Description

Technical Field

[0001] This utility model belongs to the field of building formwork, and particularly relates to a tool-type multi-functional assembly well-type formwork for mechanized installation and dismantling. Background Technology

[0002] Currently, the main types of scaffolding used in domestic construction, bridge and tunnel construction include coupler-type scaffolding, frame scaffolding, cup-lock scaffolding, disc-lock scaffolding, and aluminum alloy scaffolding.

[0003] Among various types of scaffolding, the main method relies on manual assembly and connection of individual pieces at high altitudes to form the corresponding scaffolding to meet construction needs. Therefore, the installation and dismantling work is extensive, labor-intensive, time-consuming, and poses significant safety hazards. Some parts are easily lost, resulting in a large workload for recycling. In addition, there are numerous locations and wide areas, making management inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a tool-like formwork that can be assembled at fixed points on the ground, transforming scattered high-altitude operations into on-demand assembly at fixed points on the ground. The size of various assembly well-type formworks is limited to not exceeding the maximum lifting capacity of the crane, so as to achieve the purpose of using mechanical hoisting and installation, thereby solving various problems encountered in the prior art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0006] Assemble a well-type mold frame, characterized in that it includes welded uprights and welded horizontal bars. A pair of parallel welded uprights are connected by several welded horizontal bars to form a well-type mold frame component. Multiple well-type mold frame components are horizontally assembled together by horizontal assembly connecting rods to form a mold frame.

[0007] The top of the welded upright is provided with a connecting component, which is longitudinally connected to the well-type mold structure component;

[0008] The welded uprights and welded horizontals are hollow rods.

[0009] Furthermore, the welded upright is provided with several horizontal assembly reinforcement positioning grooves, and the two ends of the horizontal assembly connecting rod are connected to the horizontal assembly reinforcement positioning grooves on the adjacent well-type mold structure components.

[0010] Furthermore, the horizontal assembly connecting rod has connecting plates at both ends, and the connecting plates engage with the horizontal assembly reinforcing positioning groove; the horizontal assembly reinforcing positioning groove is provided with bolts, and the connecting plates are provided with guide slots that cooperate with the bolts.

[0011] Furthermore, the connecting component is a cross-shaped positioning bolt, which is movably mounted on the upper node connecting plate, and the upper node connecting plate is fixed to one end of the welded upright.

[0012] Furthermore, the outer contour of the cross-shaped positioning bolt is conical, the cross-section is a staggered cross shape, and a limiting groove is provided in the middle. The upper node connecting plate is provided with a slot that cooperates with the cross-shaped positioning bolt.

[0013] Furthermore, the horizontal assembly connecting rod is provided with a pair of connecting plates, and the connecting plates are movably provided with locking plates, and the horizontal assembly reinforcing positioning groove is provided with locking heads.

[0014] Furthermore, the welded upright is provided with an upper node connecting bolt reinforcement positioning groove and a lower node connecting bolt reinforcement positioning groove at both ends. Both the upper node connecting bolt reinforcement positioning groove and the lower node connecting bolt reinforcement positioning groove are provided with U-shaped grooves, which are fixed by connecting bolts.

[0015] Furthermore, the upper node connecting bolt reinforcing positioning groove is rectangular, and the U-shaped groove above it extends from the upper surface to the side. The upper node connecting bolt reinforcing positioning groove is provided with a bolt limiting groove, and the connecting bolt is locked in the bolt limiting groove with the bolt head protruding from the U-shaped groove.

[0016] Furthermore, the reinforcing positioning groove includes a fixed panel, an upper limit groove plate, and a lower limit groove plate. The fixed panel is provided with screws that cooperate with the guide groove. The upper limit groove plate and the lower limit groove plate are located at the two ends of the fixed panel and have a certain gap with the fixed panel. The upper limit groove plate and the lower limit groove plate are distributed on both sides of the fixed panel. The locking head is located on the lower limit groove plate.

[0017] Furthermore, a slanted liner connecting plate is provided at the connection between the welded horizontal bar and the welded vertical bar, and a vertical slanted liner assembly connecting rod is connected to the slanted liner connecting plate. A bottom support fine-tuning bolt is connected below the welded vertical bar.

[0018] The technical solution of this utility model has the following advantages:

[0019] 1. The technical solution of this application mainly uses the same structural members as coupler-type scaffolding. This has the advantage of allowing the technical solution to continue using existing, compliant steel pipe materials. It also allows existing coupler-type scaffolding to be converted into the technical solution of this application through reprocessing (partial modification), reducing material waste and financial losses for the original scaffolding owners, as well as lowering the financial and material investment required for the popularization of new technologies. Furthermore, it allows for compatibility with existing coupler-type scaffolding during the early promotion and transition periods of this technology.

[0020] 2. In a project, two or more standard well-type formwork components are generally assembled into an independent single-port assembled well-type formwork, or they can be assembled into a multi-port assembled well-type formwork for use in the project. They are then installed and connected continuously to meet the needs of the project.

[0021] 3. During construction, mechanical hoisting and forklift transportation (or manual transportation using a two-wheeled cart) can be used to transfer the equipment to the next process for continued use, reducing the amount of disassembly and assembly work required for repeated use (saving time and labor), and improving work efficiency and project economic benefits.

[0022] 4. At the end of the project, the assembled well-type formwork in this application can be sorted and stacked (by planar standard well-type formwork components and rods for assembly connection), which facilitates warehousing (loading) and long-distance transportation.

[0056] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an assembled well-type mold frame.

[0057] Example 1

[0058] like Figure 1 and Figure 2 As shown, the assembled well-type formwork includes welded uprights 1 and welded horizontal bars 2. A pair of parallel welded uprights 1 connected by several welded horizontal bars 2 constitute a well-type formwork component. In this application, a planar standard formwork (well-type formwork component) is used as the main body, and they are assembled into a well-shaped structural system, making each independent single-port assembled well-type formwork a spatial structure, thus improving the strength, rigidity, and stability of the assembled well-type formwork.

[0059] like Figure 3 As shown, multiple well-type mold components are horizontally assembled together by horizontal assembly connecting rods 11 to form a mold frame. The length of the mold frame can be shortened or extended according to site requirements.

[0060] A connecting component is provided at the top of the welded upright 1, which can connect the well-type formwork components upward. When it is necessary to continue to build upward, each layer is installed on the pre-installed formwork through assembly, hoisting and installation until the project needs are met.

[0061] In the technical solution of this application, the welded upright 1 and welded horizontal bar 2 are hollow rods. In practical applications, traditional coupler-type scaffolding can be modified to reuse old equipment and reduce promotion costs.

[0062] To fully utilize the advantages of assembled well-type formwork, assembled well-type formwork, either in single or multiple openings, can be continuously installed and connected to form external scaffolding, creating multiple rows of longitudinally parallel external scaffolding. In the transverse direction, they are connected together using coupler-type scaffolding to form a whole, facilitating the construction of full-span scaffolding.

[0063] At the top of the full-span scaffolding, the corresponding formwork base layer and formwork surface layer are laid, which constitutes the formwork engineering for the cast-in-place concrete floor.

[0064] Early stripping formwork heads can also be added at the top of the full-span scaffolding. The corresponding formwork base layer and formwork surface layer are laid on the early stripping formwork heads, which constitutes the early stripping formwork project for cast-in-place concrete floors, enabling flexible use.

[0065] In the construction of formwork projects for high walls and columns, an attachment climbing device is added to a special large formwork that integrates wall and column formwork, thus forming an attachment climbing formwork project and enabling cross-equipment application.

[0066] For erected scaffolding, during dismantling, it should be dismantled in the reverse direction according to the corresponding relationship during erection and installation. The dismantled multi-port assembled well-type formwork should be hoisted to the next project for installation or dismantled and loaded onto trucks and stored at designated locations on the ground. This improves transportation efficiency.

[0067] Example 2

[0068] In this embodiment, the welding pole 1 is provided with multiple horizontal assembly reinforcement positioning grooves 18, located at multiple positions on the upper, middle and lower parts of the welding pole 1.

[0069] like Figure 12 , 20 As shown in Figures 4 and 5, the horizontal assembly connecting rod 11 has connecting plates 15 at both ends. The connecting plates 15 engage with the horizontal assembly reinforcing positioning groove 18. A pair of bolts are provided on the horizontal assembly reinforcing positioning groove 18, and the connecting plates 15 have guide slots 16 that cooperate with the bolts. This double-bolt, double-slot positioning connection structure positions all bolts at the connection nodes. Tightening the bolts indicates the assembly and use working state, while loosening the bolts indicates the assembly and disassembly working state. This effectively solves the problem of separating parts from the main structure during assembly, making assembly and disassembly more convenient and faster.

[0070] During use and transportation, the nuts and bolts of the bolts do not need to be separated. The bolts are always fixed on the horizontal assembly reinforcement positioning groove 18, ensuring that spare parts are not easily lost or fallen, and further improving labor safety and production efficiency.

[0071] When in use, simply insert the connecting plate 15 into the horizontal assembly reinforcement positioning groove 18 to complete the connection. To ensure a stable connection, simply tighten the bolts.

[0072] Example 3

[0073] In this embodiment, as Figures 6-10 As shown, the connecting component is a cross-shaped positioning bolt 9, which is movably mounted on the upper node connecting plate 7. The upper node connecting plate 7 is fixed to one end of the welded upright 1.

[0074] The outer contour of the cross-shaped locating bolt 9 is tapered to facilitate guidance and docking during assembly. The cross-section is a staggered cross shape, and a limiting groove 19 is provided in the middle. The upper node connecting plate 7 is provided with a slot that mates with the cross-shaped locating bolt 9.

[0075] In use, insert the cross-shaped locating bolt 9 into the upper node connecting plate 7. When the upper node connecting plate 7 is in the limiting groove 19 position, rotate the cross-shaped locating bolt 9 to lock its position on the upper node connecting plate 7. Because of the misaligned cross shape of the cross-shaped locating bolt 9, it is not easy for it to fall off the upper node connecting plate 7 even during vibration and rotation. To further secure the cross-shaped locating bolt 9, small holes can be provided in the upper node connecting plate 7, and the cross-shaped locating bolt 9 can be connected by means of pull wire or steel wire.

[0076] Example 4

[0077] like Figure 5 , 6 As shown in Figures 12, 13, and 15, in this embodiment, a pair of connecting plates 15 are provided on the horizontal assembly connecting rod 11. A locking plate 4 is movably provided on the connecting plate 15. The locking plate 4 is connected to the connecting plate 15 through a rotating shaft. A locking head 5 is provided on the horizontal assembly reinforcing positioning groove 18. During the process of inserting the connecting plate 15 into the horizontal assembly reinforcing positioning groove 18, the locking plate 4 is lifted. After the connecting plate 15 is inserted into the horizontal assembly reinforcing positioning groove 18, the locking plate 4 is lowered. The locking head 5 blocks the locking plate 4, preventing the connecting plate 15 from being pulled out. This structure is easier to assemble. In places where the structural strength requirement is not high, the bolts of the reinforcing positioning groove 18 do not need to be tightened.

[0078] The position of the latch plate 4 can be further locked by drilling holes in the latch head 5 and inserting a pin.

[0079] Example 5

[0080] like Figure 1 , 6As shown in Figures 12, 14, 20, and 21, in this embodiment, the two ends of the welded upright 1 are respectively provided with an upper node connecting bolt reinforcing positioning groove 10 and a lower node connecting bolt reinforcing positioning groove 17, and both the upper node connecting bolt reinforcing positioning groove 10 and the lower node connecting bolt reinforcing positioning groove 17 are provided with U-shaped grooves.

[0081] The upper node connecting bolt reinforcing positioning groove 10 is rectangular, and the U-shaped groove above it extends from the upper surface to the side. The upper node connecting bolt reinforcing positioning groove 10 is provided with a bolt limiting groove 20. The connecting bolt 6 is locked in the bolt limiting groove 20, and the bolt head protrudes from the U-shaped groove.

[0082] In use, first stack and assemble the well-type formwork components. Guided by the cross-shaped locating bolt 9, assemble the upper and lower well-type formwork components together. Align the U-shaped grooves on the upper node connecting bolt reinforcing locating groove 10 and the lower node connecting bolt reinforcing locating groove 17. Slide the connecting bolt 6 upwards from the side of the upper node connecting bolt reinforcing locating groove 10 until the nut is in the lower node connecting bolt reinforcing locating groove 17, and then tighten the connecting bolt 6 to fix it. Due to the bolt limiting groove 20, the connecting bolt 6 will not rotate freely during the tightening process. At the same time, the connecting bolt 6 is always in the upper node connecting bolt reinforcing locating groove 10, so it does not need to be stored separately, and no additional bolts need to be carried during installation. This greatly reduces the labor intensity of workers and improves installation efficiency.

[0083] Example 6

[0084] like Figure 6 , 12 As shown in 13, 14, 15, and 16, in this embodiment, the reinforcing positioning groove 18 includes a fixed panel 21, an upper limit groove plate 22, and a lower limit groove plate 23. The fixed panel 21 is provided with screws that cooperate with the guide slot 16. The upper limit groove plate 22 and the lower limit groove plate 23 are located at the two ends of the fixed panel 21 and have a certain gap with the fixed panel 21. The upper limit groove plate 22 and the lower limit groove plate 23 are distributed on both sides of the fixed panel 21. The locking head 5 is provided on the lower limit groove plate 23.

[0085] A sloping liner connecting plate 3 is provided at the connection between the welded horizontal bar 2 and the welded vertical bar 1. A vertical sloping liner assembly connecting rod 8 is connected to the sloping liner connecting plate 3. A bottom support fine-tuning bolt 12 is connected to the bottom of the welded vertical bar 1.

[0086] Example 7

[0087] like Figure 20 and Figure 21 As shown, in this embodiment, the upper node connecting bolt reinforcing positioning groove 10 and the lower node connecting bolt reinforcing positioning groove 17 can be integrated with the horizontal assembly reinforcing positioning groove 18 to facilitate the improvement of strength.

[0088] Example 8

[0089] like Figure 17 As shown, in this embodiment, a closed-type fall protection safety net 13 can be hung on the welded horizontal bar 2 by means of hook-type wire binding and fixing buckle 14, which is convenient for construction and has a stable connection. Furthermore, fall protection scaffolding boards can be laid on the horizontally adjacent horizontal assembly connecting rods 11 or welded horizontal bars 2 on the installed well-type formwork, making it convenient for workers to walk.

[0090] Simultaneously, scaffolding, safety nets, and footboards are installed and positioned in one go, and then hoisted and transported in a unified manner. This improves installation efficiency and reduces safety risks during the installation process.

[0091] Example 9

[0092] like Figure 18 As shown in this embodiment, by enclosing and fixing multiple well-type formwork frames, external support can be directly provided for the pouring of columns, eliminating the need for formwork erection. Furthermore, dismantling and removal are very convenient; after disassembling the fixing connectors, the formwork can be transferred to the next process using equipment such as forklifts, pallet jacks, handcarts, and tower cranes, saving labor and time.

[0093] Example 10

[0094] like Figure 19 As shown, an extension panel 24 is fitted onto the connecting plate 7 and the cross-shaped positioning bolt 9, and is pressed together when the upper and lower well-type formwork components are assembled. The extension panel 24 is provided with bolt holes, which can laterally expand the crossbeam, facilitating engineering construction.

[0095] Example 11

[0096] like Figures 22-25 As shown, the form of the well-type formwork components can be adjusted according to the needs of the project site.

[0097] Example 12

[0098] like Figures 26-29 As shown, in this embodiment, the upper node connecting bolt reinforcing positioning groove 10 is rectangular, and the U-shaped groove above it extends from the upper surface to the side. A limiting baffle plate 101 is provided inside the upper node connecting bolt reinforcing positioning groove 10.

[0099] In this embodiment, the connecting bolt 6 is T-shaped, and a T-shaped head 61 is provided at one end of the upper node connecting bolt reinforcing positioning groove 10. The upper node connecting bolt reinforcing positioning groove 10 is located on one side of the U-shaped groove, and an L-shaped replacement baffle 102 is movably provided. The L-shaped replacement baffle 102 is fixed in the upper node connecting bolt reinforcing positioning groove 10 by screws.

[0100] In this embodiment, the L-shaped replacement baffle 102 and the limiting baffle 101 together restrict the rotation of the T-shaped head 61, preventing it from spinning freely during installation. If the connecting bolt 6 breaks, it can be replaced by removing the L-shaped replacement baffle 102.

[0101] Example 13

[0102] like Figure 30 As shown, in this embodiment, the connecting plate 7 is fixedly connected to the middle of the cross-shaped positioning bolt 9 to form a connector. In use, the connector is inserted above the welded upright 1 before being hoisted and installed. To prevent the connector from falling off, small holes can be provided in the connecting plate 7 as in embodiment 3, and the connector can be fixed to the welded upright 1 using a pull wire or steel wire.

[0103] Example 14

[0104] like Figure 31 and 32 As shown, in this embodiment, an L-shaped extension plate 25 is also included. The L-shaped extension plate 25 is provided with multiple screw holes. One side is connected to the inclined liner connecting plate 3 by screws, and the other side is connected to the vertical inclined liner assembly connecting rod 8. It can connect inclined braces between adjacent well-type mold frame components to improve the overall strength of the mold frame.
