Description

Technical Field

[0001] The utility model belongs to the technical field of bottom molds for cap beams, and particularly relates to a bottom mold structure for cast-in-place cap beams. Background Art

[0002] The cap beam formwork is a tool commonly used for casting cap beams on construction sites. It is usually made in the factory and assembled on site. It has the advantages of convenient transportation and simple operation.

[0003] However, due to the precision of the production process and the existence of precise errors in construction, the cap beam formwork is basically assembled with perfect fit. The bottom formwork of this type is often affected by weather, labor and other factors, which can cause the formwork to expand and fit too tightly, resulting in the formwork getting stuck and unable to be removed. This increases the difficulty of removing the formwork, greatly affecting the speed of removing the formwork and affecting construction efficiency. Summary of the invention

[0004] The utility model aims to overcome the deficiencies in the prior art and provide a bottom formwork structure for a cast-in-place cap beam, which has a reasonable structure, is convenient for demoulding, and increases construction efficiency.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A bottom mold structure for a cast-in-place cap beam comprises an arc bottom mold, a flat bottom mold and a triangular bottom mold. The two ends of the flat bottom mold are respectively connected with arc bottom molds. The flat bottom mold serves as the bottom mold of the cap beam. One end of the arc bottom mold is connected with a triangular bottom mold. The triangular bottom mold is a triangular structure that supports the oblique side of the cap beam and cooperates with the arc bottom mold to embrace the supporting column. The arc bottom mold is mainly composed of an arc support plate, a first arc strip steel, a first angle channel steel and a limiting angle steel rod. The arc support plate is a plate structure with a semicircular notch structure at one end. The semicircular notch of the arc support plate is used for The support column of the cap beam body is buckled, and a first arc strip steel is fixedly attached to the inner side of the semicircular recess of the circular arc bottom mold, and the first arc strip steel is used to protect the arc support plate to avoid friction damage with the support column. First angle channel steels are provided at both ends of the first arc strip steel, and the first angle channel steels are fixedly arranged on the bottom side of the arc support plate. A limiting angle steel rod is fixedly arranged on the bottom side of the other end of the arc support plate, and the limiting angle steel rod is arranged on the inner side of the corresponding arc support plate end to form a tongue and groove, and the width of the tongue and groove is 8mm. The flat bottom mold includes a connecting support plate and a positioning angle steel rod. The support plate is a flat plate structure and is provided with positioning angle steel rods at both ends. The positioning angle steel rods are arranged at the bottom of the connecting support plate and extend to the outside of the end side to form a female opening. The width of the female opening is 5mm. The arc bottom molds at both ends of the flat bottom mold are connected by tongue-and-groove to set up the female opening. When installing the bottom mold, firstly, the triangular bottom mold and the arc bottom mold are fixed to the corresponding support columns, and then the flat bottom mold is placed between the two arc bottom molds, so that the tongue-and-groove of the arc bottom mold is set at the corresponding female opening position, and then the flat bottom mold is completely fixed, so that the arc bottom mold, The flat bottom formwork and the triangular bottom formwork are connected in sequence to form an integral cap beam bottom formwork. Because the tongue and groove is 8mm and the female mouth is 5mm, there will be a 3mm gap between the limiting angle steel rod and the corresponding positioning angle steel rod, instead of a tightly docked state. Therefore, when removing the formwork, you only need to knock the flat bottom formwork slightly to loosen it. The gap between the limiting angle steel rod and the positioning angle steel rod will act as a breathing gap, which will have a certain fault tolerance structure for the prefabrication production process and construction errors, avoiding the expansion of the formwork after assembly, resulting in too tight fit, which is difficult to disassemble and affects the construction efficiency.

[0007] Furthermore, the triangular bottom mold includes an oblique support plate, a bottom connecting plate, and a butt joint plate.

The oblique support plate is fitted to the cap beam body as the bottom mold on the side. One end of the bottom connecting plate is fixedly connected to a butt joint plate with a semicircular recess. The semicircular recess of the butt joint plate and the semicircular recess of the arc bottom mold are used to embrace the supporting column. The butt joint plate is butt jointed with the corresponding arc bottom mold, and then a complete bottom mold plate is formed by the oblique support plate, the butt joint plate, the arc support plate, and the connecting support plate. A plurality of transverse ribs and longitudinal ribs are welded on the bottom sides of the arc support plate, the connecting support plate, the bottom connecting plate, and the butt joint plate. The transverse ribs and the longitudinal ribs are staggered and fixed to intersect. The longitudinal ribs and the transverse ribs are used to increase the firmness of the corresponding plate body and increase the service life.

[0008] Furthermore, a second arc strip steel is fixedly attached in the semicircular recess of the docking plate, and the second arc strip steel is mainly used to protect the inner wall of the semicircular recess of the docking plate to avoid damage caused by friction. Second angle channel steels are provided at both ends of the second arc strip steel, and the second angle channel steels are fixed to the bottom of the docking plate and correspond to the first angle channel steels adjacent to the arc template. The second angle channel steels are fixedly connected to the corresponding first angle channel steels by bolts, thereby realizing the fixed connection between the triangular bottom mold and the arc bottom mold.

[0009] Furthermore, the two ends of the limiting angle steel rod are fixedly connected to the two ends of the corresponding positioning angle steel rod by bolts respectively. When the bottom mold is installed, after the flat bottom mold is placed, the arc support plate is fixedly connected to the support plate by bolts, thereby realizing the connection between the arc bottom mold and the flat bottom mold.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model discloses a limiting angle steel rod is fixedly provided on the bottom side of one end of the arc support plate in the middle of the utility model, and the limiting angle steel rod is arranged on the inner side of the corresponding arc support plate end to form an 8mm tongue and groove, the connecting support plate is a flat structure and is provided with positioning angle steel rods at both ends, the positioning angle steel rods are arranged at the bottom of the connecting support plate and extend to the outside of the end side to form a 5mm female opening, the arc bottom molds at both ends of the flat bottom mold are connected by setting the female opening through the tongue and groove, and the flat bottom mold is placed between the two arc bottom molds, so that the tongue and groove of the arc bottom mold are set at the corresponding female opening position, because the tongue and groove is 8mm and the female opening is 5mm, and thus there will be a 3mm gap between the limiting angle steel rod and the corresponding positioning angle steel rod, instead of a tightly docked state, and thus when removing the mold, the flat bottom mold only needs to be slightly knocked to loosen it, and the gap between the limiting angle steel rod and the positioning angle steel rod will play the role of a breathing gap, thereby having a certain fault-tolerant structure for prefabricated production process and construction errors, avoiding the mold expansion after the template is assembled, resulting in too tight fit, and difficult disassembly, affecting construction efficiency.
