Description

Technical Field

[0001] The invention belongs to the technical field of steel support construction, and particularly relates to a steel support base and a construction method thereof. Background Art

[0002] With the acceleration of China's urbanization and the continuous maturation of construction technology, steel supports have become the main form of foundation pit support construction in recent years. By applying a pre-loaded axial force to the supports, surrounding surface settlement can be significantly reduced. Traditional support methods require pre-embedding the steel support steel plate base in the concrete crown or waist beam to serve as the steel support. At the beginning of support, the stress transfer from the embedded components can easily cause cracking in the embedded concrete. After the support is completed, the embedded steel is often left in the concrete structure without treatment, resulting in material waste. Therefore, it is extremely important to propose a steel support base structure that can meet the needs of engineering support while ensuring the safety of the surrounding structure and environmental conservation.

[0003] Therefore, the traditional embedded design of steel support base has the following shortcomings: First, the steel base cannot be reused, which will cause a large amount of material waste and environmental pollution for support projects such as deep foundation pits; second, it is easy to cause cracks in the concrete structure at the embedded position, affecting the long-term support effect. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a steel support base and a construction method thereof, which are used to solve the following technical problems: first, the steel base cannot be reused, resulting in a large amount of material waste and environmental pollution; second, it is easy to cause cracks in the concrete structure at the embedded position, affecting the long-term support effect.

[0005] On the one hand, the invention provides the following technical solutions: a steel support base, at least two embedded parts preset in a concrete layer, the embedded parts being detachably connected to a support plate, the support plate being abutted against the concrete layer, two limit seats and at least four support members being connected to the side of the support plate away from the concrete layer, all of the support members forming a limit cavity, the limit cavity being adapted to the steel support, wherein the limit seat is connected to the embedded part through a fixing part so that the limit seat is fixed on the support plate, the support members at both ends of the support plate are slidably connected to the limit seat, and the support members on both sides of the support plate are respectively connected with a limit member so that all of the support members are limited on the support plate.

[0006] Compared with the prior art, the beneficial effect of the present invention is as follows: by inserting one end of the embedded part through the support plate, and then slidingly connecting the two ends of a limit seat to two support members respectively, and then plugging a limit seat into the embedded part, and then fixing the limit seat to the lower side of the support plate through a fixing part, so that the support plate is close to the outer wall of the concrete layer.

By keeping the support plate close to the outer side of the concrete, the support plate is avoided from being embedded in the concrete. On the one hand, the support plate can be recycled, and on the other hand, it is prevented from cracking the concrete due to the support plate being embedded in the concrete. And through the plugging of the support member and the support plate, the sliding connection of the support member and the limit seat, and the plugging of the support member and the limit member, the installation and disassembly operations of the steel support base are convenient, thereby improving the disassembly and installation of the steel support.

First limiting blocks adapted to the first plug-in groove are extended from both ends of the limiting member, and multiple second limiting blocks adapted to the second plug-in groove are arranged at intervals on one side of the limiting member.

[0010] Furthermore, a first protrusion extends from one side of the first plug-in slot, and second protrusions extend from both sides of the second plug-in slot respectively. A first embedding groove adapted to the first protrusion is provided on the opposite sides of the two first limit blocks, and a second embedding groove adapted to the second protrusion is provided on both sides of the second limit block, wherein the cross-sections of the first embedding groove, the second embedding groove, the first protrusion and the second protrusion are all arc-shaped.

[0011] Furthermore, arc-shaped grooves are formed on the inner sides of all the supporting members so that the limiting cavity is a cylindrical cavity.

[0012] Furthermore, a limiting portion extends from one side of the supporting member, and at least two through holes and at least two sliding holes adapted to the limiting portion are opened on one side of the supporting plate, and the sliding hole passes through one end of the supporting plate.

[0013] Furthermore, the limiting portion includes a positioning section and a limiting section, the through hole includes a limiting hole adapted to the limiting section and a positioning hole adapted to the positioning section, the cross-sections of the limiting hole and the limiting section are rectangular, and the cross-sections of the positioning section and the positioning hole are circular.

[0014] Furthermore, one end of the through hole and the sliding hole are arranged at intervals toward the center of the support plate.

[0015] On the other hand, the present invention also provides a method for constructing a steel support base, the preparation method comprising the following steps:

[0030] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The drawings illustrate several embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] See also Figures 1 to 3 As shown, the steel support base in the first embodiment of the present invention includes at least two embedded parts 20 preset in the concrete layer 10, the embedded parts 20 are detachably connected to a support plate 30, the support plate 30 is abutted against the concrete layer 10, and the support plate 30 is connected to two limit seats 40 and at least four support members 50 on the side away from the concrete layer 10, all of the support members 50 form a limit cavity 57, and the limit cavity 57 is adapted to the steel support, wherein the limit seat 40 is connected to the embedded part 20 through a fixing part 60 so that the limit seat 40 is fixed on the support plate 30, the support members 50 at both ends of the support plate 30 are slidably connected to the limit seat 40, and the support members 50 on both sides of the support plate 30 are respectively inserted with a limit member 70 so that all of the support members 50 are limited on the support plate 30.

[0034] Specifically, when the embedded part 20 is embedded, one end of the embedded part 20 extends out of the concrete layer 10, and the extended portion of the embedded part 20 is provided with threads. The upper and lower sides of the support plate 30 are respectively provided with first mounting holes 33 corresponding to the embedded part 20. The stopper 40 is provided with second mounting holes 41. The extended portion of the embedded part 20 passes through the first mounting holes 33 and the second mounting holes 41 in sequence. The fixing member 60 is then threadedly connected to the embedded part 20, so that the support plate 30 is pressed against one side of the concrete layer 10 and the stopper 40 is pressed and installed on one side of the support plate 30. The two stoppers 40 are respectively provided with second mounting holes 41 at both ends, and the support plate 30 is also provided with first mounting holes 33 at four positions. In a specific implementation, each of the two stoppers 40 has two second mounting holes 41, and the support plate 30 has four first mounting holes 33. The number of embedded parts 20 is four.

[0035] Furthermore, an arc-shaped groove 58 is formed on the inner side of all the supporting members 50 so that the limiting cavity 57 is a cylindrical cavity.

[0036] See also Figure 4 As shown, one end of each of the through-holes 31 and the sliding hole 32 is spaced apart toward the center of the support plate 30. It is worth noting that the multiple through-holes 31 are spaced apart in the center direction of the support plate 30, and the multiple sliding holes 32 are spaced apart from each other in a groove, with their lengths increasing from top to bottom, so that one end of each of the sliding holes 32 (the end closest to the center of the support plate 30) forms a straight line toward the center of the support plate 30. This allows the support member 50 connected to the through-holes 31 and the sliding hole 32 to move closer to the support plate 30, thereby adjusting the size of the limiting cavity 57 formed by the support member 50 to accommodate steel supports of different sizes. It is understandable that one end of each of the sliding holes 32 (the end closest to the center of the support plate 30) is disposed on a diagonal line of the support plate 30, and the through-holes 31 are also spaced apart on the diagonal line of the support plate 30.

[0037] Furthermore, all of the support members 50 are distributed along the four sides of a rectangle, with a support member 50 positioned at each of the intersections of the rectangle. The support members 50 at the four corners are slidably connected to the limit seats 40 and plugged into the limit members 70. By distributing all of the support members 50 along the four sides of the rectangle, the support members 50 can limit the steel support within the limit cavity 57 in multiple directions. Furthermore, by providing the support members 50 at the four corners and connecting them to the limit members 70 and the limit seats 40, the strength of all of the support members 50 is enhanced, thereby further strengthening the steel support within the limit cavity 57.

[0038] See also Figure 5 and Figure 6 As shown, in some optional embodiments, the number of the supporting members 50 may be four or six.

[0039] When there are four support members 50 , the four support members 50 are respectively arranged at the four corner points of a rectangle, and the support member 50 includes a first base portion 51 , a first sliding portion 52 and a first plug-in portion 53 ;

[0040] When there are six support members 50, four support members 50 are arranged at the four corners of the rectangle, and the other two are arranged on the left and right opposite sides of the rectangle. Similarly, the support members 50 arranged at the four corners include a first base 51, a first sliding portion 52, and a first plug-in portion 53, and the support members 50 arranged on the left and right sides of the rectangle include a second base 54 and a second plug-in portion 55.

[0041] Among them, a sliding groove 521 is respectively opened on one side of the first sliding part 52, and the sliding groove 521 passes through the two ends of the first sliding part 52, and a first plug-in groove 531 and a second plug-in groove 551 are respectively opened on one side of the first plug-in part 53 and the second plug-in part 55, and the first plug-in groove 531 and the second plug-in groove 551 pass through the two ends of the first plug-in part 53 and the second plug-in part 55 respectively, and a first limiting block 71 adapted to the first plug-in groove 531 is extended from both ends of the limiting member 70, and a plurality of second limiting blocks 72 adapted to the second plug-in groove 551 are arranged at intervals on one side of the limiting member 70.

[0042] It is worth noting that by inserting the second limiting block 72 into the second insertion slot 551, the left and right support members 50 are limited together with the limiting member 70, so that the left and right support members 50 can limit the two sides of the steel support, thereby further improving the stability of the steel support. It is understandable that the upper and lower fixing members 60 of the support plate 30 are fixed with limiting seats 40, and the limiting seats 40 can limit the support members 50 in the upper and lower directions. Therefore, the limiting effect of the upper and lower sides of the support plate 30 is better than the limiting effect of the left and right sides of the support plate 30. Therefore, when the number of the support members 50 is six, two of the support members 50 are arranged on the left and right sides of the support plate 30.

[0043] Furthermore, a first protrusion 532 extends from one side of the first insertion slot 531, and second protrusions 552 extend from both sides of the second insertion slot 551. Opposing sides of the two first limiting blocks 71 each have a first insertion slot 711 that mates with the first protrusion 532, and opposing sides of the second limiting block 72 each have a second insertion slot 721 that mates with the second protrusion 552. The first insertion slot 711, the second insertion slot 721, the first protrusion 532, and the second protrusion 552 all have arc-shaped cross-sections. It is worth noting that by inserting the first protrusion 532 into the first insertion slot 711 and inserting the second protrusion 552 into the second insertion slot 721, the limiting member 70 and the support member 50 are stably secured together. Furthermore, by having the first insertion slots 711 on opposing sides of the two first limiting blocks 71 and the second insertion slots 721 on both sides of the second limiting block 72, the stability of the limiting member 70 and the support member 50 is further improved.

[0044] Furthermore, a contoured groove 34 adapted to the limiting member 70 is opened on the side of the support plate 30 away from the concrete layer 10. When the first limiting block 71 of the limiting member 70 is inserted into the first plug-in groove 531, the limiting member 70 is simultaneously inserted into the contoured groove 34, so that the limiting member 70 is stably limited on the support plate 30, and further the limiting member 70 can stably limit the supporting member 50 on the support plate 30.

[0045] See also Figure 7 As shown, a stopper 56 extends from one side of each of the support members 50. One side of the support plate 30 is provided with at least two through-holes 31 and at least two sliding holes 32 that match the stopper 56. The sliding holes 32 extend through one end of the support plate 30. A slide rail 42 is fixed to one side of the stop seat 40. It is understood that when the stopper 56 enters the sliding hole 32, it slides into the sliding hole 32 through one side of the sliding hole 32, and the support member 50 is slidably connected to the slide rail 42 on the stop seat 40.

[0046] The limiting portion 56 includes a positioning section 561 and a limiting section 562. The through hole 31 includes a limiting hole 312 that matches the limiting section 562 and a positioning hole 311 that matches the positioning section 561. The limiting hole 312 and the limiting section 562 have rectangular cross-sections, while the positioning section 561 and the positioning hole have circular cross-sections. The rectangular limiting hole 312 and the limiting section 562 ensure a more stable position of the limiting portion 56 within the through hole 31. The positioning section 561 and the positioning hole 311 help position the limiting portion 56, thereby positioning the support member 50. It is understood that the dimensions of the rectangular cross-section are larger than the dimensions of the circular cross-section.

[0047] Example 2

[0048] See also Figure 8 , which shows a method for preparing a flip-chip Micro-LED chip according to a second embodiment of the present invention, the method comprises the following steps:

[0049] S101: Provide a foundation pit and a support plate 30, with multiple through holes 31 and two sliding holes 32 opened on the support plate 30, construct concrete layers 10 on two opposite walls of the foundation pit, and pre-embed multiple embedded parts 20 in the concrete layer 10, insert the support plate 30 into all the embedded parts 20, and make the support plate 30 close to the concrete layer 10.

[0050] During the specific implementation, a foundation pit is first excavated, and a concrete beam (concrete layer 10) is cast on the foundation pit. At the same time, the embedded part 20 is embedded in the cast concrete beam, and one end of the embedded part 20 extends out of the concrete layer 10. Four first mounting holes 33 and multiple through holes 31 are opened on the support plate 30. After the concrete layer 10 solidifies, one end of the embedded part 20 is inserted into the first mounting hole 33 on the support plate 30, and the support plate 30 is placed against the side wall of the concrete layer 10.

[0051] S102: Providing a plurality of support members 50, at least two of the support members 50 being slidably connected to a limiting seat 40, inserting the limiting seat 40 into the embedded part 20 at one end of the support plate 30, and inserting the limiting portion 56 of the support member 50 into the through hole 31, and fixing a fixing member 60 on the embedded part 20 to fix the limiting seat 40 and the support members 50 slidably connected thereto on the support plate 30;

[0052] In a specific implementation, four support members 50, two limit seats 40 and four fixing members 60 are provided. A limit portion 56 is extended from one side of the plurality of support members 50. A slide groove 521 and a first plug-in groove 531 are provided on the support member 50. A second mounting hole 41 is provided at each end of the limit seat 40. A slide rail 42 is fixed on one side of the limit seat 40. The slide grooves 521 of the two support members 50 are slidably connected to the slide rail 42 to connect the two support members 50 with a limit seat 40, and then The second mounting hole 41 is aligned with the two embedded parts 20 on the lower side of the support plate 30, so that the two embedded parts 20 are respectively inserted into the two second mounting holes 41, and then the two fixing parts 60 are respectively connected to the two embedded parts 20 by screws, so that the support plate 30 is close to one side of the concrete layer 10, and a limit seat 40 is squeezed and installed on the support plate 30. At this time, because the limiting part 56 of the support member 50 is inserted into the through hole 31, the slide groove 521 is slidably connected to the slide rail 42, so that the two support members 50 are limited to the lower side of the support plate 30.

[0053] S103: placing a steel support on the support member fixed to the support plate 30, then inserting a limit seat 40 on the embedded part 20 at the other end of the support plate 30, fixing a fixing part 60 on the embedded part 20 to limit the limit seat 40 on the support plate 30, and then slidingly connecting at least two support members 50 on the limit seat 40;

[0054] During the specific implementation, one end of the steel support is placed on the two supporting members 50 fixed on the support plate 30, and then the two second mounting holes 41 on the other limiting seat 40 are aligned with the two embedded parts 20 on the upper side of the support plate 30, and then the embedded parts 20 are inserted into the second mounting holes 41, and then the remaining two fixing members 60 are threadedly connected to the embedded parts 20 on the upper side, so that the other limiting seat 40 is squeezed and installed on the support plate 30, and at the same time, the support plate is also close to the side wall of the concrete layer 10, and then the slide groove 521 of the remaining two supporting members 50 is slidably connected to the slide rail 42, and at the same time, its limiting part 56 slides into one end of the sliding hole 32, so that the supporting members 50 on the upper and lower sides of the support plate 30 are in the same straight line, and similarly, the four supporting members 50 are at the four corner points of the rectangle.

[0055] S104 : Insert a limiting member 70 into each of the supporting members 50 on both sides of the support plate 30 to limit the plurality of supporting members 50 together.

[0056] In a specific implementation, two limiting members 70 are provided, and first limiting blocks 71 extend from both ends of the limiting members 70 respectively. The first limiting blocks 71 at both ends of a limiting member 70 are inserted into the first plug-in grooves 531 of the two supporting members 50 on the left side of the support plate 30, so that the two supporting members 50 on the left are limited together. Similarly, the first limiting blocks 71 at both ends of a limiting member 70 are inserted into the first plug-in grooves 531 of the two supporting members 50 on the right side of the support plate 30. At this time, the four supporting members 50 are limited on the support plate 30, and the steel support is limited between the four supporting members 50, thereby completing the installation of the steel support.

[0057] Furthermore, in step S104, a contoured groove 34 adapted to the limiting member 70 is opened on the side of the support plate 30 away from the concrete layer 10, and when the first limiting block 71 provided by the limiting member 70 is inserted into the first plug-in groove 531, the limiting member 70 is simultaneously inserted into the contoured groove 34, so that the limiting member 70 is stably limited on the support plate 30, and further the limiting member 70 can stably limit the supporting member 50 on the support plate 30.

[0058] In summary, the steel support base and its construction method in the above-mentioned embodiment of the present invention are as follows: one end of the embedded part 20 is inserted through the support plate 30, and then the two ends of a limit seat 40 are slidably connected to the two supporting members 50, and then a limit seat 40 is plugged into the embedded part 20, and then the limit seat 40 is fixed to the lower side of the support plate 30 by the fixing member 60, so that the support plate 30 is close to the outer wall of the concrete layer 10. At this time, the two supporting members 50 are also fixed to the lower side of the support plate 30, and then the steel support is placed on the two supporting members 50, and then a limit seat 40 is inserted on the side of the support plate, and then the two supporting members 50 are slidably connected on the limit seat 40, and then the limit members 70 are inserted into the supporting members 50 on both sides, thereby completing the installation of the steel support. By having the support plate 30 close to the outer side of the concrete, the support plate is prevented from being embedded in the concrete. On the one hand, the support plate can be recycled, and on the other hand, the concrete is prevented from cracking due to the support plate being embedded in the concrete. And through the plugging of the support member 50 and the support plate 30, the sliding connection of the support member 50 and the limit seat 40, and the plugging of the support member 50 and the limit member 70, the disassembly and installation operations of the steel support base are facilitated, thereby improving the disassembly and installation of the steel support.
