Problems solved by technology

Adopting this kind of structure requires full racks, heavy assembly and construction workload, complicated operation, and low construction efficiency; moreover, a lot of materials are wasted, such as a large number of steel pipe fasteners, wooden squares, lead wire nails, etc.
Among them, the waste of wood is the most serious, and there are phenomena such as non-compliance with construction requirements and random sawing, difficult on-site management, and great fire hazards

Embodiment 1

[0020] Such as Figure 1-5 As shown, the plug-in main keel for construction of the present invention includes a main keel base 1, and the main keel base is composed of an upper top plate 101, a lower bottom plate 102, a left side plate 103, a right side plate 104, a front end plate 105 and a rear end plate 106 forms a hollow rectangular parallelepiped structure, and two inclined reinforcing ribs 201 and 202 are arranged symmetrically inside the main keel base 1, and one side of the reinforcing ribs 201 and 202 is respectively connected to the upper roof 101 , the other sides of the rib plates 201 and 202 are respectively connected to the lower bottom plate 102, and the two rib plates 201 and 202 form a “V”-shaped structure.

[0021] Two first installation grooves 5 extending along the length direction of the main keel base 1 are provided on the upper top plate 101 , and the cross-section of the first installation grooves 5 is a wedge-shaped structure. On the left side plate 1...

Embodiment 2

[0025] Such as figure 1 As shown, the structure of the plug-in main keel for construction in this embodiment is basically the same as that of Embodiment 1, except that the cross-section of the first installation groove 5 is Shaped structure, the cross-section of the second installation groove 6 is shape structure, such as Image 6 shown.

Abstract

The invention provides a plug-in main keel for construction, which includes a main keel base body, and the main keel base body is surrounded by an upper top plate, a lower bottom plate, a left side plate, a right side plate, a front end plate and a rear end plate to form a hollow cuboid structure , two inclined stiffener plates are arranged symmetrically inside the main keel base, one side of the stiffener plate is connected with the upper top plate, and the other side of the stiffener plate is connected with the lower bottom plate , the two stiffener plates form a "V"-shaped structure. The front end plate of the main keel base is provided with an insertion falcon, and the rear end plate of the main keel base is provided with an insertion slot matching the shape of the insertion falcon. The plug-in main keel for building of the present invention has the advantages of simple structure, light weight, easy installation and convenient length adjustment.

Description

technical field [0001] The invention belongs to the technical field of main keels, and in particular relates to a plug-in main keel for construction used in roof formwork. Background technique [0002] In the traditional construction technology, the roof formwork support system usually adopts a combination of wood formwork, wood squares and steel pipe supports. Adopting this kind of structure requires full racks, heavy assembly and construction workload, complicated operation, and low construction efficiency; moreover, a lot of materials are wasted, such as a large number of steel pipe fasteners, wooden squares, lead wire nails, etc. Among them, the waste of wood is the most serious. There are phenomena of non-compliance with construction requirements and random sawing. On-site management is difficult and fire hazards are great. In addition, because this construction technology is a combination of steel pipe and wooden square, the iron pipe is round, and the force-bearing a...
