Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0020] refer to Figure 1-7 , a multi-combination steel keel, including keel connectors and keel frames. The keel connector is divided into the main part of the connector and the accessories of the connector. The lower side of the keel frame and the connector accessory slope is welded through the main keel welding port (13), and is connected into one main keel. Both ends of the bottom of the main part of the connector are provided with snap-in units of the main part, and each snap-in unit of the main part includes a tongue groove (6), a fixed tongue convex groove (7), a tongue stopper (8), and a snap tongue (12). A concave shelf (5) is provided in the middle of th...

Abstract

The invention relates to the technical field of buildings, in particular to a multi-combination steel keel. The multi-combination steel keel comprises a keel connecting piece main part, a keel connecting piece accessory and a keel frame. Clamping tongues are separately arranged at both ends of the bottom of the keel connecting piece main part, and clamping tongue grooves are formed in the bottom of the keel connecting piece accessory. The keel frame is in a U shape, and nail grooves are formed in the bottom of the keel frame. The end with a low slope of the keel connecting piece accessory is welded to one end of the keel frame to be connected integrally to form a main keel. When combination, the keel connecting piece main part is inserted and abuts against a downward concave baffle pier from the end with a high slope of the keel connecting piece accessory, and the clamping tongues bounce into the clamping tongue grooves to complete the combination.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a multi-combined steel keel. Background technique [0002] In the field of construction, especially in the process of formwork production and installation in building construction, the amount of square wood is huge. Although countries are trying to reduce the use of wood, wood is still used as the main material in some projects. During the construction process, due to the size of the building structure The diversification of square logs gradually shortens from the usual length of 4 meters. In addition to the normal deformation of wood, such as bending and cracking, after the completion of the project, the short square logs on the construction site pile up like mountains. This project has a certain impact on the quality of the project, resulting in high project cost, single overall steel keel size is single, it is difficult to deal with the diversified dimensions of the build...
