Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a high-efficiency construction method for exterior wall decorative strips. Background Art

[0002] Currently, designers often use lightweight materials such as slats to achieve decorative exterior wall effects during construction. These lightweight slats are often secured to the main structure using post-installed fasteners. Common installation methods include hook bolts, sliding bolts, and internal anchors (see Autoclaved Aerated Concrete Blocks and Panel Construction 13J104 and other relevant standards for details). These installation methods involve installing the lightweight slats after the main structure is completed, and the construction of the lightweight slats is not synchronized with the main structure. Due to this asynchronous construction, common installation methods are prone to the following problems:

[0003] 1) Since the decorative structure of the exterior wall of a building is usually constructed after the main structure is completed, the structural frame has been removed. The decorative structure needs to be constructed using an external hanging basket. The operation method of the external hanging basket has a low safety factor and often becomes a major hidden danger to construction safety. Even if the structural frame is not removed, due to the obstruction of the cantilever plate, when constructing the decorative structure, the materials need to be transported from the room through the window to the external frame outside the exterior wall. Large construction machinery such as tower cranes cannot be used, making transportation extremely inconvenient. In addition, the small amount of work but the long service life of the external frame will increase the construction cost.

[0004] 2) The decorative structure will be constructed after the main structure is completed. The facade decoration construction can only be carried out after the decorative structure is completed, which will extend the total construction period;

[0005] 3) Since the existing installation method is to install the decorative strips after the construction of the upper and lower cantilever panels is completed, the decorative strips can only be placed in place by horizontal plugging. As a result, the bonding mortar between the decorative strips and the upper cantilever panels can only be constructed by the post-plugging method. However, it is difficult to ensure the density of the bonding mortar constructed by the post-plugging method. Moreover, since the shrinkage of the post-plugging mortar is greater than that of the completed cantilever panels, cracks are easily formed at the post-plugging mortar. Summary of the Invention

[0006] The present invention aims to provide an efficient construction method for exterior wall decorative strips to solve the technical problems.

Figure 1-10 , the preferred embodiments of the present invention are further described in detail:

[0044] like Figure 1-10As shown, a preferred method of efficiently constructing exterior wall decorative strips of the present invention comprises the following steps:

[0045] Step S1: Set the lowest floor where the decorative strips 4 are arranged as the base floor, and first construct the main structure of each floor below the base floor;

[0046] Step S2, construct the base layer structural floor 1 and cantilevered plate 2, carry out the steel bar binding, formwork support and concrete pouring process of the structural floor 1 and cantilevered plate 2, and pre-embed the connecting plate 5 for fixing the base layer decorative strip plate 4 at the designed position of the cantilevered plate 2, as shown in FIG. Figure 1-2 As shown, the connection plate 5 is arranged in the following two forms. The first form is as follows: Figure 1 As shown, the connecting plate 5 is arranged vertically, with its middle section buried in the cantilever plate 2, and its two ends extending out of the cantilever plate 2 and respectively attached to the surface of the decorative strip plate 4 arranged above and below the cantilever plate 2; the second type is as shown in FIG. Figure 2 As shown, the connecting plate 5 is vertically arranged, with one end embedded in the cantilever plate 2 and the other end extending out of the cantilever plate 2 and attached to the surface of the decorative strip 4 above or below the cantilever plate 2. The connecting plate 5 of the first structural form can improve the integrity between the decorative strip 4 and the main structure. In order to ensure the connection stability of the decorative strip 4, the connecting plate 5 is embedded in the cantilever plate 2 and is provided with a plurality of anti-pullout holes 8 at intervals on the plate body, and the top or bottom end of each decorative strip 4 is fixedly connected to the cantilever plate 2 by at least two connecting plates 5.

[0047] Step S3, constructing the reference layer structural wall 3, performing the structural wall 3 positioning and setting out, steel bar binding, formwork support and concrete pouring processes;

[0048] Step S4, construct the base layer decorative strip 4, carry out the process of positioning and installing the decorative strip 4, after installation, temporarily fix the installed decorative strip 4 by temporary fixing measures, the specific installation process of the decorative strip 4 is as follows,

[0049] Step S41: After the aerated concrete decorative strips 4 and the supporting accessories are inspected and accepted, they are cut and assembled according to the construction drawings and detailed plans. The assembled components need to be cured for 7 days before they can be hoisted.

[0050] Step S42, countersunk holes 10 and bolt holes for inserting connecting screws 7 are opened on the top and bottom of the decorative strip 4. In order to ensure the molding appearance of the decorative strip 4, the connecting nut 6 is welded and fixed to the connecting plate 5, and the end of the connecting screw 7 away from the screw head passes through the decorative strip 4 and is screwed and fixed on the connecting nut 6. Countersunk holes 10 are opened on the decorative strip 4 at the setting position of the screw head of the connecting screw 7, the setting position of the connecting nut 6 and the setting position of the connecting plate 5. The screw head of the connecting screw 7, the connecting nut 6 and the connecting plate 5 are all located in the countersunk holes 10, and the outer facade of the connecting plate 5 is flush with the plate surface of the decorative strip 4. At the same time, in order to ensure the tightness of the connecting screw 7 and the decorative strip 4, an adjusting gasket 9 is sleeved on the rod body on the inner side of the screw head of the connecting screw 7, and the number of adjusting gaskets 9 can be increased or decreased according to actual needs;

[0051] Step S43: insert the connecting screw 7 into the bolt hole at the top of the decorative strip 4 and fix the connecting plate 5 to the decorative strip 4 through the connecting nut 6 and the connecting screw 7;

[0052] Step S44: Install an anti-lateral shift riding card 12 at an appropriate position on the control line of the structural wall 3, clean the end surface of the decorative strip 4 to be spliced, and pre-pave a 5-8 mm thick pre-mixed special polymer bonding mortar 11. Clean the splicing surfaces between the cantilever board 2 and the decorative strip 4, and between the structural wall 3 and the decorative strip 4, and apply a 5-10 mm thick special polymer bonding mortar 11 on the splicing surfaces. Before applying the mortar, sprinkle an appropriate amount of water on the decorative strip 4, the cantilever board 2, and the structural wall 3 to moisten them.

[0053] Step S45, adjusting the pre-buried connection plate 5 in the main concrete structure according to the control line to ensure its correct position;

[0054] Step S46, after the decorative strip 4 is hoisted and moved to the installation position, it is gently positioned according to the control line, and after vertical adjustment, the bottom countersunk hole 10 of the decorative strip 4 and the bolt hole are aligned with the pre-buried connecting plate 5 on the reference layer structure floor 1, and the upper end of the decorative strip 4 is temporarily fixed by temporary fixing measures, such as Figure 3 As shown, the temporary fixing measures include anchor bolts 14, L-shaped plate clips 15, tie bolts 16 and anchor plate clips 17. The horizontal plate of the L-shaped plate clip 15 is attached to the top surface of the decorative strip board 4, and its vertical plate is set on the side close to the structural wall 3. The horizontal plate of the L-shaped plate clip 15 is fixed to the decorative strip board 4 by the anchor bolts 14, and the decorative strip board 4 is provided with mounting holes 13 for screwing the anchor bolts 14. The vertical plate of the L-shaped plate clip 15 is connected to the anchor plate clip 17 embedded in the structural wall 3 by tie bolts 16 arranged horizontally through the gaps between the longitudinal reinforcement 18 of the wall of the swinging section. The plate body of the anchor plate clip 17 embedded in the structural wall is provided with several anti-pullout holes 8 to ensure that its plate body can be effectively consolidated in the concrete of the structural wall 3.

[0055] Step S47: Secure the decorative strip 4 to the pre-embedded connecting plate 5 of the base layer cantilever plate 2 using the connecting nut 6 and the connecting screw 7 to secure the lower end fixing point of the decorative strip 4. When installing multiple decorative strips 4 arranged along the depth direction, the decorative strips 4 close to the concrete structural wall 3 should be installed first to facilitate fixing.

[0056] Step S48: After the decorative strips 4 are installed and fixed, the excess bonding mortar 11 at the joints should be cleaned. After the upper cantilever slab 2 is concreted and the bonding mortar 11 at the joints has increased in strength, a mesh cloth reinforcement strip is bonded to the joints to strengthen the joints.

[0057] Step S5, construct the first layer of structural floor 1 and cantilever slab 2 above the reference layer, carry out the steel bar binding, formwork support and concrete pouring processes of the structural floor 1 and cantilever slab 2, pour the top connecting plate 5 of the decorative strip 4 of the reference layer into the cantilever slab 2 and pre-embed the connecting plate 5 for fixing the first layer of decorative strip 4 above the reference layer at the designed position of the cantilever slab 2. In order to strengthen the integrity of the structural system, the connecting plate 5 can be a whole piece that passes through the cantilever slab 2 (such as Figure 1 As shown), that is, the connecting plate 5 is arranged vertically, with its middle section buried in the cantilever plate 2, and its two ends both extend out of the cantilever plate 2 and are respectively attached to the board surface of the decorative strips 4 arranged above and below the cantilever plate 2, and both ends of the connecting plate 5 are fixed to the decorative strips 4 at the corresponding positions by matching connecting nuts 6 and connecting screws 7. When supporting the formwork of the cantilever plate 2, it is necessary to pay attention that since some decorative shapes are closed spaces surrounded by decorative strips 4, at this time, the formwork of the upper concrete cantilever plate 2 cannot be removed after the concrete is poured, so the wooden formwork here can be replaced with a 20mm thick reinforced cement pressure plate, which will not be removed after the concrete of the cantilever plate 2 is poured;

[0058] Step S6: construct the first layer of structural wall 3 above the reference layer, and perform the steps of positioning and setting out the structural wall 3, tying steel bars, setting up formwork, and pouring concrete;

[0059] Step S7, constructing the first layer of decorative strips 4 above the reference layer, performing a positioning and laying-out process for the decorative strips 4, opening bolt holes for installing the connecting screws 7 at the top and bottom of the decorative strips 4, inserting the connecting screws 7 into the bolt holes at the top of the decorative strips 4, and fixing the connecting plates 5 to the decorative strips 4 by means of the connecting nuts 6 and the connecting screws 7, hoisting the decorative strips 4 into place according to the control lines, aligning the bottom countersunk holes 10 of the decorative strips 4 with the bolt holes with the pre-embedded connecting plates 5 of the reference layer structural floor 1, temporarily fixing the installed decorative strips 4 by means of temporary fixing measures, and then fixing the decorative strips 4 to the pre-embedded connecting plates 5 of the reference layer cantilever slab 2 by means of the connecting nuts 6 and the connecting screws 7;

[0060] Step S8: Construct the second-layer structural floor slab 1 and cantilever slab 2 above the reference layer. Rebar binding, formwork support, and concrete pouring are performed for the structural floor slab 1 and cantilever slab 2. The top connecting plate 5 of the first-layer decorative strips 4 above the reference layer is poured into the cantilever slab 2. The connecting plate 5 for securing the second-layer decorative strips 4 above the reference layer is pre-embedded at the designed position of the cantilever slab 2.

[0061] Step S9: reset the reference layer to the first floor below the current construction floor, and repeat the corresponding operations of steps S6 to S8 to perform subsequent floor construction until the structure is topped out.

[0062] By optimizing the connection nodes of the decorative strips 4 and changing the construction process, the decorative strips 4 and the main structure are constructed synchronously, thereby making the present invention have the following advantages:

[0063] 1) The decorative strips 4 are constructed simultaneously with the main structure, which can effectively utilize the structural frame for protection and improve the safety of construction;

[0064] 2) The simultaneous construction of the decorative strips 4 and the main structure is a normal construction sequence, avoiding obstruction by the top cantilever plate 2. The decorative strips 4 can be lifted and installed vertically, and large equipment such as tower cranes can be effectively used to lift construction materials, thereby improving construction efficiency;

[0065] 3) The construction period can be shortened. After the main structure is completed, the decorative structure of the facade is also completed. After the external frame is removed, the insulation and decoration construction of the facade can be carried out;

[0066] 4) The decorative strips 4 are constructed simultaneously with the main structure. The lower part of the decorative strips 4 is directly pressed on the bonding mortar 11, and the upper part of the decorative strips 4 is directly poured together with the concrete of the cantilever slab 2 as a formwork. The upper and lower contact surfaces of the decorative strips 4 are very dense. Moreover, since they are constructed simultaneously with the concrete of the main structure, the shrinkage difference is very small, it is not easy to crack, and the integrity is better.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
