[0034] In addition, if these terms "first", "second" appear, these terms are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, if the term "multiple" appears, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise specifically limited.

For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise specifically defined. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0036] In the present application, unless specifically defined otherwise, if there are similar descriptions such as "on" or "under" the second feature of the first feature, the meaning can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium.

[0038] The foundation is an important part of the test bench, which is used to provide accurate positioning and stable support for the test bench of the test equipment. The traditional test bench usually uses cast iron plates or cast steel / cast iron tracks that are leveled by secondary pouring as the foundation.
[0039] However, for large test equipment, due to the large power of the equipment, the tensile / compressive force transmitted from the test equipment to the foundation is one to two orders of magnitude higher than that of small and medium-sized test equipment, so the traditional cast iron plate and track foundation structure cannot meet the strength requirements of large equipment on the foundation; and the cast iron plate and track foundation structure may cause the embedded part to fall off and affect the equipment work due to insufficient embedding depth when bearing a large tensile force; the test bench area of large equipment test is usually two to four times that of traditional test benches, and if the traditional foundation design scheme is adopted, the cast iron plate or track needs to cover all the area, which has a large construction cost and increases the construction difficulty and prolongs the construction period.
[0040] To this end, an embodiment of the present application provides a bolt-embedded foundation 10 for positioning and supporting large experimental equipment or other large equipment, and of course can also be applicable to the positioning and supporting of small equipment. As shown in Figure 1 , the bolt-embedded foundation 10 includes a support module 100, an anchor plate module 200, and at least one pouring protection module 300.
[0041] The support module 100 is a support component of the bolt-embedded foundation 10 and is mainly used to support the anchor plate module 200 to lift the anchor plate module 200 to the design elevation. The support module 100 can be a welded structural member. In an embodiment, as shown in Figure 2 , the support module 100 can include a mounting platform 110 and a plurality of support columns 120; the mounting platform 110 is used to mount a modular mounting frame 210, and the support columns 120 are arranged below the mounting platform 110 and are height-adjustable. By arranging the height-adjustable support columns 120, the position (i.e. height) of the support module 100 can be adjusted to lift the anchor plate module 200 to the design elevation, and the levelness of the support module 100 can also be adjusted to provide an installation plane for the anchor plate module 200 that basically meets the requirements.
[0042] As shown in Figure 2 , the support column 120 can include an upper support column 121 and a lower support column 122; the upper support column 121 is connected to the mounting platform 110, and the lower support column 122 is below the upper support column 121 and is connected to the upper support column 121 through a plurality of first threaded members 123 to adjust the height of the support column 120. Specifically, as shown in Figure 3 , the outer peripheral surface of the lower end of the upper support column 121 is circumferentially provided with a plurality of fourth connecting lugs 170, and the outer peripheral surface of the upper end of the lower support column 122 is circumferentially provided with a plurality of fifth connecting lugs 180; the fifth connecting lugs 180 are connected to the corresponding fourth connecting lugs 170 through the corresponding first threaded members 123. When the height of the support column 120 is lifted to the design height, the first threaded members 123 and the nuts can be used to lock the upper support column 121 above the lower support column 122.
[0043] To facilitate the adjustment of the height of the support column 120, as shown in Figure 3 , one of the lower end of the upper support column 121 and the upper end of the lower support column 122 is provided with a guide sleeve 124, and the inner cavity of the other one is used to accommodate the guide sleeve 124. The guide sleeve 124 can guide the sliding of the upper support column 121 to facilitate the adjustment of the height of the support column 120. As an example, the lower end of the upper support column 121 is provided with the guide sleeve 124.
[0044] Referring to Figure 4In an embodiment, the mounting platform 110 is connected with the modular mounting frame 210 by vertical third screws 140 to adjust the height of the modular mounting frame 210 (described below) of the anchor plate module 200. The third screws 140 can not only mount the modular mounting frame 210 of the anchor plate module 200 on the mounting platform 110, but also adjust the height of the modular mounting frame 210 of the anchor plate module 200. The third screws 140 can be arranged around the mounting platform 110 to ensure the connection strength between the mounting platform 110 and the modular mounting frame 210 of the anchor plate module 200. As shown in Figure 4 , the mounting platform 110 is provided with a plurality of sixth connecting lugs 190 arranged around the mounting platform 110. As shown in Figure 5 , the modular mounting frame 210 of the anchor plate module 200 is provided with a plurality of seventh connecting lugs 250 arranged around the modular mounting frame 210 of the anchor plate module 200, and the seventh connecting lugs 250 are connected with the corresponding sixth connecting lugs 190 by the corresponding third screws 140.
[0045] Continuing to refer to Figure 4 , in an embodiment, the support module 100 further comprises a plurality of first positioners 130 arranged around the modular mounting frame 210, and the first positioners 130 comprise first connecting lugs 131 arranged on the mounting platform 110 and second screws 132 threadedly connected with the first connecting lugs 131, wherein the second screws 132 are horizontally arranged and abut against the modular mounting frame 210. The horizontal position of the modular mounting frame 210 can be adjusted in four directions (front, back, left and right) by the cooperation of the plurality of first positioners 130. During construction, the horizontal position of the anchor plate module 200 can be adjusted by the first positioners 130 first, and then the height of the anchor plate module 200 can be adjusted by the third screws 140, so that the adjustment of the six degrees of freedom in three directions (horizontal and vertical) of the modular mounting frame 210 can be realized.
[0046] The anchor plate module 200 mainly plays a role of anchoring the embedded bolt, and the embedded bolt can be a "T" bolt. As shown in Figure 5As shown, the anchor plate module 200 can include a modular mounting frame 210 and a plurality of anchor plate pieces 220, the modular mounting frame 210 is arranged above the support module 100 and is used to mount the anchor plate pieces 220, the upper end of the anchor plate piece 220 has an opening 220a and the lower end is closed. The modular mounting frame 210 mainly provides support for the anchor plate piece 220 and provides sufficient rigidity, which facilitates the lifting and adjustment of the anchor plate module 200 during production, transportation and installation. The anchor plate module 200 is adjusted for the position and flatness of the anchor plate piece 220 during production, ensuring the relative position and the height deviation accuracy of the upper surface of each anchor plate piece 220 on the modular mounting frame 210, so that when the construction is carried out, the entire anchor plate module 200 can be directly installed on the installation platform 110 of the support module 100, without the need to separately install and adjust the anchor plate piece 220 on the construction site, which can reduce the construction time.
[0047] In an embodiment, the anchor plate piece 220 is adjusted in position by a vertical fourth threaded member and a horizontal fifth threaded member. During construction, the horizontal position of the anchor plate piece 220 can be adjusted by the fifth threaded member first, and then the height of the anchor plate piece 220 can be adjusted by the fourth threaded member, so that the adjustment of the six degrees of freedom in the horizontal and vertical directions of the anchor plate piece 220 can be realized. The vertical fourth threaded member can also be used to mount the anchor plate piece 220 on the modular mounting frame 210.
[0048] Referring to Figure 7 In some embodiments, the anchor plate piece 220 can include an anti-seepage box 221 and an anchor plate 222 covered on the top of the anti-seepage box 221, and the opening 220a penetrates the anchor plate 222 in the vertical direction. The opening 220a is used for the head 20 of the embedded bolt to pass through and be fixed in the upper end of the anti-seepage box 221. As shown, Figure 5 The opening 220a can be a "one" shaped opening 220a. Referring to Figure 7 During construction, when the embedded bolt is lifted into position from the anti-seepage box 221, the head 20 of the embedded bolt reaches the upper end of the anti-seepage box 221, at which time the extension direction of the head 20 of the embedded bolt is perpendicular to the extension direction of the opening 220a. It should be noted that, Figure 7 The dashed box in the figure represents the head 20 of the embedded bolt.
[0049] As shown, Figure 6 or Figure 7As shown, the anti-seepage box 221 is provided with two limiting blocks 223, which are arranged along the extension direction of the diagonal line of the opening 220a, and the limiting blocks 223 are used for limiting the circumferential position of the head 20 of the embedded bolt. When the tail of the embedded bolt is pulled upward, the head 20 of the embedded bolt can move to between the two limiting blocks 223, and the limiting blocks 223 can limit the circumferential position of the head 20 of the embedded bolt, so as to avoid the head 20 of the embedded bolt from being dislocated and falling out of the opening 220a of the anchoring plate 222 during the tightening process.
[0050] Further, referring to Figure 6 or Figure 7 , the anti-seepage box 221 is further provided with two guide plates 224, which are arranged below the corresponding limiting blocks 223, and are used for moving the head 20 of the embedded bolt upward to between the two limiting blocks 223. The head 20 of the embedded bolt can move upward along the guide plates 224, and will not move to between the two limiting blocks 223 in an unreasonable posture, so as to avoid the situation that the embedded bolt is not tightened after being lifted into position. The unreasonable posture of the head 20 of the embedded bolt can be Figure 8 The dashed box in Figure 8 represents the head 20 of the embedded bolt. In order to better play a guiding role, the guide plates 224 can be inclined plates, and the distance between the two guide plates 224 gradually increases from top to bottom.
[0051] The pouring protection module 300 is used for avoiding the penetration of concrete mortar into the anchoring plate 220 during pouring, so as to ensure that the head 20 of the embedded bolt can move in the anchoring plate 220. As shown in Figure 1 , each pouring protection module 300 includes a plurality of connected pouring sheaths 310, and each pouring sheath 310 is in communication with the upper end opening 220a of the corresponding anchoring plate 220, so that the head 20 of the embedded bolt can pass through the pouring sheath 310 and be fixed in the upper end of the anchoring plate 220. Since the pouring sheath 310 also has position and perpendicularity requirements during construction and installation, the pouring sheath 310 is pre-assembled into a pouring protection module 300 matched in size with the anchoring plate module 200 during production, so as to reduce the working time of installing and adjusting the pouring sheath 310 on the construction site.
[0052] When the bolt embedded foundation 10 is in service, the test equipment will apply a certain size of pulling / pressing force to the embedded bolt, so in some embodiments of the present application, the axial length of the pouring sheath 310 can be set according to the size of the pulling / pressing force borne by the embedded bolt, so that the bolt embedded foundation 10 can meet the requirement of the strength of the foundation of large equipment, and can also avoid the embedded bolt from falling off when a large pulling force is borne, so as to affect the work of the test equipment. The pulling / pressing force borne by the embedded bolt can be at least one of the axial force and the shear force.
[0053] When expressed as an axial force, the axial length L of the pouring sheath 310 can be calculated according to the following formula:
[0054] L=F1 / (k x τ1)
[0055] Wherein, F1 in the above formula is the maximum axial force borne by the embedded bolt; k is the material resistance coefficient of the pouring sheath 310; τ1 is the axial tensile stress of the concrete.
[0056] When expressed as an axial force and a transverse shear force at the same time, the axial length L of the pouring sheath 310 can be calculated according to the following formula:
[0057] L=F2 / (k x τ2)
[0058] Wherein, F2 in the above formula is the maximum shear force borne by the embedded bolt; k is the material resistance coefficient of the pouring sheath 310; τ2 is the shear stress of the concrete.
[0059] Of course, considering that in actual engineering, the embedded bolt anchor is usually subjected to the action of axial force and shear force at the same time, therefore, a comprehensive calculation is required, and the following formula can be used:
[0060] L=max[F1 / (k x τ1), F2 / (k x τ2)]
[0061] In an embodiment, the lower end of the pouring sheath 310 is connected to the corresponding anchor plate member 220 through a sixth threaded member. Wherein, the lower end of the pouring sheath 310 is provided with a sixth connecting lug plate, and the sixth connecting lug plate is screwed with the sixth threaded member. In order to provide a good field of view for observation equipment (such as a total station, a theodolite) during the process of precisely adjusting the anchor plate member 220, the pouring sheath 310 is designed as a detachable structure. During construction, the anchor plate module 200 can be installed on the support module 100 first, and then the pouring protection module 300 is installed on the corresponding anchor plate member 220 by using the sixth threaded member.
[0062] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.
[0063] The above-described embodiments are merely illustrative of several embodiments of the present application, which are described in more detail and in a specific manner, but should not be construed as limiting the scope of the patent application. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
