METHOD FOR STRENGTHENING CONCRETE OR TIMBER STRUCTURES USING CFRP STRIPS AND CONCRETE OR TIMBER STRUCTURES STRENGTHENED BY THIS METHOD
This method is suitable for the strengthening of concrete or timber structures (1, 4) by applying prestressed Carbon FRP or Glass FRP lamella (8). Firstly, at least one groove (22) is cut into the concrete or timber structure (1, 4) along the direction in which the concrete or timber structure (1, 4) is to be strengthened. The grooves (22) are filled with epoxy resin (9) and a layer of epoxy resin (9) is put onto the entire section to be equipped with the CRFP or GFRP lamella (8). The lamella (8) will be prestressed and anchored at both ends. U-shaped brackets (24) are then being put over the two end sections of the CFRP or GFRP lamella (8) by inserting and submerging its both U-legs (27) into holes (26) filled with resin as well. These holding brackets (24) will then tightly press onto the CFRP or GFRP lamella (8) to prevent cracking or fracture of the concrete or timber and bending away of the extremities of the CFRP or GFRP lamella.
SYSTEM FOR FILLING VOIDS IN GLUED-IN-ROD STRUCTURES
A glued-in-rod wooden structure includes a prepared hole for sealing voids which may be open to the prepared hole. In one example, the prepared hole is filled with an expanding foam which at least partially fills and seals the voids open to the prepared hole. Thereafter, the prepared hole may be enlarged by drilling to its final diameter for receiving the rod. Any voids in the enlarged hole remain sealed by the expanding foam.
Method for strengthening concrete or timber structures using CFRP strips and concrete or timber structures strengthened by this method
This method is suitable for the strengthening of concrete or timber structures by applying prestressed Carbon FRP or Glass FRP lamella. At least one groove is cut into the concrete or timber structure along the direction in which the concrete or timber structure is to be strengthened. The grooves are filled with epoxy resin and a layer of epoxy resin is put onto the entire section to be equipped with the CRFP or GFRP lamella. The lamella is prestressed and anchored at both ends. U-shaped brackets are then being put over the two end sections of the CFRP or GFRP lamella by inserting and submerging its both U-legs into holes filled with resin as well. These holding brackets are then tightly pressed onto the CFRP or GFRP lamella to prevent cracking or fracture of the concrete or timber and bending away of the extremities of the CFRP or GFRP lamella.
WOOD WITH STRENGTHENING COATING
An enhanced wood product includes a wooden board or plank having a length and at least three sides, the sides defining a polygonal cross section along the length of the wooden board or plank. A polyurethane-urea coating on at least two of the sides very substantially increases the strength of the wood product and various products made with coated wood.
Method for producing a bar element
A bar element as a construction element includes strips preferably produced from bamboo and is hollow at least in certain regions. The hollow interior is formed at least in certain sections as a hollow fillet achieved by a plastic and/or resin introduced into the bar elements, using a shaped body movable through the interior. Producing bar elements from interconnected strips ensures that although produced from a natural raw material, the bar elements have a reproducible outer cross section. Using a shaped body movable through the interior to produce the inner cross section also ensures a defined inner cross section of the bar elements, with the result that in turn connections between a plurality of bar elements that are defined by suitable connection elements can be formed. In this way, the bar elements make it possible to produce lattice works, grid constructions, frameworks or other desired structures and/or three-dimensional bodies.
Cantilevered portion of a light frame construction building using structural engineered wood rim boards
A cantilevered peripheral portion of a light frame construction building, having a peripherally bounded interior, is disclosed. The cantilevered peripheral portion involves two structural engineered wood rim boards each having cavities facing the exterior of the building and joined at their terminal ends at an angle. One of the two structural engineered wood rim boards supports a first group of studs located above, along, and supported by, an upper flange a first of the two structural engineered wood rim boards. At least one supporting wall stud is located beneath a lower flange of a second of the two structural engineered wood rim boards such that a cantilevered overhang configuration is formed between the first group of studs and the at least one supporting wall stud.
Method to prevent dry rot damage to a wood fence
A spacer apparatus and method to prevent dry rot damage to a fence is provided. The fence includes posts disposed in the ground, a horizontal support plank coupled to each pair of adjacent posts, pickets disposed on the horizontal support plank, and a pair of horizontal rails disposed on the horizontal support plank. The spacer apparatus includes a plate and a pair of end tabs coupled to the plate, each end tab coupled to a side edge of the plate and having a first width that is less than a second width of the plate along the side edge. The plate is disposed on the horizontal support plank to permit the end tabs to conform to the horizontal support plank for stability, thereby enabling the plate to support the pickets and horizontal rails above the horizontal support plank. The end tabs are then removed from the plate.

One of the two structural engineered wood rim boards supports a first group of studs located above, along, and supported by, an upper flange a first of the two structural engineered wood rim boards.

Structural engineered wood rim board system for light frame construction
A peripheral portion of a light frame construction building constructed from structural engineered wood components involves first, second and third structural engineered wood rim boards each having a cavity on an exterior-facing side and a substantially flat interior-facing side, with ends of the second and third structural engineered wood rim boards abutting each other to form a corner, and an auxiliary corner support affixed to, and within the cavities of, the second and third structural engineered wood rim boards.
