Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a reserved opening early dismantling system for an external wall non-dismantling external formwork and an early dismantling method thereof. Background Art

[0002] At present, prefabricated composite thermal insulation non-removal formwork is generally used for concrete cast-in-place exterior walls. It has the functions of thermal insulation and non-removal formwork, referred to as prefabricated non-removal formwork. Prefabricated non-removal formwork is an integrated system of building insulation and structure. The application of this material not only saves construction time, but also saves investment in exterior wall formwork.

[0003] During the construction of high-rise buildings, climbing frames need to be set up on the periphery of the building. The climbing frames need to fix the embedded parts of the climbing frames in the concrete structure to ensure the stability of the connection. Therefore, in traditional construction practices, after the concrete pouring and maintenance is completed, it is necessary to cut and open holes on the prefabricated non-disassembly formwork until the concrete surface of the structure is exposed for the installation of the embedded parts of the climbing frames. This method requires the reinforcement system on the prefabricated non-disassembly formwork to be removed before opening holes. While the construction efficiency is low, the prefabricated non-disassembly formwork has no secondary utilization value after being cut, which affects the construction cost. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a reserved opening early dismantling system and an early dismantling method for an exterior wall non-dismantling external formwork. When it is necessary to install the embedded parts of the climbing frame, it is convenient to quickly remove the blocking parts in the reserved opening and expose the concrete surface, avoiding cutting of the non-dismantling external formwork and affecting subsequent turnover use.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is a reserved opening early dismantling system for the external wall non-dismantling external formwork, wherein the inner and outer surfaces of the external wall to be cast are respectively provided with a non-dismantling inner formwork and a non-dismantling outer formwork, and a reserved opening for the installation of a climbing frame fastener is provided through the non-dismantling outer formwork in the thickness direction, and the early dismantling system comprises:

[0006] A plugging member used to be embedded in the reserved opening, the plugging member comprising:

[0007] A bottom plate used for being embedded in the bottom of the hole of the reserved opening, wherein the bottom plate is adapted to the reserved opening;

[0008] A side panel is arranged along the inner wall of the reserved opening, the side panel is connected to the bottom panel, and the height of the side panel is equal to the depth of the reserved opening;

[0009] A plurality of limit baffles are arranged at intervals around the reserved opening, one end of each limit baffle is connected to the side plate, and the other end is placed on the surface of the non-disassembly outer template;

[0010] A back rib assembly for limiting the blocking member, the back rib assembly comprising a first back rib for blocking the surface of the non-disassembly outer formwork and spanning the reserved opening, and a second back rib for blocking the surface of the non-disassembly inner formwork and arranged corresponding to the first back rib, the first back rib and the second back rib being connected by a tension bolt group.

[0011] A further improvement of the reserved opening early dismantling system for the external wall non-dismantling external formwork of the present invention is that the blocking piece is spliced ​​by a plurality of blocking units, each of which comprises:

[0012] A bottom plate unit, when a plurality of the blocking units are spliced ​​together, the plurality of the bottom plate units are spliced ​​together to form the bottom plate;

[0013] A plurality of side panel units are provided, wherein the plurality of side panel units are located on the top of the bottom panel unit and are surrounded by the outer periphery of the bottom panel unit, and the height of the side panel unit is equal to the depth of the reserved opening. When the plurality of blocking units are spliced, the adjacent side panel units of the adjacent blocking units are abutted against each other and are detachably connected through connecting pieces, and the plurality of side panel units abutting against the inner wall of the reserved opening are spliced ​​to form the side panel.

[0014] A further improvement of the reserved opening early dismantling system for the external wall non-dismantling external formwork of the present invention is that the connecting member is a limit pin, and adjacent side plate units of adjacent blocking units are provided with insertion holes for the limit pins to be inserted.

[0015] A further improvement of the reserved opening early dismantling system for the external wall non-dismantling external formwork of the present invention is that the tension bolt group includes two first tension bolts, and the two first tension bolts are respectively arranged on opposite sides of the reserved opening and are respectively tensioned between the two ends of the first back rib and the second back rib.

[0016] A further improvement of the reserved opening early dismantling system for the external wall non-dismantling external formwork of the present invention is that the first back rib comprises two detachable butt-jointed back rib units, one end of the two back rib units away from the butt end extends to the opposite sides of the reserved opening and is respectively connected by two of the first tension bolts, and the two back rib units can rotate around the corresponding first tension bolts when in a non-joint state.

[0017] A further improvement of the reserved opening early dismantling system for the external wall non-dismantling external formwork of the present invention is that there are multiple back rib components, and the multiple back rib components are arranged at intervals within the range of the reserved opening.

[0018] A method for early removal of a reserved opening for an external wall formwork without removal, comprising the steps of:

[0019] Step 1: Providing the above-mentioned reserved opening early dismantling system for the external wall formwork to carry out formwork pouring of the external wall;

[0020] Step 2: After the exterior wall maintenance is completed, remove the first back rib;

[0021] Step 3: Remove the blocking parts as a whole and expose the surface of the outer wall for the installation of the embedded climbing frame parts.

[0022] The present invention further improves the method for early dismantling of the reserved opening of the external wall non-dismantling external formwork in that the first back rib comprises two detachable butted back rib units, one end of the two back rib units away from the butt end extends to opposite sides of the reserved opening and is connected by two first tension bolts respectively, and the two back rib units can rotate around the corresponding first tension bolts when not butted;

[0023] When executing the above step 2, the connection between the butt ends of the two back-rib units is released, and the two back-rib units are respectively rotated around the corresponding first tension bolts until the two back-rib units are no longer blocked by the reserved opening.

[0024] Compared with the prior art, the advantages of the present invention are:

[0025] 1. By setting reserved openings and matching blocking parts, the blocking effect of the non-dismantling external formwork is guaranteed during concrete pouring. At the same time, during the subsequent installation of embedded parts of the climbing frame, the blocking parts can be directly removed without cutting the non-dismantling external formwork, which facilitates the turnover of the non-dismantling external formwork and saves costs.

[0026] 2. By configuring the blocking member to be a plurality of blocking units, the use of blocking units can be increased or decreased according to the size of the reserved opening to adapt to the size of the reserved opening, thereby improving practicality. BRIEF DESCRIPTION OF THE DRAWINGS
