Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction engineering, in particular to a novel earthquake-resistant structural floor slab. Background Art
[0002] Floor slabs are an important component of building construction. They are mainly divided into plate floor slabs, ribbed floor slabs, well-shaped floor slabs, infinite floor slabs, corrugated steel plate composite floor slabs, etc. According to the material, they can be divided into wooden floor slabs, brick floor slabs, reinforced concrete floor slabs, etc.
[0003] Most existing floor slabs are usually solid reinforced concrete structures. In actual use, their seismic resistance is poor due to their excessive weight. If hollow structures are used to make floor slabs, after long-term use, the concrete above the hollow area will be insufficiently supported due to long-term stress and easily crack, affecting its appearance and usability. Utility Model Content
[0004] Based on this, the purpose of the present invention is to provide a new type of earthquake-resistant structural floor to solve the technical problems mentioned in the above background technology.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new type of earthquake-resistant structural floor, comprising a floor main body, a support frame connected to the interior of the floor main body, and a filling layer arranged inside the support frame, and vertical ribs and transverse ribs connected to the upper part of the interior of the floor main body.
[0006] By adopting the above technical solution, the main body of the floor slab is a hollow structure, thereby reducing its own weight. A honeycomb support frame is provided inside, and a filling layer is provided inside the support frame. The support frame is honeycomb-shaped, which neither increases the weight of the main body of the floor slab too much nor supports the hollow parts of the main body of the floor slab. The setting of the filling layer fills the hollow support frame while improving the seismic resistance, heat insulation and sound insulation performance of the main body of the floor slab. The vertical and transverse reinforcements are both HRB500E steel bars with a strength-to-yield ratio of not less than 1.25. When a certain part of the floor slab undergoes large plastic deformation or plastic hinge, the steel bars have the necessary strength under large deformation conditions to ensure the basic seismic bearing capacity of the component.
[0007] Furthermore, the floor slab body is cast with 425 cement, and the support frame is made of PVC material.
[0008] By adopting the above technical solution, the compressive strength, shear and tensile strength of the floor slab body cast by cement are good, and the curing time can be shortened during the production process, thereby accelerating the production progress.
[0009] Furthermore, the filling layer is made of polyurethane foam material, and the support frame is honeycomb-shaped.
[0010] By adopting the above technical solution, the support frame is honeycomb-shaped, which neither increases the weight of the floor body too much nor can it support the hollow parts of the floor body. The setting of the filling layer fills the hollow support frame while improving the seismic resistance, heat insulation and sound insulation performance of the floor body.
[0011] Furthermore, the vertical and transverse reinforcements are both HRB500E steel bars.
[0012] By adopting the above technical solution, both the vertical and transverse reinforcements are HRB500E steel bars with a strength-to-yield ratio of not less than 1.25. This ensures that when large plastic deformation or plastic hinge occurs in a certain part of the floor slab, the steel bars have the necessary strength under large deformation conditions, thereby ensuring the basic seismic bearing capacity of the component.
[0013] Furthermore, the support frames and filling layers are provided in multiple groups, and the multiple groups of support frames and filling layers are distributed at equal distances.
[0014] By adopting the above technical solution, the main body of the floor slab is a hollow structure, thereby reducing its own weight. By setting up multiple sets of support frames and filling layers, the weight of the main body of the floor slab will not be increased too much, and the hollow parts of the main body of the floor slab can be supported.
[0015] Furthermore, two groups of vertical ribs and two groups of transverse ribs are provided, and the two groups of vertical ribs and transverse ribs are distributed up and down.
[0016] By adopting the above technical solution, the upper part and the lower part of the support frame can be supported respectively, thereby increasing the structural strength and improving the earthquake resistance.
[0017] Furthermore, the two groups of vertical bars are connected with tension bars, and the tension bars are in the shape of an "8", and the tension bars are formed by bending HRB400 steel bars.
[0018] By adopting the above technical solution, tension is applied to the two groups of tie bars through the tie bars, thereby ensuring the vertical spacing between the two groups of vertical bars and transverse bars, thereby avoiding deformation of the main body of the floor slab.
[0019] Furthermore, a plurality of tie bars are provided, and the plurality of tie bars are distributed in a rectangular array.
[0020] By adopting the above technical solution, the number of tension bars is increased, thereby increasing the points where tension is applied, and further improving the structural strength to ensure the vertical spacing between the two groups of vertical bars and transverse bars.
[0021] In summary, the present invention has the following beneficial effects:
[0022] 1. The utility model provides a floor slab body, a support frame, and a filling layer. The floor slab body is a hollow structure, thereby reducing its own weight. A honeycomb-shaped support frame is provided inside the support frame, and a filling layer is provided inside the support frame. The honeycomb-shaped support frame does not increase the weight of the floor slab body too much, while supporting the hollow part of the floor slab body. The filling layer fills the hollow support frame and can improve the seismic resistance, heat insulation, and sound insulation performance of the floor slab body. By reducing the self-weight, the seismic resistance is improved, and the structural strength is high. The filling layer can also further reduce shock and increase the heat insulation and sound insulation effects.
[0023] 2. The utility model uses vertical and transverse reinforcements, both of which are HRB500E steel bars with a strength-to-yield ratio of not less than 1.25. When a certain part of the floor slab undergoes large plastic deformation or plastic hinge, the steel bars have the necessary strength under the condition of large deformation, thereby ensuring the basic seismic bearing capacity of the component and further improving the seismic performance of the floor slab.

[0032] A new type of earthquake-resistant structural floor, such as Figure 1 and Figure 2As shown, it includes a floor slab main body 1, which is cast with 425 cement. A support frame 2 is connected to the inside of the floor slab main body 1. The support frame 2 is honeycomb-shaped and made of PVC material. A filling layer 3 is arranged inside the support frame 2. The filling layer 3 is made of polyurethane foam material. There are multiple groups of support frames 2 and filling layers 3, and multiple groups of support frames 2 and filling layers 3 are equidistantly distributed. The floor slab main body 1 is a hollow structure to reduce its own weight. A honeycomb-shaped support frame 2 is arranged inside the support frame 2, and a filling layer 3 is arranged inside the support frame 2. The support frame 2 is honeycomb-shaped, which will not increase the weight of the floor slab main body 1 too much, and can support the hollow part of the floor slab main body 1. The setting of the filling layer 3 fills the hollow support frame 2 while improving the seismic resistance, heat insulation and sound insulation performance of the floor slab main body 1.
[0033] See Figure 1 and Figure 3 In the above embodiment, vertical reinforcement 4 and transverse reinforcement 5 are respectively connected to the upper part of the interior of the floor slab body 1. Both the vertical reinforcement 4 and the transverse reinforcement 5 are HRB500E steel bars. Two groups of vertical reinforcement 4 and transverse reinforcement 5 are provided. The two groups of vertical reinforcement 4 and transverse reinforcement 5 are distributed up and down. Both the vertical reinforcement 4 and transverse reinforcement 5 are HRB500E steel bars with a strength-to-yield ratio of not less than 1.25. When a certain part of the floor slab undergoes large plastic deformation or plastic hinge, the steel bars have the necessary strength under large deformation conditions to ensure the basic seismic bearing capacity of the component.
[0034] Example 2:
[0035] On the basis of the above embodiment 1, in order to ensure the vertical spacing between the two groups of vertical ribs 4 and the transverse ribs 5 and avoid deformation of the floor slab body 1, the following settings are adopted.
[0036] See Figure 3 and Figure 4 In the above embodiment, a tie bar 6 is connected between the two groups of vertical bars 4. The tie bar 6 is in the shape of "8". The tie bar 6 is formed by bending HRB400 steel bars. There are multiple tie bars 6, and the multiple tie bars 6 are distributed in a rectangular array. Tension is applied to the two groups of tie bars 6 through the tie bars 6, thereby ensuring the vertical spacing between the two groups of vertical bars 4 and the transverse bars 5, thereby avoiding deformation of the floor slab body 1.
[0037] The implementation principle of the present invention is as follows: first, the support frame 2 is manufactured by extrusion or injection molding, and then polyurethane foam material is injected into the support frame 2 to form a filling layer 3. Then, the support frame 2 with the filling layer 3 and the vertical ribs 4, transverse ribs 5 and tension ribs 6 tied with iron wire are placed in a casting mold, and then 425 cement is poured to form the floor slab body 1;
[0038] The main body 1 of the floor slab is a hollow structure to reduce its own weight. A honeycomb support frame 2 is provided inside the support frame 2, and a filling layer 3 is provided inside the support frame 2. The support frame 2 is honeycomb-shaped, which will not increase the weight of the main body 1 of the floor slab too much, and can support the hollow part of the main body 1 of the floor slab. The filling layer 3 is set to fill the hollow support frame 2 while improving the seismic resistance, heat insulation and sound insulation performance of the main body 1 of the floor slab. The vertical reinforcement 4 and the transverse reinforcement 5 are both HRB500E steel bars with a strength-to-yield ratio of not less than 1.25. When a certain part of the floor slab undergoes large plastic deformation or plastic hinge, the steel bars have the necessary strength under large deformation conditions to ensure the basic seismic bearing capacity of the component. At the same time, tension is applied to the two groups of reinforcement bars 6 through the reinforcement bars 6, thereby ensuring the vertical spacing between the two groups of vertical reinforcement bars 4 and transverse reinforcement bars 5 to avoid deformation of the main body 1 of the floor slab.
