Description

Technical Field

[0001] This utility model relates to the field of beam support, and more particularly to a lightweight, bending-resistant steel-concrete composite beam reinforced beam support. Background Technology

[0002] In construction engineering, common methods of constructing supports for reinforcing steel structures include ladder supports, I-beam supports, Z-beam supports, multi-beam supports, steel pipe supports, and steel profile supports. These supports can ensure the quality of steel reinforcement forming, reduce the occurrence of common defects in reinforced concrete, and improve the appearance quality. With the continuous development of the construction industry, large-space structures have presented ultra-high, ultra-large, and ultra-long structural components. Conventional reinforced concrete structures cannot meet the structural requirements. Steel-concrete composite structures can improve the load-bearing capacity of components, reduce the bulky size of structures, and enhance the functionality of building space.

[0003] Steel profile supports are one of the technologies for spatial support of reinforcing bars. Compared with traditional steel bar supports and steel pipe supports, steel profile supports have higher load-bearing capacity, smaller deformation deflection, better seepage prevention function, and better forming quality. However, they involve a large amount of welding, are heavy (steel content), have high cost, and slow construction speed. Large transfer beams have high steel content due to dense reinforcing bars, and the cost of specially made steel profile supports is high. The specifications do not match the spacing of the reinforcing bars, and the heavy weight makes it inconvenient for workers to install. Reinforcing bar supports of the same specification have excessively wide components and large deformation deflection, which cannot meet the forming quality of the reinforcing bar skeleton. In order to ensure the forming quality of the reinforcing bar skeleton, improve construction efficiency, and reduce construction costs, it is necessary to develop a lightweight, bending-resistant steel-concrete beam reinforcing bar support to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a lightweight, bending-resistant steel-concrete beam reinforcement support to solve the problem that existing steel supports are heavy and costly, and that using steel supports of the same specifications cannot meet the requirements for the quality of the steel skeleton forming. The specific technical solution is as follows:

[0005] A lightweight, flexurally resistant steel-concrete composite beam with reinforcing bars includes several stacked and welded galvanized square tubes. The galvanized square tubes include long galvanized square tubes and short galvanized square tubes. The short galvanized square tubes are arranged on the side of the long galvanized square tubes. The number of short galvanized square tubes is N, where N is an even number. The N short galvanized square tubes are divided into two groups according to their quantity and arranged at intervals.

[0006] As an improvement to the above technical solution, the galvanized square tube has only one side concave to form a groove, and the two sides of the groove contract towards the center to form a triangular shape.

[0007] As an improvement to the above technical solution, the side of the galvanized square tube with the groove is configured as a first welding surface, and the other side of the galvanized square tube opposite to the first welding surface is configured as a second welding surface. The first welding surface of one of two adjacent galvanized square tubes is welded to the second welding surface of the other galvanized square tube.

[0008] As one of the improvements to the above technical solution, N equals 2.

[0009] As an improvement to the above technical solution, an arc surface is formed at the corner between the first welding surface and its adjacent side surface.

[0010] As an improvement to the above technical solution, the two sets of short galvanized square tubes are arranged on the same side of the long galvanized square tube.

[0011] The beneficial effects of this utility model are as follows: Compared with traditional steel brackets, galvanized square tubes are lightweight (lower steel content than steel pipes and channel steel), easier to assemble and install, have high load-bearing capacity, and can be applied to a wide range of scenarios. By dividing N short galvanized square tubes into two groups and setting them at intervals, a space will be formed between the two groups of short galvanized square tubes to facilitate installation, reduce construction costs (steel content ratio), and are low-carbon and environmentally friendly.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Of course, implementing any product or method of this application does not necessarily require achieving all of the advantages described above at the same time. Attached Figure Description

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and 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.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] Please see Figure 1-2 In this embodiment of the utility model, a lightweight, bending-resistant steel-concrete beam reinforcement support is mainly used as a longitudinal reinforcement support for the upper beam of a composite steel beam. Specifically, it includes several stacked and welded galvanized square tubes. The galvanized square tubes include long galvanized square tubes 1 and short galvanized square tubes 2. The short galvanized square tubes 2 are arranged on the side of the long galvanized square tubes 1. The number of short galvanized square tubes 2 is N, where N is an even number. The N short galvanized square tubes 2 are divided into two groups according to their quantity and are arranged at intervals. Compared with traditional steel supports, galvanized square tubes are lightweight (lower steel content than steel pipes and channel steel), easier to assemble and install, have high load-bearing capacity, and can be applied to a wide range of scenarios. Dividing the N short galvanized square tubes 2 into two groups and arranging them at intervals creates a space between the two groups of short galvanized square tubes 2 to facilitate installation.

[0020] Generally, N is at least 2 or equal to 2, and the two groups of short galvanized square tubes 2 are set on the same side of the long galvanized square tube 1. N is limited to an even number so that the multiple short galvanized square tubes 2 can be divided into two groups to ensure that the two sides are of equal width.

[0021] In some embodiments, the galvanized square tube has only one side recessed to form a groove 3, and the two sides of the groove 3 taper towards the center to form a triangular shape. By setting the groove 3, the local rigidity and overall strength are increased. In particular, when the galvanized square tube is under pressure, deformation can be effectively reduced and the bending and torsional resistance can be improved.

[0022] Regarding the welding of galvanized square tubes, the side of the galvanized square tube with groove 3 is configured as the first welding surface, and the other side of the galvanized square tube opposite to the first welding surface is configured as the second welding surface. The first welding surface of one of two adjacent galvanized square tubes is welded to the second welding surface of the other galvanized square tube.

[0023] In some embodiments, an arc surface 4 is formed at the corner between the first welding surface and its adjacent side surface. In a specific application, taking two stacked galvanized square tubes as an example, the bottom of the arc surface 4 of the upper galvanized square tube will abut against the second welding surface of the lower galvanized square tube. This abutment serves as a weld during welding. Due to the presence of the arc surface 4, a receiving groove is formed between the arc surface 4 of the upper galvanized square tube and the second welding surface of the lower galvanized square tube to receive the welding material, ensuring the flatness of the side or end face of the support beam after welding.

[0024] It should be noted that the terms "first," "second," etc., used in this document are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

[0025] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
