Description

Technical Field

[0001] The utility model relates to the technical field of steel structure construction, in particular to a secondary construction steel column anchoring node for roofing. Background Art

[0002] In the general construction of roof steel structure column anchor nodes, the traditional method is to anchor the anchor bolts into the frame columns of the next layer.

[0003] This method requires the structural form of the roof steel structure and the steel structure manufacturer to be determined in advance. If the anchor bolts are embedded in advance, it is very likely that the embedded anchor bolts cannot be used at all. Therefore, this device introduces a method that does not require the steel structure bolts to be anchored into the frame columns of the next layer. The steel structure anchor nodes and embedded anchor bolts are constructed directly from the roof floor surface. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a secondary construction steel column anchor node for the roof, which starts the construction of the structural anchor node body and the embedded anchor bolts directly from the roof floor surface, and extends the main reinforcement of the roof layer steel frame column upward, and reserves a straight thread head at the end. After the specific form of the roof steel structure is confirmed, the embedded anchor bolts are directly welded and fixed in the anchor node body of the rental house.

[0005] The technical solution to achieve the purpose of the utility model is: a secondary construction steel column anchor node for the roof, including an anchor node main body, a plurality of pre-embedded anchor bolts are welded and fixed on the inner side of the anchor node main body, and a plurality of roof layer steel frame column main bars are arranged on the inner side of the anchor node main body, and also includes: a shear groove, which is reserved on the inner side of the anchor node main body; the upper ends of the plurality of roof layer steel frame column main bars are fixed with straight thread heads, and the outer sides of the plurality of roof layer steel frame column main bars are tied with stirrups, and the upper ends of the plurality of roof layer steel frame column main bars and stirrups are poured with cement mortar.

[0006] In some embodiments, the anti-shear groove is specifically in a cross shape.

[0007] In certain embodiments, the main reinforcement bars of the plurality of roof layer steel frame columns extend upwardly from the roof structure by 600 mm.

[0008] In some embodiments, the shear groove is reserved after pouring concrete inside the anchor node body.

[0009] In some embodiments, the plurality of straight thread wire heads are connected using a primary connector.

[0010] Compared with the prior art, the present invention has the following significant advantages:

[0011] The utility model starts the construction of the structural anchor node body and the embedded anchor bolts directly from the roof floor surface, extends the main reinforcement of the roof layer steel frame column upward, and reserves a straight thread head at the end. After the specific form of the roof steel structure is confirmed, the embedded anchor bolts are directly welded and fixed in the anchor node body of the rental house;

[0012] The problem that the existing pre-buried anchor bolts may be unusable due to premature embedding is solved. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model provides a roof secondary construction steel column anchoring node through improvement. The technical solution of the utility model is:

[0019] like Figure 1As shown, a secondary construction steel column anchor node for roofing includes an anchor node body 1, a plurality of pre-buried anchor bolts 2 are welded and fixed on the inner side of the anchor node body 1, and a plurality of main reinforcement bars 3 for roofing layer steel frame columns are arranged on the inner side of the anchor node body 1, and also includes: a shear groove 4, the shear groove 4 is reserved on the inner side of the anchor node body 1; the upper ends of the plurality of main reinforcement bars 3 for roofing layer steel frame columns are all fixed with straight thread heads 5, and the outer sides of the plurality of main reinforcement bars 3 for roofing layer steel frame columns are tied with stirrups 6, and the upper ends of the plurality of main reinforcement bars 3 for roofing layer steel frame columns and stirrups 6 are poured with cement mortar 7. During operation, the specific form of the roof steel structure is confirmed by the designer. After completing the preliminary steel structure design, four embedded anchor bolts 2 are welded and fixed in the anchor node body 1 of the roof, the stirrups 6 are tied, and then concrete is poured and shear grooves 4 are reserved. The concrete strength is the same as the lower column concrete. The bolt thread head and the straight thread thread head 5 are sealed with tape, and then cement mortar 7 is used to wrap and seal the multiple embedded anchor bolts 2 and the straight thread thread heads 5. When the roof steel structure is formally constructed, the cement mortar 7 is removed to carry out the upper steel structure construction. Through the above operations, the situation that multiple embedded anchor bolts 2 may be unusable due to pre-embedding in advance is avoided, thereby improving the economy.

[0020] like Figure 1 As shown, in one embodiment, the shear groove 4 is specifically in a cross shape.

[0021] like Figure 1 As shown, in one embodiment, the main reinforcement bars 3 of multiple roof layer steel frame columns specifically extend upward from the roof structure by 600 mm, ensuring feasibility.

[0022] like Figure 1 As shown, in one embodiment, the shear groove 4 is reserved after pouring concrete inside the anchor node body 1 .

[0023] like Figure 1 As shown, in one embodiment, a plurality of straight threaded wire heads 5 are specifically connected by a primary joint, and subsequently a plurality of main reinforcement bars 3 of the roof layer steel frame columns can be extended by a straight threaded joint.

[0024] The specific working method is: extend the main reinforcement 3 of multiple roof layer steel frame columns upward by 600mm from the roof structure, and reserve straight threaded thread heads 5 at the ends. Multiple straight threaded thread heads 5 are all connected by first-level joints. Straight threaded joints can be used to extend the main reinforcement 3 of multiple roof layer steel frame columns later. After the design confirms the specific form of the roof steel structure and completes the preliminary steel structure design, four pre-buried anchor bolts 2 are welded and fixed in the anchor node body 1 of the roof, and the stirrups 6 are tied. Then, concrete is poured and shear grooves 4 are reserved. The concrete strength is the same as that of the lower column concrete. The bolt thread heads and straight threaded thread heads 5 are sealed with tape, and then cement mortar 7 is used to wrap and seal the space between the multiple pre-buried anchor bolts 2 and the straight threaded thread heads 5. When the roof steel structure is formally constructed, the cement mortar 7 is removed to carry out the upper steel structure construction. Through the above operations, the situation that multiple pre-buried anchor bolts 2 may be unusable due to pre-buried in advance is avoided, thereby improving the economy.

[0025] The technical means disclosed in the utility model are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacement of the above technical features. Matters not covered in the utility model belong to the common knowledge of those skilled in the art.
