Description

A cold-formed thin-walled light-steel composite wall piece with a keyed connection structure

technical field

The invention relates to the field of prefabricated walls, in particular to a cold-formed thin-walled light-steel composite wall sheet with a keyed connection structure.

Background technique

The main structure of the wall of the cold-formed thin-walled light steel structure is a steel skeleton formed by riveting a plurality of cold-formed thin-walled C-shaped steel members. During construction, the steel frame is first installed in place, and then the adjacent frames are connected with self-tapping screws or rivets to form a longer wall frame. Then fill the skeleton with rock wool or foam for thermal insulation. Then install OSB boards on both sides of the skeleton, and lay moisture-proof breathing paper on the outside, and finally install wooden keel strips and external wall panels. Except for the production and assembly of the steel frame, which is completed in the production workshop, the rest of the assembly work is often completed on the construction site. The disadvantages are: the assembly level of wall assembly is not achieved, the construction efficiency is low, and the number of labor and equipment is still large.

The insulation layers such as rock wool, OSB board, breathing paper and external wall panels are assembled in the workshop into short integral composite wall pieces, and then each integral composite wall piece is transported to the installation site for assembly to form a longer wall. It can greatly improve production efficiency, reduce the occupation of labor and equipment, and realize the important original intention of prefabricated buildings. However, since the inner and outer sides of the steel frame of the completed wall piece are covered and blocked by the assembled component elements, such as OSB board, breathing paper and external wall panel, etc., on the premise of not destroying the assembled elements, directly connect the composite wall. It is impossible to use rivets or self-tapping screws to connect the connecting steel frames of the sheets to form a wall.

Therefore, a cold-formed thin-walled light-steel composite wall sheet with a snap-key connection structure is invented, which is simple in structure, reasonable in design, convenient for on-site installation, firm and reliable in connection, easy in production and processing, and low in cost.

SUMMARY OF THE INVENTION

In view of the deficiencies of the prior art, the present invention provides a cold-formed thin-walled light-steel composite wall sheet with a snap-key connection structure, which is simple in structure, reasonable in design, convenient for on-site installation, firm and reliable in connection, easy in production and processing, and low in cost. .

The technical scheme of the present invention is realized as follows: a cold-formed thin-walled light-steel composite wall piece with a key-type connection structure includes a wall piece 1 and a wall piece 2 that are connected to each other, and the wall piece 1 and the wall piece 2 are respectively arranged in the wall piece 1 and the wall piece 2. There are skeleton 1 and skeleton 2, skeleton 1 includes horizontal skeleton 1 and vertical skeleton 1 connected to each other, skeleton 2 includes horizontal skeleton 2 and vertical skeleton 2 connected to each other, and described skeleton 1 and skeleton 2 pass through corresponding longitudinal skeletons. Frame 1 is connected with longitudinal frame 2, and longitudinal frame 1 and longitudinal frame 2 are connected by a keyed connection structure. The keyed connection structure includes a keyed piece connected to the inner end face of longitudinal frame Two card slot pieces on both sides of the outer end face.

The cross section of the card slot sheet is an "L"-shaped structure, the card slot sheet includes a fixing part and a connecting part, the connecting part is provided with a slot hole, and the fixing part is provided with a screw hole.

The card key sheet includes a bottom plate, wing plates connected to both ends of the bottom plate, and an "L"-shaped groove is provided at the connection between the bottom plate and the wing plates.

The bending parts on both sides of the longitudinal frame 1 are provided with vertical holes, and the positions of the vertical holes correspond to the positions of the key clips.

The ends of the connecting parts are provided with cut corners.

The card key piece and the card slot piece correspond to each other in the vertical position and are aligned with each other in the horizontal position.

The width of the wing plate is not less than the width of the slot hole, and the height of the wing plate is equal to the height of the slot hole.

The card slot sheet is fixedly connected to the second longitudinal frame through the fixing part, the card key sheet is fixedly connected to the first longitudinal frame through the bottom plate, and the outer end surface of the wing plate is in contact with the inner side of the first longitudinal frame.

The technical scheme of the present invention has the following positive effects: first, a plurality of card slot pieces are made, and the card slot pieces are metal stamping parts made of steel, and rivets or self-tapping screws are used to fix them to the outer side of the second longitudinal frame at the end of the second frame On both sides of the end face, the card slot pieces are fixedly connected to the second longitudinal frame through the fixing part, and the card slot sheets on the second longitudinal frame at each end are in multiple groups. Then make a plurality of card key sheets, which are metal stamping parts made of steel, and are fixed to the inner end face of the longitudinal frame one at the end of the frame one with rivets or self-tapping screws, and the card key sheets are fixedly connected in the longitudinal direction through the bottom plate On the first frame, the outer end surface of the wing plate is in contact with the inner side surface of the first longitudinal frame. Vertical holes are provided on the bending parts on both sides of the longitudinal frame 1, and the vertical holes are used for the connecting parts of the card slot pieces to extend into, and then the outer parts of the frame 1 and the frame 2 are respectively covered with OSB board, breathing paper, wooden keel, The external cladding board forms two independent composite wall pieces, which are then packaged and sent to the installation site. On the construction site, the skeleton is close to the second frame, that is, the longitudinal frame is close to the longitudinal frame 2, and the connecting part of the card slot sheet is passed through the vertical hole. Since the end of the connecting part is provided with a cut angle, the card key sheet will be pushed up. The side plate of the bottom plate is provided with an "L"-shaped groove at the connection between the bottom plate and the wing plate, so that a gap is formed between the card slot sheet and the longitudinal frame 2, and then with the deepening of the card slot sheet, the two wings of the card key sheet It gradually falls into the slot hole from the right end, and finally the two wings of the card key sheet all fall into the slot hole of the card slot sheet. As a result, due to the blocking effect of the flaps of the card key sheet on the card groove of the card slot sheet, the card slot sheet cannot be pulled away from the key card sheet, and the frame two cannot be pulled away from the frame one. The two wall pieces are connected as a whole. Since the structure of double-card slot sheet and double-card key sheet is adopted at the same elevation, the wall sheet connection also has out-of-plane bending stiffness. Moreover, the length of the vertical hole is basically the same as the vertical height of the connecting portion of the card slot sheet, and the possible relative displacement of the wall sheet 1 and the wall sheet 2 in the vertical direction is also extremely small. Due to the use of vertical holes, the bearing capacity of the longitudinal frame 1 is minimally affected. Thus, the solid connection between the wall piece 1 and the wall piece 2 is realized. The connection process has no effect on the pre-assembled elements in each wall piece, and truly achieves the complete assembly construction goal of the wall.
