The invention provides a building with precast reinforced concrete supports. The building is composed of the precast reinforced concrete convex supports, precast column frames, precast convex main beams, cavity floor components and connecting shallow seams among the cavity floor components. The building is characterized in that the precast reinforced concrete convex supports are each in a rhombicshape; rhombic convex support diagonal lines are constituent parts of the main beams; reserved column holes are formed in the centers of the convex supports, and longitudinal main beam reinforcing bars and transverse main beam reinforcing bars in the reserved column holes are crossed and have no reinforcing bar joint; the precast column frames are thin-wall frames, and steel wire nets are arrangedin the thin-wall frames; the cavity floor components are each shaped like a hexagon; each hexagonal cavity floor component is provided with two right-angle edges; longitudinal rib grooves and shallowconnecting seams are formed among the cavity floor components; the two ends of each precast main beam are provided with slopes or vertical grooved slopes; vertical bolt holes are reserved in the twoends of the main beams; concave grooves are reserved in the bottom surface of the two ends of the main beams; and steel plate connecting parts are assembled in the concave grooves.

A joint structure for a floorboard, including: at least one first beveled tenon, the first beveled tenon including a tenon face facing upwards; a first beveled mortise, the first beveled mortise including a mortise face facing upwards; at least one second beveled tenon, the second beveled tenon including a tenon face facing downwards; and a second beveled mortise, the second beveled mortise including a mortise face facing downwards. The first beveled tenon is disposed in parallel to a surface of the floorboard at a right edge approximately half a height of the floorboard; the first beveled mortise is disposed at an inner side of the first beveled tenon. The second beveled tenon is disposed at a left edge approximately half the height of the floorboard. The second beveled mortise is disposed at an inner side of the second beveled tenon.

An apex rhombus is delimited over the center point of a square, which is delimited by plotting four nadir rhombuses on the same plane, and each of the nadir rhombuses and the apex rhombus are jointed to form a group of pyramidal surfaces equipped with four planar slopes having substantially the same height in a pyramidal form. Two pyramidal surface slabs are assembled, each composed of pyramidal surfaces around one pyramidal surface, each sharing one nadir rhombus, adjacent each other, and arranged in a grid pattern at an equal pitch in plural directions. The pyramidal surfaces arranged in a grid pattern are each displaced by one-half pitch in a specific direction, such that the apex rhombus of one of the pyramidal surface comes in contact with the nadir rhombus of the other pyramidal surface, whereby the two pyramidal surfaces are placed one on the other.

A rapid nail-free combined type house comprises a framework part, wall surface and roof which are adhered on the framework, wherein the wall surface and the roof are respectively assembled through inserting composition boards together, wherein an inner inclined surface bayonet is arranged on one side of the composition boards, a clipping groove is additionally arranged in the bayonet, an outer inclined surface clipping head is arranged on the other side of the composition boards, a clipping arm which is extended outwards is additionally arranged on the top of the clipping head, wherein the clipping head is inserted in the bayonet, and the composition boards are connected through the bayonet and the clipping head which are on the side. The composition boards have novel structure, rapid assembly, and are environmental friendly and can not be opened by pulling on the connecting portion, and the composition boards have the effects of preventing from earthquake and flood disaster and also have the characteristics of flame-proof, acoustic insulation, thermal insulation and the like.

The device to hang an architectural panel on a wall preferably comprises a support structure having first and second surfaces and a circumferential surface therebetween, a hole between the first and second surfaces, and a screw having a head, shaft and plurality of threads about the shaft. The screw is located in the hole and connected to the support structure such that the head is at or below the first surface of the support structure and the shaft is perpendicular thereto. The device can be driven into a wall and will support an architectural panel locatable thereon. Specifically, a panel clip, attached to the back of the architectural panel, can be placed on the support structure and the device will support the panel placed thereon. The circumferential surface of the support structure preferably includes a bevel to facilitate the placement of the panel clip onto the support structure.

A precast concrete meter pit consisting of an elongated hollow pipe having a beveled support ledge at one end and notches at the opposite end is fabricated by utilizing a slip form packerhead apparatus in which the beveled support ledge is formed by a radially inwardly inclined trowel edge bearing against a pallet member which is caused to vibrate when concrete is injected into the slip form apparatus.

The present invention is building decoration board locking structure for connecting two building decoration boards. Each building decoration board has one hooked block formed in the upper part of one side and one notch in the lower part of the opposite side. The hooked block includes one connecting part and one clamping tenon extending perpendicularly from the end of the connecting part for being held with the clamping tenon of the other building decoration board, and the clamping tenon has one inclined plane and one hook. The notch has one inclined plane and slot for connection with the clamping tenon. The present invention has simple structure, easy assembling and great connecting force for connecting two building decoration boards closely. The present invention may be used widely in floor board, wall board and other building decoration boards.

The invention discloses a multi-ridge diamond composite sheet. The multi-ridge diamond composite sheet comprises a cemented carbide matrix and a diamond composite layer. The multi-ridge diamond composite sheet is characterized in that two or more protruding ridges forming a certain included angle are arranged on the end face of the diamond composite layer, and the contracting ends of all the protruding ridges extend to interest at the edge of the diamond composite layer. According to the multi-ridge diamond composite sheet, the multiple protruding ridges forming the certain angle are arrangedto serve as cutting surface sets to simultaneously cut a stratum; the stratum is pre-crushed firstly through the protruding ridges forming the certain angle, sharp surfaces (the contracting ends of the protruding ridges) are inserted into the stratum firstly, a crushed pit is further enlarged in the direction of the ridges, and then the stratum is further extruded and crushed through the bevels ofthe two sides of the set of ridge surfaces, so that the cutting surfaces of the ridges have the high ploughing effect, the crushing drilling performance of the composite sheet is improved, the drilling cutting resistance is decreased, and thus the mechanical drilling speed of a diamond drill bit is increased.
