Description

Technical Field

[0001] The invention generally relates to the field of construction, and in particular to a two-way locker, a keel locking structure, a keel clamping system and a building template system. Background Art

[0002] In the construction industry, formwork technology is the most commonly used construction technology. It is closely related to the quality of concrete pouring. Formwork technology can ensure that the structure and size of the poured workpiece can fully meet the established construction requirements and standards. In traditional formwork technology, wooden formwork, plastic formwork or aluminum alloy formwork is used to surround the shape of the poured wall. Longitudinal secondary keels are fixed on the formwork at intervals, and the transverse main keels are clamped around the secondary keels to complete the formwork fixation. In recent years, assembled formwork technology has gradually become popular. The connecting plate of the formwork profile itself replaces the longitudinal secondary keel, and the transverse main keel is clamped at the end of the assembled formwork profile connecting plate.

[0003] In the above-mentioned different formwork technologies, transverse main keels, also known as keels, are required. In order to improve the efficiency of on-site formwork installation, the construction party pre-processes the transverse main keels into standard sizes, and only the standard-sized keels need to be connected at the ends on site. Due to the diversity of transverse dimensions of cast walls, the use of only standard-sized keels often cannot meet the needs, especially at the unconstrained ends of shear walls, such as door openings. The transverse main keels on both sides of the shear wall cannot be flexibly connected, resulting in low on-site construction efficiency. The complex connection method also causes material waste and increases production costs. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and to provide a two-way locker, a keel locking structure, a keel clamping system and a building formwork system that can achieve flexible connection of the keels at the unconstrained ends of the building wall, save materials and reduce production costs.

[0005] The objective of the present invention is accomplished through the following technical solution: a bidirectional locking device, comprising a pair of monomers arranged at intervals in the transverse direction and a transverse screw adjustment mechanism connecting the monomers, each of the monomers comprising a connecting portion and an adjustment portion arranged in the longitudinal direction, each of the monomers being connected with an adjustment block and a longitudinal screw adjustment mechanism, the adjustment portion being connected to the adjustment block and limiting the movement of the adjustment block in the transverse direction relative to the monomer, the longitudinal screw adjustment mechanism being connected to the adjustment portion and being able to push the adjustment block to move in the longitudinal direction relative to the monomer, and the transverse screw adjustment mechanisms being respectively arranged in a pair of the adjustment blocks.

[0006] The lateral spacing of a pair of monomers is adjusted through the transverse screw adjustment mechanism to match the outer edges of the secondary keels of the template on both sides of the wall, and the ends of the keels on both sides of the wall are respectively connected to the connecting parts of a pair of monomers. The longitudinal screw adjustment mechanism is used to push the adjustment block to move longitudinally, so that the transverse screw adjustment mechanism moves longitudinally relative to the monomer to tighten the secondary keel of the template at the end of the wall, thereby realizing flexible connection of the keel at the end of the wall, saving materials and reducing production costs.

[0007] Furthermore, in the bidirectional locking device of the present invention, the connecting portion includes a plurality of connecting holes opened in the longitudinal direction.

[0008] Furthermore, in the bidirectional locker of the present invention, a longitudinal limiting boss is formed at the intersection of the adjusting portion and the connecting portion.

[0009] Furthermore, in the bidirectional locking device of the present invention, a pair of top walls of the adjusting portion are respectively provided with longitudinal sliding grooves, the adjusting block is arranged in the adjusting portion, and the upper and lower ends of the adjusting block are respectively embedded in the longitudinal sliding grooves, so that the adjusting block can move longitudinally along the longitudinal sliding grooves relative to the monomer, and the longitudinal sliding grooves limit the movement of the adjusting block in the lateral direction relative to the monomer.

[0010] Furthermore, in the bidirectional locker of the present invention, a pair of side walls of the adjustment portion are respectively provided with transverse through grooves, and the transverse screw adjustment mechanism passes through the transverse through grooves and is penetrated in the adjustment block.

[0011] Furthermore, in the bidirectional locking device of the present invention, the lateral screw adjustment mechanism includes a lateral adjustment screw, a pair of lateral adjustment nuts are screwed on the lateral adjustment screw, and the adjustment block is provided with a lateral through-hole. When the lateral adjustment screw passes through the lateral through-groove and is penetrated into the adjustment block through the connecting hole, the pair of lateral adjustment nuts are respectively located on the outer sides of the side walls of the pair of monomers that are away from each other.

[0012] Furthermore, in the bidirectional locker of the present invention, a longitudinal adjustment screw hole is provided on the rear end wall of the adjustment portion, and the longitudinal screw adjustment mechanism is connected to the monomer through the longitudinal adjustment screw hole.

[0013] Furthermore, in the bidirectional locking device of the present invention, the longitudinal screw adjustment mechanism includes a longitudinal adjustment screw. When the longitudinal adjustment screw passes through the longitudinal adjustment screw hole, one end of the longitudinal adjustment screw can push the adjustment block to move in the longitudinal direction relative to the monomer by screwing the longitudinal adjustment screw.

[0014] Furthermore, in the bidirectional locking device of the present invention, a locking nut is screwed onto the longitudinal adjustment screw, and when the longitudinal adjustment screw passes through the longitudinal adjustment screw hole, the locking nut is located inside the adjustment portion.

[0015] The purpose of the present invention is also achieved through the following technical solution: a keel locking structure, including the above-mentioned two-way locker, and the connecting parts of the two-way locker are respectively connected to the keels.

[0016] The purpose of the present invention is also achieved through the following technical solution: a keel tightening system, including the above-mentioned keel locking structure.

DETAILED DESCRIPTION

[0026] The principle and spirit of the present invention will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are provided only to enable those skilled in the art to better understand and implement the present invention, and are not intended to limit the scope of the present invention in any way.

[0027] It should be noted that although the expressions "first", "second", etc. are used herein to describe different components of the embodiments of the present invention, the expressions "first", "second", etc. are only used to distinguish between different components, and do not indicate a specific order or importance. In fact, the expressions "first", "second", etc. can be used interchangeably.

[0028] The directional terms appearing in this article are uniformly defined. The directional term "longitudinal" refers to the direction extending along the keels on both sides of the wall, and "transverse" refers to the direction extending horizontally along the end surface of the wall and perpendicular to the surfaces on both sides of the wall.

[0029] like Figure 1-3 As shown, the bidirectional locking device of the present invention comprises a pair of monomers 1 arranged with a transverse interval, a pair of longitudinal screw adjustment mechanisms 3, a pair of adjustment blocks 4 and a transverse screw adjustment mechanism 2. Each monomer 1 is used in combination with a longitudinal screw adjustment mechanism 3 and an adjustment block 4 respectively, and a transverse screw adjustment mechanism 2 is used to connect a pair of monomers 1, thereby combining into a set of bidirectional locking devices.

[0030] In an embodiment of the present invention, each monomer 1 includes a connecting portion 11 and an adjusting portion 12 that are fixedly connected in the longitudinal direction. The connecting portion 11 and the adjusting portion 12 may be integrally formed or may be assembled after being processed separately. In this embodiment, the connecting portion 11 is a rectangular frame structure, and the rectangular frame includes two upper and lower parallel top walls, the top walls are rectangular, and pillars are welded at the four corners of the rectangle along the upper and lower directions. In the present invention, the wall structures away from the ground and close to the ground after the components are installed are both "top walls". Three connecting holes are respectively opened on the two top walls, and the spacing between the three connecting holes is the same. The ends of the connected keels 6 are provided with connecting holes that are aligned and locked therewith.

[0031] In the embodiment of the present invention, the adjustment part 12 is a rectangular frame structure, and the rectangular frame includes a pair of top walls arranged in parallel from top to bottom, a pair of side walls arranged in parallel from left to right, and a rear end wall perpendicular to the top wall and the side wall. A pair of top walls are respectively provided with longitudinal slide grooves 123, a pair of side walls are respectively provided with transverse through grooves 124, and a longitudinal adjustment screw hole 125 is provided on the rear end wall. The adjustment block 4 is arranged in the rectangular frame of the adjustment part 12, and a connecting hole 41 penetrating the adjustment block 4 is provided in the middle of the adjustment block 4. The upper and lower ends of the adjustment block 4 are respectively positioning parts, and the positioning parts are respectively embedded in the longitudinal slide groove 123, so that the slider 4 can move relative to the monomer 1 along the extension direction of the longitudinal slide groove 123, and the longitudinal slide groove 123 limits the slider 4 from moving relative to the monomer 1 along the transverse direction.

[0032] In this embodiment, the transverse screw adjustment mechanism 2 includes a transverse adjustment screw 21, a pair of transverse adjustment nuts 22 are screwed on the transverse adjustment screw 21, and a pair of transverse gaskets 23 are also arranged on the opposite sides of the pair of transverse adjustment nuts 22. The transverse adjustment screw 21 passes through the transverse through grooves 124 of the pair of adjustment parts 12 and the connecting holes 41 of the pair of connecting blocks 4, respectively, to achieve the connection between the transverse adjustment screw 21 and the adjustment block 4, thereby achieving the connection between the transverse adjustment screw 21 and the pair of monomers 1, and the transverse adjustment screw 21 can freely move in the transverse direction relative to the connecting hole 41. The pair of transverse adjustment nuts 22 and the transverse gasket 23 are respectively located on the outer sides of the side walls of the pair of monomers 1 that are away from each other. The distance between the pair of monomers 1 is manually adjusted, and the transverse gasket 23 is pressed against the side wall of the adjustment part 12 by screwing the transverse adjustment nut 22, so as to achieve the adjustment and locking of the distance between the pair of monomers 1.

[0033] In this embodiment, each longitudinal screw adjustment mechanism 3 includes a longitudinal adjustment screw 31, which is threadedly connected to the adjustment portion 12 through the longitudinal adjustment screw hole 125. By screwing the longitudinal adjustment screw 31, due to the action of the thread, the longitudinal adjustment screw 31 can move relative to the monomer 1 in the longitudinal direction, and one end of the longitudinal adjustment screw 31 can push the adjustment block 4 to move along the longitudinal slide groove 123, thereby driving the entire transverse screw adjustment mechanism 2 to move relative to the monomer 1 in the longitudinal direction. In this embodiment, a screw operating portion can be provided at the other end of the longitudinal adjustment screw 31 to facilitate manual or tool screwing of the longitudinal adjustment screw 31. In this embodiment, a locking nut 32 can be screwed on the portion of the longitudinal adjustment screw 31 that extends into the rectangular frame of the adjustment portion 12, thereby preventing the longitudinal adjustment screw 31 from being separated from the monomer 1 and avoiding the loss of parts during transportation.

[0034] In this embodiment, a longitudinal limiting boss is formed at the intersection of the adjusting portion 12 and the connecting portion 11, and the longitudinal limiting boss is composed of two upper and lower top longitudinal limiting bosses 121 and a side longitudinal limiting boss 122. The top longitudinal limiting boss 121 extends out of the connecting portion 11 from the upper and lower directions, and the side longitudinal limiting boss 122 extends out of the connecting portion 11 from the lateral direction, so that when the end of the keel is connected to the connecting portion 11, the longitudinal limiting boss is used to achieve longitudinal positioning of the keel. In this embodiment, the longitudinal limiting boss is a separately arranged protruding structure. In other embodiments, the rectangular frame cross-sectional projection profile of the adjusting portion 12 is larger than the rectangular frame of the connecting portion 11, and the larger portion directly constitutes the longitudinal limiting boss without the need to separately arrange a protruding structure. In this embodiment, the size of the longitudinal limiting boss extending out of the connecting portion 11 is the same as the cross-sectional wall thickness corresponding to the keel, so that after the keel is connected, the outer surface of the keel wall is flush with the height of the longitudinal limiting boss. Those skilled in the art will appreciate that the number of the top longitudinal limiting boss 121 may be one, and the number of the side longitudinal limiting bosses 122 may be two. In this embodiment, the number of the side longitudinal limiting bosses 122 is only one, and no longitudinal limiting boss is provided on the other side, so that when connected to a keel having an end cross-section with an open shape on one side, the outer surface of the side wall of the keel corresponding to the open side after connection is flush with the outer surface of the connecting portion 11. Since no side wall is provided at the opening, there is no need to additionally provide a longitudinal limiting boss for longitudinal limiting, which saves material costs, reduces the weight of the two-way locker, and facilitates transportation.

[0035] The following is a description of the process of installing and disassembling the building formwork system using the bidirectional locker of the present invention: after installing the building formwork according to the size of the free end of the shear wall to be cast, most of the keels are positioned around the secondary keels of the formwork along the two side surfaces of the wall, the spacing of a pair of monomers 1 is roughly adjusted to meet the spacing requirements of the keels 6 on both sides of the wall, and the last pair of keels 6 on the two side surfaces of the wall close to the free ends are installed and positioned so that the connecting holes at the ends of the keels 6 are aligned with the connecting holes on the connecting parts 11 of the pair of monomers 1. After being fixed and locked with connecting parts such as pins, the lateral adjustment nut 22 is screwed so that the front end gasket pushes the pair of monomers 1 to drive the pair of keels 6 to clamp the formwork 5, and the longitudinal adjustment screw 31 is screwed so that the end of the adjustment block 4 drives the lateral adjustment screw 21 to move toward the wall end formwork. After the lateral adjustment screw 21 presses the wall end formwork, the longitudinal adjustment screw 31 is continued to be screwed so that the monomer 1 pulls the keels on both sides of the wall away from the wall end formwork, thereby realizing the locking of the entire keel clamping system on both sides of the wall and the wall end surface.

[0036] The foregoing description of the implementation of the present invention has been given for purposes of illustration and description. The foregoing description is not intended to be exhaustive nor to limit the invention to the exact form disclosed, and various variations and modifications are possible in accordance with the above teachings or may be obtained from the practice of the invention. These embodiments are selected and described in order to illustrate the principles of the invention and its practical application, so that those skilled in the art can utilize the invention in various embodiments and with various modifications suitable for the particular use contemplated.
