Description
Technical Field
[0001] The present application relates to the technical field of concrete waterproof construction, and in particular to a waterproof structure for a pool wall construction joint. Background Art
[0002] Concrete pool refers to a pool built with concrete materials and has a certain water storage capacity. Concrete pools have the advantages of strong structure, good durability, long service life and controllable construction cost. Concrete pools are widely used in various fields, such as industry, agriculture, urban construction, etc., for storing natural water, wastewater and liquid raw materials.
[0003] Generally speaking, the stronger the water storage capacity of a concrete pool, the more concrete raw materials are needed to build the concrete pool (hereinafter referred to as "concrete pool" for short). For pools that require more concrete raw materials, the concrete pouring operation needs to be divided into several times according to the actual functional area division, size and special structure of the pool. The joint between two adjacent concrete pouring operations is called the "construction joint" of concrete pouring.
[0004] In order to reduce the amount of water accumulated in the pool that is lost through the construction joints, it is usually necessary to bury long strips of water-stopping steel plates at the construction joints. Both sides of the water-stopping steel plates are usually provided with bent parts, called "flanges", to further improve the waterproof performance. During the concrete pouring process, with the continuous impact and extrusion of the concrete, the water-stopping steel plates will tilt to a certain extent, thus affecting the water-stopping effect of the water-stopping steel plates. Utility Model Content
[0005] In order to reduce the tilt angle of the water-stop steel plate during the concrete pouring process, the present application provides a pool wall construction joint waterproof structure.
[0006] The present application provides a pool wall construction joint waterproof structure, which adopts the following technical solution:
[0007] A waterproof structure for a pool wall construction joint comprises a waterstop steel plate and a support rod, wherein the waterstop steel plate is provided with a plurality of through holes, the plurality of through holes are distributed on both sides of the waterstop steel plate, the support rod is passed through the through holes, both ends of the support rod are provided with connecting devices, and the support rod is installed on the steel bars in the pool concrete through the connecting devices.
[0008] Through the above technical scheme, before the pouring of the pool concrete begins, the support rod is first inserted into the through hole on the waterstop steel plate, and then the support rod is installed on the steel bar of the pool concrete through the connecting device, so that the waterstop steel plate is located at the construction joint between the upper and lower layers of concrete pouring of the pool, that is, the lower half of the waterstop steel plate is located in the lower concrete pouring area, and the upper half of the waterstop steel plate is located in the upper concrete pouring area.
[0009] After the installation of the waterstop steel plate and support rods is completed, the concrete of the lower pool is poured. During the pouring of the lower concrete, the support rods and steel bars hinder the waterstop steel plate, thereby reducing the inclination angle of the waterstop steel plate during the concrete pouring process, thereby improving the waterproof effect of the waterstop steel plate.
[0010] In a preferred example, the utility model can be further configured as follows: a plurality of the through holes are opened on the flange of the water-stop steel plate.
[0011] Through the above technical solution, since the through holes are opened on the flange of the waterstop steel plate instead of opening the through holes on the main body in the middle of the waterstop steel plate, the influence of the opening of the through holes on the waterstop effect of the waterstop steel plate is reduced.
[0012] In a preferred example, the utility model can be further configured as follows: the connecting device includes half ring one and half ring two, the half ring one and the half ring two are rotatably arranged on the support rod, the half ring one and the half ring two can be mounted on the steel bars in the pool concrete, a connecting piece is arranged between one end of the half ring one away from the support rod and one end of the half ring two away from the support rod, and the half ring one and the half ring two are connected via the connecting piece.
[0013] Through the above technical solution, the operator installs half ring one and half ring two on the steel bars of the pool concrete, so that the steel bars are clamped between half ring one and half ring two, and then connects half ring one and half ring two through connecting parts, so that the support rods can be supported by the steel bars, thereby fixing the waterstop steel plate at the current height.
[0014] In a preferred example, the utility model can be further configured as follows: a limiting groove is provided in the second half ring, and the limiting groove is used to accommodate the ribs on the steel bar.
[0015] Through the above technical solution, if the steel bars in the pool concrete are ribbed steel bars, by fine-tuning the height of the waterstop steel plate, the ribs on the steel bars are placed in the limiting grooves of the half ring two, so that the ribs on the steel bars can be used to prevent the half ring one from moving downward, thereby reducing the possibility of the support rod and the waterstop steel plate sliding downward.
[0016] In a preferred example, the utility model can be further configured as follows: the connecting member includes a bolt and a nut, and the half ring 1 and the half ring 2 are connected by the bolt and the nut.
[0017] Through the above technical solution, after the operator installs half ring one and half ring two on the steel bars of the pool concrete, the operator inserts bolts into half ring one and half ring two and threads nuts onto the bolts. In this way, the possibility of half ring one and half ring two becoming loose is reduced due to the obstruction of the bolts.
[0018] In a preferred example, the utility model can be further configured as follows: the half ring 1 is provided with a plurality of adjustment holes 1 for the bolts to pass through, the half ring 2 is provided with a plurality of adjustment holes 2 for the bolts to pass through, and the half ring 1 is provided with an adjustment groove for accommodating the half ring 2.
[0019] Through the above technical scheme, when the diameter of the steel bars used in the pool concrete is smaller than the inner diameter of half ring one and half ring two, the operator rotates half ring two so that half ring two enters the adjustment groove of half ring one, thereby reducing the maximum spacing distance between half ring one and half ring two, so that the outer wall of the steel bars with a smaller radius can abut against the inner wall of half ring one and half ring two, so that the waterstop steel plate can be supported with the help of the steel bars, effectively expanding the scope of application of this structure.
[0020] In a preferred example, the utility model can be further configured as follows: a waterproof sleeve is inserted into the through hole, and the support rod is inserted into the waterproof sleeve.
[0021] Through the above technical scheme, the waterproof sleeve can be made of an expansion waterstop strip or a material with expansion waterstop properties. When water seeps into the construction joint, the waterstop sleeve will expand after encountering water to reduce the possibility of entering the other side of the waterstop steel plate through the through hole, thereby further improving the waterstop effect of the waterstop steel plate.
[0022] In a preferred example, the utility model can be further configured as follows: two support blocks are arranged on the waterproof sleeve, the two support blocks are respectively located on both sides of the waterproof sleeve, and the support blocks are abutted and matched with the water-stopping steel plate.
[0023] Through the above technical solution, since the support block and the waterstop steel plate are in abutment with each other, the possibility of the waterstop steel plate tilting is further reduced under the obstruction of the support block.
[0024] In summary, the utility model includes the following beneficial technical effects:
[0025] 1. The waterstop steel plate is installed on the steel bars in the pool concrete through the support rod, half ring one and half ring two. During the pouring of the lower concrete, the support rod and the steel bar hinder the waterstop steel plate, which reduces the tilt angle of the waterstop steel plate during the concrete pouring process, thereby improving the waterproof effect of the waterstop steel plate;
[0026] 2. By rotating the half ring 2 to adjust the maximum spacing distance between the half ring 1 and the half ring 2, the outer wall of the steel bar with a smaller radius can abut against the inner wall of the half ring 1 and the half ring 2, so that the water stop steel plate can be supported by the steel bar with a smaller radius, effectively expanding the scope of application of this mechanism;
[0027] 3. By filling the through hole of the waterstop steel plate with a waterstop sleeve, the possibility of entering the other side of the waterstop steel plate through the through hole is reduced, thereby further improving the waterstop effect of the waterstop steel plate.

[0034] The following is combined with Figure 1 -Attached Figure 4 This application is described in further detail.
[0035] The present application discloses a pool wall construction joint waterproof structure. Figure 1 What is shown in FIG. 1 is the state where the water stop steel plate 1 is buried in the next concrete.
[0036] See attached Figure 1As shown, a pool wall construction joint waterproof structure includes a water-stop steel plate 1 and a plurality of support rods 2. The water-stop steel plate 1 is vertically arranged, arranged along the length direction of the construction joint, and the two sides of the water-stop steel plate 1 are respectively in the two adjacent concrete pouring areas of the pool, and the flanges on both sides of the water-stop steel plate 1 are also respectively in the two adjacent concrete pouring areas of the pool. The support rods 2 are made of hard materials, and the plurality of support rods 2 are horizontally arranged and buried in the pool concrete.
[0037] See attached Figure 2 and attached Figure 3 As shown, a plurality of through holes 101 are opened on the waterstop steel plate 1 in the horizontal direction, the support rod 2 is passed through the through holes 101, the plurality of through holes 101 are evenly distributed on both sides of the waterstop steel plate 1, and the plurality of through holes 101 are opened on the flange of the waterstop steel plate 1 to reduce the influence of the opening of the through holes 101 on the waterstop effect of the waterstop steel plate 1.
[0038] See attached Figure 2 and attached Figure 4 As shown, both ends of the support rod 2 are provided with connecting devices 3, and the support rod 2 is installed on the longitudinal steel bars 4 in the pool concrete through the connecting devices 3. Since the structure of each connecting device 3 is basically the same, only the connecting device 3 at one end of the support rod 2 is described in detail below, and the connecting device 3 at the other end is not repeated.
[0039] See attached Figure 2 and attached Figure 4 As shown, the connecting device 3 includes a half ring 1 31 and a half ring 2 32. The half ring 1 31 and the half ring 2 32 can be installed in an embrace on the longitudinal steel bars 4 in the pool concrete. The thickness of the half ring 1 31 is greater than the thickness of the half ring 2 32, and the radius of the half ring 1 31 is consistent with the radius of the half ring 2 32.
[0040] See attached Figure 2 and attached Figure 4 As shown, one end of half ring 1 31 and one end of half ring 2 32 are both rotatably disposed on the end of support rod 2, and a connecting member 5 is disposed between the other end of half ring 1 31 and the other end of half ring 2 32, and the connecting member 5 includes a bolt 51 and a nut 52, and half ring 1 31 and half ring 2 32 are connected by the bolt 51 and the nut 52.
[0041] Before the pool concrete is poured, several support rods 2 are respectively inserted into the through holes 101 on both sides of the waterstop steel plate 1, and then the half ring 1 31 and the half ring 2 32 are installed on the longitudinal steel bars 4 of the pool concrete, so that the steel bars 4 are clamped between the half ring 1 31 and the half ring 2 32, and the half ring 1 31 and the half ring 2 32 are fixed by bolts 51 and nuts 52, so that the lower half of the waterstop steel plate 1 is in the lower concrete pouring area, and the upper half of the waterstop steel plate 1 is in the upper concrete pouring area.
[0042] In this way, during the pouring of the lower layer of concrete, the support rods 2 and the steel bars 4 hinder the waterstop steel plate 1, thereby reducing the inclination angle of the waterstop steel plate 1 during the concrete pouring process, thereby improving the waterproof effect of the waterstop steel plate 1, and then gradually pouring the upper layer of concrete.
[0043] See attached Figure 2 and attached Figure 4 As shown, a plurality of adjustment holes 311 for the bolts 51 to pass through are opened in the vertical direction on the half ring 1 31, and the plurality of adjustment holes 311 are evenly distributed along the circumference of the half ring 1 31; a plurality of adjustment holes 322 for the bolts 51 to pass through are opened in the vertical direction on the half ring 2 32, and the plurality of adjustment holes 322 are evenly distributed along the circumference of the half ring 2 32; an adjustment groove 312 for accommodating the half ring 2 32 is opened through the half ring 1 31.
[0044] If the diameter of the steel bar 4 is smaller than the inner diameter of the half ring 1 31, the half ring 2 32 is rotated so that the half ring 2 32 enters the adjustment groove 312 of the half ring 1 31 to reduce the maximum spacing distance between the half ring 1 31 and the half ring 2 32, so that the outer wall of the steel bar 4 with a smaller radius can abut against the inner walls of the half ring 1 31 and the half ring 2 32, so that the water stop steel plate 1 can be supported by the steel bar 4, effectively expanding the scope of application of the present structure.
[0045] See attached Figure 2 and attached Figure 4 As shown, a limiting groove 321 is provided in the semi-ring 2 32, and the limiting groove 321 is used to accommodate the ribs 41 on the steel bar 4, and the adjusting groove 312 can also accommodate the ribs 41 on the steel bar 4. When the operator places the ribs 41 on the steel bar 4 in the limiting groove 321 or the adjusting groove 312, the possibility of the support rod 2 and the water stop steel plate 1 sliding downward is reduced under the obstruction of the ribs 41 on the steel bar 4.
[0046] See attached Figure 2 and attached Figure 3 As shown, each through hole 101 is penetrated by a waterproof sleeve 6, and the waterproof sleeve 6 is made of expandable waterproof rubber. The support rod 2 is penetrated by the waterproof sleeve 6. When water seeps into the construction joint, the waterproof sleeve will expand after encountering water, so as to reduce the possibility of entering the other side of the waterproof steel plate 1 through the through hole 101.
[0047] See attached Figure 2 and attached Figure 3As shown, in addition, two support blocks 61 are provided on the waterproof sleeve 6. The support blocks 61 and the waterproof sleeve 6 are integrally formed. The two support blocks 61 are respectively located on both sides of the waterproof sleeve 6. The support blocks 61 and the water-stopping steel plate 1 are abutted and matched. Under the obstruction of the support blocks 61, the possibility of the water-stopping steel plate 1 tilting is further reduced.
[0048] The implementation principle of this embodiment is: the waterstop steel plate 1 in this structure is installed on the longitudinal steel bars 4 in the pool concrete through the support rod 2, half ring one 31 and half ring two 32. During the pouring of the lower layer of concrete in the pool, the support rod 2 and the steel bars 4 hinder the waterstop steel plate 1, which reduces the inclination angle of the waterstop steel plate 1 during the concrete pouring process, thereby improving the waterproof effect of the waterstop steel plate 1.
[0049] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application in sequence. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
