Description

TECHNICAL FIELD

[0001] The present application relates to the field of construction, in particular to a construction method of a bay window. BACKGROUND

[0002] The building bay window usually has two bay window panels, an upper bay window panel and a lower bay window panel. The upper bay window panel and the lower bay window panel are horizontally protruding structures, and the space between the upper bay window panel and the lower bay window panel of the room at the same floor is used for installing the window frame and glass. From the perspective of the room, the vertical wall structure between the upper bay window panel and the roof is usually referred to as a beam, and the vertical wall structure between the lower bay window panel and the floor is usually referred to as a column. During construction, the beam and the upper bay window panel are cast together, the column and the lower bay window panel are cast together, and the beam and the column are cast separately, which needs to be completed in two construction periods. Among them, the beam is cast with the building structure below the floor level, and the column is cast with the building structure above the floor level.

[0003] During casting, formwork needs to be used. At the joint between the upper and lower two floors that need to be cast in sequence, a K plate (also formwork) is usually used. The K plate is used to connect the upper and lower floors, with a part above the floor level and a part below the floor level. The K plate below the floor level is used as formwork. The K plate above the floor level is used for positioning and preventing leakage of the upper layer during casting. In building construction, an aluminum K plate is usually used, and its size is designed with a certain standard, and its height is usually 300 mm.

[0004] When the climbing frame machine position is set at the building bay window, since there is the outwardly protruding bay window panel, a transition piece (commonly known as a heightening piece) needs to be used to connect the attached wall support of the climbing frame machine position and the building main body.

[0005] The traditional heightening piece has a relatively large size, and needs to occupy a large space during installation. It is installed on the beam and column of the upper and lower floors, i.e., a part is installed on the column above the floor level, and a part is installed on the beam below the floor level. Since the beam and the column are cast separately, when the heightening piece needs to be installed, the column has not been cast, and the formwork of the column needs to be fixed by the K plate, and the height of the K plate is 300 mm, which will affect the installation of the heightening piece. The heightening piece needs to be installed after the column is cast and the K plate and the column formwork are removed. Since the heightening piece is installed late, it cannot guarantee that an attached wall support is installed on each built floor, which not only affects the safety of the climbing frame, but also causes the climbing frame to be not lifted in time, thereby affecting the construction efficiency. SUMMARY

Detailed Implementation Methods

[0033] The following embodiments are further explanations and supplements to the present invention and do not constitute any limitation on the present invention.

[0034] like Figures 1-3 As shown, the construction method for the climbing frame at the bay window of the present invention includes the following steps:

[0035] S1. A beam formwork 20 and a 150mm high K plate 30 are erected at the position of the exterior wall between the upper bay window slab 10 to be poured and the floor level. The top of the K plate 30 is above the floor level, and the bottom of the K plate 30 is below the floor level. The beam formwork 20 is located between the K plate 30 and the upper bay window slab 10 to be poured.

[0036] S2. Pour the floor below the floor level, and pour the upper bay window slab 10 and the beam 40 from the upper bay window slab 10 to the roof.

[0037] S3. Keep K plate 30 intact, and remove the beam formwork 20 and the formwork at the inner wall position of beam 40;

[0038] S4. Install the heightening component 50 at the outer wall position of the beam 40;

[0039] S5. Connect the wall-mounted support 60 of the climbing scaffold to the extension piece 50.

[0040] In step S1, the K-plate 30 is used to support the formwork 80 and the beam formwork 20. It can be installed between the building walls to be poured in two separate sections using known methods. The K-plate 30 is made of aluminum and has a height of 150mm. During installation, the top of the K-plate 30 is 50mm above the floor level, and the bottom 100mm of the K-plate 30 is below the floor level.

[0041] The dimensions of beam 40 vary depending on the building unit. Based on the height of beam 40 and the height of K-slab 30, the required number and dimensions of beam formwork 20 can be calculated. The dimensions of the beam formwork 20 are not limited and can be selected according to actual needs. The installation of the beam formwork 20 can refer to known techniques, and it is located between K-slab 30 and the upper bay window slab 10 to be poured.

[0042] To complete the pouring of the next floor at the next floor level, the required formwork is not only the K-slab 30 and beam formwork 20, but also the formwork at the interior wall position and other positions. The installation and dismantling of these formworks are no different from the existing process, and the present invention does not limit them.

[0043] When the formwork of the floor level of the next floor is set up, the pouring of the floor level of the next floor can be performed, so as to pour the upper balcony plate 10 and the beam 40 from the upper balcony plate 10 to the roof.

[0044] In step S2, the pouring method can refer to the known technology, and the embodiment does not limit it.

[0045] When the floor level of the next floor is poured, the formwork can be removed. When the formwork is removed, the K plate 30 is not removed, and the formwork at other positions can be removed, including but not limited to the beam formwork 20 and the corresponding formwork at the inner wall position of the beam 40.

[0046] When the beam formwork 20 and the formwork at the inner wall position of the beam 40 are removed, the through-wall bolt can be installed on the beam 40 to fix the heightening piece 50.

[0047] The heightening piece 50 is redesigned in the application, so that the height dimension is improved and can be installed on the beam 40. In the application, the height of the end of the heightening piece 50 installed on the beam 40 is less than 300 mm.

[0048] In addition, the height dimension of the K plate 30 is reduced, so that the wall between the K plate 30 and the upper balcony plate 10 is sufficient to install the heightening piece 50. Therefore, when the heightening piece 50 is installed, whether the vertical column 70 of the floor level of the next floor is poured or not, the heightening piece 50 can be installed after the pouring of the beam 40 is completed, so that the climbing frame can be connected to the wall without waiting for the pouring of the vertical column 70 to complete the second construction period, and the construction efficiency is improved.

[0049] As shown in Figure 4 The heightening piece 50 includes a first connecting plate 51, a second connecting plate 52 and a connecting assembly.
