Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete pouring formwork, in particular to a concrete pouring formwork suitable for long and narrow small space. BACKGROUND

[0002] In order to improve the utilization rate of land resources, the layout form of sewage treatment plant has developed from the initial full ground type to semi-underground and full-underground type. In the construction of semi-underground and full-underground sewage treatment plants, there are many long and narrow small spaces. In order to facilitate the installation and removal of the formwork, a pouring formwork system suitable for planar narrow space is usually used.

[0003] In the related art, a one-way formwork assembly suitable for concrete construction in planar narrow space is disclosed in Chinese patent document CN115822249A, which includes a formwork unit, a formwork installation and fixing mechanism, and a one-way prestressing mechanism. The formwork unit includes two groove-shaped formworks and a plurality of foldable formworks. Two openings are formed between the two groove-shaped formworks, and the plurality of foldable formworks are used to block the two openings. The groove-shaped formwork edge is provided with a batten part lap joint slope. The foldable formwork includes two second vertical plates hinged together by a vertical hinge shaft. The second vertical plate of the foldable formwork is provided with a plate body part lap joint slope for lap joint with the batten part lap joint slope. The formwork installation and fixing mechanism includes an upper connecting plate and a lower horizontal support rod. The upper connecting plate is clamped between the two groove-shaped formworks. The lower horizontal support rod includes a left rod body connected to one side of the groove-shaped formwork, a threaded tube threadedly connected to the left rod body, and a right rod body threadedly connected to the other end of the threaded tube. The other end of the right rod body is connected to the other groove-shaped formwork. The threads at both ends of the threaded tube are opposite in direction. By rotating the threaded tube, the distance between the two groove-shaped formworks can be increased or shortened. The one-way prestressing mechanism includes a vertical force transmission rod, a vertical threaded rod threadedly connected to the upper connecting plate, and a connecting rod hinged to the vertical force transmission rod. The connecting rod is used to hinge with any one of the second vertical plates of the foldable formwork. In use, the foldable formwork is adjusted by the one-way prestressing mechanism to close the opening, and then the entire formwork system is hoisted into the planar narrow space. The formwork cooperates with other objects to form a mold cavity for pouring the long and narrow space wall. Concrete is poured into the mold cavity, and the formwork system is removed after pouring is completed.

[0004] In the related art, the length of the foldable formwork after unfolding is fixed, which limits the distance between the two groove-shaped formworks during concrete pouring. Therefore, the formwork system can only be used for one size of long and narrow small space. When the length of the pouring space changes, the original formwork system is no longer applicable, and the application range is small. Invention content

DETAILED DESCRIPTION

[0021] The following will be combined Figures 1-3 to make a further detailed description of the present application.

[0022] The embodiment of the present application discloses a concrete pouring formwork suitable for a narrow and long small space. Referring to Figure 1The concrete pouring formwork suitable for long and narrow small space comprises a groove type formwork 1 and a plurality of foldable formworks 2, the groove type formwork 1 is two, and the foldable formwork 2 is multiple, each foldable formwork 2 comprises two vertical plates 21 hingedly connected with each other in the vertical direction, wherein the specific hinge connection form of the two vertical plates 21 is the same as that in the related art. In order to facilitate the abutting and fixing between the foldable formwork 2 and the two groove type formworks 1, in the embodiment of the present application, the remaining structure is designed to be the same as that in the related art, but the upper connecting plate 14 is designed as an expansion plate and the expansion direction is parallel to the arrangement direction of the two groove type formworks 1, so as to adapt to the spacing adjustment between the two groove type formworks 1, the upper connecting plate 14 comprises three plate bodies 141 connected in sequence and slidably, and the vertical threaded rods in the one-way prestressing mechanism are threaded on the middle plate body 141; in other embodiments, the foldable formwork 2 can also be abutted and fixed between the two groove type formworks 1 by means of bolt fixing and the like.

[0023] With reference to Figure 1 and Figure 2 , a limiting block 15 is fixed on the vertical plate 21 of the two vertical plates 21 hingedly connected with the connecting rod in the one-way prestressing mechanism, the limiting block 15 extends towards the other side vertical plate 21, so that when the two vertical plates 21 are located in the same plane, the side of the vertical plate 21 not connected with the limiting block 15 abuts against the limiting block 15 away from the concrete pouring, facilitating the unfolding and fixing of the foldable formwork 2 during the pouring of concrete.

[0024] With reference to Figure 1 and Figure 2 , the side of the two vertical plates 21 away from each other is provided with a first plate body part lap joint inclined surface 4 for abutting and cooperating with the lap joint inclined surface 3 on the upper edge strip part of the groove type formwork 1, specifically, the distance from the first plate body part lap joint inclined surface 4 to the hinge connection place of the two vertical plates 21 gradually increases away from the concrete pouring side. The foldable formwork 2 further comprises an extension plate 5, the extension plate 5 corresponds to the vertical plate one by one, the first supporting rod 8 is fixed on the side of the two vertical plates 21 away from the concrete pouring, and the extension plate 5 is hingedly connected to the corresponding first supporting rod 8, specifically, the second supporting rod 9 is fixed on the side of the extension plate 5 away from the concrete pouring, one end of the second supporting rod 9 away from the extension plate 5 is hingedly connected to one end of the first supporting rod 8 away from the corresponding vertical plate 21, and the hinge axis of the second supporting rod 9 is parallel to the hinge axis of the two vertical plates 21. The hinge connection of the vertical plate 21 and the corresponding extension plate 5 is realized through the first supporting rod 8 and the second supporting rod 9, facilitating the rotation of the extension plate 5, so as to facilitate the close abutment on the corresponding vertical plate 21.

[0025] With reference to Figure 1 and Figure 2, one side of the extension plate 5 is provided with a second plate body part lap slope 6 for abutting with the first plate body part lap slope 4 on the corresponding vertical plate 21, and the other side is provided with a third plate body part lap slope 7 for abutting with the groove-shaped formwork 1 upper edge strip part lap slope 3, so that the cross section of the extension plate 5 is parallelogram; The side of the vertical plate 21 away from the concrete pouring is provided with a limiting piece, which is used to fix the extension plate 5 and the corresponding vertical plate 21 when the second plate body part lap slope 6 on the extension plate 5 abuts with the first plate body part lap slope 4 on the corresponding vertical plate 21. When the second plate body part lap slope 6 on the extension plate 5 abuts with the first plate body part lap slope 4 on the corresponding vertical plate 21, the extension plate 5 and the corresponding vertical plate 21 are located in the same plane.

[0026] Because the size of the narrow and long small pouring space is usually pre-set in several specifications in construction, when the length of the pouring space is pre-set in small specifications, the extension plate 5 is rotated towards the direction close to the center of the groove-shaped formwork 1, so that the extension plate 5 is rotated to the side of the corresponding vertical plate 21 away from the concrete pouring, thereby not affecting the abutting of the first plate body part lap slope 4 on the vertical plate 21 and the groove-shaped formwork 1 upper edge strip part lap slope 3, forming a small specification size formwork system.

[0027] When the length of the pouring space is pre-set in larger specifications, the groove-shaped formworks 1 are adjusted to be away from each other to adapt to the length of the larger specification pouring space, then the extension plate 5 corresponding to one side of the vertical plate 21 is rotated towards the direction away from the center of the groove-shaped formwork 1, so that the second plate body part lap slope 6 of the extension plate 5 is abutted with the first plate body part lap slope 4 on the corresponding vertical plate 21, at this time the extension plate 5 and the corresponding vertical plate 21 are located in the same plane, then the limiting piece is used to fix the extension plate 5 and the corresponding vertical plate 21, thereby extending the length of the foldable formwork 2 when it is unfolded, and the plate body 141 at the middle position of the upper connecting plate 14 can drive the foldable formwork 2 to move to abut between the two groove-shaped formworks 1, thereby forming a larger specification size formwork system.

[0028] When the length of the pouring space is pre-set in larger specifications, the groove-shaped formworks 1 are adjusted to be away from each other to adapt to the length of the larger specification pouring space, then the extension plate 5 corresponding to one side of the vertical plate 21 is rotated towards the direction away from the center of the groove-shaped formwork 1, so that the second plate body part lap slope 6 of the extension plate 5 is abutted with the first plate body part lap slope 4 on the corresponding vertical plate 21, at this time the extension plate 5 and the corresponding vertical plate 21 are located in the same plane, then the limiting piece is used to fix the extension plate 5 and the corresponding vertical plate 21, thereby extending the length of the foldable formwork 2 when it is unfolded, and the plate body 141 at the middle position of the upper connecting plate 14 can drive the foldable formwork 2 to move to abut between the two groove-shaped formworks 1, thereby forming a larger specification size formwork system.

[0029] With reference to Figure 2 and Figure 3 , the second supporting rod 9 is aligned with the hinge of the corresponding first supporting rod 8 on the side of the first plate body part of the vertical plate 21 away from the hinge of the two vertical plates 21, so that when the second plate body part of the extension plate 5 is in abutment with the first plate body part of the corresponding vertical plate 21, the first supporting rod 8 and the second supporting rod 9 form a stable triangle, thereby improving the structural stability of the extension plate 5 after being fixed relative to the corresponding vertical plate 21; at the same time, the extension plate 5 will not interfere with the corresponding vertical plate 21 when it rotates towards the direction close to the center of the groove-shaped formwork 1 (see Figure 1 ).

[0030] With reference to Figure 2 and Figure 3 , in order to facilitate the relative fixation of the extension plate 5 and the corresponding vertical plate 21 when the second plate body part of the extension plate 5 is in abutment with the first plate body part of the corresponding vertical plate 21, a connecting rod (not shown in the figure) is fixed to the side of the vertical plate 21 away from the concrete pouring, and the limiting member includes a limiting plate 10, which is rotatably sleeved on the connecting rod, and the rotation axis of the limiting plate 10 is perpendicular to the plane of the corresponding vertical plate 21, and the limiting plate 10 is used to abut against the side of the extension plate 5 close to the second supporting rod 9, and when the limiting plate 10 abuts against the side of the extension plate 5 away from the concrete pouring, the second plate body part of the extension plate 5 is in abutment with the first plate body part of the corresponding vertical plate 21.

[0031] When the extension plate 5 rotates to the position where the second plate body part of the extension plate 5 is in abutment with the first plate body part of the corresponding vertical plate 21, the limiting plate 10 is rotated towards the direction close to the extension plate 5, so that the limiting plate 10 abuts against the side of the extension plate 5 away from the concrete pouring, and the rotation of the extension plate 5 is limited under the abutment of the limiting plate 10 and the vertical plate 21, thereby achieving the relative fixation of the extension plate 5 and the corresponding vertical plate 21, so that the extension plate 5 and the vertical plate 21 will not shake during the pouring of concrete.

[0032] With reference to Figure 2 and Figure 3 , the side of the limiting plate 10 close to the vertical plate 21 is bonded with a cushion layer 11 having elasticity, and the cushion layer 11 is used to abut against the side of the extension plate 5 close to the second supporting rod 9, and specifically, the cushion layer 11 is one of a rubber layer, a plastic layer, and a silica gel layer. By abutting the cushion layer 11 having elasticity against the side of the extension plate 5 close to the second supporting rod 9, stress can be provided to the extension plate 5, the abutment effect between the extension plate 5 and the corresponding vertical plate 21 is enhanced, and the friction between the limiting plate 10 and the vertical plate 21 and the extension plate 5 is increased, so that the limiting plate 10 is not prone to unnecessary rotation.

[0033] With reference to Figure 2 andFigure 3 The fixed rod 12 is a rubber rod and can be moved according to the deviation, and the end of the fixed rod 12 away from the vertical plate 21 is provided with a suction member for adsorbing the corresponding side extension plate 5.

[0034] With reference to Figure 2 and Figure 3 In order to adsorb and fix the extension plate 5, the suction member includes a suction disc 13 fixed at the end of the fixed rod 12 away from the vertical plate 21, and the suction disc 13 is used to adsorb the corresponding side extension plate 5. Specifically, the suction disc 13 is a rubber suction disc.

[0035] When the extension plate 5 is not used, it is rotated by 180° towards the direction close to the channel-shaped formwork 1, so that the extension plate 5 is parallel to the corresponding vertical plate 21, and at this time, the side of the extension plate close to the second supporting rod 9 abuts against the suction disc 13, so that the suction disc 13 adsorbs the extension plate 5, thereby preventing the extension plate 5 from shaking unnecessarily when the vertical plate 21 is used.

[0036] The implementation principle of the embodiment is as follows: in construction, the size of the narrow and long small pouring space is usually several preset specifications. When the length of the pouring space is a preset small specification, the two extension plates 5 are rotated towards the direction close to the center of the channel-shaped formwork 1, so that the extension plates 5 are rotated to the side away from the concrete pouring of the corresponding vertical plate 21 and are parallel to each other, and the extension plates 5 are adsorbed and fixed by the suction disc 13, thereby not affecting the abutting cooperation between the first plate body part lap joint inclined surface 4 on the vertical plate 21 and the edge strip part lap joint inclined surface 3 on the channel-shaped formwork 1, and forming a small specification size formwork system between the channel-shaped formwork 1 and the foldable formwork 2.

[0037] When the length of the pouring space is a preset large specification, the two channel-shaped formworks 1 are moved away from each other to the required position by adjusting the threaded pipe on the lower horizontal supporting rod, so as to adapt to the length of the large specification pouring space, then the extension plate 5 corresponding to one side of the vertical plate 21 is separated from the corresponding suction disc 13, and is rotated towards the direction away from the center of the channel-shaped formwork 1, so that the extension plate 5 is rotated to the second plate body part lap joint inclined surface 6 abutting against the first plate body part lap joint inclined surface 4 on the corresponding vertical plate 21, at this time, the extension plate 5 and the corresponding vertical plate 21 are located in the same plane, then the limiting plate 10 on the corresponding side is rotated, so that the cushion layer 11 on the limiting plate 10 abuts against the side of the extension plate 5 close to the second supporting rod 9, and the extension plate 5 and the corresponding vertical plate 21 are relatively fixed, thereby lengthening the length of the foldable formwork 2 when it is unfolded, and the plate body 141 at the middle position of the upper connecting plate 14 can drive the foldable formwork 2 to move, so that the third plate body part lap joint inclined surface 7 abuts against the edge strip part lap joint inclined surface 3 of the channel-shaped formwork 1, thereby forming a large specification size formwork system.

[0038] When the length of the pouring space is a preset large size, the channel-shaped formwork 1 is moved away from each other to adapt to the length of the large size pouring space, then the extension plates 5 corresponding to the two side vertical plates 21 are both rotated towards the direction away from the center of the channel-shaped formwork 1, so that the extension plates 5 are rotated to the second plate body part overlapping bevel 6 abutting against the first plate body part overlapping bevel 4 on the corresponding vertical plate 21, then the limiting plate 10 corresponding to one side is rotated, so that the cushion layer 11 on the limiting plate 10 abuts against the side of the corresponding extension plate 5 close to the second supporting rod 9, the extension plate 5 is relatively fixed with the corresponding vertical plate 21, thereby further lengthening the length of the foldable formwork 2 when unfolded, the plate body 141 at the middle position of the upper connecting plate 14 can drive the foldable formwork 2 to move, so that the third plate body part overlapping bevel 7 abuts against the edge strip part overlapping bevel 3 of the channel-shaped formwork 1, thereby forming a large size formwork system, so that the foldable formwork 2 can be applied to pouring in small spaces of different length and size, which helps to expand the application range of the formwork system.

[0039] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
