Description

Technical Field

[0001] The present invention relates to the field of high-weather-resistant and high-durability building construction equipment, in particular to a joint template for a high-weather-resistant and high-durability disassembly-free formwork and a construction method. Background Art

[0002] In building construction, the assembly construction method of the formwork without disassembly can greatly improve construction efficiency. The use of UHPC (ultra-high performance concrete) in coastal buildings can greatly improve the weather resistance and durability of the building, resist the invasion of chloride ions, and extend the service life of the building. According to laboratory data, the service life of UHPC can reach 100 years, while ordinary concrete does not exceed 50 years. However, in the existing construction methods, connecting seams need to be set between the upper and lower columns, between beams and columns, between wall panels, between wall columns, and between wall beams to facilitate the connection construction of steel bars. Concrete is poured at the location of the connecting seams to form connecting seams. For example, the solutions in the Chinese patent document CN114482299A low-rise assembled composite wall panel connection structure and construction method thereof, CN120250792A prefabricated beam-column assembled connection node structure and construction method, and CN120042279A prefabricated column and transfer beam connection node and construction method thereof. However, in the UHPC formwork construction system, the location of post-poured concrete constitutes a weak point in highly weather-resistant and durable buildings, because if UHPC is post-poured at this location, the construction cost will be too high, and leakage is prone to occur at the junction of new and old concrete. The use of ordinary concrete constitutes a weak point in weather resistance and anti-seepage, and the overall weather resistance and durability requirements cannot be met. Post-poured concrete structures are prone to honeycomb, rough surface or misalignment defects, which are very different from the appearance of the non-disassembly formwork. If a solution of combining UHPC formwork with ordinary concrete is adopted, due to the inconsistent size of the connection seams, if UHPC formwork for splicing is prepared according to different sizes, the process will be cumbersome, the construction efficiency will be low, and the construction cost will be high. The content recorded in the background technology is only for the convenience of reading and understanding, and is not an admission of the prior art. Summary of the Invention

DETAILED DESCRIPTION

[0028] A building located near the sea, exposed to salt spray and a cyclical, dry-wet climate, requires improved weather and corrosion resistance, as well as improved service life. Existing formwork that requires no disassembly integrates the rebar cage with the formwork to improve construction efficiency. However, at the joints between the formwork, such as where columns on the current floor connect to pre-existing columns and where walls connect to pre-existing wall caps, the rebar cage and formwork must be connected. The current practice is to use traditional construction methods, where the main reinforcement of the rebar cage is first connected by welding or sleeves before pouring concrete outside the formwork. To facilitate construction, the joints are typically 15-20 cm wide. Compared to UHPC, the newly poured concrete has insufficient impermeability, creating leakage channels. UHPC costs 10-14 times more than ordinary concrete. This makes it difficult to fully pour UHPC at the joints, requiring only conventional C30-C50 concrete. This makes the joints vulnerable to weather and corrosion resistance, failing to meet the requirements for weather resistance, corrosion resistance, and an extended service life. The inventors have proposed an adjustable-width joint formwork, which can be prefabricated using UHPC. This design achieves weather and corrosion resistance across the entire building surface, achieving the desired technical results while reducing overall costs. It also creates a uniform and attractive overall appearance, allowing for direct coating or interior and exterior finishes. This eliminates the need for non-weather-resistant construction techniques like putty, indirectly improving the building's weather and corrosion resistance.

[0029] Example 1: like Figures 1-3 In the embodiment, a joint formwork for a highly weather-resistant and durable non-disassembly formwork comprises a first connecting plate 105 and a second connecting plate 110. A baffle 109 is provided on the back of the first connecting plate 105, and the second connecting plate 110 is in sliding contact with the first connecting plate 105. In this embodiment, the side of the joint formwork to be poured with concrete later is the back side, and the opposite side is the front side. Figure 1 and Figure 3 The left side is the back and the right side is the front. Figure 2The structure of the rotating joint template 101 is shown in the figure. The inner enclosed side is the back side, and the outer unenclosed side is the front side. Preferably, when the joint template is used as a formwork for an exterior wall, the second connecting plate 110 is located at the top. The overlapping connection structure of the second connecting plate 110 and the baffle 109 prevents water from entering the exterior wall. When the joint template is used as a formwork for an interior wall, the first connecting plate 105 is located at the top. The overlapping connection structure of the baffle 109 and the second connecting plate 110 prevents water from penetrating downward from the top of the interior wall from entering the interior. Typically, after construction is completed, an adhesive is applied to the overlapping portion of the baffle 109 and the second connecting plate 110. Preferred adhesives include the A / B two-component modified epoxy resin adhesive produced by Sino-German Xinya Building Materials Co., Ltd. or the LD-S113 A / B two-component modified epoxy resin adhesive produced by Liding Electronic Materials Co., Ltd. Tests have shown that their bonding tensile strength exceeds 25 MPa, indicating high anti-seepage performance. The small section between the ends of the vertical joint formwork 102 and the horizontal joint formwork 103 is also sealed with adhesive to improve overall impermeability and weather resistance. The formwork is typically 20mm to 25mm thick, and the adhesive coating is controlled at 1-3mm. This minimizes the amount of adhesive required and has a minimal impact on overall construction costs.

[0030] like Figures 1-3 As shown in , a plurality of screws 108 are fixedly provided at the upper end of the first connecting plate 105. For flat-type joint templates, such as vertical joint templates 102 and horizontal joint templates 103, a plurality of screws 108 are evenly distributed along the straight line direction, and for three-dimensional joint templates, such as rotary joint templates 101, the screws 108 are arranged on the straight edge and evenly distributed along the straight line direction. The advantage of the technical system of the present invention is that the formwork is prepared in the factory, and high-precision surface quality can be obtained, and the plain concrete can be used directly without decoration. Moreover, very complex shapes can be obtained to enhance the artistic value of the building, such as circular cylinders, rotary cylinders with variable cross-sections, such as Roman columns, Chinese animal-based columns, large-span arch beams, bracket arches and other structural forms, and the cost increase is not much. If large-scale production is achieved, the mold cost can be reduced, and the production cost can also be reduced by improving construction efficiency.

[0031] like Figures 1-3 As shown in FIG, a guide sleeve 106 is provided on the end surface corresponding to the second connecting plate 110. A screw 108 is slidably connected to the guide sleeve 106. A nut 107 is provided on the screw 108 for limiting the position. The position of the first connecting plate 105 is adjusted by adjusting the nut 107. When the nut 107 is raised, the position of the first connecting plate 105 rises. When the nut 107 is lowered, the position of the first connecting plate 105 falls under the action of gravity, thereby adjusting the height or width of the entire joint template 100. Preferably, a double nut structure is used to facilitate locking the nuts.

[0032] In a preferred embodiment, a step structure is formed at the position where the first connecting plate 105 and the baffle 109 are connected. A circular arc transition structure is provided on the back side where the two are connected. The second connecting plate 110 is located at the position of the step structure. The overall height of the first connecting plate 105 and the second connecting plate 110 is adjusted by the nut 107; The front surfaces of the first and second connecting plates 105 and 110 are flush. The gap between the first and second connecting plates 105 and 110 left by height adjustment can be repaired by applying film, filling with concrete, or inserting decorative panels. Since waterproofing is not necessary, this treatment is relatively easy and simple to implement.

[0033] The preferred solution is Figures 1-3 In the embodiment, snap-fit ​​joints 104 are provided at the free ends of the first and second connecting plates 105, 110. These joints are equipped with projections and grooves that engage with other components. This structure allows for the various components to be connected by snap-fit. Applying adhesive to snap-fit ​​joints 104 effectively prevents leakage at the joints and ensures accurate positioning of other components.

[0034] The preferred method is Figure 1 、 3 As shown in FIG, the occlusal joint 104 adopts a prefabricated structure and is connected to the first connecting plate 105 or the second connecting plate 110 in a pre-embedded manner.

[0035] The preferred solution is Figure 4 In the embodiment, the joint template 100 includes a rotary joint template 101, a vertical joint template 102 or a horizontal joint template 103; like Figure 2 、 3 In the example, the rotating joint template 101 is used to connect and adjust the joints between the column formwork 200, or to connect and adjust the joints between the column formwork 200 and the beam-column integrated formwork 400. In this example, the column formwork 200 uses a 25mm thick UHPC formwork with a side length of 1000mm. The single-layer column is about 6 meters high, and the span between columns reaches 10 meters. According to design requirements, the column formwork 200 can be easily prepared into rectangular columns, rounded rectangular columns, circular columns, Roman columns, or other variable-section columns at roughly the same cost. It also ensures a high appearance quality, such as no honeycomb, rough surface, or misalignment defects. Even if defects do occur, they are easy to avoid.

[0036] like Figure 4 In the example, the vertical joint template 102 is used to connect and adjust the vertical joints of the wall formwork 500. Due to the large span of the wall, joints are inevitable. Some joints are fixed, but at least one adjustable joint is reserved to compensate for installation errors. The reserved width is 100mm to 200mm.

[0037] like Figure 4 The horizontal joint template 103 is used to connect and adjust the horizontal joint of the wall formwork 500. Each wall usually retains at least one adjustable joint to compensate for installation errors and facilitate the connection of steel bars. The reserved width is 100mm~200mm.

[0038] Preferably, the material of the joint template 100 is UHPC. Of course, according to the design requirements, it is also feasible to use slightly lower-grade concrete, such as C65 or above concrete.

[0039] The adjustable joint template 100 of the present invention solves the shortcomings of the highly weather-resistant and durable UHPC formwork-free construction technology system, and achieves high weather resistance and high durability on the entire surface of the structure.

[0040] Example 2: On the basis of Example 1, Figures 5-7 A construction method using the above-mentioned joint template includes the following steps: S01. Hoist the steel cage 300 of the column and connect the steel cage 300 to the steel bars of the reserved column 1; the connection methods include threaded sleeve connection or welding connection.

[0041] S02, install the rotating joint template 101 on the top of the column form 200 of the reserved column 1, and the column form 200 and the occlusal joint 104 of the rotating joint template 101 are occlusally connected to each other; usually the height of the reserved column 1 is 300mm. The structure of the occlusal joint 104 is as follows Figure 1 、 3 As shown in , when the snap joints 104 of different components are connected to each other, a high sealing effect can be achieved. Because snap joints 104 are prefabricated and embedded, they can achieve high dimensional and positional accuracy, thereby ensuring connection accuracy. The outer surface of snap joints 104 is provided with protrusions and grooves, and the inner side of snap joints 104 is provided with extension structures to facilitate reliable connection with embedded structures such as the first connecting plate 105 and the second connecting plate 110.

[0042] S03. Hoist the column formwork 200 and interlock the interlocking joints 104 of the rotating joint formwork 101 with the interlocking joints 104 of the column formwork 200. In this example, the column formwork 200 is separated from the reinforcement cage 300 to ensure connection accuracy. This also prevents deformation of the reinforcement or formwork during transportation. Preferably, depending on design requirements, the rotating joint formwork 101 can be a full ring or a partial ring structure.

[0043] Adjust the position of the nut 107 so that the column formwork 200 is at a preset elevation; S04, pouring concrete in the column formwork 200; the poured concrete is ordinary concrete, such as C30, C40 concrete, etc.; Through the above steps, the column is seamlessly connected to the reserved column 1.

Inner support cylinders 3 and outer support cylinders 6 are also provided to support the inner struts 5 and outer struts 7, respectively, to adjust the strut angles. Alternatively, a diagonal bracing structure is also feasible, but due to the unevenness of the construction site floor, the diagonal bracing base is inaccurate, affecting construction quality.

[0045] S12, hoisting the steel cage 300 of the column, supporting the steel cage 300 with a support rod, and connecting the steel cage 300 to the steel bars of the reserved column 1; S13. Install the rotary joint template 101 on the top of the column formwork 200 of the reserved column 1.
