TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a curtain wall plate type embedded part construction method and fixing buckle. BACKGROUND

[0002] In the field of building engineering, as the outer envelope structure of the building, the construction quality of the curtain wall directly affects the safety, aesthetics and functionality of the building. The curtain wall plate type embedded part is an important component for connecting the curtain wall and the main structure, and the installation position and precision of the embedded part are crucial to the stability and reliability of the curtain wall.

[0003] Common embedded parts include embedded plates and connecting ribs, and the connecting ribs are vertically and fixedly arranged on the surface of the embedded plate. In the existing construction of curtain wall plate type embedded parts in building engineering, the connecting ribs are usually fixed with the reinforcing bars of the main structure. However, the precision control of the embedded part is a difficulty in construction, especially in the case of cross construction with reinforcing bar engineering and formwork engineering, the embedded part will be affected by the subsequent process and deviate, especially before pouring the beam column concrete, in order to ensure the thickness of the concrete protective layer, the traditional construction process is to adjust the beam column reinforcing bar after the embedded part is bound with the beam column reinforcing bar.

[0004] However, in the process of adjustment, the position of the embedded plate fixed on the beam column reinforcing bar in advance will be affected, and after the adjustment of the beam column reinforcing bar, the position of the embedded plate will also change, which cannot meet the design and specification requirements, and thus quality problems will occur. SUMMARY

[0005] In order to solve the problem of displacement of the embedded plate caused by the adjustment of the reinforcing bar in the traditional embedded part construction, and improve the positioning precision of the embedded part, the present application provides a curtain wall plate type embedded part construction method and fixing buckle.

[0006] In the first aspect, the present application provides a curtain wall plate type embedded part construction method adopting the following technical scheme: comprising the following steps: S1, marking the preset position of each embedded plate on the formwork; S2, detachably connecting the connecting ribs of all embedded parts to the beam column reinforcing bar; S3, detecting the consistency of the height position of all embedded plates and the perpendicularity of the surface of each embedded plate, and adjusting the unqualified embedded parts; S4, sending the embedded parts into the formwork together with the beam column reinforcing bar; S5, adjusting the position of the beam column reinforcing bar; S6, loosening the connection between the connecting rib and the beam column reinforcing bar, and adjusting the position of the embedded part, so that the embedded plate abuts against the formwork and is aligned with the preset position; S7, measuring and correcting the perpendicularity of the embedded plate again; S8, final fixation is carried out to the embedded part.

[0007] By adopting the above technical scheme, the connecting rib of the embedded part is initially connected to the beam column steel bar, and after the position of the beam column steel bar is adjusted, the connection is loosened to adjust the position of the embedded part again, so that the influence of the adjustment of the beam column steel bar on the position of the embedded part is avoided as much as possible, and the final position of the embedded plate is ensured to be strictly aligned with the preset mark in combination with the multiple measurements in S3 and S7 and the operation of abutting the embedded plate against the formwork, so that the installation position accuracy of the embedded part is ensured, thereby improving the stability and reliability of the curtain wall and reducing the generation of quality problems.

[0008] Optionally, in the S1, the marking method of the preset position is that a same ruler is used to measure with the axis of the construction control point as a reference, and dot marks are sequentially marked on the horizontal edge of the formwork to determine the horizontal position of each embedded plate.

[0009] By adopting the above technical scheme, the axis of the construction control point is used as a reference, and a same ruler is used to measure, so that the unity and accuracy of the measurement reference are ensured, the measurement error is reduced, and the horizontal position of the embedded plate is more accurately determined, thereby laying a foundation for the accurate positioning and installation of the embedded part.

[0010] Optionally, in the S3, an infrared laser level is used to measure and mark the height positions of all the embedded plates.

[0011] By adopting the above technical scheme, the infrared laser level has the characteristics of fast and accurate measurement, can more efficiently measure and mark the height positions of all the embedded plates, improves the construction efficiency, and ensures the consistency of the height positions of the embedded plates, thereby ensuring the construction quality.

[0012] Optionally, in the S3 and the S7, a level is used to measure the perpendicularity of the embedded part.

[0013] By adopting the above technical scheme, the level is easy to operate, can intuitively detect the perpendicularity of the embedded part, facilitates the construction personnel to timely find problems and make adjustments, and the level has a small structure, and in the S7, can be used in the gap between the beam column steel bar and the formwork, so that the perpendicularity of the embedded part installation meets the design and specification requirements.

[0014] Optionally, if the embedded part is located at the upper part of the side of the beam column steel bar, and the distance between the beam column steel bar and the embedded plate in the S6 can be used for the activity of a screwdriver, then in the S8, the embedded plate is fixed on the formwork by the screw through the screwdriver.

[0015] By adopting the technical scheme, the screw fixing has the characteristics of firm connection and convenient disassembly, and in the case that the spacing is allowed, the pre-embedded plate is fixed on the formwork by using the screw, so that the stability of the pre-embedded part and the formwork can be ensured, and the possibility of offset of the pre-embedded part during subsequent pouring can be prevented.

[0016] Optionally, if the pre-embedded part is located at the upper part of the beam column reinforcement side, and the spacing between the beam column reinforcement and the pre-embedded plate is insufficient for the screwdriver to move in the S6, the pre-embedded plate is pressed tightly on the formwork by the crowbar, and the connecting rib is spot-welded on the beam column reinforcement in the S8.

[0017] By adopting the technical scheme, in the case of insufficient spacing, the pre-embedded plate is pressed tightly by the crowbar and the connecting rib is spot-welded, so that the space limitation can be overcome, the pre-embedded part can be firmly fixed, the displacement of the pre-embedded part during subsequent construction process can be prevented as much as possible, and the construction requirements can be met.

[0018] Optionally, the screwdriver is an outward soft shaft screwdriver.

[0019] By adopting the technical scheme, the outward soft shaft screwdriver can be operated in a narrow space, breaking through the limitation of the traditional screwdriver on the operation space, and the screw fixing operation can be conveniently performed in the case that the spacing between the beam column reinforcement and the pre-embedded plate is small, so that the construction efficiency is improved.

[0020] Optionally, if the pre-embedded part is located at the lower part of the beam column reinforcement side, the connecting rib is connected to the beam column reinforcement by the fixing buckle in the S2, the fixing buckle is used to allow the relative displacement of the connecting rib and the beam column reinforcement when subjected to an external force, and the external force is applied to the pre-embedded part by the crowbar and the strong magnet in the S6 to adjust the position of the pre-embedded part.

[0021] By adopting the technical scheme, when the pre-embedded part is located at the lower part of the beam column reinforcement side, due to the space limitation, the screwdriver, pliers and other common traditional tools are difficult to extend, and the traditional connection method is difficult to operate and adjust. The fixing buckle allows the relative displacement of the connecting rib and the beam column reinforcement when subjected to an external force, and the external force is applied by the crowbar and the strong magnet, so that the position of the pre-embedded part can be finely adjusted up and down and left and right, without the need for complex disassembly and re-fixing operation, the construction convenience and efficiency are improved, and the accuracy of the position adjustment of the pre-embedded part is ensured, so that the pre-embedded part can be installed to the preset position.

[0022] In a second aspect, the fixing buckle provided by the present application adopts the following technical scheme: Two sleeves are included, an opening is provided through the side wall of the sleeve in the axial direction, the opening penetrates the inner and outer side walls of the sleeve, the side walls of the two sleeves away from the opening are fixed to each other, the axes of the two sleeves are skew lines, and the planes in which the axes of the two sleeves are perpendicular to each other.

[0023] By adopting the technical scheme, the connecting rib and the beam column rib can pass through different sleeves respectively, the opening enables the inner diameter of the sleeve to change by a proper range to change the clamping force inside, when an external force is applied, the connecting rib can displace along the axial direction of the sleeve to approach the formwork, and the beam column rib can displace along the axial direction of the sleeve to change the horizontal position of the embedded part, so as to meet the requirement of accurate adjustment of the position of the embedded part in the construction process, and the side wall of the sleeve far from the opening is fixedly connected, so that after the position adjustment is completed, the connection between the connecting rib and the beam column rib can be ensured, and the loosening or displacement of the embedded part in the subsequent construction is reduced.

[0024] Optionally, the opening has an arc less than 180 degrees in the circumferential direction of the sleeve.

[0025] By adopting the technical scheme, the opening has an arc less than 180 degrees, which not only ensures that the sleeve has enough opening space to facilitate the penetration and adjustment of the connecting rib and the beam column rib, but also maintains the structural integrity and strength of the sleeve.

[0026] In summary, the present application has at least one of the following beneficial technical effects: 1. The embedded part is preliminarily fixed, and then adjusted again after the adjustment of the beam column rib, and combined with multiple measurement corrections, the influence of the adjustment of the beam column rib on the position of the embedded part is avoided as much as possible, the final position of the embedded plate is strictly aligned with the preset mark, the installation position accuracy of the embedded part is ensured, and the stability and reliability of the curtain wall are improved; 2. Multiple fixing and adjusting methods are provided for embedded parts at different positions, such as the upper part and the lower part of the beam column rib, including screw fixing, spot welding connecting rib, using fixed buckle combined with crowbar and powerful magnet, which can overcome the space limitation and meet the requirements under different construction conditions, and improve the convenience and efficiency of construction; 3. The fixed buckle adopts a sleeve structure with two axes being skew lines and the planes being perpendicular to each other, allowing the connecting rib and the beam column rib to relatively displace when subjected to force, facilitating the adjustment of the position of the embedded part during construction, and ensuring the stability of the connection after the adjustment is completed, reducing the risk of loosening or displacement of the embedded part in the subsequent construction.

[0032] The following will be combined with the attached Figures 1-4 The application will be further described in detail.

[0033] Reference Figure 1 The embedded part 1 includes the embedded plate 11 and the connecting rib 12, and the connecting rib 12 is vertically and fixedly arranged on the surface of the embedded plate 11, in the embodiment, the connecting rib 12 is arranged as four, and the four connecting ribs 12 are distributed on the four corners of the embedded plate 11, and the embedded plate is further provided with screw holes for the screw to pass through.

[0034] The embodiment of the application discloses a curtain wall plate type embedded part construction method, which comprises a positioning marking step S1, a preliminary connection step S2, a detection adjustment step S3, a mold entering step S4, a reinforcement adjustment step S5, an embedded part 1 adjustment step S6, a re-correction step S7 and a final fixing step S8.

[0035] Reference Figure 2 The positioning marking step S1 marks the preset position of each embedded plate 11 on the formwork 3. Specifically, the marking method of the preset position is that the axis of the construction control point is used as a reference, a same ruler is used for measurement, the ruler is straightened along the horizontal direction, and the horizontal positioning of each embedded plate 11 is determined by sequentially marking points on the horizontal edge of the formwork 3 according to the scale of the ruler.

[0036] The preliminary connection step S2 preliminarily detachably connects all the embedded parts 1 on the beam column reinforcement 2. In the embodiment, the connection between the embedded part 1 and the beam column reinforcement 2 is specifically that the connecting rib 12 is connected with the transverse rib of the beam column reinforcement 2, and the connection mode mainly adopts the way of wire binding.

[0037] The detection adjustment step S3 detects the consistency of the height positions of all the embedded plates 11 and the perpendicularity of the surfaces of the embedded plates 11, and adjusts the unqualified embedded parts 1. Specifically, the infrared laser level is used to measure and mark the height positions of all the embedded plates 11, so as to ensure that the horizontal heights of all the embedded plates 11 are consistent. The level is used for fine adjustment of the perpendicularity of the embedded parts 1, so as to improve the construction quality.

[0038] The mold entering step S4 sends the embedded part 1 into the formwork 3 together with the beam column reinforcement 2.

[0039] Reinforcement adjustment step S5, adjust the position of the beam column reinforcement 2.

[0040] Embedded part 1 adjustment step S6, loosen the connection between the connecting rib 12 and the beam column reinforcement 2, so that the connecting rib 12 and the transverse rib of the beam column reinforcement 2 can move relatively. And adjust the position of the embedded part 1, push the embedded part 1 to the formwork 3, the embedded part 1 moves along the axis direction of the connecting rib 12, so that the embedded plate 11 is tightly pressed on the formwork 3. Push the embedded part 1 to move along the axis direction of the transverse rib of the beam column reinforcement 2, and the embedded plate 11 is aligned with the preset position on the formwork 3.

[0041] Again correction step S7, measure and correct the perpendicularity of the embedded plate 11 again.

[0042] Final fixing step S8, final fixing of the embedded part 1.

[0043] In order to facilitate the adjustment and fixation of embedded parts 1 in different working conditions, according to the position of the embedded part 1 and the distance between the formwork 3 and the beam column reinforcement 2, it is divided into three working conditions.

[0044] Working condition one: the embedded part 1 is located in the upper part of the side of the beam column reinforcement 2, and the distance between the beam column reinforcement 2 and the embedded plate 11 can be used for screwdriver activity. The screwdriver here can be selected as an outward soft shaft screwdriver, which has the characteristics of flexibility and can operate in narrow space. In the final fixing step S8, the embedded plate 11 is fixed on the formwork 3 by screw, and the screw is self tapping screw.

[0045] Working condition two: the embedded part 1 is located in the upper part of the side of the beam column reinforcement 2, and the distance between the beam column reinforcement 2 and the embedded plate 11 is not enough for screwdriver activity, then the embedded plate 11 is pressed on the formwork 3 by crowbar, and after the perpendicularity of the embedded plate 11 is measured and qualified, the connecting rib 12 is spot welded on the beam column reinforcement 2.

[0046] Reference Figure 2 With Figure 3 , working condition three: the embedded part 1 is located in the lower part of the side of the beam column reinforcement 2, at this time the welding rod, pliers, screwdriver and other tools cannot reach the embedded part 1 in the lower part of the beam column reinforcement 2, so in the preliminary connection step S2, instead of using wire binding, the connecting rib 12 is connected to the beam column reinforcement 2 by using the fixed buckle 4. This fixed buckle 4 is used to allow the relative displacement between the connecting rib 12 and the beam column reinforcement 2 when subjected to external force. In the embedded part 1 adjustment step S6, a crowbar is used to cooperate with a strong magnet to apply external force to the embedded part 1, so as to adjust the position of the embedded part 1.

[0047] The fixing buckle 4 comprises two sleeves 41, and an opening 42 is formed through the side wall of the sleeve 41 in the axial direction and penetrates the inner and outer side walls of the sleeve 41. The side walls of the two sleeves 41 on the side away from the opening 42 are fixed to each other, the axes of the two sleeves 41 are skew lines, and the planes where the axes of the two sleeves 41 are located are perpendicular to each other.

[0048] In the embodiment, the two sleeves 41 of the fixing buckle 4 are integrally formed, and a plurality of fixing buckles 4 can be prepared for standby in order to facilitate the spacing between the connecting rib 12 and the beam column steel bar 2. The fixing buckles 4 in different embodiments are different in that the spacing between the two sleeves 41 is different. The height position of the embedded plate 11 is adjusted in the detection and adjustment step S3 in the manner of replacing the fixing buckle 4. The sleeve 41 is used to accommodate and tightly hold the connecting rib 12 or the beam column steel bar 2. In the embodiment, the connecting rib 12 or the beam column steel bar 2 is preferably a threaded steel bar, so as to increase the sliding resistance of the sleeve 41 on the steel bar.

[0049] The material of the sleeve 41 can be high-strength plastic, which has the advantages of light weight, corrosion resistance and high strength, and can meet the use requirements in the construction process. The opening 42 has an arc less than 180 degrees in the circumferential direction of the sleeve 41, so as to ensure that the sleeve 41 has sufficient holding force when fixing the connecting rib 12 and the beam column steel bar 2, and prevent the connecting rib 12 and the beam column steel bar 2 from being pulled out of the sleeve 41. In the embodiment, the opening 42 has an arc of 90 degrees in the circumferential direction of the sleeve 41.

[0050] The implementation principle of the construction method of the fixing buckle 4 in the embodiment is that, when the fixing buckle 4 is installed, one of the sleeves 41 is sleeved on the connecting rib 12 from the opening 42, and the other sleeve 41 is sleeved on the beam column steel bar 2 from the opening 42. In the embedded part 1 adjustment step S6, when the embedded part 1 is pushed to be close to the formwork 3, one of the sleeves 41 slides on the connecting rib 12, so that the embedded plate 11 is tightly pressed against the formwork 3; when the embedded plate 11 of the embedded part 1 is aligned with the preset position on the formwork 3, the other sleeve 41 slides on the cross rib of the beam column steel bar 2.

[0051] The embodiments of the specific implementation mode are the preferred embodiments of the application, and are not intended to limit the protection scope of the application. The same parts are indicated by the same reference numerals. Therefore, equivalent changes made according to the structure, shape and principle of the application should be covered by the protection scope of the application.
