Description

Technical Field

[0001] The invention relates to the technical field of prefabricated equipment foundation construction, in particular to a prefabricated equipment foundation construction method. Background Art

[0002] With the development of electrical and automation technology, more and more equipment is used in various industries. The equipment foundation structure is now very common. The equipment foundation plays the role of supporting and fixing equipment, transferring loads, and reducing vibration and noise. Its construction accuracy is very important.

[0003] The traditional equipment foundation construction method is to use the method of tying reinforcement together with the pedestal and casting the formwork together or separately. This method takes a long time in terms of construction cycle, and the casting effect of the equipment foundation surface is poor. At the same time, the installation accuracy of the embedded parts is easily affected by the pouring and vibration of concrete, resulting in quality problems such as levelness and plane positioning deviation, which are difficult to correct once they occur. Summary of the invention

[0004] The present invention aims to solve the above-mentioned problem, thereby providing a prefabricated equipment foundation construction method.

[0005] The present invention solves the above-mentioned problem by adopting the following technical solution: A prefabricated equipment foundation construction method comprises the following steps: S1: Lay the bottom template on the flat ground. The top surface of the bottom template is used as the forming surface of the top surface of the equipment foundation. The embedded parts are inverted at the corresponding position of the bottom template according to the drawing; S2: Tie the equipment foundation steel bars above the bottom formwork; S3: Support the side formwork of the equipment foundation and strengthen it firmly; S4: Pour the equipment foundation concrete. At the end of pouring, make a gentle slope around the center line of the equipment foundation plane to ensure that the concrete is poured densely without bubbles; S5: After the equipment foundation concrete is formed, remove the side formwork; S6: Turn over the prefabricated equipment foundation, place it on the pre-prepared support, and remove the bottom formwork; S7: Install the positioning plate on the main reinforcement of the foundation in advance, use the total station or laser to position and support the prefabricated equipment foundation, use the lifting equipment to hoist the prefabricated equipment foundation on the positioning plate, check the foundation elevation and embedded parts positioning, and fix it after adjustment; S8: Pour the foundation concrete and the installation is completed.

[0006] Furthermore, in S1, the installation position of the embedded part is determined by marking and positioning, and after the embedded part is installed at the designated position, small nails are nailed around the embedded part plate for temporary reinforcement to prevent the embedded part position from shifting during the pouring of the equipment foundation concrete.

[0007] Furthermore, in S3, the height of the side formwork is 8 mm -10 mm higher than the height of the equipment foundation, so that the height of the prefabricated equipment foundation after pouring is higher than the design elevation; ensuring subsequent close contact with the foundation concrete.

[0008] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features: Compared with the traditional method, the prefabricated equipment foundation construction method described in the present invention can effectively shorten the construction period by prefabricating the equipment foundation in advance, change the on-site construction content into production plant construction, and create a more favorable construction environment; the top surface of the prefabricated equipment foundation is formed by a template, which is flatter and smoother than the top surface of directly cast and solidified concrete, thereby improving the construction quality; the embedded parts are temporarily fixed to the template, which can prevent the position of the embedded parts from shifting during the pouring of the equipment foundation concrete, ensure installation accuracy, and reduce the subsequent secondary finishing process.
