Embodiment 1

[0041] A straw-steel system fabricated wall, which consists of a set of straw boards 1, and the joints of the two sides of the straw boards are L-shaped structure, 6-shaped structure or 9-shaped structure. The straw boards are connected to form an L-shaped wall or a T-shaped wall or a cross-shaped wall. The upper and lower sides of the straw boards are covered with C-shaped steel sleeves 2, and the inflection points of the straw boards pass through the L-shaped steel 14 and In the C-shaped steel sleeve welding, the straw slabs are welded to the C-shaped steel sleeve through the strip steel plate where there is no inflection point, and the cross-shaped area in the middle of the straw slabs intersects is welded with the light steel plate 4 The C-shaped steel sleeve welding, the light steel plate is the steel plate used for the tic-tack grid in the outer steel frame of the straw plate, the straw plate, the C-shaped steel sleeve, the L-shaped steel, the strip steel plate, the The o...

Embodiment 2

[0047] A manufacturing method of fabricated wall using the straw-steel system of claim 1, the method comprising the following steps:

[0048] (1) The prefabricated straw board 1 is a fibrous material made of crop straws, and cemented materials are added to make a mixture, which is compressed and molded by a mold. The thickness of the straw board is equal to the width of the channel steel groove selected;

[0049] (2) The channel steel adopts C-shaped steel 2. The length of the C-shaped steel at the upper and lower ends of the wall is equal to the width of the wall. The length of the C-shaped steel at the upper and lower ends of each node is equal to the length of the wall plus the length of the node, and the remaining C The length of the profiled steel is equal to the length of the wall; firstly place the C-shaped steel horizontally on the ground during processing. According to the layout of the wall, the flanges and webs of the part of the C-shaped steel need to be cut to facilitat...

Abstract

The invention provides a straw-steel system prefabricated wall and a joint connecting method. For a long time, China steel structure is made of connecting steel plates, shaped steel and the like to form basic components, and then transported to a construction site to be installed and connected into an overall structure. Therefore, in the steel structure, connection occupies a very important position, and any steel structures can meet the connection problems. The straw-steel system prefabricated wall comprises a group of straw plates (1), the straw plates are connected to form an L-shaped wallor a T-shaped wall or a cross-shaped wall, C-shaped steel sleeves (2) sleeve the upper and lower faces of the straw plates, the positions of straw plate intersection with inflection points are weldedto the C-shaped steel sleeves through L-shaped steel (14), the positions of straw plate intersection without the inflection points are welded to the C-shaped steel sleeves through strip-shaped steel plates, and plastering layers (15), fireproof layers (16) and waterproof layers (17) are successively arranged on the outer surfaces of the straw plates, the C-shaped steel sleeves, the L-shaped steel,the strip-shaped steel plates and light steel plates. The joint connecting method is used for the prefabricated wall.

Description

Technical field: [0001] The invention relates to a straw-steel system assembled wall and a node connection method thereof. Background technique: [0002] For a long time, steel structure in our country is an integral structure made of steel plate, section steel, etc. through connection, and then transported to the construction site for installation and connection. Therefore, in steel structure, connection occupies a very important position, and any steel structure will encounter connection problems. Welding is the main connection method for modern steel structures. However, the mechanical properties of the steel in the heat-affected zone of the weld are changed, the material becomes brittle, and residual stress and residual deformation inevitably occur. Once cracks occur, they may spread rapidly. The entire section is especially brittle at low temperature. Bolt connection needs to make holes for assembly and installation, which will increase the workload and require higher manu...
