Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] The following is combined with Figure 1 The following describes embodiments of the present invention.

[0030] According to an embodiment of the present invention, a side beam floor slab structure is provided, comprising:

[0031] Crossbeam 1;

[0032] Template 2 includes a U-shaped plate 21 and a connecting plate 22. The opening of the U-shaped plate 21 faces upward, and the extension direction of the U-shaped plate 21 is parallel to the length direction of the crossbeam 1. The U-shaped plate 21 is located on the side of the connecting plate 22 away from the crossbeam 1, and the connecting plate 22 is fixedly connected to the crossbeam 1.

[0033] At least two side formworks are respectively set at both ends of the crossbeam 1 along its length. The side formworks are fixedly connected to the formwork 2 and / or the crossbeam 1, and together with the formwork 2 and the crossbeam 1, they form an upward-facing accommodating space. A concrete structure 3 is set in the accommodating space.

[0034] The edge beam floor slab structure provided in this embodiment is constructed as a U-shaped plate 21 and a connecting plate 22 to avoid quality problems such as weld failure and safety problems such as template detachment that are prone to occur when welding the L-shaped edge sealing plate and the side plate.

[0035] Specifically, the crossbeam 1 includes an I-beam or a box-type steel beam, etc. A U-shaped plate 21 is located on the outdoor-facing side of the crossbeam 1. Along the length of the crossbeam 1, the lengths of the U-shaped plate 21 and the connecting plate 22 are adapted to the length of the crossbeam 1. The top surface of the side wall of the U-shaped plate 21 away from the crossbeam 1 is higher than the upper end face of the crossbeam 1 and the connecting plate 22. At least two side templates are fixedly connected to the template 2 and / or the crossbeam 1 to serve as accommodating space on the side walls at both ends along the length of the crossbeam 1. The connecting plate 22 is fixedly connected to the upper or lower end face of the crossbeam 1 to seal the gap between the U-shaped plate 21 and the crossbeam 1. Compared to related technologies, where the welding of the L-shaped edge plate to the steel side plate of the I-beam is prone to detachment, the edge beam floor structure provided in this embodiment, using a U-shaped plate 21 fixedly connected to the upper or lower end face of the crossbeam 1 via the connecting plate 22, is less prone to detachment and eliminates the need for steel side plates, reducing steel consumption and providing more space for specialized construction such as curtain walls. Concrete is poured into the space through an opening above it to form concrete structure 3 after it sets. Concrete structure 3 is constructed as a bottom-reverse beam structure, meaning that the area of ​​concrete structure 3 corresponding to U-shaped plate 21 is a side beam structure, and the area corresponding to connecting plate 22 and crossbeam 1 is a floor slab structure. Formwork 2 is permanently connected to crossbeam 1 and together with concrete structure 3, forms part of the side beam floor slab structure, thereby improving the bending capacity of the side beam floor slab structure.

[0036] In one embodiment, combined Figure 1 As shown, the U-shaped plate 21 includes a first sidewall 211 and a second sidewall 212 spaced apart. The first sidewall 211 is fixedly connected to the connecting plate 22, and the second sidewall 212 is located on the side of the first sidewall 211 away from the connecting plate 22. The height of the second sidewall 212 is greater than the height of the first sidewall 211.

[0037] Specifically, the first sidewall 211 and the second sidewall 212 are spaced apart in the horizontal direction. The U-shaped plate 21 also includes a base plate fixedly connected between the first sidewall 211 and the second sidewall 212. The main plane of the base plate is parallel to the horizontal direction. The bottom end of the first sidewall 211 and the bottom end of the second sidewall 212 are on the same horizontal plane. The upper end of the second sidewall 212 is higher than the upper end of the first sidewall 211 and higher than the upper end of the connecting plate 22 and the connecting plate 22.

[0038] In one embodiment, combined Figure 1As shown, the edge beam floor structure also includes a tie rod 5. One end of the tie rod 5 is fixedly connected to the top of the second side wall 212, and the other end is fixedly connected to the connection between the first side wall 211 and the connecting plate 22.

[0039] The side beam floor structure provided in this embodiment is fixedly connected to the top of the second side wall 212 at one end of the tie rod 5, and fixedly connected to the connection between the first side wall 211 and the connecting plate 22 at the other end, so that the formwork 2 can better resist the lateral pressure generated when pouring concrete into the accommodating space.

[0040] Specifically, one end of the tie rod 5 is fixedly connected to the top of the second side wall 212 to better resist the lateral pressure generated during concrete pouring, forming a more robust and reliable structure. Preferably, there are multiple tie rods 5, spaced apart along the length of the beam 1.

[0041] In one embodiment, combined Figure 1 As shown, a bend 2121 is provided at the top of the second sidewall 212, and the bend 2121 abuts against the upper end face of the concrete structure 3.

[0042] The edge beam floor slab structure provided in this embodiment enhances the connection reliability between the formwork 2 and the concrete structure 3 by having the bent part 2121 abut against the upper end surface of the concrete structure 3.

[0043] Specifically, the bent portion 2121 can be plate-shaped or rod-shaped, and extends along one side toward the crossbeam 1. There is at least one bent portion 2121, and when there are multiple bent portions 2121, they are spaced apart along the length direction of the crossbeam 1. As a possible embodiment, the length direction of the bent portion 2121 is perpendicular to the main plane of the second sidewall 212.

[0044] In one embodiment, combined Figure 1 As shown, the edge beam floor slab structure also includes a support structure 4, which abuts against the lower end face of the template 2 and is fixedly connected to the crossbeam 1.

[0045] The edge beam floor structure provided in this embodiment provides support for the formwork 2 by having the support structure 4 abut against the lower end face of the formwork 2, thereby ensuring the connection stability between the formwork 2 and the beam 1 when pouring concrete into the accommodating space.

[0046] Specifically, the support structure 4 abuts against the lower end face of the base plate of the U-shaped plate 21. Preferably, there are multiple support structures 4, which are spaced apart along the length of the crossbeam 1.

[0047] In one embodiment, combined Figure 1 As shown, the support structure 4 includes a fixing plate 41, which is bolted to the crossbeam 1.

[0048] The side beam floor structure provided in this embodiment has the support structure 4 bolted to the cross beam 1 to facilitate the assembly and disassembly of the support structure 4, thereby enabling the cyclical use of the support structure 4.

[0049] Specifically, the support structure 4 also includes a support member 42, which abuts against the lower end face of the U-shaped plate 21. The support member 42 includes a support plate, a support rod, or a support frame, etc. The support member 42 is fixedly connected to the fixing plate 41 to form a detachable connection with the crossbeam 1 through the fixing plate 41.

[0050] In one embodiment, the thickness of template 2 is 1mm-5mm.

[0051] For example, in some embodiments, the thickness of template 2 can be 1mm or 2mm or 3mm or 4mm or 5mm, or it can be a range formed by any two of the above values.

[0052] In one embodiment, combined Figure 1 As shown, template 2 includes a steel plate.

[0053] Specifically, formwork 2 includes steel plates, wooden boards, or plastic boards. Due to the advantages of steel formwork, such as high rigidity, strong stability, precise dimensional control, smooth and flat surface, no splicing, uniform color, and good appearance quality, steel plates are preferred as the material for formwork 2. Concrete and steel plates have good adhesion properties and can be reliably combined to share stress and deformation. Therefore, steel plates, as permanent formwork, can improve the bending bearing capacity of the edge beam floor structure.

[0054] In one embodiment, the surface of the steel plate is provided with a galvanized layer.

[0055] The edge beam floor structure provided in this embodiment improves the service life of the steel plate by setting a galvanized layer on the surface of the steel plate to prevent oxidation.

[0056] In one embodiment, combined Figure 1 As shown, the accommodating space is equipped with a lower inverted beam reinforcement 6 and a floor slab reinforcement 7.

[0057] The edge beam floor slab structure provided in this embodiment enhances the tensile strength of the edge beam floor slab structure by setting the lower inverted beam reinforcement 6 and the floor slab reinforcement 7, so that after the concrete in the accommodating space has solidified, they together with the concrete structure 3 form a reinforced concrete structure.

[0058] Specifically, the bottom beam reinforcement 6 is correspondingly set in the channel space of the U-shaped plate 21, and the floor slab reinforcement 7 is set above the crossbeam 1 and extends to the top of the channel space of the U-shaped plate 21.
