Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and particularly relates to a waterstop formwork device and a construction method thereof. Background Art

[0002] The traditional construction method of the water stop sill in the settlement part of the bathroom is to cast it twice after the main structure is completed, that is, first cast the floor beams and frame columns, then set the water stop sill template at the edge of the settlement part of the bathroom, and finally cast the water stop sill in the settlement part. However, the water stop sill is cast later, and there are certain leakage risks at the junction with the original concrete floor slab and the junction with the frame column.

[0003] In order to solve the leakage risk at the junction with the concrete floor, a one-time formed water stop is used. However, when the water stop is connected to the frame column, in order to ensure the integrity of the frame column formwork system, a wider construction joint is often left between the water stop and the frame column during the formwork process, which not only affects the visual quality but also poses a leakage risk. In addition, in the current building structure design, there is often a situation where the concrete strength of the wall column and the beam slab is different. During the construction process, the wall column concrete must be poured first. At the same time, considering the existence of the longitudinal steel bars of the wall column, the retention method of the construction joint at the junction of these one-time formed water stops and frame columns has a great impact. Summary of the invention

[0004] The purpose of the present invention is to provide a waterstop formwork device and a construction method thereof which can avoid the occurrence of a wide construction joint at the junction of the waterstop and the frame column.

[0005] To this end, the first technical solution of the present invention is: a waterstop formwork device, characterized in that: it includes a formwork body, the formwork body is composed of two connecting plates, one end of the two connecting plates are connected to each other through an acute angle, and the radial cross-section is in the shape of a "〉", and the other ends of the two connecting plates are bent outward to form a first side panel, and the two first side panels are located on the same plane; the first side panel is bent in the direction of the acute angle to form a second side panel, the first side panel and the second side panel form a positioning frame, and the first side panel and the second side panel are perpendicular to each other, and the two second side panels are parallel to each other; a support rod is also provided between the two connecting plates, and support blocks are provided on the opposite sides of the two connecting plates, and the two ends of the support rod are respectively installed on the support blocks on both sides.

[0006] Preferably, an opening is provided at the lower end of the connection of the two connecting plates, and a water-stop steel plate is provided in the opening.

[0007] The positioning frames on both sides of the formwork body are in the shape of "[", which can be used to position the water stop sill formwork; the support rod arranged between the two connecting plates is a detachable structure, and the two ends of the support rod are buckled on the support blocks of the connecting plates, which is easy to install and disassemble, and can effectively prevent deformation of the two sides of the formwork body.

[0008] The second technical solution of the present invention is: a construction method of a water stop formwork device, comprising the following steps:

[0009] 1) The formwork device is placed at the junction of the water stop sill and the frame column. The two water stop sill templates are placed on the positioning frames on both sides of the formwork device, fixed with nails, and a water stop steel plate is placed at the opening in the middle of the formwork device;

[0010] 2) Pour concrete between the two waterstop formworks. When the concrete pouring of the waterstop reaches the designed strength, remove the formwork device and the waterstop formwork. When the “〉”-shaped connecting plate on the formwork device is removed, a triangular notch is left at one end of the waterstop facing the frame column.

[0011] 3) Start to support the frame column formwork. Set an opening in the frame column formwork opposite to the waterstop. The size of the opening is the same as that of the waterstop. The position of the opening is opposite to the notch on the waterstop. Add a cover plate on the waterstop to prevent concrete from leaking from the notch during pouring.

[0012] The present invention utilizes a formwork device with a “〉”-shaped structure to cast a waterstop with a triangular notch, and then casts a frame column and the notch as a whole. After casting, the concrete at the notch can connect the frame column and the pre-cast waterstop into one, so that the waterstop and the frame column are closely connected without a construction joint, thereby avoiding leakage hazards and ensuring construction quality.

DETAILED DESCRIPTION

[0020] See the attached drawings. The waterstop formwork device 1 described in this embodiment includes a formwork body, which is composed of two connecting plates 11. One end of the two connecting plates 11 is connected to each other through an acute angle, and the radial cross-section is in the shape of a "〉" character. The other ends of the two connecting plates are bent outward to form a first side plate 12, and the two first side plates 12 are located on the same plane; the first side plate 12 is bent in the direction of the acute angle to form a second side plate 13, and the first side plate and the second side plate form a positioning frame 14, and the first side plate and the second side plate are perpendicular to each other, and the two second side plates are parallel to each other. The positioning frames 14 on both sides of the formwork body are in the shape of "[", which can be used to position the waterstop formwork 4; a support rod 2 is also provided between the two connecting plates 11, and support blocks 15 are provided on the opposite sides of the two connecting plates, and the two ends of the support rod 2 are respectively installed on the support blocks 15 on both sides. The support rod 2 is a detachable structure, and the two ends of the support rod are buckled on the support blocks of the connecting plate, which is convenient for installation and disassembly, and can effectively prevent the deformation of the two sides of the formwork body. The upper end of the connection of the two connecting plates 11 is an acute angle structure, and the lower end is provided with an opening 16 in the vertical direction, and a water-stop steel plate 3 is provided in the opening.

[0021] During construction:

[0022] 1) The formwork device 1 is placed at the junction of the water stop sill and the frame column, and two water stop sill templates 4 are placed on the positioning frames 14 on both sides of the formwork device, fixed with nails, and a water stop steel plate 3 is placed at the opening in the middle of the formwork device;

[0023] 2) pouring concrete between the two waterstop formworks 4. When the concrete pouring of the waterstop 7 reaches the designed strength, the formwork device 1 and the waterstop formwork 4 are removed. When the “〉”-shaped connecting plate on the formwork device 1 is removed, a triangular notch 71 is left at one end of the waterstop 7 facing the frame column.

[0024] 3) Start to support the frame column template 6. The frame column template 6 has a hole at the position opposite to the water stop sill. The hole size is the same as the water stop sill 7. The hole and the notch on the water stop sill are opposite to each other. A cover plate 8 is added to the water stop sill 7 to prevent concrete from leaking from the notch during pouring. During pouring, the concrete in the frame column template can flow from the hole to the notch, fill the notch with concrete, connect the already poured water stop sill, and pour the frame column normally at the same time, completing the seamless construction of the frame column and the water stop sill.
