Abstract
The utility model discloses a reinforcing structure of concrete beam, the characterized by angle steel is buckled in 13 and 23 departments, and the angle steel is buckled and is located surely to go out triangular notch, and triangular notch back welding steel sheet is strengthened, and welding steel sheet welding width is 150~200mm, and steel sheet thickness is 12~14mm, the angle steel is buckled and is located to set up fastening screw, and the fastening screw diameter is 18~22mm, and the nut height is greater than 1.5 times of the screw rod diameter, the angle steel is put to two bight equipartitions below the concrete beam, welds the batten plate between two bight angle steel, and batten plate thickness is 10~12mm, and the batten plate width is 100~120mm.
Description
Technical field
This utility model is related to a kind of ruggedized construction, particularly to a kind of ruggedized construction of beams of concrete.
Background technology
Old building by long-term use after the phenomenon of depression of bearing force occurs because of a variety of causes, be mainly manifested in Old building
The beams of concrete of thing occurs depression of bearing force because of concrete carbonization, or bearing capacity occurs because of the lifting using standard can not
Reach requirement.Therefore for old building, the overall load effect of reinforcement structure, improve the mechanical property of structure.
Utility model content
This utility model is to provide a kind of ruggedized construction of beams of concrete, solves the problems, such as that beams of concrete bearing capacity is inadequate.
According to the loading characteristic of beams of concrete, concrete beam strengthening is taken as follows：Apply at the 1/3 and 2/3 of beams of concrete
Plus prestressing force upwards can alleviate the maximal bending moment of beams of concrete significantly, so angle steel bends at 1/3 and 2/3 in the present invention,
Angle steel bending place cuts out vee, and vee back side welding steel is strengthened, and welding steel weld width is 150
～200mm, steel plate thickness is 12～14mm.Angle steel bending place arranges fastening screw, a diameter of 18～22mm of fastening screw, nut
Highly it is more than 1.5 times of screw diameter.Beams of concrete following two corner uniform angle setting steel, left comer portion angle steel and right corner portion angle steel
Between weld batten plate, batten plate thickness be 10～12mm, batten plate width be 100～120mm.
Beams of concrete construction procedure is using as follows：
(1) temporary support is provided below in beams of concrete；
(2) cut the brick wall 250～300mm of supporting beams of concrete, be angle steel construction indwelling working place；
(3) inserted angle steel after beams of concrete removing surface；
(4) fastening screw is installed, prestressed stretch-draw is carried out to angle steel；
(5) welding steel and batten plate.
Present configuration performance is good, safe and reliable.
Brief description
Fig. 1 is concrete strengthening pre-structure schematic diagram, and Fig. 2 is concrete strengthening structural representation.
In each accompanying drawing：1st, angle steel, 2, fastening screw, 3, steel plate, 4, batten plate.
Specific embodiment
The present embodiment concrete beam strengthening is taken as follows：Apply prestressing force meeting upwards at the 1/3 and 2/3 of beams of concrete
Significantly alleviate the maximal bending moment of beams of concrete, so angle steel 1 bends at 1/3 and 2/3 in the present invention, angle steel 1 bending place cuts out
Vee, vee back side welding steel 3 is strengthened, and welding steel 3 weld width is 180mm, steel plate 3 thickness
For 12mm.Angle steel 1 bending place arranges fastening screw 2, a diameter of 20mm of fastening screw 2, and nut height is 40mm.Beams of concrete
Following two corner uniform angle setting steel 1, welds batten plate 4 between left comer portion angle steel 1 and right corner portion angle steel 1, batten plate 4 thickness is
10mm, batten plate 4 width is 100mm.
Claims (1)
1. a kind of ruggedized construction of beams of concrete, is characterized in that angle steel bends at 1/3 and 2/3, angle steel bending place cuts out triangle
V notch v, vee back side welding steel is strengthened, and welding steel weld width is 150～200mm, and steel plate thickness is
12～14mm；Angle steel bending place arranges fastening screw, a diameter of 18～22mm of fastening screw, and nut height is more than screw diameter
1.5 again；Beams of concrete following two corner uniform angle setting steel, between two corner angle steel weld batten plate, batten plate thickness be 10～
12mm, batten plate width is 100～120mm.
