Problems solved by technology

[0002] In the foundation construction of residential projects, the cap platform is generally constructed with brick tire formwork, which has many construction procedures. Before the construction of brick tire formwork and rotary tire formwork, the lateral extrusion capacity of the retaining soil is weak before the masonry mortar reaches its strength. ; Qidong Zhongbang Shanghai City Phase II, Lot C, Lot 1 project is developed and constructed by Country Garden, and the site construction period is tight. The progress is slow, and many places are squeezed and deformed by the soil, which does not meet the requirements of construction quality and progress.
[0003] Therefore there are above-mentioned inconveniences and problems in the known platform brick tire mold

Embodiment 1

[0030] The production sequence of the cap steel mold of the present invention is: blanking according to the design size of the on-site drawings → zero, component processing → assembly, assembly welding → calibration → process inspection → painting → marking → final inspection → storage → on-site installation.

[0031] The manufacturing method of cap steel mold of the present invention comprises the following steps:

[0032] a. The steel formwork of the platform is processed and manufactured according to the size of the platform and the water collection well marked in the construction drawing of the design structure. The steel used should have a material certificate and meet the relevant provisions of the current national standards.

[0033] see now figure 1 , figure 1 It is a structural schematic diagram of the cap steel formwork of the embodiment of the present invention. As shown in the figure, the bearing platform is a steel plate frame surrounded by upright wall plates w...

Embodiment 2

[0041] figure 2 It is a schematic plan view of the installation of the cap steel mold of the embodiment of the present invention, image 3 for figure 2 Sectional view of A-A in Fig. The installation of thin steel plate welded shaped steel bearing platform steel mold of the present invention comprises the following steps:

[0042] (1) The installation of the steel formwork for the platform requires the cooperation of a small excavator. The construction personnel sprinkle the axis and the sidelines of the platform and the water collection well with lime on the soil layer of the foundation pit. The small excavator digs out the position of the steel formwork and mechanically excavates The parts that are not in place need to be cleaned manually.

[0043] (2) After the excavation of the cap steel form is completed, install the cap steel form. During the installation process, the construction technicians use a level to control the elevation, and strictly control the height and t...

Abstract

The invention discloses a production method for a steel die for a bearing platform. The production method for the steel die for the bearing platform is characterized by comprising the following steps:a. the steel die for the bearing platform is machined and produced according to the dimensions of the bearing platform and a water-collecting well which are marked in a construction drawing for a design structure; b. the blanking dimensions of a wall plate and a flanging need to be accurate; c. the wall plate needs to be levelled and straightened by a steel ruler before assembly welding; d. the assembly welding for the wall plate needs to be carried out on a special fixture platform; e. deformation after the assembly welding for the wall plate needs to be corrected; f. after welding for a steel plate frame is completed, a support rib is welded at the middle in the steel plate frame through a steel bar support; and g. after the first batch of the steel dies for the bearing platforms are produced through welding, large-scale subsequent machining can be carried out after examination is passed. The production method for the steel die for the bearing platform has the following advantages:the steel die for the bearing platform is simple in structure and convenient to produce; and the construction time is greatly shortened, so that the construction efficiency is obviously increased, andthe engineering cost is lowered.

Description

technical field [0001] The invention relates to a steel mold for replacing a traditional brick cap in foundation construction, in particular to a manufacturing method for a cap steel mold. Background technique [0002] In the foundation construction of residential projects, the cap platform is generally constructed with brick tire formwork, which has many construction procedures. Before the construction of brick tire formwork and rotary tire formwork, the lateral extrusion capacity of the retaining soil is weak before the masonry mortar reaches its strength. ; Qidong Zhongbang Shanghai City Phase II, Lot C, Lot 1 project is developed and constructed by Country Garden, and the site construction period is tight. The construction progress was slow, and many places were squeezed and deformed by the soil, which did not meet the requirements of construction quality and progress. [0003] Therefore there are above-mentioned inconveniences and problems in the known platform brick t...
