Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to an auxiliary mechanism for calibrating the installation position of composite floor slabs. Background Technology

[0002] As a key component in prefabricated concrete structures, the installation accuracy of composite floor slabs directly affects the overall construction quality and the smooth progress of subsequent processes. Currently, the construction of composite floor slabs typically relies on manual measurement and layout combined with visual inspection for positioning control, depending on the experience of on-site workers to determine the slab edge positions. This method is not only inefficient but also prone to misalignment and displacement, resulting in uneven slab joints and irregular edges, affecting the structural integrity and aesthetic quality, and increasing the risk of rework.

[0003] In response to the control requirements of composite floor slabs during hoisting and positioning, some projects have attempted to use simple baffles or limiting devices to constrain the edges of the slabs. However, these devices generally have poor applicability and weak adjustment capabilities, and cannot meet the rapid adjustment requirements of floor slabs of various specifications and sizes. In particular, they cannot accurately control the position of the slab edges under complex working conditions, and still rely on repeated measurements and adjustments, making it difficult to guarantee construction efficiency and accuracy.

[0004] Therefore, there is an urgent need for an auxiliary device that is simple in structure, easy to operate, accurate in positioning, and adaptable to composite floor slabs of different specifications. This device should be able to quickly set the installation boundary before hoisting, effectively guide the floor slabs into place during hoisting, reduce manual measurement intervention, improve installation accuracy, ensure construction quality, and meet the diverse installation needs of composite floor slabs.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Example 1:

[0037] Please see Figure 1 , 2 1, 2, 3, 4, 10, 11 and 12, this utility model provides a technical solution:

[0038] Specifically, a composite floor slab installation position calibration auxiliary mechanism includes a calibration position 1. The calibration position 1 includes a beam template 11 with a formed bottom, a composite floor slab 12 with a top of the beam template 11, and an auxiliary device with both sides clamping the inner top of the beam template 11. The upper top surface of the auxiliary device coincides with the expected installation position of the composite floor slab 12. The auxiliary device includes an auxiliary device 2, which includes a fixing member 21 and a positioning member 24. A support screw 4 is provided between the fixing member 21 and the positioning member 24. The support screw 4 passes through the outer side of the positioning member 24 and is screwed with an anti-loosening nut 6. The outer side of the support screw 4 is screwed with the outer surface of the positioning member 24 and a positioning nut 5. One end of the support screw 4 is fixed to the fixing member 21.

[0039] Specifically, the top of the fixing component 21 is integrally formed with a positioning claw 22, and the top of the positioning component 24 is integrally formed with a positioning claw 25.

[0040] Specifically, the height of positioning claw 1 22, positioning claw 25, positioning claw 36 and positioning claw 4 37 is at least one-third of the thickness of the composite floor slab 12.

[0041] Specifically, the outer surface of the support screw 4 is provided with size scale lines.

[0042] Auxiliary device 12 is used for positioning assistance before the installation of composite floor slabs 12. By being installed inside the beam formwork 11, it marks the installation boundary of the composite floor slab, facilitating control of the slab edge position and improving hoisting accuracy. The specific usage procedure is as follows:

[0043] 1. Measurement and layout

[0044] Before hoisting the composite floor slab 12, surveyors laid out control lines, edge lines, and center lines on the beam formwork 11 according to the construction drawings, and checked whether the flatness and elevation of the beam surface met the construction requirements. If necessary, shims were used for local leveling to provide a reliable benchmark for hoisting.

[0045] 2. Installation of Auxiliary Device One

[0046] According to the design dimensions and layout position of the composite floor slab 12, auxiliary device 2 is installed inside the beam formwork 11.

[0047] The auxiliary device 2 includes components such as a fixing component 21, a positioning component 24, a support screw 4, a positioning nut 5, and an anti-loosening nut 6.

[0048] The distance between the fixing member 21 and the positioning member 24 is adjusted by the support screw 4, and they are clamped inside the beam formwork 11 to set a reference position for forming the boundary of the composite floor slab 12, which serves as the control basis for subsequent hoisting.

[0049] 3. Lifting and positioning of composite floor slabs

[0050] After the auxiliary device 12 is installed, the hoisting operation of the composite floor slab 12 is carried out according to the measurement and layout.

[0051] During the hoisting process, the composite floor slab 12 is slowly lowered above the beam formwork 11, and the edge of the slab is adjusted to align with the layout position using the boundary position determined by the auxiliary device 2 as a reference before it is put into place.

[0052] 4. Review and Adjustment

[0053] After the composite floor slab 12 is hoisted into place, its position is checked to ensure that the edges, center line, joint width, and elevation of the slab meet the design requirements. If any deviations are found, the floor slab position is adjusted by re-hoisting until it meets the standards.

[0054] 5. Follow-up work

[0055] After the composite floor slab 12 is hoisted and passes inspection, the auxiliary device 12 is removed, the beam formwork 11 and the working surface are cleaned, and subsequent procedures such as rebar tying and concrete pouring are carried out.

[0056] Through the above steps, the auxiliary device 12 provides effective boundary marking and position guidance during the installation of the composite floor slab, which helps to control the position of the slab edge, improve the accuracy of hoisting and installation and construction efficiency. Compared with the existing technology of visual adjustment, the limiting method with positioning claw structure has reliable performance and plays a role in restricting and indicating the edge of the floor slab during the falling process of the precast floor slab 12.

[0057] Auxiliary device 12 is mainly suitable for scenarios where the width of cast-in-place beams is relatively uniform and the installation position of composite floor slabs 12 is also very uniform throughout the construction process of the entire project. It has the advantages of being simple and effective, low cost, easy to maintain, easy to operate, intuitive indicative, and high precision.

[0058] The height of positioning claw 1 22 and positioning claw 25 is at least one-third of the thickness of the composite floor slab 12, but preferably twice the thickness of the composite floor slab 12, so that they can directly guide the fall to the accurate position during the descent.

[0059] Example 2:

[0060] Please see Figure 1 , 2 5, 6, 7, 8, 9, 13 and 14, this utility model provides a technical solution: an auxiliary mechanism for calibrating the installation position of a composite floor slab, including a calibration position 1, the calibration position 1 including a beam template 11 formed at the bottom, a composite floor slab 12 set at the top of the beam template 11, an auxiliary device set at the top of the beam template 11, the two sides of the auxiliary device clamping the inner side of the top of the beam template 11, and the upper surface of the top of the auxiliary device coinciding with the expected installation position of the composite floor slab 12.

[0061] This utility model provides a calibration auxiliary mechanism for the installation position of composite floor slabs with auxiliary devices. In use, after setting up the beam template 11, the selected auxiliary device is placed on the inner top of the beam template 11. The top plane of the auxiliary device is adjusted to coincide with the expected installation position of the composite floor slab 12. Then, the composite floor slab 12 is hoisted and placed on both sides of the auxiliary device to guide the composite floor slab 12 to fall to the accurate position. This effectively solves the problem of repeated hoisting operations caused by hoisting errors, or even rework caused by low accuracy, thus improving installation efficiency and construction quality.

[0062] Specifically, the auxiliary device also includes auxiliary device 2 3, which includes a fixing member 2 31 and a positioning member 2 34. The top of the fixing member 2 31 and the positioning member 2 34 are respectively equipped with a sliding positioning plate 39 that can be adjusted. The inner side of the fixing member 2 31 is equipped with a support screw 4. The other end of the support screw 4 is inserted into the interior of the positioning member 2 34 and screwed with an anti-loosening nut 6. The support screw 4 and the outer side of the positioning member 2 34 are screwed with a positioning nut 5.

[0063] In use, the screw connection between the positioning nut 5 and the support screw 4 is such that after the fixing part 2 31 and the positioning part 2 34 are in close contact with the inner side of the beam template 11, the positioning nut 5 is screwed outward, so that it can be supported outward on the inner side of the fixing part 2 31 and the positioning part 2 34, thus achieving the positioning effect. The height of the fixing part 2 31 and the positioning part 2 34 is set by a level and other measuring rulers before clamping and tightening. The contact position between the fixing part 2 31 and the positioning part 2 34 and the lower surface of the composite floor slab 12 is the bottom plane of the positioning claw 3 36 and the positioning claw 4 37.

[0064] Specifically, a hinge joint 32 is welded to the inner side of the fixing part 31 and the positioning part 34. A hook 33 is assembled inside the hinge joint 32, and a fixing nut 35 is screwed through the hinge joint 32.

[0065] The main purpose of hook 33 is to help the auxiliary device 2 3 to position itself before the composite floor slab 12 falls. When hook 33 is flipped upwards, without the fixing part 2 31 and the positioning part 2 34 clamping it on both sides, hook 33 can be directly hung on the top two sides of the beam formwork 11 (e.g., Figure 7 , Figure 8 , Figure 13 and Figure 14 As shown), initial positioning is performed. Then, the heights of the two fixing parts 31 and the positioning part 34 are measured using measuring methods. The positioning nut 5 is screwed outwards to a slightly tightened position. Finally, adjustments are made based on the measurement results, and the positioning nut 5 is screwed outwards again to complete the positioning of the auxiliary device 3. After positioning, the hook 33 is flipped inwards to the bottom (as shown). Figure 5 , Figure 6 , Figure 9 (As shown).

[0066] Specifically, the top of the fixing part 2 31 is integrally formed with a positioning claw 36, and the top of the positioning part 2 34 is integrally formed with a positioning claw 4 37. The center of the positioning claw 36 and the positioning claw 4 37 is provided with a screw hole, and an adjusting screw 38 is screwed into the inside of the screw hole. The end of the adjusting screw 38 is rotatably assembled to the non-working surface of the sliding positioning plate 39.

[0067] The rotation of the adjusting screw 38 will cause the sliding positioning plate 39 to move outward through the screw hole, thereby adjusting the inner position of the composite floor slab 12 that needs to be positioned.

[0068] Specifically, when the hook 33 is in the hooked state, the lower outer surface of the hook 33 is flush with the upper surfaces of the fixing member 31 and the positioning member 34.

[0069] Specifically, the upper surfaces of the fixing part 31 and the positioning part 34 are provided with scale lines. The scale lines can help to calculate the absolute distance between the two outermost sides of the sliding positioning plate 39 when adjusting the position of the sliding positioning plate 39, in combination with the relative size of the support screw 4. This allows us to know the accuracy of the preset distance.

[0070] The scale lines on the upper surfaces of the fixing component 2 31 and the positioning component 2 34 represent the distances from the outer surfaces of the positioning claw 36 and the positioning claw 4 37 to the outer surface of the corresponding starting positioning plate 39, calculated starting from 0.

[0071] The main calculation method includes the actual scale value on the left side of the support screw 4 and the fixing nut 5, plus the fixed distance including the thickness of the fixing part 2 31, the thickness of the positioning claw 36, etc., plus the distance between the outer side of the positioning claw 4 37 and the sliding positioning plate 39, minus the distance between the outer side of the positioning claw 36 and the outer side of the outer sliding positioning plate 39, which is the absolute distance between the two stacked floor slabs 12.

[0072] Specifically, the outer surface of the support screw 4 is provided with size scale lines.

[0073] Specifically, the hook 33 is L-shaped, and a screw is welded to the inner side of the bottom end of the hook. The screw passes through the hinge joint 32, and the outer structural length of the hook 33 is equal to two-thirds of the upper surface of the fixing part 31 or the positioning part 34. A counterweight is provided on the outer side of the hook 33 to ensure that the outer lever arm of the hook 33 can stably hook the inner device when the hook 33 is simply hooked. The length of the outer end of the hook 33 can be increased, or a counterweight can be provided to increase the lever arm. Alternatively, the hook 33 can be set as two units. An insertion hole is opened on the outer side of the cylindrical structure of the hook 33, and a spring-loaded pin is provided on the outside of the hinge joint 32 to restrict the hook 33 to two positions of 180 degrees. The hook 33 can also be clamped and fixed by tightening the fixing nut 35.

[0074] Specifically, the height of positioning claw 1 22, positioning claw 25, positioning claw 36 and positioning claw 4 37 is at least one-third of the thickness of the composite floor slab 12.

[0075] Auxiliary device 2.3 is suitable for installation and positioning of multi-specification composite floor slabs. Through a combination of components such as a sliding positioning plate, adjusting screws, and a hanging structure, it achieves precise control over the installation position of the composite floor slab, ensuring edge alignment and accurate positioning. Its specific usage steps are as follows:

[0076] 1. Measurement and layout

[0077] Before hoisting the composite floor slab 12, the construction personnel measured and laid out the control lines, edge lines, and center lines of the composite floor slab 12 on the beam formwork 11 according to the design drawings, and checked the levelness of the beam formwork 11. For local height differences, leveling was carried out by adding shims and other measures to ensure that the installation benchmark was accurate and reliable.

[0078] 2. Hanging and positioning of auxiliary device two

[0079] Based on the design dimensions and layout position of the composite floor slab 12, select the appropriate auxiliary device 2 3.

[0080] Fixing component 2 31 and positioning component 2 34 are placed on the inner walls of both sides of the beam formwork 11, and hooked to the top edge of the beam formwork 11 by hook 33, so that auxiliary device 2 3 is initially hooked and positioned, which is convenient for subsequent measurement and adjustment.

[0081] Use tools such as a level to measure the height on both sides, keep the left and right heights consistent, and ensure that the device is in a preliminary stable state.

[0082] 3. Adjustment and fixing of the support screw

[0083] After the connection is completed, rotate the support screw 4 and adjust the distance between the fixing part 31 and the positioning part 34 so that the two parts are attached to the inner side of the beam template 11 and form a clamping relationship.

[0084] By tightening the positioning nut 5, the clamping force is gradually increased to ensure the stability and reliability of the auxiliary device 2 3.

[0085] After tightening, flip the hook 33 from the hooked state to the storage position to avoid interfering with subsequent operations and to keep the device stable.

[0086] 4. Adjustment of sliding positioning plate

[0087] The auxiliary device 2 3 has a sliding positioning plate 39 on the fixing part 2 31 and the positioning part 2 34 respectively. The position of the sliding positioning plate 39 is controlled by the adjusting screw 38.

[0088] Rotate the adjusting screw 38 to drive the sliding positioning plate 39 to be finely adjusted in the horizontal direction to the design position, so as to accurately position the edge of the composite floor slab 12.

[0089] During the adjustment process, refer to the scale lines on the support screw 4 and the sliding positioning plate 39 to confirm the adjustment distance and ensure that the plate edge position and plate gap width meet the design requirements.

[0090] 5. Lifting and positioning of composite floor slabs

[0091] After the sliding positioning plate 39 is adjusted, the hoisting operation of the composite floor slab 12 is carried out.

[0092] During the hoisting process, the composite floor slab 12 is slowly lowered, and the position of the slab edge is controlled based on the position of the sliding positioning plate 39. This guides the composite floor slab 12 to be accurately positioned, ensuring that the slab edge is consistent with the measurement and layout lines, thus ensuring installation accuracy.

[0093] 6. Review and Adjustment

[0094] After the composite floor slab 12 was hoisted, the surveyors checked the position and verified whether the slab edges, center line, joint width and elevation met the design requirements.

[0095] If there is a slight deviation, the position of the sliding positioning plate 39 can be finely adjusted by adjusting the screw 38 to achieve a small-range correction and ensure that the hoisting accuracy meets the construction standards.

[0096] 7. Follow-up work

[0097] After the composite floor slab 12 is positioned and passes inspection, the auxiliary device 2 3 is removed, the beam formwork 11 and the working surface are cleaned, and subsequent procedures such as rebar tying and concrete pouring are carried out.

[0098] Through the above steps, auxiliary device 23 provides a stable and reliable positioning guarantee for the installation of composite floor slabs of different specifications through the cooperation of multiple structures such as hanging limit, screw adjustment and sliding positioning plate control. It is suitable for high-precision construction scenarios with complex working conditions and composite floor slabs of various sizes, and significantly improves construction quality and installation efficiency.
