Description
Technical Field
The utility model relates to a strutting arrangement specifically is a two T plate rib and support reinforcing strutting arrangement between girder steel.
Background
The double T-shaped plate consists of a wide panel and two narrow and high ribs, has good structural mechanical property, definite force transmission level and simple geometric shape, and is widely applied to roofs and floor systems of large-span industrial plants and civil buildings. The current construction mode is as follows: after a plurality of double T plates are assembled and connected into a roof or a floor, the lower parts of double T plate ribs below the same horizontal line are connected with a transverse supporting steel beam and a vertical supporting rod fixed on the foundation surface in a supporting way along the width direction of the panel.
However, the double-T plate has a smaller cross section and a thinner wall thickness, so that the bearing capacity is relatively small, the safety reserve is very limited, when the waterproof layer of the roof or the floor is damaged and leaks to absorb water or meets rainy and snowy weather, the weight of the surface layer is increased, the borne load exceeds the designed load, the situations of overlarge deflection and the like are easy to occur, and further, the dangers of fracture, collapse and the like of the roof or the floor exist. Therefore, the whole dismantling and replacing of the double-T plate roof and the floor system are always carried out, the cost is high, and the normal use inside the building is influenced.
Disclosure of Invention
An object of the utility model is to provide a two T board ribs and support reinforcing strutting arrangement between girder steel have realized the reinforcement to two T boards under the condition of not demolising the primary structure, have avoided the condition of collapsing because the amount of deflection is too big and breaking into, have practiced thrift the cost again.
The technical scheme of the utility model is that:
two T board ribs and support reinforcing strutting arrangement between girder steel, support shaped steel, locate to consolidate on supporting shaped steel and support the reinforced packing subassembly of being connected with two T board ribs including arranging the reinforcement of supporting the girder steel upper surface, its technical essential is: the reinforcing rib plate is arranged on two sides of the web plate of the supporting steel beam and perpendicular to the web plate, the reinforcing and filling assembly comprises a wrapping channel steel, a vertical steel plate and two opposite pull bolts, the wrapping channel steel is located at the bottom of the web plate, the groove opening of the wrapping channel steel faces upwards, the vertical steel plate is fixedly connected with wing plates on two sides of the wrapping channel steel respectively, the two opposite pull bolts penetrate through the double-T plate rib and the two vertical steel plate fixedly connected with the two vertical steel plate, and a filling area is formed between the inner surfaces of the wrapping channel steel and the two vertical steel plates and.
Foretell two T board ribs and support reinforcing strutting arrangement between girder steel, it is H shaped steel to consolidate the support shaped steel, and its and the contact surface who supports the girder steel upper surface are the pterygoid lamina of consolidating the support shaped steel, and its web is level mutually with the stiffening rib board.
The reinforcing and supporting device between the double-T plate rib and the supporting steel beam is characterized in that the wing plate and the two vertical steel plates wrapping the channel steel are parallel to the double-T plate rib, and the length of the rib plate wrapping the channel steel is l1The length of the reinforcing support section steel is l2The width of the supporting steel beam is l3，l1＞l2＞l3。
In the reinforcing and supporting device between the double T-shaped plates and the supporting steel beam, the two split bolts are arranged on the same horizontal line and are positioned at the upper part of the vertical steel plate.
The utility model has the advantages that:
1. add the reinforcement and fill subassembly bottom original two T board ribs, set up stiffening rib plate inside supporting the girder steel, and support the reliable welding of shaped steel through consolidating, make whole building structure more firm, compare in the area of contact of lug connection between current support girder steel and two T board ribs, the design of this structure makes and connects the area of contact increase, has reduced the span, has increased the bearing capacity of two T boards, eliminated two T board amount of deflection and too big and the potential safety hazard that brings.
2. The reinforcing transformation construction of whole device only need use behind the two T boards of lifting such as jack, assembles the construction, can not cause destruction to the primary structure, more need not change whole, greatly reduced construction cost.
3. Pack the grout blanket in the filling area, can select for use C50 grout, compare in concrete structure, its intensity is higher, the rapid hardening, and it is more firm to make to consolidate the packing subassembly, need not frequently to consolidate the change.
