Description

Technical Field

[0001] The utility model relates to the technical field of building engineering supports, and specifically relates to a fixing support for building engineering. Background Art

[0002] The socketed support is a support widely used in the fields of high formwork, large span, and heavy support projects. It mainly consists of vertical poles, horizontal bars, diagonal bars, and joints, etc. Among them, the joint part adopts socketed connection;

[0003] Among them, the vertical pole is a steel pipe of a certain length with multiple socket plates welded evenly on it (the distance between two socket plates is generally 0.5m). The horizontal bar is formed by welding calipers with pins at both ends of the steel pipe. During assembly, the horizontal bar is clamped outside the socket plate by the caliper, and then the pin passes through the socket groove on the socket plate. The overall assembly operation is simple and convenient.

[0004] In actual building construction, the operation of engineering equipment will generate vibrations, and these vibrations will be transmitted to the fixing support. Frequent vibrations will cause the pins to become loose. In order to prevent the loose pins from detaching from the socket plate, a fixing support for building engineering is provided. Content of the Utility Model

[0005] The purpose of the utility model is to provide a fixing support for building engineering in order to achieve the purpose of preventing loose pins from detaching from the socket plate.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A fixing support for building engineering, including a support assembly composed of a column, a socket plate, a horizontal bar, and a C-shaped caliper. The socket plate is welded and fixed on the outside of the column. A plurality of socket grooves are opened at the top of the socket plate, which are circumferentially distributed and penetrate through the bottom of the socket plate. The C-shaped caliper is fixedly welded at both ends of the horizontal bar. The horizontal bar is spliced with the column by clamping the C-shaped caliper outside the socket plate. At the top and bottom of the upper protrusion of the C-shaped caliper, an upper through groove and a limit groove are respectively opened, and the upper through groove and the limit groove are communicated with each other. A lower through groove penetrating through the upper and lower ends is opened on the lower protrusion of the C-shaped caliper. An insert pin assembly is arranged inside the upper through groove and the limit groove. The insert pin assembly sequentially penetrates through the socket groove and the lower through groove and is closely attached to the inner wall of the socket groove to realize the connection and fixation between the horizontal bar and the column;

[0007] The insert pin assembly includes a trapezoidal insert pin, an arc-shaped storage groove, a limit retaining piece, and an I-shaped clamping post;

[0008] The trapezoidal insert pin sequentially penetrates through the upper through groove, the limit groove, the socket groove, and the lower through groove from above the C-shaped caliper to below the C-shaped caliper. The arc-shaped storage groove is opened at the bottom of one side of the trapezoidal insert pin, and the limit retaining piece is stored inside the arc-shaped storage groove;

[0009] The I-shaped clamping column passes through the trapezoidal latch pin and both ends of the limit stopper, and is used to provide support for the rotation of the limit stopper;

[0010] After the limit baffle moves down to the bottom of the C-shaped caliper, it rotates to a horizontal state with the I-shaped clamping column as the center. The limit baffle in the horizontal state cannot pass through the lower through groove, so as to limit the upward movement of the trapezoidal latch.

[0011] As a further solution of the utility model: the latch assembly further includes an arc-shaped opening groove and a raised round block;

[0012] The arc-shaped opening groove is opened on one side of the inner wall of the arc-shaped receiving groove and penetrates to the other side of the trapezoidal latch; the raised round blocks are fixed on both sides of the outer wall of the limit blocking piece at positions close to the top, and one raised round block penetrates the arc-shaped opening groove to the other side of the trapezoidal latch;

[0013] The raised round block makes it easy for a worker to apply a thrust to the limit blocking piece so that the limit blocking piece is deflected to a horizontal state.

[0014] As a further solution of the utility model: the length of the upper through-groove is less than the maximum length of the top of the trapezoidal latch, the width of the upper through-groove is greater than the width of the raised round block and less than the width of the I-shaped clamping column, and the width of the buckle groove, the limiting groove, and the lower through-groove is greater than the width of the I-shaped clamping column;

[0015] The length of the limit blocking piece in a horizontal state is greater than the length of the lower through slot.

[0016] As a further solution of the utility model: the arc-shaped receiving groove and the arc-shaped opening groove penetrate one end of the trapezoidal latch pin, and the arc-shaped receiving groove and the arc-shaped opening groove match the rotation trajectory of the limit stopper and the raised round block respectively;

[0017] A rubber layer is adhered to the side walls of the limit blocking piece and the arc-shaped receiving groove that are close to each other.

[0018] As a further solution of the utility model: the trapezoidal latch, arc-shaped receiving groove, and arc-shaped opening groove are integrally formed by a stamping process, the limit baffle and I-shaped clamping column are formed by a metal hydraulic casting process, and the I-shaped clamping column is connected and formed with the trapezoidal latch and the limit baffle by a riveting process.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] By setting up the latch assembly, when the trapezoidal latch becomes loose and vibrates upward due to external vibration, the horizontal limit baffle will be restricted and unable to pass through the lower through groove, thereby preventing the trapezoidal latch from detaching from the buckle plate. This can further ensure that the connection between the cross bar and the column is not loose, thereby improving the safety of the bracket assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1 to 3 , in the embodiment of the present utility model, a fixing bracket for construction engineering includes a bracket assembly 1 composed of a column 101, a buckle plate 102, a cross bar 104, and a C-shaped caliper 105. The buckle plate 102 is welded and fixed to the outside of the column 101. A plurality of buckle grooves 103 that are circumferentially distributed and penetrate the bottom of the buckle plate 102 are provided at the top of the buckle plate 102. The C-shaped caliper 105 is fixedly welded to both ends of the cross bar 104. The cross bar 104 is spliced with the column 101 by being clamped to the outside of the buckle plate 102 through the C-shaped caliper 105. The top and bottom of the upper protrusion of the C-shaped caliper 105 are respectively provided with an upper through groove 106 and a limit groove 107, and the upper through groove 106 and the limit groove 107 communicate with each other. The lower protrusion of the C-shaped caliper 105 is provided with a lower through groove 108 that penetrates its upper and lower ends. An insertion pin assembly 2 is arranged inside the upper through groove 106 and the limit groove 107. The insertion pin assembly 2 sequentially penetrates the buckle groove 103 and the lower through groove 108 and is in close fit with the inner wall of the buckle groove 103 to realize the connection and fixation of the cross bar 104 and the column 101;

[0027] The insertion pin assembly 2 includes a trapezoidal pin 201, an arc-shaped receiving groove 202, a limit retaining piece 204, and an I-shaped clamping post 205;

[0028] The trapezoidal pin 201 sequentially penetrates through the upper through slot 106, the limiting groove 107, the buckling groove 103, and the lower through slot 108 from above the C-shaped caliper 105 to the lower side of the C-shaped caliper 105. The arc-shaped storage groove 202 is opened at the bottom of one side of the trapezoidal pin 201, and the limiting flap 204 is stored inside the arc-shaped storage groove 202.

[0029] The I-shaped clamping post 205 penetrates through both ends of the trapezoidal pin 201 and the limiting flap 204 to provide support for the rotation of the limiting flap 204.

[0030] After the limiting flap 204 moves down to the lower side of the C-shaped caliper 105, it rotates to a horizontal state with the I-shaped clamping post 205 as the center. The horizontal limiting flap 204 cannot pass through the lower through slot 108, which is used to realize the upward limit of the trapezoidal pin 201.

[0031] The pin assembly 2 further includes an arc-shaped opening groove 203 and a convex round block 206.

[0032] The arc-shaped opening groove 203 is opened on one side of the inner wall of the arc-shaped storage groove 202 and penetrates to the other side outside the trapezoidal pin 201. The convex round blocks 206 are fixed at positions near the top on both outer walls of the limiting flap 204, and one convex round block 206 penetrates through the arc-shaped opening groove 203 to the other side of the trapezoidal pin 201.

[0033] The convex round blocks 206 facilitate the staff to apply a thrust to the limiting flap 204 to deflect the limiting flap 204 to a horizontal state.

[0034] The trapezoidal pin 201, the arc-shaped storage groove 202, and the arc-shaped opening groove 203 are integrally formed by stamping. The limiting flap 204 and the I-shaped clamping post 205 are formed by metal hydraulic casting. The I-shaped clamping post 205 is connected to the trapezoidal pin 201 and the limiting flap 204 by riveting and formed.

[0035] In this embodiment: When assembling the cross bar 104 and the column 101, the operation steps are as follows:

[0036] The C-shaped caliper 105 is clamped outside the buckle plate 102 (it should be noted that at this time, the trapezoidal pin 201 is in an upward state, the limiting flap 204 is stored inside the arc-shaped storage groove 202, and its I-shaped clamping post 205 is limited and stored inside the limiting groove 107), and the upper through slot 106 and the lower through slot 108 on the C-shaped caliper 105 are aligned with the buckling groove 103. At this time, the trapezoidal pin 201 will move through the buckling groove 103 and the lower through slot 108 under its own gravity.

[0037] Afterwards, an external tool can be used to eccentrically push the raised round block 206, causing the limit retaining piece 204 to deflect under force. The limit retaining piece 204 rotates around the I-shaped clamping post 205 (it should be noted that the cross-section of the I-shaped clamping post 205 is in the shape of an inverted "I", and a hole groove for rotational connection with the middle part of the I-shaped clamping post 205 is provided on the limit retaining piece 204). The limit retaining piece 204 finally rotates to a horizontal state, and at this time, the preliminary connection between the cross bar 104 and the upright post 101 is completed;

[0038] Finally, an external tool is used to hammer downwards on the top of the trapezoidal pin 201, causing the trapezoidal pin 201 to move downwards and closely fit against the inner wall of the fastening groove 103, thus realizing the firm connection between the cross bar 104 and the upright post 101;

[0039] Through the above structural settings, when the trapezoidal pin 201 loosens and vibrates upwards due to external vibration, the horizontal limit retaining piece 204 will be restricted and unable to pass through the lower through groove 108, thereby preventing the trapezoidal pin 201 from detaching from the fastening plate 102. This can further ensure that the connection between the cross bar 104 and the upright post 101 does not become loose and improve the use safety of the support assembly 1;

[0040] When it is necessary to disassemble the support assembly 1, only need to first rotate and store the limit retaining piece 204 into the arc-shaped storage groove 202, and then tap the bottom of the trapezoidal pin 201 upwards to separate the trapezoidal pin 201 from the fastening groove 103. Its operation method is the same as the traditional disassembly operation.

[0041] Please refer specifically to Figures 1 to 3 , the length of the upper through groove 106 is less than the maximum length of the top of the trapezoidal pin 201, the width of the upper through groove 106 is greater than the width of the raised round block 206 and less than the width of the I-shaped clamping post 205, and the widths of the fastening groove 103, the limit groove 107, and the lower through groove 108 are greater than the width of the I-shaped clamping post 205;

[0042] The length of the horizontal limit retaining piece 204 is greater than the length of the lower through groove 108;

[0043] The arc-shaped storage groove 202 and the arc-shaped opening groove 203 penetrate one end of the trapezoidal pin 201, and the arc-shaped storage groove 202 and the arc-shaped opening groove 203 respectively match the rotation trajectories of the limit retaining piece 204 and the raised round block 206;

[0044] A rubber layer is adhered to the side walls of the limit retaining piece 204 and the arc-shaped storage groove 202 that are close to each other.

[0045] In this embodiment: through the above structure, the convex circular block 206 can pass through the upper through groove 106, the buckling groove 103, the limiting groove 107, and the lower through groove 108. The I-shaped clamping post 205 can only pass through the buckling groove 103, the limiting groove 107, and the lower through groove 108 and cannot pass through the upper through groove 106. In this way, the pin assembly 2 can be prevented from detaching from the C-shaped caliper while ensuring smooth use.

[0046] Through the arrangement of the limiting flap 204 and the rubber layer on the side of the arc-shaped receiving groove 202, it is used to increase the mutual friction between the limiting flap 204 and the arc-shaped receiving groove 202, so as to ensure the stability of the limiting flap 204 in the received state and the horizontal state.

[0047] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
