[0036] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0037] In the prior art, after the prefabricated steel pedestal bottom formwork and the side formwork are closed, the problem of slurry leakage between the formworks is usually solved by manually filling with foam glue or sticking double-sided tape. However, this method cannot solve the problem of slurry leakage very well, and the operation process is also relatively cumbersome. The sticking is prone to wrinkles, the formed beams and slabs are not smooth, and the double-sided tape or foam glue cannot be reused. After each pouring, the double-sided tape or foam glue needs to be removed and re-sticked or filled before the next pouring, which is labor-intensive, affects the construction progress, and increases the construction cost.

[0038] The following is a detailed description of the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems with specific embodiments. It should be noted that the following embodiments can refer to, draw on, or combine with each other, and the same terms, similar features, and similar implementation steps in different embodiments will not be repeated.

[0039] The embodiment of the present application provides a prefabricated steel pedestal bottom mold anti-leakage slurry structure, such as Figure 1-5 As shown, the prefabricated steel pedestal bottom formwork anti-leakage structure includes: a pedestal 11, a panel 12, a support member 13, and an elastic member 14.

[0040] The panel 12 is disposed on the top of the base 11 , and along the first direction a, the side of the panel 12 extends beyond at least a portion of the side of the base 11 .

[0041] The support member 13 is arranged on the side of the base 11 and includes an outward-opening groove, or forms an outward-opening groove with the portion of the panel 12 extending beyond the side of the base 11. The groove extends along the second direction b, and the second direction b is perpendicular to the first direction a.

[0042] The elastic member 14 has a portion filling the groove and another portion outside the groove along the first direction a; and has the same length as the groove along the second direction b.

[0043] In an embodiment of the present application, a panel 12 is arranged on the top of the pedestal 11, and along a first direction a perpendicular to the longitudinal direction of the pedestal 11, the side of the panel 12 extends beyond the side of the pedestal 11; the support member 13 is arranged on the side of the pedestal 11, and forms a groove with the portion of the panel 12 extending beyond the side of the pedestal 11, and the elastic member 14 is arranged in the groove, so that when the prefabricated steel pedestal bottom mold and the side mold are combined, the side mold squeezes the elastic member 14, so that the elastic member 14 can completely fill the gap between the side mold and the prefabricated steel pedestal bottom mold, thereby achieving a close fit between the side mold and the prefabricated steel pedestal bottom mold, thereby preventing the problem of leakage of slurry during concrete pouring after the prefabricated steel pedestal bottom mold and the side mold are combined, thereby improving the casting quality of the T-beam.

[0044] It should be noted that in this application, the second direction b refers to the longitudinal direction of the pedestal 11, and the first direction a refers to the transverse direction of the pedestal 11. The prefabricated steel pedestal bottom formwork anti-leakage structure is that the prefabricated steel pedestal bottom membrane serves as the bottom formwork for T-beam casting.

[0045] Optionally, in one embodiment of the present application, Figure 4-5 As shown, along the first direction a, the support member 13 is away from the side of the base 11 and is flush with the side of the panel 12.

[0046] In the embodiment of the present application, along the first direction a, the side formwork is arranged on the side of the pedestal 11 and connected to the side of the panel 12, and the support member 13 is arranged away from the side of the pedestal 11 and flush with the side of the panel 12, so as to avoid the side of the support member 13 exceeding the side of the panel 12, resulting in a gap between the panel 12 and the side formwork, resulting in the prefabricated steel pedestal bottom formwork and the side formwork being unable to fit tightly, affecting the quality of T-beam casting; in addition, the support member 13 is arranged away from the side of the pedestal 11 and flush with the side of the panel 12, that is, the side of the groove is flush, so that when the side formwork is combined with the prefabricated steel pedestal bottom formwork, the side formwork squeezes the elastic member 14 in the groove, and the side formwork is tightly fitted with the side of the support member 13 and the side of the panel 12, so that the elastic member 14 can completely fill the gap between the side formwork and the prefabricated steel pedestal bottom formwork, thereby avoiding the problem of leakage of slurry during concrete pouring after the prefabricated steel pedestal bottom formwork and the side formwork are combined, thereby improving the casting quality of the T-beam.

[0047] Moreover, if the side of the panel 12 exceeds the side of the support member 13 along the first direction a, when the side template is in contact with the side of the panel 12, there will be a gap between the side of the support member 13 and the side template, which may easily cause the elastic member 14 to leak out of the gap between the side template and the support member 13, affecting the sealing effect. Therefore, in this application, the side of the support member 13 away from the base 11 is set to be flush with the side of the panel 12.

[0048] Optionally, in one embodiment of the present application, Figure 4-5 As shown, the dimension of the elastic member 14 along the first direction a is greater than the depth of the groove.

[0049] In an embodiment of the present application, the dimension of the elastic member 14 along the first direction a is set to be greater than the depth of the groove, so that when the side formwork is molded with the prefabricated steel pedestal bottom formwork, the side formwork squeezes the portion of the elastic member 14 that exceeds the groove, causing the elastic member 14 to deform and fill the gap between the side formwork and the prefabricated steel pedestal bottom formwork, so that the side formwork and the prefabricated steel pedestal bottom formwork are tightly fitted, thereby avoiding the problem of leakage of concrete during concrete pouring after the side formwork and the prefabricated steel pedestal bottom formwork are molded together, thereby improving the casting quality of the T-beam.

[0050] Optionally, in the embodiment of the present application, the elastic member 14 includes a rubber strip, etc. The elastic member 14 is located in the groove, and does not need to be assembled or replaced before and after each pouring. It only needs to be replaced when the elastic member 14 is severely worn, thereby saving construction time and improving construction efficiency.

[0051] Optionally, in one embodiment of the present application, Figure 5 As shown, the support 13 comprises a steel member.

[0052] In the embodiment of the present application, the steel member comprises a steel strip, which is arranged along the side of the base 11 in the first direction a and can be connected to the base 11 by welding or other means. The steel strip and the portion of the panel 12 that extends beyond the side of the base 11 form a groove for accommodating the elastic member 14. The support member 13 is a steel member, which has a simple structure and is easy to operate.

[0053] Optionally, in one embodiment of the present application, Figure 5 As shown, the side of the panel 12 exceeds the side of the entire base 11.

[0054] The anti-leakage slurry structure of the prefabricated steel pedestal bottom mold further includes ear seats 15 arranged on both sides of the bottom of the pedestal 11.

[0055] In an embodiment of the present application, the side edges of the panel 12 extend beyond the side edges of the entire pedestal 11, and ear seats 15 are provided on both sides of the bottom of the pedestal 11. One end of the side formwork is connected to the ear seat 15. Along the first direction a, the side edges of the ear seat 15 close to the pedestal 11 are flush with the side edges of the panel 12, so that when the side formwork is closed with the prefabricated steel pedestal bottom formwork, the side edges of the panel 12 and the side edges of the ear seat 15 are tightly fitted with the side formwork, thereby preventing the side formwork from tilting and improving the casting quality of the T-beam.

[0056] Optionally, in one embodiment of the present application, Figure 4 As shown, the pedestal 11 includes a first component 111 and a second component 112; the second component 112 is arranged on the top of the first component 111, and the first component 111 extends along the first direction a; the support member 13 includes a first channel steel, and the second component 112 and the support member 13 both extend along the second direction b; along the first direction a, the support member 13 is arranged on the outside of the second component 112, and the opening of the first channel steel faces outward.

The support member 13 can be a first channel steel, and the opening of the first channel steel is facing the side away from the second component 112. The elastic member 14 is arranged in the first channel steel, so that the elastic member 14 only needs to be installed in the first channel steel, and there is no need to repeatedly stick double-sided tape or fill foam glue, which saves time and effort.

[0058] Optionally, in one embodiment of the present application, Figure 4 As shown, the panel 12 is located on the top of the second member 112 ; the top of the first channel steel is in contact with the bottom of the panel 12 .

[0059] In the embodiment of the present application, the panel 12 is arranged at the top of the second component 112, and the top of the first channel steel serving as the support member 13 is fitted with the bottom of the panel 12, so that there is no gap between the bottom of the panel 12 and the top of the first channel steel, thereby avoiding that when the side formwork squeezes the elastic member 14, the elastic member 14 is filled in the gap between the bottom of the panel 12 and the top of the first channel steel; thereby, the squeezed elastic member 14 can be completely filled in the gap between the side formwork and the bottom formwork of the prefabricated steel pedestal, so that the side formwork and the bottom formwork of the prefabricated steel pedestal are tightly fitted, avoiding the problem of leakage, thereby improving the casting quality.

[0060] Optionally, in one embodiment of the present application, Figure 4 As shown, along the first direction a, the panel 12 exceeds the side of the second component 112, and the side of the first component 111 exceeds the side of the second component 112; along the first direction a, the side of the panel 12 is flush with the side of the first component 111.

[0062] Optionally, in one embodiment of the present application, Figure 4 As shown, the second component 112 includes two second channel steels; the openings of the two second channel steels are relatively facing inward.

[0063] In the embodiment of the present application, the second member 112 comprises two second channel steels, the openings of which are arranged opposite each other. The support member 13 is disposed on one side of the second channel steel, with the opening of the second channel steel facing away from the support member 13 and oriented in the opposite direction to the opening of the first channel steel. By selecting different types of channel steel, the height of the second member 112 can be adjusted, thereby adjusting the thickness of the prefabricated steel pedestal base mold. Furthermore, by selecting channel steel as the second member, the structure is simplified.

[0064] Optionally, the first component 111 may be made of I-beam, which can reduce the weight of the prefabricated steel pedestal bottom mold.
