Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic climbing formwork construction, and specifically relates to a hydraulic climbing formwork construction method for a multi-opening wall. Background Art

[0002] With the continuous progress of modern construction technology, the hydraulic climbing formwork, as an efficient and safe construction method, has been widely used in the construction of high-rise and super-high-rise buildings. The hydraulic climbing formwork technology has been favored by the construction industry for its unique advantages, such as fast construction speed, high formwork utilization rate, and simple operation.

[0003] The basic principle of the hydraulic climbing formwork system is that through the lifting action of hydraulic jacks, the formwork system climbs up and down along the pre-installed guide rails. This technology effectively reduces the number of formwork disassembly and installation times and improves the construction efficiency. However, in actual operation, the openings on the wall pose quite a challenge to the installation, climbing, and stability of the climbing formwork. The openings on the wall will break the continuity of the formwork, making it impossible to install the wall-attached seat, which has a great impact on the use of the hydraulic climbing formwork system. This results in the use of traditional formwork support methods during the construction of walls with more openings, leading to a decrease in construction efficiency. Summary of the Invention

[0004] The embodiment of the present invention provides a hydraulic climbing formwork construction method for a multi-opening wall to solve the above problems.

[0005] A hydraulic climbing formwork construction method for a multi-opening wall includes the following steps:

[0006] Determine the positions of all the openings on the wall according to the construction parameters of the building to obtain the opening distribution position parameters;

[0007] Using the opening distribution position parameters, calculate the fixed positions of the load-bearing triangular brackets in the hydraulic climbing formwork system; and at least one floating position; and the installation positions of the wall-attached seats corresponding to the fixed positions or floating positions;

[0008] Set the load-bearing triangular brackets in the hydraulic climbing formwork system using the obtained fixed positions and floating positions; and set the climbing formwork embedded parts during the pouring process according to the installation positions of the wall-attached seats;

[0009] During the climbing formwork process, according to the positions of the openings, select to use the load-bearing triangular brackets at the fixed positions and / or floating positions as the climbing positions, and at the same time adjust the positions of the guide rails according to the climbing positions;

[0010] When neither the above fixed position nor the floating position can avoid the openings on the wall, fabricate auxiliary support steel columns and install them at the openings as the attachment structure of the wall-attached seat, and at the same time set structures that can be connected to the wall-attached seat on the auxiliary support steel columns according to the obtained installation positions of the wall-attached seats;

[0011] Use the climbing formwork structure set above to carry out climbing formwork construction on the building.

[0012] Furthermore, the steps to determine the wall openings are as follows:

[0013] Construct a corresponding model of the building according to the construction parameters of the building;

[0014] Identify the position parameters of the openings on the building wall according to the constructed building model;

[0015] Obtain the opening distribution position parameters based on the position parameters of all the openings.

[0016] Furthermore, the fixed position is defined as the position where the load-bearing triangular bracket is fixedly installed in the hydraulic climbing formwork system, and among them, the fixed position is connected to the attached wall seat at its corresponding position.

[0017] Furthermore, the floating position is defined as the position where the load-bearing triangular bracket is movably installed in the hydraulic climbing formwork system, and among them, the floating position is connected to the attached wall seat at its corresponding position.

[0018] Furthermore, the way that the load-bearing triangular bracket is installed at the floating position in the hydraulic climbing formwork system is as follows:

[0019] Set slide rails respectively in the transverse direction of the upper and lower platforms of the climbing layer of the hydraulic climbing formwork system;

[0020] Set a load-bearing triangular bracket that can slide and be fixed on the above-mentioned slide rails;

[0021] During the construction process, when selecting the floating position, move the load-bearing triangular bracket set on the above-mentioned slide rails to the floating position and then fix its position.

[0022] Furthermore, the steps to calculate the fixed position and floating position of the load-bearing triangular bracket in the hydraulic climbing formwork system by using the opening distribution position parameters are as follows:

[0023] Use the building model and the opening distribution position parameters to mark the area avoiding the openings;

[0024] According to the marked area, analyze and obtain the fixed position and floating position of the load-bearing triangular bracket and their usage cooperation relationship;

[0025] At the same time, conduct a stress simulation analysis on the hydraulic climbing formwork system according to the above fixed position and floating position and their usage cooperation relationship to verify the fixed position and floating position;

[0026] If the verification passes, obtain the fixed position and floating position. If the verification fails, adjust the fixed position until the fixed position and floating position pass the verification.

[0027] Further, the preferred order of the usage and cooperation relationships of the fixed positions or floating positions obtained by calculation is as follows: 1. Only use the fixed positions; 2. Use the fixed positions and floating positions simultaneously, and the quantity ratio of the fixed positions is greater than two-thirds; 3. Use the fixed positions and floating positions simultaneously, and the quantity ratio of the fixed positions is less than two-thirds; 4. Only use the floating positions.

[0028] Further, when moving the guide rail on the fixed-position wall attachment to the floating-position wall attachment, the tower crane method is adopted to hoist the fixed-position guide rail to the floating-position wall attachment.

[0029] Further, a hoisting device is provided on the hydraulic climbing formwork system. When moving the guide rail on the fixed-position wall attachment to the floating-position wall attachment, the hoisting device is used to hoist the fixed-position guide rail to the floating-position wall attachment.

[0030] Further, the hoisting device is movably arranged on the hydraulic climbing formwork system, and the position of the hoisting device can be moved according to the hoisting position.

[0031] The beneficial effects of the above technical solutions provided by the embodiments of the present invention at least include:

[0032] When the present invention constructs a multi-opening wall, it can set fixed positions and floating positions according to the positions of the openings to avoid the opening areas as much as possible, ensure the normal use of the hydraulic climbing formwork system during the construction of the multi-opening wall, and improve the construction efficiency of the multi-opening wall.

[0040] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be completely conveyed to those skilled in the art.

[0041] As Figure 1 shown, it is a schematic flow chart of the hydraulic climbing formwork construction method for a multi-opening wall disclosed in an embodiment of the present invention, including the following steps:

[0042] S1. Determine the positions of all openings on the wall according to the construction parameters of the building to obtain the opening distribution position parameters;

[0043] Among them, the steps for determining the wall openings are as follows:

[0044] S11. Construct a model of the corresponding building according to the construction parameters of the building;

[0045] S12. Identify the position parameters of the openings on the building wall according to the constructed building model;

[0046] S13. Obtain the opening distribution position parameters according to the position parameters of all the openings.

[0047] S2. Use the opening distribution position parameters to calculate the fixed positions of the load-bearing triangular brackets in the hydraulic climbing formwork system; and at least one floating position; and the installation positions of the wall-mounted seats corresponding to the fixed positions or floating positions;

[0048] Among them, the definitions of the above-mentioned fixed position and floating position are:

[0049] 1. The fixed position is defined as the position where the load-bearing triangular bracket is fixedly installed in the hydraulic climbing formwork system, and among them, the fixed position is connected to the wall-mounted seat at its corresponding position.

[0050] 2. The floating position is defined as the position where the load-bearing triangular bracket is movably installed in the hydraulic climbing formwork system, and among them, the floating position is connected to the wall-mounted seat at its corresponding position.

[0051] Combined with Figure 2Schematic diagram of the structure of the existing hydraulic climbing formwork system shown. A hydraulic climbing structure is provided at the load-bearing triangular support. The hydraulic climbing structure is connected to the guide rail installed on the wall. During the climbing process, the hydraulic climbing structure drives the whole to lift upward along the guide rail. In the prior art, the load-bearing triangular support and the installed hydraulic climbing mechanism are set at fixed positions. This results in that during the climbing process, if there is an opening on the wall and the position of the opening coincides with that of the guide rail, the attachment seat connecting the guide rail to the wall cannot be installed, causing the climbing formwork process to malfunction.

[0052] In order to better solve this problem, according to the construction parameters, the present invention obtains the position parameters of the distribution of all openings, and calculates the fixed positions and floating positions of the load-bearing triangular supports in the hydraulic climbing formwork system based on the position parameters of the distribution of the openings. The specific steps are as follows:

[0053] S21, using the model of the building and the position parameters of the distribution of the openings, mark the area avoiding the openings;

[0054] S22, based on the marked area, analyze and obtain the fixed positions and floating positions of the load-bearing triangular supports and their usage cooperation relationships;

[0055] S23, at the same time, according to the above fixed positions and floating positions and their usage cooperation relationships, conduct a force simulation analysis on the hydraulic climbing formwork system to verify the fixed positions and floating positions;

[0056] S24, if the verification passes, obtain the fixed positions and floating positions; if the verification fails, adjust the fixed positions until the fixed positions and floating positions pass the verification.

[0057] During the setting process of the above calculated fixed positions and floating positions, the preferred order of the usage cooperation relationships is as follows: 1. Only use the fixed positions; 2. Use the fixed positions and floating positions simultaneously, and the proportion of the number of fixed positions is greater than two-thirds; 3. Use the fixed positions and floating positions simultaneously, and the proportion of the number of fixed positions is less than two-thirds; 4. Only use the floating positions.

[0058] It should be noted that the cooperation relationship refers to the cooperation relationship between the fixed positions and floating positions set for each floor during the building construction process, that is, the comparison of the number of fixed positions and the number of floating positions for each floor. When the fixed positions can cover the entire construction process, the fixed positions are preferred.

[0059] It should be noted that after the fixed position and the floating position are allocated, the position of the load-bearing triangular bracket at the fixed position in the hydraulic climbing formwork system remains constant from the start to the end of the construction. The position of the load-bearing triangular bracket at the floating position in the hydraulic climbing formwork system is dynamically adjusted according to the calculated position during the construction process from the start to the end, so that the hydraulic climbing formwork system can work properly.

[0060] The advantage of using the fixed position and the floating position is that the calculated fixed position and floating position can avoid the opening position as much as possible from the start to the end of the construction, and can achieve as much as possible to maintain the construction smoothness and keep the normal operation of the construction when carrying out hydraulic climbing formwork construction on the multi-opening wall.

[0061] S3. Set the load-bearing triangular brackets in the hydraulic climbing formwork system using the obtained fixed position and floating position; and set the climbing formwork embedded parts during the pouring process according to the installation position of the wall attachment seat;

[0062] It should be noted that the climbing formwork embedded parts are poured into the wall body for installing the wall attachment seat, and hydraulic climbing structures are set on both the load-bearing triangular brackets at the fixed position and the floating position.

[0063] Among them, the way of installing the load-bearing triangular bracket at the floating position in the hydraulic climbing formwork system is as follows:

[0064] Sliding rails are respectively set in the transverse direction of the upper and lower platforms of the climbing layer of the hydraulic climbing formwork system;

[0065] A load-bearing triangular bracket that can slide and be fixed on the above-mentioned sliding rail is set on the sliding rail;

[0066] During the construction process, when selecting the floating position, move the load-bearing triangular bracket set on the above-mentioned sliding rail to the floating position and then fix its position.

[0067] The above-mentioned load-bearing triangular bracket can be fixed on the sliding rail by using snap fixation, bolt fixation and other fixation methods. When it needs to be moved, after loosening the fixing structure, the load-bearing triangular bracket can move freely on the sliding rail.

[0068] S4. During the climbing formwork process, according to the position of the opening, select to use the load-bearing triangular brackets at the fixed position and / or the floating position as the climbing position, and at the same time adjust the position of the guide rail according to the climbing position.

[0069] In an example, there is an opening above the fixed position a, a wall above the fixed position b, and a wall above the floating position a. According to the cooperation of the calculated fixed position and floating position, at this time, the floating position a and the fixed position b are used in cooperation. The steps are as follows:

[0070] Lift the guide rail at the fixed position a from the wall-attached seat at the fixed position a to the wall-attached seat at the floating position a. During the climbing process, use the load-bearing triangular brackets at the floating position a and the fixed position b as the climbing positions to drive the whole to climb upward to the predetermined position.

[0071] It should be noted that sufficient climbing formwork embedded parts are pre-embedded in the vertical wall at the floating position a. After installing the wall-attached seat on the embedded parts, when lifting the guide rail from the wall-attached seat at the fixed position a to the wall-attached seat at the floating position a, the guide rail can be lifted from the current floor height to the upper predetermined position, achieving the effect of driving the whole to climb upward to the predetermined position.

[0072] In another example, there are openings above the fixed position a and the fixed position b, and the upper part of the floating position a and the floating position b is a wall. According to the calculated cooperation of the fixed position and the floating position, at this time, the floating position a and the floating position b are used in cooperation. The steps are as follows:

[0073] Lift the guide rails at the fixed position a and the fixed position b from the wall-attached seats at the fixed position a and the fixed position b to the wall-attached seats at the floating position a and the floating position b respectively. During the climbing process, use the load-bearing triangular brackets at the floating position a and the floating position b as the climbing positions to drive the whole to climb upward to the predetermined position.

[0074] It should be noted that sufficient climbing formwork embedded parts are pre-embedded in the vertical walls at the floating position a and the floating position b. After installing the wall-attached seats on the embedded parts, when lifting the guide rails from the wall-attached seats at the fixed position a and the fixed position b to the wall-attached seats at the floating position a and the floating position b, the guide rails can be lifted from the current floor height to the upper predetermined position, achieving the effect of driving the whole to climb upward to the predetermined position.

[0075] S5. When the openings on the wall cannot be avoided at the above fixed positions or floating positions, fabricate auxiliary support steel columns and install them at the openings as the attachment structure of the wall-attached seat. At the same time, set up a structure that can be connected to the wall-attached seat on the auxiliary support steel column according to the obtained installation position of the wall-attached seat;

[0076] In one example, there are openings above the fixed position a, the fixed position b, the floating position a, and the floating position b. According to the calculated cooperation of the fixed position and the floating position, the fixed position a and the fixed position b are used in cooperation. The steps are as follows:

[0077] Set up auxiliary support steel columns at the openings. At the same time, set up a structure connected to the wall-attached seat on the auxiliary support steel column according to the calculated position, and install the wall-attached seat;

[0078] Lift the guide rails at the fixed position a and the fixed position b to the wall-attached seats on the auxiliary support steel columns;

[0079] Use the load-bearing triangular brackets at the fixed positions a and b as the climbing positions, and drive the whole to climb upward to the predetermined position.

[0080] S6. Use the climbing formwork structure set above to carry out climbing formwork construction on the building.

[0081] In the above S4 - S5, when moving the guide rail on the fixed-position wall attachment base to the floating-position wall attachment base, use a tower crane to hoist the fixed-position guide rail to the floating-position wall attachment base, or a hoisting device is provided on the hydraulic climbing formwork system. When moving the guide rail on the fixed-position wall attachment base to the floating-position wall attachment base, use the hoisting device to hoist the fixed-position guide rail to the floating-position wall attachment base. Among them, the hoisting device is movably arranged on the hydraulic climbing formwork system and can move the position of the hoisting device according to the hoisting position. After adjusting to the predetermined position, the position of the hoisting device can be fixed.

[0082] When the present invention constructs a multi-opening wall, it can set the fixed position and the floating position according to the position of the opening to avoid the opening area as much as possible, ensure the normal use of the hydraulic climbing formwork system during the construction of the multi-opening wall, and improve the construction efficiency of the multi-opening wall.
