Construction method of Y-shaped structural column

Abstract

The present invention discloses a construction method for a Y-shaped structural column. When pouring concrete in a column bottom mold barrel, a vibrating rod is connected to a vibrating rib through a connecting sleeve, and the vibration generated by the vibrating rod is transmitted to the concrete in the column bottom mold barrel through the vibrating rib, so that the concrete in the column bottom mold barrel can be vibrated and poured densely under the obstruction of the column top mold barrel. On the other hand, when pouring concrete in two column top mold barrels at the same time, due to the existence of an exhaust port at the junction of the lower ends of the two column top mold barrels, at the beginning of pouring concrete, the air in the column top mold barrel is discharged through the exhaust port under the drive of the concrete, so that the concrete in the column top mold barrel is poured densely and the root rot of the concrete solid body in the column top mold barrel is avoided. The present invention solves the problem that the pouring and vibration construction of the Y-shaped column in the stadium-type building structure is prone to loose pouring.

Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a construction method of a Y-shaped structural column. Background Art

[0002] In some large stadium-type building structures, there are many special-shaped columns. Among these special-shaped columns, especially some Y-shaped columns, the Y-shaped columns are relatively high, and the inclination angles of the two upper V-shaped columns are relatively large, making it difficult to pour and vibrate the concrete in the lower vertical part of the Y-shaped column. On the other hand, the segmented construction of the upper V-shaped part of the Y-shaped column will form a cold joint section. In order to ensure the smooth continuous pouring of concrete, the two inclined columns of the upper V-shaped part of the Y-shaped column need to be poured at the same time. The simultaneous pouring of both sides will form air accumulation and compression at the bottom of the V-shaped inclined column, resulting in root rot at the bottom of the V-shaped inclined column.

[0003] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0009] Before the concrete in the column bottom mold barrel initially sets, concrete is poured and vibrated in the two column top mold barrels at the same time, so that the air in the two column top mold barrels is discharged through the exhaust holes;

[0010] After the concrete slurry continuously overflows from the exhaust hole, the exhaust hole is blocked.

[0011] Furthermore, the vibrating ribs are centrally arranged in the column top mold cylinder and the column bottom mold cylinder.

It is to be understood that the specific embodiments described herein are only used to explain the relevant inventions, rather than to limit the inventions. It should also be noted that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] Reference Figures 1 to 4 As shown, the present invention provides a construction method of a Y-shaped structural column, comprising the following steps:

[0026] S1: A column bottom mold cylinder 1 is vertically installed at the construction position of the Y-shaped structural column, and the upper ends of the column bottom mold cylinder 1 are respectively obliquely upward and outward to form two column top mold cylinders 2, and the two column top mold cylinders 2 are connected with the column bottom mold cylinder 1 to form a Y-shaped casting space, and an exhaust hole is opened at the top of the intersection of the lower ends of the two column top mold cylinders 2.

[0027] S2: A vibrating rib 3 is movably arranged in the column top mold tube 2, and the vibrating rib 3 is arranged along the length direction of the column top mold tube 2. The upper end of the vibrating rib 3 extends to the upper port of the column top mold tube 2, and the lower end of the vibrating rib 3 extends to the bottom of the column bottom mold tube 1.

[0028] S3: pour concrete in the column bottom mold tube 1. At the same time, the vibrating rod is detachably installed on the upper end of the vibrating bar 3 through the connecting sleeve. The vibrating rod is turned on to transmit the vibration to the concrete in the column bottom mold tube 1 through the vibrating bar 3, so that the concrete in the column bottom mold tube 1 is vibrated and compacted.

[0029] S4: Before the concrete in the column bottom mold barrel 1 initially sets, concrete is poured and vibrated in the two column top mold barrels 2 at the same time, so that the air in the two column top mold barrels 2 is discharged through the exhaust holes 20.

[0030] In this embodiment, the steel bar structure 6 includes a vertical section and two oblique sections. The oblique section is connected to the upper end of the vertical section. The lower ends of the two oblique sections are simultaneously connected to the upper end of the vertical section. The upper ends of the two oblique sections are respectively arranged obliquely upward toward the opposite sides of the vertical section. The distance between the two oblique sections gradually increases from bottom to top.

[0031] Specifically, the vertical section includes a plurality of vertical main bars and first stirrups. The plurality of vertical main bars are arranged in a circle along the circumferential direction of the Y-shaped structural column. The first stirrups are arranged outside the plurality of vertical main bars. The plurality of first stirrups are arranged at intervals along the length direction of the vertical main bars.

[0032] The oblique section includes a plurality of oblique main bars and a second stirrup. The plurality of oblique main bars are arranged in a ring shape. The lower ends of the plurality of oblique main bars are connected to the upper end of the vertical section. The second stirrup is arranged outside the plurality of oblique main bars. The plurality of second stirrups are arranged at intervals along the length direction of the oblique main bars.

[0033] Before installing the column bottom mold, first tie the vertical section of the steel structure 6 of the Y-shaped structural column at the construction position. After the vertical section is tied, install the column bottom mold on the outside of the vertical section so that the column bottom mold is sleeved on the outside of the vertical section. After the column bottom mold is installed, tie the upper ends of the vertical sections to form oblique sections respectively, so that the two oblique sections are respectively connected to the upper ends of the vertical sections. Wherein, when tying the oblique sections, the lower part of the vibrating bar is first movably inserted into the vertical section so that the vibrating bar is movably arranged in the vertical section. After the oblique section is tied, the upper part of the vibrating bar is movably arranged in the oblique section, and the upper end of the vibrating bar extends to the outside of the column top mold. After the oblique section is tied, install the column top mold at the upper end of the column bottom mold so that the column top mold is respectively sleeved on the outside of the oblique section. An exhaust hole is provided at the upper part of the intersection of the lower ends of the two column top mold barrels, and an observation hole is provided at the upper end of the column bottom mold barrel. Subsequently, concrete is poured in the column bottom mold barrel and the column top mold barrel in sequence.

[0034] When pouring concrete in the column bottom mold tube, the vibrating rod is connected to the vibrating rib through the connecting sleeve, and the vibration generated by the vibrating rod is transmitted to the concrete in the column bottom mold tube through the vibrating rib, so that the concrete in the column bottom mold tube can be vibrated and poured densely even under the obstruction of the column top mold tube.

[0035] On the other hand, when pouring concrete in two column top molds at the same time, due to the existence of exhaust holes at the intersection of the lower ends of the two column top molds, at the beginning of pouring concrete, the air in the column top molds is discharged through the exhaust holes driven by the concrete, thereby making the concrete in the column top molds densely poured and avoiding root rot of the concrete solidified body in the column top molds.

[0036] The construction method of the Y-shaped structural column of the present invention is to insert vibrating bars at the same time when the steel bar structure of the Y-shaped structural column is tied, and the vibrating bars include a vertical section and an inclined section. The inclined section is connected to the upper end of the vertical section. The vertical section is arranged in a column bottom mold tube, and the inclined section is arranged in a column top mold tube. The upper end of the inclined section is exposed to the outside of the column top mold tube. Before pouring concrete, a connecting sleeve is screwed into the thread of the upper end of the inclined section, and then a concrete vibrator is inserted into the other end of the connecting sleeve, and the concrete vibrator is turned on when pouring concrete.

[0037] When pouring the lower concrete of the Y-shaped structural column, if the observation hole shows continuous overflow of concrete slurry, the observation hole is immediately blocked and the vibration with the vibrating rod is stopped. Then, concrete is poured into the pouring space from the upper ports of the two column top molds, and the two sides of the column top mold are vibrated with vibrating rods at the same time. If the exhaust hole shows continuous overflow of concrete slurry, the exhaust hole is blocked.

[0038] The construction method of the Y-shaped structural column of the present invention simultaneously casts in two upper column top mold cylinders, thereby avoiding the formation of cold joints due to separate casting.

[0039] As a preferred implementation, after the concrete slurry continuously overflows from the exhaust hole 20, the exhaust hole 20 is blocked.

[0040] The construction method of the Y-shaped structural column of the present invention provides an exhaust hole at the intersection of the lower ends of the two column top mold cylinders, so that when the two column top mold cylinders are poured at the same time, the concrete can be used to squeeze and discharge the air through the exhaust hole, thereby preventing the squeezed air from hindering the flow of concrete in the pouring space when the two column top mold cylinders are poured at the same time, ensuring that the air wrapped in the concrete can be discharged smoothly, and ensuring that the concrete at the important node parts of the Y-shaped structural column is poured densely.

[0041] As a preferred embodiment, an observation hole 10 is opened on the upper portion of the column bottom mold cylinder 1.

[0042] The construction method of the Y-shaped structural column of the present invention provides an observation hole on the upper part of the column top mold barrel for observing the internal concrete pouring height of the column top mold barrel. When the observation hole continuously overflows with concrete slurry, it can be judged that the lower part of the Y-shaped structural column is poured.

[0043] The vibrating rib 3 is centrally arranged in the column top mold tube 2 and the column bottom mold tube 1. The connecting sleeve has two opposite ends, one end of the connecting sleeve is connected to the vibrating rod, and the other end of the connecting sleeve is detachably sleeved on the upper end of the vibrating rib 3. Specifically, the other end of the connecting sleeve is formed with an internal thread, the upper end of the vibrating rib 3 is formed with an external thread, and the upper end of the vibrating rib 3 is threadedly connected to the other end of the connecting sleeve. The vibrating rod is detachably inserted into one end of the connecting sleeve.

[0044] The construction method of the Y-shaped structural column of the present invention adopts a method of arranging a full-length vibrating bar for auxiliary vibration inside the Y-shaped casting space to solve the problem that the Y-shaped structural column is too high and the upper V-shaped opening has a large inclination angle, and the vibrating rod cannot smoothly penetrate into the lower part of the Y-shaped structural column for vibration. When the concrete vibrating rod is turned on, the vibrating rod and the vibrating bar resonate, thereby achieving the concrete vibration effect on the lower part of the special-shaped structural column.

[0045] As a preferred embodiment, a tie rod 5 is connected between the two column top mold cylinders 2. After the oblique section of the steel bar structure is tied, the column top mold cylinder outside the oblique section is installed, and the two column top mold cylinders are tied together by the tie rod to avoid the risk of overturning when pouring concrete in the column top mold cylinder.

[0046] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the present application.
