Description
Technical Field
The utility model relates to a secondary joist fixture to and clear water concrete structure plank sheathing system who uses this secondary joist fixture belongs to clear water concrete structure template technical field.
Background
The bare concrete structure template system is widely applied to the construction industry nowadays, and is particularly common in large and medium-sized public buildings. The existing clear water concrete structure template system mainly has the following four forms:
firstly, the template 71 is made of high-quality multilayer boards, the secondary keel 73 is made of wood, and the main keel 74 is made of channel steel or square steel pipes. As shown in fig. 1, the cross runners 73 are fixed to the formwork 71 with screws 72. The formwork system has the advantage that the formwork 71 and the secondary joist 73 are convenient to fix. However, since the screws 72 are inserted from the inside to the outside of the form 71 during construction, hammer marks are left on the inner surface of the form 71, which largely affect the quality of concrete, and even if the nail holes of the screws 72 are repaired with putty and polished flat, repair marks are still left on the concrete surface, which affects the appearance. In addition, the construction speed of the template system is low, time and labor are wasted, workers are required to have high responsibility, and the quality is difficult to control.
Secondly, the template 81 is made of high-quality multi-layer plates, the secondary keel 83 is made of square steel tubes, and the main keel 84 is made of channel steel or square steel tubes. As shown in fig. 2, the cross runners 83 are secured to the outside of the form 81 by L-shaped corner clips 82. The formwork system has the advantages of safety and reliability, no damage to the inner side surface of the formwork 81 facing the concrete, and no need of repairing. However, the formwork system needs to adopt a large amount of steel, needs to invest a large amount of manpower and mechanical equipment for transportation, and is low in implementation efficiency, long in construction time and high in cost.
And thirdly, the template 91 is made of high-quality multi-layer plates, the secondary keel 93 is made of wood, and the main keel 94 is made of channel steel or square steel tubes. As shown in fig. 3, the cross runners 93 are fixed to the outer side surfaces of the formworks 91 by screws through long steel members 92 in the shape of a letter "ji". The advantages and disadvantages of this template system are the same as those of the second template system.
And fourthly, the template is made of steel plates, the main keel and the secondary keel are made of steel sections such as channel steel or I-steel, and an all-steel large template system is constructed.
