Description

Technical Field

[0001] The utility model belongs to the technical field of concrete wall panels, and particularly relates to a concrete wall panel structure of a shear wall with embedded steel supports. Background Technique

[0002] When the shear wall with embedded steel supports is connected to the beam at the bottom, the embedded steel plates extending from the inside of the shear wall are mostly welded to the steel beam for connection, and finally concrete is poured between the shear wall and the steel beam. This connection method is prone to welding defects, requires welders with high skills to operate, has low efficiency, and increases construction costs. Therefore, we designed a concrete wall panel structure of a shear wall with embedded steel supports, which uses angle steel for positioning and is fastened with bolts, making the connection between the steel plate extending from the shear wall and the steel beam simple and reliable, without welding, and improving construction efficiency. Content of the Utility Model

[0003] The purpose of the utility model is to provide a concrete wall panel structure of a shear wall with embedded steel supports, which has the advantages of using angle steel for positioning and being fastened with bolts, making the connection between the steel plate extending from the shear wall and the steel beam simple and reliable, without welding, and improving construction efficiency, so as to solve the above problems in the background technique.

[0004] The technical solution of the utility model to solve the above technical problems is as follows: A concrete wall panel structure of a shear wall with embedded steel supports includes two embedded steel plates extending from the inside of the shear wall to the outside of the bottom of the shear wall and two backing plates installed on the top of the steel beam through a plurality of long bolts I. A connecting steel plate is welded to the bottom of the embedded steel plate and fits on the top of the backing plate. On both sides of the top of the backing plate, wide angle steels that fit on the surface of the connecting steel plate are slidably connected. Two symmetric long slots II are opened at the top of the wide angle steel. Long slots I are opened at the four corners of the top of the connecting steel plate. Four long bolts II penetrate through the steel beam, and one end of the long bolt II passes through the backing plate, long slot I and long slot II and extends to the top of the connecting steel plate.

[0005] Preferably, anti - detachment sliding slots are opened on both sides of the top of the backing plate, and anti - detachment sliding blocks fixedly connected to the bottom of the wide angle steel are slidably connected in the inner cavity of the anti - detachment sliding slots.

[0006] Preferably, limiting slots for the wide angle steel to enter are opened on both sides of the connecting steel plate.

[0007] Preferably, anti - slip plates are sleeved on the surfaces of the front and rear long bolts II, and the bottom of the anti - slip plate contacts the top of the connecting steel plate.

[0008] Preferably, a notch is opened on one side of the wide angle steel, and the notch is adapted to the embedded steel plate.

[0009] The beneficial effects of the utility model are:

[0010] 1. The utility model fixes and installs a backing plate on a steel beam through a first long bolt. Then, a connecting plate is welded to the bottom of the embedded steel plate extending from the shear wall, so that the connecting plate fits on the top of the backing plate. Then, two wide angle steels are picked up, and the anti-disengagement sliding grooves slide in the inner cavity of the anti-disengagement sliders until the wide angle steels move into the inner cavity of the limit grooves to limit the connecting plate. A second long bolt is passed through the steel beam to the top of the connecting plate and a nut is screwed on, replacing the traditional welding method. The firmness is more reliable, and the purpose of using angle steels for limiting and bolts for fastening can be achieved, making the connection between the steel plate extending from the shear wall and the steel beam simple and reliable without welding, thus improving the construction efficiency.

[0011] 2. Through the setting of the anti-slip plate, the anti-slip plate is fastened and fitted on the top of the wide angle steel through the nut on the second long bolt, increasing the friction between the nut and the wide angle steel in direct contact, ensuring that the wide angle steel will not move randomly, and improving the stability of the wide angle steel fitting on the surface of the connecting plate.

[0012] 3. Through the coordinated use of the anti-disengagement sliding grooves and the anti-disengagement sliders, after the anti-disengagement sliders slide in the inner cavity of the anti-disengagement sliding grooves, the wide angle steel will not be disengaged from the backing plate, ensuring the firmness degree after the wide angle steel limits the connecting plate.

[0019] In the following, embodiments of the concrete wall panel structure of the concealed steel brace shear wall of the present utility model will be described with reference to the accompanying drawings.

[0020] Figures 1-3 The concrete wall panel structure of the concealed steel brace shear wall showing an embodiment of the present utility model includes two concealed steel plates 2 extending to the outside of the bottom of the shear wall 1 in the shear wall 1 and two backing plates 6 mounted on the top of the steel beam 4 by a plurality of first long bolts 5. A connecting steel plate 3 fitting against the top of the backing plate 6 is welded to the bottom of the concealed steel plate 2. Wide angle steel 7 fitting against the surface of the connecting steel plate 3 is slidably connected to both sides of the top of the backing plate 6. An opening 15 is provided on one side of the wide angle steel 7, and the opening 15 is adapted to the concealed steel plate 2. Limiting grooves 13 for the wide angle steel 7 to enter are provided on both sides of the connecting steel plate 3. Two symmetric long grooves 9 are provided on the top of the wide angle steel 7. Long grooves 8 are provided at the four corners of the top of the connecting steel plate 3. Four second long bolts 10 are penetratingly provided on the steel beam 4. Anti-slip plates 14 are sleeved on the surfaces of the front and rear second long bolts 10. The bottom of the anti-slip plate 14 contacts the top of the connecting steel plate 3. Through the setting of the anti-slip plate 14, the anti-slip plate 14 is firmly attached to the top of the wide angle steel 7 by the nuts on the second long bolts 10, increasing the friction between the nuts and the wide angle steel 7 in direct contact, ensuring that the wide angle steel 7 will not move randomly, and improving the stability of the wide angle steel 7 fitting against the surface of the connecting steel plate 3. One end of the second long bolt 10 passes through the backing plate 6, the long groove 8 and the long groove 9 and extends to the top of the connecting steel plate 3. Anti-slip chutes 11 are provided on both sides of the top of the backing plate 6. Anti-slip blocks 12 slidably connected to the inner cavity of the anti-slip chutes 11 are fixedly connected to the bottom of the wide angle steel 7. Through the cooperation of the anti-slip chutes 11 and the anti-slip blocks 12, after the anti-slip blocks 12 slide in the inner cavity of the anti-slip chutes 11, the wide angle steel 7 will not be separated from the backing plate 6, ensuring the firmness of the wide angle steel 7 in limiting the connecting steel plate 3.

[0021] Working principle: When the present utility model is in use, the user fixes the backing plate 6 on the top of the steel beam 4 according to pre-measurement. When the shear wall 1 is placed on the top of the steel beam 4, the connecting steel plate 3 extending from the concealed steel plate 2 at the bottom of the shear wall 1 fits against the top of the backing plate 6. Hold the wide angle steel 7 and insert the anti-slip blocks 12 at the bottom of the wide angle steel 7 into the inner cavity of the anti-slip chutes 11 on the backing plate 6, and push the wide angle steel 7 to fit against the surface of the connecting steel plate 3 until the wide angle steel 7 enters the inner cavity of the limiting groove 13. Then pick up the second long bolt 10 and pass it through the steel beam 4, the long groove 8 and the long groove 9 to the top of the connecting steel plate 3, put the anti-slip plate 14 on the surface of the second long bolt 10, and tighten the nut.

[0022] In summary: For the concrete wall panel structure of the embedded steel brace shear wall, the backing plate 6 is fixedly installed on the steel beam 4 through the long bolt 5. Then, the bottom of the embedded steel plate 2 extending from the shear wall 1 is welded to the connecting steel plate 3, so that the connecting steel plate 3 fits on the top of the backing plate 6. Then, pick up two wide angle steels 7, and slide the anti-disengagement chute 11 in the inner cavity of the anti-disengagement slider 12 until the wide angle steel 7 moves into the inner cavity of the limit groove 13 to limit the connecting steel plate 3. Pass the long bolt 2 10 through the steel beam 4 to the top of the connecting steel plate 3 and screw on the nut. Instead of the traditional welding method, the firmness is more reliable. By using angle steel for limiting and cooperating with bolt fastening, the connection between the steel plate extended from the shear wall and the steel beam is simple and reliable without welding, achieving the purpose of improving construction efficiency.
