Description

Technical Field

[0001] The invention relates to the technical field of building formwork, and in particular to an aluminum alloy formwork construction system. Background Art

[0002] In the design of building structures, there are often parts that extend outwards and hang in the air. Through these parts, integral casting is also required, and building formwork needs to be built in advance. In the traditional treatment method, scaffolding is used to build support frames on the ground or the nearest support surface for vertical support, which belongs to high-support formwork construction. This implementation method undoubtedly consumes operation time and increases the time of construction equipment.

[0003] Currently, most construction projects use wooden formwork to support and reinforce buildings with irregular cantilever structures, shapes, lines that are difficult to support, or special parts that are not firmly reinforced. Conventional aluminum formwork is only used for buildings with standard structures.

[0004] When all wooden formwork is used for construction, the material utilization rate is low, the construction cycle is slow, and a lot of construction waste will be generated, polluting the environment. It is not conducive to green construction. When all aluminum formwork is used for construction, for complex shapes, facade lines and cantilever structures, the cost of using customized aluminum formwork alone is high, and the turnover rate and utilization rate are low.

[0005] In this context, in order to solve the above problems, this construction method proposes targeted optimization measures, using a combination of aluminum and wood to optimize special nodes to solve the problem that aluminum formwork cannot be used for complex-shaped buildings.

[0006] In addition, the use of the distance between the wooden mold and the aluminum mold requires the pre-production and transportation of the aluminum mold, and the scheduling of the aluminum mold also needs to be further optimized. Summary of the invention

[0007] In order to solve the above problems, the present invention discloses an aluminum alloy formwork construction system, comprising the following contents: Step 1: Simulate the construction of building templates on the software platform; Step 2: The templates within the same area are divided into batches, and a traceability code is generated for the same batch of building templates. The webpage pointed by the traceability code displays a three-dimensional distribution diagram of the batch of building templates; Step 3: Pack and transport the building templates included in the traceability code to the construction site. The above-mentioned scheduling of the building templates is clarified, which greatly promotes the progress of construction; Step 4: Apply release agent on the surface of the building formwork and build it, which includes the following: 1>, the arc transition between standard aluminum molds is to bend wooden boards on site to make wooden molds. If the two casting surfaces are not 90°, non-standard aluminum molds are used. The building formwork is mainly standard aluminum molds, supplemented by non-standard aluminum molds and wooden molds. The use of non-standard aluminum molds and wooden molds does not require customization of specific building structures, reducing the application cost of the formwork; 2> For cantilever casting surfaces with vertical support height exceeding one floor, inclined support is used for fixation, and the minimum spacing of the inclined support is calculated. Traditionally, vertical support is directly set below the cantilever casting surface. Due to the structure of the extended surface, the height of the support is relatively large. The inclined support not only saves materials while ensuring safety and quality, reduces labor costs, improves construction efficiency, but also reduces construction workload; Step 5: After the reinforcement is laid and the building formwork is set up, pouring is carried out; Step 6: After curing, remove the building formwork and mark it according to the new traceability code or store it together in the same batch to facilitate subsequent reuse or transfer.

[0008] The wooden formwork includes a bent plate, and the upper and lower parts of the plate are horizontally fixedly connected with arc-shaped plates, and both sides of the plate are fixedly connected with wooden strips. The arc-shaped plate is provided to maintain the arc shape of the plate, and the wooden strip is used for fixed connection with the standard aluminum formwork. At the same time, if the upper and lower sides of the wooden formwork are casting surfaces, wooden boards need to be added to the wooden formwork.

[0009] The non-standard aluminum mold is used for wall corners and includes a plate, one side of the plate is removed from the frame, and a connecting rod is arranged between the two plates. By controlling the length of the connecting rod, the angle between the two plates is controlled to meet the construction needs.

[0010] The upper and lower ends of the oblique support are respectively provided with a base and an upper fixing piece, the lower end of the oblique support is matched with the inclined surface preset on the upper part of the base, and the upper fixing piece is fixed to the standard aluminum mold. The oblique support is fixed by using the base and the upper fixing piece.

[0011] The base is provided with fixing bolts, the lower end of the oblique support is fixedly connected with a bottom plate, and the bottom plate is penetrated by fixing bolts, and the base is fixedly connected to the building by fixing bolts. That is, it is fixed to the base by fixing bolts, and then the oblique support is fixedly connected to the base by fixing bolts.

[0012] The lower end of the upper fixing member is provided with a convex column, the upper end of the oblique support is sleeved on the convex column, and the upper end of the upper fixing member is provided with an anti-slip strip, that is, the upper end of the oblique support is sleeved on the convex column.

[0013] The beneficial effects of the present invention are as follows: 1. The joint use of wooden formwork and aluminum formwork, especially in the formwork construction of extended casting structures, is based on the stable performance of aluminum formwork and the use of inclined support. It not only saves materials while ensuring safety and quality, reduces labor costs, and improves construction efficiency, but also reduces construction variables and makes acceptance more intuitive and controllable.

[0014] 2. In the arc structure, the method of on-site production of wooden molds is adopted, and the use of aluminum molds is combined to greatly reduce the production of special-shaped aluminum molds. Most aluminum molds are standard parts, that is, the common use of wooden molds and aluminum molds meets the construction needs, while reducing the generation of construction waste and facilitating the turnover and reuse of aluminum molds.

[0015] 3. By utilizing the software platform, the construction formwork is simulated and packaged and transported in batches with traceability codes, which is conducive to the use of the construction formwork and speeding up the construction progress. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0019] like Figures 1 to 8 As shown, an aluminum alloy formwork construction system includes the following contents: Step 1: Simulate the construction of the building formwork on the software platform. Specifically, after the initial deepening of the first version of the drawing, pre-assemble it through the BIM model to reduce the traditional physical assembly workload and shorten the overall production period. Classify and number the aluminum formwork model according to the type and keep a record.

[0020] Step 2: The templates in the same area are divided into batches, and the same batch of building templates generates a traceability code. The webpage pointed to by the traceability code displays the three-dimensional distribution diagram of the batch of building templates. Specifically, according to the actual situation of the pre-assembly of the model, adjustments and optimizations are made again to ensure the integrity and feasibility of the detailed drawings, form the final version of the detailed drawings, upload the models in groups, and make QR codes for construction personnel to read in time; Step 3: Pack and transport the building templates included in the traceability code to the construction site. Specifically, the building templates required in the steps are classified and produced. The templates produced are mainly standard aluminum templates 1, and special-shaped aluminum templates that cannot be made by plates on the construction site. The processed aluminum alloy templates are classified and marked according to the drawing partitions, and packaged according to the same type of specifications and models. When packing and storing, pads should be placed between the templates to prevent extrusion and deformation. The number of templates transported at one time should not be less than that of one building to avoid confusion caused by improper lifting and transportation connection; Step 4: Apply a release agent on the surface of the building formwork and build it. The standard aluminum formwork 1 includes a plate-like member, a connecting rod used for a 90° wall corner, a connecting member and a supporting member used during the building process. The supporting member includes a vertical support 4, an oblique support 5, and a fence rod, etc. The vertical support 4 and the oblique support 5 are only different in the supporting direction, and their structures are the same. The above components are all commonly used structures for building existing building formworks, which will not be repeated here, and include the following contents: 1>, the arc transition between the standard aluminum mold 1 is to bend the wooden board on site to make the wooden mold 2. The wooden mold 2 is made on site, so there is no need to customize the aluminum mold, which reduces the construction cost. If the two casting surfaces are not 90°, non-standard aluminum mold 3 is used, which also reduces the construction cost. At the same time, non-standard aluminum mold 3 is Figure 4 As shown, it is convenient for construction at any angle; 2>, the vertical support height exceeds the cantilever casting surface of one floor. In the architectural structure design, for example, a balcony is set on one floor, but there is no balcony on the three or four floors below. During the casting process, the distance between the balcony and the support surface directly below will undoubtedly increase the construction difficulty and construction time if vertical support is used. The inclined support 5 is used for fixing. The inclined support 5 solves the problem of balcony casting support and calculates the minimum spacing of the inclined support 5, such as Figure 8As shown, multiple inclined supports 5 are set up in the 3D3S software, and nodes are established for digital identification. Based on the "Steel Structure Design Standard", "Building Structure Load Code", "Steel Structure Welding Code" and "Technical Code for High-Strength Bolt Connections of Steel Structures", the constant load of 2.8KN / m is calculated. 2 , active load 1.5KN / m 2 , the spacing of the oblique supports 5 is obtained to meet the minimum support strength and support angle.

[0021] Step 5: After the reinforcement is laid and the building formwork is set up, pouring is carried out; Step 6: After curing, remove the building formwork and mark it according to the new traceability code or store it together in the same batch to facilitate sorting and transportation and reuse.

[0022] like Figure 3 As shown, the wooden formwork 2 includes a bent plate, the bending posture of the plate is processed on-site according to the construction requirements, and the upper and lower parts of the plate are horizontally fixedly connected with arc-shaped plates, and the arc-shaped plates are rib plates that maintain the arc-shaped structure of the plate. Both sides of the plate are fixedly connected with wooden strips, which are used to fix the wooden formwork 2 and the aluminum formwork by wooden strips, screws, etc.

[0023] like Figure 4 As shown, the non-standard aluminum formwork 3 is used for wall corners and includes a plate. The frame is removed from one side of the plate, that is, the vertical edge that increases the structural strength is removed, and an angle is set. A connecting rod is set between the two plates. By changing the length of the connecting rod, the angle between the two plates also changes, thereby meeting the construction needs of wall corners at different angles.

[0024] The upper and lower ends of the inclined support 5 are respectively provided with a base 7 and an upper fixing piece 9, which realize the support and fixation of the inclined support 5. The lower end of the inclined support 5 is matched on the preset inclined surface on the upper part of the base 7, and the upper fixing piece 9 is fixed to the standard aluminum mold 1.

[0025] The base 7 is provided with fixing bolts 8, the lower end of the inclined support 5 is fixedly connected to the bottom plate 6, and the bottom plate 8 is penetrated by the fixing bolts 8, that is, the lower end of the inclined support 5 is fixedly connected to the base 7 through the fixing bolts 8, and the base 7 is fixedly connected to the building through the fixing bolts 8.

[0026] A boss 10 is provided at the lower end of the upper fixing member 9, and the upper end of the inclined support 5 is sleeved on the boss 10. An anti-slip strip 11 is provided at the upper end of the upper fixing member 9, that is, the boss 10 is sleeved inside the upper end of the inclined support 5, which has the advantage of simple assembly.
