Referring to fig. 1, fig. 1 is a schematic view of a connection structure of a steel plate concrete wall and a reinforced concrete wall in an embodiment, an embodiment of the present invention provides a building structure wall, which includes a connection structure 200 and a steel plate concrete wall 100 and a reinforced concrete wall 300 connected by the connection structure 200.
It can be understood that the steel plate concrete wall 100 and the reinforced concrete wall 300 are connected in a straight line shape through the connection structure 200, so that the connection structure 200 forms better wall end constraint for the steel plate concrete wall 100 and the reinforced concrete wall 300, and the integrity of the wall connection area is obviously enhanced.
In some embodiments, the connection structure includes a frame structure 210, a first connection member provided at one side of the frame structure 210, which extends into the interior of the steel plate concrete wall 100, and a second connection member provided at the other side of the frame structure 210, which extends into the interior of the reinforced concrete wall 300.
It can be understood that the connection structure 200 includes the frame structure 210, and the frame structure 210 can directly transmit the internal force on the steel panel of the steel plate concrete wall 100 to the steel bar of the reinforced concrete wall 300, so as to effectively improve the cracking of the concrete at the connection interface; by welding the first connecting piece and the second connecting piece on the two sides of the frame structure 210, the reinforcing steel bars which are densely arranged in the connecting area are decomposed into two parts, the reinforcing steel bars which are locally densely arranged are evacuated, and construction is facilitated.
Further, in order to enhance the strength of the connection structure 200, concrete is poured into the frame structure 210.
In some embodiments, the frame structure 210 includes a first end plate 211, a second end plate 213, and an outer web 212 connected to ends of the first end plate 211 and the second end plate 213, the first connecting member is disposed on the first end plate 211, the second connecting member is disposed on the second end plate 213, and an inner web 240 is disposed between the first end plate 211 and the second end plate 213.
Specifically, the number of the outer webs 212 is two, and the outer webs are respectively connected to two ends of the first end plate 211 and two ends of the second end plate 213, so that the first end plate 211, one of the outer webs 212, the second end plate 213 and the other outer web form a rectangular frame structure, the width of the first end plate 211 is equal to the thickness of the steel plate concrete wall 100, the width of the second end plate 213 is equal to the thickness of the reinforced concrete wall 300, the height of the first end plate 211 is equal to the height of the steel plate concrete wall 100, and the height of the second end plate 213 is equal to the height of the reinforced concrete wall 300.
In actual construction, the first end plate 211 and the outer web 212, and the second end plate 213 and the outer web 212 are all connected by full penetration welds, the first end plate 211 and the inner web 240 are connected by double-sided corner welds, the second end plate 213 and the inner web 240 are connected by full penetration welds, and weld gaskets are disposed on the back of the full penetration welds, that is, the weld gaskets are disposed on four inner corners of the frame structure 210.
In some embodiments, the thickness of the first end plate 211 and the second end plate 213 is equal to or greater than 40mm, and the first end plate 211 and the second end plate 213 are both made of Z-steel, and the ratio of the distance between the first end plate 211 and the second end plate 213 to the distance between the two outer webs 212 is 0.5-4: 1. Preferably, the thickness of the first end plate 211 and the second end plate 213 is 40mm, and the first end plate 211 and the second end plate 213 need to have a large rigidity as a main conductor of internal forces on both sides, so that a thick steel plate of 40mm is used for the first end plate 211 and the second end plate 213, but when the thickness of the steel plate is not less than 40mm and a tensile force in the thickness direction of the plate is applied, lamellar tearing is easily generated during welding, so that a steel material resisting lamellar tearing, i.e., Z-direction steel, needs to be used; the ratio of the distance between the first end plate 211 and the second end plate 213 to the distance between the two outer webs 212 is 0.5-4:1, and if the ratio is less than 0.5:1, on one hand, the distance is too small, the construction difficulty of pouring concrete in the frame structure 210 is large, and on the other hand, the section inertia moment of the frame structure 210 is small, and the resistance capability is poor; if the ratio is greater than 4:1, the distance between the first end plate 211 and the second end plate 213 is too long, so that the internal force on the steel plate at the side of the steel plate concrete wall cannot be quickly transmitted to the steel bar at the side of the steel plate concrete wall, and the condition of concrete cracking at the connecting interface cannot be well improved.
Further, in order to ensure the uniformity of internal force conduction, the first shear nails 250 are uniformly distributed on the first end plate 211 at equal intervals, the anchor bars 260 are uniformly distributed on the second end plate 213 at equal intervals, and the interval between two adjacent anchor bars 260 is greater than the interval between two adjacent first shear nails 250.
