Description

Technical Field

[0001] This utility model relates to the field of concrete construction technology for building structures, and in particular to an integrated device for secondary structure pouring and vibration. Background Technology

[0002] Secondary structure pouring is a crucial component of building construction, primarily involving the concrete construction of non-load-bearing walls (such as structural columns and lintels), partition walls, stairs, and infill walls. In recent years, with advancements in building technology and the improvement of industry standards, secondary structure construction has seen improvements in quality and efficiency. However, some prominent issues remain: 1. Problems such as hollow areas, honeycombing, and pitting caused by unstable formwork support, insufficient vibration, and inadequate curing are quite serious, with honeycombing and pitting rates reaching 15%–20%, making exposed rebar particularly prominent in areas with dense rebar. 2. Improper handling of connection points between the secondary structure and the main structure (such as structural columns and lintels) affects overall seismic performance. Existing secondary structures (such as the top of structural columns) often have loosely poured concrete, becoming channels for rainwater infiltration. Verticality deviations in secondary structures (>8mm) lead to uneven finishing surfaces later. 3. In terms of efficiency, secondary structure construction is mainly manual, with low mechanization. Furthermore, due to design-construction discrepancies, worker errors, or material issues, rework rates are high, leading to extended construction periods, reduced efficiency, and increased costs.

[0003] The structural appearance problems, leakage risks, and insufficient local load-bearing capacity caused by concrete quality defects in secondary structures are mainly due to the following reasons: 1. Secondary structural components (such as structural columns) are usually small in size and tall, making it difficult to insert vibrators to the bottom of the columns, resulting in inadequate compaction of the bottom concrete; 2. The openings in the concrete formwork at the top of the secondary structure are designed in the upper position, or holes are made in the upper concrete formwork to provide locations for concrete pouring pipes. These openings cannot be closed during top pouring, leading to incomplete compaction or damage to the integrity of the top concrete, affecting the overall structural integrity. Therefore, solving the problems of difficult vibration in confined spaces and inadequate compaction of the top concrete is a key issue that needs to be addressed in the pouring of secondary structures. Utility Model Content

[0004] One of the objectives of this utility model is, at least, to provide an integrated device for secondary structure pouring and vibration, which can not only solve the problem of difficult vibration in narrow spaces, but also the problem of insufficient compaction of the top concrete, thereby improving the overall construction quality.

[0011] As a preferred embodiment of this utility model, the fixing component includes a clamping plate, a connecting crossbar, a connecting longitudinal bar, and an adjusting lock. The clamping plate is arranged on the outside of the junction between the shaping component and the secondary structure template.

Therefore, the terms used to describe positional relationships in the accompanying drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances. Example

[0028] This embodiment illustrates the structure of an integrated device for secondary structure casting and vibration, for reference... Figure 1 and Figure 2 Taking a structural column with a square cross-section as an example, this structural column is a masonry structural column. The two sides of the structural column are masonry walls 19 constructed in advance. The secondary structure pouring and vibration integrated device includes a secondary structure template 1, a shaping component 2, a pouring guide pipe 3, and an overflow pipe 4. For ease of understanding, the number of secondary structure template 1 and shaping component 2 is set to two pieces. The front and rear sides of the structural column ( Figure 2A secondary structural template 1 (which may actually be composed of multiple templates) is installed on each of the outer sides (front and back directions). A shaping component 2 is installed on top of the secondary structural template 1. The two secondary structural templates 1 and the two shaping components 2 are positioned between the masonry walls 19 on both sides. Reinforcing steel members 6 are arranged in the secondary structure to be poured. The secondary structure is located between the bottom surface 5 and the top beam 8 of the building structure. The two secondary structural templates 1 and the two shaping components 2... The shaping component 2, bottom surface 5, top beam 8 and masonry walls 19 on both sides of the secondary structure together form a rectangular concrete pouring cavity 9. The shaping component 2 is located on top of the secondary structure template 1. One end of the pouring guide pipe 3 passes through the secondary structure template 1 and extends into the concrete pouring cavity 9, and pours from the bottom up. While pouring, it is vibrated and the pouring guide pipe 3 is lifted upward. One end of the overflow pipe 4 passes through the shaping template (21) of the shaping component 2 and extends into the concrete pouring cavity 9, and the other end leads to the external environment space.

[0029] The secondary structure template 1 uses conventional templates such as wooden templates, steel templates, or aluminum templates. Two secondary structure templates 1 are vertically set on the bottom surface 5, with both ends of the two secondary structure templates 1 extending to the outside of the masonry wall 19 (the width of the two ends of the secondary structure template covering the masonry wall is at least 50mm). The two secondary structure templates 1 and the masonry wall 19 form a cuboid with an opening at the top. The two secondary structure templates 1 are tied and fixed by tie components 7. Multiple tie components 7 are set along the length of the secondary structure template 1. The number of tie components 7 is determined according to the length and cross-sectional area (the amount of concrete poured) of the secondary structure. The tie components 7 are template tie rods commonly used in concrete pouring, including tie rods and tie rod connectors. The tie rods include tie horizontal bars and tie vertical bars, which are connected by tie rod connectors. Horizontal tie rods are provided on both sides of the masonry wall 19. For the corresponding through-wall hole 1, multiple sets of through-wall holes 1 are opened along the height direction of the masonry wall 19 (two through-wall holes 1 at the same horizontal height constitute a set). The number of tie components 7 corresponds to the number and position of the through-wall holes 1 on the masonry wall 19. The two tie longitudinal rods pass through the corresponding through-wall holes 1 on the masonry wall 19 on both sides of the structural column (double-row tie longitudinal rods can also be set), and both ends of the tie longitudinal rods extend outside the masonry wall 19. The two tie horizontal rods are respectively clamped on the outside of the two secondary structure templates 1. The two ends of the tie horizontal rods are respectively connected to the ends of the two tie longitudinal rods in the same direction through tie rod connectors (double-row tie horizontal rods can also be set). Multiple spacers 10 are set between the inner side of the secondary structure template 1 (the side closer to the reinforcing member 6) and the outer side of the reinforcing member 6. The spacers 10 are used to prevent the reinforcing member 6 from deforming and shifting during the pouring of secondary structure concrete to form a layer and avoid the problem of exposed reinforcement.

[0030] like Figures 1-3 As shown, the shaping component 2 includes a shaping template 21 and a compression membrane 22. The shaping component 2 is custom-made. The dimensions of the shaping template 21 are customized according to the dimensions of the secondary structure, and the hardness of the shaping template 21 meets the requirements for concrete pouring and forming of the secondary structure. The shaping template 21 is preferably made of a plastic template with a certain degree of elasticity. The shaping template 21 is integrally formed and adopts a plate-like structure or a structure with a right-angled L-shaped cross-section. The shaping template 21 may selectively have vent holes (not shown in the figure), and the diameter of the vent holes (φ≤8mm) is relatively small. The compression membrane 22 surrounds the shaping template 21 and discharges the air in the concrete pouring cavity 9 through the compression membrane 22. The connection between the compression membrane 22 and the shaping template 21 maintains good sealing, so that a vacuum can be drawn through the compression membrane 22. The compression membrane 22 and the shaping template 21 form a compression cavity 11. Since there is a gap between the shaping template 21 and the top beam 8... There are gaps, and there will also be gaps at the joints of the template 21. When the height of the concrete in the concrete pouring cavity 9 exceeds the height of the secondary structure template 1, the air in the compression cavity 11 is removed, and the compression membrane 22 is pressed tightly against the template 21, creating a vacuum in the concrete pouring cavity 9. The compression membrane 22 is customized according to the template 21, and an air extraction port (not shown in the figure) is opened on the compression membrane 22. A vacuuming component is set at the air extraction port. When vacuuming through the air extraction port, the air in the concrete pouring cavity 9 is discharged through the gaps or the exhaust holes on the template 21. The vacuuming component is used to extract the air in the concrete pouring cavity 9. Before vacuuming, the overflow pipe 4 is sealed with a sealing cap and is in a closed state. After the compression membrane 22 is pressed tightly against the template 21, the concrete continues to be poured. Then, the air is extracted again through the vacuuming component on the overflow pipe 4, and the concrete continues to be poured, thereby ensuring the compactness of the concrete in the later stage of the secondary structure pouring.

[0031] The shaping template 21 adopts an L-shaped structure or a rectangular structure. When an L-shaped structure is adopted, it includes a shaping part 211 and a connecting part 212. The cross-section of the shaping part 211 is rectangular, and the right side of the shaping part 211 ( Figure 3 The left and right directions) are the inner side of the shaping template 21, and the left side of the shaping part 211 ( Figure 3 (in the left-right direction) connected to the connecting part 212, the bottom of the shaping part 211 has an L-shaped groove, the L-shaped groove is formed by the inward processing of the outer side (from left to right) of the shaping part 211 (or formed by the inward inward processing of the bottom outer part of the shaping part 211 towards the top), the cross-section of the L-shaped groove is a right angle L-shape, and the opening of the L-shaped groove faces left ( Figure 3 (in the left and right directions), the bottom of the shaping part 211 is the bottom of the shaping template 21, and the L-shaped groove is used to install the clamping plate 161.

[0032] The connecting part 212 has a right-angled trapezoidal cross-section. The connecting part 212 includes a connecting surface 2121 that adheres to the top beam plate 8 and inclined surfaces 2122 on opposite sides of the connecting surface 2121. It also includes a first plane 2123 and a second plane 2124 that are parallel to each other. The first plane 2123 and the second plane 2124 are located on opposite sides of the connecting surface 2121. The length of the first plane 2123 is less than the length of the second plane 2124. A pressing part 221 of the compression film 22 is arranged on the outer side of the first plane 2123. The pressing part 221 is attached to the top beam plate 8. The second plane 2124 is integrally connected to the left side of the shaping part 211. The connecting part 212 is located on the upper left side of the shaping part 211. The part of the left side of the shaping part 211 that is not connected to the connecting part 212 is the outer side of the shaping part 211. When the connecting part 212 is connected to the shaping part 211, the connecting surface 2121 of the connecting part 212 is flush with the top of the shaping part 211, together forming the top of the shaping template 21, and is installed on the top beam plate 8. The first plane 2123 and the inclined surface 2122 of the connecting part 212, as well as the outer side of the shaping part 211, together form the outer side of the shaping template 21. The venting holes on the shaping template 21 can be selectively opened in the shaping part 211 and are located below the connecting part 212. Figure 3 (Up and down direction), and located above the L-shaped groove at the bottom of the shaping part 211 ( Figure 3 up and down direction).

[0033] refer to Figure 3 The compression membrane 22 is disposed on the outside of the shaping template 21 (the compression membrane 22 can also be sleeved on the outside of the shaping template 21; when sleeved, the compression membrane 22 has an air extraction port on the outside of the shaping template 21, and an opening is left on the inside of the shaping template 21, so that the compression cavity 11 formed by the compression membrane 22 and the shaping template 21 communicates with the concrete pouring cavity 9. In order to ensure the vacuuming effect, the air extraction port preferably corresponds to the exhaust hole on the shaping template; or the compression membrane is sleeved on the outside of the shaping template and connected to the inside of the shaping template, and is used in the shaping process). An unclosed area is formed on the inner side of the template (at this time, the vent hole is opened in the unclosed area). The compression film 22 is arranged on the outer side of the shaping template 21, including the pressing part 221 arranged on the outer side of the first plane 2123 of the connecting part 212, and the part that extends sequentially to the first plane 2123, the inclined surface 2122, the outer side of the shaping part 211, the L-shaped groove and the splice of the shaping template 21 and the secondary structure template 1. The pressing part 221 is sealed and installed on the top beam plate 8, and is also sealed and installed at the splice of the shaping template 21 and the secondary structure template 1.

[0034] The shaping component 2 is arranged on top of the secondary structure template 1. In one preferred embodiment, referring to 4, the top of the shaping template 21 of the shaping component 2 is attached to the top beam plate 8. The compression film 22 also includes a pressing part 221 disposed on the outside of the connecting part 212 of the shaping template 21. The pressing part 221 is used to attach to the top beam plate 8. In order to ensure the sealing of the compression cavity 11 formed between the compression film 22 and the shaping template 21, a sealing gasket 12 is also provided at the pressing part 221. The sealing gasket 12 is used to make the pressing part 221 of the compression film 22 and the top beam plate 8 fit together. The beam slab 8 is pressed and sealed, and the compression membrane 22 can completely seal the concrete pouring cavity 9 from the outside, thereby ensuring the vacuuming effect. The sealing gasket 12 can be a sealing strip. After the compression membrane 22 is pressed onto the sealing gasket 12, a clamping strip is arranged on the outside for fixation. During subsequent vacuuming, when the pressure in the inner concrete pouring cavity 9 decreases (until vacuum), the flexible compression membrane 22 can automatically shrink and adhere tightly to the top beam slab 8 and the shaping template 21. Similarly, sealing gaskets 12 and pressure strips are also set at the joints between the compression membrane 22 and the masonry walls on both sides for sealing. Figure 5 A sealing gasket 23 is provided between the compression film 22 at the bottom of the shaping template 21 of the shaping component 2 and the top of the secondary structure template 1. The sealing gasket 23 is used to seal the shaping component 2 and the secondary structure template 1, so that when the vacuum is drawn through the compression cavity 11, the concrete pouring cavity 9 is a closed cavity, thereby ensuring that the secondary structure concrete is poured densely.

[0035] The inner side of the connection between the shaping component 2 and the secondary structure template 1 is also provided with sealing tape 14 (see reference). Figure 5 The shaping part 211 is flush with the inner pouring surface of the secondary structure template 1. The sealing tape 14 is simultaneously attached to the inner pouring surface of the shaping part 211 and the secondary structure template 1. By setting the sealing tape 14, the shaping component 2 and the secondary structure template 1 are sealed and spliced, ensuring that the secondary structure concrete poured after vacuuming is dense and free of bubbles.

[0036] A fixing component 16 (see reference) is also provided at the connection between the shaping component 2 and the secondary structure template 1. Figure 5The fixing component 16 is used to tighten the fixing component 2 and the secondary structure template 1. The fixing component 16 includes a clamping plate 161, a connecting crossbar 162, an adjusting lock 164, and a connecting longitudinal bar 163.

The upper part of the clamping plate 161 is arranged at the L-shaped groove of the shaped template 21, and the lower part of the clamping plate 161 is arranged on the outside of the secondary structure template 1. The top of the clamping plate 161 is attached to one right-angle side of the L-shaped groove, and the inner side of the clamping plate 161 is attached to the other right-angle side of the L-shaped groove (when the compression film is sleeved outside the shaped template or set on the outside of the shaped template, the top of the clamping plate is pressed tightly against the compression film at one right-angle side of the L-shaped groove, and the inner side of the clamping plate is attached to the compression film at the other right-angle side of the L-shaped groove).

The aforementioned tie assembly 7 and the fixing fastener 16 can adopt the same structure. The tie rod includes a tie crossbar and a tie longitudinal bar. The tie longitudinal bar is equivalent to the connecting crossbar 172 and is used to pass through the masonry wall 19. The tie crossbar is equivalent to the connecting longitudinal bar 173 and is used to clamp and fix the secondary structure template 1. The tie rod connector adopts the adjusting latch 164 to connect and fix the tie crossbar and the tie longitudinal bar.

When the compression membrane 22 of the shaping component 2 is vacuumed, the sealing cover 2 is closed, so that the overflow pipe 42 is threadedly connected to the sealing cover 2 and maintains good sealing performance.

[0039] In actual application, the first end of the pouring guide pipe 3 moves upward as the pouring height of the secondary structure concrete increases. Figure 1(Up and down direction) After the pouring height of the secondary structure concrete exceeds the pouring guide pipe 3 (that is, exceeds the pouring port on the secondary structure template), the vacuum component on the compression membrane 22 is opened to extract the air from the concrete pouring cavity 9. This causes the compression membrane 22 to contract, filling the gaps between the shaping component 2 and the secondary structure template 1, and between the shaping component 2 and the top beam 8. The compression membrane 22 remains compressed, and concrete pouring continues. After reaching the pouring pressure, the sealing cap one and / or sealing cap two are opened to continue discharging the air from the overflow pipe one 41 and / or overflow pipe two 42. In a preferred embodiment, the second end of the overflow pipe one 41 and overflow pipe two 42 (the end where the sealing cap one and sealing cap two are installed) is also covered with... The vacuuming component is installed, and the overflow pipe 41 and overflow pipe 42 are further vacuumed to further compress the gap between the shaping component 2 and the secondary structure template 1, and between the shaping component 2 and the top beam 8. Then, the concrete is poured. The second end of the overflow pipe 41 and / or the second end of the overflow pipe 42 are sealed again, and the secondary structure concrete is poured. When the secondary structure concrete is poured to the top beam 8 and squeezed to the overflow pipe 41 and overflow pipe 42, the sealing cap 1 and sealing cap 2 are opened. When the concrete is squeezed to the overflow pipe 41 and overflow pipe 42 and overflows, the overflow pipe 41 and overflow pipe 42 are slowly pulled out. The pouring ends when the concrete flows out of the second end of the overflow pipe 41 and the second end of the overflow pipe 42.

[0040] When pouring concrete for the secondary structure shaping components, the preferred implementation method is as follows: First, a vacuum is drawn through the compression membrane 22, then concrete is poured and vibrated. Then, the vacuuming component is closed to keep the compression membrane 22 compressed, maintaining the sealing caps on overflow pipe 1 41 and overflow pipe 2 22 in a closed and sealed state. Simultaneously, air is extracted from the concrete pouring cavity 9 through overflow pipe 1 41 and overflow pipe 2 42, further compressing the compression membrane 22. Concrete pouring continues. Because overflow pipe 1 41 is lower in height, concrete flows into overflow pipe 1 41 first. When vacuuming of overflow pipe 1 41 is no longer possible, the vacuuming component on overflow pipe 1 41 is closed, and vacuuming continues from overflow pipe 2 42. Meanwhile, continue pouring concrete. When it is no longer possible to vacuum the overflow pipe 42, close the vacuuming component on the overflow pipe 42 and continue pouring concrete until the pouring pressure reaches the design pouring pressure. At this time, open the sealing cap of the overflow pipe 4 (including the sealing cap 1 of the overflow pipe 41 and the sealing cap 2 of the overflow pipe 42) and continue pouring the secondary structure concrete. When the secondary structure concrete is poured to the top beam 8 and squeezed into the overflow pipe 41 and the overflow pipe 42, observe that the concrete is squeezed into the overflow pipe 41 and the overflow pipe 42 and overflows. Then, slowly pull out the overflow pipe 41 and the overflow pipe 42. The pouring ends when the concrete flows out of the second end of the overflow pipe 41 and the second end of the overflow pipe 42.

[0041] It is worth noting that when extracting overflow pipe 41 and overflow pipe 42, the extraction length of overflow pipe 41 and overflow pipe 42 should be marked first, with the extraction length determined by the extent that overflow pipe 41 and overflow pipe 42 have been extracted and removed from the main body of the secondary structure.

[0042] Another preferred embodiment is as follows: Switches are respectively installed on overflow pipe 41 and overflow pipe 42 to open them. When the poured concrete flows out of the second end of overflow pipe 41 and overflow pipe 42, the switches are closed to cut off the grout flow while ensuring the concrete is fully saturated, thus preventing excessive grout leakage. After the secondary structure has solidified and the formwork has been removed, excess concrete at the overflow pipe 41 and overflow pipe 42 is removed, ground, and plastered.

[0043] By setting up overflow pipe 1 41 and overflow pipe 2 42, with a height difference between them, and by using overflow pipe 1 41 and overflow pipe 2 42 to perform vacuuming in stages and completing the pouring, it is possible to fully ensure that the concrete at the top of the secondary structure is completely sealed, that the pouring is dense, that the integrity of the top concrete is ensured, and that the overall structure is guaranteed.

[0044] When pouring concrete for the secondary structure, the vibrator 18 should be turned on. The vibration of the vibrator 18 should be strengthened, especially when pouring the bottom of the secondary structure, the pouring port near the secondary structure formwork 1, and the top of the secondary structure. When pouring the top of the secondary structure, the vibrator 18 should be placed near the pouring port on the secondary structure formwork 1. To prevent over-vibration, the vibrator 18 should be vibrated at intervals.

Various substitutions, modifications, and improvements made by those skilled in the art without departing from the principles and scope of this utility model should be included within the protection scope of this utility model.
