Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of industrial and civil construction engineering, and relates to an auxiliary tool for the construction of engineering waterproofing membranes, and in particular to an auxiliary tool for the construction of engineering waterproofing membranes which has good applicability, good practicality, is easy to operate and can improve the laying quality of the engineering waterproofing membranes. Background Art
[0002] The special construction specifications for engineering waterproofing require that the construction of waterproof membranes should ensure that there are no wrinkles, hollows, warped edges, etc. on the surface of the membranes after construction, and the joints between the membranes should also be tightly bonded. However, in actual construction, the membranes cover a large working area, and it is not easy to fully meet the above standards without the use of external objects. Therefore, during construction, membrane roller tools are often used to roll the working surface after the membranes are laid.
[0003] Although common roller pressing tools are sufficient for roller-assisted construction tasks on large-scale flat surfaces with gentle slopes, they still have the following disadvantages: (1) The effect of improving the bonding strength of the roll material is limited due to the influence of temperature. The hardness of the roll material bonding material will be affected by temperature. When the temperature is low, the hardness will be too high, which is not conducive to the roller bonding of the material. Common roller pressing tools mostly rely on the weight of the roller itself to apply pressure to the surface of the waterproof roll material, thereby improving the bonding strength of the roll material. Moreover, due to the simple structure, it is not conducive to the external pressure applied by the operator; (2) In actual projects, the complexity of the waterproofing working surface objectively exists. Common roller pressing tools are relatively bulky and it is difficult to fully perform the auxiliary construction of complex working surfaces while being easy to operate; (3) In actual projects, the waterproofing working surface is often not a single large-scale horizontal surface or a slope with a gentle slope, but includes many angles, large slopes, planes or arcs. It can be said that the working surface of the waterproofing roll material construction is relatively complex.
[0004] Therefore, it is of great practical significance to develop an auxiliary tool for the construction of engineering waterproof membranes that has good applicability, good practicality, easy operation and can improve the laying quality of engineering waterproof membranes. Utility Model Content

[0011] The utility model is an auxiliary tool for the construction of engineering waterproofing membranes, with a reasonable structural design and multiple operation modes. In addition to hand-held operation by applying roller pressure by force of the hands, the operator can also use the body (abdomen) to press against the U-shaped pad to apply roller pressure by relying on its own weight, which is easy to operate; the composite roller adopts two rollers of different diameters, the front roller has a small diameter and can be used for rolling at the inner corner, and the rear roller has a large diameter and can be used for rolling at a large area of the working surface. When the two are used at the same time, the roller pressure problem at the outer corner can be solved, the construction quality is good, and the application prospect is good.
[0012] As the preferred technical solution:
[0013] In the auxiliary tool for waterproofing membrane construction, the Y-shaped frame further comprises a buffer cushion, which is mounted on the U-shaped pad by bolts. The buffer cushion is made of flexible rubber to reduce the sharp pressure on the abdomen of the operator.
[0014] As described above, an auxiliary tool for the construction of engineering waterproofing membranes, the T-shaped rod comprises a U-shaped clip and a T-shaped slot rod;
[0015] The U-shaped clip is mounted on the T-shaped structure side of the T-shaped slot rod through bolts, and a limit bolt is installed at the other end of the T-shaped slot rod.
[0016] As described above, an auxiliary tool for the construction of engineering waterproofing membranes is provided on the insertion rod with a row of fixed limit holes that match the limit bolts and are arranged in sequence along the length direction of the insertion rod. The overall structure is a telescopic structure, which can automatically adjust the optimal working length and the angle between the rod and the working surface according to the height of the operator, which is beneficial for the operator to apply additional pressure to roll the membrane.
[0017] As described above, in the auxiliary tool for the construction of engineering waterproofing membranes, the limit bolt is cylindrical in shape as a whole, and has latch fixing holes at both ends thereof. The limit can be achieved by inserting the latch into the latch fixing hole.

[0019] The arc-shaped steel sheet is provided with an insertion hole matching the fixing hole of the composite roller, and the latch passes through the fixing hole of the composite roller and the insertion hole in sequence to achieve the fixation of the U-shaped clip and the composite roller.
[0020] In the auxiliary tool for the construction of engineering waterproofing membranes as described above, the latch, the front roller and the rear roller are parallel to each other and their axes of symmetry are not located on the same plane.

[0022] The above technical solution is only a feasible technical solution of the present invention. The protection scope of the present invention is not limited to this. Those skilled in the art can reasonably adjust the specific design according to actual needs.
[0023] The auxiliary tool for the construction of engineering waterproofing membranes of the utility model can significantly improve the applicability and convenience of traditional pressure roller auxiliary tools and improve the quality of engineering waterproofing. As an auxiliary tool, it does not change the waterproof principle of the waterproof membrane itself, but only optimizes the common pressure roller tool. This optimization can not only directly achieve the above-mentioned purpose, but also indirectly improve the working efficiency and reduce the difficulty of the operation.
[0024] The above utility model has the following advantages or beneficial effects:
[0025] (1) The utility model is an auxiliary tool for the construction of engineering waterproofing membranes. It adopts a telescopic structure and can adjust the optimal working length and the angle between the rod and the working surface according to the height of the operator, which is conducive to the operator to apply additional pressure to roll the membrane. The abdominal-supporting component design allows the operator to apply rolling pressure by relying on his own weight, which reduces the intensity of construction work and improves the work efficiency. The buffer cushion adopts flexible rubber, which strives to achieve the purpose of reducing the sharp pressure on the abdomen of the operator;
[0026] (2) The utility model is an auxiliary tool for the construction of engineering waterproofing membranes, which is helpful to reduce the influence of ambient temperature on the bonding performance of the membranes. The utility model has two operating modes: hand-held type and belly-leaning type. The hand-held type is conducive to use under conditions of large slopes and narrow working surfaces, while the belly-leaning type is conducive to use under conditions of gentle slopes and large working areas. In low-temperature weather, the adhesive material of the waterproofing membrane hardens, so the rolling pressure should be increased. When operating, the operator adjusts the inclination of his own standing posture and applies his own weight to the rod or buffer cushion, which can add additional pressure to perform the rolling operation;
[0027] (3) The auxiliary tool for the construction of engineering waterproofing membranes of the utility model has flexible and changeable shapes, which is conducive to auxiliary construction. The composite roller adopts two rollers of different diameters. The front roller has a small diameter and can be used for rolling at the inner corner. The rear roller has a large diameter and can be used for rolling on a large working surface. When the two rollers are used at the same time, the rolling problem at the outer corner can be solved.
[0028] In summary, in addition to the convenience in operation and the humanized design, all the combinations of the operation mode and the tool form make the utility model more practical and have a wider range of uses. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.
[0037] Example 1
[0038] An auxiliary tool for the construction of engineering waterproof membranes, such as Figure 1 As shown, it includes a T-shaped rod 1, a Y-shaped frame 2 and a composite roller 3;
[0039] Composite roller 3 Figure 4 As shown, it includes a front roller 301 and a rear roller 302 with different outer diameters (the outer diameter of the front roller 301 is smaller than that of the rear roller 302). The front roller 301 and the rear roller 302 are parallel to each other, and arc-shaped steel sheets 303 are provided on both sides of the front roller 301 and the rear roller 302 for fixing the two rollers. The arc-shaped steel sheets 303 have insertion holes that match the fixing holes of the composite roller. The latch I, the front roller 301, and the rear roller 302 are parallel to each other, and the symmetry axes of the three rollers are not located in the same plane.
[0040] Y-shaped frame 2 Figure 3 As shown, it includes a Y-shaped slot rod 201 and a buffer cushion 202. The Y-shaped slot rod 201 includes an insertion rod and a U-shaped cushion. The middle part of the U-shaped cushion is fixed to the insertion rod, and the whole is Y-shaped. The insertion rod is provided with a row of fixed limit holes 2011 that match the limit bolts 103 and are arranged in sequence along the length of the insertion rod. The buffer cushion 202 is mounted on the U-shaped cushion by bolts.
[0041] T-bar 1 Figure 2 As shown, it includes a U-shaped clamp 101 and a T-slot rod 102. The U-shaped clamp 101 is installed on the T-shaped structure side of the T-slot rod 102 by bolts. The composite roller 3 is installed on the U-shaped clamp 101 and the arc-shaped steel sheet 303 is fixed to the U-shaped clamp 101 (a pair of composite roller fixing holes 1011 that match each other are opened on both sides of the U-shaped clamp 101. The pin I passes through the composite roller fixing holes 1011 and the plug hole in sequence to achieve the fixation of the U-shaped clamp 101 and the composite roller 3, and the composite roller 3 can rotate around the pin I). The other end of the T-slot rod 102 is provided with a limit bolt 103 and is plugged and fixed with the plug rod (it is a nested connection. The two are nested with each other through rods with different widths and heights, and the relative movement of the two is restricted by the limit bolt 103). The limit bolt 103 is as shown Figure 5 As shown, the whole is cylindrical, and a pin fixing hole is provided at both ends. The pin II is inserted into the pin fixing hole to fix the limit bolt 4.
[0042] The U-shaped clamp and T-slot rod are connected by interlocking and bolting. The vertical surface of the U-shaped clamp fits snugly into the U-shaped groove in the transverse portion of the T-slot rod, restricting vertical relative movement. Meanwhile, bolts extend longitudinally through reserved stop holes in the clamp, limiting relative movement in all directions. To prevent the two ribs in the transverse groove of the T-slot rod from directly contacting the composite roller during operation, the length of the two ribs should be consistent with the thickness of the U-shaped clamp. The composite roller and T-slot rod are connected by a latch I or bolts, allowing the composite roller to rotate within a range of 240° around the latch I. Based on the connection method and actual operating conditions, two operating modes of the auxiliary tool are derived: one, designated as Mode I, in which the composite roller is in full contact with the work surface; the other, designated as Mode II, in which the rear roller is in sole contact with the work surface. These two modes can be switched by rotating the composite roller. In Mode I, the leading roller rests against the upper surface of the U-shaped clamp, while the rear roller is in sole contact with the work surface. The need for a front roller in the auxiliary tool is due to the fact that when laying waterproofing membrane in internal corners, the restricted angle, thickness, and hardness of the membrane make it difficult for the membrane to adhere firmly to the corresponding work surface, thus reducing the overall waterproofing quality. The relatively small diameter of the front roller makes it easier to conform to the corner. At the same time, due to its smaller contact surface with the membrane, it is easier to generate greater pressure to ensure a firm adhesion. To facilitate operation and to apply greater rolling pressure to the work surface, the rear roller can be set to a diameter of approximately 12 cm or other length that is more conducive to construction, and a length of approximately 50 cm or other length that is more conducive to construction. The diameter ratio of the front roller to the rear roller should be between 0.5 and 1, and the length should be the same. Of course, it is also possible to create stop holes on the T-slot rod that match the fixed stop holes on the Y-slot rod, with the two holes having the same hole spacing and diameter.
[0043] The above-mentioned auxiliary tools have two construction operation modes, namely hand-held type and belly-leaning type. Among them, the hand-held operation mode is: the operator holds the intersection of the horizontal and longitudinal parts of the T-slot rod with one hand, and holds the appropriate position of the rod with the other hand, and then rolls the roller back and forth to contact the target working surface. The belly-leaning operation mode is: first adjust the length, pull out the limit bolt, and then extend and retract the adjustment tool to the length suitable for the operation, and then insert the limit bolt to complete the adjustment; during operation, the operator presses his abdomen against the surface of the buffer cushion and the composite roller contacts the ground. At this time, the contact point between the roller and the working surface, the operator's belly-leaning point, and the operator's standing point are connected to form a triangle, and then the operator holds the longitudinal part of the Y-slot rod with both hands, while leaning forward and pushing the auxiliary tool to move on the target working surface.
