Description

Technical Field

[0001] This application relates to the field of building construction, and particularly to a rectangular column formwork installation system and method. Background Art

[0002] As a key supporting member in building structures, the formwork installation technology of rectangular columns occupies an important position in construction projects. With the development of the construction industry, the installation efficiency of rectangular column formwork directly affects the construction progress and cost control. Therefore, optimizing the formwork installation process has become an important link in improving the efficiency of construction projects. The traditional formwork installation method is completed by manual piece-by-piece assembly. Although it can meet the basic construction requirements, its complexity limits the further improvement of construction efficiency.

[0003] Currently, the installation of rectangular column formwork mainly adopts the method of manual assembly, specifically including lifting each formwork unit to the installation position and then positioning and splicing. To ensure the precise installation of the formwork unit, it is usually necessary to use a temporary limiting device to initially position the formwork unit, and continuously adjust the position manually to ensure the splicing accuracy. In addition, there are some scenarios where mechanical auxiliary equipment is used for part of the operation, such as using a crane to lift the formwork unit to the specified height and then manually cooperating to complete the final splicing work. However, these methods still rely on a lot of manual intervention and lack efficient positioning means.

[0004] The main problem with the above traditional methods is the low installation efficiency. During the actual construction process, due to the need to repeatedly adjust the positioning and splicing of the formwork units, the construction period is extended, the labor intensity is increased, and there are also certain safety risks. This inefficient installation method can no longer meet the requirements of the modern construction industry for high-efficiency and precise construction, and there is an urgent need for a technical solution that can significantly improve the installation efficiency to solve this problem. Summary of the Invention

[0005] In order to improve the formwork installation efficiency, this application provides a rectangular column formwork installation system and method.

[0006] The rectangular column formwork installation system and method provided by this application adopt the following technical solutions: A rectangular column formwork installation system includes a suspension bracket and a number of formwork units. The suspension bracket is provided with a number of positioning members that extend vertically downward and are used for positioning the formwork units; When enclosing and splicing a number of formwork units on the same floor, the inner sides of the formwork units are positioned by abutting against the positioning members; a number of lifting mechanisms are slidably connected to the suspension bracket, and the number of lifting mechanisms corresponds one-to-one to the number of formwork units on the same floor; When splicing several template units of the upper and lower layers, the hanging bracket and the positioning member move upward synchronously, providing an installation space for several upper-layer template units to be assembled; several lifting mechanisms lift the corresponding template units to the corresponding installation height and drive the template units to move to the positioning member to complete the splicing.

[0007] By adopting the above technical solution, the setting of the hanging bracket and the positioning member can effectively improve the installation efficiency of the template units and avoid the problem of continuously adjusting the temporary limit in the traditional method. The positioning member provides a precise positioning reference for the template units, enabling the template units of the same layer to be quickly enclosed and spliced into a rectangular template frame. The combined use of the hanging bracket and the lifting mechanism realizes the efficient splicing of the upper and lower layer template units. The design of the synchronous upward movement of the hanging bracket ensures the installation space for the upper-layer template units, improving the continuity and convenience of the overall construction. The lifting mechanism lifts the template units to the corresponding height and drives them to move to the positioning member to complete the splicing, further improving the automation degree and accuracy of the installation.

[0008] Preferably, the lifting mechanism includes a sliding frame slidably connected to the hanging bracket, a lifting component arranged on the sliding frame, and a horizontal driving component installed on the hanging bracket. The lifting component is used to drive the corresponding template unit to lift and lower, and the horizontal driving component is used to drive the sliding frame to move horizontally.

[0009] By adopting the above technical solution, the sliding connection between the sliding frame and the hanging bracket enables the lifting mechanism to flexibly adjust its position. The lifting component is used to drive the template unit to lift and lower, realizing the precise positioning of the template unit in the vertical direction and improving the installation efficiency. The horizontal driving component is used to drive the sliding frame to move horizontally, enabling the template unit to accurately move to the positioning member to complete the splicing, avoiding the problem of continuously adjusting the temporary limit in the traditional method, and further improving the installation accuracy and efficiency.

[0010] Preferably, a rib structure is arranged on the top of the template unit, and a groove structure is arranged on the bottom of the template unit. The adjacent upper and lower template units are inserted and matched through the rib structure and the groove structure.

[0011] By adopting the above technical solution, a rib structure is arranged on the top of the template unit and a groove structure is arranged on the bottom. The adjacent upper and lower template units are inserted and matched through the rib structure and the groove structure, which can realize the rapid positioning and splicing of the template units and improve the installation efficiency. At the same time, this insertion and matching method can also enhance the connection stability between the upper and lower layer template units, reduce the dislocation problems that may occur during the splicing process, and thus improve the installation quality of the overall rectangular column template.

[0012] Preferably, an elastic sealing member is arranged on the inner wall of the groove structure.

[0013] By adopting the above technical solution, the setting of the elastic sealing member can effectively improve the sealing performance between the upper and lower adjacent formwork units, reduce the risk of slurry leakage during concrete pouring, and at the same time contribute to maintaining the stability of the joint of the formwork units, improving the quality and safety of the overall structure. This effect is directly generated by the technical means of adding an elastic sealing member to the inner wall of the groove structure.

[0014] Preferably, the rib structure extends along the length direction of the formwork unit. When several formwork units on the same layer are spliced, several rib structures enclose to form a rectangular ring structure.

[0015] By adopting the above technical solution, when several formwork units on the same layer are spliced, the rib structure extends along the length direction of the formwork unit and encloses to form a rectangular ring structure, forming a circular sealing belt in parallel for the upper and lower layer formworks, which is beneficial to improving the sealing effect.

[0016] Preferably, the lifting assembly includes several winches, and several winches are distributed along the length direction of the corresponding formwork unit. The traction end of the winch is detachably connected to the rib structure of the corresponding formwork unit.

[0017] By adopting the above technical solution, the lifting assembly is composed of several winches distributed along the length direction of the formwork unit, and the traction end of the winch is detachably connected to the rib structure of the formwork unit. This method can achieve precise control of the formwork unit, ensure the stability of the formwork unit during lifting through multi-point traction, and avoid tilting or damage caused by uneven single-point stress. At the same time, the detachable connection design facilitates quick replacement and adjustment, improves the installation and disassembly efficiency of the formwork unit, and further enhances the operation convenience of the entire rectangular column formwork installation system.

[0018] Preferably, the positioning member is an angle steel, and the angle steel is distributed at the inner corner position of the joint of adjacent formwork units. When the formwork unit is in place at the installation position, the inner side of the formwork unit abuts against the outer right-angle surface of the angle steel.

[0019] By adopting the above technical solution, the angle steel as the positioning member can accurately position the formwork unit. Its outer right-angle surface provides a stable support surface for the inner side of the formwork unit, ensuring that the formwork unit maintains an accurate position during splicing. The angle steel is distributed at the inner corner position of the joint of adjacent formwork units, effectively avoiding the deviation of the formwork unit during installation, improving the installation efficiency and accuracy. In addition, the structure of the angle steel is simple and easy to process, reducing the overall manufacturing cost of the system.

[0020] A method for installing a rectangular column formwork, using a rectangular column formwork installation system, includes the following steps: S1: When enclosing and splicing several formwork units on the first floor, first position the hanging bracket at the construction position of the rectangular column. The positioning member is at the corner position of the construction position of the rectangular column. Several lifting mechanisms lift the corresponding formwork units and transfer them to the outside of the positioning member. The inner sides of several formwork units are positioned by abutting against the positioning member. After several formwork units on the same layer are spliced into a rectangular formwork frame, the lifting mechanisms synchronously lower the corresponding formwork units into place and perform support and locking. S2: Disconnect the connection between the lifting mechanism and the already installed formwork unit, and then lift the entire hanging bracket to provide installation space for several formwork units on the upper layer to be assembled. The positioning member moves up synchronously with the hanging bracket, and the positioning member always abuts against the inner side of the lower layer formwork unit. The lifting mechanism lifts the formwork units to be assembled to the corresponding installation height, moves the formwork units to the positioning member for positioning, and completes the splicing work of adjacent formwork units. The lifting mechanisms synchronously lower the corresponding formwork units into place to complete the splicing work of the formwork units between the upper and lower layers. S3: Repeat step S2 until the formwork unit splicing is completed.

[0021] By adopting the above technical solution, the rectangular column formwork installation method realizes the precise positioning and rapid splicing of formwork units by using the cooperation of the hanging bracket and the positioning member. During the enclosing and splicing process of the formwork units on the first floor, the hanging bracket is positioned at the construction position, the lifting mechanisms lift the formwork units and transfer them to the outside of the positioning member, and the positioning is achieved by the abutting of the inner side of the formwork unit against the positioning member. After splicing into a rectangular formwork frame, it is lowered into place and locked. Subsequently, disconnect the connection between the lifting mechanism and the already installed formwork unit, lift the entire hanging bracket to provide installation space for the formwork units on the upper layer, and the positioning member moves up synchronously and remains in contact with the lower layer formwork unit. The lifting mechanism then lifts the formwork units to be assembled to the specified height, moves them to the positioning member to complete positioning and splicing, and finally synchronously lowers them into place. Repeat this process until all formwork units are spliced, thereby significantly improving the installation efficiency, reducing the adjustment time, and ensuring the splicing accuracy.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the cooperation of the hanging bracket and the positioning member, the formwork units can be quickly positioned during the splicing process, reducing the need for manual repeated adjustment and significantly improving the installation efficiency of the rectangular column formwork. 2. The coordinated action of the hanging bracket and the lifting mechanism enables the assembly of the formwork units between the upper and lower layers to proceed orderly, avoiding the operation difficulties caused by insufficient space in the traditional method and further improving the construction efficiency. 3. The positioning member provides a precise positioning reference for the formwork units, ensuring the splicing accuracy, reducing the construction error, and improving the quality and stability of the overall formwork installation.

[0029] The following further Figures 1-5 elaborates on the present application with reference to the attached drawings.

[0030] An embodiment of the present application discloses a rectangular column formwork installation system. Referring to Figure 1 and Figure 2 , it includes a hanging bracket 1 and several formwork units 2. Among them, several positioning members 4 that extend vertically downward and are used for positioning the formwork units 2 are welded and fixed below the hanging bracket 1. When enclosing and splicing several formwork units 2 on the same layer, the inner sides of several formwork units 2 are positioned by abutting against the positioning members 4. Several lifting mechanisms 3 are slidably connected above the hanging bracket 1, and several lifting mechanisms 3 correspond one - to - one with several formwork units 2 on the same layer; when splicing several formwork units 2 of the upper and lower layers, the hanging bracket 1 and the positioning members 4 move upward synchronously to provide an installation space for several upper - layer formwork units 2 to be assembled. Several lifting mechanisms 3 lift the corresponding formwork units 2 to the corresponding installation height and drive the formwork units 2 to move to the positioning members 4 to complete the splicing, which is beneficial to improving the installation efficiency of the formwork units 2.

[0031] The top of the template unit 2 is provided with a rib structure 21 protruding therefrom, and the bottom of the template unit 2 is provided with a groove structure 22. The adjacent upper and lower template units 2 are plugged and matched through the rib structure 21 and the groove structure 22. The rib structure 21 extends along the length direction of the template unit 2 and is made of high-strength steel, having good bending resistance. An elastic sealing member is adhered to the inner wall of the groove structure 22, which can be a rubber strip or a silica gel strip, to ensure the sealing between the template units 2 and prevent slurry leakage during the concrete pouring process. When a plurality of template units 2 on the same layer are spliced, a plurality of rib structures 21 enclose to form a rectangular ring structure, which cooperates with the groove and the elastic sealing member at the bottom of the upper template unit 2, so as to form an annular sealing belt at the assembly gap between the upper and lower template units 2, thereby improving the overall sealing effect of the template.

[0032] The hanger 1 includes a rectangular main frame and a suspension rope, and the whole hanger 1 is lifted by a crane. The main frame is made of high-strength steel and is in a rectangular structure as a whole, capable of withstanding large tensile and compressive forces. The positioning member 4 is an angle steel, which is distributed at the inner corner positions of the splicing joints of adjacent template units 2. In addition, the inner right-angle surface of the angle steel faces the inside of the rectangular column construction position. When the template unit 2 is in place at the installation position, the inner side of the template unit 2 abuts against the outer right-angle surface of the angle steel. In addition, a metal sheet or a rubber pad with elastic buffering function can be covered on the outer side of the positioning member 4 to avoid damage to the template unit 2 caused by collision during the installation process.

[0033] In this embodiment, the lifting mechanism 3 includes a sliding frame 32 slidably connected to the hanger 1, and a lifting assembly 33 and a horizontal driving assembly 31 installed on the sliding frame 32. The sliding frame 32 is made of aluminum alloy profiles, having the characteristics of being light and strong. The lifting assembly 33 is used to drive the corresponding template unit 2 to lift and lower. Specifically, the lifting assembly 33 includes a plurality of winches, and the winches are spaced along the length direction of the corresponding template unit 2 on the sliding frame 32. The traction end of the winch is detachably connected by hooking and locking with the hoisting hole of the rib structure 21, and the winch drives the template unit 2 to move up and down through a steel wire rope.

[0034] The horizontal driving assembly 31 is used to drive the sliding frame 32 to move horizontally. A lead screw transmission mechanism, an electric push rod or a gear-rack transmission mechanism can be adopted. Among them, the electric push rod can drive the sliding frame 32 to move horizontally through telescopic action, and the gear-rack transmission mechanism drives the gear to rotate through a motor, thereby driving the rack and the sliding frame 32 to horizontally displace. The horizontal driving assemblies 31 of the four lifting mechanisms 3 of the formwork installation system are respectively arranged horizontally and vertically at the two center lines of the hanger 1, and the extending directions all face the center of the hanger 1, so as to facilitate the corresponding template unit 2 to stably gather towards the center of the hanger 1 and be able to reach the positioning member 4 at the same time for installation.

[0035] The implementation principle of this embodiment is as follows: The preliminary positioning of the formwork unit 2 is achieved through the positioning member 4 on the hanging bracket 1, avoiding the process of manual repeated adjustment and significantly improving the installation efficiency. The setting of the lifting mechanism 3 makes the lifting and horizontal movement of the formwork unit 2 more precise, reduces manual intervention, and lowers the construction risk. At the same time, the insertion design between the formwork units 2 not only enhances the connection strength but also improves the sealing and safety of the system through the elastic sealing member.

[0036] This embodiment provides a method for installing a rectangular column formwork, including the following steps: S1: As Figure 1 and Figure 3 shown, when enclosing and splicing several formwork units 2 on the first floor, first position the hanging bracket 1 at the construction position of the rectangular column, with the positioning member 4 located at the corner position of the rectangular column construction position. The winches of several lifting mechanisms 3 simultaneously lift the corresponding formwork units 2, and drive the sliding frame 32 to move towards the center of the hanging bracket 1 through the horizontal driving member, so as to translate the formwork unit 2 to the outside of the positioning member 4. The inner sides of several formwork units 2 are positioned by abutting against the positioning member 4. After several formwork units 2 on the same layer are spliced into a rectangular formwork frame, the winch releases the traction rope, synchronously lowers the corresponding formwork unit 2 into place, and performs support and locking.

[0037] S2: As Figure 4 and Figure 5 shown, disconnect the connection between the lifting mechanism 3 and the formwork unit 2 that has been put in place, that is, separate the hook of the traction rope from the hanging hole of the rib structure 21. Then the crane lifts the hanging bracket 1 as a whole to provide an installation space for several formwork units 2 of the upper layer to be assembled. The positioning member 4 moves up synchronously with the hanging bracket 1 into place. The lifting mechanism 3 lifts the formwork unit 2 to be assembled to the corresponding installation height, moves the formwork unit 2 to the positioning member 4 for positioning, and completes the splicing work of adjacent formwork units 2. The lifting mechanism 3 synchronously lowers the corresponding formwork unit 2 into place to complete the splicing work of the formwork units 2 of the upper and lower layers. It should be emphasized that during the lifting process of the hanging bracket 1 of the positioning member 4, the installation and positioning process of the upper layer formwork unit 2, and the process of lowering the upper layer formwork unit 2 into place, the positioning member 4 always abuts against the inner side of the lower layer formwork unit 2, which is beneficial to improving the installation accuracy and efficiency of the formwork unit 2.

[0038] S3: Repeat step S2 until all formwork units 2 are spliced.

[0039] The implementation principle of this embodiment is as follows: Through the method of gradually splicing in layers, combined with the coordinated operation of the hanging bracket 1 and the lifting mechanism 3, the efficient installation of the formwork unit 2 is realized. The method is simple and easy to implement, with standardized operations, which can effectively shorten the construction period, reduce the labor intensity, and improve the construction safety and accuracy.

[0040] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
