Problems solved by technology

[0003] Because the existing stirrups are all single steel bars or composite materials surrounded by workers manually, their size is difficult to grasp, and it takes a lot of manpower and time; the steel stirrups are heavy and inconvenient to operate, and It will increase the overall weight of the building and increase the cost; and because there are solder joints or openings on each single-turn stirrup, the shrinkage stress is uneven

Embodiment Construction

[0020] The present invention will be further explained below in conjunction with the accompanying drawings.

[0021] Manufacture a glass fiber spiral stirrup with a diameter of 20 mm and a weight of 570 g, wherein the glass fiber content is 427.5 g, accounting for 75% of the total weight, and the resin content is 25%, which is 142.5 g.

[0022] (1) Dipping: take 89 pieces of 4800tex pultruded glass fiber yarn, arrange the glass fiber yarn on the creel 1 according to its length direction; lead the glass fiber material yarn from the creel 1, and use pultrusion The process organizes all the fiberglass yarns into a large bundle and then impregnates them in the resin binder tank 2. The resin used is epoxy resin, and the model produced by Baling Petrochemical Co., Ltd. is 128. During deployment, the curing agent and accelerator provided by the company are used, and the consumption is respectively 5% of the total weight of epoxy resin.

[0023] If it needs to be used in flame-retard...

Abstract

The invention discloses a method for processing composite fiber material spiral stirrup. The method comprises the following steps of: gumming, premolding, semi-solidifying and drying, molding spiral stirrup, sizing and drying, and cutting and packaging. In the multiturn continuous closed-type composite material spiral stirrup of the invention, the continuous spiral composite material stirrup replaces the single-ring composite material stirrup, so that the spiral stirrup can save materials and man-hours in the same member, resists corrosion, and can also improve the bearing capacity of a girder or a column under the condition of constant section and equal spacing; the tensile strength of the composite material stirrup is three times that of steel bar; the weight is only one-fourth that of the steel bar; and the composite material stirrup has the advantages of no magnetism, water resistance, freeze resistance, strong chemical corrosive resistance and the like; and due to the adoption of a process for molding the composite fiber material spiral stirrup, the disadvantage that a conventional composite material is difficult to bend into the stirrups with different shapes after solidification and sizing is overcome, and the shape of the composite material steel bar can be changed so as to manufacture the spiral stirrup according to the requirements of people.

Description

technical field [0001] The invention relates to a molding method of a composite fiber material, in particular to a processing method of a composite fiber material spiral stirrup used on a material reinforcement frame member in the construction industry. Background technique [0002] In construction engineering, in order to avoid the shear failure of the structure under the action of external force after the completion of the structure, stirrups are usually set between the main steel bars and the surrounding concrete to fix the main composite bars or other bars. to enhance the shear strength of the structure. The existing stirrups are usually made of steel bars, and the stirrups made of steel bars need to be welded and fixed at the openings, and multiple stirrups need to be stacked continuously on each structure. Stirrups can also be made of composite materials, including sealing hoops and buckle hoops. So far, these composite material stirrups are made by hand, and they are...
