Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction engineering, in particular to an overhead floor anti-settlement node. Background Art
[0002] In the construction of frame structures without basements, frame beams are usually set on the first floor. Generally, backfill soil is not set on the frame beams, so a 5cm surface layer is generally set on the frame beams. Due to the different elastic moduli of the ground beam concrete and the backfill soil, the settlement heights of the beam concrete and the backfill soil are also different. The frame beams between the columns divide the ground into several small areas, and the rigid ground with steel bars inside is also divided into small areas, resulting in poor integrity of the rigid ground. Because the rigid ground with steel bars inside cannot pass through the ground above the frame beams, the ground above the frame beams is very easy to crack, affecting the construction effect.
[0003] In the prior art, the rigid ground is designed as a whole piece. However, due to the different elastic moduli of the ground beam concrete and the backfill soil, the settlement heights of the beam concrete and the backfill soil are also different, forming a cavity between the rigid ground and the frame beam. The rigid ground above the frame beam has no support, which can easily cause the rigid ground above the frame beam to collapse. Utility Model Content
[0004] Therefore, the technical problem to be solved by the utility model is to overcome the defect of the prior art that the ground is easy to crack, thereby providing an elevated floor anti-settlement node.
[0005] The utility model provides an overhead floor anti-settling node, comprising:
[0006] Rigid ground;
[0007] There are a plurality of steel frame beams; backfill soil is arranged between adjacent steel frame beams;
[0008] The elastic structure is arranged between the steel frame beam and the rigid ground.
[0009] As a preferred solution, the elastic structure comprises a polystyrene board.
[0010] As a preferred solution, the elastic structure is fixed on the top of the steel frame beam.
[0011] As a preferred solution, the elastic structure is fixedly connected to the steel frame beam via anchor bolts.
[0012] As a preferred solution, the specifications of the anchor bolt are 8 mm in diameter and 100 mm in length.
[0013] As a preferred solution, the spacing between adjacent anchor bolts is not less than 500 mm.
[0014] As a preferred solution, the thickness of the elastic structure is 50 mm.
[0015] The technical solution of the utility model has the following advantages:
[0016] 1. The utility model provides an anti-settlement node for an elevated floor, comprising: a rigid ground, and an elastic structure, wherein the elastic structure is arranged between the steel frame beam and the rigid ground. The elastic structure can be arranged to fill the cavity formed between the rigid ground and the frame beam, and the elastic structure is added to the ground beam to play a buffering role for the rigid ground, thereby preventing the ground from slowly settling and causing cracks in the ground. The arrangement avoids the rigid ground above the frame beam from being without support, thereby preventing collapse. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0024] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0025] like Figure 1 As shown, the utility model provides an overhead floor anti-settlement node, including: a rigid ground 1, and an elastic structure 3, wherein the elastic structure 3 is arranged between the steel frame beam 2 and the rigid ground 1. There are a plurality of steel frame beams 2, and backfill soil is arranged between adjacent steel frame beams 2; the elastic structure 3 can be arranged to fill the cavity formed between the rigid ground 1 and the frame beam, and the elastic structure 3 is added to the ground beam to play a buffering role for the rigid ground 1, preventing the ground from slowly settling and causing ground cracks. The arrangement avoids the rigid ground 1 above the frame beam from being without support, thereby preventing collapse.
[0026] It should be noted that the size and reinforcement of the frame beam are based on engineering design. In this embodiment, the position of the frame beam is 5 cm below the rigid ground 1.
[0027] It should be noted that the construction process of the rigid floor 1 includes cleaning the base, nailing horizontal piles (drawing horizontal lines), concrete mixing, concrete laying, concrete cushion maintenance, and acceptance. In order to increase the life of the rigid floor 1, steel bars are implanted in the concrete. In this embodiment, the rigid floor 1 is a complete floor.
[0028] Furthermore, the elastic structure 3 is made of a high-density elastic material, and in this embodiment, a polystyrene board is selected; the polystyrene board is also known as a foam board or EPS board. It is a white solid with a fine closed-cell structure made of expandable polystyrene beads containing a volatile liquid foaming agent, which is pre-heated and then heated and formed in a mold. The polystyrene board has high strength and compressive resistance. In actual use, most of the load of the rigid ground 1 is dispersed to the backfill soil, where the area of the elastic material is the same as the area of the top of the steel frame beam 2. The bearing area of the top of the steel frame beam 2 is small, so the steel frame beam 2 only bears a small amount of load. After calculation, the load on the steel frame beam 2 will not affect the normal use of the steel frame beam 2.
[0029] Furthermore, the elastic structure 3 is fixed on the top of the steel frame beam 2. If the elastic structure 3 is misaligned, a cavity will appear between the rigid ground 1 and the steel frame beam 2, which may easily cause ground subsidence. Specifically, the fixing method includes bonding and welding. In this embodiment, the elastic structure 3 is fixedly connected to the steel frame beam 2 by anchor bolts 4. By setting the anchor bolts 4, the elastic structure 3 can be prevented from shifting during the construction process. In this embodiment, the specifications of the anchor bolts 4 are 8 mm in diameter and 100 mm in length, and the spacing between adjacent anchor bolts 4 is not less than 500 mm.
[0030] Furthermore, in this embodiment, the thickness of the elastic structure 3 is 50 mm. It should be noted that the thickness of the elastic structure 3 is generally determined according to the cavity formed between the rigid ground 1 and the frame beam. In this embodiment, the width of the elastic structure 3 is the same as the width of the frame beam.
[0031] In this embodiment, after the frame beams reach the design strength, backfill is performed between the frame beams. After the backfill is completed, the elastic structure 3 is fixed to the frame beams with anchor bolts 4, a cushion layer is poured at the backfill position, and finally the rigid ground 1 is constructed.
[0032] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
