Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a mounting and fixing device suitable for lightweight integrated construction platforms. Background Technology

[0002] Lightweight integrated construction platform, also known as "building machine", is mainly composed of support system, steel platform system, hanging frame system, formwork system, and auxiliary facilities system. It is an integrated multi-layer operation platform that can integrate construction tools and material storage yards. Compared with traditional frames, it is lighter, more intelligent and standardized.

[0003] The main load-bearing frame of the steel platform and the entire load of the working bracket layer are ensured by setting up supports around the building or in the central shaft at intervals of 13-18 meters, guaranteeing balanced stress on each support column during the construction platform's static or lifting process. Each support column of the lightweight integrated construction platform is attached to the wall by high-strength bolts on three brackets. When designing the bracket positions, in most cases, they can be placed on straight shear walls. In this case, the bracket installation and removal are simple, and the stress distribution is reasonable.

[0004] With the gradual development of residential building design, construction units are integrating the primary structure with some secondary structures, making the walls between bay windows on the south side of buildings a common practice. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a mounting bracket fixing device suitable for lightweight integrated construction platforms, so that the load of the supporting column and matching bracket at the bay window wall of the building using the lightweight integrated construction platform can be effectively transferred, thus ensuring the safe operation of the platform.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: Construct a mounting bracket fixing device suitable for a lightweight integrated construction platform, used to fix the bracket to the wall. The bracket is set on a supporting column, and multiple brackets and supporting columns bear the entire load of the lightweight integrated construction platform. The mounting bracket fixing device includes a rectangular connecting seat and a trapezoidal connecting seat. The rectangular connecting seat is located between the bracket and the trapezoidal connecting seat. The rectangular connecting seat is fixedly connected to the bracket. The rectangular connecting seat is fixedly connected to the trapezoidal connecting seat. The trapezoidal connecting seat is fixed to the wall.

[0007] According to the above scheme, the rectangular connecting seat includes two first end plates and a stiffening plate. The two first end plates are arranged in parallel, and the stiffening plate is connected between the two first end plates.

[0008] According to the above scheme, the first end plate and the stiffening plate are fixed by welding.

[0009] According to the above scheme, the trapezoidal connecting seat includes a first end plate, a second end plate, and a stiffening plate. The first end plate and the second end plate are arranged in parallel, and the stiffening plate is connected between the first end plate and the second end plate.

[0010] According to the above scheme, the stiffening plate is fixed between the first end plate and the second end plate by welding.

[0011] According to the above scheme, the rectangular connecting seat and the trapezoidal connecting seat are provided with corresponding bolt connection holes.

[0012] According to the above scheme, the top of the rectangular connecting seat is provided with a lifting ring.

[0013] According to the above scheme, the trapezoidal connecting seat is connected to the wall by through-wall bolts.

[0014] According to the above scheme, the trapezoidal connecting seat is connected to the pre-embedded climbing cone in the wall by bolts.

[0015] The mounting and fixing device for lightweight integrated construction platforms according to this utility model has the following beneficial effects:

[0016] 1. This utility model uses a hanging fixing device composed of rectangular steel components and trapezoidal steel components. The rectangular steel components are on the outer side and the trapezoidal steel components are on the inner side. This structural form is conducive to the transfer of loads, and allows the standardized components of the supporting columns and hanging system of the lightweight integrated construction platform to be implemented in the structure of the integrated construction of building bay windows, thereby improving the adaptability of the intelligent lightweight integrated construction platform equipment.

[0017] 2. In the components of the mounting bracket fixing device of this utility model, since the steel components have a uniform width, the trapezoidal steel components are first installed according to the design position, and after the high-strength bolts are fixed, the rectangular steel components and the bracket are then installed using this as a reference. The connection between the outer rectangular steel component and the bracket, and the connection between the inner trapezoidal steel component and the wall, are all made using the same type of M42 steel with a length of 350mm. The width of the steel components is 180mm, which is less than the 300mm width between the supporting column and the wall, and the weight is relatively light, allowing for manual installation and fixing, thus improving work efficiency.

[0025] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 6 As shown, this utility model is applicable to the mounting bracket fixing device and installation method of a lightweight integrated construction platform, including a mounting bracket fixing device 1, a rectangular steel component 2, a trapezoidal steel component 3, a high-strength bolt 4, a pre-embedded climbing cone 5, a mounting bracket 6, a supporting column 7, a first end plate 8, a high-strength bolt hole 9, a second end plate 10, a stiffening plate 11, a bolt reserved hole 12, a steel structure reserved hole 13, and a lifting ring 14.

[0027] like Figures 1-3 As shown, when designing and using the lightweight integrated construction platform (building machine), based on the distribution of the supporting columns 7 on the building structure plane, it needs to be installed in the wall position between the bay windows; otherwise, the overall load of the platform cannot be well borne. The standard component's bracket 6 needs to transfer the load to the structural wall through the bracket fixing device 1. The bracket fixing device 1 consists of a rectangular steel component 2 and a trapezoidal steel component 3. The outer rectangular steel component 2 is connected to the bracket 6 and the trapezoidal steel component 3 by M42 high-strength bolts 4, and the inner trapezoidal steel component 3 is connected by... The M42 high-strength bolts 4 are connected to the wall. For bolts that cannot pass through the wall, pre-embedded climbing cones 5 and external M42 high-strength bolts 4 are used to connect to the trapezoidal steel components. All high-strength bolts 4 are inserted from the outside to the inside, fixed with double nuts, and three threads are exposed. Since the load transmitted from the platform to the supporting column 7 and the hanging seat 6 is transmitted to the trapezoidal steel component 3 through the rectangular steel component 2, and then borne by the wall, after tightening all the high-strength bolts 4, they can achieve the same load-bearing function as other through-wall bolts located in the straight shear wall.

[0028] like Figure 4As shown, after the initial installation of the support column 7, its planar position remains unchanged, only its height increases with the continuous improvement of the structure. Each support column 7 of the support system using this bracket fixing device 1 has three brackets 6. Each time the uppermost bracket 6 is installed, the support column 7 is lifted to the predetermined height under the drive of the hydraulic system. The operator first moves the trapezoidal steel component 3 (thickness 180mm) from the space between the support column 7 and the structural wall (300mm at the narrowest point) into the designed position. The high-strength bolts 4 are distributed in upper and lower rows. All high-strength bolt holes are designed as elongated holes, which facilitates fine-tuning left and right when needed during on-site installation. First, install the high-strength bolts 4 on both sides of the upper row, then perform pre-tightening for initial positioning. After adjustment, install and tighten the high-strength bolts 4 in the middle of the upper row onto the embedded climbing cone 5. Then install the high-strength bolts 4 on both sides of the lower row of the trapezoidal steel component 3, and then tighten all the high-strength bolts 4 of the trapezoidal steel component 3. The middle of the lower row of the steel component and the bracket 4 are all bolt pre-drilled holes 12, which facilitates the installation of replacement bolts in special cases such as when the bolt holes are blocked. After the trapezoidal steel component 3 is installed and fixed, the rectangular steel component (180mm thick) is moved into the designed position through the space between the supporting column 7 and the structural wall (300mm at the narrowest point). Since the first end plate 8 of the rectangular steel component 2 and the first end plate 8 of the trapezoidal steel component 3 are the same component, the rectangular steel component 2 is installed close to the trapezoidal steel component 3. During installation, the top lifting ring 14 is used for auxiliary positioning and fixing to maintain the positioning state of the rectangular steel component 2. The hanging bracket 6 is then installed. The standard component base plate is the same size as the first end plate 8 of the rectangular steel component 2. The bracket is installed tightly with reference to the positioning of the rectangular steel component 2. Then, high-strength bolts 4 on the left and right sides of the first row are inserted from the outside to the inside and pre-tightened. The high-strength bolts 4 in the middle position of the upper row are installed. Finally, the high-strength bolts 4 on both sides of the lower row are installed. The high-strength bolts 4 pass through the bracket 6 and the rectangular steel component 2 and are fixed on the trapezoidal steel component 3. After the double nuts are tightened, three threads are exposed. The installation is completed. The bracket 6 can enter the working state of providing support for the column 7 in both static and lifting states.

[0029] like Figures 5-6 As shown, the rectangular steel component 2 and the trapezoidal steel component 3 are pre-fabricated to reduce weight while ensuring that the stress meets the requirements during operation. The pre-fabricated holes 13 are aligned front and back on the same steel component and have the same size. The rectangular steel component 2 weighs about 50 kg and the trapezoidal steel component 3 weighs about 60 kg. This facilitates the handling of the components by the operators, shortens the installation time of the hanging bracket fixing device 1, and improves the overall work efficiency. The complete lifting and installation process is as follows: the drive system inside the support column 7 drives the construction platform to the predetermined height. The lowest hanging bracket 6 and its fixing device 1 on the support column 7 are removed. The components are then moved to the predetermined installation position on the uppermost floor according to the method described above for installation, and the next lifting of the lightweight integrated construction platform is carried out.

[0030] The complete installation and operation process of this utility model is as follows:

[0031] After the lightweight integrated construction platform and its supporting columns are raised to the predetermined height, two of the three brackets at the supporting columns will continue to bear the load. The bottom bracket needs to be promptly and vertically moved to the designed position on the new construction floor. Following the sequence from the outside in: bracket, rectangular steel component, and trapezoidal steel component, the bolts are loosened and removed step by step. Using crane machinery, the components are transported to the predetermined position at the top of the supporting columns. First, the trapezoidal steel component is fixed tightly against the structural wall. High-strength bolts are passed through pre-embedded bolt holes and pre-embedded climbing cones in the structural wall and tightened. Next, the rectangular steel component is positioned. After positioning, the rectangular steel component should be flush with the width of the trapezoidal steel component, and the bolt holes should be aligned. Maintaining the position of the rectangular steel component, the bracket is hoisted to the outside of the rectangular steel component for positioning, with its height and width flush with the rectangular steel component and the bolt holes aligned. High-strength bolts are passed through the bracket and rectangular steel component from the outside in, and double nuts are used to fix it to the trapezoidal steel component, completing the installation of the load transfer system. Because the mounting bracket adopts a split structure, the support column has reached the designed position each time it is installed, and the space between it and the wall is 300mm. The thickness of the rectangular and trapezoidal steel components is 180mm, and the space meets the installation requirements.

[0032] Preferably, the mounting bracket fixing device is mainly composed of rectangular steel components and trapezoidal steel components. The outer rectangular steel components are connected to the mounting bracket by high-strength bolts, and the inner trapezoidal steel components are connected to the wall by high-strength bolts and pre-embedded climbing cones.

[0033] Preferably, the mounting bracket is installed on the wall between bay windows in a residential building, and using this device has the same force-bearing effect as installing the bracket on a straight shear wall.

[0034] Preferably, the rectangular steel component is welded from two first end plates and a stiffening plate, with planar dimensions consistent with the bracket and a thickness of 180mm.

[0035] Preferably, the trapezoidal steel member is welded from a first end plate, a second end plate, and a stiffening plate, with a thickness of 180mm.

[0036] Preferably, the high-strength bolts are M42×350mm, which connect the bracket and the bracket fixing device, and connect the bracket fixing device to the wall.

[0037] Preferably, the pre-embedded climbing cone is a finished product, and the exposed end is connected with a high-strength bolt.

[0038] Preferably, the brackets and support columns are standard design components that are compatible with the lightweight integrated construction platform. Each support column system has three brackets, which are attached to the three floors respectively by high-strength bolts.

[0039] Preferably, the first end plate has dimensions of 550×500×20mm and is made of Q355B, and the second end plate has dimensions of 550×700×20mm and is made of Q355B.

[0040] Preferably, the mounting bracket fixing device is designed as a separate rectangular steel component and a trapezoidal steel component, which ensures that there is enough space in the wall between the bay windows for mechanical hoisting and manual installation.

However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
