Description

Technical Field

[0001] This utility model relates to the field of template fixing technology, and in particular to a modular fixing device for foundation pouring. Background Technology

[0002] Foundation pouring, as a core component of civil engineering, directly impacts the load-bearing capacity, seismic resistance, and durability of building structures. During foundation construction, the stability of the formwork system is crucial for ensuring the precision of concrete forming. Traditional formwork fixing methods primarily rely on fasteners and clamps to mechanically compress and secure adjacent formwork (such as bolt tightening or metal clamp locking). However, this method suffers from the following technical bottlenecks:

[0003] Low installation efficiency and poor adaptability: Existing devices require multiple steps to adjust the clamp positions and tighten them point by point during installation. Especially in complex geological conditions (such as collapsible loess and soft soil areas) or low-temperature environments, construction efficiency is significantly reduced, making it difficult to meet the demands of rapid construction. Lack of precise control mechanisms: Some connectors require point-by-point tightening or disassembly, limiting construction efficiency; metal parts are prone to wear or deformation during repeated hammering or forceful tightening, affecting locking reliability; existing tightening methods rely heavily on manual experience to judge the degree of tightening, which can lead to uneven local stress or insecure fixing if not operated properly. Therefore, a modular fixing device for foundation pouring is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a modular fixing device for foundation pouring, so as to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of the present invention provides a modular fixing device for foundation pouring, including a first clip and a second clip, both the first clip and the second clip being bent, the first clip being hollow, and the hollow part of the first clip being movably connected to the second clip;

[0007] The first card has a first through hole, and the second card has a second through hole, the length of the second through hole being less than the length of the first through hole;

[0008] The inner sides of the ends of the first and second clips are fixedly connected with protrusions that adapt to the grooves of the template columns;

[0009] A pin is inserted into the first and second through holes, and the pin is wedge-shaped.

[0010] The top of the pin is fixedly connected to an end head, and a slot is formed on the outer surface of the pin;

[0011] The bottom of the first card is fixedly connected to a connector, and the bottom of the connector is fixedly connected to a card head. The end of the card head is tilted upward and the end of the card head is inserted into a card slot.

[0012] Preferably, the first and second clips are made of stainless steel and are both right-angled.

[0013] The above technical solution is adopted: this device is modular and assembled.

[0014] This device consists of three parts. The first part is the first clip, which is hollow. The hollow part is movably connected to the second clip. A connector is fixedly connected to the bottom of the first clip, and a flexible clip head is fixedly connected to the bottom of the connector.

[0015] The second part is the second card, which is thinner than the first card, and the second perforation of the second card is shorter than the first perforation of the first card.

[0016] The third part is the pin, which has a head at the top and a slot on its outer surface.

[0017] Preferably, in any of the above solutions, the thickness of the first card is greater than the thickness of the second card, and the first and second through holes are aligned vertically.

[0018] When this device is in operation, the second clip is inserted into the first clip. The inner sides of the ends of the first and second clips are fixedly connected with protrusions that fit the grooves of the template columns to hook onto the template columns. The pins are inserted along the first and second through holes. The ends are struck with a hammer, and the pins continue to be inserted, causing the first and second clips to come together and directly hold the two template columns tightly, thereby fixing and locking the adjacent template columns. This achieves modular fixing, which is secure and easy to dismantle.

[0019] After the pin is fully inserted, a slot is cut into the pin surface. The bottom of the first locking component securely connects to the connector and the locking head. The end of the locking head can engage with the slot. A sound or vibration feedback indicates that the locking head has been properly secured, preventing excessive hammering and thus avoiding component deformation or excessive installation stress caused by blind hammering.

[0020] Preferably, in any of the above solutions, the pin is welded to the end, and the width of the pin decreases from top to bottom.

[0021] Device Structure: Main Support Structure (First Clamping Component): A right-angled hollow frame made of stainless steel, with a large thickness to ensure rigidity; its inner cavity accommodates the second clamping component. A long, narrow first through-hole, approximately 50-80mm in length, is opened at the top. The bottom is fixed to the connecting joint with screws; the end of the joint has an upward-curving elastic clamp. The inner side of the end is welded with a protrusion integrally formed to fit the pre-reserved groove of the template column.

[0022] Sliding locking structure (second clamp): A right-angled frame made of stainless steel, thinner than the first clamp to facilitate sliding. It partially inserts into the hollow cavity of the first clamp to achieve a movable connection, with the sliding direction perpendicular to the template column axis. A short, strip-shaped second through hole is provided at the top. The inner side of the end is welded and integrally formed with a protrusion that adapts to the pre-reserved groove of the template column.

[0023] The pin is a wedge-shaped metal part, with its width decreasing from top to bottom. A welded end cap increases the hammering contact area. A groove, approximately 1-2 mm deep, is machined into the center of the outer surface. The pin passes through the first and second through holes, with its wedge-shaped surface forming a beveled fit against the inner wall of the through holes.

[0024] Preferably, in any of the above embodiments, the connector is connected to the first clamp by screws, and the clamp head is elastic.

[0025] Preferably, the material of the card head is plastic, as described in any of the above solutions.

[0026] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0027] This modular fixing device for foundation pouring involves inserting a second clip into a first clip. The inner ends of both the first and second clips are fixedly connected with protrusions that fit the grooves of the template columns, allowing them to hook onto the template columns. A pin is inserted through the first and second through holes, and the end is struck with a hammer. The pin continues to be inserted, causing the first and second clips to come together and directly hold the two template columns, thus fixing and locking adjacent template columns. This modular fixing method ensures a secure and reliable fixation, while also simplifying subsequent disassembly.

[0028] After the pin is fully inserted, a slot is cut into the pin surface. The bottom of the first locking component securely connects to the connector and the locking head. The end of the locking head can engage with the slot. A sound or vibration feedback indicates that the locking head has been properly secured, preventing excessive hammering and thus avoiding component deformation or excessive installation stress caused by blind hammering.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] like Figure 1-4 As shown, the modular fixing device for foundation pouring includes a first clip 1 and a second clip 2. Both the first clip 1 and the second clip 2 are bent. The first clip 1 is hollow, and the hollow part of the first clip 1 is movably connected to the second clip 2. The first clip 1 is directly sleeved on the second clip 2, and a part of the second clip 2 is inserted into the hollow part of the first clip 1.

[0039] The first card 1 has a first through hole 3, and the second card 2 has a second through hole 4. The length of the second through hole 4 is less than the length of the first through hole 3.

[0040] The inner sides of the ends of the first clip 1 and the second clip 2 are fixedly connected with protrusions that are adapted to the grooves of the template column;

[0041] A pin 5 is inserted into the first through hole 3 and the second through hole 4. The pin 5 is wedge-shaped.

[0042] The top of the pin 5 is fixedly connected to the end head 6, and a slot 7 is opened on the outer surface of the pin 5;

[0043] The bottom of the first clip 1 is fixedly connected to a connector 8, and the bottom of the connector 8 is fixedly connected to a clip head 9. The end of the clip head 9 is raised upward and the end of the clip head 9 is inserted into the clip groove 7.

[0044] Example 1: The first clip 1 and the second clip 2 are made of stainless steel, and both are right-angled. The thickness of the first clip 1 is greater than that of the second clip 2. The first through hole 3 and the second through hole 4 are aligned vertically. The pin 5 is welded to the end 6, and the width of the pin 5 decreases from top to bottom. The connector 8 is connected to the first clip 1 by screws, and the clip head 9 is elastic. The clip head 9 is made of plastic.

[0045] Example 2: This device is modular and assembled.

[0046] This device consists of three parts. The first part is the first clip 1, which is hollow. The hollow part is movably connected to the second clip 2. The lower part of the first clip 1 is fixedly connected to the connector 8, and the bottom of the connector 8 is fixedly connected to an elastic clip 9.

[0047] The second part is the second card 2, which is thinner than the first card 1, and the second perforation 4 of the second card 2 is shorter than the first perforation 3 of the first card 1.

[0048] The third part is the pin 5, which has an end head 6 at its top and a slot 7 on its outer surface. The device structure consists of: the main load-bearing structure (first clamping component 1): a right-angled hollow frame made of stainless steel with a large thickness to ensure rigidity; its inner cavity accommodates the second clamping component 2. A long, narrow first through hole 3, approximately 50-80mm in length, is opened at the top. The bottom is fixed to the connector 8 with screws; the end of the connector 8 has an upward-curving elastic clamping head 9. A protrusion 11, integrally formed and welded to the inner side of the end, adapts to the pre-reserved slot of the template column.

[0049] Sliding locking structure (second clamp 2): A right-angled frame made of stainless steel, thinner than the first clamp 1 to facilitate sliding. Partially inserted into the hollow cavity of the first clamp 1 for a movable connection, with the sliding direction perpendicular to the template column axis. A short, strip-shaped second through hole 4 is provided at the top. The inner side of the end is welded and integrally formed with a protrusion adapted to the pre-reserved groove of the template column.

[0050] Pin 5 is a wedge-shaped metal part whose width decreases from top to bottom. A welded end 6 is attached to the top to increase the hammering contact surface. A groove 7, approximately 1-2 mm deep, is machined in the middle of the outer surface. Pin 5 passes through the first through hole 3 and the second through hole 4, and its wedge surface forms a beveled fit with the inner wall of the through hole.

[0051] The working principle of this utility model is as follows:

[0052] Preliminary positioning: The device is straddled on two adjacent template columns, so that the protrusion 11 at the end of the first clamp 1 and the protrusion 12 at the end of the second clamp 2 respectively engage in the reserved grooves on the side of the corresponding template column.

[0053] Locking by tapping: Align the pin 5 with the first through hole 3 and the second through hole 4, and insert it vertically. Tap the end 6; the pin 5 will move downwards. Because the pin 5 is wedge-shaped and the second through hole 4 is relatively short, as the pin 5 moves downwards:

[0054] By squeezing the inner wall of the second perforation 4 with a wedge, the second locking piece 2 is forced to slide further into the first locking piece 1.

[0055] At the same time, the interaction between the wedge surface and the inner wall of the first perforation 3 drives the first card 1 to produce a slight reverse displacement.

[0056] The two clamps move toward each other, causing the protrusions 11 and 12 at their ends to tighten within the pre-reserved groove of the template column, thereby rigidly clamping the adjacent template column.

[0057] Feedback and self-locking (key innovation): When the pin 5 continues to move down to the preset locking position (i.e., the two template columns are fully clamped): the groove 7 on the outer surface of the pin 5 moves to the position aligned with the raised end of the clip 9. At this time, the elastic clip 9, which was previously bent by the main body of the pin 5, is quickly released due to its own rebound force, and its end pops into the groove 7 with a "click".

[0058] The action is accompanied by a clearly perceptible vibration and sound, clearly indicating to the worker that the lock is in place and that the hammering should be stopped immediately.

[0059] The engagement of the clamp head 9 and the clamp slot 7 forms a mechanical interlock, effectively preventing the pin 5 from accidentally retracting and loosening under pouring vibration or external impact.

[0060] Compared with the prior art, the present invention has the following advantages:

[0061] This modular fixing device for foundation pouring has a second clip 2 inserted into a first clip 1. The inner sides of the ends of the first clip 1 and the second clip 2 are fixedly connected with protrusions that fit the grooves of the template columns to hook onto the template columns. The pin 5 is inserted through the first through hole 3 and the second through hole 4. The end 6 is struck with a hammer, and the pin 5 continues to be inserted, causing the first clip 1 and the second clip 2 to come together and directly hug the two template columns, thereby fixing and locking the adjacent template columns. This modular fixing is reliable and easy to dismantle later.

[0062] After the pin 5 is fully inserted, a slot 7 is formed on the surface of the pin 5. The bottom of the first locking component 1 is fixedly connected to the connector 8 and the locking head 9. The end of the locking head 9 can be inserted into the slot 7. When the locking head 9 is inserted into the slot 7, there is an audible or vibratory feedback indicating to the technician that it has been properly locked in place. This avoids excessive hammering and prevents component deformation or excessive installation stress caused by blind hammering.
