Description

Technical Field

[0001] This invention relates to the field of building construction technology. More specifically, this invention relates to a method for simultaneous construction of exterior wall panels and the main structure. Background Technology

[0002] With the booming development of high-rise buildings, construction units have increasingly higher requirements for construction period. In the construction of high-rise buildings, the traditional construction method is to carry out the construction of the main structure first, and then carry out the construction of the exterior wall panels after the main structure is completed. For some high-rise buildings with tight construction period requirements, the traditional construction method will not be able to meet the requirements of timely completion.

[0003] To shorten the construction period and improve efficiency, existing technologies provide a method for simultaneous construction of exterior wall panels and the main structure. This method defines any floor of a high-rise building as floor N, the upper X floors as floor N+X, and the lower X floors as floor NX. The exterior wall panels of each floor are constructed simultaneously with the main structure. For example, Chinese patent publication number CN115162556A, published on 2022-10-11, entitled "A Method for Prefabricated Exterior Wall Panels Constructed Simultaneously with the Main Structure," discloses a method including prefabricated wall processing and the assembly and installation between the prefabricated walls and the main structure. This method for constructing high-rise prefabricated building structures shortens the overall construction period, but it suffers from the inconvenience of transporting, hoisting, and installing single-sided exterior wall panels as a whole.

[0004] Therefore, there is an urgent need to design a construction method that allows for simultaneous construction and installation of the exterior wall and main structure, while also increasing the overall strength of the exterior wall. This would shorten the construction period, improve convenience, and enable the exterior wall to withstand its own weight and wind loads over a long period, thereby reducing the probability of damage. Summary of the Invention

[0005] One object of the present invention is to solve at least the above-mentioned problems and to provide at least the advantages that will be described later.

Detailed Implementation

[0059] The present invention will be further described in detail below with reference to embodiments, so that those skilled in the art can implement it based on the description.

[0060] like Figures 1-11 As shown, the method for simultaneous construction of exterior wall panels and main structure includes the following steps:

[0061] I. Exterior Wall Panel Processing and Manufacturing Stage

[0062] Based on the architectural drawings, the dimensions of the exterior wall panels and supporting components are calculated, and the exterior wall panels and supporting components are prefabricated according to the calculated dimensions.

[0063] II. On-site installation and construction phase

[0064] 2.1 Construction of N floors (N≥1)

[0065] 2.1.1 Set the lowest floor where the exterior wall panels are installed as the reference floor, defined as floor N. Construct the concrete floor slab 1 of the reference floor, wherein the top surface of the concrete floor slab 1 of the reference floor has strip-shaped grooves 10 corresponding to each exterior wall of the floor.

[0066] 2.1.2 The column reinforcement 11 of the base layer is tied to form a reinforcement cage. There is a reinforcement cage at both ends of any strip groove 10, and a common reinforcement cage at the ends of two adjacent strip grooves 10 along the circumference of the concrete floor slab.

[0067] 2.1.3. Exterior wall assembly

[0068] (1) For exterior walls without pre-reserved installation holes (doors, windows, etc.), the exterior wall assembly includes the following steps:

[0069] I. Assume the exterior wall consists of M layers of exterior wall panels (M≥3), defined from bottom to top as 1, 2, ..., M;

[0070] II. Install the first layer, including the following steps:

[0071] ① Install a horizontal through-tube 2, which matches the strip groove 10 of the concrete floor slab 1. The top surface of the horizontal through-tube 2 protrudes from the strip groove 10. Each side wall of the horizontal through-tube 2 is provided with a first through hole 21 that communicates with the inner cavity of the horizontal through-tube 2. The horizontal through-tube 2 is provided with a plurality of mounting holes 20 at intervals along its length. The mounting holes 20 penetrate the top and bottom surfaces of the horizontal through-tube 2. The principle of the layout of the first through holes 21 is to increase the contact area between each side wall of the horizontal through-tube 2 and each contact surface through the first through holes 21 while ensuring the strength of the horizontal through-tube 2. Preferably, the height of the horizontal through-tube 2 (the height in the vertical direction after matching the strip groove 10) is twice the depth of the strip groove 10.

[0072] ② Install the bottom vertical through-pipe 3 and the middle outer wall panel 4 alternately from left to right, with the bottom vertical through-pipe 3 installed to the right of the rightmost middle outer wall panel 4. That is, if the number of middle outer wall panels 4 in the first layer is K, then the number of bottom vertical through-pipes 3 is K+1. The bottom vertical through-pipes 3 and the middle outer wall panel 4 are installed alternately, wherein:

[0073] The bottom vertical through-tube 3 includes a first middle vertical tube 30 and first end tubes 31 located at both ends of the first middle vertical tube 30 and communicating with the first middle vertical tube 30. The projection of the first middle vertical tube 30 on the horizontal plane falls within the projection range of the first end tubes 31 on the horizontal plane. All the first end tubes 31 of the bottom vertical through-tubes 3 of the first layer are matched and installed one by one with the mounting holes 20 in the middle of the horizontal through-tube 2 (excluding the mounting holes 20 at both ends), and the top surface of the first end tube 31 protrudes out of the corresponding mounting hole 20. Preferably, the protrusion height is 1 / 2 of the height of the first end tube 31; wherein, the four sides of the first end tube 31 and the side opposite to the first middle vertical tube 30 are all provided with second through holes 310, and each side wall of the first middle vertical tube 30 is provided with a third through hole 300 communicating with the inner cavity of the first middle vertical tube 30. The principle of the layout of the third through holes 300 is to ensure the strength of the first middle vertical tube 30 while increasing the contact area between each side wall of the first middle vertical tube 30 and each contact surface through the third through hole 300;

[0074] ③ Install the left exterior wall panel 5 and the right exterior wall panel 50, wherein:

[0075] The top and bottom surfaces of the middle outer wall panel 4, the left outer wall panel 5, and the right outer wall panel 50 are all equipped with first assembly grooves 40 that match the transverse through-pipe 2, so that the middle outer wall panel 4, the left outer wall panel 5, and the right outer wall panel 50 can accommodate the part of the transverse through-pipe 2 protruding from the strip-shaped groove 10 through the first assembly groove 40 at the bottom, thereby making the bottom surfaces of the middle outer wall panel 4, the left outer wall panel 5, and the right outer wall panel 50 contact the top surface of the concrete floor slab 1 located below the corresponding panel.

The first end pipe 31 of the bottom vertical through pipe 3 protrudes out of this space. Preferably, the protrusion height is 1 / 2 of the height of the first end pipe 31.

[0077] Multiple first reinforcing ribs 42 are arranged vertically at intervals in the first receiving groove 41 on the left side of the right outer wall panel 50 and the first receiving groove 41 on the left side of the middle outer wall panel 4.

The top groove 54 on the top of the left tube 52 and the right tube 53 has a positioning hole 57 through it.

[0082] The bottom of both the left tube 52 and the right tube 53 is recessed and has a first bottom groove 55 that matches and engages with the first assembly groove 40 at the bottom of the first layer of the outer wall panel, so that the first assembly groove 40 and the first bottom groove 55 can accommodate the protruding part of the transverse tube 2 of the first layer relative to the strip groove 10.

[0083] Each first bottom groove 55 protrudes downward and is connected to a first insertion tube 56. A pair of first insertion tubes 56 are respectively matched with the mounting holes 20 on both sides of the transverse through tube 2, so as to be inserted into the corresponding mounting holes 20 one by one.
