Description

Technical Field

[0001] The utility model relates to the technical field of beam supports, in particular to a cast-in-situ beam load-bearing support structure. Background Art

[0002] During the construction process of cast-in-place beams and slabs, vertical poles and formwork are required to provide structural support for the beams. The vertical poles are usually threaded rod structures with adjustable heights. In the prior art, the support of the vertical pole at the bottom of the cast-in-place slab is used as a fulcrum, and channel steels are symmetrically placed on both sides of the fulcrum. The channel steels are connected to each other with bolts to ensure stability. Multiple short vertical poles are set between the channel steels, and multiple round tubes and other supporting components are set on the top support of the vertical poles. The channel steels and vertical poles connected as a whole are used as the bottom support of the beam. However, there are still some problems in implementation:

[0003] 1. Due to issues such as manufacturing precision, on-site damage, or installation accuracy, the formwork surface at the bottom of the beam may be tilted, resulting in the circular tubes and other supporting components on the upper side of the vertical poles at the bottom of the beam not being able to fit and abut against the lower surface of the formwork. As a result, the area on the lower side of the formwork that needs support cannot be effectively supported, resulting in poor support for the beam.

[0004] At the same time, construction workers will place wooden blocks, iron blocks or rubber blocks of different shapes between the formwork and supporting components such as round tubes, so that the round tubes can effectively support the bottom of the formwork. However, since the gaps between supporting components such as round tubes and the lower surface of the formwork are inconsistent, construction workers are required to cut wooden blocks, iron blocks or rubber blocks according to the gap size, which consumes a lot of time and labor, resulting in low construction efficiency.

[0005] Therefore, there is an urgent need for a supporting structure for effectively supporting the beam body. Utility Model Content

[0047] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0048] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0049] In the description of the present invention, it should be noted that if the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the utility model product is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0050] In addition, the terms "first", "second", "third", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0051] Furthermore, the use of terms such as "horizontal," "vertical," and "overhanging" does not necessarily imply that the component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0052] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0053] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0054] It should be understood that due to problems such as manufacturing accuracy, on-site damage or installation accuracy, the surface of the formwork 31 at the bottom of the beam 3 may be tilted, resulting in the circular tube 8 and other supporting members on the upper side of the vertical pole at the bottom of the beam 3 not being able to fit and abut against the lower surface of the formwork 31, so that the area on the lower side of the formwork 31 that needs to be supported cannot be effectively supported, thereby resulting in poor support effect on the beam 3;

[0055] At the same time, installing auxiliary supporting wooden blocks and other components will consume more time, thus resulting in lower installation efficiency.

[0056] To improve the above problems, this embodiment provides a load-bearing support structure for a cast-in-place beam 3, which mainly includes two first uprights 1, two channel steels 2, and multiple second uprights 4. This structure is mainly used to effectively support the beam 3 and does not take much time to install.

[0057] like Figure 1-Figure 3 As shown, two first vertical poles 1 are arranged oppositely on both sides of the beam body 3, the two first vertical poles 141 are provided with a plate support 11, and a top support 43 is provided on the top of the first vertical pole 1, wherein the height of the first vertical pole 1 can be adjusted, thereby adjusting the height of the top support 43 and the plate support 11, and thus adapting to beam plates and beam bodies 3 of different heights.

[0058] The two channel steels 2 are arranged opposite to each other, and the notches of the two channel steels 2 are arranged away from each other, wherein the two channel steels 2 are parallel to each other, and the upper side plates and the lower side plates of the two channel steels 2 are of the same height. At the same time, the side plates in the middle of the two channel steels 2 are parallel to each other and arranged opposite to each other.

[0059] In this embodiment, Figure 1 、 Figure 7 and Figure 8 As shown, the two channel steels 2 are connected by a plurality of bolts 20, wherein the two channel steels 2 are provided with a plurality of bolt holes 24 arranged in sequence and spaced apart, and the plurality of bolts 20 connect the two channel steels 2 through the plurality of bolt holes 24, thereby making the relative positions of the two channel steels 2 stable, wherein the two ends of the two channel steels 2 are respectively arranged on the upper surfaces of the disc supports 11 of the two first vertical poles 1, thereby providing a support basis for the support of the beam body 3.

[0060] There are multiple second uprights 4, and the number of the second uprights 4 can be set according to the size and quality of the two. In this embodiment, for the convenience of description, there are two second uprights 4, and the two second uprights 4 are arranged in sequence between the two channel steels 2.

[0061] The second vertical pole 4 includes 41 and a limiting tray 42. A top support 43 is provided on the top of 41. The top support 43 is fixedly connected to 41. The top support 43 adopts a U-shaped structure, so as to facilitate the placement of the round tube 8 supporting the bottom template 31 of the beam body 3.

[0062] In this embodiment, Figure 1-Figure 3 As shown, the inner wall of the limiting tray 42 is threadedly connected to the circumferential side wall of 41 , so that the limiting tray 42 can be displaced back and forth relative to 41 along the axial direction of 41 .

[0063] Among them, the limiting tray 42 adopts a cylindrical structure. When the first vertical pole 1 is set between the two channel steels 2, a round tube 8 is set in the top support 43 to support the template 31 at the bottom of the beam. The limiting tray 42 is displaced relative to 41, thereby adjusting the height of the top support 43, and then the round tube 8 is offset from the template 31 at the bottom of the beam, thereby supporting the template 31.

[0064] When the second vertical pole 4 supports the template 31 at the bottom of the beam, the lower surface of the limiting tray 42 fits with the upper surfaces of the two channel steels 2 .

[0065] In this embodiment, a connecting plate 431 is provided on the inner wall of the bottom of the supporting bracket 43 . The connecting plate 431 is perpendicular to the inner wall of the bottom of the supporting bracket 43 .

[0066] In this embodiment, Figure 1 、 Figure 2 and Figure 10 As shown, first clamping members 5 are provided on both side walls of the connecting plate 431. The two first clamping members 5 are rotatably connected to the connecting plate 431 and are respectively facing the inner walls on both sides of the top support 43. Specifically, the first clamping member 5 includes a rotating shaft 51 and a first circular arc plate 52. The first circular arc plate 52 is adapted to the circular tube 8. One end of the rotating shaft 51 is arranged at the center of the side of the first circular arc plate 52 away from the circular tube 8. The first circular arc plate 52 is connected to the connecting plate 431 through the rotating shaft 51, so that the first circular arc plate 52 can rotate relative to the connecting plate 431.

[0067] The axial directions of the rotating shafts 51 connecting the two sides are perpendicular to the surfaces of the two sides of the connecting plate 431 , and the heights of the two rotating shafts 51 are consistent, so that the heights of the two arc plates are consistent.

[0068] In this embodiment, Figure 1 、 Figure 2 and Figure 9 As shown, second clamping members 6 are respectively provided on the inner walls of both sides of the top support 43, and one end of the two second clamping members 6 is respectively arranged opposite to the two first clamping members 5, and the second clamping members 6 are rotatably connected to the side walls of the top support 43. Specifically, the second clamping member 6 includes a second arc plate 61 and a rotating bearing 62. The rotating bearing 62 is arranged on the inner surface of the side wall of the top support 43, and a rotating sleeve 63 is provided on the outer wall of the second arc plate 61. The rotating sleeve 63 is rotatably connected to the rotating bearing 62. The first arc plate 52 and the second arc plate 61 are arranged opposite to each other, wherein the first arc plate 52 and the second arc plate 61 located on the same side of the connecting plate 431 have the same height, and the first arc plate 52 and the second arc plate 61 are adapted to the circular tube 8, so that the first arc plate 52 and the second arc plate 61 clamp the circular tube 8, thereby driving the circular tube 8 to rotate, so that the circular tube 8 is tilted to be parallel to the surface of the template 31 at the bottom of the beam, thereby effectively supporting the template 31 at the bottom of the beam.

[0069] Among them, rubber pads 10 are provided in the first arc plate 52 and the second arc plate 61, so that the friction between the circular tube 8 and the first arc plate 52 and the second arc plate 61 is relatively large, thereby stabilizing the position of the circular tube 8. At the same time, since rubber has a certain elasticity, the rubber pad 10 and the circular tube 8 are in contact with each other and fit tightly.

[0070] The axis of the rotating sleeve 63 passes through the center of the outer wall of the first arc plate 52 .

[0071] In this embodiment, Figure 1 、 Figure 2 and Figure 9 As shown, a fixing hole 611 is provided at the center of the outer wall of the second arc plate 61, and an internal thread is provided in the fixing hole 611. A tightening member 7 is provided on both side walls of the top support 43, wherein the tightening member 7 can be a connecting member such as a bolt 20 or a screw. Specifically, one end of the tightening member 7 passes through the side wall of the top support 43 and the sleeve 9, and is threadedly connected to the fixing hole 611, thereby fixing the second arc plate 61. When supporting the formwork 31 at the bottom of the beam, the first arc plate 52 and the second arc plate 61 clamp the circular tube 8, and then rotate the rod circular tube 8 to be parallel to the beam bottom formwork 31. After that, the tightening member 7 is inserted into the fixing hole 611 through the side wall of the top support 43 and connected to the second arc plate 61, thereby fixing the second arc plate 61, and then fixing the first clamping member 5, the second clamping member 6 and the circular tube 8, so that the position of the circular tube 8 is stable and the formwork 31 at the bottom of the beam is effectively supported.

[0072] In this embodiment, the circular tube 8 is clamped by the first clamping member 5 and the second clamping member 6, and the first clamping member 5 and the second clamping member 6 are respectively rotated relative to the side walls of the connecting plate 431 and the top support 43, so that the circular tube 8 rotates, and then the circular tube 8 is tilted until it is completely in contact with the surface of the template 31 at the bottom of the beam body 3, and then the first clamping member 5 is fixed by the tightening member 7, thereby fixing the circular tube 8 and the second clamping member 6, so that the circular tube 8 can effectively and stably support the template 31 at the bottom of the beam body 3.

[0073] In some embodiments, as Figure 1-Figure 3 As shown, the channel steel 2 is arranged on both sides of 41, and the middle side plate of the channel steel 2 is parallel to the two side walls of the top support 43. When 41 is respectively connected to the channel steels 2 on both sides with bolts 20, the circumferential outer wall of 41 is against the middle side plate of the channel steel 2. Specifically, 41 is provided with two first connecting holes 411, and the two channel steels 2 are provided with multiple second connecting holes 21. The heights of the multiple second connecting holes 21 are consistent and correspond one to one. The axial directions of the two first connecting holes 411 are consistent, and the axial directions of the two first connecting holes 411 are perpendicular to the two side walls of the top support 43. The two first connecting holes 411 of 41 are respectively connected with one of the multiple second connecting holes 21 of the two channel steels 2 with bolts 20, so that both sides of 41 receive the acting force, and thus the second vertical pole 4 is stably arranged between the two channel steels 2.

[0074] Specifically, which second connection hole 21 of the two channel steels 2 41 is connected to can be set according to the length of the template 31 at the bottom of the beam and the size of the area that the two second uprights 4 need to support.

[0075] In some embodiments, as Figures 1-6As shown, an arc groove 22 is provided on the upper side wall of the channel steel 2, and the arc groove 22 is adapted to the part of the plate body of the limiting tray 42 located on the vertical upper side of the channel steel 2. Specifically, an annular protrusion 421 is provided on the circumferential outer wall of the limiting tray 42, so that the construction personnel can rotate the limiting tray 42 through the annular protrusion 421, thereby making the rotation of the limiting tray 42 easier.

[0076] At the same time, the arc groove 22 is adapted to the limiting tray 42 and the annular protrusion 421, so that the plate body of the limiting tray 42 located on the vertical upper side of the channel steel 2 and the part of the annular protrusion 421 are set in the arc groove 22, thereby limiting 41, thereby preventing 41 from rotating between the two channel steels 2, thereby stabilizing the position of the second vertical pole 4.

[0077] In some embodiments, as Figure 5-Figure 9 As shown, the relative surfaces of the side plates in the middle of the two channel steels 2 are provided with multiple fixing grooves 23, and the multiple fixing grooves 23 are arranged at intervals in sequence. Specifically, the multiple fixing grooves 23 are arranged one by one in relative correspondence. A plurality of sleeves 9 are provided between the two channel steels 2. The axial direction of the sleeves 9 is perpendicular to the side plates in the middle of the channel steel 2, and the two ends of the plurality of sleeves 9 are respectively inserted into the multiple fixing grooves 23 of the two channel steels 2. When the two channel steels 2 are connected, the two ends of the plurality of sleeves 9 are respectively inserted into the multiple fixing grooves 23 of the two channel steels 2, and one end of the plurality of bolts 20 passes through the side plates of the two channel steels 2 and the plurality of sleeves 9, and is connected by nuts at one end of the bolts 20, thereby connecting the two channel steels 2. At the same time, due to the provision of the sleeves 9, the connection between the two channel steels 2 is stable and the bearing capacity is strong, which avoids the low bearing capacity of the channel steel 2 due to the long cantilever, thereby causing the channel steel 2 to be bent during use, thereby improving the service life of the channel steel 2.
