Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a method for constructing multidimensional, multi-curved thin-walled cavity inclined surface fair-faced concrete. Background Technology

[0002] In large buildings such as art centers and stadiums, in order to achieve both aesthetic appeal and overall structural stability, the exterior shape is often formed by casting concrete in a single pour using irregular surfaces. This significantly increases the difficulty of casting at the corners of the arches and steps, due to the irregular shapes and the need to achieve thin walls and cavities in the building structure. Currently, casting is generally done using wooden molds to form casting troughs. However, due to spatial constraints at the corners of the arches and steps, simple wooden mold casting can lead to deformation and displacement of the molds during casting, resulting in construction quality issues. Therefore, we have designed this concrete casting construction method.

[0003] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Summary of the Invention

Detailed Implementation

[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] Please see Figure 1-12 This invention provides a technical solution: a method for constructing multidimensional, multi-curved thin-walled hollow inclined surface fair-faced concrete, wherein it should be noted that, referring to Figure 2 and Figure 3 The irregularly shaped components to be cast are multi-dimensional, curved components. At the same time, during the casting process, a sloping cavity structure will be formed at the handrail position of the step balustrade 3. The construction steps include the following:

[0058] S1. Concrete pouring of the shaped arch 1. The shaped arch 1 is composed of multiple column bases. When pouring the column bases, the column bases are poured and shaped in the corresponding positions according to the design drawings. Then, the position and angle of the column bases are adjusted to connect them into a semi-circular shape. The staircase is poured at the gap in the semi-circular shape formed by the column bases.

[0059] S2. Installation of the balustrade template 2, wherein the balustrade template 2 includes a flanged balustrade 4, a stepped balustrade 3, and a corner template at the connection between the stepped balustrade 3 and the flanged balustrade 4.

[0060] The installation of the parapet template 2 in step S2 includes:

[0061] S21. First, install the corner template at the connection between the step railing 3 and the flange railing 4 at the column pier of the staircase. Then, pour concrete inside the template. The corner template is made of steel mold 5.

[0062] S22. After the corner template is installed and poured, the template is installed and poured on both sides of the flange panel 4 and the step panel 3, using this as the base point.

[0063] S3, Step balustrade 3 and upper flange balustrade 4 of shaped arch 1 are installed and poured;

[0064] S31. Before the installation and pouring of the step balustrade 3, the outer formwork 61 of the handrail of the step balustrade 3 is installed first, followed by the installation of the extruded polystyrene board 7 on the inner side of the handrail of the step balustrade 3, the installation of the inner formwork 62 on the outer side of the handrail of the step balustrade 3, and finally the installation of the step balustrade 3 is reinforced and supported. After the reinforcement and support are reinforced, the pouring operation is carried out. The inclined surface of the outer formwork 61 is a wooden mold 6, and the pouring formwork of the step balustrade above the shaped arch 1 is a steel mold 5.

[0065] S32. First, install the outer formwork of the flange panel 4, and reinforce it after installation. After the reinforcement is completed, carry out the concrete pouring operation inside the formwork.

[0066] In S2, the reinforcement support of the parapet template 2 adopts a template support system 8, which includes:

[0067] Support frame 81 is erected on the ground and located on both sides of the step handrail;

[0068] Multiple steel mold support units 82 are disposed between the support frame 81 and the steel mold 5 to support the steel mold 5;

[0069] Multiple wooden mold support units are arranged between the support frame 81 and the wooden mold 6 to support the wooden mold 6.

[0070] In addition, the steel formwork support unit 82 includes:

[0071] A fixing collar 821 is sleeved on the support frame 81, and a first threaded rod 822 is ball-hinged on the fixing collar 821;

[0072] A threaded sleeve 823 is threadedly connected to a first threaded rod 822, and a second threaded rod 824 is threadedly connected to the end of the threaded sleeve 823 away from the first threaded rod 822.

[0073] The abutment block 825 is ball-hinged to the end of the second threaded rod 824 away from the threaded sleeve 823;

[0074] In actual support, the fixing collar 821 can be sleeved on the support frame 81, and then the length between the first threaded rod 822 and the second threaded rod 824 can be adjusted by rotating the threaded sleeve 823, so that the abutment block 825 is inserted into the groove of the steel mold 5. The first threaded rod 822 and the second threaded rod 824, the fixing collar 821 and the abutment block 825 are ball-jointed, so that the steel mold support unit 82 can adapt to support different parts of the irregular steel mold 5. It is best to fix the fixing collar 821 on the support frame 81 after the support is in place.

[0075] The wooden mold support unit uses the same components. When supporting the wooden mold 6, the abutment block 825 can be replaced with a clamping plate, so that the end of the wooden mold support unit and the end of the wooden mold 6 can be connected. In order to better achieve this connection, multiple strips are fixed on the outer wall of the wooden mold 6 and evenly arranged to cooperate with the clamping plate to achieve clamping. The length of the threaded rod is adjusted to effectively support the irregular wooden mold 6.

[0076] Meanwhile, in S3, the extruded polystyrene board 7 inside the steel mold 5 and the wooden mold 6 is installed using a reinforcing fixture 9 for installing the extruded polystyrene board 7. The reinforcing fixture 9 for the extruded polystyrene board 7 includes:

[0077] Multiple pressing plates 91 are rotatably mounted on the wooden mold 6 via a rotating shaft 92, and the shape of the pressing plates 91 is adaptively set according to the upper surface of the casting groove formed by the wooden mold 6.

[0078] Among them, the appendix Figure 3 , 4 The diagram in the middle shows the number of extruded polystyrene (XPS) boards when there are 3 sets, but the actual number is not 3 sets. This diagram is used to simplify the understanding of the connection principle at the pressing plate.

[0079] The pressing component 93 is disposed on the pressing plate 91 and is used to press and fix the upper surface of the poured concrete during concrete pouring.

[0080] The reinforcing component 94 is mounted on the pressing plate 91 and is used to reinforce the extruded polystyrene board 7 during concrete pouring.

[0081] The rotating shaft 92 for rotating the pressing plate 91 is located at the lower end of the pressing plate 91. Thus, when the pressing plate 91 is installed on the wooden mold 6, the pressing plate 91 will be in a vertical position due to gravity. As concrete is poured, the concrete in the pouring groove formed by the wooden mold 6 rises, and the pressing plate 91 rotates accordingly until it covers the upper surface of the wooden mold 6, thereby achieving a cover on the upper surface of the pouring groove. Since the upper surface of the wooden mold 6 is inclined upwards, in actual pouring, the pouring is carried out in segments according to the number of pressing plates 91. The pressing assembly 93 includes:

[0082] The limiting plate 95 is fixedly set on the wooden mold 6 to limit the rotation angle of the pressing plate 91, so that the pressing plate 91 of this section can remain flush with the wooden mold 6 of this section after being limited. Under the action of the concrete itself, that is, the wooden pressing plate 91 has a certain buoyancy on it, and due to the inclination of the wooden mold 6, the pressure from top to bottom is not consistent, so the pressure on the lower end of the pressing plate 91 is greater than the pressure on the upper end. Thus, after the concrete is poured, the pressing plate 91 will be fixed in place with the action of the limiting plate 95. That is, after the concrete is poured, the pressing plate 91 will be at the limiting angle of the limiting plate 95.

[0083] The bonding plate 96 is fixedly installed on the lower surface end of the two adjacent pressing plates 91 located at the upper end of the pressing plate 91. The other pressing plate 91 adjacent to it is provided with a bonding groove 97 for bonding. The bonding plate 96 and the bonding groove 97 can make the two adjacent pressing plates 91 fit tightly when pressed, so as to prevent concrete from leaking from there. Since the upper surface of the wooden mold 6 is inclined, due to the height difference, concrete is prone to leak from the connection between the two pressing plates 91 below. This problem is solved to make the connection tighter.

[0084] Two scraping parts 98 are located at adjacent positions of the two pressing plates 91, and are used to remove concrete residue adhering to the upper end of the bonding plate 96 and the surface of the bonding groove 97 during the rotation and covering process of the pressing plates 91.

[0085] The shovel section 98 includes:

[0086] Two spade plates 981 are slidably disposed at the upper end of the bonding plate 96 and the upper end of the bonding groove 97 of the two pressing plates 91, respectively.

[0087] The power unit 982 is located between the shovel plate 981 and the wooden mold 6, and is used to drive the shovel plate 981 to perform one extension and retraction slide when the pressing plate 91 rotates to the limit plate 95 angle.

[0088] The power unit 982 includes:

[0089] Two guide plates 9821 are provided on both sides of the wooden mold 6, and the guide plates 9821 are provided with folded grooves 9822;

[0090] The connecting plate 9823 is fixedly installed at one end with the shovel plate 981, and the other end passes through the pressing plate 91 to the upper end of the pressing plate 91 to the guide roller 9828. The two ends of the guide roller 9828 are slidably installed in the folded sliding groove 9822 of the guide plate 9821. The pressing plate 91 is provided with a sliding groove 9824 for the sliding of the connecting plate 9823.

[0091] When concrete is poured, the guide roller 9828 will slide in the folded groove 9822 as the pressing plate 91 rotates. This will cause the shovel plate 981 to slide through the connecting plate 9823, achieving a single extension and retraction slide. This will clean the concrete that adhered to the position during concrete pouring, allowing the two adjacent pressing plates 91 to fit more tightly together.

[0092] In addition, the wooden mold 6 is provided with rotating half grooves 9825 on both sides for supporting the rotating shaft 92, and the two ends of the rotating shaft 92 are provided with fixing mechanisms for limiting the upper and lower positions of the rotating shaft 92 at the wooden mold 6.

[0093] The fixing mechanism includes:

[0094] A fixed block 9826 is slidably mounted on the wooden mold 6. The fixed block 9826 is provided with a circular groove for limiting the other side of the rotating shaft 92. The wooden mold 6 is provided with a limiting groove for the fixed block 9826 to slide.

[0095] A fixed spring 9827 is set in the limiting slide groove to increase the pressing force of the fixed block 9826;

[0096] The fixing block 9826 can be pulled to both sides of the limiting slide groove. Then, the rotating shaft 92 of the pressing plate 91 is placed on the rotating half groove 9825. After releasing the fixing block 9826, the fixing block 9826 will move under the action of the fixing spring 9827, thereby limiting the upper half of the rotating shaft 92 and thus fixing it. After the concrete is fixed, the fixing block 9826 can be removed and the pressing plate 91 can be taken off.

[0097] Finally, the reinforcement component 94 includes: an elastic telescopic rod 941, one end of which is fixed to the inner arm side of the pressing plate 91, and the other end is fixed with a reinforcement plate 942 for abutting against the extruded board 7;

[0098] When the pressing plate 91 rotates to the angle of the limiting plate 95, the elastic telescopic rod 941 retracts to its minimum length and simultaneously squeezes the extruded board 7, thereby preventing the buoyancy generated after the concrete is poured from causing the extruded board 7 to float up, thus affecting the deformation of the thin-walled cavity after molding.
