Description

Technical Field

[0001] The present application relates to the technical field of P-type water seals, and in particular to a P-type water seal welding device. Background Art

[0002] P-type water seal, also known as P-type water-stop rubber (gate water seal), is mainly used in construction joints and deformation joints when concrete is cast in place. It is integrated with the concrete structure in foundation projects, underground facilities, tunnels and culverts, water supply aqueducts, retaining dams, etc. to ensure the service life of the project construction.

[0003] In traditional technology, when welding P-type water seal joints, the P-type water seal joints to be welded are usually placed on the gate. The center positions of the two joints are adjusted by manually observing the misalignment of the P-type water seal joints so that the two are concentric. Then the two joints are fixed to ensure the accurate welding of the two P-type water seal joints.

[0004] However, there is a large error in the method of manually observing and fixing the joints, which will cause slight misalignment and gaps in the joint positions. Utility Model Content

[0032] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings to facilitate understanding by technical personnel.

[0033] Example 1:

[0034] See also Figures 1 to 3 , a P-type water seal welding device, the P-type water seal welding device comprising:

[0035] An upper template 1 is provided with an elongated arc cavity 2, one side of which is provided with an upper elongated groove 3, and the elongated arc cavity 2 and the upper elongated groove 3 are integrally formed;

[0036] The lower template 4 is provided with a lower elongated groove 5, one side of which transitions to the upper end surface of the lower template 4 in an arc shape;

[0037] Among them, when the upper template 1 and the lower template 4 fit together and their four side walls are flush, the long arc cavity 2, the upper long strip groove 3 and the lower long strip groove 5 form a limiting space that matches the P-type water seal joint.

[0038] Specifically, the upper template 1 and the lower template 4 are both rectangular structures, and the length, width and height of the two are consistent. The long arc cavity 2 is opened at the lower part of the upper template 1, and the cross section of the long arc cavity 2 is an arc shape with an open lower end. The upper long strip groove 3 is located on the side of the lower end opening of the long arc cavity 2; the lower long strip groove 5 is opened at the upper part of the lower template 4, and one side of the lower long strip groove 5 is smoothly transitioned to the upper end surface of the lower template 4 through the arc, and the groove depth of the lower long strip groove 5 is consistent with that of the upper long strip groove 3;

[0039] When in use, first cut the end face of the P-type water seal joint to be welded flat, file, clean and glue it, then place the P-type water seal joint to be welded in the upper template 1 and the lower template 4, push the two ends of the P-type water seal joint and press it toward the center with force, then close the upper template 1 and the lower template 4, and make the four side walls of the two flush. At this time, the outer surface of the P-type water seal joint to be welded fits with the inner surface of the long arc cavity 2, the upper long strip groove 3 and the lower long strip groove 5, and the P-type water seal joint is confined in the limited space formed by the three. Then start welding. After the operation is completed, separate the upper template 1 and the lower template 4.

[0040] In this embodiment, the long arc cavity 2, the upper long strip groove 3 and the lower long strip groove 5 constitute a limited space that matches the P-type water seal joint. The welding operation is performed by restricting the P-type water seal joint to be welded within the limited space to avoid slight misalignment and gaps in the joint position caused by human errors, thereby ensuring the precise welding of the P-type water seal joint.

[0041] In addition, the P-type water seal welding device of the present application has a short manufacturing time, is light in weight, is easy to transport and disassemble, can be reused many times, greatly reduces the misalignment of the joints, and improves the welding efficiency of the P-type water seal joints.

[0042] Example 2:

[0043] See also Figure 1 Based on the first embodiment, optionally, a temperature sensor 6 is installed on the upper template 1 and the lower template 4 respectively.

[0044] Specifically, the temperature sensor 6 is electrically connected to the temperature control system. By setting the temperature sensor 6, the P-type water seal hot melting process is monitored in real time, and the temperature changes in the welding process are timely fed back to detect the welding effect. At the same time, the heating temperature can be adjusted in time according to the temperature changes to ensure that the P-type water seal joint is fully welded, thereby avoiding the phenomenon of unfused joints and poor sealing effect due to insufficient temperature during the hot melting process.

[0045] It should be noted that the temperature sensor 6 is a prior art and its structure is not described in detail here.

[0046] Optionally, a cooling water pipe 7 is installed on the upper template 1 and the lower template 4 respectively, and one end of the cooling water pipe 7 is connected to the coolant.

[0047] Specifically, the cooling water pipe 7 is electrically connected to the coolant system, and coolant is provided in time during the hot melt process according to the bonding process and temperature feedback to avoid the water seal hot melt joint temperature being too high. The coolant system provides coolant of different temperatures in real time to control the hot melt temperature.

[0048] Optionally, the cooling water pipe 7 is a galvanized steel pipe.

[0049] Specifically, galvanized steel pipes are durable and long-lasting. Hot-dip galvanized steel pipes feature a lustrous surface, a uniform zinc coating, no missing or dripping coating, strong adhesion, and excellent corrosion resistance. The zinc coating forms a metallurgical bond with the steel, becoming an integral part of the steel surface. This ensures a durable and cost-effective coating.

[0050] Optionally, the upper template 1 and the lower template 4 are cast from thick aluminum plates.

[0051] Specifically, aluminum plates have excellent corrosion resistance, can resist oxidation and corrosion, and increase service life; aluminum plates are light in weight, stable in structure, and easy to move; in addition, aluminum plates also have the advantage of low cost.

[0052] Example 3:

[0053] See also Figure 4 Based on the above embodiment, optionally, a handle 8 is provided on the upper end surface of the upper template 1.

[0054] Specifically, the lower end of the handle 8 is fixedly connected to the upper end surface of the upper template 1 or detachably connected by screws. By providing the handle 8, it is convenient to lift the upper template 1, thereby facilitating the fitting and separation of the upper template 1 and the lower template 4.

[0055] Optionally, a flexible rubber layer or a sponge layer is bonded to the surface of the handle 8 .

[0056] Specifically, a flexible rubber layer or a sponge layer is provided to increase the comfort of holding and increase the friction, so that the movement of the upper template 1 is more stable.

[0057] It should be noted that the structures and / or installation methods not detailed in this application are known to those skilled in the art in combination with common knowledge and / or existing technologies, and are not the focus of disclosure in this application and will not be further elaborated here.

[0058] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings are not related to the specific objects, and the dimensions of the objects can be changed arbitrarily.
