Description

Technical Field

[0001] The present invention relates to the field of construction technology of steel supports, and specifically to a steel support base and its construction method.

Background Art

[0002] With the accelerating progress of urbanization in China and the continuous maturity of construction technology, in recent years, steel supports have become the main working form for the support and protection construction of foundation pits. By adding pre-support axial force, the settlement of the surrounding ground surface can be significantly reduced. In the conventional erection support method, in order to play the role of support by erection steel, it is necessary to pre-embed a steel plate, which is a steel support, in the top end or middle beam of concrete. When the support and protection start, due to the influence of stress transmission of the embedded member, the concrete at the embedded location is likely to crack. And when the support and protection end, the embedded steel remains in the concrete structure without being processed, often causing waste of materials. Therefore, it is extremely important to propose a steel support base structure that can meet the support and protection needs of the project while also meeting the requirements of the safety of the enclosure structure and energy conservation and environmental protection.

[0003] Therefore, the conventional embedded design of the steel support base has the following disadvantages. First, since the steel base cannot be reused, it causes a large amount of material waste and environmental pollution in support and protection projects such as deep foundation pits. Second, cracks are likely to occur in the concrete structure at the embedded location, affecting the long-term support and protection effect.

Some embodiments of the present invention are shown in the accompanying drawings. However, the present invention can be implemented in various forms and is not limited to the embodiments described in this specification. Rather, these embodiments are provided to make the disclosure of the present invention more complete.

[0019] In addition, when an element is described as being "fixedly provided" to another element, the element may be directly disposed on the other element or there may be intervening elements. When an element is considered to be "connected" to another element, it may be directly connected to the other element or intervening elements may also be present at the same time. Terms such as "vertical", "horizontal", "left", "right", etc. used in this specification and similar expressions are for the purpose of explanation only.

[0020] All technical terms and scientific terms used in this specification have the same meaning as those generally understood by those skilled in the technical field of the present invention, unless otherwise defined. The terms used in this specification are for the purpose of describing specific embodiments only and do not limit the present invention. The term "and / or" used in this specification includes any combination of one or more of the related listed items.

[0021] As shown in FIGS. 1 to 3, the steel support base in the first embodiment of the present invention includes at least two embedded members 20 provided in advance in the concrete layer 10. One support plate 30 is detachably connected to the embedded member 20. The support plate 30 is disposed in close contact with the concrete layer 10. On one side of the support plate 30 away from the concrete layer 10, two limiting seats 40 and at least four erection support members 50 are connected. All the erection support members 50 form one limiting cavity 57. The limiting cavity 57 is compatible with the steel support. The limiting seat 40 is connected to the embedded member 20 through a fixing member 60 so that the limiting seat 40 is fixedly provided on the support plate 30. The erection support members 50 at both ends of the support plate 30 are slidably connected to the limiting seat 40. One limiting member 70 is inserted and mounted on each of the erection support members 50 on both sides of the support plate 30, and all the erection support members 50 are restricted on the support plate 30.

[0022] Specifically, when the embedding tool 20 is embedded, one end of the embedded member 20 extends out of the concrete layer 10, and a thread is provided on the extended portion of the embedded member 20. First mounting holes 33 corresponding to the embedded members 20 one by one are respectively opened on both the upper and lower sides of the support plate 30. A second mounting hole 41 is opened in the limiting seat 40. The extended portion of the embedded member 20 passes through the first mounting hole 33 and the second mounting hole 41 in sequence, and further by screwing the fixing member 60 to the embedded member 20, the support plate 30 is pressed against one side of the concrete layer 10, and the limiting seat 40 is pressed against one side of the support plate 30 and mounted. Here, second mounting holes 41 are provided at both ends of the two limiting seats 40, and first mounting holes 33 are also provided at four locations of the support plate 30 respectively. In a specific embodiment, two second mounting holes 41 are provided in each of the two limiting seats 40, four first mounting holes 33 are opened in the support plate 30, and the number of the embedded members 20 is four.

[0023] Furthermore, all of the erection support members 50 have an arc-shaped groove 58 on their inside so that the restricting cavity 57 becomes a cylindrical cavity.

[0024] As shown in Figure 4, one end of each of the through-holes 31 and the sliding holes 32 are spaced apart toward the center of the support plate 30. Further explanation is needed because the multiple through-holes 31 are spaced apart toward the center of the support plate 30, and the multiple sliding holes 32 are spaced apart so that their length increases from top to bottom. As a result, one end of each sliding hole 32 (the end closest to the center of the support plate 30) is formed in a straight line toward the center of the support plate 30, allowing the erection support member 50 connected to the through-holes 31 and the sliding holes 32 to be brought closer to the support plate 30, and the size of the limiting cavity 57 surrounded by the erection support member 50 can be adjusted to apply steel supports of various dimensions. It will be understood that one end of each sliding hole 32 (the end closest to the center of the support plate 30) is provided on the diagonal of the support plate 30, and the through-holes 31 are also spaced apart on the diagonal of the support plate 30.

[0025] Furthermore, all of the erection support members 50 are arranged along the four sides of the rectangle, and one erection support member 50 is provided at each intersection of the rectangle. The erection support members 50 at each of the four corners are slidably connected to the restriction seat 40 and inserted into the restriction member 70. By arranging all of the erection support members 50 along the four sides of the rectangle, all of the erection support members 50 can restrict the steel support in the restriction cavity 57 from multiple directions. In addition, by providing the erection support members 50 at the four corners, and by connecting the erection support members 50 at each of the four corners to the restriction member 70 and the restriction seat 40, the robustness between all of the erection support members 50 is improved, making the steel support in the restriction cavity 57 more robust.

[0026] As shown in Figures 5 and 6, in some optional embodiments, the number of the erection support members 50 may be four or six.

[0027] When there are four of the erection support members 50, each of the four erection support members 50 is provided at one of the four corners of a rectangular shape, and the erection support member 50 includes a first base portion 51, a first sliding connection portion 52, and a first insertion mounting portion 53.

[0028] When there are six of the erection support members 50, four of them are provided at the four corners of the rectangular shape, and the remaining two are provided at the opposite left and right sides of the rectangular shape. Similarly, the erection support members 50 provided at the four corners include a first base 51, a first sliding connection 52, and a first insertion mounting portion 53, while the erection support members 50 provided at the left and right sides of the rectangular shape include a second base and a second insertion mounting portion.

[0029] Here, a sliding groove 521 is provided on one side of the first sliding connection portion 52, and the sliding groove 521 penetrates both ends of the first sliding connection portion. A first insertion mounting groove 531 and a second insertion mounting groove 551 are provided on one side of the first insertion mounting portion 53 and the second insertion mounting portion 55, respectively, and the first insertion mounting groove 531 and the second insertion mounting groove 551 penetrate both ends of the first insertion mounting portion 53 and the second insertion mounting portion 55, respectively. A first restricting block 71 that fits the first insertion mounting groove 531 extends from both ends of the restricting member 70, and a plurality of second restricting blocks 72 that fit the second insertion mounting groove 551 are arranged at intervals on one side of the restricting member 40.

[0030] It is necessary to explain that when the second restriction block 72 is inserted and mounted in the second insertion groove 551, the erection support members 50 on both the left and right sides are restricted together with the restriction member 70, so that the erection support members 50 on both the left and right sides can restrict both sides of the steel support, further improving the stability of the steel support. Restriction seats 40 that can restrict the erection support members 50 in the vertical direction are fixedly provided on the fixing members 60 located on both the upper and lower sides of the support plate 30, and it will be understood that the vertical restriction effect of the support plate 30 is superior to the horizontal restriction effect of the support plate 30. For this reason, when there are six erection support members, two of them are provided on the left and right sides of the support plate 30, respectively.

[0031] Furthermore, a first projection 532 extends from one side of the first insertion groove 531, and second projections 552 extend from both sides of the second insertion groove 551. A first insertion groove 711, which fits the first projection 532, is provided on each of the opposing sides of the two first restricting blocks 71, and a second insertion groove 721, which fits the second projection 552, is provided on each side of the second restricting block 72. The cross-sections of the first insertion groove 711, the second insertion groove 721, the first projection 532, and the second projection 552 are all arc-shaped. Additional explanation is needed because the first projection 532 is inserted into the first insertion groove 711 and the second projection 552 is inserted into the second insertion groove 721, thereby stably restricting the restricting member 70 and the erection support member 50. Furthermore, the stability of the restricting member 70 and the erection support member 50 is further improved by providing the first insertion grooves 711 in the two first restricting blocks 71 on opposite sides, and by providing the second insertion grooves 721 on both sides of the second restricting block 72.

[0032] Furthermore, a molding groove 34 that fits the restricting member 70 is provided on the side of the support plate 30 away from the concrete layer 10. When the first restricting block 71 of the restricting member 70 is inserted into the first insertion groove 531, the restricting member 70 is simultaneously inserted into the molding groove 34, thereby stably restricting the restricting member 70 on the support plate 30, and further enabling the restricting member 70 to stably restrict the erection support member 50 on the support plate 30.

[0033] As shown in Figure 7, a limiting portion 56 extends from one side of each of the erection support members 50, and at least two through holes 31 and at least two sliding holes 32 are provided on one side of the support plate 30 to fit the limiting portion 56, with the sliding holes 32 passing through one end of the support plate 30. A slide rail 42 is fixedly provided on one side of the limiting seat 40, and it will be understood that when the limiting portion 56 enters the sliding hole 32, the limiting portion 56 slides into the sliding hole 32 through one side of the sliding hole 32, and at the same time the erection support member 50 is slidably connected to the slide rail 42 on the limiting seat 40.

[0034] Here, the limiting portion 56 includes a positioning portion 561 and a limiting portion 562, and the through hole 31 includes a limiting hole 312 that fits the limiting portion 562 and a positioning hole 311 that fits the positioning portion 561, with the cross-sections of the limiting hole 312 and the limiting portion 562 being rectangular, and the cross-sections of the positioning portion 561 and the positioning hole being circular. By setting the limiting hole 312 and the limiting portion 562 to be rectangular, the limiting portion 56 can be more stably restricted within the through hole 31. By providing the positioning portion 561 and the positioning hole 311, a positioning effect is exerted on the limiting portion 56, and they play a positioning role on the erection support member 50. It will be understood that the dimensions of the rectangular cross-section are larger than the dimensions of the circular cross-section.

[0035] Second Embodiment Referring to Figure 8, a method for constructing a steel support base according to a second embodiment of the present invention is shown, the method comprising the following steps: S101: One foundation pit and one support plate 30 are prepared, and the support plate 30 has multiple through holes 31 and two sliding holes 32. A concrete layer 10 is constructed on two opposing ground walls of the foundation pit, and multiple embedded members 20 are pre-embedded in the concrete layer 10. The support plate 30 is inserted and attached to all of the embedded members 20, and the support plate 30 is made to be in close contact with the concrete layer 10.

[0036] In a specific embodiment, first a foundation pit is excavated, and a concrete beam (concrete layer 10) is poured onto the foundation pit. At the same time, the embedding member 20 is pre-embedded within the concrete beam, and one end of the embedding member 20 is extended from the outside of the concrete layer 10. The support plate 30 has four first mounting holes 33 and a plurality of through holes 31. After the concrete layer 10 has hardened, one end of the embedding member 20 is inserted into the first mounting hole 33 of the support plate 30, and the support plate 30 is brought into close contact with the side wall of the concrete layer 10.

[0037] S102: Multiple erection support members 50 are prepared, and at least two of the erection support members 50 are slidably connected to one restriction seat 40. The restriction seat 40 is inserted into the embedded member 20 at one end of the support plate 30, the restriction portion 56 of the erection support member 50 is inserted into the through hole 31, and a fixing member 60 is fixed to the embedded member 20, thereby fixing the restriction seat 40 and the erection support member 50 slidably connected thereto onto the support plate 30.

[0038] In a specific embodiment, four erection support members 50, two restriction seats 40, and four fixing members 60 are provided. A restriction portion 56 extends from one side of each of the multiple erection support members 50, and a sliding groove 521 and a first insertion mounting groove 531 are provided in the erection support members 50. Second mounting holes 41 are provided at both ends of the restriction seats 40, and a slide rail 42 is fixedly provided on one side of the restriction seat 40. The sliding grooves 521 of two of the erection support members 50 are slidably connected to the slide rail 42, thereby connecting the two erection support members 50 to one restriction seat 40. Subsequently, the second mounting holes 41 are aligned with the two embedded portions 20 on the lower side of the support plate 30, and the two embedded portions 20 are inserted into the two second mounting holes 41, respectively. Next, the support plate 30 is brought into close contact with one side of the concrete layer 10 by screwing the two fixing members 60 to the two embedded parts 20, and one restricting seat 40 is pressed against and attached to the support plate 30. At this time, since the restricting part 56 of the erection support member 50 is inserted into the through hole 31, the sliding groove 521 is slidably connected to the slide rail 42, thereby restricting the two erection support members 50 to the lower side of the support plate 30.

[0039] S103: A steel support is positioned on the erection support member fixed to the support plate 30, and one restricting seat 40 is inserted into the embedded member 20 at the other end of the support plate 30. A fixing member 60 is fixedly provided on the embedded member 20, so that the restricting seat 40 is restricted by the support plate 30, and at least two erection support members 50 are slidably connected to the restricting seat 40.

[0040] In a specific embodiment, one end of the steel support is placed on two erection support members 50 fixed to the support plate 30, and then two second mounting holes 41 on the other limiting seat 40 are aligned with the two upper embedding members 20 of the support plate 30. Next, the embedding members 20 are inserted into the second mounting holes 41, and then the remaining two fixing members 60 are screw-connected to the upper embedding member 20, pressing the other limiting seat 40 against the support plate 30 and attaching it, while also making the support plate tightly attached to the side wall of the concrete layer 10. Next, the sliding grooves 521 of the remaining two erection support members 50 are slidably connected to the slide rail 42, and their limiting portions 56 are slid into one end of the sliding hole 32. This causes the erection support members 50 on both the upper and lower sides of the support plate 30 to be located on the same straight line, and similarly, the four erection support members 50 are located on the four corners of a rectangle.

[0041] S104: A limiting member 70 is inserted and attached to each of the erection support members 50 on both sides of the support plate 30, thereby restricting the multiple erection support members 50 from one another.

[0042] In a specific embodiment, two restricting members 70 are provided. First restricting blocks 71 extend from both ends of each restricting member 70, and the first restricting blocks 71 at both ends of one restricting member 70 are inserted into the first insertion grooves 531 of the two erection support members 50 on the left side of the support plate 30, thereby restricting both of the left-side erection support members 50. Similarly, the first restricting blocks 71 at both ends of one restricting member 70 are inserted into the first insertion grooves 531 of the two erection support members 50 on the right side of the support plate 30. At this time, the four erection support members 50 are restricted on the support plate 30, and the steel support is restricted between the four support members 50, thereby completing the installation of the steel support.

[0043] Furthermore, in step S104, a molding groove 34 is formed on the side of the support plate 30 away from the concrete layer 10, and when the first restricting block 71 of the restricting member 70 is inserted into the first insertion groove 531, the restricting member 70 is simultaneously inserted into the molding groove 34, thereby stably restricting the restricting member 70 on the support plate 30, and furthermore, the restricting member 70 can stably restrict the erection support member 50 on the support plate 30.

[0044] As described above, according to the steel support base and its construction method in the above embodiment of the present invention, one end of the embedded member 20 is inserted through the support plate 30, then two erection support members 50 are slidably connected to both ends of one restriction seat 40, and subsequently one restriction seat 40 is inserted and attached to the embedded member 20, and then one restriction seat 40 is fixed to the lower side of the support plate 30 via a fixing member 60, thereby bringing the support plate 30 into close contact with the outer wall of the concrete layer 10. At this time, the two erection support members 50 are also fixed to the lower side of the support plate 30. Next, the steel support is placed on the two erection support members 50, one restriction seat 40 is inserted and attached to the side of the support plate, the two erection support members 50 are slidably connected to this restriction seat 40, and then restriction members 70 are inserted and attached to the erection support members 50 on both sides, completing the installation of the steel support. By making the support plate 30 tightly attached to the outside of the concrete, the support plate is prevented from being embedded in the concrete. This allows for the reuse of the support plate while preventing cracking of the concrete caused by the support plate being embedded in the concrete. Furthermore, the insertion and attachment of the erection support member 50 and the support plate 30, the slidable connection of the erection support member 50 and the restriction seat 40, and the insertion and attachment of the erection support member 50 and the restriction member 70 make it easier to remove the steel support base and improve the ease of removal of the steel support.
