to remove the template installation.

[0003] In traditional construction, the construction team uses quick-closed mesh and wire mesh as partitions to distinguish and prevent the mixing of high-grade and low-grade concrete. However, this method has significant limitations. First, although the quick-closed mesh does not need to be disassembled later, it is a one-time investment, expensive, and cannot be reused, which increases the overall construction cost. Secondly, the sealing and strength of the wire mesh are limited. It is easy to break under the side pressure of the concrete, resulting in the mixing of concrete of different grades, which not only increases the construction cost, but also may lead to a decline in the quality of concrete construction, such as difficulties in handling the interface and inconsistent concrete color, which seriously affects the appearance quality of the building and the stability of the overall structure.

[0004] In order to solve these problems, some construction teams have tried to use partition airbags as an alternative. After the steel bars at the beam-column joint are tied, uninflated rubber inflatable airbags are placed according to the gaps between the steel bars. After placement, they are inflated with an air pump. The airbags are inflated to fill the gaps between the beam and steel bars, and the high-strength concrete at the beam-column joint is completely separated from the low-strength concrete at the beam and slab. Then, high-strength concrete at the beam-column joint is poured. Before pouring the low-strength concrete at the beam and slab, the airbags are deflated and shrunk. The airbags are separated from the concrete and can be pulled out and cleaned before use on the next floor or water flow section. Although partition airbags can play an isolating role to a certain extent, they also expose many problems during their application. For example, when multiple airbags are used side by side, they push against each other when they expand, making it difficult to form a stable sealing effect, and they are difficult to fix. In addition, concrete is likely to remain on the surface after the airbags are removed, which is easy to cause damage during cleaning, further increasing the cost and difficulty of cleaning.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] Figure 1 The overall structure of an embodiment of the utility model is shown in FIG. Figure 1 , Figure 2 The overall structure of an embodiment of the utility model is shown in FIG. Figure 2 .like Figure 1 and Figure 2 As shown, according to an embodiment of the utility model, a hinged high-low grade concrete interception device comprises: a fixed structure 1, a hinged interception structure 2, and a fixing device 3;

[0026] One end of the hinged intercepting structure 2 is fixed to the fixed structure 1 through a fixing device 3, and the hinged intercepting structure 2 is rotatably and detachably connected to the fixed structure 1.

[0027] In the present embodiment, a hinged high and low grade concrete interception device includes a fixed structure 1, a hinged interception structure 2, and a fixing device 3; a plurality of hinged interception devices 2 are fixed on the fixed structure 1 at equal intervals by the fixing device 3, and the hinged interception device 2 is rotatably connected to the fixed structure 1. By changing the connection point between the hinged interception device 2 and the fixed structure 1, the state of the hinged interception device 2 can be changed: when high and low grade concrete interception is required, the wide surface of the hinged interception structure 2 is adjusted to face the direction required to intercept; when the high and low grade concrete interception task is completed, the hinged interception structure 2 and the fixed structure 1 can be disassembled, and the hinged interception structure 2 can be cleaned separately.

[0028] The utility model realizes the effective interception and convenient management of high and low grades in concrete construction. The hinged interception structure can be rotatably and detachably connected to the fixed structure through the fixing device. After the task is completed, it can be conveniently disassembled and cleaned separately, which improves construction efficiency and reduces maintenance costs.

[0029] According to an embodiment of the utility model, fixing holes are opened at equal intervals on one side of the fixing structure 1, and the fixing holes are used to fix the fixing device 3. The spacing of the fixing holes is set according to the width of the hinge-type interception device 2, and the hinge-type interception device 2 with wide sides arranged side by side can effectively intercept concrete in the construction state.

[0030] The fixing structure 1 uses a 50mm×80mm×800mm wooden beam; the fixing device 3 uses a bolt with a diameter of 10mm.

[0031] In this embodiment, the fixing structure 1 uses a 50mm×80mm×800mm wooden beam, on which fixing holes are arranged at equal intervals. The inside of the fixing holes has threads matching bolts with a diameter of 10mm. The fixing device 3 using bolts with a diameter of 10mm can be screwed to the fixing holes of the fixing structure 1.

[0032] The utility model adopts standardized wooden beams as the fixing structure and utilizes common bolts with a diameter of 10 mm as the fixing device. By opening equally spaced fixing holes on the wooden beams, simple screw fixing is performed, thereby simplifying the structure and reducing the cost, while ensuring the convenience of construction and the effectiveness of the interception effect.

[0033] Figure 3 This is a front view of a hinged interception structure according to an embodiment of the utility model. Figure 4 This is a side view of a hinged interception structure according to one embodiment of the present invention. Figure 3 and Figure 4 As shown, according to an embodiment of the present utility model, the hinge-type interception structure 2 includes: an adjustment member 21 and an interception hinge 22;

[0034] The adjusting member 21 is disposed at the end of the intercepting hinge 22 , and the direction of the intercepting hinge 22 is changed by adjusting the relative position of the adjusting member 21 and the fixing structure 1 .

[0035] In the present embodiment, the hinge-type intercepting structure 2 includes an adjusting member 21 and an intercepting hinge 22. The adjusting member 21 is welded to at least one end of the intercepting hinge 22. When both ends of the intercepting hinge 22 are fixed to the fixed structure 1 through the adjusting member 21, both ends of the intercepting hinge 22 are provided with adjusting members 21. In the present embodiment, one end thereof is provided with an adjusting member 21 as an example. The direction of the intercepting hinge 22 is changed by adjusting the relative position of the adjusting member 21 and the fixed structure 1. For example, when the adjusting member 21 is cylindrical and passes through the fixed structure 1, the direction of the intercepting hinge 22 can be changed by rotating the adjusting member 21, so that the width direction of the intercepting hinge 22 faces the direction in which concrete interception is required, thereby realizing the interception of high and low grade concrete.

[0036] The hinge-type intercepting structure of the utility model can flexibly adjust the direction of the intercepting hinge through an adjusting component welded at the end of the intercepting hinge, ensuring that the width direction of the intercepting hinge accurately faces the flow direction of concrete that needs to be intercepted, thereby effectively realizing the interception of high and low grade concrete and improving construction efficiency and interception accuracy.

[0037] According to an embodiment of the present utility model, the adjusting member 21 is a cylindrical structure, and the outer wall of the adjusting member 21 is provided with a slide groove 23 that can accommodate the passage of the fixing device 3, and the direction of the intercepting hinge 22 is changed by changing the position of the fixing device 3 on the slide groove 23;

[0038] The width of the slide groove 23 is 11 mm, and the slide groove 23 is L-shaped.

[0039] In this embodiment, the adjusting member 21 is a cylindrical structure, and the outer wall of the adjusting member 21 is provided with a slide groove 23 that can accommodate the passage of the fixing device 3. The width of the slide groove 23 is 11 mm, which can not only ensure the smooth sliding of the fixing device 3 inside the slide groove 23, but also ensure that the fixing device 3 will not be separated from the slide groove 23; the slide groove 23 is L-shaped, and the direction of the interception hinge 22 is changed by changing the position of the fixing device 3 on the slide groove 23; when the direction of the interception hinge 22 needs to be locked, the fixing device 3 is engaged with the end of the slide groove 23 to ensure that the direction of the interception hinge 22 will not change during the concrete interception process.

[0040] The utility model allows the fixing device to slide smoothly in the slide groove to flexibly change the direction of the interception hinge, thereby ensuring the stability of the fixing device in the slide groove; through the specific shape of the L-shaped slide groove, accurate adjustment and locking of the interception hinge direction are achieved, effectively improving the stability of concrete interception.

[0041] According to an implementation mode of the present utility model, the adjusting member 21 is made of a galvanized iron pipe or a galvanized steel pipe with a diameter of 25 mm, and the intercepting hinge 22 is made of a wide flat pipe with a width of 35 mm and a thickness of 13 mm.

[0042] In this embodiment, the adjusting member 21 is a 25 mm galvanized iron pipe or a galvanized steel pipe. The galvanized layer can effectively prevent the corrosion of the iron pipe or the steel pipe and extend its service life. At the same time, the pipe with a diameter of 25 mm, while ensuring sufficient strength, also provides enough space to set the slide groove 23, so that the fixing device 3 can slide smoothly.

[0043] The intercepting hinge 22 adopts a wide flat tube with a width of 35mm and a thickness of 13mm, which not only ensures that the intercepting hinge has sufficient rigidity and strength to withstand the impact force of concrete, but also makes the intercepting hinge have a certain flexibility and can adapt to a certain degree of deformation, so as to better fit the concrete surface that needs to be intercepted.

[0044] Embodiment 2

[0045] like Figure 1-4 As shown, according to an embodiment of the utility model, a hinged high-low grade concrete interception device comprises: a fixed structure 1, a hinged interception structure 2, and a fixing device 3;

[0046] The fixing structure 1 adopts a 50mm×80mm×800mm wooden beam; the hinged intercepting structure 2 includes: an adjusting member 21 of a cylindrical structure, an intercepting hinge 22, and a slide groove 23 arranged on the outer wall of the adjusting member 21 for accommodating the passage of the fixing device 3; the adjusting member 21 adopts a φ25mm galvanized steel pipe, the intercepting hinge 22 adopts a wide flat pipe with a width of 35mm and a thickness of 13mm, the slide groove 23 is L-shaped and has a width of 11mm; the fixing device 3 adopts a bolt with a diameter of 10mm.

[0047] One side of the fixed structure 1 is provided with fixing holes at equal intervals, and the spacing between the fixing holes is 35 to 36 mm. The fixing device 3 is screwed into the fixing hole, and the slide groove 23 is slidably connected to the fixing device 3. When the adjusting member 21 is rotated clockwise, the fixing device 3 enters the L-shaped end of the slide groove 23 along the slide groove 23. After pressing, the position of the fixing device 3 and the slide groove 23 is locked; at this time, the wide surface of the interception hinge 22 is on the same plane as the length direction of the fixed structure 1, facing the concrete interception direction.

[0048] The utility model can be placed between high-grade and low-grade concrete to be isolated, can fill the gap between the steel bars and the protective layer, can effectively isolate high-grade and low-grade concrete, is convenient and reliable, simple to operate, easy to operate on-site, reduces the difficulty of on-site maintenance for workers, solves the common quality problem of color difference in appearance of high-grade and low-grade concrete, reduces later repairs, and improves construction quality; effectively suppresses the over-pouring of high-grade concrete, greatly reduces material waste, enhances the visual quality of concrete, and better controls the problem of high-grade and low-grade concrete stringing.

[0049] Working principle:

[0050] Place the hinged high and low grade concrete intercepting device → pour concrete → pull out the hinged high and low grade concrete intercepting device → clean the hinged high and low grade concrete intercepting device.

[0051] 1. The wall diameter of the partition device is 25mm. The corresponding interceptor is placed according to the beam height (for example, a hinged high-low grade concrete interceptor with a total length of 500mm is placed when the beam height is 500mm). Lubricating oil is applied to the hinged high-low grade concrete interceptor before placement. After placement, rotate the adjusting member 21 clockwise. Driven by the adjusting member 21, the interception hinge 22 rotates with the width facing the direction to be intercepted. Press the adjusting member 21 downward to lock the direction of the hinged interception structure 2 and the fixed structure 1, and the direction of the interception hinge 22 is fixed.

[0052] 2. When pouring concrete, pour high-strength concrete first, and then pour low-strength concrete to avoid low-strength concrete flowing into the high-strength concrete area.

[0053] 3. After pouring the concrete, take out the hinged high and low grade concrete interception device, first lift the adjustment member 21 upward to unlock it, and then rotate the adjustment member 21 counterclockwise to disassemble the hinged interception structure 2 and the fixed structure 1.

[0054] 4. Rinse the locking hinge type interception structure 2 with clean water, and clean and protect the interception device to ensure multiple recycling uses.

[0055] The hinged high and low grade concrete intercepting device of the utility model has significantly improved the efficiency and concrete quality in construction with its excellent design and high-quality material selection. Through the convenient rotation adjustment component, the interception hinge can quickly adjust and lock the direction, effectively avoiding the mixing of high and low grade concrete, and ensuring the precise control of the compressive strength of concrete. The device adopts puncture-resistant and wear-resistant galvanized iron pipes, which not only enhances the structural strength and makes the casting of large frame beams fuller, but also makes the materials easy to manufacture and easy to operate. In addition, its stability and durability are fully guaranteed in repeated use. Compared with traditional inflatable bag interceptors, this device is easier to operate, has a high turnover rate, and is easy to clean, which greatly reduces construction costs and material loss, making it an ideal choice for intercepting concrete of different grades in slab beam construction.
