Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and in particular relates to a device for preventing grout leakage at template joints. Background Technology

[0002] In building structure construction, reinforced concrete is generally used for pouring. Before pouring, the reinforcing bars are tied, then the formwork is constructed and reinforced, and finally the concrete is poured. Currently, wooden formwork, aluminum formwork, and steel formwork are commonly used for formwork construction. Due to the high cost of aluminum formwork and its suitability only for mass production, and the heavy weight of steel formwork, wooden formwork is one of the most commonly used construction methods on the market. However, wooden formwork also has some problems in formwork construction.

[0003] First, wooden molds are easily damaged. After multiple uses, they are prone to minor chipping and breakage, resulting in excessively large gaps in the joints after splicing. This can easily lead to grout leakage during later concrete pouring. Second, if the wooden molds are not securely fixed after splicing, the joints can deform under the pressure of concrete, also causing excessively large gaps and grout leakage during pouring. Grout leakage can easily contaminate other finished products, leading to difficulties in later cleaning and affecting the appearance. To avoid grout leakage, wooden molds with minor chipping and breakage are usually discarded, resulting in material waste. In addition, the splicing of wooden molds needs to be reinforced and fixed, which requires too much fixing material and construction time. Summary of the Invention

[0004] The main objective of this invention is to provide a grout leakage prevention device for template joints, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A template joint anti-leakage treatment device includes a box body, a flexible transition pipe fixedly connected to the box body, a control handle fixedly connected to the front end of the flexible transition pipe, a hot melt pipe fixedly connected to the front end of the control handle, and a nozzle fixedly connected to the front end of the hot melt pipe.

[0007] The nozzle includes a hot melt nozzle and an air nozzle fixedly connected at the top and bottom. The hot melt nozzle has several rows of hot melt nozzle holes, which are arranged in an alternating manner with the left and right sides inclined. The air nozzle has air nozzles, which are arranged with the air nozzles inclined toward the hot melt nozzle.

[0008] The box is equipped with a hot melt material roll and an air pump;

[0009] The flexible transition tube is equipped with a hot melt material conduit, the control handle is equipped with a feeding wheel and a heating pipe and a pressurizing pipe connected to each other, the hot melt piping is equipped with a hot melt spray pipe, one end of the hot melt spray pipe is connected to the pressurizing pipe and the other end is connected to the hot melt spray head, and the hot melt material strip of the hot melt material roll is fed into the heating pipe by the feeding wheel after passing through the hot melt material conduit;

[0010] The air outlet of the air pump is connected to one end of the air duct, and the other end of the air duct is connected to the air nozzle.

[0011] Preferably, the control handle is further provided with a feeding motor and a pressurizing motor, the feeding motor being connected to the feeding wheel and the pressurizing motor being connected to the pressurizing pipe.

[0012] Preferably, the housing is further provided with a main board, and the control handle is provided with a control switch and an indicator light. The main board is electrically connected to the feeding motor, the pressurizing motor, the control switch, the indicator light, and the air pump.

[0013] Preferably, the enclosure also contains a battery, and the enclosure has a charging port, which is electrically connected to the battery via a motherboard.

[0014] Preferably, the housing has a shoulder strap.

[0015] Preferably, the outer surface of the hot melt spray pipe is covered with a heat insulation layer.

[0016] Preferably, the air conduit passes sequentially through the hot melt material conduit and the control handle, and is then fixedly connected to the hot melt piping in parallel.

[0017] Preferably, the box body has a lid.

[0018] Preferably, the hot melt nozzle is provided with a first connecting buckle, and the air nozzle is provided with a second connecting buckle.

[0019] This invention provides a grout leakage prevention device for template joints, which has the following beneficial effects;

[0020] An air nozzle directs fine filaments sprayed from a hot-melt nozzle to adhere and cover the joints of the wooden formwork, forming a mesh of a certain width. This mesh effectively intercepts grout during concrete pouring, preventing leakage due to excessive gaps caused by minor edge damage or tearing of the wooden formwork. Thus, even slightly damaged or torn wooden formwork can still be used normally. Furthermore, because the mesh has a certain degree of elasticity and toughness, even if the joints deform under concrete pressure, resulting in excessive gaps, grout leakage will not occur, reducing the requirements for formwork fixation.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] Examples, such as Figure 1-9 As shown, a template joint anti-leakage treatment device includes a box body 1, a flexible transition pipe 2 is fixedly connected to the box body 1, a control handle 3 is fixedly connected to the front end of the flexible transition pipe 2, a hot melt pipe 4 is fixedly connected to the front end of the control handle 3, and a nozzle 5 is fixedly connected to the front end of the hot melt pipe 4.

[0041] The nozzle 5 includes a hot melt nozzle 51 and an air nozzle 52 fixedly connected vertically. The hot melt nozzle 51 has several rows of hot melt nozzle holes 511, which are arranged in a staggered manner with left and right inclinations. The air nozzle 52 has air nozzles 521, which are arranged at an angle toward the hot melt nozzle 51.

[0042] In this embodiment, as Figure 7-9As shown, several rows of hot melt spray holes 511 are arranged in an alternating pattern with the left and right sides tilted. The first row of hot melt spray holes 511 is arranged with the left tilted side, the second row of hot melt spray holes 511 is arranged with the right tilted side, and the third row of hot melt spray holes 511 is arranged with the left tilted side. Two air nozzles are provided at the front end of the air nozzle 52. The air nozzle 52 has a Y-shaped structure inside and a certain degree of tilt. The airflow blown out is inclined to the hot melt spray head 51.

[0043] The housing 1 is equipped with a hot melt material roll 11 and an air pump 12.

[0044] The flexible transition tube 2 is equipped with a hot melt material conduit 21. The control handle 3 is equipped with a feeding wheel 31 and a heating tube 32 and a pressurizing tube 33 connected to each other. The heating tube 32 can be heated by conventional heating methods, such as relying on its own resistance to generate heat. The hot melt piping 4 is equipped with a hot melt spray pipe 41. One end of the hot melt spray pipe 41 is connected to the pressurizing tube 33, and the other end is connected to the hot melt spray head 51. The hot melt material strip of the hot melt material roll 11 passes through the hot melt material conduit 21 and is fed into the heating tube 32 by the feeding wheel 31.

[0045] The air outlet of the air pump 12 is connected to one end of the air duct 22, and the other end of the air duct 22 is connected to the air nozzle 521.

[0046] The working principle of this invention is as follows:

[0047] During operation, the hot melt nozzle 51 and air nozzle 52 are placed at the joint of the wooden mold. The hot melt strip of the hot melt material roll 11 passes through the hot melt material conduit 21 and is then fed into the heating pipe 32 by the feeding wheel 31 to melt. The melted hot melt material is pressurized through the pressurizing pipe 33 and then passes through the hot melt spray pipe 41. Finally, it is sprayed out as fine filaments through several rows of hot melt spray holes 511 on the hot melt nozzle 51. While the above process is running, the air pump 12 provides air. The air passes through the air conduit 22 and finally blows the fine filaments through the air spray holes 521 on the air nozzle 52, which then adhere to and cover the joint of the wooden mold, forming a mesh cloth of a certain width at the joint of the wooden mold. The mesh cloth can play a good interception role during concrete pouring, preventing the wooden mold from leaking grout during concrete pouring due to excessive gaps in the joint caused by slight edge damage or breakage. Thus, wooden molds with slight edge damage or breakage can still be used normally.

[0048] In addition, because the mesh fabric has a certain degree of elasticity and toughness, even if the joints of the wooden formwork deform under the pressure of concrete, resulting in excessive gaps between the joints, grout leakage will not occur, which can reduce the requirements for fixing the wooden formwork.

[0049] The arrangement of several rows of hot melt spray holes 511 at an angle and in an alternating manner makes it easier for the fine filaments to be sprayed out at an angle, which is more conducive to the adhesion of the two ends of the formed mesh cloth to the wooden mold. The present invention is even more effective when applied to wooden molds that have been used multiple times. After multiple uses, the wooden mold will form rough particles on its surface, which is more conducive to the adhesion of the mesh cloth.

[0050] In one specific embodiment, the control handle 3 is also equipped with a feeding motor 34 and a pressurizing motor 35. The feeding motor 34 is connected to the feeding wheel 31, which has a double gear structure. The feeding motor 34 drives the feeding wheel 31 to rotate and feed the hot melt material strip to the heating tube 32. The pressurizing motor 35 is connected to the pressurizing tube 33 and pressurizes the hot melt material in the pressurizing tube 33.

[0051] The housing 1 is also equipped with a main board 13. The control handle 3 is equipped with a control switch 36 and an indicator light 37. The main board 13 is electrically connected to the feeding motor 34, the pressurizing motor 35, the control switch 36, the indicator light 37, and the air pump 12. Pressing the control switch 36 can control the operation of each moving part of the device through the main board 13 to achieve automated control. The operating status of the device can be displayed through the indicator light 37.

[0052] The enclosure 1 is also equipped with a storage battery 15, and the enclosure 1 is equipped with a charging port 16, which is electrically connected to the storage battery 15 through the motherboard 13.

[0053] In one specific embodiment, the box 1 has shoulder straps 6, which facilitates construction workers to carry and walk on it. Common methods to prevent grout leakage from wooden molds are all mechanical structures, while this device is a mobile device that prevents grout leakage from the joints of wooden molds by spraying hot melt material. It is convenient to construct and simple to operate. The hot melt material can be selected from materials such as PVC.

[0054] In one specific embodiment, the outer surface of the hot melt spray pipe 41 is covered with a heat insulation layer 42 to prevent the hot melt material from solidifying due to heat loss when passing through the hot melt spray pipe 41.

[0055] In one specific embodiment, the air duct 22 passes sequentially through the hot melt material duct 21 and the control handle 3, and is then fixedly connected to the hot melt piping 4 in parallel to reduce the volume.

[0056] In one specific embodiment, the box body 1 has a box cover 17.

[0057] In one specific embodiment, the hot melt nozzle 51 is provided with a first connecting buckle 512 for connecting with the hot melt nozzle 41, and the air nozzle 52 is provided with a second connecting buckle 522 for connecting with the air duct 22.

[0058] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
