Description

Technical Field

[0001] This invention relates to the technical field of formwork support systems for building construction, and in particular to an adjustable composite slab formwork support device and construction method. Background Technology

[0002] With the rise and development of prefabricated buildings, precast components (such as precast walls, precast composite slabs, and precast stairs) are being used extensively in building construction. Simultaneously, modular scaffolding, with its high load-bearing capacity and ease of installation, is also being applied in building projects. However, during on-site construction, irregular joints such as the junction of composite slabs and walls often fail to conform to modular dimensions, making it impossible to install modular scaffolding uprights. Without a modular scaffolding system, grout leakage or even formwork bulging at the junction of the composite slab and wall can occur, affecting floor height. Adding coupler scaffolding, on the other hand, can lead to mixed materials and inconvenience in maintenance. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention provides an adjustable composite slab formwork support device and construction method.

[0004] In a first aspect, the present invention provides an adjustable composite slab formwork support device, comprising a horizontally arranged scaffolding steel pipe, one end of which is fixed to an upright of an adjacent formwork support system by a right-angle coupler, and the other end of which is vertically fixed to a channel steel, and the top of which is fixed to a horizontally arranged angle steel for supporting the formwork.

[0005] Preferably, the scaffolding steel pipes are φ48.3×3.6 standard scaffolding steel pipes.

[0006] Preferably, the scaffolding steel pipe is 1200mm long.

[0007] Preferably, the channel steel is 650mm in length.

[0008] Preferably, the surface of the device is coated with anti-rust paint.

[0009] Secondly, the present invention provides a construction method for an adjustable composite slab formwork support device, comprising the following steps: S1. The support device is hoisted to the construction site by a tower crane. After arriving at the construction site, the support device is connected to the uprights of the existing formwork support system on site by right-angle fasteners. S2. Adjust the height and outward extension of the support device by adjusting the position of the right-angle coupler between the scaffold steel pipe and the upright of the formwork support system; S3. After adjustment, use an electric wrench to tighten the bolts of the right-angle fastener to fix the device. S4. Perform the same operation as above on the other devices to complete the installation of all template support devices.

[0010] In summary, the present invention has at least one of the following beneficial technical effects: This device connects to the existing formwork support system on site via fasteners and can be applied to both steel pipe fastener scaffolding support systems and disc fastener scaffolding support systems. Because the device connects to the existing formwork support system on site via fasteners, it can handle a variety of situations, making it flexible and widely applicable. During the on-site formwork support system erection process, the device is placed at the joint between the composite slab and the wall for support. Then, the device is fixed to the adjacent formwork support system uprights with fasteners to adjust its vertical position and outward extension length. After adjustment, the fastener bolts are tightened with an electric wrench to achieve the purpose of supporting the formwork. Compared to the original support system, this device can reduce the number of uprights and corresponding horizontal bars in the formwork support system while supporting the joint between the composite slab and the wall, thus saving some materials and avoiding situations where the modules do not match and the disc-lock scaffold cannot install uprights.

[0015] The following combination Figures 1-3 The present invention will be described in further detail below.

[0016] This invention discloses an adjustable composite slab formwork support device and construction method. The device includes a scaffolding steel pipe 1, which is horizontally arranged and uses a standard φ48.3×3.6 scaffolding steel pipe. One end of the scaffolding steel pipe 1 is fixed to the upright of the adjacent formwork support system by a right-angle coupler 2. The right-angle coupler 2 can slide on the scaffolding steel pipe 1 and the upright of the formwork support system, thereby adjusting the support height of the device and the outward extension length of the scaffolding steel pipe 1.

[0017] The other end of the scaffolding steel pipe 1 is vertically welded and fixed with a channel steel 3. The center line of the circle on the side of the scaffolding steel pipe 1 coincides with the center line of the web of the channel steel 3. An angle steel 4 is set at the top of the channel steel 3. The middle section of the flange of the channel steel 3 and the angle steel 4 are perpendicular. The angle steel 4 is placed horizontally. The center line of the web of the channel steel 3 coincides with the midpoint of the flange of the angle steel 4. The angle steel 4 is welded and fixed to the channel steel 3.

[0018] Angle steel 4 serves as a support plate to fix the formwork; channel steel 3 serves as a support part to support angle steel 4; scaffolding steel pipe 1 is the end force transmission structure, which is fixed to the upright of the adjacent formwork support system by right-angle coupler 2, and is responsible for transmitting the force of the upper formwork, and dispersing the force transmitted from the upper load through the device by the adjacent formwork support system; right-angle coupler 2 plays a role in fixing the entire device, and the extension length and installation height of the device can be adjusted by loosening the coupler bolts.

[0019] In a specific embodiment, a 1200mm long standard scaffolding steel pipe 1 with a diameter of φ48.3×3.6 is taken, without welding or rust. A 12.6 channel steel 3 is cut to a length of 650mm. A type 2 hot-rolled equilateral angle steel 4 is cut to a suitable length. The 12.6 channel steel, the type 2 hot-rolled equilateral angle steel, and the φ48.3×3.6 standard scaffolding steel pipe are welded together as follows: Figure 1 As shown in the figure, after welding, apply anti-rust paint to the surface of the device. After the anti-rust paint dries, connect it to the on-site template support system through right-angle fastener 2.

[0020] The construction method of the adjustable composite slab formwork support device according to an embodiment of the present invention includes the following steps: S1. The support device is hoisted to the construction site by a tower crane. After arriving at the construction site, the support device is connected to the uprights of the existing formwork support system on site through right-angle coupler 2. S2. Adjust the height and outward extension length of the support device by adjusting the position of the right-angle coupler 2 between the scaffolding steel pipe 1 and the upright of the formwork support system; S3. After adjustment, use an electric wrench to tighten the bolts of the right-angle fastener 2 to fix the device. S4. Perform the same operation as above on the other devices to complete the installation of all template support devices.

[0021] The template support device of this invention connects to the existing template support system via fasteners, making installation convenient and applicable to a wide range of applications. During installation, the device's vertical position and extension length can be adjusted using fasteners, facilitating operation. Furthermore, the device is simple to install and easy to learn, operating in the same way as fastener-type scaffolding, allowing scaffolders to operate it directly without additional training. Since the device connects to the template support system using fasteners, it can be used with ring-lock scaffolding, disc-lock scaffolding, and fastener-type scaffolding, offering wide applicability and flexible use.

[0022] This device can be installed simultaneously with the formwork support system, and can be removed at the same time as the formwork support system after the concrete pouring is completed, without spending extra time and saving construction time.

[0023] In actual operation, this invention reduces the time spent in the erection of the formwork support system and improves the erection efficiency of the formwork support system. On the other hand, the time spent on dismantling and sorting materials during the dismantling of the formwork support system is less than before, proving that the use of this device improves construction efficiency.

[0024] The adjustable formwork support device provided in this embodiment has the characteristics of wide applicability, simple principle, low operation difficulty, easy to learn, long service life and reusability. It reduces the material used at the joint between the composite slab and the wall during the erection of the composite slab formwork support system, simplifies the erection process, improves work efficiency and speeds up construction.

[0025] Compared with existing technologies: 1. This device connects to the existing formwork support system on site via fasteners and can be applied to both steel pipe fastener scaffolding support systems and disc fastener scaffolding support systems. Because this device connects to the existing formwork support system on site via fasteners, it can handle various situations, is flexible in application, and has a wide range of applications. 2. During the on-site formwork support system erection, the device is placed at the joint between the composite slab and the wall for support. Then, the device is fixed to the adjacent formwork support system uprights with fasteners and the vertical position and extension length of the device are adjusted. After the adjustment is completed, the fastener bolts are tightened with an electric wrench to achieve the purpose of supporting the formwork. 3. Compared with the original support system, this device can reduce one row of uprights and corresponding horizontal bars of the formwork support system while supporting the joint between the composite slab and the wall, thus saving some materials and avoiding the situation where the module does not match and the uprights of the disc-lock scaffold cannot be installed.

[0026] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
