Abstract
Description
Technical Field
[0001] The utility model belongs to the field of construction engineering tools, and in particular relates to a tension bolt and a concrete wall template. Background Art
[0002] Concrete walls are generally vertical slab structures with a thickness of 30 to 50 cm. Insufficient early maintenance will cause water loss on the surface of the structure or too fast a cooling rate, which will have an adverse effect on the concrete structure. In concrete construction practice, construction units are concerned about the turnover rate of the formwork, and rarely consider the impact of premature removal of thin plates on concrete projects. The formwork is often removed 1 to 2 days after concrete pouring. Since the wall is a vertical structure, the surface cannot store water, and it is difficult to ensure the quality of maintenance with conventional spray maintenance. On the one hand, it causes the surface of the concrete wall to lose water too quickly. On the other hand, premature formwork removal and insufficient maintenance cause the concrete to cool down faster, resulting in cracks in the concrete structure. Plastering the cracked concrete wall will cause uneven wall plastering. In addition, rust will appear at the cracked concrete location and exposed steel bar location during the later maintenance process. Utility Model Content
[0003] The utility model aims to provide a tension bolt and a concrete wall formwork, which are applied in a primary structural wall formwork process to avoid the rust problem of the wall and improve the problem of uneven wall plastering.

[0005] The tension bolt comprises: a fastener, a nut, a reserved plate, and a screw rod. A fastener through hole is arranged in the middle of the fastener, a reserved plate is arranged with a reserved plate through hole, and the screw rod is passed through the fastener through hole and the reserved plate through hole; two nuts are respectively connected to the two ends of the screw rod, and the reserved plate is located on the inner side of the fastener; the fastener is arranged with an arc plate.
[0006] Furthermore, the fastener is provided with two arc-shaped plates, and the two arc-shaped plates are located on both sides of the fastener through hole.
[0007] Furthermore, the reserved plate is 100mm*100mm square.
[0008] The concrete wall formwork includes: tension bolts, formwork, steel pipes, and wooden squares; a plurality of formworks form a box structure, the wooden squares are located outside the formworks, the steel pipes are located outside the wooden squares, the tension bolts are passed through two opposite formworks, the fasteners are pressed on the outside of the steel pipes, and the reserved plates are located inside the formworks.
[0009] Preferably, the steel pipes and wooden squares are placed crosswise and perpendicular to each other.
[0010] Compared with the prior art, the utility model has the following advantages:
[0011] The utility model is applied in a process of supporting formwork for a structural wall, thereby avoiding the rusting problem caused by improper treatment of the tension bolts, and can also effectively improve the problem of uneven wall plastering. BRIEF DESCRIPTION OF THE DRAWINGS
