Description

TECHNICAL FIELD

[0001] The application relates to the technical field of the building industry, and particularly provides a low-coupling aluminum formwork system and a construction method thereof. BACKGROUND

[0002] At present, the trend of the domestic building industry is to replace the traditional wood formwork system with an aluminum formwork system, especially for high-rise commercial housing, which is particularly suitable for aluminum formwork construction. The aluminum formwork system has the following economic and social benefits compared with the wood formwork system: 1. The aluminum formwork reduces the requirement for wood of the wood formwork, which meets the environmental protection trend; 2. The aluminum formwork is simple to assemble, and a new worker can be put on duty after simple training, which is not limited by the shortage of professional and technical personnel; 3. The labor demand is small, the dependence on machinery such as tower cranes is small, and the investment in civilized construction cost in the later period is small; 4. The aluminum formwork can be reused, and a set of system of 80% of general-purpose plates can be used in different projects, so that the formwork cost is small; 5. The effect of the fair-faced concrete can be achieved, the plastering is not needed, the materials such as cement sand are saved, and the construction period is saved.

[0003] The aluminum formwork system has its inherent advantages, but at present, the turnover of the aluminum formwork is about 70-80 times, which is far from the advantage of the service life of 300 times of the aluminum formwork design turnover. At present, the aluminum formwork system has a high technical requirement for workers, and due to the rapid growth of the application scale of the aluminum formwork, the aluminum formwork labor market has been in short supply. Moreover, due to the operation characteristics of the aluminum formwork, ordinary labor forces are put on duty after a short training of one week to one month, and the aluminum formwork assembly has a high requirement for physical quality and physical strength. A large number of young labor forces without any technical work background are poured in, the technical level of the labor forces is generally low, the technology is rough, the construction of the poor labor force team causes a high polishing and repairing cost in the later period, even up to one third of the aluminum formwork leasing cost, the requirement for the management force is high, and the energy of the management team is quite large.

[0004] The stress in the current market aluminum formwork system assembly process is quite large, especially in the labor market assembly level can not keep up with the aluminum formwork specification. Aluminum formwork system supporting construction specification in the actual construction process is difficult to better implement, the most difficult to implement is after the wall column formwork installation is completed, the aluminum form is adjusted first, and then the beam and keel are installed. The reason for this is that after the wall column installation is completed, the construction party can not arrange sufficient personnel to detect the wall column one by one, and if the beam is installed after the wall column detection is completed, it is not conducive to the construction period. Once it cannot be detected one by one, when the beam and keel are assembled under the condition that the wall column is not qualified, the aluminum form will be assembled and the stress between the aluminum forms will be large, even plastic deformation will occur, and it will be accumulated layer by layer. The forming size of the assembled formwork is increasing, which exceeds the original positioning size, and the vicious cycle is that the more you try to install, the more deformed it is. The quality of the finished concrete is getting worse and worse.

[0005] Moreover, the key to aluminum form construction is management, and the control of construction precision in the management process is the key. When the construction party does not have enough strength and management force, the construction precision often exceeds the requirements of the aluminum form construction specification. At the same time, the control of aluminum form construction precision exists in each link of construction: 1. Precision control in the measurement and setting-out stage; 2. Positioning precision of positioning rib welding; 3. Precision control and deviation direction control of wall column verticality during wall column installation; 4. Overall qualified rate control in the adjustment stage.

[0006] For example, in a room, the positioning rib of the left wall column deviates 5 mm to the right relative to the line, and the line also deviates 5 mm to the right relative to the control axis, and at the same time, the wall also deviates 5 mm to the right during installation. Separately, each precision is within the allowable range of the specification, but the result is that the upper end of the wall deviates 15 mm relative to the control axis. At this time, if the right wall deviation is the mirror image of the left wall deviation, the plate installation space between the two walls will be reduced by 3 cm. It can be imagined that such a large deviation cannot be solved in the traditional adjustment, and because of the effort to adjust, the verticality of the adjacent wall is also affected, which cannot meet the verticality precision requirement.

[0007] The current construction specification of aluminum formwork requires that each stage reaches the corresponding accuracy, and the actual construction on site is also the same, if the management manpower lacks tracking and rechecking of each link, it can only rely on the technical level and mood of the workers (which depends on the market price of aluminum form installation) and the limitation is particularly large. Therefore, either a large number of technical personnel are invested to do these things without much technical content, or the price of aluminum form installation is greatly increased, or high-quality aluminum formwork systems (larger stiffness, more accurate, and less deformation) are purchased at high prices. The cost of the three schemes is high, and it can be said that the work is doubled and the result is halved. This is the congenital defect of the current aluminum formwork, which is also the reason for the development bottleneck of the current aluminum form system.

[0008] If the accuracy control of the first and second stages can be solved at a certain cost, the accuracy control of the third and fourth stages is not so simple, because at this time the accuracy control is no longer a simple point and line control. Due to the high accuracy requirement of each component of the aluminum form, the whole body is affected by a single hair, the left accuracy meets the requirement, the right accuracy meets the requirement, and the accuracy of the middle joint does not meet the requirement. The accumulation of errors in multiple rooms is inevitable. These two stages often reflect the technical level of the aluminum form labor team, and this technical barrier is not easy to break, which requires a lot of time to accumulate technology and a suitable unit price level to cultivate. The current aluminum labor market is the highest in liquidity. Especially the low-end aluminum team, the composition of personnel is completely random, and they are recruited as long as they can do it.

[0009] In short, there is a great conflict between the current aluminum formwork system and the current aluminum labor market in terms of technical level, which puts high requirements on the management level of enterprises and the level of labor teams. This contradiction cannot be broken through as a whole, which makes the development of aluminum formwork encounter a bottleneck. SUMMARY

[0037] Please refer to Figure 1 The low-coupling aluminum formwork system provided by the embodiment of the present application comprises a wall aluminum formwork, a beam aluminum formwork, a floor aluminum formwork, a connecting piece connecting adjacent aluminum formworks, a fastener locking the connecting piece, and a support assembly supporting the aluminum formwork, and further comprises an adjusting pad assembly 10, which comprises a plurality of wall adjusting pads with different thicknesses, a plurality of beam adjusting pads with different thicknesses, and a plurality of floor adjusting pads 11 with different thicknesses. Among them, the wall adjusting pad, the beam adjusting pad and the floor adjusting pad 11 are only different in width, so they are not shown here.

[0038] In the embodiment, the floor aluminum formwork, the wall aluminum formwork and the beam aluminum formwork have the same structure as the aluminum formwork in the prior art, which is not shown here. Figure 1 A plurality of floor adjusting pads 11 with different thicknesses are shown, wherein the thickness specifications of the plurality of floor adjusting pads 11 can be 1mm, 3mm, 5mm and 10mm. The adjusting pad of each thickness can be one or more. Of course, the floor adjusting pad 11 can also have other thicknesses. When the thickness specifications are more, the flexibility is better when the floor adjusting pads 11 with different thicknesses are combined arbitrarily on site. Similarly, the thickness specifications of the plurality of beam adjusting pads are 1mm, 3mm, 5mm or 10mm; the thickness specifications of the plurality of wall adjusting pads are 1mm, 3mm, 5mm or 10mm.

[0039] It should be noted that a small notch of a certain size is arranged at the corner of each adjusting pad to distinguish the wall adjusting pad, the beam adjusting pad and the floor adjusting pad 11. The notch can be a triangular notch or a right-angle notch, etc.

[0040] Further, according to the characteristics of the floor ceiling, the floor adjusting pad 11 comprises a transverse floor adjusting pad and a longitudinal floor adjusting pad, the length of the transverse floor adjusting pad is consistent with the length of the floor aluminum formwork, and the longitudinal floor adjusting pad is composed of two combined pads, and the combined length of the two combined pads is consistent with the length of the floor aluminum formwork.

[0041] In this embodiment, the adjusting base plate assembly comprises a plurality of wedge-shaped adjusting plates and a plurality of L-shaped corner connecting plates fixed to the aluminum formwork at the corners.

[0042] Referring to Figure 2 , Figure 3 The embodiment of the present application also provides a method for building the low-coupling aluminum formwork system, comprising the following steps:

[0043] S1, prefabricating an adjusting base plate assembly 10, wherein the adjusting base plate assembly 10 comprises a plurality of wall adjusting base plates with different thicknesses, a plurality of beam adjusting base plates with different thicknesses, and a plurality of floor adjusting base plates 11 with different thicknesses.

[0044] Specifically, before the adjusting base plate assembly 10 is made, a conventional aluminum formwork assembly drawing is designed according to a structural design drawing, and appropriate adjusting strips are arranged on the conventional assembly drawing, wherein the width of each adjusting strip is about 1 cm, one or more horizontal adjusting strips and one or more vertical adjusting strips are arranged in each room according to the span, and each adjusting strip is arranged along the front of the aluminum formwork joint, the adjusting strip divides the aluminum formwork along the way, and the position of the adjusting strip is filled by the adjusting base plate assembly. Each adjusting strip extends in one way, and when the adjusting strip encounters a discontinuous joint, the adjusting strip is translated to the adjacent parallel joint, and when the adjusting strip encounters a wall or a beam, adjusting strips are also arranged at the corresponding positions of the wall formwork and the beam formwork, and adjusting strips are also arranged on the two side formworks of the wall and the beam and the ground formwork. According to the different positions and shapes of the adjusting strips, the adjusting base plate assembly 10 that is suitable for the side of the aluminum formwork is prefabricated.

[0045] In this step, the prefabricated adjusting base plate assembly 10 is the aforementioned adjusting base plate assembly 10, which is not described here.

[0046] S2, installing the wall aluminum formwork 30 of the outer shear wall along the fixed positioning steel bars, adjusting the perpendicularity of the wall aluminum formwork 30 to be within a preset range, and locking the back beads;

[0047] Specifically, in this step, the wall aluminum formwork 30 is formed by a plurality of walls that are connected to each other, and the adjacent two wall aluminum formworks 30 are connected by a connecting piece (not shown in the figure) and locked and fixed by a fastener. This step is the same as the prior art, and will not be described in detail here. After the wall is installed, the perpendicularity of the wall needs to be adjusted to ensure that the perpendicularity is within a preset range, and the preset range is 0-2mm outward, and then the back beads are installed, and the perpendicularity of the aluminum formwork is adjusted again.

[0048] S3, installing the beam aluminum formwork 40 on the wall aluminum formwork 30;

[0049] When the wall aluminum formwork 30 is installed, the beam aluminum formwork 40 is installed on the top of the wall aluminum formwork 30, and this step is also the same as the prior art, and will not be described here.

[0050] S4, installing floor aluminum formwork 20 on beam aluminum formwork 40, reserving transverse adjustment zone 50 and longitudinal adjustment zone 60 with certain width in transverse and longitudinal direction of floor aluminum formwork 20 respectively;

[0051] Specifically, in this step, first, selecting suitable position for transverse adjustment zone 50 and longitudinal adjustment zone 60 in transverse and longitudinal direction of floor aluminum formwork 20. In this embodiment, the size of certain floor aluminum formwork 20 needs to be reduced by about 1cm in transverse and longitudinal direction, as adjustment space of adjustment zone, therefore the width of transverse adjustment zone 50 and longitudinal adjustment zone 60 ranges from 0 to 1cm.

[0052] The setting position of transverse adjustment zone 50 and longitudinal adjustment zone 60 is not at the aluminum formwork with reduced size, in this embodiment, transverse adjustment zone 50 is preferably set at the floor aluminum formwork 20 adjacent to keel 70. Bolt connection is adopted between two floor aluminum formwork 20 at selected transverse adjustment zone 50, and the length of bolt is first adjusted to 1cm. The two floor aluminum formwork 20 connected by bolt is not tightly connected, and there is adjustment space, when adjusting the perpendicularity of wall aluminum formwork 30 in left-right symmetry, the transverse adjustment zone 50 as shown in Figure 3 is formed between the two floor aluminum formwork 20. Similarly, bolt connection is adopted between two floor aluminum formwork 20 at selected longitudinal adjustment zone 60, and the length of bolt is first adjusted to 1cm. The two floor aluminum formwork 20 connected by bolt is not tightly connected, and there is adjustment space, when adjusting the perpendicularity of wall aluminum formwork 30 in front-back symmetry, the longitudinal adjustment zone 60 as shown in Figure 3 is formed between the two floor aluminum formwork 20.

[0053] S5, adjusting the perpendicularity of wall aluminum formwork 30 in left-right symmetry, so that the width of each point of transverse adjustment zone 50 is within the preset suitable range, since the adjustment pad has not been installed at this time, the adjustment of the perpendicularity of each wall is relatively independent, if the adjustment of certain wall exceeds the permissible range of perpendicularity, the perpendicularity of adjacent wall can be adjusted to achieve the purpose of making the width of plate adjustment zone consistent, adjusting the wall formwork of all rooms in the order of room from outside to inside, adding floor adjustment pad 11 with different thickness into transverse adjustment zone 50 piece by piece, so that the floor adjustment pad 11 is tightly matched with adjacent floor aluminum formwork 20, and the pin is locked; adjusting the perpendicularity of wall aluminum formwork 30 in front-back symmetry, so that the width of each point of longitudinal adjustment zone 60 is within the preset suitable range, adding floor adjustment pad 11 with different thickness into longitudinal adjustment zone 60 piece by piece, so that the floor adjustment pad 11 is tightly matched with adjacent floor aluminum formwork 20, and the pin is locked; finally, installing beam adjustment pad and wall adjustment pad, and locking the pin.

[0054] In actual adjustment, due to the difference in the perpendicularity of the left and right wall surface aluminum formworks 30, the transverse adjustment zone 50 is inclined, that is, the width of each point of the transverse adjustment zone 50 is inconsistent, at this time, the perpendicularity of the left and right wall surface aluminum formworks 30 needs to be continuously adjusted symmetrically, for example, the left wall surface aluminum formwork 30 is adjusted to the right by a certain amount, and the right wall surface aluminum formwork 30 is adjusted to the left by a certain amount, so that the transverse adjustment zone 50 located on one side of the keel 70 is perpendicular to the floor aluminum formwork 20, that is, the width of each point of the transverse adjustment zone 50 remains consistent, at this time, the width of the transverse adjustment zone 50 is measured, and a plurality of floor adjustment pads 11 with different thicknesses are added into the transverse adjustment zone 50 piece by piece, the superimposed thickness of the plurality of floor adjustment pads 11 with different thicknesses is greater than or equal to the width of the transverse adjustment zone 50, so that the floor adjustment pad 11 in the transverse adjustment zone 50 is tightly fitted with the adjacent floor aluminum formwork 20. Since the keel edge wing has a supporting edge for transmitting the force of the floor aluminum formwork, the floor adjustment pad 11 here can only be inserted from above the floor aluminum formwork from top to bottom, and the width and pin hole position of the floor adjustment pad 11 are consistent with the width of the floor aluminum formwork. Similarly, after the width of each point of the longitudinal adjustment zone 60 is adjusted to be consistent, the width of the longitudinal adjustment zone 60 is measured, and a plurality of floor adjustment pads 11 with different thicknesses are added into the longitudinal adjustment zone 60 piece by piece, the superimposed thickness of the plurality of floor adjustment pads 11 with different thicknesses is greater than or equal to the width of the longitudinal adjustment zone 60, so that the floor adjustment pad 11 in the longitudinal adjustment zone 60 is tightly fitted with the adjacent floor aluminum formwork 20. Since the longitudinal adjustment pad is relatively long, it can be combined with two short combined pads, the lengths of the two combined pads are the same, and the combined length and pin hole are consistent with the width of the floor aluminum formwork. In order to facilitate the installation and removal of the two combined pads, a bevel can be arranged at the junction of the two combined pads, and one or two protruding rings can be arranged at the lower edge of the combined pad to connect with the other combined pad, which facilitates the removal of the pad before the ceiling formwork is removed, and avoids the pad from being damaged.

[0055] The adjustment of the transverse adjustment zone 50 and the longitudinal adjustment zone 60 eliminates the size head phenomenon of the floor, that is, the ceiling, and the perpendicularity of the wall surface is adjusted to achieve the purpose of adjusting the transverse adjustment zone 50 and the longitudinal adjustment zone 60, and the quality of the perpendicularity of the wall surface is also considered.

[0056] It should be noted that when the floor adjustment pad 11 is added to the transverse adjustment zone 50 and the longitudinal adjustment zone 60, a wedge-shaped adjustment pad is first used to expand a certain space at the transverse adjustment zone 50 and the longitudinal adjustment zone 60, and then the floor adjustment pad 11 is added, and after the installation of the floor adjustment pad 11 is completed, the wedge-shaped adjustment pad is removed and tightened.

[0057] Further, when there are multiple rooms at the construction site, the above steps S4 and S5 are used to sequentially adjust and lock the floor aluminum formwork 20 of each room, and finally the beam aluminum formwork 40 and the wall surface aluminum formwork 30 are locked, and the construction of the aluminum formwork is completed.

[0058] It should be noted that, as shown in Figure 3 In this embodiment, the transverse adjustment strip 50 is located on one side of the keel 70, and the floor aluminum formwork 20 on one side of the keel 70 is the same formwork, so the transverse adjustment strip 50 can be considered as a complete adjustment strip longitudinally passing through the floor aluminum formwork 20. When the longitudinal adjustment strip 60 passes transversely through the floor aluminum formwork 20, due to the different specifications of the aluminum formwork arranged transversely, the longitudinal adjustment strip 60 is discontinuous, and is interrupted when encountering aluminum formwork of different specifications during transverse arrangement, and is then extended from the edge of the aluminum formwork. In this embodiment, the longitudinal adjustment strip 60 is divided into six parts, as shown in Figure 3 from left to right, they are the first longitudinal adjustment strip 61, the second longitudinal adjustment strip 62, the third longitudinal adjustment strip 63, the fourth longitudinal adjustment strip 64, the fifth longitudinal adjustment strip 65, and the sixth longitudinal adjustment strip 66.

[0059] In this embodiment, when the beam adjustment pad and the L-shaped corner connecting plate are installed, the width shape and pin hole position of the beam adjustment pad and the L-shaped corner connecting plate are consistent with the adjacent side wing.

[0060] In this embodiment, when the wall adjustment pad is installed, the back of the wall body needs to be locked before the beam plate is installed, and the wall body pad needs to be installed without loosening the back. According to the actual situation, three kinds of pads can be set: (1) In the range covered by the back, set the wall surface adjustment pad with a length slightly wider than the back, and set the circular ring at the outer edge for easy installation and connection with the edge of the wall surface adjustment pad; (2) Set a longer wall surface adjustment pad between the two backs, with an appropriate length, and cooperate with the short wall surface adjustment pad below the back; (3) After the ceiling surface and the wall body perpendicularity adjustment is completed, the adjustment strip of the wall body plate may be large at one end and small at the other end. In order to adapt to this situation, a long wall surface adjustment pad with large and small edges is set between the two backs, the length of the wall surface adjustment pad is slightly smaller than the normal pad, and the pin hole needs to be slightly widened and lengthened, so that the wall surface adjustment pad can play the role of a wedge. When the wall body plate is installed, in order to ensure that the large and small head pads do not loosen, the pins at intervals are replaced by screw rods and nuts for fastening.

[0061] Since the transverse adjustment strip or the longitudinal adjustment strip may not be a continuous straight line or may not be in the same plane, when the width of the adjustment strip changes, a part of the formwork on both sides of the joint may move out of position. This area is called a misalignment connection area. The pin holes in the misalignment connection area are horizontally widened by 10 mm to ensure that when the adjustment strip moves within a certain range, the pin holes of the aluminum formwork on both sides of the misalignment connection area can be inserted into the pin to be locked.

[0062] At the same time, the wings and the gaskets are added to reinforce the area and avoid deformation caused by the excessively large hole. Since the width of the adjusting belt is adjustable, the length of the pin needs to be lengthened by 15-20 mm, and the original gasket of the pin needs to be matched.

[0063] In the embodiment of the present application, the adjusting gasket assembly 10 is added on the basis of the existing aluminum formwork. The structure becomes a controllable subsystem in the aluminum formwork building process. The addition of the subsystem makes the stress of the entire building process smaller and controllable, greatly reduces the deformation degree of the aluminum formwork, and improves the service life of the aluminum formwork. Moreover, due to the structure and building method, the aluminum formwork building does not need to follow the progress of the workers in time. It only needs to be strictly controlled at the key points of the adjusting belt. When the inspection is unqualified, the cost of rectification is small, the treatment is simple, the construction progress is improved, the cost is saved, and the construction progress is improved.

[0064] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
