Description

Technical Field

[0001] This invention relates to the field of corbel construction technology, specifically to a reusable device and construction method for corbel formwork construction. Background Technology

[0002] The factory project has a large number of corbel structures of the same specifications. In traditional construction engineering, we use wooden formwork to construct the corbels. However, since the corbels are convex structures with irregular shapes, the reinforcement methods are relatively complicated, the construction efficiency is low, the formwork has a low turnover rate, and improper reinforcement during construction may cause quality problems such as corbel misalignment. Summary of the Invention

[0003] The purpose of this invention is to provide a reusable device for corbel formwork construction, which solves the problem of low reusability of formwork caused by the use of wooden formwork for corbel structure construction in the prior art.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] Reusable devices for corbel column formwork construction include:

[0006] The main steel formwork and the secondary steel formwork are detachably connected;

[0007] Two vertical steel pipes are provided, one of which is fixedly connected to the main steel formwork, and the other of which is fixedly connected to the auxiliary steel formwork.

[0008] Two horizontal steel pipes are respectively set at both ends of the vertical steel pipe, and the horizontal steel pipes and the vertical steel pipes are detachably connected.

[0009] When the main steel formwork and the secondary steel formwork are fixedly assembled, an open pouring cavity is formed between the main steel formwork and the secondary steel formwork.

[0010] As a further aspect of the present invention, the main steel template and the secondary steel template are fixed together by a number of bolts on their interlocking end faces.

[0011] As a further embodiment of the present invention: the main steel template and the secondary steel template are respectively welded and fixed to the transverse steel pipe.

[0012] As a further aspect of the present invention, the horizontal steel pipe and the vertical steel pipe are fixed together by fasteners.

[0013] As a further aspect of the present invention: multiple reinforcing bars are welded and fixed to the bottom ear plates of the main steel template and the secondary steel template respectively.

[0014] As a further aspect of the present invention: lifting rings are welded and fixed to the main steel template and the secondary steel template respectively.

[0015] A reusable construction method for corbel column formwork construction includes the following steps:

[0016] Step 1: Prefabricate and process the combined steel formwork according to the corbel structure, and fix the main steel formwork and the secondary steel formwork together with several bolts to form an open pouring cavity between the main steel formwork and the secondary steel formwork;

[0017] Step 2: Lift the combined steel formwork onto the wooden formwork of the corbel column, and install the bottom ear plates of the main steel formwork and the auxiliary steel formwork onto the wooden formwork;

[0018] Step 3: Weld the vertical steel pipes onto the main steel formwork and the secondary steel formwork respectively. Connect the two ends of the vertical steel pipes to the horizontal steel pipes with fasteners. Connect the two ends of the horizontal steel pipes to the steel pipe frame of the corbel column with fasteners.

[0019] Step 4: Cast the corbel column and the corbel with the outward protrusion structure in one piece. After the casting and curing are completed, disassemble the combined steel formwork for reuse.

[0020] As a further aspect of the present invention: in step two, multiple reinforcing bars are welded and fixed to the bottom ear plates of the main steel template and the secondary steel template, respectively.

[0021] The beneficial effects of this invention are:

[0022] (1) The main steel formwork and the auxiliary steel formwork are prefabricated to form a combined steel formwork. The combined steel formwork has advantages such as high strength, large combination rigidity, high precision of panel production, tight joints, not easy to deform, good overall formwork integrity and strong seismic resistance. It can improve the disadvantages caused by the traditional use of wooden formwork, such as eliminating leakage and avoiding formwork bursting, and improving the formwork construction effect.

[0023] (2) During the installation of the combined steel plate, the bottom ear plate of the combined steel plate is combined with the wooden formwork and reinforced by the horizontal steel pipe and the vertical steel pipe. This makes it easy to install the combined steel plate on the steel pipe frame of the corbel column, so that the reusable device reinforcement method of this application is easy to operate, has high construction efficiency, and improves the efficiency of on-site construction.

[0024] (3) In addition, after the pouring is completed, the main steel formwork and the secondary steel formwork can be detached and connected, which facilitates quick demolding and can be recycled to the next construction project. Recycling can reduce the waste of traditional wood and other resources, and is energy-saving, environmentally friendly and low-carbon.

[0025] (4) By combining steel molds and wooden molds, the difficulty of reinforcing the corbel is simplified, the work efficiency and the quality of corbel forming are improved, and it can be disassembled and reused. Attached Figure Description

[0033] Please see Figure 1-3 As shown, the present invention is a reusable device and construction method for corbel column formwork construction, including a main steel formwork 1, a secondary steel formwork 2, two vertical steel pipes 4 and two horizontal steel pipes 7. The main steel formwork 1 and the secondary steel formwork 2 are detachably connected. One vertical steel pipe 4 is fixedly connected to the main steel formwork 1, and the other vertical steel pipe 4 is fixedly connected to the secondary steel formwork 2. The two horizontal steel pipes 7 are respectively set at both ends of the vertical steel pipes 4, and the horizontal steel pipes 7 are detachably connected to the vertical steel pipes 4. When the main steel formwork 1 and the secondary steel formwork 2 are fixedly assembled, the main steel formwork 1 and the secondary steel formwork 2 form an open pouring cavity 9.

[0034] During the formwork construction of corbel columns, in order to meet the formwork construction needs of a large number of corbels with the same specifications protruding structures, the reusable device of this application adopts a prefabricated main steel formwork 1 and a secondary steel formwork 2 to form a combined steel formwork. The combined steel formwork has advantages such as high strength, high rigidity, high precision in panel fabrication, tight joints, resistance to deformation, good overall formwork integrity, and strong seismic resistance. It can improve the drawbacks caused by the traditional use of wooden formwork, such as eliminating leakage and avoiding formwork bursting, thus improving the formwork construction effect. Moreover, during the installation of the combined steel plates, the assembly... The bottom ear plate of the composite steel plate is combined with the wooden formwork and installed. The horizontal steel pipe 7 and the vertical steel pipe 4 are used to reinforce the composite steel plate, which makes it easy to install the composite steel plate on the steel pipe frame of the corbel column. This makes the reusable device reinforcement method of this application simple to operate, efficient in construction, and improves the efficiency of on-site construction. In addition, after the pouring is completed, the main steel formwork 1 and the secondary steel formwork 2 can be detachably connected, which facilitates quick demolding and allows for reuse in the next construction project. Recycling can reduce the waste of traditional wood and other resources, and is energy-saving, environmentally friendly and low-carbon.

[0035] In this specific embodiment, the main steel template 1 and the secondary steel template 2 are fixed together by a number of bolts 3 on their interlocking end faces. The bolts 3 can prefabricate the main steel template 1 and the secondary steel template 2 to form a combined steel template, which is convenient to connect. When reused, the main steel template 1 and the secondary steel template 2 can be quickly demolded to achieve reuse and recycling for the next construction project, thus saving construction costs and resources.

[0036] In this specific embodiment, the main steel formwork 1 and the secondary steel formwork 2 are welded and fixed to the transverse steel pipe 7 respectively. According to the on-site construction environment conditions, the main steel formwork 1 and the secondary steel formwork 2 can be prefabricated to form a combined steel formwork installation height, and the transverse steel pipe 7 can be cut to meet the requirements of reinforcement and support.

[0037] In this specific embodiment, the horizontal steel pipe 7 and the vertical steel pipe 4 are fixed together by fasteners 6, so that the horizontal steel pipe 7 and the vertical steel pipe 4 can be detachably connected, which facilitates the quick connection of the reinforcing steel pipe of the combined steel formwork to the steel pipe frame of the corbel column on the construction site, resulting in efficient construction.

[0038] In this specific embodiment, multiple reinforcing bars 8 are welded and fixed to the bottom ear plates of the main steel formwork 1 and the auxiliary steel formwork 2 respectively. The multiple reinforcing bars 8 are used to strengthen the installation connection between the bottom ear plates of the combined steel formwork and the wooden formwork, and the multiple reinforcing bars 8 make the thickness of the combined steel formwork reach the thickness of the wooden formwork, so that it can be quickly spliced ​​with the wooden formwork.

[0039] In this specific embodiment, lifting rings 5 ​​are welded and fixed on the main steel template 1 and the secondary steel template 2 respectively, and the lifting rings 5 ​​facilitate the handling of the combined steel template.

[0040] like Figure 1-3 As shown, the present invention also provides a reusable construction method for corbel column formwork construction, comprising the following steps:

[0041] Step 1: Prefabricate and process the combined steel formwork according to the corbel structure. Fix the main steel formwork 1 and the secondary steel formwork 2 together with several bolts 3. The main steel formwork 1 and the secondary steel formwork 2 form an open pouring cavity 9. Prefabrication and processing of combined steel plates helps to shorten the on-site construction cycle. The combined steel formwork has advantages such as high strength, large combined rigidity, high precision of plate manufacturing, tight joints, not easy to deform, good overall formwork integrity and strong seismic resistance. It can improve the drawbacks caused by the traditional use of wooden formwork, such as eliminating leakage and avoiding formwork bursting, and improving the formwork construction effect.

[0042] Step 2: Lift the combined steel formwork onto the wooden formwork of the corbel column. Install the bottom ear plates of the main steel formwork 1 and the auxiliary steel formwork 2 onto the wooden formwork to achieve rapid combination and formwork construction of the combined steel formwork and the wooden formwork of the corbel column.

[0043] In this step, multiple reinforcing bars 8 are welded and fixed to the bottom ear plates of the main steel formwork 1 and the secondary steel formwork 2. The multiple reinforcing bars 8 are used to strengthen the installation connection between the bottom ear plates of the combined steel formwork and the wooden formwork. The multiple reinforcing bars 8 also make the thickness of the combined steel formwork reach the thickness of the wooden formwork, so that it can be quickly spliced ​​with the wooden formwork.

[0044] Step 3: Weld the vertical steel pipes 4 to the main steel formwork 1 and the secondary steel formwork 2 respectively. Connect the two ends of the vertical steel pipes 4 to the horizontal steel pipes 7 through fasteners 6. Connect the two ends of the horizontal steel pipes 7 to the steel pipe frame of the corbel column through fasteners 6. Use the horizontal steel pipes 7 and the vertical steel pipes 4 to form a composite steel plate for reinforcement. This makes it easy to install the composite steel plate on the steel pipe frame of the corbel column, so that the reusable device reinforcement method of this application is easy to operate, has high construction efficiency, and improves the efficiency of on-site construction operations.

[0045] Step 4: The corbel column and the corbel of the outward protruding structure are formed by integral casting. After the casting and curing are completed, the combined steel formwork is disassembled and reused. It is convenient to quickly demold the combined steel formwork and to reuse it in the next construction project. Recycling can reduce the waste of traditional wood and other resources, and is energy-saving, environmentally friendly and low-carbon.

[0046] In the construction of corbel columns, to meet the needs of a large number of corbels with the same specifications protruding structures, the reusable construction method of this application adopts a prefabricated main steel formwork 1 and auxiliary steel formwork 2 to form a combined steel formwork. The combined steel formwork has advantages such as high strength, high rigidity, high precision in panel fabrication, tight joints, resistance to deformation, good overall formwork integrity, and strong seismic resistance. It can improve the drawbacks of traditional wooden formwork, such as preventing leakage and avoiding formwork bursts, thus improving the formwork construction effect. Furthermore, during the installation of the combined steel plates… In this process, the bottom ear plate of the combined steel plate is installed together with the wooden formwork. The horizontal steel pipe 7 and the vertical steel pipe 4 are used to reinforce the combined steel plate, which makes it easy to install the combined steel plate on the steel pipe frame of the corbel column. This makes the combined steel formwork reinforcement method simple to operate, efficient in construction, and improves the efficiency of on-site construction. In addition, after the pouring is completed, the main steel formwork 1 and the secondary steel formwork 2 can be detachably connected, which facilitates quick demolding and allows for reuse in the next construction project. Recycling can reduce the waste of traditional wood and other resources, and is energy-saving, environmentally friendly and low-carbon.
