DETAILED DESCRIPTION

[0041] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0042] Example 1. This embodiment aims to provide a cast-in-place wall component for house construction, which is mainly used for cast-in-place construction of walls in house construction. Existing cast-in-place walls are generally cast with concrete walls based on external molds. This structure requires repeated demolding, is more troublesome to use, and the overall structure is prone to cracks and poor surface flatness due to uneven settlement. This embodiment provides a cast-in-place wall component for house construction that uses concrete slabs as templates for casting.

[0043] In terms of structure, this embodiment Figure 1-5 It is shown in the figure that a cast-in-place wall component for house construction includes side panels 1, connecting panels 2, transverse clamping members, transverse reinforcement and vertical reinforcement 15. Structurally, the side panels 1 are on both sides, and the connecting panels 2 are in the middle. The side panels are connected transversely to form a U-shaped inner cavity. Structurally, the side panels 1 are arranged horizontally, and the connecting panels 2 are arranged transversely, and multiple connecting panels are arranged at intervals. In this embodiment, the wall panel structure has two side panels 1 and multiple connecting panels 2 connecting the two side panels. The side panels 1 can be blocked from both sides, and the connecting panels 2 can connect the side panels, thereby avoiding additional tension and fixation of the side panels. At the same time, the connecting panels 2 divide the space between the side panels into multiple areas to facilitate sufficient contact and fixation with the concrete. At the same time, the present invention uses the concrete slab as a template in the structure. The structure does not need to be demolded and can be used as part of the wall.

[0044] The upper, lower, front, and rear sides of the side panel 1 are provided with corresponding butt joints and butt grooves. As shown in Figure 1, the butt joint 3 and butt groove 4 are adapted to be connected to each other, and the butt joint 3 has multiple sealing steps. This connection creates a multi-layer sealing structure, ensuring the sealing of the structural connection.

[0045] In this embodiment, grooves are provided on the upper and lower parts of each connecting plate 2; the transverse reinforcement is arranged in the upper groove 5 and the lower groove 6, and the upper and lower transverse reinforcements are fixed together with the vertical reinforcement by connecting pieces wrapped around the vertical reinforcement 15; in the specific example structure, the upper groove 5 and the lower groove 6 are arranged correspondingly along the vertical direction, and the transverse reinforcement is arranged on the same side, and the connecting piece 16 includes a bending portion, an upper hook portion and a lower hook portion, and the bending portion bypasses the vertical reinforcement, and the upper hook portion and the lower hook portion are at the end of the bending portion, and respectively correspond to corresponding upper hanging grooves and lower hanging grooves, and the upper groove and the lower groove are provided on the connecting plate, which can accommodate the clamping and limiting transverse reinforcement and establish a fixed relationship between the transverse reinforcement and the vertical reinforcement. As shown in Figure 4, the upper transverse reinforcement 13 and the lower transverse reinforcement 14 are limited on the connecting plate and connected to the wall, and the structural stability is good.

[0046] The horizontal clamping member includes a limit groove 8, a limit block 9, a first connecting rod 10, a connecting sleeve 12 and a second connecting rod 11. A limit groove 8 is provided on two adjacent assembled connecting plates. The limit groove 8 has a trapezoidal inner cavity. The bottom of the limit groove is hollowed out or has a transparent structure. The inner cavity structure has two inwardly inclined compression slopes. An avoidance groove is provided on the upper side of the inner cavity. The avoidance groove is used to pass the first connecting rod 10 and the second connecting rod 11. Structurally, the first connecting rod 10 and the second connecting rod 11 are reverse-threaded screws. The two connecting rods are threadedly connected by a connecting sleeve adapted thereto. The limit block 9 is fixed to the connecting rod. At the outer end, the limit block 9 is smaller than the limit groove 8 and can be adapted to fit tightly against the inner wall of the inclined surface of the limit groove 8. By utilizing the trapezoidal limit groove structure, the limit block 9 is placed in the limit groove 8 on the corresponding side by adjusting the distance between the limit blocks 9 at both ends. At this time, the adapted inclined surface of the limit block 9 does not contact the inclined surface of the limit groove 8. By rotating the connecting sleeve, the first connecting rod 10 and the second connecting rod 11 can be retracted inward, thereby making the limit block 9 lean against the limit groove 8 and applying a locking force to both sides to the limit groove, ensuring that the butt joint of the side panel can fit tightly with its corresponding butt joint groove, avoiding leakage of slurry here, and having good structural integrity.

[0047] In the specific implementation structure, the limit groove 8 is an isosceles trapezoidal structure, and the limit block 9 is adapted to the limit groove 8. The isosceles trapezoidal structure can ensure that the force is centered, and the force of the connecting rod can be evenly adapted and supported by the two sides of the isosceles trapezoid, so the force is evenly distributed.

[0048] In this embodiment, the side panels 1, connecting panels 2 and limiting grooves 8 are integral concrete castings, and a connecting hole 7 is provided on the connecting panel 2. In this embodiment, the wall structure is an integral concrete casting, the outer surface of the structure is pre-formed and has good flatness, and is assembled after being transported to the site. The transverse structures are tensioned and locked by transverse clamping members, and have good integrity and good sealing. On the internal connection structure, by pouring concrete, the concrete can fill the internal space. The connecting hole 7 can not only reduce the dead weight of the wall panel, but also enable the concrete to be interspersed in the connecting panel to ensure the integrity of the structure.

[0049] During the specific construction, this embodiment also provides a method for constructing cast-in-situ wall components for building construction, comprising the following steps:

[0050] Step 1: Site leveling and layout

[0051] Level the construction site and lay out the wall construction line; when laying out the construction line, lay out the vertical reinforcement and the outer contour of the wall to provide a benchmark for the foundation structure construction;

[0052] Step 2: Construction of foundation wall

[0053] A foundation trench is excavated according to the construction line. The bottom of the foundation wall 17 has an enlarged base 18. The base 18 is placed in the foundation trench and fixed in the foundation trench with anchor bolts. Then, vertical reinforcement 15 is arranged in the foundation trench. The vertical reinforcement 15 is located inside the foundation wall 17. Then, concrete is placed in the foundation trench and cured.

[0054] Step 3: Place wall components

[0055] Place the wall component on the foundation wall 17, then arrange the transverse reinforcement in the upper groove 5 and the lower groove 6, and connect the transverse reinforcement and the vertical reinforcement together through connectors;

[0056] Step 4: Construction of horizontal clamping members

[0057] Arrange a horizontal clamping member between two adjacent wall components. First, adjust the distance between the two limit blocks so that they can enter the limit groove. Then operate the connecting sleeve to shorten the distance between the limit blocks at both ends to ensure the connection and sealing of the two wall components.

[0058] Step 5: Arrange wall components in sequence

[0059] The installation sequence is to construct the wall components in sequence to form a continuous wall structure;

[0060] Step 6: Pour concrete

[0061] Pour concrete into the gap between the side panels and vibrate.

[0062] The idea of ​​this embodiment is to use an integral prefabricated concrete as a formwork to construct the wall, so that it can be used as part of the structure after construction is completed without having to be dismantled. In order to ensure the connectivity of the structure, a connecting plate is arranged between the side panels, so that the left and right side panels have good connection strength. In order to facilitate construction, this embodiment is constructed in sections, and the sections are butt-jointed. The horizontal walls are reinforced and connected by horizontal clamping members in the structure to ensure the sealing of the butt joints. In the vertical direction, due to the dead weight of the structure, a certain connection structure is applied, such as a bottom plate is arranged at intervals at the bottom of the side panels, and the bottom plates are connected by bolts, so that the vertical butt joints also have good sealing, and connecting holes are provided on the connecting plates. After pouring concrete, the concrete can be inserted into the wall panel structure. The structural connection strength is high, and there is no need to remove the formwork during use. It is easy to use, the connection between the steel frame and the connecting plate is stable, the structural connection strength is large, and the sealing between the assembled wall panels is good to avoid leakage, thereby improving construction efficiency and shortening construction period. The outer wall of the wall is preset in advance to avoid the occurrence of wall cracks.

[0063] Example 2: This example further illustrates the installation structure of the wall panel.

[0064] This embodiment Figure 6 As shown in the figure, a reinforcement column 19 is provided on the connecting plate 2. The reinforcement column 19, the upper transverse reinforcement 13, the lower transverse reinforcement 14 and the vertical reinforcement 15 are connected together by a ring-shaped wire 20, and the reinforcement columns on the upper and lower connecting plates are connected together by stirrups 21.

[0065] This structure can establish a connection between the upper and lower connecting plates 2, and at the same time connect the steel skeleton and the wall together. The structural connection has high integrity, which avoids the displacement of the steel bars during pouring and construction, ensures that the steel bars are arranged in the center of the wall, and provides a better internal frame foundation for the structure. Furthermore, in this embodiment, a U-shaped connecting groove is provided inside the side panel. After pouring concrete, this structure can enable the side panel to be hooked and connected to the concrete to ensure the stability of the connection.

[0066] Example 3: This example further illustrates the specific structure of the side panels.

[0067] During construction of this embodiment, the inner wall of the side panel 1 can also be roughened to make the inner wall have an uneven plane structure, thereby increasing the connection with the concrete and making the structure vertically connected with the newly poured concrete. In order to further improve the strength of the structure, a plurality of alternately arranged ribs 22 can be provided on the inner wall of the side panel. The ribs 22 are as follows: Figure 7 As shown in the figure, the ribs 22 are arranged in the horizontal direction, thereby forming a constraint in the vertical direction. When the inner cavity of the concrete side panel is poured and solidified, an integral structure is formed. The rib 22 structure can create a hook connection between the side panel 1 and the integral concrete. In order to enhance this effect, the ribs can also be arranged on the connecting plate 2 to generate a force between the wall panel as a whole and the integral concrete.

[0068] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. The basic concept of the present invention is to use concrete wall panels as formwork, which does not require demolding during use and is easy to use. The connection between the steel skeleton and the connecting plate is stable, the structural connection is strong, and the sealing between the assembled wall panels is good, which avoids leakage, improves construction efficiency, shortens the construction period, and the wall exterior is pre-set to avoid the occurrence of wall cracks. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
