Description

Technical Field

[0001] This application relates to the field of cantilever slabs, and particularly to a combined support structure for cantilever slabs. Background Art

[0002] To meet the diversity of building shapes, in high-rise and super high-rise buildings, structural cantilever slabs are often designed. The extra-long cantilever slabs that match the building's exterior curtain wall have become a common practice in the current building system. A cantilever slab is supported or fixed at only one end, with the other side or several sides cantilevered. There is no direct vertical support under the slab, and the slab relies on itself or the stress bars in the slab to bear the load.

[0003] In the related art, the combined support structure of a cantilever slab includes a wall. Inside the wall, six groups of equally spaced load-bearing members are arranged. The load-bearing members are used to connect the upper reinforcing bars and the lower reinforcing bars. The bottom ends of the upper reinforcing bars and the lower reinforcing bars are both sleeved with connecting members. The bottom ends of the connecting members are installed with fixing plates. A trapezoid is formed among the three components of the lower reinforcing bar, the upper reinforcing bar, and the fixing plate. A casting bottom plate is installed on the outer wall of the wall. Two groups of side plates arranged side by side are installed on the top of the casting bottom plate. A baffle is installed on the top of the casting bottom plate, and one side of the baffle is attached to the bottom ends of the two side plates. The casting bottom plate, the side plates, and the baffle form a casting formwork. The upper reinforcing bar, the lower reinforcing bar, and the fixing plate are all located in the internal space of the casting formwork. Concrete is poured inside the casting formwork. After the operator installs the upper reinforcing bar, the lower reinforcing bar, and the fixing plate, then installs the casting formwork and pours the concrete. After the concrete solidifies, the casting formwork is removed to form a cantilever slab.

[0004] Regarding the above related art, the inventor believes there are the following defects. When the operator installs the casting formwork and pours the concrete, voids are likely to be generated in the internal space of the casting formwork, and the voids still exist after the concrete solidifies, reducing the structural strength of the cantilever slab and shortening the service life of the cantilever slab. Summary of the Invention

[0005] To improve the above problems, this application provides a combined support structure for a cantilever slab.

[0006] The combined support structure for a cantilever slab provided in this application adopts the following technical solutions:

[0008] By adopting the above technical solution, when the operator installs the upper steel bar, the lower steel bar and the fixing plate, the pouring box is installed on the wall, and the concrete is transported into the pouring box through the second feeding pipe and the first feeding pipe. When the pouring box is filled with concrete, the conveying of the concrete is stopped. After the concrete solidifies, the pouring box is removed, reducing the possibility of voids generated in the pouring box after the concrete solidifies, improving the structural strength of the cantilever slab, and extending the service life of the cantilever slab.

[0009] Preferably, a positioning stop edge is fixedly connected to the pipe wall of the first feeding pipe, a positioning groove is formed on the hole wall of the feeding hole, the positioning stop edge abuts against the bottom of the positioning groove, a protective sleeve is arranged on the first feeding pipe, the protective sleeve abuts against the inner wall of the pouring box, the first feeding pipe slides relative to the protective sleeve, and a control assembly is arranged on the first feeding pipe for controlling the relative fixation of the protective sleeve and the first feeding pipe.

When the operator conveys the concrete into the pouring box, the protective sleeve can protect the first feeding pipe, reducing the possibility of the concrete contacting the pipe wall of the first feeding pipe, and facilitating the removal of the first feeding pipe driven by the pouring box when the operator removes the pouring box.

[0011] Preferably, the control assembly includes a control rod, a control block and a control torsion spring.

[0012] By adopting the above technical solution, under natural conditions, the control torsion spring controls the rotation of the control rod, the rotation of the control rod can drive the rotation of the control block, so that the control block slides into the second control groove, the control block limits the protective sleeve, so that the protective sleeve and the first feeding pipe are relatively positioned, facilitating the protection of the first feeding pipe by the protective sleeve. When the staff needs to remove the pouring box, rotate the control rod to make the control block slide out of the second control groove, release the limit of the second control groove on the control block and move the first feeding pipe, and then remove the pouring box.

[0013] Preferably, one end of the second feed pipe facing the pouring box is provided with a positioning hole for the part of the control rod extending out of the first feed pipe to be embedded.

An auxiliary bolt is arranged on the auxiliary baffle, and the auxiliary bolt passes through the auxiliary baffle and is threadedly connected with the bottom of the auxiliary groove.

[0014] By adopting the above technical solution, when the operator installs the second feed pipe on the pouring box, move the second feed pipe to make the positioning rod embedded in the positioning hole. The positioning rod can limit the second feed pipe, and the movement of the second feed pipe makes the auxiliary baffle abut against the groove wall of the auxiliary groove. Screw in the auxiliary bolt to relatively position the auxiliary baffle and the groove wall of the auxiliary groove, so as to relatively position the second feed pipe and the pouring box.

[0015] Preferably, it further includes a support rib. The support rib slides relative to the protective sleeve, and the support rib abuts against the inner wall of the protective sleeve.

After moving the second feed pipe away from the pouring box, rotate the control rod to drive the control block to rotate. After the control block slides out of the second auxiliary groove, move the first feed pipe away from the pouring box. Then put the support rib into the protective sleeve and convey concrete into the protective sleeve. Wait for the concrete in the protective sleeve to solidify, and the support rib is relatively fixed to the protective sleeve.

The swing ball is made of rubber and abuts against the pouring box. A torsion spring is arranged on the rotation axis of the swing rod.

[0018] By adopting the above technical solution, when the concrete is conveyed into the pouring box, the operator can pull the swing rod to drive the swing ball to move. And the swing rod rotates under the action of the torsion spring.

[0020] By adopting the above technical solution, when the swing rod drives the swing ball to impact the pouring box under the action of the torsion spring, the vibration of the pouring box drives the vibration of the rolling ball, making the rolling ball abut against the inner wall of the auxiliary cavity, increasing the vibration amplitude of the pouring box, and further making the concrete in the pouring box evenly distributed.

[0021] Preferably, an auxiliary frame is arranged on the pouring box, an auxiliary rod is rotatably connected in the auxiliary frame, an auxiliary pad is wound around the auxiliary rod, and the auxiliary pad is attached to the surface of the pouring box.

[0022] By adopting the above technical solution, when the concrete conveying in the pouring box is completed, the operator can pull out the auxiliary pad to make it fit the surface of the pouring box. The auxiliary pad can provide heat to the pouring box, increasing the solidification speed of the concrete and facilitating the fabrication of the cantilever slab.

[0024] By adopting the above technical solution, the auxiliary members can reduce the possibility of gaps generated between the pouring box and the wall. When the operator installs the pouring box, move the pouring box to make the auxiliary members abut against the wall, then screw in the connecting bolt so that the connecting bolt passes through the connecting plate and the auxiliary member and is threadedly connected to the wall to complete the installation of the pouring box.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1.

When the pouring box is filled with concrete, stop the concrete conveying. After the concrete solidifies, remove the pouring box, reducing the possibility of voids generated in the pouring box after the concrete solidifies, increasing the structural strength of the cantilever slab and extending the service life of the cantilever slab;

[0027] 2. Through the arrangement of the supporting ribs, when the concrete conveying in the pouring box ends and the concrete solidifies, the operator screws out the auxiliary bolt to release the limit of the auxiliary bolt on the second feeding pipe.

After the concrete in the pouring box 2 solidifies, the operator can detach the first feed pipe 3, the second feed pipe 4 and the pouring box 2. At this time, the protective sleeve 5 is located in the solidified concrete. The operator places the support bar 7 in the protective sleeve 5, conveys concrete into the protective sleeve 5 and waits for it to solidify. The support bar 7 plays a supporting role for the protective sleeve 5, improving the overall stability of the protective sleeve 5.

[0047] The implementation principle of the combined support structure of a cantilever slab in the embodiment of the present application is as follows:

[0048] The operator installs the first feed pipe 3, the protective sleeve 5 and the second feed pipe 4 onto the pouring box 2, then installs the pouring box 2 onto the wall body 1, and conveys concrete through the second feed pipe 4 and the first feed pipe 3.
