Description

Technical Field

[0001] The utility model relates to the technical field of well steel templates, in particular to an improved sewage inspection well steel template. Background Art

[0002] Well steel formwork is a mold used in the construction industry. It is usually used to make manhole covers or other formed concrete products. The use of well steel formwork can improve construction efficiency because it is durable and stable and can effectively maintain the shape and size of the formwork during use.

[0003] Traditional formwork uses customized curved plywood as the inner and outer formwork of the inspection well. Plywood has the advantages of being light and easy to install during use.

[0004] However, its turnover rate is not high. It is easy to deform after repeated use, making the edges and corners of the template uneven. At the same time, the surface is greatly worn, and the template joints are prone to misalignment during use. It is necessary to replace a new template after a certain number of uses, which is very expensive. Therefore, an improved sewage inspection well steel template is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an improved sewage inspection well steel template, which solves the problems of low turnover rate, deformation after multiple uses, uneven edges and corners of the template, large surface wear, and misalignment at the template joints during use, requiring replacement of new templates after a certain number of uses, which is costly.

[0006] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: an improved sewage inspection well steel template, including an inner template, an outer template and a trapezoidal template, the inner template is composed of six arc templates of the same size, the number of the trapezoidal templates is three, the outer template is composed of six semicircular templates of the same size, the inner sides of the arc template and the trapezoidal template are each provided with a first threaded hole, the internal threads of the first threaded hole are connected to a first fixing bolt, the front and back sides of the semicircular template are each provided with a second threaded hole, the internal threads of the second threaded hole are connected to a second fixing bolt, the top and bottom of the arc template and the semicircular template are each provided with a third threaded hole, the internal threads of the third threaded hole are connected to a third fixing bolt.

[0007] Furthermore, a fixing frame is fixedly connected to the left and right sides of the outer template, and a connecting support plate is hingedly connected to the inner side of the fixing frame.

[0008] Furthermore, positioning threaded holes are provided on the sides of the outer template and the connecting support plate, and positioning bolts are connected to the internal threads of the positioning threaded holes.

[0009] Furthermore, the outer side of the inner template and the inner side of the outer template are both fixedly connected with reinforcement rings, and the top and bottom of the reinforcement rings are both fixedly connected with reinforcement strips.

[0010] Furthermore, the curvature of the arc-shaped template is 165°, and the curvature of the trapezoidal template is 30°.

[0011] Furthermore, the thicknesses of the inner template, the outer template and the trapezoidal template are all 6 mm, and the inner diameter of the outer template is larger than the inner diameter of the inner template.

[0012] Furthermore, the inner formwork, outer formwork and trapezoidal formwork are all made of steel plates.

[0013] Compared with the prior art, the utility model provides an improved sewage inspection well steel template, which has the following beneficial effects:

[0014] 1. The improved sewage inspection well steel formwork can effectively save labor through the cooperation of inner formwork, outer formwork and trapezoidal formwork. At the same time, it makes the assembly of the formwork relatively simple, and the formwork can be quickly installed and fixed, thereby achieving the effect of improving turnover rate. Compared with traditional wooden formwork, steel formwork is used more frequently and has a higher residual value. Wooden formwork has almost no residual value after the completion of the project, while this formwork is made of 6mm thick steel plate, which still has a high residual value after completion, has high economic benefits, and saves formwork support materials. Compared with wooden formwork, which requires internal and external support materials, this formwork eliminates the additional support materials for internal and external formworks, saving construction costs.

[0015] 2. The improved sewage inspection well steel formwork, through the cooperation of the fixing frame, the connecting support plate, the positioning threaded holes and the positioning bolts, when the installation of this formwork is completed, the staff can pull out the connecting support plates located on the left and right sides of the outer formwork and close to the ground, so that the bottom end of the plates rests against the ground, thereby playing a supporting effect and reducing the probability of tipping. At the same time, the staff installs the positioning bolts into the inside of the positioning threaded holes of the outer formwork and the connecting support plate to enhance the stability of the outer formwork and other outer formworks.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0023] See also Figure 1-3 The improved sewage inspection well steel template in this embodiment includes an inner template 1, an outer template 2 and a trapezoidal template 3. The inner template 1 is composed of six arc templates 101 of the same size, the number of trapezoidal templates 3 is three, and the outer template 2 is composed of six semicircular templates 201 of the same size. The inner sides of the arc template 101 and the trapezoidal template 3 are both provided with a first threaded hole 4, and the internal threads of the first threaded hole 4 are connected with a first fixing bolt 5. The front and back sides of the semicircular template 201 are both provided with a second threaded hole 6, and the internal threads of the second threaded hole 6 are connected with a second fixing bolt 7. The top and bottom of the arc template 101 and the semicircular template 201 are both provided with a third threaded hole 8, and the internal threads of the third threaded hole 8 are connected with a third fixing bolt 9. Through the cooperation of the inner template 1, the outer template 2 and the trapezoidal template 3, labor can be effectively saved. At the same time, the assembly of the template is relatively simple, and the template can be quickly installed and fixed, wherein the effect of improving the turnover rate is achieved. Compared with the traditional wooden template, the steel template has a higher number of uses.

[0024] In addition, the residual value is higher. The wooden formwork has almost no residual value after the completion of the project, while this formwork is made of 6mm thick steel plate, which still has a high residual value after completion, has higher economic benefits, and saves formwork support materials. Compared with the wooden formwork that requires internal and external support materials, this formwork eliminates the additional support materials for internal and external formworks, saving construction costs.

[0025] The arc angle of the arc template 101 is 165°, and the arc angle of the trapezoidal template 3 is 30°.

[0026] It should be noted that the thickness of the inner template 1, the outer template 2 and the trapezoidal template 3 are all 6 mm, the inner diameter of the outer template 2 is larger than the inner diameter of the inner template 1, and the inner template 1, the outer template 2 and the trapezoidal template 3 are all steel plates.

[0027] Embodiment 2:

[0028] See also Figure 1 , Figure 2 and Figure 4 On the basis of the first embodiment, the left and right sides of the outer template 2 are fixedly connected with a fixing frame 10, and the inner side of the fixing frame 10 is hinged with a connecting support plate 11. The sides of the outer template 2 and the connecting support plate 11 are provided with positioning threaded holes 12, and the internal threads of the positioning threaded holes 12 are connected with positioning bolts 13. Through the cooperation of the fixing frame 10, the connecting support plate 11, the positioning threaded holes 12 and the positioning bolts 13, when the installation of this template is completed, the staff can pull out the connecting support plates 11 located on the left and right sides of the outer template 2 and close to the ground, so that the bottom end thereof is against the ground, thereby playing a supporting effect and reducing the probability of tipping. At the same time, the staff installs the positioning bolts 13 into the inside of the positioning threaded holes 12 of the outer template 2 and the connecting support plate 11, so as to enhance the stability of the outer template 2 and other outer templates 2.

[0029] Among them, the outer side of the inner template 1 and the inner side of the outer template 2 are fixedly connected with a reinforcement ring 14, and the top and bottom of the reinforcement ring 14 are fixedly connected with a reinforcement bar 15. By setting the reinforcement ring 14 and the reinforcement bar 15, the connection effect is strengthened. At the same time, deformation can be effectively avoided, thereby improving the service life.

[0030] The working principle of the above embodiment is:

[0031] After the steel mesh is tied, use an excavator to install the arc template 101 first. After the installation is completed, insert the trapezoidal template 3 into the gap to make the inner template 1 form a complete circle, and then install the first fixing bolt 5 to the inside of the first threaded hole 4, and then install the third fixing bolt 9 to the inside of the third threaded hole 8 of the arc template 101. The installation is divided into three times to complete the installation of the inner template 1. Among them, after the installation of the inner template 1 is completed, the second fixing bolt 7 is installed to the inside of the second threaded hole 6, and then the third fixing bolt 9 is installed to the inside of the third threaded hole 8 of the semicircular template 201. The installation is also divided into three times to complete the installation of the outer template 2. It should be noted that the installation method of the three inner templates 1 and the three outer templates 2 is a stacked installation, and the installation of the entire template is connected by bolts. The template connection is firm and no external reinforcement is required. At the same time, due to the large rigidity of the steel template and the extremely small connection gap, during the entire concrete pouring process, the template has no leakage and deformation, and the appearance quality of the poured concrete inspection well is smooth without obvious misalignment.

[0032] The electrical components mentioned in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role, and the existing public power connection technology is not described in detail in the text.
