[0002] With the demand for environmental protection and high-quality development, prefabricated buildings have gradually emerged. Compared with traditional construction systems, prefabricated building construction systems have the characteristics of high efficiency, high precision, more material saving and environmental protection.

[0003] In the existing PCTF system, the composite exterior wall adopts a system of prefabricated outer leaf wall and cast-in-place inner wall. Therefore, when the inner concrete is poured, the bolt holes required for the formwork are already reserved in the outer leaf wall panel. Figure 4 As shown, the internal formwork needs to be reinforced with steel pipes, mountain clips 100' and screws 200'. During the installation of the inner formwork, the horizontal heights of the tension screw holes are consistent when the formwork at the inner corners of two adjacent wall panels are installed, resulting in a conflict in the horizontal positions of the screws at the inner corners of adjacent wall panels, and the tension screws cannot be installed.

[0004] In view of the problem in the prior art that the horizontal positions of the tie screws at the inner corners of two adjacent wall panels conflict, resulting in the inability to install the tie screws and affecting the installation of the inner formwork, technical personnel in this field have been looking for solutions.

[0037] The following is a detailed description of the clamping member and tie screw provided by the present invention, combined with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are highly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0038] Please refer to Figures 1a to 4 The clamping member 100 includes: a connecting member 1 and an accessory 2 detachably connected to the connecting member 1, the accessory 2 includes: two first clips 21 and two second clips 22; wherein, the connecting member 1 is provided with a first threaded hole 11 and two second threaded holes 12, the first threaded hole 11 is a through hole opened along the axis of the connecting member 1; the two second threaded holes 12 are relatively opened in the connecting member 1 with the first threaded hole 11 as the axis of symmetry to adapt to the installation of the accessory 2.

[0039] By designing the clips as a detachable assembly structure and designing the accessories based on their shape, accessories of different shapes can be freely selected in different construction situations to avoid the horizontal position conflict of the tension screws at the inner corners of two adjacent wall panels, thereby improving the quality of the formwork fixing installation.

[0040] like Figure 1a and Figure 1b As shown, each first clip 21 includes: a first body 211 and a bolt 212, wherein the bolt 212 is vertically fixed to the cross section of the first body 211; the first body 211 is screwed to the second threaded hole 12 on the connecting member 1 based on the bolt 212, so that the first clip 21 is installed on the connecting member 1.

[0041] like Figure 1a and Figure 1b As shown, each second clip 22 includes: a second body 221 and a bolt 222, wherein the bolt 222 is vertically fixed to the back of the first body 211; the second body 221 is screwed to the second threaded hole 12 on the connecting member 1 based on the bolt 222, so that the second clip 22 is installed on the connecting member 1.

[0042] In this embodiment, Figure 1a As shown, the longitudinal section of the connecting member 1 is preferably T-shaped; Figure 1b As shown, the shape of the connector 1 can also be other shapes, as long as it can accommodate the buckles 100 and the screws 200 at both ends.

[0043] In another embodiment, please refer to Figures 4 to 6 The present invention also provides a tension screw rod, which comprises a screw rod 200 and two clamping members 100 as described above, wherein the two clamping members 100 are screwed onto the screw rod 200 based on the first threaded hole 11. Figures 1a to 3 Due to the different selection of accessories 2 in the clamp 100, the shapes of the clamps 100 are different. Therefore, the shapes of the two clamps 100 are the same or different, and can be freely selected according to the actual location of the tension screw construction application. For example, when the horizontal position of the tension screws at the inner corner of two adjacent wall panels conflicts, in order to avoid the conflict, a clip of a suitable shape is selected to ensure the template fixation construction operation. For details, please refer to Figure 6 .

[0044] It is understandable that when the positions of the screws do not conflict during the installation of the conventional working template, the clamp 100 can be assembled according to the conventional installation method of the screw 200 to achieve the effect of fixing the template.

[0045] like Figure 4As shown, in the prior art, the clamps on the tie screws are all integrally formed mountain-shaped clamps 100', and two mountain-shaped clamps 100' are relatively sleeved on the screw 200' to form the tie screws. The tie screws are of a single shape, so there is a situation where the tie screws at the inner corners of two adjacent wall panels conflict in the horizontal direction, resulting in the inability to install the tie screws, affecting the installation of the template. Figures 5a to 6 As shown, the clip 100 designed by the present invention is assembled from multiple parts, and its shape is variable and more flexible. When it is applied to the tension screw, you can freely choose to match the clip 100 of different shapes according to the actual construction location requirements (actually, the shape change is achieved by selecting the accessories 2 that constitute the clip 100). According to the spacing of the screw holes reserved in the outer leaf wall on site, the clip 100 suitable for template installation can be processed to avoid the horizontal position conflict of the tension screws at the inner corners of two adjacent wall panels, thereby effectively improving the quality of template fixing installation.

[0046] In addition, after the concrete pouring is completed and the conditions for demoulding are met, the mountain-shaped clamps can be removed in sections by bolts 212 and 222 and used to install and fix the next layer of formwork (that is, they can be recycled), saving construction costs.

[0047] It can be understood that the above examples are merely examples listed for a better understanding of the technical solutions of the embodiments of the present application, and are not intended to be the sole limitation on the embodiments.

[0048] Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required for this application.

[0049] Obviously, those skilled in the art may make various modifications and variations to the utility model without departing from the spirit and scope of the utility model. Thus, if such modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalents, the utility model is intended to include such modifications and variations.
