The utility model can be achieved through the following technical solutions:
1. the slide type metal connecting piece, characterized in that metal connecting piece is made of tongue-and-groove steel and tenon steel, and with cunning The form of shifting makes two blocks of tenon steel be mutually twisted integrated connection part of the fastening composition with some strength.
2. the slide type metal connecting piece, characterized in that connector raw material are Q235 steel.The groove of tongue-and-groove steel and The tenon of tenon steel is all made of milling cutter progress Milling Process and is made, and machining tool can be used in Milling Process process or numerical control adds It completes at work center.
3. the slide type metal connecting piece, characterized in that two blocks of tenon steel are fixed to by tapping screw on CLT wallboards.
4. the slide type metal connecting piece, characterized in that two blocks of tenon steel are respectively provided with screw hole, for installing self tapping spiral shell Nail.Screw hole is process using bench drill or numerically-controlled machine tool, and the size in hole is depending on the tapping screw diameter of selection.
5. the tapping screw for fixing tenon steel, characterized in that intensity is 8.8 grades, and tapping screw hammers into depth Depending on foundation CLT wall size sizes, wall of being subject to has enough bonding strengths after the connection of slide type metal connecting piece.
6. the CLT wallboards that the slide type metal connecting piece is connected, characterized in that the number of plies of orthogonal laminated wood is n-layer, The odd-level laminate specification wood of n >=3, orthogonal laminated wood is vertical arrangement, and even level laminate specification wood is horizontal arrangement.
7. the CLT wallboards that the slide type metal connecting piece is connected, characterized in that constitute the vertical specification of CLT wallboards The thickness of wood and lateral specification wood is 18~39mm, and width is 140~290mm, width-thickness ratio>4.
8. the CLT wallboards that the slide type metal connecting piece is connected, characterized in that in CLT wallboard center sides position Slot is opened up, for installing tongue-and-groove steel, slot and tenon steel are wide, twice of the length of connector, and depth is one group of slide type gold Belong to the overall thickness after the mutual clamping of connector.
The advantageous effect of this patent utility model:
The slide type connector of the CLT timber buildings walls of the utility model, it is novel, simple in structure, facilitate reality With, it can be achieved that simple and quick assembled in situ installation and can repeated disassembled and assembled, can not only shorten the construction period, and can effectively ensure that knot The excellent stress performance of structure reduces operating expenses.
