Description

Technical Field

[0001] The present invention belongs to the technical field of building support structures, and particularly relates to an earthquake-resistant precast embedded part. Background Art

[0002] A glass curtain wall refers to a building exterior enclosure structure or decorative structure in which the support structure system can have a certain displacement ability relative to the main structure and does not bear the actions applied to the main structure.

[0003] Among them, the embedded part in the support structure system is a main component. The embedded part is a component pre-installed in a concealed project, that is, a component placed during the structure pouring, and is used for the lap joint when building the upper structure.

[0004] When installing the curtain wall keel, the connecting piece needs to be welded and fixed to the embedded steel plate. Since the welder performs manual work at high altitude, the welding quality is greatly affected by the welder's skills and the environment. Moreover, the vibration on the curtain wall will be transmitted to the keel and the connecting piece, causing the solder joints to become loose, and at the same time, causing the separation between the embedded steel plate and the precast concrete, affecting the stability of the curtain wall assembly. Summary of the Invention

[0005] The present invention provides an earthquake-resistant precast embedded part to solve the technical problems of the solder joint detachment of traditional keel welding and the detachment at the connection between the embedded part and the precast concrete in the related art.

When the insertion plate is inserted into the plugging gap, the end of the insertion plate is deformed and abuts against and is connected to the outer surface of the inner convex block;

[0009] The anchoring member includes a sleeve and a guide cone. The end of the sleeve away from the steel plate is a closed structure, and through grooves are provided on four sides of the sleeve close to the closed end. The guide cone is provided on the inner wall of the closed end of the sleeve, and the direction of the guide cone is consistent with the length direction of the sleeve.

[0010] The fixing member includes a screw member and a locking nut. The length direction of the screw member is consistent with the length direction of the anchor member. The locking nut is installed on one end of the screw member close to the positioning plate. The outer wall of the locking nut is abutted and connected to the outer surface of the positioning plate.

[0011] The screw rod comprises a threaded portion and a bent portion, wherein the bent portion is arranged on the end of the threaded portion. When the screw rod is installed to the sleeve along its length direction, the end of the bent portion is abutted against and connected to the outer wall of the guide cone, and the bent portion is bent toward the through grooves on four sides with the axis of the screw rod as the center line, and the end of the bent portion extends out of the outer wall of the sleeve, and the bent portion and the threaded portion form an anchor hook-like structure.

[0012] As a further optimization scheme of the present invention, the vertical cross-section of the inner protrusion is a trapezoidal structure, and the vertical cross-section of the inner protrusion close to the C-shaped steel frame is composed of a guide portion and a vertical portion, the guide portion is arranged above the vertical portion, and the guide portion is a "丿" type structure.

[0013] As a further optimization solution of the present invention, a thread is provided on the inner wall of one end of the sleeve close to the C-shaped steel frame, and the thread is cooperatively connected with the threaded portion.

[0014] As a further optimization solution of the present invention, the waist-round groove is distributed in an eight-shaped shape on the positioning plate, and the end of the threaded portion is connected to the groove wall of the waist-round groove.

[0018] As a further optimization solution of the present invention, a matching groove is provided on a side of the square gasket close to the panel, and the groove shapes of the matching groove and the anti-slip groove fit each other.

[0019] As a further optimization solution of the present invention, an expansion head is fixedly connected to one end of the sleeve away from the steel plate.

[0020] As a further optimized solution of the present invention, a screw hole is formed in the inner wall of the C-shaped steel frame close to the inner convex block, and a self-tapping screw is arranged in the screw hole, and the end of the self-tapping screw extends out of the outer wall surface of the steel plate member.

[0021] The beneficial effects of the present invention are as follows:

[0022] The present invention uses an inwardly screwed screw member as the connection method between the anchor bar and the curtain wall keel lap joint, replacing the traditional welding connection method, greatly reducing the potential safety hazards in curtain wall construction, and at the same time having good durability and seismic resistance, so that the curtain wall has high connection strength and strong deformation bearing capacity of the connecting member;

[0023] The end of the screw member will form an anchor hook structure during the screwing process. The anchor hook structure can effectively conduct vibrations in multiple directions into the precast concrete, reducing the influence of vibrations on the connection between the embedded part and the precast concrete, and improving the filtering effect of the embedded part on multi-directional vibrations transmitted by the curtain wall;

[0024] The positioning plate member installed on the embedded part can be screwed by a nut to abut against the steel plate member, causing the insertion plate extending from the lower side of the positioning plate member to deform, forming an outer eight-shaped connection structure. The abutment between the deformed insertion plate and the steel member can cancel out horizontal and vertical vibrations, improving the stability of the curtain wall connected by the embedded part.

[0038] On one side of the positioning plate member 300 close to the C-shaped steel frame 110, there is an insertion plate 340, and the end face of the insertion plate 340 is perpendicular to the outer surface of the positioning plate member 300. The length direction of the insertion plate 340 is the same as the length direction of the steel plate member 100. When the insertion plate 340 is inserted into the insertion gap, the end of the insertion plate 340 deforms and abuts against and connects to the outer surface of the inner convex block 120;

[0039] The anchoring member 200 includes a sleeve 210 and a guiding cone 230. One end of the sleeve 210 away from the steel plate member 100 is a closed structure, and through grooves are provided on four sides of the sleeve 210 close to the closed end.

[0042] The inner side wall of one end of the sleeve 210 close to the C-shaped steel frame 110 is provided with threads, and the threads are in mating connection with the threaded portion 411.

[0043] The oval slots 330 are distributed in an eight-character shape on the positioning plate member 300, and the end of the threaded portion 411 abuts against and connects to the groove wall of the oval slots 330.

[0044] The positioning plate member 300 includes a panel 310 and a keel lapping frame 320, and the keel lapping frame 320 is fixedly connected to the outer surface of the panel 310 on the side away from the steel plate member 100. The end face of the keel lapping frame 320 is perpendicular to the outer surface of the panel 310.

[0045] On one side of the panel 310 away from the socket 340, an anti-slip groove is provided along the length direction. The fixing member 400 further includes a square gasket 420. The square gasket 420 is sleeved on the threaded portion 411 of the screw member 410, and both sides of the square gasket 420 respectively abut against the outer wall of the locking nut 430 and the panel 310. A mating groove is provided on one side of the square gasket 420 close to the panel 310, and the groove shapes of the mating groove and the anti-slip groove are engaged and matched with each other.

[0046] On the inner wall of one side of the C-shaped steel frame 110 close to the inner convex block 120, a screw perforation 130 is provided, and a self-tapping screw 700 is provided in the screw perforation 130. The end of the self-tapping screw 700 extends out of the outer wall surface of the steel plate member 100.

[0047] It should be noted that for this earthquake-resistant prefabricated embedded part, when in use, this embedded part is applied to the installation of a glass curtain wall. As Figure 7 shown, when installing, it is necessary to first set up a pouring formwork 500 on the outer eaves side close to the curtain wall. On the side of the pouring formwork 500 close to the installation of the curtain wall outer eaves, measure the installation position of the embedded part, fit the open side of the C-shaped steel frame 110 to the inner wall of the pouring formwork 500, and use the self-tapping screw 700 to pass through the screw perforation 130 of the C-shaped steel frame 110, so that the end of the self-tapping screw 700 is connected to the pouring formwork 500, and the position of the C-shaped steel frame 110 and the pouring formwork 500 is fixed. Then, insert the screw member 410 through the through hole reserved on the pouring formwork 500. The bent portion 412 of the screw member 410 abuts against the guiding cone 230, but the bent portion 412 does not become bent along the surface of the guiding cone 230. At this time, the threaded portion 411 of the screw member 410 is not completely screwed into the thread groove in the sleeve 210;

[0048] Then lay the prefabricated inner steel frame 600 in the pouring formwork 500. After laying, pour the prefabricated concrete material into the pouring formwork 500 to fill the inner side of the pouring formwork 500, and vibrate it to make there be no air cavity inside. After pouring, continue to screw the screw member 410 into the sleeve 210. The bent portion 412 at its end is bent due to the abutting and extrusion of the guiding cone 230, so that the bent portion 412 is extruded outward through the through groove at the end of the sleeve 210, as Figure 3 shown, forming a four-claw anchor hook structure. The anchor hook structure can transfer the vibration of the curtain wall to the deeper precast concrete through the screw member 410. At the same time, the anchor hook structure can disperse the transfer effect into multiple directions, improving the filtering effect of the embedded part on multi-directional vibration;

[0049] After the concrete solidifies, the casting template 500 is removed. At this time, the open end of the C-shaped steel frame 110 is flush with the end surface of the solidified concrete. At this time, the threaded portion 411 of the screw member 410 extends out of the outer wall of the C-shaped steel frame 110, and a positioning plate 300 is sleeved on its end. The plug plate 340 end of the positioning plate 300 is inserted into the insertion gap, first abutting against the top of the guide portion of the inner protrusion 120, and then a square gasket 420 and a locking nut 430 are sleeved on the end of the threaded portion 411. The matching groove on the square gasket 420 and the anti-slip groove on the panel 310 are engaged and fixed, and the locking nut 430 abuts against the square gasket 420. The screwing in of the locking nut 430 can drive the entire panel 310 to move to one side of the C-shaped steel frame 110, so that the plug plate 340 is deformed along the outer wall of the guide portion to form a Figure 4 The structure shown in the figure, the wall surface of the final panel 310 is attached to the outer wall of the C-shaped steel frame 110, and the plug plate 340 forms an eight-shaped outward expansion structure, so that the panel 310 is stably clamped in the C-shaped steel frame 110, and the abutting connection relationship between the plug plate 340 and the inner protrusion 120 can form a stable longitudinal shock-absorbing structure, and the abutting connection relationship between the plug plate 340 and the C-shaped steel frame 110 can form a stable transverse shock-absorbing structure. When the curtain wall is vibrated, the two shock-absorbing structures can ensure that the panel 310 is stably connected to the C-shaped steel frame 110, and the excess vibration is transmitted to the side of the poured concrete, thereby improving the stability of the curtain wall connected by the embedded parts;

[0050] The keel lap frame 320 on the panel 310 can overlap and install the curtain wall keel. At the same time, after the threaded portion 411 of the screw member 410 is screwed in, it partially extends out of the outside of the locking nut 430, and then the keel frame installed in the curtain wall is directly connected through the screw member 410, avoiding the need to weld the keel to the bracket during traditional installation. The introduction of the screw member 410 and the keel lap frame 320 expands the connection points of the curtain wall to multiple points, and the curtain wall connection strength is high and the deformation resistance of the connecting parts is strong.

[0051] The embodiment of the present embodiment is described above in conjunction with the accompanying drawings, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the present embodiment, ordinary technicians in this field can also make many forms without departing from the purpose of the present embodiment and the scope of protection of the claims, all of which are within the protection of the present embodiment.
