Description

Technical Field

[0001] The present invention relates to the technical field of building decoration engineering construction, and in particular to a supporting device and a construction method thereof for supporting a floor steel mesh and subsequent operations. Background Art

[0002] In the field of modern construction, the construction quality of floor slabs is of vital importance, which is directly related to the safety, stability and durability of the entire building structure. Reasonable support of floor slab steel mesh is one of the key links to ensure the quality of floor slabs. There are many problems with the traditional floor slab steel support method. The simple supports used in the early days, such as the "J-shaped" stirrups, are prone to tilting and collapse during the construction process due to factors such as the movement of people, vibration during concrete pouring, and irregular binding, which will seriously affect the quality of the concrete floor slab.

[0003] There are also some existing steel bar support devices, which have certain supporting functions but are cumbersome to operate. And when supporting and adjusting the ends of the steel bars, it is very likely to cause a large height difference between the ends and the middle of the steel bars, which will affect the quality of the floor slab. On the other hand, with the development of building structure design, double-layer bidirectional steel mesh is more and more widely used in concrete floor slabs. However, in order to ensure that there is enough space between the upper and lower layers of steel mesh for concrete filling, a more stable and reliable support device is needed. Existing support devices are often difficult to meet the requirements in the construction of floor slabs with different complex structures and different load requirements.

[0004] At the same time, the demand for support structures varies at different stages of construction. In addition to the need for high-stability support during the steel mesh support stage, in some subsequent operations, such as decoration and renovation projects after the removal of the floor formwork, it may be necessary to use certain components in the floor structure to provide safety belt hanging points for high-altitude operations. The current support structure is difficult to meet the functional requirements of these different stages at the same time.

[0005] How to solve the above technical problems is the subject faced by the present invention. Summary of the invention

[0006] In order to solve the shortcomings of the prior art, the present invention provides a multifunctional stable support device and construction method for floor steel mesh support and subsequent operations in building construction, which is rationally designed, safe and reliable, and aims to ensure the stability of the two layers of steel mesh during the construction process through a stable support frame, and at the same time provide safety belt hanging points for high-altitude workers through a through sleeve and a detachable hanging ring, thereby improving construction safety.

[0026] A: Prefabrication and pre-connection stage;

[0027] Prefabricate the stabilizing support frame, stabilizing rod, through-sleeve and reusable safety belt hanging ring in advance according to the design requirements;

[0028] Assemble stable support frames of different structures according to their design methods;

[0029] At the same time, the stabilizer bar and the through sleeve are pre-connected;

[0030] B: Floor slab formwork laying and hole reservation stage;

[0031] During the laying of the floor slab formwork, the holes should be accurately reserved in advance according to the diameter of the through sleeve at the bottom where the safety belt hanging point is required;

[0032] C: Steel mesh construction and support frame installation stage

[0033] Tie up the steel mesh at the bottom of the floor slab and install the pre-connected stabilizing support frame, stabilizing rod and through-sleeve in place. Use a plugging piece to seal the bottom of the through-sleeve to prevent concrete clogging;

[0034] D: Concrete pouring stage;

[0035] During the pouring of floor slab concrete, the support structure composed of a stable support frame and a stable rod stably supports the two layers of steel mesh to prevent the steel mesh from being displaced due to the impact force and lateral pressure generated by the flow of concrete.

[0036] E: The stage of dismantling the formwork frame and installing the hanging rings;

[0037] After the floor slab concrete reaches a certain strength, the formwork frame is removed;

[0041] G: The stage of recycling and turnover of hanging rings;

[0042] After the work at height is completed, the hanging eye will be removed from the through sleeve, cleaned and inspected before being put back into use for the next construction.

[0043] The steel mesh construction and support frame installation phase includes the following steps:

[0044] C1: The bottom steel mesh construction and support frame installation stage;

[0045] Start tying the steel mesh at the bottom layer of the floor slab;

[0046] Install the pre-connected stabilizing support frame, stabilizing rod and through-sleeve to the appropriate position. During the installation process, ensure that the positional relationship between the stabilizing support frame and the steel mesh meets the design requirements, the through-sleeve on the stabilizing rod accurately penetrates the reserved hole at the bottom of the floor slab formwork, and the bottom of the straight threaded sleeve is firmly sealed with a plugging piece to prevent the concrete from clogging the inside of the sleeve during the subsequent concrete pouring;

[0047] C2: Top layer steel mesh binding stage;

[0048] After the bottom layer of steel mesh is tied and the support frame is installed, the top layer of the floor slab steel mesh is tied to ensure that the spacing and parallelism of the two layers of steel mesh meet the design standards;

[0049] The multifunctional stable support device of the present invention ensures the precise position of the upper and lower layers of steel mesh before and after pouring concrete by designing a precisely designed stable support frame, a stable rod, and a through sleeve. In particular, the stable support frame with an M-shaped structure design, which is composed of a top support rod, a first rod, a second rod, and a stable rod, forms a stable frame, effectively preventing the displacement or deformation of the steel mesh. This design not only improves the overall quality of the floor structure, but also reduces the risk of rework caused by the position deviation of the steel mesh.

[0050] The stable support frame in the present invention is made of high-strength materials, and the components are combined together by threaded connection or integral molding, which greatly enhances the rigidity and bearing capacity of the system. For example, the top support rod, the first rod, the second rod and the stabilizing rod can be integrally molded or formed by bending, which not only simplifies the assembly process, but also ensures the firmness of each connection point, thereby providing reliable support guarantee for large or heavy floor construction.

[0051] The present invention makes installation at the construction site simple and quick by prefabricating and connecting all components in advance. In addition, the design of the through sleeve allows it to be closed with a plugging piece before concrete pouring, avoiding the blockage problem that may occur in traditional methods and simplifying subsequent cleaning work. More importantly, after the formwork frame is dismantled and other high-altitude operations are completed, the reusable safety belt hanging ring can be directly screwed into the through sleeve, providing safety support for the decoration project, further shortening the construction period and improving construction efficiency.

[0052] The through sleeve in the present invention is a permanent embedded part, which can provide a reliable safety belt hanging point for construction workers during the subsequent decoration project. This feature significantly improves the safety of high-altitude operations and reduces the possibility of accidents. At the same time, since the hanging ring is detachable and reusable, it can also be flexibly adjusted according to needs to meet the construction requirements of different stages, reflecting the versatility and flexibility of the device.

[0053] The present invention particularly emphasizes the effective use of resources and environmental protection. On the one hand, the stable support frame and its auxiliary components are made of recyclable materials, which conforms to the concept of green building; on the other hand, the reusable safety belt hanging ring realizes the recycling of resources and reduces the generation of waste. In addition, the optimized design and efficient construction process also indirectly reduce energy consumption and environmental impact.

[0054] The present invention takes into account the specific needs of different construction sites and provides three different stable support frame structure design solutions, including an M-shaped structure, a threaded support base, and a vertical sleeve with a U-shaped lifting support rod. These designs can better adapt to floor slabs of various shapes and sizes, and can find suitable solutions for both small residential projects and large commercial buildings. At the same time, the flexible component layout and adjustment mechanism also provide more options for complex and changing construction conditions. BRIEF DESCRIPTION OF THE DRAWINGS
