Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] A new type of stair formwork, including a support frame 1, a bottom plate 2, side plates 3 and 4, and a step baffle 5, is characterized in that:

[0022] The support frame 1 is used to support the bottom plate 2 and fix the first side plate 3. The support frame 1 includes a beam 11, two support legs 12, and a fixing member 13 that can fix the first side plate 3; the beam 11 includes a left Section 111, middle section 112, right section 113, the middle section 112 is inserted in the left section 111 and the right section 113 sleeve and can be stretched, and the fixing bolts that can prevent the middle section 112 from stretching are set on the left section 111 and the right section 113 114, the two ends of the left section 111 and the right section 113 are provided with upper and lower through holes 115; the two support legs 12 are parallel to each other and vert...

Abstract

The invention discloses a novel stair formwork. The novel stair formwork comprises a supporting frame, a base plate, side plates and stepping baffles. The supporting frame can support the base plate and fix the first side plate, the height and the width can be adjusted, the application range is wide, and stability is high. The base plate is formed through splicing of a plurality of plates and can be suitable for stairs with different widths and lengths. The side plates comprise the first side plate and the second side plate and can meet the requirements for stairs without side walls and stairs with side walls. Clamping grooves are formed in the side plates, and thus the stepping baffles can be fixed conveniently and firmly. Each stepping baffle comprises a vertical plate, a horizontal plate and a reinforcing plate, strong firmness can also be achieved even if the stepping baffles are made of thin plates, and construction and mounting are facilitated. The novel stair formwork is wide in application range, high in stability, capable of being used repeatedly, free of deformation, convenient to mount and dismount, and long in service life.

Description

technical field [0001] The invention belongs to the technical field of buildings, in particular to a novel staircase formwork. Background technique [0002] Stairs are a necessary structural component of every project, and are generally made of reinforced concrete. Because reinforced concrete stairs have good load-bearing, durable and fireproof performance, and the space layout of cast-in-place reinforced concrete stairs is flexible, it is easy to meet the requirements of different buildings. , so it is widely used in construction engineering. To pour reinforced concrete stairs, it is necessary to set up various formwork according to the designed size. After the reinforced concrete is poured and solidified, the formwork is disassembled to obtain the required staircase. [0003] The existing cast-in-place concrete stair formwork has disadvantages such as waste of labor, easy deviation of size, easy deformation, difficult installation and disassembly, low reuse rate, small ap...
