[0042] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0043] Embodiment 1

[0044] The present embodiment relates to a corbel 1, which is used to support a construction support during the construction of a cap beam.

[0045] In terms of overall structure, Figure 1 , Figure 2 and Figure 3 As shown, the corbel 1 of this embodiment includes a vertical plate 11 , a supporting plate 12 and an end plate 13 , wherein one side of the vertical plate 11 abuts against the pier 2 , and the other side of the vertical plate 11 is connected to the supporting plate 12 .

[0046] In addition, the support plate 12 is arranged vertically, and the support plate 12 is arranged perpendicular to the vertical plate 11. At the same time, an extension section extending toward one side of the pier 2 is formed on the upper part of the support plate 12, so that the support plate 12 is in an inverted L shape as a whole, and the extension section can extend into the pier 2. Therefore, when the corbel 1 supports the gas construction structure, the pressure on the corbel 1 can be dispersed to the pier 2.

[0047] In addition, the end plate 13 is arranged on one side of the original pier 2 of the supporting plate 12 , and a mounting hole 14 is provided on the end plate 13 , which is used to be connected to a steel rod 21 preset in the pier 2 .

[0048] As described above, by setting the extension section of the support plate 12, the extension section can be extended into the pier 2, so that the pressure on the corbel 1 is transmitted to the pier 2 through the extension section, reducing the shear force on the steel rod 21, thereby increasing the supporting force and improving the supporting effect of the corbel 1.

[0049] Based on the above overall introduction, specifically, continue to combine Figure 1 , Figure 2 and Figure 3 As shown, the support plate 12 of this embodiment includes two plate bodies 121 arranged at intervals, and a first reinforcing plate 122 arranged between the two plate bodies 121. The first reinforcing plates 122 are arranged at both upper and lower ends of the extension section, and the first reinforcing plates 122 at the extension section and the two plate bodies 121 form a receiving channel 124. The support plate 12 is formed by the plate bodies 121 and the first reinforcing plates 122, thereby improving the structural strength of the support plate 12, and further improving the supporting force and supporting effect of the corbel 1. In a specific implementation, the two first reinforcing plates 122 at the upper and lower ends of the extension section extend toward the end plate 13 to improve the structural strength between the two plate bodies 121 and the entire support plate 12.

[0050] At the same time, in order to pass the steel rod 21 connected to the corbel 1 through the accommodating channel 124, the installation through hole 14 of this embodiment is connected to the accommodating channel 124, so that the steel plate can be passed through the accommodating channel 124, and then part of the shear force applied to the steel rod 21 is dispersed to the extension section, further improving the supporting effect of the corbel 1. In the specific implementation, the installation through hole 14 is a waist-shaped hole to facilitate the steel rod 21 and the end plate 13 to pass through.

[0051] In order to further improve the structural strength and supporting effect of the corbel 1, two supporting plates 12 are connected to the vertical plate 11 of this embodiment, and a second reinforcing plate 123 is provided between the two supporting plates 12. The arrangement of the two supporting plates 12 can further improve the overall structural strength and supporting force of the corbel 1. Two corresponding mounting holes 14 are also provided on the end plate 13, and are respectively connected to the two accommodating channels 124 on the two supporting plates 12, so as to improve the stability and structural strength of the corbel 1 when it is fixedly installed.

[0052] In order to ensure the stability of the construction structure overlapped on the corbel 1, a top plate 15 is provided on the top of the support plate 12 of this embodiment, and the top is connected to the end plate 13. By providing the top plate 15, the contact area between the structure supported by the corbel 1 and the corbel 1 can be increased. At the same time, the connection between the top plate 15 and the end plate 13 can further improve the structural stability of the corbel 1, and the top plates 15 on the two support plates 12 are a common top plate 15, thereby improving the structural stability between the two support plates 12.

[0053] In specific implementation, the vertical plate 11, end plate 13, top plate 15, plate body 121 of the support plate 12, first reinforcing plate 122 and second first reinforcing plate 122 involved in this embodiment can preferably be welded with Q235 steel plates to ensure the structural strength of the corbel 1.

[0054] In summary, the corbel 1 of the present embodiment, through the setting of the extension section of the support plate 12, can extend the extension section into the pier 2, so that the pressure exerted on the corbel 1 is transmitted to the pier 2 through the extension section. Compared with the prior art, the steel rod 21 or the screw connection and the welding part bear all the shear force, and the extension section can also bear part of the shear force, which reduces the shear force borne by the steel rod 21, thereby increasing the supporting force, thereby enhancing the supporting effect of the corbel 1.

[0056] This embodiment relates to a cap beam construction support structure, the overall structure of which is as follows: Figure 4 , Figure 6 and Figure 7 As shown, the cap beam construction support structure of this embodiment includes the corbel 1, distribution beam 3, platform support and formwork 7 support as described in Example 1.

[0057] The corbels 1 are arranged on two opposite sides of each pier 2, and reserved notches are arranged on the opposite sides of each pier 2, and each corbel 1 can be arranged in the corresponding reserved notches to facilitate the installation of the corbels 1. In specific implementation, during the pouring of the piers 2, bamboo plywood is used to support the template 7 at the reserved notches, and the template 7 of the reserved notches is reinforced with steel bars in a tic-tac-toe pattern to ensure the structural strength of the reserved notches, thereby facilitating the installation of the corbels 1 and ensuring the stability of the cap beam construction support structure.

[0058] In addition, each pier 2 is provided with a steel rod 21 for connecting two corbels 1. The end of the steel rod 21 can pass through the installation hole 14, and the end of the steel rod 21 is provided with a connecting piece 22 for connecting the corbels 1. Through the setting of the steel plate, the two ends of the steel rod 21 are connected to the two corbels 1 and tightened to fix the corbels 1 at the reserved groove of the pier 2.

[0059] In addition, two distribution beams 3 are overlapped on the corbels 1 on both sides of the plurality of piers 2, the platform bracket is erected on the two distribution beams 3, and the formwork 7 bracket is erected on the platform bracket. In specific implementation, a plurality of tension steel bars 21 are arranged between the two distribution beams 3 to further improve the structural stability of the distribution beams 3. In this embodiment, the cap beam of this embodiment is arranged on the two piers 2, so any distribution beam 3 is erected on the two corbels 1 of the two piers 2.

[0060] As described above, by providing the corbel 1 and the steel rod 21 as described above, the stability and structural strength of the platform support and the formwork 7 support can be improved, thereby improving the overall structural strength of the cap beam construction support structure.

[0061] Based on the above overall introduction, specifically, Figure 7 As shown, in order to facilitate the installation of the steel plate in the pier 2, a sleeve 23 is preset in the pier 2 of this embodiment, and the sleeve 23 is connected to the reserved notch. Specifically, when the pier 2 is cast, the sleeve 23 is installed in the pier 2. After the pier 2 is cast, the sleeve 23 is preset in the pier 2, so that the steel plate can be inserted in the pier 2 through the sleeve 23, so as to facilitate the installation of the steel rod 21, and avoid the steel rod 21 being directly cast in the pier 2, which causes the steel rod 21 to be corroded by raw materials such as concrete, resulting in a decrease in the strength of the steel rod 21. In specific implementation, the sleeve 23 can be a PVC pipe to ensure that the sleeve 23 has good strength and is not easy to be damaged.

[0062] In order to ensure the stability of the bracket 1 being fixed by the steel rod 21, continue to combine Figure 7 As shown, the connector 22 of this embodiment includes a double nut screwed on the end of the steel rod 21, and a gasket arranged between the double nut and the end plate 13. By arranging the double nut and the gasket, the double nut and the gasket can tighten the corbel 1, so that the corbel 1 can be stably secured on the reserved notch of the pier 2, and the double nut structure is simple and reliable, and has good anti-loosening performance. The two corbels 1 are anchored at both ends of the steel rod 21 through the double nut and the gasket. The steel rod 21 tightens the two corbels 1 at the opposite ends of the pier 2 to ensure the fixing effect of the corbel 1.

[0063] In order to improve the structural strength of the construction support structure and ensure the normal construction of the cap beam casting, the platform support of this embodiment includes a plurality of transverse pad beams 4 overlapped between the two distribution beams 3, and a plurality of longitudinal pad beams 5 erected between the transverse pad beams 4. By staggered arrangement of the transverse pad beams 4 and the longitudinal pad beams 5, a platform support for cap beam construction is formed, which can improve the structural strength of the platform support to ensure the safety of cap beam construction. Specifically, the transverse pad beams 4 and the longitudinal pad beams 5 are both I-beams to ensure their structural strength.

[0064] The formwork 7 support of this embodiment includes a support frame 6 mounted on a platform support, and a formwork 7 connected to the support frame 6 for pouring a cap beam. Specifically, the support frame 6 is a disc-type support, which is composed of a horizontal rod, a vertical rod, and a diagonal rod arranged between adjacent vertical rods to form a frame structure. In addition, as Figure 5 As shown, there are multiple support frames 6 arranged on the platform bracket, and each support frame 6 is arranged on the platform bracket through an adjustable support 61. The adjustable support 61 can adopt a conventional threaded support well known to technical personnel in this field, and can be arranged on the vertical rod of the support frame 6 to adjust the height of the support frame 6.

[0065] The support frames 6 are arranged around the two piers 2, and each support frame 6 is provided with a template 7, which can be used to cast the cap beam on the two piers 2 during construction. In specific implementation, the template 7 and the support frame 6 can also be connected by an adjustable support 61 to adjust the height of the template 7 to meet the construction requirements.

[0066] The cap beam construction support structure of this embodiment can improve the stability and structural strength of the platform support and the formwork 7 support through the arrangement of the corbel 1 and the steel rod 21 as described above, thereby improving the overall structural strength of the cap beam construction support structure.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
