[0037] To better understand the purpose, technical solution, and function of this invention, the invention will be described in further detail below with reference to the accompanying drawings. Here, illustrative embodiments and their descriptions are used to explain the invention, but are not intended to limit the invention.
[0038] In the description of this invention, it should be understood that the terms "comprising / including," "consisting of," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a product, apparatus, process, or method that comprises a list of elements includes not only those elements but may also include, where necessary, other elements not expressly listed, or elements inherent to such a product, apparatus, process, or method. Without further limitation, an element defined by the phrase "comprising / including…" or "consisting of…" does not exclude the presence of additional identical elements in the product, apparatus, process, or method that includes said element.
[0039] In this invention, unless otherwise explicitly specified and limited, the term "fixed connection" should be interpreted broadly, for example, it can refer to a sleeve connection, an lap joint, a weld, a bolted connection, or a combination of the above connections; the terms "installation," "connection," and "linking" should also be interpreted broadly, for example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components; the term "continuous reinforcing bar" refers to a reinforcing bar that is continuous without breakage, or a reinforcing bar that is broken but with a fixed connection between the broken reinforcing bars. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0040] The implementation of the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.
[0041] like Figure 1 , Figure 2 As shown, the precast reinforced concrete chamber gravity block includes a filler 1 and a precast reinforced concrete chamber 2. The precast reinforced concrete chamber 2 is enclosed by precast reinforced concrete components 4, and the filler 1 is filled inside the reinforced concrete chamber 2.
[0042] Because this invention uses a precast reinforced concrete chamber to hold the infill material, and the precast reinforced concrete chamber is composed of precast reinforced concrete components, it effectively reduces the amount of concrete used in the gravity block compared to ordinary concrete gravity blocks, thereby reducing the amount of cement and small-diameter sand and gravel used, effectively saving energy and protecting the environment. The precast reinforced concrete chamber is located outside the infill material, improving the impact resistance and load-bearing capacity of the gravity block, and helping to prevent the infill material from overflowing or being damaged during use, thus improving its durability. During manufacturing, the precast reinforced concrete chamber can serve as the outer formwork for the infill material. During use, the precast reinforced concrete chamber can serve as the outer structure of the infill material, bearing its own weight.
[0043] like Figure 1 , Figure 2 and Figure 3 As shown, in this invention, the precast polymer gravity block of the semi-enclosed chamber is composed of a precast reinforced concrete bottom component 4.1 and a precast reinforced concrete side component 4.2, which are fixedly connected as a whole; the precast polymer gravity block is composed of a precast reinforced concrete bottom component 4.1, a precast reinforced concrete side component 4.2, and a precast reinforced concrete top component 4.3, with the precast reinforced concrete bottom component 4.1, precast reinforced concrete side component 4.2, and precast reinforced concrete top component 4.3 fixedly connected as a whole; the precast reinforced concrete component 4 is a precast reinforced concrete slab. The filler 1 is a mixture of granular filler 1.1 and block material 1.2.
[0044] In practice, precast reinforced concrete slabs are typically constructed with a single-layer bidirectional steel mesh or a double-layer bidirectional steel mesh. A double-layer bidirectional steel mesh can further enhance the flexural strength and impact resistance of the precast reinforced concrete slab.
[0045] In practice, the concrete in the precast reinforced concrete chamber is high-strength concrete or UHPC, which can further improve the flexural bearing capacity and impact resistance of the precast reinforced concrete slab.
[0046] In this invention, the precast reinforced concrete component can be a precast reinforced concrete beam-slab or a precast reinforced concrete beam.
[0047] In this invention, the precast reinforced concrete top component 4.3 has an opening to facilitate the filling of filler material 1, further reducing the amount of concrete and steel reinforcement used.
[0048] In this invention, the diameter of the reinforcing bars is 0.2mm to 40mm; the spacing of the reinforcing mesh in the precast reinforced concrete slab is not less than 50mm, which facilitates the compaction of the concrete pouring.
[0049] In this invention, the reinforced concrete chamber 3 has multiple subspaces; the subspaces are independent of each other and are separated by reinforced concrete slabs, and the subspaces contain filler material 1.
[0050] like Figure 4 As shown, in this invention, a lifting device 4 is mounted on the gravity block, with one end embedded in the gravity block and the other end protruding from it. The lifting device is made of steel bars, metal parts, etc., and is used for lifting the gravity block. The filler 1 is a mixture of polymer 1.3 and block material 1.2.
[0051] In this invention, granular material 1.1 includes one or more combinations of gravel, sand, soil, slag, loose solids, and loose waste; block material 1.2 includes one or more combinations of stone blocks, reinforced concrete blocks, concrete blocks, mortar blocks, and block polymers; the particle size of block material 1 is not less than 80mm, which can reduce dust, etc. The difference between the block particle size and the average particle size of the block is not greater than 20% of the average particle size. This ratio requirement makes the difference in block particle size small, which is convenient for controlling the contact mode between blocks or reducing their contact area, and facilitates a more uniform distribution of gravity block mass. Polymer 1.3 includes cement paste, mortar, and concrete; concrete includes ordinary concrete, high-flowability concrete, heavy-duty concrete, fiber concrete, organic concrete, grouting material, and ultra-high performance concrete (HEPA). High-flowability concrete includes self-compacting concrete and highly fluid concrete. High-flowability concrete requires a sufficient amount of powder content, and the coarse aggregate can use a particle size of 5-15mm or 5-25mm. High-flowability concrete is more conducive to filling the gaps between the boxes and achieving the overall compactness of the gravity block.
[0052] In practice, placing fibers or reinforcing ribs inside the filler can improve its stability and reduce cracking.
[0053] like Figure 5 As shown, in this invention, there are holes 5 in the reinforced concrete chamber, and the holes 5 are filled with a filling material to adjust the weight and center of gravity distribution of the gravity block.
[0054] In this invention, the reinforced concrete chamber has grooves; these grooves are located at the top and / or bottom of the reinforced concrete chamber. This facilitates transportation or use.
[0055] A method for preparing precast reinforced concrete chamber gravity blocks, comprising the following steps:
[0056] Step 1: Constructing a precast reinforced concrete chamber 2
[0057] a. Prepare the steel bars and concrete for the precast reinforced concrete chamber 2;
[0058] b. Tie the reinforcing bars of the precast reinforced concrete bottom member 4.1;
[0059] c. Erect the formwork for the precast reinforced concrete bottom component 4.1;
[0060] d. Pour the precast reinforced concrete base component 4.1 concrete and cure it to the predetermined strength;
[0061] e. Tie the reinforcing bars of the precast reinforced concrete side members 4.2;
[0062] f. Formwork for supporting precast reinforced concrete side members 4.2;
[0063] g. Pour precast reinforced concrete side members 4.2 concrete and cure to the predetermined strength;
[0064] Step 2: Place the filler 1 into the precast reinforced concrete chamber 2 and fix it as a whole;
[0065] In specific implementation, after step g, construct the precast reinforced concrete top component 4.3, according to the reinforcement of the component, set up the formwork, pour the concrete and cure it to the predetermined strength;
[0066] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications, equivalent substitutions and improvements made by those skilled in the art within the scope of the technology disclosed in the present invention should be covered within the scope of protection of the present invention.
