Technical Field

[0001] The invention belongs to the technical field of curtain wall construction, and in particular relates to a limiting tool for installing curtain wall embedded parts. Background Art

[0002] With the rapid development of the construction industry, curtain walls are widely used in high-rise residential buildings, office buildings and other buildings. Curtain walls refer to the building's external protective structure or decorative structure that has a certain displacement capacity relative to the main structure and does not share the force on the main structure. As a beautiful and novel method of building wall decoration, glass curtain walls have also become a prominent feature of the modernist high-rise building era. Curtain wall embedded parts generally include embedded steel plates and anchor bars, which are pre-installed in the beam structure and used to connect the curtain wall with the main body in the later stage. The construction quality directly affects the overall construction of the curtain wall. The installation accuracy requirements are high, mainly including flatness, verticality and horizontality. The traditional construction method mainly uses manual positioning and construction by "leaning" and "hanging", which is time-consuming and labor-intensive, and the efficiency is very low, which affects the progress of the construction period. Although there are applications of embedded part limit devices in the prior art, most of these limit devices are fixed structures and cannot be adjusted according to needs. They have poor adaptability, causing many inconveniences in use. Therefore, it is necessary to improve the existing embedded part limit devices. Summary of the invention

[0003] In view of this, the invention aims to overcome the defects in the prior art and proposes a limiting tool for installing curtain wall embedded parts.

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] A limiting tool for installing curtain wall embedded parts, such as Figures 1 to 6 As shown, it includes at least two groups of limit units arranged side by side, each group of limit units is connected by a mounting rod, and the position of the limit unit on the mounting rod is adjusted by sliding to change the distance between the limit units, and the mounting rod includes a front mounting rod 1 and a rear mounting rod 2 arranged in parallel; the limit unit includes a crossbeam 3, a front clamping arm 4 is installed on one side of the crossbeam through the front mounting rod, and a rear clamping arm 5 is installed on the other side of the crossbeam through the rear mounting rod.

[0027] The front clamp arm includes a front working surface 15 and a rear working surface 16, and a front arm fixing hole 6 is provided in the middle of the front clamp arm; the rear clamp arm includes a transverse portion 7 and a vertical portion 8, and a plurality of rear arm fixing holes 9 are provided at intervals on the transverse portion; a front arm mounting groove 10 is provided at the end surface of the crossbeam corresponding to one end of the front clamp arm, and a rear arm mounting groove 11 is provided at the lower end surface corresponding to one end of the rear clamp arm, and the lower edge of the transverse portion is higher than the lower end surface of the crossbeam. A clamping limit space is formed between the vertical portion and the front clamp arm (the working surface facing the rear clamp arm). Figure 1 As shown, it is a schematic diagram of the present invention when the front working surface of the front clamp arm faces the rear clamp arm. Figure 6 As shown, it is a schematic diagram of the invention in which the rear working surface of the front clamping arm faces the rear clamping arm. It can be adjusted and used as needed according to actual use requirements, so that the tooling has strong adaptability and good versatility.

[0028] The crossbeam is provided with a forearm mounting hole 12 matching the front clamp arm fixing hole, and a plurality of rear arm mounting holes 13 matching the rear arm fixing holes are provided at intervals. The front and rear arm mounting holes are all through the crossbeam, so that the mounting rod can pass through each limiting unit to play a connecting role, and the limiting unit can slide on the mounting rod to adjust the position, which has better adaptability. The forearm mounting hole corresponds to the forearm mounting slot arrangement, and the rear arm mounting hole corresponds to the rear arm mounting slot arrangement.

[0029] The vertical part of the rear clamp arm in each limiting unit is slidably matched with an auxiliary installation rod 14, and the auxiliary installation rod is parallel to the rear installation rod. The auxiliary installation rod also serves to connect the limiting units, and can connect the rear clamp arms of each limiting unit in series, so that the rear clamp arm structure is more stable and the positioning is more accurate. When used, the vertical part of the rear clamp arm is attached to the embedded steel plate to limit the position, which improves the situation that the embedded steel plate is offset and convex during pouring. After the concrete is poured, the displacement deviation of the embedded parts is small, the apparent molding quality is good, and the construction can be carried out simultaneously with the main construction, which speeds up the embedding speed of the embedded parts.

[0030] The cross section of the auxiliary mounting rod is rectangular or circular. The cross section of the front mounting rod is rectangular, and the cross section of the rear mounting rod is rectangular. A fixing effect can be achieved by a rod, and only the front clamping arm and the rear clamping arm are allowed to move and adjust in the length direction of the rod without offset or rotation.

[0031] Usually, the length of the transverse portion is less than the length of the crossbeam. The transverse portion is provided with 3-5 rear arm fixing holes. The crossbeam is provided with 1-5 rear arm fixing holes. In an optional embodiment, the front working surface of the front clamping arm is provided with a vertical portion 19 and a first slope inclined portion 20 on the upper and lower sides, respectively, and the rear working surface is provided with a second slope inclined portion 17 and a third slope inclined portion 18 on the upper and lower sides. Arranging different parts of the front clamping arm corresponding to the rear clamping arm and fixing them through the front mounting rod can adapt to the application needs of different working conditions and have better versatility.

[0032] The invention has a reasonable structural design. When used, the vertical part of the rear clamp arm is limited by the embedded steel plate, and the clamping limit space formed between the vertical part and the front clamp arm clamps the upper part of the steel frame of the column beam structure. The front clamp arm has two front and rear working surfaces, and the corresponding working surface can be freely selected to match the steel frame of the beam structure according to needs, and the installation position of the rear clamp arm on the crossbeam can be adjusted according to needs, so that the clamping limit space can be adaptively adjusted to ensure that the tool is firmly fixed and the stability is guaranteed during the application process. In addition, the distance between the limit units can be adaptively adjusted according to needs, which makes the tool more adaptable and more versatile.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
