LPEC beam

Abstract

The utility model discloses an LPEC beam which comprises a steel beam body, a plurality of corner connectors are arranged on the inner top face and the inner bottom face of the steel beam body in a mirroring mode, and the other end of each corner connector is provided with a corresponding coal gangue lightweight aggregate fireproof plate through a plurality of self-tapping screws. The coal gangue lightweight aggregate fireproof plates are tightly attached to the left end face and the right end face of the steel beam body respectively, and fireproof coating is arranged on the lower surface of the steel beam body. The utility model solves the problems that the fireproof cost of the LPEC beam is increased and the large-area fireproof anticorrosive coating is difficult to maintain because the traditional steel beam with the fireproof plate adopts the large-area fireproof anticorrosive coating.

Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to an LPEC beam. Background Technology

[0002] Lightweight partially encased concrete-steel beams (LPEC beams) are steel-concrete composite beams encased in lightweight aggregate ceramsite concrete slabs. They can be used for both main and secondary beams. To delay the heating of steel, maintain its load-bearing capacity in a fire, buy time for life safety and fire rescue, and avoid catastrophic consequences of structural collapse, the fire-resistant function of LPEC beams is particularly important.

[0003] Traditional steel beams with fireproof panels use large areas of fireproof and anti-corrosion coatings, which increases the cost of fireproofing LPEC beams, and large areas of fireproof and anti-corrosion coatings are difficult to maintain. Utility Model Content

[0004] The purpose of this invention is to overcome the existing defects and provide an LPEC beam that can use coal gangue lightweight aggregate fireproof board to replace most of the fireproof and anti-corrosion coatings, reduce costs, and facilitate subsequent maintenance.

[0005] The technical solution to achieve the above objective is: an LPEC beam, including a steel beam body, wherein multiple corner brackets are mirror-imagely provided on the inner top and inner bottom surfaces of the steel beam body, and a corresponding coal gangue lightweight aggregate fireproof plate is installed on the other end of each corner bracket by multiple self-tapping screws, and each coal gangue lightweight aggregate fireproof plate is respectively tightly attached to the left and right end faces of the steel beam body, and the lower surface of the steel beam body is provided with fireproof coating.

[0006] Preferably, the upper surface of the steel beam body is uniformly provided with a plurality of studs.

[0007] Preferably, beam-column connection nodes are provided at both the front and rear ends of the steel beam body.

[0008] The beneficial effects of this utility model are as follows: multiple corner brackets are mirror-image arranged on the inner top and inner bottom surfaces of the steel beam body. The other end of each corner bracket is fitted with a corresponding coal gangue lightweight aggregate fireproof plate through multiple self-tapping screws. Each coal gangue lightweight aggregate fireproof plate is tightly attached to the left and right end faces of the steel beam body. Multiple coal gangue lightweight aggregate fireproof plates are wrapped around the left and right end faces of the steel beam body by means of threaded connection. This method can replace large-area fireproof and anti-corrosion coating, reduce the cost of this structure, and facilitate subsequent maintenance. Attached Figure Description

[0013] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 1-3 As shown, an LPEC beam includes a steel beam body 1. Multiple corner brackets 2 are mirror-imagely arranged on the inner top and bottom surfaces of the steel beam body 1. The other end of each corner bracket 2 is fitted with a corresponding coal gangue lightweight aggregate fireproof plate 3 by multiple self-tapping screws. Each coal gangue lightweight aggregate fireproof plate 3 is tightly attached to the left and right end faces of the steel beam body 1. Multiple coal gangue lightweight aggregate fireproof plates 3 are wrapped around the left and right end faces of the steel beam body 1 by threaded connection. This method can replace large-area fireproof and anti-corrosion coating, reduce the cost of this structure, and facilitate subsequent maintenance. The lower surface of the steel beam body 1 is provided with fireproof coating 4.

[0016] Specifically, the upper surface of the steel beam body 1 is uniformly provided with multiple studs 5; the front and rear ends of the steel beam body 1 are provided with beam-column connection nodes 6.
