Description

Technical Field

[0001] This utility model relates to the field of building construction, and specifically refers to a glass fiber reinforced concrete beam-slab space frame structure. Background Technology

[0002] As construction projects increasingly move towards larger spans and higher floors, and with continuous technological exploration, people's requirements for the built environment are becoming more and more specific, and they are increasingly pursuing sustainable development. These are ultimately reflected in material requirements. As a material that can replace traditional steel bars, glass fiber reinforced concrete is being used more and more widely in fields such as large-span structures, military industry, marine chemical environments, medical equipment rooms, and laboratories, thanks to its lightweight, high strength, corrosion resistance, non-magnetic, and environmentally friendly characteristics.

[0003] The use of glass fiber reinforced concrete (GFRP) bars is to meet the requirements of the building environment, which also means that they cannot adopt the same connection structure as conventional steel bars. For example, in the construction of beam and slab space frames, it is necessary to set up stirrups as supports between the upper and lower stirrups. However, stirrups made of traditional steel bars cannot meet the requirements of the building environment, and it is more difficult to process GFRP bars into stirrups, thus making them unsuitable for conventional building beam and slab construction. Summary of the Invention

[0004] The purpose of this utility model is to overcome the defects of the prior art and provide a glass fiber reinforced concrete beam and slab grid structure, which solves the problem that glass fiber reinforcement cannot be directly applied to conventional beam and slab construction in the prior art.

[0005] To achieve the above objectives, this utility model provides a glass fiber reinforced concrete beam-slab space frame structure, including a first steel mesh, a second steel mesh, U-shaped bars, a first tie rope, and a second tie rope;

[0006] Both the first and second steel meshes include mutually perpendicular X-direction and Y-direction reinforcements, and the nodes of the X-direction and Y-direction reinforcements of the second and first steel meshes are vertically aligned.

[0007] The two U-shaped bars are arranged in a staggered manner and face each other. The bottom of the two U-shaped bars are connected to the X-direction and Y-direction bar nodes of the first steel mesh through the first tie rope.

[0008] The tops of the two U-shaped bars are connected to the X-direction and Y-direction reinforcement nodes of the second steel mesh via the second binding rope.

[0009] By adopting this technical solution, the support members used for supporting the second steel mesh on the first steel mesh are set as U-shaped bars facing each other to accommodate the bending performance of glass fiber reinforcement. After the U-shaped bars are connected to the first and second steel meshes in conjunction with the first and second tie ropes, a grid structure suitable for floor slab construction is formed, realizing the application of glass fiber reinforcement in concrete beams and slabs without affecting the requirements of the building environment.

[0010] Furthermore, it also includes a third binding rope; the X-direction and Y-direction reinforcements of the first and second steel mesh are tied together at their intersections using the third binding rope.

[0011] By adopting this technical solution, a basic and stable steel mesh structure is formed.

[0012] Furthermore, the U-shaped reinforcement is made of the same material as the first and second steel mesh, which is glass fiber reinforcement.

[0013] By adopting this technical solution, it is ensured that the constructed beam-slab space frame structure will not affect the corrosion resistance, non-magnetic properties, and environmental friendliness of the glass fiber reinforcement itself, and the overall weight of the beam-slab space frame can be reduced, thereby reducing the difficulty of adjustment.

[0014] Furthermore, the bottoms of the two U-shaped bars are engaged with the X-direction and Y-direction bar nodes of the first steel mesh.

[0015] By adopting this technical solution, the stability of the connection between the U-shaped bar and the X-direction and Y-direction bars of the first steel mesh can be increased, and the overturning of the U-shaped bar after connection can be avoided, which would affect the efficiency of the connection of the second steel mesh.

[0016] Furthermore, the tops of the two U-shaped bars are jointly supported at the bottom of the X-direction and Y-direction bar nodes of the second steel mesh.

[0017] By adopting this technical solution, the contact area between the U-shaped reinforcement and the X-direction and Y-direction reinforcement of the second steel mesh is increased, thereby increasing the stability after they are connected.

[0018] Furthermore, the first, second, and third cable ties are all non-metallic cable ties.

[0019] By adopting this technical solution, the problems of corrosion and magnetization caused by using conventional metal cable ties such as iron wire are avoided, which contradicts the purpose of using fiberglass reinforcement.

[0020] Compared with the prior art, this utility model has the following advantages:

[0021] The support members used for supporting the second steel mesh on the first steel mesh are set as U-shaped bars facing each other to accommodate the bending performance of glass fiber reinforcement. After the U-shaped bars are connected to the first and second steel meshes in conjunction with the first and second tie ropes, a grid structure suitable for floor slab construction is formed, realizing the application of glass fiber reinforcement in concrete beams and slabs without affecting the requirements of the building environment.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Please see the appendix Figure 1-2This utility model provides a glass fiber reinforced concrete beam-slab grid structure, including a first steel mesh 1, a second steel mesh 2, U-shaped bars 3, a first binding rope 4, and a second binding rope. Both the first and second steel meshes 1 and 2 include mutually perpendicular X-direction and Y-direction bars, with the X-direction and Y-direction bar nodes of the second and first steel meshes 2 and 1 aligned vertically. Two U-shaped bars 3 are staggered and facing each other, with their bottoms connected to the X-direction and Y-direction bar nodes of the first steel mesh 1 via the first binding rope 4. Connection; the tops of the two U-shaped bars 3 are connected to the X-direction and Y-direction bar nodes of the second steel mesh 2 through the second tie rope; the support members used for supporting the second steel mesh 2 on the first steel mesh 1 are set as U-shaped bars 3 facing each other to accommodate the bending performance of glass fiber reinforcement. After the U-shaped bars 3 are connected to the first steel mesh 1 and the second steel mesh 2 in conjunction with the first tie rope 4 and the second tie rope, a grid structure suitable for floor slab construction is formed, realizing the application of glass fiber reinforcement in concrete beams and slabs without affecting the requirements of the building environment.

[0031] Furthermore, it also includes a third tie rope; the X-direction and Y-direction reinforcements of the first steel mesh 1 and the second steel mesh 2 are all tied together by the third tie rope at the intersection positions to form a basic and stable steel mesh structure.

[0032] Furthermore, the U-shaped reinforcement 3 is made of the same material as the first steel mesh 1 and the second steel mesh 2, which is glass fiber reinforcement; this ensures that the beam-slab space frame structure does not affect the corrosion resistance, non-magnetic properties and environmental friendliness of the glass fiber reinforcement itself, and can reduce the overall weight of the beam-slab space frame, thereby reducing the difficulty of adjustment.

[0033] Furthermore, the bottoms of the two U-shaped bars 3 are engaged with the X-direction and Y-direction reinforcement nodes of the first steel mesh 1; this can increase the stability of the connection between the U-shaped bars 3 and the X-direction and Y-direction reinforcement nodes of the first steel mesh 1, and prevent the U-shaped bars 3 from tilting after connection, thus affecting the efficiency of the connection of the second steel mesh 2.

[0034] Furthermore, the tops of the two U-shaped bars 3 are jointly supported at the bottom of the X-direction and Y-direction bar nodes of the second steel mesh 2; this increases the contact area between the U-shaped bars 3 and the X-direction and Y-direction bar nodes of the second steel mesh 2, thereby increasing the stability after they are connected.

[0035] Furthermore, the first, second, and third cable ties are all non-metallic; this avoids the problems of corrosion and magnetization that would arise from using conventional metal cable ties such as iron wire, which contradicts the purpose of using fiberglass reinforcement.

[0036] During the construction of the space frame structure, the first steel mesh 1 is first tied and formed on the working plane. The finished effect is shown in the attached figure. Figure 3 Next, the first binding rope 4 is used to connect the U-shaped bars 3 to the first steel mesh 1. The finished result is shown in the attached figure. Figure 4 Subsequently, concrete blocks were laid at the bottom of the first steel mesh 1 to elevate it, and the finished effect is shown in the attached figure. Figure 5 Finally, the second steel mesh 2 is formed by binding the top of the U-shaped reinforcement 3 together with the top of the reinforcement 3. At the same time, the second steel mesh 2 is connected to the top of the U-shaped reinforcement 3 with the second tie rope to complete the beam-slab space frame construction. The finished effect is shown in the attached figure. Figure 6 .

Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
