Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a wall positioning tool for a water supply internal thread elbow. Background Art

[0002] With the development of the construction industry, society's demands for construction are becoming increasingly stringent, especially in the installation and renovation of indoor water supply piping. Female water supply elbows are commonly used piping fittings, primarily categorized by angles of 45° and 90°. Other unconventional angles, such as 60°, are also available depending on project requirements. Female water supply elbows are widely used in a variety of fields, including construction, water supply and drainage, HVAC, and industrial piping.

[0003] During piping construction, imprecise positioning of the internal elbows at the hot and cold water pipe joints can lead to loose joints, which in turn can lead to quality risks such as internal leakage and loose decorative covers. While conjoined internal elbows are currently available on the market, they only control the spacing of the internal elbows, not the thickness of the elbows protruding from the wall. To address the spacing and thickness of the internal elbows protruding from the wall, the positioning and calibration of the internal elbows protruding from the wall are typically performed manually or visually.

[0004] Although the above-mentioned traditional construction method can perform positioning, measurement and correction, it still has the following shortcomings during actual use: low construction efficiency and low positioning accuracy, which affects the appearance of the later decoration and renovation stage; and the existing construction process describes that the threaded elbows at the water supply points are consistent with the wall, but there is no specific positioning method, which makes it difficult to control the consistent distance of the water supply points out of the wall. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art of low positioning accuracy and low construction efficiency of water supply internal thread elbows, and to provide a water supply internal thread elbow wall positioning tool, which has a reasonable design, simple structure, easy operation, and high positioning accuracy. It can not only improve construction efficiency, but also ensure the appearance of the later decoration stage. It is highly practical and suitable for promotion.

[0006] The utility model is realized through the following technical scheme: a wall positioning tool for a water supply internal thread elbow, comprising a horizontal level, on which an elbow positioning hole corresponding to the water supply internal thread elbow is opened, and two elbow positioning holes are provided and symmetrically distributed on the left and right; a tubular level is provided on the top side of the horizontal level, and a vertical level is fixedly connected to the bottom side of the horizontal level, and the horizontal level and the vertical level form a T-shaped structure; the two ends of the horizontal level and the bottom end of the vertical level are respectively screwed with through-adjusting positioning bolts, and the screw end face of the adjusting positioning bolt faces the wall.

[0007] A further improvement of the present invention is that an elevation control device is provided on the horizontal level, the elevation control device includes an infrared signal transmitter and an infrared signal receiver with signal connections, the infrared signal receiver is fixed to the top side of one end of the horizontal level, and the infrared signal transmitter is arranged at the floor building.

[0008] A further improvement of the present invention is that the bolt rod of the adjusting positioning bolt is connected with an adjusting gasket capable of closely contacting the wall surface.

[0009] A further improvement of the present invention is that a handheld handle is provided on the vertical level, and a tubular level is provided on one side of the vertical level.

[0010] A further improvement of the present invention is that the axis of the elbow positioning hole is located on the axis of the horizontal level, and the two elbow positioning holes are symmetrically distributed about the center of the horizontal level.

[0011] A further improvement of the present invention is that both the horizontal level and the vertical level are made of aluminum alloy, and both the horizontal level and the vertical level are 400 mm long.

[0012] A further improvement of the present invention is that the outer diameter of the elbow positioning hole is 42 mm, and the axial center distance between the two elbow positioning holes is 150 mm.

[0013] A further improvement of the present invention is that the horizontal level is provided with an adjusting positioning bolt at a distance of 70 mm from both ends thereof, and the vertical level is provided with an adjusting positioning bolt at a distance of 70 mm from the bottom end thereof.

[0014] A further improvement of the present invention is that two horizontal levels are provided, and the two horizontal levels are connected to each other via a connecting buckle.

[0015] From the above technical solutions, it can be seen that the beneficial effects of the utility model are as follows: the positioning tool has a simple structure and is easy to operate, which improves the accuracy of positioning the internal thread elbow of the water supply, thereby making the installation of the joints and decorative covers in the later decoration construction more rigorous, greatly reducing rework, saving construction costs, increasing construction speed, and facilitating standardized operations. At the same time, the positioning tool can be reused and can be used in multiple batches and multiple projects; and the positioning tool can be prefabricated in multiple pieces, and multiple positioning tools can be connected together through connecting buckles, so that they can be used in the construction of internal thread elbows of water supply at different spacings, with a wide range of applications.

[0023] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0024] Example 1, now refer to the attached Figure 1-3 The following is a description of the utility model: A wall positioning tool for a female elbow in a water supply system includes a horizontal level 1 and a vertical level 2. Both are made of aluminum alloy and are 400 mm long. It should be noted that the specific lengths of the horizontal level 1 and the vertical level 2 can be determined based on actual construction requirements.

[0025] The horizontal level 1 is provided with two elbow positioning holes 101 corresponding to the water supply internal thread elbow 8. The axis of the elbow positioning hole 101 is located on the axis of the horizontal level 1, and the two elbow positioning holes 101 are symmetrically distributed left and right about the center of the horizontal level 1. The outer diameter of the elbow positioning hole 101 is 42mm, and the axis spacing between the two elbow positioning holes 101 is 150mm. A tubular level 3 is provided at the top center of the horizontal level 1, and a vertical level 2 is fixedly connected to the bottom center of the horizontal level 1, and the horizontal level 1 and the vertical level 2 form a T-shaped structure.

[0026] Adjustment bolts 4 are threaded through each end of the horizontal level 1 and the bottom end of the vertical level 2. The ends of the screws of the adjustment bolts 4 face the wall 9, and the bolts are connected to adjustment washers 5 that can fit snugly against the wall 9. The three adjustment bolts 4 are located 70 mm from each end of the horizontal level 1 and 70 mm from the bottom end of the vertical level 2.

[0027] Specifically, the horizontal level 1 is provided with an elevation control device, comprising a signal-connected infrared signal transmitter and infrared signal receiver 6. Infrared signal receiver 6 is fixed to the top side of one end of the horizontal level 1, while the infrared signal transmitter is located on the floor. In combination with existing infrared control devices, the infrared signal transmitter is fixed 1.0m above each floor during construction. The elevation control device is used to control the elevation of the elbow positioning hole 101.

[0028] Specifically, a handheld handle 7 is provided at the center of the vertical level 2 , and a tubular level 3 is provided at the center of one side of the vertical level 2 .

[0029] The operating principle of this utility model:

[0030] First, before starting the construction of the water supply internal thread elbow 8, the staff first fixes the infrared signal transmitter at the 1.0m line of the floor building, and sets the infrared signal transmitter according to the actual elevation on site. The infrared signal transmitter cooperates with the infrared signal receiver 6 to control the elevation of the water supply internal thread elbow 8.

[0031] Secondly, the staff holds the handle 7 and places the positioning tool on the water supply internal thread elbow 8 to be installed. The two water supply internal thread elbows 8 are first virtually connected to the water pipe. The two elbow positioning holes 101 are respectively mounted on the two water supply internal thread elbows 8, and the elevation of the water supply internal thread elbow 8 is adjusted through the infrared signal receiver 6.

[0032] Again, after the elevation is adjusted correctly, the staff adjusts the distance of the positioning tool from the wall by rotating the adjustment bolt 4 according to the actual thickness of the on-site plastering; after the adjustment is in place, the adjacent water supply internal thread elbows 8 are adjusted through the tubular level 3 so that they can be on the same horizontal line. After the adjustment is completed, the water supply internal thread elbows 8 are fixed and connected to the water pipe.

[0033] Finally, after the water supply internal thread elbow 8 is fixed and connected, the staff holds the handle 7 to remove the positioning tool, and then can proceed to the construction of the water supply internal thread elbow 8 at the next part or other floors.

[0034] Example 2, now refer to the attached Figure 4 and 5 , explained as follows: Based on the first embodiment, two horizontal levels 1 are provided, that is, two positioning tools are provided, and the two horizontal levels 1 are connected to each other via a connecting buckle 10. The two positioning tools are connected together using the connecting buckle 10 to control water supply internal thread elbows of different spacings, thereby expanding the application range of the positioning tool. It should be noted that multiple positioning tools can be prefabricated, and multiple positioning tools can be connected to each other via the connecting buckle 10.
