Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel structures, and specifically relates to a steel structure cross beam. Background Art
[0002] The steel structure cross beam includes a plurality of single beams. There are connecting flanges at the end parts of the single beams. Adjacent single beams are connected by flanges and screws passing through the flanges, so that adjacent single beams form an integral steel structure cross beam. Generally, heavy materials such as rooftops are placed on the steel structure cross beam.
[0003] In the prior art, the connecting flange at the end part of the single beam is single, so there is only one set of screws connecting the flanges, which has the disadvantage of poor connection firmness and affects the bearing strength of the steel structure cross beam. Summary of the Invention
[0004] The purpose of the utility model is to provide a double-connected steel structure cross beam with strong connection firmness and high bearing strength of the steel structure cross beam in view of the above disadvantages.
[0005] The technical solution of the utility model is realized as follows: A double-connected steel structure cross beam includes a plurality of single beams. There are connecting flanges at the end parts of the single beams. Adjacent single beams are connected by flanges and screws passing through the flanges, so that adjacent single beams form an integral steel structure cross beam. The feature is that there are at least two sets of flanges at the end of each single beam, namely a first flange close to the end of the single beam and a second flange far from the end of the single beam; a set of screws are used to connect adjacent single beam ends through the first flanges. This set of screws is the first set of screws, and the screws inside the first set of screws are the first screws; and another set of screws are used to connect adjacent single beam ends through the second flanges. This set of screws is the second set of screws, and the screws inside the second set of screws are the second screws.
[0006] Furthermore, on the outer periphery of the single beam end, the first set of screws and the second set of screws are arranged at intervals, that is, on the outer periphery of the single beam end, the first screws and the second screws are arranged at intervals.
[0007] Furthermore, the inside of the single beam end has a hollow core, and there is a reinforcing ring integrated with it inside the hollow core. The reinforcing ring and the second flange are arranged corresponding to each other inside and outside.
[0008] Furthermore, the distance between the first flange and the second flange is greater than or equal to the height of the single beam.
[0009] The beneficial effect of the utility model is that such a double-connected steel structure cross beam has the advantages of strong connection firmness and high bearing strength of the steel structure cross beam. Description of the Drawings

[0014] L - the distance between the first flange and the second flange, H - the height of the single beam. Specific embodiments
[0015] The present utility model will be further described below with reference to the accompanying drawings.
[0016] As Figure 1 , 2 , as shown in Fig. 3, the double - connected steel - structure cross beam includes a plurality of single beams 1. Connecting flanges 2 are provided at the end parts of the single beams. Adjacent single beams are connected by flanges and screws 3 passing through the flanges, so that adjacent single beams form an integral steel - structure cross beam. Its characteristics are: at least two groups of flanges are provided at the end of each single beam, namely the first flange 21 close to the end of the single beam and the second flange 22 far from the end of the single beam; one group of screws is used to connect together through the first flanges at the ends of adjacent single beams. This group of screws is the first group of screws, and the screws inside the first group of screws are the first screws 31; and another group of screws is used to connect together through the second flanges at the ends of adjacent single beams. This group of screws is the second group of screws, and the screws inside the second group of screws are the second screws 32.
[0017] Since the present utility model is provided with multiple groups of connected flanges and connected screws, the steel - structure cross beam can bear higher strength, thus achieving the purpose of the present utility model.
[0018] Furthermore, on the outer periphery of the end of the single beam, the first group of screws and the second group of screws are arranged at intervals, that is, on the outer periphery of the end of the single beam, the first screws and the second screws are arranged at intervals.
[0019] With such an arrangement of the present utility model, it also has the advantage of bearing higher strength.
[0020] Furthermore, there is a hollow core 11 inside the end of the single beam, and there is also a reinforcing ring 4 integrated with it inside the hollow core. The reinforcing ring and the second flange are arranged corresponding to each other inside and outside.
[0021] With such a setting of the present utility model, it also has the advantage of higher bearing strength.
[0022] Furthermore, the distance L between the first flange and the second flange is greater than or equal to the height H of the single beam.
[0023] With such a setting of the present utility model, the function of the second flange is ensured.
[0024] The above are only specific embodiments of the present utility model, but the structural features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
