[0004] 2) Limitations of traditional construction:
[0005] The traditional splicing of steel formwork adopts manual positioning with positioning pins. The bolts are tightened to reduce the butt joints between the steel forms. If the holes are enlarged, the formwork is prone to misalignment; on the other hand, due to the tightening of the bolts, it may cause uneven or incomplete screwing, deformation of the formwork or insufficient joints, resulting in grout leakage and poor concrete appearance quality

Embodiment Construction

[0033] The following non-limiting examples illustrate the invention.

[0034] refer to Figure 1-10 As shown, a tongue-and-groove formwork that can be spliced ​​quickly and prevents mistakes, includes a pier formwork formed by splicing a plurality of formwork panels 1, and the outer wall of the formwork panel 1 is also provided with vertical ribs 2 and horizontal ribs. Small ribs3. As in this example figure 1 As shown, four formwork panels 1 are spliced ​​into a rounded rectangular shape. The joints 4 of the template panels 1 spliced ​​in pairs are respectively provided with tenons 6 and tenon grooves 7 along the length direction, and the tenons 6 and tenon grooves 7 are matched and corresponding, and the butt joints 4 of the two spliced ​​template panels 1 The flange sides 5 at the position are also fastened by three bolts 8 arranged at the head, tail and middle in the overall length direction, such as Figure 4 , 5 As shown, the outer periphery of the pier formwork is a...

Abstract

The invention discloses a quick-splicing and slab staggering prevention tenon-and-mortise type template and belongs to the field of bridge concrete structure construction. The quick-splicing and slab staggering prevention tenon-and-mortise type template comprises a pier table template formed by a plurality of template panels by splicing, tenons and mortises are respectively arranged in the lengthwise direction of flange edges of the joint positions of the template panels spliced in pairs, the tenons correspond to the mortises in a matched manner, the flange sides at the joint positions of the template panels spliced in pairs are fastened through bolts on the upper, tail and middle portions arranged in the lengthwise direction, enclosing purlins are arranged on the periphery of the pier table template, and pull rods are arranged at the diagonal positions of the enclosing purlins. By the arrangement, in-site splicing of the steel template can be fastened and improved in precision, spliced joints are free of slab staggering, and concrete is good in appearance quality.

Description

technical field [0001] The invention belongs to the field of bridge concrete structure construction, and is especially suitable for the construction of concrete steel formwork for bridge pier columns with high requirements on appearance quality. Background technique [0002] 1) Traditional pier concrete formwork: [0003] Steel formwork is currently more and more used in the construction of concrete structures such as bridge piers, columns, beams, platforms, etc. On the one hand, the steel formwork has high rigidity, high strength, good flatness and is not easy to deform, and the angular size of concrete structures is easy to obtain. control, the smoothness of the outer surface can be guaranteed; on the other hand, the turnover rate is high, the need for external support is relatively small, and the waste can be recycled repeatedly. However, with the development of the entire bridge construction environment, the requirements for the appearance quality of concrete structures...
