Description

Technical Field

[0001] The invention belongs to the field of building construction, and specifically relates to a full-angle template positioning frame and a method for positioning the template. Background Art

[0002] With the development of the construction industry, in order to meet the design requirements of spatial functionality and structural importance, some vertical structural components such as shear walls have shear wall ends that are constrained end columns protruding from the shear walls. Some shear wall short sections or constrained end columns protruding from the shear walls even have irregular angles with the shear walls, but are in the form of special-shaped cross-sections at various angles.

[0003] At present, there are no specific and reliable design measures for effectively supporting and fixing the constrained end columns of short limbs and protruding shear walls to the formwork of shear walls. During the on-site implementation, simple steel pipes or wooden squares are usually used to temporarily support the formwork, which is quite arbitrary. As a result, after pouring concrete, the constrained end columns of short limbs and protruding shear walls often have poor forming effects such as offset or distortion due to loose formwork fixation, which affects the quality of concrete forming.

DETAILED DESCRIPTION

[0033] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0034] In this specification, the terms "vertical", "lateral", "longitudinal", "up", "down", "left", "right", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the attached Figure 2 The orientation or positional relationship shown is only for the convenience of describing the present invention, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0035] Full angle template positioning frame, such as Figure 1 and Figure 2 As shown, at least two pairs of template supports 1 are arranged in the transverse direction, and two adjacent pairs of template supports 1 are butt-jointed through connectors. After being butt-jointed, multiple pairs of template supports 1 are arranged on the outside of the template of the vertical component of the shear wall with a special cross-section, so as to support the template of the vertical component of the shear wall with a special cross-section. Each template support 1 can be a square steel pipe, or a frame of steel pipe splicing, etc.

[0036] The connector includes a socket joint 2 and a plug joint 3, and the socket joint 2 and the plug joint 3 are assembled in a socket-and-spigot manner to achieve the docking of two adjacent formwork supports 1. Figure 3 and Figure 4As shown, the socket 2 is fixed to the end of one of the template supports 1, and its cross section is semicircular. A plug-in slot 21 is provided on the socket 2, extending horizontally along the template support 1 and penetrating the outer end of the socket 2. The plug-in slot 21 penetrates the entire socket 2 along the template support 1 longitudinally. The plug-in slot 21 is used to insert the plug-in slot 3. The template support 1 takes a square steel pipe as an example, and the horizontal direction of the template support 1 is the length of the steel pipe. When the template support 1 is installed on the outer side of the vertical component template of the special-shaped shear wall, the direction perpendicular to the horizontal and vertical directions is the longitudinal direction. The outer end of the socket 2 refers to the relative position relationship. One end of the socket 2 is the inner end, and the other end is the outer end. The inner end is the end connected to the template support 1, and the outer end is opposite to the inner end. The plug-in slot 21 penetrates the outer end of the socket 2, so that a socket is formed at the outer end of the socket 2, and the plug-in slot 3 can be inserted into the plug-in slot 21 from the socket. The plug-in groove 21 passes through the entire socket 2 along the longitudinal direction of the formwork support 1, thus creating sufficient space for the plug-in connector 3 to rotate within the plane formed by the transverse and longitudinal directions of the formwork support 1.

[0037] like Figure 5 and Figure 6 As shown, the plug connector 3 is fixed to the end of another formwork support 1, and its cross section is semicircular. The plug connector 3 is plugged into the plug slot 21 of the socket 2; the plug connector 3 is rotatably connected with the socket 2 through a rotating shaft device that passes through the center of the plug connector 3 and the socket 2 in the vertical direction. The plug connector 3 has a semicircular cross section, and the socket 2 has a semicircular cross section, so that when the two rotate relative to each other, there will be no interference with other parts, and the rotation angle range is wide. When the plug connector 3 and the socket 2 are rotated to the required angle position, they need to be locked so that they can achieve the purpose of formwork support, so a locking structure is provided for locking the relative position of the plug connector 3 and the socket 2.

[0038] The rotating shaft device can directly adopt a connecting shaft, and the rotation is realized by forming a sliding pair between the outer surface of the connecting shaft and the wall of the connecting hole of the socket joint 2 and the plug joint 3. In this embodiment, the rotating shaft device includes a connecting shaft 4 and a rolling bearing 6; a circular cavity 22 is provided on the socket 2, which is vertically penetrated, and the central axis of the circular cavity 22 coincides with the central axis of the plug joint 3; the circular cavity 22 is adapted to the outer ring of the rolling bearing 6; a circular through hole 31 is provided on the plug joint 3, which is vertically penetrated, and the central axis of the circular through hole 31 coincides with the central axis of the plug joint 3; the circular through hole 31 is adapted to the connecting shaft 4; the connecting shaft 4 is vertically plugged into the circular cavity 22 of the socket 2 and the circular through hole 31 of the plug joint 3, and is surrounded by the inner wall of the circular cavity 22, the outer wall of the circular through hole 31 and the plug joint 3 to form two bearing mounting cavities located above and below the plug joint 3, the rolling bearing 6 is located in the bearing mounting cavity, its inner ring is fixed to the connecting shaft 4, and its outer ring is installed to the circular cavity 22 of the socket 2. The rolling bearing 6 can better realize the connection between the connecting shaft 4 and the plug joint 3 and the socket joint 2, facilitate the rotation between the connecting shaft 4 and the plug joint 3, reduce the friction during rotation, and help to extend the service life of the full-angle template positioning frame.

[0039] like Figure 7 As shown, the connecting shaft 4 includes a shaft portion 41 inserted into the circular through hole 31 and a circular top plate 42 fixed to the top of the shaft portion 41; a circle of connecting holes 43 are arranged around the center of the top plate 42; a threaded hole 11 is provided at the top of the template support 1 corresponding to the connecting hole 43, and the connecting screws 7 are installed in the corresponding connecting hole 43 and the threaded hole 11 to form the locking structure.

[0040] The positions and numbers of the connection holes 43 on the top plate 42 and the threaded holes 11 on the template support 1 should correspond to the angle to be adjusted. When adjusted to a certain required angle, the connection holes 43 are aligned with the threaded holes 11 at the corresponding positions. Of course, the connection holes 43 on the top plate 42 can be set as several arc-shaped strip holes.

[0041] The top plate 42 can completely protrude from the top of the socket 2. In this embodiment, the inner wall of the circular cavity 22 is provided with an inwardly protruding boss 23, and the circular cavity 22 is divided into three-stage stepped holes by the boss 23; the top plate 42 includes a top cover portion 42A and a plug-in portion 42B in the vertical direction, and the top cover portion 42A overlaps the boss 23, and the threaded hole 11 is provided on the boss 23. In this structure, the top plate 42 is installed on the socket 2 in a countersunk style, which is easy to position during installation, and more beautiful with less installation error.

[0042] The bottom end of the connecting shaft 4 is threadedly connected with a nut 5, and the nut 5 limits the inner ring of the rolling bearing 6 vertically at the bottom through a nut washer.

[0043] In order to accurately know the angle of rotation, preferably, a circular degree dial 8 is included, the degree dial 8 is coaxially arranged with the central axis of the circular cavity 22, and is installed on the top of the socket 2; an angle marking line is engraved on the outer edge of the top surface of the top plate 42. The angle marking line can be one, or it can correspond one to one with the scale on the degree dial 8. For example: when an angle marking line is set, the angle marking line is aligned with the 0 scale on the degree dial 8. At this time, the two adjacent template supports 1 are arranged in a straight line, and the angle between the two is 0°. After relative rotation occurs, the angle between the two adjacent template supports 1 after rotation can be known through the scale on the degree dial 8 aligned with the angle marking line.

[0044] The method for positioning a template using a full-angle template positioning frame includes the following steps:

[0045] Step 1: Factory-process the components required for the full-angle template positioning frame;

[0046] Step 2: Install the first and second formwork supports 1 on the outside of the formwork of the vertical component of the special-shaped cross-section shear wall, and ensure that the connection head of the formwork support 1 is aligned with the corner of the formwork;

[0047] Step 3: insert the plug connector 3 at the end of the second template support 1 into the plug slot 21 of the socket connector 2 of the previous template support 1, and adjust the center hole of the rolling bearing 6 in the socket connector 2 to align with the circular through hole 31 of the plug connector 3;

[0048] Step 4: Install the connecting shaft 4 through the rolling bearing 6 and the circular through hole 31;

[0049] Step 5: Rotate the second template support 1 to make it close to the template;

[0050] Step 6: Screw on the connecting screws 7 to fix the connecting shaft 4 and the template bracket 1.

[0051] The rolling bearing 6 is assembled into the circular cavity 22 of the socket 2 at the end of the formwork support 1 in step three or before step three.

[0052] Another construction method can be used as follows:

[0053] Step 1: Process the required components of the full-angle template positioning frame in the factory and assemble them. During assembly, only the template bracket 1 is assembled together without locking the positions of the two.

[0054] Step 2: according to the rotation angle of the template of the vertical member of the special-shaped shear wall, rotate the template support 1 so that the angle between two adjacent template supports 1 is the same as the template rotation angle, and then tighten the connecting screw 7 to lock the angle between the two adjacent template supports 1;

[0055] Step 3: Align the corner between the two formwork supports 1 with the corner of the formwork, and install the formwork support 1 to the outside of the formwork.

[0056] The above two construction methods can be selected according to actual needs.

[0057] In actual projects, a square steel pipe with a size of 10cm×10cm and a wall thickness of 5mm can be used as the formwork support 1. The socket 2 and the plug 3 are both made of solid square steel; the connecting shaft 4 is 20mm in diameter; the screw diameter is 8mm and the length is 40mm. The formwork support 1, the socket 2, the plug 3 and the connecting shaft 4 are strictly processed in the factory according to the fixed size, and the connections of each component should be tightly fitted. Of course, the components can also adopt other specifications.

[0058] When in use, square steel tubes of different lengths are selected according to the different shapes of the special-shaped shear wall vertical component formworks, and the square steel tubes are connected in sequence to form a hoop structure that surrounds the outside of the special-shaped shear wall vertical component formworks to support and reinforce the outside of the vertical component formworks, and the rigidity of the supporting rectangular tube itself is used to support and fix the formwork.

[0059] Since the joints of the formwork support 1 are connected in the form of a rotating connection of a socket joint 2 and a plug joint 3, the full-angle formwork positioning frame formed by the formwork support 1 can be flexibly adjusted. When there is a constrained end column protruding from the shear wall at the end of the shear wall, or even when the angle formed by the short end of some shear walls or the constrained end column protruding from the shear wall and the shear wall is irregular, the connector of the formwork support 1 in the full-angle formwork positioning frame disclosed by the present invention is set at the corner of the vertical component formwork, and the supporting rectangular tubes are firmly connected and the angle is adjusted through the connector, so as to effectively support and reinforce the formwork. The problem of difficult reinforcement of formworks of irregular structures in engineering is solved, the construction process is simplified, the repeated reinforcement of the part is reduced, the cost of steel pipe rental and tension screw rods is reduced, and at the same time, the construction efficiency of workers is improved, the quality of concrete pouring is guaranteed, and the later repair and rectification is reduced. It has strong applicability and can effectively support and reinforce the formwork of special-shaped vertical structures to ensure the stability of the formwork system.
