Embodiment Construction
[0038] The present invention is further illustrated by specific examples below.
[0039] like figure 1 As shown in the figure, a rapid construction method for a prefabricated tile tire mold includes a cushion (1), a prefabricated board (2), a gusset (3), a U-shaped card (4), and an adhesive (5). Methods include:
[0040] Step 1. During the construction of the foundation pit, after the excavation of the earthwork in the pit is completed, the cushion (1) is quickly poured;
[0041] Step 2. Position and pay out the line, and preliminarily determine the installation position of the prefabricated board (2) in the foundation pit;
[0042] Step 3. Lay the prefabricated board (2), and apply 20mm thick 1:2 special adhesive (5) to the connection between the prefabricated board (2) and the cushion (1);
[0043] Step 4. Use U-shaped steel clips (4) to fix the upper and lower inner corners of the brick tire membrane, and place a U-shaped steel clip (4) every 1.5m at the junction of the ...

The invention relates to a rapid construction method of a prefabricated slab brick moulding bed. Which comprises a cushion layer (1), a prefabricated slab (2), an angle brace (3), a U-shaped clamp (4) and an adhesive (5), and is characterized in that the rapid construction method comprises the steps that in the foundation pit construction process, after pit-in-pit earth excavation is completed, the cushion layer (1) is rapidly poured; positioning and paying off are conducted, and the installation position of the prefabricated slab (2) in the foundation pit is preliminarily determined; laying a prefabricated slab (2), and smearing a 1: 2 special cementing agent (5) with the thickness of 20 mm at the joint of the prefabricated slab (2) and the cushion layer (1); the upper internal corner and the lower internal corner of the brick blank film are fixed through U-shaped steel clamps (4), and the U-shaped steel clamps (4) are placed at the joint of the plate and the cushion layer every 1.5 m for fixing; the steps are repeated until the installation is performed to the required height; the corner positions are fixed through angle braces (3). By the adoption of the construction method, the basement construction period can be obviously shortened, management cost, machine renting and using cost and the like are reduced, and engineering cost is reduced.
Description
technical field [0001] The invention relates to the technical field of construction of deep underground foundations of buildings, in particular to a rapid construction method of a prefabricated slab brick tire mold. Background technique [0002] With the development of the economic level and the advancement of construction technology, large-scale and super high-rise buildings have emerged in large numbers, and the foundation pit engineering presents "tight" (compact site), "near" (close engineering distance), "deep" (large excavation depth) ), "large" (large scale and size), etc. The deep foundation construction is an extremely important link in the construction of large and high-rise buildings, and the deep foundation pit supporting structure technology is undoubtedly the key to ensuring the smooth construction of deep foundations. Deep foundation pit support structure. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the above-menti...
