Abstract
The utility model discloses a connected node that is used for increasing equipment that hangs under concrete beam having, include the board that has had concrete beam, concrete beam both sides, its characterized in that: still include upper portion steel sheet, the support of lower part steel, upper portion steel sheet setting is in the top that has concrete beam, lower part steel holds in the palm and sets up in concrete beam's below, and the lower part steel holds in the palm including upper limb listrium, bottom wing listrium, web and stiffening rib, and suitable position pore -forming on the board that has the concrete beam both sides, bolt pass upper portion steel sheet and upper limb listrium and fix the support of lower part steel in the below that has concrete beam, bolt fastening track roof beam is passed through to the below of bottom wing listrium. The utility model discloses an advantage: because not in roof beam sidetracking hole, so the intensity of roof beam itself can not reduce. Can not make the roof beam produce the moment of torsion, more can not appear having avoided the trouble that increases additional transverse reinforcement because concentrate loading at roof beam lower part or cross -sectional height within range and the shear strength who leads to is not enough yet.
Description
Technical field
The utility model relates to building field, specifically a kind of connected node for increasing suspension equipment under existing concrete beam.
Background technology
In the industrial premises of concrete structure, due to the improvement of technology, often need to transform structure, such as, in existing factory building, increase the suspension equipments such as electric block newly.Rail beam is now needed to be connected on existing concrete beam.Conveniently way is generally by burying upper steel plate embedded part in beam sides boring, being then connected with steel plate by rail beam.Because imposed load acts on below top surface of the beam, need to increase opposing the additional of shearing and hang muscle or additional hooping, construct more difficult.And in beam sidetracking hole, operating space is limited, bad construction.In beam, reinforcing bar is close, easily destroys principal rod in beam body.Especially, when concrete beam cross section is less, the problems referred to above can be especially obvious.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of connected node for increasing suspension equipment under existing concrete beam, it can not destroy existing concrete beam body itself in rear anchoring engineering, it is stressed more reasonable to make, and more easily meets force request, and easy construction.
For solving the problem, the utility model is achieved in that
For increasing a connected node for suspension equipment under existing concrete beam, comprise the plate of existing concrete beam, concrete beam both sides, also comprise top steel plate, bottom steel rest, described top steel plate is arranged on the top of existing concrete beam; Bottom steel rest is arranged on the below of concrete beam, bottom steel rest comprises top flange plate, bottom wing listrium, web and stiffening rib, appropriate location pore-forming on the plate of existing concrete beam both sides, bottom steel rest is fixed on the below of existing concrete beam through top steel plate and top flange plate by bolt; The below of bottom wing listrium is bolted rail beam.
Bottom steel rest is formed by Plate Welding, and namely top flange plate, bottom wing listrium, web and stiffening rib are welded and fixed all-in-one-piece.
According to actual conditions in transformation, appropriate location pore-forming on the plate of existing concrete beam both sides, upper lower steel plate correspondence position preformed hole.Bolt is penetrated in hole, bolt tightening is made the existing concrete beam of upper and lower two block plate clamping, then rail beam is linked on linkage by bolt.
The size of above-mentioned top steel plate and bottom steel rest is determined according to actual conditions and meets corresponding code requirement.
Quantity and the specification of above-mentioned bolt are determined according to actual conditions, but need arrange in existing concrete beam bilateral symmetry.
Advantage of the present utility model and effect as follows:
Owing to have employed such scheme, in transformation process, existing concrete beam beam body can not be destroyed, and due to not in beam sidetracking hole, can not produce construction crack, therefore the intensity of beam itself can not reduce.And owing to being, by linkage, newly increased load is passed to top surface of the beam by bolt, therefore beam can not be made to produce moment of torsion, more there will not be the shear strength caused within the scope of beam bottom or depth of section because of Concentrated load not enough, it also avoid the trouble increasing additional transverse steel bars.
The utility model is only punch on the plate that relative thickness is less, makes construction more convenient, stressed more reasonable.
Accompanying drawing explanation
Fig. 1 is the elevation of a kind of connected node for increasing suspension equipment under existing concrete beam of the utility model.
1. existing concrete beam in figure; 2. the plate of concrete beam both sides; 3. top steel plate; 4. bottom steel rest; 5. bolt; 6. rail beam; 41. top flange plates; 42. bottom wing listriums; 43. webs; 44. stiffening ribs.
Detailed description of the invention
The utility model is illustrated below in conjunction with accompanying drawing, as shown in Figure 1, a kind of connected node for increasing suspension equipment under existing concrete beam, comprise the plate 2 of existing concrete beam 1, concrete beam both sides, it is characterized in that: also comprise top steel plate 3, bottom steel rest 4, described top steel plate 3 is arranged on the top of existing concrete beam 1; Bottom steel rest 4 is arranged on the below of concrete beam 1, bottom steel rest 4 comprises top flange plate 41, bottom wing listrium 42, web 43 and stiffening rib 44, appropriate location pore-forming on the plate 2 of existing concrete beam both sides, bottom steel rest 4 is fixed on the below of existing concrete beam 1 through top steel plate 3 and top flange plate 41 by bolt 5; The below of bottom wing listrium 42 is bolted rail beam.
Bottom steel rest 4 is formed by Plate Welding, and namely top flange plate 41, bottom wing listrium 42, web 43 and stiffening rib 44 are welded and fixed all-in-one-piece.
During construction on the plate of existing concrete beam both sides appropriate location pore-forming, upper lower steel plate correspondence position preformed hole.Bolt is penetrated in hole, bolt tightening is made the existing concrete beam of upper and lower two block plate clamping, then rail beam is linked on linkage by bolt.And this connected node increasing suspension equipment under existing concrete beam, be concrete beam both sides afterwards plate on pore-forming, because plate thickness is relatively little, pore-forming is convenient.The load acted on rail beam passes to concrete beam end face by linkage, makes beam stress more reasonable, and does not destroy the main bearing member of structure.
