Box type steel column full-assembly type modular plate type composite fireproof structure

Technical Field

The utility model relates to a fire prevention mounting structure of steel construction cylinder, specifically speaking are board-like compound fire resistive construction of box steel column full assembled modularization.

Background

Compared with other structures, the steel structure has the advantages of high strength, light structural weight, uniform material quality, convenience for industrial production and short construction period, covers all the fields of structural engineering application, and is successfully applied to many super high-rise buildings and large-span bridges. However, the fireproof performance of the steel structure is poor, according to the design rule, when the temperature of the steel surface exceeds 150 ℃, a heat insulation layer is required to be protected, and for the structure with the fireproof requirement, heat insulation protection measures are required to be taken.

The existing steel structure fire protection measures have a plurality of problems, for example, the method for installing concrete or building blocks outside occupies large space and is troublesome in construction operation; the fireproof coating has large smell during construction, the coating is easy to age, and the working performance can be lost if the coating is in a moisture absorption and wetting state; for some coatings which are not affected by humidity, fine fiber dust is easy to disperse during construction, certain problems are brought to the protection of the environment and personnel, and in addition, the surface is loose and is only suitable for completely closed hidden engineering; the wrapping of the flexible felt-like heat insulating material has low cost, simple and convenient construction and good heat insulating property, but the heat insulating property is obviously reduced due to mechanical damage and water humidity.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a board-like compound fire resistive construction of box steel column full assembled modularization to solve the inconvenient problem that has mechanical injury of steel construction flame retardant coating construction operation of present steel construction building.

The utility model discloses a realize like this: the utility model provides a side direction gomphosis formula connecting piece for steel construction beam column connects, includes the flexible insulating layer of parcel around the cylinder surface of box steel column, sets up the stereoplasm backplate that is used for sheltering from flexible insulating layer around the cylinder surface and is located the corner connecting piece of corner with fixed connection stereoplasm backplate.

The hard guard plate is a rectangular heat insulation plate, and inner tongue-and-groove openings are formed in two sides of the hard guard plate.

The corner connecting piece is a rod body consisting of two right-angle edges, and the two right-angle edges are respectively provided with an outer rabbet matched with the inner rabbet on the hard guard plate.

Furthermore, the upper edge and the lower edge of the hard guard plate are respectively provided with a butt joint tongue-and-groove matched up and down.

Furthermore, the corner connecting piece is fixed between the bottom structural piece and the top structural piece at each corner of the periphery of the box-type steel column through the L-shaped corner plate. The tip of angle connecting piece passes through L type scute to be fixed on building structure's level is to the component, has effectively avoided in the use the outside load effect down the slip of stereoplasm backplate with rock, stability reinforcing.

Furthermore, notches are formed in the outer rabbet and the butt joint rabbet of the hard guard plates, two opposite notches at the butt joint position of the two hard guard plates form a groove, and waterproof sealing materials are filled in the groove.

The utility model discloses with flexible insulating layer cladding box steel column, set up a root angle connecting piece respectively in the four corners of box steel column, attach the stereoplasm backplate in the outside of flexible insulating layer again, the both sides of stereoplasm backplate are fixed respectively on the angle connecting piece, have formed the compound fire prevention protection structure of full assembled modularization from this. The hard guard plates are connected and fixed on the corner connecting pieces, all the protective structures are not connected with the column body of the internal box-type steel column, and the problem that the metal keel damages the section of the column body can be fundamentally solved. The hard protective plate and the angle connecting piece form a hard fireproof module of the box-type steel column, the specification standards are consistent, standardized production is facilitated, building modularization is facilitated, and an assembly type operation mode is facilitated. The corner connecting piece is a strip object with standard specification, and the hard protective plate is a flat object with standard specification, so that the corner connecting piece has the characteristics of convenience in loading and unloading, no space occupation and convenience in transportation.

The utility model discloses novel structure, the cooperation is succinct, and the outside insulating layer that is formed by the stereoplasm backplate can play fine guard action to inside flexible insulating layer, makes it avoid mechanical injury. In addition, the utility model discloses still can form good seal to solve inside flexible insulating layer and reduce the problem of heat-proof quality because of receiving water and humidity to influence. The utility model discloses a surface is neat level and smooth, construction easy operation, and the installation is swiftly convenient.

Detailed Description

As shown in fig. 1, 2 and 3, the present invention includes a flexible thermal insulation layer 10, a hard guard plate 40, and corner connectors 30. The flexible heat insulation layer 10 is wrapped around the surface of the column body 70 of the box-type steel column and is bundled and fixed through the binding belts 20 arranged at intervals. Four corners of the box-type steel column are fixedly connected with a corner connecting piece 30 by L-shaped angle plates 50 respectively. The corner connector 30 is fixed between the floor and the roof at the peripheral corners of the box-type steel column through the L-shaped angle plate 50. The corner connector 30 is a rod-shaped section bar formed by two right-angle edges, and the two right-angle edges are respectively provided with an outer tongue and groove. The hard guard plate 40 is a rectangular heat insulation plate, and inner tongues and grooves matched with the outer tongues and grooves on the corner connecting pieces 30 are arranged on two sides of the hard guard plate 40. The hard guard plate 40 is attached to the surface of the flexible heat insulation layer on one side of the column 70, the inner rabbet of the hard guard plate 40 is matched with the outer rabbet on the corner connecting piece 30, and the hard guard plate 40 can be fixed on the corner connecting piece 30 by using the screw 60.

For the thinner hard guard plate 40, the inner tongue-and-groove may not be provided on both sides thereof, and accordingly, the outer tongue-and-groove on the corner connector 30 may be made into a tongue-and-groove having a thickness identical to that of the hard guard plate, so that the hard guard plate 40 may be directly fixed on the outer tongue-and-groove of the corner connector 30.

All seams of the hard guard plates 40 can be provided with notches, two opposite notches at the joint of the two hard guard plates form a groove, and the groove is filled with waterproof sealing materials, so that the air tightness of the closed space of the hard guard plates can be realized.
