Description

Technical Field

[0001] This invention relates to the technical field of shipbuilding workshops, and more particularly to large-tonnage ships, modular and digital shipbuilding technology, specifically a support frame structure for a shipyard load-bearing floor and its construction method. Background Technology

[0002] In order to improve the load-bearing capacity of the indoor floor of some shipbuilding projects and to facilitate the segmented fixing of the slipway, an additional support structure is set in the floor before the floor is poured. This additional support structure is usually called a "T-shaped embedded part".

[0003] Typically, T-shaped embedded parts are prefabricated in factories, mainly by welding flat steel bars that are perpendicular to each other. The length of these prefabricated T-shaped embedded parts is also fixed, for example, a T-shaped embedded part is 10 meters long. Therefore, when a grid-like support structure is required, the T-shaped embedded parts need to be repeatedly cut to achieve the above requirements.

[0004] The following technical problems exist with the aforementioned T-shaped embedded parts:

[0005] 1. When the length of the T-shaped embedded parts is fixed and a grid-like support structure is required, some of the T-shaped embedded parts need to be cut on-site, which increases the number of procedures.

[0006] 2. Current T-shaped embedded parts are usually welded from mutually perpendicular plates. In this process, it is difficult to guarantee the perpendicularity between the plates. At the same time, in order to achieve sufficient support, the thicker the plate, the better the support effect. However, the increase in plate thickness will lead to an increase in the difficulty of welding operations. If the welding process is not up to standard, problems such as weld cracking and uneven welds will inevitably occur. Summary of the Invention

[0007] The purpose of this invention is to overcome the above-mentioned defects and propose a support frame structure for shipyard load-bearing floors with small welding deformation, fast construction speed and guaranteed quality, as well as its construction method.

[0008] To achieve the above objectives, the present invention is implemented as follows:

[0009] A support structure for a shipyard load-bearing floor includes a support rod with a "T"-shaped cross-section, and connecting rods or connecting plates disposed on both sides of the support rod.

[0010] The support frame structure of the shipyard load-bearing floor has through holes fixedly spaced on the vertical rods of the support rods. These through holes are used to pass the reinforcing bars through the through holes when the reinforcing mesh of the floor is tied, thereby connecting the support rods and the reinforcing bars into a whole.

[0011] The support frame structure of the shipyard load-bearing floor has a connecting rod whose side projection is in the shape of an "eight". A hook is provided at its outwardly flared end. The hook is used to hook the connecting rod to the steel bar when binding the steel mesh of the floor, thereby connecting the support rod and the steel bar into a whole.

[0012] A method for constructing a shipyard load-bearing floor with the aforementioned support structure; including...

[0013] Step 1: Make a "T"-shaped support rod using I-beams, the length of which shall not exceed 100mm;

[0014] Step 2: Lay the steel mesh for the floor slab;

[0015] Step 3: Connect the steel mesh to the "T"-shaped support rod using connecting rods or connecting plates.

[0016] in,

[0017] When the design load-bearing target of the area where the "T"-shaped support rod is located is 5t, the "T"-shaped support rod is connected to the steel mesh using an "eight"-shaped connecting rod. One end of the connecting rod is welded to the "T"-shaped support rod, and the other end of the connecting rod hooks onto the steel mesh, thus connecting the "T"-shaped support rod and the steel mesh into a whole.

[0018] or,

[0019] When the design load-bearing target of the area where the "T"-shaped support rod is located is 20t, a connecting plate with an "L"-shaped side projection is used to provide ground support for the "T"-shaped support rod. At the same time, through holes are opened evenly at intervals on the side of the "T"-shaped support rod. When the steel mesh is tied, it passes through the through holes on the side of the "T"-shaped support rod, so that the "T"-shaped support rod and the steel mesh are connected into a whole.

[0020] Step 4: Concrete pouring is carried out. During the pouring process, an immersion vibrator is used for vibration. The surface layer is first polished with a grinder to remove slurry, and then finely leveled with a 5m scraper and a trowel. The position near the "T"-shaped support rod is manually coated with slurry and troweled.

[0021] Step 5: After the concrete reaches a certain strength, cover the surface of the floor with geotextile; after final setting, water for curing.

[0022] The above-described method for constructing the shipyard's load-bearing floor,

[0023] In step 2, before laying the steel mesh, the ground needs to be treated, including...

[0024] Step 2.1: Compact the subgrade soil;

[0025] Step 2.2: Lay a 600mm thick graded crushed stone cushion layer with a compaction coefficient of 0.95, followed by a 100mm thick C20 concrete cushion layer.

[0026] Step 2.3: After the subfloor layer is completed and reaches the design strength, the bottom layer of steel reinforcement is laid.

[0027] The method for constructing the shipyard's load-bearing floor.

[0028] In step 3, after the T-shaped support rods are laid, the elevation of the T-shaped support rods is controlled by a level.

[0029] In step 3, when laying a floor with a load-bearing target of 5t, the steel mesh is a single-layer structure, and the elevation is controlled by steel bar supports during binding. When constructing a floor with a load-bearing target of 20t, the steel mesh is a double-layer structure. The lower layer of steel mesh is laid first, and the steel bars of this layer are connected to the "T"-shaped support rods. Then the upper layer of steel mesh is constructed, and the elevation of the upper layer of steel mesh is controlled by steel bar supports.

[0030] In the construction method of the shipyard load-bearing floor, step 1, the use of I-beams to make "T"-shaped support rods specifically refers to the process in a prefabrication plant of horizontally cutting finished I-beams or rails from their webs to form support rods with a "T" shape in their side projection. At the same time, the I-beams are cut in 100mm increments, and then the 100mm long "T"-shaped support rods are welded together to form a grid-like support structure according to the design requirements.

[0031] The "T"-shaped support rod and its attached connecting rod structure proposed in this invention are easy to mass-produce and have guaranteed quality. At the same time, using I-beams or railway rails as support rods provides stronger load-bearing capacity and avoids the quality risks associated with thick plate welding. Furthermore, during the manufacturing process of the flooring proposed in this invention, the support components are connected to the flooring reinforcement bars. Thus, after the concrete is poured and solidified, it can achieve higher "integration" and load-bearing capacity, avoiding floor collapse and cracking problems caused by long-term load-bearing.

The through holes 4 are used to pass the steel bars through the through holes 4 when the steel mesh of the floor is tied, thereby connecting the support rod 1 and the steel bars into a whole.

[0037] The support frame structure of the shipyard load-bearing floor has a connecting rod 2 with a side projection of an "eight" shape. A hook 5 is provided at its outwardly flared end. The hook 5 is used to hook the connecting rod 2 to the steel bar when binding the steel mesh of the floor, thereby connecting the support rod 1 and the steel bar into a whole.

[0042] in,

[0043] When the design load-bearing target of the area where the "T"-shaped support rod is located is 5t, the "eight"-shaped connecting rod is used to connect the "T"-shaped support rod to the steel mesh. One end of the connecting rod is welded to the "T"-shaped support rod, and the other end of the connecting rod hooks onto the steel mesh, so that the "T"-shaped support rod and the steel mesh are connected as a whole.
