Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to a cantilevered cast-in-place concrete structure construction frame for a high-rise building. Background Art

[0002] At present, more and more high-rise buildings have cantilevered concrete structures. Due to their high position, heavy structure, and high safety risks in edge operations, their formwork and construction are difficult, and conventional construction techniques such as formwork and protective scaffolding cannot be implemented.

[0003] In the related art, scaffolding is usually used as the formwork support for cantilevered concrete structures; the scaffolding is built of multiple horizontal, longitudinal, and vertical steel pipes that are interlaced and fixed by clamps. The concrete casting template is placed and fixed on the top of the scaffolding. For cantilevered concrete structures, the corresponding casting mold is in the shape of a long box. The top of the scaffolding is arranged with multiple horizontally arranged horizontal pipes, and the length direction of the horizontal pipes is perpendicular to the length direction of the casting mold, so that all the horizontal pipes are simultaneously abutted against the bottom of the casting mold to support it.

[0004] If the arrangement of the horizontal tubes is dense, the force on the casting mold will be more uniform and the support stability will be higher, but the operation process of building the scaffolding will be more cumbersome; if the arrangement of the horizontal tubes is loose, the interval space between adjacent horizontal tubes is larger, the scaffolding has fewer support force points on the casting mold, and the pressure per unit contact area is larger. As the casting process proceeds, the casting mold is prone to deflection-type deformation. Summary of the invention

[0005] In order to improve the above problems, the present application provides a cantilevered cast-in-place concrete structure construction frame for a high-rise building.

[0006] The present application provides a high-rise building cantilever cast-in-place concrete structure construction frame adopts the following technical solution: A construction frame for a cantilevered cast-in-place concrete structure of a high-rise building includes a scaffolding, wherein the scaffolding includes a plurality of mutually parallel supporting transverse tubes, wherein the supporting transverse tubes are located at the top of the scaffolding, and the plurality of supporting transverse tubes are arranged in a direction, wherein the arrangement direction is perpendicular to the length direction of the supporting transverse tubes, and an auxiliary reinforcing tube is also provided on the scaffolding and between each two adjacent supporting transverse tubes, wherein the auxiliary reinforcing tube and the supporting transverse tube are relatively fixed, wherein the length direction of the auxiliary reinforcing tube is perpendicular to the length direction of the supporting transverse tube, and the supporting transverse tube and the auxiliary reinforcing tube are simultaneously in contact with the bottom of a casting mold.

[0007] By adopting the above technical solution, the space between two adjacent supporting transverse tubes also has the function of supporting the casting formwork, thereby increasing the overall supporting area, making the supporting effect on the supported casting mold more evenly distributed and the supporting state more stable.

[0008] Preferably, the auxiliary reinforcement tube and the supporting cross tube are both round tubes, the radial dimensions of the auxiliary reinforcement tube and the supporting cross tube are consistent, and a matching arc groove is opened at the end of the auxiliary reinforcement tube, and the groove surface of the matching arc groove is in close contact with the side wall of the supporting cross tube.

[0009] By adopting the above technical solution, when the auxiliary reinforcement pipe is located at the same height as the supporting cross pipe, the upper surfaces of the two are flush, and the arc groove improves the fitting stability of the two and also increases the size of the abutment area between the top of the scaffolding and the casting mold.

[0011] By adopting the above technical solution, when the mounting pin is inserted into the mounting hole, the auxiliary reinforcement tube and the supporting cross tube cannot move relative to each other, thereby improving the relative stability of the auxiliary reinforcement tube and the supporting cross tube.

[0012] Preferably, the auxiliary reinforcement tube is provided with a mounting spring, one end of the mounting spring is connected to the auxiliary reinforcement tube, and the other end is connected to the mounting pin, the telescopic direction of the mounting spring is consistent with the sliding direction of the mounting pin, and in a natural state, the mounting spring applies a thrust toward the supporting cross tube to the mounting pin; an operating rod is slidably arranged on the auxiliary reinforcement tube, the sliding direction of the operating rod is parallel to the sliding direction of the mounting pin, the length direction of the operating rod is consistent with the length direction of the supporting cross tube, a long stroke hole is opened on the tube wall of the auxiliary reinforcement tube, the length direction of the long stroke hole is parallel to the length direction of the auxiliary reinforcement tube, the operating rod passes through the long stroke hole, and the operating rod and the mounting pin are relatively fixed.

[0013] By adopting the above technical solution, the operating rod allows the operator to slide and control the installation pin rod from the outside of the auxiliary reinforcement tube, and the long stroke hole limits the movement stroke of the operating rod and the installation pin rod.

[0014] Preferably, a cross reinforcing rib rod is provided in the auxiliary reinforcing tube, a matching slide groove is opened on the inner wall of the auxiliary reinforcing tube, the length direction of the matching slide groove is consistent with the length direction of the auxiliary reinforcing tube, and the edge of the cross reinforcing rib rod is embedded in the matching slide groove.

[0015] By adopting the above technical solution, the cross reinforcement rod inside the auxiliary reinforcement tube plays a role of strength support for the auxiliary reinforcement tube, thereby improving the structural stability of the auxiliary reinforcement tube.

[0017] By adopting the above technical solution, the auxiliary reinforcement tube is set separately, and the two halves of the molecular tube move axially relative to each other, which can change the overall length of the auxiliary reinforcement tube, thereby facilitating the operation of placing the auxiliary reinforcement tube between the two supporting cross tubes.

[0021] Since the contour of the matching arc groove is an arc, when the auxiliary reinforcement tube is subjected to downward pressure, the abutment force of the supporting cross tube on the semi-molecular tube causes the auxiliary reinforcement tube to have a shortening trend. By adopting the above technical solution, a locking piece is inserted into the anti-retraction socket to form a anti-retraction limit for the installation pin rod. The installation pin rod has a higher stability relative to the supporting cross tube, and the installation pin rod forms a movable limit for the auxiliary reinforcement tube through the limiting abutment block, thereby achieving the purpose of making the auxiliary reinforcement tube and the supporting cross tube relatively fixed.

[0030] The following is combined with Figure 1-4 This application is described in further detail.

[0031] The present application embodiment discloses a cantilever cast-in-place concrete structure construction frame for a high-rise building, such as Figure 1 As shown, the scaffold 1 includes a plurality of mutually parallel support transverse tubes 11, which are located at the top of the scaffold 1 and are used to directly support and abut the casting mold. The length directions of all the support transverse tubes 11 are parallel, and each support transverse tube 11 is arranged horizontally, and the arrangement direction is perpendicular to the length direction of the support transverse tube 11; an auxiliary reinforcement tube 2 is also provided on the scaffold 1 and between each two adjacent support transverse tubes 11, and the auxiliary reinforcement tube 2 fills the space between the two adjacent support transverse tubes 11, and the auxiliary reinforcement tube 2 also directly supports and abuts the casting mold.

[0032] like Figure 1 , 2As shown in Figure 3, a cross reinforcing rib rod 25 is provided inside the auxiliary reinforcing tube 2, and the length direction of the cross reinforcing rib rod 25 is consistent with the length direction of the auxiliary reinforcing tube 2; a single auxiliary reinforcing tube 2 includes two coaxial half-molecular tubes 22, and a matching slide groove 24 is provided on the inner wall of the half-molecular tube 22, and the length direction of the matching slide groove 24 is consistent with the length direction of the auxiliary reinforcing tube 2, and the edge of the cross reinforcing rib rod 25 is embedded in the matching slide groove 24, so that the half-molecular tube 22 can slide relative to the cross reinforcing rib rod 25. A connecting partition 26 is fixedly connected to the inner wall of the half-molecular tube 22, and the plate surface of the connecting partition 26 is perpendicular to the axis of the auxiliary reinforcing tube 2, and a residual spring 252 is connected between the connecting partition 26 and the cross reinforcing rib rod 25, and one end of the residual spring 252 is fixedly connected to the connecting partition 26, and the other end is fixedly connected to the end of the cross reinforcing rib rod 25. A limiting bolt 251 is threadedly connected to the cross reinforcing rib rod 25, and the axis of the limiting bolt 251 is perpendicular to the length direction of the cross reinforcing rib rod 25. A limiting waist-shaped hole 221 is opened on the tube wall of the half-molecular tube 22, and the length direction of the limiting waist-shaped hole 221 is parallel to the axis of the half-molecular tube 22. The limiting waist-shaped hole 221 is for the limiting bolt 251 to pass through; that is, the relative sliding stroke of the half-molecular tube 22 and the cross reinforcing rib rod 25 is consistent with the sliding stroke of the limiting bolt 251 in the limiting waist-shaped hole 221.

[0033] like Figure 1 , 2 As shown in Figures 3 and 4, the length direction of the auxiliary reinforcement tube 2 is horizontal and perpendicular to the length direction of the supporting transverse tube 11, and the number of auxiliary reinforcement tubes 2 between two adjacent supporting transverse tubes 11 is three. The auxiliary reinforcement tube 2 and the supporting transverse tube 11 are both round tubes, and the radial dimensions of the auxiliary reinforcement tube 2 and the supporting transverse tube 11 are consistent. The ends of the auxiliary reinforcement tube 2 are provided with matching arc grooves 21, and the groove surfaces of the matching arc grooves 21 are in close contact with the side walls of the supporting transverse tube 11; in a natural state, when the two ends of the auxiliary reinforcement tube 2 are in contact with the supporting transverse tubes 11 on both sides, the residual spring 252 is in a compressed state. The limiting waist-shaped hole 221 and the limiting bolt 251 are both located on the lower side of the auxiliary reinforcement tube 2, and the upper edges of each auxiliary reinforcement tube 2 and each supporting transverse tube 11 are flush.

[0034] like Figure 2 , 3As shown in FIG. 4 , the auxiliary reinforcement tube 2 is provided with a mounting pin 3 slidingly disposed at the end portion thereof facing the supporting transverse tube 11. The sliding direction of the mounting pin 3 is consistent with the length direction of the auxiliary reinforcement tube 2. A mounting hole 12 for inserting the mounting pin 3 is provided on the side tube wall of the supporting transverse tube 11. A mounting spring 33 is disposed in the half-molecule tube 22. One end of the mounting spring 33 is fixedly connected to the side of the connecting partition 26 away from the cross reinforcing rib rod 25, and the other end is fixedly connected to the mounting pin 3. The telescopic direction of the mounting spring 33 is consistent with the sliding direction of the mounting pin 3. The end of the mounting pin 3 facing the cross reinforcing rib rod 25 passes through the connecting partition 26 and is fixedly connected to the limiting stop block 31. In a natural state, the mounting spring 33 applies a thrust to the mounting pin 3 toward the supporting transverse tube 11, and the limiting stop block 31 abuts against the side of the connecting partition 26 away from the supporting transverse tube 11.

[0035] like Figure 2 and 3 As shown, an operating rod 34 is slidably provided on the auxiliary reinforcement tube 2, and the operating rod 34 is used by the operator to slide and control the installation pin 3 from the outside of the auxiliary reinforcement tube 2. The sliding direction of the operating rod 34 is parallel to the sliding direction of the installation pin 3, and the length direction of the operating rod 34 is consistent with the length direction of the supporting transverse tube 11. A long stroke hole 23 is opened on the tube wall of the auxiliary reinforcement tube 2, and the length direction of the long stroke hole 23 is parallel to the length direction of the auxiliary reinforcement tube 2. A single operating rod 34 simultaneously passes through the long stroke holes 23 of three mutually parallel half-molecular tubes 22, and is fixedly connected to the installation pins 3 in these three half-molecular tubes 22. In a natural state, the operating rod 34 is located at one end of the long stroke hole 23 close to the supporting transverse tube 11; when the operator applies a thrust to the operating rod 34, so that the operating rod 34 is located at one end of the long stroke hole 23 away from the supporting transverse tube 11, the installation pin 3 is completely located in the half-molecular tube 22.

[0036] like Figure 1 , 3As shown in Figure 4, when the end of the auxiliary reinforcement tube 2 abuts the supporting transverse tube 11, since the profile of the matching arc groove 21 is arc-shaped, when the auxiliary reinforcement tube 2 is subjected to downward pressure, the abutting force of the supporting transverse tube 11 on the semi-molecular tube 22 causes the auxiliary reinforcement tube 2 to have a tendency to shorten. A stop hole 32 is provided on the side wall of one end of the mounting pin 3 inserted into the supporting transverse tube 11, and the hole axis of the stop hole 32 is consistent with the length direction of the supporting transverse tube 11. A locking piece is provided in the supporting transverse tube 11, and the locking piece is used to insert the stop hole 32 to stop the mounting pin 3. A locking slider 4 is provided in the supporting cross tube 11, and the locking slider 4 slides relative to the supporting cross tube 11, and the sliding direction is consistent with the length direction of the supporting cross tube 11. A locking screw 42 is threadedly connected to the supporting cross tube 11, and the locking screw 42 and the supporting cross tube 11 are coaxially rotatably connected. The locking member is a locking pin 41, and the locking pin 41 is fixedly connected to the locking slider 4, and the length direction of the locking pin 41 and the supporting cross tube 11 are consistent; in a natural state, when the mounting pin 3 is inserted into the mounting hole 12, the anti-retraction socket 32 ​​is located in the space inside the supporting cross tube 11, and a single locking pin 41 and an anti-retraction socket 32 ​​are coaxially aligned. After rotating the locking screw 42, the locking slider 4 moves, and each locking pin 41 is respectively inserted into its corresponding anti-retraction socket 32, so that each mounting pin 3 cannot move.

[0037] The implementation principle of a cantilever cast-in-place concrete structure construction frame of a high-rise building in the embodiment of the present application is as follows: After the scaffolding 1 is built, the auxiliary reinforcement tube 2 is installed between each supporting cross tube 11, and the auxiliary reinforcement tube 2 is shortened and the installation pin 3 is retracted into the auxiliary reinforcement tube 2 by applying opposite pressure to the two operating pull rods 34; when the auxiliary reinforcement tube 2 is placed at the same height as the supporting cross tube 11, the operating pull rod 34 is released, the end of the half-molecule tube 22 abuts against the supporting cross tube 11, and the installation pin 3 is inserted into the installation hole 12, and then the locking screw 42 is rotated. After each locking pin 41 is inserted into the anti-retraction socket 32, the installation and fixation of the auxiliary reinforcement tube 2 between the supporting cross tubes 11 is completed, and the casting mold is hoisted and placed on the top of the scaffolding 1.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
