A tie system and method for forming a wall from a hardenable building material over an existing concrete wall. In one embodiment, the tie system includes multiple wall ties configured to be directly interconnected to form a wall tie stack such that multiple wall tie stacks can be positioned over the existing concrete wall in a spaced apart, vertically extending arrangement. The multiple wall tie stacks are configured to extend substantially perpendicular between substantially parallel panel structures. The tie system may be secured with the parallel panel structures to extend vertically as forms for a concrete wall and, if desired, transversely as forms for a concrete roof structure over, for example, a roof truss system, joined together with forms for forming a concrete eave portion. In this manner, the tie system may be employed to form a concrete building structure extending as the walls and roof of the structure.

A resin impregnated overlay sheet is laid atop a wood veneer to create a concrete form. At a pre-press station, pressure is applied to a veneer assembly having an overlay sheet laid atop it. Thereafter, the pressed overlaid assembly is transferred for final hot pressing. The pre-pressing of the overlay sheet onto the wood veneer ensures the static adherence of the overlay sheet to the veneer prior to final hot pressing.

A protruding-head fastener is disclosed for joining two or more members. A protruding-head fastener includes a head that protrudes when the fastener is installed and shaped to rotationally couple with a drive tool, and a shank fixedly coupled with the protruding head and having a self-tapping threaded portion and a maximum diameter. The protruding head and the shank define a longitudinal axis through the fastener. The protruding head has a length along the longitudinal axis and a maximum width transverse to the longitudinal axis such that the length divided by the maximum width defines an aspect ratio for the protruding head that is equal to or greater than 1.0. The protruding head further has a minimum width that is greater than the maximum diameter of the shank. In many embodiments, the minimum width of the protruding head exceeds 1.2 times the maximum diameter of the shank.
摘要:
Polymer-based composite materials comprising a polymer, such as high density polyethylene, and one or more functional fillers, such as powdered metals, carbon, or ceramics, are described. The composite materials can be used for concrete forming applications. For example, the polymer-based composite materials can be formed into sheets and laminated onto various non-metal substrates, such as plywood, for use as concrete pouring forms. The polymer-based composite materials can also be used as facings and liners for metal concrete pouring forms. The forms can be used multiple times without release agents and without staining or physically damaging the cured concrete. The polymer-based composite materials can be provided with various surface textures, patterns, and designs. Methods for bonding the polymer-based composite materials to various non-metal and metal substrates are also described.

The present invention provides a building structure in which a Korean-style house and a wooden house are introduced to modern architecture, including: a framework made of reinforced concrete or concrete; and a mold for forming the framework, wherein the mold is used as a permanent mold and is a Korean-style house finishing material which is integrated with the reinforced concrete or concrete and is used as a finishing material of the interior and exterior of a building, thereby preventing indoor environmental pollution which may occur during the adhesion of finishing interior materials in a conventional construction method, and maintaining indoor humidity and improving an indoor environment since the structure is finished with natural materials such as wood and yellow loess. In addition, composite structures are integrated without damaging a reinforced concrete or concrete structure, thereby ensuring structural stability and enabling the combination of a high-rise building and a Korean-style house structure.
摘要:
A composite structure formed of a concrete slab and an integrated formwork element, wherein: the formwork element includes a side wall, against which concrete is poured to define a side of the slab, and a lateral flange that covers a top or bottom peripheral edge of the slab, wherein: the lateral flange has a grip that extends into a main body of the slab in a vertical direction, to form a space between the grip and the side wall, which is substantially filled with concrete such that the concrete locks into the space and structurally integrates the element with the concrete slab: and wherein: the lateral flange has a groove formed in an external face of the flange, opposite the slab, to serve as an anchor site for a load transfer member attached externally of the composite structure by being fitted to the formwork element.
摘要:
The invention comprises a concrete form. The concrete form comprises a first panel having a first primary surface for contacting plastic concrete and a second primary surface opposite the first surface; and a second panel having a first primary surface and a second primary surface opposite the first surface, the second panel being attached to the first panel so that the first primary surface of the second panel is adjacent the second primary surface of the first panel. The concrete form also comprises a layer of radiant heat reflective material and a layer of insulating material disposed between and covering the second primary surface of the first panel and first primary surface of the second panel. A method of using the concrete form is also disclosed.
摘要:
A system, which can make possible to record the management data of construction materials without separating said data from the construction materials themselves and to check those data at any time, is provided.For achieving the foresaid object, a system is constituted such that it comprising an IC tag 3 of the non-contacting type to be attached to a construction material 1, 4 and a reader-writer 10 for writing data to and read data from said IC tag 3, wherein at least the management data of said construction material is written to or red from said IC tag 3.
