[0001] The present application relates to the technical field of construction engineering, in particular to a construction method of a core tube between vertical multi-coupling beams. BACKGROUND

[0002] In the construction engineering, the core tube design of the super high-rise main structure is often designed as two-coupling beams, three-coupling beams or even multi-coupling beams due to the shear resistance requirement of the structure, the internal cavity between the upper and lower vertical coupling beams is narrow, and it is impossible to perform formwork, concrete pouring and other operation operations at one time. In the construction, the construction method of segmented formwork, segmented concrete pouring or pouring as a whole is often used. In the existing construction, the coupling beam is poured first, and then the core tube is poured. During the pouring of the core tube, the core tube needs to be poured in sections due to the narrow area between the coupling beams and the coupling beams, which leads to construction difficulties and cost waste.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] See Figure 1 A construction method for a core tube between multiple vertical connecting beams includes the following steps: providing several core tube casting templates 1; determining the positions of the connecting beams to be cast; setting the core tube casting templates 1 in the gap between the positions of two connecting beams to be cast; and spaced several core tube casting templates 1 in the gap; providing several back-ribbed square tubes 2; installing connecting beam splicing templates on the sides of the back-ribbed square tubes 2 corresponding to the core tube casting templates 1; forming splicing interfaces on the connecting beam splicing templates corresponding to the core tube casting templates 1; setting the connecting beam splicing templates on opposite sides of the core tube casting templates 1; and securing the splicing interfaces to the sides of the core tube casting templates 1; providing connecting beam casting templates; splicing the connecting beam casting templates and the connecting beam splicing templates together; forming a casting space with the connecting beam casting templates, the core tube casting templates 1, and the connecting beam splicing templates; and pouring concrete in the casting space.

[0025] In this invention, a preferred embodiment is as follows: The dimensions of the connecting beams and core tube are determined according to the on-site construction requirements. The core tube casting template 1, connecting beam casting template, and connecting beam splicing template are prefabricated in a prefabrication plant. Preferably, the width of the connecting beam splicing template matches the spacing between two adjacent connecting beams required by the on-site construction requirements. The prefabricated core tube casting template 1, connecting beam casting template, and connecting beam splicing template are transported to the construction site. According to the on-site construction drawings, the core tube casting template 1 is erected between the adjacent connecting beams at their respective pouring positions. The two connecting beam splicing templates are placed on opposite sides of the core tube. Preferably, the splicing joints of the two connecting beam splicing templates form a fixing opening that matches the dimensions of the core tube casting template 1. The connecting beam is then cast... The formwork and the connecting beam splicing formwork are spliced ​​together. Preferably, a vertical plate is formed on the side of the connecting beam splicing formwork away from the core tube casting formwork 1. The vertical plate extends along the edge of the connecting beam splicing formwork and is set at the top of the connecting beam splicing formwork. A limit plate is set at the bottom of the connecting beam casting formwork corresponding to the position of the vertical plate. During splicing, the side of the vertical plate and the side of the limit plate are fitted together to splice. A support is erected at the construction site. The top of the support is placed against the bottom of the connecting beam splicing formwork and the bottom of the connecting beam casting formwork to support the bottom of the connecting beam splicing formwork and the connecting beam casting formwork. Concrete is poured in the pouring space. After the concrete reaches the designed strength, each casting formwork is removed and the concrete structure is cured.

[0026] Furthermore, when the connecting beam splicing template is set on opposite sides of the core tube casting template 1, adjusting bolts 3 are provided. The back rib square tube 2 has fixing holes corresponding to the adjusting bolts 3. The adjusting bolts 3 are inserted between the two oppositely arranged back rib square tubes 2. Part of the adjusting bolts 3 are exposed on the two back rib square tubes 2. Adjusting nuts 4 are set on the exposed part of the adjusting bolts 3. The adjusting nuts 4 are screwed on so that the connecting beam splicing template is tightly attached to the side of the core tube casting template 1. Preferably, both ends of the adjusting bolt 3 are exposed on the two back rib square tubes 2, and adjusting nuts 4 are provided on both exposed parts. By adjusting nuts 4 against the back rib square tubes 2, the splice joint of the connecting beam formwork can be locked on the side of the core tube casting formwork 1, so as to reduce the gap between the connecting beam formwork and the core tube casting formwork 1. Preferably, when pouring concrete, a rubber strip can be installed between the core tube casting formwork 1 and the connecting beam formwork to prevent concrete from overflowing from the gaps during pouring.

[0027] Furthermore, after inserting the adjusting bolt 3 into the back rib square tube 2, four corner pads 5 are fitted onto the extension portion of the adjusting bolt 3, and the adjusting nut 4 is screwed onto the extension portion of the adjusting bolt 3. The adjusting nut 4 pushes against the four corner pads 5 and abuts against the back rib square tube 2.

[0028] Furthermore, before pouring concrete into the pouring space, reinforcing bars are tied within the pouring space. By tying reinforcing bars within the pouring space, the strength of the poured concrete structure is ensured.

[0029] Furthermore, before pouring concrete into the casting space, a release agent is applied to the inner wall of the core tube casting formwork 1. Applying the release agent facilitates subsequent demolding of the core tube casting formwork 1.

[0030] Furthermore, before pouring concrete into the casting space, a pouring port is opened on the core tube casting template 1, and a pouring pipe 6 is provided. The pouring pipe 6 is inserted into the pouring port, and concrete is poured into the pouring pipe 6 to pour concrete into the core tube casting template 1. The pouring pipe 6 facilitates the pouring of the core tube casting template 1, thereby avoiding uneven pouring.

[0031] Furthermore, during the installation of the connecting beam casting formwork, a testing instrument is provided to level the bottom of the connecting beam casting formwork.

[0032] Furthermore, after pouring concrete in the pouring space, once the concrete reaches the design strength, the core tube pouring formwork 1 is removed.

[0033] Furthermore, after removing the core tube casting template 1, the concrete slag on the surface of the core tube casting template 1 is cleaned.

[0034] Furthermore, before assembling the core tube casting template 1, the dimensions of the core tube casting template 1 are determined according to the on-site construction requirements.

[0035] The following describes the construction process of a core tube between vertical multi-beams according to the present invention.

[0036] The dimensions of the connecting beams and core tube are determined according to the on-site construction requirements. The core tube casting template 1, connecting beam casting template, and connecting beam splicing template are prefabricated in the prefabrication plant. Preferably, the width of the connecting beam splicing template matches the spacing between two adjacent connecting beams required by the on-site construction. The prefabricated core tube casting template 1, connecting beam casting template, and connecting beam splicing template are transported to the construction site. According to the on-site construction drawings, the core tube casting template 1 is erected between the adjacent connecting beams at their respective pouring positions. The two connecting beam splicing templates are placed on opposite sides of the core tube. Preferably, the splicing joints of the two connecting beam splicing templates form a fixing opening that matches the dimensions of the core tube casting template 1. The connecting beam casting template and the connecting beam splicing template are then spliced ​​together. Preferably, the connecting beam splicing... A vertical plate is formed on the side of the template away from the core tube casting template 1. The vertical plate extends along the edge of the connecting beam splicing template and is set at the top of the connecting beam splicing template. A limit plate is set at the bottom of the connecting beam casting template corresponding to the position of the vertical plate. During splicing, the side of the vertical plate and the side of the limit plate are fitted together for splicing. A support is erected at the construction site. The top of the support is placed against the bottom of the connecting beam splicing template and the bottom of the connecting beam casting template, thereby supporting the bottom of the connecting beam splicing template and the connecting beam casting template. Concrete is poured in the pouring space. After the concrete reaches the designed strength, each casting template is removed, and the concrete structure is cured. Concrete residue on the surface of the core tube casting template 1 is removed to facilitate the next use.
