A construction method for a radiation-proof concrete hole reserved split bolt includes: 1) mounting a hole reserved sleeve; 2) mounting an inclined recoverable split bolt; 3) mounting an inclined split bolt; 4) fixing the inclined recoverable split bolt and an inclined split bolt main body; 5) pouring concrete, and dismantling related components; 6) plugging the inclined split bolt main body; and 7) plugging the hole reserved sleeve. According to the construction method, the hole reserved sleeve is obliquely arranged, the inner side of the hole reserved sleeve is sprayed with a radiation-proof coating with the functions of reducing radiation ray reflection and absorbing certain radiation rays, and in addition, after the construction of a pipeline or a line in the hole reserved sleeve is finished, the openings at both ends of the hole reserved sleeve are plugged with a radiation-proof mortar incorporated with a micro-expanding agent and a waterproof agent.

A tie nut of a formwork tie for connecting two formwork elements is secured on a tie rod to prevent inadvertent rotation by way of a form fit coupling that can be axially made to engage therewith.

The invention comprises a product. The product comprises a first removable concrete form having a concrete forming face and a first insulating panel insert having a first primary surface and an opposite second primary surface, wherein the second primary surface of the first insulating panel insert contacts the concrete forming face of the first removable concrete form. The product also comprises an elongate anchor member having an enlarged portion and an elongate portion, the elongate portion having a first end and an opposite second end, wherein the enlarged portion is disposed adjacent the first end and contacts the second primary surface of the first insulating panel insert and wherein the elongate portion extends through the first insulating panel insert and extends outwardly from the first primary surface of the first insulating panel insert. A method of using a removable insulated concrete form system is also disclosed.

Various implementations described herein are directed to a formwork system. In one implementation, the formwork system includes aluminum extrusions and aluminum castings. The aluminum castings and the aluminum extrusions can be assembled by being pressed and riveted together.

The invention relates to a frame formwork element (1) with a frame (2) and a formwork shell (3) which can be attached to the frame (2). The frame (2) has at least two frame longitudinal parts (4) and at least two frame transverse parts (5). At least one transverse bracing (6) is fixed between the frame longitudinal parts (4), said transverse bracing having two transverse braces (7) which run parallel to each other in a mutually spaced manner and between which a through-gap (8) is formed for passing through anchor rods (9). At least one guide device (10) for forming an anchor point can be inserted into the through-gap (8). The guide device (10) has an anchor hole (11) for passing through one of the anchor rods (9) and a securing region (12) for securing the guide device (10) to the transverse bracing (6). In order to pass through the anchor rod (9), the guide device (10) has a conical guide part (13) which is flush with the anchor hole (11).
