Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a rapid turnover construction method for aluminum-wood composite high-rise buildings. Background Technology

[0002] As building shapes and structures become increasingly diverse, construction often requires the creation of various forms and / or corresponding changes in the vertical structural cross-section based on different heights. When a building has many floors, aluminum formwork systems are more economical, and aluminum formwork allows for rapid turnover, making it a better choice from both an economic and on-site construction period perspective. However, when there are many variations in cross-section, aluminum formwork systems cannot meet the construction requirements, necessitating the selection of wooden formwork systems.

[0003] Since vertical timber formwork systems typically require replacement every six floors, and horizontal structures require three sets of formwork to ensure turnover, this results in material waste and is uneconomical. Therefore, there is a need to provide a rapid turnover construction method for high-rise buildings using an aluminum-timber composite system, which can solve the problem of uneconomical construction using existing timber formwork systems. Summary of the Invention

[0004] The purpose of this invention is to provide a rapid turnover construction method for aluminum-wood combination in high-rise buildings, which can solve the problem of uneconomical construction of wood formwork systems in the prior art.

[0005] This invention is implemented as follows:

[0006] A rapid turnover construction method for aluminum-wood composite high-rise buildings includes the following steps:

[0007] Step 1: Measure and lay out the dimensions according to the building structure drawings, and configure the vertical wooden formwork and horizontal aluminum formwork;

[0008] Step 2: After the concealed works of vertical reinforcement are inspected and accepted, the construction of the vertical wooden formwork for the vertical structure is carried out;

[0009] Step 3: After the vertical wooden formwork is completed, the horizontal aluminum formwork for the horizontal structural beams and floor slabs is constructed.

[0010] Step 4: Connect and fix the vertical wooden formwork and the horizontal aluminum formwork to form a whole with the vertical and horizontal formwork;

[0011] Step 5: Adjust the vertical and horizontal elevation of the vertical wooden formwork and the horizontal aluminum formwork. After the upper reinforcement is constructed and inspected, pour the concrete.

[0012] Step 6: After the concrete reaches a certain strength, remove the vertical wooden formwork and horizontal aluminum formwork, retain the uprights, and rotate the vertical wooden formwork and horizontal aluminum formwork upwards.

[0013] In step 2, vertical timbers are set as secondary keels on the outside of the vertical timber formwork, and horizontal double steel pipes are set as main keels on the outside of the vertical timbers. The vertical timber formwork and horizontal double steel pipes on both sides of the vertical structure are tied and reinforced by tie bolts.

[0014] Step 3 includes the following sub-steps:

[0015] Step 3.1: Install support rods below the horizontal structural beams and floor slabs;

[0016] Step 3.2: Lay a horizontal aluminum formwork above the uprights.

[0017] The horizontal aluminum formwork includes several unit aluminum formworks, which are spliced ​​and fixed together with adjacent unit aluminum formworks, and the unit aluminum formworks located above the uprights are connected to the uprights through top supports.

[0018] The top support is installed below the joint of two adjacent unit aluminum templates. The upper end of the top support is fixedly connected to the unit aluminum template, and the lower end of the top support is matched and inserted into the top of the upright.

[0019] When laying the horizontal aluminum formwork for the horizontal structural beam, first lay the bottom unit aluminum formwork of the horizontal structural beam, and then lay the side unit aluminum formwork of the horizontal structural beam. The side unit aluminum formwork is connected and fixed to the bottom unit aluminum formwork of the floor slab by angle aluminum and pins.

[0020] Step 4 includes the following sub-steps:

[0021] Step 4.1: Fix wooden beams on the outside of the vertical wooden formwork, with the wooden beams lower than the corner aluminum of the horizontal aluminum formwork;

[0022] Step 4.2: Install a second U-shaped steel bar on the timber, so that the second U-shaped steel bar is arranged around the top, bottom and outside of the timber;

[0023] Step 4.3: Install a first U-shaped steel between the top of the timber and the angle aluminum, such that the top of the first U-shaped steel abuts against the bottom surface of the angle aluminum, the bottom of the first U-shaped steel abuts against the top surface of the timber, and the side of the first U-shaped steel abuts against the outer surface of the vertical timber formwork.

[0024] Step 4.4: Press the top of the second U-shaped steel against the bottom of the first U-shaped steel, and press the bottom of the second U-shaped steel against the bottom surface of the timber;

[0025] Step 4.5: Connect and fix the top of the first U-shaped steel to the angle aluminum.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] 1. This invention incorporates both horizontal aluminum formwork and vertical wooden formwork, employing a combination of aluminum and wood in high-rise buildings. The aluminum formwork is used in the horizontal structure, while the wooden formwork is used in the variable vertical structure. This fully leverages the advantages of both aluminum and wood formwork, solving the problem of high costs caused by using only wooden formwork for multiple changes in the vertical structure. It can reduce construction costs while ensuring construction quality.

[0028] 2. The present invention has a first U-shaped steel and a second U-shaped steel. The first U-shaped steel and the second U-shaped steel are reinforced by bolts and connected to form a whole with the horizontal aluminum formwork and the vertical wooden formwork. This improves the structural integrity and stability of the formwork, facilitates the quick disassembly of the horizontal aluminum formwork and the vertical wooden formwork, improves the turnover rate of the formwork, eliminates the need to prepare 3 sets of horizontal wooden formwork system, helps to speed up the construction period and improve economic benefits.

Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] Please see the appendix Figure 1 and attached Figure 2 A rapid turnover construction method for aluminum-wood composite high-rise buildings includes the following steps:

[0034] Step 1: Measure and lay out the dimensions according to the building structure drawings, and configure the vertical wooden formwork 21 and the horizontal aluminum formwork 1.

[0035] Based on the structural elements of the building, such as walls, columns, beams, and floor slabs, the vertical wooden formwork 21 and the horizontal aluminum formwork 1 are rationally configured. The vertical wooden formwork 21 is used for the construction of vertical structures 32 such as walls and columns to meet the requirements of varying vertical cross sections. The horizontal aluminum formwork 1 is used for the construction of horizontal structures such as beams and floor slabs, and can achieve quick dismantling of the formwork for horizontal structures, which is conducive to accelerating the construction period and improving economic efficiency.

[0036] Step 2: After the concealed works of vertical reinforcement are inspected and accepted, the construction of vertical wooden formwork 21 for vertical structure 32 is carried out.

[0037] In step 2, vertical timber slats 2 are set on the outside of the vertical timber formwork 21 as secondary keels, and horizontal double steel pipes 23 are set on the outside of the vertical timber slats 2 as main keels. The vertical timber formwork 21 and horizontal double steel pipes 23 on both sides of the vertical structure 32 are tied and reinforced by tie bolts 22.

[0038] The quantity and spacing of the vertical timber 2 and the horizontal double steel pipes 23 can be adjusted according to the size of the vertical timber formwork 21 and the actual support requirements. The vertical timber formwork 21 includes the bottom formwork and the formwork on both sides. It is supported by conventional process and the formwork on both sides can be fixed by tie rods 22.

[0039] Step 3: After the vertical wooden formwork 21 is completed, the horizontal aluminum formwork 1 for the horizontal structural beams 31 and floor slabs 3 is constructed.

[0040] Step 3 includes the following sub-steps:

[0041] Step 3.1: Place support rods 13 below the horizontal structural beam 31 and the floor slab 3.

[0042] Round steel pipes can be connected by means of disc buckles or other methods to support the bottom of the horizontal aluminum formwork 1 on the horizontal structural beam 31 and floor slab 3, forming a vertical support system; the number and spacing of the vertical poles 13 can be adjusted according to the actual support requirements.

[0043] Step 3.2: Lay horizontal aluminum formwork 1 above the upright 13.

[0044] The horizontal aluminum formwork 1 includes several unit aluminum formworks. Adjacent unit aluminum formworks are spliced ​​and fixed together by pins, and the unit aluminum formwork located above the upright 13 is connected to the upright 13 by the top support 12.

[0045] Unit aluminum formwork can be standardized and customized. It uses pins for easy splicing and disassembly, enabling quick disassembly and turnover of horizontal structure formwork, which helps to speed up the construction period and can also meet the formwork support requirements of various types of horizontal structures.

[0046] The top support 12 is set below the splice of two adjacent unit aluminum templates. The upper end of the top support 12 is fixedly connected to the unit aluminum template by a pin, and the lower end of the top support 12 is matched and inserted into the top of the upright 13.

[0047] Preferably, the top support 12 can be made of round steel pipe, with a specification slightly smaller than that of the upright 13. The top support 12 can be inserted into the upright 13 to support the aluminum formwork unit. The insertion is stable and can bear the weight of the floor slab 3 and the horizontal structural beam 31, ensuring the stability of the horizontal structure and the horizontal aluminum formwork 1.

[0048] When laying the horizontal aluminum formwork 1 of the horizontal structural beam 31, the bottom unit aluminum formwork of the horizontal structural beam 31 is laid first, and then the side unit aluminum formwork of the horizontal structural beam 31 is laid. The side unit aluminum formwork is connected and fixed to the bottom unit aluminum formwork of the floor slab 3 by angle aluminum and pins.

[0049] The horizontal aluminum formwork 1 of the horizontal structural beam 31 and the horizontal aluminum formwork 1 of the floor slab 3 are connected as a whole by angle aluminum and pins, which facilitates the synchronous pouring of concrete for the horizontal structural beam 31 and the floor slab 3, and helps to improve the integrity, structural strength and load-bearing capacity of the horizontal structure formwork.

[0050] Step 4: Connect and fix the vertical wooden formwork 21 and the horizontal aluminum formwork 1 so that the vertical structure 32 and the horizontal structure formwork are connected to form a whole, and the vertical wooden formwork 21 can also provide support for the horizontal aluminum formwork 1.

[0051] Please see the appendix Figure 2 Step 4 includes the following sub-steps:

[0052] Step 4.1: Fix wooden beams 42 on the outside of the vertical wooden formwork 21 with iron nails 44. The wooden beams 42 are lower than the corner aluminum 11 of the horizontal aluminum formwork 1.

[0053] The number of nails 44 can be adjusted according to the size of the timber 42. The nails 44 are used to connect and fix the vertical wooden template 21 to the timber 42.

[0054] Step 4.2: Install a second U-shaped steel 43 on the timber 42, so that the second U-shaped steel 43 is arranged around the top, bottom and outside of the timber 42.

[0055] The second U-shaped steel 43 is used to fix the first U-shaped steel 41 to be installed later by means of abutment and compression. It is easy to disassemble and assemble, and has high installation stability.

[0056] Step 4.3: Set a first U-shaped steel 41 between the top of the timber 42 and the angle aluminum 11, so that the top of the first U-shaped steel 41 abuts against the bottom surface of the angle aluminum 11, the bottom of the first U-shaped steel 41 abuts against the top surface of the timber 42, and the side of the first U-shaped steel 41 abuts against the outer surface of the vertical wooden template 21.

[0057] The first U-shaped steel 41 is used to attach to the top surface of the timber 42, the bottom surface of the angle aluminum 11, and the outer surface of the vertical timber template 21, thereby improving the connection reliability between the angle aluminum 11 and the vertical timber template 21 and preventing the connection nodes from shaking or loosening.

[0058] Step 4.4: Press the top of the second U-shaped steel 43 against the bottom of the first U-shaped steel 41, and tighten the bottom of the second U-shaped steel 43 against the bottom surface of the wooden beam 42 with bolts.

[0059] Preferably, a screw hole is pre-drilled at the bottom of the second U-shaped steel 43. The bolt is screwed into the screw hole at the bottom of the second U-shaped steel 43 and pressed against the bottom surface of the timber 42, providing a downward reaction force to the top surface of the second U-shaped steel 43. This causes the top of the second U-shaped steel 43 to press the bottom of the first U-shaped steel 41 against the timber 42, thereby fixing the timber 42 and the vertical wooden template 21 relatively.

[0060] Step 4.5: Connect and fix the top of the first U-shaped steel 41 to the angle aluminum 11 using pin 4.

[0061] The first U-shaped steel 41 is fixed to the horizontal aluminum template 1 by pin 4 and angle aluminum 11, so that the first U-shaped steel 41 and the second U-shaped steel 43 are easy and quick to assemble and disassemble, which facilitates the rapid assembly and disassembly of the horizontal aluminum template 1 and helps to improve the turnover rate.

[0062] Step 5: Adjust the vertical and horizontal elevation of the vertical wooden formwork 21 and the horizontal aluminum formwork 1. After the upper reinforcement is constructed and inspected, pour concrete.

[0063] The reinforcement work and concrete pouring can be carried out using conventional methods, which will not be elaborated here.

[0064] Step 6: After the concrete reaches a certain strength, remove the vertical wooden formwork 21 and the horizontal aluminum formwork 1, retain the uprights 13, and rotate the vertical wooden formwork 21 and the horizontal aluminum formwork 1 upwards.

[0065] The uprights 13 provide support for the floor slab 3 and the horizontal structural beams 31, ensuring the safety of the horizontal structure. This facilitates the upward and downward turnover of the vertical wooden formwork 21 and the horizontal aluminum formwork 1, solving the problem of needing to prepare 3 sets of horizontal wooden formwork systems to ensure the construction turnover of the horizontal structure. This helps to control construction costs and improve economic efficiency.

[0066] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the invention. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
