Pin fastening component

Abstract

The invention relates to a pin fastening component. The pin fastening component comprises a pin and a pin sheet, wherein the inner end part of the pin is fixedly arranged on a clamping plate; one sideof the pin sheet is provided with a clamping groove for accommodating the pin; the outer edge of the pin is symmetrically provided with a first clamping inclined plane along the axial direction; theinclination angle between the first clamping inclined plane and the axis of the pin is beta; the first clamping inclined plane is in contact with a second clamping inclined plane arranged on the outeredge of the pin; the inclination angle of the second clamping inclined plane is alpha; two side edges of one end surface of the clamping groove of the pin sheet are provided with a pin sheet inclinedplane matched with the second clamping inclined planes; and the inclination angle of the pin sheet inclined plane is gamma. According to the pin fastening component, two clamping inclined planes arearranged on the outer edge of the pin, and are matched with the clamping groove of the pin sheet and the pin sheet inclined plane, so that the deeper the pin sheet is inserted, the closer the pin sheet is matched with a clamping piece. The pin fastening component adopts a double progressive clamping mode, namely, on the one hand the pin and the pin sheet are matched and clamped, and on the other hand, a screw rod and a threaded sleeve are matched and clamped, so that the two templates are firmly jointed and clamped.

Description

technical field [0001] The invention belongs to the technical field of building construction and relates to a formwork, in particular to a pin fastening component. Background technique [0002] Building formwork is composed of panels and support systems. The quality of formwork assembly is related to the quality of concrete engineering. The key lies in accurate size, firm assembly, tight joints, and convenient disassembly and assembly. At present, pins and pin sheets are usually used as connecting fasteners of the formwork. [0003] After searching, a patent document similar to this patent application was found, the name is: a template connector, and the application publication number is: CN106121229A. The published content of this patent application is: including a pin, a pin piece and a connecting rope connecting the pin and the pin piece; The body is provided with a pin hole, and one side of the nail cap has a protrusion. [0004] By comparison, it is found that the ab...

Problems solved by technology

[0005] 1. The template is easy to deform and expand the mold

[0006] The pin is inserted into the hole of the pin to achieve the purpose of connecting two templates. This connection structure is basically "point" contact, the clamping area is small, the mold is easy to expand when dusting, and the service life is low; the template is easy to deform, directly Affects the pouring quality of concrete walls

[0007] 2. Difficult to install

[0008] The pins and pins are plugged in. Due to the unequal gap between the two templates, it is difficult for the pins to be inserted into the holes of the pins.

[0009] 3. Pins and pins are easy to loosen

[0010] Due to the use of vibrating rods during the grouting process, when the pins are vibrated and the two sides of the pins are inclined structures, the pins are easy to move and fall out. At this time, the pins and pins basically do not play the role of clamping , prone to bulge and dust

[0011] 4. The connection between the pin and the pin is not tight and easy to loosen

[0012] The pin is basically very easy to use for the first time. When the pin is inserted into the pin hole and hammered vigorously, there are often "steps" on the edge where the pin contacts the pin. When the pin is used for the second time, the pin will be stuck on this The "step" position, causing the problem of pin not tight
