Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a construction method for melting ice and snow in a combined wooden formwork during winter construction. Background Art

[0002] Hot water is a common method used in winter construction projects to melt snow and ice during combined timber formwork construction. This method uses instantaneous high temperatures to melt snow within the formwork where manual cleaning is impossible, and then pumps out the accumulated water. This method has the advantage of rapid snowmelt, allowing for quicker progress to the next construction step. However, snow removal is difficult, and if accumulated water is not removed, it can freeze at low temperatures, hindering the next concrete pour. Summary of the Invention

[0003] In response to the above problems, an embodiment of the present invention provides a construction method for melting ice and snow in a combined wooden formwork during winter construction.

[0004] An embodiment of the present invention provides a method for melting ice and snow in a combined wooden formwork for winter construction, comprising:

[0005] When tying the wall reinforcement, a fixed bracket is set at intervals around the wall at the lower part of the wall reinforcement, and a ring-shaped sleeve is set on the fixed bracket;

[0006] Set up wooden formwork outside the wall reinforcement, and open a square hole at the bottom of the corner of the wooden formwork. Cut the sleeve relative to the square hole along the cross section.

[0007] Use a wire guide to lead the electric heating sheet from one end of the casing through the square hole and then lead it back to the square hole from the other end;

[0008] The electric heating tape is used to heat the ice and snow on the outside of the casing, and the melted snow water is discharged from the wooden formwork through the square holes;

[0009] Remove the electric heating tape before pouring the wall and use wood chips to tightly seal the square hole.

[0010] Compared with the prior art, the beneficial effects of the present invention are: the installation of the plastic sleeve and the threading of the electric heating tape are relatively simple, and do not require complicated tools and equipment; the plastic sleeve can effectively protect the electric heating tape from being squeezed and damaged and create a water-free environment in the pipe, avoiding the risk of short circuit when power is turned on; the electric heating tape is small in size and has good flexibility, and can pass through narrow areas; the thermal efficiency is relatively high, and it can heat evenly, saving energy; it can be reused, avoiding secondary freezing after rain and snow melt in the template; the electric heating tape can be reused, which is more economical and practical.

[0011] Optionally, the distance between the sleeve and the concrete base plate is no more than 50 mm.

[0012] Optionally, the fixing bracket includes a clamping rod with hook-shaped ends and fixing rods arranged in parallel on the clamping rod; the spacing between the fixing rods is adapted to the diameter of the sleeve.

[0013] Optionally, one of the hooks at both ends of the clamping rod is in a right-angle shape, and the other is in an acute-angle shape. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0022] See also Figure 1 The embodiment of the present invention provides a method for melting ice and snow in a combined wooden formwork for winter construction, comprising:

[0023] Step 1: When tying the wall reinforcement, set a fixed bracket around the wall at intervals below the wall reinforcement, and set a ring-shaped sleeve on the fixed bracket. Figure 2 shown.

[0024] During implementation, sleeve 2 uses a φ30 plastic pipe, and fixed brackets are added every three meters to constrain the sleeve. The sleeve is no more than 50 mm away from the concrete base plate. During construction, branch pipes and arc-shaped double-pass sleeves can be spliced to be laid around the wall at the bottom of the wall reinforcement.

[0025] In practice, the fixing bracket consists of a hooked clamping rod with two ends, and a parallel fixing rod mounted on the clamping rod. The spacing between the fixing rods is adapted to the diameter of the casing. One of the hooks on each end of the clamping rod is at a right angle, while the other is at an acute angle. During use, the acute-angled end hooks onto the wall reinforcement, and the other right-angled end presses down to secure the fixing bracket to the wall reinforcement. This simple structure makes installation easy.

[0026] Step 2: Set up wooden formwork outside the wall reinforcement, and open a square hole at the bottom of the corner of the wooden formwork that has been set up. Cut the sleeve relative to the square hole along the cross section. Figure 4 shown.

[0027] In practice, the square hole size is 100mm*100mm.

[0028] Step 3: Use a wire guide to lead the electric heating wire from one end of the casing through the square hole and then lead it back to the square hole from the other end.

[0029] Step 4: Use the electric heating tape to melt the ice and snow on the outside of the casing, and drain the melted snow water out of the wooden formwork through the square holes.

[0030] Step 5: Remove the heating cable before pouring the wall, and use wood chips to seal the square hole tightly. Figure 3 shown.

[0031] In practice, the size of the wood chip is larger than the size of the square hole, which may be 150 mm*150 mm.

[0032] According to the solution provided by the embodiment of the present invention, the installation of the plastic sleeve and the threading of the electric heating tape are relatively simple, and do not require complicated tools and equipment; the plastic sleeve can effectively protect the electric heating tape from being squeezed and damaged and create a water-free environment in the pipe, avoiding the risk of short circuit when power is turned on; the electric heating tape is small in size and has good flexibility, and can pass through narrow spaces; it has a relatively high thermal efficiency, can heat evenly, and saves energy; it is reusable, avoiding secondary freezing after rain and snow melt in the template; the electric heating tape can be reused, which is more economical and practical.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
