Description
Technical Field
The utility model relates to a steel construction building field, especially a connection structure of steel davit and concrete beam.
Background
Traditional steel davit is connected with upper portion concrete beam, generally is fixed in the concrete beam bottom through reverse chemical crab-bolt with the connecting plate, then welds the connecting plate with steel davit top again. This approach has two drawbacks: (1) when the chemical anchor bolt is reversely fixed, the anchoring quality is difficult to ensure due to the self-weight effect; (2) and the longitudinal stressed steel bars at the lower part of the concrete beam can be damaged to a great extent during drilling, so that the bearing capacity of the concrete beam is reduced. Meanwhile, the operation requirement on constructors is high, and the actual construction difficulty is high.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a connection structure of a steel hanging column and a concrete beam.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a connection structure of steel davit and concrete beam, includes concrete beam and steel davit, concrete beam includes horizontal part and the vertical portion of downside, the steel sheet of vertical installation is installed through the chemical crab-bolt of wearing that the level set up in the vertical part left and right sides of concrete beam, the welding has the connection support between the steel sheet downside, the connection support downside hangs the column connection through bolt and steel, wherein the connection support from the top down is in proper order including roof, the vertical bottom plate that is provided with biography power board, level that the level set up.
As a preferred item, the reinforcing plate is distributed on the force transmission plate.
The utility model has the advantages that: through the design of horizontal drilling access to wearing chemical crab-bolt to connect concrete beam and steel sheet, steel sheet and connection support connection steel davit, avoid haring concrete beam and atress reinforcing bar, improve concrete beam bearing capacity, simple manufacture, the construction of being convenient for moreover, economic benefits is good.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a right side view at section AA in FIG. 1;
fig. 3 is a top view at BB section in fig. 1.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. Rather, the invention can be practiced without these specific details, i.e., those skilled in the art can more effectively describe the nature of their work to others skilled in the art using the description and illustrations herein.
Referring to fig. 1, a connection structure of steel davit and concrete beam, including concrete beam 1 and steel davit 2, concrete beam 1 includes horizontal part 11 and the vertical part 12 of downside, and concrete beam 1 forms a T font structure promptly, specifically forms through concrete integrated into one piece, and concrete manufacturing process is no longer repeated.
Referring to fig. 1 and 2, the steel plates 4 which are vertically installed are installed on the left side and the right side of the vertical part 12 of the concrete beam 1 through the oppositely penetrating chemical anchor bolts 3 which are horizontally arranged, the oppositely penetrating bolts can achieve the tensile and shearing resistant effects by means of methods such as fastening of the steel plates 4 which penetrate through the concrete beam 1 and the two sides and matching with nut backing plates, the chemical anchor bolts are matched with the characteristic that expansion and extrusion stress does not exist on a base material, and the damage to the concrete beam is reduced. The welding has connection support 5 between 4 downside of steel sheet, wherein refer to fig. 1, fig. 3, connection support 5 downside passes through bolt 6 and is connected with steel davit 2, wherein connection support 5 from the top down is including roof 51, the vertical bottom plate 53 that is provided with dowel plate 52, the level setting that sets up of level that the level set up in proper order, accomplishes the biography power system of steel davit 2 and concrete beam 1, and this kind of design can further reduce the stress concentration degree to concrete beam 1 especially vertical part 12, further reduces the damage of concrete beam.
The reinforcing plate 54 is distributed on the force transmission plate 52, so that the structural strength of the force transmission plate 52 is improved. Alternatively, the reinforcing plate 54 is a straight plate structure vertically distributed on the force transmission plate 52, and forms a cross-shaped structure with the force transmission plate 52.
According to the above principle, the present invention can also make appropriate changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should fall within the protection scope of the claims of the present invention.
Practice proves that good nodes are reasonable points of stress, and the nodes are clearly designed in the structure, so that the force can be effectively transmitted in the structure, and the mechanical properties of all members can be effectively exerted. Compared with the prior art, the design has the advantages that:
(1) the chemical anchor bolt is a horizontal drilling hole, the conventional method of reversely drilling from the bottom of the beam is changed, the positioning is more accurate, the drilling is more convenient, the anchoring quality is more ensured, the stressed steel bar of the concrete beam is prevented from being damaged, and the influence on the bearing capacity of the concrete beam is minimum;
(2) the steel plates on the two sides of the concrete beam are mainly tensioned and cut, the mechanical property of the concrete beam is fully exerted, the steel plates are tightened by the anchor bolts, the bearing capacity of the concrete beam is effectively improved, and the adverse effect of the additional hanging columns on the main structure is improved;
(3) the connecting support is used as a transition support of the upper concrete beam and the lower steel suspension post and is connected through the high-strength bolt, construction is simple and convenient, operation is easy, the connection belongs to a flexible connection mode, the anti-seismic performance is good, the high-strength bolt is pulled in the bolt rod shaft direction, excellent tensile performance can be fully exerted, and safety is higher.
