[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0028] The present invention will be further described below with reference to the embodiments.
[0029] Embodiment: A composite board for concrete without demolition, such as Figure 1-5 As shown, it includes a bottom plate 1 and two sets of side plates 2. The two sets of side plates 2 and the bottom plate 1 are an integrally formed structure. The side view projection shape of the two sets of side plates 2 and the bottom plate 1 is U-shaped;
[0030] An outer hanging plate 21 is provided at the lower end of the side panel 2, and an inner hanging plate 22 is provided at the upper end of the side panel 2. When multiple groups of composite panels are stacked, the outer hanging plate 21 at the lower end of the upper side panel 2 is clamped on the inner hanging plate 22 at the upper end of the lower side panel 2.
[0031] In the present invention, by respectively arranging an inner hanging plate 22 and an outer hanging plate 21 at the upper and lower ends of the side panels 2, when the multi-layer composite panels are stacked to form a wall model, the inner hanging plate 22 on the lower composite panel is stuck in the outer hanging plate 21 below the upper composite panel, and the upper and lower composite panels can be conveniently aligned and fixed without using bolts and other connecting parts, so that the outer formwork composite panels of the wall can be quickly constructed, and then concrete can be quickly injected to build the wall.
[0032] Furthermore, it includes two limiting protrusions 11 , both of which are fixedly arranged below the bottom plate 1 , and forming limiting grooves 102 between the limiting protrusions 11 and the external panels 21 below the two side panels 2 .
[0033] Among them, by setting a limiting protrusion 11, a limiting function can be formed between the limiting protrusion 11 and the outer hanging plate 21 to limit the inner hanging plate 22 of another group of composite panels, thereby avoiding relative displacement between the outer hanging plate 21 of the upper composite panel and the inner hanging plate 22 of the lower composite panel during use, and avoiding severe shaking of the entire wall outer formwork composite panel during the pouring process.
[0034] Furthermore, the width of the limiting groove 102 is slightly greater than the thickness of the inner hanging plate 22 .
[0035] Furthermore, a first grouting hole 103 and a second grouting hole 104 are provided on the bottom plate 1 at intervals, and the first grouting hole 103 and the second grouting hole 104 are used for concrete to flow downward.
[0036] In particular, during use, the first grouting hole 103 and the second grouting hole 104 can also allow the steel structure of the cast wall to pass through, which is more in line with the construction structure of the cast wall.
[0037] Furthermore, a plurality of grooves 201 are provided at intervals in the upper and lower parts of the inner wall of the side panel 2 , and the grooves 201 are distributed along the length direction of the side panel 2 .
[0038] Among them, by providing the grooves 201 on the inner walls of the side panels 2, the two side surfaces of the cast wall can present a partially raised structure, so that the wall has better anti-bending moment capacity in the width direction.
[0039] Furthermore, the side view projection shape of the groove 201 is an isosceles trapezoid, which can make the side panel 2 fit more closely to the wall after the wall is cast, and prevent the side panel 2 from easily separating from the wall.
[0040] Furthermore, the outer wall of the side panel 2 is also provided with a plurality of grooves 201 at intervals up and down, and the grooves 201 on the inner wall of the side panel 2 and the grooves 201 on the outer wall are staggered up and down.
[0041] Furthermore, a support through hole 101 is formed at the connection between the bottom plate 1 and the side plate 2 , and the inner wall height of the support through hole 101 is between one fifth and one sixth of the height of the side plate 2 .
[0042] Among them, by forming a supporting through hole 101 at the connection between the bottom plate 1 and the side plate 2, the outer wall of the supporting through hole 101 is equivalent to the rib between the bottom plate 1 and the side plate 2, which can increase the supporting effect of the bottom plate 1 on the side plate 2, and can avoid the upper end of the side plate 2 from expanding seriously to both sides during the pouring process, thereby avoiding deformation of the poured wall.
[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
