Problems solved by technology

[0003] 1. The disadvantage of construction technology without surface formwork is that this technology can only be applied to sloped roofs with small slopes (the slope of sloped roofs is less than 15 degrees). The main problem is that the construction method of pumping concrete is generally used for roof concrete pouring. When using the construction technology without supporting the surface formwork, the slump of the roof concrete is required to be small, which will be beneficial to the forming of the roof concrete. However, the slump of the concrete is too small to meet the requirements of pumping.
[0004] 2. The disadvantages of the construction technology of the supporting surface formwork are: it is difficult to tamp and vibrate, and it is easy to form surface processing defects after tamping

Embodiment 1

[0033] Such as Figure 1~5 Among them, a slope roof concrete construction device comprises a lower layer of steel mesh 9 and an upper layer of steel mesh 8 arranged along the slope roof, and a plurality of concrete pads 12 are arranged on the upper layer of steel mesh 8, and the concrete pad 12 is provided with There is a formwork 1, and the tie rods 10 are connected to the upper reinforcement mesh sheet 8 and the lower reinforcement mesh sheet 9. The ends of the tie rods 10 pass through the formwork 1 and are connected to the nuts 7. A plurality of concrete vibrating holes 2 are arranged on the formwork 1, and there are also The vibrating hole filling 3 installed in the concrete vibrating hole 2;

[0034] In the vibrating hole filling 3, the bottom plate 32 is provided with a filling plate 31, and the diameter of the filling plate 31 is the same as that of the concrete vibrating hole 2. The same at this time means that the filling plate 31 can just be placed in the concrete v...

Embodiment 2

[0040] A method for concrete construction of a slope roof using the above structure, comprising the following steps:

[0041] 1. According to the angle а of the slope roof, set the lower steel mesh 9, the upper steel mesh 8 and the tie rods 10;

[0042] Two, a plurality of concrete pads 12 are set on the upper steel mesh sheet 8, and the slope formed by the concrete pads 12 is the same as the slope roof angle а;

[0043] 3. According to the radius of action of the concrete vibrating rod, a plurality of concrete vibrating holes 2 are opened on the formwork 1. The diameter of the concrete vibrating hole 2 is greater than the diameter of the concrete vibrating rod; the distance between the concrete vibrating holes 2 and the hole size The size needs to meet the vibration needs of concrete.

[0044] 4. Lay the prepared template 1 on the concrete pad 12, set the wooden frame 4 on the back of the template 1 as the vertical keel at the bottom, and the steel pipe 5 as the horizontal k...

Abstract

Provided are a slope roof concrete construction device and method. A lower layer steel rib net piece and an upper layer steel rib net piece which are arranged along a slope roof are included. The upper layer steel rib net piece is provided with a plurality of concrete cushion blocks which are provided with formworks. A pulling rod is connected with the upper layer steel rib net piece and the lower layer steel rib net piece. The end of the pulling rod penetrates through the formworks and is connected with a nut. A plurality of concrete vibration holes are formed in the formworks, and vibration hole padding plugs arranged in the concrete vibration holes are further arranged. In the vibration hole padding plugs, padding plug plates are arranged on bottom plates, the padding plug plates and the concrete vibration holes are the same in diameter, the padding plug plates and the formworks are the same in thickness, and the lengths of the bottom plates in at least one direction are larger than the diameters of the padding plates. The compactness of concrete is guaranteed by forming the concrete vibration holes. Through the arranged vibration hole padding plugs, engineering waste formworks can be fully used, the appearance construction quality of concrete can be improved, cost of later concrete protrusion processing is saved, and the site construction progress is accelerated.

Description

technical field [0001] The invention relates to slope roof concrete construction, in particular to a slope roof concrete construction device and method. Background technique [0002] The existing concrete construction techniques for slope roofs mainly include two technologies: unsupported surface formwork and supported surface formwork. [0003] 1. The disadvantage of construction technology without surface formwork is that this technology can only be applied to sloped roofs with small slopes (the slope of sloped roofs is less than 15 degrees). The main problem is that the construction method of pumping concrete is generally used for roof concrete pouring. When the construction technology without surface formwork is adopted, the slump of the roof concrete is required to be small, which will be beneficial to the forming of the roof concrete. However, the slump of the concrete is too small to meet the requirements of pumping. [0004] 2. The disadvantages of the construction ...
