Description

Technical Field

[0001] The invention belongs to the field of building prefabricated panels, and in particular relates to an assembled template for secondary structure construction columns. Background Art

[0002] During secondary structure construction, the efficiency and quality of the structural column formwork system directly impact project progress and structural safety. Traditional structural column formwork technology suffers from the following technical bottlenecks: 1. Poor reinforcement system reliability: Holes for tension bolts are manually positioned using a drill rig. Inaccuracies in hole placement can easily cause formwork misalignment, increasing grout leakage. Furthermore, the drilled holes can interfere with the reinforcement cage, preventing the tension bolts from penetrating.

[0003] 2. Low efficiency of template assembly: The whole plate is usually cut to form the feed port, which increases the breakage rate of the template and makes it difficult to reuse the waste after cutting; the feed port is mostly assembled by plate materials and bolts, which is inefficient; when holes are opened on the surface of the plate, in order to reduce the number of punching holes next time and ensure the structural strength of the template, the two relative templates need to be matched one by one, which greatly reduces the efficiency of the next assembly; and when the template is built, in order to ensure the support and stability of the template, it is also necessary to use diagonal braces and wall connecting parts, which further affects the construction efficiency.

[0004] 3. Unstable concrete pouring quality: The traditional feed hopper and formwork are temporarily fixed with bolts. During vibration pouring, the interface between the two is prone to displacement, resulting in an increase in the honeycomb surface defect rate of the structural column.

[0005] In order to improve the assembly efficiency during the formwork assembly process before pouring the secondary structure construction columns while ensuring the strength after the formwork is assembled, and thus ensure the subsequent concrete pouring and molding effect; the present invention provides an assembled formwork for secondary structure construction columns.

The adapters are provided with two types of sub-parts and female parts. One side of the sub-part is provided with a convex block that matches the concave groove on the formwork support plate; one side of the female part is provided with a concave groove that matches the convex block on the formwork support plate; and the outer sides of the sub-part and the female part are jointly clamped with side cover plates.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-7 This application is described in further detail.

[0028] Example 1

[0029] When constructing structural columns using double-sided formwork, please refer to Figure 1 , a secondary structure structural column assembled formwork, including a formwork plate 1 and a feed hopper 2; the formwork plate 1 has two sides along its length direction, one of which is provided with a concave groove 12, and the other side is provided with a convex block 13, and several formwork plates 1 are sequentially plugged into and matched with the concave groove 12 and the convex block 13 to form a single-sided formwork; wherein the width of the concave groove 12 is 1.05 times that of the convex block 13, so as to reduce the infiltration of mortar in the joint after plugging and matching; two single-sided formworks are arranged in a front-to-back distribution, and the concave grooves 12 and convex blocks 13 of the two single-sided formworks are arranged in opposite positions; the purpose of setting the opposite position is to increase the structural strength of the formwork after assembly, and effectively prevent the vibration of the concrete poured in the later stage from causing the assembled structure to loosen and shake.

[0030] Multiple formwork boards 1 are spliced together to form a single-sided formwork, which is conducive to splicing single-sided formwork of corresponding length according to the actual width of the cast structural column. At the same time, the formwork boards 1 are plugged in and matched with the concave grooves 12 and the convex blocks 13 to reduce the permeability of the mortar, and a single formwork board 1 is easier to transport.

[0031] See Figure 1 and Figure 2 , the height of several formwork plates 1 in the middle of the single-sided formwork on one side is slightly lower than the height of the formwork plates 1 at the edge positions on both sides, the upper end surfaces of several formwork plates 1 in the middle are provided with a convex structure, the lower end of the feed hopper 2 is clamped in the inside of the convex structure, and the left and right sides of the feed hopper 2 are respectively provided with a concave groove 12 and a convex block 13 that are plugged into the side walls of the formwork plates 1 at the corresponding positions; the feed hopper 2 with an integrated setting does not require cutting of the formwork plates 1, thereby ensuring the reuse rate of the formwork plates 1, and at the same time, the splicing method between the feed hopper 2 and the formwork plates 1 is the same as the clamping method between the formwork plates 1 and the formwork plates 1, which greatly improves the efficiency of the subsequent assembly, and the feed hopper 2 can also be locked into an integrated structure with the formwork plates 1 on the adjacent side by the same clamping method, which greatly enhances the structural strength of the assembled feed hopper 2, and does not require secondary reinforcement such as bolts and braces in the later stage.

[0032] See Figure 1 and Figure 3 Each mold support plate 1 is evenly provided with a through installation groove 11 from top to bottom; the installation grooves 11 are evenly provided on the mold support plate 1 to form a standardized structure, which effectively avoids the position deviation of the hole opening in the later stage and ensures the positioning accuracy.

[0033] See Figure 1 and Figure 3 , a blocking piece 3 is correspondingly connected in the installation groove 11; the blocking piece 3 is set to a shape that is compatible with the installation groove 11; the installation groove 11 is composed of a rectangular outer layer and an elliptical inner layer; the double-layer structure of the installation groove 11 can effectively ensure that the blocking piece 3 can be removed together with the formwork support plate 1 during the later demoulding; the blocking piece 3 is of two types, one of which is a perforated type and the other is a non-perforated type, wherein the perforated blocking piece 3 has a through hole, and the non-perforated blocking piece 3 is a closed structure.

[0034] See Figure 1 and Figure 4 The same type of blocking pieces 3 are installed at corresponding positions on the two opposite single-sided templates, wherein the holes on the two opposite perforated blocking pieces 3 are embedded with rubber sleeves 32, and the corresponding two rubber sleeves 32 are commonly penetrated by tension bolts 4. The diameter range of the tension bolts 4 is M12-M16. By setting two types of blocking pieces 3, the tension bolts 4 can be installed in appropriate positions according to actual requirements.

[0035] The perforated sealing member 3 is embedded with a rubber sleeve 32, which effectively forms a self-compensating sealing structure at the connection position of the tension bolt 4 to prevent mortar leakage. At the same time, the design of the rubber sleeve 32 is conducive to separating it from the tension bolt 4 that is solidified integrally with the structural column during later demolding.

[0036] See Figure 1 All the tension bolts 4 at the same horizontal position on the single-sided formwork are commonly penetrated by a transverse pressure plate 5 that fits the outer wall of the blocking piece 3; the setting of the transverse pressure plate 5 can form a tightening and self-locking for the single-sided formwork, effectively ensuring the structural strength of the overall spliced formwork.

[0037] It should be noted that when placing the blocking member 3 inside the installation slot 11, the orientation of the hole on the opening blocking member 3 is adjusted to avoid interference between the penetrating tension bolts 4 and the steel cage inside the cast structural column.

[0038] See Figure 3 and Figure 4 The side wall of the installation slot 11 is provided with a locking slot 111; the blocking member 3 includes a blocking cover plate 31, and an elliptical protrusion is provided at one end of the elliptical inner layer of the blocking cover plate 31 facing the installation slot 11, and four locking members 311 are provided on the inner side of the blocking cover plate 31. The locking member 311 is composed of a locking rod, a guide rod and a grip rod in series. A spring is provided on the outside of the guide rod, and the locking rod cooperates with the locking slot 111. The grip rod is located on the outside of the blocking cover plate 31. By pinching the grip rod, the locking rod can be driven to move, so that the locking rods are adjusted to be close to each other and placed along the entrance of the lock slot 111, and then the grip rod can be released.

[0039] You can choose a perforated or non-perforated sealing piece 3 and adjust the position of the hole on the perforated sealing piece 3 according to actual needs. When installing the sealing piece 3, you only need to pinch the grip to move the locking rod; by adjusting the position of the locking rod inside the lock groove 111, you can replace different types of sealing pieces 3 or adjust the hole position of the perforated sealing piece 3.

[0040] Example 2

[0041] When a three-sided formwork is required to construct a structural column, an adapter 6 needs to be added on the same side of two single-sided formworks, such as Figure 5As shown, the adapter 6 is provided with two types of child and female accessories. Since the concave grooves 12 and convex blocks 13 of the two single-sided templates are set in opposite positions when two single-sided templates are placed, one side of the child accessory is provided with a convex block 13 that matches the concave groove 12 on the template support plate 1; one side of the female accessory is provided with a concave groove 12 that matches the convex block 13 on the template support plate 1; the outer walls of the child and female accessories are jointly clamped with a side cover plate 7, and the subsequent demolding is facilitated by the clamping method instead of the plug-in method of matching the convex block 13 and the concave groove 12. However, the clamping method reduces the connection strength between the side cover plate 7 and the single-sided templates on both sides. The traditional method requires the use of diagonal braces and wall connecting parts, which greatly reduces the efficiency of the mold.

[0042] In order to ensure that the outer wall of the side cover plate 7 and the pressure plate assembly 8 are tightly fitted, refer to Figure 5 and Figure 7 The horizontal pressure plate 5 has a rectangular through-slot 51 on one side, with a locking bolt 52 threadedly connected thereto. Two opposing rectangular through-slots 51 on the front and rear sides are slidably mounted together within these two slots. By snapping the pressure plate assemblies 8 into the rectangular through-slots 51 and operating the locking bolts 52 to press the pressure plate assemblies 8 against the male and female fittings on either side, an integrated structure is formed. This simple operation ensures the overall structural strength of the mold after enclosing while significantly reducing the time spent on enclosing and removing the mold.

[0043] See Figure 5 、 Figure 6 and Figure 7 The pressure plate assembly 8 includes a rectangular plate 81, a positioning groove 82 is provided in the middle of the rectangular plate 81, and mounting grooves 83 are provided on both sides of the rectangular plate 81. Connectors 84 are provided inside the mounting grooves 83. The rectangular plate 81 is fixed with an end cover plate 85 by bolts at its four corners, and a positioning block 86 is provided in the middle of the end cover plate 85 to match the positioning groove 82; the connecting member 84 includes a connecting rod 841 with a positioning hole provided inside, and the end of the locking bolt 52 is clamped inside the positioning hole. A convex hole 842 is provided inside the connecting rod 841, and a limiting column 843 is provided inside the convex hole 842. A limiting plate 844 is provided inside the limiting column 843, and a limiting spring is provided on the outer wall of the limiting column 843, one end of which is in contact with the limiting plate 844 and the other end of which is in contact with the bottom wall of the convex hole 842; the end cover plate 85 is provided with two clamping blocks 845 that are one-to-one engaged with the upper end grooves of the convex hole 842, and the clamping blocks 845 are in contact with the outer wall of the limiting plate 844.

[0044] The provided pressure plate assembly 8 can facilitate the insertion of the connecting rod 841 into the rectangular through-groove 51 of the corresponding transverse pressure plate 5, and after the connecting member 84 is engaged with the upper end groove of the convex hole 842 through the clamping block 845 to position the limit plate 844, it is convenient for the connecting rod 841 to be pulled and extended, so as to facilitate its maintenance at the minimum length. At the same time, the length compensation in actual use can be achieved by pulling the connecting rod 841, which facilitates the alignment of the locking bolt 52 with the positioning hole on the connecting rod 841.

[0045] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention's description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
