Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and more particularly to a construction method for a pre-buried sleeve of a turnbuckle bolt cantilever scaffold. Background Art

[0002] With the rapid development of urban construction and the increasing number of high-rise and super-high-rise buildings, the construction environment has become increasingly complex. To meet the needs of structural construction and exterior decoration, cantilever steel pipe fastener external scaffolding has become widely used due to its wide adaptability, strong load-bearing capacity, and easy erection and dismantling. However, the I-beams placed on the floor of previous cantilever scaffolding are longer than the cantilever length, which not only wastes I-beam material but also brings inconvenience to subsequent construction. Therefore, a new type of basket-shaped bolt scaffolding has emerged, which not only saves I-beam material but also brings convenience to decoration construction.

[0003] At present, a composite insulation formwork has begun to be used as an exterior wall insulation formwork in some areas. It does not need to be removed after construction is completed and is used as permanent insulation of the exterior wall. The exterior wall insulation formwork and the main structure are cast at one time. After the exterior wall concrete is cast, it forms a whole with the composite insulation formwork, which is tightly combined. The service life is similar to that of the main structure, and it is not easy to have the inevitable hollowing, cracking, and falling off caused by the subsequent insulation layer.

[0004] When constructing a basket bolt scaffold, bolt holes connected to the main structure must be formed in the poured concrete. The position of the bolt holes must be accurate, and when installing the I-beam, it must be ensured that the I-beam main beam connecting plate (set using bolt holes) fits tightly with the concrete structure to prevent the I-beam from sinking and becoming unstable during scaffolding construction, causing the scaffolding to tilt and collapse.

[0005] The existing solution is to chisel the bolt holes after pouring the concrete. This method is extremely difficult, and for some construction scenarios with exterior wall insulation formwork, the presence of composite insulation formwork (composite insulation formwork is used as exterior wall formwork and has certain strength and rigidity), which further increases the difficulty of chiseling. The holes formed after chiseling are extremely irregular, and later repairs are also extremely difficult, which has a certain impact on the later quality.

[0006] Based on this, there is an urgent need for a bolt hole construction method for a basket bolt scaffold that can be applied to construction scenarios with exterior wall insulation formwork. Summary of the Invention

[0007] In view of the above problems, the purpose of the present invention is to provide a construction method for embedded sleeves of cantilevered scaffolding with basket bolts, so as to solve the problem that the existing construction method of basket bolt scaffolding cannot be applied to construction scenarios with exterior wall insulation formwork.

[0046] Before introducing the specific process of the construction method of the cantilever scaffolding with basket bolts provided by the present invention, it is necessary to first briefly explain the building structure targeted by the present invention. Figure 2 It can be seen that the exterior of the main structure 100 of the building (excluding the door and window structures) is provided with an exterior wall insulation template. After removing the exterior wall insulation template, the connection relationship between the main structure 100 and the I-beam can be revealed (e.g. Figure 1 shown).

[0047] The following is a detailed description of the process and functions of the construction method for the cantilevered scaffolding with basket bolts provided by the present invention, and the accompanying drawings. Figures 1 to 5 It can be seen that the construction method of the pre-buried sleeve of the cantilever scaffolding with a turnbuckle bolt provided by the present invention mainly includes the following steps:

[0048] Determine the installation position of the I-steel 200 to be constructed, and reserve installation holes 14 on the exterior wall insulation template 1 according to the installation position;

[0049] After the reinforcement of the main structure on site is tied and accepted, the exterior wall insulation formwork 1 is installed, and the detachable support mold 3 is installed in the installation hole 14;

[0050] A pre-buried sleeve 5 is provided on the side of the detachable support mold 3 away from the exterior wall insulation template 1; and a locking connector is provided in the pre-buried sleeve 5;

[0051] Set up a template reinforcement system on the outside of the exterior wall insulation template 1 and fix the template reinforcement system by locking connectors;

[0052] Concrete 7 is poured outside the exterior wall insulation formwork 1 based on the formwork reinforcement system;

[0053] After the concrete 7 reaches the preset strength, the formwork reinforcement system, the detachable support mold 3 and the locking connector are removed to fix the embedded sleeve 5 in the concrete 7 to form the required bolt hole.

[0054] Specifically, the process of determining the installation position of the I-beam 200 to be constructed includes:

[0055] Draw the plan layout of the turnbuckle bolt cantilever scaffolding to be constructed;

[0056] The installation position of the I-beam 200 to be constructed is determined according to the plan layout drawing.

[0057] More specifically, the process of reserving installation holes 14 on the exterior wall insulation template 1 according to the installation position includes: optimizing the layout of the exterior wall insulation template 1 according to the installation position based on the construction drawings, and then reserving installation holes 14 on the exterior wall insulation template 1 at positions corresponding to the I-beam 200 (corresponding to the installation position) when the exterior wall insulation template 1 is processed on-site according to the layout drawing of the cantilever scaffolding with basket bolts.

[0058] It should be noted that the exterior wall insulation template 1 is usually provided with several (such as Figure 2 As shown, there are at least two of them, and several exterior wall insulation templates 1 are finalized and manufactured by the factory. After production, they are layout-numbered according to size specifications; and, during the installation of the exterior wall insulation templates 1, each exterior wall insulation template 1 is installed in sequence according to the preset layout number.

[0059] In addition, it should be noted that the composite insulation formwork usually includes an outer cement-based protective layer, an alkali-resistant glass fiber mesh cloth, a transition layer, an adhesive layer, reinforcing ribs, an insulation core material, an inner cement-based protective layer and other layer structures. The total thickness is about 90 mm, and it has sufficient strength and rigidity. It can be used as an exterior wall insulation formwork 1 during construction. The exterior wall insulation formwork 1 is shaped and processed according to the layout size after optimized design. When constructing the basket bolt scaffolding, it is necessary to reserve holes corresponding to the bolt holes (i.e., installation holes 14) in advance.

[0060] After the installation of the exterior wall insulation formwork 1 is completed, a detachable support mold 3 can be produced on site. The detachable support mold 3 includes two upper and lower support plates spliced ​​together; and, installing the detachable support mold 3 in the installation hole 14 includes: respectively arranging the two support plates on the upper and lower sides of the installation hole 14, wherein the two support plates are close to the upper and lower surfaces of the installation hole 14, and a sleeve reserved hole is formed between the sides where the two support plates are close to each other, and one end of the embedded sleeve 5 is connected to the sleeve reserved hole.

[0061] In order to facilitate the later disassembly of the detachable support mold 3, the installation of the detachable support mold 3 in the installation hole 14 can also include: fixing pads 2 in contact with the exterior wall insulation formwork 1 at the corners of each support plate, and the pads 2 can be selected from iron pads and fixedly connected to the support plate by welding, so as to facilitate the removal of the mold after the later pouring of concrete 7 is completed.

[0062] After the detachable support mold 3 is installed, the embedded sleeve 5 is inserted into the reserved hole of the sleeve, the locking connector is inserted into the embedded sleeve 5, and the locking connector and the template reinforcement system are used to complete the final reinforcement and fixation.

[0063] In a specific embodiment of the present invention, in order to realize the erection of the formwork reinforcement system, the formwork reinforcement system may include a beam bottom formwork 6, a beam side wall formwork 8 and a wooden beam 9; and, in the process of erecting the formwork reinforcement system on the outside of the exterior wall insulation formwork 1, the beam side wall formwork 8 is erected on the side of the embedded sleeve 5 away from the detachable support mold 3, the beam bottom formwork 6 is erected at the bottom of the beam side wall formwork 8, and the wooden beam 9 is erected on the side of the beam side wall formwork 8 away from the embedded sleeve 5.

[0064] In another specific embodiment of the present invention, in order to achieve the locking and fixing of the locking connector and the formwork reinforcement system, the locking connector may include a tension bolt 13, a nut 12 and a fixing plate 4; wherein, the fixing plate 4 is fixed to one end of the tension bolt 13, and the nut 12 is screwed to the other end of the tension bolt 13; and, in the process of fixing the formwork reinforcement system through the locking connector, the tension bolt 13 is passed through the embedded sleeve 5; wherein, the fixing plate 4 is limited in the installation hole 14, the nut 12 is arranged on the outside of the wooden beam 9, and the end of the tension bolt 13 away from the fixing plate 4 passes through the beam side wall formwork 8 and the wooden beam 9 in turn and is screwed to the nut 12.

[0065] Furthermore, in order to further enhance the locking effect of the locking connector, the locking connector may also include a mountain-shaped fastener 11 ; and, in the process of fixing the formwork reinforcement system through the locking connector, the mountain-shaped fastener 11 is limited between the wooden beam 9 and the nut 12 .

[0066] After the formwork reinforcement system is erected and locked and fixed by the locking connector, concrete 7 is poured into the interior of the formwork reinforcement system. After the concrete 7 is poured, it is necessary to wait for a preset time. After the concrete 7 reaches the preset strength, the formwork reinforcement system, the detachable support mold 3 and the locking connector (after removal, they can be collected and reused) are removed to fix the embedded sleeve 5 in the concrete 7 to form the required bolt hole.

[0067] After the required bolt holes are formed, the subsequent construction of the cantilever scaffolding with turnbuckle bolts can be carried out based on the required bolt holes. It should be noted that the process of constructing the cantilever scaffolding with turnbuckle bolts based on the required bolt holes is the same as that of the prior art, so the specific construction process will not be repeated here.

[0068] The above description, with reference to the accompanying drawings, illustrates the method for constructing pre-embedded casings for cantilever scaffolding with turnbuckle bolts according to the present invention. However, those skilled in the art will appreciate that various modifications may be made to the method without departing from the scope of the present invention.
