Description

Technical Field

[0001] This utility model belongs to the technical field of concrete pouring formwork clamps, specifically relating to a strip concrete foundation formwork installation clamp. Background Technology

[0002] When installing and fixing existing strip concrete foundation formwork, common methods include: ① using uprights inserted into the foundation or fixed to pre-embedded reinforcing bars, binding horizontal steel pipes with top fasteners for positioning, and fixing with external diagonal bracing; ② external support and internal support, with reinforcing bars for positioning; ③ brick formwork, soil formwork, etc. While these methods can meet the requirements of fixing and sturdiness, they are inconvenient to install, involve complex procedures, are difficult to reuse, and are challenging to control in terms of installation accuracy. They are also unsuitable for installing strip foundation formwork with the same or similar cross-sections. Utility Model Content

[0003] The purpose of this utility model is to provide a clamping device for installing strip concrete foundation formwork. This device has good practicality, simple structure, and convenient installation. It is suitable for positioning, installing and reinforcing strip foundation concrete formwork in various environments on construction sites.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A strip concrete foundation formwork installation clamping fixture, the installation clamping fixture includes a first clamping side plate, a second clamping side plate, an inner limiting tube, a threaded rod and a locking nut;

[0006] The first clamping side plate includes a first clamping side plate body and a telescopic inner tube that intersect at right angles, and the second clamping side plate includes a second clamping side plate body and a telescopic outer tube that intersect at right angles, with the telescopic inner tube inserted into the telescopic outer tube;

[0007] Through holes are provided at relative positions on the first and second clamping side plates, and both ends of the lead screw pass through the through holes and are fixed with lock nuts.

[0008] The inner limiting tube is inserted through the lead screw.

[0009] Preferably, anti-slip pads are provided on the inner surfaces of the first and second clamping side plates. These anti-slip pads prevent the clamping side plates from sliding when clamped and fixed with the base template.

[0010] Preferably, the telescopic inner tube is provided with several spring pins, and the telescopic outer tube is provided with several corresponding pin fixing holes. The different lengths of the telescopic inner tube within the telescopic outer tube allow adjustment of the width between the two foundation templates, thereby adjusting the width of the poured concrete wall.

[0011] Preferably, the locking nut is provided with a rotating handle. This rotating handle facilitates the adjustment of the position of the locking nut at both ends of the lead screw, making locking and loosening more convenient.

[0012] Preferably, limiting plates are provided at both ends of the inner limiting tube. These limiting plates increase the contact area between the inner limiting tube and the base template, enhancing the tightness of the connection between them.

[0013] Preferably, the limiting plate is square or circular.

[0014] Preferably, the first clamping side plate and the telescopic inner tube are connected by a hinge; the second clamping side plate and the telescopic outer tube are connected by a hinge.

[0025] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0026] Example 1

[0027] like Figure 1 and Figure 3 As shown, a strip concrete foundation formwork installation clamping fixture includes a first clamping side plate 1, a second clamping side plate 2, an inner limiting tube 3, a screw rod 4, and a locking nut 5.

[0028] like Figure 4-5 As shown, the first clamping side plate 1 includes a first clamping side plate body 1-1 and a telescopic inner tube 1-2 intersecting at right angles, and the second clamping side plate 2 includes a second clamping side plate body 2-1 and a telescopic outer tube 2-2 intersecting at right angles. The telescopic inner tube 1-2 is inserted into the telescopic outer tube 2-2. Optionally, a plurality of spring pins are provided on the telescopic inner tube 1-2, and a plurality of pin fixing holes are correspondingly provided on the telescopic outer tube 2-2. After the telescopic inner tube is inserted into the telescopic outer tube, the two can be fixed together by spring pins.

[0029] like Figure 2 As shown, through holes are provided at relative positions on the first clamping side plate 1 and the second clamping side plate 2. The two ends of the lead screw 4 pass through the through holes and are fixed by locking nuts 5. By adjusting the locking nuts 5, the template clamp shrinks and tightens, making the basic template 6, the clamping side plate and the inner limiting tube 3 firmly locked together.

[0030] The inner limiting tube 3 is threaded onto the lead screw 4. The lead screw 4 passes horizontally through the locking clamp, and its position can be adjusted according to actual conditions. The locking nut can rotate on the lead screw. The inner limiting tube is fitted onto the lead screw, limiting and controlling the width between two opposing foundation templates 6. Different lengths of inner limiting tubes can be used to fix foundation templates of different widths.

[0031] Anti-slip pads 8 are provided on the inner surfaces of the first clamping side plate 1 and the second clamping side plate 2.

[0032] A rotating handle is provided on the locking nut 5. Twisting the rotating handle moves the locking nut on the lead screw, thereby fixing the inner limiting tube and the base template. Limiting plates are provided at both ends of the inner limiting tube 3. Figure 6 As shown, the limiting plate is square, and the hole on the square limiting plate is for the lead screw to pass through. It can also be selected as round if needed.

[0033] The first clamping side plate 1-1 and the telescopic inner tube 1-2 are hinged together; the second clamping side plate 2-1 and the telescopic outer tube 2-2 are also hinged together. The length and height of the first and second clamping side plates can be adjusted according to the actual site conditions.

[0034] This utility model is applicable to the installation of formwork for various smaller-sized strip foundations and frame beam concrete foundations on the foundation pad 7. During construction, square timber or square steel pipes are used to make the first and second clamping side plates. The strip concrete foundation formwork or frame beam formwork is fixed by the inner limiting tube, threaded rod, and locking nut. After the formwork is fixed, concrete is poured. After the clamps are removed, the formwork will not twist, deform, or shift, and the concrete will have a beautiful appearance. Moreover, the structure of the clamp is relatively simple.

[0035] In practice, anchor bolts can be installed at the bottom of the first and second clamping side plates, or steel bars can be inserted into the first and second clamping side plates to fix them to the foundation template, thereby increasing the connection between the foundation template and the clamp. The size of the clamp can also be adjusted according to the actual situation.

[0036] For any content not described in detail in this utility model, conventional technical knowledge in the field can be used.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
