Description

Technical Field

[0001] The utility model relates to the technical field of slope finding engineering for building construction, and specifically, to an auxiliary tool applied to parallel slope finding of precast caissons. Background Art

[0002] At present, precast toilet caissons in prefabricated components are a common prefabricated component structure form. The existing caisson construction method means that during the construction of the main body, the toilet structural layer is partially or wholly sunken by a certain height from the corresponding floor surface, so that the horizontal drainage pipes in the toilet can be buried therein, and then backfilled with lightweight materials. Only one hole needs to be provided on the structural surface for the drainage riser to pass through and be used.

[0003] In recent years, related incidents of toilet leakage have occurred frequently, seriously affecting the living experience of residents. At present, most of the post-treatment of precast caissons on the market is backfilling with waste residue, pouring mortar for leveling and slope finding after backfilling, and then constructing waterproof layers, cement mortar waterproof protection layers, and tile laying surfaces. This method has many processes, increases the load on the floor slab, is prone to cause overweight of the floor slab, and at the same time, the construction cost is also relatively high.

[0004] In view of this, the applicant has explored a method for quickly fabricating an integral integrated precast toilet caisson by using floor paving, modular supports, and modular equipment pipelines, which can effectively control the quality of components, increase the reliability of the self-waterproofing of the structure, effectively reduce the leakage risk, and to a certain extent, can also save waterproof materials, reduce the backfill area by more than 90%, and facilitate the maintenance of pipelines in the later stage.

[0005] However, the applicant has found in practice that although the bottom surface of the main body of the precast caisson can achieve slope finding in the precast stage by using existing molds (such as Chinese Patent Application for Invention CN202211452600.2), in order to drain the accumulated water on the floor paving, it is still necessary to separately perform slope finding treatment on the floor paving. Therefore, during the construction process, it is necessary to frequently calibrate the heights of each modular support, which is cumbersome, time-consuming, and laborious. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an auxiliary tool for parallel slope finding of precast caissons and a slope finding structure for floor paving. Taking the slope of the bottom surface of the main body of the precast caisson as a reference, parallel slope finding of the floor paving is realized through a parallelogram structure, the heights of each modular support can be quickly calibrated, the operation is simple, time-saving, and labor-saving, thereby solving the technical problems described in the background art.

[0007] To achieve the above purpose, the specific technical solutions adopted by the utility model are as follows:

[0008] An auxiliary tool for parallel slope finding of precast caissons, the key lies in: including a lower ruler corresponding to the slope of the bottom surface of the caisson main body box, and an upper ruler corresponding to the inclined surface of the modular support cushion block. The upper ruler and the lower ruler are constrained by two left and right connecting rods into a parallelogram structure with variable area.

[0009] Furthermore, the length of the connecting rod is adjustable, and any one of the connecting rods serves as a elevation reference ruler.

[0010] Furthermore, the elevation reference ruler includes a rod sleeve and a telescopic rod sleeved in the rod sleeve. The rod sleeve is hinged to the lower ruler, and the telescopic rod is hinged to the upper ruler.

[0011] Furthermore, a strip window is opened along the length direction on the rod sleeve. A first scale is arranged along the length direction on one side of the strip window, and a first scale mark is arranged on the telescopic rod corresponding to the first scale.

[0012] Furthermore, an angle measuring structure is arranged at any vertex of the parallelogram structure.

[0013] Furthermore, the angle measuring structure is arranged between the lower ruler and the elevation reference ruler.

[0014] Furthermore, the angle measuring structure includes a second scale arranged around the hinge point of the elevation reference ruler and the lower ruler, and a second scale mark arranged at the center of the second scale and rotating along with the elevation reference ruler.

[0015] Based on the above structure, the present invention also discloses a ground paving slope finding structure, including a slope with an inclination of θ arranged at the bottom of the precast caisson main body box and modular supports. The modular supports include a base embedded in the bottom of the caisson main body box, a liftable main body arranged on the base, a cushion block arranged on the liftable main body, and an inclined surface with an inclination of θ arranged on the cushion block. The key lies in: further including the auxiliary tool according to any one of claims 1-7. The lower ruler of the auxiliary tool realizes reference plane comparison by abutting against the slope along the length direction. The upper ruler of the auxiliary tool is compared with the ground paving elevation line. When the modular support is calibrated, the upper ruler of the auxiliary tool completely abuts against the inclined surface of the modular support.

[0016] Compared with the prior art, the remarkable effect of the present utility model is:

[0017] (1) With the auxiliary tool of the present utility model, parallel slope finding for ground paving can be achieved quickly and accurately, ensuring the parallelism and flatness of ground paving. In practical applications, the operator only needs to place the lower ruler of the auxiliary tool against the slope on the bottom of the caisson main body along the length direction, and then adjust the length or angle of the connecting rod to align the upper ruler with the ground paving elevation line. At this time, the height of the modular support can be calibrated according to the indication of the auxiliary tool to ensure that the heights of all modular supports are consistent;

[0018] (2) Since the auxiliary tool adopts a parallelogram structure, the relative position between the upper ruler and the lower ruler can be conveniently adjusted to adapt to different slopes and ground paving requirements. At the same time, by setting an angle measuring structure and scale markings, the operator can more intuitively understand the angle and length changes of the connecting rod, thereby more precisely controlling the height of the modular support;

[0019] (3) The auxiliary tool of the present utility model has the advantages of simple structure, easy operation, time-saving, labor-saving, and high precision. With the cooperation of the slope on the bottom of the caisson main body and the liftable main body of the modular support, the construction efficiency and quality of parallel slope finding for precast caissons can be significantly improved.

[0030] Figure 1 The first embodiment of the present utility model is presented: An auxiliary tool for parallel slope finding of precast caissons includes a lower reference ruler 2 corresponding to the slope surface 6 of the bottom of the caisson main body box, and an upper reference ruler 1 corresponding to the inclined surface 704 of the cushion block 703 of the modular support 7. The upper reference ruler 1 and the lower reference ruler 2 are constrained by two left and right connecting rods 3 into a parallelogram structure with variable area.

[0031] Refer to Figure 2 , the method for calibrating the modular support 7 in this embodiment is as follows:

[0032] S1: Take the slope surface 6 as the reference plane to draw the ground paving elevation line. Taking any modular support 7 as the reference, adjust the height of the liftable main body 702 of the modular support 7, and ensure that the orthographic projection line of the inclined surface 704 of the cushion block 703 falls within the elevation line;

[0033] S2: Press the lower reference ruler against the slope surface 6 beside the reference modular support 7, and ensure that the lower reference ruler is consistent with the length direction of the slope surface 6;

[0034] S3: Rotate the connecting rod 3 so that the upper reference ruler completely abuts against the inclined surface 704 of the cushion block 703 of the reference modular support 7;

[0035] S4: Use the auxiliary tool for adjusting the distance between the upper reference ruler 1 and the lower reference ruler 2 to adjust the height of the main body of other modular supports 7 and the orientation of the spacer 703 one by one.

[0036] Figure 3 The second embodiment of the present invention is shown, and the main difference from the first embodiment is that: the length of the connecting rod 3 is adjustable, and any one of the connecting rods 3 serves as the elevation reference ruler 4.

[0037] From Figure 4 It can be seen that the left connecting rod 3 serves as the elevation reference ruler 4, that is, the angle measuring structure 5 is arranged at the vertex of the lower left corner of the parallelogram structure.

[0038] During specific implementation, the elevation reference ruler 4 includes a rod sleeve 401 and a telescopic rod 402 sleeved in the rod sleeve 401. The rod sleeve 401 is hinged to the lower reference ruler 2, and the telescopic rod 402 is hinged to the upper reference ruler 1. A strip-shaped window 403 is opened along the length direction on the rod sleeve 401, a first scale 404 is arranged along the length direction on one side of the strip-shaped window 403, and a first scale mark 405 is arranged on the telescopic rod 402 corresponding to the first scale 404. An angle measuring structure 5 is arranged at any vertex of the parallelogram structure. The angle measuring structure 5 is arranged between the lower reference ruler 2 and the elevation reference ruler 4. The angle measuring structure 5 includes a second scale 501 arranged around the hinge point of the elevation reference ruler 4 and the lower reference ruler 2, and a second scale mark 502 arranged at the center of the second scale 501 and rotating with the elevation reference ruler 4.

[0039] As Figure 5 and Figure 6 shown, based on the above structure, the second embodiment also discloses a ground paving slope-finding structure, including a slope 6 with an inclination of θ arranged at the bottom of the precast caisson main body and modular supports 7. The modular supports 7 include a base 701 embedded in the bottom of the caisson main body, a liftable main body 702 arranged on the base 701, a spacer 703 arranged on the liftable main body 702, and an inclined surface 704 with an inclination of θ arranged on the spacer 703. It also includes the auxiliary tool as claimed in the claims. The lower reference ruler 2 of the auxiliary tool realizes reference plane comparison by abutted against the slope 6 along the length direction. The upper reference ruler 1 of the auxiliary tool is aligned with the ground paving elevation line. When the modular support 7 is calibrated, the upper reference ruler 1 of the auxiliary tool is completely abutted against the inclined surface 704 of the modular support 7.

[0040] In this embodiment, the height of the modular support 7 can be calibrated by two methods. Refer to Figure 5 , and the specific steps of one of the methods are:

[0041] S1’: Set the ground paving elevation line with the slope surface 6 as the reference plane, adjust the height of the elevation reference scale 4 of the auxiliary tool to h, and rotate the leveling staff so that the angle between it and the elevation reference scale 4 remains at 90°, where h is the height value of the ground paving elevation line on the reference plane;

[0042] S2’: Place the lower leveling staff of the auxiliary tool against the slope surface 6 beside the modular support 7, and ensure that the lower leveling staff is aligned with the length direction of the slope surface 6, and keep the elevation reference scale 4 perpendicular to the slope surface 6;

[0043] S3’: Adjust the height of the liftable main body 702 of the modular support 7 and the orientation of the cushion block 703 until the inclined surface 704 of the cushion block 703 is completely in contact with the upper leveling staff of the auxiliary tool;

[0044] S4’: Repeat steps S2’ - S3’ to complete the elevation adjustment of the liftable main body 702 of all modular supports 7 and the orientation adjustment of the cushion blocks 703 one by one.

[0045] Refer to Figure 6 , and the specific steps of another method are as follows:

[0046] S1”: Set the ground paving elevation line with the slope surface 6 as the reference plane, and use any modular support 7 as a reference to adjust the height of the main body of the modular support 7, and ensure that the orthogonal projection line of the inclined surface 704 of the cushion block 703 falls within the elevation line;

[0047] S2”: Adjust the angle between the lower leveling staff of the auxiliary tool and the left elevation reference scale 4 to 90° - θ, place the lower leveling staff against the slope surface 6 beside the reference modular support 7, ensure that the lower leveling staff is aligned with the length direction of the slope surface 6, and pay attention to keeping the elevation reference scale 4 in a vertical state;

[0048] S3”: Adjust the height of the elevation reference scale 4 of the auxiliary tool so that the upper leveling staff is completely in contact with the inclined surface 704 of the cushion block 703;

[0049] S4”: Use the auxiliary tool with the set angle and height to adjust the height of the main bodies of the other modular supports 7 and the orientation of the cushion blocks 703 one by one.

[0050] In summary, the auxiliary tool of the present utility model can quickly and accurately achieve parallel slope finding for ground paving, ensuring the parallelism and flatness of the ground paving. In practical applications, the operator only needs to place the lower ruler 2 of the auxiliary tool against the slope 6 at the bottom of the caisson main body along the length direction, and then adjust the length or angle of the connecting rod 3 to align the upper ruler 1 with the ground paving elevation line. At this time, the height of the modular support 7 can be calibrated according to the indication of the auxiliary tool to ensure that the heights of all modular supports 7 are the same; since the auxiliary tool adopts a parallelogram structure, the relative position between the upper ruler 1 and the lower ruler 2 can be conveniently adjusted to adapt to different slopes and ground paving requirements. At the same time, by setting the angle measuring structure 5 and scale markings, the operator can more intuitively understand the angle and length changes of the connecting rod 3, so as to more accurately control the height of the modular support 7; the auxiliary tool of the present utility model has the advantages of simple structure, easy operation, time-saving and labor-saving, and high precision. With the cooperation of the slope 6 at the bottom of the caisson main body and the liftable main body 702 of the modular support 7, the construction efficiency and quality of parallel slope finding for precast caissons can be significantly improved.

Of course, the scope of rights of the present utility model cannot be limited by this.
