Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a bay window casting mould and a construction method. Background Art

[0002] Current high-rise building designs often feature complex facades and numerous exterior wall joints. Contemporary apartment buildings, in particular, often feature numerous bay windows. Bay windows provide ample daylight and a sense of spaciousness, broadening the interior's visual field. Consequently, more and more buildings are adopting bay windows. Bay window construction involves pouring in two or even multiple steps. First, the lower formwork is erected. Once the lower floating plate structure is formed and solidified, the lower formwork is removed. The lower floating plate is then used as support to erect the upper formwork. Concrete is then poured into the upper formwork. Once the upper floating plate is formed and solidified, the upper formwork is removed. The upper floating plate is then used as support to erect the lower formwork on the upper floor. Since concrete takes approximately 12 days to initially take shape after pouring, and approximately 28 days to fully withstand the load, the construction process is complex and slow. Summary of the Invention

[0003] The object of the present invention is to provide a bay window casting mold, which can support an upper mold body and a lower mold body located on the upper layer through precast concrete pads, thereby facilitating the continuous progress of construction and improving construction progress.

[0004] The present invention is achieved through the following technical solutions: a bay window casting mold, comprising a plurality of vertically distributed bay window casting templates, wherein the plurality of bay window casting templates are arranged one-to-one at the ends of the floor templates, the bay window casting template comprises an upper mold body, a lower mold body and a side mold body, the upper mold body and the lower mold body are both connected to the side mold body, precast concrete pads are provided in the upper mold body and the lower mold body, a first support member is provided between the precast concrete pad of the lower mold body and the upper mold body, and a second support member is provided between the precast concrete pad of the upper mold body and the lower mold body of the bay window casting template of the upper layer.

[0005] Furthermore, the first support member includes a first support rod, the bottom end of the first support rod abuts against the precast concrete pad of the lower mold body, and the top end of the first support rod is vertically provided with at least two supporting rods for supporting the upper mold body; the second support member includes a second support rod, the bottom end of the second support rod abuts against the precast concrete pad of the upper mold body, and the top end of the second support rod is provided with a top support for supporting the lower mold body.

[0006] Furthermore, the bottom of the upper mold body and the lower mold body are provided with multiple wooden planks spaced apart along their width direction. The wooden planks at the bottom of the upper mold body are placed on the top of the supporting rod and are perpendicular to the supporting rod, and the wooden planks at the bottom of the lower mold body are placed on the top support.

[0007] Furthermore, each of the upper mold body and the lower mold body is provided with at least two precast concrete pads, and each of the precast concrete pads is provided with a first support member or a second support member.

[0008] Furthermore, an oblique support rod is provided on one of the precast concrete pads located on the lower mold body, and the top end of the oblique support rod is connected to the floor steel pipe frame.

[0010] Furthermore, the tongue-and-groove step is located on a side of the upper mold body or the lower mold body away from the floor formwork.

[0011] Furthermore, the thickness of the precast concrete pad is equal to the depth of the upper mold body or the lower mold body.

[0012] The present invention also provides a construction method using the above-mentioned bay window casting mold, comprising the following steps:

[0013] S1. Build the upper formwork, lower formwork, and side formwork in sequence at the end of the floor steel pipe frame extending outside the floor formwork to form the bay window casting formwork;

[0014] S2. Place precast concrete pads in both the upper and lower mold bodies, install a first support member between the precast concrete pad in the lower mold body and the upper mold body, and install a second support member between the precast concrete pad in the upper mold body and the lower mold body of the upper bay window casting formwork;

[0015] S3. Pour concrete into the multi-layer bay window casting formwork layer by layer. After pouring the lower mold body of each layer of bay window casting formwork, the first support member can support the upper mold body. At this time, even if the concrete in the lower mold body has not yet hardened, the precast concrete pads in the lower mold body can bear the weight of the concrete in the upper mold body transferred from the first support member.

[0019] 1. The present invention supports the upper mold body and the lower mold body located on the upper layer through precast concrete pads. When the poured concrete is not yet able to bear the load, the precast concrete pads can bear the weight of the upper mold body and the lower mold body located on the upper layer in advance, so that the pouring operation can be carried out continuously, thereby facilitating the continuous progress of construction and improving the construction progress.

[0020] 2. The present invention provides tongue-and-groove steps on the bottom plates of the upper mold body and the lower mold body, so that the bay window casting body formed by solidification of concrete has a tongue-and-groove groove. The setting of the tongue-and-groove groove makes the side of the bay window casting body facing the inside of the building floor higher than the side of the bay window casting body facing the outside of the building floor. After the window is installed, the step of plastering the bay window is eliminated, and the effect of preventing rainwater leakage is improved. BRIEF DESCRIPTION OF THE DRAWINGS
