Description

Technical Field

[0002] Material transfer holes are mainly used in the construction of high-rise buildings to provide a convenient temporary passage for concrete transportation and material transfer between floors. Usually, in the floor slab or shear wall structure, an integrated embedded mold is used to reserve the material transfer hole, and the hole is formed after the concrete pouring is completed; after the concrete transportation or material transfer is completed, in order to restore the integrity and structural strength of the building, the material transfer hole needs to be blocked, usually by concrete backfilling. However, due to the smooth surface of the concrete at the material transfer hole, the physical bite between the new and old concrete is weak, and the bonding interface is prone to stratification and peeling, which affects the quality of the blocking; therefore, the hole surface must be artificially or mechanically roughened before blocking to form a rough and irregular interface to improve the bonding strength between the new and old concrete.

[0003] However, roughening the surfaces of the material transfer holes manually or mechanically one by one increases the number of construction steps and prolongs the plugging process. Manual roughening is time-consuming and labor-intensive, which increases the workload and labor intensity of construction personnel. Furthermore, manual or mechanical roughening may result in uneven roughening in some areas, leading to poor bonding and reducing the structural strength of the plugging area.

The reserved mold for the material transfer hole includes a base 1, two first side panels 2, two second side panels 3, and a textured protrusion 4, wherein the base 1 is a hollow structure, and the upper end surface of the base 1 is rectangular; the two first side panels 2 and / or the two second side panels 3 are detachably mounted on the base 1, the two first side panels 2 are respectively arranged on the opposite sides of the upper end surface rectangle of the base 1, and the two second side panels 3 are respectively arranged on the other opposite sides of the upper end surface rectangle of the base 1, and the two first side panels 2, the two second side panels 3 and the base 1 are enclosed to form a frame tube structure with closed peripheries and upper and lower openings; the outer side walls of the two first side panels 2 and / or the two second side panels 3 are provided with a textured protrusion 4.

[0047] By arranging the textured protrusions 4 on the outer walls of the two first side panels 2 and / or the two second side panels 3, these textured protrusions 4 can automatically form textures on the inner surface of the material transfer hole 8 during the process of pouring concrete to form the material transfer hole 8; through the generation of these textures, the inner surface of the material transfer hole 8 has sufficient roughness and texture structure, and when the material transfer hole 8 is blocked later, the bonding performance between the later poured concrete and the original structural concrete is improved; it directly solves the cumbersome steps of roughening in the traditional blocking process, eliminates the roughening process, directly reduces the complexity of manual operation, reduces labor costs, and not only saves construction time, but also reduces labor costs. time, and significantly improves the sealing efficiency, making the construction process smoother; the two first side panels 2 and / or the two second side panels 3 are detachable, so that the construction personnel can adjust the use of the mold as needed and flexibly adapt to different construction requirements; at the same time, this design is also convenient for the disassembly and cleaning of the mold, so that the mold can be reused many times, further saving costs and improving economic benefits; the two first side panels 2, the two second side panels 3 and the base 1 are enclosed to form a closed frame tube with closed sides and upper and lower openings, which ensures that there will be no leakage or water seepage during the pouring of concrete, thereby ensuring the integrity of the reserved shape of the material transfer opening 8.

[0048] It should be noted that the reserved mold for the material transfer hole can be made of, but is not limited to, aluminum metal, and no specific limitation is made here.

[0049] like Figure 2 As shown, in some embodiments, the textured protrusion 4 is configured as a plurality of reinforcing ribs, the plurality of reinforcing ribs are fixedly connected to the outer side walls of the two first side panels 2 and / or the outer side walls of the two second side panels 3, the plurality of reinforcing ribs are arranged along the width direction of the two first side panels 2 and / or the two second side panels 3, and are spaced and distributed side by side along the length direction of the two first side panels 2 and / or the two second side panels 3; wherein the textured protrusion 4 is configured as a plurality of reinforcing ribs distributed along the outer side walls of the two first side panels 2 and / or the two second side panels 3, the convex structure of the reinforcing ribs enables the outer surface of the mold to have sufficient roughness and texture, so that the surface of the concrete after pouring is more firmly combined with the original structure; at the same time, the reinforcing ribs themselves can enhance the rigidity of the first side panel 2 and / or the second side panel 3, so that the mold can withstand greater external force and pressure during the concrete pouring process, reduce the risk of deformation, and increase the service life. It should be noted that the arrangement of the reinforcing ribs can be arranged according to actual needs, and no specific limitation is made here; and the reinforcing ribs can be connected to the first side panel 2 and / or the second side panel 3 by welding, but not limited to. It can be understood that the reinforcing ribs can be but are not limited to steel bars, and no specific limitation is made here.

[0050] In other embodiments, the patterned protrusion 4 may also be cast integrally with the first side panel 2 and / or the second side panel 3. This eliminates the connection gaps or welding parts that may exist in traditional designs, avoids potential weaknesses of the connection points during the force-bearing process, has stronger integrity, can withstand greater external pressure, and improves the load-bearing capacity of the mold.

[0051] like Figures 7 and 8As shown, in order to enhance the stability of the mold, in some embodiments, the reserved mold for the material transfer hole also includes a limiter 5 and a telescopic connection assembly 6, the limiters 5 are respectively arranged on the opposite sides of the rectangular edge of the upper end surface of the base 1, and the inner side of the limiter 5 can abut against the two opposite first side panels 2 and / or the two opposite second side panels 3 close to the base 1 to limit the displacement of the two opposite first side panels 2 and / or the two opposite second side panels 3 close to the base 1; the telescopic connection assembly 6 can be telescopically arranged between the two opposite first side panels 2 and / or the two opposite second side panels 3, and the two ends of the telescopic connection assembly 6 can be detachably connected to the inner side walls of the two opposite first side panels 2 and / or the two opposite second side panels 3, so as to connect and support the two opposite first side panels 2 and / or the two opposite second side panels 3; wherein, through the coordinated use of the limiter 5 and the telescopic connection assembly 6, it is ensured that The mold will not be deformed or displaced due to external factors during use, which improves the stability and accuracy of the mold during concrete pouring; the limiter 5 is arranged on the opposite side of the rectangular edge of the upper end face of the base 1, which can effectively limit the displacement of the two opposite first side panels 2 and / or the second side panels 3 close to one end of the base 1, so that the side panels will not be displaced during the pouring process. During the construction process, the limiter 5 ensures the stability of the mold and the shape accuracy of the reserved opening; the two ends of the telescopic connection assembly 6 are detachably connected to the inner side walls of the two opposite first side panels 2 and / or the two opposite second side panels 3 to help connect and support the two opposite first side panels 2 and / or the two opposite second side panels 3; during the construction process, the construction personnel can adjust the length of the telescopic connection assembly 6 as needed to ensure that the two side panels of the mold maintain an appropriate spacing, so that they can effectively support them when concrete is poured to prevent the mold from deforming or becoming unstable.

[0052] Furthermore, the stopper 5 can be a metal barrier strip, which is laid on the base 1 around the rectangular edge of the upper end surface of the base 1. The metal material used for the metal barrier strip, such as aluminum alloy or steel, has excellent compression resistance, deformation resistance and impact resistance. Even when a large pressure is applied during the pouring process, the metal barrier strip can maintain stability, avoid loosening or deformation of the mold structure due to external force, and ensure that the reserved shape of the material transfer hole 8 is accurate; and aluminum alloy or steel is usually easier to obtain on site. If waste aluminum alloy steel bars are used to make metal barrier strips, waste can be reused, which not only reduces the cost of waste treatment, but also better responds to environmental protection requirements and reduces project costs. In addition, the metal barrier strip is easy to install and is easy to fix on the base 1.

[0053] Combination Figure 1 and Figure 4As shown, in order to further increase the support of the mold, in some embodiments, a plurality of telescopic connection components 6 are connected between the two relative first side panels 2, and the plurality of telescopic connection components 6 are evenly arranged along the length direction of the two relative first side panels 2; and / or, a plurality of telescopic connection components 6 are connected between the two relative second side panels 3, and the plurality of telescopic connection components 6 are evenly arranged along the length direction of the two relative second side panels 3; wherein, by respectively arranging a plurality of telescopic support components between the two relative first side panels 2 and / or the two relative second side panels 3, the force between the first side panels 2 and / or the second side panels 3 and the pressure applied from the outside can be evenly shared, thereby preventing deformation or loosening of the mold due to uneven force during the pouring process, and improving the overall support of the mold when it is subjected to the pressure of concrete pouring.

[0054] like Figure 6 As shown, in order to improve the adjustment flexibility of the telescopic connection assembly 6, in some embodiments, the telescopic connection assembly 6 includes a main rod 61 and a telescopic rod 62, the main rod 61 is sleeved on the telescopic rod 62 and can be connected by a thread; the end of the main rod 61 away from the telescopic rod 62 is connected to the inner wall of a first side panel 2, and the end of the telescopic rod 62 away from the main rod 61 is connected to the inner wall of another first side panel 2; and / or, the end of the main rod 61 away from the telescopic rod 62 is connected to the inner wall of a second side panel 3, and the end of the telescopic rod 62 away from the main rod 61 is connected to the inner wall of another second side panel 3; wherein, by threading the main rod 61 and the telescopic rod 62, the relative position of the main rod 61 and the telescopic rod 62 can be precisely adjusted, and the construction personnel can fine-tune the distance between the two first side panels 2 and / or the distance between the two second side panels 3 according to actual needs, so as to adapt to material transfer holes 8 of different specifications.

[0055] Continue as Figure 6 As shown, in order to improve the stability of the telescopic connection assembly 6, in some embodiments, the telescopic connection assembly 6 also includes a locking member 63, which is arranged at the threaded connection between the main rod 61 and the telescopic rod 62, and the locking member 63 can fix the relative position of the main rod 61 and the telescopic rod 62; under the pouring of concrete, vibration or external force, the simple threaded connection between the main rod 61 and the telescopic rod 62 may loosen due to vibration, and the locking member 63 can effectively prevent the relative slip between the main rod 61 and the telescopic rod 62, thereby improving the stability of the telescopic connection assembly 6. Further, the locking member 63 can be designed to open a tightening hole at the intersection of the main rod 61 and the telescopic rod 62 on the main rod 61, and cooperate with a stop pin. When the main rod 61 and the telescopic rod 62 are adjusted to the desired position, the stop pin can be inserted into the tightening hole to fix the telescopic rod 62 and prevent it from sliding. In other embodiments, the locking member 63 can be, but is not limited to, a wedge locking mechanism, which is not specifically limited here.

[0056] like Figure 4 and Figure 5As shown, in order to facilitate the installation and disassembly of the telescopic connection assembly 6, in some embodiments, the inner side walls of the two opposite first side panels 2 and / or the inner side walls of the two opposite second side panels 3 are symmetrically provided with fixing members 7, and the two ends of the telescopic connection assembly 6 are respectively clamped on the symmetrically positioned fixing members 7; wherein the fixing member 7 provides a fixed installation position for the telescopic connection assembly 6, and the construction personnel can quickly install it according to the preset position of the fixing member 7; at the same time, a connection method in which both ends of the telescopic connection assembly 6 are clamped with the symmetrically arranged fixing members 7 is adopted, and a clamping type fixing member 7 can be selected, without the need for additional fastening bolts or welding methods, and the construction personnel can directly clamp the two ends of the telescopic connection assembly 6 into the fixing member 7, thereby reducing the installation steps and saving time. When the telescopic connection assembly 6 needs to be adjusted or replaced, it can be disassembled by simply releasing the clamping, avoiding cumbersome thread tightening or welding removal operations, and improving the convenience of maintenance; at the same time, due to the symmetrical arrangement of the fixing member 7, it can provide uniform force support for the telescopic connection assembly 6, reduce the force deformation of the first side panel 2 and / or the second side panel 3, and improve the rigidity of the mold as a whole.

[0057] like Figures 1 to 3 As shown, in order to facilitate concrete filling and improve the sealing quality, in some embodiments, the distance between the two first side panels 2 and / or the two second side panels 3 gradually increases from the side close to the base 1 to the side away from the base 1; wherein, since the distance between the two first side panels 2 and / or the two first side panels 2 gradually increases from the bottom to the top, a trumpet-shaped or conical structure is formed, which can effectively guide the concrete to fill into the formed material transfer hole 8, reduce bubbles or voids, and improve the density of the sealing.

[0058] In order to facilitate the assembly of the mold, in some embodiments, the mold reserved for the material transfer hole also includes a handle, which is installed on the side of the two first side panels 2 and / or the two second side panels 3 away from the base 1; wherein the handle can be used as a force application point and a gripping point, and the construction personnel can directly grasp the handle to carry the two first side panels 2 and / or the two second side panels 3, thereby improving the convenience of mold assembly; at the same time, when removing the mold, the handle also provides a stable force point, and the construction personnel can apply appropriate external force through the handle to remove the mold from the reserved hole, making the mold removal smoother.

[0059] In other embodiments, the two opposite first side panels 2 and / or the two opposite second side panels 3 can be detachably connected to the base 1 by bolts, wherein the detachable connection with bolts can quickly install or remove the first side panels 2 and / or the second side panels 3, thereby simplifying the construction process and improving construction efficiency.

[0060] Please refer to Figures 9 and 10 As shown, the present invention also provides a construction method for a material transfer hole, using the reserved mold for the material transfer hole in any of the above embodiments, comprising the following steps:

[0061] S1: Assemble the reserved mold for the material transfer hole and place it accurately and firmly in the predetermined position;

[0062] S2: pour concrete according to construction requirements to form a reserved channel for the material transfer opening 8;

[0063] S3: Remove the reserved mold for the material transfer hole, and use the reserved channel of the material transfer hole 8 for material transportation;

[0064] S4: After the material transportation is completed, check the material transfer hole 8 and clean the impurities on the inner surface of the material transfer hole 8;

[0065] S5: according to the position and size of the material transfer hole 8, the template is supported by the bracket so that the template is tightly pressed against the bottom of the material transfer hole 8 to block the bottom of the material transfer hole 8;

[0066] S6: Tie a double layer of steel bars 9 in the material transfer opening 8, each layer of steel bars 9 includes a plurality of transverse bars 91 and a plurality of vertical bars 92, the plurality of transverse bars 91 are evenly arranged along the width direction of the material transfer opening 8; the plurality of vertical bars 92 are evenly arranged along the length direction of the material transfer opening 8; the double layer of steel bars 9 are distributed along the thickness direction of the material transfer opening 8, and the double layer of steel bars 9 are separated by concrete pads 10;

[0067] S7: Wetting the material transfer hole 8 with water, using expansive concrete for one-time pouring, and vibrating the expansive concrete;

[0068] S8: After the expansion concrete is initially set, the surface of the material transfer opening 8 is polished.

[0069] The construction method of the material transfer hole 8 is to set the patterned protrusions 4 on the outer walls of the two first side panels 2 and / or the two second side panels 3 by using the reserved mold for the material transfer hole. These patterned protrusions 4 can automatically form patterns on the inner surface of the material transfer hole 8 during the process of pouring concrete to form the material transfer hole 8; through the generation of these textures, the inner surface of the material transfer hole 8 has sufficient roughness and texture structure, and when the material transfer hole 8 is blocked later, the bonding performance between the later poured concrete and the original structural concrete is improved; it directly solves the cumbersome steps of roughening in the traditional blocking process, eliminates the roughening process, directly reduces the complexity of manual operation, reduces labor costs, not only saves construction time, but also significantly improves the blocking efficiency, making the construction process smoother. In order to facilitate the later demoulding, a release agent can be brushed on the outside of the reserved mold for the material transfer hole.

[0070] The construction personnel can check the material transfer hole 8 to determine whether there are cracks or damages, and take appropriate measures if necessary; clean the impurities on the inner surface of the material transfer hole 8 to ensure that the surface of the material transfer hole 8 is clean and dry; and press the template tightly against the bottom of the material transfer hole 8 to effectively prevent leakage and deformation during concrete pouring. In order to facilitate demoulding later, the template can be made of aluminum template with a release agent on its surface; when the concrete reaches a certain strength, the template can be removed. Figures 9 and 10 As shown, by tying a double-layer steel bar layer 9 in the material transfer hole 8 during the process of blocking the material transfer hole 8, the compressive strength of the material transfer hole 8 is effectively increased, which can effectively solve the problem that the single-layer steel bar layer 9 cannot provide sufficient support; because the double-layer steel bar layer 9 is separated by a concrete pad 10, the position of the steel bar layer 9 is better fixed, thereby avoiding the steel bar layer 9 from being offset due to concrete shrinkage and reducing the risk of cracking; the use of expansive concrete can effectively prevent the concrete from shrinking during the hardening process, ensuring the compactness and stability of the blocking area. Among them, the concrete pad 10 can be evenly placed between the two layers of steel bars 9, making it more stable. By wetting the material transfer hole 8 with water, it is helpful to enhance the bonding force between the expansive concrete and the hole surface; the expansive concrete is vibrated to effectively eliminate bubbles and voids in the concrete and improve the compactness of the concrete. By finishing the surface of the material transfer hole 8 after the expansive concrete is initially set, it can ensure that the surface of the blocking part is flat.

[0071] Therefore, the construction method of the material transfer opening eliminates the roughening process before sealing, simplifies the construction process, shortens the construction period, reduces labor costs, improves construction efficiency, and makes the concrete after sealing tightly integrated with the original structure, ensuring the bonding performance and structural strength of the sealing area, and avoiding the problem of cracking in the later stage.
