Embodiment 1

[0040] A half-pack GFRP shear connector such as figure 1 and figure 2 As shown, the half-pack GFRP shear connector is a new shear nail 1 formed by structural improvement on the basis of traditional shear force, which includes a shear nail body 11 and a GFRP inclusion 12 . The shear nail body 11 is provided with a nail head 111 and a mandrel 112 connected to the lower end of the nail head 111 . The GFRP package 12 is composed of a cross cap portion 121 and an abutting portion 122 that is fixedly connected to the lower surface of the cross cap portion 121 and integrally formed with the cross cap portion 121 . The GFRP inclusion 12 is provided with a cavity on the inner surface of the cross cap portion 121 toward the lower surface of the abutment portion 122 that matches the nail head 111 and the mandrel 112 of the shear nail body, and the GFRP inclusion 12 is wrapped around the shear nail body through the cavity. 11 , the total length of the GFRP inclusion 12 is the same as t...

Embodiment 2

[0043] A structural wall panel such as image 3 and Figure 4As shown, the structural wall panel is provided with an outer panel 2, an inner panel 4, a shear nail 1, a FRP edge panel 5 and a thermal insulation sandwiched between the outer panel 2 and the inner panel 4. Layer 3. The FRP edge sealing plate 5 consists of a vertical support portion 52, a horizontal bottom portion 53 provided at the bottom end of the support portion 52 and extending to both sides, and a horizontal top portion provided at the top of the vertical support portion 52 and extending to one side. 51 composition. The thermal insulation layer 3 is composed of a light steel keel frame 31 composed of U-shaped steel 311 and a rock wool 32 thermal insulation material filled in the keel frame 31 . The upper and lower surfaces of the thermal insulation material and the FRP edge banding board 5 abut against the inner surfaces of the outer wall panel 2 and the inner page wall panel 4 correspondingly, and the low...

Embodiment 3

[0046] like image 3 The processing method of the structural wall panel shown, the processing method comprises the following processing steps:

[0047] Step 1: Prepare materials (shear nail 1, FRP edge plate 5, U-shaped steel, etc.), tools, etc.; according to the keel size on the wall panel drawing, cut the U-shaped steel 311, and then according to the shear nail 1 layout diagram in The upper flange of U-shaped steel 311 is punched, and the punching position must be close to the U-shaped steel web;

[0048] Step 2: Assemble the finished keel into a frame with rivets, and then weld the connection points between the keels; according to the size and bearing requirements of the designed structural wall panel, if necessary, increase the horizontal or / and vertical U in the keel frame 31 Section steel is welded and connected to the keel frame 31 to enhance the overall strength; the upper and lower flanges of the added U-shaped steel are aligned with the upper and lower flanges of th...

Abstract

The invention discloses a half-wrapped GFRP shear connector, a structural wallboard and a wallboard processing method.The half-wrapped GFRP shear connector is formed by wrapping the upper end of a traditional shear nail with a GFRP wrapping body made of GFRP materials, the GFRP wrapping body is provided with a cross-shaped cap part and an abutting part, the abutting part is fixedly connected to the lower surface of the cross-shaped cap part and integrally formed with the cross-shaped cap part, and the cross-shaped cap part and the GFRP wrapping body are integrally formed. The nail head part is completely positioned in the cross-shaped cap part; the cross-shaped cap portion is of a big-end-up structure, and an abutting face exceeding the lower end face of the cross-shaped cap portion is formed at the position, connected with the cross-shaped cap portion, of the abutting portion. The structural wallboard is a light steel keel wallboard, and U-shaped steel of a light steel keel and an outer wallboard of the structural wallboard adopt half-wrapped GFRP shear connectors. The half-wrapped GFRP shear-resistant connecting piece is used for effectively blocking a heat exchange path inside and outside a wallboard when an outer wallboard on the wallboard is connected with a keel, and the heat preservation performance of the wallboard and the anti-pulling bearing capacity of the wallboard are improved.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a half-pack GFRP shear-resisting connector-shear nail and a processing method of a structural wall panel and a wall panel. Background technique [0002] Shear-resisting connector Shear nails are widely used in the connection between keel and outer leaf concrete slab in light steel keel wall panels, but traditional shear nails consist of a stubby head and a slender core, mostly stainless steel. , The thermal conductivity is large, and the shear nails are connected to the light steel keel, so that there are heat exchange channels in the inner and outer leaves of the light steel keel wallboard, thereby reducing the thermal insulation performance of the overall wallboard. In addition, when the traditional stainless steel shear nail is connected to the keel and the outer panel, the nail head is embedded in the outer panel, and the bottom of the nail core is welded to ...
