Embodiment Construction

[0026] The present invention will be further described in detail below in combination with specific implementation methods and accompanying drawings.

[0027] The first step is to install the vertical support of the equipment on the concrete shear member, and drive the expansion bolts of the vertical support into the concrete at the bottom of both sides of the cast-in-place concrete beam, and fix the vertical support.

[0028] The second step is to install the bottom bracket of the device and connect the device bracket into a whole.

[0029] The third step is to weld the fixing nut and the vertical support, pass the shaft head of the roller bearing through the fixing nut, and then connect with the handle through bolts. Place the plate fixing device with rolling pulleys on the bottom bracket of the equipment, connect the roller bearings with the sleeve, and insert the other end of the screw into the bolt hole of the propulsion platform, and connect with the fixing bolts. There...

Abstract

The invention discloses a device for enabling a concrete member to resist shear and be reinforced by bonding plates and a construction method. The device comprises vertical supports, a bottom support, pushing devices and plate fixing devices. The tops of the vertical supports are fixed to concrete slabs on the two sides of a beam through fixing bolts; the bottom support is fixedly connected with the vertical supports through high-strength bolts and long circular screw holes of the vertical supports; a screw rod of each pushing device penetrates through a welded nut arranged on the middle of the corresponding vertical support and a screw hole formed in the middle of the corresponding vertical support; the plate fixing devices are connected with the screw rods of the pushing devices through screw holes and nuts; reinforced plates coated with a binding material are fixed to the plate fixing devices. By means of the device, the plates can be accurately bonded to a specified position, and meanwhile, the ends of the plates are anchored through U-shaped hoops, so that the end stripping phenomenon is avoided. By means of the device, the bonding quality can be ensured, and the construction efficiency can also be improved.

Description

technical field [0001] The invention relates to the field of building structure construction methods, in particular to equipment and a construction method for shear-resisting and strengthening concrete components with sticky plates. Background technique [0002] When bonding steel and composite material plates to strengthen reinforced concrete shear members, in order to obtain a better reinforcement effect, on the one hand, it is required that the reinforced plates have higher flatness after being bonded; on the other hand, it is necessary to avoid strengthening the plates during construction. For the composite plate composed of high-strength mortar layer and fiber material, during the construction process, because the stiffness of the composite plate is relatively small, and the length is long (same as the length of the beam), the composite reinforcement material is the same as the beam. Large deformation or even breakage may occur during horizontal placement, erection and ...
