Embodiment 1

[0063] A snap-fastening structure is adopted between the lock 2 and the concrete template. The lock member 2 includes a lock rod 21 inserted in the through hole 121 of the fastener 1, and a lock pin 22 provided on the lock rod 21 and buckled on the concrete form 1a. The lock pin 22 is arranged at one end of the lock rod 21, and the other end of the lock rod 21 is bent to form a pressing handle 211, which presses and abuts against the fixing base 12, and the fixing base 12 has a pressing and abutting contact with the pressing handle 211 The slope 122. In this embodiment, the amount of fastening is adjusted by correspondingly provided slope 122 and pressing handle 211, and the operation is simple and quick.

[0064] In addition, such as Figure 5 with Image 6 As shown, the use of the lock nut 3 can also achieve the effect of pressing and abutting. Such as Figure 5 As shown, the lock rod 21 is provided with an external thread, the lock nut 3 is matched with the lock member 2, an...

Embodiment 2

[0067] The lock 2 adopts a bolt structure, and one end of the lock 2 passes through such as image 3 After the through hole 121 on the fastener 1 is shown, it is screwed with the demolding nut embedded on the concrete form 1a, and the other end of the lock 2 is pressed against the concrete form 1a, thereby tightly installing the concrete form 1a On the fixed rod 3a.

[0068] As a preferred embodiment of the present invention, the present invention also includes a fastening adjustment member 4 for adjusting the amount of fastening. The tightening and adjusting member 4 includes an adjusting nut 41, an adjusting screw 42 and a lock pin 43 provided at the end of the adjusting screw 42. The end of the buckle 11 extends outward to form an adjusting seat 13, and rotating the adjusting nut 41 allows the adjusting screw 42 to pass It is movably installed on the adjusting seat 13 in a manner of extending and retracting.

[0069] In addition, the adjusting seat 13 may be provided with a not...

Embodiment 3

[0072] The two ends of the buckle 11 of the buckle 1 are fastened by a lock 2 respectively. Specifically, the end of the buckle 11 extends outward to form another fixing seat 12, the fixing seat 12 is provided with a through hole 121, and the other lock member 2 is inserted through the through hole 121. Since the two ends of the fastener 1 are respectively buckled in the same quick-connect groove 2a on the concrete form 1a, the stability of the assembled concrete form 1a can be improved while the rapid assembly is improved.

Abstract

The invention discloses a fastening device for a quickly assembled concrete formwork. The fastening device comprises a fastener clamped on a fixing rod which is used for fixedly splicing a concrete formwork, and a locking piece which penetrates through the fastener to fasten the formwork unit on the fixing rod. By the fastening device for the quickly assembled concrete formwork, the fastener is directly clamped on the fixing rod which is used for fixedly splicing the concrete formwork, and the locking piece penetrates through the fastener to fix the concrete formwork to the fixing rod. Because the fastener adopts a convenient clamping mode, assembly can be efficiently and conveniently finished; moreover, the fastening device has high universality; because the assembly pieces and the fasteners can realize good fastening connection without precision fit, good fastening connection can be ensured in case of deformation in the using process; and therefore, the fastening device is applied to various complex construction sites, is free from limitation of working conditions and has wide application prospect.

Description

Technical field [0001] The invention relates to a concrete formwork component, in particular to a fast-installed fastener device for concrete formwork. Background technique [0002] In the process of precasting concrete components, a large number of templates are used. Because different shapes of buildings use different concrete templates, most of the templates cannot be reused, causing great waste; for this reason, standardized template units are used, which can be repeated Use and can be spliced ​​into various shapes of concrete templates. However, the existing formwork units are spliced ​​piece by piece during construction and fixed with complex fasteners, which is inefficient and inconvenient to operate. [0003] In order to solve the above-mentioned problems, the applicant has applied for "a quick-installed concrete formwork unit", which has an outer surface for flat splicing, and the surface includes a molding surface and a mounting surface that are arranged oppositely, and ...
