Description

Technical Field

[0001] The invention belongs to the field of lamp installation, and in particular relates to a lamp barrel reserved annular groove forming part and a construction method. Background Art

[0002] When installing deep-bucket lamps on the ground in places such as airports, the lamp barrel of the deep-bucket lamp is usually buried in the ground by pouring concrete. When pouring concrete, an annular groove needs to be set between the upper edge of the lamp barrel and the concrete ground to eliminate the stress caused by the different expansion coefficients of the lamp barrel and the ground concrete. In terms of the annular groove setting, the traditional method of drilling to form a lamp pit is to form it. The specific operation method is as follows: before pouring the concrete on the ground, a lamp pit mold is embedded at the lamp installation position. After the concrete is paved, the concrete is drilled to the lamp pit mold position, and the embedded lamp pit mold is taken out to form a lamp pit. The diameter of the lamp pit mold is larger than the diameter of the lamp barrel. After the lamp barrel is installed at the lamp pit position, an annular groove is formed between the inner wall of the lamp pit and the lamp barrel. However, this lamp pit formation method has the following disadvantages:

[0003] First, the quality of lamp pit molding is poor, and boring and trimming are required, which is inefficient;

[0004] Secondly, the shape of the lamp model and its placement determine the shape of the lamp pit. The deformation of the lamp model and the tilted placement of the lamp make the lamp pit irregular, which results in poor water blocking effect after the lamp is installed and easy to leak water.

[0005] Third, drilling holes to take out molds and boring holes to trim will produce a certain amount of concrete slag, which does not meet the requirements of green and environmentally friendly construction. Summary of the Invention

[0006] The purpose of the present invention is to provide a construction method for a reserved annular groove in a lamp barrel, so as to solve the problem of large amount of secondary repair work in existing lamp pits, so that the lamp pit can be formed in one step, the construction efficiency can be improved, and the construction quality can be guaranteed.

[0007] The technical solution adopted by the present invention is as follows: a lamp barrel reserved annular groove forming part includes a body, the body including an adjustment section and a matching section along its axial direction; a slot hole is provided on the body along its axial direction, the slot hole is adapted to the outer wall of the lamp barrel and passes through at least the matching section of the body;

[0008] The main body is in a columnar shape or a frustum shape that gradually decreases from the adjusting section to the matching section along its axial direction.

[0009] Furthermore, the main body is in a frustum shape that gradually decreases from the adjustment section to the fitting section along its axial direction.

[0010] Furthermore, the adjustment section includes, along its radial direction, a connecting portion integrally connected with the matching section and a limiting portion located inside the connecting portion.

[0011] Furthermore, the limiting portion is annular.

[0012] Furthermore, a plurality of threaded holes are evenly distributed along the circumferential direction of the main body, and the threaded holes penetrate the adjustment section along the axial direction and extend to the fitting section.

[0013] Furthermore, the body is a rubber product.

[0014] The construction method of the reserved annular groove of the lamp barrel, step 1, sets the lamp barrel reserved annular groove forming part on the top of the lamp barrel;

[0015] Step 2: Apply a coating agent to the outer wall of the body of the lamp barrel with the reserved annular groove formed part;

[0016] Step 3: pouring concrete;

[0017] Step 4: Remove the lamp barrel reserved annular groove forming piece from the top of the lamp barrel to form an annular groove.

[0018] Furthermore, in step five, the annular groove is filled with silicone sealant.

[0019] Furthermore, the construction method of the reserved annular groove of the lamp barrel is characterized in that: in step four, the reserved annular groove forming part of the lamp barrel is pulled out after being threadedly connected to the threaded hole on the body of the lamp barrel reserved annular groove forming part using a pulling tool.

[0020] The beneficial effects of the present invention are as follows: the lamp barrel reserved annular groove forming part disclosed by the present invention has a simple structure, is easy to use, and has a high reuse rate.

[0021] This method allows for the removal of pre-formed annular grooves for lamp barrels without boring. This reduces drilling equipment and labor, saving costs and time, and meeting energy-saving, environmentally friendly, and green construction requirements. The concrete surrounding the annular grooves will not collapse, fall, or crack, resulting in an aesthetically pleasing finish and high visual quality, while also eliminating the need for repairs. Furthermore, the annular grooves are formed simultaneously with the pouring of the lamp barrels, further shortening the overall construction period. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In the figure, the main body 1, the adjustment section 11, the connecting portion 111, the limiting portion 112, the matching section 12, the slot hole 2, the threaded hole 3, and the lamp barrel 4. DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0028] The lamp barrel reserves an annular groove forming part, such as Figure 1 and Figure 2 As shown, it includes a body 1, which includes an adjustment section 11 and a matching section 12 along its axial direction; a slot 2 is provided on the body 1 along its axial direction, and the slot 2 is adapted to the outer wall of the lamp barrel and passes through at least the matching section 12 of the body 1;

[0029] The main body 1 is in a columnar shape or a frustum shape that gradually decreases in size from the adjusting section 11 to the fitting section along its axial direction.

[0030] The lamp barrel disclosed in the present invention has a reserved annular groove forming part, the fitting section 12 is used for installation with the lamp barrel 4, and the adjustment section 11 is used for adjusting the height difference between the surface after the concrete is poured and formed and the top surface of the lamp barrel 4. The slot hole 2 is used to be fitted on the outer wall of the lamp barrel 4 of the deep barrel lamp. The slot hole 2 is adapted to the outer wall of the lamp barrel, which means that the shape of the slot hole 2 is the same as that of the lamp barrel 4, and the size satisfies that the main body 1 can just fit into the lamp barrel 4, and there is no gap between the hole wall of the slot hole 2 and the barrel wall of the lamp barrel 4 for the poured concrete to penetrate. The outer wall of the main body 1 is the pouring surface. After the concrete is poured and solidified, in order to be able to remove the formed part, the main body 1 is cylindrical or cone-shaped that gradually shrinks along its axial direction from the adjustment section 11 to the fitting section.

[0031] In order to facilitate the smooth removal of the formed part, it is optimal that the main body 1 is in a frustum shape that gradually decreases along its axial direction from the adjusting section 11 to the fitting section.

[0032] The slot hole 2 can pass through the matching section 12 and the adjustment section 11 at the same time, but this structure requires careful observation by the staff during installation, so that the adjustment section 11 is exposed at the top of the lamp barrel 4, which is inconvenient to install. In order to avoid this problem, it is optimal that the adjustment section 11 includes a connecting portion 111 connected to the matching section 12 and a limiting portion 112 located on the inner side of the connecting portion 111 along its radial direction. At this time, the slot hole 2 is only provided in the matching section 12. The adjustment section 11 is flat and blocks the opening of the slot hole 2 adjacent to one end of the adjustment section 11. It is optimal that the limiting portion 112 is annular, that is, the limiting portion 112 is provided at the opening of the slot hole 2 adjacent to one end of the adjustment section 11, and a center hole is provided at the center of the limiting portion 112, and the aperture of the center hole is smaller than the aperture of the slot hole 2. The setting of the limiting portion 112 allows the limiting portion 112 to abut against the top of the lamp barrel 4 during installation, making installation convenient. The annular setting saves materials and improves the flexibility of the main body 1, making it easier for the main body 1 to be mounted on the lamp barrel 4.

[0033] To facilitate removal of the formed part after the concrete has solidified, preferably, several threaded holes 3 are evenly distributed along the circumference of the body 1. These threaded holes 3 extend axially through the adjustment section 11 to the mating section 12. The threaded holes 3 provide a fulcrum for removing the formed part. The number of threaded holes may be two, three, or four.

[0034] The molded part is flexible, exhibiting a certain degree of deformation and optimal recovery properties. It can be fitted onto the lamp barrel 4 while maintaining a close fit with the outer wall of the lamp barrel 4. Furthermore, it is not easily damaged or deformed during use. Furthermore, when removing the molded part, it does not damage the annular groove. Therefore, the main body 1 is made of rubber.

[0035] Construction method of reserved annular groove for lamp barrel, step 1, as Figure 3 or Figure 4 As shown, the lamp barrel reserved annular groove forming piece is sleeved on the top of the lamp barrel 4;

[0036] Step 2: Apply a coating agent to the outer wall of the body 1 of the lamp barrel with the annular groove formed part reserved therein;

[0037] Step 3: pouring concrete;

[0038] Step 4: After the concrete reaches 70% strength, the lamp barrel reserved annular groove forming piece is removed from the top of the lamp barrel 4 to form an annular groove.

[0039] The construction method of the reserved annular groove for the lamp barrel can remove the lamp barrel reserved annular groove forming part after the concrete solidifies without boring, which reduces the consumption of drilling equipment and labor, saves costs and construction period, and meets the requirements of energy conservation, environmental protection and green construction. The concrete around the annular groove will not have defects such as collapse, falling edges or cracking, and the molding is beautiful, the visual quality is good, and the repair process is saved. In addition, the formation of the annular groove is carried out simultaneously with the pouring of the lamp barrel 4, which is more conducive to shortening the overall construction period. After the lamp barrel reserved annular groove forming part is taken out, silicone sealant is immediately poured into the annular groove, which not only reduces the debris cleaning process, but also makes the silicone sealant have better adhesion.

[0040] In step 4, a pulling tool is used to threadably connect the threaded hole 3 on the body 1 of the lamp barrel reserved annular groove forming part, and then the lamp barrel reserved annular groove forming part is pulled out. The pulling tool can have a handle with a screw, etc.
