Description

Split bolt assembly

Technical Field

The utility model relates to a construction technical field especially relates to a split bolt subassembly.

Background

In the construction process of the concrete in the building field, the template is a key process for enabling the concrete to be in a line according to the designed shape, and in order to enable the concrete to achieve the effects of smooth surface, no slurry leakage and no formwork leakage after formwork removal, the installation and fixation of the template play a decisive role. In the current building construction, the split bolt is used for the drawknot between the inner and outer templates of the wall or beam body to bear the lateral pressure and other loads of concrete, so as to ensure that the space between the inner and outer templates can meet the design requirements, and is also the fulcrum of the template and the supporting structure thereof. The split screw is generally arranged at the part of the beam template which needs to be reinforced, and can play a good fixing effect on the template installation of the structural member with a larger section. For the installation of the template of the structural member with a smaller section, the split bolt is not suitable for being adopted, and the cost and the labor force are increased. Especially for the fixing of the upper opening of the beam mould, the position is not suitable for the reason that only one side of the position can be fixed by punching, and the two sides of the common split screw rod are fixed by punching, so the method is not suitable.

At present, the upper opening of the beam formwork is generally fixed by tightening an iron wire, but the tightening and fixing of the iron wire requires that an operator has good operation proficiency, and the iron wire is easy to pull to cause damage to the surface of concrete in the form removal process to affect the quality.

When the later-stage template is detached, the protruding part of the screw rod is cut and leveled by a hand grinding tool. This split bolt subassembly simple structure not only can reach conventional split bolt's effect, and installation operation process is also simple relatively simultaneously, can not produce the taut concrete defect problem of handling of iron wire after the form removal yet.

Furthermore, the diameter range of the screw rod is 8-14 mm.

The diameter of the wire rod is selected to be determined by the cross-sectional dimensions of the structural member.

Further, the pull rod is a round steel bar.

Because the reinforcing bar waste material that the job site produced is more, so this split bolt subassembly can be with the reinforcing bar waste material recovery of on-the-spot production of recycling to reduced the manufacturing cost of split bolt subassembly, also improved the efficiency of construction on-the-spot simultaneously.

Furthermore, the diameter range of the pull rod is 6-14 mm.

The diameter of the pull rod is selected based on the cross-sectional dimensions of the structural member.

Further, the pull rod is welded on the position, close to the end, of the screw rod.

Further, the mounting plate is a square iron sheet.

Further, the external dimensions of the mounting plate are: 40mm by 40 mm.

Furthermore, the mounting plate is welded on the position, close to the end, of the pull rod and is parallel to the pull rod.

Further, still include a waterstop piece, the waterstop piece sets up on the lead screw.

Through setting up the stagnant water piece, can effectively prevent the seepage along lead screw and concrete junction such as aqueous vapor, and the stagnant water effect in the work progress is better.

To sum up, the utility model provides a pair of split bolt subassembly has following technological effect:

1) the utility model provides a to drawing bolt assembly, simple structure not only can reach conventional effect to drawing bolt, and installation operation process is also simple relatively simultaneously, can not produce the taut concrete defect problem of handling of iron wire after the form removal yet, has great practicality.

2) The utility model provides a to drawing bolt assembly can retrieve the reinforcing bar waste material that the scene produced and make the pull rod to greatly reduced the manufacturing cost to drawing bolt assembly, also improved the efficiency of construction on-the-spot simultaneously.
