Installing and blocking machine and method for installing nodal points of construction steel framework by using same

Abstract

The invention relates to an installing and blocking machine and a method for installing nodal points of a construction steel framework by using the installing and blocking machine. The installing and blocking machine comprises a ground rack and a plurality of pressure single machines; each pressure single machine comprises a base clamping device which is arranged in a ground track groove in a sliding manner; two supporting rails are welded at the front part and the back part of the base clamping device and are respectively penetrated and arranged in transverse sleeve type slide rails of a first cross-shaped sliding sleeve and a second cross-shaped sliding sleeve; positioning blocks are respectively connected on the transverse sleeve type slide rails; and two pressure devices are arranged on vertical sleeve type slide rails of the first sliding sleeve and the second sliding sleeve. When the nodal points are arranged, the positions of the nodal points on a square column are adjusted on the ground track in a sliding manner through the base clamping devices; positioning grooves are arranged on second blocking seats of the pressure devices so that the nodal points are conveniently blocked and placed in the positioning grooves; the nodal points are arranged in the square column and centered through the positioning blocks on the positioning blocks on the transverse sleeve type slide rails; and finally the placed nodal points are pressurized in placed through the pressure devices, and bolts are manually screwed; the whole process is simple and convenient to operate and is accurate in installation; the labor time of workers is saved; and the working efficiency of the workers is improved.

Description

technical field [0001] The invention relates to a construction node installation device and an installation method, in particular to a card loading machine and a method for using the card loading machine to install building steel frame nodes. Background technique [0002] At present, the installation of joints in buildings is mainly through manual welding of vertical columns and beams, and the welded joints are then transported to the construction site. Due to the relatively large volume of welded joints, only one or two pieces can be loaded each time. The efficiency of this method is too low, and the stress transmission of the welded node structure is poor, and it is difficult to release and easily cause stress concentration, which is locally destructive. [0003] Such as figure 1 As shown, it is a schematic diagram of the existing building steel frame joints, including vertical columns 1', four cross-shaped I-shaped beams 2', four flexible inner connection cards 3', and f...

Problems solved by technology

[0006] The above operations are all performed manually. Since the bolt connection parts are all manually operated and must meet the pre-tightening force requirements of the node connection parts, the installation of each bolt is time-consuming and labor-intensive, and the labor intensity of the workers is low. In addition, the inner connection card 3' and When the external connection card 5' is processed and leaves the factory, the centerlines of the two connection plates 11' on each internal connection card 3' or the external connection card 5' do not coincide, see figure 2 The shape of the connecting plate 11 ' represented by double-dot dash line in

Therefore, the connecting plates 11' between each pair of internal connection cards 3' or external connection cards 5' cannot be fitted together, and external forces need to be used to pre-press the pre-tightening shoulders 13' on each pair of internal connection cards or on each external connection card. The pre-tightening shoulder 13' can make the two inner or outer connecting cards fit each other, which makes it more time-consuming and laborious to connect the inner or outer connecting cards to the beam
