Description

Technical Field

[0001] The invention relates to the technical field of post-cast strip support, in particular to an adjustable and recyclable post-cast strip support device. Background Art

[0002] With the rapid development of underground space, building basements are becoming deeper and larger. To adapt to the current situation and prevent harmful cracks that may occur in reinforced concrete structures due to uneven shrinkage or settlement, post-cast strips are left at the corresponding positions of the foundation slab, walls, and beams.

[0003] During basement construction, in order to ensure the safety of foundation pit support, the bottom plate needs to be used as a horizontal support structure to evenly transfer the horizontal load. However, due to the presence of the post-cast strip, the bottom plate cannot form a whole, resulting in uneven transfer of horizontal loads. Usually, H-shaped steel is often buried in the post-cast strip of the bottom plate in advance, and the H-shaped steel is used as a force-transmitting member to transfer the horizontal load. However, during construction, a water-stop steel plate is installed in the middle of the post-cast strip, and it is blocked by the bottom plate steel bars, making it difficult to bury the H-shaped steel and making it impossible to remove the H-shaped steel.

[0004] Most existing support structures use telescopic parts for support, which leads to insufficient support for the side walls of the bottom slab concrete. In addition, the structure is loose, the installation is cumbersome, the structure is unstable, and the disassembly and installation require a lot of manpower, which is inefficient.

[0032] See also Figures 1 to 8 , the present invention provides a technical solution:

[0033] Example 1:

[0034] The invention discloses an adjustable and recyclable post-casting strip supporting device, which comprises a post-casting strip component and a supporting component.

[0035] The post-cast strip assembly includes a pair of bilaterally symmetrical bottom plate concrete 1 , a pad 2 is provided at the lower end of the bottom plate concrete 1 , and a pair of water-stop steel plates 3 are pre-embedded and installed transversely on the bottom plate concrete 1 .

[0036] The supporting assembly includes a blocking side plate 4, a supporting frame and a lifting assembly. The blocking side plate 4 is attached to the side of the bottom plate concrete 1. A connecting sleeve 5 is fixedly installed on the blocking side plate 4. A slider 19 is slidably installed in the connecting sleeve 5. A second spring 18 is provided between one side of the slider 19 and the inner wall of the connecting sleeve 5. The other side of the slider 19 is provided with a rotating rod 17 rotatably connected to the lifting assembly.

[0037] By arranging the slider 19 to cooperate with the connecting sleeve 5, the rotating rod 17 is used to achieve an inclined connection with the lifting assembly.

[0038] The support frame includes a pair of side frames 7 fixed on the backing plate 2 and distributed front and back, and an upper fixing block 6 and a lower fixing block 8 fixed in the middle of the side frames 7. A screw rod 12 is rotatably installed on the vertical thread of the upper fixing block 6.

[0039] The fixed block is fixedly supported by the support frame, and the lifting assembly is driven downward by the threaded rotation of the screw 12. Due to the inclined connection, the rotating rod 17 laterally squeezes the slider 19 to achieve lateral squeezing support for the blocking side plate 4.

[0040] The lifting assembly includes a lifting block 9 and a column 11. The lower end of the screw 12 is rotated and pressed onto the lifting block 9 through a bearing 13. The column 11 is vertically fixed to the lower end of the lifting block 9. The lower end of the column 11 slides through the lower fixed block 8, and a first spring 10 is pressed between the lower end of the lifting block 9 and the lower fixed block 8.

[0041] By setting the insertion column 11 and cooperating with the lower fixed block 8, the lifting and lowering of the lifting block 9 is limited. The first time spring 10 is used to facilitate automatic reset during disassembly. The second spring 18 is set to adjust the extrusion force, so as to adapt to the extrusion adjustment of the side wall of the bottom plate concrete 1 with different roughness. The connection of multiple groups of blocking side panels 4 is achieved through the support frame, and unified installation and disassembly are achieved, which greatly improves the efficiency of installation support. At the same time, the lifting assembly is used to achieve synchronous lateral extrusion and fixation of multiple groups of blocking side panels 4, which greatly reduces the number of installations. At the same time, the thread of the screw 12 is screwed in to fix the height, so as to achieve the purpose of fixing the extrusion lateral force and maintain stable extrusion support.

[0042] Example 2:

[0043] On the basis of embodiment 1, in order to realize the position limitation of the lateral extrusion of the slider 19, there is also a

[0044] The outer end of the connecting sleeve 5 is provided with an open groove-shaped plug-in cavity 28, one end of the slider 19 is plugged into the inner side of the plug-in cavity 28, and the other end of the slider 19 is plugged into the outer side of the plug-in cavity 28. A baffle is provided at the outer end of the plug-in cavity 28, and a pair of side strips distributed in a circular array are provided on the side walls of the plug column 11 and the slider 19. The socket on the lower fixed block 8 and the inner wall of the plug-in cavity 28 are provided with limiting grooves that cooperate with the side strips.

[0045] The position of the slider 19 is limited by setting the plug-in inner cavity 28, and a section of the plug-in inner cavity 28 is set to be open, so as to facilitate the rotation adjustment of the rotating rod 17. The limiting groove and the side bar are used to prevent the slider 19 and the plug column 11 from rotating, thereby providing stable lifting and driving extrusion.

[0046] Example 3:

[0047] On the basis of Example 2, in order to connect the lifting block 9 with multiple groups of blocking side panels 4, a pair of guide rails 15 are symmetrically installed on both sides of the lifting block 9, and a T-shaped slide groove 26 is provided on the guide rail 15. A plug plate 16 is provided in the slide groove 26, and a T-shaped plug strip 29 is provided on one side of the plug plate 16 to cooperate with the slide groove 26.

[0048] Through the cooperation between the sliding groove 26 and the T-shaped inserting strip 29 , the positions of the inserting plate 16 and the blocking side plate 4 are adapted to each other.

[0049] A pair of connecting ear seats 14 are provided on the side walls of the lifting block 9, and a clamping ear seat 27 is provided on the side wall of the guide rail 15. The clamping ear seat 27 is sleeved and clamped on the front and rear side walls of the connecting ear seat 14, and the clamping ear seat 27 and the connecting ear seat 14 are fixedly connected by a pin.

[0050] By connecting the connecting ear seat 14 with the clamping ear seat 27 , the guide rail 15 is connected to the lifting block 9 and the insert plate 16 , thereby achieving unified driving of the lifting block 9 on multiple groups of blocking side plates 4 .

[0051] Example 4:

A mounting seat 23 is provided on the inner side of a pair of symmetrical blocking side plates 4 on the left and right. A through hole is provided on the mounting seat 23, and a connecting roller 22 is inserted into the through hole. The inner diameter of the through hole is larger than the outer diameter of the connecting roller 22. The ends of the pair of connecting rollers 22 distributed on the left and right are respectively sleeved and installed with a first clamping strip 21 and a second clamping strip 24. A clamping groove is provided on the first clamping strip 21, and a clamping block is provided on the second clamping strip 24. The clamping groove and the clamping block are matched and plugged in. The lower end screw of the side frame 7 is fastened to the pad 2, and the side frame 7 is fixedly connected to the upper fixed block 6 and the lower fixed block 8 by a telescopic connecting rod 25.

[0053] The rotation of the rotating rod 17 is achieved by providing a hinge seat 20, so that when storing and disassembling, the lateral extrusion force of the blocking side panel 4 is reduced under the reset elastic force of the second spring 18, and the rotating rod 17 is relatively rotated for storage, so that the left and right adjacent blocking side panels 4 rotate relative to each other, and the connection of multiple groups of blocking side panels 4 is achieved by providing a connecting fork stick 22, and then during relative rotation, the first clamping strip 21 and the second clamping strip 24 are clamped and fixed to each other, so as to achieve unified and orderly storage of multiple groups of blocking side panels 4 on both sides, which greatly improves the convenience of disassembly, and the telescopic connecting rod 25 is provided to make the length of the support frame adapt to the installation of post-casting strips of different lengths.
